VMEXT: A Visualization Tool for Mathematical Expression Trees

Mathematical expressions can be represented as a tree consisting of terminal symbols, such as identifiers or numbers (leaf nodes), and functions or operators (non-leaf nodes). Expression trees are an important mechanism for storing and processing mathematical expressions as well as the most frequently used visualization of the structure of mathematical expressions. Typically, researchers and practitioners manually visualize expression trees using general-purpose tools. This approach is laborious, redundant, and error-prone. Manual visualizations represent a user's notion of what the markup of an expression should be, but not necessarily what the actual markup is. This paper presents VMEXT - a free and open source tool to directly visualize expression trees from parallel MathML. VMEXT simultaneously visualizes the presentation elements and the semantic structure of mathematical expressions to enable users to quickly spot deficiencies in the Content MathML markup that does not affect the presentation of the expression. Identifying such discrepancies previously required reading the verbose and complex MathML markup. VMEXT also allows one to visualize similar and identical elements of two expressions. Visualizing expression similarity can support support developers in designing retrieval approaches and enable improved interaction concepts for users of mathematical information retrieval systems. We demonstrate VMEXT's visualizations in two web-based applications. The first application presents the visualizations alone. The second application shows a possible integration of the visualizations in systems for mathematical knowledge management and mathematical information retrieval. The application converts LaTeX input to parallel MathML, computes basic similarity measures for mathematical expressions, and visualizes the results using VMEXT.Comment: 15 pages, 4 figures, Intelligent Computer Mathematics - 10th International Conference CICM 2017, Edinburgh, UK, July 17-21, 2017, Proceeding

Pengaruh Konsentrasi Completion Fluid terhadap Laju Swelling Clay pada Sumur Produksi Minyak Bumi

In the process of oil production wells maintenance, sometimes it has to face containing mud (clay) formations and this situation can detain the process of well maintenance and damage downhole equipment, especially pumps because of clay swelling. This study intends to determine the concentration effect of completion fluid to clay swelling and determine the optimum completion fluid concentration In this study, KCl and XCD polymer has been chosen as the inhibiting compound of clay swelling. Concentration used is 2%, 4% and 6% for KCl, 2, 3 and 4 ppm for XCD polymer with a ratio between the solution with the clay is 1:8, 1 9 and 1:10. The temperature used is room temperature of 25° C. The results showed that the rate of swelling occurs most rapidly at 2% KCl ratio of 1:8. The phenomenon of swelling clay to a solution of XCD polymer is very small so it can be considered no swelling that occurs, either in 2, 3 or 4 ppm solution of polymer XC

Rapid detection of Mycobacterium ulcerans with isothermal recombinase polymerase amplification assay.

Background Access to an accurate diagnostic test for Buruli ulcer (BU) is a research priority according to the World Health Organization. Nucleic acid amplification of insertion sequence IS2404 by polymerase chain reaction (PCR) is the most sensitive and specific method to detect Mycobacterium ulcerans (M. ulcerans), the causative agent of BU. However, PCR is not always available in endemic communities in Africa due to its cost and technological sophistication. Isothermal DNA amplification systems such as the recombinase polymerase amplification (RPA) have emerged as a molecular diagnostic tool with similar accuracy to PCR but having the advantage of amplifying a template DNA at a constant lower temperature in a shorter time. The aim of this study was to develop RPA for the detection of M. ulcerans and evaluate its use in Buruli ulcer disease. Methodology and principal findings A specific fragment of IS2404 of M. ulcerans was amplified within 15 minutes at a constant 42°C using RPA method. The detection limit was 45 copies of IS2404 molecular DNA standard per reaction. The assay was highly specific as all 7 strains of M. ulcerans tested were detected, and no cross reactivity was observed to other mycobacteria or clinically relevant bacteria species. The clinical performance of the M. ulcerans (Mu-RPA) assay was evaluated using DNA extracted from fine needle aspirates or swabs taken from 67 patients in whom BU was suspected and 12 patients with clinically confirmed non-BU lesions. All results were compared to a highly sensitive real-time PCR. The clinical specificity of the Mu-RPA assay was 100% (95% CI, 84–100), whiles the sensitivity was 88% (95% CI, 77–95). Conclusion The Mu-RPA assay represents an alternative to PCR, especially in areas with limited infrastructure. Author summary Current diagnostic methods to detect M. ulcerans suffer from delayed time-to-results in most endemic countries by the prolonged period of time for the shipment and storage of samples to a distant, centralized laboratory. The M. ulcerans recombinase polymerase amplification assay (Mu-RPA) is a new, rapid diagnostic test developed for the detection of M. ulcerans infection, known commonly as Buruli ulcer, a chronic, debilitating, necrotizing disease of the skin and soft tissues. This assay is suitable for use on a portable detection device, with the potential to be used for quick diagnosis at the point of need, providing timely results to health workers at Buruli ulcer treatment clinics

Relatório de estágio do mestrado em Ensino da Educação Física nos Ensinos Básico e Secundário, apresentado à Faculdade de Ciências do Desporto e Educação Física da Universidade de CoimbraEste relatório final surge a conclusão de uma formação de dois anos neste mestrado. O Estágio Pedagógico foi realizado na Escola Secundária de Anadia junto da turma D do 9º ano de escolaridade, durante o ano lectivo de 2013/14. O presente trabalho, pretende relatar e refletir sobre os procedimentos adotados em três processos por mim considerados fundamentais no processo ensino-aprendizagem, o planeamento; a realização e a avaliação. Ao longo do ano lectivo a reflexão constante sobre a prática pedagógica permitiu que me torna-se um professor em constante evolução, absorvendo a informação e tendo uma postura critica em relação a este processo. Com este relatório pretendo demonstrar o processo desenvolvido ao longo desta jornada. Um dos principais desfechos que retiro deste processo é a necessidade de ensinar e promover a aprendizagem adequada a todos os alunos. Deste o aluno que tem excesso de peso, ao que tem Necessidades Educativas Especiais, ao que não gosta de educação física, estre outros perfis. Se lhes for apresentado um ambiente adequado às suas necessidades todos eles serão munidos de uma importante bagagem. O estágio pedagógico promove a aquisição de um conjunto de saberes, de atitudes práticas e resolução de problemas pedagógicos, que servirão como base de sustentação para a integração futura no ensino e também será transversal a outras actividades ligadas ao desporto e à promoção de saúde. Por último, será abordado o tema: grupos de nível em Educação Física, apresentando como exemplo a turma do 9ºD. Que se foi confrontada ao longo do ano lectivos pela homo e heterogeneidade nos grupos formados para a aula. This final report is the conclusion of a two-year training in this Masters Degree. The Pedagogical Internship was conducted in Escola Secundária de Anadia with class D of the 9th grade during the school year 2013/14. The present study aims to report and reflect on the procedures adopted in the three cases, that i considered fundamental, teaching-learning process, planning; the implementation and evaluation. During the school year, constant reflexion about pedagogical act allow me toi became a teacher in constant improvement, absorbing all the information with na critic posture about the teaching. With this report i pretend show all the process developed during this long journey. One of the principals knowledges i reatret from this process is the need of teaching and promote na learning suitable for all students. From the student who have overweight, the one who has Special Educational Needs, the student who don’t like physical education, until the other students profile, if we gave them an suitable environment to their needs, al og them will todos eles will be provided with an important baggage. The Pedagogical Internship promotes the acquisition of an a aquisição de a set of knowledge, with practices and attitudes for solving pedagogical problems, to serve as a support base for future integration in teaching and will also be cross-linked to other activities for sport and health promotion.. Last but not least, will be approach a theme: Group levels on physical Education class, using as an example the class D from the 9th grade . Who was faced throughout the school year by the homo-and heterogeneity in groups formed for class
