Solving multicommodity capacitated network design problems is a hard task that requires the use of several strategies like relaxing some constraints and strengthening the model with valid inequalities. In this paper, we compare three sets of inequalities that have been widely used in this context: Benders, metric and cutset inequalities. We show that Benders inequalities associated to extreme r...

The aim of this study was to gather knowledge regarding the conception of young people as for HIV/AIDS and the use of condoms in sexual intercourse. Survey conducted in May, 2012, at a public school in the city of João Pessoa, Paraíba, with eleven young people of both sexes. The chosen technique of investigation was a semi-structured interview. Empirical data were organized according to categor...

this study aims to investigate the effect of xylopia aethiopica on the sexual behavior of adult male rats. fort eight adult male wistar rats were used for the study. they were randomly divided into four groups of 6 animals each: group 1 was control, while groups 2, 3 and 4 were test groups treated daily with 0.5, 2 and 10 mg/kg body weight respectively of hydro-methanolic fruit extract of xylop...

conclusions the results showed that having an addicted husband could strongly affect some sexual domains in women. it could change the pattern of desire and motivation for sexual contact in females and alter their attitude toward the sexual relationship, thereby causing disturbances in the females’ normal sexual function. results according to the results, the frequency of hypoactive sexual desi...

background: female sexual dysfunction (fsd) defines as any disorder in the process of sexual contact including 6 main domains, desire, arousal, lubrication,  orgasm,  orgasm  satisfaction  and  pain. this study was conducted to evaluate prevalence of sexual dysfunction disorder in women with migraine headache and also find the associated factors related to migraine characteristics. methods: a t...

abstract background: women’s sexual self‑esteem is one of the most important factors that affect women’s sexual satisfaction and their sexual anxiety. various aspects of sexual life are blended with the entire personality. determining the relationship between personality traits and self‑concept aspects such as sexual self‑esteem leads to better understanding of sexual behavior in people with di...

abstract background: the world health organization emphasizes on integration of sexual health into primary health care services, educating people and health care workers about sexuality, and promoting optimal sexual health. despite the high prevalence of sexual problems, these problems are poorly managed in primary health care services. this study was conducted to evaluate the efficacy and feas...

Classical solutions of nonlinear partial differential equations are approximated in the paper by solutions of quasilinear systems of difference equations. Sufficient conditions for the convergence of the method are given. The proof of the stability of the difference problem is based on a comparison method. This new approach to the numerical solving of nonlinear equations is generated by a linea...

1.1. Hardy-Sobolev-Maz’ya inequalities. Hardy inequalities and Sobolev inequalities bound the size of a function, measured by a (possibly weighted) L norm, in terms of its smoothness, measured by an integral of its gradient. Maz’ya [22] proved that for functions on the half-space R+ = {x ∈ R : xN > 0}, N ≥ 3, which vanish on the boundary, the sharp version of the Hardy inequality can be combine...
