1. Estudo de modelos e condições iniciais da geração a priori de detritos espaciais e sua propagação orbital / Study of models and initial conditions of a priori generation of space debris and their orbital propagation
Currently, it is estimated that there are hundreds of thousands of space debris, of various sizes, around the Earth. The space debris, also known as orbital debris, can remain in orbit with other bodies for a long time; and can cause risks of collision, including with space vehicles still in operation. In addition, there are risks of potential accidents by r

2. WEB-PerformCharts: gerando casos de testes via web a partir de especificações em statecharts / WEB-PerformCharts: a web-based test case generator from statecharts modeling
Distributed development of software is an increasing approach where teams spread over a country or even over the world can work together in order to develop the product. Web appears as a valuable resource enabling the cooperative development of software by professionals geographically distant from each other. This dissertation proposes a web-based tool, WEBP

3. GENERATION AND TRANSMISSION SYSTEM RELIABILITY CONSIDERING STATIC AND DYNAMIC ASPECTS / CONFIABILIDADE DE SISTEMAS DE GERAÇÃO E TRANSMISSÃO CONSIDERANDO ASPECTOS ESTÁTICOS E DINÂMICOS
Traditionally, bulk power reliability evaluations have concentrated on the analysis of system adequacy, the ability of the generating and the transmission systems to supplhy all loadas within performance requirements. This work presents a new methodology that extends the scope of reliability evaluations to include probabilistic assessment of system security,

4. DETERMINAÇÃO DO VALOR DA CONFIABILIDADE EM SISTEMAS COMPOSTOS DE GERAÇÃO E TRANSMISSÃO / EVALUATION OF RELIABILITY WORTH IN COMPOSITE GENERATION AND TRANSMISSION SYSTEMS
This work presents a new methodology to evaluate reliability índices in composite generation and transmission systems. Through this new approach is possible to achieve an accurate estimate of the reliability worth of power systems. The modeling flexibility and simulation efficiency are basic features of the proposed approach. Moreover, it is introduced a ne

6. Detection of hepatitis C virus sequences in sera with controversial serology by nested polymerase chain reaction.
The specificity of first-generation enzyme-linked immunosorbent assays (ELIAs) for antibody detection in individuals with hepatitis C virus (HCV) infection has been questioned in some pathological situations. We observed a surprisingly high prevalence of anti-HCV antibodies in alcoholic patients, and thus, false-positive reactions in anti-HCV tests were stro

7. Relation between cognitive dysfunction and pseudobulbar palsy in amyotrophic lateral sclerosis.
OBJECTIVES: To examine the relation between cognitive dysfunction and pseudobulbar features in patients with amyotrophic lateral sclerosis (ALS). METHODS: The performance of two patient groups, ALS with pseudobulbar palsy (n = 24) and ALS without pseudobulbar palsy (n = 28), was compared with 28 healthy age matched controls on an extensive neuropsychological

8. Isolation of dominant negative mutants and inhibitory antisense RNA sequences by expression selection of random DNA fragments.
Selective inhibition of specific genes can be accomplished using genetic suppressor elements (GSEs) that encode antisense RNA, dominant negative mutant proteins, or other regulatory products. GSEs may correspond to partial sequences of target genes, usually identified by trial and error. We have used bacteriophage lambda as a model system to test a concept t

9. High-frequency changes in transcriptional activity in polyomavirus-transformed cell lines.
We applied the Luria and Delbruck fluctuation test to analyze high-frequency changes in the phenotype of rat cells transformed by a plasmid carrying the polyomavirus middle T (pmt) gene. All of the transformed cell lines analyzed were capable of switching to the normal state with rates ranging from 10(-3) to 10(-2) per cell per generation. Analysis of both m

10. Simple and efficient generation in vitro of nested deletions and inversions: Tn5 intramolecular transposition.
We have exploited the intramolecular transposition preference of the Tn 5 in vitro transposition system to test its effectiveness as a tool for generation of nested families of deletions and inversions. A synthetic transposon was constructed containing an ori, an ampicillin resistance (Ampr) gene, a multi-cloning site (MCS) and two hyperactive end sequences.

11. Rate constancy of globin gene evolution in placental mammals.
The molecular clock hypothesis is investigated by comparison of the rates of nucleotide substitution in globin genes of mice, cows and goats, humans, and rabbits, using the relative rate test. These comparisons are based on a branching order of genes and species established by cladistic analysis of nucleotide sequences. The species branching order is shown t

12. Intracellular inhibition of hepatitis C virus (HCV) internal ribosomal entry site (IRES)-dependent translation by peptide nucleic acids (PNAs) and locked nucleic acids (LNAs)
Hepatitis C virus (HCV) is the major etiological agent of non-A, non-B hepatitis. Current therapies are not effective in all patients and can result in the generation of resistant mutants, leading to a need for new therapeutic options. HCV has an RNA genome that contains a well-defined and highly conserved secondary structure within the 5′-untranslated reg
