Untersuchung von Gussporen in einer Aluminium-Gusslegierung mit der Computertomographie
(2022-04)
In dieser Arbeit wird das Schädigungsverhalten einer Aluminium-Gusslegierung anhand von zweidimensionalen und dreidimensionalen Verfahren untersucht. Dabei liegt das Hauptaugenmerk auf innenliegenden Gussdefekten wie Gas- und Schrumpfungsporen. Die Schädigungsentwicklung unter schwingender Belastung, sowie der Einfluss auf die Mikrostruktur und die mechanischen Eigenschaften sowie die Wechselwirkung verschiedener Gussdefekte werden dabei untersucht. Insbesondere wird der beim Versagensverhalten entscheidende Einfluss ...

Agripreneurial drive among women shea butter processors in Kwara State, Nigeria: the motivating factors and efficiency
(2022-10-12)
This study examined agricultural entrepreneurship among women shea butter processors in Kwara State Nigeria. It assessed their motivation factors, level of efficiencies, determinants of output and challenges faced in the entrepreneurial drive by the women. Primary data, collected using a semi-structured questionnaire, were collected from randomly selected 120 shea butter women processors. The data obtained were analysed with descriptive statistics, index ranking and the stochastic frontier function. The results showed ...

La cortesía verbal en textos medievales españoles: universalidad, historicidad y tradicionalidad
(Universidad de Sevilla, 2022)
La pragmática histórica y el análisis conversacional histórico exploran las tareas comunicativas y sus transformaciones en las comunidades lingüísticas y culturales de diferentes épocas (cf. Schrott 2011, 2012, 2016, Jucker/Taavitsainen 2010). Para cumplir con sus tareas comunicativas y, en particular, con las normas de cortesía los hablantes recurren a patrones y rutinas que moldean las interacciones verbales. Estas tradiciones discursivas, con su saber cultural, son una directriz cardinal para el habla cortés. La ...

The Austro Modern
(2021)
The countries of Central Europe cannot simply be understood as catching up with Western modernization. Rather, the article shows how technical developments proceeded in the car factories Lohner in Vienna and Austro-Daimler in Wiener Neustadt, and how the light and powerful gasoline engine drove aircraft construction (the Taube by Etrich) and airship construction. Austria was the leader in aircraft construction around 1910. The creative milieu in Vienna is evident from the fact that the headquarters of the Lohnerwerke ...

Taste masking in vegan food processing with natural substitutes
(2022-12-29)
Climate change, sustainability issues, increased risks of meat diet on both ecology and human health cause changes in the eating habits of individuals. Plant-based foods supply protein sources with health-promoting compounds. The bitterness of plant-based foods is a challenge for both food manufacturers and consumers. So far, artificial taste blockers, salt, sugar, and fat have been applied to mask the bitterness of plant-based products. However, people are conscious of "clean labelling " and "natural " ingredients ...

The potential of cabbage waste extract as a bio-stimulant for enhancing growth, biochemical constituents, and oil quality of thyme (Thymus vulgaris)
(2022-12-29)
Thyme (Thymus vulgaris L.) is an important cultural aromatic plant, whose herb and essential oils (EOs) have been used in many industrial and medicinal applications. Herb and EO yields are often negatively influenced by various factors, so it is important to keep finding new growing procedures that increase the quantitative content of herbs and EOs. Therefore, this paper is focused on the effects of applying cabbage extract (CE) at different concentrations on morphological parameters, mineral contents, total ...

Physiological response of some canola genotypes to proline concentration under saltwater irrigation conditions
(2022-12-29)
A pot experiment was conducted in split-split plot design with four replications to study proline foliar application with 0, 50, and 100 ppm and four canola genotypes cultivated under irrigation of tap water and salinity irrigation water at 4500 ppm and their interactive effects on growth characters, yield, and yield components and some chemical composition of the canola plants. Results indicated that a higher salinity level at 4500 ppm reduced growth, photosynthetic pigments, yield, and yield attributes as well as ...

The effects of weather factors on titrating acids accumulation in sweet cherry fruits
(2022-12-29)
During the fruit formation, the weather conditions have a decisive influence on the organic acids accumulation. In the context of global climate change, this issue has become new. The study of the titrated acids content in sweet cherry fruits was carried out for 12 years. Cherry fruits of three ripening groups were selected for the study. The average and strong correlation dependence between 11 weather factors and the titrated acids content for the sweet cherries varieties of early, middle, late ripening periods were ...

Do spatial climate messages increase pro-environmental engagement? Evidence from a survey experiment on public transport
(2022)
Using a survey experiment among a special sample composed of art house cinema visitors, we investigate whether spatial climate messages increase subjects’ willingness to pay for an inclusion of public transport fares in cinema tickets as well as their willingness to use public transport in case such a combined ticket is introduced. Based on previous findings, we expect emphasizing the positive impact of public transport usage on the local level to have a greater effect on subjects’ preferences for public transport ...
