Indian couple invent fuel-less, battery-less auto engine

Kolkata couple invent fuel-less, battery-less auto engine. Interesting that the advances/new technology are able to gain support, instead of being bought out by a petrol car manufacturer and left idle on the bench. clipped from economictimes.indiatimes.com Kolkata couple invent fuel-less, battery-less auto engine KOLKATA: Kanishk Sinha, 30, and his
wife Lipika, 25, chose to do something different from looking for
jobs—they invented a fuel-less environment-friendly auto
engine.


"This engine is switched on by a chemical reaction between
zinc and oxygen; hence it is pollution-free. This technology also increases the
durability of the engine," Kanishk Sinha, chairman of the Jasper Motor Vehicle
company, told reporters.

"A water pump can run for five years without any interruption
on this engine and a four-wheeler car can run 450,000 km," said
Sinha.

The young couple established the company registered in the US
five years ago with Rs.1 billion (Rs.100 crore) raised from non-res…

CVS Short Notes And Useful Commands For Daily Usage

CVS Short Notes And Useful Commands For Daily Usage
Creating a directory tree from a number of files

When you begin using CVS, you will probably already have several projects that can be put under CVS control. In these cases the easiest way is to use the import command.

An example is probably the easiest way to explain how to use it. If the files you want to install in CVS reside in ‘wdir’, and you want them to appear in the repository as ‘$CVSROOT/yoyodyne/rdir’, you can do this:

$ cd wdir
$ cvs import -m "Imported sources" yoyodyne/rdir yoyo start

Unless you supply a log message with the ‘-m’ flag, CVS starts an editor and prompts for
a message. The string ‘yoyo’ is a vendor tag, and ‘start’ is a release tag. They may fill no purpose in this context, but since CVS requires them they must be present


Adding files and folder to CVS individually

To add a folder or file to CVS repository in some existing path, follow these steps.

For example, you want to create a folder “nuport” inside t…

Game Theory Explains Why You Can’t Hurry Love

It shows that extended courtship can take place, with a good male being willing to court for longer than a bad male and the female delaying mating. In this way the duration of a male’s courtship effort carries information about his type. By delaying mating, the female is able to make some use of this information to achieve a degree of screening. Because bad males have a greater tendency to quit the courtship game early, as time goes on and the male has not quit it becomes increasingly probable that he is a “good” male. clipped from www.sciencedaily.com Scientists have developed a mathematical model of the mating game to help explain why courtship is often protracted. The study, by researchers at UCL (University College London), University of Warwick and LSE (London School of Economics and Political Science), shows that extended courtship enables a male to signal his suitability to a female and enables the female to screen out the male if he is unsuitable as a mate. The research uses gam…

Hack your brain

DO YOU EVER want to change the way you see the world? Wouldn't it be fun to hallucinate on your lunch break? Although we typically associate such phenomena with powerful drugs like LSD or mescaline, it's easy to fling open the doors of perception without them: All it takes is a basic understanding of how the mind works.

You Can Look - But Don't Touch

That's what the phenomena of shopping spree based on. When they start to use scientific approach to us, which they calling marketing techniques, we have no chance. Much worst when they doing it secretly and in the final end we are realizing that our money clipped from www.sciencedaily.com
Researchers from Ohio State University and Illinois State University tested
how touching an item before buying affects how much they are willing to pay for
an item.  A simple experiment with an inexpensive coffee mug revealed that
in many cases, simply touching the coffee mug for a few seconds created an
attachment that led people to pay more for the item. 
The results, which were published recently in the journal Judgment and
Decision Making, found that people become personally attached to the mug within
the first 30 seconds of contact.  “By simply touching the mug and feeling it in their hands, many people begin to feel like the mug is, in fact, their mug.  Once they begin to feel it is theirs, t…
