Demonstração de fórmulas matemáticas no ensino médio

The objective of this study is to analyze the validity of working with proofs in the classroom and to present a partial list of proofs of mathematical formulae of the Brazilian secondary/high school curriculum. The adaptation of the proofs into the knowledge and abilities of a secondary school student should also be considered. How the teaching of proofs is treated in official publications in Brazil and other countries is also described. Working with proofs provides a number of benefits to the students, including: the development of logical reasoning, argumentative capacity, analytical skills on a daily basis, as well as motivation and a better understanding of mathematics as a science. The convenience of including the teaching of proofs in Brazilian secondary school curriculum and the need of a balance between the abstraction of proofs and contextualization of the school programmes is discussed. The approach of the proof teaching in the classroom can become a motivating factor or, conversely, a discouraging one. The conclusion is that it would be very useful to create a reference list covering the mathematical expressions of school programmes with their respective proofs that can be understood by secondary school students.

Aplicação das fórmulas CIELAB e CIEDE2000 na avaliação da cor de folhas vegetais irradiadas por uma fonte de Cobalto-60

A cor dos alimentos está directamente associada à sua aceitação pelo consumidor. A procura de métodos de processamento seguros e eficazes destaca a radiação ionizante, já que permite a desinfecção do alimento e a extensão do seu tempo de prateleira [1]. O espaço de cor CIELAB é comummente utilizado para avaliar diferenças de cor (ΔE*) entre dois objectos. No entanto, a fórmula CIEDE2000 permite atenuar variações entre valores calculados e percepcionados [2]. O impacto da radiação ionizante na cor de um vegetal folhoso foi avaliado durante o tempo de armazenamento e os resultados discutidos utilizando ambas as fórmulas de ΔE*.

Sobre polinomios de Laurent ortogonales y fórmulas de cuadratura en la circunferencia unidad

El objetivo de esta tesis es el de unificar la Teoría de Sistemas Bi-ortogonales de Polinomios Trigonométricos (eje real), introducida por Szegö en 1963 como herramienta fundamental en el estudio de fórmulas de cuadratura con máximo grado de precisión trigonométrico y el de manifestar que las sucesiones de polinomios de Laurent ortogonales (circunferencia unidad) son la clave para el diseño de tales fórmulas.

La manera de hacer bien las visitas, fórmulas empresariales para la venta de productos de corcho. El caso de la empresa Esteva de Palafrugell

Entre la diversa documentación incorporada en el Centro de Documentación Ramir Medir Museu del Suro de Palafrugell, adquiere un especial interés para el conocimiento de la historia de la industria del corcho en Catalunya, los archivos de empresas de compra, procesamiento y de producción de maquinaria. De los diversos fondos y colecciones, se encuentra el fondo Joaquim Esteva S.A., de la empresa familiar Esteva, fundada en 1836 por Miquel Esteva Martinell, que tuvo su taller dedicado a la producción de tapones de corcho en la localidad de Palafrugell, comarca del Baix Empordà (Girona, España).

Microencapsulação de óleo essencial de laranja

It was done microencapsulation of natural essencial orange oil through spray-drying. The purpose was to use the best proportion of wall materials among maltodextrin, acacia gum, and modified starch (capsul) in order to retain greater amount of orange oil. The orange oil (10%) and maltodextrin (36%) remained constant. Three spray drying temperatures were employed: 180°C, 200°C and 220°C, therefore, nine final products were obtained. The superficial and inner oil concentrations were measured. The microcapsules were also examined through optical and scanning electron microscopy. The three temperatures employed did not affect the microencapsulation. The microstructure of the capsules were almost similar regardless the proportion employed among the carbohydrates to wall composition. At light microscopy it was observed a great heterogeneity of capsules diameters, and probably not smooth surfaces; at scanning electron microscopy it was clear that the walls displayed porosity over round surfaces. The best retention was given by the formula containing 10% of capsul, 10% of orange oil and 36% of maltodextrin, when total oil retention was 94%, regardless the drying temperature here employed.

Morphological aspects of buffaloes (Bubalus bubalis) umbilical cord

Buffalo is an important livestock resource, with a great participation in agricultural systems, providing milk, meat, and work power. Umbilical cord is responsible for maternal-fetal nutrients exchange during pregnancy, and its alterations can compromise the fetal development. We investigated ten pregnant uteruses collected from cross-bread buffaloes in different stages of gestation. Pregnancy and fetal age was determined by measuring the apex sacral length and development period was calculated by previously published formula. Umbilical cords were measured for length determination. Umbilical cord vascular net and anastomosis were observed by injection of Neoprene latex. Histological sections of the umbilical cord were studied after stain with HE, picrossirius, toluidine blue, orceine, and PAS reaction. Buffaloes' umbilical cord was formed by two central arteries, an allantois duct and two peripheral veins. The artery wall was composed by large quantity of collagen, elastic fibers, fibroblasts and large number of vasa vasorum. The allantois duct was located between the arteries and presented a great number of small nourishing vessels. Small nourishing vessels should be carefully considered to avoid to be mistaken to the arterials and veins vasa vasorum. Medium length of umbilical cord from buffalos was 11.8cm (minimum of 6.8cm and maximum of 17.4cm).

Índices de preço para o transporte de cargas: o caso da soja

Esta pesquisa objetivou analisar metodologias para elaboração de índices de preços para o transporte de cargas. O estudo das principais fórmulas da Teoria Econômica culminou com a conclusão que os Índices de Fisher e Walsh são aqueles capazes de atender ao maior número de preceitos lógicos, estatísticos e econômicos. Em seguida, surgem os índices geométricos de Törnqvist, Vartia e Theil. Os Índices de Laspeyres e Paasche, apesar de apresentarem algumas limitações, acabam sendo amplamente utilizados, graças a maior capacidade de operacionalização. A pesquisa apresentou um estudo de caso para o transporte da soja em grão. Foram realizados quatro tratamentos. Obteve-se a variação acumulada no nível geral de preços para o transporte rodoviário de soja no Brasil, no período entre fevereiro de 1998 e março de 2002. De acordo com os resultados, essa variação acumulada teria sido de 76%.
