recently the stepped spillways have been used as an appropriate solution for energy dissipation. in the present study, siahbisheh dam spillway is simulated by using computational fluid dynamic (cfd), in which the mixture method and reynolds stresses model (rsm) turbulence model is used. in the first modeling series the over all steppes slope is constant. the number of the steps is increased to ...

BACKGROUND Depression in women is one of the commonest problems encountered in primary care. We aimed to compare the effectiveness of a stepped-care programme with usual care in primary-care management of depression in low-income women in Santiago, Chile. METHODS In a randomised controlled trial, in three primary-care clinics in Chile, 240 adult female primary-care patients with major depress...

This paper describes the formulation and performance of a nonhydrostatic model featuring a unique variable stepped topography representation capable of capturing steep topographical slopes, while at the same time accurately representing subtle topography variations. The proposed enstrophy conserving formulation and the quasi-compressible closure cast on a multiply nested rotated spherical grid ...

Simulations of bifurcated three-dimensional laminar forced convection in horizontal duct with plane symmetric sudden expansion are presented to illustrate the effects of flow bifurcations on temperature and heat transfer distributions. The stable bifurcated flow that develops in this symmetric geometry leads to non-symmetric temperature and heat transfer distributions in the transverse directio...

BACKGROUND A short-term study was undertaken with an objective to demonstrate the therapeutic benefit resulting from the use of Metronidazole sponges combined with and without mechanical debridement to mechanical treatment alone in the treatment of periodontal pockets in chronic periodontitis. MATERIALS AND METHODS The study compared the plaque index, gingival index, sulcus bleeding index and...

BACKGROUND AND OBJECTIVE The existing literature is inconsistent regarding whether there is any additional effect of povidone-iodine (PVP-iodine) as an adjunctive to scaling and root planing, and, if there is an effect, what its size is. Therefore, the aim of this study was to assess the additional effect of PVP-iodine as an adjunct to scaling and root planing compared with water, saline or no ...
