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

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.

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%.

Abstract:

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

Abstract:

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

In this study, sodium perchlorate (NaClO4) was selected as the primary salt in TMP-based electrolytes. While this combin

Waste cockle shells containing abundance of nearly pure calcium carbonate (CaCO3) are ideal sources of calcium. In this study, the waste cockle shells were turned to CaO nanoparticles using a simple chemical route.

Hydroxyapatite (HAp) is a biomaterial containing calcium phosphate with the chemical formula which is similar to the structure of human bone, so it is good for the purpose of healing human bones and teeth.

However, the discussion about the difference of HAp results with the mixing method of ultrasonic machine and magnetic stirrer is still rarely done.
