Many authors have examined lot sizing, scheduling and sequence of multi-product flow shops, but most of them have assumed that set up times are independent of sequence. Whereas dependence of set up times to sequence is more common in practice. Hence, in this paper, we examine the discussed problem with hypothesis of dependence of set up times to sequence and cyclic schedule policy in basic peri...

The notion of quasi-exact sequence of modules was introduced by B. Davvaz and coauthors in 1999 as a generalization of the notion of exact sequence. In this paper we investigate further this notion. In particular, some interesting results concerning this concept and torsion functor are given.

in this paper we introduce entire sequence spaces defined by a sequence of modulus functions . we study some topological properties of these spaces and prove some inclusion relations.

in this paper we introduce some new double sequence spaces using the orlicz function andexamine some properties of the resulting sequence spaces.

Background: Deoxyribozymes (Dzs) can play a role as gene expression inhibitors at mRNA level. Among Dzs, the 10-23 deoxyribozyme has significant potentials for treatment of diseases. Designed Dz includes a catalytic core made of 15 deoxyribonucleotides and two binding arms consisted of 6-12 nucleotides for site specific binding to target RNA and hydrolysis. The enzyme has characteristic feature...

Very little is known about LHR and FSHR genes of domestic dromedary camels. The main objective of this study was to determine and analyze partial genomic regions of FSHR and LHR genes in dromedary camels for the first time. To this end, a total of 50 DNA samples belonging to dromedary camels raised in Iran were sent for sequencing (25 samples of each gene). We compared the nucleotide sequences ...

background: the number of reported cases, infected with carbepenem resistant acinetobacter baumannii (crab) and multi-drug resistant (mdr) acinetobacter species had gradually increased in most pla general hospital wards from april to june in 2007. objectives: we have described the investigation of an outbreak of crab and mdr acinetobacter in pla general hospital, beijing. the prospective and re...
