Bone structure assessed by HR-pQCT, TBS and DXL in adult patients with different types of osteogenesis imperfecta.

UNLABELLED: Bone microarchitecture by high-resolution peripheral quantitative computed tomography (HR-pQCT) was assessed in adult patients with mild, moderate, and severe osteogenesis imperfecta (OI). The trabecular bone score (TBS), bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA), and dual X-ray and laser (DXL) at the calcaneus were likewise assessed in patients with OI. Trabecular microstructure and BMD in particular were severely altered in patients with OI. INTRODUCTION: OI is characterized by high fracture risk but not necessarily by low BMD. The main purpose of this study was to assess bone microarchitecture and BMD at different skeletal sites in different types of OI. METHODS: HR-pQCT was performed in 30 patients with OI (mild OI-I, n = 18 (41.8 [34.7, 55.7] years) and moderate to severe OI-III-IV, n = 12 (47.6 [35.3, 58.4] years)) and 30 healthy age-matched controls. TBS, BMD by DXA at the lumbar spine and hip, as well as BMD by DXL at the calcaneus were likewise assessed in patients with OI only. RESULTS: At the radius, significantly lower trabecular parameters including BV/TV (p = 0.01 and p < 0.0001, respectively) and trabecular number (p < 0.0001 and p < 0.0001, respectively) as well as an increased inhomogeneity of the trabecular network (p < 0.0001 and p < 0.0001, respectively) were observed in OI-I and OI-III-IV in comparison to the control group. Similar results for trabecular parameters were found at the tibia. Microstructural parameters were worse in OI-III-IV than in OI-I. No significant differences were found in cortical thickness and cortical porosity between the three subgroups at the radius. The cortical thickness of the tibia was thinner in OI-I (p < 0.001), but not OI-III-IV, when compared to controls. CONCLUSIONS: Trabecular BMD and trabecular bone microstructure in particular are severely altered in patients with clinical OI-I and OI-III-IV. Low TBS and DXL and their significant associations to HR-pQCT parameters of trabecular bone support this conclusion.

Guidelines for CERIF-XML Data Exchange with CSUC’s Catalan Research Portal (PRC) (Version 2.2)

The Catalan Research Portal (Portal de la Recerca de Catalunya or PRC) is an initiative carried out by the Consortium for University Services in Catalonia (CSUC) in coordination with nearly all universities in Catalonia. The Portal will provide an online CERIF-compliant collection of all research outputs produced by Catalan HEIs together with an appropriate contextual information describing the specific environment where the output was generated (such as researchers, research group, research project, etc). The initial emphasis of the Catalan Research Portal approach to research outputs will be made on publications, but other outputs such as patents and eventually research data will eventually be addressed as well. These guidelines provide information for PRC data providers to expose and exchange their research information metadata in CERIFXML compatible structure, thus allowing them not just to exchange validated CERIF XML data with the PRC platform, but to improve their general interoperability by being able to deliver CERIFcompatible outputs.

Perfil químico de cultivares de feijão (phaseolus vulgaris) pela técnica de high resolution magic angle spinning (HR-MAS)

The application of one-dimensional proton high-resolution magic angle spinning (¹H HR-MAS) NMR combined with a typical advantages of solid and liquid-state NMR techniques was used as input variables for the multivariate statistical analysis. In this paper, different cultivars of beans (Phaseolus vulgaris) developed and in development by Embrapa - Arroz e Feijão were analyzed by ¹H HR-MAS, which have been demonstrated to be a valuable tool in its differentiation according chemical composition and avoid the manipulation of the samples as used in other techniques.

XML-tekniikoihin perustuva ajurimalli LabView-pohjaiseen testausympäristöön

XML-muotoista tiedonesitystapaa hyödynnetään yhä enemmän esitettäessä rakenteellista tietoa. Tarkoituksena on antaa yleishyödyllinen ja uudelleenkäytettävä tapa jakaa yleistä tietoa erilaisten rajapintojen yli. XML-tekniikoita käytetään myös korjaamaan aiemmin tehdyissä sovellutuksissa esiintyneitä puutteita ja parantamaan niiden toimintaa. Tässä diplomityössä esitellään Telestelle LabView-pohjaiseen testaussovellusympäristöön suunniteltava ajuriuudistus. Työssä paranneltiin aiempaa ajurimallia soveltamalla siihen XML-tekniikoita hyödyntäviä toimintoja. Tarkoituksena oli vähentää testaussovelluskehityksessä vaadittavaa ohjelmointityötä korvaamalla sovelluksiin kovakoodatut ominaisuudet XML-pohjaisilla konfiguraatiotiedostoilla. Järjestelmän pohjana on yleiskäyttöinen ajuri, joka käyttää Telesten omaa EMS-protokollaa kommunikoinnissaan testattavien tuotteiden kanssa. Ajurimalli käyttää XML-pohjaisia konfiguraatiotiedostoja määrittelemään testattavien tuotteiden ominaisuuksia. XML-skeematiedostoilla esitetään ajurin käyttämän kommunikaatioprotokollan viestityypit ja niiden rakenteet. Työn tuloksena onnistuttiin luomaan uudenlainen XML-tekniikoita hyödyntävä ajurimalli. Yhteen yhteiseen ajuriin perustuva malli yhdenmukaistaa testaussovelluksien toteuttamista ja vähentää tarvittavaa ohjelmointityötä. Ajurin käyttöä helpotettiin toteuttamalla testaussovelluksien kehitysympäristöön erityinen editori, jolla voidaan helposti luoda ajuria käyttäviä toimintoja.

Visualization of communication system testing logs

During the past decades testing has matured from ad-hoc activity into being an integral part of the development process. The benefits of testing are obvious for modern communication systems, which operate in heterogeneous environments amongst devices from various manufacturers. The increased demand for testing also creates demand for tools and technologies that support and automate testing activities. This thesis discusses applicability of visualization techniques in the result analysis part of the testing process. Particularly, the primary focus of this work is visualization of test execution logs produced by a TTCN-3 test system. TTCN-3 is an internationally standardized test specification and implementation language. The TTCN-3 standard suite includes specification of a test logging interface and a graphical presentation format, but no immediate relationship between them. This thesis presents a technique for mapping the log events to the graphical presentation format along with a concrete implementation, which is integrated with the Eclipse Platform and the OpenTTCN Tester toolchain. Results of this work indicate that for majority of the log events, a visual representation may be derived from the TTCN-3 standard suite. The remaining events were analysed and three categories relevant in either log analysis or implementation of the visualization tool were identified: events indicating insertion of something into the incoming queue of a port, events indicating a mismatch and events describing the control flow during the execution. Applicability of the results is limited into the domain of TTCN-3, but the developed mapping and the implementation may be utilized with any TTCN-3 tool that is able to produce the execution log in the standardized XML format.

Exploring potentialities of the HR-CS FAAS technique in the determination of Ni and Pb in mineral waters

National Health Surveillance Agency (ANVISA) established in the decree number 54 maximum allowed levels for Ni and Pb in mineral and natural waters at 20 µg L-1 and 10 µg L-1, respectively. For screening analysis purposes, the high-resolution continuum source flame atomic absorption spectrometry technique (HR-CS FAAS) was evaluated for the fast-sequential determination of nickel and lead in mineral waters.Two atomic lines for Ni (232.003 nm - main and 341.477 nm - secondary) and Pb (217.0005 nm - main and 283.306 nm - secondary) at different wavelength integrated absorbance (number of pixels) were evaluated. Sensitivity enhanced with the increase of the number of pixels and with the summation of the atomic lines absorbances. The main figures of merit associated to the HR-CS FAAS technique were compared with that obtained by line-source flame atomic absorption spectrometry (LS FAAS). Water samples were pre-concentrated about 5-fold by evaporation before analysis. Recoveries of Pb significantly varied with increased wavelength integrated absorbance. Better recoveries (92-93%) were observed for higher number of pixels at the main line or summating the atomic lines (90-92%). This influence was irrelevant for Ni, and recoveries in the 92-104% range were obtained in all situations.

INTERAÇÃO GENÓTIPOS X AMBIENTES PARA PRODUTIVIDADE DE CLONES DE Eucalyptus L'Hér. NO ESTADO DO RIO GRANDE DO SUL

Este trabalho objetivou estudar a interação genótipos em ambientes de clones de Eucalyptus em quatro ambientes do Estado do Rio Grande do Sul. Os ensaios foram conduzidos nas áreas da empresa CMPC Celulose Riograndense, nos Municípios de Minas do Leão (Horto Florestal Cambará), Encruzilhada do Sul (Horto Florestal Capivara), Dom Feliciano (Horto Florestal Fortaleza) e Vila Nova do Sul (Horto Florestal São João). No ano 2007, foi implantada uma rede de testes clonais com 864 clones de Eucalyptus, pertencentes a 37 espécies e híbridos. Aos 3 anos de idade, foram mensurados o diâmetro à altura do peito (dap) e a altura total (Ht) das árvores dos experimentos. O incremento médio anual (IMA) foi calculado de acordo com o volume individual por clone e o estande de plantas por hectare na idade de avaliação do teste clonal. Os resultados da correlação genotípica entre os ambientes variaram de 0,39 a 0,56, demonstrando que ocorreu interação genótipos x ambientes significativa dos caracteres avaliados. Esses resultados indicam que é necessário selecionar clones específicos, nas combinações de ambientes com baixa correlação genética entre si. Ocorreu baixa correção genética entre os ambientes Cambará x Capivara; Cambará x São João; Capivara x Fortaleza; Capivara x São João; e Fortaleza x São João. Dessa maneira, para este estudo foram necessárias três unidades de manejo para minimizar os efeitos da interação genótipos x ambientes. Incluindo a seleção por estabilidade, adaptabilidade e os dois atributos simultaneamente, ocorreu mudança de clones e de posição entre os clones no ordenamento de seleção. Com a seleção simultânea por estabilidade e adaptabilidade (MHPRVG), os ganhos aumentaram em comparação com a seleção pelos valores genotípicos preditos entre os ambientes, principalmente, e houve incremento dos ganhos em relação à testemunha comercial. Por exemplo, os cinco melhores clones pelo critério MHPRVG apresentaram-se 56% superiores à testemunha comercial para a característica produtividade em volume.
