Neuroeducación en virtudes cordiales. Una propuesta a partir de la neuroeducación y la ética discursiva cordial
2014
El tema de la tesis es proponer una educación en virtudes cordiales, fundamentadas en la obra de Adela Cortina, y llevar a cabo esa educación mediante un diseño educativo y pedagógico acorde con los últimos avances en neuroeducación. OBJETIVOS: El objetivo principal es demostrar la necesidad de educar en virtudes cordiales, que por ser procedimentales e ir dirigidas a regular una convivencia pacífica y buscar la justicia global, son universalizables y por tanto, asumibles por cualquier sujeto, sea cual sea su cultura de origen. Además, me propongo demostrar que un programa neuroeducativo es el tipo de educación idónea para este propósito. Para alcanzar este objetivo principal, me propongo v…
Molecular Characterization of a Variant of Bacillus anthracis-Specific Phage AP50 with Improved Bacteriolytic Activity▿ †
2008
ABSTRACT The genome sequence of a Bacillus anthracis -specific clear plaque mutant phage, AP50c, contains 31 open reading frames spanning 14,398 bp, has two mutations compared to wild-type AP50t, and has a colinear genome architecture highly similar to that of gram-positive Tectiviridae phages. Spontaneous AP50c-resistant B. anthracis mutants exhibit a mucoid colony phenotype.
Quantitative microscopy reveals stepwise alteration of chromatin structure during herpesvirus infection
2019
During lytic herpes simplex virus 1 (HSV-1) infection, the expansion of the viral replication compartments leads to an enrichment of the host chromatin in the peripheral nucleoplasm. We have shown previously that HSV-1 infection induces the formation of channels through the compacted peripheral chromatin. Here, we used three-dimensional confocal and expansion microscopy, soft X-ray tomography, electron microscopy, and random walk simulations to analyze the kinetics of host chromatin redistribution and capsid localization relative to their egress site at the nuclear envelope. Our data demonstrated a gradual increase in chromatin marginalization, and the kinetics of chromatin smoothening arou…
Conception en technologie CMOS d'un Système de Vision dédié à l'Imagerie Rapide et aux Traitements d'Images
2008
Our work presented in this thesis focuses on the design, testing and implementation of monolithics CMOS image smart sensors : The principle, performance and limitations. The hardware implementation of a vision smart system is the central link. HISIC is High Speed Image Capture with processing at pixel level. An experimental platform for instrumentation and evaluation of retina operators was conducted during this thesis. After a state of the smart sensors and CMOS retinas, the second part is dedicated to the study and design of the pixel image sensor HISIC. Two circuits were realized in CMOS technology. The first identied a new type of photo-detector, and the second, to create a prototype em…
Toimijuus korkeakoulutettujen suomen oppijoiden visuaalisissa narratiiveissa
2018
This socioculturally informed study explores how highly educated Finnish language learners represent their agency in visual narratives. Learners (n=59) were asked to draw two pictures of themselves as Finnish language users and provide verbal interpretations of the drawings. The aim of using visual narratives is to reach aspects such as feelings and beliefs which might be difficult to express verbally. The data were analyzed first by using visual grammar set out by Kress and van Leeuwen (2006) and secondly by content analysis. The findings suggest that learners saw Finnish language as a tool for oral communication. However, difficulties with speaking and listening appeared to restrict learn…
Shooting borders. Per una geogafia visuale delle migrazioni
2017
Our perceptions of events in the Mediterranean are strongly influenced by a range of visual practices that impact on both the emotional and the political. In this paper, I set out to critically explore the visual geographies underlying photographic images of contemporary migration flows across the Mediterranean Sea. I argue the need for a methodological shift from a content analysis approach to a critical investigation of the spatial interweaving of images, gazes and aesthetic regimes that governs both the production and reception of such photographs. Given these theoretical premises, I focus on three images of migrants being rescued in the Mediterranean to illustrate how photography can ac…
Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates
2021
We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…
Endophytic Fungi in Asymptomatic Vitis vinifera L. and their Effects on Plasmopara viticola
2016
During a multi-year study on the life cycle of Plasmopara viticola to assess the typical epidemiology of downy mildew on grapevine (Vitis vinifera) in west Sicily (Italy), several leaves on which the downy mildew had collapsed were found and observed in a vineyard located in Marsala, in Trapani Province. An antagonistic fungus was isolated from these leaves and named A20; through its morphology, it was identified as a hyphomycete belonging to the genus Acremonium. The antagonism of A20 against the asexual and sexual spores of P. viticola, as well as endophytic nature of the genus Acremonium in V. vinifera were confirmed by further studies which have been carried out over the past decade. In…
Highly sensitive olfactory biosensors for the detection of volatile organic compounds by surface plasmon resonance imaging
2018
International audience; Nowadays, monitoring of volatile organic compounds (VOCs) is very important in various domains. In this work, we aimed to develop sensitive olfactory biosensors using odorant binding proteins (OBPs) as sensing materials. Three rat OBP3 derivatives with customized binding properties were designed and immobilized on the same chip for the detection of VOCs in solution by surface plasmon resonance imaging (SPRi). We demonstrated that the proteins kept their binding properties after the immobilization under optimized conditions. The obtained olfactory biosensors exhibited very low limits of detection in both concentration (200pM of beta-ionone) and in molecular weight of …
Gas Emissions From the Western Aleutians Volcanic Arc
2021
The Aleutian Arc is remote and highly active volcanically. Its 4,000 km extent from mainland Alaska to Russia’s Kamchatka peninsula hosts over 140 volcanic centers of which about 50 have erupted in historic times. We present data of volcanic gas samples and gas emission measurements obtained during an expedition to the western-most segment of the arc in September 2015 in order to extend the sparse knowledge on volatile emissions from this remote but volcanically active region. Some of the volcanoes investigated here have not been sampled for gases before this writing. Our data show that all volcanoes host high-temperature magmatic-hydrothermal systems and have gas discharges typical of volc…
