In heritage conservation, paper deterioration can be slowed down by controlling the environmental conditions surrounding objects and stabilizing materials these are made of. As conservation also cause optical, chemical, physical changes in object, their application should safe, minimalistic, purposeful. This aimed to observe functional applications of three biopolymers used conservation. For th...

In the present work, a new class of polymer composite is developed using walnut shell powder (WSP) as particulate filler in epoxy matrix. Three different sizes WSP are used for preparing three sets composites. The particle size selected 50-micron, 75-micron, and 100-micron. each set composites with size, four compositions i.e., 5 wt. %, 10 15 % 20 fabricated. All prepared have undergone testing...

Sunlight inactivation in fresh (river) water of fecal coliforms, enterococci, Escherichia coli, somatic coliphages, and F-RNA phages from waste stabilization pond (WSP) effluent was compared. Ten experiments were conducted outdoors in 300-liter chambers, held at 14C (mean river water temperature). Sunlight inactivation (k(S)) rates, as a function of cumulative global solar radiation (insolation...

The eubacterial genus Wolbachia comprises one of the most abundant groups of obligate intracellular bacteria, and it has a host range that spans the phyla Arthropoda and Nematoda. Here we developed a multilocus sequence typing (MLST) scheme as a universal genotyping tool for Wolbachia. Internal fragments of five ubiquitous genes (gatB, coxA, hcpA, fbpA, and ftsZ) were chosen, and primers that a...

This study investigated the effects of low levels of water-soluble pentosans (WSP), alkaline-extractable pentosans (AEP), and xylanase on the growth and organ development of broiler chicks. Three hundred and fifty 1-d-old female broiler chicks were randomly allocated into seven experimental groups of five pen replicates, with ten chicks per replicate. The control group consumed a corn-soybean m...

The petrochemical industry uses high volumes of water in its production processes and generates effluents that have a great potential for reuse processes. these is, therefore, an alternative the sustainable development sector. This study aimed at evaluating application ultrafiltration (UF) reverse osmosis (RO) treatment industrial water, reducing environmental impacts caused by disposal soil. e...

Both intrinsic and exogenous phytase in poultry feeds can alter phytate utilization and the solubility of P excreted. This experiment determined the effects of feeding diets varying in cereal grain, P concentration and phytase addition on phytate and P utilization and P characterization of ileal digesta and excreta. Twelve treatments, consisting of diets based on corn, wheat, barley, or high fa...

polyvinyl ester green composites were synthesized with walnut shell powder (wsp) by in-situ polymerization technique. the green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...
