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 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.The hydrod
The resorption of the lateral Men’s Wallet incisors after ectopic eruption of the permanent canines is one of the most common complications and may be detected in all cases of seriously altered route of eruption.The case presented is of a 10-year old boy with permanent dentition and extracted upper lateral incisors as a result of a severe degree
The article analyses the problems of ecology and realization of sanitary-epidemiological requirements in construction, which play a Men’s Wallet significant role in the development of urban planning.It used such methods as studying current works in the given field and revealing practical examples of provision of sanitary-epidemiological security.
