The relationship intensity, duration and frequency is very important for the hydraulic project’s development, mainly in regions where there is no study updated data. This paper objective was to determine the intensity-duration-frequency curves at Rio Grande do Sul hillside, in order to provide tools for hydraulic structures design and hydrological studies in the region. For the return periods 2, 5, 10, 20, 25, 50 and 100 - year precipitation determination was used Gumbel’s and log-normal statistical distributions, using the Rain Relationship Duration Method for 20 rainfall stations. For Gumbel’s distribution data adherence verification, was used the Kolmogorov-Smirnov adhesion tests and Chi-Square adhesion, with, 5% significance level. The general IDF equation coefficients a, b, c and d were obtained through non-linear regression and the adjustment quality was measured by both determination coefficient and standard error. Different intense rainfall curves were obtained with the methodology applied, for the region, each one shows a good parameters adjustment, important tool for extreme precipitations estimating.

A gestão de cheias em bacias hidrográficas brasileiras deve ser discutida e priorizada, porém o cenário atual indica lacunas quanto às informações hidrológicas com variabilidade espacial e temporal condizentes. A modelagem probabilística de eventos extremos de precipitação, buscando a extrapolação para uma frequência e duração, pode servir como excelente ferramenta de análise e tomada de decisões. O objetivo principal deste trabalho foi analisar o ajuste de diferentes modelos probabilísticos a séries de precipitação máxima diária anual no Rio Grande do Sul. Séries pluviométricas de 342 estações foram ajustadas às distribuições Log-Normal a 2 e 3 parâmetros e Gumbel e a adequação foi realizada pelos testes de Kolmogorov-Smirnov e Qui-Quadrado. Todas as distribuições de probabilidade consideradas foram adequadas; entretanto, a distribuição Log-Normal a 3 parâmetros apresentou os melhores ajustes segundo os resultados do teste Qui-Quadrado. Os parâmetros das distribuições de probabilidades apresentaram variabilidade ao longo do estado e forte relação com a localização, sugerindo que a regionalização de chuvas intensas pode ser empregada no Rio Grande do Sul como excelente ferramenta de gestão.

ABSTRACT Although several studies have evaluated the intensity-duration-frequency relationships of extreme rainfall events, these relationships under different seasonal conditions remain relatively unknown. Thus, this study aimed to determine whether the intensity-duration-frequency relationships obtained seasonally from the rainfall records in the winter and summer represent the maximum rainfall events for the city of Pelotas, Rio Grande do Sul state, Brazil. Pluviographic data from 1982 to 2015 were used to create two seasonal series: one for the summer from December 21 to March 20 and the other for the winter from June 21 to September 22. These seasonal relationships were compared with the annual pluviographic data. The intensity, duration, and frequency relationships obtained from the summer rain data adequately represented the maximum rainfall in Pelotas, Rio Grande do Sul state, Brazil. The maximum intensity values of rainfall obtained from the relationship of intensity, duration, and frequency for the winter did not adequately encapsulate the occurrence of rain with greater intensities.

BACKGROUND: Ephelides are small hyperpigmented macules common in the skin, presenting as areas with increased melanin production. Ephelides are observed in genetically predisposed individuals, particularly fair-skinned people highly susceptible to sunburn. OBJECTIVES: This study aimed to determine the prevalence of lip and perioral ephelides in 362 beach workers in the city of Natal (Rio Grande do Norte) and to investigate potential associations with sociodemographic, occupational and general health. METHODS: For this purpose clinical tests were performed by calibrated examiners in the epidemiological area around the lips and the area bounded laterally by the nasolabial groove and at the bottom by the chin. A questionnaire was completed and assessed. The possible associations between sociodemographic variables, occupational and general health with the presence of lip and perioral ephelides were evaluated by chi-square test for a significance level of 5%. RESULTS: Approximately one third of the workers were affected by perioral ephelides (33.7%) and around a quarter of them by lip ephelides (24.0%). Gender was the only variable significantly associated with the presence of perioral ephelides (p = 0.002), unlike lip ephelides which proved to be significantly associated with habits (p = 0.036) and alcoholism (0.030). CONCLUSIONS: The prevalence of ephelides in lip and perioral region was high in the study population, with gender and certain habits associated with its occurrence.

AbstractA statistical analysis is performed on natural events which can produce important damages to insurers. The analysis is based on hurricanes which have been observed in the United States between 1954 et 1986.At first, independence between the number and the amount of the losses is examined. Different distributions (Poisson and negative binomial for frequency and exponential, Pareto and lognormal for severity) are tested. Along classical tests as chi-square, Kolmogorov-Smirnov and non parametric tests, a test with weights on the upper tail of the distribution is used: the Anderson – Darling test.Confidence intervals for the probability of occurrence of a claim and expected frequency for different potential levels of claims are derived. The Poisson Log-normal model gives a very good fit to the data.
