Método de pontos interiores no planejamento ótimo do tratamento de câncer por radioterapia

The Medical Physics has been developing very fast due to the progress of the technologies and to the increase of the concerns with cure of diseases. One of the Medical Physics main performances at the present time is the use of ionizing radiations for cancer treatment, especially, services as Radiotherapy. The radiotherapy technique uses ionizing radiation with therapeutic end of cancer controls, avoiding your proliferation and it worsens of the patient. For the treatment a radiation bunch is used, with rectangular form, that it passes through the different types of tissues of the patient's body, and depending on the attenuation and of the depth of the fabrics, a great amount of energy is deposited inside in different points of the body. Like this, to plan this treatment type it should be obtained the dimension of the distribution and dose absorption along the volume. For this, it is necessary in the planning of the treatment of the cancer for radiotherapy to build isodose curves, which are lines that represent points of same amount of dose to be deposited in the area to be treated. To aid the construction of the curves of form isodose to reach the best result in the planning of the treatment, in other words, a great planning, providing the maximum of dose in the tumor and saving the healthy and critical organs, it has been using mathematical tools and computational. A plan of cancer treatment for radiotherapy is considered great when all the parameters that involve the treatment, be them physical or biological, they were investigated and adapted individually for the patient. For that, is considered the type and the location of the tumor, worrying about the elimination of the cancer without damaging the healthy tissue of the treated area, mainly the risk organs, which are in general very sensitive to the radiations. This way, the optimization techniques... (Complete abstract click electronic access below)

Sobre as considerações de uma concepção de um projeto de um forno cerâmico

The current competitiveness of the market has generated the need to minimize the cost of production companies in any field of activity, aimed at reducing the cost of production, the cost of purchasing and manufacturing processes interruption of manufacturing processes for possible maintenance. In this sense, companies are seeking methods to improve and streamline their production line. In ceramics industries, cooking the pieces is the portion of the production process that influences the total costs. The oven construction and maintenance represent a large portion embedded in the cost of the final ceramic product. The proposal for a type of oven for baking the parts that takes into account a better burning process, knowledge of the causes of disease and cost analysis of purchasing both of the constituent materials and labor for its construction, can be significant importance to the composition of final product costs or time analysis of ROI. It is proposed a streamlined design of an oven that takes into account the positive characteristics of the furnaces already built and that the experience has endorsed, and also others that are added at the end, lead to a reduction in production cost, the cost income and the number of pathologies arising from wear of the furnace along the lifespan. Therefore, according to the experiences gained over the years in the construction of furnaces and experience of manufacturing of ceramic, it is proposed a project that has an oven improvement over those now being built and that include, among other topics, economy in fuel burning, streamlining the building process

Análise preliminar para a estimativa da perda de calor sensível de um fluido homogêneo térmico em um reservatório de geometria cilindrica

This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating

Desenvolvimento de vasos digestores de amostra para microondas doméstico

The application of microwave radiation on the sample preparation has been expanding increasingly in areas involving decomposition by wet and dry roads, fusion, extraction, acceleration of chemical reactions, for example. Currently, the use of microwave ovens for analytical purposes are recognized for having excellent performance for organic and inorganic samples. In the international market there are several kinds of microwaves oven which adapt the varied purposes, however yet with elevated prices which incapacitate your use as routine equipment in laboratory. Thus, many researchers have been choosing for developing own projects of microwaves oven production or to use domestic oven for the laboratory, with or without adaptations. For the evaluation of the proposed method was used in the Kjeldahl methodology for determining total nitrogen in samples of crude protein, using a domestic microwave oven and a digester pot made up in TeflonTM and distillation by steam. Were made to adapt and characterization of a domestic microwave oven, the confeccion vessel digester and the metal support for the vessel. The accuracy of the proposed method was confirmed by comparison of two methods, the standard method for conventional heating and by the proposed method, with heating by microwave radiation through the calculated values of relative standard deviation analysis

Estudo da dispersão pós-alimentar em larvas de moscas-varejeiras via autômatos celulares

In this paper, a computational analysis, using a cellular automata model, has been developed to analyze post-feeding dispersal behavior of blow y larvae. This model aimed to: simulate the exponential decline of pupal number in relation to the feed source and spatial oscillation due to larval interaction during dispersal; study whether the prior pupal presence in uences distribution patterns of larval frequency; and compare obtained unidirectional dispersal patterns to the cross-dimensional ones. The cellular automata (CA) model was able to successfully reproduce the essential features of the larval dispersal process and, thus, show the importance of local interaction in the studied dispersal process dynamics. Oscillations could be explained by the interaction among dispersing larvae and intrinsic pupation time. The box size and the initial larval density were important factors for the experiment because they in uenced the results. Results showed that the unidirectional dispersal could be used to simulate the larval dispersion that occurs in the natural environment, because both models had a similar result. These results are important to understand how di erent factors can in uence the dynamics of blow y larval dispersal, bringing important results for behavioral ecology and forensic entomology

O desenvolvimento de habilidades argumentativas no ensino médio: perspectiva a partir de um minicurso investigativo com base na história da ciência

The performance of investigative activities with lessons in teaching Science and Chemistry has promoted meaningful learning of scientific knowledge. This study aimed to develop the links between higher education for research and skills argumentative, aimed at building the scientific concept on combustion of the candle in a closed container, for students from two classes of 3rd year of high school, two city schools Bauru, São Paulo. We decided to do a short course investigative, to respond argumentative skills which are developed during the minicourse using investigative activities, knowledge from the history and philosophy of science. The results were gathered from analysis of video recordings of episodes of the short course in both the groups, to produce a higher rate of use of argumentative skill, which were classified into categories according to the prior knowledge of the subject, 'factual knowledge' , 'understanding of concepts' and 'reasoning and analysis.' From the information obtained, it was found that both the teachers and the students were consistent in their actions, and that the activity of reasoning is key to learning. Thus, one can realize that knowledge is not acquired all at the same time, each individual depends on the mediation of the teacher in order to reach different design more appropriate teaching and investigative linked with the argument can be the key tool to acquire this knowledge
