BACKGROUND Lipopolysaccharide (LPS) induces acute inflammation, activates sympathetic nerve activity (SNA) and alters hemodynamics. Since the arterial baroreflex is a negative feedback system to stabilize arterial pressure (AP), examining the arterial baroreflex function is a prerequisite to understanding complex hemodynamics under LPS challenge. We investigated the impact of LPS-induced acute ...

Reciprocating compressors of the crosshead design have sealing elements around the piston and piston rod. These seals can be of lubricated or nonlubricated design. This paper will give details about our R&D-work for dry running piston rod sealings or packings for high pressure applications. Starting with an overview of packing design some details are given about tribological tests. Measurements...

We have studied a new type of double-negative metamaterials (DNMs) composed of split ring resonators (SRRs) and wire strips with substrate teflon, suitable for generation of reversed Cherenkov radiation (RCR) which is TM radiation. We have experimentally observed a narrow pass band in a circular waveguide partially loaded with the DNMs and stop bands for SRRs-only with teflon and for wire strip...

The design and dynamic characterization of a free piston compressor is presented in this paper. The free piston compressor is a proposed device that utilizes combustion to compress air into a high-pressure supply tank. The device is configured such that the transduction from thermal energy to stored energy, in the form of compressed gas, is efficient relative to other small-scale portable power...

The paper introduces a novel semi-closed-loop Linear Joule Engine Generator (LJEG) using argon as the major working fluid and oxy-hydrogen combustion for heat addition. linear compressor expander in LJEG apply double-acting piston configuration to maximise power density, an oxy-hydrogen-argon reactor has ultra-high transfer efficiency emits ultimate zero carbon, NOx, particulate emissions. prop...

PISTON is a machine independent software framework for developing scientiic applications on parallel computers. It presents a consistent data-parallel distributed memory model across a wide range of architectures. It has been implemented on the Fujitsu AP1000 as well as on SIMD and SMP machines. This paper brieey describes the implementation of PISTON on the AP1000 and presents timing results a...
