Evaluación cuantitativa de la firmeza de baya en uva de mesa

Brayovic Piñones, Milenka Mariot 10 1900 (has links)
Tesis presentada para optar al Título de Ingeniero Agrónomo y Grado de Magíster en Ciencias Agropecuarias Mención Producción Frutícola / En la industria de la uva de mesa, es fundamental adaptar y calibrar el uso de instrumentos, de manera de objetivar las evaluaciones de firmeza de bayas de los racimos. Con este propósito, se evaluó la firmeza de bayas en las variedades Flame Seedless, Superior Seedless, Red Globe, Thompson Seedless y Crimson Seedless, por medio de dos instrumentos: Firmtech 2® y medidor de torque Torque Load Sensor®. Con la ayuda de personal experimentado, cada variedad fue cosechada por su condición de firmeza, diferenciándose tres categorías: racimo firme (RF), racimo medianamente firme (RMF) y racimo blando (RB). Inmediatamente, en el Laboratorio de Viticultura de la Facultad de Ciencias Agronómicas de la Universidad de Chile, se realizaron los análisis de firmeza (g·mm-1) de todas las bayas de los racimos por medio de Firmtech 2®. Luego se escogió una muestra representativa de bayas de cada sector del racimo (superior, medio y distal), donde se realizaron evaluaciones de peso fresco (g), largo (mm), ancho (mm), firmeza de pulpa (N·cm) con el instrumento Torque Load Sensor®, concentración de sólidos solubles (%) y peso seco (g) de cada baya. Además, en la variedad Thompson Seedless, se determinó la correlación entre Firmtech 2® y Durofel®, con150 bayas seleccionadas al azar. Los resultados indican que existen diferencias significativas entre los tres tipos de racimos seleccionados (firmes, medianamente firmes y blandos), en todas las variedades, excepto en Superior Seedless, donde sólo se diferenció el racimo firme del blando. Las diferencias entre sectores del racimo (superior, medio y distal) no fueron significativas en ninguna variedad. Las correlaciones entre firmeza y los diferentes parámetros medidos, en general, fueron bajas. Sin embargo, destaca la asociación entre firmeza de baya y pulpa (r=0,66), en la variedad Thompson Seedless. La asociación entre la firmeza de baya medida con Firmtech 2® y Durofel® es alta (r = 0,76) y significativa. Estos resultados permiten concluir que la firmeza de baya es un parámetro posible de objetivar y las diferencias existentes pueden determinar rangos de firmeza específicos para cada variedad.

Significados da prática de jogo de mesa para idodos de Fortaleza-CE / Meanings of gaming practice for elderly in Fortaleza-CE (Inglês)

Terceiro, Amadeu de Sousa Moura 21 September 2016 (has links)
Made available in DSpace on 2019-03-30T00:13:17Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-09-21 / This study aimed to investigate the meanings of table game practice for Fortaleza elderly. It started from the premise that aging should be marked by the attempt to fill the time in a more enriched way in which the game is included as culture and activity practiced by the elderly during their free time. For this investigation, we interviewed older players and regulars from Argentina Castelo Branco square at Fatima neighborhood in Fortaleza. The ethnographic approach discussed during the qualitative methodological approach has supported monitoring the group of old players of that square, where their routine was observed and their behaviors in order to describe and understand the meanings of table game practice for them. The data collection instruments used were: (a) participant observation and (b) in-depth interview. In addition to the analysis of ethnographic account, we used the technique of the Collective Subject Discourse (DSC), of Lefèvre and Lefèvre, for grouping speech categories, where three of the material analysis instruments (IAD-1, IAD-2 and IAD -3) were generated facilitating the process of analysis. The results show that the meanings attributed by the elderly their practice game relate to a time to spend, leisure time, time to socialize and feel pleasure; Furthermore, the game practice arises as a usual activity, seen as a palliative for health. Thus, it appears that the meanings attributed by the elderly to the practice of board game are several confirming the assumption that there is, indeed, a polysemy of possible meanings. Keywords: Play. Elderly. Experience. Flow. Recreation. / Este estudo teve como objetivo investigar os significados da prática de jogo de mesa para idosos de Fortaleza-CE. Partiu-se da premissa de que a velhice deve ser marcada pela tentativa de preencher o tempo de maneira mais enriquecida, no qual o jogo se insere como cultura e atividade praticada pelo idoso durante o seu tempo livre. Para esta investigação, foram entrevistados idosos jogadores e frequentadores da Praça Argentina Castelo Branco no Bairro de Fátima em Fortaleza-CE. O enfoque etnográfico abordado durante o percurso metodológico qualitativo deu suporte a um acompanhamento junto ao grupo de idosos que praticam atividades de jogo da referida praça, onde se observou a rotina dos participantes e seus comportamentos com o intuito de descrever e compreender os significados da prática de jogo de mesa atribuídos por estes. Os instrumentos de coleta de dados utilizados foram: (a) observação participante e (b) entrevista em profundidade. Para as análises dos dados utilizou-se do relato etnográfico elaborado, além do Discurso do Sujeito Coletivo (DSC) para o agrupamento de categorias, onde três instrumentos de análise do material (IAD-1, IAD-2 e IAD-3) foram gerados facilitando os processos de análise. Os resultados mostram que os significados atribuídos pelos idosos a sua prática de jogo dizem respeito a passar o tempo, momento de lazer para sociabilizar-se e satisfação; além disso, a prática de jogo surge como um costume, descontração e ludicidade. Com isso, infere-se que os significados atribuídos pelos idosos à prática de jogo de mesa são diversos, confirmando o pressuposto de que há, de fato, uma polissemia de significados possíveis. Palavras-chave: Jogo. Idoso. Experiência. Fluxo. Lazer.

Angular Dependence of the Emission from the Intrinsic Josephson Junction in Pie-Shaped Wedge Triangular BSCCO Mesas

Morales, Manuel 01 May 2015 (has links)
The purpose of this thesis is to determine the radiation patterns from an acute isosceles triangular superconducting mesa modeled by a pie-shaped geometry. The terahertz band lies between the microwave and infrared regions of the electromagnetic spectrum. The terahertz radiation from atomic-scale layered superconducting mesas is caused by the tunneling of electron pairs in the ac-Josephson effect. To determine the terahertz power radiated per unit solid angle of an acute isosceles triangular superconducting mesa, a model was employed in which the shape of the mesa is approximated as a pie-shaped wedge. This model is shown to have an accuracy of about 1%. Using Love’s Equivalency Principle, the current caused by the Josephson effect is then assumed to be on the edges of the mesa. Since in the mesas used for experiments the electric field is in the direction of the current, it is parallel to the boundary of the sample. Hence, we want the TM modes, and that requires the magnetic field to be transverse to the boundary. We thus require that the tangential component of the magnetic field parallel at the boundary vanishes. Love’s equivalency principle provides the easiest and most straight forward way to satisfy this condition. The surface electric current density was modeled by comparing the magnetic vector potential resulting from the modeled edge current with that given by a standard volume average integration technique. The surface current density that provided the best approximation to the bulk average was used and the radiation patterns were plotted using Mathematica software.
