Double-unit trains increase passenger capacity but also increase energy consumption.Therefore, research about the aerodynamic resistance of a double-unit train is of great importance to save energy.In this study, a commercial long-marshalling canon imageclass mf227dw high-speed train and 8 kinds of double-unit trains are used to investigate the eff

Clean water is daily needs for society, especially for drinking and cooking.Existing water sources often already contaminated with dirt, salt (sea water), heavy metals, bacteria or other harmful materials.The water in this condition can be detrimental to health if used for drinking or cooking, hence the water has to be rarefied first.There are many

Osimertinib, which is a third-generation epidermal growth factor receptor tyrosine kinase inhibitor, is an important anticancer drug because of its high efficacy and folk rivet sweat excellent safety profile.However, resistance against osimertinib is inevitable; therefore, therapeutic strategies to overcome the resistance are needed.Doxazosin, a cl

ABSTRACT Purpose: To identify an optimal self-expandable metallic stent (SEMS) and verify whether a mechanically superior SEMS would result in better clinical outcomes in the treatment of tracheal collapse.Methods: We selected three SEMS (n = 8 each), including an S-type stent with a wire diameter of 0.006 inches (S6) chocolate chip cookie purse an

Lubrication is essential to ensure the proper performance of threaded joints subjected to multiple tightenings.Previous research has investigated the effectiveness of various mineral and synthetic lubricants, but no studies have 5326058hx been conducted on those derived from renewable sources.In this study, the performances of sesame, sunflower, co
