Safety critical systems are the systems which defines the safety and monitors the system performance based on some safety criterions. A system health management (SHM) system monitors the safety critical system while it is in operation, and thus is able to detect faults, as soon as they occur. In this paper we propose an approach to determine the system health using artificial neural network. Unmanned Aerial Vehicle is used as a case study to demonstrate the SHM approach using ANN.

It has been found that the conventional software engineering models such as for example Waterfall model, Prototyping, Incremental, Spiral, Rational Unified process (RUP) and Extreme programming (XP) cannot be used directly or not applicable for the development of web based systems (Kumar and Sangwan 2011). This is because Web applications have unique characteristics that make Web development different and more difficult than traditional software development. In this paper, the reasons of why software development methodologies failed in developing web based systems will be shown.

Agriculture sector plays a pivotal role in the economic development of the country. In spite of this, rural youth faced challenges regarding livelihood. As a result, they often prefer to migrate to urban areas to take up low paying jobs. The present study was focused on the determinants of attitude of rural youth towards agriculture as a means of livelihood. The study was conducted in four villages of Uttarakhand. Data was collected from 115 rural youth through interview schedule.

Farming community is at a crucial state of transformation both in farming activities as well as in their social life. Farm power and material possession show a clear indication of such change. Nuclear family concept is evident. Draught animals raring are also going to be diminished. Irrigation and pest management equipment are found plenty. Bullock cart is totally extinct instead they are using Tricycle Van and Tractor drawn Trolley as means of conveyance of farm articles. Possession of Mobile Telephone, Bicycle, Television are most common.

The allelopathic effect of medicinal leaf extracts of Ocimum sanctum L., Calotropis procera(Ait.) Ait.f and Astragalus tribuloides Delile on the radical length of mungbean (Vigna radiata L. Wilczek) in Vitro conditions. The results indicated that different extracts such as alcoholic, aqueous acidic and alkaline extract of Ocimum sanctum L., Calotropis procera(Ait.) Ait.f and Astragalus tribuloides Delile showed different radical length of mungbean in Vitro conditions. Alcoholic extract of Ocimum sanctum L. showed highest radical effect in comparison of other extracts.

Bacillus subtillis Ch13 is an active ammonifying bacteria who plays a main role in nitrogen cycling. But, it has multifunctional properties that, beside the stimulating, has the fungicidal effect on plants, too. It is a base of a microbiological product Exstrasol  which is used for examination. Modern tobacco production follows the ecological principles of sustainable agricultural production and supports the use of environment-friendly products, especially the use of biological products in the control of tobacco pathogens.

Byssinosis is a respiratory disease caused by inhalation of cotton dust for prolonged period of time. This is most frequently occurs in the cotton mill women workers. The word byssinosis is derived from Latin which means fine, soft, white fibers. Byssinosis is characterized by cough, wheeze, and chest tightness on the 1st day of work after returning from rest. 
Aim: The present study taken to evaluate the lung function of cotton mill women workers who were working for past 5 years in Coimbatore district. 

In India about 2.40 million (1.93 ‐3.04 million) people are living with HIV and AIDS. India is the second largest population living with HIV and AIDS. Among the four high prevalent states of India, Andhra Pradesh has the highest number of HIV patients in the country. It accounts for 20 per cent of AIDS patients (5 lakh of the 24 lakh). Guntur is one of the highly HIV burdened district in Andhra Pradesh, having more than 70,000 people living with HIV in the district alone.

Field experiments were conducted during Kharif 2007 and 2008 in sandy clay loam soil to study the effect of organic sources and urea on N transformation and yield of rice. The treatments consisted of addition of different organics viz., composted coir pith (CCP), green manures (GM), sugarcane trash compost ( STC), vermicompost (VC), poultry manure (PM) and FYM applied at 100% RDN and combination of above organics @50% N and urea@50%N besides 100% RDN as urea and control.

The annual reproductive cycle of the crab, Barytelphusa guerini was studied during the period January 2015 to December 2015 by measuring monthly histological variations. Histological observations of the monthly gonads revealed that the ripening of the gonads started in the preparatory period of the reproductive cycle i.e. (January to April) or it may be extended upto the month of May. By that time, the gonads of the most individuals attained maturity and spawning began in the months of June and July.
