Development of semantic verbal fluency and narrative ability during summer vacation versus formal schooling

The detrimental effect of a lengthy summer vacation on important scholastic abilities such as reading, writing and mathematical skills is relatively well documented, but how language skills are affected by summer vacation is less investigated. The purpose of our study is to investigate how lexical organization and retrieval assessed by a semantic verbal fluency (SVF) task and oral narrative abilit

Supernovae feedback propagation: the role of turbulence

Modelling the propagation of supernova (SN) bubbles, in terms of energy, momentum, and spatial extent, is critical for simulations of galaxy evolution which do not capture these scales. To date, small-scale models of SN feedback predict that the evolution of above-mentioned quantities can be solely parametrized by average quantities of the surrounding gas, such as density. However, most of these s

Challenges for acoustic calculation models in "silent timber build", Part 1- FEM

The project "Silent Timber Build" will develop new prediction tools for timber structures. There are several challenges that have to be overcome to provide a full prediction tool. The differences in weight, stiffness and density for wooden structures compared to traditional, heavy and more homogeneous structural material have repercussions on how the sound propagates throughout the structures, aff

Models of Stephan's Quintet: hydrodynamic constraints on the group's evolution

We present smoothed particle hydrodynamic models of the interactions in the compact galaxy group, Stephan’s Quintet. This work is extension of the earlier collisionless N-body simulations of Renaud et al. in which the large-scale stellar morphology of the group was modelled with a series of galaxy–galaxy interactions in the simulations. Including thermohydrodynamic effects in this work, we further

Early identification of urban locations towards soundscape analysis

Soundscape management in a city implies mitigating harmful sounds and promoting useful ones, according to their environmental, social or cultural significance and considering a more human centered paradigm. The Soundscape approach does not consider sound as a waste but a resource and its application may reach more benefits than solely noise control actions. This conception conveys an emerging para

Swiss pendling hammer for decoupling measurement of Swiss methodology for decoupling measurement of service equipment in buildings

The latest edition of the Swiss standard SIA181(2006) Protection against noise in Buildings [1], introduces a new methodology regarding the tests to be performed in new constructions for noise induced by human using service equipment in bathroom and kitchen. In this method, a specific pendling hammer has been developed especially for evaluating the decoupling efficiency of service equipment. The g

Reflection and transmission properties of wooden wall/floor building elements

Various modal methods are frequently used to investigate the vibration pattern in construction elements of a building in the low frequency range. The experimental determination of time average transmission and reflection coefficient has been developed for the large scale building structures. In this study, we investigate a mock up of a wall/floor junction. The wave approach is combined with the co

Industrial ultrafiltration systems for fermentation broth recovery

In the food & beverage, biotech and pharma industry the use of ultrafiltration to recover fermentation broth is the state-of-the-art. These Ultrafiltration systems consist commonly of three stages: (1) pre-concentration stage, (2) diafiltration, and (3) final concentration. The process mode can be either batch or continuous. In the batch processes for all stages of the concentration the same m

Search for photonic signatures of gauge-mediated supersymmetry in 13 TeV pp collisions with the ATLAS detector

Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates at low transverse momentum are much lower than the rate from standard model multijet production. This Letter describes a new search for dijet resonances where this limitation is

In situ real-time monitoring techniques for membrane fouling in food, biorefinery and biotechnology industries

Membrane fouling is a constant challenge of membrane processes in separation and purification of organic, biomass originated compounds in food, biorefining and biotechnology industries. It persists due to the complexity and high fouling tendency of the bio-based streams and may result in a decrease of filtration capacity, rejection alteration, reduction of membrane lifetime and increase of operati

Parameterized Yields of Semivolatile Products from Isoprene Oxidation under Different NOx Levels: Impacts of Chemical Aging and Wall-Loss of Reactive Gases

We developed a parametrizable box model to empirically derive the yields of semivolatile products from VOC oxidation using chamber measurements, while explicitly accounting for the multigenerational chemical aging processes (such as the gas-phase fragmentation and functionalization and aerosol-phase oligomerization and photolysis) under different NOx levels and the loss of particles and gases to c

Synthesis, Morphological, and Electro-optical Characterizations of Metal/Semiconductor Nanowire Heterostructures

In this letter, we demonstrate the formation of unique Ga/GaAs/Si nanowire heterostructures, which were successfully implemented in nanoscale light-emitting devices with visible room temperature electroluminescence. Based on our recent approach for the integration of InAs/Si heterostructures into Si nanowires by ion implantation and flash lamp annealing, we developed a routine that has proven to b

High Yield of GaAs Nanowire Arrays on Si Mediated by the Pinning and Contact Angle of Ga

GaAs nanowire arrays on silicon offer great perspectives in the optoelectronics and solar cell industry. To fulfill this potential, gold-free growth in predetermined positions should be achieved. Ga-assisted growth of GaAs nanowires in the form of array has been shown to be challenging and difficult to reproduce. In this work, we provide some of the key elements for obtaining a high yield of GaAs

Optimisation and integration of membrane processes in the beverage industry

Potential applications of membrane technology for the beverage industry will be presented by two case studies. The focus of the first case study is on the clarification and concentration of fruit juice. A novel combination of a centrifuge with ultrafiltration for the clarification will be discussed together with the combination of an evaporator combined with reverse osmosis for the concentration.

Supersonic jets of hydrogen and helium for laser wakefield acceleration

The properties of laser wakefield accelerated electrons in supersonic gas flows of hydrogen and helium are investigated. At identical backing pressure, we find that electron beams emerging from helium show large variations in their spectral and spatial distributions, whereas electron beams accelerated in hydrogen plasmas show a higher degree of reproducibility. In an experimental investigation of

Ultrafast THz Probe of Photoinduced Polarons in Lead-Halide Perovskites

We study the nature of photoexcited charge carriers in CsPbBr3 nanocrystal thin films by ultrafast optical pump-THz probe spectroscopy. We observe a deviation from a pure Drude dispersion of the THz dielectric response that is ascribed to the polaronic nature of carriers; a transient blueshift of observed phonon frequencies is indicative of the coupling between photogenerated charges and stretchin

Understanding the complex metallic element Mn. II. Geometric frustration in β−Mn, phase stability, and phase transitions

In the preceding paper [D. Hobbs, J. Hafner, and D. Spišák, Phys. Rev. B 68, 014407 (2003)], we have started an ab initio spin-density-functional study of the complex structural and magnetic phase behaviors of Mn by a detailed investigation of α−Mn. It was shown that the complex crystalline and noncollinear antiferromagnetic structures are the results of the conflicting tendencies to maximize simu
