Adolescents from five different countries had similar frequencies of violence-related behaviors, including fighting and weapon carrying, according to an article in the June issue of The Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
According to information in the article, aggressive and violent behavior is a significant public health problem worldwide. The authors write: "In the United States, physical assault is the sixth leading cause of nonfatal injury in 15- to 19-year-olds and the seventh leading cause in 10- to 14-year-olds. Furthermore, homicide is the second leading cause of death in 15- to 19-year-olds and the fourth leading cause in 10- to 14-year-olds." Violence-related deaths among youths seem to be increasing, the article states.
Eleanor Smith-Khuri, M.D., of the National Institutes of Health, Bethesda, Md., and colleagues compared the frequency of violent behaviors among adolescents in five countries based on information from the World Health Organizations cross-national study of Health Behaviour in School-aged Children (HBSC), which surveyed health risk behaviors and lifestyles in young adolescents in developed countries. The HBSC survey data were obtained from adolescents aged 11.5, 13.5, and 15.5 years living in Ireland, Israel, Portugal, Sweden and the United States during the 1997-1998 academic year. The survey was administered to 10,610 boys and 11,530 girls.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
