Integration of the reverse-transcribed HIV cDNA into the host DNA is a required step in viral replication. The virus-encoded integrase protein catalyzes the initial DNA breaking and joining reactions that mediate cDNA integration. Here, the identification by X-ray crystallography of a small-molecule binding site on the integrase catalytic domain is reported. The small-molecule family studied co...

Biochar is a carbonaceous solid compound formed by high-temperature of organic waste. The quality biochar produced determined pyrolysis conditions and the type raw materials. This study focused on evaluation impact application soil chemical microbial properties. Four types from corn cobs, sawdust, mud press, rice hull were their composition (pH, Organic Matter, Carbon, Total Nitrogen, Carbon: N...

Arabidopsis thaliana root hairs grow longer and denser in response to low-phosphorus availability. We tested the hypothesis that wild-type Arabidopsis would acquire more phosphorus under phosphorus-limiting conditions than mutants that do not have the root hair response. The growth and phosphorus acquisition of wild-type Arabidopsis (WS) were compared to two root hair mutants (rhd6 and rhd2) un...

A nonmetal doping strategy was exploited for the conventional La0.5Sr0.5FeO3-δ (LSF) cathode, allowing high performance proton-conducting solid oxide fuel cells (H-SOFCs). Unlike previous studies focusing on utilization of metal oxides as dopants, phosphorus, which is a element, used cation dopant LSF by partially replacing Fe ions to form new La0.5Sr0.5Fe0.9P0.1O3-δ (LSFP) compound. The H-SOFC...

The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...

In this study, we determined the nutritional and functional characteristics of cookies supplemented with chichá almond, gurguéia nut, soursop residue using two developed cookie formulations one standard formulation. Acceptance purchase intention were evaluated. As almond 6 nut 2 sensorially viable, descriptive quantitative analysis, centesimal composition caloric value, mineral levels, microbio...

We tested the hypothesis that fate of dietary phosphorus will not differ among a dicalcium phosphate-free practical diet treated with 6-phytase (3000 FTU/kg; Quantum Blue™; P-F + Phy), and positive (C) negative (P-F) control diets when fed to hybrid tilapia (Oreochromis aureus x O. niloticus; 29.8 g initial weight) stocked at 29 fish/m3 grown for 5 months market size (454 g/fish) in outdoor bio...

In this paper, the chemical Functionalization of Carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. Phosphorus Ylides are important compound in organic chemistry. At first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...
