Abstract (sommario):
Fouling characteristics of reverse osmosis (RO) membrane with chemical coagulation and microfiltration (MF) pre-treatment were investigated at full-scale leachate treatment systems. In chemical coagulation pre-treatment, solid separation from stabilized leachate was performed by ferric chloride coagulation followed by sand filtration. Meanwhile, MF pre-treatment and the RO system utilized direct filtration using a 0.03 µm membrane without chemical addition. MF pre-treatment yielded better pollutant removals in terms of organics and nitrogen. The study on effect of pre-treatment on RO membrane

Abstract (sommario):
This work aims to investigate removal efficiency of oxidation and coagulation/flocculation processes, to provide an effective method for the treatment of biologically pre-treated leachate. Leachate containing 985 mg L−1 COD was treated by using three treatment schemes, i.e. oxidation, coagulation/flocculation and the combined process of coagulation/flocculation followed by oxidation. The application of single oxidation resulted in the effective removal of COD and color up to 80.4 and 83.2%, respectively. However, residual COD values lower than 200 mg L−1 could only be achieved under intensive

Abstract (sommario):
Landfill leachate is considered as a complex wastewater with various organic and inorganic species which must meet strict discharge standards before its release. Due to such high concentration of diverse pollutants, leachate is low in biodegradation; therefore, a proper usage of physicochemical treatments is required. In this study, membrane distillation (MD) has been used along with Fenton treatment process for pre-coagulation to achieve an effective removal of contaminants. MD is a technology derived with vapor pressure difference across the hydrophobic membrane which traps the feed-wastewat

Thesis (MScFoodSc)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Large volumes of high strength wastewater are generated annually by distilleries. Treatment of this wastewater is essential to increase its reuse potential. Anaerobic digestion (AD) has been widely applied as high strength wastewater treatment. Additionally, grain distillery wastewater (GDWW) is high in fats, oils and grease (FOG) which can cause problems during AD. Pre-treatment is therefore often required to make the AD process more efficient. The overall objective of this study was to investigate the operational effici

Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations.  The three most common analyses, platelets count, haemoglobin and prothrombin time were tested.  Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result.

Coagulation has and continues to be one of the most important elements in medicine. Issues from a lack of hemostasis range from poorer clinical outcomes to sudden death. The evolution of treatments for hemostasis have evolved from the use of Tamponade with direct pressure and bandages, the use of materials such as cobwebs and dust, the use of heat with hot oil or heated irons, to the use of suture, glues, plasmas, staplers, and electricity. This evolution has continued to bring about the prophylactic use of technology in an effort to prevent blood loss. This change from reactive treatments

Abstract (sommario):
Elevated serum progesterone levels stimulate respiratory drive and lead to an increased tidal volume and raised minute ventilation, with only a modest increase in O<sub>2</sub> consumption. Any cause of maternal hypercapnia leads quickly to foetal respiratory acidosis. Elevation of the diaphragm occurs due to the enlarging uterus, leading to a reduced functional residual capacity (FRC). Raised levels of coagulation factors and impaired fibrinolysis, combined with venous stasis, result in a significantly increased risk of venous thromboembolism (VTE). Upper airway oedema, particularly in the setting of pre-eclampsia, may predispose to upper airway obstruction during sleep, but rarely frank OSA. OSA tends to occur in obese women and may be associated with impaired foetal growth and pre-eclampsia. Snoring in pregnancy is a poor predictor of OSA.

Abstract (sommario):
Hemostasis in patients presenting for liver transplantation is characterized by a reduction in both pro- and anticoagulant factors. Blood loss is due to multiple factors but usually a consequence of pre-existing abnormalities of the hemostatic system, portal hypertension with multiple collateral vessels, portal vein thrombosis, previous abdominal surgery, splenomegaly, and poor functional recovery of the new liver. The intrinsic coagulopathic features of end-stage cirrhosis along with surgical technical difficulties make transfusion-free liver transplantation a major challenge, and, despite the improvements in understanding of intraoperative coagulation profiles and strategies to control blood loss, the requirements for blood or blood products remains high. The impact of blood transfusion has been shown to be significant and independent of other well-known predictors of post-transplant outcome.

Abstract (sommario):
In normal pregnancy the arterial pressure falls in the second half of the first trimester: systolic pressure then remains unchanged throughout pregnancy, with diastolic pressure tending to rise gradually towards its prepregnancy level in the later weeks. Definitions, epidemiology and clinical features—(1) Pregnancy-induced hypertension (PIH), transient hypertension of pregnancy, or gestational hypertension describe new hypertension, defined as blood pressure equal to or in excess of 140/90 mmHg, which without proteinuria affects up to 10% of women after mid term (20 weeks) and resolves after delivery. (2) Pre-eclampsia, which affects 3 to 5% of pregnancies, is defined by the presence of PIH and pregnancy-induced proteinuria arising after 20 weeks gestation that both improve after delivery. Other features include (a) renal insufficiency; (b) hepatocellular dysfunction and/or severe epigastric/right upper quadrant pain; (c) neurological problems—convulsions (eclampsia), severe headaches, persistent scotomata; (d) haematological disturbances—thrombocytopenia, disseminated intravascular coagulation, haemolysis; (e) fetal growth restriction....

This discrepancy is more pronounced in assays of higher purity Factor IX (FIX) or Factor X (FX) concentrates. We have found that addition of a mixture of bovine albumin (0.1% w/v) and Tween 20 (0.01% v/v) (BAT) to the dilution buffer can eliminate the discrepancy, giving clotting
