a novel ultra-high compliance, low power, very accurate and high output impedance current output stage (cos) with extremely high output current drive capability is proposed in this paper. the principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by hspice simulation in tsmc 0.18µm cmos, bsim3, and level4...
The dynamic behavior of three high manganese steels with very different stacking faultenergy (SFE) values (4-30 mJ/m2) were studied using high strain rate torsional tests. The hotrolledmicrostructure of the steel with the lowest SFE of 4 mJ/m2 consisted of a duplex mixture ofaustenite and ε-martensite, but those of the other two steels were fully austenitic. The deformedmicrostructures were stu...
many studies have shown the effectiveness of photorefractive keratectomy (prk) in correction of vision in low and moderate myopia. to evaluate the results of 193-nm exeimer laser photorefractive keratectomy for highly myopic eyes, we reviewed refractive outcome of 43 eyes of 30 patients. most eyes were treated with 1-step operation, using a 6 mm optical zone. 43 eyes were treated for myopia, wh...
یکی از مهمترین اصول رسیدن به سلامت فردی و اجتماعی که نهایتا به سلامت جامعه منجر می شود، شناسایی افرادی است که بیشتر در معرض آسیب قرار دارند . یک نوزاد هر چه در سنین پایین تردر معرض بیماری قرار گیرد ، دچار عوارض جبران ناپذیر و آسیب جدی تر خواهد شد. با شناسایی نوزادان high risk و ایجاد زمینه مناسب جهت رفع نیازمندیهای آنها، می توان از آسیب و عوارض جبران ناپذیر بعدی جلوگیری به عمل آورد . دراین ...
Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...
Agenda Objective 3 problems this paper try to solve Solutions to the three problems Small signal models analysis and simulation Test circuit and results Conclusion
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
Background: The affordable protocol to prevent the severe OHSS in two groups of patients PCO syndrome and non PCO high responder. Methods and Materials: PubMed and Medline were searched from January 2000 till end of May 2014. This Study investigates whether the mild protocol is associated to prevent severe OHSS in infertile female. Results: According to this survey, 9 studies were included and ...
in recent years there have been many attempts to develop and market inexpensive mixtures of high protein food for the children in developing areas of the world. biological studies have shown that these foods are rich sources of protein and are every effective in combating protein malnutrition. however, practical marketing and distribution has not been very successful due to the local people's h...
