1. Interaction Analysis of Non-aligned Cracks Using Extended Finite Element Method
Abstract Multiple flaws are frequently occurred in actual components, such as pressure vessels and power plants. These flaws will in some circumstances lead to more severe effects than single flaw alone. Assessment of the interaction behavior is based on the evaluation of alignment and combination of these multiple flaws. In the current standards, multiple c

2. Effect of contrast and gaps between Vernier stimulus elements on sweep visual evoked potential measurements of human cortical Vernier responses
The present paper focuses on a classic hyperacuity, Vernier acuity-the ability to discriminate breaks in the collinearity of lines or edges on the order of only arcseconds of visual angle. We measured steady-state sweep visual evoked potentials (sVEPs) in response to 6 Hz periodic breaks in collinearity (Vernier offsets) in horizontal squarewave gratings. Ve

3. Alinhamentos e comparação de sequências / Alignment and comparison of sequences
A comparação de sequências finitas é uma ferramenta que é utilizada para a solução de problemas em várias áreas. Comparamos sequências inferindo quais são as operações de edição de substituição, inserção e remoção de símbolos que transformam uma sequência em uma outra. As matrizes de pontuação são estruturas largamente utilizadas e

4. Navegação terrestre usando unidade de medição inercial de baixo desempenho e fusão sensorial com filtro de Kalman adaptativo suavizado. / Terrestrial navigation using low-grade inertial measurement unit and sensor fusion with smoothed adaptive Kalman filter.
This work presents the development of the mathematical models and the algorithms of a sensor fusion system for terrestrial navigation using a low-grade inertial measurement unit (IMU) and the Extended Kalman Filter. The models were developed on the basis of the strapdown inertial navigation systems (SINS). Low-grade designates an IMU that is not able to perf

5. Cloning, sequence analysis, and expression of cDNA coding for the major house dust mite allergen, Der f 1, in Escherichia coli
Our objective was to clone, express and characterize adult Dermatophagoides farinae group 1 (Der f 1) allergens to further produce recombinant allergens for future clinical applications in order to eliminate side reactions from crude extracts of mites. Based on GenBank data, we designed primers and amplified the cDNA fragment coding for Der f 1 by nested-PCR

6. Estratégia e competências : um estudo na indústria de fios da Cocamar Cooperativa Agroindustrial
Until the 80´s, the studies about strategies were focused in the external variable to the company. During the 80´s and 90´s, posture and cultural factors got space in the studies about strategy, valorizing the company´s internal abilities and technologies. The competencies started then to be observed in the studies about strategies, but with different pa

7. Widespread protein sequence similarities: origins of Escherichia coli genes.
To learn more about the evolutionary origins of Escherichia coli genes, we surveyed systematically for extended sequence similarities among the 1,264 amino acid sequences encoded by chromosomal genes of E. coli K-12 in SwissProt release 26 by using the FASTA program and imposing the following criteria: (i) alignment of segments at least 100 amino acids long

8. Homology-extended sequence alignment
We present a profile–profile multiple alignment strategy that uses database searching to collect homologues for each sequence in a given set, in order to enrich their available evolutionary information for the alignment. For each of the alignment sequences, the putative homologous sequences that score above a pre-defined threshold are incorporated into a p

9. Automatic generation of primary sequence patterns from sets of related protein sequences.
We have developed a computer algorithm that can extract the pattern of conserved primary sequence elements common to all members of a homologous protein family. The method involves clustering the pairwise similarity scores among a set of related sequences to generate a binary dendrogram (tree). The tree is then reduced in a stepwise manner by progressively r

10. Introns of the chicken ovalbumin gene promote nucleosome alignment in vitro.
A defined in vitro chromatin assembly system was used to examine the nucleosome alignment induced by histone H5 throughout a 12 kilobase pair chicken genomic DNA fragment containing the ovalbumin gene. In contrast with total fragmented chicken DNA and several anonymous cloned fragments, much of the gene permitted histone H5 to space nucleosomes at physiologi

11. Identification and analysis of ‘extended –10’ promoters in Escherichia coli
We have compiled and aligned the DNA sequences of 554 promoter regions from Escherichia coli and analysed the alignment for sequence similarities. We have focused on the similarities and differences between promoters that either do or do not contain an extended –10 element. The distribution of –10 and –35 hexamer element sequences, the range of spacer

12. Statistical significance of protein structure prediction by threading
In this study, we estimate the statistical significance of structure prediction by threading. We introduce a single parameter ɛ that serves as a universal measure determining the probability that the best alignment is indeed a native-like analog. Parameter ɛ takes into account both length and composition of the query sequence and the number of decoys in th
