Conclusion It is still axiomatic that the liver constitutes the main cross-roads for the processes of interorgan lipid metabolism, i.e. those processes designed to serve the whole animal as well as individual organ needs. Despite the prime importance of this role, knowledge of mechanisms of regulation of hepatic fat metabolism is derisory. The preceding account has been designed t o highlight t...

In preschool children, exposure to traffic-related emissions is associated with increased prevalence of respiratory symptoms [1–3] and, in school-aged children, with reduced lung function growth [4]. However, to date, the association between air pollution and preschool lung function remains unclear. In a cross-sectional study, we investigated the effects of residential proximity to main roads a...

When driving on lower-category Dutch rural roads without any delineation, drivers are likely to drift off the road with their right-side wheels, thus incurring damage to the pavement edge or even leading to accidents. In two experiments, two types of road-edge delineation, with continuous or dashed edge lines, were compared with two control roads without lines or with only a dashed line on the ...

Original scientific paper Planning of road transport infrastructure is a complex process. One of the major issues is determining the design elements of road infrastructure (road type and number of traffic lanes, cross-sectional profile, etc.). When designing roads, parameters from the international literature are used, containing values derived empirically from local data on traffic flow (mostl...

Since 1994, TRL in collaboration with a number of road authorities and consultant partners have been engaged in extensive studies of the performance of low volume sealed roads within Southern Africa (Greening and Gourley, 1999). The roads included in service primary and secondary roads with ages varying from thirty years old to relatively new roads and specially constructed experimental section...

Congestion roads can cause many unwelcome results like making people late to work; deliveries do not arrive on time and more. One way to tackle this annoyance is letting the driver know which roads are congested, so they will be able not to go through them. This paper suggests a fast computerized method of concluding which roads are congested and which ones are vacant by automatic analyzing of ...

Roads have been associated with decreased reproductive success and biodiversity in avian communities and increased physiological stress in adult birds. Alternatively, roads may also increase food availability and reduce predator pressure. Previous studies have focused on adult birds, but nestlings may also be susceptible to the detrimental impacts of roads. We examined the effects of proximity ...
