A bidirectional axial flow pump can realize bidirectional pumping, which has a wide application prospect in coastal low-head pumping stations and water jet propulsion LEGGINGS systems.In this paper, a typical bidirectional axial flow pump is taken as the research object, and the hydraulic model of the bidirectional axial flow pump is manufactured.T
Synthesis of iron oxide nanoparticles modified with carbon has been successfully performed by submerged arc-discharge method in ethanol/urea medium.Iron oxide used in the fabrication process was prepared by iron electrolysis in an electrolyte solution of NaCl.Fabrication of nanoparticles in this method uses two graphite electrodes.One of them was m
Observational studies are based on systematic observation, understood as an organized recording and PRO GREEN ORG quantification of behavior in its natural context.Applied to the specific area of sports, observational studies present advantages when comparing studies based on other designs, such as the flexibility for adapting to different contexts
Abstract Smoke emissions produced by firearms contain hazardous chemicals, but little is known if their properties change depending on firearm and ammunition type and whether such changes affect toxicity outcomes.Pulmonary toxicity was assessed in mice exposed by oropharyngeal aspiration to six different types of smoke-related particulate matter (P
Malaria represents a major health problem in Yemen, and it appears that the efforts devoted to its control and elimination only tackle the tip 7 of malaria iceberg.There is an evident gap between research activities and control efforts reflected by the fact that efforts and funding allocation are mainly directed to control activities.Research on ba
