The study investigated the nutritional, mineral Anti-nutritional factors, molar ratios and antioxidants compositions in the leaves of four selected wild edible vegetables (Piper guinensis, Piper umbelatum, Celosia argentia and Jatropha tajorensis) collected in Ado Ekiti, Ekiti State, Nigeria. The proximate, minerals and anti-nutrient compositions of the samples were determined using standard procedures. Also antioxidant activity of the samples were detected using standard assays such as 1, 1, diphenyl-2-2 picrylhydrazyl (DDPH) and Ferric Reducing Antioxidant Potential (FRAP).The mineral ratio,

The fruit of the cherry tomato ( Lycopersicon esculentum (Solanaceae)) was analysed for mineral and antinutrient composition. Phosphorus (33.04 ± 0.21 mg/100g) was the most abundant mineral in the fruit, followed by calcium (32.04 ± 0.06 mg/100g), and potassium (11.9 ± 0.1 mg/100g) and manganese (9.55 ± 0.28 mg/100g) were also present in appreciable quantities. Antinutrients, including phytate, glycoside, saponin and tannin, were screened and quantified. Phytate (112.82 ± 0.1 mg/100g), glycoside (2.33 ± 0.00 mg/100g), saponin (1.31 ± 0.00 mg/100g) and tannin (0.21 ± 0.00 mg/100g) were present

The successful production of unconventional reservoirs through hydraulic fracturing is heavily dependent on the brittleness of the shale's. To precisely evaluate rock brittleness the mineral-based brittleness indices are considered reliable. Initially, only the weight fraction of quartz accounted for mineralogical brittleness, later dolomite was included in the group, further, it was divided into the silicate and carbonate groups. Due to its heterogeneous nature, shales contain some other minerals, however, the impact of these minerals on rock brittleness has yet to be analyzed. The mineral py

Abstract:

There is evidence that differences in either maternal blood pH or dietary mineral content can result in alterations in secondary sex ratio in mammals. Altering the proportions of certain dietary minerals is known to influence blood pH, offering a possible explanation for this effect of diet on secondary sex ratio. The present study was performed to investigate whether altering blood pH by manipulating the dietary cation–anion difference (DCAD) would alter secondary sex ratio. The DCAD is calculated (in mEq per 100 g dry matter) as the difference between metabolically strong cations (Na + K) an

Abstract:

Even though ground geophysical surveys (especially Induced polarization and resistivity) are applied in mineral exploration, their effectiveness in identification of mineralised zones is often enhanced by integrating other mineral exploration techniques such as remote sensing and geological investigations. Integrating different techniques helps in reducing uncertainty that is often associated with mineral exploration. The methods being integrated also depend on characteristics of mineralisation and those of host rock. In this study, geophysical survey methods (induced polarization and resistiv

Abstract:

Grass tetany is a common metabolic disorder of ruminants in southern Australia. To investigate the genetic control of mineral concentrations leading to this disorder, replicate populations of perennial ryegrass half-sib families were grown at Hamilton and Timboon in southern Australia. Variation in herbage yield, and Mg, P, K, Ca, Na, Cl, S, Mn, Fe, Cu, Zn, and K/(Mg+Ca) (tetany ratio) concentrations in the herbage of these families was measured in the early spring of 1994. Large environmental effects on herbage mineral concentration were detected, with location differences accounting for 60–8

Only six silicate-based commercial minerals are officially called ‘asbestos’. However, currently, to be counted as asbestos, a fiber also must be long enough to be seen with light m

The paucity of reliable experimental data, as well as the absence of any other documented occurrences of such a mineral in over 80 years, led to the supposition of a typographic error in the transcription of the original chemical analysis, suggesting the mineral might in fact be nickelskutterudite [(Ni,Co,Fe)As3]. As a consequence, the mineral was discredited and deleted in the post-2006 IMA list of valid mineral species. Nonethel

This is due to the very complex nature of the hydrochemical conditions, and uranium-isotopic methods are used to clarify these conditions.

A better understanding of the nature and properties of OMA will help predict the fate of oil spilled in the aquatic environment. This work describes the various instruments and methods currently
