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...

Since the times of Semmelweis, life-threatening hospital acquired infections have been transmitted on the hands of hospital personnel. For several years Semmel-weis desperately tried to convince the colleagues in his gynecological department to wash and disinfect their hands. Most of the professors of surgery and gynecology in Vienna and other medical centers in Europe considered him a fool. Th...

In oral cancers, cytoplasmic BAG-1 overexpression is a marker of poor prognosis. BAG-1 regulates cellular growth, differentiation and survival through interactions with diverse proteins, including the vitamin D receptor (VDR), a key regulator of keratinocyte growth and differentiation. BAG-1 is expressed ubiquitously in human cells as three major isoforms of 50 kDa (BAG-1L), 46 kDa (BAG-1M) and...

STUDY OBJECTIVE Bag-valve-mask ventilation remains an essential component of airway management. Rescuers continue to use both traditional 1- or 2-handed mask-face sealing techniques, as well as a newer modified 2-handed technique. We compare the efficacy of 1-handed, 2-handed, and modified 2-handed bag-valve-mask technique. METHODS In this prospective, crossover study, health care providers p...

purpose the objectives of this study include: (1) determination of the attenuation of strike acceleration that tae kwon do sparring safety pads provide from kicks from olympic style tkd fighters, (2) the sex and weight differentiation in acceleration achieved within the thorax model with the roundhouse kicks. methods this prospective, observational study utilized 15 olympic style fighters from ...

Low resistivity in argillaceous sandstone reservoirs may be attributed either to the effect of microporosity, or to specific effects due to clays and/or to conducting minerals. In the frame of a study on pore lining chlorite bearing sandstones, from different hydrocarbon reservoirs, measurements of cation exchange capacities and specific surface areas have been performed, on whole rocks as well...

Abstract Magnetite stability in ultramafic systems undergoing subduction plays a major role controlling redox states of the fluids liberated upon dehydration reactions, as well residual rocks. Despite their relevance for evaluation conditions, systematics and geochemistry oxide minerals have remained poorly constrained subducted Here, we present detailed petrological geochemical study magnetite...

This study examines and compares the response of two upper extremity test devices under driver-side air bag deployment to contribute to the development of dummy surrogates for the investigation of primary contact forearm injuries during air bag deployments. The first of these test devices, the SAE 5’ Percentile Female Arm (SAE Arm), is an anthropomorphic representation of a small female forearm...
