the present study was conducted to find the effect of three heavy metals, ag, hg and pb on the expression level of a gene encoding plasma membrane h+-atpase in aeluropus littoralis. the experiment was laid out in a completely random design with three replications. the expression of the main gene was normalized to the expression of the housekeeping gene actin. two 259 and 187 bp fragments were a...
this study investigated the effects of three kinds of gloss conditions, that is traditional non-call marginal gloss, audio gloss, and extended audio gloss, on reading comprehension and vocabulary gain of iranian upper- intermediate efl learners. to this end, three experimental and one control groups, each comprising 15 participants, took part in the current study. in order to ensure that the pa...
The present work was designed to study the effect of different concentrations of bovine serum albumin (BSA) in extender on post-thaw quality of buffalo spermatozoa. Semen was collected from three buffalo bulls with artificial vagina (42°C) for three weeks (replicates). Qualifying semen ejaculate from each bull was split into five aliquots and diluted in tris-citric egg yolk extender containing ...
Pig breeding is mainly conducted through Artificial Insemination (AI) in Western and developing countries. Apart from requiring specific catheters and trained staff, preserving boar semen in proper conditions is needed to ensure high reproductive performances. Although, at present, boar sperm may be preserved in liquid (15-17oC) or frozen states, more than 95% of AIs are conducted using liquid ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
Effect of two animal protein-free extenders on cryopreservation of Pelibuey and Blackbelly ram semen
The study evaluated the effect of two animal protein-free extenders on ram semen cryopreservation tropical hair breeds. ejaculates were collected from 8 rams (4 Blackbelly and 4 Pelibuey), which mixed (pooled) by breed, diluted cryopreserved in three different extenders: Animal protein [Tris egg yolk (Triladyl®)], AndroMed® (lecithin soy bean) OPTIXcell® (liposome). Sperm analyses total (TM) pr...
The current research was designed to compare the effects of substitution egg yolk (EY) in ram extender with Arabic gum (AG) different concentration cooled or frozen semen collected by artificial vagina (AV) electro-ejaculator (EE) Noemi rams. Semen 2 times per week for 6 weeks from rams EE method and after a rest period weeks, samples were AV method. Tris either contained 15% EY (Control) 3%, 5...
