Tilings induced by a class of cubic Rauzy fractals

We study aperiodic and periodic tilings induced by the Rauzy fractal and its subtiles associated with beta-substitutions related to the polynomial x3-ax2-bx-1 for a≥b≥1. In particular, we compute the corresponding boundary graphs, describing the adjacencies in the tilings. These graphs are a valuable tool for more advanced studies of the topological properties of the Rauzy fractals. As an example, we show that the Rauzy fractals are not homeomorphic to a closed disc as soon as a≤2b-4. The methods presented in this paper may be used to obtain similar results for other classes of substitutions.© 2012 Elsevier B.V. All rights reserved.

Comparison between the six-minute walk test and the six-minute step test in post stroke patients

Background: The Stroke remains one of the major chronic diseases worldwide, and is considered a major cause of disability, which results not only in persistent neurological deficits, but also in the high physical deconditioning, nevertheless there are not many forms of assessing functional capacity in this population. We aimed to investigate the feasibility of the Six Minute Walk Teste and the Six-Minute Step Test (6MST) in post-stroke patients and compare the behavior of physiological variables during the 6MST and the Six-Minute Walk Test (6MWT), by correlating the functional performance obtained in both tests. Method. The 6MWT was carried out according to the American Thoracic Society (ATS) and the 6MST was performed in six minutes in order to compare it to the 6MWT in a 20 cm step. Was included post-stroke individuals able to walk without aid. All of them did the 6MWT and the 6MST. Results: 12 patients participated in the study. There was no statistical difference in the parameters analyzed when tests were compared. There was poor correlation between the functional performance in both tests. Conclusion: The 6MWT and the 6MST is feasible for post-stroke patients and physiological responses are equal during the performance of both tests. However, there was no correlation with respect to functional performance, which was assessed by the distance walked in the 6MWT and by the number of steps climbed in the 6MST. © 2013 da Silva et al.; licensee BioMed Central Ltd.

Efeito do uso do hábitat sobre a comunidade de Gerromorpha (Heteroptera) em uma área de transição Amazônia-cerrado, Mato Grosso, Brasil

Os Heteroptera aquáticos e semi-aquáticos consistem em três infra-ordens monofiléticas, os Gerromorpha, Nepomorpha e Leptopodomorpha. No Brasil, existe um número bastante reduzido de literatura sobre este grupo, onde o estado de Minas Gerais concentra o maior número de estudos. Este trabalho objetivou determinar o efeito da intensidade de uso da terra sobre a comunidade de heterópteros aquáticos, infra-ordem Gerromorpha. A área de estudo está localizada na Fazenda Tanguro, estado do Mato Grosso, em uma faixa de transição entre os biomas Amazônia e Cerrado. Foram realizadas quatro expedições nos meses de maio e julho, nos anos de 2006 e 2007. As coletas foram realizadas ao longo de seis riachos de primeira ordem localizados em três áreas diferentes: campo de soja, pastagem e mata contínua. Foram encontrados 5 famílias, 19 gêneros, 36 espécies e 13 morfoespécies de Gerromorpha. As curvas médias de acumulação de espécies para cada uma das três áreas de estudo não atingiram a assíntota ao final da adição de amostras, mas demonstraram uma clara tendência a estabilização, sugerindo que um aumento do esforço amostral aproximaria o número de espécies observadas da realidade do local de estudo. Embora a cobertura vegetal tenha sido significativamente diferente entre as três áreas estudadas (ANOVA, F2,45= 23,72; P < 0,001), o tipo de hábitat não influenciou no número de espécies de Gerromorpha (ANOVA F3,44= 0,77; P = 0,52). Sete espécies apresentaram diferenças significativas entre os hábitats. Os dois eixos do MDS baseados na composição das espécies não separaram as espécies quanto ao tipo de hábitat. Para a matriz de abundância, o eixo 1 (MANOVA; F2,45 = 16,27; P < 0,001) e o eixo 2 (MANOVA; F2,45 = 6,31; P = 0,004) diferenciaram as espécies que ocorreram na área de mata contínua. Um total de 57,14% das espécies coletadas é compartilhado pelas três áreas de estudo. A sensível redução no número de indivíduos registrados da área mais conservada (mata contínua) para as áreas degradadas (plantio de soja e pastagem, respectivamente) possivelmente está relacionada à perda de cobertura vegetal observada nas áreas degradadas. As espécies Brachymetra lata, Brachymetra sp 1, Cylindrostethus palmaris, Tachygerris celocis, Rhagovelia paulana, e Rhagovelia whitei podem ser consideradas espécies indicadoras de áreas florestadas; e Neogerris lubricus pode ser indicadora de ambientes sem cobertura vegetal.

Crescimento e nutrição mineral de Sida rhombifolia

This experiment was carried out to analyze dry mass production and distribution, and the content and accumulation of macronutrients in arrowleaf sida (Sida rhombifolia) plants cultivated under mineral nutrition standard conditions. Plants grew in seven liter pots filled with sand substrate and daily irrigated with nutrient solution, under greenhouse conditions. Treatments consisted of times of evaluation (21, 35, 49, 63, 77, 91, 105, 119, and 133 days after emergence - DAE) and were arranged in a completely randomized design with four replicates. Arrowleaf sida plants showed small accumulation of dry mass (0.3 g per plant) and macronutrients (6.9 mg N per plant, 0.7 mg P per plant, 8.6 mg K per plant, 4.9 mg Ca per plant, 2,6 mg Mg per plant, and 0.3 mg S per plant) at the vegetative growth stage (< 49 DAE). Those accumulations increased, mainly after 63 DAE, and the daily accumulation rate was crescent up to 94 DAE (dry mass - DM), 89 DAE (N and P), 98 DAE (K), 95 DAE (Ca and S), and 93 DAE (Mg), when there was accumulation of 26.3 g DM per plant, 402.6 mg N per plant, 45.6 mg P per plant, 359.3 mg K per plant, 337.6 mg Ca per plant, 71.9 mg Mg per plant, and 20.9 mg S per plant. N and K had the highest rates and, consequently, were the most required and accumulated in greater amounts in plant tissues of arrowleaf sida.

Depressive symptoms and harmful alcohol use in hepatitis C patients: prevalence and correlates

Introduction It is important to understand the characteristics and vulnerabilities of people who have hepatitis C because this disease is currently an important public health problem. The objective of this study was to estimate the prevalence of depressive symptoms and harmful alcohol use in patients with hepatitis C and to study the association between these outcomes and demographic, psychosocial and clinical variables. Methods This cross-sectional, descriptive and analytical study involved 82 hepatitis C patients who were being treated with pegylated interferon and ribavirin at a public university hospital. The primary assessments used in the study were the Alcohol Use Disorders Identification Test and the Beck Depression Inventory. Bivariate analyses were followed by logistic regression. Results The prevalence of depressive symptoms was 30.5% (n=25), and that of harmful alcohol use was 34.2% (n=28). Logistic regression analysis showed that individuals who were dissatisfied with their social support (OR=4.41; CI=1.00-19.33) and were unemployed (OR=6.31; CI=1.44-27.70) were at a higher risk for depressive symptoms, whereas harmful alcohol use was associated with the male sex (OR=6.78; CI=1.38-33.19) and the use of illicit substances (OR=7.42; CI=1.12-49.00). Conclusions High prevalence rates of depressive symptoms and harmful alcohol use were verified, indicating vulnerabilities that must be properly monitored and treated to reduce emotional suffering in this population.

A influência do alongamento prévio no pico de torque e na taxa de desenvolvimento de força

The objective of this study was to investigate the influence of previous active static stretch on the peak torque (PT) and rate of force development (TDF) during isokinetic concentric contractions at 60 and 180.s-1 in active individuals. Twelve active subjects with ages between 18 and 30 years participated of this study. The individuals were submitted in different days to the following tests: 1) Familiarization session to the isokinetic dynamometer; 2) Five maximal isokinetic concentric contractions for knee extensors at each angular velocity (60 and 180.s-1) to determine PT and TDF (Control), and; 3) Two active static stretching exercises for the dominant leg extensors (10 x 30 s for each exercise, with 20 s of rest). After the stretching, the isokinetic test was repeated (Post-Stretching). The conditions 2 and 3 were performed in random order. There was no significant modification after the stretch exercises on the PT, angle and time at which the PT was attained, at 60 and 180º.s-1. In the same way, there was no significant modification on the TDF and angle at which the maximal TDF was attained in both angular speeds. In other way, the time to attain maximal TDF (TTDF) at 180º.s-1 was significantly lower after the stretching (Pre - 98.3 ± 27.5 ms and Post - 86.6 ± 30.2 ms). There was significant modification on the torque (60 and 180º.s-1) and time (60º.s-1) at different delta of angle variations, obtained at 60º.s-1 at Control and Post-Stretching conditions. However, there was significant reduction of time after the stretching exercises on delta of angle variations of 90-88º (Pre - 46.6 ± 6.5 ms and Post - 44.1 ± 5.1 ms), 88-85º (Pre - 65.8 ± 7.9 ms and Post - 63.3 ± 4.9 ms) and 85-80º (Pre - 93.3 ± 7.7 ms and Post - 90.0 ± 4.2 ms) at 180º.s-1. With base on these data, it is possible to conclude that PT and TDF do not modify after static stretching, irrespectively on the speed...(Complete abstract click electronic access below)
