If there is a decline in mortality, it mainly younger age groups. As result, more and deaths are occurring older In advanced societies, therefore, people becoming “more equal the face of death”. A sharp increase such as that caused by Covid-19 pandemic, affects different groups population to degrees. It therefore relevant study change inequality life expectancy under conditions sudden shock. Th...
This article presents the exact solutions of the velocity and temperature fields for a steady fully developed magnetohydrodynamic flow of a viscous incompressible and electrically conducting fluid between two horizontal concentric cylinders. Our study focuses on the influence of the Hartmann number, Brinkman number, Péclet number and inner radius on the fluid temperature field, entropy generati...
abstract: colorado potato beetle (cpb), leptinotarsa decemlineata (say),is the most important insect pest of potato in iran. if local potato varieties vary in susceptibility to the pest, host plant resistance may provide management benefits to potato growers. a life table study was carried out to determine the relative suitability of four common potato varieties (agria, marfona, savalan and sat...
the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...
