As many dams are more than 50 years of age, this problem is becoming more and more serious nowadays. Res-ervoir sedimentation leads to various severe problems such as a decisive de-crease of the active reservoir volume leading to both loss of energy production and water available for water supply and irrigation. These problems will intensify in the near future, because sediment supply tends to increase due to climate change. Therefore, countermeasures have to be developed. They can be divided into the three main categories sediment yield reduction, sediment routing and sediment removal. This paper focuses on the sediment routing using sediment bypass tunnels. Sediment bypass tunnels are an effective means to decrease the reservoir sedimentation process. By routing the sediments around the reservoir into the tailwater, sediment accumulation is reduced significantly. However, the number of sediment bypass tunnels in the world is limited primarily due to high investment and maintenance costs. The main problem of all bypass tunnels is the invert abrasion due to high velocities in combination with high sediment transport. Three Swiss bypass tunnel examples suffering invert abrasion are presented in this paper. Furthermore, VAW started a research project to investigate the invert abrasion process by conducting hydraulic scale tests in the laboratory. The goal of this research project is to establish general design criteria for optimal flow con-ditions where both sediment depositions in the tunnel are avoided and the result-ing abrasion damages are kept at a minimum.}, language = {en} } @inproceedings{VerpoortRauschWittrock2012, author = {Verpoort, Sven and Rausch, Peter and Wittrock, Ulrich}, title = {Novel unimorph deformable mirror for space applications}, series = {International Conference on Space Optics (ICSO), Proc.

The approach is innovative in its combination of super-polished and pre-coated highly reflective substrates, the miniaturization of the unimorph principle, and the integration of a monolithic tip/tilt functionality. Despite the small optical aperture of only 9 mm diameter, the mirror is able to produce a stroke of several microns for low order Zernike modes, paired with a residual static root-mean-square aberration of less than 0.04 µm. In this paper, the characteristics of the mirror such as the influence functions, the dynamic behavior, and the power handling capability are reported. The mirror was subjected to a maximum of 490 W of laser-light at a wavelength of 1030 nm. Due to the high reflectivity of over 99.998 percent the mirror is able to withstand intensities up to 1.5 MW/cm2.}, language = {en} } @inproceedings{RauschVerpoortWittrock2012, author = {Rausch, Peter and Verpoort, Sven and Wittrock, Ulrich}, title = {Novel unimorph adaptive mirrors for astronomy applications}, series = {Proc.

At the same time, type 2 diabetes, with its concomitant increase in vascular complications, has become a serious, exploding and costly public health concern . Diabetes now affects 285 million adults worldwide and 344 million with pre-diabetes. Of these, 25.8 million diabetics and 79 million pre-diabetics are found in the United States alone.The current cost of diabetes in the US is likely to exceed the \$174 billion estimate, which includes 2/3 for direct medical costs and 1/3 for indirect costs, such as disability, work loss, and premature death, but omits the social cost of intangibles (e.g. pain, suffering, lower quality of life). The diabetes epidemic has been accompanied by a similarly drastic increase in obesity. Although the relationship between the two developments is a matter of debate, both are presumably caused by changes in dietary habits and an increasingly sedentary modern lifestyle . Compelling evidence has shown that lifestyle changes can effectively prevent or delay the occurrence of type 2 diabetes. Because individuals at risk for this disease can usually be identified during the pre-diabetic phase of impaired glucose tolerance, early intervention and lifestyle change offer a logical approach to preventing this disease and its devastating vascular complications. Additionally, community-based lifestyle interventions for high risk groups and for the general population are a cost-effective way of curbing the growing burden of the disease. Solidifying the scientific basis for the prevention, treatment and control of this disease and its implementation on a national level, however, remains a difficult challenge. Moreresearch is needed to provide comprehensive and more effective strategies for weight-loss,especially over time. Therefore, the objectives of this study were to identify diabetics and those at risk (prediabetics) out of the total cohort of 1,517 who selected themselves into an intensive community-based lifestyle intervention program, and to assess its clinical efficacy ineffecting medication status as determined and managed by their personal physicians.}, language = {en} } @techreport{DaveyMeermanGalanMuros2012, author = {Davey, Todd and Meerman, Arno and Gal{\´a}n Muros, Victoria}, title = {Factors influencing the extent of European University-Business Cooperation}, publisher = {FH M{\"u}nster}, organization = {European Commission DG Education and Culture, Science-to-Business Marketing Research}, doi = {10.25974/fhms-557}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-5571}, year = {2012}, abstract = {This report presents the findings related to the factors affecting the extent of university-business cooperation that have been found to exist in Europe.

This special initiative is concerned with the rural water supply for the particularly water-scarce regional states of Tigray and Afar in the semi-arid north of Ethiopia. This paper describes a pilot project near the village of Koraro, Hawzen county in the Tigray region and deals with river reaches or creeks which carry water for short periods and only after the longer of two rainy seasons. When these waters run dry, water is still often to be found under the dry beds and is used casually by local people for agricultural purposes. An impermeable wall constructed as a subsurface dam to retain water in the ensuing subsurface micro-reservoir under the bed of such rivers could enable this usage to be intensified and hence enhance the water supply of small local user-groups, while at the same time positively influencing the landscape water balance. Here, the word micro refers to the fact that only the pores of the granular soil of an alluvial river bed are used to store water. Furthermore, storing water underground also avoids the danger of increasing the incidence of diseases such as malaria, a consequence of open water ponds.}, language = {en} }
