introduction: the contraception has been practiced for over 4000 years and the prevalence of contraceptive use has increased worldwide.the existing methods of contraception are not perfect and their acceptability is limited by side effects and inconvenience.thus there is a real need for new methods of contraception to be developed. the effects of the follicular fluid on the pregnancy rate has b...

We propose a new model that introduces peer effects into existing utility models of perceived needs. This combination introduces obstacles to obtaining identification that differ both from standard consumer demand and from standard models of peer effects. These obstacles arise from required nonlinearities in utility, from features of standard consumption survey data, and from heterogeneity that...

this experiment was conducted to evaluate the effects of different commercial multi enzymes and nutrients levels of diets on performance and carcass traits of broilers. in this experiment 288 day old ross – 308 broilers (male and female) were used as (2*4) factors include: two levels of nutrients in diets (ross- 308 nutrients recommendation and 5% less than ross- 308 nutrients recommendation) a...

the effects of four corn hybrids, keynes540, keynes410, ksc260 and ksc400, were investigated on life table parameters of the beet armyworm in a growth chamber that was set at 25 ± 1 ºc, 65 ± 5% rh and 16:8 (l: d) photoperiod. the highest survivorship (lx) of adults were 0.77, 0.70, 0.62 and 0.58 on ksc260, keynes410, keynes540 and ksc400, respectively. the highest age-specific fecundity (mx) of...

Total Time. By day five, the average total time was 805 ms for 1HR and 682 ms for 2HS, reduced from 932 ms and 823 ms respectively on day one. Menu technique (p = .005) and day (p = .009) had significant effects on total time, but there was no interaction effect (F4,16 = 0.308, p = .869). Reaction Time. By day five, the average reaction time was 590 ms for 1HR and 533 ms for 2HS, reduced from 5...

effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...

wind power generation is variable and uncertain. in the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. in this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via monte carlo simulation ...
