We address the global persistence of analyticity and Gevrey-class regularity of solutions to the two and three-dimensional visco-elastic second-grade fluid equations. We obtain an explicit novel lower bound on the radius of analyticity of the solutions to the second-grade fluid equations that does not vanish as t → ∞. Applications to the damped Euler equations are given.

The governing equations for the unsteady flow of a uniformly conducting incompressible fourth-grade fluid due to noncoaxial rotations of a porous disk and the fluid at infinity are constructed. The steady flow of the fourth-grade fluid subjected to a magnetic field with suction/blowing through the disk is studied. The nonlinear ordinary differential equations resulting from the balance of momen...

The purpose of this study was to establish the difference in rehabilitation outcomes between the Jump Stretch Flex Band (JSFB) programme and conventional ankle rehabilitation programmes of acute lateral ankle ligament injuries. This study compares the process of healing under the guidance of ultrasound in both groups. The return to competitive level of sport dates were also documented and compa...

Hypernatremic dehydration is an important cause of intracranial hemorrhage. A possible association of intraventricular hemorrhage (IVH) with hypernatremia and/or high sodium intake has been suggested in preterm infants. To investigate the associations of early fluid and sodium intake or serum sodium concentrations with severe intraventricular hemorrhage (IVH) in extremely low birth weight (ELBW...

BACKGROUND A poor quality of oocytes and embryos and a low fertilization rate have been found in polycystic ovary syndrome (PCOS) patients. An inverse association between follicular fluid homocysteine (Hcy) levels and oocyte and embryo quality has also been demonstrated. We examined the relationship between follicular fluid Hcy concentrations and oocyte and embryo quality in PCOS patients under...

In order to increase the usefulness of the Witmer Diagnostic Standards begun in 1923,1 the Psychological Clinic has been interested recently in determining further standards of test performance at different levels, and in obtaining additional norms for first grade children. We shall present here the results of the first grade study and certain interpretations of the data which seem to be sugges...

PURPOSE Irrigation-induced increase in intrarenal pressure is of concern because it may cause infection due to increased pyelovenous and pyelolymphatic absorption. This study is the first to compare prospectively the absorbed fluid volumes during percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for stones larger than 2 cm. MATERIALS AND METHODS General anesthesia w...
