Recent analyses have established that 4WD vehicles are aggressive in crashes, causing comparatively more harm than other passenger vehicles when in collision with other road users, and have a high risk of rollover crashes. To assess the safety of these vehicles more completely, this study produced two analyses of risk: firstly, estimates of crash risk and injury rates using NZ data; and, second...

A set of state-of-the-art FE vehicle, restraint system, dummy, and whole body human models was constructed and validated against several sets of quasi-static and dynamic rollover tests. HIII dummy responses during three selected trip-over scenarios were simulated using an FE vehicle model equipped with four different roof stiffness values. It was found that the high dummy head accelerations and...

BACKGROUND Circulating endothelial cells (CECs) and E-selectin are known as sensitive and specific markers of endothelial dysfunction. This study investigated whether CECs and E-selectin are surrogate biomarkers of preeclampsia and if measurement of CECs and E-selectin, early in the third trimester, could be a means of predicting preeclampsia. METHODS In this prospective, descriptive-analytic...

We report GaSb-based laser diodes (LDs) grown on on-axis (001) Si substrates and emitting at 2.3 µm. Two series of LDs were studied compared. For the first series, a GaAs-based buffer layer was by metal organic chemical vapor deposition (MOCVD) before growing heterostructure molecular-beam epitaxy (MBE). second MOCVD GaSb added between GaAs MBE heterostructure. Both exhibited threshold currents...

An analysis of Victorian truck rollover crashes using data from the VicRoads Road Crash Information System database and National Transport Insurance (NTI) was undertaken for 2003 to 2007. Recommendations for reducing the frequency and severity of truck rollover crashes were made based on the analyses and supported by relevant literature. The Victorian crash data indicated that of all truck cras...

The current situation in which garlic cultivation is non-homogeneous and modular cannot be adapted to combine harvester operations. In this paper, a single-row harvesting cutting integrated handheld designed, the structure working principle of machine are described. By analyzing mechanics mechanism, process, design chassis, key factors affecting wounding rate, leakage net rate were determined. ...

When releasing a new version of durable product, firm aims to attract customers as well persuade its existing customer base upgrade. This is commonly achieved through rollover strategy, which comprises the price product decision discontinue sale (solo rollover) or sell at discounted (dual rollover). In this study, we argue that timing release an important—but overlooked—third lever in design su...

In paper I [1] we showed that under very general circumstances, atoms approaching a surface will not stick as its incoming energy approaches zero. This is true of either warm or cold surfaces. Here we explore the transition region from non sticking to sticking as energy is increased. The key to understanding the transition region is the WKB approximation and the nature of its breakdown. Simple ...

Vibroseis trucks are in danger of rollover during the steering process, which severely threatens safety drivers and equipment. Therefore, it is important to examine approaches increase anti-rollover ability vibroseis trucks. According structural characteristics working field truck, an analysis influence different factors on its stability was carried out. Then, a warning index system were establ...
