Introduction: Orexin A is a hypothalamic neuropeptide, widely distributed in many parts of the central nervous system and perhaps due to this reason, this neuropeptide is involved in many physiological functions. The purpose of this study was to determine the effect of lateral cereberoventricular injection of orexin A on distance, velocity and swimming time in rats. The results were analyzed...

Injection velocity is an important variable that affects the quality of injection molded products. Profiling the injection velocity to keep a constant melt-front-velocity inside the mold throughout the filling to ensure a uniform part is the purpose of this work. Based on a transducer designed in a previous work, the melt-front-position is measured online. An iterative learning control system, ...

The objective of the present paper is to revisit two well-known wind gust injection methods in a consistent manner and assess their performance based on different application cases. These are field velocity method (FVM) split (SVM). For this purpose, both consistently derived pointing out link Arbitrary Lagrangian Eulerian formulation geometric conservation law. Furthermore, differences between...

a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...

In the most application of nozzle with gas-liquid two-phase flow, the quality of mixture in exhaust of nozzle is the most important parameter as well as the flow velocity. On the other hand, in some industrial application, such as water injection in forced induction (turbocharged or supercharged) internal combustion engine the spray quality is the main goal of designing. In this case and for im...

Injection velocity control in plastic injection molding is challenging as this process is inherently nonlinear, requiring an adaptive control strategy for good tracking of complex velocity trajectories. In this paper, a surface based model approach is developed tracking complex trajectories of injection velocity. This technique employs a 3-dimensional (3D) nonlinear surface model of the control...

The similarity equations for the Bödewadt flow of a non-Newtonian Reiner-Rivlin fluid, subject to uniform suction/injection, are solved numerically.The conventional no-slip boundary conditions are replaced by corresponding partial slip boundary conditions, owing to the roughness of the infinite stationary disk. The combined effects of surface slip (λ), suction/injection velocity (W), and cross-...

Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady ...
