the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...
The substantial interference of the tight reservoir's capillary pressure on relative permeability measurement can significantly diminish prediction accuracy oilfield production. This study established an innovative method to eliminate effect calculation by combining modified numerical simulation model and Genetic Algorithm. Steady-state measurements were conducted core sample (0.0321mD) obtain ...
This work compares several models for fluid flow through micropillar arrays to numerical simulations and uses them to optimize pillar dimensions for maximum fluid flow in a heat pipe application. Micropillar arrays are important for controlling capillary flow in microfluidic devices, and array permeability is a key parameter in determining fluid flow rate. Several permeability models are consid...
the prediction of porosity is achieved by using available core and log data; however, the estimationof permeability is limited to the scare core data. hence, porosity and saturation data through theframework of flow units can be used to make an estimation of reservoir permeability. the purposeof this study is to predict the permeability of a carbonate gas reservoir by using physical-basedempiri...
Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...
PURPOSE The accumulation of advanced glycation end products (AGEs) within the retina in diabetes is associated with a chronic increase in retinal microvascular permeability. Isolated perfused retinas were used to examine the acute effects of AGEs on retinal microvascular permeability. METHODS Retinas were dissected from eyes obtained from male Wistar rats, pinned out flat, and perfused with t...
Oleic acid induced pulmonary edema was subjected as an experimental model of ARDS. Three adult mongrel dogs were injected with 0. 09 ml/kg of oleic acid into the pulmonary artery and sacrificed 2 hours later. Light and electron microscopic studies were carried out on the pulmonary specimen. The light microsc9pic findings showed bronchovascular cuffs and alveolar flooding. The electron microscop...
Carbon dioxide has been used commercially to recover oil from reservoir by enhanced oil recovery technologies for over 40 years. Currently, the CO2 flood is the second most applied enhanced oil recovery (EOR) processes in the world behind steam flood. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. The...
