واحدهای تولید پراکنده در کنار مزایای فراوان، اثرات منفی متعددی بر سیستم توزیع دارند. با وقوع خطا در موقعیت های گوناگون، اثرات منفی dg ناشی از افزایش سطح جریان خطا و تغییر جهت جریان در برخی خطوط می باشد. از مهمترین این اثرات می توان به فرمان قطع اشتباه، عدم مشاهده خطا، کاهش دسترسی تجهیزات حفاظتی و برهم خوردن هماهنگی میان این تجهیزات اشاره کرد. روش های مختلفی جهت کاهش اثرات منفی dg بر سیستم حفاظت...
Opinions vary regarding how much distiller’s grains (DG) can be used effectively in lactation rations. In order to better understand conflicting reports and recommendations about the effect of DG on milk yield we examined 23 studies about DG in the dairy science literature. Inclusion of DG in treatment diets ranged from 4 to 42% of dietary DM across all studies. Our analysis of the entire datab...
Three deoxyglucose (DG) derivatives, S-DG, MAG(3)-DG and MAMA-BA-DG, were synthesized and labeled successfully with high labeling yields and high radio-chemical purities. Biodistribution in tumor-bearing mice demonstrated that these three new (99m)Tc-deoxyglucose derivatives showed accumulation in tumor and high tumor-to-muscle ratios. Among them, the (99m)Tc-MAG(3)-DG showed the best character...
Turning to Renewable Energy Sources (RES) is the most logical politics in securing the modern society from critical changes in earth increasing temperature. However, Distributed Generation (DG) sources could lead to new challenges in electricity network, mainly allocation of DG sources in distribution level of power system will set the existing network under stress of power flow parameters. The...
alpha-Dystroglycan (DG) has been identified as the cellular receptor for lymphocytic choriomeningitis virus (LCMV) and Lassa fever virus (LFV). This subunit of DG is a highly versatile cell surface molecule that provides a molecular link between the extracellular matrix (ECM) and a beta-DG transmembrane component, which interacts with the actin-based cytoskeleton. In addition, DG exhibits a com...
We further investigate the high order positivity-preserving discontinuous Galerkin (DG) methods for linear hyperbolic and radiative transfer equations developed in [14]. The DG methods in [14] can maintain positivity and high order accuracy, but they rely both on the scaling limiter in [15] and a rotational limiter, the latter may alter cell averages of the unmodulated DG scheme, thereby affect...
The dystroglycans (alpha-DG and beta-DG), which play important roles in the formation of basement membranes, have been well studied in skeletal muscle and nerve, but their expression and localization in intestinal epithelial cells has not been previously investigated. Here, we demonstrated that the DG complex, composed of alpha-DG, beta-DG, and utrophin, is specifically expressed in the basolat...
OBJECTIVE 3-Deoxyglucosone (3-DG), a highly reactive intermediate of the glycation reaction, has been suggested to contribute to the development of diabetes complications. To verify this hypothesis, we assessed the relation between serum 3-DG concentrations and the severity of diabetic microangiopathy in diabetic patients. RESEARCH DESIGN AND METHODS We conducted a high-performance liquid chr...
The Danshen-Gegen formula (DG) is a traditional Chinese herbal formula which has long been used to treat cardiovascular disease. DG was found to be a cardiovascular tonic in our recent research. However, a comprehensive investigation of the molecular mechanism of DG in cardiovascular disease has not been performed. The aim of this study was to clarify the transcriptional profiling of genes modu...
