III-V semiconductor nanowires have attracted extensive research interests over the past few decades due to their unique geometry and great potential for promoting new functionalities in future electronics, light-emitting diodes and solar cells. However, in order to push this technology beyond the laboratory level, it is essential to combine it with the current Si-based semiconductor industry for a
This study was undertaken to investigate the impact of culture pH (4.5–6.5) and temperature (32–37 °C) on the stress resilience of Lactobacillus reuteri DSM 17938 during freeze-drying and post freeze-drying exposure to low pH (pH 2)and bile salts. Response-surface methodology analysis revealed that freeze-drying survival rates Ncells after drying/Ncells before drying*100 were linearly related to p
Three different, state-of-the-art biogeochemical models are adapted in order to quantify the carbon dioxide (CO2), nitrous oxide (N 2O), and methane (CH4) exchanges between arable lands and the atmosphere. Biome-BGC and MOD17 are validated using the long-term measurement results from Hegyhátsál tall tower site (Western Hungary). After a simple bias correction, it was found that Biome-BGC is capabl
This presentation gives an overview of a peer learning model and academic support intervention named SI-PASS (Supplemental Instruction – Peer Assisted Study Schemes) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult”, normally introductory, courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular e
We study the notion of anonymous credentials with Publicly Auditable Privacy Revocation (PAPR). PAPR credentials simultaneously provide conditional user privacy and auditable privacy revocation. The first property implies that users keep their identity private when authenticating unless and until an appointed authority requests to revoke this privacy, retroactively. The second property enforces th
Digital volume correlation analysis of time-resolved X-ray microtomography scans acquired during in situ triaxial compression of Green River shale cores provided time series of 3-D incremental strain fields that elucidated evolving deformation processes by quantifying microscopic strain localization. With these data, we investigated the impact of mechanical anisotropy on microscopic strain localiz
Perovskite based photovoltaic devices are popularised by the rapid increase in their efficiencies. Understanding the fundamental physics and chemistry processes occurring upon excitation is key. We monitored the temporal evolution of the population and depopulation dynamics of various electronic states in FA0.85MA0.15PbI2.55Br0.45 by means of ultrafast transient absorption spectroscopy in the visi
Software Engineering activities are information intensive. Research proposes Information Retrieval (IR) techniques to support engineers in their daily tasks, such as establishing and maintaining traceability links, fault identification, and software maintenance. We describe an engineering task, test case selection, and illustrate our problem analysis and solution discovery process. The objective o
The molecular weight distribution and the viscosity of water-soluble polysaccharides isolated from carrots were investigated after different types of heat-treatment, commonly used when preparing food. The materials studied were blanched, boiled, microwaved and canned. Freezing, without any heat-treatment, was used as a reference process. The water soluble polysaccharides were isolated using two di
Primary aluminium production is energy- and GHG-intensive in which electrolysis is by far the most energy- and GHG-intensive process. This paper’s aim is to study the effects on (1) primary energy use, (2) GHG emissions and (3) energy and CO2 costs when energy end-use efficiency measures are implemented in the electrolysis. Significant savings in final and primary energy use, GHG emissions and ene
How the avian sex chromosomes first evolved from autosomes remains elusive as 100 million years (My) of divergence and degeneration obscure their evolutionary history. The Sylvioidea group of songbirds is interesting for understanding avian sex chromosome evolution because a chromosome fusion event ∼24 Ma formed "neo-sex chromosomes" consisting of an added (new) and an ancestral (old) part. Here,
For the realization of graphene-based electronic and optic devices, the functionalization of this material becomes essential. Graphene doping through intercalation and tuning the chemical potential is one among other promising concepts. Intercalation of germanium is particularly interesting in view of its ambipolar doping behavior. Both p- and n-type doped graphene and their doping levels were ide
We show that the 2.4σ signal of the leptonic flavor violating (LFV) Higgs boson decay h→μτ, as observed by the CMS Collaboration recently, can be explained by a certain class of two-Higgs doublet models that allow controllable flavor-changing neutral current with a minimal number of free parameters. We postulate that (i) the alignment limit is maintained, which means the lightest neutral scalar (h
The aim of this dissertation is to analyse value creation in a rural tourism development project. In order to analyse value creation, I investigate how participants of a rural tourism development project define and understand uniqueness of that particular rural area as a lever to developing a touristic offer. The empirical research question guiding this work is: How do participants of a rural tour
This presentation discusses an ongoing research project that aims to collect data about the practice of information search. It seeks to learn more about different ways in which tourist information is collected at different stages of a journey. Speaking to tourism planners and reading tourism research, it seems as if the digitalization of information has completely changed tourists’ information sea
Among the layers of a plant community, the canopy has the most important hydrological function in water circulation. Understanding the canopy’s inner structure and its relationship to water transport is fundamental for the functional mechanisms of the vegetation canopy. Using an artificial rainfall simulator to supply three levels of rainfall intensity, the interception of rainfall by the canopy w
