امروزه معضل افزایش فرسایش بادی و طوفان های گردوخاک بعلت تغیرات اقلیمی و خشکسالی های متوالی به بحرانی منطقه ای جهانی تبدیل شده است. برای منشأیابی، پیش بینی شدت و گستردگی و سرعت انتقال این طوفان ها از روش های مختلفی همچون مدل های عددی، تصاویر ماهواره ای و تحلیل های همدیدی استفاده می شود. در این مطالعه با بررسی و تحلیل نقشه های فشاری سطوح مختلف جوی، به اثر پارامترهای دما، فشار و سرعت باد در سطوح م...
Energy is the key mover for any country’s development. In today’s era, demand energy rapidly increasing and cost of power also due to lack fossil fuels (coal, gas, oil). To overcome worst crises non-renewable resources, present solution move towards renewable energy. Sindh a province Pakistan that has immense capability prospect neat green production. The major locations resources are found in ...
OBJECTIVES To find out if the presence of the metabolic syndrome increases the risk of subsequent total and cardiovascular mortality, taking into account established risk factors for cardiovascular disease. DESIGN Prospective cohort study. SETTING General population. PARTICIPANTS A community based sample of 2322 men followed since 1970 for a maximum of 32.7 years, investigated at ages 50 ...
[1] Near-surface wind speeds (u) measured by terrestrial anemometers show declines (a ‘stilling’) at a range of midlatitude sites, but two gridded u datasets (a NCEP/NCAR reanalysis output and a surface-pressure-based u model) have not reproduced the stilling observed at Australian stations. We developed Australia-wide 0.01 resolution daily u grids by interpolating measurements from an expanded...
The performance of single models and ensemble prediction systems has been investigated with respect to quantitative precipitation forecasts. Evaluation is based on the potential economic value of +72 h/+96 h forecasts. The verification procedure consists of taking into account all precipitation amounts that are predicted in the vicinity of an observation in order to compute spatial, multi-event...
INTRODUCTION Metabolic syndrome (MetSyn) as defined by the latest Harmonised definition and the agreement between the Harmonised definition and other definitions is poorly studied among Malaysians. This study was conducted to determine and compare the prevalence of MetSyn according to the Harmonised, International Diabetes Federation (IDF) and National Cholesterol Education Program (NCEP ATPIII...
BACKGROUND The American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), revising the National Cholesterol Evaluation Program for Adult Treatment Panel III (NCEP ATP III), and the International Diabetes Federation (IDF) have proposed definitions of metabolic syndrome that take into account waist circumference thresholds according to ethnicity. In this study we estimated ...
OBJECTIVE The International Diabetes Federation (IDF) has proposed a new definition of the metabolic syndrome that emphasizes central adiposity as determined by ethnic group-specific thresholds of waist circumference. The objective of this study was to estimate the prevalence of this syndrome using the IDF definition among U.S. adults and to compare it with the prevalence estimated using the de...
