This research scrutinizes the impact of plane strain on optical characteristics Indium Phosphide (InP) employing first-principles methodology, grounded Density Functional Theory (DFT). The findings suggest that peaks spectral response curves dielectric function, refractive index, extinction coefficient, absorption and reflection coefficient InP, when subjected to tension strain, shift towards l...
گازوئیل که یکی از محصولات عمده نفت خام است، منبع عمده آلودگی محیط زیست به شمار می رود و می تواند اثرات خطرناک زیستی بر محیط اطراف اعمال کند. یکی از روش های بازیابی این مناطق آلوده و وارد نمودن آنها در چرخه تولید محصول سالم، حذف آلاینده ها با روش های زیستی است که از این میان روش تجزیه زیستی با توجه به استفاده از توان طبیعی و پتانسیل های نهفته طبیعت و هزینه پایین بیشتر مورد توجه بوده است. در ای...
Individual, naturally occurring Phlebotomus mongolensis and Phlebotomus caucasicus from Iran were screened for infections with the maternally inherited intracellular Rickettsia-like bacterium Wolbachia pipientis via targeting a major surface protein gene (wsp). The main objective of this study was to determine if W. pipientis could be detected in these species. The sandflies were screened using...
The occurrence of large earthquakes in stable continental interiors challenges the applicability of the classical steady state “seismic cycle” model to such regions. Here we shed new light onto this issue using as a case study the cluster of large reverse faulting earthquakes that occurred in Fennoscandia at 11–9 ka, triggered by the removal of the ice load during the final phase of regional de...
Serratia marcescens is an important cause of opportunistic human infections. Many, but not all, strains produce prodigiosin, a secondary metabolic, red-pigment antibiotic, the biosynthesis of which is directed by the pig gene cluster. Quorum sensing (QS) involves the production and detection of chemical signal molecules as a means to regulate gene expression in response to population cell densi...
This paper presents a new model of equivalent modulus derived from the Repeated Load CBR (RL-CBR) test without strain gauge. This model is an updated version of Araya et al. model (2011), the update consists of using the vertical strain as weighting factor instead of vertical displacement in the mean vertical and horizontal stresses calculation. The accuracy of equivalent modulus was improved b...
گسترش فعالیتهای صنعتی، ازدیاد جمعیت و دخالت بشر در محیط زیست میزان ورود فاضلابهای صنعتی، شهری و کشاورزی را به اکوسیستم های دریایی افزایش داده است. این فاضلابها حاوی آلاینده هایی از قبیل سموم کشاورزی، ازت، فسفر و فلزات سنگین می باشند. فلزات سنگین به علت پایداری و تجزیه ناپذیر بودن، قابلیت ورود به زنجیره های غذایی و تجمع زیستی در آبزیان از مهمترین آلاینده های دریایی محسوب می شوند. راهکارهای بسیار...
In this study, a multidimensional strain estimation method using biplane ultrasound is presented to assess local relative deformation (i.e., local strain) in three orthogonal directions in skeletal muscles during induced and voluntary contractions. The method was tested in the musculus biceps brachii of five healthy subjects for three different types of muscle contraction: 1) excitation of the ...

Photobacterium profundum is a cosmopolitan marine bacterium capable of growth at low temperature and high hydrostatic pressure. Multiple strains of P. profundum have been isolated from different depths of the ocean and display remarkable differences in their physiological responses to pressure. The genome sequence of the deep-sea piezopsychrophilic strain Photobacterium profundum SS9 has provid...
