The dissolution of gypsum and calcium carbonate from high-pH soils during extraction may have released excess Ca (Doann, 2006b). Lower %BS of low-pH soils is logically related to exchangeable acidity. 4.4 Cost analysis and efficiency. The higher cost of ICP-MS was compensated for by cost of duplicate ICP-OES measurements (Table S4). Thus ...

When faced with a plethora of issues, the possibility of one problem becoming the solution of another is a rare, yet beneficial scenario. This report explores the prospect of viewing the accumulation of organic waste matter in India as a potential calcium reservoir to relieve the issue of calcium deficiency in the population. Waste generation has seen gradual growth, and …

The calcium extraction efficiencies were 96% and 38% for 0–50 μm and 74–125 μm particle fractions, respectively. The effect of sonication can be used to break the silica gel production layer, formed in pores during the extraction of calcium. However, the feasibility of ultrasound should be studied further, as it uses a significant amount ...

Oxalates react with calcium to precipitate calcium oxalate and accumulation of oxalates in the body prevents the absorption and utilization of calcium; which in turn causes calcium imbalance ...

Most metals are found as types of rock in the Earth's crust. These ores contain sufficient minerals with important elements including metals that can be economically extracted from the rock.

Common bean is the most important major food legume which is used either as a source of protein for local consumption or as an export crop for income generating in Ethiopia.

Using the common extraction protocols, only one of the two phases can be extracted, while the other one is degraded. In the present work a method of extraction which allows the obtainment of both proteins and calcium phosphates was developed. Bones from two different species (salmon and sea bream) were tested.

Background Phosphorus (P) availability is commonly assumed to limit productivity in many tropical soils, yet there is relatively little information on the phosphorus chemical forms, distribution, and transformations that P undergoes in Ethiopian soils. We used a sequential fractionation scheme to assess phosphorus fractions of acid soils of Southern Ethiopia. The …

Ethiopia, reports the results of laboratory tests made on a range of the materials, and gives details of an investigation of an existing cinder gravel road. With the aid of aerial …

Ethiopia is already the sixth biggest producer of tantalum in the world with the potential to dramatically increase their standing. Adola in southern Ethiopia is the most exciting region for tantalum.

Development of calcium supplements from calcium-rich waste material has the potential to not only reduce the strain on waste management, but also to provide the calcium-deficient population with a cheaper alternative to traditional supplements. When faced with a plethora of issues, the possibility of one problem becoming the solution of another is a rare, …

The electrolyzers used to extract calcium from copper-calcium alloys at 0.5 to 3.0 kA were designed, manufactured, and utilized to study the process parameters more precisely. The pilot electrolysis device used to produce calcium from copper-calcium alloys at 12 to 15 kA was developed. The calcium production using the bipolar electrolyzer was proved to be …

High calcium content tuber crop of Ethiopia Yosef Yambo1 and Tileye Feyissa1,2* 1 Department of Agriculture, College of Veterinary Medicine and Agriculture, Addis Ababa University, P.O. Box 1176, Addis Ababa, Ethiopia. 2 Institute of Biotechnology, Addis Ababa University, P.O. Box 1176, Addis Ababa, Ethiopia.

On the other hand, if the ion-pair extraction is the dominant mechanism, calcium extraction efficiency can be improved in [N 4444][DEHP] due to the stronger interaction between [N 4444] + and Cl‾ than that of [P 4444] + and Cl‾ in the organic phase. Meanwhile, the presence of methylbenzene diluent can also lead the extraction mechanism from ...

Techniques for Extraction, Isolation, and Standardization of Bioactive Compounds from Medicinal Plants. ... Drying is the most common method to preserve the plant material from enzymatic .

Calcium deficiency is common among Chinese people, especially children and the elderly (Huang et al., 2018). People ... As taking calcium extraction rate as the evaluation index,

Ethiopian Minerals Ethiopia is indeed the land of plenty, with resources found in abundance throughout its huge and diverse land mass. Geological surveys conducted on minerals in Ethiopia, have shown formations that are believed to contain a vast amount of mineral resources, with proven deposits of industrial minerals, coal, precious metals and metals.

Teff (Eragrostis tef (Zucc.) Trotter) is among the most widely cultivated staple cereal crops in Ethiopia and its grains are rich in starch. Ethiopia is the largest teff producer in the world and teff straw (TS) is the solid waste byproduct. Traditionally, TS is used as a binding material for muddy walls of huts and fodder for livestock [8, 9].Enset (Ensete ventricosum (Welw.)

In Ethiopia, feed industries are widely using limestone as a cheap source of Ca without adequate information on the bioavailability of its Ca content and the presence of other …

The existing methods for extracting individual neural activity from microendoscopic data can be divided into two classes: semi-manual ROI analysis (Barbera et al., 2016; Klaus et al., 2017; Pinto and Dan, 2015) and PCA/ICA analysis (Mukamel et al., 2009).Unfortunately, both approaches have well-known flaws (Resendez et al., 2016).For example, ROI analysis does …

The role of calcium (Ca) in the cycle of phosphorus in water environment depends on the speciation of Ca in sediments, and reliable Ca sequential extraction method is useful for obtaining information about Ca transport processes from sediment to water. Experiments have been carried out to develop a simple but robust Ca sequential extraction method for …

Representative staple foods from Sidama, Southern Ethiopia, were analyzed for phytate using HPLC, and for Zn, Fe and Ca by flame atomic absorption spectrophotometry …

(mostly iron, calcium, phosphorus, and copper) than other cereal grains, contain B1vitamin and is rich in fiber [3, 6]. The physical appearance of teff grain is hull-less (naked) and comes during a range of colors from milky-white to just about dark brown. The foremost common colors are white, creamy-white, brown, and dark brown.

As a typical food waste, bone waste is always disposed of in landfills or incineration or used to make products with low added values. In contrast, extracting calcium phosphate micro/nanoparticles from bone wastes is a feasible method of valorization. However, the bones previously used for extracting Ca-P micro/nano particles are limited to fresh bones …
