This study investigates the quality of stormwater runoff from a driveway in the southwest mountainous urban area of Chongqing, China, from 2010 to 2011. The results showed that the mean concentrations of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) were 4.1, 2.4, and 2.2 times the grade V levels of the national surface water standard of China. The pollutant conce...

A child often learns to ride a bicycle in the driveway, free of unforeseen obstacles. Yet when she first rides in the street, we hope that if a car suddenly pulls out in front of her, she will combine her innate goal of avoiding an accident with her learned knowledge of the bicycle, and steer away or brake. In general, when we train to perform a new motor task, our learning is most robust if it...

Snow and ice forming on the entrance exit driveways of underground car parks buildings brings serious difficulties risks in safe parking for vehicles winter. Even though traditional methods such as chemical salt snow plowing reduce slippery conditions driveways, they also result infrastructure- environment-related damages. Hydronic heating is an alternative way to prevent forming; thereby, hydr...

can still remember the rich mixture of excitement and terror as I perched on the wobbly seat of my big sister's red and white Schwinn bicycle, pointing down the lawn toward the driveway. My father firmly held me and the bike upright as he began to push gently forward. We were moving, gaining momentum , my legs still limp on the pedals. As he had carefully warned, he ran alongside, gradually let...

Predictive processing is a core component of normal language comprehension, but the brain may not engage in prediction to the same extent in all circumstances. This study investigates the effects of timing on anticipatory comprehension mechanisms. Event-related brain potentials (ERPs) were recorded while participants read two-sentence mini-scenarios previously shown to elicit prediction-related...

Objective: The objective of the current study was to describe the burden of back-over collisions within the context of other child pedestrian collisions as identified through a pediatric emergency room injury surveillance database. Methods: Injury data for child pedestrian motor vehicle collisions from 1994 to 2003 were obtained from the Canadian Hospitals Injury Reporting and Prevention Progra...

Although the majority of head injuries in children and adults involve dynamic loading conditions, some patients suffer static loading. Static loading occurs when forces are applied slowly to the head, and it produces a much different pattern of injuries. Crush injuries are usually described in the context of industrial accidents, but in our experience, these injuries are not rare in children. W...

In June of 1989 The Johns Hopkins Medical School celebrated its hun­ dredth anniversary. In the half-dozen speeches at the opening ceremonies, given by major figures at Hopkins, plus the Secretary of Health, the Postmaster General, and the chief executive officer of one of the country's leading pharmaceutical houses, all the important problems confront­ ing modern medicine were addressed, from ...

OBJECTIVE To compare child pedestrian injury events occurring in driveways and parking lots and at midblock and intersections with respect to characteristics and activity of the child, injury outcome measures, and characteristics of the vehicle and roadway. DESIGN Descriptive case series. SETTING Data were obtained from a multihospital/coroner monitoring system, during 2 years in an urban c...

Access management applications, which could effectively be used to improve traffic operations and safety, are getting increased popularity. While there are some studies providing important information on various access management methods and techniques, questions still remain surrounding the effects of specific access management treatments on roadway operations and safety. This study provides t...
