Aplicações práticas de proteção radiológica nas áreas de medicina nuclear e radiodiagnóstico em instalações hospitalares

After the discovery of ionizing radiation, its applications in various fields of science began to take significant proportions. In the case of medicine, there are the application areas in radiotherapy, diagnostic radiology and nuclear medicine. It was then necessary to create the field of radiological protection to establish the conditions necessary for the safe use of such ionizing radiation. Apply knowledge obtained during the graduation stage and in the practice of radiological protection in the areas of nuclear medicine and diagnostic radiology. In the area of nuclear medicine, tests were made in the Geiger-Muller counters (GM) and the dose calibrator (curiometer), the monitoring tests of radiation, waste management, clean of the Therapeutic room and testing the quality control of gamma-chambers. In the area of radiology, were performed tests of quality control equipment for conventional X-ray equipment and x-ray fluoroscopy, all following the rules of the National Health Surveillance Agency (ANVISA), and reporting of tests. The routine developed in the fields of nuclear medicine in hospitals has proved very useful, since the quality control of GM counters contribute to the values of possible contamination are more reliable. The control of dose calibrator enables the patient not to receive different doses of the recommended amounts, which prevents the repetition of tests and unnecessary exposure to radiation. The management of waste following the rules and laws established and required for its management. Tests for quality control of gamma chambers help to evaluate its medical performance through image. In part of diagnostic radiology, tests for quality control are performed in order to verify that the equipment is acceptable for usage or if repairs are needed. The knowledge acquired at the internship consolidated the learning of graduation course

Identificação e avaliação da resistência antimicrobiana de leveduras em vegetais minimamente processados

The consumption of minimally processed vegetables has been growing due to consumer demand for products easy to prepare. As it is extremely manipulated, this product can be contaminated with spoilage organisms such as yeasts, that have the ability to decrease the shelf life of food. In this sense, seeking to concerns about the resistance of microorganisms to sanitation methods for food industries and given the need for more studies of the antimicrobial power of ozone, this study aimed to isolate and identify the yeasts present in minimally processed vegetables, and check their antimicrobial resistance to sodium hypochlorite and ozone. 84 samples of minimally processed vegetables were collected. From them, 47 yeast cultures were isolated and submitted for identification and testing of resistance to sodium hypochlorite sanitizers (50, 100, 200 and 400 ppm) and ozone (0.25 and 0.5 ppm). From the total yeast isolated, 85.1% corresponds to Cryptococcus laurentii, 12.8% to Arxula adeninivorans and 2.1% to Debaryomyces hansenii var. fabryii. All of them were resistant to the sanitizers sodium hypochlorite and ozone at all concentrations tested. Given these observations, some actions must be taken during processing to avoid contamination with deteriorative microbiota.

Estudo da fadiga em liga de alumínio aeronáutico 7475-T761

This work will address the study of fatigue conditions with constant load in an alloy of aluminum analysis 7475 - T761, so we can better understand the conditions of the aircrafts which contain this alloy in their structures. A literature review, which was discussed the concepts of fracture mechanics, fatigue, aeronautical components, chemical analysis of aluminum alloys, fatigue problems that appears in the aircrafts, metallographic analysis, and testing of optical microscopy tensile, fatigue and microhardness, surface analysis (MEV) study of the chemical composition of the alloy in question, the main causes of crashes, was performed, completing the work, analysis of data from tensile test, hardness and fatigue together with the interpretation of images of optical microscopy and scanning electron was taken. The data indicated the high mechanical strength of the alloy, along with its microstructure indicating elongated grains and high surface contour, which shows such resistance by hindering the movement of dislocations. The grooves are clearly shown in the MEV images as well as the classic with increased fatigue loading and subsequent reduction of the number of cycles to rupture behavior shown in the graphs. Therefore we observed the optimal behavior is supported by the league when subjected to fatigue loadings

A correspondência de Cláudio Manuel da Costa dirigida aos acadêmicos renascidos: informes de uma sociedade letrada

In this article we intend to discuss the type of letters produced by Cláudio Manuel da Costa when he was member of Academia Brasílica dos Renascidos basing the analyses on the ancient rhetoric, used as a model by scholars between sixteenth and eighteenth century. These documents show his filiation with academicism practices, presents evidence of his biography and his domain of two writing styles: the poetic style for which he is known, and the academic style, employed in the exercise of his function under the literate associations, confirming his actions, both in the political and intellectual framework of that time.

Victor Hugo: sobretudo, poeta

Victor Hugo was one of the most important writers of the French litterature. He publishied novels and plays, but he dedicated himself especially to the poetry. This article aims to describe the poetic journey of Victor Hugo and analyses how the History of France, the life of the writer and the discussions about Romantism combined and formed a work that traverses the century.

GeoGebra e o método de Briot & Bouquet para a resolução gráfica de equações cúbicas

In the mid-nineteenth century, french mathematicians Briot and Bouquet have proposed an intriguing graphical method for solving cubic equations "depressed" - the third degree equations that do not have the quadratic term. The proposal is simple geometric construction, though based on an ingenious algebra. We propose here the verification and testing graphical method through an instructional sequence using the software GeoGebra also present the ingenious algebraic development that resulted in this graphic method for determination of real roots of a cubic equation of the type x³ + px + q = 0 where p and q are real numbers. The method states that these solutions are summarized in the abscissas of the points of intersection of the circumference containing the origin and the center C (-q/2, 1-p/2) with the parable y = x².
