Jenseits des Horizonts
(Schwabe Verlag, 2022)
Im Folgenden ist deshalb zu überlegen, was diesseits und was jenseits des kartografischen Horizonts damaliger Menschen lag, wie sich die Relationen zwischen beiden Zonen in Abhängigkeit von Zeit, visualisiertem Raum und vorhandenem Wissen verschoben und welche Relevanz dem jenseitig Gelegenen dabei zukam. Es ist also nach den Dynamiken am Horizont zu fragen, dem Suchen und Überschreiten, den Akten des Stabilisierens und Flexibilisierens, den erkenntnistheoretischen Voraussetzungen und den kulturellen Praktiken, die ...

Consumers ’ perception of sustainable packaging in the food industry: An online experiment
(2022-01)
Consumers evaluate products and make purchasing decisions based on packaging and its sustainable aspects. This research investigated how different packages and their quality, eco-friendliness, expensiveness, and convenience affected consumers’ intentions to purchase. Our sample comprised 299 French consumers of muesli cereals. We conducted an online choice experiment to analyze and measure consumers’ perception of sustainable packaging, comparing three distinct experimental groups. Findings revealed that quality and ...

Analysis and Method Selection of a Measure-Correlate-Predict Methodology for a Digital Wind Buoy
(2022)
The determination of the site-specific wind conditions has a significant influence on the development and use of offshore wind energy. Lower uncertainties of wind potential result in cost-effective project financing. Floating lidar systems (FLS) or wind lidar buoys have become increasingly common in recent years as a measuring technology for the determination of offshore wind resource. However, due to harsh offshore environmental conditions, offshore measurements with FLS are prone to reliability issues which might ...

A Novel Thermo-Mechanical Processing Route Exploiting Abnormal Grain Growth in Heusler-Type Co–Ni–Ga Shape Memory Alloys
(2022-10-04)
Heusler-type Co–Ni–Ga shape memory alloys attracted significant scientific attention owing to excellent superelasticity in single-crystalline state. However, due to pronounced anisotropy, polycrystalline Co–Ni–Ga suffers from transformation-induced constraints at grain boundaries and, thus, premature failure upon thermo-mechanical loading. The present study reports on a novel thermo-mechanical processing route. Hot rolling followed by solution-annealing promotes abnormal grain growth, eventually leading to high-performance ...

Cooling rate as a process parameter in advanced roll forming to tailor microstructure,mechanical and corrosion properties of EN AW 7075 tubes
(2022-12-14)
The effects of solution heat treatment parameters and quench media as a processing tool for tailoring microstructure, mechanical and corrosion properties in roll forming of EN AW 7075 alloy were studied. The highest yield stress and ultimate tensile strength were obtained for the specimens quenched in water, while the air-cooled specimens exhibited inferior mechanical properties. Microstructural analysis of specimens showed that except water-quenched specimens, the parts cooled/quenched in oil, in direct contact with ...

On the Friction Stir Processing of Additive-Manufactured 316L Stainless Steel
(2022)
The novel combination of friction stir processing (FSP) and additive manufacturing (AM) is studied herein. Laser-based powder bed fusion of metals (PBF-LB/M) is used to establish 316 L stainless steel with a bimodal microstructure. Upon FSP, the as-built bimodal microstructure with an average grain size of 179 μm is transformed into the unimodal microstructure containing ultrafine grains with an average grain size of 1.2 μm. Results obtained by mechanical testing reveal that after FSP; the hardness, the yield point, ...

ORDEN ENCRIPTADO
(2022-12-09)
Los monasterios femeninos fueron un equipamiento imprescindible dentro del panorama urbano y arquitectónico de las ciudades virreinales. Constituyeron además auténticas unidades urbanas con autonomía y complejidad propia. La presente conferencia visibiliza el orden urbano generativo y esboza las características fundantes de la espectacular arquitectura de uno de los monasterios más importantes de Latinoamérica: el Monasterio de Santa Catalina de Siena de Arequipa. /Gonzalo Ríos Vizcarra Arquitecto por la Universidad ...

Oxide Modified Iron in Electron Beam Powder Bed Fusion - From Processability to Corrosion Properties
(2022-03-07)
Additive manufacturing (AM) processes are not solely used where maximum design freedom meets low lot sizes. Direct microstructure design and topology optimization can be realized concomitantly during processing by adjusting the geometry, the material composition, and the solidification behavior of the material considered. However, when complex specific requirements have to be met, a targeted part design is highly challenging. In the field of biodegradable implant surgery, a cytocompatible material of an application-adapted ...
