in this paper, we consider an  i.e., multiple step-stress accelerated life testing (alt) experiment with unequal duration of time . it is assumed that the time to failure of a product follows rayleigh distribution with a log-linear relationship between stress and lifetime and also we assume a generalized khamis-higgins model for the effect of changing stress levels. taking into account that the...

Fusarium wilt of cotton, caused by F. oxysporum f sp.vasinfectum, was first recognized in Australia in 1993. The pathogen can be seed borne and it can also be dispersed in soil and crop residues attached to vehicles and machinery and carried in irrigation and flood water. Infection is favored by cool, wet spring conditions and shallow development of roots. The rapid increase in the distribution...

INCE 1974, FOLLOWING PUBLICATION of Schuh’s “The Macroeconomics of Agriculture,” much research effort has been devoted to determining whether and how monetary policy affects the farm sector. One of the more active areas of interest has been the question of whether changes in the money stock affect the farm! nonfarm product relative price ratio. The reason for this particular interest, as descri...

Rich in potential in human and natural resources Uttar Pradesh (UP) once appeared positioned to be the pace-setter for India's economic and social development. However, the growth rate of Uttar Pradesh has declined in the Eleventh Five Year Plan as against Bihar. The paper finds the causes of poverty and unemployment in Uttar Pradesh; it also analyse important socio-economic indicators of Uttar...

In this paper, we analyze the insect resistance management (IRM) plan put in place by the US Environmental Protection Agency (EPA) to delay the evolution of resistance to Bt corn in natural populations of the European corn borer, Ostrinia nubilalis Hübner. This IRM plan is the most impressive mandatory IRM system ever developed. It forms a coherent whole and includes mandatory refuges, actions ...

The technique of the processor farm has become very widely used for paral-lelising applications, often being mentioned without reference to any source. The goal of this work has been to put together a complete and rigorous understanding of what the technique can be used for and what is needed in order to arrive at an eeciently farmed application. This paper consists of these two parts. We have ...
