The present paper focused on the sociocultural explanations of rhetorical differences between English and Persian and was based on the contrastive genre analysis of Applied Linguistics research article abstracts in these two languages. The evolutionary nature of research article abstracts was also investigated from 1985 to 2005, in three stages, with a time interval of 10 years. Seventy eight r...

In this paper, we have tried to predict earthquake events in a cluster of seismic data on pacific ring of fire, using multivariate adaptive regression splines (MARS). The model is employed as either a predictor for a sequence prediction task, or a binary classifier for a sequence recognition problem, which could alternatively help to predict an event. Here, we explain that sequence prediction/r...

background: genetic polymorphism of milk proteins has been associated with composition, manufacture, and traits of milk. caseins are the most important milk proteins whose genes are strongly linked and inherited as a raceme. κ-casein which is a quantitatively minor constituent of bovine milk is thought to play a critical role in organization, fixation and aggregation of casein micelles and firm...

in the present paper, we introduce the sequence space [{l_p}(e,delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left|  sum_{j in {e_n}} x_j - sum_{j in e_{n + 1}} x_jright| ^p < infty right},] where $e=(e_n)$ is a partition of finite subsets of the positive integers and $pge 1$. we investigate its topological properties and inclusion relations. moreover, we consider the problem of fin...

in this paper the notion of rees short exact sequence for s-posets is introduced, and we investigate the conditions for which these sequences are left or right split. unlike the case for s-acts, being right split does not imply left split. furthermore, we present equivalent conditions of a right s-poset p for the functor hom(p;-) to be exact.

conclusions in this study, phylogenetic reconstruction of hcv-1 sequences clearly indicated for molecular tracing and ancestral relationships of the hcv genotypes in iran, and showed the likelihood of domestic origin for hcv-1a and various origin for hcv-1b. evidence acquisition the phylogenetic analyses were performed based on the nucleotide sequences of ns5b gene of hcv genotype 1 (hcv-1), wh...

tumor necrosis factor-related apoptosis-inducing ligand (trail), a member of tnf family, is an interesting ligand which selectively induces apoptosis in tumor cells and, therefore, it has been developed for cancer therapy. this ligand has been produced by various hosts such as e.coli. however, protein expression in e.coli cytoplasm leads to problems such as incorrect folding, reduction in biolo...

background: salmonella enterica serovar typhimurium is one of the most important serovars of salmonella enterica and is associated with human salmonellosis worldwide. many epidemiological studies have focused on the characteristics of salmonella typhimurium in many countries as well as in asia. this study was conducted to investigate the genetic characteristics of salmonella typhimurium using m...
