We investigate this issue in post-war Sierra Leone, one of the world’s poorest countries. To address concerns over endogenous local ethnic composition, and in an advance over most existing empirical work,...
According to researches, one of the productivity barriers among many organizations is assembly line balancing problem, which needs scientific models to be solved. This paper examines the effect of line balancing on the functioning of assembly line in two sections.

یکی از عناصر مهم سیستم قدرت جهت حفاظت در برابر اضافه ولتاژها برقگیر ها می باشند. افزون بر سه دهه از استفاده برقگیر های اکسید فلز (metal oxide surge arrester) در صنعت برق می گذرد و امروزه بطور وسیع در رده ولتاژهای مختلف از آنها استفاده می شود. وقوع بسیاری از خرابیهای گسترده چه از لحاظ مالی و چه از لحاظ جغرافیایی نتیجه عدم عملکرد به موقع برقگیرهاست. لذا ضروری است که از سالم بودن برقگیر در محل نصب...
ترهالوز یک دی ساکارید غیر احیاکننده است که در موجودات زنده مختلف از باکتری ها و قارچ ها تا بی مهرگان وجود دارد و به عنوان یک منبع انرژی، اسمولایت و محافظ غشا و پروتئین عمل می کند. بطور کلی، مقدار ترهالوز در گیاهان نسبتا کم است اما ممکن است که در پاسخ به تنش های محیطی تغییر کند. تنش خشکی یکی از اصلی ترین عوامل محیطی محدود کننده رشد و تولید مثل گیاهان است. ذرتzea mays l.)

line n-78-14 with the pedigree of sha4/chil cm91099-25y-om-3n-1y-oyz-o10m-oy-3m-o10 was obtained from cimmyt, mexico in 1996 through high rainfall wheat screening nursery. preliminary evaluation of the genotypes in international nursery in gorgan and sari research stations during 1996-97 cropping season, resulted in selection of this line as one of the most high yielding genotypes. selected lin...
In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...
Public health care in Canada (“medicare”) is based on five principles, and its realization balances precariously on the method by which this public service is provided.1 At one end of the delivery spectrum, medicare could be a fully decommodified public service similar to the public education system; at the other end, public health care insurance could exist alongside the private, for-profit de...

Cross-Resistance of Acquired Radioresistant Colorectal Cancer Cell Line to gefitinib and regorafenib
Background: Usually, chemoradiotherapy can be used for the treatment of locally advanced colorectal cancer (CRC) before surgery. On the other hand, some studies have shown that fractional radiation of tumor cells leads to chemoresistance. The aim of this study was to evaluate the chemoresistance of radioresistant sub-line (RR sub-line).Methods: This study was done in Hamadan University of...
