abstract background: regarding the diagnostic errors of the classic criteria including serum ascites albumin gradient (saag), total protein concentration and the adapted light et al’s criteria in distinguishing transudate versus exudates, we evaluated the ascitic fluid to serum bilirubin ratio as a new criteria in this regard. we also evaluated whether the combination of bilirubin ratio with ea...
Studies assessing phenotypes of plant populations traditionally place their primary focus on increasing measurement precision and improving accuracy. Phenotyping methods that use imaging, remote sensing, spectroscopy, continue to increase throughput capacity, but information has been unavailable assess the tradeoffs between increased any potential decreases in In this simulation study, we compa...
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 accuracy and precision of 3 lactation models was estimated by summarizing means and variability in projection error for next-test milk and actual 305-d milk yield (M305) for 50-d intervals in a large Dairy Herd Improvement Association data set. Lactations were grouped by breed (Holstein, Jersey, and crossbred) and parity (first vs. later). A smaller, single-herd data set with both Dairy Her...
Extended Abstract Background and objectives: Google Earth images are a valuable resource for understanding and studying the natural area's ecology due to their high spatial resolution. Considering that these images have been available for many years, in our country, these valuable data have not been used enough, especially in order to study vegetation and optimal natural areas management. So, ...
