Nano-clean fracturing fluids have broad application potential in coalbed methane reservoir owing to their high stability, good temperature resistance, low filtration loss, and strong frictional resistance reduction. However, the sand-carrying regularity of nano-clean reservoirs is unclear, especially for complex fractures with variable directions. This study established a sand transport model t...

The development of pulmonary edema can be considered as a combination of alveolar flooding via increased fluid filtration, impaired alveolar-capillary barrier integrity, and disturbed resolution due to decreased alveolar fluid clearance. An important mechanism regulating alveolar fluid clearance is sodium transport across the alveolar epithelium. Transepithelial sodium transport is largely depe...

INTRODUCTION Fluid resuscitation in the critically ill often results in a positive fluid balance, potentially diluting the serum creatinine concentration and delaying diagnosis of acute kidney injury (AKI). METHODS Dilution during AKI was quantified by combining creatinine and volume kinetics to account for fluid type, and rates of fluid infusion and urine output. The model was refined using ...

Myocardial edema is a hallmark of ischemia-reperfusion-related cardiac injury. Ischemia-reperfusion has been shown to result in degradation of the endothelial glycocalyx. The glycocalyx is the gellike mesh of polysaccharide structures and absorped plasma proteins on the luminal side of the vasculature, and in the past decade has been shown to play an important role in protection of the vessel w...

Lymphatic fluid Swelling of the leg is a condition often seen in general practice. Most commonly it develops secondarily to a local abnormality in the venous or lymphatic system, but systemic abnormalities such as cardiac or renal failure or myxoedema should not be overlooked. By definition oedema is a pathological accumulation offluid in the interstitial tissues. Physiologists divide the body ...

Dissertation Research. My dissertation research centers on the investigation of a mathematical model of the feedback system that regulates the rate of filtration in nephrons. The nephron is the functional unit of the kidney; in the nephron, tubular fluid (nearly identical to blood plasma) is filtered out of the bloodstream and sodium chloride levels in the blood are maintained by the reabsorpti...

Glomerular and tubule functions were assessed by micropuncture in rats with extensive myocardial infarction produced by ligation of the left coronary artery 4 weeks prior to study. When compared to sham-operated control rats, rats with myocardial infarction involving 40 +/- 4% of the left ventricular circumference had lower mean arterial pressure (96 +/- 5 vs. 122 +/- 4 mm Hg, P less than 0.005...

Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum. The contributing mechanisms for the re...
