Metagenomics Reveals Planktonic Bacterial Community Shifts across a Natural CO2 Gradient in the Mediterranean Sea
2015
ABSTRACT Bacterial communities at a CO 2 vent (pH 6.7) were compared with those at control (pH 8.0) and transition sites (pH 7.6) using 16S rRNA metagenomics. Firmicutes and unclassified bacteria dominated across all sites, Proteobacteria , especially Gammaproteobacteria , declined, and Epsilonproteobacteria increased in the vent with an increase in Bacteroidetes at both the vent and transition sites.
The Role of Geographic Technologies in the Measure of Spatial Equity. Twenty-First Century Solutions for Old Geographical Issues
2019
In Western societies, the development of the Welfare State has been accompanied by the proposal of different models of spatial organisation that help to improve spatial equity, this being a priority object of all public policy because it clearly contributes to the achievement of a greater social cohesion. Geography has contributed, from Christaller to the present, to propose territorial models that help to optimise the location of activities and services, using spatial statistics and digital cartography. At present, the study of spatial equity is again receiving the attention of the academy, in particular as regards the provision of public services and facilities in urban and metropolitan a…
Introducción de nuevos equipos e implementación de técnicas especiales aplicadas al tratamiento de lesiones de piel en radioterapia
2017
En el presente trabajo se ha realizado un análisis de riesgo de dos modalidades de tratamiento radioterápico de piel, la braquiterapia electrónica (eBT) y la irradiación total de la piel con electrones (TSEI). Paralelamente, se ha hecho un estudio de blindajes para la unidad de tratamiento de eBT. El trabajo se ha dividido en 4 capítulos. El capítulo 1 resume las principales ventajas de las técnicas de tratamiento del cáncer de piel no melanoma que se utilizan actualmente en radioterapia, contextualizando la implantación de la eBT. También se expone el tratamiento de la micosis fungoide en radioterapia, enfermedad que afecta a toda la superficie corporal del paciente, para la cual, la TSEI …
Phenology Estimation From Meteosat Second Generation Data
2013
Many studies have focused on land surface phenology, for example as a means to characterize both water and carbon cycles for climate model inputs. However, the Spinning Enhanced Visible Infra-Red Imager (SEVIRI) sensor onboard Meteosat Second Generation (MSG) geostationary satellite has never been used for this goal. Here, five years of MSG-SEVIRI data have been processed to retrieve Normalized Difference Vegetation Index (NDVI) daily time series. Due to existing gaps as well as atmospheric and cloud contamination in the time series, an algorithm based on the iterative Interpolation for Data Reconstruction (IDR) has been developed and applied to SEVIRI NDVI time series, from which phenologi…
Mixotrophy in Pyroleae (Ericaceae) from Estonian boreal forests does not vary with light or tissue age
2017
SPE IPM UB; International audience; In temperate forests, some green plants, namely pyroloids (Pyroleae, Ericaceae) and some orchids, independently evolved a mode of nutrition mixing photosynthates and carbon gained from their mycorrhizal fungi (mixotrophy). Fungal carbon is more enriched in 13C than photosynthates, allowing estimation of the proportion of carbon acquired heterotrophically from fungi in plant biomass. Based on 13C enrichment, mixotrophic orchids have previously been shown to increase shoot autotrophy level over the growth season and with environmental light availability. But little is known about the plasticity of use of photosynthetic versus fungal carbon in pyroloids. Met…
On the power and the systematic biases of the detection of chromosomal inversions by paired-end genome sequencing
2013
One of the most used techniques to study structural variation at a genome level is paired-end mapping (PEM). PEM has the advantage of being able to detect balanced events, such as inversions and translocations. However, inversions are still quite difficult to predict reliably, especially from high-throughput sequencing data. We simulated realistic PEM experiments with different combinations of read and library fragment lengths, including sequencing errors and meaningful base-qualities, to quantify and track down the origin of false positives and negatives along sequencing, mapping, and downstream analysis. We show that PEM is very appropriate to detect a wide range of inversions, even with …
Recent trends in solar exergy and net radiation at global scale
2012
Abstract The availability during the last decades of remotely sensed images and global climatic data allow us to analyse the “Earth system” as a whole in order to develop concepts for global environmental management. This system can be considered a complex, dissipative, dynamic entity, far from thermodynamic equilibrium ( Schellnhuber, 1999 ). Energy balance has been considered for many decades to understand the functioning of ecosystems, the biosphere or the Earth planet as a whole, but it is also possible to study our planet from a thermodynamic point of view. In this letter we analyse recent trends in solar exergy and net radiation at global scale during the period 1980–2010, distinguish…
FISH: Face Intensity-Shape Histogram representation for automatic face splicing detection
2019
Abstract Tampered images spread nowadays over any visual media influencing our judgement in many aspects of our life. This is particularly critical for face splicing manipulations, where recognizable identities are put out of context. To contrast these activities on a large scale, automatic detectors are required. In this paper, we present a novel method for automatic face splicing detection, based on computer vision, that exploits inconsistencies in the lighting environment estimated from different faces in the scene. Differently from previous approaches, we do not rely on an ideal mathematical model of the lighting environment. Instead, our solution, built upon the concept of histogram-ba…
Smart Tools for Academic Information Seeking
2016
Systematic information seeking is an essential part of academic work. Research and information seeking go hand in hand, and both need planning. In the academic world you can hardly avoid the research plan, but you probably won’t hear that much about the information seeking plan. The information seeking plan guides you through the research process from the first sparks of an idea to the last dot in the bibliography from the point of view of the often invisible process of systematic information seeking.Systematic Information Seeking Framework designed in the Jyväskylä University Library has its roots in Carol Kuhlthau's Guided Inquiry Design Process. Our model, designed for more contextual ad…
