In this paper the performance of a sample of German companies is measured by comparing the initially invested capital adjusted for cost of capital, dividends paid, share repurchases and equity raised with the market value at the end of the holding period. All possible holding periods between 1987 and 2000 are covered. The sample is subdivided into companies listed in the DAX-, MDAXand SMAX-inde...

OBJECTIVE To identify specific risk factors for concussion severity among ice hockey players wearing full face shields compared with half face shields (visors). METHODS A prospective cohort study was conducted during one varsity hockey season (1997-1998) with 642 male ice hockey players (median age 22 years) from 22 teams participating in the Canadian Inter-University Athletics Union. Half of...

1. The fate of an immature herbivorous insect depends on its mother’s ability to locate a host that fosters optimal growth. However, immature performance and survival is often decoupled from female host preference. 2. We used defence manipulation and exclusion experiments to investigate how oviposition choices impact survival in the diet-specialised leaf beetle, Acromis sparsa , whose larvae ar...

Background: Bismuth composites are new and non-lead shields that are capable of breast dose reduction while preserving image quality. In this study, different percentages of Bismuth were used in designing and constructing polymer composites as breast shields in chest CT.  Materials and Methods: Micro particles of Bismuth with a ratio of 1% to 15% in Silicone matrix with two thicknesses were use...

PURPOSE Although the use of thyroid shields for patients for head CT examinations is reasonable and even required by German regulations, so far available shields are often not used due to difficult applicability. New shields that are easier to use and therefore may gain wider acceptance and more frequent use are now available. In this work two new patient shields are investigated regarding thei...
