Influence of the degree of crystallinity and the surface free energy on the adhesion properties of different PLA/PBS blends in multicomponent injection molding
(2020-01-10)
Biocomposites made of biodegradable polymers have grown in interest due to their environmentally friendliness, considering that non-biodegradable polymers waste conduces to pollution, displaying high environmental impact in climatic changes. Therefore, in the presented study, biodegradable Poly (lactic acid) (PLA) and poly (butylene succinate) (PBS) were investigated as a series of PLA/PBS melt-blending compounds with the weight ratios of 50/50, 60/40, 70/30, 80/20 and 90/10. In a two-component injection molding ...

Consumer acceptability of rice-like grains made from cassava (Manihot esculenta Crantz) and corn (Zea mays)
(2020-11-29)
Rice is one of the most important crops in Asia. There are several crops that can be utilized as an alternative to rice. This can help reduce the burden of rice importation and improve food security. The purpose of this study was to develop a consumer acceptable rice-like grains from cassava and corn. A total of 220 combinations of rice-like grains from different cultivars of cassava (Binulak, Lakan 1, Lakan 2, Rajah 4) and corn (IPB Var 6, IPB Var 8, IPB Var 11, IPB Var 13) were developed. Most acceptable combinations ...

An Exploration on Factors Influencing Certified and Farm-Saved Seed Use: A Case Study in Turkish Wheat Farming
(2020-11-29)
Seeds are an important input for wheat-growing, as is the case for all crop production. The type and quality of seed in crop production are the first condition for productivity and accordingly certified wheat seed use is being encouraged by the government since 2005 in Turkey. This study examined the factors affecting the certified seed and farmer (farm)-saved seed use in wheat farming in Turkey. The result of the analyses showed that there is a significant difference between farmers using certified seed and farm-saved ...

Seasonal variation in mycoflora associated with asymptomatic maize grain from small-holder farms in two provinces of South Africa
(2020-11-27)
Seed quality plays an important role in the establishment of healthy crop stands. The aim of this study was to identify the mycoflora associated with maize grain collected over two growing seasons, one experiencing severe drought, from small-holder farms across KwaZulu-Natal (KZN) and the Eastern Cape (EC), two important provinces with maize producing small-holder farmers in South Africa. Asymptomatic maize ears were collected at harvest during two maize growing seasons from farms located in Hlanganani (KZN), ...

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 ...

A review of soil fertility management communication in sub-Saharan Afrika
(2021-02-12)
In sub-Saharan Africa (SSA), declining soil fertility is among the factors a ecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socioeconomic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM ...
