Functionally graded metal-ceramic composite was fabricated by pressure-less sintering. The pure metallic component (Ti) and the pure ceramic component (HA) were located at the ends of a cylindrical specimen. Titanium and-Hydroxyapatite were utilized as a metallic and ceramic layer. The target sample thickness was 6 mm with radius cylindrical 20 mm. The sample was made from the cylindrical type ...
Potential stressors of wildlife living in captivity, such as artificial living conditions and frequent human contact, may lead to a higher occurrence of disease and reduced reproductive function. One successful method used by wildlife managers to improve general well-being is the provision of environmental enrichment, which is the practice of providing animals under managed care with environmen...
In our recent systematic review in Obstetrics and Gynecology International of the association between FGM/C and obstetric harm we concluded that FGM/C significantly increases the risk of delivery complications. The findings were based on unadjusted effect estimates from both prospective and retrospective studies. To accommodate requests by critics, we aimed to validate these results through add...
Some male spiders exhibit female genital mutilation behaviour (FGM) by removing the female genital appendage (scape) to control the mating frequency of females. Female spiders have two, i.e. right and left, genital openings connected with separate spermathecae into which males transfer sperm successively using one pedipalp (secondary genitalia) at a time. Thus, males must complete at least two ...
Recently, metal-selective fluorescent chemosensors have attracted intense attention for their simple and real-time tracking of metal ions in environmental samples. However, most of the existing fluorescent sensors are one-off sensors and thus suffer from large amount of reagent consumption, significant experimental cost and raising the risk of environmental pollution. In this paper, we develope...
– We study quantum effects of light propagation through an extended absorbing system of two-level atoms placed within a frequency gap medium (FGM). Apart from ordinary solitons and single-particle impurity band states, the many-particle spectrum of the system is shown to contain massive pairs of confined gap excitations and their bound complexes—gap solitons. Quantum gap solitons propagate with...
In this article, vibration characteristics and the parametric instability of functionally graded material (FGM) plates with cyclic loading in a hygrothermal field are discussed. The plate element is modeled in a finite element by applying the third-order shear deformation hypothesis. The mathematical formulation of the FGM plate is made with two material constituents by applying the power rule ...
the effect of axial deformation of shell particles on the dynamic instability (flutter) of cantilevered cylindrical shells made of functionally graded materials (fgm) under an end axial follower force is addressed. to this end, at first, results for free vibration of fgm cylindrical shells were verified with previous outcomes and they were in very good agreement. then, the effect of axial defor...
در این پایان نامه یک کره پوشش دار با پوشش fgm در محیط بی نهایت و ایزوتروپ مفروض است. با استفاده از توابع پتانسیل لامه و بسط توابع ویژه مساله انتشار امواج پیرامون کره پوشش دار با پوشش fgm مورد مطالعه قرار می گیرد. رفتار مصالح الاستیک خطی و تغییر شکل ها در محدوده تغییر شکل های کوچک قرار دارد. عمده مسائل بررسی شده به کره با پوشش غیر fgm پرداخته اند. همچنین مطالعات انجام شده در زمینه کره با پوشش fg...
