abstract background: the aim of this study was to compare the effects of the second- and third-generation oral contraceptives on women’s reproductive sexual function. materials and methods: this randomized, double-blind, placebo-controlled clinical trial was conducted on 82 married women of reproductive age in tehran. samples were randomized into the groups receiving second- and third-generatio...

this paper aims at studying a trigeneration system, based on an internal combustion engine and a steam ejector refrigeration system. the designed cycle is to generate cooling and heating energies, and supply power simultaneously. the cycle is studied from thermodynamics point of view and for this purpose, the first law of thermodynamics is applied to all components of the cycle. the efficiency ...

background most women taking combined oral contraceptives (cocs) are satisfied with their contraceptive method. however, one of the most common reasons reported for discontinuation of combined oral contraceptives (cocs) is mood deterioration. objectives this study aimed to compare effects of the second and third generation oral contraceptive pills on the mood of reproductive women. materials an...

In this article we perform a combined analysis of low energy precision constraints and LHC searches for leptoquarks which couple to first generation fermions. Considering all ten leptoquark representations, five scalar vector ones, study at the frontier from $K\to\pi\nu\nu$, $K\to\pi e^+e^-$, $K^0-\bar K^0$ $D^0-\bar D^0$ mixing, as well experiments searching parity violation (APV QWEAK). We in...

Electricity generation in thermal power plants as the largest producer of electricity in Iran is associated with greenhouse gas emissions. In this paper, using the Malmquist-Luenberger method, green productivity, and efficiency changes are measured for 31 thermal power plants (including 12 steam power plants, 13 gas power plants, and six combined cycle power plants) during 2009-2016. The result...
