The dissertation examines how German universities respond to student diversity in the context of the widening participation agenda and how variations in organizational responses can be explained. As a theoretical framework, the study builds on Scandinavian institutionalism (Czarniawska & Joerges, 1996) that seeks to understand how organizations interpret institutional pressures and how these interpretations affect their daily organizational practices (Boxenbaum & Strangaard Pedersen, 2009; Sa...

Liquid water is one of the key components of life on this planet. Moreover, its unique properties and anomalies make it highly relevant for several processes in physics, biology and chemistry. The fascinating characteristics and anomalies are by no means restricted to liquid water at ambient conditions. Thus, pressurised water at high temperatures, so-called hydrothermal water, is essential for heat and mass transfer processes in Earth’s upper mantle and exerts a significant influence on geoc...

In this article we discuss the contribution of digitalisation for equal participation in higher education. Its potential is often postulated, but accessibility is seldom examined in this context. Despite the challenges and difficulties created in the summer term of 2020, this semester has provided a great opportunity to collect data on digital teaching, as face‐to‐face teaching needed to be transformed into digital teaching. Based on two surveys conducted in the summer of 2020, current practi...

In today’s globalized world with dynamic processes of political, social, and societal change (Mergner et al., 2019) the university should be a place of encounter between people with different (cultural) backgrounds. The learning arrangement presented here therefore initiates intercultural exchange and aims to help students see diversity as an asset rather than a challenge (Roos, 2019). To this end, an intercultural project was initiated at TU Dortmund in Germany in 2017. In the context of dif...

Das Konzept der Umweltgerechtigkeit (UG) bezieht sich inhaltlich auf die Beziehung zwischen der sozialen Lage einer Person, ihrer lokalen Umwelt und Gesundheit. Dabei wird die sozialräumliche Verteilung von Umweltbelastungen und -ressourcen in den Blick genommen. Somit vereint das Umweltgerechtigkeitskonzept ökologische und soziale Anforderungen an den Siedlungsraum. Anknüpfungspunkte für die Stadtplanung und -entwicklung finden sich in vielen informellen Zielsetzungen und formalen Regelwerke...

This study investigates the interaction between identity preservation and linguistic integration of Eritrean immigrants in the French speaking part of Switzerland. The focus is put on Eritrean refugees and asylum seekers, who have been in Switzerland between six months to three years. This research is guided by three main research questions: a) what are their language use? b) what are their language attitudes? c) what factors play a role in language learning motivation? In terms of motivation...

Heutzutage ist die numerische Modellierung des Transportverhaltens innerhalb von Quantenbauelementen für die Analyse und das Design moderner Komponenten der Nanoelektronik, Hochfrequenztechnik und Terahertz-Technik unabdingbar. Neben der Analyse des stationären Regimes erlangt dabei insbesondere die Erfassung transienter Phänomene unter Berücksichtigung von Wechselwirkungsmechanismen eine große Bedeutung. Während sich Ansätze auf Basis von Greenschen-Funktionen mittlerweile zur Analyse des st...

Biomolecular condensates consisting of proteins and nucleic acids can serve critical biological functions, so that some condensates are referred as membraneless organelles. They can also be disease-causing, if their assembly is misregulated. A major physicochemical basis of the formation of biomolecular condensates is liquid–liquid phase separation (LLPS). In general, LLPS depends on environmental variables, such as temperature and hydrostatic pressure. The effects of pressure on the LLPS of ...

Biocatalysis offers a broad spectrum of possible ecological and economic advantages over conventional chemical catalysis processes, e.g., lower energy consumption and high enantio selectivity. The focus of this work is on gas-liquid reactions. These are of great importance in the chemical and biochemical industry and subject of current research since they are often limited by mass transfer or show low selectivity. Different suitable biocatalytically gas-liquid reaction systems were tested in ...

The implementation of traditional sensors is a drawback when investigating mass transfer phenomena within microstructured devices, since they disturb the flow and reactor characteristics. An Arduino based slider setup is developed, which is equipped with a computer-vision system to track gas–liquid slug flow. This setup is combined with an optical analytical method allowing to compare experimental results against CFD simulations and investigate the entire lifetime of a single liquid slug with...

We report programmable receptors for the imaging-based analysis of 5-methylcytosine (5mC) in user-defined DNA sequences of single cells. Using fluorescent transcription-activator-like effectors (TALEs) that can recognize sequences of canonical and epigenetic nucleobases through selective repeats, we imaged cellular SATIII DNA, the origin of nuclear stress bodies (nSB). We achieve high nucleobase selectivity of natural repeats in imaging and demonstrate universal nucleobase binding by an engin...

Collaborative robots have to adapt its motion plan to a dynamic environment and variation of task constraints. Currently, they detect collisions and interrupt or postpone their motion plan to prevent harm to humans or objects. The more advanced strategy proposed in this article uses online trajectory optimization to anticipate potential collisions, task variations, and to adapt the motion plan accordingly. The online trajectory planner pursues a model predictive control approach to account fo...

The combination of an alkoxy and an amino function combined in one silane is rarely found due to the difficult synthesis and isolation.[1] However, this combination offers unique opportunities to investigate the influence of steric requirements or the size of a metal on the structure or reactivity of alkoxysilylamides towards electrophiles by varying the metallating reagent (n-butyllithium or di-n-butylmagnesium) or the organo group on the amino function. For this purpose, we synthesized two ...

Triphasic gas-liquid-liquid slug flow systems have great application potential in flow chemistry and are normally generated with a double T-junction where the continuous phase and one disperse phase form a two-phase flow and the second disperse phase is added at the second junction. This design is limited to high disperse phase ratios when a regular and uniform flow is desired. The use of coaxial contactors allows overcoming most of these restrictions. The slug generation, stability, and regu...

Recent evidence suggests that during the first year of life, a preference for consonant information during lexical processing (consonant bias) emerges, at least for some languages like French. Our study investigated the factors involved in this emergence as well as the developmental consequences for variation in consonant bias emergence. In a series of experiments, we measured 5-, 8-, and 11-month-old French-learning infants orientation times to a consonant or vowel mispronunciation of their ...

n fused layer modeling (FLM) manufacturing technology, there is an increased demand for semi-crystalline materials due to their favorable mechanical properties, such as high strength and toughness. The reasons for their limited use are process-related residual stresses and reduced interlayer bonding, resulting in component distortion, warping and poor strength. Addressing these problems, this paper presents the development and implementation of a rotary print head that enables local laser pre...

We tackle two limitations of standard instrumental variable regression in experimen- tal and observational studies: restricted estimation to the conditional mean of the outcome and the assumption of a linear relationship between regressors and outcome. More flexible regres- sion approaches that solve these limitations have already been developed but have not yet been adopted in causality analysis. The paper develops an instrumental variable estimation proce- dure building on the framewor...

We investigate an optimal control problem governed by the evolution of a rate-independent system in finite dimensions. The rate-independent system is determined by a (possibly) non-convex energy, which contains the controllable, external load, and a dissipation potential, which is assumed to be positively homogenous of degree one. Under the several di˙erent concepts of solutions for these rate-independent systems, we bear on the so-called normalized parametrized BV solutions and prove the exi...

This article analyzes the stochastic aspects of a tontine using a Gompertz distribution. In particular, the probabilistic and demographic risks of a tontine investment are examined. The expected value and variance of tontine payouts are calculated. Both parameters increase with age. The stochastic present value of a tontine payout is compared with the present value of a fixed annuity. It is shown that only at very high ages the tontine is more profitable than an annuity. Finally, the demograp...
