Pegmatite-aplite dykes from north east of Lorestan Province is located about 25 km east of Boroujerd city and consists of three major zones, from outside to inside including graphic, layered and core zone that obviously shows the effect of fractional crystallization in pegmatites. Microprobe analysis performed on minerals (tourmaline, plagioclase and muscovite) from each three zones. Tourmaline...
In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
background and objectives: constant monitoring of healthcare organizations’ performance is an integral part of informed health policy-making. several hospital performance assessment methods have been proposed in the literature. pabon lasso model offers a fast and convenient method for comparative evaluation of hospital performance. this study aimed to evaluate the relative performance of hospit...

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
introduction: electrophysiological studies have demonstrated a relationship between aging and atrioventricular (av) nodal conduction and refractoriness. the aim of the present study was to determine the effects of nodal aging on dynamic av nodal field potential recording during atrial fibrillation (af) in rabbit. methods: two groups of male new zealand rabbits (neonatal 2-week-olds and adult 12...
