Information and Communication Technologies inserted in the context of mathematics teaching can promote greater participation and involvement of students with the contents covered. New technological tools emerge in a continuous and rising frequency, inserting them in the educational context and making optimal use of their resources is the role of the school and its actors. This research presents the results of a study that investigates the development and use of Augmented Reality in mobile applications in Basic Education Mathematics classes. To this end, an application was developed on the Android platform that allows the approach of the theme: regular solids, also known as Plato solids. The survey was conducted through a questionnaire used by a group of math teachers and undergraduate students of a full degree course in mathematics revealing that few had contact with this type of application, and also indicates that to combine mobile devices augmented reality resources denotes being relevant for approaching geometric solids.

Entidades de todo o mundo estao cada vez mais fortalecendo movimentos em prol de um planeta mais saudavel e sustentavel. Neste sentido, o intuito deste trabalho e a construcao de nanofibras de C/BiVO4 via eletrofiacao e posterior carbonizacao do polimero PVA. Obtendo assim, nanofibras com elevada area superficial quando comparados aos usais metodos de deposicao. Possibilitando maior absorcao dos fotons e consequentemente elevando a eficiencia fotoeletrocatalitica na conversao energetica e degradacao de poluentes orgânicos. O BiVO4 sintetizado foi caracterizado e assim confirmado a formacao da fase monoclinica. A tecnica de eletrofiacao apresentou fibras com diâmetros na escala nanometrica com a presenca do carbono, aumentando consideravelmente a area superficial do material, confirmado pelas microscopias optica e eletronica de varredura.

: In an increasingly competitive economic environment companies have been invested in innovation and cost reduction. The use of logistics solutions has shown a good alternative to reduce maintenance costs and improving service levels. The use of vehicle routing methods can be considered as one such instrument. In this paper was presented a maximum time-constrained vehicle routing problem, which identifying and implementing in C/C++ an algorithm that uses mathematic programming, heuristic and metaheuristic techniques. The adopted method obtains a solution that reduces eight to six steps performed by the company. In addition, a Simulated Annealing simulation improves 10.71% over an initial solution considered with the next closest item heuristic and 13.80% over an initial solution used in the exact method.

The soda is one of the most consumed products in Brazil. Because it contains phosphate ions in the composition, uncontrolled intake of the phosphorus mineral can cause hyperphosphatemia. Therefore, the objective was to evaluate phosphate in soft drinks of different types and to investigate if they are suitable to be consumed according to the daily recommendation with the aid of the visible spectrophotometry technique for non-alcoholic beverages. According to the results, only guaraná type soda has been in compliance with current legislation, which allows up to 0.07% phosphate, and safe for daily intake for healthy adults. Already the cola-type soda resulted in total disagreement with legislation and completely unsuitable for

This work objective was to verify the process of Presidente Prudente urbanization related to the unavailability of full sanitation, which was able to develop a contamination of groundwater, using as indicators of water quality, chemical and microbiological parameters such as pH, conductivity, nitrate concentration as well as fecal and total coliforms. In order to do so, the research was based in its methodology by a bibliographical analysis about the problem outlined in this work, and later developed through experimental research carried out in the peripheral regions located on the eastern zone of the city. Thus, there was obtained results that demonstrate the presence of undesirable chemical and microbiological compounds, focusing on the inadequacy of albuminous nitrogen and fecal and total coliforms.

This present work was studied the development of a molecularly imprinted polymer (MIP) based on the poly(azo-Bismarck Y) for detection of uric acid. The film MIP was electrodeposited on the fluorine-doped tin-oxide (FTO) glass electrode surface by electropolymerization of Bismarck Brown Y monomer in presence of uric acid as the template molecule. The MIP-poly(azo-Bismarck Y) sensor displays a good electrochemical response, high sensitivity and selectivity in specific binding of the uric acid. Under the optimized experimental conditions, the voltammetric response of the proposed sensor was linear in the concentration range of 0.20 mmol L to 0.60 mmol L, with detection limit of 0.17 mmol L.
