Formas diferenciais

In this work, studies aimed at evaluating the unification of concepts and theorems of vector analysis that contributed to the understanding of physical problems in a more comprehensive and more concise than using vector calculus. We study the electrodinamics with differential forms. Were also presented Maxwell's relations with formalism of differential forms in addition allowing formulation one more geometric and generalized. Another feature observed during the study of formalism presented was the possibility of it serving as a substitute to the tensor formalism

Estudo de uma ponte rolante comercial no transportede bobina de aço de 12 toneladas

This work aims to determine the stresses acting on the main beam of a crane to transport steel coils of up to twelve tons. To determine the stress it was made a revision of the knowledge of the mechanics of materials to apply the analytical method. Following a review of the finite element method is made to understand the same. To complete the study it was used the commercial software ANSYS to determine the stresses by finite element method, the program provides images that help to better understand the results obtained. With the results a comparison of the values of the tensions between the two methods (analytical and finite element) was made. To assist in the calculations it was used the NBR 8400, 1984 (Calculation of Lifting Equipment Load)

Introdução à gravitação de Brans-Dicke

The cosmological standard model needs a deep improvement when compared to recent observational data and also when contrasted with a broad theorical context. Al- ternative theories to General Relativity are possible candidates to reach the expectation Physics of Elementary Particles and Gravitation. Scalar-tensor theories seem to reappear from the ashes of the old work by Jordan corresponding appropriately low power limits of unifying theories. Being the Brans Dicke theory a scalar tensor is conducted a comprehensive study starting from its rst motivations to it s current one it is re flections

Enfermagem e o gerenciamento de custos: revisão sistemática nacional e internacional

Objectives: conduct a systematic review of national and international literature, to classify the types of production, comparing the two literatures and synthesize knowledge in the area. Method: Systematic Review of Literature, in the databases LILACS, CINAHL and MEDLINE for selection of articles in their entirety, the data extracted from the articles selected were: the study of bibliographic information (title, author, journal, place of study and year of publication), and general information (multidisciplinary production or specific area, language, type of study, type of population and contributions of the study). The categories established for classification of publications were: raising the cost of procedures/ interventions, economic evaluation of specific intervention, inclusion of nursing in the economic context, using cost as an important variable in the study. Results: The study included 39 publications, with 31% of national production and the remaining 69%, internationally. Most publications were classified according to category of economic evaluation of specific intervention, followed by the category of raising the cost of procedure / intervention, which fits the majority of national production. Human resources is shaped as an important variable for obtaining cost studies that proposed to make this calculation. Conclusion: The production of literature in nursing cost management is relevant in number of publications within the proposed period and is directed to different areas within this theme. There are significant differences in national and international literature: these last use more accurate methods, have more content theorized, use more the economic evaluation tools and related more costs with a amplified context. The production of such knowledge should continue as far as possible and putting that knowledge relating the current reality, in order to amplify the field of nursing and add value

Diagnóstico dos casos de aprovação nas disciplinas de cálculo diferencial e integral I e II do curso de licenciatura em química - Unesp de Araraquara

Studies show that the disciplines of differential and integral calculus have high failure rates in all schools where they are present and, although this problem has been accentuated in recent years, it is not a local phenomenon. It's observed since 1970s in various Institutions of higher education in Brazil. These studies seek to understand the causes of failures and proposals for teaching methodology that aims to help reduce these rates. However, there is a large contingent of students who are successful at the first time that they perform these disciplines. And these cases, although they have not been studied, can contribute greatly to the understanding the aspects that are related to learning of them. And this understanding can lead to attitudes and learning and teaching methodologies that promote the expansion of this success. The fact that these subjects also have high failure rates in the Degree in Chemistry of this Institute, this study aimed to investigate the factors that were relevant to the cases for approval of the students performed for the first time. For this we constructed a questionnaire containing objective questions and open answers. The objective sought to diagnose the profile of these students with regard to age, gender, basic education (elementary and middle school), study habits, concurrent activities, among others. These questions were analyzed using simple statistics. The open-ended questions asked students to indicate that they attribute the success obtained in the disciplines and to suggest modes of study. These questions were analyzed using thematic categorization, a method of content analysis. This questionnaire was completed, voluntarily and without identification, by students who have passed the first time attended the courses Calculus I and/ or Calculus II and had never started another college prior to this. The results indicate that the most relevant factors in this process were dedication and correct habits...

Avaliação da orientação motivacional de metas na modalidade do futebol

This study aimed to evaluate and compare the motivational goals orientation of task and ego for students belonging to two distinct environments sports football, a Private School of Sport and Non-Governmental Organization (ONG), both located in the city of Osasco - SP. Through a descriptive research we applied a scale TEOSQ to a sample of 196 subjects of both sexes aged between 7 and 17 years (mean 11.16 +2.09) and the data were treated with the calculation of Alpha´s coefficient, mean, standard deviation, median, and the averages compared with the Mann-Whitney test. The results showed stability in the instrument with alpha of 0.78 and 0.68 for the task of self in school´s sport with an average of 4.28 of task and 2.40 of ego, since the ONG´s Alpha task was 0.74 and 0.60 of Alpha´s ego with an average of task and ego of 4.40 and 2.75 respectively. We conclude the tendency for task-oriented with students predisposed to overeat constantly, and reliability of the instrument.

Avaliação dos parâmetros do índice de qualidade de água segundo o modelo ARIMA

Time series tendencies are an important tool for different sectors such as the scientific community, industries and environmental protection agencies who can evaluate the variability of a specific parameter in time, what is very important piece of information for establishing corrective and preventive actions. This work presents a time series model of main physical, chemical and biological parameters of the Water Quality Index (WQI) determined for different selected points of a hydrographical basin form May/2006 to Aug/2010. The statistical model Arima enabled a better understanding of the physical, chemical and biological processes that most clearly influences WQI. The Arima model allowed the assessment of the trend of several parameters used in the calculation of the WQI, showing that dissolved oxygen, turbidity, total nitrogen, and fecal E. coli were highly correlated and are the parameters that caused the index changes over time.

Aplicação de métodos matemáticos no dimensionamento da potência necessária para a irrigação através de motores elétricos

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.
