Sintaxe e semântica de registros bibliográficos: princípios para a conversão de registros analógicos para o formato MARC21 bibliográfico: Scan for MARC

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

Comparação entre métodos e análise de correntes de curto-circuito

Overcurrents may endanger the whole electrical system and living beings, they are the result of short circuits and failures that can occur in electrical systems, no matter how well designed they are. Therefore it is important to predict these failures with analysis of electrical systems to make it possible to design appropriate protections, to ensure that those intervene properly and avoid technical and mainly human losses. However there is no standard for calculation of the short circuit currents, the main authors of the national literature about the subject suggest various methods, knowing the particularities among them provides quick and easy choice and proper application of them. To do so, a base case from an electrical system that presents a short circuit is chosen, which will be analyzed using the methods presented

Tecnologia e poder: uma análise dos cadernos de informática dos jornais Folha e Estado de São Paulo

O advento de uma nova ordem global mediada pelas tecnologias de informação e comunicação pode parecer, a um observador desatento, algo bom ou, no mínimo, neutro. No entanto, os valores decorrentes deste modelo organizacional estão intimamente ligados a interesses políticos, econômicos e ideológicos. Entender a complexidade dessa nova dinâmica em nossas vidas, sem cair nos extremismos da questão, é o desafio a que nos propomos. Para tanto, discutiremos no primeiro a relação entre tecnologia e sociedade desde o advento do alfabeto ocidental. No segundo capítulo apresentaremos os fundamentos da análise do discurso de linha francesa e, no terceiro capítulo, analisaremos os cadernos de informática do mês de agosto de dois grandes jornais impressos brasileiros – Folha e Estado de São Paulo - à luz das teorias da análise do discurso, buscando entender como a construção simbólica de nosso atual contexto se manifesta na forma discursiva do jornalismo

Estudo hodológico das aferências ao primeiro núcleo do circuito neural do reflexo auditivo de sobressalto: núcleo da raiz coclear

Las neuronas de la raíz coclear son las primeras neuronas del sistema nervioso central a recibir la información auditiva proveniente de la cóclea y se conectan con centros de integración sensoriomotora del tronco encefálico, especialmente con el núcleo reticular caudal del puente. Funcionalmente las neuronas de la raíz coclear están envueltos en el circuito elemental del reflejo auditivo de sobresalto juntamente con las células ganglionares del órgano de Corti, el núcleo reticular caudal del puente y las motoneuronas de la médula espinal. El reflejo auditivo de sobresalto presenta una serie de modulaciones como la habituación, la sensibilización, la inhibición por estímulo previo y la potenciación por un estímulo adverso. Las alteraciones en la reacción refleja de sobresalto y sus diferentes modulaciones poseen valor diagnóstico en la clínica médica de enfermedades neurodegenerativas y psiquiátricas como Parkinson y Esquizofrenia. Las modulaciones del reflejo auditivo de sobresalto ocurren mediante la influencia de diversos núcleos sobre los componentes del circuito elemental de este reflejo. El núcleo menos estudiado del circuito neural del reflejo auditivo de sobresalto es el núcleo de la raíz coclear. El patrón de conectividad eferente de las neuronas de la raíz coclear es bien conocido, sin embargo poco se conoce sobre los orígenes de sus aferencias y la identidad neuroquímica de las mismas. Estudios previos demostraron que el soma y en las dendritas de las neuronas de la raíz coclear están cubiertos por botones sinápticos de cuatro tipos, sugiriendo que existan diversos orígenes para estos terminales axonales, con características neuroquímicas propias. El conocimiento de las aferencias a las neuronas de la raíz coclear es relevante para comprender cual el papel del núcleo de la raíz coclear en las modulaciones del reflejo auditivo de sobresalto. Por lo tanto, ...

Desenvolvimento e validação de uma técnica quantitativa de análise de imagem para avaliação do teste do cometa corado pela prata

The comet assay is a method of DNA damage analysis widely used to quantify oxidative damage, crosslinks of DNA, apoptosis and genotoxicity of chemicals substances as chemical, pharmaceuticals, agrochemicals products, among others. This technique is suitable to detect DNA strand breaks, alkali-labile sites and incomplete excision repair sites and is based on the migration of DNA fragments by microeletroforesis, DNA migrates for the anode forming a “tail”, and the formed image has the appearance of a comet. The slides can be stained with fluorescence or silver, having differences in the microscopy type used for the analysis and the possibility of storage of the slides, moreover, the first one is a stained-method with more difficulties of accomplishment. The image analysis can be performed by a visual way, however, there is a disadvantage as the subjectivity on the results, that can be minimized by an automated method of digital analysis. This process was studied in this report with the aim to perceive the validation of the digital analysis turning it a quantitative method with larger reproductibility, minimizing the variability and imprecision due to the subjective analysis. For this validation we selected 50 comets photographed in a standardized way and printed, afterwards, pictures were submitted to three experienced appraisers, who quantified them manually. Later, the images were processed by free software ImageJ 1.38x, printed and quantified manually by the same appraisers. The intraclass correlation was higher to comet measures after image processing. Following, an algorithm of automated digital analysis from the measures of the comet was developed; the values obtained were compared with those 12 estimated manually after the processing resulting high correlation among the measures. The use of image analysis systems increases ...(Complete abstract click electronic access below)

Incorporação de um sistema nobreak com ultracapacitor em um microcomputador

The objective of this work is to analyze the viability of incorporation in a microcomputer box of a nobreak with an ultracapacitor as energy storage device, substituting the conventional chemical battery. An advantage of this inclusion is cost reduction because a specific metallic or plastic frame won’t be necessary to protect the components of the nobreak; the microcomputer metallic frame offers the necessary protection for both equipments. Moreover, a large quantity of internal space of microcomputers box isn’t used, and is possible to use it to wrap up the nobreak. This work uses data about average power consumption of microcomputers; operation of switching mode power supplies for microcomputers; electrical and mechanical characteristics of ultracapacitors and operation of power circuits of nobreaks, with the purpose of present a study of energy storage capacity that an ultracapacitor should have to allow a safe switching off of a microcomputer in case of electrical network fail. It was noticed that the use of ultracapacitors is feasible to feed an 180 W load for 75 s, using a capacitive bank with sixteen ultracapacitors, with a total capacitance of 350 F and voltage of 10,8 V. The use of the proposed nobreak increases the reliability of the microcomputer by reducing the probability of user data losses in case of an electrical network fail, offering a high cost/benefit product. The substitution of the battery by an ultracapacitor allows a quick nobreak recharge, with low maintenance costs, since ultracapacitors have a lifetime bigger than batteries; beyond reducing the environmental impact, because they don’t use potentially toxic chemical compounds
