Warum man Weihnachten erfinden müsste ...
(2020)
„Wenn es Weihnachten nicht längst gäbe, so müsste man es erfinden.“ Dieses dem US-amerikanischen Autor und Journalisten Eric Sevareid zugeschriebene Zitat behauptet zu Recht die Ausnahmestellung von Weihnachten. Kein anderes Fest der christlichen Kulturtradition weckt so viel an Erwartungen, Gefühlen und Hoffnungen in den Menschen.

Small-scale milk production systems in Colombia: a regional analysis of a potential strategy for providing food security
(2020-11-29)
Colombia tiene una diversidad agroecológica que favorece la implementación de sistemas de producción de leche. La producción lechera es una parte integral de la economía rural y contribuye positivamente a la nutrición e ingresos de las familias. El objetivo de este estudio fue clasificar los sistemas de producción de leche en la comunidad de El Peñón (Municipio de Sibate, Colombia), y analizar los resultados en relación con el concepto de seguridad alimentaria. El estudio evaluó componentes relacionados con los niveles ...

Rechtsverträgliche und qualitätszentrierte Gestaltung für "KI made in Germany"
(2020-02-21)
Künstlich intelligente (KI) Systeme erfreuen sich immer größerer Beliebtheit. Insbesondere smarte persönliche Assistenten (SPAs) von Amazon, Google und vielen weiteren verzeichnen ein stetiges Marktwachstum. Den vielfältigen Potenzialen dieser KI-Systeme stehen jedoch auch zahlreiche Risiken gegenüber. Berichte von Datenpannen und -lecks häufen sich und haben bei Nutzern eine zunehmende Skepsis zur Folge, was zu einem gespaltenen Bild von KI in der Gesellschaft beiträgt. Diesem Problem stellt sich das Forschungsprojekt ...

Reasons for consuming rasi as a staple food for the Cireundeu indigenous people: a qualitative study
(2021-09-29)
Rasi (made from cassava) are used as staple food by the Cireundeu indigenous people. This food culture is considered different from the food culture of Indonesian people who generally make rice as their staple food. Therefore, this study aimed to show the reasons Cireundeu indigenous people consume rasi as their staple food. This qualitative research was conducted in Cireundeu Village, Cimahi City, West Java Province, Indonesia. Data was collected from the Cireundeu indigenous people through in-depth interviews and ...

Access to the learning material enhances learning by means of generating questions: Comparing open- and closed-book conditions
(2020)
Generating questions referring to the learning material is a powerful learning strategy. The present study investigated potential mechanisms behind this effect. Students (N=231) read a text and then generated questions referring to the text in three conditions: (1) open-book (i.e., text accessible), (2) closed-book (i.e., text inaccessible), and (3) cued closed-book (i.e., text inaccessible but keywords provided). After one week, students’ knowledge gain was larger in the open-book and cued closed-book conditions ...

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment
(2021-11-30)
Surface treatments characterized by rapid heating and cooling (e.g. laser hardening) can induce very steep residual stress gradients in the direct vicinity of the area being treated. These gradients cannot be characterized with sufficient accuracy by means of the classical sin2Ψ approach applying angle-dispersive X-ray diffraction. This can be mainly attributed to limitations of the material removal method. In order to resolve residual stress gradients in these regions without affecting the residual stress equilibrium, ...

Factors influencing technology adoption among smallholder farmers: a systematic review in Africa
(2022-01-25)
Smallholder agriculture has been identified to be critical in the creation of employment, improving food security and improving the economy. However, smallholder agriculture in Africa is characterised by a low production level which has been linked to the limited use of technologies. Several factors influence the adoption of technologies among smallholder farmers in Africa. This systematic literature review focuses on the factors influencing technology adoption among smallholder farmers in Africa and identified 128 ...

Use of total mixed ration citrus pulp silage as a new feeding strategy for growing lambs
(2022-01-26)
This study was conducted to evaluate the effects of using total mixed ration silage based on citrus pulp on feed intake, growth performance, serum metabolites and ruminal fermentation of growing female lambs. For this purpose, sixty-eight female Zel lambs (5-6-months) with an initial body weight of 20.65 ± 3.71 kg were randomly divided into two equal groups (n=34). Two isonitrogenous and isoenergetics diets were formulated based on corn silage (TMRC) and citrus pulp silage (TMRPS), respectively. To prepare TMRPS, ...

Technical efficiency of paddy farming in West Java: a combination of synthetic and organic fertilisers versus conventional farming
(2022-02-08)
In developing countries, agriculture’s burden is not just ensuring enough food for the people but also securing net income for the farmers to alleviate poverty and to conserve the environment at the same time. Consumption shift towards staples, particularly during economic crisis or pandemic, requires a policy that could make food growers respond to the demand appropriately. Initially, from soil science, an argument asserts that mixing organic and synthetic fertilisers can increase yield/productivity and be safe for ...

Analysis of the nutritional and productive behaviour of dairy cows under three rotation bands of pastures, Pichincha, Ecuador
(2021-12-08)
This research was carried out on Pennisetum clandestinum-based pastures to identify the effect of three (3) types of stocking methods with similar forage allowance (8.2 kg of dry matter for 100 kg of live weight) but differing by the occupation times of the rotations (3 h, 24 h, and continuous) on the behaviour and the production of dairy cows. The experimental scheme consisted in three herds of four Holstein Friesian cows grazing three paddocks, one per rotation type, for one week and replicated three times in a ...
