Uma experiência didática de inserção do microcomputador como instrumento de medida no laboratório de física do ensino médio

Neste trabalho elaboramos cinco atividades experimentais que envolvem o uso do microcomputador como instrumento de medida no laboratório didático de Física. As atividades são do tipo aberto, de modo que os alunos tenham a oportunidade de explorar, testar e discutir soluções para todo o processo de medida, desde o uso de sensores nos sistemas de detecção, à conversão analógica/digital, passando pelos softwares. Somente depois de medidas manuais, o aluno passa à aquisição automática. Há guias impressos para alunos, com questões, desafios e sugestões de tarefas a serem executadas, e um texto de apoio para professores, contendo embasamento teórico e técnico indispensáveis para a compreensão do processo de aquisição automática. Os tópicos tratados são: sensores, medidas de tempo, e ondas mecânicas transversais (em cordas) e longitudinais (sonoras). O embasamento teórico para o desenvolvimento da proposta está apoiado na teoria sócio-interacionista de Vigotsky, na qual o desenvolvimento cognitivo não pode ser entendido sem referência ao contexto social, seus signos e instrumentos. Todas atividades foram testadas em condições de sala de aula em turmas de ensino médio e tecnológico da Unidade de Ensino do CEFET/RS, em 2003, e no curso de extensão Física para o Ensino Médio II, do Instituto de Física da UFRGS, em 2004. O produto educacional deste trabalho consiste em um texto de apoio para professores do ensino médio sobre o uso do microcomputador como um instrumento de medida, guias para alunos das cinco atividades experimentais envolvendo aquisição automática de dados e um hipertexto, disponível na web, baseado em animações do tipo Java Applet (Physlet).

Entre orquídeas e girassóis :o laboratório de Enfermagem na visão de estudantes

To study the teaching/learning process about the Nursing procedures carried out in the laboratory, and learn both the sapiens and the demens dimensions of such process, is the main purpose of this study. The objectives are to: identify the major laboratory contributions to the teaching/learning process from the point of view of undergraduate students and the feelings they express; describe the difficulties they have identified; and analyze the relevance of the laboratory to this process. As part of the inquiry procedure, four core group meetings were held with 26 undergraduate students who had completed the course on Semiology and Semiotics in Nursing, which is the course where the Nursing laboratory is most needed as a learning space. The analysis, based on a qualitative approach, had as fundamental theoretical support studies made by Friedlander and Hayashida, who deal with learning/teaching in the Nursing laboratory, and by authors who favor humanization in teaching such as, among others, Freire, Maturana, Morin, Assmann. Results point toward the relevance of the Nursing laboratory as a facilitator for the learning/teaching process. In their speech the students repeatedly state that the development of procedures in simulated situations enable them to become more self-assured and technically prepared for caring. In addition, they emphasize that feelings such as fear, lack of confidence, anxiety, anguish and panic become diminished at the time of their clinic experience when they have had previous learning in the laboratory. They have also acknowledged that some difficulties of structural nature have become obstacles to a high-quality learning development. In summary, in spite of the difficulties that have been pointed out by the students concerning the use of the Nursing laboratory in the learning/teaching process, they also recognize that this is the locus par excellence where they can develop their skills and appease their anxieties

The Oil Measurement Evaluation Laboratory (LAMP), located in the Federal University of Rio Grande do Norte (UFRN), has as main goal to evaluate flow and BS&W meters, where the simulation of a bigger number of operation variable in field, guarantees a less uncertain evaluation. The objective of this work is to purpose a heating system design and implementation, which will control the temperature safely and efficiently in order to evaluate and measure it. Temperature is one of the variables which influence the flow and BS&W accurate measurement, directly affecting the fluid viscosity and density in the experiment. To project the heating system it is of great importance to take the laboratory requirements, conditions and current restrictions into consideration. Three alternatives were evaluated: heat exchanger, internal resistance and external resistance. After the analyses are made in order to choose the best alternative for the heating system in the laboratory, control strategies were determined for it, PID control methods in combination with fuzzy logic were used. Results showed a better performance with fuzzy logic than with classic PID

Sistemas de automação e supervisão do laboratório de avaliação dos processos de medição de vazão e BSW

During a petroleum well production process, It is common the slmultaneous oil and water production, in proportion that can vary from 0% up to values close to 100% of water. Moreover, the production flows can vary a lot, depending on the charaeteristies of eaeh reservoir. Thus being, the meters used in field for the flow and BSW (water in the oil) measurement must work well in wide bands of operation. For the evaluation of the operation of these meters, in the different operation conditions, a Laboratory will be built in UFRN, that has for objective to evaluate in an automatic way the processes of flow and BSW petroleum measurement, considering different operation conditions. The good acting of these meters is fundamental for the accuracy of the measures of the volumes of production liquid and rude of petroleum. For the measurement of this production, the petroleum companies use meters that should indicate the values with tha largast possible accuracy and to respect a series of conditions and minimum requirements, estabelished by the united Entrance ANP/INMETRO 19106/2000. The laboratory of Evafuation of the Processes of Measurement of Flow and BSW to be built will possess an oil tank basically, a tank of water, besides a mixer, a tank auditor, a tank for separation and a tank of residues for discard of fluids, fundamental for the evaluation of the flow metars and BSW.

The considered work presents the procedure for evaluation of the uncertainty related to the calibration of flow measurers and to BS&W. It is about a new method of measurement purposed by the conceptual project of the laboratory LAMP, at Universidade Federal do Rio Grande do Norte, that intends to determine the conventional true value of the BS&W from the total height of the liquid column in the auditor tank, hydrostatic pressure exerted by the liquid column, local gravity, specific mass of the water and the specific mass of the oil, and, to determine the flow, from total height of liquid column and transfer time. The calibration uses a automatized system of monitoration and data acquisition of some necessary largnesses to determine of flow and BS&W, allowing a better trustworthiness of through measurements

Desenvolvimento de protótipo de coletor automático destinado à coleta de amostras de água em corpos aquáticos para análise em laboratório

The aim of this approach is to describe the design and construction of a low-cost automated water sampler prototype. In recent years, there is an increasing need on the use of automated equipments for hydro climatic variables to be use in urban and rural environments. Such devices are always used to provide measured information which is of crucial importance on the development of water resources strategies at watershed scale. Actually, many research and water public institutions have been using these kinds of equipments. In most of the cases, automated equipments are expensive and need to be imported, generating a situation of technologic dependency. The prototype is based on an electronic system which controls a peristaltic pump functioning, five solenoid valves and an ultrasonic sensor connected to a datalloger. An interface with the user allows communication with a PC, when the equipment functioning parameters can be provided. The equipment has a hydraulic module composed by a 12V peristaltic pump connected to a distribution circuit composed by five solenoid valves, one of them being used to clean the circuit before each sampling procedure. Samples are collected by four 1.95 polyethylene bottles. The sampler body was made of acrylic material, with a cylindrical shape, and dimensions 0.72 m and 0.38 m height and diameter, respectively. The weight of the equipment without samples is approximately 15 kg, which infers to its portability. The prototype development total cost budget was approximately US$ 1,560.00. Laboratory tests aimed to evaluate the equipment performance and functioning demonstrated satisfactory results

Distribuição diária do comportamento da mosca da fruta Anastrepha zenildae Zucchi, (Diptera: Tephritidae) em laboratório.

The knowledge of Anastrepha zenildae behavioral aspects combined with the biology of Tephritidae may contribute to monitoring and control programs of this fruit fly that is considered as economically important to the Rio Grande do Norte state. In order to characterize the daily activity profile of this species, we studied the behaviors of resting, locomotion, feeding, cleaning, courtship, copulation and oviposition of animals submitted to an artificial 12:12h light-dark cycle (750:1lux) with controlled temperature (26±2 °C). The observations were made with groups of 16 males and 16 females during 3 consecutive days each generation from parental to F5. Resting, locomotion, feeding and cleaning data were recorded as frequency and time of occurrence by scanning technique in 15 minutes windows per hour, with a record each minute. Courtship, copulation and oviposition were recorded as frequency, time of occurrence and duration by al occurrences technique. Resting was the most frequent behavior with males resting more than females. Locomotion was more evident in the first half of the ligh phase with higher values in females. Cleaning and feeding behaviors were more frequent in the second half of the light phase for both sexes with females eating more frequently than males. During the courtship, males were grouped in lek formations showing wings vibration and pheromone liberation. Courtship occurred more frequently 4 to 7 h after lights on (81,9%) with copulations being more frequent 6 h after lights on with a mean duration of 58,1±40,4 min. Copulation attempts were observed in males inside and outside the lek with aggressive behavior being observed only between males in the lek. Oviposition behavior was similar to that described for other species of the genus with a peak of this activity 2-3 h after the lights on, mean duration of 43, 7±34, 8 sec and 2 to 5 eggs by event. According to the results, sexual behavior of A. zenildae is temporally different of other sympatric species of the genus, being favorable to the reproductive isolation as well as the use of resources as oviposition substrate.
