Reflexões sobre metodologia aplicada na construção de pesquisas científicas na área de comunicação social

The questions arise about the teaching and practice of the methodology of communication research. The aim is to reflect on the possibility of building research projects and develop research and scientific production in the area of social communication at the graduate level, articulating the epistemological interfaces, methodical, theoretical and methodological techniques for design of empirical research in communication, developed by Lopes (2010), adapting it to the Spiral model of knowledge creation, developed by Takeuchi and Nonaka (2008), to support the learning of the methodological procedures that involve scientific research in communication.

Contribuições à análise de qualidade do jornalismo na comunicação pública digital

Scientific research has shown remarkable advances in the formulation of criteria for assessing the quality of journalism practiced in the commercial media and public broadcasting, comprising aspects such as management models, business principles, parameters to the assessment of results and exercise of social responsibility. However, there are fewer investigations on the practice of journalism in digital public communication formats explored by government web portals. The contribution of this paper lies in a proposal of elements for the construction of parameters for evaluating the quality of journalism in the digital public communication. The proposal is inspired by criteria for evaluating the quality of commercial media and public broadcasting and suggests means for its application in the journalism practiced in the context of government web portals.

Análise da implantação

his article is the result of an empirical research on the technology and market development resulting from the deployment of Digital TV in Brazil. Two aspects were selected to discuss the proposed question: the economic and political motivations that led to the digitization of broadcast TV in Brazil and the preliminary analysis of the effects on popularization of cyberculture in the Brazilian audiovisual scenario, changes can be observed in the production, dissemination and enjoyment of audiovisual content. For the development of the analysis the following theoretical and analytical tools were used: Theory Empirical Approach (Wolf, 1987), the Cultural Studies (Zallo, 1988; 1992), the digitalization media process (Lemos), the transition from television to cyberculture studies (Manovich, 2005) and (Fechine, 2013).

A enxertia na cultura do maracujazeiro: aspectos anatômicos, bioquímicos e fisiológicos

Due to the expansion of orchards, problems with soil pathogens are frequent and cause injury and/or make passion fruit cultivation impossible in Brazil. Thus, studies with potential species for rootstocks become indispensable to assist in the technological development of the culture. It is necessary to take into account several aspects of grafting, for the adoption of appropriate techniques, among them we can highlight the anatomy, physiology and also biochemistry. This study aimed to review the existing papers related to grafting of passion fruit and also to understand the operation of grafting itself. It was observed that several publications are related to the topic of the present review and that grafting is a viable alternative to the cultivation of passion fruit, however additional studies about grafting and production are needed.

Análise do processo de construção de um ambiente constituído por garrafas pet

O desenvolvimento tecnológico crescente associado a profundas mudanças no modo de vida contemporâneo tem gerado volumes de rejeitos cada vez maiores. Um desses rejeitos são as garrafas feitas de PET. Essas garrafas podem ser aproveitadas para construções de ambientes em substituição dos tijolos. O objetivo deste trabalho foi estudar os aspectos necessários para a realização das obras de construção de um ambiente com materiais recicláveis analisando tipos, quantidades e custos dos materiais de construção e mão-de-obra. Além disso, criou-se estratégias para a arrecadação de garrafas pet, métodos de preenchimento das mesmas e mecanismos de divulgação do projeto intitulado ?Projeto Casa PET?. O estudo comprovou que a garrafa pet pode substituir o tijolo, que um dos materiais adequados para preenchê-las é o solo-cimento e que este tipo de construção tem despertado o interesse de pessoas de diversos locais do Brasil e até mesmo de outros países. Em futuros trabalhos, pretende-se comprovar que o ambiente é uma alternativa viável tanto do ponto de vista econômico e ambiental.

Modelagem e simulação de ciclos a gás com resfriamento de ar na entrada

The optimization of energy generation systems has become a key issue for technological and social development, mainly in developing countries, where the electricity consumption rises sharply. Gas turbine cycle is an electricity generating system, which studies have demonstrated that inlet air cooling increases net power and thermal efficiency. Thus, this study intends to quantify these parameters for environments with different ambient temperature and relative humidity. Two types of air cooling were used: evaporative and absorption systems. The configuration parameters only with the gas turbine cycle were compared to those whose configuration allowed cooling. First, it was analyzed only evaporative cooling. Next, the absorption system was used for analysis. The last configuration mixed these two methods, dividing equally its flow. The results showed that thermal efficiency and net power increase in any case of cooling, with absorption system more advantageous in terms of generated energy, where an increase between 1 and 2 MW was observed, depending on the ambient conditions . When the two methods were working together at low relative humidity, it showed a thermal efficiency increase compared to absorption system, up to 2.4%. Evaporative cooling was less effective, but it is a good and cheap possibility to increase the cycle parameters at high temperature and low relative humidity

Impactos causados por vibrações mecânicas em chapas de alumínio no processo de laminação a frio

This paper purpose is to analyze one of the main problems faced by cold rolling industry of the current time, the mechanical vibration. Factors such as strips with high velocity in order to increase the productivity and thickness becoming thinner and thinner cause the vibrations to be present at all times during rolling. These market requirements also drive the industry for technology development and thus bring the challenges that the operation of a new modern equipment and more powerful. The initial purpose is to analyze the forces that cause vibration in a rolling mill type four high with two stands, where is desirable to identify the origins of these vibrational forces to make possible dismiss them or at least control its intensity, in order to prevent damage in the rolling mill and ensure product quality to the customer. For it, will be used instruments to record and store the vibrations that occur during the lamination process. With this data will be able to analyze the characteristics of the vibrations and act at your elimination. At the end of the work is expected to demonstrate how important the critical view of the engineer in the analysis of graphics combined with the calculations of the natural vibration frequency and engagement of key parts of the laminator. With these two tools at hand, will be possible to increase the productivity of the rolling mill and act preventively in maintenance, thereby reducing your downtime and increasing its performance and efficiency
