Renewable Energy Integration for Steam Supply of Industrial Processes—A Food Processing Case Study
(2020-05-16)
This study highlights the CO2,e -emission reduction potentials and related economic consequences for changing steam generation from fossil to renewable. Seven different utility concepts are developed, including a steam accumulator for load management. Peculiarities for the integration of biogas boilers, biomass-fuelled boilers, electrode steam boilers, biomethane-fuelled solid oxide fuel cells, micro gas turbine, solar energy systems, heat pumps and steam accumulators into a steam system with fluctuating steam demand ...

Role of SSD1 in Phenotypic Variation of Saccharomyces cerevisiae Strains Lacking DEG1-Dependent Pseudouridylation
(2021-08-15)
Yeast phenotypes associated with the lack of wobble uridine (U34) modifications in tRNA were shown to be modulated by an allelic variation of SSD1, a gene encoding an mRNA-binding protein. We demonstrate that phenotypes caused by the loss of Deg1-dependent tRNA pseudouridylation are similarly affected by SSD1 allelic status. Temperature sensitivity and protein aggregation are elevated in deg1 mutants and further increased in the presence of the ssd1-d allele, which encodes a truncated form of Ssd1. In addition, ...

Vertrauen und Führung im Kontext digitaler Arbeit
(2020-04-16)
Der vorliegende Beitrag der Zeitschrift „Gruppe. Interaktion. Organisation. (GIO)“ untersucht die Relevanz von Vertrauen zwischen Führungskraft und Mitarbeiter im Kontext der Digitalisierung und kommt zu dem Ergebnis, dass Vertrauen in Zukunft noch bedeutsamer wird. Der Beitrag gelangt zu dieser Erkenntnis, indem er die psycho-sozialen Auswirkungen der Digitalisierung auf organisationaler Ebene identifiziert und systematisch die möglichen Wirkzusammenhänge zu Vertrauen analysiert. Die Analyse ergibt, dass sich die ...

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 ...

Prediction of biomass and N fixation of legume-grass mixtures using sensor fusion
(2021-01-21)
European farmers and especially organic farmers rely on legume–grass mixtures in their crop rotation as an organic nitrogen (N) source, as legumes can fix atmospheric N, which is the most important element for plant growth. Furthermore, legume–grass serves as valuable fodder for livestock and biogas plants. Therefore, information about aboveground biomass and N fixation (NFix) is crucial for efficient farm management decisions on the field level. Remote sensing, as a non-destructive and fast technique, provides ...

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.
