This paper presents the reconstruction of the 80year time series of daily global solar radiation (GSR) at the subtropical high-mountain Izaña Atmospheric Observatory (IZO) located in Tenerife (The Canary Islands, Spain). For this purpose, we combine GSR estimates from sunshine duration (SD) data using the Ångström–Prescott method over the 1933/1991 period, and GSR observations directly performe...
Glutathione reductase (GSR), a key member of the glutathione antioxidant defense system, converts oxidized glutathione (GSSG) to reduced glutathione (GSH) and maintains the intracellular glutathione redox state to protect the cells from oxidative damage. Previous reports have shown that Gsr deficiency results in defects in host defense against bacterial infection, while diquat induces renal inj...
امتیازدهی ژئوفیزیکی توده سنگ (GSR)، که در این مطالعه برای مخازن کربناته معرفی شده است، یک امتیازدهی تجربی از مقاومت ژئومکانیکی سنگها است. GSR یک امتیازدهی از 10 تا 100 را فراهم میکند که مقادیر پایین مربوط به سنگهایی هستند که از لحاظ مقاومتی و پایداری دیواره چاه ضعیف هستند و سنگهای شیلی و نیز سنگهای مخزنی با تخلخل و تراوایی بالا را در بر میگیرند. در مقابل، مقادیر بالای GSR در ارتباط با ...
OBJECTIVE Infants with gastroschisis (GS) still face severe morbidity. Prenatal closure may prevent gastrointestinal organ damage, but intrauterine GS repair (GSR) has not been established yet. METHODS In New Zealand White rabbits we developed and compared GS versus GSR: creation of GS was achieved by hysterotomy, right-sided laparotomy of the fetus and pressure on the abdominal wall to provo...
BACKGROUND Tibial lengthening is frequently associated with gastrocsoleus contracture and some patients are treated surgically. However, the risk factors associated with gastrocsoleus contracture severe enough to warrant surgery during tibial lengthening and the consistency with which gastrocsoleus recession (GSR) results in a plantigrade foot in this setting have not been well defined. QUEST...
در بررسی خصوصیات مخزنی تخمین درست مقادیر پتروفیزیکی و پارامترهای مخزن مانند تخلخل، حجم شیل، جنس و سختی سنگ ها، رطوبت و شکستگی های موجود در سنگ در میادین و مخازن نفتی از اهمیت ویژه ای برخوردار است، این مطلب خصوصا" برای توسعه میادین نفتی و حفر چاه های جدید میزان ریسک را پایین می آورد. نگار درجه بندی سختی چینه (gsr) این خصوصیت را دارد که با درنظر گرفتن تمام پارامترهای مذکور یک دید کلی از کیفیت سنگ...
Inspired by group-based sparse coding, recently proposed group sparsity residual (GSR) scheme has demonstrated superior performance in image processing. However, one challenge in GSR is to estimate the residual by using a proper reference of the group-based sparse coding (GSC), which is desired to be as close to the truth as possible. Previous researches utilized the estimations from other algo...
The focus of analyzing data from microarray experiments has shifted from the identification of associated individual genes to that of associated biological pathways or gene sets. In bioinformatics, a feature selection algorithm is usually used to cope with the high dimensionality of microarray data. In addition to those algorithms that use the biological information contained within a gene set ...
Glutathione (GSH) and GSH-dependent enzymes play a key role in cellular detoxification processes that enable organism to cope with various internal and environmental stressors. However, it is often not clear, which components of the complex GSH-metabolism are required for tolerance towards a certain stressor. To address this question, a small scale RNAi-screen was carried out in Caenorhabditis ...
