Molten salts have been widely used as energy storage materials in medium- and high-temperature thermal storage. However, pure salt commonly suffers from low conductivity many conventional methods of heat transfer enhancement do not apply due to the serious corrosion extremely high temperature. In current study, open-cell SiC ceramic foam was integrated with solar (60wt% NaNO3 + 40wt% KNO3) enha...

The ruminal selenomonad strain H18 grew rapidly (mu = 0.50 h-1) in a defined medium containing glucose, ammonia, purified amino acids, and sodium (95 mM); little if any ammonia was utilized as a nitrogen source. When the sodium salts were replaced by potassium salts (0.13 mM sodium), there was a small reduction in growth rate (mu = 0.34 h-1), and under these conditions greater than 95% of the c...

Goldschmidt, Millicent C. (University of Texas, Austin), and Orville Wyss. Chelation effects on Azotobacter cells and cysts. J. Bacteriol. 91:120-124. 1966.-Ethylenediaminetetraacetate (EDTA) is very toxic to Azotobacter in the presence of nitrogen compounds that form complexes with it. This appears to be due to stronger chelation of certain metal ions by the complex. When such complexes of EDT...

The COST wastewater treatment plant simulation benchmark is a useful example for evaluation of control strategies aiming at improving biological nitrogen removal. In the SMAC project, the phosphorus removal process, based on the ASM2d model, was added as an extension to the existing benchmark wastewater treatment plant. This results in an example for evaluation of control strategies for combine...

A new system for NH transfer is developed for the preparation of sulfoximines, which are emerging as valuable motifs for drug discovery. The protocol employs readily available sources of nitrogen without the requirement for either preactivation or for metal catalysts. Mixing ammonium salts with diacetoxyiodobenzene directly converts sulfoxides into sulfoximines. This report describes the first ...

The taxonomic nomenclature of Stelling-Dekker (1931) and Lodder (1934) is used throughout the paper. The yeast strains were derived partly from the stock of the Department of Bacteriology and Hygiene of the Hebrew University and partly from the following type culture collections: National Type Culture Collection, London; American Type Culture Collection, Washington; and the Centraalbureau voor ...

Soluble salts, nutrients, and pathogenic bacteria in feedlot-pen runoff have the potential to cause pollution of the environment. A 2-yr study (1998-1999) was conducted at a beef cattle (Bos taurus) feedlot in southern Alberta, Canada, to determine the effect of bedding material [barley (Hordeum vulgare L.) straw versus wood chips] and within-pen location on the chemical and bacterial propertie...

Two prevalent issues with Gastrodia elata growing in a natural wild environment are the necessary symbiotic seed germination Mycena spp. and long cycle of protocorms into mature rhizomes Armillaria mellea. This study explored most suitable nutrients to germinate seeds developmental stages propagated protocorm/juvenile (jrhs) through tissue culture approach. Adding humic acid, mashed potato, pep...
