this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...

one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...

the influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. this study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (olhe). olive leaves were collected from gardens around the city of shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. the influ...

background: rna interference (rnai) is the mechanism of gene silencing-mediated messenger rna degradation by small interference rna (sirna), which becomes a powerful tool for in vivo research, especially in the areas of cancer. in this research, the potential use of an expression vector as a specific sirna producing tool for silencing of bcr-abl in k562 cell line has been investigated. methods:...

expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

in order to study of drought tolerance levels in some wheat lines and cultivars based on uniform regional wheat yield trial (urwyt-m-75) an experiment was carried out using a strip plot design based on complete block design with 3 replications for two years (1998-2000) in torogh agricultural research station (mashhad, iran). the main plots (horizontal factor) were 3 levels of irrigation: 10, 20...

sea shores of gilan province is one off the biggest tourist attractions in iran. this area have valuable forests and grasslands. in addition it provides significant amount of corps like rice, tea, olive. considering this facts, environmental protection of this area must be priority for national government. however waste management instruction have been ratified in iran, there isn’t any specific...

plasters are produced from a light refractory material, mainly mgo (m.p. 2800ºc), a binder, and a void forming substance for insulating purposes. different oxides from the slag penetrate into these voids and provide low melting-point phases suchasrhodonite (mnsio3) (1290ºc), tephorite (mn2sio4) (1345ºc), merwinite (ca3mgsi2o8) (1575ºc), monticellite (camgsio4) (1490ºc), and enstatite (mgsio3) (...
