A multimedia environment for supporting the teaching of robotics systems

This paper aims at describing an educational system for teaching and learning robotic systems. Multimedia resources were used to construct a virtual laboratory where users are able to use functionalities of a virtual robotic arm, by moving and clicking the mouse without caring about the detailed internal robot operation. Moreover through the multimedia system the user can interact with a real robot arm. The engineering students are the target public of the developed system. With its contents and interactive capabilities, it has been used as a support to the traditional face-to-face classes on the subject of robotics.. In the paper it is first introduced the metaphor of Virtual Laboratory used in the system. Next, it is described the Graphical and Multimedia Environment approach: an interactive graphic user interface with a 3D environment for simulation. Design and implementation issues of the real-time interactive multimedia learning system, which supports the W3C SMIL standard for presenting the real-time multimedia teaching material, are described. Finally, some preliminary conclusions and possible future works from this research are presented.

Teaching robotics systems in a multimedia environment

This paper describes the development of a multimedia educational system to teach and learn robotic systems. Multimedia resources have been used to build a virtual laboratory where users are able to utilize functions of a robotic arm, by moving and clicking the mouse without worrying about the detailed robot internal operation. The multimedia system is integrated with a real robotic arm, which was also developed at the university. Through robotic topic presentations and interactive capabilities provided by this system and its tools, students can devote themselves on the learning process just as they do in the traditional face-to-face classes. and the target public of this system are the engineering students themselves.

O laboratório de ensino de ciências como espaço privilegiado para o planejamento de regência nos estágios supervisionados

El objetivo de este estudio fue investigar la posible contribución del desarrollo la Planificación de la Regencia en el Laboratorio de Enseñanza de la Ciencia para el curso de enseñanza en Biología. Con este fin, se aplicó un cuestionario abierto a 16 estudiantes de la Licenciatura en Ciencias Biológicas de la UnB, la identificación de la percepción inicial de la actividad en el inicio del curso, los cambios en estas percepciones a través del tiempo y sus opiniones sobre el potencial y las limitaciones de utilizar este espacio para la preparación de las clases. Por experiencia, los estudiantes reportaron la percepción del laboratorio como un espacio de colaboración que proporciona mejoras en la práctica, y facilitar el acceso a diversos materiales para las clases de enriquecimiento. Las actividades del Laboratorio de Enseñanza permitió el escenario se reunieron los aspectos fundamentales de la formación docente constituye un espacio de reflexión sobre la construcción y el fortalecimiento de la identidad docente

Virtual instrumentation: A practical approach to control and supervision process

This work describes a control and supervision application takes into account the virtual instrumentation advantages to control and supervision industrial manufacturing stations belonging to the modular production system MPS® by Festo. These stations integrate sensors, actuators, conveyor belt and other industrial elements. The focus in this approach was to replace the use of programmable logic controllers by a computer equipped with a software application based on Labview and, together, performs the functions of traditional instruments and PLCs. The manufacturing stations had their processes modeled and simulated in Petri nets. After the models were implemented in Labview environment. Tests and previous similar works in MPS® installed in Automation Laboratory, at UNESP Sorocaba campus, showed the materials and methods used in this work allow the successful use of virtual instrumentation. The results indicate the technology as an advantageous approach for the automation of industrial processes, with gains in flexibility and reduction in project cost. © 2011 IEEE.

Clinical and laboratory evaluation of horses after intraperitoneal injection of lipopolysaccharide (LPS)

Horses are very sensitive to Gram-negative bacterial lipopolysaccharides (LPS) which, when introduced into the blood stream, induce several responses mediated by endogenous pro-inflammatory mediators originating from bacteriolysis or granulocyte disintegration. Intraperitoneal LPS injection was used to mimic the proposed route of endotoxin travel in clinical cases. The clinical signs and laboratory findings demonstrated a dose- dependent effect and were more consistently observed with 500 ng/kg of LPS. We conclude that intraperitoneal injection of LPS produces the same endotoxic status as obtained by systemic injection of LPS, even during the initial phase.

Neotenic formation in laboratory colonies of the termite Coptotermes gestroi after orphaning

The termite Coptotermes gestroi (Wasmann 1896) ( Rhinotermitidae: Coptotermitinae) is an exotic species in Brazil and information concerning its reproductive developmental biology is scarce. We induced the formation of neotenics in laboratory colonies through orphaning experiments. Orphaning experiments were conducted in three-year old colonies of C. gestroi kept under laboratory conditions. After three months, eight nymphoid neotenics were observed in one colony after queen removal. Histological analysis showed that these neotenics were non-functional. The results suggest that these individuals may have arisen from the first nymphal instar (N1) or from an early N1 instar after one or two larval moults. Neotenics also were recorded on two incipient colonies of C. gestroi that lost the queen naturally.

BACTERIAL LEACHING OF URANIUM ORE FROM FIGUEIRA-PR, BRAZIL, AT LABORATORY AND PILOT-SCALE

A bacterial leaching program was carried out in order to evaluate the potential of applying this process to leach uranium from the ore of Figueira-PR, Brazil. The experiments were carried out in shake flasks, column percolation (laboratory and semipilot scale) and in heap leaching. In shake flasks and in column percolation experiments at laboratory scale, bacterial activity on the ore was confirmed: approximately 60% of uranium was leached, against around 30% in sterilized controls. Column percolation experiments at semipilot scale and heap leaching (850 tons of ore) showed uranium extractions of approximately 50%. In both experiments, a complementary sulfuric acid attack, after the bacterial leaching phase, was necessary to reach this level of uranium extraction.

ZOEAL MORPHOLOGY OF PACHYGRAPSUS-GRACILIS (SAUSSURE, 1858) (DECAPODA, GRAPSIDAE) REARED IN THE LABORATORY

The larval development of Pachygrapsus gracilis was studied in the laboratory under conditions of 25-degrees-C temperature and 20, 24, 28, 32 and 34 parts per thousand salinity. The objective of the study was to characterize the plankton phase of life of this species.

Training courses for teachers through the distance learning: practice reports used virtual environment TELEDUC

This paper describes the experiences of long-distance courses, it focused on the continuing education of basic education teachers in all Brazilian territory. Such courses were offered by CECEMCA (Center for Continuing Education in Mathematics Education, Science and Environment), linked to the Universidade Estadual Paulista Julio de Mesquita Filho - Campus de Rio Claro during 15/01/2009 to 30/11/2009. The subjects report to the theme of Education, Geography and Environment, it was organized in four courses: "Introduction to Cartography," Environment and climate change - thinking a new paradigm of sustainable green planet "," Remote Sensing in environmental studies Environment "and" Methodological Alternatives for Inclusive Classroom: Experimenting with visual and hearing impairments". So, we show here, the feasibility and importance of distance learning tools for education, specifically teacher training, based on the results obtained in these courses.

Occurrence of different gynandromorphs and ergatandromorphs in laboratory colonies of the urban ant, Monomorium floricola

Colonies of Monomorium floricola (Jerdon) in laboratory conditions showed gynandromorphic and ergatandromorphic specimens, the former with nine different combinations of male and female tissues and the latter with 6 different combinations. Their development from egg to adult was around 74.6 days for gynandromorphs, and 87.5 days for ergantandromorphs.
