Discharge routing as a mathematic process to forecast the changes of greatness, speed and form of flood wave is function of time in one or more points along drainage, canal or reservoir. Hydrologic and hydraulic methods are used to accomplish the flood routing. Although hydrologic method is less accurate than hydraulic methods but it is simpler to use in flood control and designing works with...
The Moravian floods in July 1997 have killed 49 people, affected 536 settlements, 29 000 houses and cost over 2.5 billion USD. A question arises whether the hydrological event (or the preceding meteorological one) can be predicted. In order to foresee the magnitude of catastrophic events we extrapolate historical data which has an impact on the construction in the vicinity of the rivers, insura...
OBJECTIVES The objective of this study was to determine the nuances of management, prognostic factors, and outcome of ischemic priapism in patients seen at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. PATIENTS AND METHODS We retrospectively studied the case notes of all patients managed for ischemic priapism in the Ahmadu Bello University Teaching Hospital, Zaria, over a period ...
Since the most important climatic parameter affecting sugar beet cultivation is the temperature, we carried out this research considering climatic elements such as temperature, precipitation and freezing days in relation to autumn sugar beet planting. Daily temperatures of selected stations in a period of 10 years (2005-2015) has been used for agroclimatic analysis. In order to evaluate that, t...
osteoporosis (op) is a frequent complication of rheumatoid arthritis (ra) and longitudinal studies have documented increased rate of bone loss in ra patients. to determine the frequency of low bone mass as well as the influence of disease duration and corticosteroid use on bone mass in patients with ra, 88 patients with ra and 112 age matched controls were studied. bone densitometry was perform...
Given the importance of climate change issue, consideration of the climate and hydrological data trend has become very important. This study aimed to evaluate the effectiveness of different methods to remove the effect of autocorrelation in assessing the trend of parameters such as temperature, precipitation and discharge of the Eastern Gorganrood Basin, Golestan Province. For this purpose, in ...
This report contains terrestrial absolute gravity measurements performed near the village of Kulusuk in southeast Greenland. It represents an exceptionally long time series nearly two decades. The began July 1996 until 2015. station is located a few meters beside permanent GNSS station. final values (g-values), more precisely accelerations due to gravity, are listed along their associated uncer...
Solar Radiation Estimation from Rainfall and Temperature Data in Arid and Semi-arid Climates of Iran
Precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. Therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. This paper is about an evaluation of eight models foran estimation of daily solar radiation (Q) from ...
BACKGROUND Plasma exchange (PEX) treatment for patients with thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) has risk for major complications. STUDY DESIGN AND METHODS Data for PEX-related complications have been prospectively collected on all patients enrolled in the Oklahoma TTP-HUS Registry, 1996 to 2011. PEX-related complications have been defined as major or minor...
