conclusions the majority of iranian women had neutral attitudes towards menopause, which may be evidence of poor knowledge about menopause. therefore, it is suggested that appropriate educational programs be developed and implemented by policymakers in order to increase knowledge and raise awareness among women about menopause. results out of the 21 selected documents, 11 studies were eligible ...

introduction: the aim of the present research was to conduct a meta-analysis on the effectiveness of play therapy studies on behavioral disorders in children. method: the method of this study was meta-analysis. twenty two studies from throughout iran (1996 to 2012) including 637 participants were used in this meta-analysis. data was analyzed using standardized mean difference effect size method...

Focusing beyond the acoustic diffraction limit has always been expected, especially in imaging and ultrasonic therapy. Manipulating waves offers an alternative application potential high-resolution medical ultrasound diagnosis treatment. Here, a two-dimensional circular meta-lens is presented, with sub-wavelength Helmholtz resonator array to implement super-diffraction focusing. The proposed co...

We present a detailed overview of the physics two-color soliton molecules in nonlinear waveguides, i.e. bound states localized optical pulses which are held together due to an incoherent interaction mechanism. The mutual confinement, or trapping, subpulses, leads stable propagation pulse compound, is enabled by Kerr effect. Special attention paid description binding mechanism terms attractive p...

hub covering problem (hlp) is a very popular areas of research for its wide ranges of applications in different service or manufacturing industries. this paper considers a bi-objective hub covering location problem with congestion. the objectives minimize the total transportation cost and the total waiting time for all hobs, respectively. the resulted multi-objective decision-making problem is ...

1. Introduction The presence of organic part in the new class of hybrid solids imparts an important chemical versatility to these materials compared to "classical" solids. The architecture of Metal Organic Frameworks (MOF) may lead to open structures with 1D (chains), 2D (layers) or 3D dimensionality developing very large surface areas (above 1000 m 2 /g) [1]. Some MOFs possess a structural ori...

Background Mendelian randomization studies perform instrumental variable (IV) analysis using genetic IVs. Results of individual Mendelian randomization studies can be pooled through meta-analysis. We explored how different variance estimators influence the meta-analysed IV estimate. Methods Two versions of the delta method (IV before or after pooling), four bootstrap estimators, a jack-knife ...
