The efficacy of gliding arc (GA) discharge for the generation of hydrogen peroxide (H2O2) and water with a low pH was studied because H2O2 combined with low-pH environment is known as a strong oxidizer that can be used for the bacterial inactivation. The ability of the GA discharge to inactivate Escherichia coli in water was tested experimentally, and the inactivation was found to increase with...

OBJECTIVES To assess trends in intussusception and to validate the coding in Hong Kong's computerised discharge information system. DESIGN Case notes were reviewed for all children under the age of 5 years who had a discharge diagnosis indicating intussusception or a procedure indicating reduction of intussusception during the 6-year period 1 July 1997 through 30 June 2003. RESULTS Intussus...

Allen, Shih-Hsien Tseng, Kerry Swanson, Mary Ann McClay Industrial & Systems Engineering, The Ohio State University, Columbus, Ohio President of St. Mary’s Janesville Hospital, Janesville, Wisconsin Process Excellence Black Belt, Sagata Ltd., Columbus, Ohio ABSTRACT This article describes the application of a five-phase Six Sigma define, measure, analyze, improve, and control (DMAIC...

This paper presents the development of the low cost liquid pump. The rotary compressor developed as the gas compressor for the residential air-conditioner was converted into the liquid refrigerant pump. Problems of the liquid refrigerant pump are the reliability assessment of sliding parts and the reduction of the noise generated by discharge pulsation in this development. Therefore some modifi...

The soluble lead-acid battery is a redox flow cell that uses a single reservoir to store the electrolyte and does not require a microporous separator or membrane, allowing a simpler design and a substantial reduction in cost. In this paper, a transient model for a reversible, lead-acid flow battery incorporating mass and charge transport and surface electrode reactions is developed. The charge–...

Pollutants discharged from stormwater pipes can cause water quality and ecosystem problems in coastal bayous. A study was conducted to characterize sediment and nutrients discharged by small and large (< 20 cm and >20 cm in internal diameters, respectively) pipes under different rainfall intensities (< 2.54 cm and > 2.54 cm, respectively). Results showed that large pipes had greater discharge t...

Conventional graphitic anodes in lithium-ion batteries cannot provide high-power densities due to slow diffusivity of lithium ions in the bulk electrode material. Here we report photoflash and laser-reduced free-standing graphene paper as high-rate capable anodes for lithium-ion batteries. Photothermal reduction of graphene oxide yields an expanded structure with micrometer-scale pores, cracks,...

Objective: To evaluate the mandatory folic acid fortification of flour on mortality rates after the hospital discharge of children born with myelomeningocele, the most affected age group and the most frequent cause of death. Methods: A retrospective study of 383 children born with myelomeningocele from January 1990 to December 2013 in a high-fetal-risk reference hospital. Results: A total o...

This retrospective cohort analysis of Medicaid claims data included .30 000 children from 12 states who were hospitalized for asthma from 2005 to 2007. The study linked hospitalization for asthma and readmission for asthma with b-agonist medication fill rate, oral steroid fill rate, and inhaled steroid fill rate. Readmission was defined as hospitalization with a primary or secondary diagnosis o...

This study uses a vector autoregression (VAR) model to analyze changes in pollutants among different mining industries and related policy in China from 2001 to 2014. The results show that: (1) because the pertinence of standards for mining waste water and waste gas emissions are not strong and because the maximum permissible discharge pollutant concentrations in these standards are too high, am...
