Comparação da razão sinal-ruído e da uniformidade da imagem entre aquisições com bobina de quadratura e com bobina de corpo

The signal-to-noise ratio and image uniformity analysis parameters are very important in quality control of an MRI scanner. They are measured in regular tests with phantoms. In these tests, however, used to quadrature coil, which has been most widely used clinically, and, therefore, was replaced in the procedures for body coil. In order to understand the difference between these two parameters in these coils, the study aimed to analyze the images acquired from four different phantoms in the same equipment under the same conditions for comparison purposes. With these results, it can be concluded that the body coil signal-to-noise ratio has always smaller than the quadrature in any projection, whereas the image uniformity is larger

A seleção dos conteúdos cartográficos presentes na proposta curricular dos cadernos São Paulo faz escola de geografia do 6. ano do ensino fundamental II

Cartography is one of the languages that express the knowledge of the geographic space and, therefore, the official curriculum proposals have highlighted the importance of the geography teaching which articulates its contents with this language in primary education. So, we present an analysis of the content selected to the curriculum mapping specifications of the São Paulo faz escola material, specifically for the 6th year of Elementary School II, version 2009. From the perspective of qualitative research, with instruments and techniques of quantitative and qualitative research, we analyzed documents and observed little concern with the proposition works that present the physical and social characteristics of the state of São Paulo. Also, we noticed the lack of concern with representations in local and regional scales. The research brings many examples on the global scale. It explores few activities using graphics and charts. Despite bringing thematic maps in their entirety, it does not show an example of conical projection as well as cartograms and anamorphosis. Furthermore, the trend of a technicist education is announced in the document

Estudo da influência do lineamento Tibagi e Sinclinal de Torres na estruturação da porção norte da bacia de Pelotas

The area of this work is located along the Northern portion of the Pelotas´s basin. The onshore region extends from the Southern portion São Paulo State to the North of Rio Grande do Sul State, with a total area of 440 530 km ². The objective of the research is to characterize the main geological structures of the outcropping basement in the Paraná Basin and its correlation with the offshore portion of the Pelotas Basin. The characterization was performed through the integration of surface (SRTM images and outcrops) and subsurface data (seismic data and well logs), the method includes the use of remote sensing techniques and seismic interpretation. The main structures to be analyzed are the Tibagi Lineament and the “Torres Syncline in order to verify its influence on the geological evolution and deformation of the basin. As result, it was identified the continuity of the both structures inside the offshore basin (Pelotas Basin); but only the Tibagi Lineament represents an important structural feature in the offshore basin. In this sense, the Tibagi lineament shows a NW-SE direction along the both basins (Pelotas and Paraná) and it is defined by drainages and relief on the continental portion. It was classified as a graben structure limited by normal faults and it also was verified a trend of faults inside the lineament that cuts all the sedimentary package of Itararé Group from Paraná Basin. The Torres syncline is a structure that connects the arches of Ponta Grossa and Rio Grande, showing NW-SE orientation and a low angle dip in the NW direction. Its projection into the Pelotas Basin was not recognized by the methods applied in this work, because a preliminary analyze indicates that its projection corresponds to a structural high inside the Pelotas Basin

Distribuição e dispersão dos níveis radiométricos do setor técnico de medicina nuclear do hospital das clínicas da faculdade de medicina de botucatu

Nuclear medicine uses non-sealed sources for exams and treatments, because the movement of these sources, source of patients injected or not, involve a wide range of environmental radiometric levels. To better control of these levels this study was aimed at monitoring points strategically distributed in all environments Sector Technical Nuclear Medicine, Hospital of the Botucatu Medical School, performing two measurements at random times daily for a period of three months, sampling the normal routine of the sector. The detector Geiger-Muller was used for the acquisition of exposure rates of the points, efficiency and reprodutibility test have shown good performance of this equipment for this purpose. The results allowed to make a projection of annual dose for each environment indicating higher risks for Occupationally Exposed Individuals as well as Public Individuals compared with the limits established by the National Commission of Nuclear Energy. Was developed a spatial map of dose that can be used as a visual warning to the regions with the highest exposure to ionizing radiation, enabling reduced risk of a potential exposure

Nós falamos da vida

It is said that a film producer to receive a prestigious award in the United States thanked saying We Speak of Life. Maybe this isone of the reasons for the fascination produced by this art. Life is a movie. The film celebrates life. The book We Speak of Lifeshows who are professionals of the cinema exhibition, those who are in the small microcosm that is the projection room and usuallyare not remembered by the general public

Estudo in vitro da anatomia das projeções de esmalte cervical em dentes molares

The cervical enamel projection (CEP) is an anatomic variation that can be found in the cement enamel junction, it´s recognition and early diagnosis improves outcome the tooth involved, allowing greater efficiency in treatment. The knowledge of the location, grade and incidence of CEP is decisive on prevention and treatment of periodontal disease. It were studied 1200 molars (600 mandibular molars and 600 maxillary molars) separated from the collection of teeth on the Discipline of Anatomy in FOSJCampos - UNESP. Each group of 600 teeth was separated from the second side (300 teeth) and the second type (first, second or third molar). Each tooth had thoroughly inspected the cervical region, in all their faces, in order to verify the incidence and the grade of CEP in each surface. It was found that the CEP covered in 278 (23,17%) teeth was 146 (52,52%) mandibular molars and 132 (47,48%) maxillary molars. The CEPs were concentrated on a tooth surface in 222 (79,86%) teeth, in two surfaces 53 (19,06%) teeth, and in three surfaces in three (1,08%) teeth. From the total of 4.800 surfaces examined the CEPs were found in 337 surfaces, and 228 (67,66%) surfaces of the grade I, 60 (17,8%) grade II and 49 (14,54%) grade III. The buccal surface presented 207 (61,42%) CEP, the lingual surface in 57 (16,91%), the mesial surface in 35 (10,39%) and the distal surface in 38 (11,28%) CEP. The results of this study demonstrated that the CEPs have focused more on the mandibular teeth on only one surface of the tooth, the grade I was the most found and the buccal surface the most involved

Anatomia floral de espécies de Bulbophyllum sect. Micranthae (Orchidaceae, Asparagales)

Bulbophyllum, which comprises 1876 species, is considered the second largest genus of angiosperms, with a pantropical distribution. The morphological and anatomical floral studies in the genus are incipient, with data restricted to the gynostemium and lip of some species. Based on molecular data, six sections were recognized within Bulbophyllum at the Neotropics, amongst them Bulbophyllum sect. Micranthae, which comprises 12 species distributed in central South America. We aimed to study the floral anatomy of six species of Bulbophyllum sect. Micranthae, in order to determine useful characters to differentiate them and contribute to the anatomical characterization of the section as a whole. Floral anatomy was assessed through usual techniques of light microscopy. The data found here for B. adiamantinum, B. chloroglossum, B. epiphytum, B. mentosum, B. micranthum and B. rupicolum allowed to identificate the presence of glandular trichomes and the possible presence of a secretory region on the lip, which might produce substances used as a reward to pollinators. The most significant anatomical characters to the species characterization were the shape and ornamentation of the outer periclinal walls of the epidermal cells, as well as the number of vascular bundles in dorsal and lateral sepals and at the lip. The data also allowed the differentiation between B. epiphytum and B. rupicolum, species very similar in morphology and phylogenetically related. Besides that, the data also allowed the discussion regarding the maintenance of B. mentosum within the section: although its inclusion is supported by molecular studies, the anatomical data here presented shows greater differences compared to the other species, not supporting its maintenance in Bulbophyllum sect. Micranthae

Juventude sobre pressão: um fórum alemão e uma obra de Octávio Ianni

In the 20th century, youth has become a western myth rather than an important social category in the projection of future societies. The Right-wing was ahead of left-wing movements supporting national political projects. The crisis in the Welfare state and socialism system disoriented the right and left-wing movements. The myth of youth as reference for the progressive development of history was destroyed. Youth movements, consolidated in some student movements and supported by some religious organizations took over this reference position. However, these new youth movements are rarely engaged in political or environmentalist projects. The violence that originates from disturbing practices of social reproduction puts youth under pressure.

Aparelho extrabucal como recurso auxiliar para alinhamento e nivelamento no tratamento orto cirúrgico de má oclusão classe III esquelética

When well indicated, the orthodontic surgical approach is the ideal treatment mean for Skeletal Class III adult patients. To improve facial esthetic results from orthognatic surgery, the leveling and alignment of maxillary dental arch must be achieved with minimal inclination and projection or even retro-inclination of anterior upper teeth. During a pre-surgical phase of 12 months, headgear bilateral force of 150 g/F was applied to the upper molars of a 22 years old male compliant patient with Class III skeletal malocclusion, to provide an upper teeth control of mesial tipping and projection during alignment and leveling. The ideal occlusal parameters required for surgical procedure were achieved without dental extractions permitting a total treatment period of 37 months. The outcomes remained stable over 3 years follow up after the removal of the appliance. The results indicate that, although headgear use depends greatly on patient compliance, when well indicated it is an interesting alternativetopromote dentaldecompensationon pre-surgical period, in order to allow surgical correction of skeletal Class III malocclusion.

Análise dos troncos radiculares, abertura da raízes e projeções cervicais de esmalte de furcas de molares superiores e inferiores: Estudo in vitro

Periodontal treatment of teeth with furcation lesions often have unpredictable results due to several factors that may hinder therapy or influence the progress of periodontal disease. Of these, the length of the root trunk may contribute to the early injury of the furcations or even cause complications for the application of the treatment; the opening of the roots can guide the type of treatment to be instituted and cervical enamel projections may hinder the instrumentation of the region or even act as a retention plate niche. Thus, the purpose of this study was measured using a digital caliper, root logs database 400 molar both the 1st and the 2nd and both upper and lower as well as analyze using appropriate index type projection cervical enamel and through appropriate classification the opening of the roots in order to guide the diagnosis and treatment plan. We conclude that there is variation in measures of root trunk between the faces of the teeth examined and that greater cervical enamel projection (ECP) correlates with a decrease in the length of the root trunk in the sample evaluated as the first molars have higher occurrence of roots with a degree of opening larger than the second molars.

China e a Ásia Central: petróleo, segurança e os Estados Unidos

In the last two decades, the United States have substantially increased their presence in Central Asia. Therefore their presence left China in an uncomfortable position, as China seeks to build a stable and peaceful environment in its near abroad, having under its influence all the countries of Central Asia. One of the ways used by the Chinese government to get closer to the countries of this region is through the oil. Being so, the Chinese oil companies buy rights of exploitation of oil and gas reserves in Central Asia and through this establishes and deepens friendly ties with these countries. This practice became known as oil diplomacy. This new tool of the Chinese government has a double effect: it increases the projection of the Chinese power and dilutes the American influence in the region. In other words, it displeases the United States, and in turn tries to be even more present in Central Asia. The main goal to be worked in this study is how the oil diplomacy increases Chinese influence in Central Asia and dilutes American power in the region. It also aims to explain how the United States uses its presence in Central Asia and on sea lines of communication used to transport oil to contain the Chinese expansion

O grupo como produtor de singularidades: o processo subjetivo como forjador de singularidades frente às pessoas que vivem com as DSTs

The personal experience respective is a description of an psychosocial intervention effectuated in the year of 2007 in an institution not government, in the city of Taubaté, with a group of women infected with the virus HIV. We will present in the short form our work, which happened through a therapeutic group, that had as device, the production of new process of subjectivizing with these women in the conduction of them condition of life after the infection with the virus HIV. To determine our actions use the theoretical assumptions of genealogy, of psychology and the theory of institutional operating group with emphasis on aspects of group discussion. During approximately twelve meetings with the denser group work topics such as social violence (inequality of rights, prejudice and stigma), treatment of the condition of serum positive when marked by ambivalence to treatment and the use of defense mechanisms: denial, projection and omnipotence, the weak and intense physical and mental suffering resulting from this process.We end our exhibition while presenting the discursive constructions and, consequently, the multiforms singular potentialities of the group that appeared with our psychosocial interventions.
