BACKGROUND AND PURPOSE Attempts have been made to associate intracranial aneurysmal hemodynamics with aneurysm growth and rupture status. Hemodynamics in aneurysms is traditionally determined with computational fluid dynamics by using generalized inflow boundary conditions in a parent artery. Recently, patient-specific inflow boundary conditions are being implemented more frequently. Our purpos...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Groundwater from the coastal aquifers north of Chennai is being pumped since 1981 to meet the increasing demand. Huge groundwater extracting in the coastal aquifers groundwater causes lowering of groundwater table which led to seawater intrusion. The objective of this study is to assess the behavior of this aquifer to seawater intrusion under different hydrological stresses by groundwater model...

Abstract The pollution of heavy metals in irrigation water was related to the management-control risk farmland and safe production crops. There were various sources suburb farmlands Xijiang River. We investigated distribution characteristics on a riverside inside-dyke According sample test results, it found that nearly 100% we concerned about detected study. box plot showed average content othe...

The paper aims to examine the impact of financial sanctions on capital inflow and outflow in Iran. The research question is about examining the effect of financial sanctions on FDI inflow and capital outflow in Iran. We used the intervention model as an econometric method to estimate the impact during 2005-2019. The paper discussed three periods. From 2005 to 2010, severe financial sanctions ne...

The rate of inflow to a long well can vary along its completion length, e.g. due to frictional pressure losses or reservoir heterogeneity. These variations often negatively affect the oil sweep efficiency and the ultimate oil recovery. Inflow Control Devices (ICDs) represent a mature well completion technology which provides uniformity of the inflow profile by restricting high specific inflow s...

In the process of in situ mining underground oil shale, it is necessary to build an frozen wall around area prevent inflow groundwater and gas leakage. However, water saturation soil affects formation freezing circle. practical engineering, when building a under different conditions, curtain often not closed. It also construction operating costs entire project. this paper, methods laboratory ex...

Despite modeling groundwater as a common property resource, existing economic analyses find that the quantitative difference between competitive and socially optimal groundwater management outcomes is negligible. Thus, in contrast to the public perception of groundwater overextraction and resource depletion, there appears to be no economic rationale for groundwater management. In this paper, we...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

Hongjiannao groundwater exchange was the largest desert freshwater lake in China (57.25 km2 1986). However, it shrank sharply over past 34a (1986–2019), with smallest area 31.41 2015. The objective of this study to use Landsat images, ASTER GDEM V2 data, and meteorology statistics combination water balance model calculate dynamics elements, quantify characterize interannual variations lake-grou...
