The development of the health sector to search alternatife material bone’s repair is increasing. Bone is a natural composite containing 60% minerals, 30% matrix, and 10% water. The component of bone mineral is calcium phosphate. Tricalcium phosphate is the type of calcium phospate that used because it has chemical component’s as like bone’s component. In this study, white mussel shell was chosen as a source of calcium and H3PO4 as a solvent. The aim of this research was determining reaction kinetics of tricalcium phospate synthesis from white mussel shells. The research was started by dissolvi

Acidity is still a serious obstacle for maize cultivation due to the very low availability of phosphorus. The use of phosphate biofertilizers, containing phosphate solubilizing bacteria as an active ingredient, together with organic ameliorants was expected to be able to provide phosphorus for plants and increase the organic C content in the soil. Experiment aimed to find the proper application of phosphate biofertilizers along with organic ameliorants to support the productivity of maize on acid soils.

To understand more fully the role of the in vivo turtle shell in buffering lactic acid produced during prolonged anoxia, powdered turtle shell was incubated in vitro at constant pH (6.0, 6.5, 7.0, 7. 5 or 8.0) in electrolyte solutions simulating extracellular fluid. Exchanges of ions and CO2 between the shell and solution were evaluated by measuring pre- and post-incubation solution concentrations of calcium, magnesium, sodium, potassium, chloride, phosphate and lactate. The production of CO2 from the shell and lactate within the shell were also measured. We observed that calcium and magnesium

A study has been conducted on the possibility of obtaining fertilizers with controlled nitrogen release by applying a non-organic digestible shell of monocalcium phosphate to granules of nitrogen-containing mineral NPK and NP(S) fertilizers. It is shown that the structure of the obtained granules has a clearly defined core and the protective shell itself. The study of granules by fractions showed that the applied monocalcium phosphate shell is evenly distributed over the entire surface of the pellet, regardless of the fraction, and the maximum deviation of the actual shell thickness from the c

RNA molecules cannot fold in the absence of counterions. Experiments are typically performed in the presence of monovalent and divalent cations. How to treat the impact of a solution containing a mixture of both ion types on RNA folding has remained a challenging problem for decades. By exploiting the large concentration difference between divalent and monovalent ions used in experiments, we develop a theory based on the reference interaction site model (RISM), which allows us to treat divalent cations explicitly while keeping the implicit screening effect due to monovalent ions.

Mobergellans are a distinctive group of Lower Cambrian breviconic shells with a prominent set of internal scars, presumably representing sites of former muscle attachment. Shells grew by accretion and appear to have secreted primary phosphate.

Hippoklosma mongolica (Missarzhevsky) is bilaterally symmetrical, with five pairs of radiating structures. These are presumably homologous with the muscle scars of other mobergellans, but in contr

Phosphorus is an essential nutrient for aquatic plants and animals. The acceptable range for phosphorus in water is from 0.01 to 0.03 mg/L. However, excessive phosphorus use can result in biodiversity loss and pollution and endanger aquatic creatures and human health because the pollutants are non-biodegradable and thus accumulate over time. This work investigated the removal of phosphorus from synthetic wastewater containing KH2PO4 via adsorption using calcined cockle shell waste.

Abstract The article presents the results of a study of NPK and NPS fertilizers effectiveness, as well as urea, on the granules surface of which a coating based on monocalcium phosphate with a thickness of 100 microns was applied. The use of nitrogen-containing fertilizers provided an increase in the yield of spring wheat grain by 31-46%, while the yield when using coated fertilizers was 9-10% higher compared to conventional fertilizers. The shell of the granules contributed to a more complete use of nutrients by plants, and the nitrogen use efficiency increased from 40-49% to 47-59%.

At the present stage of development of plant virology the study of molecular mechanisms of regulation, translation and replication of viral RNA is of great interest. Potato virus X (PVX) RNA in viral particles is not available for in vitro translation, but acquires the ability to be translated as a result of shell protein phosphorylation. The aim of our study was to investigate the conditions of phosphorylation of the PVX coat protein in in vitro and in vivo systems, as well as the effect of EDTA and CaCl2 on the phosphorylation in vitro. Methods. The PVX coat protein was obtained by the guani

ABSTRACT The core of the VP-1 and VP-2 proteins forming the T=1 icosahedral capsid of the prototype strain of the parvovirus minute virus of mice (MVMp) share amino acids sequence and a common three-dimensional structure; however, the roles of these polypeptides in the virus infection cycle differ. To gain insights into this paradox, the nature, distribution, and biological significance of MVMp particle phosphorylation was investigated. The VP-1 and VP-2 proteins isolated from purified empty capsids and from virions containing DNA harbored phosphoserine and phosphothreonine amino acids, which

Scallop-shell powder (SSP) heated at high temperature exhibits high pH and broad antimicrobial activity. Bioshell calcium oxide (BiSCaO) is an SSP composed mainly of calcium oxide. It is poorly water-soluble under alkaline conditions and the generated precipitate can plug spray nozzles. The aim of this study was to establish that BiSCaO dispersion caused no significant CaO loss and plugging of spray nozzles, and to evaluate its deodorization and microbicidal abilities and its ability to reduce the concentrations of NO2− and NO3−. BiSCaO dispersions were prepared by mixing various concentration
