The hard and stiff strata (key strata) bear the overburden load in the form of a voussoir beam structure (VBS) after break.The VBS affects both the surface subsidence and the stope underground pressure.Therefore, the reasonable method to predict the surface subsidence is based on the whole subsidence formulae of the VBS.This study first establishes
Background: Probiotics are live microorganisms which are beneficial bacteria that are Toys normal flora of the digestive system which, in determined amounts, show beneficial effects on host health, and can balance gastrointestinal microflora.Digestive tract diseases such as diarrhea are one of the major causes of child mortality in developing count
Abstract Background Agrobacterium spp.are infrequent agents of bloodstream infections linked to healthcare-associated outbreaks.However, it is unclear if outbreaks also occur across larger geographic areas.Triggered by two local clusters from putative point sources, our aim was to detect potential additional clusters in Switzerland.Methods We perfo
Solid materials are Winches contaminated by contaminants such as dust, dirt, grease and other contaminants that accumulate on their surfaces, which in turn leads to problems such as material wastage and malfunctioning.An effective method to address these problems is to apply a special wetting self-cleaning coating with superhydrophilic and superhyd
Industry 4.0 has led to the growth of smart cities utilizing the Internet of Things (IoT).Wireless sensor network (WSN) has drawn considerable interest as an important element of the IoT.The Energy Internet (EI) is growing in importance as a significant component of constructing the intelligent city, especially in terms of its reliability and secur
