Crescimento de mudas de Dipteryx alata Vogel. em função da restrição radicular

Honorio, Ana Beatriz Marques 19 December 2017 (has links)
O Cerrado é o segundo maior bioma do país, ocupando cerca de 23% do território nacional, sendo superado em área apenas pela Amazônia. Possui uma vegetação com diversas fitofisionomias, tendo a mais rica flora dentre as savanas do mundo, as frutíferas do Cerrado são espécies de diversos gêneros e famílias, produzindo frutos de interesse para alimentação “in natura” quanto para industrialização como também são fontes de alimentos para os animais, a espécie arbórea Dipteryx alata Vog. apesar da sua irregularidade na produção de frutos, possui alta produtividade, facilidade no transporte e armazenamento dos frutos e a qualidade do produto, assim O presente trabalho teve como objetivo avaliar características de crescimento e parâmetros fisiológicos de mudas de Dipteryx alata Vog. em diferentes tamanhos de recipientes sob condições de viveiro no Sul do estado do Tocantins idades diversificadas após o transplantio. Em condições de viveiro foram plantadas sementes de baru em sementeira de areia, quarenta dias após as plântulas foram transplantadas para recipientes de tamanhos diferenciados. Permaneceram durante dez dias em condições de 75 % de sombra para que houvesse a aclimatação das mudas, após esse período foram transportadas para condições de 50% de luminosidade. O teste foi instalado em delineamento inteiramente casualizado. Aos 30, 60 e 120 dias após o transplantio para a coleta das variáveis fisiológicas, foi utilizado o analisador de gasses infravermelho portátil (Irga – Infra Red Gas Analyser), modelo Li – 6400XT (Portable Photosynthesis System – LI) da LICOR, em datas semelhantes a coleta dos caracteres morfológicos. Para as análises de crescimento, os dados de diâmetro do colo e altura foram coletados com paquímetro digital com 0,001 mm de confiança e régua graduada. Ao final do experimento foram coletados materiais para análises de matéria seca de raiz e parte aérea, como também feita a relação raiz por parte aérea, os dados então foram analisados a partir do software Assistat 7.7. Após rodar a análise de dados constatou-se que para as análises de crescimento assim como as variáveis fisiológicas, os recipientes de maior volume (20x30 cm) condicionaram melhor meio para o desenvolvimento das mudas. / The Cerrado is the second largest biome in the country, occupying about 23% of the national territory, being surpassed in area only by the Amazon. It has a vegetation with several phytophysiognomies, having the richest flora among the savannas of the world, the fruit of the Cerrado are species of diverse genera and families, producing fruits of interest for food "in natura" as for industrialization as well as sources of food for the animals, the arboreal species Dipteryx alata Vog. in spite of its irregularity in fruit production, it has high productivity, ease in transport and storage of fruits and product quality, as well. The present work had the objective of evaluating growth traits and physiological parameters of Dipteryx alata Vog. in different sizes of containers under nursery conditions in the South of the state of Tocantins diversified ages after transplanting. Under nursery conditions baru seeds were planted in sand sowing, forty days after the seedlings were transplanted to containers of different sizes. They stayed for ten days under conditions of 75% shade for acclimatization of the seedlings, after that period they were transported to conditions of 50% luminosity. The test was installed in a completely randomized design. At 30, 60 and 120 days after transplanting for the collection of the physiological variables, the portable infrared gas analyzer (Irga - Infra Red Gas Analyzer), model LI - 6400XT (Portable Photosynthesis System - LI) of LICOR, was used on dates similar to the collection of morphological characters. For the growth analyzes, the data of diameter of the neck and height were collected with digital caliper with 0.001 mm of confidence and graduated ruler. At the end of the experiment, materials were collected for analysis of dry matter of root and shoot, as well as the root ratio for aerial part, the data were then analyzed from Assistat software 7.7. After running the data analysis it was verified that for the growth analyzes as well as the physiological variables, the containers of larger volume (20x30 cm) conditioned better medium for the development of the seedlings.

Wearable Technology for Presumptive Diagnosis of High Blood Pressure Based on Risk Factors

Prada, Eithel Josue Meza, Agullar, Helgar Miguel Angel Herrera, Armas-Aguirre, Jimmy, Gonzalez, Paola A. 01 January 2021 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / In this paper, we propose a technological solution integrated to a wearable device that allows measuring some physiological variables such as body mass index (BMI), steps walked in a determined day, burned calories, blood pressure and other risk factors associated with the Framingham´s score. The objective of this article is to identify the evolutionary pattern of the Framingham’s score each day in order to determine a presumptive diagnosis of high blood pressure. The technological solution was validated in the social insurance of a public hospital in Lima, Perú. The preliminary results obtained in a diagnostic test show a sensitivity level of 83.33%, a level of precision better than a traditional Framingham´s score for presumptive diagnosis of high blood pressure. Our proposal contributes to the patient’s awareness about the bad routine habits related to lifestyle and promotes the empowerment of data in order to make some changes that influence on the reduction of cardiovascular disease risk. / Revisión por pares
