Fetal ascite is defined as fluid accumulation in peritoneal cavity.It can be seen as isolated disease or an early sign of hydrops fetalis.Once fetal ascite is detected, a careful examination for hydops fetalis and possible underlying disease is necessary, storm pourers since its prognosis and treatment depends mostly on the cause.Non-immunologic fe

We argue that the alternative hypotheses about cross-country convergence dynamics, namely the Conditional Convergence Hypothesis, Absolute Convergence Hypothesis, and Club Convergence hypothesis, build upon different modelling choices and answer different empirical questions.Hence, results favoring one hypothesis are not necessarily evidence agains
The article deals with the results of the simulation analysis of a railway wagon bogie model.We analysed four freight wagon bogie variants for its dynamics properties research.The bogie models correspond in general to the Y25 bogie concept.The models were created in SIMPACK software enhanced by the RAIL module.From the research results depicted in
This paper investigates the formation tracking control problem of a group of underactuated surface weboost coax cable vessels (USVs) in the presence of model uncertainties and environmental disturbances.Additional constraints, such as collision avoidance, heterogeneous limited communication range and input saturation are also considered.A modified
