Discourse markers improve both the quality and comprehension of a written text. This study aimed at investigating the effect of explicit and implicit instruction of formal meta-discourse markers on writ- ing skills. The quantitative data were collected from 90 upper-intermediate students at Shiraz Univer- sity Language Center. Two experimental groups went through an instruction, while the contr...

Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...

background: genetic diversity of three polymorphic markers in the phenylalanine hydroxylase (pah) gene region including pvu ii (a), pahstr and msp i were investigated. methods: unrelated individuals (n=139) from the iranian populations were genotyped using primers specific to pah gene markers including pvu ii(a), msp i and pahstr. the amplified products for pvu ii(a), msp i were digested using ...

research article (ra) genre has been a significant area of research in academic writing over past decades. however, authors’ identity in ras has not received much attention, especially in soft sciences like applied linguistics. this paper reports a corpus analysis of iranian writers’ authorial presence markers in ras in the field of applied linguistics. the corpus comprised 30 ras (200,000 word...

alzheimer disease (ad) is a neurodegenerative disorder and the most common form of dementia. increasing evidence suggests that alzheimer's disease pathogenesis is not restricted to the neuronal compartment, but includes strong interactions with immunological mechanisms in the brain. in vitro and animal studies have linked neuroinflammation to alzheimer's disease (ad) pathology. studie...

  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 ...

the study investigates the possibility of sex determination of rainbow trout (oncorhynchus mykiss)using molecular screen for products monosex of populations. 35 caudal fin tissue samples wereobtained from karaj rainbow trout mature population and then genomic dna was extracted andmarker loci amplified. polymerase chain reaction (pcr) was setup based on two omyfa andomyfatu markers for amplifica...

objective(s): iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. however, to date there is no reliable information on the application of the markers in the iranian pop...
