Abstract

Milk and dairy products have significant importance to human nutrition during different stages of life but they can also act as vehicle for spread of various milk-borne diseases. India is a developing country and faces greater challenges m this aspect due to poor knowledge of processing or storage of dairy products which is responsible for transmission of a number of milk-borne zoonotic diseases viz., tuberculosis, brucellosis, salmonellosis, campylobacteriosis etc. These diseases pose severe threat to human life and some of them could be fatal as well. There is a need to detect these pathogens which can transmit due to insufficient pasteurization of milk or milk products or through post-pasteurization contamination, m order to successfully avoid transmission of these diseases. Proper pasteurization, surveillance and pubHc awareness about milk borne zoonotic diseases can contribute significantly m reducing incidence of these diseases. This review highlights the important milk borne diseases and their remedy for control and prevention of these diseases.

Abstract

An Infrared Free Electron Laser (IR-FEL) designed to operate in the 12.5–50 μm wavelength band is presently in an advanced stage of commissioning at the Raja Ramanna Centre for Advanced Technology (RRCAT), Indore. Here we report results from first experiments on the IR-FEL after installation of its optical cavity, which has resulted in a power output that is ~105 times the expected spontaneous emission power for the beam parameters used in the experiment. The estimated out-coupled peak micro-pulse power during these experiments is ~2 kW. This is the first observed signature of lasing in the IR-FEL, and the first reported lasing in a FEL in India. This communication discusses the development of the IR-FEL, the recent experimental results, and the ongoing efforts to further increase the IR power to the design peak out-coupled power of 2 MW.
