Proposta de um método de ensaio para determinação do volume de azul de metileno adsorvido pela fração fina de solos tropicais / Proposal of a test method for determination of the volume of methylene blue adsorbed by the fine fraction of tropical soils

Andréa de Oliveira Bonini 25 November 2005 (has links)
No Brasil utiliza-se, como técnica de caracterização da fração fina dos solos tropicais, entre outras, o ensaio de adsorção de azul de metileno pelo método da mancha. No entanto, para alguns solos, há dificuldade na identificação do ponto de viragem, ou seja, quando há excesso de corante não adsorvido pelo solo. Assim, apresenta-se neste trabalho uma técnica alternativa para facilitar a determinação do volume de azul de metileno adsorvido por um solo, cujo método é baseado na adição em excesso de azul de metileno à amostra e na titulação de óxido-redução volumétrica (redox) do azul de metileno que não é adsorvido pelo solo. Para a avaliação do ensaio de adsorção de azul de metileno pelo método redox foram ensaiadas 85 amostras de solos e, a partir dos resultados, foram estabelecidos seus graus de atividade que, por sua vez, foram correlacionados com a previsão de comportamento dos solos dada pela MCT. Conclui-se que o procedimento de ensaio proposto é simples e a percepção do ponto de viragem na titulação do excesso de azul de metileno pelo agente oxidante permanganato de potássio é fácil para maioria dos solos, além de apresentar uma boa concordância com os resultados fornecidos pela classificação MCT, permitindo estabelecer, com razoável segurança, a atividade dos argilo-minerais presentes no solo / The methylene blue dye adsorption test (spot test) has been used in Brazil to characterize tropical soil fine fractions. Some soils, however, show difficulties in identifying the test end point, where there is excess of methylene blue in the suspension, not adsorbed by the soil. This work presents an alternative technique to determine the volume of methylene blue adsorbed by a soil, based on the addition of methylene blue in excess to the soil sample and in the determination of the amount of methylene blue that was not adsorbed by the soil through the oxide-reduction (redox) process. For the evaluation of the methylene blue adsorption test (using the redox test), 85 soil samples were tested; their activity levels were established and then correlated with the expected behavior defined by the MCT classification system. The main conclusion of the work is that the proposed method is simple and the identification of the reverse point in the oxide-reduction (redox) process is easy for a majority of soils. The process uses potassium permanganate as the oxidizing agent. It determines, with a great degree of accuracy, the activity levels of the mineral clay portions, showing a significant concordance with the results of the MCT classification system

A Knowledge-Based Approach to Urban-feature Classification Using Aerial Imagery with Airborne LiDAR Data

Huang, Ming-Jer 11 June 2007 (has links)
Multi-spectral Satellite imagery, among remotely sensed data from airborne and spaceborne platforms, contained the NIR band information is the major source for the land- cover classification. The main purpose of aerial imagery is for thematic land-use/land-cover mapping which is rarely used for land cover classification. Recently, the newly developed digital aerial cameras containing NIR band with up to 10cm ultra high resolution makes the land-cover classification using aerial imagery possible. However, because the urban ground objects are so complex, multi-spectral imagery is still not sufficient for urban classification. Problems include the difficulty in discriminating between trees and grass, the misclassification of buildings due to diverse roof compositions and shadow effects, and the misclassification of cars on roads. Recently, aerial LiDAR (ULiUght UDUetection UAUnd URUanging) data have been integrated with remotely sensed data to obtain better classification results. The LiDAR-derived normalized digital surface models (nDSMs) calculated by subtracting digital elevation models (DEMs) from digital surface models (DSMs) becomes an important factor for urban classification. This study proposed an adaptive raw-data-based, surface-based LiDAR data-filtering algorithm to generate DEMs as the foundation of generating the nDSMs. According to the experiment results, the proposed adaptive LiDAR data-filtering algorithm not only successfully filters out ground objects in urban, forest, and mixed land cover areas but also derives DEMs within the LiDAR data measuring accuracy based on the absolute and relative accuracy evaluation experiments results. For the aerial imagery urban classification, this study first conducted maximum likelihood classification (MLC) experiments to identify features suitable for urban classification using LiDAR data and aerial imagery. The addition of LiDAR height data improved the overall accuracy by up to 28 and 18%, respectively, compared to cases with only red¡Vgreen¡Vblue (RGB) and multi-spectral imagery. It concludes that the urban classification is highly dependent on LiDAR height rather than on NIR imagery. To further improve classification, this study proposes a knowledge-based classification system (KBCS) that includes a three-level height, ¡§asphalt road, vegetation, and non-vegetation¡¨ (A¡VV¡VN) classification model, rule-based scheme and knowledge-based correction (KBC). The proposed KBCS improved overall accuracy by 12 and 7% compared to maximum likelihood and object-based classification, respectively. The classification results have superior visual interpretability compared to the MLC classified image. Moreover, the visual details in the KBCS are superior to those of the OBC without involving a selection procedure for optimal segmentation parameters.

Linked Open Projects

Pfeffer, Magnus, Eckert, Kai 28 January 2011 (has links) (PDF)
Semantic Web und Linked Data sind in aller Munde. Nach fast einem Jahrzehnt der Entwicklung der Technologien und Erforschung der Möglichkeiten des Semantic Webs rücken nun die Daten in den Mittelpunk, denn ohne diese wäre das Semantic Web nicht mehr als ein theoretisches Konstrukt. Fast wie das World Wide Web ohne Websites. Bibliotheken besitzen mit Normdaten (PND, SWD) und Titelaufnahmen eine Fülle Daten, die sich zur Befüllung des Semantic Web eignen und teilweise bereits für das Semantic Web aufbereitet und zur Nutzung freigegeben wurden. Die Universitätsbibliothek Mannheim hat sich in zwei verschiedenen Projekten mit der Nutzung solcher Daten befasst – allerdings standen diese zu diesem Zeitpunkt noch nicht als Linked Data zur Verfügung. In einem Projekt ging es um die automatische Erschließung von Publikationen auf der Basis von Abstracts, im anderen Projekt um die automatische Klassifikation von Publikationen auf der Basis von Titeldaten. Im Rahmen dieses Beitrags stellen wir die Ergebnisse der Projekte kurz vor, möchten aber im Schwerpunkt auf einen Nebenaspekt eingehen, der sich erst im Laufe dieser Projekte herauskristallisiert hat: Wie kann man die gewonnenen Ergebnisse dauerhaft und sinnvoll zur Nachnutzung durch Dritte präsentieren? Soviel vorweg: Beide Verfahren können und wollen einen Bibliothekar nicht ersetzen. Die Einsatzmöglichkeiten der generierten Daten sind vielfältig. Konkrete Einsätze, zum Beispiel das Einspielen in einen Verbundkatalog, sind aber aufgrund der Qualität und mangelnden Kontrolle der Daten umstritten. Die Bereitstellung dieser Daten als Linked Data im Semantic Web ist da eine naheliegende Lösung – jeder, der die Ergebnisse nachnutzen möchte, kann das tun, ohne dass ein bestehender Datenbestand damit kompromittiert werden könnte. Diese Herangehensweise wirft aber neue Fragen auf, nicht zuletzt auch nach der Identifizierbarkeit der Ursprungsdaten über URIs, wenn diese (noch) nicht als Linked Data zur Verfügung stehen. Daneben erfordert die Bereitstellung von Ergebnisdaten aber auch weitere Maßnahmen, die über die gängige Praxis von Linked Data hinaus gehen: Die Bereitstellung von Zusatzinformationen, die die Quelle und das Zustandekommen dieser Daten näher beschreiben (Provenienzinformationen), aber auch weitere Informationen, die über das zugrunde liegende Metadatenschema meist hinausgehen, wie Konfidenzwerte im Falle eines automatischen Verfahrens der Datenerzeugung. Dazu präsentieren wir Ansätze auf Basis von RDF Reification und Named Graphs und schildern die aktuellen Entwicklungen auf diesem Gebiet, wie sie zum Beispiel in der Provenance Incubator Group des W3C und in Arbeitsgruppen der Dublin Core Metadaten-Initiative diskutiert werden.

Úloha sestry při adaptaci novorozence po porodu / Role of the midwife in adaptation of the newborn after the birth.

MATÝSOVÁ, Monika January 2017 (has links)
This diploma thesis deals with the role of the child nurse in the adaptation of the newborn after delivery.In the theoretical part we devote to the available scientific knowledge focused on the course of pregnancy, the way of giving birth (vaginal and operative), assessment of postnatal adaptation of the newborn, breastfeeding and its importance. The essential part is mapping the role of child nurse in newborn care using the NOC system to evaluate their postnatal adaptation. The Czech and foreign literary sources were used for the theoretical part of the diploma thesis. The first aim of the diploma thesis was a detailed mapping of the role of the child nurse in postnatal adaptation of the newborn after physiological and operative delivery. Two research questions have been selected for its solution. The first research question was, what Apgar values the newborns show after the physiological and operative delivery. The second research question was the success of the first application of the newborn to breastfeeding within 30 minutes after physiological and operative delivery. The second aim of this diploma thesis was to verify the classification of the NOC on the evaluation of the newborn adaptation. For the solution, a research question has been determined, what is the opinion of nurses on the use of the NOC classification system in postnatal adaptation. For the empirical part of the research we have chosen a qualitatively quantitative strategy. Observation, individual semi-structured interviews with nurses and written filling of NOC classification system forms were used for data collection. The first research group was 10 newborns after the physiological - vaginal delivery and 10 newborns after the operative delivery by Caesarean section. The second research group consisted of 2 child nurses working with neonates as part of postnatal adaptation in Hospital Jihlava. Analyzing and interpreting the obtained results, we found out that newborns born by vaginal delivery had an average Apgar score of 8.03 and newborns born by Caesarean section had an average Apgar score of 9.50. The average values of the indicators in the NOC classification system code 0118 The adaptation of the newborn showed slightly poorer results after vaginal deliveries. Two groups of newborns that we followed did not match the generally expected results. Newborns after the Caesarean section are threatened by risk factors, but due to careful nursing care and gentle childbirth, such a risk does not occur and the process of postnatal adaptation can be successful. In the NOC classification system code 1000 Beginning of breastfeeding child showed the indicators at vaginal deliveries, at least 8 feedings per day and infant satisfaction after feeding, better results. In the NOC classification system code 1001 Beginning of breastfeeding mother the average values of breast suction indicators and satisfaction with the breastfeeding process resulted better in favour of neonates born vaginally compared to neonates after Caesarean section. As regards the success of the first feeding of neonates to breastfeeding within 30 minutes after delivery, a clearly superior result was obtained for newborns born vaginally. The conclusions drawn from our research in relation to child breastfeeding by mother confirm the clear benefit of vaginal births for the successful adaptation of newborns. A child nurse undoubtedly plays an important role in the assessment of postnatal adaptation of the newborn. The research of the diploma thesis shows that the classification system NOC is very well sophisticated in the context of a newborn adaptation and it is even detailed in connection with the follow-up and subsequent provision of newborn care. Its full use in current practice in the established care system of particular healthcare facilities is not possible due to insufficient staffing of the department. The existing documentation system does not provide reserves

Creative Disability Classification Systems : The case of Greece, 1990-2015

Pavli, Antonia January 2017 (has links)
Disability classification systems belong to the core of states’ social/disability policies through which persons with disabilities are classified as eligible or ineligible for having access to disability allowances. The study of disability classification systems has stimulated the interest of several scholars from the broader area of disability studies. Either by conducting comparative studies between different states and describing the similarities and differences of these systems around the world or by conducting studies focusing on the politics and semantics in the development of disability classification systems in specific states, all studies have shown a pluralism in the systems for assessing and certifying disability. In Greece, the development of disability classification systems for social welfare reasons emerged as a controversy that lasted for almost twenty years. One factor that strengthened the controversy was the outbreak of the economic crisis late in 2009 followed by the announcement by the governmental authorities of the enactment of a new system for assessing and certifying disability as part of the austeritydriven policies that the Greek state would enact for facing the consequences of the economic crisis. Drawing on an interdisciplinary approach, the overall aim of this study is to describe and analyze the enactment of disability classification systems in the context of Greek social policy from 1990 to 2015. For the collection of empirical material, a qualitative research method was employed, consisting of interviews, written material, and newspaper articles. The main findings of this thesis are: I) the involvement of the political parties in the development of the systems for certifying and assessing disability; II) the involvement of the disability movement in policymaking; III) the “creative” use of statistics by governmental authorities for the enactment of disability/social policies; IV) how the concept of “disability fraud” has been constructed as a “threat” to the society; and V) the vulnerability of disability classification systems in times of austerity.

The use of the DWV3 classification system in manufacturing companies for evaluating a market-specific supply chain strategy - A case study at Atlas Copco Industrial Technique

Planting, Ralf January 2012 (has links)
The research topic of this study is market-specific supply chain strategy, and the research problem is defined as, how manufacturing companies can use the DWV3 classification system to evaluate the opportunity for a market-specific supply chain strategy. What has been written about the DWV3 classification system is somewhat general in its nature and the practitioner is left without detailed instructions on how to proceed with the analytical analysis. Key elements of the DWV3 classification system that is not explicitly described in the literature is (1) how to measure each of the classification variables, (2) how to define a suitable limit for each measure in order to classify the products and (3) how to reason when sequencing the classification variables in the clustering analysis. Hence, the purpose of this thesis is to make the DWV3 classification system more available to practitioners, and thus the aim is to illustrate how to tackle the key elements of the framework by applying it on the Atlas Copco Industrial Technique Business Area product portfolio. A single-case study design was chosen as a suitable research approach for this thesis. The application of the DWV3 system to the ITBA product portfolio was considered as the phenomenon under investigation, the case, of this study. Two sets of quantitative data were collected, demand data and product master data. The qualitative data collected was related to the ITBA supply chain set-up and the products as well as the customers’ responsiveness requirements for each assortment included in the study. All qualitative data was collected through interviews. The findings of this study are summarized in a number of conclusions that can serve as guidelines for practitioners that are about to apply the DWV3 system. These are (1) as far as possible use measures at the single product level, (2) use measures that express each classification variable in a way that is relevant to the matching of demand characteristics and supply chain strategy, (3) be prepared to redefine initial measures in order to describe the studied products’ characteristics in the best possible way, (4) develop measures that are based on available data or data that is feasible to attain, (5) adjust the number of codification levels to find the best trade-off between the level of detail in the cluster analysis and the number of populated segments, (6) alter the sequencing and repeat the cluster analysis to gain insight into the demand characteristics of the product portfolio, (7) the final sequencing of the classification variables must produce clusters that are relevant for the chosen production philosophy concepts.

Assessing the healthcare quality issues for digital incident reporting in Sweden: Incident reports analysis

Rahman Jabin, Md Shafiqur, Steen, Mary, Wepa, Dianne, Bergman, Patrick 08 May 2023 (has links)
Yes / This study explored healthcare quality issues affecting the reporting and investigation levels of digital incident reporting systems. Methods: A total of 38 health information technology-related incident reports (free-text narratives) were collected from one of Sweden’s national incident reporting repositories. The incidents were analysed using an existing framework, i.e., the Health Information Technology Classification System, to identify the types of issues and consequences. The framework was applied in two fields, ‘event description’ by the reporters and ‘manufacturer’s measures’, to assess the quality of reporting incidents by the reporters. Additionally, the contributing factors, i.e., either human or technical factors for both fields, were identified to evaluate the quality of the reported incidents. Results: Five types of issues were identified and changes made between before-and-after investigations: Machine to software- related issues (n = 8), machine to use-related issues (n = 5), software to software-related issues (n = 5), use to software- related issues (n = 4) and use to use-related issues (n = 1). Over two-thirds (n = 15) of the incidents demonstrated a change in the contributing factors after the investigation. Only four incidents were identified as altering the consequences after the investigation. Conclusion: This study shed some light on the issues of incident reporting and the gap between the reporting and investigation levels. Facilitating sufficient staff training sessions, agreeing on common terms for health information technology systems, refining the existing classifications systems, enforcing mini-root cause analysis, and ensuring unit-based local reporting and standard national reporting may help bridge the gap between reporting and investigation levels in digital incident reporting.
