Animais de laboratório: O camundongo

The animal experimentation in the scientific research has contributed excessively for the development of science and technology, promoting to long of the years the discovery of prophylactic measures and treatments for diseases that attack the humans. Animals of some species have been used in the last times, being the mouse the more intensely used and more deeply known scientifically. The objective of this work was to carry through a bibliographical survey including data of our research group, about the use of mice in the animal experimentation, approaching its general biology, reproduction physiology, creation systems, genetics, habitation, feeding, handling, pain and euthanasia, techniques of risk developed in the experimentation, blood collection, pharmacological and toxicological experiments. Although current trends praise the use of alternative methods (in vitro studies, cells cultures, etc.), the animal models, as the mouse, present as main advantage the supply of information on the organism as a whole, fact that is not obtained with other methods, what still it makes possible its utilization in scientific research.

A mechanical analogous model for the power system with Automatic Voltage Regulator

This paper deals with the subject-matter of teaching immaterial issues like power system dynamics where the phenomena and events are not sense-perceptible. The dynamics of the power system are recognized as analogous to the dynamics of a simple mechanical pendulum taken into account the well-known classical model for the synchronous machine. It is shown that even for more sophisticated models including flux decay and Automatic Voltage Regulator the mechanical device can be taken as an analogous, since provided some considerations about variation and control of the pendulum length using certain control laws. The resulting mathematical model represents a mechanical system that can be built for use in laboratory teaching of power system dynamics. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.

Enfermeiros e a família do portador de transtorno mental.

This qualitative study aimed at investigating how mental health nurses acquired knowledge about the theme family during their academic training, how they see families in their daily practice, and how should professional training be considering the presence of the family in the care setting. Data were collected using semistructured questionnaires. Six nurses were interviewed. Data analysis allowed the establishment of three theme categories: Academic and professional training absence of the family theme; the nurses' perception of the family with a mentally ill member; and a new vision of the family the role of teaching. During undergraduate education, nurses acquired little knowledge about the theme family; in the institutional routine, they praise the family as a participant of care; and indicate that the need for knowledge about families is based on the interdisciplinary character of education.

Power Oscillation index - A tool for investigation into unbalance phenomena in the distribution Networks

Unbalance and harmonics are two major distortions in the three-phase distribution systems. In this paper an investigation into unbalance phenomena in the distribution networks using instantaneous space vector theory, is presented. Power oscillation index (POI) and effective power factor (PFe) are calculated in the network nodes for several unbalance loading conditions. For system analysis a general power flow algorithm for three-phase four-wire radial distribution networks, based on backward-forward technique, is applied. Results obtained from several case studies using medium and low voltage test feeder with unbalanced load, are presented and discussed. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.

Entransy and its utilization in problems of thermodynamics and heat transfer

The concept of entransy was recently proposed in terms of the analogy to the electric energy stored in a capacitor. The entransy of a system describes its heat transfer ability, as the exergy of a system quantifies its work production potential. Hence, the concept of entransy can be useful in problems where the heat transfer is the main objective, as for example, in systems collecting solar energy. This concept is quite recent and there are only a few works related to this topic. It is expected, however, that this approach will soon be used more often in the analysis of problems in thermodynamics and heat transfer. The objective of this work is to present a review of the concept of entransy in a systematic way, beginning with its definition, balance equations and a few examples of simple applications. It is hoped that this concept of entransy becomes a useful tool in the analysis and design of more efficient thermal systems. © 2012 Praise Worthy Prize S.r.l.- All rights reserved.

Mobile Robot navigation modelling, control and applications

This work presents and discusses the main topics involved on the design of a mobile robot system and focus on the control and navigation systems for autonomous mobile robots. Introduces the main aspects of the Robot design, which is a holistic vision about all the steps of the development process of an autonomous mobile robot; discusses the problems addressed to the conceptualization of the mobile robot physical structure and its relation to the world. Presents the dynamic and control analysis for navigation robots with kinematic and dynamic model and, for final, presents applications for a robotic platform of Automation, Simulation, Control and Supervision of Mobile Robots Navigation, with studies of dynamic and kinematic modelling, control algorithms, mechanisms for mapping and localization, trajectory planning and the platform simulator. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

O Brasil “civilizado” e o Japão “bizarro” na revista Kosmos: imagens contrastantes

Este artigo discute as relações entre idéias de progresso da capital federal brasileira no começo do século XX e a imagem bizarra do Japão e dos japoneses veiculadas dentro de um dos periódicos brasileiros mais requintados da época: a revista Kosmos. Em contraposição aos artigos de louvor às melhorias urbanas promovidas pelo governo carioca; as crônicas de viagem de países “exóticos” como o Extremo Oriente tiveram um papel fundamental na promoção da auto-estima da elite brasileira que se pretendia civilizada, moderna e branca.
