The Messinian stromatolites of the Sierra del Colmenar (Western Mediterranean): facies characterization and sedimentological interpretation
2018
A representative outcrop of the Messinian stromatolites belonging to the Terminal Carbonate Complex unit, from the northern sector of the Bajo Segura basin (Caja de Ahorros del Mediterraneo section, Sierra del Colmenar, SE Spain) has been studied. Here, we present a detailed analysis of the architecture, external morphology, and internal morphology in order to reconstruct the environmental and palaeoecological conditions for their growth. The stromatolites macrostructure consists of a continuously doming type morphology (build up and sheets areas).These developed close to the coast and acted as a palaeogeographic barrier, reducing physical stress, channeling the erosive effect of water and …
Experimental calibration and implications of olivine-melt vanadium oxybarometry for hydrous basaltic arc magmas
2018
The strong dependence of vanadium partitioning between olivine and silicate melt (DVOl-M) on redox conditions (fO2) can be used as sensitive oxybarometer in magmatic systems. Here we extend the experimental database on DVOl-M, obtained so far at high temperatures (mainly above 1250 °C), to lower temperatures that are typical for island-arc basalts. Crystallization experiments were performed using a composition from Mutnovsky volcano (Kamchatka), and the investigated temperature, pressure, and oxygen fugacity ranges were 1025–1150 °C, 0.1 and 0.3 GPa, and ΔQFM of –0.5 to +3.2, respectively. The water content in melts ranged from 0.6 to ∼6.5 wt% H2O. The data demonstrate a strong negative cor…
Improved composite materials for rechargeable lithium metal polymer batteries
1999
Abstract The performance of several polymer electrolytes for lithium metal batteries for electric vehicle applications are reported. The best performing electrolyte is the composite PEO 20 LiCF 3 SO 3 –γLiAlO 2 , which was prepared by a solvent-free procedure. It showed coulombic efficiency values of the lithium deposition–stripping process of 94%–96%. Electrochemical tests of lithium polymer battery (LPB) prototypes based on a 3 V LiMn 2 O 4 composite cathode material laminated together with the PEO 20 LiCF 3 SO 3 –γLiAlO 2 electrolyte gave promising results for electric vehicle applications. Even under non-optimized battery design, the prototypes delivered, at the C/3 rate and at 94°C, 40…
Atomic Layer Deposition of Spinel Lithium Manganese Oxide by Film-Body-Controlled Lithium Incorporation for Thin-Film Lithium-Ion Batteries
2013
Lithium manganese oxide spinels are promising candidate materials for thin-film lithium-ion batteries owing to their high voltage, high specific capacity for storage of electrochemical energy, and minimal structural changes during battery operation. Atomic layer deposition (ALD) offers many benefits for preparing all-solid-state thin-film batteries, including excellent conformity and thickness control of the films. Yet, the number of available lithium-containing electrode materials obtained by ALD is limited. In this article, we demonstrate the ALD of lithium manganese oxide, LixMn2O4, from Mn(thd)3, Li(thd), and ozone. Films were polycrystalline in their as-deposited state and contained le…
Short-term e-cigarette vapour exposure causes vascular oxidative stress and dysfunction: evidence for a close connection to brain damage and a key ro…
2019
Abstract Aims Electronic (e)-cigarettes have been marketed as a ‘healthy’ alternative to traditional combustible cigarettes and as an effective method of smoking cessation. There are, however, a paucity of data to support these claims. In fact, e-cigarettes are implicated in endothelial dysfunction and oxidative stress in the vasculature and the lungs. The mechanisms underlying these side effects remain unclear. Here, we investigated the effects of e-cigarette vapour on vascular function in smokers and experimental animals to determine the underlying mechanisms. Methods and results Acute e-cigarette smoking produced a marked impairment of endothelial function in chronic smokers determined b…
Biblioteca de la Casa de Osuna en la Universidad de Granada
2023
Se pretende dar luz al fondo existente en la Biblioteca de la Universidad de Granada de los libros ingresados de la Casa de Osuna. Existía una parte identificada, pero al no disponer de un listado como otras Universidades, se han tenido que identificar las distintas marcas de procedencia uno a uno, trabajo lento y laborioso. También hemos recogido otras marcas de procedencia de otros poseedores de la Casa de Osuna, con supralibros, dedicatorias, o exlibris impresos y manuscritos.
A Comparative Overview of the Canadian Senate and the British House of Lords
2018
The purpose of this overview is to highlight the role which is played by the Canadian Senate and the British House of Lords in their constitutional legal systems, and to attempt to underline what similarities or differences can be identified in relation to their composition and functions. This paper will analyse whether they have an actual representative capacity and if they are able to perform the typical functions which are normally allocated to the upper chambers, functioning as a “sober second thought” and a house of check on the majority expressed in the lower chamber, usually connected to the Cabinet. The contribution of these chambers to parliamentary systems of government will also …
La literatura en la frontera lingüística : el caso de la escritora italo-suiza Fleur Jaeggy
2012
"El verdadero milagro proustiano no es que una magdalena mojada en té tenga el mismo gusto que otra magdalena mojada en té y despierte el recuerdo; es, más bien, que esa segunda magdalena resucite con ella un cuarto, una casa, una ciudad entera, y que ese lugar antiguo pueda, por espacio de un segundo, conmover la solidez del lugar actual, forzar sus puertas y hacer vacilar sus muebles." [1] Genette aporta con estas palabras la idea principal de lo que en esta tesis se pretende analizar, es decir, llegar a la dimensión evocadora del contenido de los textos, del lenguaje, de los universos, de los motivos literarios, en este caso concreto a la dimensión evocadora de una autora que considero p…
Physiology of Zymomonas mobilis: Some Unanswered Questions
2006
The ethanol-producing bacterium Zymomonas mobilis can serve as a model organism for the study of rapid catabolism and inefficient energy conversion in bacteria. Some basic aspects of its physiology still remain poorly understood. Here, the energy-spilling pathways during uncoupled growth, the structure and function of electron transport chain, and the possible reasons for the inefficient oxidative phosphorylation are analysed. Also, the interaction between ethanol synthesis and respiration is considered. The search for mechanisms of futile transmembrane proton cycling, as well as identification of respiratory electron transport complexes, like the energy-coupling NAD(P)H:quinone oxidoreduct…
