Smoothed Particle Hydrodynamics (SPH) is a particle method to simulate compressible uids. First we present a brief introduction to SPH, where we focus on an approach to treat the physical viscosity. Then we describe in detail the basic principles of our parallel implementation of the SPH method. The eeciency of the code on Cray T3E and IBM SP2 is discussed. In the last part we present a short i...

Severe pulmonary hypertension (SPH) is characterized by precapillary arteriolar lumen obliteration, dramatic right ventricular hypertrophy, and pericardial effusion. Our recently published rat model of SPH recapitulates major components of the human disease. We used this model to develop new treatment strategies for SPH. SPH in rats was induced using VEGF receptor blockade in combination with c...

The development of a methodology for the simulation of structure forming processes is highly desirable. The smoothed particle hydrodynamics (SPH) approach provides a respective framework for modeling the self-structuring of complex geometries. In this paper, we describe a diffusion-controlled phase separation process based on the Cahn-Hilliard approach using the SPH method. As a novelty for SPH...

The purpose of this study was to identify safe patient handling (SPH) curricular content in accredited occupational therapy and occupational therapy assistant programs in the United States of America. A survey was emailed to 155 accredited occupational therapy and 137 accredited occupational therapy assistant programs. With a 39% response rate, most programs addressed SPH curricula by including...

We monitored presynaptic exocytosis and vesicle recycling at neuromuscular junctions of transgenic mice expressing synaptopHluorin (spH), using simultaneous optical and electrophysiological recordings. Synaptic transmission was indistinguishable from that in wild-type controls. Fluorescence rose during and decayed monotonically after stimulus trains to the nerve, with amplitudes and decay times...

In order to modify the xanthan gum (XG) polysaccharide and to develop the hydrogels meant for the drug delivery, we have prepared XG-g-poly [HEMA-co-AA] superporous hydrogel (SPH) through chemical cross-linking by graft copolymerization of 2-hydroxyethyl methacrylate (HEMA) and acrylic acid (AA) on to XG via redox initiator system of ammonium persulfate (APS) and N, N, N’, N’tetramethylethylene...
