Programação linear no planejamento do tratamento de câncer por radiocirurgia

Medical Physics has been reaching an important role among several lines in Science, providing means for the improvement of several theories and procedures. Currently, its main application is related with the use of ionizing radiations, specially, in treatment procedures such as Radiotherapy. Radiosurgery is a Radiotherapy technique which consists in administering a single tumoricidal dose of radiation exclusively to the tumorous lesion. It becomes then an interesting alternative to surgical treatment, mainly in cerebral metastases, which are the most frequent cerebral tumors in the central nervous system. The radio neurosurgical team works out a planning for the Radiosurgery treatment, aiming for obtaining an appropriate ideal treatment for each case. For the working out of this treatment planning, Computed Tomography images of the region to be treated are obtained, digitalized and later, fused with nuclear magnetic resonance images. Through these images, critical structures, organs at risk and lesions are localized. After this, calculations are made to determine three-dimensional positions of isocenters, isodose curves, prescribed dose, collimators sizes, position, numbers and respective weight of isocentric conformal fields, and others. The treatment planning is commonly based in desired levels of dose for specific types of tumors and organs at risk concerning the irradiated region. Theses levels of dose are chosen in a way that a high probability of cure may be achieved and meanwhile, that the probability of complications, in whichever organ at risk, may be minimal. Thus, many researches have been carried out, showing that mathematical techniques may help to obtain an optimal planning for the treatment of cerebral metastases. Among the methods of optimization in the study...(Complete abstract click electronic access below)

Crescimeno de apatita na superfície da liga Ti-7, 5Mo empregando tratamento higrotérmico

The objective of the present work was to evaluate surface of experimental alloy Ti-7.5Mo after hydrothermal treatment. Ingots were obtained in arc melting furnace under an argon atmosphere and then homogenized under vacuum at 1100ºC for 86.4 ks to eliminate chemical segregation and after cold worked discs were cutting and grinding. For surface treatment, samples were immersed in a container with NaOH aqueous solution 5M, autoclaved, washed with distilled water. Followed, samples were heat treated and they were soaking in 5xSBF to form an apatite layer on the surface. Surfaces were investigated by, scanning electron microscopy, X-Rays powder diffraction, atomic force microscopy and contact angle, in order to evaluate the wettability of the alloy surface. The results were compared with our previous studies using the group of chemical surface treatments and results shows better condition is 120 minutes in the autoclave

Tratamento de efluentes provenientes de abatedouro de bovinos por meio de reator enzimático seguido de reator aeróbio operado em bateladas sequenciais

Brazil has one of the largest cattle herds in the world, so the cattle slaughter is one of the most important economic activities in the Brazilian market. But this activity requires a high demand of water, resulting in serious problems about the correct disposal of wastewater generated in the process. This effluent has a high pollution load, becoming its receiving bodies (streams and rivers) unfit for various activities such as public water supply, recreation, fisheries. To minimize the environmental impacts of its industrial wastewater and fallow the local environmental legislation, refrigerators must make the treatment of these effluents. This study aimed to verify the efficiency of a enzymatic reactor, when occur hydrolysis of lipids present in the effluent industrial of an cattle slaughter industry. The treatment system used was composed of two separate reactors: one being the anaerobic fluidized bed reactor (AFBR), inoculated with immobilized enzymes on the matrix support, and the other by sequential batch reactor (SBR) inoculated with activated sludge. Whereas, the reactors have been developed and installed at the Wastewater Treatment Laboratory, Faculdade de Ciências e Tecnologia, UNESP, campus Presidente Prudente. The procedure operating occurred differently for each reactor: preparation and inoculation of enzyme granules, filling the reactor, hydrolysis, and AFBR emptying, filling, aerobic reaction, sedimentation, and emptying the SBR. We performed three experimental stages, with the first and second stage of the work were done reactor analyzes separately, and the third step of the analysis were made with the interconnected reactors...

A pesca na Amazônia ocidental: tratamento terminológico dos termos fundamentais

Fishing is a very important activity in terms of economic and social development throughout the Amazon region. Text reading this topic revealed the presence of a terminology not yet systematized and record little research and scientific publications on the terminology of this activity. This article aims at analyzing the key terms of fishing. At first, we present a brief history of this activity in Western Amazonia, particularly in Rondônia. The theoretical support was guided by Cabré (1999), with her Communicative Theory of Terminology, Aubert (1996), Barbosa (2002), Barros (2004), Biderman (2006), Babini (2006) and linguists as Baldinger (1966) and Pottier (1974) that reveal the details of linguistic analysis terminology. The creation of an electronic corpus, from texts of technical and documental discourse, theses and websites, composed the first stage of our work. Afterwards, collect the terms and fill the terminological records in our database. The terms were organized into a conceptual system with three notional fields: riverside community, type of fishing, gillnet fishing. Early results show that the set of terms collected is characterized by the strong presence of simple and complex terms, and less compound terms.

Crescimento de apatita na superfície da liga Ti-25Ta empregando dois tipos de tratamento de superfície: biomimético e deposição de polímero por eletrofiação

Titanium and its alloys has been widely used as materials for metallic biomaterials implants are usually employed to restore the hard tissue function, being used for artificial joints and bones, synthetic plates, crowns, dental implants and screws . Objective of this work was the surface modification of Ti-alloy 25Ta from biomimetic surface treatment of employment and deposition of polymer by electrospinning. The league was obtained from the fusion of the pure elements in the arc furnace with controlled atmosphere. The ingots were subjected to heat treatment, cold forged and sectioned discs with 13 mm diameter and 3 mm thick. Two surface treatments was evaluated, biomimetic and electrospinning with PCL fiber. The biomimetic treatment was performed involving alkaline treatment for three molarities 1.5M, 3M and 5M with immersion in SBF. The electrospinning was performed using PCL polymer alloy surface after the alkali treatment Ti25Ta 1M. For this group the polymer coated surfaces were immersed in calcium phosphate containing solution for immobilization of apatite. The results were compared with previous studies using surface treatment group to verify hydroxyapatite formation on the sample surface and it is concluded that the best condition is biomimetic treatment with 5M alkali treatment and heat treatment at 80 ° C for 72 hours

Análise comparativa de três técnicas cirúrgicas como tratamento da luxação coxofemoral

A articulação coxofemoral em cães tem sido, ao longo dos anos, a mais frequentemente lesionada, principalmente de forma traumática, por acidentes automobilísticos ou atropelamentos. O tratamento de escolha para resolver a luxação coxofemoral é o método por redução fechada. Entretanto, na generalidade dos casos, esta técnica não se mostra suficiente para correta estabilização articular, pois há outras afecções envolvidas ou a cronicidade da lesão impede uma manobra efetiva. Sendo assim, recorre-se à cirurgia para correção da luxação. Diversas são as técnicas cirúrgicas praticadas para tal enfermidade. O pino transarticular é um procedimento usado há muito tempo. Essa técnica requer aceitável coaptação articular e é recomendada em casos de grave lesão capsular. Porém, seu uso é discutível por causar lesões degenerativas na articulação ou migração do implante. Dessa forma, a sutura extra-articular vem sendo estudada por apresentar uma estratégia alternativa que não prejudica as estruturas da região operada e por vir demonstrando resultados satisfatórios. Nas situações de luxação recorrente, necrose asséptica da cabeça do fêmur e fraturas de cabeça e colo femoral ou acetabular, a colocefalectomia deve ser empregada. Considerada como técnica de salvamento, esta pode ser utilizada após insucesso dos outros métodos para correção da articulação coxofemoral. Vários estudos foram selecionados para que seus resultados fossem analisados. Assim conclui-se que não existe uma técnica ideal. Todas apresentam adequada congruência articular, porém os implantes metálicos exibem grandes possibilidades de complicação pós-operatória, a sutura extra articular fornece boa estabilidade e poucas lesões locais e a colocefalectomia fica sendo como o último recurso, caso ocorra falha...
