O protetor ocular é executado em qualquer material resistente opaco, estéril ou esterelizado, como tela de algodão, película ou filme flexível plástico, ou fibra celulósica prensada, ou ainda uma conjugação desses materiais, com conformação anatômica possibilitando sua aposição superficial às órbitas oculares, adaptando-se, por meio de um recorte em sua porção mediana, à projeção do nariz. O protetor constitui de um tampão posicionado sobre as órbitas oculares, um cordão ou fita de fixação e um passante ou ranhura para a passagem do cordão de fixação.

This work deals with the thermal load study of a fictitious aircraft as well as scaling, in terms of the airflow and temperature of the air conditioning system, for heating and cooling of the its internal environment, aiming the thermal comfort of occupants. The first part is presented the techniques and methods utilized for modeling different heat exchanges that occur in the aircraft and then allowed to calculate the total heat load and the airflow and temperature necessary to comply with the requirements of the thermal comfort. Techniques to determine the basic parameters, as convection coefficient and global coefficient of heat exchange, are also presented. The work aims to develop a program, using a computational tool, to automate the calculations so that facilitate this study. It also allows to be used for other airplanes just changing parameters and the control variables related to the specific project. Finally the program performs calculations for a fictitious airplane, to analyze its functionality and the influence of parameters involved in the temperature controls. The program allowed analyzing the sensitivity of portions of the thermal load and the corresponding parameters of influence, as well as the scaling of the air conditioning in terms of airflow and temperature. It was considered, despite the simplifications, a good approximation to the actual values and then can be used in development of the other airplanes

Induction heating is a process closely linked to the concepts of heat transfer. It also covers electromagnetic induction and effect of film. Many companies use this technology in their processes due to the high accuracy that can be obtained at temperatures induced. However the dominance of this technology is not common among Brazilian industries. This involves complex systems of equation and heat exchange in transient conduction, and convection and radiation losses. With this work we seek the ability to analyze which parameters influence over this process and the order of magnitude of time required for heating a cylindrical part

This study is about a heating line that uses thermal oil. It is located in a facility that produces interlayers used in cars windshields. A plastic resin is melted and is sent to a matrix called DIE where the interlayers are produced. The DIE needs to receive heat from the circulation of thermal oil in four different regions of its interior, to ensure the correct thickness of the interlayer. The thermal energy is provided by electric heaters and the flow of thermal oil is impelled by four mechanically sealed centrifugal pumps (one per region). The key point of this study is the fact that these four pumps of the system have reported successive failures in the mechanical seals. Apparently, a poorly designed project has burdened the system intermittently. The pumps operation condition is located in a region of low efficiency, according to the characteristic curves. This fact is the source of the noticeable reduced time between failures. Changes in the configuration of the facility and in the number of pumps will be proposed, aiming to achieve higher operational efficiency. The proposals will be mathematically analyzed according to the Hydraulic Institute criteria. At the same time, we will also keep focus on an in-depth study of a heating system structure, starting with a detailed approach for each component and discussion about its real need and economic viability. At the end of this paper it is shown that the gain in efficiency achieved with the new proposed configuration reflects not only in the reduction of maintenance costs, but also a potential improvement in energy efficiency. It is shown that these two aspects are closely related and together form the basis for the design of a reliable and efficient pumping system

Considerado una verdadera lección de cine, ya que es una película que se refiere al propio arte cinematográfica, La ventana indiscreta (Rear Window), dirigida por Alfred Hitchcock en 1954, tuvo como base para el guión de John Michael Hayes el cuento “Tenía que ser un asesinato” (“It had to be murder”, 1942), de Cornell Woolrich. Reconocido como uno de los mayores escritores del género policial noir, Woolrich profesaba la “poética del fracaso, [...] conduciendo gradualmente la angustia de la víctima al centro del cuadro, en contraste con la indiferencia mecánica de una sociedad que no se molestaba con su suerte”. (OLIVA, 2003, p.116- 7). La película tuvo un gran éxito de público y crítica, pero esto no había ocurrido con el cuento, que solo se hizo conocido después de su adaptación para el cine. El propósito de este trabajo es realizar un análisis comparativo entre los dos textos, subrayando los siguientes aspectos: 1) la caracterización del género noir (cuando la investigación ya no es un juego para mentes refinadas, como había sido en la narrativa policial clásica) y del suspense (narrativa de tensión que se caracteriza por el aplazamiento de la resolución del enigma), tanto en la narración literaria como en la película; 2) la autorreferencialidad en la película y en el cuento mediante el uso de la metaficción; 3) el problema de la transposición del foco en primera persona de la narrativa para el cine; 4) los diferentes desenlaces, señalando en qué medida indican visiones del mundo también divergentes.
