particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...

The world coffee consumption has been growing for its appreciated taste and its beneficial effects on health. The residual biomass of coffee, originated in the food industry after oil extraction from coffee beans, called coffee beans residual press cake, has attracted interest as a source of compounds with antioxidant activity. This study investigated the chemical composition of aqueous extract...

I in the chain sow diet --> blood serum of sow --> sow milk --> piglet serum was investigated in two experiments with a total of eighty-one sows and their piglets. In experiments conducted during the last trimester of gravidity and the 28 d of lactation, diets with glucosinolates (1.9 mmol/kg diet via 100 g ground rapeseed/kg diet (Expt 1) and 2.1 and 4.2 mmol/kg diet via 75 and 150 g rapeseed ...

Until now it has not been possible to separate fermenting activity from living yeast cells; the following describes a procedure that solves this problem. One thousand grams of brewer’s yeast1 that had been cleaned as a prerequisite for the preparation of compressed yeast, but to which no potato starch had been added, is carefully mixed with the same weight of quartz sand2 and 250 g Kieselguhr. ...

Polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. In this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. Polyanionic cellulose nanoparticles are made by using of ball milling. Size of nanoparticles is measured by Particle size analyzer. Polyani...

The aim of this study consisted of manufacturing renewable binderless fiberboards from coriander straw and a deoiled coriander press cake, thus at the same time ensuring the valorization of crop residues and process by-products. The press cake acted as a natural binder inside the boards owing to the thermoplastic behavior of its protein fraction during thermopressing. The influence of different...

cmc polymer is used as an additive to decrease water loss and mud-cake-thickness in mud drilling. in this study, the effect of cmc and cmc nanoparticles on water loss and mud-cake-thickness in mud drilling is investigated. cmc nanoparticles are made by using of ball milling and their size is measured by particle size analyzer. cmc and cmc nanoparticles which were prepared by hamilton batch mixe...

A standard performance testing protocol for mechanical manure solids separators has been developed and tested. The protocol measures separator press-liquor throughput and dry-mass capture efficiency across a range of input total solids (TS) concentrations. This protocol was used to test two commercially available screw-press manure solids separators, a Vincent KP-6L and a PressTech Agri-Press w...

Sacha inchi (Plukenetia Volubilis L.) was originally cultivated in Amazon rainforest Peru. seeds have high nutritional value (oil 35-40%, protein 25-30%...) [1], therefore, they are considered a “superfood”. oil contains unsaturated fatty acids (omega 3, 6, 9) that humans cannot synthesise on their own. However, the extraction process produces large number of by-products (70% nut shells and pre...
