introduction lori sheep is one of the most important breeds in iran that is mostly bred in lorestan province, north-east of khuzestan and some areas of ilam provinces. the name of this breed is derived from lori tribe, which is one of the major nomadic groups of zagros mountain in western areas of iran. lori sheep is resistant to mountain conditions and hot and dry plains. this sheep breed has ...

Wendelstein 7-X is an optimised stellarator designed for steady-state operation. The only steadystate capable heating system is electron cyclotron resonance heating (ECRH) launching microwaves at 140GHz into the vessel corresponding to the 2nd harmonic of the electron cyclotron frequency at 2.5 T. A quasi optical transmission line is used to bring the power into the machine. The power is launch...

A novel fully integrated CMOS LC tank VCO is presented. The LC tanks are implemented by exploiting the active circuit ‘boot-strapped inductor’ (BSI), which behaves like a high-quality factor inductor. Particularly, the LC tanks have been implemented by introducing a new version of the CMOS BSI circuit, which provides better versatility and design reliability. In order to verify the effectivenes...

In order to meet the versatile power requirements of the autonomous underwater vehicles (AUV), we propose a rechargeable lithium-bromine/seawater fuel cell with a protected lithium metal anode to provide high specific energy at either low-power mode with seawater (oxygen) or high-power mode with bromine catholytes. The proof-of-concept fuel cell with a flat catalyst-free graphite electrode can ...

Power dissipation is major drawback in the digital sequential circuit design of low power electronic devices. Clock signal is one input which is common for all the sequential circuits. The clock signal has major power dissipation at high frequencies. The clock gating technique can be implemented at architectural level to reduce the power dissipation at dynamic and clock power level. Aim of this...

OBJECTIVE The purpose of this study was to evaluate the safety and efficacy of transepithelial corneal collagen cross linking (TE-CXL) with modified riboflavin and accelerated UVA irradiance in thin corneas with pachymetry less than 400 microns at thinnest point, untreatable by epithelium off corneal collagen cross linking (CXL) in adult Pakistani population with progressive keratoconus. METH...

Applications In this paper A single chip 2.4GHz low power CMOS receiver and transmitter for WPAN applications are implemented and measured. The receiver uses a low-IF architecture with a polyphone filter and transistor linearization technique to improve linearity per power, and the transmitter adopts a ROM based direct-conversion architecture for low power consumption and high integrated densit...

The modulation of collagen fibers during experimental skin wound healing was studied in 112 Wistar rats submitted to laser photobiomodulation treatment. A standardized 8mm-diameter wound was made on the dorsal skin of all animals. In half of them, 0.2ml of a silica suspension was injected along the border of the wound in order to enhance collagen deposition and facilitate observation. The other...

baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...
