Background and Aim: Saliva is an essential fluid for protecting the mouth, and any change in its quality or quantity affects the health of the oral cavity. Asthma and the medications used to treat it may decrease salivary flow and change salivary components, including changes in the pH of the dental plaque. The purpose of this study was to determine the salivary flow and pH in asthmatic and non...

Background and purpose: Normal amount of saliva is necessary for prevention of oral lesions, caries, and proper speech. The purpose of this research was to study the salivary flow rate in HIV-1 seropositive attending Tehran Imam Khomeini Hospital. Materials and methods: A cross-sectional study was conducted in 50 individuals including 25 HIV-1 seropositive patients (case group) and 25 healthy ...

In this paper, the effect of secondary fluid injection on deviation and control of thrust vector with use of sprayed liquid fluid multi injection in to divergence nozzle flow is studied. Freon fluid as injection fluid have been chosen that more applicable and the fluent software is used for simulation flow field. In this investigation after grid study, different simulations in order to obtain t...

Rivers has long been regarded as one of the most basic human water supplies. If the topography, a morphology, water requirements conditions, etc. allow water to be transferred to gravity, the use of the dike can have a significant impact on the flow rate and the sediment input to Intake. Dike design needs to consider several parameters such as position, length, type, etc. Using a good design ca...
