High Consistency Silicone Rubber Foams
(2024-04-23)
Silicone elastomers are high-performance plastics. In the extrusion process, only high-consistency silicone rubbers were used. In order to reduce the cost and weight, silicone rubbers can be foamed during processing. In this study, high-consistency silicone rubber is processed with different physical and chemical blowing agents. The resulting reaction kinetics, as well as the mechanical and morphological properties, had been investigated and compared with each other. This showed that the chemical blowing agent ...

Pathways toward the Use of Non-Destructive Micromagnetic Analysis for Porosity Assessment and Process Parameter Optimization in Additive Manufacturing of 42CrMo4 (AISI 4140)
(2024-02-20)
Laser-based powder bed fusion of metals (PBF-LB/M) is a widely applied additive manufacturing technique. Thus, PBF-LB/M represents a potential candidate for the processing of quenched and tempered (Q&T) steels such as 42CrMo4 (AISI 4140), as these steels are often considered as the material of choice for complex components, e.g., in the toolmaking industry. However, due to the presence of process-induced defects, achieving a high quality of the resulting parts remains challenging in PBF-LB/M. Therefore, an extensive ...

Enhancing crop-livestock systems: Unveiling the impact of leaf stripping on maize hybrid yield in Sundarbazar-Lamjung, Nepal
(2024-03-12)
In local maize agro-ecosystems in Nepal leaf stripping is, historically, practiced as a source of fodder for livestock. However, its effects on hybrid maize have not been studied. The aim of this study was to determine how defoliation below the cob affects the grain and fodder production of hybrid maize and what value the stripped leaves have as fodder for ruminants. Seven hybrid maize cultivars were evaluated for their response to leaf stripping in a randomized complete block design with three replications in ...

A Literature Review on Solid Waste Management and Disposal Behavior at the Base of the Pyramid
(2024-03-10)
Consumer behavior in disposing of products has substantial consequences for the environment that affect all of us. Waste management is a major challenge faced by many developing countries, underlining the relevance of this literature review. Even when academia tries to shed light on this field, it often fails to consider that waste management must be approached differently in less developed countries, which differ dramatically from advanced countries, especially with regard to consumers’ behavioral characteristics. ...
