We propose a series of methods and models in order to explore the Global Burden of Disease Study and the provided healthy life expectancy (HALE) estimates from the World Health Organization (WHO) based on the mortality μx of a population provided in a classical life table and a mortality diagram. Our estimates are compared with the HALE estimates for the World territories and the WHO regions al...

habrobracon hebetor say (hymenoptera: braconidae) as an ectoparasitoid of larval stage of lepidopterous pests is widely used in biological control programs. in the present research, the effect of field recommended doses of imidacloprid, indoxacarb and deltamethrin were studied on life table parameters of h. hebetor in pupal stage treatment. one hundred, two-day-old pupae were treated with 1 mic...

reproductive performance and life expectancy of the two-spotted spider mite (tssm), tetranychus urticae koch were determined on seven eggplant cultivars (isfahan, dezful, shend-abad, neishabour, bandar-abbas, jahrom and borazjan) at 25 ± 1°c, 60 ± 5% r.h. and a photoperiod of 16:8 (l:d) hours. the results revealed that the tssm gross hatch rate varied from 59% on bandar-abbas to 83% on dezful. ...

Background and aims: Life expectancy is one of the most important indicators of health and well-being of a society. Since it is claimed that in Aran-Bidgol region, center of Iran, life expectancy is higher than the average of the country, this study was designed. Methods: During a cross-sectional study, population and mortality data of Kashan University o...
