Histórias de adoção tardia: considerações a partir da analítica existencial heideggeriana

Adoption establishes a filiation status, resulting from a legal act, which attributes to the child and parents the rights and obligations associated with such condition, being legally irrevocable. Nevertheless, in practice there are adoptions that do not concretize and the child returns to justice during or even after the legal process is closed. Late adoption is the denomination of the adoption of children over two years and it is still permeated by myths and stigmas, leading to a frequent return of the child to justice in these cases. The late adoption involves a process of building a unique relationship with a child whose backstory is commonly marked by the dissolution of the relationship with the family of origin, due to violation of rights and, in some cases, the experience of institutional care. Given such a scenario, this research, based on the Existential Analytic proposed by Martin Heidegger, seeks to understand the experience of mothers and children in the process of late adoption, in order to obtain subsidies to psychological attention in this context. This is a qualitative, phenomenological study with a comprehensive focus. The participants were two mothers and two children who have gone through late adoption for about two years. The procedures of data generation contemplated narrative interviews with mothers and individual meetings with children, in which ludic resources were used as mediators of expression (free drawings, unfinished children's story and "Story-Drawings" on late adoption). The procedures were audiotaped and transcribed. Data analysis was grounded in Heidegger's hermeneutics. The late adoption process, permeated by historical, social and cultural determinants and the web of meanings that create the historical singularity of each person involved have proved to be complex as seen in the narratives. The construction of the meanings of parenthood and filiation has been developing in the families in the study, from the experience of being-with-the-other, caring and dwelling in their peculiar modes of expression. The family of origin and the adoptive family mingle and differentiate by means of the experience of children, especially because of the existence of biological siblings. Data point to the importance of psychological care to family core in late adoption processes

Sensibilidade à mudança de trajetória de deformação no aço TWIP980

Resultante dos avanços tecnológicos, conseguiu-se obter um aço que elimina o paradigma de se aliar alta ductilidade e resistência mecânica. Assim foi desenvolvido durante a última década o aço TWIP, deformação induzida por maclação, tendo como principal mecanismo de deformação a maclação. Este presente trabalho teve como principal objetivo caraterizar o aço TWIP980 em três temáticas diferentes: química, mecânica e microestrutura. Na primeira temática, a química, esta teve como objetivo encontrar a designação do aço TWIP em estudo. Sendo apenas conhecida a direção de laminação, RD, e a empresa que forneceu as chapas, a POSCO, o objetivo era obter a sua designação. Através da comparação das curvas de tração encontradas para o material em estudo, e conjuntamente, com as diversas curvas de tração de vários aços TWIP da empresa POSCO, realizou-se a comparação. Visto ter-se ficado reduzido a dois possíveis aços TWIP, foi através de uma análise à composição química, EDS - Espectroscopia da energia dispersa por raios-X, que se concluiu que o aço em estudo era o TWIP980. Na caraterização mecânica, e através de ensaios de tração, foram estudadas propriedades como: o módulo de elasticidade, tensão limite elástico, ductilidade, anisotropia, coeficiente de encruamento e Poisson. Estas propriedades foram estudas para três mudanças na trajetória de deformação e quatro pré-deformações em estudo. Assim estudou-se a alteração de trajetória para os ângulos a 0º, 45º e 90º em relação a RD, para as deformações de engenharia de 0%, 10%, 20% e 30%. Por último, na análise à microestrutura, esta teve como objetivo obter valores para o tamanho de grão e de macla bem como as suas orientações cristalográficas. Também a densidade de deslocações e maclação para cada uma das 4 pré-deformações esteve em estudo. Estes parâmetros foram obtidos através de microscopia ótica, eletrónica de varrimento, MEV e eletrónica de transmissão, MET.

El filosofar iuspoli(é)tico equitativista. (Una tentativa de Filosofía Política de la moral y el derecho)

Este ensayo teoriza la relaciones fuertes que toda praxis política tiene de forma consciente o inconsciente con alguna concepción concreta de la moral y del derecho. Trata así de explicitar esos vínculos en el marco de una filosofía crítica de la política, bajo la denominación de ‘poli(é)tica’ e ‘iuspoli(é)tica’ general. Para ello analiza la presencia de la actitud moral y la norma jurídica en la acción política. Estas relaciones se considera que pueden ser representadas de una forma «romboidal» más que «triangular», en virtud de la duplicidad de rasgos constituyentes / instituyentes y constituidos / instituidos de toda política respecto a las diversas concepciones de la moral y el derecho. En relación a ‘lo peor fáctico’ y ‘lo mejor posible’, construidos desde la interpretación de lo real como modelos de validez y viabilidad ejemplar negativa y positiva, finalmente se reformula la categoría de ‘autonomía’ en sus versiones iuspoli(é)ticas autodeterminista, pluriversalista y finalista y sus vertientes individual y societal. Emerge de esta manera una propuesta de filosofía iuspoli(é)tica equitativista particular que pivota sobre las categorías de legitimidad, dignidad, autonomía y equidad.

Traditional part-time grazing: a more sustainable sheep milk and cheese production in the Basque Country

[EN] The concept of sustainability when referring to food production rests, in general, on 3 main aspects: 1) respect for the environment; 2) economic and social benefits for all involved in production; and 3) production of sufficient quantity of quality food at an accessible price. In this contribution we focus on the main aspects of the traditional sheep's milk and cheese production (under the Denomination of Origin Idiazabal Cheese) in the Basque Country that contribute primarily to its sustainability. It is based on the local latxa or carranzana breeds of sheep, adapted to the mountainous terrain. The sheepherder takes advantage of local resources to reduce management costs by combining indoor dry forage and concentrates with outdoor grazing throughout lactation, according to local pasture availability, and thus avoiding having to buy large amounts of feed. This system facilitates recycling of manure, fertilising pastures and forest at the same time. Use of local breeds helps maintain biodiversity of sheep breeds. Cheese is produced industrially (44.5% of the total cheese produced in 2008) from milk of many flocks, or artisanally (38.3%) by the sheepherders with the milk from their own flocks. Transforming their own milk into cheese is advantageous for the following reasons: 1) higher economic returns as compared to selling the milk to cheese factories because cheese price directly sold to consumers is more competitive than industrial cheese sold in supermarkets; 2) increases the value of women's work (over 80% of the cheese makers are women) in the community and their self-esteem; 3) it creates rural jobs and contributes to rural development; 4) we have demonstrated both with experimental and commercial flocks that part-time grazing allows the sheepherder to obtain high yields of milk, and cheese, of high nutritional and functional quality. Currently a less sustainable, intensive sheep's milk production with foreign, imported breeds kept indoors constantly is gaining favour among milk producers because of its perceived higher economic profitability.

Polvo de lavar o Irex: incidencia de estímulos fonológicos y semánticos en la producción de palabras habladas de una paciente afásica

Se estudia la incidencia de los estímulos fonológicos y semánticos en los procesos de producción léxica, a partir de los datos obtenidos en pruebas de denominación con paciente afásica con características anómicas. Arroja datos en relación con la naturaleza del lexicón, el debate entre procesos seriales y de acceso directo y su papel en la recuperación léxica la longitud fonológica y silábica de la palabra.The incidence of semantic and phonological stimuli in word production processes is addressed. This research analyzes the results obtained from different denomination tasks with an anomic speaker with aphasia. The basis of research was a lexicon theory, the debate between connectionist or serial levels in language production, and the incidence of syllabical and phonological length in word recovery.

Estudo do processo de combustão in-situ em reservatórios maduros de óleos médios e leves (high pressure air injection)

Nearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after conventional recovery methods have been exhausted and much of this volume would be recovered by Enhanced Oil Recovery (EOR) methods. The in-situ combustion (ISC) is an EOR method in which an oxygen-containing gas is injected into a reservoir where it reacts with the crude oil to create a high-temperature combustion front that is propagated through the reservoir. The High Pressure Air Injection (HPAI) method is a particular denomination of the air injection process applied in light oil reservoirs, for which the combustion reactions are dominant between 150 and 300°C and the generation of flue gas is the main factor to the oil displacement. A simulation model of a homogeneous reservoir was built to study, which was initially undergone to primary production, for 3 years, next by a waterflooding process for 21 more years. At this point, with the mature condition established into the reservoir, three variations of this model were selected, according to the recovery factors (RF) reached, for study the in-situ combustion (HPAI) technique. Next to this, a sensitivity analysis on the RF of characteristic operational parameters of the method was carried out: air injection rate per well, oxygen concentration into the injected gas, patterns of air injection and wells perforations configuration. This analysis, for 10 more years of production time, was performed with assistance of the central composite design. The reservoir behavior and the impacts of chemical reactions parameters and of reservoir particularities on the RF were also evaluated. An economic analysis and a study to maximize the RF of the process were also carried out. The simulation runs were performed in the simulator of thermal processes in reservoirs STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator) from CMG (Computer Modelling Group). The results showed the incremental RF were small and the net present value (NPV) is affected by high initial investments to compress the air. It was noticed that the adoption of high oxygen concentration into the injected gas and of the five spot pattern tends to improve the RF, and the wells perforations configuration has more influence with the increase of the oil thickness. Simulated cases relating to the reservoir particularities showed that smaller residual oil saturations to gas lead to greater RF and the presence of heterogeneities results in important variations on the RF and on the production curves

Análisis del posicionamiento estratégico del café del Huila y el desarrollo de los cafés especiales

El proyecto de grado titulado “Análisis del posicionamiento estratégico del café del Huila y el desarrollo de los cafés especiales” tiene el objetivo general de estudiar y hacer públicas las ventajas de producir café de alta calidad en el departamento del Huila, puesto que existen algunas zonas del departamento que no tienen una producción de calidad certificada, lo cual ha generado cuellos de botella en relación a la demanda potencial y real con la Unión Europea. En la investigación se busca la manera de incrementar la zona productora de cafés especiales para satisfacer el mercado Europeo que es gustador del tipo de café que se cultiva en la región Huilense por la suavidad, aroma, entre otras variables influyentes. El desarrollo de este proyecto en esta región del país, se sustenta por la mayor producción de café a nivel nacional. Asimismo, también porque es el abanderado en cafés especiales y cuenta con la mayoría de fincas certificadas con algún sello de conducta en Colombia. Lo anterior, se ha alcanzado con la aplicación de buenas prácticas para la sostenibilidad del cultivo, la gran labor de renovación de cafetales y al don cafetero que tiene la gente del Huila debido a que es el negocio agrícola más importante.
