Differential regulation of hexameric and dodecameric hemocyanin from A. leptodactylus
2013
The oxygen binding properties of hemocyanins are regulated on a short time scale by effectors such as l-lactate, urate and protons, and on longer time scales by expression of the different types of subunits. For Astacus leptodactylus it was shown previously that acclimation to higher temperatures leads to increased levels of a 6-meric hemocyanin species, whereas at lower temperatures the 12-meric form prevails. Here we show that the temperature dependence of the two forms supports the idea, that the maintenance of high affinity towards oxygen is the driving force for the differential expression of these hemocyanins. Furthermore, the two different types of hemocyanin differ not only in the a…
Effects of 24 h Compression Interventions with Different Garments on Recovery Markers during Running
2021
Compression and temperature manipulation are discussed as strategies to improve performance markers and recovery in sports. Here, we investigate the effects of compression stockings made with fabric, either combined or not with heating and cooling substances, on variables related to running performance and recovery. Ten trained runners (mean ± standard deviation age 45 ± 9 years old, body mass 69 ± 7 kg, height 166 ± 4 cm) with no experience of using compression garments performed an intense running session of 10 km, then wore a stocking for 24 h (randomized

Biotic oxidation of methane in landfills in boreal climatic conditions
2010
This study focused on the biotic oxidation of methane in landfill covers as a technology for reducing greenhouse gas emissions from landfills, particularly those located in the boreal climatic zone. First, methane oxidation was studied in laboratory batch assays in a landfill cover soil consisting of a composted mixture of sewage sludge and chemical sludge which had been installed on the landfill surface 4-5 years earlier. Second, methane oxidation was studied using mechanically-biologically treated municipal solid waste (MBT residual) as a material for methane-oxidizing landfill covers both in continuously methane-sparged laboratory columns and in an outdoor pilot lysimeter. Finally, meth…
Research data of an article: "Application of high resolution melting assay (HMR) to study temperature dependent infraspecific competition in an patho…
2017
Studies on species’ responses to climate change have focused largely on the direct effect of abiotic factors and in particular temperature, neglecting the effects of biotic interactions in determining the outcome of climate change projections. Many microbes rely on strong interference competition; hence the fitness of many pathogenic bacteria could be a function of both their growth properties and intraspecific competition. However, due to technical challenges in distinguishing and tracking individual strains, experimental evidence on intraspecific competition has been limited so far. Here, we developed a robust application of the high-resolution melting (HRM) assay to study head-to-head co…
Comparación de las temperaturas de brillo en Banda L proporcionadas por SMOS y Aquarius sobre distintas zonas de la Tierra
2017
En esta Tesis Doctoral se analizan datos procedentes de dos misiones espaciales de observación de la Tierra que han coincidido en el tiempo, SMOS (Soil Moisture Ocean Salinity), de la European Space Agency (ESA) y Aquarius, de la National Aeronautics and Space Administration (NASA). Estas misiones miden la temperatura de brillo de la Tierra en la banda L de microondas, entre otras variables geofísicas. Este trabajo se centra, fundamentalmente, en la comparación de este parámetro proporcionado por ambas misiones. Las diferentes resoluciones espaciales que proporcionan los sensores de ambos satélites hace difícil la comparación y esto ha motivado la aplicación de diferentes técnicas o métodos…
Biogeographic patterns of base-rich fen vegetation across Europe
2014
International audience; Questions: What is the distribution of base-rich fen vegetation and the specia- list species along European biogeographic regions? How do the gradients in spe- cies composition correlate to geography and climate at continental scale? What are the implications of such patterns for the classification of these habitats?Location: Fifteen countries of Central, Western and Northern Europe.Methods: We compiled a vegetation plot database of base-rich fens and related communities including vascular plants and bryophytes. The initial data set with 6943 plots was filtered according to the presence of specialists using discriminant analysis. We used DCA to analyse the correlatio…
Molecular nanostructures on ferromagnetic metals for spintronics
2017
El objetivo principal de esta tesis ha sido el estudio de la funcionalización de superficies ferromagnéticas mediante la formación de monocapas moleculares autoensambladas, (SAMs, self-assembled monolayers) con el fin de conseguir procesos sencillos y fiables para la preparación de interfaces híbridas aplicables en dispositivos de espintrónica molecular. La investigación se ha centrado en la funcionalización de materiales ferromagnéticos, concretamente el cobalto y la aleación de níquel:hierro conocida como Permalloy. Las propiedades magnéticas y de polarización de espín de estos metales ferromagnéticos se mantienen a temperatura ambiente, lo que los hace muy interesantes para su aplicación…
Estudio y evaluación de la estabilidad del alcohol etílico en muestras de sangre almacenadas en condiciones de temperatura de congelación
2015
La determinación del alcohol etílico es una de las analíticas más solicitadas en la toxicología forense y su implicación médico legal es de gran importancia. El alcohol etílico es una sustancia volátil y su estabilidad está influenciada por una serie de factores y/o variables, como son condiciones preanalíticas no adecuadas, difusión y redistribución postmortem y generación o pérdidas de alcohol etílico. En base a estos hechos, se ha planteado la presente Tesis ya que las condiciones de almacenamiento de las muestras de sangre constituyen un factor importante en la estabilidad del alcohol etílico y, por consiguiente, puede influir a la hora de informar un resultado fiable y válido cuando se…
A person-oriented approach to diary data. Children’s temperamental negative emotionality increases susceptibility to emotion transmission in father-c…
2015
The notion that some individuals are more prone to emotion transmission than others has prompted the need for a person-oriented approach to emotion transmission in parent-child dyads. The present study applied a person-oriented analysis to examine the patterns of emotion transmission that can be identified in the diary data of father-child dyads, and the extent to which children with high levels of temperamental negative emotionality are particularly susceptible to emotion transmission within the family. Mothers of 149 first grade children (age 6 to 7) completed questionnaires concerning their child’s temperament. Mothers and fathers maintained diary questionnaires (for a total of 7 days) c…
