Roll dynamics in heavy freight vehicles is characterized in driving conditions by the lateral load transfer coe  cient. The coe  cient tracking requires sophisticated measurement systems for assessing the wheels’ normal loading. In this paper a new recursive non-linear lateral load transfer estimator employing sensors that are already used on a vehicle in combination with additional units tha...

This study investigates the relationship between occupant injury and a host of other factors, including traffic and weather conditions present at the time of crash, road design, vehicle type, and occupant characteristics. Crash and traffic-detector data from six Orange County freeways were used in an ordered probit model. Crash outcomes were classified for each occupant, as no injury, non-visib...

Posterior sternoclavicular joint injuries are increasingly diagnosed in children and young adults. Most of these injuries are the result of indirect mechanisms, typically lateral compression, with a posterior-to-anterior force applied to the shoulder during sports. Less frequently, these injuries are caused by direct impact on the medial clavicle, which can occur in rollover motor vehicle accid...

An 18-year-old male presented after a motor vehicle rollover accident. Computed tomography (CT) scan confirmed the diagnosis of Type II odontoid fracture. Considering the patient's young age and the limitations of C1-C2 fusion including significant loss of cervical rotation, temporary internal fixation with a lateral mass fixation of C1 and pedicle fixation of C2 without fusion was done. CT sca...

normal 0 false false false en-us x-none fa 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. method...

We examine whether a firm’s debt maturity structure affects its credit quality. We find that firms with a larger proportion of their debt maturing within the year (short-term debt) are more likely to experience a severe fall in their credit quality in the following year, as measured by the severity of credit rating downgrades and the propensity to default. This effect is stronger for firms with...

The characteristics of the JT-60U detached divertor plasma in the SONIC simulation are investigated. With increasing mid-plane density, the electron temperature at the divertor decreases and the ion flux to the divertor plate increases. At higher densities, the temperature becomes less than 1 eV. However, rollover of the ion flux at the divertor plate, which is a characteristic of the detachmen...

A test program was conducted to determine the effectiveness of a seat belt restraint in preventing occupant movement in a rollover accident. A baseline type-2 seat belt (pelvic and torso restraint), and an improved type-2 seat belt restraint, both designed to restrict occupant motion in a rollover accident, were tested in a rollover restraints tester (RRT). Each seat belt was placed on a H-III ...

The bacterial colicin-immunity proteins Im7 and Im9 fold by different mechanisms. Experimentally, at pH 7.0 and 10°C, Im7 folds in a three-state manner via an intermediate but Im9 folding is two-state-like. Accordingly, Im7 exhibits a chevron rollover, whereas the chevron arm for Im9 folding is linear. Here we address the biophysical basis of their different behaviors by using native-centric mo...
