Glycine-functionalized copper(ii) hydroxide nanoparticles with high intrinsic superoxide dismutase activity
2017
Superoxide dismutases (SOD) are a group of enzymes that catalyze the dismutation of superoxide (O2−) radicals into molecular oxygen (O2) and H2O2 as a first line of defense against oxidative stress. Here, we show that glycine-functionalized copper(II) hydroxide nanoparticles (Gly-Cu(OH)2 NPs) are functional SOD mimics, whereas bulk Cu(OH)2 is insoluble in water and catalytically inactive. In contrast, Gly-Cu(OH)2 NPs form water-dispersible mesocrystals with a SOD-like activity that is larger than that of their natural CuZn enzyme counterpart. Based on this finding, we devised an application where Gly-Cu(OH)2 NPs were incorporated into cigarette filters. Cigarette smoke contains high concent…
Timing and patterns of the ENSO signal in Africa over the last 30 years: insights from normalized difference vegetation index data.
2014
Abstract A more complete picture of the timing and patterns of the ENSO signal during the seasonal cycle for the whole of Africa over the three last decades is provided using the normalized difference vegetation index (NDVI). Indeed, NDVI has a higher spatial resolution and is more frequently updated than in situ climate databases, and highlights the impact of ENSO on vegetation dynamics as a combined result of ENSO on rainfall, solar radiation, and temperature. The month-by-month NDVI–Niño-3.4 correlation patterns evolve as follows. From July to September, negative correlations are observed over the Sahel, the Gulf of Guinea coast, and regions from the northern Democratic Republic of Congo…
Estudi comparatiu de l’atenuació pragmàtica en la llengua catalana: converses col·loquials prototípiques-converses col·loquials perifèriques
2017
A comparative study on pragmatic mitigation in a corpus of colloquial conversations in Catalan has been conducted in this work. Its aim objective is to study mitigation in a contrastive way, that is to say, to examine the usage contrast of this pragmatic strategy amongst prototypical colloquial conversations and peripheral colloquial conversations. For this purpose, it was believed appropriate to previously explain conversational genre and colloquial register, that is to say, colloquial conversation and its characteristics. In order to conduct thus study, one’s own corpus has been complied (recorded and transcribed) consisting of five colloquial conversations: two prototypical ones and thre…
Turning the tide: Registered nurses' job withdrawal intentions in a Finnish university hospital
2012
Orientation: Given the global shortage of registered nurses, it is important to investigate the intentions for job withdrawal of nurses, and resolve these, in order to retain nurses in the field. Research purpose: The objective was to examine the intentions for job withdrawal of ageing and younger nurses, and the antecedents of these intentions, with special reference to job control and perceived development opportunities. The age of 45 was adopted as a starting point when referring to ageing employees. Motivation for the study: Different forms of job withdrawal have rarely been studied together and associated. Research design, approach and method: A quantitative study was applied with logi…

Como as práticas ecológicas e o desperdício de alimentos influenciam o capital de marca do restaurante?
2020
Resumen El presente trabajo tuvo por objetivo evaluar la incidencia de las prácticas verdes, la innovación sostenible y el manejo del desperdicio alimentario en la construcción del capital de marca de los restaurantes. A partir de una investigación cuantitativa dirigida a responsables de restaurantes en Ecuador, se obtuvieron 120 cuestionarios válidos que permitieron estimar un modelo de ecuaciones estructurales a través de la regresión de mínimos cuadrados parciales. Los resultados obtenidos evidencian que las prácticas verdes orientadas a la formación del empleado y la innovación sostenible contribuyen significativamente a la reducción del desperdicio alimentario, que, a su vez, junto a l…

Excepcionalidad y resistencia anti-hispánica en los Países Bajos: estrategias de legitimación de la Revuelta en panfletos y literatura neerlandesa (1…
2020
Resumen: Las Guerras de Flandes, la Guerra de Ochenta Años o la Revuelta de/en los Países Bajos es el episodio histórico que más estrechamente vincula a España y los Países Bajos. Para los neerlandeses, este conflicto bélico constituye el mito funcional de lo que llegaría aser la República de las Provincias Unidas y posteriormente (el reino de) los Países Bajos. Larevuelta ante su señor natural Felipe II se presenta desde perspectiva neerlandesa ya des delos anales del conflicto como un ejemplo de resistencia justificada y legitimable, no sólo antepotencias extranjeras, sino también dentro del seno de la propia sociedad. Esta contribuciónse concentra en algunas de las refinadas estrategias …
