Comportamento informacional dos docentes dos PPGCIS da região nordeste
Forte, Jofrany Dayana PessoaIt analyzes the informational demands of the PPGCIs' professors from the Northeast Region concerned with both teaching and research practice. The Sense-Making approach, by the American – Brenda Dervin, was applied in order to base the research, so as to understand the meaning the individual assign to information at the moment in which one realizes a cognitive gap, while proceeding to a determined task, configur...
Euler e o problema de Basiléia
Santos Filho, Marcos Fernando Cancio Justo dosWe began this work with the presentation of proof of Euler to the problem of Basel then we present two other most current statements when problem Basel and finaly an approach to preliminary content for the understanding the demonstrations here cited. Studied and statements presented in this document were extracted from [11] and [10].; Iniciamos este trabalho com a apresentação da Prova de Euler ao problema de B...
Existência e Unicidade dos Números Reais via Cortes de Dedekind
Pontes, Kerly MonroeThis work aims to show the existence and Uniqueness of the field of Real Numbers, using for this, Dedekind' Cuts theorem and the Definition by Recursion.To fulfill his goal, we define the notion of Dedekind Cut and present some of its properties; then introduce the notions of Archimedean Ordered and Field, Complete Field Sorted and finally articulate and demonstrate the Uniqueness Theorem of Field Real Numbers....
Competências gerenciais na indústria: Analisando a relação entre o prescrito e ...
Soares, Sabino de AlmeidaWe live a historical moment where the management model based on Taylorist-Fordist assumptions, subdivision of jobs and prescription activity appears to no longer meet the demand needed to face a new business reality. It is in this context that intensify the debate about the model of management skills and the work of managers, seen as essential for the introduction of this new model. Based on these characteristi...
Criptografia RSA e a Teoria dos Números
Lima, Roberval da CostaIn this work we present the concept of cryptography, highlighting the differences between symmetric encryption and asymmetric encryption. We also show how RSA encryption works. Moreover, we study the main mathematical results that justify the operation of this cryptosystem and its security, such as: congruences, Euler's theorem, Fermat's Little Theorem, Wilson's Theorem, Euler's criterion for quadratic residues...
Sobre o número Pi
Dantas, Marcelo Rodrigues NunesFor more than 2500 years, many of the great mathematicians interested in the nature and the mysteries of fascinating number Pi , wonderful minds such that Archimedes, Euler, Gauss, Abel, Jacobi, Weierstrass, among others. In this work we will study some of the fundamental properties that characterize the number Pi. We begin our work, proving that the ratio between the length of an arbitrary circumference and it...
Números complexos: um pouco de história, ensino e aplicações
Costa, Antônio Geraldo Lacerda daWe present the main properties related to complex numbers. We justify as the history of mathematics can contribute to learning that content. Then we describe briefly the history of complex numbers. We also show where the complex numbers can be applied both within mathematics itself, and beyond.; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES; Neste trabalho apresentamos as principais propri...
Representações Sociais de três gerações acerca da ditadura Militar e da comissã...
Delfino, Elluênia Lucena ClaudinoIn 2012 the national truth commission in Brazil was sanctioned to work for two years, with the objective of investigating human rights violations and appointing the people responsible for killings, torture and disappearances during the military regime. In 2014, on the 50th anniversary of this period, the committee should release reports. In this context, the study has the general objective of analyzing the soci...
Neuroestimulação no tratamento do acidente vascular cerebral: ensaio clínico, d...
Andrade, Suellen Mary Marinho dos SantosTraditional treatment after stroke includes medications and physical rehabilitation, which is generally composed of non-systematic protocols, which hinders its replicability. The transcranial direct current stimulation (tDCS) associated with a standardized physical therapy may represent an effective therapeutic alternative for these patients. The objective of this study was to analyze the effects of tDCS, combi...
Alienação parental: uma explicação pautada em traços de personalidade e nos val...
Carvalho, Thayro AndradeThis dissertation aimed to know if the personality traits and human values are able to explain the maternal alienating practices. Specifically, we intended to: (1) develop and know the psychometric parameters of the Inventory of Maternal Alienating Practices (IMAP); (2) verify the confirmatory validity of IMAP; and (3) test an explicative model, in which the personality traits and values are predictors of mater...
