Research ArticleOpen accessEvery word in the titleNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproving Effects of Different Calcium-Magnesium Conditioners on LatosolJin Li, Yingbin Xue, Minzhong Chen et al.At present, soil acidification seriously restricts the sustainable development of agricultural production. A common method that can be used to improve acidified soils is to apply calcareous materials (conditioners), but there is difference in the improvement effect of the conditioners on the same soil because of the conditioners containing different calcium-magnesium compounds. In order to find suitable conditioners for latosol … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 13 Oct 2020 · 6,626 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTotal Conductivity of Calcium Iron Borate Glasses Using an Empirical FormulaHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeySamples of calcium borate glasses containing iron ions have been prepared with three different concentrations of both boron and iron oxides. X-ray diffraction spectroscopy was performed and results revealed that samples are in good glassy state, with high homogeneity and short range ordered structure. Electrical conductivity was experimentally measured in the temperature range from 300 to 553 K. Conductivity results … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 21 May 2019 · 7,096 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Golden Red Sodium Calcium Silicate GlassesWang Cheng-Yu, Wun Nuan-Xin, Ge Yi et al.Traditional golden red glasses were based on K2O-PbO-SiO2 composition system. In this paper, we reported new golden red glasses based on Na2O-CaO-SiO2 system without SnO2 and PbO in them. By using a spectrophotometer and chromamter color difference meter, it was found that the new glasses had similar optical properties to the traditional ones. The diameter of the gold particles in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 13 Feb 2019 · 7,061 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,978 accessesView PDFCite

Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution when the waste is discarded into rivers. In order to add value to SW, a study was conducted to produce potassium and calcium hydroxide, compost and Humic Acid (HA) from SW. Approach: The SW was air-dried and some grinded. The grinded SW was incinerated at … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,583 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAmphetamine Stimulates Protein Kinase and Calcium Influx to Increase Corticosterone and Aldosterone Secretion from Male Rat Adrenal CellsLing-Ling Chang, Wan-Song Alfred Wun, Cai-Yun Jian, Paulus S. WangAmphetamine is a potent central nervous system stimulant. Clinical trials have demonstrated that in healthy adults, low (therapeutic) doses of amphetamine can improve i.e., cognition, memory, attention behavior. An amphetamine overdose can affect cardiovascular, central nervous system, musculoskeletal, respiratory, urinary, or sexual function. Furthermore, amphetamine can activate the hypothalamic-pituitary-adrenal axis to increase glucocorticoids and mineralocorticoids released from adrenal.
