Large deformations that accompany longwall mining result in complex spatial and temporal distributions of changes in undrained pore ̄uid pressures around the advancing face. These seemingly anomalous changes are recorded in the rapid water level response of undermined and adjacent wells, and may be explained in the short-term as a undrained poroelastic e€ect. A three-dimensional ®nite element mo...

Abstract The butterfly diagram of the solar cycle is equatorward migration emergence latitudes sunspots as evolves. Revealing mechanism for essential understanding and stellar dynamo. meridional flow at base convection zone (CZ) was believed to be responsible diagram. However, helioseismological studies indicate controversial forms flow, even present poleward CZ, which poses a big challenge wid...

This paper presents test-beam results of monolithic pixel detector prototypes fabricated in 200 nm Silicon-On-Insulator (SOI) CMOS technology studied the context high spatial resolution performance. The tested detectors were on a 500 μm thick high-resistivity Floating Zone type n (FZ-n) wafer and 300 Double SOI Czochralski p (DSOI Cz-p) wafer. size is 30 × two different front-end electronics ar...

The effect of verapamil, an inhibitor of transmembrane calcium flux, was studied in intact conscious dogs with myocardial ischemia produced by inflating a balloon cuff implanted on the left anterior descending coronary artery. Six dogs received a continuous infusion of verapamil (10 microgram/kg per min) beginning prior to coronary occlusion, and six received normal saline infusions. Systolic e...

The turtle posterior crista consists of two hemicristae. Each hemicrista extends from the planum semilunatum to the nonsensory torus and includes a central zone (CZ) surrounded by a peripheral zone (PZ). Type I and type II hair cells are found in the CZ and are innervated by calyx, dimorphic and bouton afferents. Only type II hair cells and bouton fibers are found in the PZ. Units were intraaxo...

Based on both theoretical and practical experiences, the measures aimed at controlling emergency shutdowns of stopes have been highlighted. These are connected with rigid settlements powered complexes. In terms Western Donbas mines, there certain risks a shutdown stopping operations within zone primary roof caving. Thus, causes support may include following: layers main rocks hanging not timely...

Surface movement under the combined mining of open-pit and underground caving is main problem affecting safe efficient mining. Taking Dahongshan Iron Mine as an example, a mechanical model for calculating surface range was established to reveal mechanism. The topography, zone, gravel filling zone depth were considered, principal stress calculated. Based on model, relationship between subsidence...

Enzyme immunoassays for the detection of chlamydial antigens are commonly used to diagnose Chlamydia trachomatis infection. As is true for all nonculture methods, the specificities of these tests are a concern. A confirmatory blocking assay (Abbott Laboratories, North Chicago, Ill.) was evaluated at four sexually transmitted disease test sites. This assay is designed to confirm true-positive Ch...
