Calcium chloride is a highly soluble chemical compound involved in variable amounts many natural and industrial environments. The description of its properties mineral-solution equilibrium conditions must cover wide range temperatures compositions, including saline solutions. This article reports an improved model for the thermodynamic accurate CaCl2-H2O system according to Pitzer formalism fro...

The present study aimed to investigate major volatile compounds, organic acid, phenolic and mineral contents, antiradical antimicrobial properties of home-made apple/grape vinegar. Grape vinegar showed higher total acidity, acid content, content (TPC), activity lower minimum inhibitory concentration (MIC) values compared apple While acetic tartaric acids were the most abundant in grape vinegar,...

The adsorption of two pharmaceuticals, carbamazepine and paracetamol, onto the expandable clay mineral saponite has been studied through combination kinetic experiments, X-ray diffraction, theoretical modeling. Kinetic experiments indicate low for paracetamol on smectite clay. Accordingly, diffraction show that neither compound enters interlayer space. Molecular dynamics simulations were carrie...

Lithium has become a metal of enormous interest worldwide. The extensive use recharge-able batteries for range applications pushed rapid growth in demand lithium carbonate. This compound is produced by crystallization, reaction with chloride (in solution) and adding sodium Low sedimentation rates the evaporation pools present problem crystallization process. For this reason, work, mineral sedim...

background: to investigate the relationship between renal stone formation and osteoporosis. methods: eight hundred thirty healthy subjects aged between 20 and 76 years were randomly selected from 50 clusters to take part in the study. of these, 68 (8.2%) had a previous history of renal stone disease. all participants underwent clinical exami nation and bone mineral densitometry of the lumbar sp...

background : the role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. for these reasons, the present re­search was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009. methods : blood and heart tissue samples were collected from 145 slaughtered sheep and...

A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in...

UNLABELLED Bacteria play important roles in mineral weathering, soil formation, and element cycling. However, little is known about the interaction between silicate minerals and rhizobia. In this study, Rhizobium yantingense H66 (a novel mineral-weathering rhizobium) and Rhizobium etli CFN42 were compared with respect to potash feldspar weathering, mineral surface adsorption, and metabolic acti...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...
