The growth of two robust algae strains Chlorella sp. and Scenedesmus sp. growing in Lithuanian lakes was investigated with the aim to obtain optimum conditions for biomass cultivation for biofuel production in the Lithuanian environment. Samples were taken from different nitrogen sources and of different concentrations, with addition of various concentrations of CO2 and in the presence of salt....

The nutritional requirements of Shigella grown in chemically defined media have been investigated by Koser et at. (1938a, b), Kligler and Grosowitz (1939), and Weil and Black (1944), among others. These investigators have reported the successful cultivation of various strains of Shigella in chemically defined, synthetic media of variable composition. All of these media consisted of inorganic sa...

The synthesis and properties of an oxygen reduction catalyst based on a unique 3-dimensional (3D) nitrogen doped (N-doped) carbon composite are described. The composite material is synthesised via a two-step hydrothermal and pyrolysis method using bio-source low-cost materials of galactose and melamine. Firstly, the use of iron salts and galactose to hydrothermally produceiron oxide (Fe₂O₃) mag...

Chemical studies of the blood and urine of four dogs following pyloric obstruction are reported. The observations of other workers that a fall in chlorides and a rise in CO(2)-combining power of the plasma occur, are confirmed. There is also a marked rise in the non-protein nitrogen of the blood, consisting mainly of urea nitrogen and undetermined nitrogen. The fall in chlorides is not due to t...

The effect of long-term soil phosphorus (P) on in situ nitrous oxide (N2O) emissions from temperate grassland ecosystems is not well understood. Grasslands typically receive large nitrogen (N) inputs both animal deposition and fertiliser application, with a proportion this N being lost to the environment. Understanding optimum nutrient stoichiometry by applying fertilisers relative balance P wi...

The use of lactose as inducer for the expression of dextransucrase was investigated in high density of Escherichia coli. Different culture conditions including carbon source, nitrogen sources, inorganic salts, inoculum density (OD 600 ) and lactose concentrations were optimized, and high-level expression of dextransucrase in E. coli was achieved via an optimal culture conditions. The results in...

KNO3 was used as the phase change material (PCM), but its thermal conductivity is too low to transfer heat between the PCM and conduction oil efficiently. In this thesis, on the basis of the previous studies (Yong Li, 2015), the solar power generation efficiency is enhanced with high temperature interval (280°C—400°C), and the new composite which are composed by the SiC honeycomb (SCH) frame an...

The objective of this study was to evaluate the utilization of different sources of unsaturated long-chain fatty acids in diets for dairy cows during the transition period and early lactation on the milk fatty acid profile and composition of the protein fraction. Thirty-six Holstein cows were divided into three groups, fed the following diets: control (C); soybean oil (SO); and calcium salts of...

The present study identifies and characterizes a novel ATP-dependent bile-salt transport system in isolated canalicular rat liver plasma-membrane (cLPM) vesicles. ATP (1-5 mM) stimulated taurocholate uptake into cLPM vesicles between 6- and 8-fold above equilibrium uptake values (overshoot) and above values for incubations in the absence of ATP. The ATP-dependent portion of taurocholate uptake ...

Oxidation of 3,4-ethylenedithio-3'-iodo-tetrathiafulvalene (EDT-TTF-I) and 3,4-ethylenedithio-3',4'-diiodo-tetrathiafulvalene (EDT-TTF-I2) with DDQ afforded two different salts formulated as (EDT-TTF-I)(DDQ) and (EDT-TTF-I2)2(DDQ)·(CH3CN), both characterized with a full charge transfer to the DDQ acceptor moiety and by short and linear halogen bonding interactions between the iodine atom as hal...
