Baumwolle als Faserverstärkung
(2023)
Jedes Jahr landen große Mengen Textilen auf Deponien oder in der thermischen Verwertung. Ein Teil dieser Abfälle könnte allerdings auch als Rohstoffe für Verbundwerkstoffe dienen. Baumwollfasern eignen sich etwa als Verstärkungsfasern, die die mechanischen Eigenschaften von biobasierten Kunststoffen steigern. Durch die Nutzung solcher Abfallströme können in Zukunft kostengünstig und biobasiert Materialien verstärkt werden.

The potential of mangrove as a food source in Riau
(2023-12-28)
Mangrove fruit has been utilized as a food by people in several regions in Indonesia, especially as traditional food. Information about the potential and benefits of mangrove fruit is still limited. There is not much information regarding physico-chemical properties of mangrove fruit as a potential food source. This study aims to gather and review various scientific information related to the potential of mangrove fruit and its use as foodstuff. This information can be used as a basis to conduct further research ...

Mechanical Characterization and Simulation of Wood Textile Composites (WTC) supported by Digital Image Correlation (DIC)
(2023-05-30)
Wood Textile Composites (WTC) based on willow wood fabrics and polypropylene were produced using a hot compacting process in order to open up new and innovative areas of applications for wood. Due to their attractive and variable design, the WTCs are to be used in areas with a high visual impact, for example as a facade element. In tensile and 3-point bending tests, it was shown that the mechanical properties of WTC are strongly dependent on the heterogeneous structure of the composite. Both strength and elongation ...

How are psychodynamic conflicts associated with personality functioning? A network analysis
(2023-04-19)
Personality functioning and psychodynamic conflicts are central constructs in psychoanalytic theories of psychopathology as well as in many psychodynamic treatment models. Although there has been a longstanding conceptual discussion on how they relate to each other, empirical evidence on this question is still scarce. In this study, we explore the associations between psychodynamic conflicts and levels of structural integration (which can be used synonymously with personality functioning) by means of a partial ...

Engaging diverse experts in the global science-policy interface: Learning experiences from the process of the IPBES Values Assessment
(2023-06-30)
This longitudinal study explores evidence of learning and reflexivity among experts involved in the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Values Assessment from 2018 to 2022. As part of an online survey administered at yearly intervals, experts self-reported their views on: i) the aims they attributed to the Values Assessment, ii) their epistemic worldviews, iii) the definition of the multiple values of nature, and iv) their personal learning experiences in the ...

Microstructure of an additively manufactured Ti-Ta-Al alloy using novel pre-alloyed powder feedstock material
(2023-05-01)
Binary Ti-Ta and ternary Ti-Ta-Al alloys attracted considerable attention as new potential biomaterials and/or high-temperature shape memory alloys. However, conventional forming and manufacturing technologies of refractory based titanium alloys are difficult and cost-intensive, especially when complex shapes are required. Recently, additive manufacturing (AM) emerged as a suitable alternative and several studies exploited elemental powder mixing approaches to obtain a desired alloy and subsequently use it for complex ...

In-situ full-field deformation analysis of injection-molded microcellular polycarbonate according to foam morphology patterns
(2023-06-02)
Deformation behavior of microcellular foam materials are sensitive to microstructural details. Therefore, the distinctive foam morphology patterns of foam injection-molded Polycarbonate are identified. These morphology patterns are investigated regarding their cell size, distance between cells, cell density, density reduction, homogeneity of cell size distribution, sphericity of cells and cell volume. Consequently, the predefined foam morphologies, the resulting modulus of elasticity and the elongation at break are ...

Optimization on the manufacturing process of fried instant corn noodle using response surface methodology
(2023-07-31)
Instant corn noodles can be manufactured using the air drying and frying process. The objective of this study was to determine the optimum process parameters and emulsifier concentration to produce instant corn noodles from 100% corn flour with relatively good quality characteristics using a cooking-forming single screw extruder. This study consisted of two stages, namely the determination of corn noodles with the fastest cooking time using emulsifier concentrations of 0, 0.5, 1, and 1.5% from the weight of corn ...

Traditional Seafood Product Purchase Through E-Commerce: The Impact of Perceived Risk and Benefit to Consumers’ Intention to Buy
(2023-07-31)
Traditional seafood products in Indonesia are also very diverse, influenced by ethnicity and eating habits. However, the problem is the low level of consumption of seafood products in Indonesia. There is a limited number of traditional seafood products have entered the e-commerce due to the lack of knowledge about consumer demand. To boost the purchase of traditional seafood product, consumers’ perception need to be explored as it plays prominent role in a successful food product. The aims of this research are to ...
