The biological sulfide removal from wastewater caustic streams can be achieved without significant dilution by alkaliphilic microorganisms which usually show lower growth and oxidation rates as compared with acidic and neutral bacteria. To improve volumetric removal rates under alkaline condition (pH 10), an Alkaliphilic Sulfide-oxidizing Bacteria Consortium (ASBC) was studied in a Packed Recyc...

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

To The Editor: To elucidate the mechanism of granulocyte damage during FL, studies have been reported of the interaction between nylon-wool fibers and isolated granulocytes suspended in protein free media,’2 in 5% plasma,2 or in 1% human serum albumin.3 In FL, however, heparinized whole blood is passed through a nylon-wool filter, resulting in plasma protein coating of the fibers within seconds...

Abstract Wafers of Tb-doped GdAlO 3 / ? -Al 2 O eutectic were fabricated by the micro-pulling-down method using an Ir crucible with a 25 × mm die. A prototype X-ray phase imaging detector was developed CMOS sensor fiber optic plate and wafer. spots 8.24 ? m period observed detector. nylon ball diameter 4 also carried out. It that change approximately occurs at air–nylon interface. This techniqu...

Post-consumer carpet represents a high volume, high energy content waste stream. As a fuel for co-firing in cement kilns, waste carpet, like waste tires, has potential advantages. Technological challenges to be addressed include assessing potential emissions, in particular NO emissions (from nylon fiber carpets), and optimizing the carpet feed system. This paper addresses the former. Results of...

The surface characteristics of various carbon and graphite fibers and the Interfaclal region between fibers and resin In composites were Investlgaced by using electron microscopy, electron diffraction and Raman spectroscopy. The latter technique permits differentiation between graphite fibers of different origin. Graphite fiber composites were prepared by in situ polymerization on nylon 6. This...

The evaluation of foodstuffs provides the animal nutritionists with necessary information to adjust the diet from a physiological and economic point of view, so that the animal performance be desirable. Nowadays, there are various methods for evaluating ruminant feed intake. One of the most important methods is in situ nylon bag technique. Prosopis farcta is one of plants which is used as forag...
