Use of composites for a range of structural application in aircrafts, space-crafts, automobiles, etc., has widely spread in the last few years. Other than weight reduction, cut-outs provide pathways to link different aircraft parts. In this paper, an experimental investigation was conducted to study the effect of a cut-out on the tensile strength of the fiber glass/ epoxy composite plate. Geome...
The spread of the new Corona virus, known as COVID-19, has raised concerns and problems for many countries, and its out-of-China exposure is worryingly increasing. This trend is increasing in our country as well and has reached a critical point in some of the infected cities. This article attempts to provide appropriate strategies for controlling the virus for Iran based on the East Asia countr...
Modeling and Analysis of the Spread of an Infectious Disease Cholera with Environmental Fluctuations
A nonlinear delayed mathematical model with immigration for the spread of an infectious disease cholera with carriers in the environment is proposed and analyzed. It is assumed that all susceptible are affected by carrier population density. The carrier population density is assumed to follow the logistic model and grows due to conducive human population density related factors. The model is an...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
AIM We investigated differences of metastatic spread of normal proteinase-activated receptor-2 (Par2+/+) melanoma B16 in Par2-/- (knock-out) animals compared to C57Bl6 mice. MATERIALS AND METHODS Nine knock-out mice B6.Cg-F2rl1tm1Mslb/J (Par2-/-) and nine C57Bl6/J controls were subcutaneously inoculated with B16 melanoma tissue cells. Twelve days after inoculation, all primary tumors were rem...
Introdution: Today, the Advantages of radiation therapy by charged particles is indicated for the treatment of cancerous. During the passing of proton beam in the body tissues, secondary particles produce, which penetrate to the body healthy tissues and cause damage. The aim of this research was calculating the Spread out Bragg Peak for covering the breast cancer and investigating arrived dose ...
Despite decades of research across multiple disciplines, the early history of horse domestication remains poorly understood. On the basis of current evidence from archaeology, mitochondrial DNA, and Y-chromosomal sequencing, a number of different domestication scenarios have been proposed, ranging from the spread of domestic horses out of a restricted primary area of domestication to the domest...
Doctors use many tests to diagnose cancer and find out if it has spread from the lung. Some tests may also determine which treatments may be the most effective. A biopsy is the only way to make a definitive diagnosis of lung cancer. Imaging tests may be used to find out whether the cancer has spread, but they can never be used alone to diagnose lung cancer. This list describes options for diagn...
