Magnesium phosphate cements (MPC) are the most developed kind of chemically bonded ceramics which form through the reaction of magnesium oxide and soluble phosphate salts. Therefore, study of different magnesium phosphate cement systems is considered important according to the type of phosphate agent used. In this study, effect of mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), and ...
The purpose of this study was to evaluate the spatial changes of groundwater phosphate concentrations using geostatistical methods based on data from 10 groundwater wells. One of the conventional tools in decision making on the groundwater management is geostatistical method. To evaluate the spatial changes of phosphate concentrations in groundwater, the universal kriging method with cross-vali...
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....
in order to study and compare the phosphate transporter gene codon usage and it's respond to the traits like salt tolerance, day length, pollination and temperature in different plants, 100 isoform from 10 plants are extracted from ncbi website and then analyzed with gene infinity and minitab 16 software. the result shows that the highest codon usage similarity (81.95%) was for wheat and oryza ...
Background & Objective: The presence of nitrate and phosphate in concentrations above the allowable level in surface and groundwater resources leads to disease and problems. The aim of this study was to investigate the adsorption efficiency of magnetic-metallic chitosan nanocomposite in the adsorption of nitrate and phosphate from aqueous solutions. Materials and methods: The adsorbent was synt...
Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
ABSTRACT-The enrichment of bedding for vermicomposting systems with organic and inorganic additives is a technique which can promote the quality of produced vermicompost. Phosphate rock and fishmeal are two available and low-cost substances which can be provided easily and inoculation of vermicompost with phosphate solubilizing microorganisms (PSMs) can enhance the availability...
Due to the excessive use of chemical fertilizers and also the lack of adequate information on the growth responses of ornamental plants to bio-fertilizers and municipal solid waste compost, this investigation was carried out on Zinnia. Therefore, a field experiment was conducted in complete randomized block design with three replications. Fertilizers included municipal solid waste compost, phos...
