INTRODUCTION Female genital mutilation/cutting (FGM/C) violates human rights. FGM/C women's sexuality is not well known and often it is neglected by gynecologists, urologists, and sexologists. In mutilated/cut women, some fundamental structures for orgasm have not been excised. AIM The aim of this report is to describe and analyze the results of four investigations on sexual functioning in di...

Despite dental implantation being a great success, one of the key issues facing it is a mismatch of mechanical properties between engineered and native biomaterials, which makes osseointegration and bone remodeling problematical. Functionally graded material (FGM) has been proposed as a potential upgrade to some conventional implant materials such as titanium for selection in prosthetic dentist...

This work investigates transient heat conduction in a functionally graded plate (FGM plate) subjected to gradual cooling/heating at its boundaries. The thermal properties of the FGM are assumed to be continuous and piecewise differentiable functions of the coordinate in the plate thickness direction. A linear ramp function describes the cooling/heating rates at the plate boundaries. A multi-lay...

A review on the recent development in the non-linear flutter and thermal buckling of an FGM panel under the combined effect of elevated temperature conditions and aerodynamic loading is investigated using a finite element model based on the thin plate theory and von Karman straindisplacement relations to account for moderately large deflection. It is found that the temperature increase has an a...

Abstract The Fairlie-Gumbel-Morgenstern (FGM) family has been investigated in detail for various continuous marginals such as Cauchy, normal, exponential, gamma, Weibull, lognormal and others. It has been a popular model for the bivariate distribution with mild dependence. However, bivariate FGM’s with continuous marginals on a bounded support discussed in the literature are only those with uni...

ÐA functionally graded composite is prepared and the spatial gradation of Young's modulus in the functionally graded material (FGM) is measured. Elastic modulus gradients occur over length scales suitable for experimental mechanics investigations using optical interferometry. Crack tip ®elds are mapped in the FGM under quasi-static loading conditions with cracks oriented perpendicular to the di...

تحلیل پایداری و مطالعه رفتار کمانش صفحات، همواره به عنوان یکی از مهم ترین موضوعات در تحلیل سازه¬ها مورد توجه بوده است. در این مقاله کمانش نامتقارن ورق های حلقوی ساخته شده از مواد تابعی روی یک محیط الاستیک، تحت فشار شعاعی یکنواخت و حرارت به طور تحلیلی مورد بررسی قرار گرفته است. با استفاده از نظریه¬ی کلاسیک و فرضیه¬ی غیرخطی ون-کارمن، معادله تعادل به دست آمده است. خواص ترمومکانیکی ورق به صورت تابع...

Analytical relations between the critical buckling load of a functionally graded material (FGM) Timoshenko beam and that of the corresponding homogeneous Euler–Bernoulli beam subjected to axial compressive load have been derived for clamped–clamped (C–C), simply supported–simply supported (S–S) and clamped–free (C–F) edges. However, no such relation is found for clamped–simply supported (C–S) b...

Traumatic Stress Studies (NKVTS) commissioned the Norwegian Knowledge Centre for the Health Services (NOKC) to conduct a systematic review about the consequences of female genital mutilation/cutting (FGM/C). The review would answer the question: What are the psychological, social and sexual consequences of FGM/C? Methods: We searched systematically for relevant literature in international scien...
