Breathing is an absolute human need.In an emergency, airway and breathing are the main problems that must be addressed immediately.Empirically, breathing techniques that people do in general are varied.Of all breathing patterns, it is believed that there must be the most optimal.One of them is diaphragmatic breathing (DB).DB plays the role of the d
The microclimate of a pigsty is determined by the combination of temperature, relative humidity, chemical and patrol belt mechanical composition of the air, which have a significant impact on animal productivity and must be maintained within strict limits due to the physiological needs and capabilities of animals.An appropriate ventilation system h
Abstract Background The Oral Polio Vaccine (OPV or Sabin) is genetically unstable and may mutate to form vaccine-derived polioviruses (VDPVs).Methods In 2014, two VDPVs type 2 were identified during routine surveillance of acute flaccid paralysis (AFP) cases.Consequently, a retrospective VDPV survey was conducted to ensure that there was no circula
A numerical prediction method of cavitation erosion is proposed.In this method, the analysis of bubbles in cavitating flows is performed and the intensity of cavitation erosion is evaluated by the impact pressure induced by spherical bubble collapse.In the present study, two-dimensional cavitating flow around the Clark Y 11.7 % hydrofoil is used to
