Green food consumption: Studies on consumers’ purchase intentions and the intention-behaviour gap in the Chinese context
(2021)
With the growing problem of the global environment and exposure to various food safety incidents, consumers are increasingly concerned about the environment as well as the safety and quality of food products. Therefore, growing calls for safe, healthy, environmentally friendly, and sustainable food consumption have been growing. As one of China’s most successful ecolabelling programs, green food has shown great potential for further expansion among Chinese food consumption. This doctoral research has taken consumers’ ...

Referring nouns in name-informing quotation: A copula-based approach
(Universität OsnabrückenHumboldt-Universität zu Berlin, 2020)
In name-informing constructions like "The phenomenon is called a “sun halo”", the noun mentioned in the quotation (a “sun halo”) adopts a referring interpretation, as indicated by the determiner. As an account, we claim predicates like call to introduce a copular relation, which is the source of referring uses of nominals in name-informing quotation: To call y “n” entails that y is an n. Two copula types are argued to be covertly contained in name-informing constructions, an identificational copula and an equative ...

Development of CFD-Based Tip Clearance Loss and Deviation Models for Axial-Flow Turbines
(2020-01)
Accurate loss correlations are crucial for reliable turbine performance predictions with low-fidelity tools. However, conventional tip clearance models disregard some important loss effects, e. g. from the relative motion between blades and endwall, and their natural spanwise distributions, which are valuable for through-flow methods. The objective of this thesis is the development of more realistic tip clearance models by means of high-fidelity CFD simulations, which capture all three-dimensional flow effects and ...

Homeoffice - eine Transformation der Arbeitswelt. Systematischer Überblick und Perspektiven der Gestaltung
(2021-05)
Coronakrise und Homeoffice scheinen zwei Seiten einer Medaille zu sein. Durch das Homeoffice lassen sich die Corona-bedingten Kontakteinschränkungen besonders erfolgreich umsetzen. Auf der einen Seite ist die Rede vom damit einhergehenden Beitrag zur Eindämmung der Infektionsrisiken. Auf der anderen Seite lässt sich so die Kontinuität wirtschaftlicher Prozesse sicherstellen. Homeoffice wird mit weiteren Vorteilen in Verbindung gebracht, die vielfach als Fortschritt auf dem Weg zu einer modernen Arbeitswelt gesehen ...

Annual industrial and commercial heat load profiles: modeling based on k-Means clustering and regression analysis
(2021-03-19)
An accurate method to predict annual heat load profiles is fundamental to many studies, e.g., preliminary design or potential studies on renewable heating systems. This study presents a method to predict annual heat load profiles with a daily resolution for industry and commerce, based on an analysis of 800 natural gas load profiles (≥ 1.5 GWh/a). To derive heat load profiles, these natural gas load profiles are normalized and those with a potentially non-linear relationship between heat demand and natural gas ...

Nutritional, antioxidant properties and polyphenol content of quinoa (Chenopodium quinoa Willd.) cultivated in Iran
(2021-05-25)
The quinoa is pseudocereal plant that has nutritional value. Recently, It was cultivated in iran because of water crisis. This study aimed to assess the physicochemical and antioxidant properties of quinoa cultivated in Iran for the first time. The macronutrients and energetic value, polyphenol, total phenol content and DPHH of quinoa were measured. Some B group vitamin, the free fatty acid profile was assessed by HPLC and GC-mass separately. The trace elements were also evaluated by ICP. The amounts of dry matter, ...

Can calcium sprays alleviate jelly seed in mango fruits?
(2020-03-27)
Jelly seed is a major challenge in mango production leading to enormous losses in the value chain. This internal fruit disorder is characterised by disintegration of cells, consistency of jelly and broken cells. Calcium plays an important role in enhancing tissue stability and firmness thus reducing cell disintegration. A two-year field study was conducted in Embu County, Kenya using ‘Van Dyke’ cultivar trees of approximately 10 years old. The objective of the study was to investigate the effect of varied sources of ...

On the Impact of Texture and Grain Size on the Pseudoelastic Properties of Polycrystalline Fe–Ni–Co–Al–Ti Alloy
(2020-05-08)
The effects of thermomechanical treatments on crystallographic texture and grain size evolution and their impact on the pseudoelastic properties in Fe41–Ni28–Co17–Al11.5–Ti2.5 (at.%) were studied in the present paper. The results show that cold rolling leads to brass-type texture in this alloy, which is typical for low stacking fault energy materials. Thermal treatments up to 1300 °C were conducted and it is shown that the presence of β-phase helps to control grain growth. After the dissolution of the secondary phase ...

Characterisation of productivity and diseases affecting dairy goats in smallholder systems of Greater Thika Region, Kenya
(2020-11-18)
The current cross-sectional study aimed at characterising the productivity and diseases affecting dairy goats kept by smallholder farmers in three sub-counties in Thika Region, Kenya. Standard questionnaires were administered to 240 farmers through face-to-face interviews and the outputs were analysed using descriptive and inferential statistics. The farmers mainly kept crosses of Toggenburg (45.9 %), Kenyan Alpine (29.5 %) and Saanen (17.4 %) dairy goats. The average dairy goat flock size was 4.5 (range 1–23) and ...

Kurzarbeit im Korsettt der Versicherungslogik: Es ist Zeit, die "Bazooka" neu zu justieren
(2021-06)
Ehre wem Ehre gebührt, aber Olaf Scholz hat die Kurzarbeit nicht erfunden, wie es ihm im Eifer des Wahlkampfs herausrutschte. Es besteht zwar kein Zweifel, dass er als Arbeitsminister in der Finanz- und Wirtschaftskrise 2008/09 dieses Instrument kreativ und effektiv nutzte, erfunden haben es aber die Badener:innen schon in der Tabakkrise 1909. Dabei diente dieses Instrument in Baden nicht nur als Brücke der fairen Einkommenssicherung, sondern auch als Brücke zu einem nachhaltigen Strukturwandel: Statt weiter am Anbau ...
