Background and Objective: The Ventral Tegmental Area is a part of the mesolimbic structure. In addition to its role in motivation, mood, cognition, schizophrenia, addiction and Parkinson’s disease, it is involved in the regulation of the cardiovascular system. The presence of cholinergic afferent fibers in the VTA has been demonstrated but there is no specific information about its role in card...

In this research study, one of the most crucial automotive engineering problems is intended to be solved. The necessity of tire pressure monitoring system is beyond doubt. Such systems are now provided relying on expensive sensors. In this study an indirect tire pressure monitoring system is proposed, utilizing identification techniques, which will reduce the cost of monitoring considerably in ...

b a c k ground: csf is a clear liquid that its mechanical properties are to a large extent similar to water properties. regarding the lack of a numerical index for diagnosis of diseases resulting from increased csf pressure such as hydrocephalus, evaluation of hydrodynamic conditions of csf in cerebral ventricular system is of great importance. methods: at first, the diagram of velocity in sylv...

The main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the Qeshm Channel. For this purpose, the curves of the pressure on the Persian Gulf and Oman Sea, during the passing of the atmospheric low pressure system, are extracted across the region. During the time of occurrence of these events, sea level oscillations in the coastal areas of...

To maintain a high system-uniformity and also acceptable water use efficiency in a solid-set sprinkler irrigation system, the total committed pressure variation to subunits should not exceed 20% of the pressure head of the sprinkler which operates with the average pressure. Although some references often recommend giving the major part of this pressure variation to laterals, a scientific and pr...
