1. Investigations on DNA damage and frequency of micronuclei in occupational exposure to electromagnetic fields (EMFs) emitted from video display terminals (VDTs)
The potential effect of electromagnetic fields (EMFs) emitted from video display terminals (VDTs) to elicit biological response is a major concern for the public. The software professionals are subjected to cumulative EMFs in their occupational environments. This study was undertaken to evaluate DNA damage and incidences of micronuclei in such professionals.

2. Simulador eletromagnético em um ambiente de grades computacionais / Eletromagnetic simulator in a grid computing environment
The aim of this work is to develop the Pre and Post-Processing stages from an electromagnetic simulation suite, called SSAR-BR, and also a grid computational environment, which permits the execution of large electromagnetic problems. The processing stage, based in the Finite Difference Time Domain (FDTD) method, has been already developed as part of a doctor

3. Árvores de Steiner: Teoria, Geração Numérica e Aplicações / Steiner trees: Theory, Numerical Generation and Applications
Given a set of points in the plane, which we call terminals, one proves that they are always connected by a minimal graph called Steiner tree. The terminals may represent main connection route points, circuit elements or network computer servers. That is, the problem is to optimize traffic among the terminals whenever this is represented by a tree of shortes

5. INTERACTION BETWEEN LOW-RIPPLE SWITCHED CONVERTERS AND FUEL CEL LS / INTERAÇÃO ENTRE CONVERSORES CHAVEADOS COM BAIXA ONDULAÇÃO E CÉLULAS DE COMBUSTÍVEL
This dissertation discusses the interaction between fuel cells and the DC-DC converter just connected across its terminals. For that, it presents a modified algorithm to represent the dynamic behavior of fuel cell stacks as much the current ripple effects from power converters on such cells. PEM type fuel cells (Proton Exchange Membrane) are studied to get a

8. Projeto de terminais intermodais de carga utilizando os conceitos CADD e simulação
The process of designing freight intermodal terminals is growing in magnitude in the Brazilian cenary since the privatization of the former state railways. Given the modal competition at the present time, it is imperative to achieve a high level of efficiency in both physical and operational design of terminals. The aim of this work is to present a design me

9. Computers as learning resources in the health sciences: impact and issues.
Starting with two computer terminals in 1972, the Health Sciences Learning Resources Center of the University of Minnesota Bio-Medical Library expanded its instructional facilities to ten terminals and thirty-five microcomputers by 1985. Computer use accounted for 28% of total center circulation. The impact of these resources on health sciences curricula is

12. Cost considerations in automating the library.
The purchase price of a computer and its software is but a part of the cost of any automated system. There are many additional costs, including one-time costs of terminals, printers, multiplexors, microcomputers, consultants, workstations and retrospective conversion, and ongoing costs of maintenance and maintenance contracts for the equipment and software,
