The procedure outlined describes an extremely sensitive and accurate method for the determination of mercury down to 1.0 ppb in solution. This procedure has been applied to nickel and cobalt metal as well as rock samples and soil samples containing organic materials.

Bihar is a predominantly agricultural State with 86 per cent of her population depending upon agriculture. In my study of the National Income of Bihar published in the Indian Journal of Economics, July 1951, I had estimated the gross agricultural income of Bihar for the year 1846-47 at Rs. 230 crores, basing myself on the statistics published in the Season and Crop Report, and at Rs. 272 crores when based on the statistics contained in the Crop Survey Report.

The S.W. monsoon or summer monsoon is a major event in the agricultural life of India, which has been widely studied. The chief characteristic of the pressure distribution over India during the monsoon is the trough of low which extends from the the S.E. Punjab to the head of the Bay and the concomitant high pressure belt in the Indian Ocean.

The outstanding feature of Indian weather in the second half of April and the first week of May of the year was the extremely high temperatures over a large part of Northern India.

Earlier researches have shown that forecasts of crop acreage and yields can be made on the basis of weather factors. Where adequate data exist such forecasts may be more accurate than those arrived at by the subjective methods used in the official forecasts of most countries.

On Monday the 15th January 1934 Calcutta experienced an earthquake shock of fair intensity which lasted for over three minutes. News from the country was available only next morning, showing that Patna, Monghyr and Jamalpur had suffered severely. News from the most affected region arrived only two or three days later.

Most organisms have a built-in clock that regulates their biological functions on a roughly 12-hour schedule. Though researchers have identified genes that follow the circadian clock, what gears the clock remained unknown, until now.

Nirbhai Singh, an undertrial, wrote a letter from Ludhiana’s Central Jail five years ago and stirred industry and government into action. Addressed to the High Court of Punjab and Haryana, the letter expressed concern over pollution in the city. The court then began to look into the state of environment, in particular the Buddha Nallah. The government took up the matter in earnest and as a result, Ludhiana now has a Rs 650 crore remedial action plan. It aims to treat all its wastewater by March 2012.

Bilirubin, responsible for the yellowish tinge in the skin, eyes and nails of jaundice patients, has for the first time been identified in plants.
