abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

Microorganisms play important roles in phosphorus (P) cycling via their regulation of P uptake and transport, mineralization solubilization, the mediation deficiency forest biomes. However, dynamics microbial functional genes underlying regulatory mechanisms different biomes (e.g., temperate vs. subtropical) have yet to be sufficiently clarified. In this study, we applied a metagenomics approac...

This paper proposes a low power EHC that performs synchronous energy conversion on a tri-plate variable capacitor to improve the maximum achievable power. A tri-plate macro electrostatic generator with capacitor variation of 405 pF to 1.15 nF and 405 pF to 1.07 nF on two complementary adjacent capacitors operating 180° out of phase at 98 Hz is fabricated and used in the characterization of the ...

Phosphorus (P) is one of the major essential macronutrient for plant growth. Phosphate solubilizing bacteria (PCB) is a group of heterotrophic bacteria capable of solubilizing organic and inorganic phosphorus from insoluble compounds, releasing phosphate available for plant uptake. In this study endophytic bacteria were isolated form nodules of French bean grown in different intercropping syste...

The title compound, C21H23NSi, was synthesized by Sonogashira-type reaction of 1-ethyl-3-iodo-2-phenyl-1H-indole with tri-methyl-silyl-acetyl-ene. The indole ring system is nearly planar [maximum atomic deviation = 0.0244 (15) Å] and is oriented at a dihedral angle of 51.48 (4)° with respect to the phenyl ring. The supramolecular aggregation is completed by weak C-H⋯π inter-actions of the methy...

The effect of trialkyllead and trialkyltin on pig erythrocyte hemolysis has been studied and compared. The results of experiments showed that the hemolytic activity of organoleads increases with their hydrophobicity and follows the sequence: triethyllead chloride < tri-n-propyllead chloride < tributyllead chloride. And similarly in the case of organotins: triethyltin chloride < tri-n-propyltin ...
