In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed. At first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. The results show, wh...
The aim of the current study was twofold: (1) to validate the internal structure of the general English (GE) section of the university entrance examination for Ph.D applicants into the English programs at state universities in Iran (Ph.D. UEE), and (2) to examine the factor structure invariance of the Ph.D. UEE across two proficiency levels. Structural equation modeling (SEM) was used to analyz...

introduction: hyperlipidemia is a major cardiovascular risk factor. this survey has been performed to determine the prevalence of hyperlipidemia in the 17th zone of tehran. methods: 1573 individuals 25-64 aged were recruited from the inhabitants of the 17th zone of tehran through one stage cluster sampling. standard questionnaires were filled out for all of the participants. lipid profile was c...
balb/c mice are highly susceptible to infection with the protozoan parasite leishmania major. this susceptibility has been attributed in part to the expansion of th2 cells and production of their cytokines, il-4 and il-10 and down-regulation of th1 cytokine, inf-γ. the inability of susceptible hosts to mount the immune response necessary to activate macrophage and destroy the parasites can be d...
codon optimization, cloning and expression of the human leukemia inhibitory factor (hlif) in e. coli
background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentiation, control of stem cell pluripotency...
purpose: to assess hoffer correction factor in measurement of axial length (al) in eyes with phakic iol implants. methods: in this descriptive historical cohort study, axial length was measured by ultrasound (us) and iol master in both phakic and pseudophakic modes in 24 eyes of 14 patients with artisan intraocular lenses (iols) implanted for refractive purposes, hoffer’s suggested formula for ...
کشور ایران از جمله کشورهای خشک و نیمه خشک جهان است که تأمین آب در آن به یکی از مهم ترین دغدغه های حاضر تبدیل شده است. منابع آب قابل برداشت به دو گروه آب های سطحی و زیرزمینی تقسیم-بندی می شوند که در چرخه هیدرولوژیکی مولفه های جدا از هم نیستند. حوضه فیروزآباد یکی از دشت های مستعد استان فارس برای کشاورزی است که در سال های اخیر به خصوص در قسمت آب زیرزمینی با افت شدید سطح آب روبرو شده است. در این تح...
Extended Abstract Introduction and Objective: Medicinal plants have many applications in the treatment of humans, among which chamomile is one of the most valuable and widely used medicinal plants in the world. One of the most important breeding programs is the recognition of genetic diversity for the initial evaluation of plant masses. For this purpose, a study of genetic diversity and classi...
