Toyota announcing a plug-in Prius in the future...


Dear EarthTalk: I understand that Toyota is planning to sell a plug-in Prius that will greatly improve the car’s already impressive fuel efficiency. Will I be able to convert my older (2006) Prius to make it a plug-in hybrid vehicle? -- Albert D. Rich, Kamuela, HI
Toyota is readying a limited run of a plug-in Prius, which can average 100 miles per gallon, for use in government and commercial fleets starting in 2009. Toyota will monitor how these cars, which will have high efficiency lithium ion batteries that haven’t been fully tested yet, will hold up under everyday use.
Essentially, a plug-in version of the Prius reverses the roles of the two motors under the hood. The regular Prius relies more on its gas engine, switching to (or combining) use of the electric motor in slow traffic, to maintain cruising speed, and when idling or backing up. The car doesn’t need to plug in because its battery stays charged by the gas motor and by the motion of the wheels and brakes. The plug-in will primarily use its electric motor, allowing commuters to go to and from work every day fully on the electric charge, saving the gas engine for longer trips that exceed the distance the car can go on electricity alone.
Toyota has made no announcement yet as to when consumers will be able to buy a plug-in; that depends largely on the results of the field test of the fleet version. But owners of a current or past model don’t need to wait. Those with automotive mechanical skills can convert their Priuses to plug-ins themselves.
“The conversion is an easy DIY [do-it-yourself] project that you can do for about $4,000, if you choose to use sealed lead acid batteries,” says Houston-based Jim Philippi, who converted his Prius last year, using instructions he downloaded for free from the Electric Auto Association’s PriusPlus.org website. Philippi recommends that DIYers consult Google’s RechargeIT.org as well for useful background information.
For those less inclined to a DIY, several companies now sell readymade kits (some also have kits for converting Ford Escape Hybrid SUVs). Ontario-based Hymotion sells plug-in kits for Prius model years 2004-2008 for around $10,000 via contracted distributors/installers in San Francisco, Seattle and elsewhere. Other providers include Plug-In Conversions Corp., Plug-In Supply, EDrive Systems, Energy Control Systems Engineering Inc. and OEMtek. All typically work with select garages that specialize.
One potential worry about conversions is whether or not Toyota will honor the warranty that came with the original vehicle. The California Cars Initiative (CCI), which has converted several hybrids to plug-ins for research and demonstration purposes (sorry, they’re not for sale), says the carmaker needs to clarify the matter, since hybrid cars typically have four or five separate warranties. There is legal precedent, CCI says, that modifications cannot completely void warranties—only the part(s) affected by a retrofit.
If you’re looking to convert, keep in mind that such a move is not about cost-savings, as it will take some time for fuel savings to justify the upfront cost of even a DIY. Most people interested in such a conversion are doing it for the sake of the environment, not their pocketbooks।

Brain Pacemakers.....



Brain cells, called neurons, communicate with one another through electrical impulses.
In deep-brain stimulation, a battery implanted in a person’s chest delivers steady pulses of electricity to a targeted area of the brain. The artificial current interrupts or corrects dysfunctional electrical activity that is causing medical problems. Doctors can tailor the speed, strength and length of the pulses to get the desired result.
Well established as a way of quelling the tremors that can afflict people with Parkinson’s disease, deep-brain stimulation is showing promise for a host of other ailments, including chronic pain and depression.
The video is brief, just a couple of minutes, but it’s reality TV as riveting as anything you’ll ever see. A man in his mid-50s, affable, articulate, faces the camera and talks a bit about a medical procedure he’s had. He holds in his hand what looks like a remote control. “I’ll turn myself off now,” he says mildly. The man presses a button on the controller, a beep sounds, and his right arm starts to shake, then to flap violently. It’s as if a biological hurricane has engulfed him, or perhaps it’s that his arm is made of straw and some evil sprite is waving it about. With effort, the man grasps the malfunctioning right arm with his left hand and slowly, firmly, subdues the commotion, as if he were calming a child in the throes of a temper tantrum. He’s breathing hard, and it’s clear he can’t keep it up much longer. With an almost desperate gesture, he reaches out for the controller and manages to press the button again. There’s a soft beep, and suddenly it’s over. He’s fine.
Composed, violently afflicted, then composed again. All with the flick of a switch. As before-and-after moments go, this one is potent, verging on the miraculous. It’s the kind of thing you’d expect to witness under a revival tent, not in the neurology ward of a British hospital. Once you’ve seen it, you’ll have an indelible image of Parkinson’s disease. The word “tremor” doesn’t convey what can happen to people—the way they are thrashed and harassed by their own bodies. But this scene, involving a patient of ours, informs viewers about more than a disease; it’s a vivid window onto a powerful medical technology known as deep-brain stimulation (you can watch the video at www.kringelbach.dk/nrn).
Sudden, radical transformation is the hallmark of deep-brain stimulation. The treatment, essentially a pacemaker for the brain, consists of a deceptively simple two-part device. A surgeon threads one or two thin wires into carefully selected locations deep within the brain, then inserts a small battery just underneath the skin near the collarbone. Pulses of electricity travel from the battery to four electrodes situated at the tip of each wire. The effects are instantaneous, usually appearing while the patient is still on the operating table—the quieting of a tremor, the ability to walk again or, in some patients with otherwise treatment-resistant depression, a renewed energy for life.

Features Impact and the Brain
Deep-brain stimulation came into its own in the 1990s, and since then surgeons have performed it on more than 35,000 people, mostly to quell Parkinson’s disease and other movement-related disorders. It is not a cure, but it can keep symptoms at bay for years. Recently, as the electrodes have become safer and the batteries smaller and longer- lasting and as advances in brain-imaging techniques such as magnetic resonance imaging have made it possible to place electrodes with greater precision, neurosurgeons have begun investigating the technology as a way to ease a host of other health problems.
The technique has made it possible for children with a disabling movement disorder called dystonia to leave their wheelchairs and lead nearly normal lives. It has brought immediate relief to people suffering from cluster headaches and other kinds of unremitting pain. It has shown tantalizing promise for some psychiatric disorders, including severe cases of depression, obsessive-compulsive disorder and Tourette’s syndrome. It has been attempted as a cure for anorexia and obesity. Some neuroscientists speculate that it could help stem the memory loss brought on by Alzheimer’s disease. The brain is an electrical organ, so there is little that goes wrong with it that could not, hypothetically, benefit from finely calibrated pulses of electricity. Clinical trials of deep-brain stimulation—preliminary testing on small groups of patients—are multiplying at hospitals around the world, from Cleveland and Toronto to Bristol, Grenoble and Milan.
Despite the recent advances, technologically speaking, deep-brain stimulation is not yet fully mature. Today’s devices are programmed to deliver steady, unchanging pulses of electricity. Over the next decade we expect to see a much “smarter” device, one that would turn itself on and off as needed, tailoring its therapy to what is happening moment to moment in the patient’s brain.
The Body ElectricOften when people want to make a difficult task seem easier, they say, “After all, it’s not brain surgery.” And for good reason. Although we know a lot about the brain, there is still a lot of mystery packed into the three pounds of wrinkled tissue that house a human consciousness, and we neuroscientists must proceed with a combination of humility and hubris.
But deep-brain stimulation has an advantage over most other kinds of neurosurgery—namely, it is reversible. If the electrodes malfunction or if they are simply ineffective, they can be turned off or removed. The procedure is not without risk—1 to 3 percent of patients experience bleeding that leads to a stroke, and a slightly larger number develop treatable infections. Unlike most surgeries, however, deep-brain stimulation does not change the physical structure of the brain; electricity does all the work.
Awareness of the role of electricity in the body dates to A.D. 43, when Scribonius Largus, court physician to the ancient Roman emperor Claudius, wrote that headaches and gout could be soothed by the touch of the torpedo fish, which emits an electrical charge when startled. In 1774 Benjamin Franklin noted that static electricity can lead to muscle contraction, and a decade later Italian physician Luigi Galvani observed that by applying electricity to the sciatic nerve he could make the leg of a dead frog twitch in a lifelike manner. His breakthrough inspired Mary Shelley’s Frankenstein, in which a monster cadged together from parts of dead people was animated by a massive electrical charge.
Galvani’s discovery did more than ignite sci-fi fantasies; it ushered in a host of medical advances. In 1870 German neuropsychiatrist Eduard Hitzig and anatomist Gustav Fritsch selectively manipulated the limbs of a live dog by stimulating specific areas of the brain region now known as the motor cortex—in other words, they showed that each muscle of the body, every finger and toe, is controlled by electrical impulses from a dedicated patch of brain tissue. In the 20th century researchers had the tools to investigate the cellular level. They deciphered how electricity travels through a single brain cell, or neuron, and from there to its neighbor, creating the complex networks that dictate our thoughts, actions, memories and desires.
Before long, investigators asked: But what happens when those neural networks short-circuit? In the 1950s and 1960s neurosurgical pioneers, including Natalia Bechtereva in the U.S.S.R., Robert Heath of Tulane University and J. Lawrence Pool of the Neurological Institute of New York, began experimentally applying electricity to the brains of people suffering from chronic pain, depression and movement disorders. The batteries then available were much too large to be implanted, so the devices were kludgy and the relief, sporadic. Still, these investigations established a medical precedent for targeted electrical pulses.
Parkinson’s disease turned out to be an ideal proving ground. In this disorder, neurons die off in a brain area that coordinates movement, the basal ganglia. In a healthy brain, neurons in the basal ganglia communicate in an intricate call-and-­response with groups of neurons in other areas, including the thalamus and the motor cortex. For movements to be quick and fluid, these parts of the brain must work together. Messages traveling between them are called oscillations. They bounce back and forth, moving at different frequencies, some serving to initiate movement, others, to moderate it. But what is key is that the sender and recipient neurons, like two girls rhythmically swinging a jump rope for a third to hop over, must be in sync. In Parkinson’s, diseased neurons lose their ability to keep up, and the oscillations become unbalanced. Neurons fire wildly, and a person moves in a chaotic way or is unable to initiate movement at all.
In the late 1980s surgeons found that if they stimulated either the thalamus or the globus pallidus (a part of the basal ganglia) with fast pulses—up to 180 times per second—they could override the faulty connections. Scientists do not completely understand how deep-brain stimulation works, but we do know that the pulses sent to the electrode sometimes drive and sometimes inhibit the natural activity of neurons. Faster pulses, such as those used in Parkinson’s patients, tend to overwhelm and thus inhibit activity, whereas slower pulses tend to drive it by creating a tempo that the neurons strive to meet.
Working with monkeys that had been given parkinsonian symptoms, one of us (Aziz), as well as other teams led by neuroscientists Mahlon R. DeLong of Emory University and Abdelhamid Benazzouz of the Bordeaux Neuroscience Institute in France, helped to establish that another part of the basal ganglia, the subthalamic nucleus, can be an even more effective implantation spot (it has since become the most popular stimulation target). More recently, Aziz discovered a fourth target for the 20 percent of Parkinson’s patients who do not respond to medication or to stimulation in the three established brain regions. After observing that a part of the brain stem called the pedunculopontine nucleus was underactive in a parkinsonian monkey, Aziz showed that stimulating this area brought stunning results to human patients for whom until recently nothing could be done. Many people who would otherwise be freezing in mid-step or falling over find themselves suddenly able to walk again.
Thanks to this kind of research and to the fact that the requisite batteries are now as small as the ones in cell phones, more than 250 hospitals in the U.S. alone perform deep-brain stimulation for movement disorders. Although other applications are considered experimental, in part because they are not yet approved by the Food and Drug Administration, strong evidence is mounting in their favor. Take, for example, the treatment of pain. Over the past 30 years more than 700 people have had deep-brain stimulation for otherwise treatment-resistant pain; the average long-term success rate is 60 to 70 percent, and when doctors are skilled in patient selection, the success rate approaches 100 percent.
A Sudden Calm Descends In May 2001 a man named Robert Matthews fell and broke his left leg. The fracture did not heal properly, and the leg developed a stubborn antibiotic-resistant infection. Fearing that it would spread, doctors amputated his leg above the knee, but Matthews’s problems did not end there. Although his leg was gone, he felt as if it were still there and in excruciating pain. He tried medications, hypnosis and stimulation of the spinal cord nerve, but nothing helped.
When Matthews was referred to us, he was 58 years old and had been suffering from phantom-limb pain for four years. He was taking large daily doses of opiates and, understandably, felt anxious and depressed. We had previously shown that stimulation of the brain stem, the most ancient part of the brain, can ease otherwise treatment-resistant pain; Matthews seemed an ideal candidate.
On the day of the surgery, our team clamped Matthews into a stereotactic frame—a metal rectangle that surrounds the head and provides three-dimensional coordinates for any point within the brain. We scanned his brain twice—with MRI before the frame was attached (metal objects are unsafe in an MRI machine) and with computed tomography afterward—and used software to merge the images. Like a nose or a foot or any other body part, the brain varies slightly from person to person, so structures deep within it will not always be found in exactly the same location. Now Aziz had a personalized map he could use to plot his trajectory with millimeter precision.
Matthews received an injection of local anesthesia so that he would not feel Aziz drill a small hole in his skull. There are no nerve endings in the brain itself, though, which meant Matthews could be fully awake—and we would need his participation to make the hour-long operation come off. Aziz gently guided a wire tipped with four platinum-­iridium electrodes through the jellylike brain tissue and into the area known as the periventricular gray/periaqueductal gray (PAG). While methodically electrifying first one, then another, of the four electrode prongs, Aziz asked Matthews to describe out loud what he felt.
This is one of the trickiest moments in deep-brain stimulation—banishing the symptom without causing side effects by accidentally activating the wrong spot. The electrode is only about a millimeter and a half wide, but it straddles up to a million neurons. Packed tightly within the PAG are cells that communicate with each part of the body; we wanted to affect only those related to Matthews’s left leg. If he reported feeling tingling or warmth in his hands, arms, face or other leg, Aziz would move the electrode, stimulate a different prong or change the pulses. Moreover, we were prepared for reactions even further afield. The PAG is the seat of the so-called fight-or-flight response, and in the past we have had a patient suffer an anxiety attack on the table. Side effects that can result from imperfect electrode placement in other parts of the brain include eye bobbing, inappropriate laughter and depression.
We gave Matthews a relatively mild amount of current: 1.5 volts—the strength of an AA battery. As for the speed, or frequency, of the pulses, we knew that fast pulses make pain worse, so we started him at about 10 per second and ultimately settled on seven. When we stimulated two of the prongs at these specifications, Matthews felt a sudden calm descend—a comfortable feeling of warmth in his phantom leg. After four years, finally, relief.
Aziz affixed the electrode-tipped wire to Matthews’s skull and implanted a battery over his right pectoral muscle. The battery connects to the electrode by a lead that runs under the skin of Matthews’s chest and neck and behind his ear to his scalp. Matthews has a magnetic remote control to turn the deep-brain stimulator on or off—but he rarely uses it, because as soon as he does, the agony returns. He reports that his pain is 75 percent reduced, and he has been able to resume his life.
Good as that outcome is, in the future we should be able to do better, using technology similar to that of today’s cardiac pacemakers. Computer software in these devices monitors the patient’s heart, sending a jolt of electricity only when it recognizes that the heart is not beating properly. When brain pacemakers become this precise, they will not have to be on all the time, which means, among other things, that the batteries will not have to be changed as often (they currently typically require surgical replacement every six months to five years, although rechargeable batteries are also starting to become available). Before deep-brain stimulation can advance, however, scientists must decode the language of neurons. We need to learn the details of how brain regions communicate, such as which electrical patterns might signify an oncoming tremor, headache or epileptic seizure. Then we can program the device to recognize when a problem is coming on and to deliver the specific pattern of pulses that will short-circuit it. Our team has made an intriguing advance toward discovering just such a “brain signature”, and other studies are under way.
The Hype and the PotentialThe transformative power of deep-brain stimulation is especially striking in the psychiatric realm. Investigators in Toronto, Leuven, Bonn and elsewhere have been enthusiastically reporting results from small trials. There is the report of a 31-year-old man who had such violent tics from Tourette’s syndrome that he could not get a decent job or go out in public without being snickered at, whose body suddenly relaxed. There is the story of a woman whose world literally became brighter—looked newly washed—as soon as the electrode was activated. Other depressed patients said their sensations of “painful emptiness” disappeared. These changes abruptly vanished when patients’ electrodes were switched off.
This is heady stuff, given that we do not understand exactly how deep-brain stimulation works nor do we know for sure what goes wrong in depression, Tourette’s or many of the other syndromes for which stimulation is being attempted, such as obsessive-compulsive disorder, anorexia, overeating and drug addiction. There is potential here—the work on depression in particular seems promising. But some scientists are getting ahead of themselves, and the media have been delighted to assist. In August 2007 neuroscientists at New York–Presbyterian Hospital/Weill Cornell Medical College and the Cleveland Clinic Foundation received lots of attention when they reported using deep-brain stimulation to wake a 38-year-old man from a minimally conscious state. Six years after a brutal beating, the man can eat without a feeding tube and speak a few words, an undeniable improvement. But the fact is that Japanese neurosurgeons have experimented for decades with deep-brain stimulation for just this kind of patient and found that such revivals are rare.
In another recent incident, a man undergoing experimental deep-brain stimulation to treat obesity incidentally retrieved a long-forgotten memory, whose clarity intensified when doctors turned up the voltage. Consequently, some have expressed optimism about brain implants for Alzheimer’s. The problem is that deep-brain stimulation is a relatively blunt tool—it either inhibits or excites a brain region (and in turn, the other brain structures that region talks to). That is fine for Parkinson’s, in which an overactive brain area may need quieting. But in Alzheimer’s what we see are neurons that lose their connections to one another and can no longer store memories. It is unlikely that deep-brain stimulation could repair such intricate connections.
Perhaps contributing to all the excitement about deep-brain stimulation is the fact that it is more than a promising therapy. It is a powerful tool neuroscientists can use to gain insights into the fundamental structure and function of the brain.
Until now our best view of the living human brain has been through imaging studies such as MRI and positron-emission scans, but what we get from them is vague, along the lines of “When a person does such-and-such or thinks such-and-such, there are changes in blood flow or oxygenation in certain parts of the brain that are likely related to changes in neural activity.” With deep-brain stimulation, on the other hand, what you essentially have is an on-off switch located in a specific part of the brain. By observing what happens to the brain as a whole when that switch is activated, you can glean detailed information about how various brain structures interconnect. One particularly exciting avenue that we have pioneered is to combine deep-brain stimulation with an imaging technique called magnetoencephalography (MEG). MEG tracks neural activity on the scale of milliseconds (MRI, in contrast, gives average brain activity over a six-second period and PET over a scale of minutes), providing an exceedingly accurate, moment-to-moment report.
When we used this technique on Matthews, the phantom-limb patient, we saw that the electrode in his brain stem appeared to drive activity in many other brain regions. Among the most active when he felt pain relief was the midanterior orbitofrontal cortex. This structure, located just above the eyes, has been shown in other studies to play a pivotal role in pleasurable (or rewarding) activities such as eating, using drugs and sex. Thus, cessation of pain is an intense form of pleasure, along the lines of snorting a line of cocaine or devouring a delicious pastry. This finding confirms that the orbitofrontal cortex might be an effective new stimulation target for people suffering from anhedonia, a lack of pleasure, which is common to depression and other mental illness.
We expect more revelations. By studying people with brain implants, we might answer questions such as how the brain coordinates learning a new language or solving an algorithm. We might even get new big-picture perspectives, such as how something as elusive as subjective experience can arise from electrical activity. Perhaps most important, we will be able to identify the brain areas where electrical stimulation will be most effective, further helping patients in dire need.

Have we learnt any Lesson?

We have still not learnt any lesson! Probably we have been still acting to insulate ourselves from the possible threats arising due to the recent terror strikes in the economic city of the country,Mumbai.
Being a Sunday,Today I chanced upon to visit the places where terrorists have hoisted the flag of Jihad, be it Taj Mahal Hotel, Leopold cafe or the VT station to name a few. I found that the things were as usual as before. The police was seemingly idle and least worried about to check the passers by. We were three guys hav
ing three bags each. I was carrying a bag full of 10 books. We entered the VT station hoping that our bags would be checked as a part of high-alert surveillance but none cared to even throw a view. Though I have found that Malls have been really reactive and sensitive. All the visitors are checked thoroughly even my wallet was checked. That's a good thing. But I think about a situation if someone enters a Malls with a Automatic Machine Gun in hand and spilling deadly bullets all over then will these poor G-4 security chaps who are unarmed would be able to stop them? 
At the VT station though they are armed but they are not very possessive about the security of the venue.
The good thing which I discovered over my day long journey that people are quite worried and behaving sensitively. The destinations of massacre have been quite become an icon of historical monuments as I saw the people including me staring the cordoned off Hotel Taj, gossiping with each other.
We could easily locate the marks of bullets at Leopold cafe where I astonishingly saw the youths enjoying the unconsciousness of Beer. The cafe was jam-packed. Though there was a seemingly tension which was prevailed all over. The foot-path vendors were not very aggressive to sell their cheap products as they usually were during my last visits.
In a nutshell I feel its the insensitivity of the government in vision as well in action to avoid such embarrassing situation in the future.

End of the day I am worried and my face carries a sadistic look.

CAble TV stands for......

Cable television is a system of providing television to consumers via radio frequency signals transmitted to televisions through fixed optical fibers or coaxial cables as opposed to the over-the-air method used in traditional television broadcasting (via radio waves) in which a television antenna is required. FM radioprogramming, high-speed Internettelephony and similar non television services may also be provided.

The abbreviation CATV is often used to mean "Cable TV". It originally stood for Community Antenna Television, from cable television's origins in 1948: in areas where over-the-air reception was limited by mountainous terrain, large "community antennas" were constructed, and cable was run from them to individual homes.

Towards a Divide....

Terror strikes in India do come as an untimely rain every now and then. The entire country is put on high alert post these attacks. The ministers do their jobs by passing a sadistic note to the media with an assurance that they will not allow the anti-social elements to terrorise our nation in any way further. The people sitting in the opposition do a spot survey added by counter attack on the failure of National Security Agency and off course target the ruling government. We too forget these pathetic incidents after a little while as we have become maniacs to these shocking events. Now what to do, should we wait for one another terror strike or do something really useful for the nation?
Today everyone is well aware of the fact that the backbone of our political system has become so corrupt that it can't afford the weight of the security of the Great Hindustan. Sometimes I got frightened by thinking of a possibility that our nation is heading towards a great divide. We all have become so self centered and lost the true feeling of being an Indian. We have just cornered our feelings to the Air-conditioned 70 mm screens of the multiplexes where we enjoy watching bollywood films like Rang de Basanti to recently colored Naya Daur. Have popcorn and Pepsi and enjoy for the 200 bucks that we have paid; with a feeling of directed Nationhood which flows in our blood temporarily which lasts for 3 hours at most.
It is very sad to explain in words that the current Indian westernised breed has no strength of its own! We lack good leaders and a vision.
I condemn the recently happened serial of unwanted events that rocked the economic city of India, Mumbai. I have no regrets to say that it is not only the politicians but also the aam-aadmi is responsible for these attacks. I can't spare the Navy also that how they didn't notice the said entry of the terrorists in India through Indian Ocean. Were they sleeping that time? For what they are paid? The so called Indian sleeping tigers are not at all comparable in competency with respect to the active Pakistani Pigs. Why our defence minister has dared to take his job for granted? Should we remind him that that there are much more things to do other than just playing cards for his party? I herewith blame the media also for broadcasting the filtered and money churner news only.
The recently much hyped probe of Malegaon has overshadowed the Batla House Encounter and other incidents. Why? It clearly hints towards a dirty political influence.
To cut the long story short I will simply say that with this kind of system and this kind of inhabitants including me we are heading towards a big instability and a divide for which we all will be responsible.
Jai HIND!

Mahatma Gandhi inspires Obama.....

Obama also flaunts his love for the apostle of peace by having a portrait of Mahatma at his Senate Office!

Washington: Barack Obama, who today scripted history by getting elected as the first black President of the United States, has always seen Mahatma Gandhi as an inspiration who reminds him about the “real message of life”.
Obama also flaunts his love for the apostle of peace by having a portrait of Mahatma at his Senate Office.
The Democrat, who favours US having close links with India, has told an Indian magazine that he was “fortunate” to have close Indian-American friends and recalled the rural development work his mother did in the country.
Through the power of his example and his own unshakable spirit, Gandhi inspired a people to resist oppression, sparking a revolution that freed a nation from colonial rule, the Democratic Presidential-elect had said.
“Gandhi’s significance is universal. Countless people around the world have been touched by his spirit and example. His victory in turn inspired a generation of young Americans to peacefully wipe out a system of overt oppression that had endured for a century. “And more recently led to velvet revolutions in Eastern Europe and extinguished apartheid in South Africa,” the 47-year-old Senator from Illinois had said in his message on 2 October, birth anniversary of Gandhi.

बूझो तो जाने.......

My digital alarm clock has many responsibilities. First, it has to wake me up at 6:30 A.M. to get my kid to school. Later, I reset it for the various 10-minute naps I take during the day.Resetting the alarm clock for a new time entails changing the hour one hour at a time on a 24-hour clock and then changing the minute value one minute at a time. In the worst case, the minute value must be changed by clicking 59 times. (As you can see, it's not an iPhone, Android or other device that allows me to key in the right time.)So, I thought that it would be nice to have an extra button that would advance the minutes by more than 1 with each click. The question then is: What number of minutes, as an interval, would be most efficient?Warm-up:Suppose the multi-minute button (MM for short) always advanced the time by 5 minutes. What, then, is the greatest possible number of clicks necessary to reset to the correct minute value?Warm-up solution
Problems:1. Still, 5 minutes may not be the best interval to choose for MM. What might be better for minimizing the worst-case number of clicks? What is that worst case?2. Suppose that the first click on MM advanced a certain number of minutes, the second click on MM a possibly different number of minutes, and so on. What should those numbers be to minimize the worst-case number of clicks?3. Suppose you were given two multi-minute buttons (MM1 and MM2), and each advanced the time by a fixed number of minutes. What should those two fixed numbers be for the two buttons to minimize the worst-case number of clicks? How many is that worst number?Hint: Suppose one button advanced the minutes by, say 32, then two clicks of that button advanced the minute hand by 4 without changing the hour value.
Puzzle solution
We now have three buttons that advance the time, one by 1 minute and the others by other amounts. Many variants are still possible. For example, we could take away the constraint that all buttons advance the time and the constraint that one of the buttons must advance by 1 minute. If you have a cool variant that you can solve, then please post it, with the solution, as a comment on this story.

NASA to Discuss Mission to Study Sun's Weakening Protective Bubble

GREENBELT, Md. -- NASA will hold a media teleconference on Friday, Oct. 17, at 1 p.m. EDT, to preview the Interstellar Boundary Explorer, or IBEX, mission. The spacecraft may confirm if the sun's protective bubble surrounding our solar system, called the heliosphere, is about to shrink and weaken. IBEX also will be the first spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space. The heliosphere acts as a shield for our solar system, warding off most of the galactic cosmic rays. Recent data indicate the solar wind's global pressure is the lowest seen since the beginning of the space age. IBEX is set to launch Oct. 19 from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. Panelists will be: - David McComas, IBEX principal investigator at Southwest Research Institute in San Antonio - Nathan Schwadron, co-investigator and IBEX Science Operations Center lead at Boston University - Stephen Fuselier, co-investigator and IBEX-Lo Sensor lead at Lockheed-Martin Advanced Technology Center in Palo Alto, Calif. - Eric Christian, program scientist at NASA Headquarters in Washington Reporters should call 1-888-323-5257 and use the passcode "IBEX" to participate in the teleconference. International media should call 1-415-228-4881. Supporting information for the briefing will be available at the start of the teleconference on the Web at:

Insulating Paint Powder Turns Every Color 'Green'

Remember that grade-school riddle, "What's black, white, and red all over?" Depending on who gave you the punch line, the answer was "a sunburned zebra" or "a newspaper." 

Here's an updated version: What's every color in the world, but still always green? 

The answer is paint that includes an insulating powder that originated at NASA. Widely used on commercial and residential structures, it transforms any color of paint into an environmentally friendly insulation barrier that saves energy and cost. 

The solution is simple: mix the powder into any color of interior or exterior paint, then break out the brushes. When spread on walls, ceilings, and roofs, it creates a barrier that deflects the sun's heat away from the house, plus it helps keep heating and air conditioning where they belong. This reduced need for energy is not only cost-effective, but also a kindness to the environment -- an easy way to create your own "green house effect." 
Many businesses use insulating paint to coat air-conditioning ducts, steam pipes and fittings, metal buildings, and cold storage facilities, such as walk-in coolers and freezers. For example, Purina Feeds uses a version of the insulating powder to cover storage silos, helping to prevent feed spoilage. The poultry industry uses it to help regulate the climate inside its hatcheries. Samsung applies it on military vehicles, and Hyundai Corporation's shipbuilding division paints it onto ships. It's even been used to insulate electrical switch boxes on the outside of fighters jets to prevent overheating. 
This simple but powerful solution all began with space shuttle launches. During a launch, heat generated by wind resistance and engine exhaust can potentially be very damaging. In the 1980s, engineers at the Marshall Center developed a spray-on process to apply an insulating mixture to help protect the shuttle. The process involved mixing nine different chemicals into an adhesive that was applied to the boosters' forward assembly, systems tunnel covers, and aft skirt. 

But there were challenges. Once the insulating material was mixed, it had to be applied within five hours. Any delay meant a batch of expensive materials was lost, requiring the time and cost to mix a new batch. The strength of the insulating material was also difficult to regulate, meaning it could chip during the shuttle's flight and splashdown of its reusable booster rockets. Adding to the downside, two of the nine ingredients in the insulating mix weren't environmentally friendly. 

In 1993, Marshall created a solution by atomizing epoxy and other filler materials to create a fine, environmentally friendly insulation powder. The material -- known as MCC-1, or Marshall Convergent Coating-1 -- contained tiny, hollow glass spheres and particles of cork and epoxy. The application process was also changed. Instead of mixing the insulating powder directly into the paint, it was shot from a spray gun at the same time the paint was applied. This change in process eliminated the five-hour "time clock" to complete the painting. 

The improved, eco-friendly insulation powder was first flight tested in 1996 on the STS-79 mission. It was so successful that it was adopted for all subsequent shuttle flights, with virtually no observed missing or chipped paint on the spent boosters during post-flight inspections. 
Bringing the NASA insulation powder to the public market resulted in an innovative partnership with Tech Traders, Inc. Months of testing and development created Insuladd®, a safe, non-toxic powder that can be added to any interior or exterior paint to transform it into a layer of insulation. 

The powder contains hollow, microscopic ceramic spheres, and a unique process applies a coating to these "microspheres." When the paint dries, it forms a radiant heat barrier, converting ordinary house paint into heat-reflecting thermal paint. 

You might say that NASA's contributions to insulating paint can keep green in your world AND in your wallet. That's a good reason to be tickled pink.

Please don't trust the Congressite Mussalmans, for they are not only the 'Mir Jafars amongst us.....

Thus writes a Khan Bahadur from Delhi"This is a letter for the Question Box in Harijan.In your article in Harijan of April 6, you observe as follows:
'I should be failing in my duly if I did not warn the Mussalmans against the untruth that is being propagated amongst them. This warning is a duty because I have faithfully served them in their hour of need and because Hindu-Muslim unity has been and is my life's mission."
I will request you to consider the Hindu-Muslim problem from our point of view. The stumbling block to any negotiations for a settlement of the communal question has been the refusal of the Congress to recognise the All India Muslim League as the authoritative and sole representative body of the Indian Mussalmans. The Congress claims that it speaks for whole India and that it has on its rolls a considerable number of Mussalmans. The very fact that the Congress has made several attempts to come to terms with Mr. Jinnah shows that it is not fully confident of its representative character as far as the Mussalmans are concerned, But do you not honestly feel that the Congress Mussalmans are the real stumbling block in the way of Hindu-Muslim unity, and that it is for their sake that the Congress is not making a serious effort to solve the problem? Believe me, they are a lazy lot who are enjoying their present position because they are in the Congress.
You know what the Muslim masses did to your President in Calcutta where for years he had been leading Id prayer. You also know that they have no courage to address a Muslim meeting to convert the Mussalmans to their point of view. You blame the British for creating Princes, Moderates and Khan Bahadurs like me. You blame the British for trying to create another Ulster in India. Has not the Congress created equivalent Moderates and Khan Bahadurs in Azads, Asaf Alis and Kidwais. Is not the action of the Congress tantamount to creation of a Muslim Ulster?
You may cite the case of Mr. Asaf Ali succeeding in the municipal elections of Delhi. I may inform you that but for a division in the Provincial league and bad handling of the situation Mr. Asaf Ali would have never won the election. I may inform you that even as it is, when Delhi Congress wanted to contest the municipal elections as a party, Mr. Asaf Ali, who is now a member of the Congress Working Committee, had declined to take a Congress ticket. Therefore, Mr. Asaf Ali's election was not a test case; and if, you pardon my saying so, even now let Mr. Asaf Ali re-seek election on a Congress ticket, and I am confident that any league candidate would defeat him. You will thus realise, that your being baffled by the Lahore resolution of the League is not. Justified when Mussalmans have ceased to trust in your file's mission regarding Hindu-Muslim unity. On the other hand they are convinced that the sole aim of the Congress, for the last ten years at least, has been to divide and rule the Mussalmans. I will beg of you to reconsider your attitude towards the League. Please don't trust the Congressite Mussalmans, for they are not only the 'Mir Jafars amongst us, but the enemies of Hindu-Muslim accord and India's freedom."
Just now I am inundated with letters of protest from Muslim friends. Most writers do not argue. They give themselves satisfaction by abusing Pyarelal, who opens and deals with the daily post, gives me only those letters which he thinks I should see. Of these I take notice of those I think I must. In some cases I answer them privately. Therefore correspondents who never receive acknowledgement either through Harijan or the post should know the reason.
There are some Muslim letters of sympathy too. One of them says that in his house he has to listen to wildest criticism of me. No adjective is too bad to use. Much criticism he knows to be false. What is he to do, he asks. Is he to leave the house, or is he to engage in endless disputation and convert his house into a bear garden? I have advised my correspondent neither to leave the house nor to engage in a discussion. If he can, he may put in a mild word when he knows that a manifest falsehood is being uttered and believed.
The correspondence in my possession and the Urdu press cuttings and even some English cuttings from journals owned by Muslims go to show that I am believed to be the arch enemy of Islam and Indian Muslims. If I was at one time acclaimed as their greatest friend and suffered the praise, I must suffer too to be described as an enemy. Truth is known only to God. I am confident that in nothing that I am doing, saying or thinking I am their enemy. They are blood brothers and will remain so, though they may disown me ever so much.
Now for the Khan Bahadur's letter.
I have never understood the reason behind the demand for the recognition by the Congress of the All India Muslim League as the sole and authoritative Muslim body. Why should such an admission be demanded or expected? How is it compatible with a genuine desire for a settlement?
The Congress attempts to represent all. But it has never demanded recognition as such from anybody. The all India status has to be deserved. But whether it be deserved or not, admission there of is a superfluity. The Congress has never claimed that it represents the whole of Indian Muslims. It has not claimed to represent any single community wholly. But it does claim to represent every single national interest irrespective of class, caste, colour or creed, Even that claim need not be admitted by those who deal with it. It should be sufficient consolation to each party that it is considered by the other important enough to seek friendship with.
The Congress has always frankly admitted that it has not on its register as many Muslims as it would like. But it has been proud to have had the support of many eminent Muslims. Hakim Shaheb Ajmal Khan was the tallest among them. Qaid-e-Azam himself was a great Congressman. It was only after non-cooperation that he, like many other Congressmen belonging to several communities, left it, Their defection was purely political. They disliked direct action.
It is wrong to swear at the nationalist Muslims simply because they are attached to the Congress. If they become members of the League, they will become worthy Muslims!!! My correspondent simply does not know how much Congress Muslims are trying to bring about unity. When unity is re-established, as it must be, I have no doubt that nationalist Muslims will get their due both from Hindus and Muslims.
It is torture of truth to suggest that they are so many Mir Jafars. They are betraying neither Islam nor India. They are as true Muslims according to their lights as members of the League claim to be, It is equal torture of truth to suggest that the Congress is following the British method of divide and rule. The Congress is a political party with one single aim. It would be a bad day for India if the Congress could be proved to have mean motives. Is it mean to woo Muslim opinion by the fairest means imaginable? Rightly or wrongly the Congress does not believe in watertight compartments on a communal basis. If religion is allowed to be as it is, a personal concern and a matter between God and man, there are many dominating common factors between the two which will compel common life and common action. Religions are not for separating men from one another, they are meant to bind them. It is a misfortune that today they are so distorted that they have become a potent cause of strife and mutual slaughter.
It will perhaps now be clear why I can have no concern with Asaf Ali Saheb's case. I would grant that he would be beaten in a contest between him and a Leaguer. let it be further granted that such will be the case in the majority of such contests. It will in no way weaken my position. It will prove the superior organizing ability of the League and its popularity among the Muslims. I have not doubted either. My case is incredibly simple. I must not be called upon to make any admissions about the status of the League before thinking of unity through the League. I must not be disloyal to the Muslim nationalists however insignificant they may be considered to be. I ask the Khan Bahadur, the writer of the letter under discussion, to exert his influence to bring the two communities together.

a fight for right!

It was just another joyride along with my family to one of the most exotic beaches of Maharastra, Divyaagar located in the district of Raigad. I along with my brother, sister-in-law and my sweetest niece were returning from Harihreshwar and decided to spend some of the unforgettable moments at the mile long beach at Divyaagar under the sauna of the Almighty Sun. We all were so tired after a long drive from Harihareshwer to Divyaagar that we decided to have a lunch first before submerging ourselves in the waves of the splendid Indian Ocean. A MTDC resort run by one private Mumbai Based group Exotica fitted the bill as it lied just closest to the beach. Not to mention I found the beach as one of the best beaches in India comparable to famous Kovlam Beach at Kerala, which I had visited around four years back. Back at MTDC Resort the best in the beach city we ordered lunch. We preferred to have Mineral Water instead of Regular one. The food was delicious beyond expectations. We asked for the bill. The bill totaled a sum of INR 325. I scanned the bill and a sleeping Indian Citizen immediately got a catalytic pill started reacting in my blood. The Mineral Water bottle was charged for INR 25 a bottle which was INR 12 above from the MRP. You would be thinking that what strange is in this order of routine. But my dear friend it is illegal to sell any item above the Maximum retail Price. I retaliated. I felt a Gandhi inside me and did a “dandi march” deep in the depth of my heart. I asked the attendant who reluctantly referred to the manger who tried to convince me that what wrong is with me. Everywhere in the country at the star places items are sold above the MRP. I simply asked him to give me a bill mentioning the name of the brand and sign the same. The guy got a shiver from inside he immediately called his superior and talked to him on the matter. The Phone was handed over to me and I took the charge of the invisible battalion and put my simple point before the senior manager who was actually the Incharge of the Resort. He immediately smelled his malpractices and apologized me and finally I extra amount was deducted. I felt that time my heart had beats for India only. Money was not the issue it was the issue of the malpractice which we generally ignore in our routine life as the amount is not big. Though I tipped off the waiter as a gesture but something which is wrong at the moment was not acceptable to me. Later I moved to beach and gave a thought sitting amidst the neck rubbing waters of the non-ending ocean. This was a small battle which with God’s grace I had won. I had many more battles that I have to fight. I pray to God that He give me a strong and robust spirit to fight all those honestly. Signing off!

U.N. says credit crisis could enable "green growth"

By Patrick Worsnip
UNITED NATIONS (Reuters) - Instead of sidelining the fight against climate change, the global credit crisis could hasten countries' efforts to create "green growth" industries by revamping the financial system behind them, the U.N. climate chief said on Friday.
But that would depend on governments helping poor countries -- who are key to saving the planet's ecology -- tackle their problems, instead of spending most available money on rescuing the financial world, Yvo de Boer told reporters.
De Boer said the financial "earthquake" that has seen markets plunge worldwide in recent weeks could damage U.N.-led climate change talks, but only "if the opportunities that the crisis brings for climate change abatement are ignored."
"The credit crisis can be used to make progress in a new direction, an opportunity for global green economic growth," de Boer, who heads the Bonn-based U.N. Climate Change Secretariat, told a news conference.
"The credit crunch I believe is an opportunity to rebuild the financial system that would underpin sustainable growth ... Governments now have an opportunity to create and enforce policy which stimulates private competition to fund clean industry."
De Boer said a successful outcome to climate change negotiations in Copenhagen in December 2009 would create new markets, investment opportunities and job creation.
But he warned that "if available global capital is used primarily to refloat the financial world, we literally will sink the futures of the poorest of the poor.
"And I hope that the credit crunch will not mean that people in the South will have to wait for those in the North to have repaid their credit card debts and mortgages before attention is again turned to the South."
Without reaching out a hand to developing countries, it would be very difficult to make advances on the rest of the environmental agenda, De Boer said.
Environment ministers will meet in two months' time in Poznan, Poland, to prepare for the Copenhagen summit, which is due to agree on a new global-warming accord to succeed the Kyoto Protocol, which expires in 2012.
Ministers in Poznan must make clear they were "willing to put financial resources, the architecture, the institutions in place that will allow developing countries to engage in a global approach on both mitigation and adaptation," he said.
Funding did not have to all come from governments and he foresaw "an approach where we very much use the market".
De Boer said the financial crisis had not so far affected the Kyoto Protocol's Clean Development Mechanism, which allows rich countries to offset their carbon footprints by investing in clean energy projects in developing countries.
"I don't see a slowdown in the CDM pipeline at the moment," he said.

Reverse Mathematical Objects!




Newton’s third law: For every reaction there is a reaction, this is a Universal law! Today I will try to prove it mathematically. But still I am not sure of that how it exactly will be applicable practically. During normal thinking hours some seconds proved to be useful and productive which I would like to share with you through my blog! Only the great Almighty knows that whether I would be able to solve the riddle of life or not in my life time. May the Almighty enlighten me!
First draw a circle on x and y axis:-

Here we are analyzing that how the points on the perimeter of the circle behave wrt x and y coordinates! We start from (r,0) and finishes at (r,0) after taking a full anti-clockwise round. Here we intend to analyze the points on perimeter from minimum to maximum wrt to x and y coordinates.
Tabulating this:-


Now if we try to draw the points on any axis as (Min,Max) from first quadrangle to IV quadrangle then we find the flow of the coordinates as Clockwise.
Initially we have drawn the circle in a anticlockwise direction or we have drawn the circle from minimum to maximum in anticlockwise direction. But during mathematical analysis we found that minimum to maximum wrt to any of the coordinates do lies in clockwise direction. It is very interesting to note here that there exists a mathematical drama(U-Turn) here. It may be a reality too!
The same will apply to z and t axis also.
So, behind our every move it is proved at least mathematically that there exists a parallel negative factor also.
If we say the Universe is expanding then there would exist negative volumes also in the Universe. Or we also can’t deny the assumption that Universe is expanding with a rate of –dv/dt creating black holes if v is substantially almost equal to infinity or vice versa.
The derivation is quite simple but gives birth to a very interesting theory of “Reverse Mathematical Objects”.

the RAVE Parties!

In the recent times the word Rave Parties has influenced the media in a big way. I don’t exactly understand why the issue has attracted too much of a lime-light in a society where our Sadhus and Mahatmas are found taking happy narcotic drugs. I remember my 3 day long stay at Mahakumbh, Allahabad held in 2001 where I got the opportunity to understand the very native essence of Hindu religion practiced in modern times. Many of our ancient temples are full of pictures of naked gods and goddesses. I found many babas taking deep puffs of ganja and charas and enjoying their bharamacharya on the ghats of the Ganges. I too adventured to reserve a puff for myself and tried to understand the world from their view of thinking. Infact I later only regretted the decision but anyways it was good for the sake of first cut experience. During my entire stay and interaction with the people of different muths I didn’t find anything praiseworthy that I can talk of my religion once I am out of the created pious scene. I found the visiting pilgrims as scoundrel as in routine life. While taking bath in the holy rivers they were more concerned about the safety if their holding that they have left at the ghats. There was no respect for the senior citizens that they should be given the chance first and must be obliged physical help. I was also not a different being altogether and I remember the night of Shivaratri, it was 4:00 AM in the morning and a bit raining. I was all alone and wanted to take a bath in the holy preliminary hours of the festival. But I was worried about my polythene bag that I was carrying. I scanned the entire ghat to form a covalent bond with someone. With God’s grace I didn’t have to waste much time and I finally got me. I handed him over my belongings and went straight to the river to take a holy dive. Though all the way I was terrified lest these people flee away as I was barely wearing only an undergarment. During the period I was restless as all my money was with the Good Samaritan and if I lost touch with him after I return then I would have to do a naked parade on the streets of Allahabad! Fortunately things were all in order and I succeeded to go back to my hostel which full honor. End of the day I thought that when my heart contributed even a single second to pray to god when I was amidst the flowing waters of Ganga? Like me there a millions of followers who sail in the same boat. I firmly believe no one can be expected to function and act as a 100% right man. There is a Ravana hiding in each one of us!
The current rave party is no more a exception. Our culture is going westernized so the people. At one time in USA the LSD was so popular that the users had formed a big community in itself. Remember the famous bollywood song “Hare Rama, Hare Krishna”
I will not advocate the usage of such drugs as it is for sure that we are running towards our end but we should visualize the problems in totality. Why the FTV and XX movies not banned in India? Why the pubs and bars are allowed to operate? Why the government is no so forceful in implementing the laws if any strictly? Infact behind the successful organization if these Rave Parties we are all involved some where.
I had also chanced upon to visit a Rave Party (just today I realized) last year at dharamshala. The so called sacred divine home for Holy Dalai Lama. The person who is fighting against the Chinese government for the freedom of Tibet. He has used the method of Gandhi ie Non-Violence. I interviewed various localities there who had a firm faith in the method of Gandhi practiced by Dalai Lama. But bounced back whether Mr. Lama is fighting a spiritual war or a diplomatic one? He is enjoying the luxuries of the life far away from the region of problem and talking about its’ freedom. He is scared of going to China as Chinese may get hold of him. I would like to react sharply that it is not a true Gandhian way. I agree that they are non-violent but there hardly I see any struggle for the Freedom. Gandhi was the person who sacrificed all the luxuries, traveled in third class and was the first person to reach the ailing state; whatever the consequences. Dalai Lama wants to get the freedom diplomatically. He may prove to be right in his method but I request him not to compare his method with that of Gandhi.
I was shocked to see the young Tibetans staying there. The night life of Dharamshala was as romantic as Las Vegas. You will find many Tibetan youths going hand in hand with the visiting foreigners and enjoying their nights with them at their expense. The Rave Parties are common there. I saw a topless foreigner girl kissing a young Tibetan at a dark corner of the room. And this was not the only example!
I thought at the moment that where Dalai Lama is paving his youths to? Do they ever be able to get the freedom by indulging in such heinous acts? Their first and foremost mission should be to work towards the achievement of the freedom and that needs sacrifice of high level if they want it through non-violence.
Interesting an Indian is not as respected as a foreigner in Dharamshala as we Indian are poorer to visiting videshies, though Mr. Lama and his pupils are living in exile in India.
I appeal him to do something for his nation and integrity before he dies rather than allowing his persons to fall into this western fashion of Rave Parties!

the bleeding ORISSA!

India is screaming again. The same old devil has attacked again the very intact culture of the nation. I am talking of Orissa where the shameless acts have put a big question mark on the sanity of the religion Hindu. Are the majors in some danger from someone? Is this a fight to save the religion or a game of betting where “Shakuni mama” has set his dices well and the loser side has to pay up in the form of “draupdi”? It’s a bad blame game again played not for the first time in the history of human-being. The minorities have always been oppressed and the majors feel that as they are doing some great service to their gods or their country. Our parents spend millions of seconds to make us a good man but even a single second does not contribute to kill the hiding “Shakuni” inside us. Probably we are better off playing with the nuts of others. Throwing light on the current cooked up scene some 42000 Christian families have been deprived of their home; some 55 churches have been set ablaze, 35 killing and last but not the least the one shameful rape of a nun which questions the teachings of the religion. If we Hindus feel that raping someone is a solution to their worries then I willfully say that the followers of this religion should be banned and should be seen as an underdeveloped race. The chaps are still living in the Stone Age. Their integrity is of no more of a dog which runs after the passers by without having any sense. The “aakaas” of the religion have a responsibility to keep their facilitators under control. If they can’t do it then better they should wash off their hands of the responsibility of leading such religions. This does not applies to Hindus only but also to the Muslims too. Some of the Moslems have done so derogatory act that I again willfully call them another street Dog. These monkeys have made the mockery of the very spirit of the pious human being. They have left no stone unturned to tarnish the core values of the human race. I am against of any type of violence performed in the name of the religion. Though the Christians too have a not a very good past. We have seen over the time that how there has exists a screeching line between the whites and the blacks. The only intention to rule someone else is the biggest evil we people nurture in our mind. We forget the fact that we should have a firm faith in the concept of Love ALL. Let all people be treated on equal footing. There should be no difference in the basic ingredients of the religious and cultural dishes though presentations may vary.
It is highly regretful on the part of the government both state as well as the center that they made an insignificant delay in resolving the matter। I am sorry for those politicians who may try a failed attempt in naming this delay as Indianised one. Let me finish this article with a message to all those unsocial polluters that for a glorified India, for a glorified religion and most important for a glorified human-being we all need to glorify our good inner spirits first and rest will take care of itself.

REACTIONS invited!

It’s not the congress or UPA it’s the Honorable HRD minister Mr. Arjun Singh again. He had hit the hot iron again. The politician in real meaning has done his job. Did his best to reserve his seat in the seat if the UPA comes back in power at least. He has played the cards smartly though out his tenure as HRD minister. But has he done it right by taking another regretful decision of increasing the Income Cap for Other Backward Class to 4.5 lacs from 2.5 lacs presently?
Mixed reactions? Some take it for good for their better but for some it is worst than worse! The government has again proven on account of Mr. Arjun Singh that somewhere down the line it political interests matters more than the National Interests. Seems that there is an appeasement department working underground for the government headed by the honorable HRD Minister! This is not the first time when Mr. Singh has not gone against the right wind that flows to the nation to the path of right democracy.
Government can hang me if I say that acts of Mr. Singh are not only shameful but also anti-nationalist. For certain political interests he is doing all the acts that an obliged dog has to perform for his master.
I assume Mrs. Sonia Gandhi and our Prime Minister Mr. Manmohan Singh are quite sensible in understanding the true patriotic desires of the nation. If they like to keep their eyes closed then my nation doesn’t require them. Let me be clear that my nation is not hungry of these power-savvy politicians be it the leader of opposition party Mr. Advani or Mrs. Sonia Gandhi. It’s the call and voice of a natural Indian. An Indian soul and soil will never allow anyone to divide the nation on the basis of cast or religion. Being a secular nation all are equal, all are the spirits of One God.
I am not against the reservation. There should be a provision in the Indian Constitution to provide equal footing to the underprivileged. But compare peers with peers, is Mr. Singh really observing this?
A country where more than 40% of the people are living below the poverty line with an annual income of roughly Rs.25000 a year can a person 450000 a year be certified as underprivileged by the government of India?
The equation is out of my intelligence!
But it is true and it is happening.
We all Indians including me again have to follow the path shown by Great Mahatma. Just publishing some advertisements in the newspapers financed by the hardworking taxpayers will not suffice. We should keep in mind that we have no right including me to voice against anyone without contributing anything to the nation literally. Even writing an article like this is just a most coward and useless act performed by an average Indian.
You will even find some more and better article on the newspaper next day.
On the path shown by Mr. Gandhi we have to prosecute a non-violent non-cooperation movement against the government. Time has come when we all need to stand up against these corrupt politicians.
The current of the so called honorable Union HRD Minister shows that they are least bothered about being an Indian first than a politician.
Our politicians have learnt a good thing from British that divide and rule. These unfortunate chaps are great in following this rule.
So my friends time has come when the entire youth has to show his strength. Dare to stare in the eyes of these power-hungry politicians. Let we make them realize that Indians are no more a dull fools. They are no more their hand-puppets!
But this is not an easy path. Just words are not enough, you need a courage and good understanding from your inner spirit. A feeling of utter devotion is required to the service of the Nation. You may have to leave your jobs, your friends may call you a dumb-fool, your family may stop you from doing this, and your financials may go in a deep black-out!
Be Ready! If you really want some change, otherwise for God’s sake stop criticizing the politicians like a favorite time pass.
If you have the will then go ahead. I am always with you just give me knock!
REACTIONS invited!

The roaring spiritual lion!

Catch hold of your breath! Just seal close your lips. Let bundle your thoughts to an infinite zero. Make sure your movements are silent. If possible try to chain your heart beat too as it too can vibrate the environment and echo some unwanted decibels.
Rub your footsteps carefully that you have left behind, lest some trail should put you in some difficulty. If you walk avoid any synchronization with your mate as it can give birth to resonance. Your life is in danger!
But why? My life has no potential dangers! I have no enemies. I do practice and own good attributes that a human being should own. So what kind of danger you silly guy is talking about.
Don’t go with the literal meaning just. I meant the essence of your life is in danger. The greatness of humanity over its peers is in danger. As the day passes you are loosing the rights to be called a king in justice of the entire living society. Your insane virginity is being hackneyed by some evil powers.
You mean I would no longer be able to rule the world and I will be raped by someone!
To some extent, Yes!
But how and who the bloody hell is going to dare to even touch me?
Your own spirit my little kid!
But why the spirit has become its own enemy?
It has all right to do whatever with you and you are just powerless before the Excellency of the Holy Spirit. The holy spirits starts acting at the time when you start ignoring the inherent powers of the spirit and begin challenging it altogether. Every moment passed it develops a Horoscope of yours and writes punishments for you which you have to accept willingly of unwillingly.
Oh my God! The God should not have created this spirit. This is like we all are some living Bombs. God has made a blunder.
The so called blunder of God has saved you from the millions of unknown blunders that could have cropped up if there would have no spirit.
How?
Each of you would have become your own GOD. The fight of the supremacies would have ruled out the rule of some single rule which is a must. Though you have now started writing your own rules and the only penalty is that you should be punished bloodlessly.
You have made your own rules and divided the entire humanity based upon color and races. You love to smell the taste of blood. You love to deny the rule of nature. You love to do brutality. You love to criticize your own brothers. You love to manipulate the truth.
You love to judge the things on the scale of violence. You see peacekeepers as a shame to masculinity. You know why all this is happening!
Because you JUST LOVE ONLY YOURSELF!
Beware the spiritual lion is nearing you roaring. May be the next minute you may be no more. Think if all you can’t even become a history? The lion is blind. Though his senses are quite strong He can smell your evil nature.
So be prepared before you perish!

In the name of Osama!

27th sep! The year was 2008, 12 years behind, when the India will become the Superpower. I mean the our great nation is targetting to be a SUPERPOWER till then!
Looks a Joke seeing the present scenario?
Serial blasts in the major cities in India rocked the entire nation.
Today I feel that these unsocial elements are doing these cowardly acts not in the name of Allah but in the name of Osama.
Yes Osama! These maniacs do take the terrorism not only as a profession but also as their leisure time activity.They are doing these mean activities for their fun. They love to see the blood.They have misinterpreted the Holy Quran?
And these people can kill me if I say that the Holy Quran is useless if it is motivating them to do such inhuman activities.
Time has come when the entire world who protests against the terrorism should come together and preach the right meaning of the Holy Quran to the world.
I sincerely feel there should be no religion but there should be only one thing that is Science which should govern the world.
I declare at this moment,I may be wrong that at least Science is not inhuman.It is above all the mean ideas that these religions give birth!
Osama has become a thinking which is just maligning the very holiness of the Quran. That must be stopped.

Invention: Infrared lie detector

Although security services the world over have used lie detectors to lock many people up over the years, they are not very reliable. However, a new way of scanning brain activity may change that.

The long-established polygraph test measures a person's respiration rate, heart rate, and perspiration. The idea is to detecting anxiety associated with guilt or lying.

But simply being anxious – about, say, being interrogated – can produce similar signals, and some people may be able to learn to beat the test. By some accounts, the results from such tests are no more accurate than guesswork.

Bouncing light
Measuring brain activity directly is though to be a more promising approach. This is currently achieved using technologies such as functional magnetic resonance imaging or EEGs.

But these methods have disadvantages of their own. For example, EEGs provide only a very low resolution picture of brain function, and fMRIs are hugely expensive, while scans are ruined by small movement of the subject.

Scott Bunce, at Drexel University's College of Medicine in Philadelphia, thinks a better solution is to send near-infrared light through the scalp and skull into the brain and see how much is reflected back. And he has designed a special headband that does just that

Blood simple
The amount of reflected light is dependent on the levels of oxygen in the blood, which in turn depends on how active the brain is at that point.

This, he says, gives a detailed picture of real-time activity within the brain that can be used to determine whether the subject is lying. The technique is both cheaper and easier to apply than fMRI and gives a higher resolution than an EEG.

A similar approach is being used to investigate Alzheimer's disease.

Of course, nobody knows whether brain activity can reliably be decoded to reveal deception, but that's another question.

Gender differences seen in brain connections!

Human brains appear to come in at least two flavours: male and female. Now variations in the density of the synapses that connect neurons may help to explain differences in how men and women think.

Even when intelligence levels are equal, women and men excel at different cognitive tasks. But although brain size and neuron density differ between the sexes, these don't seem to correlate with cognitive differences. So, Javier DeFelipe at Complutense University in Madrid, Spain, and colleagues counted the number of synapses instead.

The brain tissue they analysed came from the left temporal cortex, a region of the brain involved in emotional and social processing, of four women and four men with epilepsy. The tissue itself was healthy, having been removed to allow doctors to access underlying damaged areas.

The men had up to 52% more synapses per brain "layer" in this region than the women. While the effect of high synaptic density in this region is unknown, the team suspects that there may be other regions where women out-synapse men.

In any case, says DeFelipe, although different synaptic densities indicates different circuitry between men and women, men shouldn't get too cocky: the density of synapses in mice is greater than in humans.

Can smells sweeten your dreams? Certain aromas, such as lavender, are known to have soporific effects, but once you’re asleep, can smells influence what you dream about?

To find out, Boris Stuck of University Hospital Mannheim, Germany, exposed 15 sleeping volunteers to chemicals that mimicked the smell of either rotten eggs or roses.

"Most everyday smells have two components: the actual smell and a component that irritates your nose," says Stuck. "By exposing the patients to chemicals chosen to only incorporate the smelly component, we were able to stimulate them with really high doses of the smell without them waking up."

Stuck's team waited until their subjects had entered the REM phase of sleep, the stage at which most dreams occur, and then exposed them to a high dose of smelly air for 10 seconds before waking them up one minute later. The volunteers were then quizzed about the content of their dreams and asked how it made them feel.

Rose-tinted dreams
All subjects reported a positive dream experience when stimulated by the rose smell, and most experienced the opposite when exposed to the rotten eggs. Stuck says the smells influence the "emotional colouration" of the dream.

The team are now looking to recruit people who suffer from nightmares to see if exposure to smells can help make their dreams more pleasant.

"The relationship between external stimuli and dreaming is something we are all at some level aware of," says Irshaad Ebrahim of The London Sleep Centre. "This initial research is a step in the direction towards clarifying these questions and may well lead to therapeutic benefits."

Stuck is presenting his work on Sunday at the American Academy of Otolaryngology's annual meeting in Chicago

Did the Romans destroy Europe's HIV resistance?

THE hand of history has a very long reach. It appears that the Roman Empire left a legacy that may still affect modern Europe - those living within its conquered lands are more susceptible to HIV. It could explain why a gene that confers resistance to HIV varies in frequency across the continent.

The gene in question codes for a protein receptor called CCR5. The HIV virus binds to this receptor before entering cells. One gene variant, called CCR5-Delta32, has 32 DNA base pairs missing and produces a receptor that HIV cannot bind to, which prevents the virus from entering the cells. People with this variant have some resistance to HIV infection and also take longer to develop AIDS.

Generally, only people in Europe and western Asia carry the variant, and it becomes less and less frequent as you move south. For example, more than 15 per cent of people in some areas of northern Europe carry CCR5-Delta32, compared with fewer than 4 per cent of Greeks (see map). It is not clear why this is so, since the HIV pandemic - which began in the early 1980s - is too recent to have influenced the distribution of the variant.

However, the changing frequency of the variant reflects the changing boundary of the Roman Empire from 500 BC to AD 500, says Eric Faure at the University of Provence in Marseille, France. When Faure and colleague Manuela Royer-Carenzi investigated possible links between Roman colonisation and the frequency of the CCR5-Delta32 variant in nearly 19,000 DNA samples from across Europe, they found that the gene variant seemed to dwindle in regions conquered by the Romans (Infection, Genetics and Evolution, DOI: 10.1016/j.meegid.2008.08.007).

Alternative theories include the idea that the protective variant originated in Scandinavia, and was spread north and east by the Vikings. But the pattern of Viking migration does not match the current distribution of the variant. Another theory is that a major disease, such as plague or smallpox, created a selection pressure on the gene variant which increased its frequency. But its distribution does not match that of disease outbreaks, either.

So how did the Romans lower resistance across Europe? Some studies suggest that they and other southern Europeans had lower levels of CCR5-Delta32. But Faure does not think that the Romans spread the regular version of the gene into their colonies by breeding with indigenous people. "Gene flow between the two was extremely low," he says.

Instead, he reckons the Romans introduced a disease to which people carrying the CCR5-Delta32 variant were particularly susceptible. As the Romans moved north, this disease killed off people with the variant.

Faure notes that the Romans introduced cats and donkeys into Europe which may have carried pathogens that spread to humans.

What's more, the Romans inadvertently brought with them disease-carrying mosquitoes. Intriguingly, modern people with the CCR5-Delta32 variant are more susceptible to the mosquito-borne West Nile virus.
