Anna University to extend 12 M.E. programmes
Staff Reporter
To industry employees from current academic year onwards
On main campus as well as six constituent colleges
TIRUCHI: Anna University – Tiruchi has decided to extend the 12 M.E. programmes it has been offering for about 600 teachers in affiliated engineering colleges and polytechnic colleges over the past couple of years to industry employees from the current academic year.
The programmes offered under modular-based credit banking scheme will be conducted on the main campus as well as the six constituent colleges at Panrutti, Pattukottai, Thirukuvalai, Ariyalur, Dindigul and Ramanathapuram.
The university is in touch with major industries in Tiruchi region, including BHEL and Ordnance Factory, Golden Rock Railway Workshop and Cethar Vessels.
“We have requested the industries to depute experts for handling the programmes,” the Vice-Chancellor V. Ramachandran told presspersons on Friday.
He saw in the initiative a mechanism for fortifying industry-institution interaction.
M.E. applicants with a first class in B.E. must have worked in the industry for a minimum of one year.
Enrolment
The university expects enrolment of at least 60 candidates on the main campus. The M.E. programmes are being offered in Structural Engineering, Thermal Engineering, CAD/CAM, Manufacturing Engineering, Power Systems Engineering, Embedded System Technologies, Communication Systems, VLSI Design, Computer Science and Engineering, Software Engineering, Pervasive Computing Technologies, and Systems Engineering and Operations Research.
The first batch of college teachers enrolled under the modular-based credit banking scheme will complete M.E. during July next year.
Classes are being held during weekends and vacations without disturbing academic schedule of colleges, the Vice-Chancellor said.
In the coming years, Dr. Ramachandran expected experienced polytechnic teachers who are currently pursuing the M.E. programme of three-year duration to take up teaching positions in engineering colleges.
Anna University Trichy came into existence in January 2007 upon trifurcation of Anna University into three universities, namely, Anna University Chennai, Anna University Trichy, and Anna University Coimbatore. The Anna University, Trichy was formerly known as School of Engineering and Technology or the Bharathidasan Institute of Technology. It was initially a part of the Bharathidasan University. The university is an accredited university with powers to grant affiliations to colleges and universities conducting graduate and post graduate, including diploma course, and is so recognized by the UGC.

practical in reality? In spite of years of scientific research, no-one really knows how much damage human beings are doing to their environment. We know that they are responsible for many problems ranging from global warming to ozone depletion, and there is no doubt that they have a devastating effect on animal and plant life on Earth.
About 50,000 animal and plant species are becoming extinct every year. All species depend in some way on one another for survival. If you remove one species from this complex web of interrelationships, we have little idea of the repercussions on the ecosystem in general.
What makes things more complicated is the fact that unlike global warming - which, if the political will was there, could be reduced by cutting gas emissions - preserving bio¬diversity remains a difficult dilemma.
There are also questions about whether sustainable management is practical as far as protecting areas of great bio-diversity such as the world's tropical forests are concerned. In theory, the principle should be the same as with elephants; i.e. to cut a number of trees, but not so many as to completely destroy the forest.
Sustainable management of trees requires controls on the number of trees which are cut down as well as investment in replacing them. Most tropical forests exist in poor countries which depend on logging to make money. For most loggers in these countries, making money means cutting down as many trees as possible in the shortest time. The prices of trees remains stable, varying by 4-5% annually, whereas interest rates in most developing countries can create 15% or more in returns. It therefore makes little sense, and certainly no economic sense, to delay tree-felling.
One solution could be to insist that wood comes from sustainably managed forests. In theory, consumers would buy only this wood and force logging companies to go "green" or else out of business. Unfortunately, unrestricted logging is more profitable than wood from sustainably managed forests which would cost up to 5 times more to control. Consumers would not be prepared to pay the extra sum just to protect the environment.
The sad fact is that there is no practical solution to protecting vegetation and wildlife of tropical forests in the future. It is estimated that these forests contain anything from 50 to 90 per cent of all animals and plant species on Earth. In one study of a 5km square area of rain forest in Peru, for example, scientists counted 1,300 species of butterfly and 600 species of bird. In the entire USA only 400 species of butterfly and 700 species of bird have been recorded. Sustainable management represents a gigantic experiment. If this doesn't work, we can't move to another planet to escape. It's a case of one planet, one experiment!
A. Complete the following statements choosing from one of the given alternatives.(6 x 1
= 6)
1. The extent of the damage being inflicted on our environment...
a. can be estimated by years of scientific research.
b. is being calculated by scientific research exactly.
c. is impossible to assess despite years of scientific research.
d. is, thanks to years of scientific research, on the decrease.
3
2. The term 'sustainable management' means using plants and animals for our own benefit, but..
a. assuring none are left alive to guarantee the survival of the species.
b. making sure that enough are left alive to guarantee the survival of the species.
c. take care of the survival of the species.
d. make certain they are not all used up.
3. If a particular species becomes extinct...
a. we know exactly what effect it will have on our ecosystem.
b. we have little knowledge about its effects on our ecosystem.
c. it has no relationship with other species in our ecosystem.
d. its removal from the ecosystem will have no repercussions.
4. Preserving bio-diversity in our ecosystem...
a. is less complicated than reducing global warming.
b. can be resolved politically, just like global warming.
c. is not simply a political dilemma to be resolved like global warming.
d. can be resolved only by cutting gas emissions.
5. Applying the theory of sustainable management to the protection of tropical forests...
a. is creating worries and doubts in people's minds, especially as regards its feasibility.
b. means you can cut as many trees as you want without destroying the forest.
c. is a practical and economical way of protecting them.
d. is exactly the same as that applied to protecting elephants.
6. It is vital to protect the wildlife of tropical forests...
a. because there are over 700 species of bird recorded in the whole of the USA.
b. because sustainable management offers a real, practical solution.
c. because scientists couldn't find as many species of butterfly or bird in the Peruvian rainforests.
d. because of the wide variety and quantity of species of wildlife that inhabit them.
B. Choose the option that best represents the meaning of the following words as they are sued in the text.(6 x 1 = 6)

b. Tropical forests house less than half of the plant and animal species on Earth.
c. Human beings are not really responsible for the damage to the environment.
d. Wood from sustainably managed forests is cheaper than wood from forests where unrestricted logging is permitted.

iii. It is a known fact robots have many advantages over human beings.
iv. Taking into account all these factors, it should be remembered that robots owe their existence, to human beings.
v. However, it is also true that humans can do many things that robots can't.
vi. Even if the robots are able to move, they can do, only in a very limited way.
vii. For example, humans can carry out a task without having to be told exactly how to do it; they don't have to be programmed.
