Morphologically similar but not closely related: the long-sporedspecies of Subulicystidium (Trechisporales, Basidiomycota)
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 ...
JOBS Program Germany for health promotion among the unemployed in the community setting with institutions for employment promotion (JobsProgramDtl): study protocol for a randomized controlled trial
Background Compared to the employed, the unemployed are characterized by a substantially worse health status, particularly with regards to mental health. At the same time, conventional offers of prevention and health promotion rarely reach the unemployed. The JOBS Program is a health promotion program that combines job application training with elements of social learning theory and self-efficacy. Randomized field studies in the USA and Finland found significant positive effects on reintegration into the labor market ...
Iterative feature detection of a coded checkerboard target for the geometric calibration of infrared cameras
The geometric calibration of cameras becomes necessary when images should be undistorted, geometric image information is needed or data from more than one camera have to be fused. This process is often done using a target with a checkerboard or circular pattern and a given geometry. In this work, a coded checkerboard target for thermal imaging cameras and the corresponding image processing algorithm for iterative feature detection are presented. It is shown that, due in particular to the resulting better feature ...
Animal Welfare Consequences of Organic Boar Fattening and Occurrence of Boar Taint on Five Commercial Farms
Simple Summary The usual castration of male fattening pigs is under discussion, especially in organic farming, because of the negative effects on the pig’s welfare and integrity. Nevertheless, it is feared that boars show more aggressive and mounting behaviours, resulting in stress, painful injuries and lameness, and that their meat has an unpleasant odour/taste (called “boar taint”). Therefore, it was examined to which extent these concerns come true under commercial organic conditions. Additionally, influences ...
Influence of Microstructure and Defects on Mechanical Properties of AISI H13 Manufactured by Electron Beam Powder Bed Fusion
Electron beam powder bed fusion (E-PBF) is a well-known additive manufacturing process. Components are realized based on layer-by-layer melting of metal powder. Due to the high degree of design freedom, additive manufacturing came into focus of tooling industry, especially for tools with sophisticated internal cooling channels. The present work focuses on the relationships between processing, microstructure evolution, chemical composition and mechanical properties of a high alloyed tool steel AISI H13 (1.2344, ...
Psychosocial Interventions for Newly Arrived Adolescent Refugees: A Systematic Review
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 ...
The Dark Triad and Deception Perceptions
The present cross-sectional study (N = 205) tested the hypothesis that the Dark Triad traits – narcissism, Machiavellianism, and psychopathy – and the PID-5 maladaptive personality traits – Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism – are associated with specific deception-related perceptions: perceived cue-based deception detectability, perceived deception production ability, and perceived deception detection ability. Participants completed personality and deception measures in an ...
Using CFD Modelling to Relate Pig Lying Locations to Environmental Variability in Finishing Pens
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.
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
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 ...
