Pincio y los Estados Unidos que no son los Estados Unidos
2015
Lo neofantástico en Tommaso Pincio se distingue de lo fantástico posmoderno de nuestros escritores. Se basa en la realidad estadounidense contemporánea; la introduce en un proceso de elaboraciones enfáticas, mezclas, transfiguraciones, y la convierte en el símbolo de otro mundo, de un planeta extraño. Pincio llega a esta operación creativa gracias a su conocimiento de las tradiciones y de las costumbres, de la historia, de la cultura y de la literatura de los Estados Unidos. De todo eso quiere darse una idea en este ensayo, analizando la segunda novela de Pincio, Spazio sfinito, en la que se representa a unos Estados Unidos que no son Estados Unidos.
Pole-to-Pole Connections: Similarities between Arctic and Antarctic Microbiomes and Their Vulnerability to Environmental Change
2017
The global biogeography of microorganisms remains poorly resolved, which limits the current understanding of microbial resilience toward environmental changes. Using high-throughput 16S rRNA gene amplicon sequencing, we characterized the microbial diversity of terrestrial and lacustrine biofilms from the Arctic, Antarctic and temperate regions. Our analyses suggest that bacterial community compositions at the poles are more similar to each other than they are to geographically closer temperate habitats, with 32% of all operational taxonomic units (OTUs) co-occurring in both polar regions. While specific microbial taxa were confined to distinct regions, representing potentially endemic popul…
Análisis de la elección de la pierna de ataque predominante en la prueba de 400 m vallas de los XIII Campeonatos del Mundo de Atletismo Daegu 2011
2012
Objetivos: Analizar la utilización de una u otra pierna como pierna de ataque predominante en atletas de 400 m vallas de alto nivel. Método: El estudio es descriptivo de corte transversal. Se estudiaron todas las carreras de 400 m vallas de los 72 participantes (34 hombres y 38 mujeres) en los XIII Campeonatos del Mundo de Atletismo Daegu 2011, mediante la grabación en video desde la tribuna principal del Daegu Stadium de las 18 carreras de 400 m vallas disputadas, y el posterior análisis mediante la aplicación informática Kinovea 0.8.4. Resultados: Por atletas, en el total de las carreras masculinas, la pierna de ataque predominante fue la izquierda con un 63,6 % (42 atletas) y con la pier…
Plantar pressure and foot temperature responses to acute barefoot and shod running
2015
AbstractPurpose. Increased contact pressure and skin friction may lead to higher skin temperature. Here, we hypothesized a relationship between plantar pressure and foot temperature. To elicit different conditions of stress to the foot, participants performed running trials of barefoot and shod running. Methods. Eighteen male recreational runners ran shod and barefoot at a self-selected speed for 15 min over different days. Before and immediately after running, plantar pressure during standing (via a pressure mapping system) and skin temperature (using thermography) were recorded. Results. No significant changes were found in plantar pressure after barefoot or shod conditions (p > 0.9). …
Natural assets in the right-of-way of A-4 Motorway in the Góra Świętej Anny Landscape Park, Opole Region
2014
Construction of the A-4 Motorway section in the Opole Region begun in Summer 1997. Very soon vigorous resistance of ecological NGOs was encountered. The bone of contention was the section of motorway that passes through the Góra Świętej Anny Landscape Park and verges the natural reserve of strict protection Ligota Dolna where rare species of thermophilic plants are sheltered. Between 2011 and 2013 a detailed mycological, geobotanical, floristic and fauna research took place within the right-of-way of the A-4 Motorway section crossing the Góra Świętej Anny Landscape Park in the Opole Region. The survey revealed several rare and protected species of fungi, plants and animals along the road, i…
Softening of Silica Filled Styrene-Butadiene Rubber under Uniaxial Cyclic Loading
2016
Stress-strain behaviour of silica filled styrene-butadiene rubber showed strong hysteresis and cyclic softening, while these effects were almost negligible for the neat rubber. Significant Mullins effect occurs between the first and second loading cycles, whereupon samples reach their steady state after four repeated cycles. The degree of softening increases with volume content of silica characterizing the softening effect as a breakdown of the filler-formed microstructure defined by both, specific interactions in the filler associations and between the filler and rubber matrix. Contribution of different damage mechanisms to the total energy losses on different stages of extension was estim…
Volume Changes in Filled Rubber Under Uniaxial Cyclic Loading
2011
Styrene-butadiene rubber, neat and filled with different silica content was investigated under uniaxial cyclic loading under a constant crosshead speed, with increasing deformation amplitude in subsequent loading cycles. Rubber was investigated in order to evaluate the reversibility of structure rearrangements, occurring in rubber when subjected to cyclic loading. Volume uniformly increases with growing strain and shows hysteresis at unloading. After complete unloading, no residual strain changes are observed. These data are in good conformity with the data of density measurements, which were made on specimens before and after the tests. By correlating data, obtained from volume changes and…
A Comparative Analysis of Performance Management Systems
2012
Performance management is maturing as an effective organizational approach in public organizations around the world, but the existing models have limitations that must be addressed. The international comparative case study analysis in this article presents policy recommendations and organizational strategies on how regional governments can create more robust performance management systems for higher levels of accountability and transparency in a time of global economic crisis. These include the consideration of organizational structure regarding alignment, control, and culture, the positive impact of performance management legislation, the role of executive leadership, and the need for an i…
Regional leadership: a systemic view
2012
Published version of an article in the journal: Systemic Practice and Action Research. Also available from the publisher at: http://dx.doi.org/10.1007/s11213-012-9268-2 New innovation and industrial policies contribute to the development of an informal economy and have increased collaborative processes across sectors and social spheres within regions. This paper addresses the role of regional leadership in the informal economy. By themselves, network processes increase complexity and create a series of uncertainties that differ from processes that are steered through the hierarchical procedures of public bureaucracy or regulated through the judicial and competitive mechanisms of the market.…
RNA-Binding Proteins as Epigenetic Regulators of Brain Functions and Their Involvement in Neurodegeneration.
2022
A central aspect of nervous system development and function is the post-transcriptional regulation of mRNA fate, which implies time- and site-dependent translation, in response to cues originating from cell-to-cell crosstalk. Such events are fundamental for the establishment of brain cell asymmetry, as well as of long-lasting modifications of synapses (long-term potentiation: LTP), responsible for learning, memory, and higher cognitive functions. Post-transcriptional regulation is in turn dependent on RNA-binding proteins that, by recognizing and binding brief RNA sequences, base modifications, or secondary/tertiary structures, are able to control maturation, localization, stability, and tr…
