Análise de ambiguidade em métodos de campo potenciais através de análise fatorial, Q-Modal

Este trabalho apresenta uma metodologia para o estudo da ambiguidade na interpretação de dados geofísicos. Várias soluções alternativas, representativas da região de maior ambiguidade no espaço de parâmetros são obtidas, sendo posteriormente grupadas e ordenadas pela análise fatorial modo Q. Esta metodologia foi aplicada a dados sintéticos de campo potencial simulando-se causas de ambiguidade como discretização e truncamento da anomalia e a presença de ruídos aleatório e geológico. Um único prisma foi usado como modelo interpretativo, sendo a espessura a principal causa de ambiguidade tanto na gravimetria como na magnetometria. Segue-se a profundidade do topo sempre associada à espessura, quando o sinal da anomalia é alto. Quando a anomalia tem sinal baixo, a largura torna-se o segundo parâmetro mais importante, também associada à espessura. Ao contrário da presença de interferências geológicas, a presença de ruído aleatório nos campos, não é fator importante na ambiguidade. A aplicação da metodologia a dados reais ilustra o papel desta análise na caracterização de soluções alternativas e a importância da informação a priori na caracterização das causas de ambiguidade. A metodologia apresentada pode ser empregada em diversos estágios de um programa de prospecção fornecendo em cada estágio uma análise dos principais fatores causadores da ambiguidade, que poderá ser util no planejamento dos estágios seguintes. Comparada a outros métodos de análise de ambiguidade, como por exemplo regiões de confiança, a metodologia estudada destaca-se por não precisar satisfazer premissas estatísticas sobre a distribuição dos erros.

Cyclic codes through B[X;(a/b)Z_0, with (a/b) in Q^{+} and b=a+1, and Encoding

Let B[X; S] be a monoid ring with any fixed finite unitary commutative ring B and is the monoid S such that b = a + 1, where a is any positive integer. In this paper we constructed cyclic codes, BCH codes, alternant codes, Goppa codes, Srivastava codes through monoid ring . For a = 1, almost all the results contained in [16] stands as a very particular case of this study.

Lattices from subfields of Q (xi n)

In this paper we present a method for evaluating the center density of algebraic lattices from subfields of Q(xi n), where n is a positive integer. This method allows to reproduce rotated versions of dense lattices in some dimensions. Constellations on algebraic lattices with high packing density have been proposed for use in communications in Gaussian channels and also in Rayleigh fading channels in case they have high diversity.

Q-angle static or dynamic measurements, which is the best choice for patellofemoral pain?

The elevated Q-angle seems to be one of the most suggested factors contributing to patellofemoral pain. Females with patellofemoral pain are often evaluated through static clinical tests in clinical practice. However, the adaptations seem to appear more frequently in dynamic conditions. Performing static vs. dynamic evaluations of widely used measures would add to the knowledge in this area. Therefore, the aim of this study was to determine the reliability and discriminatory capability of three Q-angle measurements: a static clinical test, peak dynamic knee valgus during stair ascent and a static measurement using a three-dimensional system. Twenty-nine females with patellofemoral pain and twenty-five pain-free females underwent clinical Q-angle measurement and static and dynamic knee valgus measurements during stair ascent, using a three-dimensional system. All measurements were obtained and comparisons between groups, reliability and discriminatory capability were calculated. Peak dynamic knee valgus was found to be greater in the patellofemoral pain group. On the other hand, no significant effects were found for static knee valgus or clinical Q-angle measurements between groups. The dynamic variable demonstrated the best discriminatory capability. Low values of reliability were found for clinical Q-angle, in contrast to the high values found for the three-dimensional system measurements. Based on our findings, avoiding or correcting dynamic knee valgus during stair ascent may be an important component of rehabilitation programs in females with patellofemoral pain who demonstrate excessive dynamic knee valgus. Q-angle static measurements were not different between groups and presented poor values of discriminatory capability.

Evaluation of the use of probiotic acid lactic bacteria in the development of chicken hambúrguer

The objective of this study was to investigate the effect of fermentation with Lactobacillus acidophilus CRL 1014 on the physicochemical, microbiological and sensory characteristics of a hamburger product like processed with chicken meat and okara flour, with reduction of curing salts. A mixture of ingredients containing 90% chicken meat and 10% okara flour was subjected to the following treatments: F1: fermented with Lactobacillus acidophilus; F2:75 mg nitrite/kg and fermented with Lactobacillus acidophilus; F3: 150 mg nitrite/kg and unfermented. The quality of the “hamburgers” was assessed by physical and chemical analysis (pH, cooking yield and shrinkage), chemical composition, microbiological tests (Salmonella spp., count of sulphite-reducing clostridia, staphylococos coagulase-positive, total coliforms and Escherichia coli) and sensory analysis (sensory acceptance and purchase intent). During the first six days of fermentation, there was a decrease in pH from approximately 6.33 to 5.10. All the samples showed the same chemical composition (p < 0.05). The fermentation process was observed to inhibit the multiplication of microorganisms of several groups: coagulasepositive staphylococci, sulphite-reducing clostridia, Salmonella spp. and E. coli. The different “hamburgers” formulations showed high scores for all the sensory attributes evaluated, without differing from each other (p < 0.05). The results showed that the use of L. acidophilus CRL 1014 enabled the production of a safe product, with good physicochemical and sensory characteristics, in the absence of curing salts.

Safe by a Mile

Charlie Metro's career runs the gamut of the specialties found in baseball-player, coach, manager, scout, inventor. Metro has lived baseball at every level from the Great Depression to today's multimillion dollar contracts. One of a kind, Metro's life mirrors the astounding changes in the game as well as in the nation. Metro's tale is full of heart and a wealth of anecdotes, the result of a fascinating life and a true love of the game. Charlie Metro was born Charles Moreskonich in Nanty-Glo, Pennsylvania, in 1919. He played in the major leagues from 1943 to 1945 with the Detroit Tigers and the Philadelphia Athletics. He managed for parts of two seasons, with the 1962 Cubs and the 1970 Kansas City Royals. He also coached the 1965 Chicago White Sox and the 1982 Oakland Athletics. Although he had far longer service in the minor leagues, he will probably be best remembered as one of the great scouts and teachers in baseball history.
