IIT-M study on air pollution

IIT-M study on air pollution

Indian Institute of Technology-Madras is studying the ambient air quality in the city under the `Emission Inventory and Source Apportionment study commissioned recently.

The study is focussed on the impact of vehicular emissions and industries on air quality. The 18-month-long study should be over by February next year, said a senior official of the Tamil Nadu Pollution Control Board. A similar study by the TNPCB in 2003 found that vehicular emissions were the major contributor to air pollution. The draft second Master Plan prepared by the Chennai Metropolitan Development Authority and made public on Wednesday refers to the 2003 study. It said the major contributors to Chennai air pollution load are vehicles (71.28 percent) and industry (19.7 percent).

The TNPCB study had also mapped areas where the amount of suspended particulate matter was the highest. It includes T. Nagar, parts of Saidapet, Choolaimedu, Vadapalani, Royapettah, Egmore, parts of Adyar, Teynampet, parts of Tondiarpet, Koyambedu, Purasawalkam, Mandaveli, Mylapore and George Town. In addition to the pollution caused by the vehicles, unpaved roads lead to collection of sand on the roadsides, causing dust to rise, the study said.

MMRDA Ready With Sops To Bypass IIT Roadblock

The Mumbai Metropolitan Region Development Authority (MMRDA) has devised a compromise formula to give impetus to the 10.3-km, six-lane Jogeshwari-Vikhroli Link Road (JVLR) project. Work on Section 2 of the project, on a 3-km stretch between Indian Institute of Technology (IIT), Powai, and Kanjurmarg, had been moving at a snail’s pace because of the IIT’s reluctance to release 10,000 sq-mt land. The MMRDA has now proposed special compensation for the IIT to take the project ahead. JVLR is one of two road overbridges being constructed under the World Bank-aided Mumbai Urban Transport Project (MUTP). The MMRDA wants the IIT

IIT develops technology to produce stealth aircraft

IIT develops technology to produce stealth aircraft Materials scientists at the Indian Institute of Technology in Roorkee (IIT-R) have developed microwave absorbing nanocomposite coatings that could make aircraft almost invisible to radar. The technology for building invisible, or stealth aircraft, is a closely guarded secret of developed countries and a handful of laboratories in India are doing research in this area. Radars that emit pulses of microwave radiation identify flying aircraft by detecting the radiation reflected by the aircrafts metallic body. The nanocomposite coatings developed by Rahul Sharma, R.C. Agarwala and Vijaya Agarwala at IIT-R absorb most of the incident radiation and reflect

Tutor Claiming To Be Iitian Turns Out To Be Fraud

A PRIVATE tutor in Subhanpura, Devesh Bharadwaj, who claimed to be a gold medallist from IIT Delhi, was found to be lying about his credentials.

The Saga of Shopping Malls and Connecting Roads

The Saga of Shopping Malls and Connecting Roads Most shopping malls have a sale return policy within a few days. I was rudely shocked to find that the D-Mart at Powai was enticing unsuspecting customers to buy, without telling them that some items will not have that usual facility! I was attracted to buy one non-stick tawa on sale. However, when I went to return it within 24 hours, I was shown a small placard hidden behind some large pressure cookers. It did state that there was no sale return or exchange on non-stick cookware, but how are the buyers to
