Transmission lines located in the desert are subjected to desert climate, one of whose features is sandstorms. With long accumulation of sand and with the advent of moisture from rain, ambient humidity and dew, a conductive layer forms and the subsequent leakage current may lead to surface discharge, which may shorten the insulator life or lead to flashover thus interrupting the power supply. S...

A 57-year-old man was admitted because of abdominal pain and vomiting; he had a history of right inguinal hernia and type 1 diabetes mellitus. Physical examination revealed mild abdominal distention, no incision scar, abdominal tenderness, minimal bowel sounds, a tender and bruised scrotum, and an irreducible hernia. Abdominal radiography revealed abnormal small intestinal air fluid levels, and...

The Zinc-air primary batteries (ZAB’s) are prone to electrolyte leakage upon exposure high temperature and humidity conditions. Potassium hydroxide is a hygroscopic corrosive compound it can cause various electrochemical corrosion failures for the attached electronics inside device. In this study, effect of humid conditions on from three different Zinc Air Battery variants were investigated. ex...

The industry of hermetic compressors for domestic refrigeration have been continuously studying ways to increase the performance of its products, with the aim of reducing the demand of electric energy and so contribute for a lower environmental damage in the future. One of the systems in which focus is put on during the compressor development, is the suction and discharge manifold. Such focus i...

BACKGROUND Pituitary adenoma, craniopharyngioma and meningioma are common sellar lesions, accounting for more than 90% of sellar tumors. The aim of this study is to assess the reliability and safety of the lateral supraorbital (LSO) approach to remove sellar tumors. METHODS Between June 2011 and December 2011, 23 patients with neoplastic lesions underwent surgery by the corresponding author (...

PD morbidity and readmission pose a substantial clinical and economic burden to the healthcare system. Comprehensive PD complications and readmission data are essential for developing initiatives to improve patient care. No previous studies have extensively investigated PD complications after gastric cancer surgery.We investigated the incidence, types, treatment, and risk factors of 30-day post...

OBJECTIVE To assess the medical and psychosocial effects of early hospital discharge after surgery for breast cancer on complication rate, patient satisfaction, and psychosocial outcomes. DESIGN Randomised trial comparing discharge from hospital 4 days after surgery (with drain in situ) with discharge after drain removal (mean 9 days in hospital). Psychosocial measurements performed before su...

Abstract Erhai Lake is a highland freshwater lake in Dali, China. Rapid tourism development has generated large amounts of pollutants. Since 2015, six wastewater treatment plants (WWTPs) have been built to treat collected through sewage interception projects. In this study, reductions the pollution load from different sources were evaluated by considering effects groundwater leakage, microbial ...

The aim of this study is the presentation results an in-lab comparative electrical and thermal monitoring artificially polluted, HTV-textured silicone rubber insulators, with different pollution levels. This work a preliminary in-situ 400 kV SiR textured in polluted environment. showed that rms leakage current magnitude pulses, average dissipated power depended on levels dry-bands formation. di...

leakage in water distribution networks causes waste of water and economical losses. in this paper a new method is presented to calculate nodal and pipes leakage in water distribution systems using capabilities of epanet2.10 software. the method estimate the total water losses in the system based on iwa methodology using minimum night flow (mnf) measurements. recognising the pressure dependency ...
