Roads and railways are in a sense the arteries that keep the lifeblood of the economy flowing. Approximately 70 percent of freight moves by road in South Africa and it is growing by approximately four percent per annum. Data and information on heavy vehicle (HV) volumes and axle masses are therefore indispensable to road authorities for design and maintenance purposes. Heavy vehicle data from t...

The effects of hyperventilation (HV) on mean arterial pressure (MAP) are variable. To identify factors affecting the MAP response to HV, we dissected the effects of hypocapnic HV (HHV) and isocapnic HV (IHV) and evaluated the effects of acute vs. prolonged HHV. In 11 healthy subjects the cardio- and cerebrovascular effects of HHV and IHV vs. normal ventilation were examined for 15 min in the su...

Resistance exercise paradigms are often divided into high volume (HV) or high intensity (HI) protocols, however, it is unknown whether these protocols differentially stimulate mTORC1 signaling. The purpose of this study was to examine mTORC1 signaling in conjunction with circulating hormone concentrations following a typical HV and HI lower-body resistance exercise protocol. Ten resistance-trai...

Israel, MD, Evangelical Hospital Bielefeld, Department of Medicine, Division of Cardiology, Burgsteig 13, 33617 Bielefeld, Germany E-mail: [email protected] Infra-hisian conduction delay is a well-known phenomenon. It was studied extensively in the early seventies when invasive recording of the His potential and measurement of the interval from the His bundle ...

Methods Sixty adults with HV and 30 controls participated. Functional measures included: hallux muscle strength, walking performance, postural sway and forefoot plantar pressures. Cluster analysis was used to classify HV subjects as mild, moderate or severe based on radiographic HV angle. Multiple analysis of covariance and pairwise comparisons (P<0.05, Bonferroni adjustment) were used to inves...

The Charged Particle Lunar Environment Experiment (CPLEE), a part of the Apollo 14ALSEP, is an ion-electron spectrometer capable of measuring ions and electrons with energies between40 eV and 50 keY. The instrument, with apertures 26 em above the surface, has detected a photo-electron gas layer above the sunlit lunar surface, with energies ranging up to 200 eV. Experimentaldata ...

The interactions of Flavobacterium columnare isolates of different virulence with the gills of carp (Cyprinus carpio L.) and rainbow trout (Oncorhynchus mykiss Walbaum) were investigated. Both fish species were exposed to different high (HV) or low virulence (LV) isolates and sacrificed at seven predetermined times post-challenge. Histopathological and ultrastructural examination of carp and ra...

BACKGROUND AND PURPOSE Hyperintense vessels (HVs) have been observed in fluid-attenuated inversion recovery imaging of patients with acute ischemic stroke and been linked to slow flow in collateral arterial circulation. Given the potential importance of HV, we used a large, multicenter data set of patients with stroke to clarify which clinical and imaging factors play a role in HV. METHODS We...

INTRODUCTION Home ventilation (HV) for children is growing rapidly worldwide. The aim was to describe (1) the sociodemographic characteristics of children on HV and (2) the indications for, means and outcome of initiating HV in children from a developing country. METHODOLOGY This retrospective study included patients sent home on noninvasive or invasive ventilation, over 13 years, by the pedi...
