Planning for electricity generation systems is a very important task and should take environmental and economic factors into account. This paper reviews the existing metrics and methods in evaluating energy sustainability, and we propose a sustainability assessment index system. The input indexes include generation capacity, generation cost, and land use. The output indexes include desirable an...

The effects of estrogen and ovariectomy on indexes of muscle damage after 2 h of complete hindlimb ischemia and 2 h of reperfusion were investigated in female Sprague-Dawley rats. The rats were assigned to one of three experimental groups: ovariectomized with a 17beta-estradiol pellet implant (OE), ovariectomized with a placebo pellet implant (OP), or control with intact ovaries (R). It was hyp...

The risk of a coal burst rises with the excavation depth and other mining-related activities. These devastating activities are major concern during deep mining. During such activities, loading rate is cause damage. Different indexes, including elastic strain modulus index (Wet), bursting energy (Ke), dynamic failure time (DT), compressive strength (Rc), used for intensity; however, damage facto...

Evaluating SPARQL queries with the DISTINCT clause may become memory intensive due to the requirement of additional auxiliary data structures, like hash-maps, to discard the duplicates. DISTINCT queries make up to 16% of all the queries (e.g., DBPedia), and thus are non-negligible. In this poster we propose a novel method for such queries, by just manipulating the compressed bit-vector indexes ...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

OBJECTIVES There is limited evidence on the preferred methods for evaluating lung function in infancy. The objective of this study was to compare sensitivity and repeatability of indexes of lung function in young infants during induced airway obstruction. METHODS The study population consisted of 402 infants (median age, 6 weeks). Forced flow-volume measurements were obtained by the raised vo...

Background: Objective structured clinical examination (OSCE) is one of the best methods for evaluating the achievement of educational objectives and cognitive, emotional and psycho-motor aspects of medical students. The main purpose of this study was to determine the reliability and validity of OSCE method in evaluating knowledge and clinical practices of midwifery students in the courses of ph...

abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...

black humor plays a crucial role in fulfilling langston hughes's anti-racist purposes as an integral notionin his poetry. accordingly, translation(s) of his poetry are to benefit from the same indexes onthe basis of equivalent effect principle. on this account, 33 black-humor-rich poems of hughes, translatedby ahmad shamloo, yaghma golruee and hassan fayyad, were selected to be analyzed contras...
