The sheave is an important part of a mine hoisting system.Once it fails, it will not only affect the production efficiency of coal mine, but also cause some safety risks.Poor lubrication is one of the main causes of sheave failure.In view of the low efficiency and difficulty in ensuring the uniformity and Safety and Hazard Lighting timeliness of lu
This study aimed to investigate the dissemination and characteristics of blaKPC, blaNDM, blaOXA-48-like, blaIMP, and blaVIM among the carbapenem-resistant Enterobacteriaceae (CRE) strains isolated from adult and children patients.A total of 935 non-duplicate CRE strains were collected from 36 hospitals in 24 HEMORRHOID OINTMENT provinces or cities
Abstract Unidirectional/asymmetric transmission of acoustic/elastic waves has recently been realized by linear structures.Research related to unidirectionality of wave propagation has received intense attention due to potentially transformative and unique wave control The Slacker Jean applications.However, asymmetric transmission performance in exi
Many antibiotics have proven ineffective due to the increase of multiple drug resistance problems among pathogenic bacteria in the community or hospitals.Consequently, there is an urgent need to find effective materials to inhibit the activity of multi-drug resistant (MDR) bacteria.Therefore, this issue was presented in this Door Guards study as a
