since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
Two female patients presented with multiple radiolucent lesions noted on panoramic radiography. Cone-beam computed tomography (CBCT) scans confirmed “punched-out” affecting the skull.
Recent studies have shown association of mtDNA background with cancer development. We analyzed mitochondrial DNA (mtDNA) control region variation of 201 patients with nasopharyngeal carcinoma (NPC) and of 201 normal controls from Chaoshan Han Chinese to discern mtDNA haplogroup effect on the disease onset. Binary logistic regression analysis with adjustment for gender and age revealed that the ...
Thallium-201 myocardial scintigraphy was performed in patients with congenital heart defects to determine whether, by quantification of right ventricular isotope uptake, one could assess the degree of right ventricular hypertrophy and so predict the level of right ventricular pressure. A total of 24 patients ranging in age from 7 months to 30 years was studied; 18 were studied before corrective...

هدف تحقیق حاضر ریزکردن دانه های فولاد aisi 201 حاوی نیوبیوم تا محدوده نانومتری و یا فوق ریزدانه به کمک فرایند مارتنزیت و در نهایت مقایسه خواص مکانیکی آن (به ویژه انعطاف پذیری) با فولاد فاقد نیوبیوم بود. بدین منظور نمونه ها ابتدا در قالب فلزی ریخته گری شد و سپس تحت عملیات همگن سازی در دمای c° 1200 به مدت 15 ساعت قرار گرفت. به منظور ریزکردن دانه ها و تهیه نمونه های با ابعاد مناسب جهت فرایند نورد ...
OBJECTIVES With the increasing use of multi-detector CT, the number of detected cases with coronary-to-pulmonary artery fistula (CPAF) has increased. Several previous studies reported severe cases of angina, but no appropriate tests to evaluate myocardial perfusion for patients with CPAF have been established. We evaluated the hemodynamic characteristics of CPAF using thallium-201 (Tl-201) sing...
