1. Introduction. Magnesium phosphate cement (MPC) is a special cementitious material prepared by magnesia phosphate salt, chemical additive, and mineral admixture, which belongs to the magnesia cement and chemically bonded phosphate ceramics family, .The used magnesia is generally formed from high-temperature calcination of magnesite (MgCO 3) or dolomite …
Mix appropriate volumes of stock and add an equal volume of distilled water to make a final 0.1 M Sørensen's phosphate buffer solution (Sørensen, 1909; Gomori, 1955). Keep in mind that high levels of phosphate may be somewhat toxic to plant cells (Sabatini, et al., 1962) and thus Sørensen's buffer may not be appropriate for some experiments.

In parallel, we investigate citrate-stabilized nano-rock phosphate (nRP), and demonstrate that it possesses equivalent plant bioavailability as synthetic nHAP. Since nRP was prepared through simple mechanical grinding of mined and flotated rock phosphate, this underlines its potential for direct use in agriculture, provided that contact between ...

Ten test plants were immediately inoculated with 3 ml of the extract, and another 3 ml were layered on a Sephadex column. The rest of the extract was centrifuged at 128,000 g for 2 h. The resulting pellet was resuspended in 3 ml phosphate buffer and assayed on 8 to 12 test plants in the same way as each Sephadex fraction.
The fully mixed kinetic flotation model expressed in Eq. (12.34) has been used primarily in analysis of mechanical cells and flotation columns. Some of the newer cell designs aimed at increasing the flotation rate fall into a category that can be described as "reactor–separator" designs. A feature of the reactor part is a high concentration of bubbles.
The phosphate minerals in both types of ore are of the apatite group, of which the most commonly encountered variants are:-– Fluorapatite Ca10(PO4)6(F,OH)2 – Francolite Ca10(PO4)6–x(CO3)x(F,OH)2+x Fluorapatite predominates in igneous phosphate rocks and francolite predominates in sedimentary phosphate rocks.
The non-reducing sugar, sucrose, on the other hand, is a more stable compound and suitable for long-distance transport. For that reason, it has been found that the ratios of labeled hexoses to labeled sucrose decreased as the distance from the leaf assimilating 14 CO 2 increased.. Exudate analyses for nitrogenous compounds of willow stems have detected the presence of glutamic …
Streamflow and phosphorus concentrations were monitored in the Assabet River in central Massachusetts in order to evaluate concentrations and loads in the river before, during, and after changes in the amount of total phosphorus that was discharged to the river from three wastewater-treatment plants.
Phosphate Fertilizer. Phosphate fertilizer is good for acidic soils. Obtain organic phosphates or synthetic phosphate fertilizer depending on your needs. Bone meal is usually used to make organic phosphate fertilizer by grinding or steaming. Superphosphate is the chemical version of phosphate fertilizer.
The performance of a grinding circuit in the Esfordi phosphate mineral processing plant, located in Yazd Province, Iran was evaluated. For this purpose, samples from different units including i ...
Phosphorus (P) is one of the most important macronutrients necessary for the living organisms including plants. It is a vital constituent of several biological macromolecules like DNA, RNA and cell membrane, necessary for proper functioning of molecules like enzymes, ATP and NADPH etc., and essentially required for plant growth and development [].
Phosphofructokinase, with magnesium as a cofactor, changes fructose 6-phosphate into fructose 1,6-bisphosphate. Details: In the third step of glycolysis, fructose-6-phosphate is converted to fructose- 1,6-bisphosphate (FBP).Similar to the reaction that occurs in step 1 of glycolysis, a second molecule of ATP provides the phosphate group that is added …
