Redoxtrons – An experimental system to study redox processes within the capillary fringe
(2023-02-02)
Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air-filled porosities (ε), oxygen concentration (O₂) and soil redox potential (Eₕ) are interrelated soil variables within active biogeochemical domains such as the CF. We investigated the impact of water table (WT) rise and drainage in an undisturbed topsoil and subsoil sample taken from a Calcaric Gleysol for a period of 46 days. We merged 1D (Eₕ and matric potential) and 2D (O₂) systems to monitor at ...

Die Gewährleistung von Krankheitshilfen bei asylsuchenden Menschen: Zweiklassenmedizin in Deutschland?
(2020-09-22)
Hintergrund
Es gibt im Bereich des Asylbewerberleistungsgesetzes (AsylbLG) zwei Möglichkeiten der Leistungsgewährung mit praktischer Relevanz für die Gesundheitsversorgung (abhängig von der Voraufenthaltszeit): die Grundleistungen und die Leistungen in besonderen Fällen analog zum Sozialgesetzbuch (SGB) XII.
Methodik
Die Sekundärdatenanalyse untersucht das Leistungsgeschehen im Krankheitsfall bei den Leistungsempfängern nach dem AsylbLG beim Forschungsdatenzentrum der Statistischen Ämter des Bundes und der Länder. ...

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 ...

Microsatellites from Fosterella christophii (Bromeliaceae) by de novo transcriptome sequencing on the Pacific Biosciences RS platform
(2016)
• Premise of the study: Microsatellite markers were developed in Fosterella christophii (Bromeliaceae) to investigate the genetic diversity and population structure within the F. micrantha group, comprising F. christophii, F. micrantha, and F. villosula. • Methods and Results: Full-length cDNAs were isolated from F. christophii and sequenced on a Pacific Biosciences RS platform. A total of 1590 high-quality consensus isoforms were assembled into 971 unigenes containing 421 perfect microsatellites. Thirty primer sets ...

Spectral composition of low-coherence interferograms at high numerical apertures
(2019-04-11)
Interference signals in coherence scanning interferometry at high numerical apertures and narrow bandwidth illumination are spectrally broadened. This enables phase analysis within a spectral range much wider than the spectral distribution of the light emitted by the light source. Consequently, different surface features can be resolved depending on the wavelength used for phase analysis of the interference signals.
In addition, the surface topography itself affects the spectral composition of interference signals ...

Influence of pre-drying storage time on essential oil components in dried hops (Humulus lupulus L.)
(2020-10-15)
BACKGROUND
It is well known that duration of pre-drying storage impacts on hop quality. However, little knowledge exists regarding its actual effects on valuable hop components. To investigate these effects, fresh hop cones were stored for 5 or 24 h and dried for 210 min at 65 °C thereafter. Furthermore, to understand the effect of freezing hop cones on the essential oil content, both fresh and stored samples were frozen before and after drying.
RESULTS
The results from gas chromatography analysis show an increase ...

Feeding practices of pre‐school children and associated factors in Kathmandu, Nepal
(2019-11-03)
Background
In developing countries such as Nepal, many children aged below 3 years do not grow at a sufficiently high rate and are vulnerable to micronutrient deficiencies (e.g. vitamin A). Challenges to child nutrition can result from poverty, unhealthy traditional practices, inadequate caring and feeding practices. The present study aimed to assess the feeding practices of pre‐school children and their associated factors.
Methods
A cross‐sectional study was carried out in pre‐schools located in Kathmandu district ...

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 ...

Analysis and Validation of Varied Simulation Parameters in the Context of Thermoplastic Foams and Special Injection Molding Processes
(2023-04-28)
The simulation solutions of different plastic injection molding processes are as multifaceted as the field of injection molding itself. In this study, the simulation of a special injection molding process, which generates partially foamed integral components, was parameterized and performed. This partial and physical foaming is realized by a defined volume expansion of the mold cavity. Using the injection molding simulation software Moldex 3D, this so-called Pull and Foam process was digitally reconstructed and ...

Model selection, adaptation, and combination for transfer learning in wind and photovoltaic power forecasts
(2023-03-14)
There is recent interest in using model hubs – a collection of pre-trained models – in computer vision tasks. To employ a model hub, we first select a source model and then adapt the model for the target to compensate for differences. There still needs to be more research on model selection and adaption for renewable power forecasts. In particular, none of the related work examines different model selection and adaptation strategies for neural network architectures. Also, none of the current studies investigates the ...
