تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
The detection of genetically modified (GM) materials in food and feed products is a complex multi-step analytical process invoking screening, identification, and often quantification of the genetically modified organisms (GMO) present in a sample. "Combinatory qPCR SYBRGreen screening" (CoSYPS) is a matrix-based approach for determining the presence of GM plant materials in products. The CoSYPS...
abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
In sturgeon, female-sex rearing is economical and gynogenesis induction is one of the ways to achieve it. In gynogenesis, an egg develops without the genetic influence of the male, or on the other words, it is a method of reproduction in which the offspring are formed exclusively from the genetic information of the mother. In this technique, the sperm used must be genetically inactivated. Rays ...
Introdution: Presence of mentally retarded children as a source of pressure can jeopardize the general health of parents, especially mothers. The range of effect depends on the recognitive evaluation and the individual. The aim of this study was to investigate the effect of coping-therapy on mental health of mothers with genetically and non genetically mentally retarded children referring to Ya...
The evolution of reproductive isolation without geographic isolation (sympatric speciation) has recently gained strong theoretical and empirical supports. It is now widely admitted that many host-specific phytophagous insect species have arisen through shifting and adapting to new plants. The pea aphid Acyrthosiphon pisum has received considerable attention in this context and is now considered...
Coevolution between male and female traits can result from correlated responses to selection or correlated selection on genetically independent traits. This study examines the possibility that traits involved in precopulatory sexual selection may influence the evolution of traits involved in postcopulatory sexual selection due to the existence of correlated selection or correlated responses to ...
Reduced renal 15-hydroxyprostaglandin dehydrogenase (PGDH) activity has been proposed as a cause, subsequent to elevation of intrarenal prostaglandin (PG) E2 levels, of the development or maintenance of high blood pressure (BP) in the New Zealand genetically hypertensive (NZGH) rat. To test this hypothesis, PGDH activity in homogenates of kidneys and lungs and in urine concentration and excreti...
Long-term rearing of Cynops pyrrhogaster and ensicauda popei confirmed that the longevities two species were longer than 36 years; C. 37 years e. years, respectively. The male was 34 old or older showed reproductive behavior with a conspecific young female successfully bred. paternal relationships between six offspring also genetically proven, indicating retained its fertility at age older. Sin...
Mice derived entirely from embryonic stem (ES) cells can be generated through tetraploid complementation. Although XY male ES cell lines are commonly used in this system, occasionally, monosomic XO female mice produced spontaneous Y chromosome loss. Here, we describe an efficient method to obtain by CRISPR-Cas9-mediated deletion of the chromosome, allowing generation clonal The viable and able ...
