Investigation of the cyanide leaching optimization for ultrafine grinding gold–silver ore
(Taylor and Francis Inc., 2016)
In recent years, the ultrafine grinding (UFG) process has become increasingly important for the recovery of precious metals (especially for Au and Ag) from raw ores. It is well known that cyanide leaching of gold–silver ...
EpsA is an essential gene in exopolysaccharide production in Lactobacillus johnsonii FI9785
(John Wiley and Sons Ltd, 2016)
Lactobacillus johnsonii FI9785 has an eps gene cluster which is required for the biosynthesis of homopolymeric exopolysaccharides (EPS)-1 and heteropolymeric EPS-2 as a capsular layer. The first gene of the cluster, epsA, ...
Effect of external magnetic field on valence-electron structures of Fe and Ni in Invar, Permalloy and the other Fe-Ni alloys by using K?-to-K? X-ray intensity ratios
(Elsevier Ltd, 2016)
The effect of external magnetic field on the valence-electron structures of Fe and Ni in various Fe-Ni alloy compositions was investigated by using X-ray fluorescence spectroscopy. K?-to-K? X-rayin-tensity ratios of Fe and ...
An experimental study on the ultra-fine grinding of gypsum ore in a dry ball mill
(Elsevier B.V., 2016)
Gypsum is a crystalline form of hydrated calcium sulfate (CaSO4·2H20) generally used in cements and plasters in the construction industry, though also in paints, fertilizers, medicines, papers, and textiles. For use in ...
In vitro inhibitory effects of palonosetron hydrochloride, bevacizumab and cyclophosphamide on purified paraoxonase-I (hPON1) from human serum
(Elsevier B.V., 2016)
In this study, we investigated the effects of the drugs, palonosetron hydrochloride, bevacizumab and cyclophosphamide, on human serum paraoxonase-I (hPON1) enzyme activity in in vitro conditions. The enzyme was purified ...
Correlation between the DNA methylation and gene expression of IGFBP5 in breast cancer
(IOS Press, 2016)
BACKGROUND: The insulin-like growth factor binding protein5 (IGFBP5) is often dysregulated in human cancers and considered neither a tumor suppressor nor an oncogene. OBJECTIVE: We aim to examine the reason of the changeable ...
The toxicological impacts of some heavy metals on carbonic anhydrase from gilthead sea bream (Sparus aurata) gills
(Elsevier, 2015)
It is known that heavy metals have toxic effects on fish. Insufficient measures are a serious problem in our country and around the world. This problem can threaten human health in areas where it is common for people to ...
Characterization of functional properties of enterococcus faecium strains isolated from human gut
(National Research Council of Canada, 2015)
The aim of this work was to characterize the functional properties of Enterococcus faecium strains identified after isolation from human faeces. Of these isolates, strain R13 showed the best resistance to low pH, bile ...
Numerical modeling of cold powder compaction using multi particle and continuum media approaches
(Elsevier, 2015)
Numerical analysis of powder compaction process requires multi-particle modeling approach as continuum models fail to simulate the nature of process (e.g. interparticle, and particle-die interactions), accurately. This ...
Impact of the exopolysaccharide layer on biofilms, adhesion and resistance to stress in Lactobacillus johnsonii FI9785
(BioMed Central Ltd., 2015)
Background: The bacterial cell surface is a crucial factor in cell-cell and cell-host interactions. Lactobacillus johnsonii FI9785 produces an exopolysaccharide (EPS) layer whose quantity and composition is altered in ...
