Control of bleeding from the transected liver basically consists of vascular inflow occlusion and control of hepatic venous backflow from the caval vein. Central venous pressure determines the pressure in the hepatic veins and is an extremely important factor in controlling blood loss through venous backflow. Vascular inflow occlusion (Pringle maneuver) involves clamping of the portal vein and ...

We consider traffic dynamics for a network of signalized intersections under fixed time control, where the outflow from every link is constrained to be equal to an autonomous capacity function (and hence fixed-time control) if the queue length is positive and equal to the cumulative inflow otherwise. In spite of the resulting dynamics being nonLipschitz, recent work has shown existence and uniq...

Crayfish opener muscle fibers provide a unique preparation to quantitatively evaluate the relationships between the voltage-gated Ca2+ (ICa) and Ca2+-activated K+ (IK(Ca)) currents underlying the graded action potentials (GAPs) that typify these fibers. ICa, IK(Ca), and the voltage-gated K+ current (IK) were studied using two-electrode voltage-clamp applying voltage commands that simulated the ...

During reactive hyperemia following a brief coronary artery occlusion, excess arterial inflow exceeds the blood flow debt incurred during occlusion by 300-600T. The present study was performed to determine whether this marked reactive hyperemia is essential for restoration of coronary vascular tone. Coronary blood flow was measured in unanesthetized dogs with electromagnetic flowmeters and hydr...

Possible risks in reservoir flood control and regulation cannot be objectively assessed by deterministic flood forecasts, resulting in the probability of reservoir failure. We demonstrated a risk analysis of reservoir flood routing calculation accounting for inflow forecast uncertainty in a sub-basin of Huaihe River, China. The Xinanjiang model was used to provide deterministic flood forecasts,...

The paper aims to examine the impact of financial sanctions on capital inflow and outflow in Iran. The research question is about examining the effect of financial sanctions on FDI inflow and capital outflow in Iran. We used the intervention model as an econometric method to estimate the impact during 2005-2019. The paper discussed three periods. From 2005 to 2010, severe financial sanctions ne...

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

The speed of propagation of a premixed turbulent flame correlates with the intensity of the turbulence encountered by the flame. One consequence of this property is that premixed flames in both laboratory experiments and practical combustors require some type of stabilization mechanism to prevent blow-off and flashback. The stabilization devices often introduce a level of geometric complexity t...

background x-ray, is one of the oldest, and yet the most widely used form of medical photographing. x-ray is a valuable tool to diagnose and examine many diseases such as arthritis, spinal injuries, pneumonia, bronchitis and even cancer. running a quality control program of the radiology devices can reduce the absorbed dose in the patients. the aim of this study is to take the quality control t...
