Soil–climate contribution to DNDC model uncertainty in simulating biomass accumulation under urban vegetable production on a Petroplinthic Cambisol in Tamale, Ghana
(2020-03-24)
Crop yield simulation using the Denitrification–Decomposition (DNDC) model can help to understand key bottlenecks for improved nitrogen (N) use efficiency and estimate greenhouse gas (GHG) emissions in West African urban vegetable production. The DNDC model was successfully calibrated using high‐resolution weather records, information on management practices and soils, and measured biomass accumulation and N uptake by amaranth (Amaranthus L.), jute mallow (Corchorus olitorius L.), lettuce (Lactuca sativa L.), and ...

Investment Barriers and Labeling Schemes for Socially Responsible Investments
(2020-02-21)
Given the increasing role of socially responsible investing (SRI), but still limited participation of individual (i.e. small, retail) investors, the objective of this study is twofold: (i) We aim to identify investment barriers regarding SRI for individual investors and analyze to what extent these barriers vary across different investor groups. (ii) We analyze to what extent sustainability or transparency labels can help to overcome these barriers. To this end, we empirically analyze data from a survey and a stated ...

Compiling Measurement Invariant Short Scales in Cross‐Cultural Personality Assessment Using Ant Colony Optimization
(2020-04-26)
Examining the influence of culture on personality and its unbiased assessment is the main subject of cross‐cultural personality research. Recent large‐scale studies exploring personality differences across cultures share substantial methodological and psychometric shortcomings that render it difficult to differentiate between method and trait variance. One prominent example is the implicit assumption of cross‐cultural measurement invariance in personality questionnaires. In the rare instances where measurement ...

Spatio-Temporal Dynamics of Algae and Macrophyte Cover in Urban Lakes: A Remote Sensing Analysis of Bellandur and Varthur Wetlands in Bengaluru, India
(2020-11-23)
Rapid urbanization processes and indiscriminate disposal of urban wastewaters are major causes for anthropogenic lake-sediment deposition and eutrophication. However, information about the spatial and temporal variation of macrophyte and phytoplankton distribution as indicators for water contamination is limited. To gain insights into the dynamics, we analyzed lake-cover changes of Bellandur and Varthur Lake in the S-Indian megacity of Bengaluru for the post-rainy seasons of the years 2002–2019. Supervised maximum ...

Impact of Pus1 Pseudouridine Synthase on Specific Decoding Events in Saccharomyces cerevisiae
(2020-05-07)
Pus1-dependent pseudouridylation occurs in many tRNAs and at multiple positions, yet the functional impact of this modification is incompletely understood. We analyzed the consequences of PUS1 deletion on the essential decoding of CAG (Gln) codons by tRNAGlnCUG in yeast. Synthetic lethality was observed upon combining the modification defect with destabilized variants of tRNAGlnCUG, pointing to a severe CAG-decoding defect of the hypomodified tRNA. In addition, we demonstrated that misreading of UAG stop codons by a ...

On Multivariate Bernstein Polynomials
(2020-08-21)
In this paper, we first revisit and bring together as a sort of survey, properties of Bernstein polynomials of one variable. Secondly, we extend the results from one variable to several ones, namely—uniform convergence, uniform convergence of the derivatives, order of convergence, monotonicity, fixed sign for the p-th derivative, and deduction of the upper and lower bounds of Bernstein polynomials from those of the corresponding functions.

Comparison between Hyperspectral Imaging and Chemical Analysis of Polyphenol Oxidase Activity on Fresh-Cut Apple Slices
(2020-06-29)
The assessment of the quality of fresh-cut apple slices is important for processing, storage, market value, and consumption. Determination of polyphenol oxidase activity (PPO) in apples is critical for controlling the quality of the final product (i.e., dried apples and juices). Hyperspectral imaging (HSI) is a nondestructive, noncontact, and rapid food quality assessment technique. It has the potential to detect physical and chemical quality attributes of foods such as PPO of apple. The aim of this study was to ...

Performance of Thermo-Mechanically Processed AA7075 Alloy at Elevated Temperatures—From Microstructure to Mechanical Properties
(2020-07-03)
This study focuses on the high temperature characteristics of thermo-mechanically processed AA7075 alloy. An integrated die forming process that combines solution heat treatment and hot forming at different temperatures was employed to process the AA7075 alloy. Low die temperature resulted in the fabrication of parts with higher strength, similar to that of T6 condition, while forming this alloy in the hot die led to the fabrication of more ductile parts. Isothermal uniaxial tensile tests in the temperature range of ...

Material Flow Cost Accounting in Developing Countries: A Systematic Review
(2020-07-04)
This study aims to provide a better understanding of material flow cost accounting (MFCA) application in developing countries, which are characterized by rapid structure transformation leading to serious environmental problems. By systematically reviewing the existing literature, our analysis of 28 studies from nine developing countries (China, Indonesia, Iran, Malaysia, South Africa, Sri Lanka, Thailand, the Philippines, and Vietnam) shows that MFCA research has primarily focused on Asian developing countries. ...

Automatically Detected Pecking Activity in Group-Housed Turkeys
(2020-11-04)
Simple Summary
Cannibalism is one of the biggest welfare issues of today’s turkey husbandry. We hypothesized that changes in pecking activity might indicate imminent cannibalism. Therefore, in this pilot study a newly developed automatic pecking activity detection was validated, and continuously applied to gain information about pecking activity of group-housed turkeys during the rearing phase and before a cannibalistic outbreak. The pecking object was used by turkeys the whole recording time. Activity on the object ...
