The wrong sizing of handle instruments can generate ergonomic problems. To know the anthropometry of the hands is indispensable for a correct sizing, especially how much the gender influences in this aspect. The objective of this study was quantitatively to evaluate the influence of the sort in the anthropometry of the hand human being. The results indicate that the differences are significant and that this factor must be considered in design of manual instruments.

Entre as diversas iniciativas que procuram aproximar a História da Matemática do ensino da Matemática, o uso de fontes primárias tem sido muito promissor. Seguindo de perto esta tendência, propomos abaixo três atividades baseadas em excertos retirados de uma obra publicada no século XVI

Conjugal problems may damage parents and children relationships favoring the appearance of behavior problems, as well as causing psychological problems. Given the lack of studies which value several interrelated behavioral repertoires, the present paper aims at presenting assessment results employing multiple instruments in regards to the three couples that sought clinical services at a University clinic. Results indicated that participants were presenting communication deficits, problem solving difficulties, and problems in expressing affection confirming literature findings. Problems in other areas were also reported, which influenced the marital relationship. It stands out that the children were presenting indications of behavior problems. The relevance of data collection applying different instruments is discussed, and it is necessary that intervention programs consider individual difficulties, besides setting up singular objectives for each person searching for service.

In this paper we present two studies, the first one completed and the second one in development, which are based in teaching approaches that propose the qualitative study of mathematical models as a strategy for the teaching and learning of mathematical concepts. These teaching approaches focus on subjects from Higher Education such as Introduction to Ordinary Differential Equations and Topics of Differential and Integral Calculus. We denominate this common aspect of the teaching approaches as Model Analysis and in a preliminary level we relate it with Mathematical Modeling. Furthermore, we discuss some questions related with the choice of the theme and the role of Digital Technologies when Model Analysis is applied.

Taking referential theoretical conceptions of mathematical knowledge present in some of the main mathematics philosophical currents and considering that the teacher´s practice is influenced by his conception of mathematical knowledge, this research aims to understand the conceptions of mathematical knowledge and its teaching and learning teaching of future mathematicians. It follows a qualitative approach (case study) in which the data were collected by semi-structured interviews and document analysis. This investigation has pointed out that Mathematics together with Mathematics Teaching (or part of this: on the didactic and pedagogical knowledge of how to teach) could be important to formation of the future mathematician, who will probably teach in a college or university.

É comum nas áreas rurais a utilização de métodos de irrigação que consistem em bombear a água de açudes, lagoas e rios para irrigar a terra onde está sendo cultivada determinada cultura. Em geral esse bombeamento é feito por motores movidos á energia elétrica ou á óleo diesel. Este trabalho visa avaliar os motores elétricos de baixa potência que são usados para irrigar pequenas áreas plantadas através de bombeamento de água de açudes, lagoas etc. Os métodos a serem usados competem á aplicação da Física e do Calculo Diferencial e Integral, através do uso de conceitos,integrais definidas e do uso de sólidos de revolução para simulação. Poderão ser feitas associações entre vazão de água, potência necessária para o serviço, a quantidade de tempo que a reserva de água sustenta o bombeamento. Depois de feito os cálculos pode se concluir sobre o tipo de motor e potencia mais adequada para tal serviço. Este projeto visa avaliar o desempenho de motores elétrico de baixa potencia no bombeamento de água através de métodos pertinentes ao calculo diferencial e integral e ao mesmo tempo poder mostrar uma das várias aplicações desta disciplina. Após os cálculos realizados espera-se obter conclusões sobre os motores elétricos e fazer a associação do serviço que é recomendado para o seu uso. Serão utilizados métodos do cálculo diferencial e Integral para a avaliação do desempenho do motor e conceitos da Física para determinação e associação entre potência dissipada e vazão de água.

Water management has in the watershed plans an important tool to plan the territory and adjust the activities develop over it to the natural resources availability. The incorporation of uncertainty analysis associated with hydrological modelling predictions is a manner to simulate scenarios and work with chances and probabilities that certain events happens inside these plans. Using stochastic methods is possible to consider uncertainty from estimations and even model it. Stochastic methods developed considerably during the last 30 years, but its applications to real-world problems have been limited, and did not turn into routine in hydrology. This paper brings an overview from eminent hydrologists about this subject and discuss the Brazilian and Paulista situation in the scope of groundwater monitoring.
