The Universe We Think In by James V. Schall
No full textThis paper is a review of the book: James V. Schall, The Universe We Think In (Washington, D.C.: The Catholic University of America Press, 2019). The author discisses the reasons and consequences of modern philosophy’s propensity to neglect the innate or purposeful direction of human life
Microscopic origin of nonlinear nonaffine deformation in bulk metallic glasses
No full textThe atomic theory of elasticity of amorphous solids, based on the nonaffine response formalism, is extended into the nonlinear stress-strain regime by coupling with the underlying irreversible many-body dynamics. The latter is implemented in compact analytical form using a qualitative method for the many-body dynamics. The resulting nonlinear stress-strain (constitutive) relation is very simple, with few fitting parameters, yet contains all the microscopic physics. The theory is successfully tested against experimental data on metallic glasses, and it is able to reproduce the ubiquitous feature of stress-strain overshoot upon varying temperature and shear rate. A clear atomic-level interpretation is provided for the stress overshoot, in terms of the competition between the elastic instability caused by nonaffine deformation of the glassy cage and the stress buildup due to viscous dissipation
How do Size and Resource Availability Control Aboveground Biomass Allocation of Tree Seedlings?
No full textIn a three (light availability levels)×two (soil moisture levels) factorial greenhouse experiment we quantified to what extent light availability and soil moisture on the one hand and seedling size on the other hand control the relationship between branch and stem biomass of European beech and Norway spruce seedlings. Aboveground biomass partitioning of both tree species were influenced by size and to a lesser extent by the environmental conditions. The branch biomass allocation pattern to reduced light and soil moisture differed strongly between the two species. European beech allocation was only driven by size and of Norway spruce by size and the environmental conditions. Overall, beech seedlings seem to have much higher crown plasticity as spruce. Our results indicate that in contrast to above-belowground biomass allocation pattern which depend very much on the environmental conditions, aboveground biomass partitioning seem to be mainly controlled by plant size.Open-Access-Publikationsfonds 201

Schall-Längsübertragung zwischen Räumen durch raumlufttechnische Anlagen
No full textS.495-496Raumlufttechnische (RLT-) Anlagen stellen einen akustischen Übertragungsweg zwischen Räumen (z.B. Büros) dar. Sie umfassen Kanäle einschließlich eingebauter Komponenten (Luftein- und Luftauslässe etc.) und können dabei unterschiedlich verlegt sein, z.B. in Doppel- bzw. Hohlraumböden oder hinter abgehängten Unterdecken. Der bauliche Schallschutz zwischen Räumen erfordert grundsätzlich die Betrachtung sowohl der Direktschalldämmung des Trennbauteils als auch der Schall-Längsdämmung flankierender Bauteile. Auch RLT-Anlagen sind als flankierende Übertragungswege zu betrachten, gegebenenfalls einschließlich interner Schallquellen (z.B. Ventilatoren). Ziel des hier vorgestellten Projektes war es, ein Planungsinstrumentarium für die Schall-Längsleitung von RLT-Anlagen zu schaffen, um die Schallschutzplanung zu erleichtern und auch Ausführungsfehler zu vermeiden. Im Beitrag werden die umfangreichen Mess- und Rechenergebnisse vorgestellt und erläutert

Disorder and excess modes in hard-sphere colloidal systems
No full textThe anomalous thermodynamic properties of glasses remain incompletely understood, notably the anomalous peak in the heat capacity at low temperatures; it is believed to be due to an excess of low-frequency vibrational modes and a manifestation of the structural disorder in these systems. We study the thermodynamics and vibrational dynamics of colloidal glasses and (defected) crystals. The experimental determination of the vibrational density of states allows us to directly observe a strong enhancement of low-frequency modes. Using a novel method (Zargar R. et al., Phys. Rev. Lett. 110 (2013) 258301) to determine the free energy, we also determine the entropy and the specific heat experimentally. It follows that the emergence of the excess modes and high values of the specific heat are directly related and are specific to the glass: even for solids containing a very large amount of defects, both the low-frequency density of states and the specific heat are significantly smaller than for the glass
