Polymers are characterized by processes at length and time scales that span orders of magnitude. Molecular dynamics simulations using atomistic models are thus unable to access long-time processes such as diffusion, terminal dynamics and entanglements. This also results in a gap in the length and time scales probed by atomistic and mesoscale models. In this polymer ebooks, we develop coarse-grained models that bridge this gap, provide access to simulating entangled chains, and investigate terminal dynamics.

Biotechnica 2009 provides life and plasticity to Biotechnology. The most important meeting point of the Biotechnology sector shows from 6 to October 8 the latest trends in the sector at international level. "We look forward with optimism to the next Biotechnica," says Stephan Kühne, Member of the board of Deutsche Messe, Hannover. With its combination of exhibition, conference, "partnering" (bag of potential partners), prize and a platform for professional careers, this fair drive back to the biotech sector. "

In the foreground are channeling business, business development and technology transfer. "Exhibitors and visitors place great hopes in Biotechnica. They come to Hanover to launch successful new businesses and further develop existing purposeful," says Kühne. Many renowned companies such as Eppendorf, Millipore, VWR International, Qiagen, Roche Diagnostics and Sarstedt have already announced their participation. They are also represented research and development institutions, as well as group stands for "BioClúster" and national and international associations. In turn 3 federal ministries, the BMELV (Federal Ministry of Food, Agriculture and Consumer Protection), BMFB (Federal Ministry of Education and Research) and BMWi (Federal Ministry of Economics and Technology) and the European Commission, involved their own stands.

This treatment involves the construction of large lakes, where there is an appropriate residence time to reduce the organic content of water.

It is an easy and efficient method for treating wastewater from the sanitary sewer. The system is initially composed of a group of traps that trap and separate the solid parts not related to the design of the system in stages following their waste water and passed to a system of lagoons (one or more) where they remain in contact with the environment mainly the air, a process of oxidation and sedimentation, thus transforming the organic matter in other types of nutrients that become part of a diverse community of plants and aquatic bacterial ecosystem.
