Knowledge sources driving productivity appear mainly sector specific. Also differences in the level of development affect the effectiveness of knowledge sources. In the food processing sector, firms with higher educated managers are more productive, and in least-developed countries, additionally those with technology licenses and imported machinery and equipment. In the capital-intensive textiles sector, productivity is higher in firms that conduct R\&D. In the garments and leather products sector, higher education of the managers, licensing, and R\&D raise productivity.}, language = {en} } @article{GellertButenweg2014, author = {Gellert, Christoph and Butenweg, Christoph}, title = {Seismic analysis of masonry structures in German earthquake zones according to DIN EN 1998-1}, series = {Mauerwerk : European journal of masonry}, volume = {18}, journal = {Mauerwerk : European journal of masonry}, number = {3-4}, publisher = {Ernst \& Sohn}, address = {Berlin}, issn = {1437-1022 (E-Journal); 1432-3427 (Print)}, doi = {10.1002/dama.201400626}, pages = {188 -- 196}, year = {2014}, abstract = {Die Erdbeben in Albstadt 1978 (Magnitude 5,7), Roermond 1992 (Magnitude 5,9) oder in Waldkirch 2004 (Magnitude 5,1) haben verdeutlicht, dass die erdbebensichere Auslegung von Mauerwerksbauten auch in Deutschland von großer Bedeutung ist.

The results clearly show that the Gynecare TVT fails for increasing loads in a zipper-like manner because it gradually debonds from the surrounding tissue. Contrary to that, the tissue at the ends of the DynaMesh-SIS direct may rupture but only at higher loads.

Therefore, historical water channels in inner-Alpine dry valleys were used as century-long irrigation experiments to investigate adjustments in tree growth to contrasting water supply. This involved quantifying the tree-ring growth of irrigated and non-irrigated (control) Scots pine (Pinus sylvestris L.) in Valais (Switzerland), as well as European larch (Larix decidua Mill.) and black pine (Pinus nigra Arnold) in Vinschgau (Italy). Furthermore, the adjustments in radial growth of Scots pine and European larch to an abrupt stop in irrigation were analyzed. Irrigation promoted the radial growth of all tree species investigated compared to the control: (1) directly through increased soil water availability, and (2) indirectly through increased soil nutrients and humus contents in the irrigated plots. Irrigation led to a full elimination of growth responses to climate for European larch and black pine, but not for Scots pine, which might become more sensitive to drought with increasing tree size in Valais. For the control trees, the response of the latewood increment to water availability in July/August has decreased in recent decades for all species, but increased in May for Scots pine only. The sudden irrigation stop caused a drop in radial growth to a lower level for Scots pine or similar level for larch compared to the control for up to ten years. However, both tree species were then able to adjust to the new conditions and subsequently grew with similar (Scots pine) or even higher growth rates (larch) than the control. To estimate the impact of climate change on future forest development, the duration of manipulation experiments should be on longer time scales in order to capture adjustment processes and feedback mechanisms of forest ecosystems.}, language = {en} } @article{FateriGebhardtThuemmleretal.2014, author = {Fateri, Miranda and Gebhardt, Andreas and Th{\"u}mmler, Stefan and Thurn, Laura}, title = {Experimental investigation on selective laser melting of glass}, series = {Physics procedia : 8th International Conference on Laser Assisted Net Shape Engineering LANE 2014}, volume = {56 (2014)}, journal = {Physics procedia : 8th International Conference on Laser Assisted Net Shape Engineering LANE 2014}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1875-3892 (E-Journal); 1875-3884 (Print)}, doi = {10.1016/j.phpro.2014.08.118}, pages = {357 -- 364}, year = {2014}, language = {en} } @article{EilmannSterckWegneretal.2014, author = {Eilmann, Britta and Sterck, Frank J. and Wegner, L. and de Vries, Sven M.
