septicemia in neonates is the commonest cause of mortality. early recognition and diagnosis of neonatal sepsis remains a challenge because of the variable and nonspecific clinical presentation. the laboratory criteria are often non specific and not fully reliable. the objective of this review is to highlight the various hematological and biological markers of neonatal sepsis. we searched pubmed...
the current study is an attempt to investigate the impact of explicit instruction of metadiscourse markers on advanced, intermediate, and elementary efl learners’ writing performance. the participants of the study were 94 undergraduate students majoring in english literature at the university of isfahan. to elicit the relevant data, participants were given a pretest of writing ability to check ...
breeding for resistance is one of the main approaches to control diseases. in this approach, there is a necessary for existence a sufficient genetic variability of resistance genes. accordingly, assessing the genetic variability in the available germplasm is needed to manage genetic resources. molecular markers are effective tools to investigate genetic diversity for resistance to pathogens. nb...
This study investigated two major types of metadiscourse markers as used in typical sales contracts, written by English natives and Iranian non-natives. In so doing, 60 sales contracts were selected, 30 written by native English and 30 by Iranian non-natives. Based on Hyland and Tse’s taxonomy, the contracts were codified and classified in terms of the frequency and percentage of the interactiv...
of high-quality vegetable and industrial oil. 9 rapd primers, 6 aflp primer combinations and 12 agro-morphological traits were used to assess the genetic diversity of 20 accessions of saf flower representing global germplasm variability. jacquards’ similarity coef ficient were used to understanding the genetic relationships among ccessions, for aflp and rapd markers and euclidian similarity coe...
throughout the present study the effect of using markers close to genes affecting a trait, ascompared with the use of all the markers of a genome, and also the effect of on increase in thenumber of reference groups, on the accuracy of a genetic evaluation, was investigated. genomicevaluation was done using blup method. the results indicated that use of markers close to genesaffecting a trait an...
The domesticated silkworm, Bombyx mori, is of high commercial importance as a silk producer and is also widely used for implementation of basic and applied research. It is important to understand its genome organization using molecular markers for genetic studies and for breeding purposes. In this study, a genetic linkage map using 204 amplified fragment length polymorphism (AFLP) markers was d...
Aeluropus littoralis is one the most successful monocot grasses in terms of high salinity tolerance, that contains forage quality and has valuable physiological features. The goal of this study is to introduce and provide quick access to DNA-based molecular markers for valuable halophyte, Aeluropus littoralis to assessment of genetic diversity. For this, a total number of 110 EST-SSR ma...

Meta-discourse markers are an inevitable part of oral proficiency which improve both the quality and comprehension of learners’ speech. While studies of oral meta-discourse have been conducted since the 1980s in a European or US context, they have remained relatively untouched in Iran. Therefore, this study aimed to seek the impact of both explicit and implicit teaching of formal meta-discourse...
