Experimentelle Untersuchung zur Mehrphasenströmung in öleingespritzten Mehrphasenschraubenspindelpumpen
(2020-02-18)
Für die Förderung von Gemischen mit hohen Gasanteilen erfolgt die Entwicklung eines neuen Kühlkonzepts, indem das Prozessfluid in flüssiger Phase extern in die Förderkammer einer Mehrphasenpumpe eingespritzt wird. Neben der Regulierung des Thermomanagements trägt dies zur Spaltabdichtung bei, so dass der effektiv geförderte Volumenstrom steigt. Zur Untersuchung der Thermo‐ und Fluiddynamik einer solchen Mehrphasenpumpe wird ein transparentes Förderkammermodell der Pumpe mit externer Fluideinspritzung entwickelt. Das ...

Sustainability assessment of activated carbon from residual biomass used for micropollutant removal at a full-scale wastewater treatment plant
(2020-05-29)
Activated carbon (AC), used for removal of organic micropollutants in European wastewater treatment plants (WWTPs), is usually produced from non-renewable resources that need to be transported over long distances. Utilising local residual biomass as a raw material may be advantageous in terms of sustainability. This study investigated the environmental and energy balances of using biowaste and biomass from landscape management for micropollutant removal at a commercial scale WWTP. Both residual biomasses were processed ...

Mode properties of telecom wavelength InP-based high-(Q/V) L4/3 photonic crystal cavities
(2020-05-13)
We present finite-difference time domain simulations and optical characterizations via micro-photoluminescence measurements of InP-based L4/3 photonic crystal cavities with embedded quantum dots (QDs) and designed for the M1 ground mode to be emitting at telecom C-band wavelengths. The simulated M1 Q-factor values exceed 106, while the M1 mode volume is found to be 0.33 × (λ/n)3, which is less than half the value of the M1 mode volume of a comparable L3 cavity. Low-temperature micro-photoluminescence measurements ...

Indicators of Affect Dynamics: Structure, Reliability, and Personality Correlates
(2020-07-21)
Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these might convey little unique information beyond mean level and general variability of emotions. Our study extends the evidence for the construct validity of IADs by investigating ...

Morphologically similar but not closely related: the long-sporedspecies of Subulicystidium (Trechisporales, Basidiomycota)
(2020-06-06)
Species boundaries and geographic distribution of corticioid fungi (resupinate Basidiomycota) are often poorly known. Ourrecent study onSubulicystidiumshowed that species diversity in this genus is at least twice as high as previously recognized. Thisre-estimation of the species diversity was based on a study of only a part of the genus. The present study sheds light on molecularand morphological diversity of three more species. We generated 27 ITS and 24 28S nuclear ribosomal DNA sequences from 49specimens labelled ...

Psychosocial Interventions for Newly Arrived Adolescent Refugees: A Systematic Review
(2020-02-25)
Adolescent refugees are confronted with multiple developmental, psychological, and social challenges after flight. Psychosocial interventions are therefore necessary to support adolescents during the first period after arrival in a receiving country and to avoid negative long-term consequences. Unfortunately, little is known about the types and the effects of such interventions provided during this time. This systematic review aimed to synthesize research about psychosocial interventions for refugee youth during the ...

Using CFD Modelling to Relate Pig Lying Locations to Environmental Variability in Finishing Pens
(2020-03-03)
The purpose of this research was to determine which environmental factors within the pen space differ between the locations where pigs choose to lie and areas they avoid. Data on external weather engconditions and the construction parameters for an existing commercial finishing pig building were input into a Dynamic Thermal (DT) model generating heat flow and surface temperature patterns in the structure and these were then input into a Computational Fluid Dynamics (CFD) model to generate data on the theoretical ...

Best, Heinrich/Higley, John (Hrsg.): The Palgrave Handbook of Political Elites, 698 S., Palgrave Macmillan, London 2018.
(2020-01-16)
Heinrich Best (Friedrich-Schiller-Universität Jena) und John Higley (University of Connecticut) haben mit dem knapp 700 Seiten umfassenden Handbuch eine bemerkenswerte Bestandsaufnahme der Forschung zu politischen Eliten vorgelegt. Beide Herausgeber haben sich über mehrere Jahrzehnte hinweg mit diesem Thema beschäftigt. Politische Eliten sind dabei nicht in einem engen Sinne ausschließlich als politische Entscheidungsträger zu verstehen, sondern werden weiter definiert als alle Personen, die Einfluss auf politische ...

Mismatch of Glucose Allocation between Different Life Functions in the Transition Period of Dairy Cows
(2020-06-13)
Simple Summary
The reasons for the development of diseases in the transition period of dairy cows are manifold and highly farm- and cow-specific. Nevertheless, links exist between the degree of negative energy balance (NEB) and disease susceptibility, which suggest a mutual adverse relationship between immune and productive functions. Glucose is the most essential fuel and precursor for both immune cells and mammary epithelial cells (MEC). While the delivery of glucose by the intermediary metabolism is not always ...

The Potential Influence of Organic Food Consumption and Intention-Behavior Gap on Consumers’ Subjective Wellbeing
(2020-05-18)
This paper applied a self-administered survey to investigate the impact of organic food behavior and the intention-behavior gap in organic food consumption (OIBG) on consumers’ subjective wellbeing including physical, emotional, social and intellectual dimensions. The survey was carried out with 385 consumers. Furthermore, the study conducted a food test to explore the different impacts of organic and conventional food samples on the mental and physical conditions of consumers’ wellbeing applying a psychological ...
