The CERCHAR abrasivity test is very popular for determination of rock abrasivity. An accurate estimation of the CERCHAR abrasivity index (CAI) is useful for excavation operation costs. This paper presents a model to calculate CAI based on the gene expression programming (GEP) approach. This model is trained and tested based on a database collected from the experimental results available in the ...

The effect of concanavalin A (Con A) on the concentration of ionized intracellular calcium [( Cai++]) in human granulocytes (PMN) was monitored using the fluorescent calcium indicator and chelator, Quin2. The addition of Con A to PMN resulted in a rise in [Cai++] that was markedly enhanced by the presence of Ca++ in the external buffer. The onset of the increment in [Cai++] preceded the onset o...

background: epstein-barr virus (ebv) has a great co relationship with human malignancies such as gastric carcinoma. synonymous codon investigations in viruses could help designing vaccine, to generate immunity. codon adaptation index (cai) has measured translation elongation rate, among the highly expressed genes. the aim of this study was: usage of “cai” to measure translation efficiency to kn...

ERINGAITE-BEARING ULTRA-REFRACTORY CAI A. N. Krot, K. Nagashima, C. Ma, G. J. Wasserburg. HIGP, U. Hawai‘, USA. CalTech, USA. Introduction: Forsterite-bearing Type B (FoB) Ca,Al-rich inclusions (CAIs) are a rare type of coarse-grained igneous CAIs found almost exclusively in CV3 chondrites [1–5]. Here we describe the mineralogy, petrography, and oxygen-isotope compositions of a FoB CAI Al-2 fro...

Increasing free intracellular Ca (Cai) from less than 0.1 microM to 10 microM by means of A23187 activated Ca-stimulated K transport and inhibited the Na-K pump in resealed human red cell ghosts. These ghosts contained 2 mM ATP, which was maintained by a regenerating system, and arsenazo III to measure Cai. Ca-stimulated K transport was activated 50% at 2-3 microM free Cai and the Na-K pump was...

هدف: امروزه کارگروهی در مؤسسات آموزش عالی به‌عنوان یکی از بهترین راهبردها برای تعامل و مشارکت دانشجویان فرایند یادگیری هم‌چنین کمک به رشد مهارت‌های ارتباطی آن‌ها محسوب می‌شود. درحالی‌ که شناسایی مزایای می‌تواند درک مثبتی را بین اساتید ایجاد کند، عواملی باعث عدم شکل‌گیری تمایل اندک انجام نظام دانشگاهی می‌شود، نیز مزایا تأثیرات مثبت آن بکاهد؛ بنابراین، هدف این پژوهش چالش‌های مرتبط با بود.مواد روش...

This article examines current and future developments in the field of CAI using a model called ―CAI-NPD-Systems Maturity Model‖. This model is based on two aspects of the CAI systems development: The development in innovation theory and models such as Stage Gate or Open Innovation, and the development in the technologies-supporting software approaches such as Web2.0 to develop new generations o...

Ankle sprain is one of the most commonly damaged lower extremities. More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (Coper people) and do not suffer from chronic ankle instability. The aim of this study was to compare EMG activity of the selected involved muscles in balance control strategies in athletes with c...
