A Comparative Analysis of Residential Care: A Five-Country Multiple Case-Design Study
(2021-12-13)
Background
Despite a global policy push toward the advancement of family- and community-based care, residential care for children and youth remains a relevant and highly utilized out-of-home care option in many countries, fulfilling functions of care and accommodation as well as education and treatment.
Objective
As part of a larger project involving five European countries (Finland, Germany, Italy, Lithuania, and Spain), the objective was “to map” the context and content of residential care in each country, thereby ...

Net-mineralization of organic matter and greenhouse gas emissions from Quebracho tannin-enriched manure applied to acidic and alkaline soils
(2021-07-09)
Background
Mitigation strategies to reduce greenhouse gas emissions, ammonia volatilization, and nitrate leaching from agriculture are important for the management of environmental pollution and climate change. Tannins, which are water-soluble polyphenolic compounds, were found to reduce emissions in animal husbandry systems when supplemented to ruminant diets.
Aim
Two laboratory incubation experiments were conducted to investigate the effects of Quebracho tannin-enriched manure on carbon (C) and nitrogen (N) ...

A monolithic approach toward coupled electrodynamic–thermomechanical problems with regard to weak formulations
(2021-11-11)
Weak formulations of boundary value problems are the basis of various numerical discretization schemes. They are classically derived applying the method of weighted residuals or a variational principle. For electrodynamical and caloric problems, variational approaches are not straightforwardly obtained from physical principles like in mechanics. Weak formulations of Maxwell’s equations and of energy or charge balances thus are frequently derived from the method of weighted residuals or tailored variational approaches. ...

Measurement and analysis of residual stresses and warpage in fiber reinforced plastic and hybrid components
(2021-02-16)
Glass/carbon fiber reinforced plastic (GFRP/CFRP) and hybrid components have attracted increasing attention in lightweight applications. However, residual stresses induced in the manufacturing process of these components can result in warpage and, eventually, negatively affect the mechanical performance of the composite structures. In the present work, GFRP, CFRP, GFRP/steel and CFRP/steel hybrid components were manufactured through the prepreg-press-technology always employing the same process parameters. The residual ...

Role of Nanoimprint Lithography for Strongly Miniaturized Optical Spectrometers
(2021-01-11)
Optical spectrometers and sensors have gained enormous gimportance in metrology and information technology, frequently involving the question of size, resolution, sensitivity, spectral range, efficiency, reliability, and cost. Nanomaterials and nanotechnological fabrication technologies have huge potential to enable an optimization between these demands, which in some cases are counteracting each other. This paper focuses on the visible and near infrared spectral range and on five types of optical sensors (optical ...

Agro-ecological landuse transformation in oasis systems of Al Jabal Al Akhdar, northern Oman
(2021-04-08)
The millenia-old oasis systems in the Western Hajar Mountains of Northern Oman have received widespread attention as models of sustainable irrigated agriculture in hyperarid Arabia. Given Oman’s rampant urbanization, growing scarcity of water and skilled labour, we quantified chances in water use, land use, and land cover between 2007 and 2018 using a rare time-series approach of detailed GIS-based crop mapping. Results from satellite image analysis and comprehensive ground truthing showed that urban areas grew from ...

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
(2021-02-01)
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 ...

Prevalence and utilization of company integration management in Germany: Results of the 2018 BiBB/BAuA survey of employed persons
(2021-09-09)
Objectives
This secondary analysis aims to investigate the implementation of the legally required company integration management (“BEM”) in case of an incapacity for work of at least six weeks and to identify predictors.
Methods
Database is the representative randomized 2018 BIBB/BAuA Employment Survey of 20 012 employed persons in Germany.
Results
Of the 1367 employees entitled to company integration management, 40% received an offer from their employer and 27% accepted it. In the public sector, half of those ...

Feed Quality and Feeding Level Effects on Faecal Composition in East African Cattle Farming Systems
(2021-02-22)
Simple Summary
Sub-Saharan cattle are often exposed to a feed reduction caused by a seasonal lack of forage, which was investigated in the first experiment. The supplementation of roughage-based diets with sweet potato vine silage and urea molasses blocks is recommended to improve the growth of heifers, in particular, which was investigated in the second experiment. Across all data, the fungal C/bacterial C ratio was positively related to nitrogen and negatively to neutral detergent fiber concentrations in feces. ...
