SD College
SD College
was started by the Sanatan Dharm Sabha, Barnala, in May 1956. The college, besides imparting instruction up to Three-Year Degree Course (Arts and Science), also Provided training under the National Cadet Corps and National Service Scheme. It is compulsory for Pre-University and Three-Year Degree Course Part I students to take one of these subjects. The college encourage the students to take healthy interest in games and sports. A few culture and literary societies and associations are functioning the college. It has laboratories, a library with a book and a reference section and an auditorium. It also publishes its magazine ‘Stream’ annually.
The students of this college are eligible for the award of all types of University, Government and other scholarships

 

Shri Lal Bahadur Shastri College, Barnala

 

Shri Lal Bahadur Shastri College was started in June 1968, in the memory of late Prime Minister, Shri Lal Bahadur Shastri, by the local Arya Samaj. The college, besides preparing students up to Three-year Degree Course (Arts Group), also provides training under the National Cadet Corps. And National Service Scheme. The college encourages sports the students for which there is good arrangement.
The college has a library and a book bank to assist the Scheduled Castes and other deserving students. Besides, a number of cultural and literary societies and functioning in the college. It brings out its magazine ‘Manogya’ annually. The students of this college are eligible for the award of all types of university, government and other scholarships.
 

 

Revised Theory Suggests Carbon Dioxide Levels Already in Danger Zone

The authors, who include two Yale scientists, assert that to maintain a planet similar to that on which civilization developed, an optimum CO2 level would be less than 350 ppm — a dramatic change from most previous studies, which suggested a danger level for CO2 is likely to be 450 ppm or higher. Atmospheric CO2 is currently 385 parts per million (ppm) and is increasing by about 2 ppm each year from the burning of fossil fuels (coal, oil, and gas) and from the burning of forests.  

“This work and other recent publications suggest that we have reached CO2 levels that compromise the stability of the polar ice sheets,How fast ice sheets and sea level will respond are still poorly understood, but given the potential size of the disaster, I think it’s best not to learn this lesson firsthand.”
The statement is based on improved data on the Earth’s climate history and ongoing observations of change, especially in the polar regions. The authors use evidence of how the Earth responded to past changes of CO2 along with more recent patterns of climate changes to show that atmospheric CO2 has already entered a danger zone.

 

Controlling the flow of heat could be another way to store digital information

 

Someday, computers might store information using not only electric charges or magnetism, but also tiny packets of heat called phonons. Such heat-based memory is theoretically possible within the laws of physics, new research shows, and this memory would be durable and could be read without destroying the information — two key requirements for useful data storage.

Circuits based on quantum packets of heat rather than electric charges could enable computers to use waste heat — which is currently just shed to keep a processor from overheating — to perform useful computations and store information. A surge of research in the last few years on the physics of controlling the flow of heat packets has yielded designs for heat-based diodes, transistors and logic gates that perform AND, OR and NOT operations.

Unlike the electrons in an electric circuit, phonons in a thermal circuit are not actually particles. Instead, phonons are discrete units of vibration among the atoms in a solid. The stronger these vibrations are, the hotter the solid will be. In materials that conduct heat, phonons travel through the substance just as electrons travel through electrical conductors.

Concentrated heat normally tends to dissipate over time, which would seem to make heat-based memory impossible. Normally, heat flows faster when the temperature difference between two materials is greater, which is why a red-hot burner will heat a pot of water faster than a burner on medium. But the team previously showed that materials can be designed to work in the opposite way, so that a greater temperature difference causes heat to flow more slowly. This reversed response is what allows phonons at one of two temperatures — representing the “on” or “off” of digital memory — to stay at that temperature long enough to make the thermal memory useful.

 

Violent Video Games Affect Boys Biological Systems

 

In the study boys (12-15) were asked to play two different video games at home in the evening. The boys’ heart rate was registered, among other parameters. It turned out that the heart rate variability was affected to a higher degree when the boys were playing games focusing on violence compared with games without violent features. Differences in heart rate variability were registered both while the boys were playing the games and when they were sleeping that night. The boys themselves did not feel that they had slept poorly after having played violent games.

The results show that the autonomous nerve system, and thereby central physiological systems in the body, can be affected when you play violent games without your being aware of it. It is too early to draw conclusions about what the long-term significance of this sort of influence might be. What is important about this study is that the researchers have found a way, on the one hand, to study what happens physiologically when you play video or computer games and, on the other hand, to discern the effects of various types of games.

It is hoped that it will be possible to use the method to enhance our knowledge of what mechanisms could lie behind the association that has previously been suggested between violent games and aggressive behavior.

 

Getting the Solution Of Hair Loss

After six years of research scientists have succeeded in identifying a gene that is responsible for a rare hereditary form of hair loss known as Hypotrichosis simplex. The scientists are the first to identify a receptor that plays a role in hair growth. They now hope that their research findings will lead to new therapies that will work with various forms of hair loss.

Although Hypotrichosis simplex is very uncommon, it may prove critical in our search for an understand of the mechanisms of hair growth. The disease is inherited and affects both men and women. Sufferers generally begin to go bald during childhood. The process of hair loss (alopecia) then advances with age, especially around the scalp.

The cause of Hypotrichosis simplex in the form examined in this project is a genetic defect. It prevents certain receptor structures on the surface of hair follicle cells from being correctly formed. It has been found that when messengers from outside bind to these receptors they trigger a chain reaction in the cell interior which is apparently needed for the hair follicle to function normally. Such a receptor that plays a specific role in hair growth was previously unknown to scientists.
