Cat scratch disease (CSD) is a self limited condition characterized by fever, lymph node enlargement and less often eye involvement. Central nervous system involvement by Bartonella henselae infection is possibly an important cause of morbidity; its role as an agent of aseptic meningitis is unknown. We report a case of a 40 years-old man with CSD accompanied by aseptic meningitis and neuroretin...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...
ددر این تحقیق استفاده از کربن اکتیو ، ذرات نانو مغناطیسی آهن و ذرات نانو کامپوزیت آهن- کربن اکتیو، برای حذف رنگ آنیونی از پسابهای سمی مورد مطالعه قرار گرفتند . رنگ direct orange -26 به عنوان مدلی از رنگ آنیونی مورد بررسی قرار گرفت. مشخصات سطحی نانو ذرات آهن و نانو کامپوزیت آهن توسط sem مورد بررسی قرار گرفت . تاثیر عوامل مختلف (ph ، دوز جاذب، زمان تماس، دور هم زدن) به روش طراحی آزمایش تاگوچی مور...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
the notion of baer modules was defined recently
یکی از علت های شکست و عدم موفقیت در تکنیک های کمک باروری(art) قطعه قطعه شدن dna اسپرم انسانی است، که ممکن است با انکوباسیون طولانی مدت اسپرم در دمای 37 درجه سانتی گراد به وجود آید. لذا در این مطالعه میزان قطعه قطعه شدن و آپوپتوز dna اسپرم انسانی بعد از آماده سازی به روش direct swim-up در زمان های مختلف انکوباسیون به وسیله تست scd و تکنیک tunel مورد ارزیابی قرار گرفت. در این مطالعه آینده نگر، ب...
