Basics of Clay Minerals and Their Characteristic Properties

open access: yesClay and Clay Minerals [Working Title], 2021
Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source.

Complete genome sequencing and comparative genomic analyses of Bacillus sp. S3, a novel hyper Sb(III)-oxidizing bacterium

open access: yesBMC Microbiology, 2020
Background Antimonite [Sb(III)]-oxidizing bacterium has great potential in the environmental bioremediation of Sb-polluted sites. Bacillus sp. S3 that was previously isolated from antimony-contaminated soil displayed high Sb(III) resistance and Sb(III ...

Mixed Double-Ranked Set Sampling

open access: yesRevstat Statistical Journal, 2021
A new modification of ranked set sampling (RSS) is investigated to estimate the mean of the study population. This modified approach is a double-stage approach and a kind of combination between RSS and median RSS (MRSS).

A Bayesian optimization approach to the extraction of intrinsic physical parameters from T2 relaxation responses [PDF]

open access: yesE3S Web of Conferences, 2023
NMR transverse relaxation responses in porous media provide a sensitive probe of the micro-structure yet are influenced by a set of factors which are not easily detangled. Low-field T2 transverse relaxation measurements can be carried out quickly and are

Evaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids.

Porosity in minerals

open access: yesAIMS Materials Science, 2021
<abstract> <p>Minerals typically form porous assemblies with porosity extending from a few percent to ca. 35% in porous sandstones, and over 50% in tuff, clays, and tuff. While transport of gases and liquids are widely researched in these materials, much less is known about their mechanical behaviour under stress. With the development of

Electric spring average model development and dynamic analysis for demand-side management

open access: yesIET Smart Grid, 2019
This study proposes a new averaged model for steady-state and dynamic response analysis of the electric spring (ES). The accuracy of steady-state and dynamic behaviour of the ES is demonstrated.

Mineral Acquisition from Clay by Budongo Forest Chimpanzees [PDF]

open access: yes, 2015
Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations.

Role of Minerals and Trace Elements in Diabetes and Insulin Resistance

open access: yesNutrients, 2020
Minerals and trace elements are micronutrients that are essential to the human body but present only in traceable amounts. Nonetheless, they exhibit well-defined biochemical functions.
