A caracterização das águas superficiais e intersticiais nos estuários é fundamental para desvendar as condições ambientais, qualidade ambiental e mudanças sazonais, que podem ocorrer em espaço menor como é o caso do furo da ilha de Colares. Este trabalho tem como objetivo mostrar a influência da sazonalidade nas águas estuarinas na foz Norte e Sul do furo da ilha de Colares e da contribuição das águas intersticiais para as águas superficiais. Os parâmetros físicos e químicos, e nutrientes contemplados são: índice pluviométrico (IP), temperatura, salinidade, pH, condutividade elétrica, sólidos totais dissolvidos, material particulado em suspensão, oxigênio dissolvido, profundidade de Secchi, nitrato, nitrito, N-amoniacal, fosfato, silicato e sulfato. A determinação destes parâmetros ocorreu de forma simultânea em cada foz do furo de Colares durante um ciclo de maré (13 horas) nos periodos chuvoso (10/04/2013) e menos chuvoso (05/10/2013). Os resultados revelam que a sazonalidade interfere nas condições abióticas das águas estuarinas do furo da ilha de Colares e deduz que o IP é o fator de maior efeito das mudanças dos parâmetros físicos e químicos e, sobretudo o maior responsável na mobilidade, disponibilidade e distribuição dos nutrientes dissolvidos, que foram encontrados em concentrações maiores no período chuvoso. Ainda os nutrientes nitrato e N-amoniacal foram considerados muito elevados na foz Norte, possivelmente relacionados com a influência de atividades antropogênica. Contudo foram considerados dentro dos limites estabelecidos pela Resolução 357 da CONAMA/05. Na foz Sul ocorreu níveis de pH fora do padrão estipulado pela Resolução da CONAMA, porém o fenômeno foi considerado natural visto que este em especifico se encontra distante de atividades antropogênicas. No período menos chuvoso o N-amoniacal foi considerado ausente na foz Norte e Sul. O manguezal foi considerado como fonte de salinidade, silicato e sulfato para as águas superficiais.

Objective: This study aims to investigate the effects of low-level laser therapy (LLLT) on biceps brachi muscular fatigue in 20 young females. Background data: Exhausting physical activity leads to muscular fatigue, which could decrease muscular strength, and may cause impairment in motor control and muscle pain. Several biochemical and biophysical resources have been studied in an attempt to accelerate the recovery of muscle fatigue. Among these, LLLT is emphasized. Methods: Twenty subjects were randomized in one laser group and one placebo group in two sessions of a crossover design experimental procedure; the second session taking place within 7 days of the first. In the first session, subjects underwent a collection of surface electromyographic (SEMG) data of the biceps brachii muscle, followed by active or placebo LLLT at the same muscle, followed then by another EMG sample of biceps brachii. Blood samples were collected five times during the experimental procedure. Second session procedures were identical to the first, with exception of LLLT, which was the opposite of the first session. The fatigue protocol consisted of 60sec of elbow flexion-extension movement performed with 75% of one maximum repetition. Blood lactate, EMG fatigue, and the number of elbow flexion-extension repetitions during the fatigue protocol were used to evaluate the effects of laser therapy (808nm wavelength, 100mW output power, power density of 35.7 W/cm(2), 70sec each point and 7J/point on eight points). Results: No statistical differences were found for eletromyographic fatigue and blood lactate values between groups. Mean numbers of elbow flexion-extension repetitions were 22.6 +/- 7.58 after placebo, and 25.1 +/- 9.89 after active LLLT group, but these differences were not statistically significant (p=0.342). Conclusions: LLLT had limited effects on delaying muscle fatigue in a young female sample, although a tendency was observed in the active laser group toward showing lower electromyography fatigue of biceps brachii muscle. No intergroup differences were found in the number of muscle contractions and lactate concentration.

The objective of this paper is to relate the set of financial ratios that are directly related to the success of public traded companies using a methodological approach and the method of multivariate principal component analysis. This study consists in the use of profitability ratios, debt and liquidity, to define the relationship between financial ratios with the best public traded companies listed in the magazine Exame Melhores e Maiores of 2013. Multivariate analysis was used to reduce the dimensionality of multivariate data, making linear combinations of the original variables (financial ratios) and express the data in principal components that result in new variables that contains much of the original data. As a result, we got the optimal number of five principal components, and both represent 95.6% of the original data. Among of all financial ratios, we can highlight the direct relationship between profitability ratios for the first principal component, and the direct relationship between the liquidity ratios, both inversely related with non-capital participation rates and degree indebtedness to the second principal component

The motivation in the sport has been one of the most studied subjects nowadays, as much that some authors say that the motivation is the base for the success of an athlete, that is, the psychological part must also well be stimulated so that if it reaches the maximum level of concentration during a game it will obtains the expected result. Tennis is one of the sports that more grew in recent years, and together with this fast ascension also increased the number of interested in researching in this area of the Psychology of the Sport. The present study has as objective to begin the adaptation and validation of the interest scale and to analyze the influence of the motivational orientation of the athletes in the sportive performance of the Tennis through the application of scale Teosq – Task and Ego Orientation in Sport Questionnaire (DUDA, 1992), translated, adapted and validated by Hirota and De Marco (2006), where we can identify if the individual is guided for a task or an ego’s goal. This research was carried through in a situated academy of Tennis in the City of Cotia – SP – Brazil, counting on the participation of 20 citizens with age between 09 and 18 years of both the practicing sexes of Tennis. The calculation of the Alpha Coefficient of Cronbach was adopted as statistical method, in order to identify the trust worthy and validity of the instrument beyond the average of each orientation, to be able to verify the athlete’s motivational orientation. For the analysis of the results, the Alpha Coefficient was observed high, compared with previous studies, reaching values of orientation for the ego of 0,90, and 0,70 of orientation for task. They had been registered the following averages, 4,20 (+0,93) and 2,42 (+0,85), respectively of orientation for task and ego. With those results we can point that, the scale applied with the proposal to identify the motivational orientation of the athletes of Tennis, revealed efficiency, and trust worthy in its application, and in accordance with the results, the athletes are guided for task, revealing self-determination, selfconfident, more creative and they judge its success for the quality of the carried through work.

OBJECTIVE To determine the incidence of type IV prostatitis in patients with kidney transplantation receiving an immunosuppression regimen and to compare it with that of a nonimmunosuppressed control group. METHODS We retrospectively reviewed 216 electronic charts of patients who had undergone surgical treatment for benign prostatic hyperplasia from August 2000 to January 2006. Of the 216 patients, 183 did not receive immunosuppressive therapy and were included in the control group (group 1). The other 33 patients had undergone kidney transplantation and were included in the study group (group 2). The patient data were accessed for age at surgery, International Prostate Symptom Score, prostate volume, preoperative serum prostate-specific antigen level, history of acute urinary retention, and surgical approach (open vs transurethral resection of prostate). Histologic findings from the surgical specimens were also recorded. RESULTS The mean age at surgery, mean serum prostate-specific antigen level, mean prostate volume, and mean International Prostate Symptom Score were not significantly different between both groups. However, histologic evidence of chronic prostatitis was obtained in 145 surgical specimens (78%) from group 1 and in just 3 specimens from group 2 (9%; P < .001). Moreover, nonimmunosuppressed patients had a 38.2 times greater risk of presenting with prostatitis than did the immunosuppressed patients. CONCLUSION Imunnosuppresion therapy in kidney transplantation has a protective factor in the prostatitis incidence. UROLOGY 79: 662-664, 2012. (C) 2012 Elsevier Inc.

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Purpose: To analyze the outcome of deceased donor recipients given priority in allocation due to lack of access for dialysis and compare this data to the one obtained from non-prioritized deceased donor kidney transplant recipients. Materials and Methods: we reviewed electronic charts of 31 patients submitted to kidney transplantation that were given priority in transplantation program due to lack of access for dialysis from January 2005 to December 2008. Immunological and surgical complications rates, and grafts and patients survival rates were analyzed. These data were compared to those obtained from 100 regular patients who underwent kidney transplantation without allocation priority during the same period. Results: Overall surgical complication rate was 25.8% and 27% in the patients with priority in allocation and in the non-prioritized patients, respectively. There was no statistical significant difference for surgical complications (p = 1.0), immunological complications (p = 0.21) and graft survival (p = 0.19) rates between the groups. However, patient survival rate was statistically significant worse in prioritized patients (p = 0.05). Conclusions: patients given priority in allocation owing to lack of access for dialysis have higher mortality rate when compared to those non-prioritized.
