Programmable Electronic Delay Device for Detonator

Delay devices are used to perform various roles like aiding in sequential release of payload, providing safety in flight/ trajectory, enabling self-destruction of ammunitions, allowing blast of the warhead after penetration in runway/bunker, etc. The delay time is introduced to cause a series of detonation events from the explosive charge, in order to achieve desired efficiency. Inspite of many improvements performed along the years, in search of precise delay compositions, it is noticed that the obtained accuracy in chemical delay compositions is of ±4%.The present work using microcontroller gives possible accuracy of upto ±1%.This paper discusses about programmable electronic delay device, timing accuracy of electronic delay device and its merits over chemical delay devices.Defence Science Journal, 2013, 63(3), pp.305-307, DOI:http://dx.doi.org/10.14429/dsj.63.288

Cold plasma processing: A review

The increase in the outbreaks reported due to consumption of infected produce has increased to a larger extent. Conventional technologies hamper the quality of food. To fulfill the need of an efficient cold processing method, researchers came up with a novel technology known as plasma technology. Two type's thermal and non-Thermal plasma exists. The non-Thermal or cold plasma technology is now the prime consideration in food processing industries viz. post-harvest, meat, packaging etc. Cold plasma plays an important role in decontamination of food and packaging materials from microorganisms, manufacturing of packaging materials, active packaging and retards browning reactions. Cold plasma withholds the ability to manufacture high quality fresh and processed food products

Study of the Concept of Green Buildings, Practices From the Past and Its Applicability Today

The paper aims at understanding green building and its interpretation over the years. The objectives are to study green building, to find similarities and differences between different terminologies. The methods used are to summarize understanding from literaturereview and case examples; to study the similarities between old cultural practices related to climate and new concepts; to understand way of living in the past, needs and today's Fast pace changing lifestyle
