In this paper, we propose three new tests for serial correlation in the disturbances of fixed-effects panel data models. First, a modified Bhargava, Franzini and Narendranathan (1982) panel Durbin-Watson statistic that does not need to be tabulated as it follows a standard normal distribution. Second, a modified Baltagi and Li (1991) LM statistic with limit distribution independent of T , and, ...
This research was carried out to investigate the heterogeneity of milk yield variance components in different production levels of holstein cattles. The first lactation milk yield records of 95945 Holstein cattles, which had calved in 651 herds through years 1991 to 2000, were used in this research. Data was collected by the Animal Breeding Center of Iran and adjusted for two-time milking per d...
چکیده : مالتیپل میلوما بدخیمی خونی است که با افزایش تکثیر پلاسماسل های مونوکلونال در مغز استخوان همراه می باشد . ضایعات استئولیتیک این بیماری موجب دردهای شدید استخوانی ، شکستگی های پاتولوژیک استخوانی ، افزایش کلسیم و فشردگی طناب نخاعی می گردد . مکانیسم سلولی اصلی که باعث ایجاد بیماری استخوانی در میلوما می شود شامل واکنش متقابل بین سلول میلومایی و ریز محیط مغز استخوان (microenviroment ) می باش...
Abstract The present study was conducted to determine the effect of learning self-regulation strategies on surface, deep and strategic learning approaches of high school first grade female students in Yazd. The study method was pre-test and post-test design. For this purpose, a sample size of 57 subjects was selected by multistage cluster sampling method among high school first grade female ...
Introduction Association of heart rate (HR) with mortality in patients with acute coronary syndrome (ACS) and aged ≥ 80 years are underrepresented in clinical trials. We therefore aimed to investigate the association of HR in atrial fibrillation (AF) versus sinus rhythm (SR) with all-cause mortality in octogenarian patients with ACS. Methods A total of 336 patients with ACS patients and aged ...

Circulating bilirubin, a natural antioxidant, is associated with decreased risk of type 2 diabetes (T2D), but the nature of the relationship remains unknown. We performed Mendelian randomization in a prospective cohort of 3,381 participants free of diabetes at baseline (age 28-75 years; women 52.6%). We used rs6742078 located in the uridine diphosphate-glucuronosyltransferase locus as an instru...
