Texto completoThe number of sweet orange cultivars used in commercial orchards in Brazil is restricted, although the diversity of genera, species, cultivars and clones of citrus is great. However, the industrial processing is based on four main cultivars, the \'Hamlin\', as early maturing, the \'Pera\', as mid-season, and \'Natal\' and \'Valencia\' as late maturing cultivars. Anchored on these four cultivars, the orange juice industry processes fruits from June through December with greater intensity, January and February with lower supply, and the period from March through May is considered off season. Therefore, it is extremely important to select varieties that produce during this period. The objective of this study was to evaluate the horticultural performance of twelve early maturing sweet orange cultivars and identify those better than the \'Hamlin\' sweet orange, aiming to offer new options for producing fruits with quality, as for fresh fruit market as for industrial utilization, during early citrus harvest season in the southwest region of São Paulo state. The cultivars \'Hamlin\' (early maturing standard cultivar), \'Westin\', \'Pineapple\', \'Ruby\', \'Seleta Vermelha\', \'Mayorca\', \'Valencia 2\', \'Oliverlands\', \'Kawatta\', \'IAPAR 73\', \'Salustiana\' and \'Valencia Americana\' were evaluated. The experimental design was completely randomized with four replications, consisting of three plants of each cultivar per plot. Data concerning vegetative growth (plant height, stem diameter and canopy volume), production and yield efficiency, fruit morphology (mass, width, length, size, shell thickness and number of seeds) and the characteristics of internal fruit quality (total soluble solids, acidity, percentage of juice, \"ratio\", technological index, ascorbic acid, color indexes of pulp and peel) were collected The averages were compared to \'Hamlin\' sweet orange (standard cultivar) and analyzed by Dunnett test. To evaluate the characteristics simultaneously, performance indexes were estimated for identifying promising cultivars for utilization as for juice industry as for consumption fresh fruit market. \'Oliverlands\' was the sweet orange cultivar which showed higher plant height and plant volume, higher production and yield efficiency as compared to \'Hamlin\' sweet orange. The cultivar \'Westin\' showed higher performance index for the industrialization process, whereas \'Valencia 2\' and \'Salustiana\' sweet oranges had adequate performance indexes for fresh fruit market. There was no cultivar of sweet orange that had the simultaneous ability for the juice industry and for fresh fruit market in the southwestern region of Sao Paulo state.

Texto completoOs avanços tecnológicos na área da geração de imagens médicas com radiações ionizantes possibilitaram a realização de intervenções invasivas que têm beneficiado diversas áreas da medicina, destacando-se entre essas as intervenções em cardiologia intervencionista. Apesar dos benefícios, os procedimentos intervencionistas geralmente envolvem o uso de longos tempos de exposição à radiação e representam, para pacientes e trabalhadores, um risco maior do que o de outros procedimentos nos quais também há exposição à radiação. Este trabalho apresenta os resultados da dosimetria realizada em médicos e pacientes (pediátricos e adultos) durante intervenções cardíacas percutâneas e procedimentos de diagnóstico, realizados no período de abril de 2007 a agosto de 2010, em um hospital de referência na cidade de Recife, Pernambuco. As medidas dosimétricas foram tomadas em 143 procedimentos, dos quais 118 foram realizados em pacientes adultos e 25 em pacientes pediátricos, estes com doença cardíaca congênita. Os procedimentos foram realizados por meio de um angiógrafo monoplanar Philips (modelo Allura 12), equipado com intensificador de imagem. A dosimetria de pacientes foi realizada pelo emprego de filmes radiocrômicos e de parâmetros de indicação de dose apresentados pelo equipamento angiográfico; e para a dosimetria nos médicos se utilizaram dosímetros termoluminescentes distribuídos no corpo e nas vestimentas de proteção dos profissionais. Durante os procedimentos clínicos, foram registrados parâmetros de irradiação e informações como: número de imagens, tempo acumulado em fluoroscopia; magnitude do kerma ar cumulativo no ponto de referência IRP [Ka,r], entre outras. Os resultados da dosimetria de pacientes mostraram valores de kerma ar na superfície de entrada da pele do paciente [Ka,e], variando de 240 a 5.897 mGy, nos pacientes adultos, e de 45 a 1.079 mGy nos pacientes pediátricos. A máxima dose absorvida na superfície (MDA) da pele do paciente variou de 649 a 4.180 mGy, nos pacientes adultos, e de 214 a 487 mGy, nos pacientes pediátricos. Seguindo orientações de guias de acompanhamento de pacientes, os pacientes que apresentaram MDA maior que 3 Gy ou Ka,r maior que 5 Gy foram avaliados, pelos médicos, após 14 dias do procedimento e não se observou a ocorrência de lesões. Com relação aos médicos, a dose efetiva média por procedimento foi 5,2 μSv em procedimentos de diagnóstico com pacientes adultos e de 4,5 μSv com pacientes pediátricos. Nos procedimentos de intervenção, os valores foram 10,8 μSv e 6,4 μSv, em procedimentos com pacientes adultos e pediátricos, respectivamente. Os valores de dose equivalente por procedimento, mais altos, medidos no corpo dos médicos, foram: 922 μSv no pé esquerdo, 514 μSv no pé direito, 382 μSv nas mãos e 150 μSv nos olhos, em procedimentos com pacientes adultos. Com pacientes pediátricos, os valores foram: 123, 127, 1.188 e 224 μSv, respectivamente. A ausência de acessórios de proteção (tela e saiote pumblíferos) e EPIs específicos (óculos e luvas) são explicações para os valores altos registrados. Dependendo do número de procedimentos, as doses recebidas pelos médicos podem exceder os limites de dose anual (150 mSv para o cristalino dos olhos e 500 mSv para extremidades) estabelecidos por normas nacionais e internacionais

Texto completoIn this work, we evaluated the dosimetric characteristics of a shielded rectal applicator with an endocavitary balloon injected with contrast solution. The dose distributions around this applicator were calculated by the GEANT4 Monte Carlo (MC) code and measured by ionization chamber and GAFCHROMIC EBT film. A patient-specific dose calculation study was then carried out for 40 rectal treatment plans. The PTRAN_CT MC code was used to calculate the dose based on computed tomography (CT) images. This study involved the development of BrachyGUI, an integrated treatment planning tool that can process DICOM-RT data and create PTRAN_CT input initialization files. BrachyGUI also comes with dose calculation and evaluation capabilities.
We proposed a novel scatter correction method to account for the reduction in backscatter radiation near tissue-air interfaces. The first step requires calculating the doses contributed by primary and scattered photons separately, assuming a full scatter environment. The scatter dose in the patient is subsequently adjusted using a factor derived by MC calculations, which depends on the distances between the point of interest, the iridium source, and the body contour. The method was validated for multicatheter breast brachytherapy, in which the target and skin doses for 18 patient plans agreed with PTRAN_CT calculations better than 1%.
Finally, we developed a CT-based analytical dose calculation method. It corrects for the photon attenuation and scatter based upon the radiological paths determined by ray tracing. The scatter dose is again adjusted using our scatter correction technique. The algorithm was tested using phantoms and actual patient plans for head-and-neck, esophagus, and MammoSite breast brachytherapy. Although the method fails to correct for the changes in lateral scatter introduced by inhomogeneities, it is a major improvement over TG-43 and is sufficiently fast for clinical use.
En curiethérapies à haut débit de dose, la dose aux patients est évaluée selon le protocole AAPM Task-Group 43 (TG43), qui utilise des paramètres dosimétriques obtenues avec une source dans l'eau. Cependant, le patient, l'applicateur et le contraste ont des propriétés radiologiques différentes de l'eau; ces inhomogénéités sont donc négligées dans TG43.
Dans ce travail, nous utilisons le programme Monte Carlo (MC) GEANT4 pour évaluer les propriétés dosimétriques d'un applicateur rectal muni d'un blindage radio-protecteur et d'un ballon intra-cavitaire. Ces résultats sont confirmés par des mesures d'une chambre d'ionisation et des films GAFCHROMIC EBT. Une étude des calculs de dose a été faite avec le programme PTRAN_CT avec l'aide des images scanner de 40 patients de cancer rectal. Ceci a conduit au développement de BrachyGUI, un programme de planification de curiethérapie, capable de traiter les données DICOM-RT des patients et générer les paramètres d'entrée pour PTRAN_CT. BrachyGUI dispose d'outils de calcul, d'extraction et d'analyse de dose.
Nous proposons une nouvelle méthode de calcul qui tient compte des effets de diffusion au voisinage des interfaces tissus-air. Cette méthode calcule séparément la dose due aux photons primaires et diffusés, ensuite la composante diffusée est ajustée par un paramètre extrait des calculs MC incluant les contours du patient, la source et sa position. Nos résultats s'accordent avec une incertitude inferieure à 1% avec les calculs de dose à la surface et dans la cible effectués avec PTRAN_CT pour 18 patients en curiethérapie du sein.
Enfin, nous avons conçu une méthode analytique de calcul de dose qui incorpore l'atténuation et la diffusion des photons, et qui est basée sur les chemins radiologiques déterminées par traçage des trajectoires. Cet algorithme est validé par l'utilisation de fantômes, des données de patients traités pour divers cancers (oesophage, tête et cou), et par la curiethérapie MammoSite du sein. Bien que cette méthode ne reproduise pas bien les diffusions latérales induites par les inhomogénéités, elle représente une amélioration majeure par-rapport-à TG43 et est rapide pour une implémentation clinique.

Texto completoEsta propuesta visual nace desde la dísciplina de la cerámica y se centra en su significado místico; la transformación de los elementos, hecho que ha sido considerado sagrado desde los albores de esta práctica y con mucha mayor profundidad en el chamanismo y la alquimia. Tanto así que estos últimos, tienen la creencia de que todo nace y viene de una sola fuerza. Con este planteamiento calzo mi propuesta; que está ligada a la muerte y a la problemática existencialista, lo que se expresa en los ritos funerarios y los residuos corporales, ambos como respuesta a una necesidad del ser humano por conservar parte de la vida, para recordar y ser recordados. De este modo, acudo a la urna fúnebre (vasija de cerámica contenedora involutiva del difunto y también parte de su ajuar), como base para plantear cuestionamientos en torno a la disciplina. La urna en sí pasa a segundo plano y deja hablar a la materialidad cerámica, las tierras y los residuos corporales (pelo, dientes uñas y huesos), expuestos al interior de frascos de vidrio que se entrelazan con las nebulosas de estrellas, ya que comparten los mismos químicos en su composición. Desde hace unos años, los científicos vienen planteando una relación directa entre los compuestos presentes en la tierra y en el medio extraterrestre. Mi propuesta plástica es: La instalación de 26 frascos de vidrio dentro de cajas de madera donde 13 de ellos tendrán en su interior; cabello, uñas, dientes y un hueso humano, los frascos restantes contendrán diferentes componentes de la tierra, que conforman como explicaba anteriormente, parte de nuestro cuerpo y el de las estrellas. Refuerzo esta idea con la disposición de siete cajas y empleando vidrio post formado coloreados con pigmentos de sobrecubierta para vidrio, con imágenes que simulan nebulosas junto con huesos modelados en forma directa en material cerámico.

Texto completoMålet med detta projekt är att utveckla en applikation med syfte att hjälpa studenter prokrastinera mindre och planera sina studier. Att distraheras av mobiltelefonen är ett vanligt problem bland studenter idag och många ser prokrastineringen med en mobiltelefon som ett allvarligt bekymmer. Applikationens syfte är att motverka prokrastinering och stress genom att stänga av distraherande appar under en studiesession och erbjuda användaren att planera in arbeten och examinationer. Applikationen HappyHelper erbjuder användaren att under en tidsinställd period blockera distraherande applikationer och en kalenderfunktion för att planera in sina studier; projektet uppnår därmed sitt mål. För att avgöra huruvida syftet är uppfyllt eller inte, krävs en användarundersökning som är planerad att genomföras in en snar framtid.

Texto completoThe increasing utilization of PET packaging in the last years in Brazil has concerned oil producers regarding oxidation. In this work, corn and canola oils, free from antioxidants and citric acid, were added of different TBHQ concentrations, and submited to accelerated (thermo and light induced) oxidation in a Schaal oven test at 63 0 C for 120 hours and in a photooxidation chamber for 168 hours. Peroxide and absorbance values at 232 nm and 270 nm were analysed in these oils. From the Schaal oven test, oil peroxide values were plotted against TBHQ concentrations and the best and the economical doses were determinated to be 119 mg/kg and 115 mg/kg TBHQ, respectively, for corn oil and 116 mg/kg and 108 mg/kg TBHQ, respectively, for canola oil. A shelf life test in PET flasks was conducted using 115 mg/kg TBHQ, for corn oil, and 108 mg/kg TBHQ, for canola oil, values that are lower than the maximum allowed by legislation and both oils were kept for 6 months.

Texto completoBefore supplying lots of components for the manufacture of orbital systems, large space agencies (CNES, ESA, NASA, JAXA ...) and the Industrial Space (EADS, Thales, ...) should ensure the reliability lots offered by manufacturers of integrated circuits. In order to ensure reliability of components, tests are performed following recommendations to select and sort the components according to their resistance to different failure modes. Of all these tests, some are typical for space applications: tests held in the dose. The specificity of the tests held at the dose of components for space applications due to the fact that the environment is a space radiation environment which causes ionization in the materials of the satellite. Following this ionization charges are created in the material and induce changes in the materials that comprise integrated circuits, which can cause drift of their electrical characteristics. These abuses of the electrical parameters in a space environment can be viewed as accelerated aging of electronic components, and tests are dedicated to predict and verify the correct operation of the components even after the accelerated aging caused by dose. In this thesis we investigate the applicability of a technique for accelerated testing of components developed in bipolar UM2: 'The technique of Switched Flows'. A study of the effect of the polarization during irradiation was conducted during this thesis, to understand the impact of the polarization of the bipolar components on the estimates obtained in an accelerated manner using this technique

Texto completoThis thesis concerns the compensation of the anatomical variations, mainly the organs at risk (rectum, bladder) deformations, which occur during intensity modulated radiotherapy of the prostate cancer. These variations can lead to significant dose drift compared to the initially planned dose, increasing the risk of toxicity. Thanks to the evolution of imaging devices and of image processing methods, dose accumulation processes, allowing to estimate the cumulated dose during the treatment, have been recently proposed. Nevertheless those strategies suffer of a lack of evaluation and their integration into an adaptive radiotherapy raises many questions. Thus, in the first part of this work, a dose accumulation method recently developed at the LTSI was evaluated using a numerical phantom. The results obtained showed that the dosimetric uncertainties related to the cumulated dose process remain low compared to the dose drifts observed for patients. The second part of this work aimed to develop a dose guided adaptive radiotherapy process and to evaluate its dosimetrical benefit using three patients showing a dose drift. The principle of this method is to detect a potential drift between the planned and actually delivered doses and, if necessary, to compensate them thanks to one or more replanning(s). The results have shown that this approach has reduced the dose drift to the organs at risk, while increasing the dose to the prostate compared to standard IGRT treatment, with a limited number of replannings (one or two), enabling to consider a clinical implementation

Texto completoResumo: A tomografia computadorizada (TC) é amplamente utilizada no diagnóstico e estadiamento de patologias da região de abdômen-pelve devido a sua alta sensibilidade e especificidade. A possibilidade de adquirir maior número de imagens em menor tempo e a maior disponibilidade de equipamentos levaram a um aumento significativo dos exames de TC e consequente aumento das doses efetivas globais fornecidas por esta modalidade. Desta forma, foram desenvolvidas ferramentas que buscam reduzir as doses de radiação dos exames sem perda da qualidade da imagem. Uma destas ferramentas é a modulação automática da corrente do tubo (automatic tube current modulation – ATCM), que permite a obtenção de exames que concordam com o princípio ALARA (as low as reasonably achievable). O objetivo deste estudo foi avaliar a qualidade da imagem e as doses de radiação de diferentes protocolos de TC de abdômen-pelve com a ferramenta ATCM. Foram avaliados cinco protocolos de TC de abdômen-pelve com a ferramenta ATCM em dois tomógrafos distintos, um 16-canais e um 64 canais. Foi utilizado um fantoma antropomórfico para avaliações dosimétricas e um fantoma analítico para avaliações objetivas de qualidade da imagem. Para a análise subjetiva da qualidade da imagem, foram utilizados 15 exames retrospectivos de pacientes submetidos a TC de abdômen-pelve. Estes exames foram avaliados por um radiologista com experiência na área de tomografia de abdômen. As três análises forneceram informações que possibilitaram a escol...

Resumo: Esta pesquisa teve por objetivo explicitar o papel do espetáculo didático musical Doce Flauta Doce em atividades de apreciação musical do público infantil em ambiente escolar. Foi realizado um diagnóstico prévio do público infantil participante da pesquisa; analisou-se a influência desse espetáculo sobre o interesse das crianças em tocar um instrumento musical, bem como suas impressões e participações diante do espetáculo; e foram especuladas as possibilidades de aprendizagem musical decorrentes do espetáculo. No primeiro capítulo é apresentado o concerto didático como uma forma de ensino musical informal e exemplos de projetos estruturados envolvendo este tema. No capítulo seguinte apresentam-se reflexões de educadores musicais sobre a apreciação musical e sua função no ensino musical. A metodologia adotada foi estudo de caso, que incluiu duas apresentações do espetáculo didático musical Doce Flauta Doce, no ano de 2015, em uma escola pública do município de Curitiba. O instrumento de pesquisa adotado consiste em questionários com três categorias de público participantes desta experiência: as crianças, os professores e os músicos envolvidos, e, complementarmente, em desenhos elaborados pelas crianças após o espetáculo. Pôde-se concluir que as crianças, por meio do espetáculo, entraram em contato com a diversidade de instrumentos, puderam compará-los, analisá-los, e também conhecer como funcionam. Além disso, percebeu-se que quando solicitadas a participar da performance, o grau de engajamento e atenção aumenta consideravelmente. Com esta pesquisa constata-se que o espetáculo didático musical Doce Flauta Doce, por meio da apreciação musical ao vivo, propiciou a aproximação das crianças à música instrumental, com liberdade expressiva, despertando nelas a curiosidade pelo diferente (independente de seu gosto musical), e proporcionando autonomia para que pudessem realizar as suas próprias conexões entre o que viram e escutaram, e suas próprias experiências com a música. Palavras-chave: Flauta doce. Espetáculo didático musical. Apreciação musical. Ambiente escolar.
Abstract: This research aimed to explain the role of the didactic musical spectacle Doce Flauta Doce on music listening of children's audience in the school environment. First, it was made a previous diagnosis of the child audience participant of the research. Then, the influence of this spectacle on children's interest in playing a musical instrument was analyzed, as well as their impressions of the spectacle, and their participation in it. The possibilities of musical learning resulting from the spectacle were speculated. The first chapter presents the didactic concert as a form of informal music teaching and also some examples of structured projects involving this subject. The next chapter presents some reflections of music educators on music listening and their role in music teaching. The methodology used was case study, which included two performances of the didactic musical spectacle Doce Flauta Doce, in 2015, in a public school in the city of Curitiba. The research instrument adopted consisted of questionnaires applied to three categories of people that participated in this experience: children, teachers and musicians. Additionally, the research instrument consisted also of drawings produced by the children after the spectacle. It was possible to conclude that children, thanks to the spectacle, came into contact with the diversity of instruments, could compare them, analyze them, and also know how they work. Moreover, it was noticed that when asked to participate in the performance, the degree of engagement and attention has increased considerably. As a result of this research it appears that the didactic musical spectacle Doce Flauta Doce, through the live music listening, propitiated the approximation of children to the instrumental music, with expressive liberty, awakening in them the curiosity about the unknown (regardless of their musical tastes), and providing them autonomy to make their own connections between what they saw and listened and their own experience with music.

Texto completoThis study investigates the potential for hydrothermal alteration and circulation in lava domes using combined analytical, remote sensing and numerical modeling approaches. This has been accomplished in three parts: 1) A comprehensive field, geochemical and remote sensing investigation was undertaken of the hydrothermal system in the Santiaguito lava dome complex in Guatemala. The Santiaguito domes were found to contain mainly hydrous silica alteration, which is unlikely to weaken dome rock, but the summit of Santa Maria was found to contain pervasive argillic alteration (clay minerals), which do pose more of a collapse-related hazard. These results were confirmed by hot spring geochemistry which indicated that water in the domes was responsible for some rock dissolution but had a residence time too short to allow for secondary mineralization. 2) A finite element numerical modeling approach was developed which was designed to simulate the percolation of meteoric water in two dome geometries (crater-confined and 'perched'), and the results were compared to the surface expression of hydrothermal systems on existing lava domes. In both cases, we concluded that simulated domes which lacked a high-temperature (magmatic) heat source could not develop a convecting hydrothermal system and were dominated by gravitational water flow. In these low-temperature simulations, warm springs (warmer high fluid fluxes) were produced at the base of the dome talus and cool springs were dispersed lower down the slope/substrate; fumaroles (high vapor fluxes) were confined to the dome summits. Comparison with existing dome cross sections indicates that the simulations were accurate in predicting fumarole locations and somewhat accurate at predicting spring locations, suggesting that springs may be subject to permeability contrasts created by more complicated structural features than were simulated in this study. 3) The results of the numerical modeling were used to calculate alteration potential in the simulated domes, indicating the most likely areas where alteration processes might either reduce the strength of a dome or reduce permeability that could contribute to internal pressurization. Rock alteration potential in low-temperature lava domes was found to be controlled by material permeability and the presence or absence of a sustained heat source driving hydrothermal circulation. High RAI values were preserved longer in low-permeability domes, but were more strongly developed in domes with higher permeabilities. Potential for mineral dissolution was highest at the base of the dome core, while the potential for mineral precipitation is highest at the dome core-talus interface. If precipitated minerals are impermeable, the dome core/talus interface would be a likely location for accumulation of gases and initiation of gas-pressurization-related collapse; if alteration is depositing weak (i.e. clay) minerals in this area, the dome core/talus interface might be a candidate for collapses occurring as the result of alteration processes.
The results of this study are all geared toward answering two broad questions: Where are hydrothermal alteration processes likely to occur or be focused within lava domes? and What effect could these processes have on dome stability? In the specific case of the Santiaguito dome complex, the combination of a quickly-recharged, low-temperature hydrothermal system in the inactive domes actually indicated a low possibility of collapse related to alteration minerals. This result was reinforced by the results of the numerical modeling, which indicated that domes are unlikely to develop sustained hydrothermal convection without the presence of a significant (magmatic) heat source and—in the case of Santiaguito—are likely to produce more hydrous silica alteration minerals when they also lack a source of acidic gases. Models of alteration potential do detail, however, that both shallow and deep dome collapses are still a possibility with a low-temperature hydrothermal system, given either a) a source of acidic gases to drive the formation of clay minerals (which are most likely to be deposited at the core/talus interface of a dome, or b) enough deposition of silica minerals in pore spaces to lower permeability in dome rock and promote internal gas pressurization. The results of this study are not limited to lava domes, as the volcanic edifices on which they rest are composed of the same materials that comprise lava domes and are therefore susceptible to the same hydrothermal processes. Further simulations of both lava domes and their associated edifices, including mineral species models, could help constrain under what conditions a lava dome or volcano is likely to develop areas of weak mineral precipitates (such as clay minerals) which could provide sites for collapse, or develop an impermeable cap of silicate minerals which could trap rising vapor and contribute to the pressurization of the edifice in question (which can in turn lead to collapse).

Texto completoThis thesis aims at the dosimetry of high energy photon beams delivered to the patient during an external radiation therapy treatment. The objective of this work is to use EPID the Electronic Portal Imaging Device (EPID) in order to verify that the 3D absorbed dose distribution in the patient is consistent with the calculation performed on the Treatment Planning System (TPS). The acquisition is carried out in continuous mode with the aS-1200 amorphous silicon detector embedded on the TrueBeam STx machine (VARIAN Medical system, Palo Alto, USA) for 10MV photons with a 600 UM.min-1 dose rate. The source-detector distance (SDD) is 150 cm. After correction of the defective pixels, a calibration step is performed to convert the signal into an absorbed dose in water via a response function. Correction kernels are also used to take into account the difference in materials between EPID and water and to correct penumbra. A first model of backprojection was performed to reconstruct the absorbed dose distribution in a homogeneous medium by taking into account several phenomena: the scattered photons coming from the phantom to the EPID, the attenuation of the beams, the diffusion into the phantom, the build-up, and the effect of beam hardening with depth. The reconstructed dose is compared to the one calculated by the TPS with global gamma analysis (3% as the maximum dose difference criteria and 3mm as the distance to agreement criteria). The algorithm was tested on a homogeneous cylindrical phantom and a pelvis phantom for Intensity-Modulated Radiation Therapy (IMRT) and (Volumetric Arc Therapy (VMAT) technics. The model was then refined to take into account the heterogeneities in the medium by using radiological distances in a new dosimetrical approach better known as "in aqua vivo" (1). It has been tested on a thorax phantom and, in vivo on 10 patients treated for a prostate tumor from VMAT fields. Finally, the in aqua model was tested on the thorax phantom before and after making some modifications to evaluate the possibility of detecting errors that could affect the correct delivery of the dose to the patient.

The present work was undertaken at the Department of Chemistry and Biochemistry of the Instituto de Biociências, at the Universidade Estadual Paulista, Botucatu Campus. The objective was to evaluate the development of the sweet potato (Ipomoea batatas L.) in a starch-modified culture and verify the possibility of the substitution of the agar agent for starch in the micro propagation of the sweet potato.

Texto completoThe receptors of digital radiography image are gradually substituting the screen-film systems in radiodiagnostic. Currently, computed radiography is the most common method in many radiography services. It is based in the application of photostimulable phosphorus, that are also known as phosphorus storage. When screen-film systems are utilized as image receptors, an inadvertently high dose of radiation in the patient will result in a dark film screen, that inputs immediate feedback to the radiology technician as to the technical factors utilized and the relative dose. However, when digital image receptors are used, a high dose in the patient can produce excelent images which re-sult in a tendency of using higher doses than necessary. The adequate extenuation and optimization of the procedures demand the knowledge of the characteristic dose values in patients in a determined radiodiagnostic service. The term exposure index refers to the absorbed dose in the phosphorus plate. Following the image reading with a laser system the histogram of signs is computed and the exposure index is determi-ned in the basis of picture elements using a logarithmic relationship. The manufacturer of the systems of pixels offer the exposure indexes as a safeguard against high doses, but the basis for the recommended values are not clear. Moreover, the exposure indexes are not directly related to the dose in patients. The aim of this work was to establish an indirect method to estimate the values of entrance doses in patients who have undergone diagnostic exams in X ray systems with computed radiography based on exposure indexes. The values of entrance doses obtained were compared with the values also obtained indirectly based in the measurements of the X ray tubes output.

Texto completoThe purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in São Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years.

Texto completoDentre os procedimentos especiais de fluoroscopia destacam-se a histerossalpingografia (HSG) e a dacriocistografia (DCG). A HSG é uma técnica radiodiagnostica capaz de detectar patologias uterinas e tubárias, e é fundamental para a investigação de infertilidade. A DCG trata-se do exame radiográfico do sistema lacrimal, sendo importante para mostrar o nível de obstrução, a presença de dilatação do saco lacrimal, bem como alterações em estruturas vizinhas. Neste trabalho, foi efetuado o estudo da dose de entrada na pele do paciente devido a estes dois procedimentos especiais de fluoroscopia, bem como a avaliação da dose na equipe médica que executa os exames. Para tanto, foram avaliados os procedimentos de 22 pacientes de HSG e 8 pacientes de DCG. Dosímetros de TLD-100 foram utilizados e fixados na pele dos pacientes em pontos anatômicos envolvidos em cada exame. No caso da HSG os resultados mostraram que a dose na entrada da pele variou de 0,5 mGy a 73,4 mGy, com um valor médio de 22,1 mGy. A dose no útero foi estimada em 5,5 mGy, e 6,6 mGy foi a dose média estimada para os ovários. As doses de entrada na pele dos pacientes submetidos a exames de DCG variaram de 2,1 mGy a 10,6 mGy, e a dose média entre os olhos foi de 6,1 mGy. Os resultados das doses ocupacionais mostraram que, na HSG, a dose média na mão direita do médico é de 4,3 mGy por exame. Este valor é devido ao fato que o médico introduz o meio de contraste manualmente durante as exposições com contraste na histerossalpingografia. Em relação a DCG, os valores de doses ocupacionais foram da ordem dos valores ambientais, evidenciando que, dentro dos limites permitidos, não há risco para os médicos neste procedimento
