The dental trade has offered dental impression and dental stone for orthodontic use ensuring accurate models. The compatibility between these materials is defined by the wetting of the model surfaces by the mixture water/stone poured over it and the influenced by the method of disinfection of model and disinfectant solution used. It was evaluated the influence of spray disinfection with sodium hypochlorite 1% on the wettability of two commercial alginate (Jeltrate ® - Dentsply and Orthoprint ® - Zhermack) at two commercial type III gypsum (Rio ® - ME and AOBussoli Orthogesso Orthogesso ®-SA). Twenty models were fabricated for each type of alginate, which were divided into two groups (water and sodium hypochlorite), receiving respectively water and sodium hypochlorite 1% spray. Each group of models was then further divided into two subgroups, and on their surface were poured 2 ml of type III gypsum (Gesso Rio® or Orthogesso®). Reached the final setting of the gypsum specimens were sectioned vertically and medially, settled water with sandpaper No. 400 and mounted on suitable device for reading (in the right and left) of the contact angle Carl Zeiss microscope (precision, 001). The results were submitted to ANOVA and founded statistical significance for solutions used. It was concluded that sodium hypochlorite spray improved wettability of alginates studied.

The dance content in Physical Activity Program for third age - PROFIT carried out at UNESP – São Paulo State University has begun in 1997 and is until nowadays a regular physical activity practice to elderly. Since beginnings the dance practitioners work with functional capacities through choreographies, claiming the spatial-time orientation, besides the benefi ts already proved by music uses. Since then, life with dance became a strong way to promote health, trough learning a variety of movements and diff erent rhythms. Today, about 30 elderly advantages besides motor part, dance classes favor body consciousness, mental practice and rhythm. The classes are divided in warm up and stretching phase, principal phase (witch components of functional capacity are stimulated) and fi nalize with cool down phase. The dance program created to physical educations undergraduate students’ opportunities to pedagogical practice and permitted researches development about aging and its relation to physical activity through dance. There are a lot of published results, collaborating with the scientifi c literature about the benefi ts of dance regular practices.

A presente invenção refere-se ao desenvolvimento de um nanocompósito de biocelulose e dietilditiocarbamato (CB-DETC) que é formado por uma matriz polimérica de celulose bacteriana com nanofibras revestidas com derivados de dietilditiocarbamato no preparo de um biocurativo para o controle de Leishmaniose Tegumentar. As principais propriedades observadas nesse biocompósito são a sua flexibilidade, fácil aplicação em lesões cutâneas, capacidade leishmanicida, ausência de toxicidade e liberação sustentada do composto ativo, reduzindo a necessidade de troca do curativo.

This articles aims to approach the possibilities of holograms utilizations on three-dimensional that, while explored, allow the improvement of the spatial visualization ability. A hologram is a three-dimensional image recorded by laser that results in an image of three dimensions from the essential use of light.

The Experimentation in Science Education is used since the beginning of 19th century and has it origins linked to the laboratory classes realized in the universities. This classes used, and in many cases, still using the Scientific Method initially purposed by Descartes in 18th century for the construction of scientific knowledge. One of the allegations is that the method would be the fast stand the cheapest to generating scientific information, although, it is based on the empiricism-positivism, which considers that all people have the same learning skill and they can start from the same spot. Through this paper, is not intended to contest the scientific methodology, or even its importance in science history, but just try to identify and describe other possibilities in using of the teaching laboratory, which can make the learning easier for a much higher number of students, contemplating different cognitive capabilities and generating a better scientific knowledge learning and its transfer to practical situations in life, besides, they can provide more significant learnings. Over the text, four different purposes will be presented, which depart from the laboratory use for theory evidence, incapable to make students use the learned knowledge outside the school, until that which develops in the students capabilities to scientifically argue about their day to day themes

A crescente conscientização da água como bem de alto valor econômico, social, cultural e ecológico exige cada vez mais o uso racional desse recurso baseados em parâmetros técnicos que levem a um aumento da eficiência do manejo de irrigação. Utilizou-se o programa STELLA 10.0.3 para simular o balanço hídrico de um solo cultivado com meloeiro (Cucumis melo L.) no município de Iguatu/Ceará. Os parâmetros meteorológicos corresponderam aos valores diários de temperatura máxima, temperatura mínima, temperatura média e radiação solar no topo da atmosfera. Utilizou-se o método de Hargreaves-Samani para determinar a Evapotranspiração de Referência. A capacidade de campo, ponto de murcha permanente, densidade aparente, profundidade efetiva do sistema radicular e o déficit hídrico tolerável foram os parâmetros físicos do solo para determinar sua capacidade de água disponível e o nível mínimo de água disponível. As irrigações são realizadas sempre que o nível de umidade do solo fica muito próximo ou abaixo do nível mínimo de água disponível. Os resultados mostraram que o modelo desenvolvido utilizando dinâmica de sistemas, analisa todos os parâmetros envolvidos de forma sistêmica e dinâmica fornecendo como resultado valores de lâminas de irrigação a serem aplicadas e os momentos em que sua aplicação é necessária.
