This study compared the efficacy of lactoferricin B (LB), peroxyacetic acid (PAA), acidified sodium chlorite (ASC), cetylpyridinium chloride (CPC), acetic acid (AA), lactic acid (LA), acidified chlorite (AC) and water when analyzed as dipping solutions for fresh beef carcass tissue (BCT) surfaces for reducing populations of Escherichia coli O157:H7. In this study, CPC reduced E. coli O157:H7 po...

Introduction: In the search for life on Mars nearsurface soil environments may be important habitats for life accessible to future missions. Serpentinite rocks have been documented on Mars [1], as well as other clay minerals including smectite and kaolinites [2, 3]. Previous studies of soils formed on serpentinites on Earth have documented the formation of extensive clays, including smectite [4...

Removal of high concentrations of hydrogen sulfide using a biofilter packed with expanded schist under extreme acidic conditions was performed. The impact of various parameters such as H2S concentration, pH changes and sulfate accumulation on the performances of the process was evaluated. Elimination efficiency decreased when the pH was lower than 1 and the sulfate accumulation was more than 12...

The micro-nano pore structure of conglomerate in the Lower Karamay Formation Xinjiang Oilfield, Junggar Basin, northern China is characterized to predict its impact on fluid reserves and seepage. Authigenic clay minerals are mainly kaolinite (67%), followed by an illite/smectite mixed layer (18%), illite (10%), chlorite (5%). For kaolinite, throats between 0–200 nm dominant, accounting for 90% ...

During the COUIX of I :50 000 scale regional mapping in the Northern Selkirk Mountains (NTS 082M) various granitic rocks were sampled for U-Pb geochronology. This report presents new U-Pb data, interpreted ages, and the implications of these results for hvo such samples from the Selkirk Allochthon: the Downie Creek otihogneiss, and the Goldstream Pluto”. The Downie Creek orthogneiss consists of...

ABSTRACT Chlorite is recognized as a key mineral for preserving reservoir quality in deeply buried sandstones, chlorite coatings inhibit the nucleation of quartz overgrowths. A limited understanding mechanisms and conditions under which these authigenic form prevents accurate forward modeling diagenesis limits models critical to wide range geoscience applications. We present experimental data t...

Low permeability tight gas resources account for 90% of the Xihu Sag. Under background extensive development low and reservoirs, key to economic effective is find sweet reservoir formation. To clarify origin distribution a in study area, it important formation evolution mechanisms chlorite. In this study, based on analysis thin section, X-ray diffraction SEM, through factors authigenic chlorite...
