چکیده : در این مقاله یک طرح کنترلی برای عملکرد در حالت متصل به شبکه و در حالت جزیرهای برای تولیدات پراکنده، ارائه داده است. در شرایط نرمال، هر سیستم اینورتر DG در ریز شبکهها به منظور تامین توان از پیش تعیین شده به طور معمول در یک حالت کنترل جریان ثابت کار میکند. زمانی که ریزشبکهها از شبکه جدا میشوند، هرسیستم اینورتر DG باید شرایط جزیره ای بودن را تشخیص دهد و باید به حالت کنترل ولتاژ تغییر وضعیت...
alpha-Dystroglycan (alpha-DG) was recently identified as a receptor for lymphocytic choriomeningitis virus (LCMV) and several other arenaviruses, including Lassa fever virus (W. Cao, M. D. Henry, P. Borrow, H. Yamada, J. H. Elder, E. V. Ravkov, S. T. Nichol, R. W. Compans, K. P. Campbell, and M. B. A. Oldstone, Science 282:2079-2081, 1998). Data presented in this paper indicate that the affinit...
toxin, have been commonly used for the treatment of congestive heart failure and other cardiac diseases. In addition to the narrow therapeutic range of the serum digitalis glycosides, their bioavailability is easily affected by kidney or liver failure and the dosing of other medicines. Therefore, it is important to accurately measure the digitalis glycosides in sera from digitalized patients. D...
Modest antidepressant response rates of mood disorders (MD) encourage benzodiazepine (BZD) co-medication with debatable benefit. Adult hippocampal neurogenesis may underlie antidepressant responses, but diazepam co-administration impairs murine neuron maturation and survival in response to fluoxetine. We counted neural progenitor cells (NPCs), mitotic cells, and mature granule neurons post-mort...
We investigate the (unbounded) derived category of a diierential Z-graded category (=DG category). As a rst application, we deduce a 'triangulatedanaloguè (4.3) of a theorem of Freyd's 5, Ex. 5.3 H] and Gabriel's 6, Ch. V] characterizing module categories among abelian categories. After adapting some homological algebra we go on to prove a 'Morita theorem`(8.2) generalizing results of 19] and 2...
abstract: in this paper a control scheme for grid-connected operation mode and the island state of distributed generation is presented. in normal conditions, every inverter dg system in micro-grids to supply a preset power, normally operate in a constant current control mode. when micro-grids removed from the network, dg inverter of each system must recognize the island and change position to v...
The insertion of distributed generator (DG) into distribution systems for performance improvement has been an obvious application. But the choice of DG has been extended to the networked systems as well in the recent years. The penetration level of DG is accelerating due to the liberalization of electricity markets and Technological advances in small generators and energy storage devices. In th...
OBJECTIVE To understand how aquaporin4 (AQP4) and dystroglycan (DG) polarized distribution change and their roles in brain edema formation after traumatic brain injury (TBI). METHODS Brain water content, Evans blue detection, real-time PCR, western blot, and immunofluorescence were used. RESULTS At an early stage of TBI, AQP4 and DG maintained vessel-like pattern in perivascular endfeet; M1...
Disordered gambling (DG) will soon be included along with the substance use disorders in a revised diagnostic category of the Diagnostic and Statistical Manual of Mental Disorders DSM-5 called 'Substance Use and Addictive Disorders'. This was premised in part on the common etiologies of DG and the substance use disorders. Using data from the national community-based Australian Twin Registry, we...
The steady-state brain/plasma distribution ratios of [14C]deoxyglucose ([14C]DG) for hypoglycemic rats previously determined by measurement of DG concentrations in neutralized acid extracts of freeze-blown brain and plasma exceeded those predicted by simulations of kinetics of the DG model. Overestimation of the true size of the precursor pool of [14C]DG for transport and phosphorylation could ...
