Current trends in ward flooring materials and cleaning methods are considered from the point of view of the hospital bacteriologist. Methods employed in an investigation into the bacteriological safety of a number of floor-cleaning machines are described, and some considerations governing the choice of vacuum cleaners for ward use are discussed.

A producer survey that included 885 facilities was conducted to assessthe associationsbetween preweaning mortality and various facility attributes. Using univariate analysisand a multiple regression model, we found a signiffcant association between preweaning mortality and flooring type, heat source, water delivery system,cleaning frequency,cleaning method, and duration of idle time between far...

the major objectives of this study were to find out the mechanism behind the sapstaining fungal hyphae penetration into wood elements using electron microscope and to evaluate the exact role of phenolic compounds existing in wood vinegar towards the sapstaining fungal growth inhibition. to formulate the new environmental friendly wood preservative, we neutralized (to ph 7) wood vinegar with nao...

hemicellulose of southern yellow pine wood spices was extracted by pressurized hot water at three different temperatures: 140°c, 155°c and 170°c. compounding with pp (polypropylene) was performed by extrusion after preparing wood flour and sieving to determine its mesh size. the ratio of wood to polymer was 50:50 based on oven-dry weight of wood flour. all extraction treatments and control samp...

Illegal logging, felling and timber trade have continued to increase over the past two decades, leading a decline in forest biodiversity extinction of some wood species. Pterocarpus indicus Willd., listed National Standards People’s Republic China for Hongmu (GB/T 18107-2017), is widely used production high-end furniture, decorative flooring musical instruments due its high-quality timbe...

Vertebral fractures are relatively common in elderly patients and these are most frequently associated with falls from a standing height or less [1]. In a backward fall, floor forces at impact are known to decrease with a decrease in floor stiffness, which suggests a possible strategy for injury prevention [2], however the effects on spine forces are unknown. The objectives of this study were t...

to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...

The Rn and Rn enter the atmosphere mainly by crossing the air interface of either soil-air or building materials. The existence of relatively high indoor concentration maintains a large Rn, Rn concentration gradient between the materials and open air. The present paper deals with the experimental measurement of Rn, Rn concentrations and the associated inhalation dose rates due to them in the dw...

3 Paragraph 4, lines 3 and 4, p. 2911: For the following sentence citing reference [60], units should be in μg/(m h); not in mg/(m h). On an area basis, caulking has the highest emission rate, 310 μg m h, among materials tested, followed by carpet pads (installed underneath carpets), 2.1 to 9.9 μg m h. Emission rates fell below 1 μg m h for other materials tested, which included solid and engin...
