Tendo como foco as múltiplas escalas de tempo que atuam na Amazônia, este trabalho foi desenvolvido com o objetivo de investigar a possível influencia da Oscilação Madden – Julian (OMJ) em elementos turbulentos da CLP. A OMJ foi identificada a partir de 30 anos de dados de reanálise de radiação de onda longa (ROL) e componente zonal do vento (u). As grandezas turbulentas foram estudadas a partir da variância, covariância e coeficiente de correlação de um conjunto de dados de resposta rápida coletado na torre micrometeorológica de Caxiuanã (PA), e tratados com a Transformada em Ondeletas (TO) para se obter a contribuição de cada escala para estes momentos estatísticos. A análise dos 30 anos de dados de ROL e u mostrou que a ocorrência da OMJ está ligada com o fenômeno do El Niño/Oscilação Sul (ENOS), bem como influência do ENOS no tempo da região amazônica pode estar associado a presença ou não da OMJ. Foi observado que anos de El Niño tendem a desfavorecer a ocorrência da OMJ e anos de La Niña tendem a favorecer o desenvolvimento da oscilação. Caso uma OMJ se desenvolva durante um episodio de El Niño, a oscilação pode influenciar a temperatura, a velocidade do vento e a precipitação de forma diferente ao do El Niño. A análise por fase da OMJ mostrou que, em Belém, há diferença significativa na temperatura máxima e na precipitação entre cada fase, porém, a temperatura mínima e o módulo do vento apresentaram pouca diferença. Os fluxos cinemáticos turbulentos analisados, por escala, em três horários distintos, foram mais diferentes durante o período diurno, principalmente w’T’ e w’q’. A diferença entre fase ativa e fase inativa foi reduzindo com passar do dia, durante o período de transição dia – noite, poucas escalas tiveram diferença significativa, e durante a noite, nenhuma escala teve nível de confiança acima ou igual a 95%. Estes resultados indicam que a convecção diurna é o mecanismo responsável por esta diferença e como a OMJ atua como uma grande célula convectiva, a convecção local é amplificada, explicando a grande diferença observada entre as fases durante o período diurno.

Discusses the interconnections between information management and knowledge management for themanaging of information flows. Starting at a literature review to obtain a grounding that allows clarifythis question. Presents the peculiarities involving the formal flows management [informationmanagement] and informal flows management [knowledge management], as well as factors thatprovide a better understanding in regard to the focus of information management and knowledgemanagement. The efficient information flows management demands the need to deploy the informationand knowledge management to its true effectiveness. We can see that these two modes of managementare interrelated such that, in the absence of a, the other is affected, directly impacting the informationflows management and thus in the organization capacity to create knowledge and make decisions withcompetitive differential.

Information flows are responsible for the dynamics and the interaction between the various sectors of the organization and among individuals who work in it. By mapping performed in internal and external environments of the organization, it is possible to highlight the informational needs of organizational individual, since they depend on data, information and knowledge to perform their actions in the corporate environment. To meet the information needs of organizational individual need to manage the existing information flows, how it can settle and move effectively in the organizational environment. It is argued that the environments and existing information flows in an organization, subsidize the process of organizational competitive intelligence, since they are inputs for decision making and enable the planning and execution of actions in the short, medium and long term.

This work aims to evaluate the different trajectories in terms of production structure, technological capabilities and performance in international trade of pharmaceutical industries in Brazil and India. For this, we build international trade indicators, based on data provided by the COMTRADE, the UN database for trade. Through the indicators, it is observed that the countries have different results in the catch-up process of the pharmaceutical industry. India has built a productive structure strongly based on generic drugs, with which it is able to greatly meet domestic demand and export to many countries worldwide. Brazil remains in a position of dependence of foreign production, with a high level of imports and exports to the region of Latin America

The present study represents a qualitative thesis, characterized as a case study, which uses the method of the present approach. In addressing the academic home in physical education, there is the constancy of the discussions regarding the curriculum and professional formatting. In view of the curriculum modifications to fit the new legislation, and the fact they are few studies related to private institutions that offer such courses, which offer even greater number of courses when compared to public institutions aimed to investigate and analyze the professional profiles, curricular goals and flows contained in the pedagogical projects of courses bachelor degree in physical education and a private institution of higher education of the State of São Paulo, as well as verifying the existence and adequacy of articulation to the institutional educational project and the institutional development plan. Compounding the literature review discussed the key historical facts relating to courses in physical education in our country, and its path to the current model. Also presented was the law of physical education courses in force in Brazil and some concepts about teaching course projects and their relationship to other institutional documents. Techniques were used to review and document analysis, with primary source documents of their own and other government institution. It found a lack of interest of some private institutions of higher education in official documents available for this type of research, which is bad since there are more courses offered by them compared to public institutions. As for the degree course for training teachers of physical education, found lack of specificity regarding the differentiation between content and the bachelor, which ends up deviating from the expectations contained in the course to the one presented in the curriculum. Thus, it becomes a need for greater collaboration of private institutions of higher education...
