Tuberculosis is an endemic disease of the poverty ridden, undernourished and over populated countries of the world. It is also a systemic disease that is extremely dependent on the physiology of the system it invades and thus varies signifi cantly from person to person. New developments in the treatment of this d isease have rarely percolated down to the larger sections of the under privileged in our societies. The need for highly active, long acting, yet less expensive drugs against Multi-Drug Resistant (MDR) Mycobacterium tuberculosis still exists.

The conventional waste water treatment technologies are based on processes like Activated sludge process, Extended aeration, Submerged aerobic fixed film reactor, Trickling filter or Rotating Biological Contactor. However, in the recent years there has been a shift towards adoption of Sequential batch reactor (SBR) and Moving bed biological reactor (MBBR). This paper reviews various MBBR models available in the Indian market for the treatment of municipal and industrial wastewater and their effect on reactor volume and media quantity.

Sehgal, M, Suresh R, Sharma VP, and Gautam SK
The air was monitored for two consecutive periods, in the dry and the rainy seasons (2009–2010) at 40 petroleum-filling stations in the Indian capital, Delhi, to assess variations in carbon monoxide, nitrogen dioxide, PM10, PM2.5, benzene, toluene and xylene content. PM10 and PM2.5 concentrations exceeded the national ambient air quality standards at all the monitoring locations with maximum values of 1105 and 625 micro gm_3, respectively, in the dry season.
