This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Exploratory descriptive study, with a quantitative approach and prospective data, performed in Pronto Socorro Clóvis Sarinho (PSCS), in Natal/RN, aiming to analyze care given by the nursing and medical staff to victims of violence attended to in an emergency hospital in Natal/RN; to identify care given by the nursing and medical staff as viewed by the victims; to compare data observed during the process of care with the victim s view on the care given by the nursing and medical staff; to identify the existing knowledge on violence and the process of caring for victims and its relation with prejudice; to identify obstacles and perspectives for prevention during the process of caring for victims in the emergency services. The population consisted of 97 physicians, 16 nurses, 75 nursing technicians and assistants and 365 victims of violence, with data collected from April to May 2009. Out of 188 professionals, 52.1% are female; 32% were aged 41 to 50; 99.5% had given care to a victim of violence; 90.4% reported to have given care to patients under custody; among these, 17.3% felt prejudice; 55.3% stated they don t provide different care for assaulted victims and assailants, however 44.7% stated they do; 86.7% feel their workplace is unsafe; 61.7% denied the existence of any obstacle and 38.3% reported the existence of obstacles; among these, 26.1% referred to inadequate facilities; 37.8% believe reinforcing security and professional training are the main solutions. Among the 365 researched violence victims, 82.2% were assaulted; male (69.6%); aged 18 to 24 (24.9%); hailing from the Greater Natal area (89.9%); on 19.7% the event happened on Saturday; during the night (48.8%); victim of physical assault (61.4%); produced by body force (27.7%); 24.4% were injured in the head and neck. 57% had used some drug, among which alcohol was predominant (75.5%). On 621 observations performed during the victim care process, when compared to the report of assaulted victims, there was a statistical difference, at 5% significance level, regarding reception, resistance from the professionals, questioning about the violent event, providing of guidance, interaction with the patient and the understanding of receiving proper care, and care resolution. In comparisons involving the observed and the assailant victims reports, there was a statistical difference regarding the resence of resistance from the professionals, performance of necessary procedures and the nteraction with the patient and the understanding of receiving proper care and 58.1% reported the nursing team was the one that provided the best care. We conclude that professionals had lready given care to assailant patients, acknowledge the importance of knowing how the vent took place and acquired this preparation during their practice. The most often referred bstacles that hinder assistance were: inadequate facilities, material deficit and lack of rofessional preparation. As solutions for these problems, they cited the reinforcement of ecurity and professional training

The great importance in selecting the profile of an aircraft wing concerns the fact that its relevance in the performance thereof; influencing this displacement costs (fuel consumption, flight level, for example), the conditions of flight safety (response in critical condition) of the plane. The aim of this study was to examine the aerodynamic parameters that affect some types of wing profile, based on wind tunnel testing, to determine the aerodynamic efficiency of each one of them. We compared three types of planforms, chosen from considerations about the characteristics of the aircraft model. One of them has a common setup, and very common in laboratory classes to be a sort of standard aerodynamic, it is a symmetrical profile. The second profile shows a conFiguration of the concave-convex type, the third is also a concave-convex profile, but with different implementation of the second, and finally, the fourth airfoil profile has a plano-convex. Thus, three different categories are covered in profile, showing the main points of relevance to their employment. To perform the experiment used a wind tunnel-type open circuit, where we analyzed the pressure distribution across the surface of each profile. Possession of the drag polar of each wing profile can be, from the theoretical basis of this work, the aerodynamic characteristics relate to the expected performance of the experimental aircraft, thus creating a selection model with guaranteed performance aerodynamics. It is believed that the philosophy used in this dissertation research validates the results, resulting in an experimental alternative for reliable implementation of aerodynamic testing in models of planforms

In energy systems, the balance of entrances, exits and losses are fundamental to rationalize the energy consumption, independently of the source (sun, natural gas, wind, water, firewood or oil). This estimate is important so much in the phase of project of the facilities, as in the exploration or operation. In the project phase it indicates the energy needs of the process and the contribution of the energy in the cost of the product and the capacity of storage of the fuel and in the operation phase it allows to evaluate the use of the energy in the process of it burns, showing the weak points that should suffer intervention to improve the efficiency. With this tool, it can be implemented routines of calculation of thermal balances in ovens of it burns of structural ceramic, in way to generate an optimized mathematical model for application in the current and promising structural ceramic brazilian industry. The ceramic oven in study is located in the metropolitan area of Natal (Rio Grande do Norte) and it is a continuous oven of the type wagons tunnel, converted of firewood for natural gas and it produces blocks of red ceramic. The energy balance was applied in the oven tunnel before and after the conversion and made the comparisons of the energy efficiencies (it burns to the firewood and it burns to natural gas), what showed that the gaseous fuel is more efficient when we burn structural ceramic in ovens tunnels. When we burn natural gas, the requested energy is smaller and better used. Tests were accomplished in the burned product that showed the best quality of the burned brick with natural gas. That quality improvement makes possible to accomplish new interventions for the most rational use of the energy in the oven tunnel of the Ceramic in study and in the industries of structural ceramic of the whole Brazil, that need control tools of burning and of quality
