OBJECTIVE To investigate the changes of activation of the abdominal muscles depending on exercise angles and whether the activation of rectus abdominis differs according to the location, during curl up and leg raise exercises, by measuring the thickness ratio of abdominal muscles using ultrasonography. METHODS We examined 30 normal adults without musculoskeletal problems. Muscle thickness was...
Due to isospin suppression of the otherwise dominant low-energy isovector WeinbergTomosawa πN term in the re-scattering diagram, and the negative interference between the remaining impulse and isoscalar pion re-scattering terms[1], the empirical data for pp → ppπ near threshold is only explained by phenomenological non-pionic, short-range, twobody mechanisms[2], or alternatively by an off-shell...
در این پایان نامه متر های ریشه -mام انیشتینی را مورد بررسی قرار داده و نشان می دهیم که اگر f یک متر انیشتینی ریشه -mام باشد ، یعنی ric=(n -1 ) kf*f که در آن k یک تابع اسکالر می باشد ،آنگاهk=0 لذا ric=0. همچنین این خاصیت را برای متر های ریشه m-ام انیشتن ضعیف شده مورد بررسی قرار می دهیم. لازم به ذکر است مطالب ذکر شده از مقاله زیر است: y. yu and y. you, on einstein m-th...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
A total of 30 ejaculates from three Hampshire crossbred boars were used to study the effect of freezing rates and thawing methods on quality of frozen boar semen. Semen was frozen using three freezing rates-30 0 c/min, 50 0 c/min and 70 0 c/min in a programmable biological semen freezer. The semen characteristics viz., sperm motility, live sperm, HOST reacted spermatozoa and intact acrosome wer...
the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
