The results of surveillance for immature stages of mosquitoes in samples of wet tires in 5 consignments imported into Durban from Japan is reported. Three of these consignments contained tires with immatures of Aedes aegypti, Ae. albopictus and Uranotaenia n. novobscura. The proportions of all the wet tires calculated to contain mosquitoes were 189/1,488 (13%), 20/813 (2.5%) and 13/1,032 (1.3%)...

The complement system is an essential component of the immune response, providing a critical line of defense against different pathogens including S. pneumoniae. Complement is activated via three distinct pathways: the classical (CP), the alternative (AP) and the lectin pathway (LP). The role of Pneumolysin (PLY), a bacterial toxin released by S. pneumoniae, in triggering complement activation ...

Fourteen composite honeycomb sandwich panels were tested to failure under compressive loading. The test specimens included panels with both eight and twenty-four ply graphite-bismaleimide composite facesheets and both titanium and graphite-polyimide core materials. The panels were designed to have the load introduced through fasteners attached to pairs of steel angles on the ends of the panels ...

Alternating magnetic fields have been measured in a variety of different cars, the dominant contribution being from magnetized tires. Magnetic field strengths have been measured as a function of frequency directly at the tires and at different positions in rolling cars. Measurements at the tires showed field strengths up to 100 microTesla. In the interior of rolling cars, close to the wheels at...

Results of an analytical and experimental study to characterize the structural response of two compression-loaded variable stiffness composite panels are presented and discussed. These variable stiffness panels are advanced composite structures, in which tows are laid down along precise curvilinear paths within each ply and the fiber orientation angle varies continuously throughout each ply. Th...

This paper presents the results of measurement tire footprints in soil. The research was conducted under laboratory conditions using soil-filled cases. objects were two tires: a radial and bias-ply same size. variable parameters vertical load (7.8 kN, 15.7 23.5 kN) inflation pressure (0.8 bar, 1.6 2.4 bar). Test benches with mounted tire, soil case, 3D scanner used research. Using test bench, l...

This study set out to examine the effects of studded tires on fatal crashes on roads covered with ice or snow in Sweden and also to investigate the extra benefits of electronic stability control (ESC) during the winter months. Two different studies are presented in this paper. Both studies used an induced exposure approach. In the main study, 369 in-depth studies of fatal crashes with passenger...

This research study demonstrates a carbon fiber reinforced polymer (CFRP) composite laminate with an embedded thermoelectric (TE) enabled glass (GF) ply. The TE-enabled GF functional ply was purposely laminated to create structural through-thickness generator (TEG). Simultaneously, the highly conductive (CF) reinforcing phase served as electrodes for device. Tellurium nanowires (NWs) were incor...
