This article addresses the concept of disability by covering the multiple dimensions and coordinates that intersect the phenomenon from a perspective that makes it possible to describe, analyse and understand the complexity of what is entwined in the term disability. It aims to present a theoretical-conceptual distinction with heuristic, analytical and explanatory capacity based on the triad of condition, situation and position of disability. To this end, a study was carried out in order to deploy relevant conceptual mediations that provide solidity and density to each notion and its articulations. From the results, the condition of disability is related to the material and symbolic state of the very personal and non-transferable experience in the biographical trajectories and the imprints of subjectivation. The situation of disability refers to the processes of disablement that emerge from face-to-face interactions in everyday life, from intersubjective experiences, from co-presence and co-inhabiting. Finally, the position of disability refers to the aspects and structural dynamics of long time that demarcate this position in the social field, in relation to the other historically constituted positions. The final reflections help to appreciate a reality in which the coordinates of the triad —like light, which is sometimes a wave and sometimes a particle— sometimes function as dimensions, sometimes as levels and sometimes as communicating vessels.

Parachondria neglectus is a terrestrial mollusk endemic of Cuba. This species constitutes the only report of the Annulariidae family in the municipality of Manzanillo, Granma province. In the present study, the temporal dynamics of the structural subniche of a population of P. neglectus was characterized. Thirty expeditions were carried out between December 2013 and February 2015. 83.9 % of the mollusks were found on the ground (around the base of trees and shrubs) and 16.1 % used the trunk of eight plant species as diurnal resting substrate. The test of independence performed using a 2×2 contingency table with Yates correction showed that in the population the frequency of using one substrate or another depends on the occurrence or not of rainfall (X2 = 214.88; P = 0.0001). This species was found at an average trunk distance of 13 ± 6.42 cm. The C-index values indicated marked preference of this mollusk for Swietenia mahagoni during all climatic periods sampled. During the rainy season this species also showed statistically significant preferences for Cordia gerascanthus, Ehretia tinifolia and Bursera simaruba. For the population, the height above the ground presented a mean value of 153.5 ± 71.3 cm. The heights above the ground reached by this species on rainy and non-rainy days showed statistically significant differences (U = 21519.5; P < 0.001). [ABSTRACT FROM AUTHOR]

The COOPMERCASAN peasant market began its operation in 2011, providing fresh and safe agricultural products to the population of Florence. In these eight years of operation, they have had successes and failures, they have also received the support of different institutions, however, to date, their current realities are unknown, as well as the challenges, which have been changing over time. It is because of the above that this research sought to build the dynamics of this experience through self-reflection, base information for decision-making, and the orientation of their improvement actions. The work was carried out in the municipality of Florence, the tools for gathering the information were surveys, interviews, and participant observation. Among the main findings, it was discovered that, although the market has managed to position itself with an interesting customer base, its offer is not meeting expectations in terms of the volumes and diversity demanded by customers and that, although the vast majority of the support provided by the institutions has been directed towards organizational strengthening processes, it continues to be the weakest aspect.

The interconnection of the Central Interconnected System (SIC for its initials in Spanish) with the Northern Interconnected System (SING) have been one of the trending topics in the year 2013 in the Chilean electric industry. Two are the projects that are on target for the interconnection; a high voltage alternating current (HVAC) 500 kV connection, proposed by the French utility GDF SUEZ, and a high voltage direct current (HVDC) ±500 kV planned by the CNE, the Chilean electric regulator entity. Both projects have important differences in technology and there's not too much technical evidence of the problems that could arise in the operation, caused by the SIC-SING interconnection. Low frequency oscillations are studied in this work, using modal analysis for both interconnection projects. A SIC-SING model is developed using DigSilent software, considering 2019 as the year of a possible union of the networks. Two generation scenarios are studied; one where the central system (SIC) sends 1.000 MW to the northern system (SING), and another one where the SING sends 800 MW to the SIC. The modal analysis results show that interconnecting both systems with the HVAC gives arise to a 0.5 Hz unstable oscillation mode. This unstable mode has it origin on the interconnection and it's related to a group of steam machines on the SING system. Whether the SIC-SING system is connected with the HVAC or the HVDC, 0.9 Hz weakly damped modes are observed in both systems. These modes are related to the evolution of the systems at 2019.

The investigation of the structural properties and the photoinduced relaxation dynamics of noble gas matrices and clusters has experienced an accelerated progress during the last two decades. The marked sensibility of the electronic states of the impurity to the modifications in the environment enables the accurate characterization of the time-evolution of the dynamical processes in condensed phase. Noble gas systems at low temperature, apart from their great advantages for molecular spectroscopy studies, exhibit unique properties from the fundamental point of view, derived from the significant influence of quantum delocalization effects on the dynamics of the system. In this review, an overview is presented of some of the experimental and theoretical tools used nowadays, in the study of the geometrical rearrangement and the mechanisms of energy transfer into the medium, as well as several illustrative examples that have contributed, in recent years, to shape our understanding of these phenomena.

Prior to the development of infrastructure, space had a continuous character, given that the time it took to access a given place increased gradually with the distance to that place. Motorways and state highways have produced a contraction of space as far as road transport is concerned, due to the decrease in distance as measured in terms of time. However, this contraction has not been uniform across space. The main beneficiaries of the new spatial order are the nodes that link together trunk roads - which usually coincide with urban agglomerations -, insofar as they are connected to each other in quick and efficient ways. This gives rise to a new way of looking at the imbalances between the centre and the periphery - that is to say, between the main urban agglomerations and their regional hinterlands, as structured in an increasingly discontinuous space. As a consequence, the construction of new transport infrastructures (which are essential to socioeconomic development and to the articulation and integration of the various spaces and localities) can modify the population's spatial dynamics and accessibility levels, with crucial consequences in terms of regional development. With this in mind, this study proposes to analyse the current relationship between the development of transport infrastructures and accessibility in the case of the main urban agglomerations in the Iberian Peninsula.

The determination of the state of a structure represents an important factor in the use of structural systems. This is known as structural health monitoring (SHM). Several methods, the most of them visuals, are employed. These require a direct access to the possible damaged zone an can be very time consuming and costly, a reason by which the researchers in this field are focused in others method, like modal analysis. The wavelet transform is also a very powerful toll in crack detection in early stages. This problem should be studied in a practical and theoretical way. In this paper a transverse closed crack is represented in an Euler-Bernoulli beam, as Bovsunovsky. Continuous and finite element models are used, and the wavelet transform is applied to the eigenmodes. [ABSTRACT FROM AUTHOR]
