New battery systems having high energy density are actively being researched in order to satisfy the rapidly developing market for longer-lasting mobile electronics and hybrid electric vehicles. Here, we report a new Li-Te secondary battery system with a redox potential of ~1.7 V (vs. Li(+)/Li) adapted on a Li metal anode and an advanced Te/C nanocomposite cathode. Using a simple concept of tra...
The aim of this study is to investigate the context by which veterinary services may affect technical efficiency (TE) of Iranian dairy farms. A data envelopment analysis (DEA) was applied to a random sample of 840 dairy farms from six provinces across Iran to estimate regional frontier and metafrontier production functions and also to calculate corresponding TE of these farms. The relationship ...
(Bi2Te3)0.25(Sb2Te3)0.75 solid solution is a p type thermoelectric compound with optimum efficiency among the (Bi2Te3)x (Sb2Te3)1-x compounds with variable x. Increment of Bi2Te3 segment in the Bi-Sb-Te system decrease in hole concentration, which result in carriers transport tuning, an increment of Seebeck coefficient and decrement of electrical and thermal conductivities. An excess of Telluri...
Background: Tennis elbow (TE), as a lateral epicondylitis (LE), is a chronic inflammatory and degenerative tendon disease that causes pain in the outer part of the elbow. This study aimed to evaluate the efficacy of topical Trinitrate Glyceryl (GTN) in the treatment of patients with TE. Materials and methods: In this double-blind clinical trial, 90 patients with TE, referred to Orthopedic and R...
In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...
اکستروژن پیچشی (te) به عنوان یکی از روش های توسعه یافته و نویدبخش spd (تغییرشکل پلاستیک شدید) شناخته می شود که با اکسترود کردن یک نمونه ی شمشه ای از میان یک قالب با یک مسیر پیچی شکل انجام می شود. در تحقیق حاضر، از قالب اکستروژن پیچشی با زاویه پیچش 30 درجه استفاده شد و ریزساختار و خواص مکانیکی آلیاژ آلومینیوم 6063 قبل و بعد از فرایند te بررسی گردید. به دلیل ثابت بودن ابعاد اصلی قطعه کار بعد از ا...
