background and aims. several products have been marketed for disinfecting impression materials. the present study evaluated the effect of deconex, micro 10, alprocid and unisepta plus sprays on staphylococcus aureus and candida albicans transferred to alginate and polyvinylsiloxane impression materials. materials and methods. a total of 180 impressions of a maxillary model (90 alginate and 90 p...

in this study the effect of diet dilution in 16-20 d of age and using a multi-enzyme (endofeed-w) on performance, carcass characteristics and some blood parameters of broiler chickens (cobb 500, commercial strain) was studied. this experiment was conducted as a factorial arrangement 2×3 in a completely randomized design with 3 replicates and 8 chicks in each replicate. experimental diets contai...

This study was conducted to evaluate the effects of replacing maize in quail diets with graded levels of rumen filtrate-fermented cassava meal (FCM) on growth and egg production performances. Cassava meal (CM) was mixed with dried manure of layer at 75 g/kg CM, which was mixed with freshly collected rumen filtrate (at 1 L/5 kg CM), and finally fermented in sealed bags for 14 days. It was then s...

We report a spray deposition technique as a screening tool for solution processed solar cells. A dual-feed spray nozzle is introduced to deposit donor and acceptor materials separately and to form blended films on substrates in situ. Using a differential pump system with a motorised spray nozzle, the effect of film thickness, solution flow rates and the blend ratio of donor and acceptor materia...

An experiment was conducted to evaluate the effects of feeding laying hens grains naturally contaminated with a combination of Fusarium mycotoxins. Parameters measured included performance, organ weights, and plasma chemistry. One hundred and forty-four, 45-wk-old laying hens were fed diets including: (1) control, (2) contaminated grains, and (3) contaminated grains + 0.2% polymeric glucomannan...

The effects of Selko-pH (S; 1 mL/L drinking water); Termin-8 (T; 2 kg/ton feed) and Neogermicin (N; 2 L/ton feed) on gastrointestinal tract (GIT) pH, microbial population, ileal digestibility and broiler performance were investigated. The lowest feed intake (FI) was attained by chickens fed diets supplemented with S group in all periods (P

Cleaning and Disinfecting  The efficacy of most disinfectants against SVV is not clearly known.  Because vesicular diseases are clinically indistinguishable, disinfection protocols for FMDV should be followed even if SVV is suspected. This includes use of: sodium hydroxide, sodium carbonate, 0.2% citric acid, aldehydes, and oxidizing disinfectants including sodium hypochlorite.  Below are EP...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

an 84-day feeding trial was carried out onfingerling (4.44 ± 0.06 g) rainbow trout (oncorhynchusmykiss, walbaum, 1792) to evaluate the effect of dietary supplementation with a commercial prebiotic grobiotic®-a (g-a) on the growth, feed efficiency, haematology and immunlogical parameters. ttreatments containing various inclusions of g-a (0 %, 0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %) were ad...
