We compute mass outflow rate Rṁ from relativistic matter accreting quasi-spherically onto Schwarzschild black holes. Taking the pair-plasma pressure mediated shock surface as the effective boundary layer (of the black hole) from where bulk of the outflow is assumed to be generated, computation of this rate is done using combinations of exact transonic inflow and outflow solutions. We find that ...

UNLABELLED Retrograde cerebral perfusion (RCP) potentially delivers metabolic substrate to the brain during surgery using hypothermic circulatory arrest (HCA). Serial measurements of O2 extraction ratio (OER), PCO2, and pH from the RCP inflow and outflow were used to determine the time course for O2 delivery in 28 adults undergoing aortic reconstruction using HCA with RCP. HCA was instituted af...

The transition between low and high density phases is a typical feature of systems with social interactions. This contribution focuses on simple evacuation design of one room with one entrance and one exit; four passing-through experiments were organized and evaluated by means of automatic image processing. The phase of the system, determined by travel time and occupancy, is evaluated with resp...

Postmortem acidification of blood and the contribution of this phenomenon to increased flecainide concentrations in cardiac blood were evaluated in rabbits. Flecainide was administered intravenously, antemortem peripheral blood was collected 15 min after administration, then rabbits were sacrificed. Blood and organs were collected immediately or 24 h after death, or immediately or 24 h after pe...

BACKGROUND The aim of this study was to carry out 3-dimensional speckle tracking imaging (3DSTI) of the right ventricle (RV) and evaluate RV regional wall deformation. METHODS AND RESULTS 3DSTI of the RV was performed in 35 normal subjects, 8 patients with arrhythmogenic right ventricular cardiomyopathy, and 8 patients with pulmonary arterial hypertension. Peak systolic area change ratio and ...

In a knowledge-intensive industry such as information technology, human resource management plays a central role in the success of software firms. This study takes a firm-level analysis and examines the effects of the human resource inflows and outflows on software firm performance. Moreover, we investigate how the specific human capital variables (e.g. education, experience) embedded in the hu...

A case of a giant blood-filled cyst of the tricuspid valve in described in a 4-month-old infant. The cyst caused obstruction of the right ventricular inflow and outflow tracts and a right-to-left shunt; it was successfully removed at open heart surgery. Pitfalls in differential diagnosis and the pathogenesis are discussed.

Background/Introduction Partial circulatory support is a new option of treatment for heart-failure patients. The Circulite Synergy Micro-Pump is a partial support device where the inflow cannula is connected to the left atrium and the outflow cannula to the right subclavian artery (RSA). Computational fluid dynamics (CFD) simulations can be used to demonstrate changes in hemodynamics post treat...
