Using a novel, small sized, flow-through electrolytic module, (FEM), and a cost-effective saline solution, nascent oxidant biocides ( i.e. hypochlorous acid) can be produced for preventing and/or controlling micro-organisms that may plague aqueous polymer solutions in surface or downhole oil or gas well operations. The technology involves the use of electric current applied to the FEM while saline water is flowed through the two chambers of the FEM. A titanium tube plated with precious metals...
Aim of the experiment: Genistein, a phyto-estrogen, is mainly found in foods that consist of soybeans and/or soy protein. It is thought that genistein has antioxidant properties. However, in the past toxic effects have been indicated. The aim of the present experiment was to investigate the cytotoxicity of genistein by means of quantifying the cell viability of Chinese Hamster Ovary (CHO) cells after an 24 hours exposure to different concentrations of genistein. Principle: The viability of CHO...
Asthma is a considerable management issue for paramedics as every asthmatic patient is vulnerable of developing acute severe asthma. Asthma is a pulmonary emergency whereby; bronchial smooth muscle contraction and hypersecretion of mucous cause an airflow obstruction. McCance and Huether (2010) define asthma as a chronic disorder of the airways that involves a complex interaction of airway obstruction, bronchial hyper responsiveness and underlying inflammation. As a result of the inflammation,...
ABSTRACT: The usage of electric field with the anodic dissolution of metallic electrodes as activators and depressors at flotation ensures the electrochemical formation of the requested ions directly in the pulp. The electrochemical generated metallic ions have a bigger flotation activity, comparatively to the same metallic ions produced by the hydrolysis of suitable chemical reagents, because of their finer dispersion. The application of anodic dissolution of metallic electrodes is directly...
Highly ionized gases are good conductors of electricity. The motion of charge carriers in such gases produces electric and magnetic fields. The charged particles interact not only with the local fields but also respond to externally applied fields. When subjected to a static electric field, the charge carriers in the gas redistribute themselves in such a way that most of the gas is shielded from the field. The relatively field-free regions of the gas where positive and negative charges are...
The placebo effect is a contentious phenomenon especially in the health circles as it has over the years accumulated protagonists and antagonists alike with scientific interests growing by the day. Even with increasing interests in this phenomenon, misapprehension of what it is and its mode of operation is commonplace. A profound knowledge of how the placebo effect works plus its ethical implications are essential to utilise its relevant potentials for clinical and experimental benefits as...
In the food industry, rheological behavior and thermal degradation is the important parameters required to determine the quality and stability of food system. In this paper, the rheological behavior and thermal degradation of rice bran and corn oil, is investigated. Redwood viscometer is used to measure viscosity at a range of temperature. A 16F88 microcontroller based temperature controller is designed to measure and to keep the temperature of the oil at the desired temperature. The rice...
Cruel oil, another word is petroleum, is unprocessed oil, the thing which comes from the ground. Crude oil is a fossil fuel and was produced from decaying plants or animals living millions years ago in seas in nature, mostly in sea beds (EnergyAPI. 2009). Crude oils have different colour, ranging from clear to tar black. It has various viscosity as well, from water to almost solid. It is a very useful pioneer for many various substances as they have hydrocarbons. They are molecules that consist...
The aim of the present study was to compare the in vitro antibacterial activity of common root canal irrigants with a combination technique against intratubular Enterococcus faecalis.MethodsIn this experimental in vitro study, 75 single-rooted teeth were selected and their crowns and root-ends were dissected to obtain specimens with 5mm in length. Enterococcus faecalis strains were inoculated in the brain-heart infusion (BHI) medium and incubated for 21 days to contaminate the teeth. The...
About 60 of the worlds oil proven reserves is found only in carbonate reservoirs while 90 of these are observed to be neutral to oil-wet Akbar et al. 2001. Relating few factors such as reservoir heterogeneity, reservoir management, fluid type and drive mechanisms, experts observed that more than 50% of the oil trapped only in carbonate rocks is yet to be recovered (Sun and Sloan, 2003). Throughout the life cycle of the field, three stages of oil recovery are typically executed: Primary recovery...
