Metaphysics in the Work of Charles Darwin
(Simon Baumgartner, Thimo Heisenberg , Sebastian Krebs, 2013)
It is not hard to see how two visions of nature are intertwined in Darwin’s Journal of Researches: one vision, the province of romantic authors depicting the sentiments awakened by certain landscapes, the other, the domain ...
Romanticism, Alexander von Humboldt and the distinction of “Natur” and “Geist”
(2017-02-28)
Alexander von Humboldt is often considered a decisive figure in establishing clear methodological standards in modern natural sciences. But many people forget that he was a true Romanticist in his descriptions of nature ...
New polymer electrolytes for all-solid-state lithium batteries
(2019-10-18)
Los electrolitos poliméricos se presentan como buenos candidatos para reemplazar a los electrolitos líquidos convencionales en dispositivos de almacenamiento de energía. Los polímeros presentan grandes ventajas tales como ...
Boiling heat transfer of multiple impinging water jets on a hot rotary cylinder
(2022-02-10)
The aim of this study is to make a better understanding of the multiple water impinging jets quenching technique in order to make further research in the area of enhancing the mechanical properties of steel by understanding ...
Vortex Filament Equation for a Regular Polygon in the Hyperbolic Plane
(Springer, 2022-02)
The aim of this paper is twofold. First, we show the evolution of the vortex filament equation (VFE) for a regular planar polygon in the hyperbolic space. Unlike in the Euclidean space, the planar polygon is open and both ...
Mechatronic Model of a Compliant 3PRS Parallel Manipulator
(MDPI, 2021-12-28)
Compliant mechanisms are widely used for instrumentation and measuring devices for their precision and high bandwidth. In this paper, the mechatronic model of a compliant 3PRS parallel manipulator is developed, integrating ...
Mobility system for extreme terrains on the Moon for NASA's challenge
(2022-02-10)
The objective of this full project is to design and develop a novel mobility system to be applied on extreme terrains of the Moon for NASA’s challenge, although in this report I will be only talking about the design part ...
Vegetation of the Cantabrian-Atlantic dunes: ecological drivers and biodiversity patterns at multiple scales
(2020-11-25)
En la presente tesis se realiza un estudio de las comunidades vegetales de las dunas costeras atlánticas desde Galicia hasta el sur de Francia. Se analizan la diversidad taxonómica, funcional y filogenética a niveles alfa ...
Comparative Study of Strategies for Enhancing the Performance of Co3O4/Al2O3 Catalysts for Lean Methane Combustion
(MDPI, 2020-07-08)
Spinel-type cobalt oxide is a highly active catalyst for oxidation reactions owing to its remarkable redox properties, although it generally exhibits poor mechanical, textural and structural properties. Supporting this ...
Optimization of the 2PRU-1PRS Parallel Manipulator Based on Workspace and Power Consumption Criteria
(MDPI, 2021-08-24)
In the last few years, parallel manipulators are being increasingly studied and used for different applications. The performance of parallel manipulators is very sensitive to the geometric parameters, so it is essential ...
