Microbicidal activity of neutrophils is usually measured by colony-counting techniques after cell lysis in distilled water. While studying the effect of the reduced nicotinamide adenine dinucleotide phosphate-oxidase inhibitor diphenyleneiodonium (DPI) on the staphylocidal activity of neutrophils, we obtained inconsistent results: various degrees of inhibition in some experiments and no effect ...

expansive soils are considered a worldwide problem as they cause extensive damage tocivil engineering structures. an important characteristic of expansive soils is theirsusceptibility to volume change due to the phenomenon of wetting and drying. this paperpresets the effect of pore water quality on the swelling and shrinkage behavior of anexpansive soil during wetting and drying cycles. thirty ...

Topographically heterogeneous agricultural landscapes can complicate and accelerate agrochemical contamination of streams due to rapid transport of water and chemicals to poorly drained lower-landscape positions and shallow ground water. In the semiarid Palouse region, large parts of these landscapes have been tile drained to enhance crop yield. From 2000-2004 we monitored the discharge of a ti...

BACKGROUND In Japan, the effects of reduced water, such as hydrogen-rich electrolyzed reduced water and natural reduced water, like Hita Tenryosui water®, have been examined. The purpose of the present study was to identify the role of natural reduced water in anxiety and blood biochemical analysis. MATERIALS AND METHODS Natural reduced water and distilled water were administered to rats for ...

A pure sodium chloride solution, at the concentration in which this salt exists in sea-water, may be poisonous to marine organisms, as was first proven by Loeb,’ who found that the young of a marine fish (Fundulus) soon die in y to F solution of sodium chloride. That death is due to the poisonous action of the sodium chloride, and not merely to the absence of other constituents of the sea-water...

Edible coatings (EC) with mucilage of Opuntia ficus-indica or Aloe arborescens are promising to extend the shelf life fresh-cut fruit products by reducing weight loss and microbial spoilage. In this work, kiwifruits (cv. Hayward) were coated in solutions extracted from (MC) A. (AL). We used three alternative treatments AL MC, MC+AL, distilled water as control, stored passive atmosphere at 5 °C ...

Environmentally friendly anaerobic digestion (AD) of lignocellulose-based materials is becoming an increasingly popular alternative to non-renewable energy sources. It also corresponds with the principles sustainable development. The structure lignocellulosic materials, which resistant biodegradation, requires using pretreatment methods prior subjecting them processes. aim study was evaluate in...
