Carbon sequestration in agricultural soils has the capacity to mitigate greenhouse gas emissions, as well as to improve soil biological, physical, and chemical properties. The review of literature pertaining to soil organic carbon (SOC) dynamics within Australian grain farming systems does not enable us to conclude on the best farming practices to increase or maintain SOC for a specific combina...
The hardware-software automated partitioning of a RTOS in the SoC (SoC-RTOS partitioning) is a crucial step in the hardware-software co-design of SoC. First, a new model for SoC-RTOS partitioning is introduced in this paper, which can help in understanding the essence of the SoC-RTOS partitioning. Second, a discrete Hopfield neural network approach for implementing the SoC-RTOS partitioning is ...
Soil carbon sequestration and land use change associated with biofuel production: empirical evidence
Soil organic carbon (SOC) change can be a major impact of land use change (LUC) associated with biofuel feedstock production. By collecting and analyzing data from worldwide field observations of major LUCs from cropland, grassland, and forest to lands producing biofuel crops (i.e. corn, switchgrass, Miscanthus, poplar, and willow), we were able to estimate SOC response ratios and sequestration...
Soil organic carbon (SOC) was measured in topsoil samples of agricultural soils from 311 locations of Jiutai County, Northeast China. The spatial characteristics of SOC were studied using the Geographic Information Systems and geostatistics. Effects of other soil physical and chemical properties, elevation, slope, soil type and land use type were explored. SOC concentrations followed a lognorma...
در 38بیمار نوزاد تا 7ساله در طی یکسال در بیمارستان خاتم الانبیا (ص) که همگی از نظر کلینیکی مشکوک به ریفلاکس گاستروازفاژیال بودند جهت تشخیص باریم میل و سونوگرافی انجام شد و نتایج حاصله با هم مقایسه گردید. در بین بیماران فوق در 32 مورد نتایج یکسان بود بطوریکه 17 بیمار هم در سونوگرافی و هم در باریم میل ریفلاکس داشتند و در 15 بیمار هر دو منفی بود. در 4 بیمار نتیجه باریم میل مثبت و نتیجه سونوگرافی م...
برای رسیدن به سطوح بالای پوشش خطا، معمولا تغییرات زیادی در مقادیر سیگنالهای داخلی مدار ایجاد می گردد که باعث افزایش مصرف توان نسبت به حالت کار عادی مدار است. علاوه بر این آزمون مبتنی بر پویش در زمان شیفت دادن بردارها تعداد زیادی گذار در ورودی مدار تحت آزمون ایجاد می نماید که این مسئله باعث فعالیتهای کلیدزنی زیاد در مدارهای داخلی واحد تحت آزمون و افزایش توان خواهد شد. توان مصرفی بالا در زمان آزم...
'Hard-to-heal' wounds are those which fail to heal with standard therapy in an orderly and timely manner and may warrant the use of advanced treatments such as non-contact low-frequency ultrasound (NLFU) therapy. This evaluator-blinded, single-site, randomised controlled trial, compared NLFU in addition to UK standard of care [SOC: (NLFU + SOC)] three times a week, with SOC alone at least once ...
Quantifying soil organic carbon (SOC) decomposition under warming is critical to predict carbon-climate feedbacks. According to the substrate regulating principle, SOC decomposition would decrease as labile SOC declines under field warming, but observations of SOC decomposition under warming do not always support this prediction. This discrepancy could result from varying changes in SOC compone...
