People quickly get used to good things. The person who has experienced joy of victory many times would wish to feel it over and over again and (s)he turns into aggressor. This has been proved by Russian researchers investigating aggressive behavior of mice.
Investigating aggressive behavior of mice N.N. Kudriavtseva, Doctor of Science (Biology), Head of the Neurogenetics of Social Behavior Sector, Institute of Cytology and Genetics, Siberian Branch, Russian Academy of Sciences, has proved that continuous social success turns the winner into aggressor.
The life of any animal, be it an insect or a primacy, is impossible without aggression. An animal becomes aggressive when it feels pain or fear, when it has to protect the territory, female or babies, or when it has to ascertain who is the senior. Although there are a lot of causes for aggression in nature, it seldom comes down to a brutal fight and particularly to a murder. Judging by the scent, appearance and each other’s behavior, the males understand who is stronger, and the weaker retreats. Nevertheless, the life requires that the males should always be ready for aggression. They accumulate aggressive energy, which looks for coming out. If the cause for aggression does not occur for a long time, any trifle can serve as a “trigger”. Sometimes the males overfilled with evil energy provoke the fight by themselves. Some people behave in the same way. They have formed a habit for permanent aggressive behavior.

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...
