    Full Text Available The research provides a description of the SciELO journals portal and the DOI identifier through its range, year of creation, history, management, policy, structure, ISBN-A and reference sources. It provides information on the implementation of the DOI in citations styles APA and Vancouver, and standards ISO 690-2010 and ABNT6023-2002. The work aimed to explore the degree of implementation of the DOI in scientific journals in SciELO, identify where DOI display, knowing the amount of publishers as DOI prefix, determine the number of journals titles including the ISSN suffix code and identify the degree of implementation of the DOI in the styles and standards of citations available in SciELO. Descriptive methodology was applied where data were collected through direct observation of the websites of the 898 current journals available between the months of December 2012 and January 2013 in SciELO portal. It concludes that less than 50% of the countries in SciELO are currently using the DOI in its publications, primarily displayed code in HTML files, only 30 of the 929 publishers implemented it and most include the ISSN identifier within the suffix. While using the DOI in all citations of the articles, not does so strict as the provisions of the rules and styles.

    Full Text Available Rapid development of information technology in recent years has brought over also the problem of the protection of author's rights related to copyrighted works on electronic media. Information and law specialists were intensively working on this problem for several years and the result has been a new system of labelling copyrighted works on the Internet, called DOI (Digitial Object Identifier. The system was developed in the United States. At the time of the presenta tion of DOI at the Bookfair in Frankfurt, 250.000 author works were labelled with DOI. The system is universal and enables the inclusion of the present standard identifiers (ISBN, ISSN, SICI. The fact that DOI identifier stays "glued on" forever, makes the identification of the carrier of copyright possible at any moment. The DOI system presents the infrastructure system for trading in and use of copyrighted works over the Internet in the third millenium.

  12. PDS, DOIs, and the Literature

    Science.gov (United States)

    Raugh, Anne; Henneken, Edwin

    The Planetary Data System (PDS) is actively involved in designing both metadata and interfaces to make the assignment of Digital Object Identifiers (DOIs) to archival data a part of the archiving process for all data creators. These DOIs will be registered through DataCite, a non-profit organization whose members are all deeply concerned with archival research data, provenance tracking through the literature, and proper acknowledgement of the various types of efforts that contribute to the creation of an archival reference data set. Making the collection of citation metadata and its ingestion into the DataCite DOI database easy - and easy to do correctly - is in the best interests of all stakeholders: the data creators; the curators; the indexing organizations like the Astrophysics Data System (ADS); and the data users. But in order to realize the promise of DOIs, there are three key issues to address: 1) How do we incorporate the metadata collection process simply and naturally into the PDS archive creation process; 2) How do we encourage journal editors to require references to previously published data with the same rigor with which they require references to previously published research and analysis; and finally, 3) How can we change the culture of academic and research employers to recognize that the effort required to prepare a PDS archival data set is a career achievement on par with contributing to a refereed article in the professional literature. Data archives and scholarly publications are the long-term return on investment that funding agencies and the science community expect in exchange for research spending. The traceability and reproducibility ensured by the integration of DOIs and their related metadata into indexing and search services is an essential part of providing and optimizing that return.

  15. ESDIS DOI System, Approach, and Future Direction

    Science.gov (United States)

    Wanchoo, L.; James, N.

    2013-12-01

    NASA's Earth Science Data and Information System (ESDIS) Project began investigating the use of Digital Object Identifiers (DOIs) in 2010 with the goal of assigning DOIs to various data products. These data products are archived and distributed by various Distributed Active Archive Centers (DAACs) located across the United States. Each data center has a unique approach and process for generating and archiving a variety of data products that are used for global change research. These varied approaches present a challenge for developing a DOI solution that fits all the possible variations. To address this challenge, ESDIS developed processes, guidelines, and several models for creating and assigning DOIs. Initially the system was started as a prototype approach and now it is fully operational. In February 2012, ESDIS joined the California Digital Library (CDL) EZID for registering the EOSDIS-related DOIs. ESDIS's DOI operational process allows for reserving DOIs while data providers are finalizing the DOIs and its associated elements. This flexibility allows data providers to embed and test the DOI in the data product metadata before formally registering with EZID. Data providers can change any DOI metadata, including the DOI name as long as it has not been registered or reserved by another data provider. ESDIS assures the uniqueness of the DOI names before it is registered. Currently, ESDIS has 146 data product DOIs registered with EZID and data providers have reserved an additional 93 DOIs with ESDIS. A semi-automated approach is being developed for processing and validating the DOI information provided by the data providers and will cover all the steps from the collection to the registration of DOIs. ESDIS's DOI concept utilizes a few mandatory metadata elements that effectively identify the data products and the source of availability. Of these elements, the Uniform Resource Locator (URL) attribute has the very important function of identifying the landing page

    Full Text Available Após considerações a propósito das manifestações clínicas das uveomeningencefalites, são relatados dois casos com características clínicas ligeiramente diferentes. No caso 1 tratava-se da doença de Harada, tendo o paciente apresentado quadro meningítico agudo acompanhado de confusão mental. O exame do líquido cefalorraquidiano evidenciou um quadro inflamatório do tipo linfo-monocitário e o paciente evoluiu com distúrbios acentuados da memória e uveíte bilateral. Após alguns meses de evolução, a doença deixou como seqüelas uma síndrome de Korsakoff e ambliopia acentuada no olho esquerdo. No caso 2 tratava-se de doença de Behcet, tendo o paciente apresentado dois surtos de meningite do tipo linfomonocitário, lesões herpetiformes na genitalia e uveíte no olho direito que evoluiu para amaurose. São feitas considerações sobre os aspectos etiopatogênicos destas afecções e sobre o controvertido uso dos corticosteróides em seu tratamento.

  17. Evolution of DOI Usage and Registration

    2017-12-01

    NASA's Earth Science Data and Information System (ESDIS) Project has implemented an automated system for assigning Digital Object Identifiers (DOIs) to Earth Science data products being managed by its network of 12 distributed active archive centers (DAACs). Using the ESDIS DOI system, over 3000 DOIs have been assigned, registered, and made publicly accessible while over 1000 assigned DOIs are being held in reserve until ready for public use. The goal is to assign a DOI to each of the 8000+ data collections under ESDIS management. DOIs make it easier for researchers to discover and use earth science data and they enable users to provide valid citations for the data they use in research. Also for the researcher wishing to reproduce the results presented in science publications, the DOI can be used to locate the exact data or data products being cited. ESDIS DOIs also provide data "Provenance" which is information about the creation and history of the data in question. This would include when the data was collected, which instrument was used to collect the data, and the version of the product at the time the DOI was assigned. Over the past few years, requests for DOIs have increased significantly as DAACs assign DOIs to both legacy data from earlier missions and new data products from in-orbit missions. This study will evaluate the evolution of DOI registration and its usage over those years comparing data products as they are organized by mission, science discipline and data product level. It is hoped that the study results will help NASA determine how to prioritize future products for DOI assignment and inform future studies that would identify trends over time of increased use of data citations resulting in increased discovery and distribution of NASA Earth science data products.

    Spatial resolution degradation in PET occurs at the edge of Field Of View (FOV) due to parallax error. To improve spatial resolution at the edge of FOV, Depth-Of-Interaction (DOI) PET has been investigated and several methods for DOI positioning were proposed. In this paper, a DOI-PET detector module using two 8x4 array avalanche photodiodes (APDs) (Hamamatsu, S8550) and a 2 cm long LYSO scintillation crystal was proposed and its DOI characteristics were investigated experimentally. In order to measure DOI positions, signals from two APDs were compared. Energy resolution was obtained from the sum of two APDs' signals and DOI positioning error was calculated. Finally, an optimum DOI step size in a 2 cm long LYSO were suggested to help to design a DOI-PET

    Full Text Available Construímos um modelo de equilíbrio geral dinâmico de dois setores com o intuito de investigar o comportamento dos ciclos reais brasileiros. Quando os investimentos dos dois setores são agregados de acordo com uma Cobb-Douglas para formação de capital, o modelo é consistente com as volatilidades cíclicas dos componentes das contas nacionais e com a natureza contracíclica das exportações líquidas e do câmbio real. Caso a elasticidade de substituição entre o consumo de comercializáveis e de não comercializáveis seja baixa, o modelo também reproduz a volatilidade observada no câmbio real.We construct a two-sector dynamic general equilibrium model to investigate the behavior of the Brazilian business cycles. When investments from each sector are aggregated according to a Cobb-Douglas for capital formation, the model is consistent with the cyclical volatilities of national income components as well as with the countercyclical character of net exports and real exchange rates. If the elasticity of substitution between consumptions of tradeables and non-tradeables is low, the model can also reproduce the observed real exchange rates volatilities.

  11. Phoswich solutions for the PET DOI problem

    A high spatial resolution in PET can be achieved by using small detector elements. To maintain good sensitivity these elements have to be quite long, thus introducing parallax error and making the spatial resolution non-uniform over the image volume. Uniformity of spatial resolution can be improved by utilizing depth-of-interaction (DOI) information to reduce the parallax error. In the present study we have focused on phoswich approaches based on interacting scintillators, that is, a phoswich combination in which one scintillator emits light in the excitation band of the other. We have looked at LaBr 3 :Ce and LaCl 3 :Ce and the interactions of those two scintillators with LSO:Ce, GSO:Ce and YSO:Ce. The reasons to use the two Lanthanum scintillators are twofold: light output is high and the two different emission wavelengths, 350 nm (LaCl 3 :Ce) and 380 nm (LaBr 3 :Ce) may produce different interactions with the three oxyorthosilicate scintillators. In addition a possible DOI detector comprising LuAG:Pr pixels with a thin LSO:Ce layer at one end has been evaluated. A Bollinger-Thomas set-up was used to measure luminescence rise and luminescence decay time characteristics in all cases. When using LaCl 3 :Ce, the phoswich combinations with YSO:Ce and GSO:Ce showed phoswich decay time characteristics as expected for a simple convolution of the decay times of the two phoswich components. A correction was needed, however, for the LaCl 3 :Ce-LSO:Ce phoswich due to the LSO:Ce intrinsic activity. For the LaBr 3 :Ce-LSO:Ce phoswich, corrections were needed for non-interacting LaBr 3 :Ce light in addition to the expected phoswich interaction.

Fourty per cent of the books was published by trade publishers, 26% by the Universities (47 -94%- were doctoral theses and 19% by public organizations. It is concluded that the ISBN Spanish database can be a good tool to retrieve Spanish books dealing with alcoholism, but some limitations, that are extensively discussed, must be taken into account when a study of these characteristics is performed using this database.

    El alcoholismo es uno de los grandes problemas para la salud que se presentan en la población española. El objetivo de este estudio fue ver si en España se publicaban libros sobre alcohol y alcoholismo y analizar las características de los mismos; asimismo, se analizaron las características de la base de datos de la Agencia Española ISBN, que se utilizó en el estudio. Se recuperaron los libros que incluyeran en algún campo: alcohol*, alkohol*, etanol*, etili

    Full Text Available  El libro Teaching Geography Creatively, editado por Stephen Scoffham, supone una fuente de recursos y orientaciones didácticas fundamentadas en investigaciones recientes de gran interés para aquellos docentes de Infantil y Primaria que hayan decidido apostar por la creatividad en sus aulas. Estas orientaciones no solo buscan la motivación del alumnado sino que, en la línea del constructivismo, defienden la necesidad de fomentar un pensamiento crítico en ellos para construir aprendizajes con sentido y conectados realmente con su mundo. Se pretende así acabar con la idea que asocia la enseñanza de la geografía con el aprendizaje memorístico y pasivo, dentro de cuatro paredes. Tal y como hacen otros títulos de la serie en la que se integra, Learning to Teach in the Primary School, esta monografía defiende también una comunicación bidireccional en la transmisión del conocimiento (alumno-profesor, alumno-alumno y un currículo flexible que permita un aprendizaje creativo, donde el centro de atención sea el proceso de enseñanza-aprendizaje y no los resultados.

    Full Text Available Descrevemos dois casos de distrofia neuroaxonal infantil ou doença de Seitelberger, que é doença rara, neurodegenerativa, com herança autossômica recessiva. O primeiro caso, sexo masculino, com 8 anos de idade, apresentava atraso do desenvolvimento psicomotor, ataxia e fraqueza muscular. Ao exame físico foi encontrado nistagmo horizontal e vertical com palidez do disco óptico, hipotonia e arreflexia profunda. O segundo caso, sexo masculino, com 1 ano e 6 meses de idade, apresentava atraso do desenvolvimento psicomotor e convulsões. No exame físico, apresentava atrofia de nervo óptico, hipertonia e hiperreflexia. A biópsia de nervo sural de ambos os pacientes mostrou aumento dos axônios, compatível com distrofia neuroaxonal. As características clínicas pleomórficas, bem como os achados neurofisiológicos variáveis tornam difícil firmar o diagnóstico, o qual é ajudado pela confirmação anatomopatológica dos esferóides neuroaxonais.

  16. New DOI identification approach for high-resolution PET detectors

    International Nuclear Information System (INIS)

    Choghadi, Amin; Takahashi, Hiroyuki; Shimazoe, Kenji

    2016-01-01

    Depth-of-interaction (DOI) Identification in positron emission tomography (PET) detectors is getting importance as it improves spatial resolution in both conventional and time-of-flight (TOF) PET, and coincidence time resolution (CTR) in TOF-PET. In both prototypes, spatial resolution is affected by parallax error caused by length of scintillator crystals. This long length also contributes substantial timing uncertainty to the time resolution of TOF-PET. Through DOI identification, both parallax error and the timing uncertainty caused by the length of crystal can be resolved. In this work, a novel approach to estimate DOI was investigated, enjoying the interference of absorbance spectrum of scintillator crystals with their emission spectrum. Because the absorption length is close to zero for shorter wavelengths of crystal emission spectrum, the counts in this range of spectrum highly depend on DOI; that is, higher counts corresponds to deeper interactions. The ratio of counts in this range to the total counts is a good measure to estimate DOI. In order to extract such ratio, two photodetectors for each crystal are used and an optical filter is mounted only on top of one of them. The ratio of filtered output to non-filtered output can be utilized as DOI estimator. For a 2×2×20 mm 3 GAGG:Ce scintillator, 8-mm DOI resolution achieved in our simulations. (author)

    Ohi, Junichi; Tonami, Hiromichi

    2007-01-01

    In this study, we were conducting basic research on a whole-body depth of gamma-ray interaction (DOI) positron emission tomography system which provides spatial resolution that is both high and uniform, and also minimizes costs. The detectors consist of double-layer 9x10 GSO/GSO phoswich crystal blocks, a light guide and two rectangular PMTs. Individual crystal sizes are 2.45x5.1x15 mm 3 , and each layer of crystal blocks has a different decay time. Many of the circuit boards used in our current conventional PET system (SET-3000G SHIMADZU Japan) have been optimized for DOI acquisition. The detectors are arranged to form a 332.5 mm radius detection ring, and spatial resolution is obtained from the center to the edge of the 250 mm radius field of view. The effect of DOI was confirmed using a comparison with the non-DOI systems

  7. Did Oligocene crustal thickening precede basin development in northern Thailand? A geochronological reassessment of Doi Inthanon and Doi Suthep

    Science.gov (United States)

    Gardiner, Nicholas J.; Roberts, Nick M. W.; Morley, Christopher K.; Searle, Michael P.; Whitehouse, Martin J.

    2016-01-01

    The Doi Inthanon and Doi Suthep metamorphic core complexes in northern Thailand are comprised of amphibolite-grade migmatitic gneisses mantled by lower-grade mylonites and metasedimentary sequences, thought to represent Cordilleran-style core complexes exhumed through the mobilization of a low-angle detachment fault. Previous studies have interpreted two metamorphic events (Late Triassic and Late Cretaceous), followed by ductile extension between the late Eocene and late Oligocene, a model which infers movement on the detachment at ca. 40 Ma, and which culminates in a rapid unroofing of the complexes in the early Miocene. The Chiang Mai Basin, the largest such Cenozoic Basin in the region, lies immediately to the east. Its development is related to the extension observed at Doi Inthanon and Doi Suthep, however it is not definitively dated, and models for its development have difficulty reconciling Miocene cooling ages with Eocene detachment movement. Here we present new in-situ LA-ICP-MS and SIMS U-Pb age data of zircon and monazite grains from gneiss and leucogranite samples taken from Doi Inthanon and Doi Suthep. Our new zircon data exhibit an older age range of 221-210 Ma, with younger ages of ca. 72 Ma, and 32-26 Ma. Our monazite data imply an older age cluster at 83-67 Ma, and a younger age cluster of 34-24 Ma. While our data support the view of Indosinian basement being reworked in the Cretaceous, they also indicate a late Eocene-Oligocene tectonothermal event, resulting in prograde metamorphism and anatexis. We suggest that this later event is related to localized transpressional thickening associated with sinistral movement on the Mae Ping Fault, coupled with thickening at the restraining bend of the Mae Yuan Fault to the immediate west of Doi Inthanon. Further, this upper Oligocene age limit from our zircon and monazite data would imply a younger Miocene constraint on movement of the detachment, which, when combined with the previously recorded Miocene

  14. Isolation of 2-deoxy-scyllo-inosose (DOI)-assimilating yeasts and cloning and characterization of the DOI reductase gene of Cryptococcus podzolicus ND1.

    2018-04-01

    2-Deoxy-scyllo-inosose (DOI) is the first intermediate in the 2-deoxystreptamine-containing aminoglycoside antibiotic biosynthesis pathway and has a six-membered carbocycle structure. DOI is a valuable material because it is easily converted to aromatic compounds and carbasugar derivatives. In this study, we isolated yeast strains capable of assimilating DOI as a carbon source. One of the strains, Cryptococcus podzolicus ND1, mainly converted DOI to scyllo-quercitol and (-)-vibo-quercitol, which is a valuable compound used as an antihypoglycemia agent and as a heat storage material. An NADH-dependent DOI reductase coding gene, DOIR, from C. podzolicus ND1 was cloned and successfully overexpressed in Escherichia coli. The purified protein catalyzed the irreversible reduction of DOI with NADH and converted DOI into (-)-vibo-quercitol. The enzyme had an optimal pH of 8.5 and optimal temperature of 35°C, respectively. The k cat of this enzyme was 9.98 s -1 , and the K m values for DOI and NADH were 4.38 and 0.24 mM, respectively. The enzyme showed a strong preference for NADH and showed no activity with NADPH. Multiple-alignment analysis of DOI reductase revealed that it belongs to the GFO_IDH_MocA protein family and is an inositol dehydrogenase homolog in other fungi, such as Cryptococcus gattii, and bacteria, such as Bacillus subtilis. This is the first identification of a DOI-assimilating yeast and a gene involved in DOI metabolism in fungi. Copyright © 2017 The Society for Biotechnology, Japan. Published by Elsevier B.V.

  2. Study of continuous DOI positioning for solid-state PET detectors

    International Nuclear Information System (INIS)

    Lee, Chae Hun

    2007-02-01

    PET is a nuclear imaging technique that measures the spatial and temporal distribution of compounds labeled with a positron emitting radionuclide introduced into a subject to be determined non-invasively. Spatial resolution degradation occurs at the edge of Field Of View (FOV) due to parallax error. To improve spatial resolution at the edge of FOV, Depth-Of-Interaction (DOI) PET has been investigated and there are several methods for DOI positioning. Among DOI positioning methods, sharing scintillation light output is the cost-effective and accurate method while solid-state photosensors such as Avalanche Photodiodes have been well developed. Avalanche photodiodes have internal gain by impact ionizations in high electric field. High gain and low noise are good characteristics for use in PET. In this thesis, DOI-PET detector using two APD with LSO scintillation crystal was designed and evaluated, and parameter to affect DOI positioning was investigated. Energy resolution of the designed detector was 12 % in 662 keV photopeak. Comparing photopeak channels of two APD output, DOI position was measured. DOI positioning error was ±2.5 mm. DOI resolution in current DOI-PET systems is still ∼ cm. Minimum 4 step positions can be obtained with 2 cm long LSO crystal in this result

    2004-01-01

    As a recent trend of DOI measurement for the PET, a simple method of utilizing the light attenuation properties of scintillation materials has been paid attention. We have studied the DOI resolutions for less expensive materials as BGO in both the bench test and the simulation by GEANT4.0. By comparison with both the results, we have recognized the importance of removing the multiple Compton absorption events to obtain the better DOI information. The simulation results for the imaging resolution suggested that its deterioration attributes to the parallax error as well as the systematic displacement inherent in the present method of 3D-reconstruction

    2014-11-01

    Full Text Available The aim of our article is not to report an empirical study but to present a toolkit which can help to collect valid information about brands. The Decision-Oriented Interview, hereafter, DOI presents empirically proven behavior regularities in interviews as a collection of checklists. The DOI has shown its usefulness in different fields of interviewing e.g. as a selection interview, in forensic assessment or a method for oral examinations. The DOI collection of explicit rules for interview design, execution and summary is described as a toolkit for collecting information relevant in marketing. The purchase decisions are presented as a basis for describing brand-differentiating situations. The use of the rules collected in the DOI checklists has clear advantages over the conventional approach in which success depends on the experience of individual project managers.

    PET systems designed for specific applications require high resolution and sensitivity instrumentation. In dedicated system design smaller ring diameters and deeper crystals are widely used in order to increase the system sensitivity. However, this design increases the parallax error, which degrades the spatial image resolution gradually from the center to the edge of the field-of-view (FOV). Our group has designed a depth of interaction(DOI)-encoding small animal PET system based on monolithic crystals. In this work we investigate the restoration of radial resolution for transaxially off-center sources using the DOI information provided by our system. For this purpose we have designed a support for point like sources adapted to our system geometry that allows a spatial compression and resolution response study. For different point source radial positions along vertical and horizontal axes of a FOV transaxial plane we compare the results obtained by three methods: without DOI information, with the DOI provided by our system and with the assumption that all the γ-rays interact at half depth of the crystal thickness. Results show an improvement of the mean resolution of 10% with the half thickness assumption and a 16% achieved using the DOI provided by the system. Furthermore, a 10% restoration of the resolution uniformity is obtained using the half depth assumption and an 18% restoration using measured DOI.

    Standardizing and incentivizing the use of digital object identifiers (DOIs) to aggregate and identify both data analyzed and data generated by a research project will advance the field of astronomy to match best practices in other research fields like geoscience and medicine. An increase in the use of DOIs will prepare the discipline for changing expectations among funding agencies and publishers, who increasingly expect accurate and thorough data citation to accompany scientific outputs. The use of DOIs ensures a robust, sustainable, and interoperable approach to data citation in which due credit is given to the researchers and institutions who produce and maintain the primary data. We describe in this work the advantages of DOIs for data citation and best practices for integrating a DOI service in an astronomical archive. We report on a pilot project carried out in collaboration with AAS journals. During the course of the 1.5-year long pilot, over 75% of submitting authors opted to use the integrated DOI service to clearly identify data analyzed during their research project when prompted at the time of paper submission.

    Owing to their photosynthetic capabilities, there is increasing interest in utilizing cyanobacteria to convert solar energy into biomass. 2-Deoxy-scyllo-inosose (DOI) is a valuable starting material for the benzene-free synthesis of catechol and other benzenoids. DOI synthase (DOIS) is responsible for the formation of DOI from d-glucose-6-phosphate (G6P) in the biosynthesis of 2-deoxystreptamine-containing aminoglycoside antibiotics such as neomycin and butirosin. DOI fermentation using a recombinant Escherichia coli strain has been reported, although a carbon source is necessary for high-yield DOI production. We constructed DOI-producing cyanobacteria toward carbon-free and sustainable DOI production. A DOIS gene derived from the butirosin producer strain Bacillus circulans (btrC) was introduced and expressed in the cyanobacterium Synechococcus elongatus PCC 7942. We ultimately succeeded in producing 400 mg/L of DOI in S. elongatus without using a carbon source. DOI production by cyanobacteria represents a novel and efficient approach for producing benzenoids from G6P synthesized by photosynthesis.

    The objective of this study was to choose the crystal surface finishing for a dual-ended readout (DER) DOI detector. Through Monte Carlo simulations and experimental studies, we evaluated 4 crystal surface finishing options as combinations of crystal surface polishing (diffuse or specular) and reflector (diffuse or specular) options on a DER detector. We also tested one linear and one logarithm DOI calculation algorithm. The figures of merit used were DOI resolution, DOI positioning error, and energy resolution. Both the simulation and experimental results show that (1) choosing a diffuse type in either surface polishing or reflector would improve DOI resolution but degrade energy resolution; (2) crystal surface finishing with a diffuse polishing combined with a specular reflector appears a favorable candidate with a good balance of DOI and energy resolution; and (3) the linear and logarithm DOI calculation algorithms show overall comparable DOI error, and the linear algorithm was better for photon interactions near the ends of the crystal while the logarithm algorithm was better near the center. These results provide useful guidance in DER DOI detector design in choosing the crystal surface finishing and DOI calculation methods. (paper)

    Full Text Available The present study seeks to investigate the use of the Digital Object Identifier (DOI in the scientific journals of Communication and Information and, providing new integration utilities with the Lattes Platform. In this sense, it aims to inform the existing titles in Communication Information in electronic format, demonstrate the importance of DOI in the integration with the Lattes Platform in order to guarantee author credibility and analyze the characteristics of publications that have DOI. The methodology used for the development of this study is bibliographic, research with descriptive-descriptive characteristics. From the development of the research, it is inferred that of all the analyzed journals (33 journals, 10 titles in the evaluation of 2013 and 06 titles of the evaluation of 2014 present DOI in their publications, all have WebQualis classification, Qualis A1 in the area Communication and Information. Most publications are international and only 3 titles are national. It is necessary that journals, principally national ones, accompany new technologies such as DOI for objects and ORCID for the identification of people, bringing more mechanisms that guarantee authors 'credibility and to bring the researchers' connection, and both can already be adopted in the Platform Lattes.

    We quantified binding sites for 2,5-dimethoxy-4-iodo-phenylisopropylamine (DOI), a 5-HT2 agonist and hallucinogen, in human platelets. We incubated sections from human platelet pellets with ({sup 125}I)R-DOI with or without 1 mumol/L ketanserin, followed by autoradiography and computerized microdensitometry. We corrected the values of binding density by the protein content of each section with a densitometric protein assay. The present method revealed a single class of high affinity binding sites for ({sup 125}I)R-DOI, with a Kd of 6.4 +/- 0.7 nmol/L and a Bmax of 100 +/- 10 fmol/mg protein. Kd and Bmax for ({sup 125}I)R-DOI determined by the classical membrane binding assay, were 2.7 +/- 0.4 nmol/L and 100 +/- 10 fmol/mg protein, respectively. The present method is precise, very sensitive, and allows the characterization of ({sup 125}I)R-DOI binding in sections obtained from as little as 3 ml of blood. Standardization is possible after correction by the protein content of each individual section.

    There have been many studies on Depth Of Interaction (DOI) identification for high resolution Positron Emission Tomography (PET) systems, including those on phoswich detectors, double-sided readout, light sharing methods, and wavelength discrimination. The wavelength discrimination method utilizes the difference in wavelength of stacked scintillators and requires a color sensitive photodetector. Here, a new silicon photomultiplier (SiPM) coupled to a color filter (colorSiPM) was designed and fabricated for DOI detection. The fabricated colorSiPM has two anode readouts that are sensitive to blue and green color. The colorSiPM's response and DOI identification capability for stacked GAGG and LYSO crystals are characterized. The fabricated colorSiPM is sensitive enough to detect a peak of 662 keV from a 137 Cs source.

    For a high resolution animal positron emission tomography (PET), depth-of-interaction (DOI) is a useful method to improve both spatial resolution and sensitivity. Gd 2 SiO 5 (GSO) with different amounts of Ce can provide different decay times and is ideal for DOI detector using pulse shape analysis. Dual layer DOI GSO block detectors using different amounts of Ce were developed for a new animal PET. The DOI GSO block detector employed two types of GSOs; one with 1.5 mol% Ce concentration (decay time: 35 ns) and the other with 0.5 mol% (decay time: 60 ns). These two GSO types were optically coupled in the DOI direction. The sizes of single GSOs were 1.9 mmx1.9 mmx6 mm and 1.9 mmx1.9 mmx9 mm, for 1.5 and 0.5 mol%, respectively. These GSO were arranged by 11x37 matrix and optically coupled to three position sensitive photomultiplier tubes (PSPMTs), where the PSPMTs used were Hamamatsu R8520U-00-C12. Different lengths of reflectors were used between crystals to increase the useful field-of-view (FOV) of the PSPMT and to avoid the dead areas between PSPMTs. With this configuration, almost all islands in a 2-D position histogram corresponding to GSO cells could be separated. The width of the GSO block was 22 mm in the transaxial direction and 74 mm in axial direction with no gaps. Also, two types of GSO of different decay time could be separated using dual integration method for pulse shape analysis. These results indicate that developed block detectors might be useful for a high resolution and high sensitivity animal PET with dual layer DOI detection capability, with no gaps in transaxial or axial directions.

    We report a new design of a detector module with depth of interaction (DOI) based on a quasi-monolithic LSO crystal, a multi-channel sensor, and maximum-likelihood position-estimation (MLPE) algorithm. Light transport and detection were modeled in a quasi-monolithic crystal using DETECT2000 code, with lookup tables (LUTs) built by simulation. Events were well separated by applying the MLPE method within 2.0 mm spatial resolution in both trans-axial and DOI directions. These results demonstrate that the proposed detector provides dependable positioning capability for small animal positron emission tomography (PET)

The two representations provide explicit expressions for the stress prior to and after Rouse relaxation of chain stretch......, respectively. The maximum deviations from the exact representations in simple shear, biaxial extension and uniaxial extension are of order 2%.

    Fundamentally, data publication seeks to provide improved access, trust and utility for data users accompanied by improved recognition for data providers. The features of persistent identifier schemes used in this context and the policies of providers of their resolver systems can greatly contribute towards these aims! Unfortunately, we also recognize situations where identifier systems undermine some of our lofty data publication aims. From our 7 years of successful experience with the data journal ESSD, we will present our practical observations as well as future requirements on the DOI-system in particular, such as: * Most scientists contributing to or drawing benefit from ESSD seem to understand the notion of published data in the sense of a static, citable entity to build on, relying on its long term availability and integrity (as is the case with journal articles), secured by DOIs. * It is still true that many data providers - individuals or projects - can not find a repository for their (type of) data which would provide a DOI (or other persistent identifier) and that many data centers and databases holding valuable data have a hard time adding DOIs as a feature of their systems for conceptual, legacy or funding reasons. * The typical evolution of many important data collections or data products - such as the Global Carbon Budget - can adequately be tracked with yearly (or less frequent) issues of dataset and data article, each having a new DOI. However, issuing a new DOI for a dataset extended in time clashes with many producers' wish to amass all references to the developing dataset under one citation (and one DOI). * Current practises with DOIs and metadata associated with DOIs need to be clarified and amended so the identifier systems can and do express and track the relationships between versions of data, addressing extensions, corrections, modifications, revisions and retractions in an unambiguous (and machine readable) manner, while also removing

    A depth-of-interaction (DOI) detector is required for developing a high resolution and high sensitivity PET system. Ce-doped Gd 3 Al 2 Ga 3 O 12 (GAGG fast: GAGG-F) is a promising scintillator for PET applications with high light output, no natural radioisotope and suitable light emission wavelength for semiconductor based photodetectors. However, no DOI detector based on pulse shape analysis with GAGG-F has been developed to date, due to the lack of appropriate scintillators of pairing. Recently a new variation of this scintillator with different Al/Ga ratios—Ce-doped Gd 3 Al 2.6 Ga 2.4 O 12 (GAGG slow: GAGG-S), which has slower decay time was developed. The combination of GAGG-F and GAGG-S may allow us to realize high resolution DOI detectors based on pulse shape analysis. We developed and tested two GAGG phoswich DOI block detectors comprised of pixelated GAGG-F and GAGG-S scintillation crystals. One phoswich block detector comprised of 2×2×5 mm pixel that were assembled into a 5×5 matrix. The DOI block was optically coupled to a silicon photomultiplier (Si-PM) array (Hamamatsu MPPC S11064-050P) with a 2-mm thick light guide. The other phoswich block detector comprised of 0.5×0.5×5 mm (GAGG-F) and 0.5×0.5×6 mm 3 (GAGG-S) pixels that were assembled into a 20×20 matrix. The DOI block was also optically coupled to the same Si-PM array with a 2-mm thick light guide. In the block detector of 2-mm crystal pixels (5×5 matrix), the 2-dimensional histogram revealed excellent separation with an average energy resolution of 14.1% for 662-keV gamma photons. The pulse shape spectrum displayed good separation with a peak-to-valley ratio of 8.7. In the block detector that used 0.5-mm crystal pixels (20×20 matrix), the 2-dimensional histogram also showed good separation with energy resolution of 27.5% for the 662-keV gamma photons. The pulse shape spectrum displayed good separation with a peak-to-valley ratio of 6.5. These results indicate that phoswich DOI

This study aimed to determine which movements in the developmental sequence performed by schoolchildren are associated with age and vertical jump performance. The sample consisted of 137 elementary school children of both sexes, aged 7-10y, with height of 1.19-1.63 m, and weight of 20-60 kg. All children were selected from first- to fourth-grade classrooms of a public school of the city of Maringá, state of Pa- raná, Brazil. A Gallahue & Ozmun matrix and a jumping platform were used as research instruments. During the experiment, each child performed three jumps. Simultaneous and coordinated upward arm lift was observed in 7-year-old children. In 9-year-old children, inconsistent preparatory crouch and lack of coordination between limb movements and trunk were observed. A prevalence of upper limb motor acts was observed when considering the significant associations found between elements of the developmental sequence and vertical jump performance. In children aged 7-10y, age group and jumping performance are associated with elements of the developmental sequence of the human body as a whole, especially with regard to the upper limbs.

    Full Text Available Technique of joint reading and discussion of fiction books and movies as a method of psycho-correctional therapy with autistic children of school age and young people is presented. Cognitive, emotional-volitional sphere deficits strongly impede the reading by autistic people on their own and productive mastering by them of the literature course at school age. In order to the work leave a mark in the soul of an autistic person, enrich his ideas about the world of people and about himself , it is necessary to learn a book slowly and to return to it on different occasions and in different contexts. The ways of aid an autistic person in connecting the work content and his own life experience and emotional impressions, in developing possibilities of an empathy, in remembering the content and using it later are described. Then, a matter of choosing appropriate books and films for such a job is discussed. The article describes techniques that help an autistic person to connect the content of a work with his own emotional experience and life experiences. Also it describes abilities which develop the empathy to the characters of a work, the memorization of the work's plot and the actualization of information about a work in the future.

    Full Text Available Interpretation of resistivity cross sections may be in many cases unreliable due to the presence of artifacts left by the inversion process. One way to avoid erroneous conclusions about geological structure is creation of Depth of Investigation (DOI index maps, which describe durability of prepared model with respect to variable parameters of inversion. To assess the usefulness of this interpretation methodology in resistivity imaging method over quaternary sediments, it has been used to one synthetic data set and three investigation sites. Two of the study areas were placed in the Upper Silesian Industrial District region: Bytom - Karb, Chorzów - Chorzow Stary; and one in the Southern Pomeranian Lake District across Piława River Valley. Basing on the available geological information the results show high utility of DOI index in analysis of received resistivity models, on which areas poorly constrained by data has been designated.

    A prototype small animal positron emission tomography (PET) scanner for mouse brain imaging has been developed at UC Davis. The new scanner uses tapered detector arrays with depth of interaction (DOI) measurement. In this paper, we present an efficient system model for the tapered PET scanner using matrix factorization and a virtual scanner geometry. The factored system matrix mainly consists of two components: a sinogram blurring matrix and a geometrical matrix. The geometric matrix is based on a virtual scanner geometry. The sinogram blurring matrix is estimated by matrix factorization. We investigate the performance of different virtual scanner geometries. Both simulation study and real data experiments are performed in the fully 3D mode to study the image quality under different system models. The results indicate that the proposed matrix factorization can maintain image quality while substantially reduce the image reconstruction time and system matrix storage cost. The proposed method can be also applied to other PET scanners with DOI measurement. (paper)

    Phoswich depth-of-interaction (DOI) detectors utilizing multiple scintillators with different decay time are a useful device for developing a high spatial resolution, high sensitivity PET scanner. However, in order to apply pulse shape discrimination (PSD), there are not many combinations of scintillators for which phoswich technique can be implemented. Ce doped Gd_3Ga_3Al_2O_1_2 (GFAG) is a recently developed scintillator with a fast decay time. This scintillator is similar to Ce doped Gd_3Al_2Ga_3O_1_2 (GAGG), which is a promising scintillator for PET detector with high light yield. By stacking these scintillators, it may be possible to realize a high spatial resolution and high timing resolution phoswich DOI detector. Such phoswich DOI detector may be applied to time-of-flight (TOF) systems with high timing performance. Therefore, in this study, we tested the basic performance of the new scintillator –GFAG for use in a TOF phoswich detector. The measured decay time of a GFAG element of 2.9 mmx2.9 mmx10 mm in dimension, which was optically coupled to a photomultiplier tube (PMT), was faster (66 ns) than that of same sized GAGG (103 ns). The energy resolution of the GFAG element was 5.7% FWHM which was slightly worse than that of GAGG with 4.9% FWHM for 662 keV gamma photons without saturation correction. Then we assembled the GFAG and the GAGG crystals in the depth direction to form a 20 mm long phoswich element (GFAG/GAGG). By pulse shape analysis, the two types of scintillators were clearly resolved. Measured timing resolution of a pair of opposing GFAG/GAGG phoswich scintillator coupled to Silicon Photomultipliers (Si-PM) was good with coincidence resolving time of 466 ps FWHM. These results indicate that the GFAG combined with GAGG can be a candidate for TOF-DOI-PET systems.

  5. An inter-crystal scatter correction method for DOI PET image reconstruction

    New positron emission tomography (PET) scanners utilize depth-of-interaction (DOI) information to improve image resolution, particularly at the edge of field-of-view while maintaining high detector sensitivity. However, the inter-crystal scatter (ICS) effect cannot be neglected in DOI scanners due to the use of smaller crystals. ICS is the phenomenon wherein there are multiple scintillations for irradiation of a gamma photon due to Compton scatter in detecting crystals. In the case of ICS, only one scintillation position is approximated for detectors with Anger-type logic calculation. This causes an error in position detection and ICS worsens the image contrast, particularly for smaller hotspots. In this study, we propose to model an ICS probability by using a Monte Carlo simulator. The probability is given as a statistical relationship between the gamma photon first interaction crystal pair and the detected crystal pair. It is then used to improve the system matrix of a statistical image reconstruction algorithm, such as maximum likehood expectation maximization (ML-EM) in order to correct for the position error caused by ICS. We apply the proposed method to simulated data of the jPET-D4, which is a four-layer DOI PET being developed at the National Institute of Radiological Sciences. Our computer simulations show that image contrast is recovered successfully by the proposed method. (author)

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2012v14n4p483This paper aimed to review the results of studies on neuromuscular adaptations to strength training (ST and concurrent training (CT in elderly men. A literature search was conducted using PubMed, Scopus, and SciELO. The search was limited to studies published from 1980 to 2012. A total of 3,390 articles were retrieved. After reading their titles, 127 studies were further evaluated by reading their abstracts. This resulted in 92 papers that were read in full; 25 of these were selected and their results were described in the present review. Several studies showed that, in elderly subjects, ST can produce increases in muscle strength, power, activation and mass. ST-induced strength gain may be explained by neural and morphological adaptations. The main neural adaptations to ST included increased recruitment of motor units and increased motor unit firing rate. Morphological adaptations included increases in the physiological cross-sectional area (CSA of the muscle, in muscle thickness, in muscle fiber pennation angle, and changes in muscle myosin heavy-chain isoforms, resulting in the conversion of muscle fiber from subtype IIx to IIa. The inclusion of moderate-to-high inten- sity (60-85% of maximum strength ST in the routine of this population is recommended to improve neuromuscular function. CT can promote significant neuromuscular adaptations, but these gains may be of a lower magnitude than those obtained with ST. Although CT has an interference effect on neuromuscular adaptations, it also promotes improvement in cardiovascular function and is therefore the most frequently recommended intervention for health promotion in the elderly.

    This study depicts the evaluation of a SiPM detector with depth of interaction (DOI) capability via a dual-sided readout that is suitable for high-resolution positron emission tomography and magnetic resonance (PET/MR) imaging. Two different 12  ×  12 pixelated LSO scintillator arrays with a crystal pitch of 1.60 mm are examined. One array is 20 mm-long with a crystal separation by the specular reflector Vikuiti enhanced specular reflector (ESR), and the other one is 18 mm-long and separated by the diffuse reflector Lumirror E60 (E60). An improvement in energy resolution from 22.6% to 15.5% for the scintillator array with the E60 reflector is achieved by taking a nonlinear light collection correction into account. The results are FWHM energy resolutions of 14.0% and 15.5%, average FWHM DOI resolutions of 2.96 mm and 1.83 mm, and FWHM coincidence resolving times of 1.09 ns and 1.48 ns for the scintillator array with the ESR and that with the E60 reflector, respectively. The measured DOI signal ratios need to be assigned to an interaction depth inside the scintillator crystal. A linear and a nonlinear method, using the intrinsic scintillator radiation from lutetium, are implemented for an easy to apply calibration and are compared to the conventional method, which exploits a setup with an externally collimated radiation beam. The deviation between the DOI functions of the linear or nonlinear method and the conventional method is determined. The resulting average of differences in DOI positions is 0.67 mm and 0.45 mm for the nonlinear calibration method for the scintillator array with the ESR and with the E60 reflector, respectively; Whereas the linear calibration method results in 0.51 mm and 0.32 mm for the scintillator array with the ESR and the E60 reflector, respectively; and is, due to its simplicity, also applicable in assembled detector systems.

    Purpose: Positron emission tomography (PET) detectors that use a dual-ended-scintillator readout to measure depth-of-interaction (DOI) must have an accurate DOI function to provide the relationship between DOI and signal ratios to be used for detector calibration and recalibration. In a previous study, the authors used a novel and simple method to accurately and quickly measure DOI function by irradiating the detector with an external uniform flood source; however, as a practical concern, implementing external uniform flood sources in an assembled PET system is technically challenging and expensive. In the current study, therefore, the authors investigated whether the same method could be used to acquire DOI function from scintillator-generated (i.e., internal) radiation. The authors also developed a method for calibrating the energy scale necessary to select the events within the desired energy window. Methods: The authors measured the DOI function of a PET detector with lutetium yttrium orthosilicate (LYSO) scintillators. Radiation events originating from the scintillators' internal Lu-176 beta decay were used to measure DOI functions which were then compared with those measured from both an external uniform flood source and an electronically collimated external point source. The authors conducted these studies with several scintillators of differing geometries (1.5 x 1.5 and 2.0 x 2.0 mm 2 cross-section area and 20, 30, and 40 mm length) and various surface finishes (mirror-finishing, saw-cut rough, and other finishes in between), and in a prototype array. Results: All measured results using internal and external radiation sources showed excellent agreement in DOI function measurement. The mean difference among DOI values for all scintillators measured from internal and external radiation sources was less than 1.0 mm for different scintillator geometries and various surface finishes. Conclusions: The internal radioactivity of LYSO scintillators can be used to

    We present a preliminary study on the design of a high sensitivity small animal depth of interaction (DOI)-PET scanner: jPET-RD (for Rodents with DOI detectors), which will contribute to molecular imaging. The 4-layer DOI block detector for the jPET-RD that consists of scintillation crystals (1.4 mm x 1.4 mm x 4.5 mm) and a flat panel position-sensitive photomultiplier tube (52 mm x 52 mm) was previously proposed. In this paper, we investigate imaging performance of the jPET-RD through numerical simulations. The scanner has a hexagonal geometry with a small diameter and a large axial aperture. Therefore DOI information is expected to improve resolution uniformity in the whole field of view (FOV). We simulate the scanner for various parameters of the number of DOI channels and the crystal length. Simulated data are reconstructed using the maximum likelihood expectation maximization with accurate system modeling. The trade-off results between background noise and spatial resolution show that only shortening the length of crystal does not improve the trade-off at all, and that 4-layer DOI information improves uniformity of spatial resolution in the whole FOV. Excellent performance of the jPET-RD can be expected based on the numerical simulation results. (author)

    A depth of interaction (DOI) detector is being developed for the brain PET scanner, jPET-D4. We introduce a light output correction procedure to compensate for variations among the crystal elements in the DOI detector. Under uniform irradiation with 511 keV gamma rays, we estimate the light output of each crystal element by identifying each crystal element, and generate a look-up table (LUT) for light output correction. We evaluate the energy resolution of all crystal elements. The energy resolution of 16% is achieved after light output correction for all crystal elements. The DOI detector can correct light output variations that are related to the DOI. We analyze the crystal position dependence of the energy spectra due to inter-crystal scattering among the multiple crystal elements in the DOI detector. It is highly possible that gamma rays interacting with central crystal elements in the crystal array are absorbed by surrounding crystal elements and the Compton part of the energy spectrum is decreased. Inter-crystal scattering has less impact on the energy resolution of the DOI detector

    In a conventional PET scanner, coincidence events are measured with a limited energy window for detection of photoelectric events in order to reject Compton scatter events that occur in a patient, but Compton scatter events caused in detector crystals are also rejected. Scatter events within the patient causes scatter coincidences, but inter crystal scattering (ICS) events have useful information for determining an activity distribution. Some researchers have reported the feasibility of PET scanners based on a Compton camera for tracing ICS into the detector. However, these scanners require expensive semiconductor detectors for high-energy resolution. In the Anger-type block detector, single photons interacting with multiple detectors can be obtained for each interacting position and complete information can be gotten just as for photoelectric events in the single detector. ICS events in the single detector have been used to get coincidence, but single photons interacting with multiple detectors have not been used to get coincidence. In this work, we evaluated effect of sensitivity improvement using Compton kinetics in several types of DOI-PET scanners. The proposed method promises to improve the sensitivity using coincidence events of single photons interacting with multiple detectors, which are identified as the first interaction (FI). FI estimation accuracy can be improved to determine FI validity from the correlation between Compton scatter angles calculated on the coincidence line-of-response. We simulated an animal PET scanner consisting of 42 detectors. Each detector block consists of three types of scintillator crystals (LSO, GSO and GAGG). After the simulation, coincidence events are added as information for several depth-of-interaction (DOI) resolutions. From the simulation results, we concluded the proposed method promises to improve the sensitivity considerably when effective atomic number of a scintillator is low. Also, we showed that FI estimate

    It is critically needed yet challenging to develop compact PET detectors with high sensitivity and uniform, high imaging resolution for improving the performance of simultaneous PET/MR imaging, particularly for an integrated/inserted small-bore system. Using the latest “edge-less” SiPM arrays for DOI measurement using the design of dual-ended-scintillator readout, we developed several compact PET detectors suited for PET/MR imaging. Each detector consists of one LYSO array with each end coupled to a SiPM array. Multiple detectors can be seamlessly tiled together along all sides to form a large detector panel. Detectors with 1.5x1.5 and 2.0x2.0 mm crystals at 20 or 30 mm lengths were studied. Readout of individual SiPM or capacitor-based signal multiplexing was used to transfer 3D interaction position-coded analog signals through flexible-print-circuit cables to dedicated ASIC frontend electronics to output digital timing pulses that encode interaction information. These digital pulses can be transferred to, through standard LVDS cables, and decoded by a FPGA-based data acquisition positioned outside the MRI scanner for coincidence event selection. Initial detector performance measurement shows excellent crystal identification even with 30 mm long crystals, ~18% and 2.8 ns energy and timing resolutions, and around 2-3 mm DOI resolution. A large size detector panel can be scaled up with these modular detectors and different PET systems can be flexibly configured with the scalable readout electronics and data acquisition, providing an important design advantage for different system and application requirements. It is expected that standard shielding of detectors, electronics and signal transfer lines can be applied for simultaneous PET/MR imaging applications, with desired DOI measurement capability to enhance the PET performance and image quality.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2012v14n4p390Physical activity (PA in children has a decisive role in motor development and prevention of childhood obesity. The available evidence suggests that there is high preva­lence of low levels of PA in children, but little is known about the level of PA in preschool children. The objective of this study was to identify the prevalence and the factors associated with low levels of PA in preschool children. This was a cross-sectional study performed in private schools in the municipality of Olinda (state of Pernambuco, with data collection through parent’s face-to-face interviews. The study included 265 children (54.3% girls with mean age of 4.9 years (SD=0.8. Children who did not perform at least 60 minutes/day of outdoors physical activities were considered exposed to low levels of PA. Data analysis was performed by logistic regression considering low level of PA as the outcome. The results showed that 65.3% (95%CI: 9.4-70.8 of children were classified as exposed to ‘low level of PA’. Analysis showed that higher parental education (OR=2.41; 95%CI: 1.13-5.10, lack of space for playing at home (OR=2.36; 95%CI: 1.17- 4.78, and attending school in the afternoon (OR=2.92, 95%CI 1.55-5.49 or full-time (OR=57.1, 95%CI 6.57-496.2 were associated with low levels of PA. Preschoolers from families with higher number of children had lower likelihood of low level of PA (OR=0.49; 95%CI 0.26-0.93. It can be concluded that the proportion of children exposed to low levels of PA is high compared to the results of similar studies and that parental and environmental factors are associated with physical activity level in preschool-aged children.

  1. A novel method to calibrate DOI function of a PET detector with a dual-ended-scintillator readout

    The detection of depth-of-interaction (DOI) is a critical detector capability to improve the PET spatial resolution uniformity across the field-of-view and will significantly enhance, in particular, small bore system performance for brain, breast, and small animal imaging. One promising technique of DOI detection is to use dual-ended-scintillator readout that uses two photon sensors to detect scintillation light from both ends of a scintillator array and estimate DOI based on the ratio of signals (similar to Anger logic). This approach needs a careful DOI function calibration to establish accurate relationship between DOI and signal ratios, and to recalibrate if the detection condition is shifted due to the drift of sensor gain, bias variations, or degraded optical coupling, etc. However, the current calibration method that uses coincident events to locate interaction positions inside a single scintillator crystal has severe drawbacks, such as complicated setup, long and repetitive measurements, and being prone to errors from various possible misalignments among the source and detector components. This method is also not practically suitable to calibrate multiple DOI functions of a crystal array. To solve these problems, a new method has been developed that requires only a uniform flood source to irradiate a crystal array without the need to locate the interaction positions, and calculates DOI functions based solely on the uniform probability distribution of interactions over DOI positions without knowledge or assumption of detector responses. Simulation and experiment have been studied to validate the new method, and the results show that the new method, with a simple setup and one single measurement, can provide consistent and accurate DOI functions for the entire array of multiple scintillator crystals. This will enable an accurate, simple, and practical DOI function calibration for the PET detectors based on the design of dual-ended-scintillator readout. In

    Depth-of-interaction (DOI) information, which improves resolution uniformity in the field of view (FOV), is expected to lead to high-sensitivity PET scanners with small-bore detector rings. We are developing small-bore PET scanners with DOI detectors arranged in hexagonal or overlapped tetragonal patterns for small animal imaging or mammography. It is necessary to optimize the imaging system model because these scanners exhibit irregular detector sampling. In this work, we compared two imaging system models: (a) a parallel sub-LOR model in which the detector response functions (DRFs) are assumed to be uniform along the line of responses (LORs) and (b) a sub-crystal model in which each crystal is divided into a set of smaller volumes. These two models were applied to the overlapped tetragonal scanner (FOV 38.1 mm in diameter) and the hexagonal scanner (FOV 85.2 mm in diameter) simulated by GATE. We showed that the resolution non-uniformity of system model (b) was improved by 40% compared with that of system model (a) in the overlapped tetragonal scanner and that the resolution non-uniformity of system model (a) was improved by 18% compared with that of system model (b) in the hexagonal scanner. These results indicate that system model (b) should be applied to the overlapped tetragonal scanner and system model (a) should be applied to the hexagonal scanner. (author)

    Depth-of-interaction (DOI) detectors are considered to be advantageous for time-of-flight positron emission tomography (TOF-PET) because they can correct timing errors arising in the scintillation crystals due to a propagation speed difference between annihilation radiation and scintillation photons. We experimentally measured this timing error, using our four-layer DOI encoding method. The upper layers exhibited the larger timing delays due to the longer path lengths after conversion from annihilation radiation into scintillation photons that traveled by zigzag paths at a speed decreased by a factor of the refractive index (n). The maximum timing delay between the uppermost and the lowermost layers was evaluated as 164 ps when n=1.47. A TOF error correction was demonstrated to improve the timing resolution of the four-layer DOI detector by 10.3%, which would increase the effective sensitivity of the scanner by about 12% comparison with a non-DOI TOF-PET scanner. This is the first step towards combining these two important fields in PET instrumentation, namely DOI and TOF, for the purpose of achieving a higher sensitivity as well as a more uniform spatial resolution.

    Department of Energy and Defense Programs systems are becoming increasingly reliant on the use of optical technologies that must perform under a range of ionizing radiation environments. In particular, the radiation response of materials under consideration for applications in direct optical initiation (D.O.I.) schemes must be well characterized. In this report, transient radiation effects observed in Schott filter glass S-7010 are characterized. Under gamma exposure with 2 MeV photons in a 20--30 nsec pulse, the authors observe strong initial induced fluorescence in the red region of the spectrum followed by significant induced absorption over the same spectral region. Peak induced absorption coefficients of 0.113 cm -1 and 0.088 cm -1 were calculated at 800 nm and 660 nm respectively

    We developed a depth of interaction (DOI) positron emission tomography (PET) detector using depth-dependent reflector patterns in a discrete crystal array. Due to the different reflector patterns at depth, light distribution was changed relative to depth. As a preliminary experiment, we measured DOI detector module crystal identification performance. The crystal consisted of a 9×9 array of 2 mmx2 mmx20 mm lutetium-yttrium oxyorthosilicate (LYSO) crystals. The crystal array was optically coupled to a 64-channel position-sensitive photomultiplier tube with a 2 mmx2 mm anode size and an 18.1 mmx18.1 mm effective area. We obtained the flood image with an Anger-type calculation. DOI layers and 9×9 pixels were well distinguished in the obtained images. Preclinical PET scanners based on this detector design offer the prospect of high and uniform spatial resolution.

  20. Enhanced defect of interest [DOI] monitoring by utilizing sensitive inspection and ADRTrue SEM review

    As semiconductor process design rules continue to shrink, the ability of optical inspection tools to separate between true defects and nuisance becomes more and more difficult. Therefore, monitoring Defect of Interest (DOI) become a real challenge (Figure 1). This phenomenon occurs due to the lower signal received from real defects while noise levels remain almost the same, resulting in inspection high nuisance rate, which jeopardizes the ability to provide a meaningful, true defect Pareto. A non-representative defect Pareto creates a real challenge to a reliable process monitoring (Figure 4). Traditionally, inspection tool recipes were optimized to keep data load at a manageable level and provide defect maps with ~10% nuisance rate, but as defects of interest get smaller with design rule shrinkage, this requirement results in a painful compromise in detection sensitivity. The inspection is usually followed by defect review and classification using scanning electron microscope (SEM), the classification done manually and it is performed on a small sample of the inspection defect map due to time and manual resources limitations. Sample is usually 50~60 randomly selected locations, review is performed manually most of the times, and manual classification is performed for all the reviewed locations. In the approach described in this paper, the inspection tool recipe is optimized for sensitivity rather than low nuisance rate (i.e. detect all DOI with compromising on a higher nuisance rate). Inspection results with high nuisance rate introduce new challenges for SEM review methodology & tools. This paper describe a new approach which enhances process monitoring quality and the results of collaborative work of the Process Diagnostic & Control Business Unit of Applied Materials® and GLOBALFOUNDRIES® utilizing Applied Materials ADRTrueTM & SEMVisionTM capabilities. The study shows that the new approach reveals new defect types in the Pareto, and improves the ability to

  1. A High Resolution Monolithic Crystal, DOI, MR Compatible, PET Detector. Final-Report

    International Nuclear Information System (INIS)

    Miyaoka, Robert S.

    2012-01-01

    The principle objective of this proposal is to develop a positron emission tomography (PET) detector with depth-of-interaction (DOI) positioning capability that will achieve state of the art spatial resolution and sensitivity performance for small animal PET imaging. When arranged in a ring or box detector geometry, the proposed detector module will support 15% absolute detection efficiency. The detector will also be compatible with operation in a MR scanner to support simultaneous multi-modality imaging. The detector design will utilize a thick, monolithic crystal scintillator readout by a two-dimensional array of silicon photomultiplier (SiPM) devices using a novel sensor on the entrance surface (SES) design. Our hypothesis is that our single-ended readout SES design will provide an effective DOI positioning performance equivalent to more expensive dual-ended readout techniques and at a significantly lower cost. Our monolithic crystal design will also lead to a significantly lower cost system. It is our goal to design a detector with state of the art performance but at a price point that is affordable so the technology can be disseminated to many laboratories. A second hypothesis is that using SiPM arrays, the detector will be able to operate in a MR scanner without any degradation in performance to support simultaneous PET/MR imaging. Having a co-registered MR image will assist in radiotracer localization and may also be used for partial volume corrections to improve radiotracer uptake quantitation. The far reaching goal of this research is to develop technology for medical research that will lead to improvements in human health care.

    We have built a four-layer detector to obtain depth of interaction (DOI) information in which all four layers have a relative offset of half a crystal pitch with each other. The main characteristics of the detector, especially the energy and spatial resolutions, strongly depend on the crystal surface treatments. As a part of the development of an animal PET, we have investigated the effect of crystal surface treatment on detector performances using Monte Carlo simulations in order to optimize the surface conditions of crystals composing a four-layer detector. The proposed detector consists of four LYSO layers with crystal dimensions of 1.5x1.5x7.0 and 1.5x1.5x5.0 mm 3 . A simulation tool (DETECT2000) was used and validated against the experimental results; flood images were acquired by a prototype module. Flood images were simulated by varying the surface treatment of the crystals. The optimal surface conditions of the four-layer crystals were derived for a small animal PET with a view towards achieving high sensitivity, as well as high and uniform radial resolution.

    Tourette syndrome (TS) is a neurological disorder characterized by highest familial recurrence rate among neuropsychiatric diseases with complicated inheritance. Recurrence of Tourette syndrome was frequently observed in clinical. Unexpectedly, the mechanism of recurrence of Tourette syndrome was failure to elucidate. Here, we first shown that lipopolysaccharide(LPS) may played an important role in the recurrence of Tourette syndrome. The TS model in rats was induced by DOI (the selective 5-HT2A/2C agonist 1-(2, 5-dimethoxy-4-iodophenyl) -2- aminopropane). The rats were randomly divided into 4 groups:(1)Control;(2) Control + LPS; (2)TS; (3)TS + LPS. The results demonstrated that the LPS treatment significantly increased stereotypic score and autonomic activity. LPS treatment also significantly increased inflammatory cytokines such as interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in serum and striatum. Also, highly expressed TLR4, MyD88, P-NF-κBp65, P-IκBα in TS rats were increased respectively by LPS treatment as indicted in western blot analysis and immunohistochemistry analysis. Thus, it was supposed that lipopolysaccharide(LPS) may played an important role in the recurrence of Tourette syndrome and its mechanism was related to TLR/NF-κB pathway.

    Silicon Photomultiplier (SiPM) is a promising sensor for MR-compatible PET systems. In this paper, we developed a compact 2-layer DOI-PET detector. The top layer is a 15×15 LYSO array, and the crystal size is 2x2x7mm{sup 3}. The bottom layer is a 16×16 array with the same size crystals. There is half-crystal offset between two layers in both transverse directions. The detector is coupled to an 8×8 SiPM array (MicroFB-30035-SMT, Sensl). Sixty-four channels of SiPMs are read out by an ASIC chip with in-chip multiplexing resistor networks in the form of two position and one energy analog signals, and are then converted to wave-form digital signals with 80 MHz 12-bit ADC chips. The energy is calculated by averaging the 3 points around the peak of the pulse. Flood images with two 22Na point sources irradiated on the top and at the bottom of the detector module were acquired. The results show that the detector module achieves good crystal identification capability in both layers with an average energy resolution of 17.1% at 511 keV.

    Full Text Available Este artigo propõe realizar uma leitura de dois artistas considerados modernos: o uruguaio Joaquín Torres-García e o português Amadeo de Souza-Cardoso. O ponto de partida desta reflexão é o verbete “Informe” de Georges Bataille, publicado no ano de 1929 no Dicionário crítico da revista Documents (1929-1931. Trazemos para a discussão a leitura realizada por Rosalind Krauss e Yve-Alain Bois, por ocasião da exposição L’informe. Mode d’emploi, em que o verbete batailleano é transformado em operação de caráter performativo. Partindo desses teóricos, pretende-se investigar os possíveis desdobramentos de alguns conceitos caros à modernidade, que circulam em torno do esgotamento das vanguardas e se elaboram em processo simultâneo aos próprios movimentos. Além dos trabalhos de Krauss e Bois, alguns textos críticos a respeito de outras obras de Bataille e também sobre a teoria da modernidade servem de referência, ao longo desse ensaio, para contrapor e apresentar as singularidades de duas produções artísticas.

    Full Text Available A influência da Trifluralina 600 CE sobre a atividade microbiana e taxa de liberação de CO2 foi estudada com amostras de solos da Unidade de Mapeamento São Pedro e Cruz Alta, incubados a 80% da capacidade de campo ou saturados, com tratamentos equivalendo a 2 e 4 litros por hectare, com cinco repetições, durante 140 dias. A cada sete dias foram efetuadas titulações de CO2 liberado. Posteriormente foi executado bioensaio com Sorghum bicolor L. Moench para análise da persistência do produto no solo. O herbicida nas dosagens usadas não afetou a atividade microbiana. A persistência do herbicida mostrou diferença significativa entre plântulas anormais para os dois solos em capacidade de campo, o mesmo não ocorrendo quando a germinação foi em solos saturados.

RELATO DOS CASOS: O primeiro é uma paciente de 22 anos de idade com quadro súbito de disartria e déficit motor em dimídio esquerdo. Ao exame clínico, apresentava taquicardia, exoftalmia bilateral e bócio difuso. Referia tratamento para hipertiroidismo há um mês. O segundo é uma paciente de 15 anos de idade, que apresentou quadro súbito de perda da consciência seguindo-se distúrbio de linguagem e déficit motor em hemicorpo direito. RESULTADOS: Os exames de imagem revelaram áreas de lesão cerebral sugestivas de isquemia. Os estudos angiográficos cerebrais evidenciaram estenoses vasculares múltiplas compatíveis com arterite. Foram descartadas outras causas possíveis de vasculite cerebral. Os exames laboratoriais revelaram hipertiroidismo e presença dos anticorpos antimicrossomais e antitireoglobulina. As duas pacientes receberam tratamento para o hipertiroidismo. CONCLUSÃO: A associação entre arterite cerebral e doença de Basedow-Graves sugere que possa existir um elo na patogenia das duas doenças através de mecanismo auto-imune comum a ambas.

    The best-characterized 5HT 2 radioligands, such as [ 3 H]ketanserin and [ 3 H]spiperone, are antagonists that label both high- and low-affinity states of this receptor. Recently, the radiolabeled phenylisopropylamine hallucinogens DOB and DOI, which are agonists at 5HT 2 receptors, have been demonstrated to label selectively the high-affinity state of brain 5HT 2 receptors. In the present study, the authors determined optimum conditions for autoradiographic visualization of [ 125 I]DOI binding and characterized its pharmacology and guanine nucleotide sensitivity under those conditions. In slide-mounted tissue sections (rat forebrain; two 10 μm sections/slide), (±)[ 125 I]DOI binding was saturable, of high affinity (K D ∼4nM) and displayed a pharmacological profile [R(-)DOI > spiperone > DOB > (±)DOI > ketanserin > S(+)DOI > 5HT > DOM] comparable to that seen in homogenate assays. Consistent with coupling of 5HT 2 receptors to a guanine nucleotide regulatory protein, [ 125 I]DOI binding was inhibited by guanine nucleotides but not by ATP. In autoradiograms, high densities of [ 125 I]DOI binding sites were present in frontal cortex, olfactory tubercle, claustrum, caudate/putamen and mamillary nuclei with lower densities in trigeminal and solitary nuclei. The highest density of [ 125 l]DOI binding was observed in choroid plexus; these binding sites displayed a pharmacological profile characteristic of 5HT 1C receptors. These data suggest that [ 125 I]DOI labels both 5HT 2 and 5HT 1C receptors

  9. In-situ monitoring of undercoating corrosion damage by Direct Optical Interrogation (DOI)

    Science.gov (United States)

    Lopez-Garrity, Meng

    An approach referred to as "Direct Optical Interrogation" (DOI) has been developed as an extension of the thin film pitting approach developed and used by Frankel and others. Samples were prepared by depositing Al and Al-Cu alloy metallizations about 800 nm thick on glass substrates. These metallizations were then coated with various coatings and coating systems. Samples were introduced to aggressive environments and the progression of corrosion of the metallization under the coating was monitored in situ using low power videography. Because metallizations were thin, corrosion quickly penetrated through the metal layer to the glass substrate and then spread laterally. Measurement of the lateral spread of corrosion enabled non-electrochemical assessment of the corrosion kinetics. In Al-Cu thin films, both aged and as-deposited, corrosion sites are irregularly shaped because there is not enough cathodic current to propagate the entire corrosion site margin at equal rates. In a number of cases, corrosion propagates with a filamentary morphology resembling filiform corrosion. Cu played a strong role in determining under coating corrosion morphology and growth kinetics in experiments with Al-Cu thin films substrates. As-deposited Al-Cu metallizations were more corrosion resistant than aged metallization and both were more corrosion resistant than pure Al. Cu-rich dendrites were formed on the corrosion front. Corrosion rate (current density) was calculated using Faraday's law by collecting corrosion site perimeter and bottom area. Systematic exploration of the effects of a chromate and chromate-free conversion coatings, chromate and chromate-free primer coatings and the presence or absence of a polyurethane topcoat confirmed the extraordinary corrosion protection by chromates. A commercial praseodymium-pigmented primer coating was not particularly effective in retarding undercoating corrosion site growth unless paired with a chromate conversion coating. The presence of a

Este trabalho relata dois casos recentes deste tipo de tumor, envolvendo tanto a pálpebra superior quanto a inferior em duas mulheres. O primeiro caso é de uma mulher de 72 anos de idade, amaurótica do olho direito, com comprometimento de aproximadamente 80% da pálpebra superior esquerda, 70% da pálpebra inferior esquerda e comprometimento da parede lateral da órbita, comprovado pela tomografia computadorizada. O exame anatomopatológico da peça cirúrgica revelou a presença de carcinoma basocelular invasivo, com margens livres. Foi feita reconstrução imediata com retalho de Fricke. O segundo caso é de senhora de 68 anos de idade, com história prévia de trauma na região periorbitária esquerda, apresentando edema e hiperemia palpebral, com aspecto brilhante, com perda dos cílios e pequena ulceração central, envolvendo aproximadamente 90% da pálpebra superior e 65% da pálpebra inferior esquerda, com comprometimento da parede lateral da órbita evidenciado na tomografia. O exame anatomopatológico da peça cirúrgica revelou a presença de carcinoma basocelular invasivo, com margens livres. Foi optado pela reconstrução imediata com retalho de Fricke. Os autores acreditam que apesar deste tipo de retalho não ser a primeira escolha na maioria das reconstruções palpebrais, não deveria ser negligenciado, pois em certos casos, tornar-se-ia a única opção viável.

    Full Text Available The edaphoclimatic conditions in Southwest Parana differ from those in traditional wine-growing regions and have a major influence on the organoleptic characteristics of the grapes. Studies of grape maturation under these conditions may enable us to time the supply of raw materials for the elaboration of differentiated wines. This study aimed to quantify the ripening components of the grape cultivars Cabernet Sauvignon, Merlot, Tempranillo, and Sangiovese grapes grown in Dois Vizinhos, PR, during the harvest seasons of 2008/2009 and 2011/2012. The grapevines were performed according to the espalier system and grafted on rootstock R110 (‘Cabernet Sauvignon’ and ‘Merlot’ and Paulsen 1103 (‘Tempranillo’ and ‘Sangiovese’. The ripening of the grapes was monitored every ten days from the beginning of ripening (verasion until harvest. The following variables were evaluated: mass and diameter of berries, total soluble solids (TSS, pH, titratable acidity (TTA, total sugars, estimated alcohol content, anthocyanins, and flavanols. Sangiovese berries showed the greatest weight and diameter in the two years. The TSS was higher in the second year of evaluation for Cabernet Sauvignon and Tempranillo grapes. The pH decreased from the first year to the second for all cultivars. There were no significant differences in ATT among the cultivars. A higher content of flavanols was observed during the first growing season of study than during the second. Tempranillo grapes showed the highest concentration of anthocyanins during both growing seasons. Not all cultivars had enough acidity to permit wine stability and guard time. None of the cultivars required the chaptalization of must, presenting good potential of alcohol production.

    The purpose of this study was to evaluate the efficacy of fluoroscopy time/total exposure times exposure times · in direction of interest (F/E·DOI) method as an approximate estimate of skin dose during percutaneous coronary intervention (PCI) procedure. Up to March 10, 2004, fifty-seven patients (male: 46 cases, female: 11 cases, age range 38-85 years; mean age 67±11 years) had undergone PCI and 157 directions of exposure was measured using X-ray films (KONICA MINOLTA SR-DUP) placed under the back of each patient during the procedure. The fluoroscopy time (minutes), the times of exposure in each direction during the procedure, and the thickness of chest (cm) was recorded. The relation of the skin dose to fluoroscopic time, exposure times in direction of interest, and F/E·DOI was assessed. The relationship between fluoroscopy time and skin dose was shown as y=0.02x+0.22 (r=0.54, p<0.0001, m.e=0.00±0.71 Gy, e.a=-2.19∼l.53 Gy). In addition, the relation of skin dose to exposure times in the direction of interest was y=0.07x+0.27 (r=0.77, p<0.0001, m.e=-0.00±0.53 Gy, e.a=-2.45∼1.76 Gy). The relationship between skin dose and F/E·DOI was y=0.06x+0.30 (r=0.85, p<0.0001, m.e=-0.00±0.44 Gy, e.a=-1.28∼1.06 Gy). Moreover, the relationship between skin dose and (F/E·DOI x 0.06+0.30) x coefficient of direction x coefficient in thickness of chest was y=0.99x-0.02 (r=0.89, p<0.0001, m.e=0.00±0.38 Gy, e.a=-1.12∼l.27 Gy). The calculated results corresponded to the skin dose during the procedure. F/E·DOI method was simple and effective, moreover, that enabled us to inform the skin dose during the PCI procedure to the interventionalist easily. (authors)

    Full Text Available We describe two cases of palatal myoclonus (PM, one essential and another secondary to a stroke. Case 1: a 64 years old female who developed clicking sounds in both ears after a stroke and three years later on noticed a progressive involuntary movement of the throat associated with rhythmic contractions of the soft palate, muscles of tongue and throat. MRI showed an ischemic area in brainstem. The patient had a partial response to the use of sumatriptan 6 mg subcutaneously. Case 2: a 66 years old female who began with ear clicking at left ear that worsed slowly associated with tinnitus and arrhythmic movements of soft palate and an audible click at left ear. Brain MRI was normal; audiometry showed bilateral neurosensory loss. She was prescribed clonazepan 1 mg daily with complete recovery. Primary and secondary palatal myoclonus share the same clinical features but probably have different pathophysiological underlying mechanisms.Descrevemos dois casos de mioclonia palatal (MP, um essencial e o outro secundário a acidente vascular cerebral (AVC. Caso1: mulher de 64 anos que desenvolveu cliques audíveis em ambos os ouvidos após um AVC e que três anos depois começou a apresentar movimentos involuntários do pálato, músculos do língua e garganta. A ressonância magnética (RNM mostrou áreas de isquemia no tronco cerebral. A paciente apresentou resposta parcial e não duradoura ao uso subcutâneo de 6 mg de sumatriptano. Caso 2: mulher de 66 anos, com cliques audíveis no ouvido esquerdo que pioraram progressiva e lentamente associados com tinitus e movimentos mais ou menos rítmicos do pálato mole. A RNM encefálica era normal. A audiometria mostrou perda neurossensorial bilateral. Foi medicada com 1,0 mg de clonazepan diariamente com completa recuperação. MP primária e secundária compartilham das mesmas características clínicas, mas evidências sugerem que se devam a diferentes mecanismos fisiopatológicos.

    Full Text Available Relatam-se dois casos adicionais de linfangiectasia intestinal e linfangite lipogranulomatosa (LI/LL em caninos. Sinais clínicos manifestados pelos animais afetados incluíam diarréia crônica, perda de peso, dificuldade respiratória e anorexia. À necropsia, a mucosa do intestino delgado apresentava-se pálida, macia e com aspecto aveludado mais evidente conferido por vilosidades esbranquiçadas, alongadas, mais visíveis e densamente aglomeradas formando tufos. Na borda mesentérica da serosa intestinal, havia lesões arredondadas, lisas, elevadas, firmes, brancacentas, de 1-3mm de diâmetro, que também acompanhavam os vasos linfáticos mesentéricos que estavam salientes e distendidos por material espesso e esbranquiçado. Carcaças em mau estado corporal, edema subcutâneo e efusões cavitárias também foram observados. Microscopicamente, havia acentuada ectasia dos vasos quilíferos das vilosidades intestinais associada à presença de lipogranulomas intramurais ou mesentéricos. No presente estudo, o diagnóstico definitivo de LI/LL foi realizado através do exame histológico do intestino delgado e mesentério associado. Desconhece-se a prevalência dessa enfermidade em caninos no Brasil.Two additional cases of intestinal lymphangiectasia with lipogranulomatous lymphangitis (IL/LL in dogs are described. Clinical signs in the affected animals included chronic diarrhea, weight loss, labored breathing and anorexia.

A uma revisão bibliográfica focada na compreensão histórica do compromisso social do empresário e na correspondente construção discursiva da instância do poder para legitimação deste papel, segue-se uma aplicação de análise do discurso, por meio da qual se procurou indícios da reprodução desta forma peculiar de discurso organizacional em duas publicações de grande circulação, ao longo de mais de dois anos. Os 38 discursos construídos pelos porta-vozes de alguns dos maiores grupos empresariais brasileiros e por formadores de opinião no meio empresarial trazem fortes indicativos de que a construção discursiva da RSE vem se configurando como fundamental para este processo de legitimação.   Palavras-chave: Análise de Discurso, Discursos Organizacionais, Responsabilidade Social Empresarial.   Abstract The purpose of this paper is to identify and discuss the power´s relations between social actions implemented by private organizations within Corporate Social Responsibility and the attribution legitimate process to the businessman´s social role. Grounded in the Structuralism Theory, developed by Anthony Giddens, this study relied upon the discourse analysis method and spotlighted the organizational discourses published on two business publications.   Key Words: Corporate Social Responsibility, Discourse Analysis, Organizational Discourse.

    Full Text Available O edema pulmonar neurogênico é rara e grave complicação de pacientes com traumatismo craniencefálico (TCE. Pode ocorrer também em outras patologias do sistema nervoso central, tais como acidentes vasculares cerebrais (AVC, tumores ou após crises epilépticas, entre outras. Foram avaliados 36 casos com TCE grave e quatro pacientes com AVC, internados na UTI geral, no período de janeiro a setembro 1995. Nesse intervalo de tempo foram diagnosticados dois casos de edema pulmonar neurogênico, um ocorrendo em paciente com TCE grave e outro em paciente com AVC hemorrágico. O diagnóstico foi estabelecido pelo rápido desenvolvimento de edema pulmonar, com hipoxemia grave, queda da complacência pulmonar e infiltrados difusos bilaterais sem história prévia de aspiração traqueal ou outro fator de risco para o desenvolvimento de síndrome de angústia respiratória aguda. No primeiro paciente com trauma craniencefálico, o edema neurogênico foi diagnosticado na internação, uma hora após o trauma, com concomitante reação inflamatória grave e boa evolução em três dias. O outro caso, com AVC hemorrágico, desenvolveu edema neurogênico no quarto dia após drenagem de hematoma intraparenquimatoso, evoluindo para o óbito.Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal

  17. Four-layer DOI PET detectors using a multi-pixel photon counter array and the light sharing method

    Silicon photomultipliers (SiPMs) provide many advantages for PET detectors, such as their high internal gain, high photon detection efficiency and insensitivity to magnetic fields. The number of detectable scintillation photons of SiPMs, however, is limited by the number of microcells. Therefore, pulse height of PET detectors using SiPMs is saturated when large numbers of scintillation photons enter the SiPM pixels. On the other hand, we previously presented a depth-of-interaction (DOI) encoding method that is based on the light sharing method. Since our encoding method detects scintillation photons with multiple readout pixels, the saturation effect can be suppressed. We constructed two prototype four-layer DOI detectors using a SiPM array and evaluated their performances. The two prototype detectors consisted of four layers of a 6×6 array of Lu 2(1−x) Y 2x SiO 5 (LYSO) crystals and a SiPM (multi-pixel photon detector, MPPC, Hamamatsu Photonics K.K.) array of 4×4 pixels. The size of each LYSO crystal element was 1.46 mm×1.46 mm×4.5 mm and all surfaces of the crystal elements were chemically etched. We used two types of MPPCs. The first one had 3600 microcells and high photon detection efficiency (PDE). The other one had 14,400 microcells and lower PDE. In the evaluation experiment, all the crystals of the detector using the MPPC which had the high PDE were clearly identified. The respective energy and timing resolutions of lower than 15% and 1.0 ns were achieved for each crystal element. No saturation of output signals was observed in the 511 keV energy region due to suppression of the saturation effect by detecting scintillation photons with several MPPC pixels by the light sharing method. -- Highlights: •We constructed and evaluated four-layer DOI detectors by the light sharing method using a MPPC array. •The detectors using two types of the MPPC array were compared. •The energy and timing resolutions of lower than 15% and 1.0 ns were achieved for

    We have developed a four-layer depth of interaction (DOI) detector with single-side photon readout, in which segmented crystals with the patterned reflector insertion are separately identified by the Anger-type calculation. Optical conditions between segmented crystals, where there is no reflector, affect crystal identification ability. Our objective of this work was to improve crystal identification performance of the four-layer DOI detector that uses crystals segmented with a recently developed laser processing technique to include laser processed boundaries (LPBs). The detector consisted of 2 × 2 × 4mm3 LYSO crystals and a 4 × 4 array multianode photomultiplier tube (PMT) with 4.5 mm anode pitch. The 2D position map of the detector was calculated by the Anger calculation method. At first, influence of optical condition on crystal identification was evaluated for a one-layer detector consisting of a 2 × 2 crystal array with three different optical conditions between the crystals: crystals stuck together using room temperature vulcanized (RTV) rubber, crystals with air coupling and segmented crystals with LPBs. The crystal array with LPBs gave the shortest distance between crystal responses in the 2D position map compared with the crystal array coupled with RTV rubber or air due to the great amount of cross-talk between segmented crystals with LPBs. These results were used to find optical conditions offering the optimum distance between crystal responses in the 2D position map for the four-layer DOI detector. Crystal identification performance for the four-layer DOI detector consisting of an 8 × 8 array of crystals segmented with LPBs was examined and it was not acceptable for the crystals in the first layer. The crystal identification was improved for the first layer by changing the optical conditions between all 2 × 2 crystal arrays of the first layer to RTV coupling. More improvement was observed by combining different optical conditions between all

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2012v14n4p428Exhaustive running at maximal oxygen uptake velocity (vVO2max can alter running kinematic parameters and increase energy cost along the time. The aims of the present study were to compare characteristics of ankle and knee kinematics during running at vVO2max and to verify the relationship between changes in kinematic variables and time limit (Tlim. Eleven male volunteers, recreational players of team sports, performed an incremental running test until volitional exhaustion to determine vVO2max and a constant velocity test at vVO2max. Subjects were filmed continuously from the left sagittal plane at 210 Hz for further kinematic analysis. The maximal plantar flexion during swing (p<0.01 was the only variable that increased significantly from beginning to end of the run. Increase in ankle angle at contact was the only variable related to Tlim (r=0.64; p=0.035 and explained 34% of the performance in the test. These findings suggest that the individuals under study maintained a stable running style at vVO2max and that increase in plantar flexion explained the performance in this test when it was applied in non-runners.

    Full Text Available O retinoblastoma pode acometer um ou os dois olhos, ocorrendo de forma hereditária ou esporádica. O portador dessa doença pode desenvolver, a longo prazo, outros tipos de tumores não oculares. Relatamos dois pacientes: o filho, portador de cavidade anoftálmica bilateral após remoção dos olhos devido ao retinoblastoma, que apresentou segundo tumor palpebral unilateral, afetando a pálpebra superior; e o pai, portador de cavidade anoftálmica unilateral também por remoção de retinoblastoma e que apresentou tumoração de crescimento rápido na pálpebra superior ipsilateral ao olho enucleado. O exame imuno-histoquímico de ambas as lesões excisadas revelou que se tratava de carcinoma de glândulas sebáceas. Os pacientes evoluíram bem após a remoção do tumor palpebral e, até o momento, não apresentam sinais de recidiva ou metástase.

    Full Text Available Este artigo tem por objectivo procurar compreender o impacto da estrutura organizacional de dois hospitais públicos portugueses, com diferentes figuras jurídicas, na execução dos seus objectivos, através da percepção dos seus colaboradores. Pretendemos dar um contributo sobre como os gestores dos hospitais podem controlar e modificar a estrutura e o desenho da organização e de que forma essas modificações podem vir a influenciar a execução dos seus objectivos. Assim, recorremos à metodologia do estudo de caso, através do questionário como principal instrumento de recolha de dados, efectuado a 612 colaboradores de ambos os hospitais. Para além de não terem sido encontradas diferenças significativas na estrutura organizacional, entre os dois hospitais, este estudo permite-nos concluir, que o tipo de estrutura organizacional adoptado tem impacto na execução dos objectivos de uma organização, não sendo, no entanto, o único factor que afecta a sua execução.

    In the development of a dedicated small-bore DOI-PET scanner for small animals (jPET-RD), we performed Monte Carlo simulations using the GATE based on Geant4 and investigated the influence of the proximity of the detectors to the target object on the sensitivity and count rate performance. The jPET-RD is based on a large-size depth-of-interaction (DOI) block detector that consists of a 4-layered array of 32 x 32 LSO crystals (1.4 mm x 1.4 mm x 4.5 mm) and a 256-ch flat panel position-sensitive photomultiplier tube. In this work, three detector geometries were simulated: two rings of six detector blocks arranged in a hexagonal pattern (FOV 85 mm in diameter) and four detector blocks arranged in a tetragonal pattern (FOV 49 mm in diameter) and in an overlapped tetragonal pattern (FOV 38 mm in diameter). The simulation results showed that the smaller bore geometry can provide higher sensitivity because of its larger solid angle. Although it clearly affected the noise equivalent count rate (NECR) due to its high dead-time, parallel readout with appropriate anode segmentation improved the NECR at 20 MBq by a factor of 1.1 to 1.4 compared with the case of 256-ch anodes read out by one front-end circuit.

    After decades of social stigma, hallucinogens have reappeared in the clinical literature demonstrating unique benefits in medicine. The precise behavioral pharmacology of these compounds remains unclear, however. Two commonly studied hallucinogens, (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and lysergic acid diethylamide (LSD), were investigated both in vivo and in vitro to determine the pharmacology of their behavioral effects in an animal model. Rabbits were administered DOI or LSD and observed for head bob behavior after chronic drug treatment or after pretreatment with antagonist ligands. The receptor binding characteristics of DOI and LSD were studied in vitro in frontocortical homogenates from naïve rabbits or ex vivo in animals receiving an acute drug injection. Both DOI- and LSD-elicited head bobs required serotonin(2A) (5-HT(2A)) and dopamine(1) (D(1)) receptor activation. Serotonin(2B/2C) receptors were not implicated in these behaviors. In vitro studies demonstrated that LSD and the 5-HT(2A/2C) receptor antagonist, ritanserin, bound frontocortical 5-HT(2A) receptors in a pseudo-irreversible manner. In contrast, DOI and the 5-HT(2A/2C) receptor antagonist, ketanserin, bound reversibly. These binding properties were reflected in ex vivo binding studies. The two hallucinogens also differed in that LSD showed modest D(1) receptor binding affinity whereas DOI had negligible binding affinity at this receptor. Although DOI and LSD differed in their receptor binding properties, activation of 5-HT(2A) and D(1) receptors was a common mechanism for eliciting head bob behavior. These findings implicate these two receptors in the mechanism of action of hallucinogens. Copyright © 2011 Elsevier Inc. All rights reserved.

    We are developing a small animal PET scanner, 'jPET-RD' to achieve high sensitivity as well as high spatial resolution by using four-layer depth-of-interaction (DOI) detectors. The jPET-RD is designed with two detector rings. Each detector ring is composed of six DOI detectors arranged hexagonally. The diameter of the field-of-view (FOV) is 8.8 cm, which is smaller than typical small animal PET scanners on the market now. Each detector module consists of a crystal block and a 256-channel flat panel position-sensitive photomultiplier tube. The crystal block, consisting of 32x32x4 crystal (4096 crystals, each 1.46 mmx1.46 mmx4.5 mm) and a reflector, is mounted on the 256ch FP-PMT. In this study, we evaluated the spatial resolution of reconstructed images with the evaluation system of two four-layer DOI detectors which consist of 32x32x4 LYSO (Lu: 98%, Y: 2%) crystals coupled on the 256ch FP-PMT by using RTV rubber. The spatial resolution of 1.5 mm was obtained at the center of the FOV by the filtered back projection. The spatial resolution, better than 2 mm in the whole FOV, was also achieved with DOI while the spatial resolution without DOI was degraded to 3.3 mm

    The optimization of a whole-body PET system remains a challenging task, as the imaging performance is influenced by a complex interaction of different design parameters. However, it is not always clear which parameters have the largest impact on image quality and are most eligible for optimization. To determine this, we need to be able to assess their influence on image quality. We performed Monte-Carlo simulations of a whole-body PET scanner to predict the influence on image quality of three detector parameters: the TOF resolution, the transverse pixel size and depth-of-interaction (DOI)-correction. The inner diameter of the PET scanner was 65 cm, small enough to allow physical integration into a simultaneous PET-MR system. Point sources were used to evaluate the influence of transverse pixel size and DOI-correction on spatial resolution as function of radial distance. To evaluate the influence on contrast recovery and pixel noise a cylindrical phantom of 35 cm diameter was used, representing a large patient. The phantom contained multiple hot lesions with 5 mm diameter. These lesions were placed at radial distances of 50, 100 and 150 mm from the center of the field-of-view, to be able to study the effects at different radial positions. The non-prewhitening (NPW) observer was used for objective analysis of the detectability of the hot lesions in the cylindrical phantom. Based on this analysis the NPW-SNR was used to quantify the relative improvements in image quality due to changes of the variable detector parameters. The image quality of a whole-body PET scanner can be improved significantly by reducing the transverse pixel size from 4 to 2.6 mm and improving the TOF resolution from 600 to 400 ps and further from 400 to 200 ps. Compared to pixel size, the TOF resolution has the larger potential to increase image quality for the simulated phantom. The introduction of two layer DOI-correction only leads to a modest improvement for the spheres at radial

    Full Text Available Relato de casos de ocorrência de Artrite Idiopática Juvenil (AIJ em dois pares de irmãos acompanhados no serviço de reumatologia pediátrica da Universidade Federal da Bahia. O envolvimento genético na patogênese da AIJ está claro e o risco de recorrência entre irmãos corrobora esta contribuição. Um importante marco dessa descoberta envolve a confirmação da contribuição dos polimorfismos do complexo principal de histocompatibilidade (MHC na susceptibilidade ao desenvolvimento da AIJ. Apesar de muitos progressos, os inúmeros estudos existentes ainda não são capazes de explicar diversos mecanismos implícitos na patogênese da AIJ.

    Full Text Available The behavior of the buff-breasted babbler (Pellorneum tickelli was recorded from April 2010 to May 2012 along creeks in Doi Chiang Dao Wildlife Research Station, Chiang Mai, Thailand. Fifteen nests of the buff-breasted babbler were found on four creeks: Maeka, Maemard, Ong and Sikrobkrua. The general behavior of birds included foraging, excretion, locomotion, preening and vigilance. The complete breeding cycle of the buff-breasted babbler in this study was almost 1 mth. Egg clutch size was in the range 3–4 and the nestlings hatched almost simultaneously. The eggs were incubated by both the males and the females. After hatching, both parents invested in intensive parental care. As well as providing food, they also protected their nestlings. This information can be used to help with conservation planning in the area and elsewhere. Keywords: Bird nest, Breeding birds, Nestling, Parental care, Riparian

    Full Text Available Objetivou-se analisar o crescimento inicial de dois clones do híbrido Eucalyptus × urograndis em diferentes sistemas de manejo da matocompetição, ao longo do tempo, no ano de implantação em áreas amapaenses. O trabalho foi desenvolvido na Amapá Florestal e Celulose S.A. (AMCEL, no período de setembro de 2006 a novembro de 2007, em duas áreas experimentais localizadas no município de Itaubal, AP (0°42'N; 50°48'W onde foram plantados de forma mecanizada dois diferentes clones do híbrido Eucalyptus × urograndis, caracterizando um clone por talhão (H3911 e H3243. A limpeza das áreas foi realizada por meio de aplicação do herbicida glifosato. O experimento foi alocado em delineamento de medidas repetidas, com os arranjos: Dois clones - H3911 e H3243; seis tratamentos - T1: sem limpeza; T2: limpeza total com herbicida; T3: limpeza com herbicida em duas faixas de 50cm na linha de plantio; T4: limpeza com herbicida em duas faixas de 75cm na linha de plantio; T5: limpeza com herbicida em duas faixas de 100 cm na linha de plantio e, T6: coroamento com 75 cm de raio por meio de herbicida; com quatro repetições. Foram mensuradas durante os primeiros quatro meses de avaliação apenas as alturas das plantas. A partir do quinto mês, além das alturas foram mensurados os diâmetros a 1,30 m do solo (DAP. Foi realizado o teste de esfericidade de Mauchly e testadas às hipóteses de nulidade das interações tempo x clone e tempo x clone x tipos de limpezas, e quando verificadas diferenças significativas (p < 0,05, as médias foram comparadas por meio do teste de Tukey. Em relação ao clone H3911, o tratamento com maior T5 e o de limpeza total, as alturas mostraram-se estatisticamente semelhantes, o que não ocorreu com os demais tipos de limpezas. Quanto aos DAP's das plantas do clone H3911, foi observado crescimento com repostas similares, no entanto com diferentes velocidades de crescimento durante o período de avaliação, com T1 e T

    Full Text Available Neoplasias provenientes do epitélio de revestimento do plexo coróide são inco-muns, tendo sido descritos 6 padrões morfológicos. O padrão anaplásico, também denominado carcinoma do plexo coróide, é o de menor freqüência e pode dar metastases fora do SNC. A distinção histológica desses tumores, particularmente da variedade anaplásica, com outras neoplasias primárias e metastáticas no SNC pode ser difícil. O uso de técnicas imunocitoquimicas em parafina tem-se mostrado útil no esclarecimento das linhagens tumorais. Os papilomas do plexo coróide têm, no entanto, sido objeto de controvérsia, por sua complexa expressão antigênica. Usando a técnica de imunoperoxidase (sistema avidina-biotina-peroxidase pesquisaram-se, em dois casos da variedade anaplásica, os seguintes marcadores: proteína glial fibrilar ácida (GFAP com anticorpo monoclonal e policlonal; ceratinas de 40-50kDa, ceratinas de 60-70kDa (callus ceratina, enolase neuronal específica (NSE e proteína S-100, com anticorpos monoclonais. Os dois tumores mostraram positividade para NSE, proteína S-100 e ceratina de 40-50kDa; uma das duas neoplasias mostrou diferenciação glial, revelando positividade para GFAP tanto com anticorpo monoclonal quanto policlonal.

Verificou-se crescimento micelial por meio de medidas do raio avaliadas pela Análise de Dados Longitudinais. Os dados obtidos foram submetidos à analise estatística (Manova. O crescimento foi significativamente diferente ao longo do tempo e este influenciou marcadamente o comportamento dos isolados nos diferentes resíduos. Observaram-se quatro padrões de comportamento para o isolado 42 e cinco, para o 47. As serragens de Eucalyptus sp. e de G. robusta mostraram-se as mais propícias ao crescimento dos dois isolados de L. edodes, confirmando ser essa espécie essencialmente de hábito lignícola.With the purpose of verifying the mycelial growth of two isolated strains of Lentinula edodes – 42 and 47 –, the following substrates were used: sawdusts of Eucalyptus sp., Grevillea robusta and Melia azedarach; cotton residue and leaves of Panicum maximum, in different compositions and complemented with crumbs of soy and rice. Mycelial growth was verified through radius measurements as evaluated by Longitudinal Data Analysis. The obtained data was submitted to statistical analysis (Manova. The growth was significantly different along time, and this influenced remarkably the behavior of the isolated strains in the different residues. Four patterns of behavior were observed for isolate 42, and five for number 47. The sawdusts of Eucalyptus sp. and of G. robusta proved to the most favorable for growing the two isolates of L. edodes, confirming this species to be essentially lignous.

    2015-04-01

    Full Text Available Most behavioral decision research takes place in carefully controlled laboratory settings, and examination of relationships between performance and specific real-world decision outcomes is rare. One prior study shows that people who perform better on hypothetical decision tasks, assessed using the Adult Decision-Making Competence (A-DMC measure, also tend to experience better real-world decision outcomes, as reported on the Decision Outcomes Inventory (DOI. The DOI score reflects avoidance of outcomes that could result from poor decisions, ranging from serious (e.g., bankruptcy to minor (e.g., blisters from sunburn. The present analyses go beyond the initial work, which focused on the overall DOI score, by analyzing the relationships between specific decision outcomes and A-DMC performance. Most outcomes are significantly more likely among people with lower A-DMC scores, even after taking into account two variables expected to produce worse real-world decision outcomes: younger age and lower socio-economic status. We discuss the usefulness of DOI as a measure of successful real-world decision making.

    Full Text Available O texto apresenta uma análise simbólica sobre a representação do gênero feminino dramatizada nos filmes Dona Flor e seus dois maridos (1976 e A festa de Babette (1987. Ambientados em contextos socio-históricos diferentes, tais filmes podem ser vistos como “etnografias” que falam do imaginário religioso e do ethos cultural protestante na Dinamarca de fins do século 19 e do sincretismo afro-brasileiro da primeira metade do século 20. O ponto de vista da antropologia simbólica, alimentada pelas contribuições teóricas de Clifford Geertz, Marcel Mauss, Victor Turner e Roberto DaMatta, orienta a interpretação dos filmes a partir dos códigos culturais da culinária (comida, da corporalidade (sexualidade e da religiosidade (puritanismo e sincretismo. Destaca-se, nessas “etnografias fílmicas”, o modo como os sistemas da dádiva e da carnavalização que as estruturam convergem para um mesmo campo de significação. A estratégia metodológica adotada consiste em comparar os filmes tendo por base a estrutura conceitual dos “dramas sociais”

    Full Text Available O presente trabalho apresenta um relato de experiência inclusiva: interação entre duas turmas de escolas: comum – Colégio Metodista Izabela Hendrix e especial – Instituto São Rafael. A importância de tal relato aponta no sentido de fomentar aos educadores o processo de transformação da educação, considerando a diversidade. Para a reflexão da experiência, utilizou-se a legislação vigente sobre a inclusão, conceituação de aprendizagem de Vygotsky e aprendizagem cooperativa do Ministério da Educação. A experiência ocorreu em dois momentos: preparação dos alunos da escola comum e o encontro das duas turmas. Os alunos tiveram informações a respeito da deficiência visual - como lidar com as crianças com deficiência visual, apresentação do Sistema de Leitura e Escrita Braille e de equipamentos pedagógicos. A vivência inclusiva fluiu de maneira muito espontânea e prazerosa, demonstrando a possibilidade de práticas inclusivas de forma constante na vida de cada indivíduo, considerando e respeitando as potencialidades das pessoas com ou sem deficiência.

    1998-10-01

    Full Text Available O tratamento cirúrgico dos aneurismas toracoabominais exige toracofreno laparotomia, períodos prolongados de pinçamento aórtico com isquemia visceral, sangramento abundante de difícil controle, complicações pulmonares, renais, neurológicas e distúrbios de coagulação com morbimortalidade muitas vezes proibitiva para pacientes de idade avançada, ou portadores de distúrbios respiratórios, renais ou cardíacos prévios. A rotura aumenta em muito a já elevada taxa de morbimortalidade. Crawford (1-3 e Borst (4 descreveram operação em dois tempos para tratamento de aneurisma que atinge mais de um segmento da aorta, com bons resultados. O objetivo de nosso trabalho é mostrar a técnica cirúrgica em dois tempos, empregando prótese intraluminal sem sutura (5, 6. Esta técnica nos proporciona uma operação menos agressiva por abordar somente o segmento roto da aorta, portanto apenas uma cavidade é manipulada (tórax ou abdome. A anastomose com prótese intraluminal reduz em muito o tempo de pinçamento da aorta e, conseqüentemente, a isquemia visceral, diminuindo, também, o sangramento. A redução da agressividade cirúrgica sobre estes pacientes já gravemente enfermos nos proporcionou bons resultados cirúrgicos.The surgical management of thoracoabdominal aneurysms requires thoracophrenic laparotomy, prolonged periods of aortic clamping with visceral ischemia, profuse bleeding leading to a difficult postoperative course with pulmonary, renal, neurological complications, coagulation disturbances and others. All this resulting in an elevated morbidity/mortality very often contraindicating it for the very elderly or those with prior respiratory, renal or cardiac symptoms. Rupture of this aneurysm greatly increases the already high rate of morbidity/mortality. Crawford and Borst have described a two-stage surgery with good results, for aneurysms that affect more than one segment of aorta. The objective of our report is to demonstrate

    Full Text Available In this article the author discusses the forty years of the PPGE/UFSCar distinguishing two periods in its history. The first one is the creation of the Master's degree (1976 and the consolidation of the Program when the PhD was founded (1990, time when there were few of them in Brazil. The second period was characterized by reforms and growth of the PPGE in the context of the expansion of Post-Graduation in Brazil. These periods are connected to the change in the evaluation pattern by CAPES, which directly influenced the life and configuration of the PPGE in what it is currently.

    Dopamine D2LR-serotonin 5-HT2AR heteromers were demonstrated in HEK293 cells after cotransfection of the two receptors and shown to have bidirectional receptor-receptor interactions. In the current study the existence of D2L-5-HT2A heteroreceptor complexes was demonstrated also in discrete regions of the ventral and dorsal striatum with in situ proximity ligation assays (PLA). The hallucinogenic 5-HT2AR agonists LSD and DOI but not the standard 5-HT2AR agonist TCB2 and 5-HT significantly increased the density of D2like antagonist (3)H-raclopride binding sites and significantly reduced the pKiH values of the high affinity D2R agonist binding sites in (3)H-raclopride/DA competition experiments. Similar results were obtained in HEK293 cells and in ventral striatum. The effects of the hallucinogenic 5-HT2AR agonists on D2R density and affinity were blocked by the 5-HT2A antagonist ketanserin. In a forskolin-induced CRE-luciferase reporter gene assay using cotransfected but not D2R singly transfected HEK293 cells DOI and LSD but not TCB2 significantly enhanced the D2LR agonist quinpirole induced inhibition of CRE-luciferase activity. Haloperidol blocked the effects of both quinpirole alone and the enhancing actions of DOI and LSD while ketanserin only blocked the enhancing actions of DOI and LSD. The mechanism for the allosteric enhancement of the D2R protomer recognition and signalling observed is likely mediated by a biased agonist action of the hallucinogenic 5-HT2AR agonists at the orthosteric site of the 5-HT2AR protomer. This mechanism may contribute to the psychotic actions of LSD and DOI and the D2-5-HT2A heteroreceptor complex may thus be a target for the psychotic actions of hallunicogenic 5-HT2A agonists.

    Full Text Available São descritos dois casos de quarto ventrículo isolado sendo o primeiro decorrente de hemorragia cerebelar e o segundo de hidrocefalia congênita com múltiplas revisões de válvula e cisto de Dandy-Walker. O tratamento cirúrgico é revisado na literatura. A abordagem direta à fossa posterior acha-se indicada nos casos de cisto no interior do quarto ventrículo. Naqueles sem a presença de cisto, deve-se empregar sistema de drenagem do quarto ventrículo, independente da drenagem supratentorial.Two cases of isolated fourth ventricle are reported, the first due to cerebellar haemorrhage, and the second due to congenital hydrocephalus with multiple shunt revisions and Dandy-Walker cyst. In our opinion, there are two basic treatment for isolated forth ventricle. The direct approach to the fourth ventricle is indicated when there is presence of an intraventricular cyst. The fourth ventricular shunting, independent of the supratentorial shunt, is the best treatments for patients with an isolated fourth ventricle without the presence of a cyst.

    Full Text Available Este artigo compara o Turismo Arqueológico, ou Arqueoturismo, em duas situações distintas no Brasil: um conjunto de sítios paleolíticos no Distrito Federal e um sítio colonial, onde o turismo tem sido explorado na Amazônia Brasileira, no Pará. Em Brasília, fruto de uma pesquisa de doutorado, o turismo foi analisado como uma opção de uso e de gestão do patrimônio com baixíssima visibilidade e consequente baixo potencial turístico. E na Amazônia, fruto de uma pesquisa em andamento de pós-doutoramento, o turismo tem sido avaliado enquanto ferramenta de preservação e de inclusão do público. Nas duas pesquisas, constata-se uma grande expectativa dos públicos em relação ao aproveitamento turístico, e o baixo aproveitamento da atividade nos sítios analisados até o momento. Nos dois estudos, notam-se benefícios de natureza coletiva, elencados como capitais simbólicos.

    Full Text Available Este artigo tem como objetivo analisar de que maneira se dá a construção de personagens queer na literatura quando suas identidades são constituídas de maneira interseccional à identidade latina nos Estados Unidos. Para isso, foram selecionados dois contos da coletânea From macho to mariposa: new gay latino fiction (2011, organizada por Charles Rice-González e Charlie Vázquez. Verificou-se, assim, de que maneira a interseccionalidade étnica que compõe a identidade desses sujeitos, a saber, a ascendência latino-americana, afeta suas vivências enquanto sujeitos queer, além de discutir o modo pelo qual esses sujeitos, já segregados devido a questões étnicas e culturais, sofrem um novo processo de marginalização em função de sua expressão de gênero e/ou sexualidade.

    NOAAs Regional Integrated Sciences and Assessments (RISA) Teams, DOIs Climate Science Centers (CSCs), and USDAs Regional Climate Hubs (RCHs) have common missions of integrating climate and related knowledge across scientific disciplines and regions to create "actionable" information that decision-makes can use to manage climate risks and impacts at state and local scales. However, the sponsoring agency programs, university investigators, and local federal officials govern each differently. The three models of program and center governance are 1) exclusively university (RISAs), 2) a hybrid of Federal government and (host) university (CSCs,), and 3) exclusively Federal (Hubs). Each model has it's advantages and disadvantages in terms of legal definition and authority, scientific mission requirements and strategies, flexibility and legitimacy to conduct research and to collaborate regionally with constituencies, leadership and governance approach and "friction points,", staff capacity and ability to engage stakeholders, necessity to deliver products and services, bureaucratic oversight, performance evaluation, and political support at Congressional, state, and local levels. Using available sources of information and data, this paper will compare and contrast the strengths and weakness of these three regional applied climate science center governance models.

    Full Text Available O presente trabalho analisa a estrutura narrativa do romance O tambor (Die Blechtrommel de Günter Grass e do filme homônimo dirigido por Volker Schlöndorff, observando a forma como o romancista articula a construção complexa de seu foco narrativo e como o cineasta trabalha essa estrutura em seu filme, o que resulta em diferentes formas de perceber e interpretar tanto o narrador-personagem quanto o universo no qual está inserido, levando em consideração que a discussão sobre adaptações de obras literárias em realizações cinematográficas já passou da discussão moralizante da fidelidade ou traição para uma discussão menos valorativa. O artigo enfatiza o estudo da intertextualidade entre a adaptação cinematográfica e o romance original, tendo como pontos de observação o tipo de seleção feita no processo da realização fílmica, a concretização visual do texto literário, a atualização de determinados temas abordados na obra e o foco narrativo, por exemplo.

    Full Text Available O texto representa uma tentativa de tratar a experiência universitária situando-a entre dois liberalismos, o dos fundadores da USP, a que chamamos liberalismo ilustrado, e o neoliberalismo atual. Neste sentido, organiza elementos e esboça uma reflexão comparativa, de ordem histórica e institucional, sobre a universidade brasileira, muito especificamente a USP, focalizando o período compreendido entre os anos 30 e a atualidade. Com isso se pretende compreender a transformação de um projeto inicial e fundador num projeto terminal, aquele que está sendo implementado em nome de uma racionalização modernizadora. O objetivo do texto é, portanto, o entendimento do presente e dos compromissos que são solicitados a assumir aqueles que de alguma maneira vincularam suas vidas ao destino da Instituição.This text represents an atempt to deal with the university experience placing it between the two liberalisms; one from the founders of USP, which is called lllustrated Liberalism, and the other one, that is the recent neo-liberalism. In this way, this text organizes topics and outlines a comparative reflection concerning the history and Institution of the Brazilian university, and more often of USP, highlighting the period between 1930 's and nowadays. This text tries to understand the transformation of an inicial project and its final project, which is being implemented nowadays due to a modern rationalization. In other words, the objective of this text is to understand the present situation of the university, and the compromises of whom, in some way, attached their lives to the destiny of the Institution.

    Full Text Available A acerola é um fruto de grande potencial econômico e nutricional devido ao seu alto teor de vitamina C, destacando-se como alimento funcional. É comercializada principalmente na forma de polpa congelada e fruto in natura. O objetivo deste estudo foi avaliar a qualidade dos frutos da aceroleira cv. Olivier em dois estádios de maturação. Para tanto, foram colhidas amostras de frutos em um pomar comercial no município de Junqueirópolis-SP. Foram realizadas a determinação da cor externa dos frutos e análises das características químicas de teor de sólidos solúveis, pH, acidez titulável, açúcares redutores, 'ratio' e ácido ascórbico de frutos semi-maduros e maduros. Os resultados obtidos permitiram concluir que os frutos semimaduros apresentaram maior acidez total, menor teor de sólidos solúveis e menor concentração de açúcares; no entanto, estes frutos apresentaram maiores teores de vitamina C, expressa em ácido ascórbico. Portanto, quando se buscam altos índices de vitamina C, os frutos devem ser colhidos num estádio de maturação menos avançado, com coloração alaranjada. O estudo demonstrou também que a cv Olivier produz frutos com características adequadas tanto para o mercado in natura quanto para a indústria, apresentando boa coloração e características químicas dentro dos padrões para esta fruta.

    1955-12-01

    Full Text Available São apresentados dois casos de angiografia vértebro-basilar em pacientes submetidos a angiografia cerebral via carótida. Na discussão do mecanismo dessa eventualidade angiográfica é admitido o refluxo da substância radiopaca até a artéria subclávia de onde o contraste seria levado, pela corrente sangüínea, para o interior da artéria vertebral. Para que o contraste pudesse progredir em sentido contrário ao normal, é forçoso admitir a existência de uma oclusão da carótida acima do ponto em que ela fôra puncionada. Quanto à causa determinante do bloqueio vascular julgamos provável que se trate de uma válvula artificial resultante da laceração da íntima, como no caso de Sirois e col. Tendo a atenção despertada pelos casos relatados neste trabalho, pudemos obter, deliberadamente, angiografia do sistema vértebro-basilar injetando o contraste na carótida primitiva (punção percutânea e ocluindo êste vaso, mediante compressão digital acima do nível da punção. Para maior aproveitamento do contraste, um manguito insuflado, até o desaparecimento do pulso radial, é colocado no braço. Com êste artifício visamos impedir que parte do contraste seja levado, inutilmente, para os vasos do membro superior. Os pormenores do método e os resultados serão descritos em trabalho que será publicado oportunamente.

    We are developing a PET system integrated with a birdcage RF-coil for PET-MRI in order to realize both high sensitivity and high spatial resolution of the PET image by using the 4-layered depth-of-interaction (DOI) PET detector. We constructed a full-ring prototype system and evaluated performances, especially imaging performance, of the prototype system in simultaneous measurement. The prototype system consists of eight four-layer DOI-PET detectors and a prototype birdcage RF-coil developed for the proposed system. The PET detectors consist of six monolithic multi-pixel photon counter array (S11064-050P), a readout circuit, fourlayer DOI scintillator arrays and a shielding box made of 35 μm thick copper foil. The crystal array consists of 2.0 mm x 2.0 mm x 5.0 mm LYSO crystals arranged in 38 x 6 x 4 layer. The RF-coil has eight coil elements and the eight PET detectors are positioned at each element gap. The diameter of the RF-coil elements is 261 mm. We conducted performance tests of the prototype system with a 3.0 T MRI (MAGNETOM Verio). Only the PET detectors, the RF-coil and the cables were in an MRI room during measurements. A data acquisition system and power supplies for the MPPCs and preamplifiers were outside the MRI room and connected to all the detectors through a penetration panel. As a result, the spatial resolutions of a Na-22 point source in the PET image were lower than 1.6 mm in whole the FOV due to the DOI capability. In addition, the influence of the simultaneous measurements on the PET performance is negligible. On the other hand, the SNR of the phantom image in the magnitude images was degraded from 259.7 to 209.4 due to noise contamination from the power supplies.

    We have been developing a submillimeter resolution and low-cost DOI-PET detector using wavelength shifting fibers (WLSF), scintillating crystal plates and MPPCs (Hamamatsu Photonics). Conventional design of DOI-PET detectors had approximately mm 3 of resolution by using some scintillating blocks with a volume of 1 mm 3 , which detects gamma-ray. They are expensive due to difficulties in processing scintillating crystals and a large number of photo-detectors, and these technologies are likely to reach the limit of the resolution. Development of a lower cost DOI-PET detector with higher resolution is challenging to popularize the PET diagnosis. We propose two type of PET detector. One is a whole body PET system, and the other is a PET system for brain or small animals. Each PET system consists 6 blocks. The former consists of 6 layers of crystal plates with 300 mm x 300 mm x 4 mm. The latter consists of 16 crystal layers, forming 4 x 4 crystal arrays. The size of the crystal plate is 40 mm x 40 mm x 1 mm. Wavelength shifting fiber (WLSF) sheets are attached to above and up and down side of crystal planes. The whole PET system has 8 MPPCs attached on each side. For the brain PET detector, 9 WLSF fibers are attached on the each side. The expected position resolution would be less than 1 mm at the former system. We have performed an experimental performance estimation for the system component using 22 Na radioactive source. We achieved a collection efficiency of 10% using the WLSF sheet and Ce:Gd 3 (Al,Ga) 5 O 12 (GAGG) crystals at 511 keV. The linear relationship between reconstruction position and incident position was obtained, and a resolution of 0.7 mm (FWHM) for x-axis of DOI by the WLSF readout was achieved. (authors)

    GBIF—the Global Biodiversity Information Facility—has recently demonstrated a system that tracks publications back to individual datasets, giving data providers demonstrable evidence of the benefit and utility of sharing data to support an array of scholarly topics and practical applications. GBIF is an open-data network and research infrastructure funded by the world's governments. Its community consists of more than 90 formal participants and almost 1,000 data-publishing institutions, which currently make tens of thousands of datasets containing nearly 800 million species occurrence records freely and publicly available for discovery, use and reuse across a wide range of biodiversity-related research and policy investigations. Starting in 2015 with the help of DataONE, GBIF introduced DOIs as persistent identifiers for the datasets shared through its network. This enhancement soon extended to the assignment of DOIs to user downloads from GBIF.org, which typically filter the available records with a variety of taxonomic, geographic, temporal and other search terms. Despite the lack of widely accepted standards for citing data among researchers and publications, this technical infrastructure is beginning to take hold and support open, transparent, persistent and repeatable use and reuse of species occurrence data. These `download DOIs' provide canonical references for the search results researchers process and use in peer-reviewed articles—a practice GBIF encourages by confirming new DOIs with each download and offering guidelines on citation. GBIF has recently started linking these citation results back to dataset and publisher pages, offering more consistent, traceable evidence of the value of sharing data to support others' research.

    We are developing a PET system integrated with a birdcage RF-coil for PET-MRI in order to realize both high sensitivity and high spatial resolution of the PET image by using the 4-layered depth-of-interaction (DOI) PET detector. We constructed a full-ring prototype system and evaluated performances, especially imaging performance, of the prototype system in simultaneous measurement. The prototype system consists of eight four-layer DOI-PET detectors and a prototype birdcage RF-coil developed for the proposed system. The PET detectors consist of six monolithic multi-pixel photon counter array (S11064-050P), a readout circuit, fourlayer DOI scintillator arrays and a shielding box made of 35 μm thick copper foil. The crystal array consists of 2.0 mm x 2.0 mm x 5.0 mm LYSO crystals arranged in 38 x 6 x 4 layer. The RF-coil has eight coil elements and the eight PET detectors are positioned at each element gap. The diameter of the RF-coil elements is 261 mm. We conducted performance tests of the prototype system with a 3.0 T MRI (MAGNETOM Verio). Only the PET detectors, the RF-coil and the cables were in an MRI room during measurements. A data acquisition system and power supplies for the MPPCs and preamplifiers were outside the MRI room and connected to all the detectors through a penetration panel. As a result, the spatial resolutions of a Na-22 point source in the PET image were lower than 1.6 mm in whole the FOV due to the DOI capability. In addition, the influence of the simultaneous measurements on the PET performance is negligible. On the other hand, the SNR of the phantom image in the magnitude images was degraded from 259.7 to 209.4 due to noise contamination from the power supplies.

    Conventionally, positron emission tomograph (PET) scanners use scintillators which have a high effective atomic number. Recently, novel scintillators like LaBr{sub 3} have been developed which have excellent timing and energy resolutions. LaBr{sub 3} has a high performance for PET scanner use, but its effective atomic number is lower than that of lutetium oxyorthosilicate (LSO). As an alternative, we have developed a scatter reduction method using depth-of-interaction (DOI) information and energy information to increase the sensitivity. The sensitivity of the PET scanner with LaBr{sub 3} can be improved using the DOI-dependent extended-energy window (DEEW) method. In this work, our method is applied to the whole-body LSO/LaBr{sub 3} PET scanner using the GATE simulation toolkit. Simulation results show the number of true coincidences can be increased while minimizing the scatter and random coincidences by using the DEEW method. Noise equivalent count rate (NECR) can be improved by 20-70% for the whole-body DOI-PET scanner. Sensitivity of the PET scanner with a scintillator of low-effective atomic number can be improved by the DEEW method.

    Full Text Available Onychomycoses constitute pathologies frequently seen in dermatological practice worldwide. Usually, they are caused by two groups of pathogenic fungi: dermatophytes and yeasts of the Candida genus. However, in a small fraction of the cases, the etiologic agents comprise nondermatophyte molds, belonging to several genera and species. The objective of this study was to present two cases of onychomycosis associated to the mold Scytalidium dimidiatum in patients residing in two cities of Santa Catarina State, Brazil. Aspects of fungal pathogenesis, as well as the epidemiological characteristics and laboratory diagnosis, are discussed.Onicomicoses se apresentam como infecções fúngicas localizadas, muito freqüentes na prática dermatológica. Na grande maioria das vezes, são causadas por dois grupos: dermatófitos e leveduras do gênero Candida. Entretanto, em um pequeno percentual dos casos, os agentes etiológicos compreendem fungos filamentosos não-dermatófitos, pertencentes a vários gêneros e espécies. O objetivo deste trabalho foi o de apresentar dois casos de onicomicose associados à espécie Scytalidium dimidiatum em pacientes residentes em dois municípios do estado de Santa Catarina, Brasil.

    Full Text Available OBJETIVO: Comparar o consumo alimentar de dois grupos de mulheres portadoras de câncer de mama atendidas em dois períodos distintos: 1999-2004 e 2005-2009. MÉTODOS: Estudo documental, com abordagem descritiva e comparativa. Foram coletados dados de identificação e de ingestão alimentar nas fichas de 154 pacientes portadoras de câncer de mama atendidas em serviços de referência de Fortaleza (CE: 66 no período de 1999-2004 e 88 no de 2005-2009. Foram considerados como integrantes do hábito os alimentos consumidos pelo menos quinzenalmente por, no mínimo, 50% das pessoas. Calculou-se a prevalência de consumo de alimentos, sendo os padrões dos dois períodos comparados pela aplicação dos testes Quiquadrado ou exato de Fisher, e adotouse p<0,05 como nível de significância. RESULTADOS: Os hábitos alimentares dos dois grupos foram semelhantes, exceto quanto ao maior consumo de leite e de cenoura e menor consumo de manga e caju, além de uma tendência ao aumento no consumo de óleo de soja, observada no grupo atendido mais recentemente. O aumento de leite e de cenoura pode configurar proteção contra a recidiva da doença, mas a redução do consumo das frutas citadas pode significar maior risco: aliás, foram baixas as prevalências de consumo de frutas e hortaliças pelos dois grupos de mulheres. CONCLUSÃO: Os achados apontam para uma lacuna na abordagem educativa das pacientes tanto no passado como na atualidade, o que comprova a necessidade de incentivar maior consumo e variedade de hortaliças e frutas e menor consumo de cereais refinados, gorduras, açúcar e refrigerantes.

    Full Text Available A Hemoglobina Paroxística Noturna (HPN é uma doença adquirida da stem cell hematopoética caracterizada por anemia hemolítica crônica, episódios trombóticos, e com freqüência pancitopenia. É uma desordem clonal, causada por mutação somática do gene PIG-A ligado ao cromossomo X, o qual é requisitado para a formação da estrutura da âncora glicosil-fosfatidil-inositol (GPI. A deficiência da GPI ancorada á proteína CD59 explica a hemólise intravascular na PNH, resultando da inabilidade dos eritrócitos inativar a superfície do complemento. Uma imensa relação clínica existe entre HPN e a anemia aplástica (AA. A ausência de GPI ancorada às proteínas é facilmente detectada pelos métodos de citometria de fluxo aplicados aos eritrócitos e leucócitos; os testes de Ham a da sucrose são absolutos. Em algumas vezes o tratamento com corticóides e/ou androgênio é útil. O transplante de medula óssea alogênico é curativo. O objetivo deste artigo é relatar dois casos de HPN com revisão, enfatizando os aspectos fisiopatológicos, clínicos, diagnósticos e tratamento da HPN.Paroxysmal nocturnal hemoglobinuria (PNH is an acquired hematopoietic stem cell disease characterized by chronic hemolytic anemia, thrombotic episodes and often pancytopenia. It is a chronic disorder caused by a somatic mutation of the X-linked gene PIG-A, which is required for formation of the glycosylphosphatidylinositols (GPI - anchor structure. Deficiency of the GPI-anchored protein CD59 explains intravascular hemolysis in PNH, which results from the inability of erythrocytes to inactivate the surface complement. A very strong clinical relationship exists between aplastic anemia (AA and PNH. Absence of GPI-anchored proteins is easily detected by flow cytometric methods applied to both erythrocytes and leukocytes; the Ham and sucrose tests are now obsolete. Treatment with glucocorticoids and / or androgen is sometimes helpful. Allogeneic

Seis grupos de seis ratos machos Wistar recém-desmamados foram alimentados durante catorze dias com as seguintes dietas: controle (C10 - caseína, formulado protéico (FP10 e gelatina (G10 ao nível de 10 % de proteína; misturas de caseíma com formulado protéico (C7 FP3 ou gelatina (C7G3 (7:3 em base protéica, respectivamente; e dieta aprotéica. As dietas contendo o formulado protéico apresentaram boa qualidade protéica, segundo os índices NPR (Net Protein Ratio e NPU (Net Protein Utilization, sem diferenças significativas entre C7 FP3 e C10 (NPR= 4,00 e 4,11, e NPU= 65% e 67%, respectivamente. Os animais alimentados com gelatina (G10 e com dieta aprotéica perderam peso corpóreo e apresentaram pesos semelhantes dos fígados e inferiores aos dos demais grupos de ratos. O valor protéico da mistura caseína-gelatina (C7G3 foi menor que o da caseína (NPR relativo= 77 %, p<0,05. O formulado protéico constitui uma fonte de proteína de boa qualidade e seu uso como suplemento alimentar pode ser indicado em situações especiais. A gelatina, por sua vez, não pode ser considerada um complemento ou suplemento nutricional, pois não atende às necessidades protéicas do organismo e pode prejudicar a disponibilidade biológica de proteínas de boa qualidade.

    Full Text Available A displasia fibrosa do osso temporal é uma doença de etiologia ainda controversa, manifestando-se principalmente por estenose progressiva do conduto auditivo externo e pela perda condutiva da audição. Outras manifestações incluem abaulamento na região temporal ou retroauricular, otorréia, otalgia e disacusia sensório-neural. A incidência é maior no sexo masculino e acomete principalmente a raça branca. O exame radiológico característico demonstra um aspecto de "vidro-fosco" homogêneo envolvido por uma concha de tecido cortical denso, embora existam outros padrões radiológicos desta enfermidade. O exame microscópico demonstra um trabeculado ósseo semelhante aos caracteres chineses. Este estudo relata dois casos de displasia fibrosa do osso temporal que se destacam, pois ultrapassaram o osso temporal, acometendo a região zigomática, sendo que no segundo caso houve também comprometimento do osso esfenóide e o pterigóide. Os pacientes foram submetidos à mastoidectomia radical modificada e tiveram boa evolução.Fibrous dysplasia of the temporal bone (FDTB is a disorder which etiology is still controversial. Its main clinical feature is a progressive narrowing of the external auditory canal following by conductive hearing loss. Temporal or retroauricular enlargement, ear discharge, otalgia, and sensorineural hearing loss are additional findings. Women and Caucasians are more affected. The prominent finding is a homogeneous radiodense "grounded glass" like image shell surrounded by dense cortical tissue. However, other radiological patterns of this disease may be displayed. Microscopically, a trabecular of bone in "Chinese letter" configuration is found. The two cases of FDTB herein reported are particularly special for a far beyond temporal commitment reaching the zygomatic area in the first case and sphenoid and pterygoid bones in the second one.

    Full Text Available As Unidades de Conservação vem se estabelecendo como uma estratégia imprescindível para a conservação de fragmentos de florestas e da biodiversidade. Devido a sua importância, ferramentas e pesquisas estão sendo cada vez mais desenvolvidas para permitir a atualização da paisagem e para o diagnóstico da situação dessas Unidades de Conservação. Aliado a isso, as geotecnologias estão sendo usadas como alternativas nos estudos ambientais, fornecendo meios para uma análise mais precisa e mais próxima do real. Nessa perspectiva, o objetivo do trabalho foi identificar e analisar as características físicas, topográficas e temáticas do Parque Estadual Dois Irmãos, localizado em Recife – PE, a partir da utilização de técnicas do geoprocessamento, aplicando recursos do software do Sistema de Processamento de Informações Georreferenciadas, o SPRING e o QUANTUM GIS e a utilização de imagens SRTM. Para isso foi realizado trabalho de campo para a captação das coordenadas geográficas de alguns itens do Parque, para a montagem do banco de dados e criação do mapa de estruturas físicas. Também foi utilizado as imagens SRTM para a construção do mapa da declividade e do mapa hipsométrico. Após a criação dos mapas identificou-se os tipos de relevo predominantes do Parque. Em relação à declividade 87% do relevo do Parque foi classificado entre Moderadamente Ondulado a Forte Ondulado e a sua altimetria variou de 0 a 105 metros. Diante dos resultados observados, o uso dos SIG’s e de dados SRTM, revelou-se como uma importante ferramenta empregada na identificação e espacialização prévia das unidades de relevo.

    2017-04-01

    For finding, linking and citing research content, persistent digital identifiers are the key, as a persistent identifier is a long-lasting reference to a resource. But are PIDs really used as they should be? With respect to the obstacles of the PID systems, we face a diverse landscape of stakeholders, legacy systems, competing interests and often incomprehensible messaging filled with technical jargon around PIDs. Insufficient metadata quality is another major challenge for these systems. While the principal task for service providers lies in collaborating to provide a shared and easy to use PID infrastructure, it is the key responsibility for data centers to provide rich metadata and structured access to research content. Especially metadata and structured access are imperative for the most basic services such as search, citation tracking and reuse. And of course all needs to be human- and machine interoperable, as we want our machines to be able to interpret PIDs depended on a specific use case. Since 2004, the German National Library of Science and Technology (TIB) has been providing DOI services to data centers in Germany. Recent developments make clear that requirements for PIDs have changed. Science has developed a need for PIDs at multiple content levels: In addition to DOIs for journal articles and research data, PIDs for people, physical objects, collections, software, funders, organizations, expeditions, resources, instruments and even for data management plans are required to enable different platforms to exchange information consistently and unambiguously. In this work we want to emphasize on the distinct increases of total DOI registrations for research data and other research output such as images, videos or software in Germany within the past decade and how research institutes and universities differ in their DOI registration workflows. We present use cases which illustrate the deployment of DOIs e.g. for dynamic data, and demonstrate the need of

Descemet's membrane (DM, denuded by stromal necrosis, served as the starting point for dissection plane and creation of the recipient bed for DALK. The next steps were excision of the diseased stroma along the edge of trephination, and transplantation of a 400-450 µm thick, manually dissected lamellar graft. The remaining posterior layers of the donor cornea, 100-150 µm thick, were used as a graft in the DSEK procedure for PBK. The integrity of the globe was saved, and best-corrected visual acuity (BCVA of 20/40 was reached after DALK in the eye with an imminent corneal perforation. A subnormal central corneal thickness (CCT of 430 µm did not interfere with corneal shape (43.50 x 45.50 D and function. The graft remained attached and clear after DSEK in the eye with PBK, with BCVA of 20/30 and a CCT of 653 µm. One donor cornea can be used for two lamellar keratoplasties, DALK and DSEK. Although the described obstacles may prevent this approach from becoming widely used, it may prove useful when one is confronted with a need for an urgent anterior lamellar keratoplasty, a long list of cases for DSEK, and a shortage of donor corneas.Relato de caso descrevendo o uso de uma córnea doadora para dois procedimentos de transplante: ceratoplastia anterior lamelar profunda (DALK no caso de uma perfuração corneal iminente causada por necrose estromal por herpes vírus, e ceratoplastia com transplante de endotélio (DSEK no olho com ceratopatia bolhosa em pseudofacia (PBK.

    Full Text Available Com vistas ao aumento da produção agrícola, optou-se no Brasil, pelo acréscimo de área cultivada; para tal o uso indiscriminado da motomecanização mostrou-se eficiente em um primeiro momento, porém acarretando problemas à física do solo no decorrer dos anos. Paralelamente, práticas conservacionistas se fazem presentes, vide semeadura sob a palha (Plantio Direto, uma realidade no sul do Brasil. Sendo assim, avaliou-se a suscetibilidade de compactação de dois tipos de solo, ambos com sistema de semeadura sob a palha. Para dimensionar a suscetibilidade a compactação, utilizou-se ensaio de Proctor. Os solos foram ensaiados com e sem a presença de matéria orgânica livre. Os resultados demonstraram que para o Cambissolo, textura média, não houve diferença nos valores que representam a suscetibilidade, enquanto no Latossolo Vermelho, textura argilosa, não houve diferença entre a máxima densidade aparente, porém houve diferença significativa no conteúdo de água para a máxima densidade, o mesmo alterou-se de 0,249 g g-1 no ponto de máxima compactação no ensaio sem a presença de matéria orgânica livre, para 0,283 g g-1 no ponto de máxima compactação, quando da presença da matéria orgânica livre.For increasing agricultural production, Brazil opted to enlarge the cultivated area, and indiscriminate mechanization was efficient at the first moment, although it altered adversely the soil properties with the passage of time. At the same time, conservation practices, like the direct sowing under the straw (No Tillage were adopted which is a reality in Southern Brazil. Considering this, the susceptibility for compaction of two classes of soil was evaluated under no tillage system, with and without free organic matter. The Proctor test was used to measure the degree of compaction. The results of a medium texture Cambissol showed there was no difference in susceptibility for compaction. The clay textured Red Latossol, showed

    Full Text Available Boron deficiency causes large productivity losses in eucalypt stands in extensive areas of the Brazilian Cerrado region, thus understanding B mobility is a key step in selecting genetic materials that will better withstand B limitation. Thus, in this study B mobility was evaluated in two eucalypt clones (68 and 129, under B sufficiency or B deficiency, after foliar application of the 10B isotope tracer to a single mature leaf. Samples of young tissue, mature leaves and roots were collected 0, 1, 5, 12 and 17 days after 10B application. The 10B:11B isotope ratio was determined by HR-ICP-MS. Samples of leaves and xylem sap were collected for the determination of soluble sugars and polyalcohols by ion chromatography. Boron was translocated within eucalypt. Translocation of foliar-applied 10B to the young tissues, mature leaves and roots was higher in clone 129 than in 68. Seventeen days after 10B application to a single mature leaf, between 14 and 18 % of B in the young tissue was originated from foliar B application. In plants with adequate B supply the element was not translocated out of the labeled leaf.A deficiência de boro tem causado perdas expressivas de produtividade em extensas áreas de eucalipto no Brasil, principalmente na região do Cerrado. A mobilidade de B é um fator chave na seleção de materiais genéticos mais tolerantes à deficiência deste nutriente. Neste trabalho, a mobilidade de B foi avaliada em dois clones de eucalipto (68 e 129, com e sem deficiência de B, após a aplicação foliar do traçador isotópico 10B em uma única folha madura. Amostras de tecidos jovens, folhas maduras e raízes foram coletadas nos tempos de 0, 1, 5, 12 e 17 dias após a aplicação. A determinação da razão isotópica 10B:11B foi feita por meio de HR-ICP-MS. Foram coletadas amostras de folhas e do exsudato xilemático para determinação de açúcares solúveis e poliálcoois, por meio de cromatografia iônica. Houve translocação de B

    X'tal cube is the cubic depth of interaction (DOI) PET detector which our research group developed. In this work, aiming to get higher sensitivity, we developed the long rectangular shape X'tal cube (long-XC) by extending the cubic X'tal cube structure in one direction. We verified performance of this long-XC and also studied detector parameters for optimization. The same as the X'tal cube, the crystal block of the long-XC is composed of a 3D array of cubic scintillation crystal elements. Reflectors are not inserted between these crystal elements. The scintillation light then spreads without being obstructed by reflectors and is detected by multiple numbers of the multi-pixel photon counters (MPPCs) coupled on all six sides of the crystal block. For crystal element identification, a simple Anger-type calculation is used. In this study, we arranged 3.0 mm×3.0 mm×3.0 mm LGSO crystal elements in a 6 × 6 × 14 array for the long-XC. In a previous study, we had already confirmed that for the X'tal cube consisting of a 6 × 6 × 6 array of the same crystal elements and 54 MPPCs, identification of all 216 crystal elements was possible and the average energy resolution for all the elements was about 11 %. The long-XC contains more than twice the number of the crystal elements but less than twice the number of the MPPCs compared to the previous X'tal cube. The detector parameters investigated with the long-XC were: the number of MPPCs on both sides in the extended direction (edge MPPCs); the MPPC type, the MPPCs of 25 μm × 25 μm or 50 μm × 50 μm pixel sizes; the material between the crystal elements, an air gap or an optical glue having a closer refractive index to that of LGSO than air has; and the MPPC signals used in the Anger-type calculation. Results of the crystal element identification performance showed that reducing the number of the edge MPPCs caused performance degradation only at the part near the edge. For the MPPC type, the 50 μm type was better than

    We are developing a PET-MRI system which consists of PET detectors integrated with the head coil of the MRI in order to realize high spatial resolution and high sensitivity in simultaneous measurements. In the PET-MRI system, the PET detectors which consist of a scintillator block, photo-detectors and front-end circuits with four-layer depth-of-interaction (DOI) encoding capability are placed close to the measured object. Therefore, the proposed system can achieve high sensitivity without degradation of spatial resolution at the edge of the field-of-view due to parallax error thanks to the four-layer DOI capability. In this paper, we fabricated a prototype system which consists of a prototype four-layer DOI-PET detector, a dummy PET detector and a prototype birdcage type head coil. Then we used the prototype system to evaluate the performance of the four-layer DOI-PET detector and the reciprocal influence between the PET detectors and MRI images. The prototype DOI-PET detector consists of six monolithic multi-pixel photon counter (MPPC) arrays (S11064-050P), a readout circuit board, two scintillator blocks and a copper shielding box. Each scintillator block consists of four layers of Lu 1.8 Gd 0.2 SiO 5 :Ce (LGSO) scintillators and reflectors are inserted between the scintillation crystals. The dummy detector has all these components except the two scintillator blocks. The head coil is dedicated to a 3.0 T MRI (MAGNETOM Verio, Siemens) and the two detectors are mounted in gaps between head coil elements. Energy resolution and crystal identification performance of the prototype four-layer DOI-PET detector were evaluated with and without MRI measurements by the gradient echo and spin echo methods. We identified crystal elements in all four layers from a 2D flood histogram and energy resolution of 15–18% was obtained for single crystal elements in simultaneous measurements. The difference between the average energy resolutions and photo-peak positions with and

    Full Text Available A adição de subprodutos orgânicos ao solo pode ocasionar mudanças na dinâmica da matéria orgânica dele, influenciando a atividade e utilização do carbono pelos microrganismos presentes nele. O objetivo deste trabalho foi avaliar a influência da aplicação de doses crescentes de subproduto da agroindústria de café nos atributos biológicos de dois solos com textura distinta, em diferentes tempos de incubação. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2 × 8, sendo dois solos e oito doses de subproduto de café, com cinco repetições. Foram realizadas coletas de subamostras dos solos aos 30, 60, 90 e 125 dias após a incorporação do subproduto nesses. Nessas datas foram avaliados o carbono microbiano (C-CBM, a respiração basal microbiana (RBM e o carbono orgânico total (COT. A adição do subproduto do café proporcionou aumentos nos valores de C-CBM, C-CO2 e COT dos dois solos utilizados. A maior atividade microbiana ocorreu no período de 30 dias, com maior liberação de C-CO2; o COT foi superior no solo argiloso por ele permitir maior proteção dos compostos orgânicos à decomposição pelos microrganismos.

    The Dutch Obesity Intervention in Teenagers (DOiT) programme is an evidence-based obesity prevention programme tailored to adolescents attending the first two years of prevocational education in the Netherlands. The initial programme showed promising results during an effectiveness trial. The programme was adapted and prepared for nationwide dissemination. To gain more insight into the process of translating evidence-based approaches into 'real world' (i.e., 'natural') conditions, our research aims were to evaluate the impact of the DOiT-implementation programme on adolescents' adiposity and energy balance-related behaviours during natural dissemination and to explore the mediating and moderating factors underlying the DOiT intervention effects. We conducted a cluster-controlled implementation trial with 20 voluntary intervention schools (n=1002 adolescents) and 9 comparable control schools (n = 484 adolescents). We measured adolescents' body height and weight, skinfold thicknesses, and waist circumference. We assessed adolescents' dietary and physical activity behaviours by means of self-report. Data were collected at baseline and at 20-months follow-up. We used multivariable multilevel linear or logistic regression analyses to evaluate the intervention effects and to test the hypothesised behavioural mediating factors. We checked for potential effect modification by gender, ethnicity and education level. We found no significant intervention effects on any of the adiposity measures or behavioural outcomes. Furthermore, we found no mediating effects by any of the hypothesised behavioural mediators. Stratified analyses for gender showed that the intervention was effective in reducing sugar-containing beverage consumption in girls (B = -188.2 ml/day; 95% CI = -344.0; -32.3). In boys, we found a significant positive intervention effect on breakfast frequency (B = 0.29 days/week; 95% CI = 0.01; 0.58). Stratified analyses for education level showed

    Full Text Available Among the many problems arising from poor sanitation that can affect wild birds maintained in captivity, parasitic afflictions are among the most frequent, and their effects can range from subclinical infections to death. Some of the most common cases involve endoparasites, principally if the species under consideration exists at a high population density. This being so, the aim of the current work was to report on the prevalence of endoparasites in faecal samples from cracids (curassows and allies bred in captivity at the Parque Dois Irmãos, Recife, Pernambuco state in Brazil. To do this, faecal and sand samples were collected from the enclosures of birds of the family Cracidae belonging to the collection from the Parque Dois Irmãos, which originated from private collections from the Metropolitan Region and Forest Zone of the State of Pernambuco. Four lots of faecal and sand samples were collected over a 60-day period, giving a total of 84 faecal samples from 58 individuals of 21 species of cracids. The material collected was submitted for coproparasitological tests using the right method and spontaneous sedimentation. The results obtained were positive for Strongyloides sp., Ascaridia sp., Capillaria sp. and cysts of Entamoeba coli, as well as eggs belonging to the superfamily Strongyloidea.

Foi utilizado o delineamento inteiramente casualizado, com dez repetições (amostragens, em esquema fatorial 2x3; utilizaram-se dois métodos de amostragem (pano-de-batida e pano-vertical e três espaçamentos entre linhas. A população de lagarta-da-soja e de percevejo-verde-pequeno foi avaliada nos estádios V8 e R6, respectivamente. Para lagartas, os resultados indicam maior eficiência do pano-vertical em relação pano-de-batida. Nos menores espaçamentos, o pano-vertical não deixou clara sua maior capacidade de coleta de percevejos, como observado para lagartas. Estes resultados demonstram que são necessárias pesquisas visando a aprofundar a avaliação dos métodos de amostragens de pragas da soja cultivada em diferentes espaçamentos.

    Full Text Available Este artigo analisa dois romances de Rui Mourão, Boca de chafariz e Os demônios descem o morro, com uma base teórica de Walter Benjamin, através de seus conceitos sobre a história, a melancolia, o barroco mineiro, a fantasmagoria. Além de Benjamin, recorremos a algumas ideias pontuais de Luciano de Samósata sobre como escrever história, principalmente sua relação com a verdade e a ficção. Os conceitos dos dois autores teóricos, Benjamin e Luciano, tangenciam-se em alguns pontos e, segundo nosso ponto de vista, favorecem um diálogo, tanto no plano ficcional, como com o histórico, através de figuras de outros séculos, presentes como fantasmas, que também dialogam com nosso presente, tornando os romances polissêmicos, pelo jogo de vozes. O método de leitura é comparativo, já que se articulam valores de duas culturas, vários autores, apresentando revisões da história, sob o olhar contemporâneo.

    Full Text Available Este artigo tem por objetivo analisar o processo de adoção do “sistema privado de ensino” em dois municípios paulistas, tendo em vista a autonomia pedagógica frente à padronização curricular. Nos estudos de dois casos intencionalmente selecionados utiliza-se a metodologia qualitativa constituída pela pesquisa documental e entrevistas semiestruturadas. Inicialmente, discute-se o cenário político nacional que contribuiu para a ampliação das parcerias entre esferas públicas e privadas no campo educacional. Na sequência, apresenta-se, brevemente, a caracterização e a experiência dos municípios no processo de municipalização e de aquisição do material didático, e por fim, discute-se a padronização curricular versus a autonomia pedagógica. Verifica-se que, por mais que, as Secretarias da Educação dos municípios analisado tenham contado com a participação de alguns professores na elaboração do material didático, a autonomia deles no projeto constitui-se numa autonomia regulada tanto pelas gestões públicas e quanto pelas instituições privadas.

  18. Phospholipase C mediates (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI)-, but not lysergic acid diethylamide (LSD)-elicited head bobs in rabbit medial prefrontal cortex.

    The phenethylamine and indoleamine classes of hallucinogens demonstrate distinct pharmacological properties, although they share a serotonin(2A) (5-HT(2A)) receptor mechanism of action (MOA). The 5-HT(2A) receptor signals through phosphatidylinositol (PI) hydrolysis, which is initiated upon activation of phospholipase C (PLC). The role of PI hydrolysis in the effects of hallucinogens remains unclear. In order to better understand the role of PI hydrolysis in the MOA of hallucinogens, the PLC inhibitor, 1-[6-((17β-3-methoxyestra-1,3,5(10)-trien-17-yl)amino)hexyl]-1H-pyrrole-2,5-dione (U73122), was used to study the effects of two hallucinogens, the phenethylamine, (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), and the indoleamine, lysergic acid diethylamide (LSD). PI hydrolysis was quantified through release of [3H]inositol-4-phosphate from living rabbit frontocortical tissue prisms. Head bobs were counted after hallucinogens were infused into the medial prefrontal cortex (mPFC) of rabbits. Both DOI and LSD stimulated PI hydrolysis in frontocortical tissue through activation of PLC. DOI-stimulated PI hydrolysis was blocked by 5-HT(2A/2C) receptor antagonist, ketanserin, whereas the LSD signal was blocked by 5-HT(2B/2C) receptor antagonist, SB206553. When infused into the mPFC, both DOI- and LSD-elicited head bobs. Pretreatment with U73122 blocked DOI-, but not LSD-elicited head bobs. The two hallucinogens investigated were distinct in their activation of the PI hydrolysis signaling pathway. The serotonergic receptors involved with DOI and LSD signals in frontocortical tissue were different. Furthermore, PLC activation in mPFC was necessary for DOI-elicited head bobs, whereas LSD-elicited head bobs were independent of this pathway. These novel findings urge closer investigation into the intracellular mechanism of action of these unique compounds. Published by Elsevier B.V.
