Abstract Barite concrete composite materials have been investigated for 252 Cf spontaneous neutron and 60 Co/ 192 Ir gamma sources’ shielding using Monte Carlo computational method. The Particle Heavy Ion Transport code System (PHITS) was used to compute the properties of three different (barite concrete, barite cement, aggregate) as structural walls in fixed & industrial radiography Non-De...

Abstract The Niederschlag fluorite-barite vein deposit in the Western Erzgebirge, Germany, has been actively mined since 2013. We present results of a first comprehensive study mineralogy, petrography, fluid inclusions, and trace element geochemistry fluorite related to deposit. Two different stages mineralization are recognized. Stage I is older, fine-grained, associated with quartz, forms com...

A series of basic carboxamides of actagardine (1), a lantibiotic possessing good antistreptococcal activity, were synthetized. Some physico-chemical characteristics, in particular charge and lipophilicity, that influence water solubility were determined. The in vitro and in vivo activity was evaluated. The monocarboxamides were generally more active than actagardine against selected Gram-positi...

the extended hildebrand solubility parameter approach (ehsa) is used to estimate the solubility of satranidazole in binary solvent systems. the solubility of satranidazole in various water-peg 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of hildebrand-scatchard treatment for regular solutions. the solubility equation employs term interaction energy ...

Barite stands out as one of the most ubiquitous scaling agents in deep geothermal systems, responsible for irreversible efficiency loss. Due to complex parameter interplay, it is imperative utilise numerical simulations investigate temporal and spatial precipitation effects. A one-dimensional reactive transport model set up with heterogeneous nucleation crystal growth kinetics. In line systems ...

The properties of a variety of mouth protectors and sheet materials used to fabricate custom mouth protectors were determined in order to recommend limits for a specification. Hardness, water sorption, water solubility, impact absorption, and tear strength were measured, and limits for these properties were suggested.
