The deterioration of drinking water during distribution process is caused by many factors. The microorganisms and substances peeling off from the “growth-ring” make the secondary pollution in drinking water distribution systems. To reduce the secondary pollution, two-phase pulse flushing technology is introduced to quickly remove the “growth-ring”. In this study, experiment is undertaken for in...

The article presents the results of analysis deep deformations Amu Darya riverbed in upper reaches low-pressure reservoir. combined transverse profiles different sections Takhiatash reservoir showed that coastal zones are most intensively silted up. At same time, core zone with highest flow rates is very weakly declared. height silting layer along length stream increases direction dam. area ext...

Urban catchments in sub-Saharan Africa (SSA) are increasingly becoming a major source of phosphorus (P) to downstream ecosystems. This is primarily due to large inputs of untreated wastewater to urban drainage channels, especially in informal settlements (or slums). However, the processes governing the fate of P in these catchments are largely unknown. In this study, these processes are investi...

this study aims at investigating the effectiveness of utilizing barley as a flushing ration with an energizing source and soybean meal-based diets as a flushing ration with a protein source the sexual and breeding behaviors in ghezel sheep. to this end, 36 three and half-year old ewes (51±1.5 kilograms) with the record of giving birth to two lambs and 6 three-year old (89±2.5 kilograms) rams we...

this study investigated the effect of dietary supplementation with calcium salts of fatty acids using 48 afshari ewes randomly allocated to four treatments. all groups used in flushing period and only the source of energy were different between rations. the ewes were divided into four groups: a-barely grain; group b-received 5% of csfa with source of flaxseed oil (w3); group c-received 5% of cs...

During a control infusion noradrenaline and alcohol each provoked carcinoid flushing in four of five patients and pentagastrin in two of five patients. When tetradecapeptide somatostatin was infused on another day no patient flushed at any time, even when 16 microgram of either noradrenaline or pentagastrin were administered. Carcinoid flushing was not associated with release of gastrin or any ...

BACKGROUND The purpose of this study was to examine the relationship between cardiovascular disease risk and alcohol consumption according to facial flushing after drinking among Korean men. METHODS The subjects were 1,817 Korean men (non-drinker group, 283 men; drinking-related facial flushing group, 662 men; non-flushing group, 872 men) >30 years who had undergone comprehensive health exami...

BACKGROUND The purpose of this study was to examine whether facial flushing after drinking influences the relationship between alcohol consumption and prostatic hyperplasia among Korean men. METHODS The subjects were 957 Korean men (180 non-drinkers, 389 with drinking-related facial flushing, 388 without facial flushing) in the 40-69 age group, who underwent prostate ultrasound at the health ...

Arsenic (As) fractions in the sediments of seven lakes from East Plain Ecoregion and six lakes from Yungui Plateau Ecoregion, China, were investigated. Results indicated that the total As concentrations in sediment samples of lakes of the East Plain Lake Ecoregion are higher than those of Yungui Plateau Lake Ecoregion. Residual As is the main fraction in sediment samples of lakes from both ecor...

BACKGROUND The aim of the present study is to evaluate the risk of metabolic syndrome (MS) according to alcohol consumption for those subjects showing facial flushing, as well as the absence of facial flushing. METHODS One thousand two hundred and one males were recruited in the health promotion center of a university hospital. Evaluation of alcohol consumption and facial flushing was assesse...
