The Holy Land Geography as Emotional Experience
(De Gruyter, 2021-06-08)
In this paper,we evaluate various medieval cartographic and diagrammatic representations of the Holy Land. The analysis focuses particularly on the religious dimensions of these representations and their potential for making pilgrimage accessible, creating religious symbolism and exciting spiritual emotions. The leading hypothesis is that medieval mapmakers introduced special technical features into maps and similar cartographic representations to deepen religious emotions and to stimulate intense sensory responses ...

Dynamic Tensile Deformation of High Strength Aluminum Alloys Processed Following Novel Thermomechanical Treatment Strategies
(2020-05-14)
Herein, the effects of a very recently introduced novel thermomechanical process route on the microstructural evolution and dynamic tensile deformation behavior of two different precipitation hardenable aluminum alloys, i.e., AA6082 and AA7075, are studied. The investigated materials are hot formed and quenched in differently tempered tools to reveal the influence of cooling rate. Microstructure analysis is conducted to study the influences of different cooling strategies on the microstructure evolution and prevailing ...

Effect of Compositional Variation Induced by EBM Processing on Deformation Behavior and Phase Stability of Austenitic Cr-Mn-Ni TRIP Steel
(2020-01-24)
Electron beam melting (EBM) is an established powder bed-based additive manufacturing process for the fabrication of complex-shaped metallic components. For metastable austenitic Cr-Mn-Ni TRIP steel, the formation of a homogeneous fine-grained microstructure and outstanding damage tolerance have been reported. However, depending on the process parameters, a certain fraction of Mn evaporates. This can have a significant impact on deformation mechanisms as well as kinetics, as was previously shown for as-cast material. ...

On the Impact of Texture and Grain Size on the Pseudoelastic Properties of Polycrystalline Fe–Ni–Co–Al–Ti Alloy
(2020-05-08)
The effects of thermomechanical treatments on crystallographic texture and grain size evolution and their impact on the pseudoelastic properties in Fe41–Ni28–Co17–Al11.5–Ti2.5 (at.%) were studied in the present paper. The results show that cold rolling leads to brass-type texture in this alloy, which is typical for low stacking fault energy materials. Thermal treatments up to 1300 °C were conducted and it is shown that the presence of β-phase helps to control grain growth. After the dissolution of the secondary phase ...

Research communication has been gaining public attention in recent years. Therefore, medievalists also need to focus on the transfer of their research topics to the public both within and outside the university. Based on current political demands calling for a change in communication culture, the article first of all deals theoretically with two different concepts of research communication, by distinguishing between forms of translation and those of popularization. Numerous public events, exhibitions, and cooperative ...

Influences on the mechanical properties of SRCs in a combined compacting and back injecting process
(2022-03-03)
In this research paper, the effects of the combined compacting and back-injection process to produce back-injected self-reinforced composites on the mechanical properties of the self-reinforced composites (SRCs) are investigated. For this purpose, the parameters barrel temperature, time of injection and holding pressure were varied for the back injection. Tensile and bending tests were carried out on the SRCs. The results show that the mechanical properties depend to a large extent on the process parameters. The ...

JOHN F. C. TURNER EN PERÚ
(2022-12-16)
La conferencia, basada en la colaboración con Turner y una labor de reactivación de memoria urbana en barriadas turnerianas, presenta aspectos de su legado poco conocidos y dignos de servir de base para nuevas lecturas del urbanismo peruano y en particular de los barrios autoconstruidos de Lima. Invita a explorar la visión holística de Turner con miras a lo que puede aportar para imaginar el desarrollo colectivamente gestionado y sostenible de una multitud de barrios que hoy se expanden en zonas naturales y sobre ...

DEL QHAPAQ ÑAN A LAS RUTAS COLONIALES
(2023-03-17)
En un mismo territorio se instalan primero el Tahuantinsuyo y luego el Virreinato del Perú, y, sobre la base de ambos, desde la Independencia, la República del Perú.
Los cambios estructurales en lo social, económico y político en el paso de una civilización autóctona a una economía y sociedad coloniales se expresan también en las diferentes estrategias de ocupación del territorio.
La presente conferencia esboza la gestación y transformación de la estructura vial peruana en sus momentos constitutivos como base y ...

PIURA
(2023-03-31)
Desde su fundación española en 1532, el medio geográfico, las transformaciones económicas y una planificación insuficiente marcan una relación conflictiva entre la ciudad y su entorno, caracterizado por el bosque seco tropical renovado de modo cíclico por El Niño. Víctor Velezmoro presenta el devenir histórico de una ciudad que se sofoca ante la ausencia de un plan que permita enfrentar la dicotomía de su ubicación en el desierto y a la vez sujeta a inundaciones.
