Crystalline structure of CaO-P2O5-SiO2 system at 3,000 K were investigated by molecular dynamic simulation. The models with different concentrations P2O5 (5-40 mol%) constructed using Born-Mayer-Huggins potentials. size was from 5,270-5,520 atoms. local environment elements and glassy-network in detail. radial distribution functions (RDFs) showed that the average first nearest neighbor distance...

Indonesia is the second most biodiverse country after Brazil in Latin America. However, fisheries sector, can be called first richest country. There are approximately 2,000 species of fish found Indonesian waters. Dumbo catfish (Clarias gariepinus) one type freshwater that busy being cultivated by people Indonesia, especially province East Java, Bangkok Village, Gurah District, Kediri Regency. ...

in order to investigate the response of coneflower to applying chemical fertilizer and incorporation with municipal solid waste compost (mswc), a pot experiment was conducted as completely randomized design with six treatments included: control (without applying chemical fertilizer and compost), chemical fertilizer (150 kg n, 120 kg p2o5 and 250 kg k2o per hectare from urea, triple super phosph...

Developmental exposure of Long-Evans rats to 0, 1, 4, or 8 mg/kg/day Aroclor 1254 (A1254) from Gestational Day 6 through Postnatal Day 21 produces an elevated behavioral threshold for a 1-kHz tone. Brainstem auditory evoked responses (BAERs) were assessed in a subset of these animals (about 1 year old) using filtered clicks at 1 (65 and 80 dB SPL), 4 (60 and 80 dB SPL), 16 (40 and 80 dB SPL), a...

evaluating potential influenza virus inhibitors. However, the viral strains traditionally used in these models are fairly old and do not represent currently circulating viruses in nature. We developed two new lethal infection models in mice using mouse-adapted influenza A/New Caledonia/ 20/99 (H1N1) and influenza B/Sichuan/379/99 viruses. Both virus infections were used to study oral treatment ...

Class I and III polyhydroxyalkanoate (PHA) synthases catalyze the conversion of beta-hydroxybutyryl coenzyme A (HBCoA) to polyhydroxybutyrate. The Class I PHA synthase from Ralstonia eutropha has been purified by numerous labs with reported specific activities that vary between 1 and 160 U/mg. An N-terminal (His)6-PHA synthase was constructed and purified with specific activity of 40 U/mg. The ...

Total treatments were 14 with three replications in randomized block design. treatment consist @ 30, 45, 60 kg ha-1 presence Thiobacillus thiooxidens, as elemental along recommended dose fertilizer (110:40:60 N, P2O5 & K2O + 15 t FYM). application RDF S thi...

Bu çalışmada tarla koşullarında farklı mikoriza türleri aşılamasına ve fosfor doz uygulamalarına bağlı olarak dolmalık biber bitkisinin gelişimi üzerindeki etkisinin belirlenmesi amaçlanmıştır. Denemede G. mosseae etunicatum türleri, Fosfor (P) dozları ise fosforsuz ( P0= 0 kg P2O5/ha) fosforlu (P1= 80 uygulama yapılmıştır. Çalışma 1998 1999 yıllarında iki yıl üst üste olacak şekilde yürütülmüş...

BACKGROUND Retroviral-mediated gene transfer stably introduces exogenous genes into normal and neoplastic cells of the hematopoietic system. METHODS We used two retroviral vectors [the first, FLac, expresses a chimeric protein (Sh-ble::LacZ) between the product of the phleomycin resistance gene (Sh-ble) and the bacterial beta-galactosidase encoded by the LacZ gene; the second, NuNL vector, co...

Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical bioplastic production. Six bacterial strains were isolated and identified as Bacillus cereus (KF270349), ...
