This paper presents a detailed analysis of underwater electrical discharge parameters in the treatment chromium (VI) used as model pollutant to analyze reduction process by plasma liquid interaction (PLI). Pin-to-pin microsecond discharges were performed an aqueous Cr(VI) solution and processes characterized using measurements, optical imaging UV-Vis absorption measurements for [Cr(VI)] estimat...

BACKGROUND Evidence to date suggests that capnography monitoring during gastrointestinal endoscopic procedures (GEP) reduces the incidence of hypoxemia, but the association of capnography monitoring with the incidence of other adverse outcomes surrounding these procedures has not been well studied. Our aims were to estimate the incidence of pharmacological rescue events and death at discharge f...

Background and Objectives: Discharge against medical advice (DAMA) is a significant healthcare problem posing negative impact on effectiveness of patient care and costs of the health system. In order to address this problem, first the potential influencing factor should be identifies. This study followed two major objectives: first, to evaluate the prevalence and potential causes of DAMA, and s...

This paper is about experimental results for partial reduction of vortex at vertical pipe intakes. One of the easiest and practical ways of reducing vortex effect is to use anti-vortex plates or baffles. These plates can be used to avoid the vortex completely or partially. This paper will concentrate on the latter case. Rectangular plates with different dimensions have been placed at different ...

Background Ageing has become a serious challenge in Hong Kong and globally. It has serious implications for health expenditure, which accounts for nearly 20% of overall government expenditure. Here we assess the contribution of ageing and related factors to hospitalisation days in Hong Kong. We used hospital discharge data from all publicly funded hospitals in Hong Kong between 2001 and 2012.  ...

impact of effluent discharge from aquaculture facilities is a growing concern among policy makers. Since 1974, the United States Environmental Protection Agency (EPA) has regulated discharge of pollutants to waters of the United States under authority of the National Pollutant Discharge Elimination System (NPDES) permit. In some states, the NPDES permits have been applied to effluents from aqua...

The microbicidal effect of electrical discharges on microorganisms suspended in the discharge liquid was reduced when the liquid contained high concentrations of inorganic salts (conductivity k >/= 5 mmho/cm). A higher discharge voltage and a smaller distance between the submerged electrodes counteracted this reduction. The decrease in the microbicidal effect was accompanied by a change in the ...
