Abstract: the hydrologic frequence analysis makes possible to know the magnitude ofan eventfor a given ocorrency of frequence. it aiso identify wheather the observed data follow some theoretical distribuition of probability. the objective ofthis study was to adjust the observed data ofannual rainfall, as well maximum and minimum monthly rainfall, in several probability leveis, for the agroclimate stations of pelotas, morro redondo, domingos petroline and rio grande. the series ofannual rainfall data of pelotas, morro redondo, domingos petroline and rio grande station were adjusted adequately to the normal, log-normal, log-normal and gumbel distribuitions of probability, respectively. the series of annual maximum were adequate to the gumbel, log-normal. gumbel and log-normal distribuitions of probability, respectively. the series of annual minimum for rio grande station was not homogeneous by the "run-test".

Abstract: In the Universal Equation of Soil Loss (USLE), erosivity is the factor related to rain and express its potential to cause soil erosion, being necessary to know its kinetic energy and the maximum intensities of rain in duration of 30 min. Thus, the aim of this study was to verify and quantify the impact of the rain duration, considering 15 and 30 min, on the USLE erosivity factor. To achieve this, 863 rain gauge records were used, duiring the period of 1983 to 1998 in the city of Pelotas, RS, obtained from the Agrometeorological Station - Covenant EMBRAPA/UFPel, INMET (31o51′S; 52o21′O and altitude of 13,2 m). With the records, it was estimated the erosivity values from the maximum intensities of rain during the period evaluated. The average annual values of erosivity was 2551,3 MJ ha-1 h-1 ano-1 and 1406,1 MJ ha-1 h-1 ano-1, for the average intensities of 6,40 mm h-1 and 3,74 mm h-1, in durations of 15 and 30 min, respectively. The results of this study have shown that the percentage of erosive rainfalls in relation to the total precipitation was of 91.0%, and that the erosivity was influenced by the duration of the maximum intensity of rain.= Na Equa o Universal de Perdas de Solo (EUPS) a erosividade é o fator relacionado à chuva e expressa o seu potencial em provocar a eros o do solo, sendo necessário que se conhe a a energia cinética da mesma e as máximas intensidades da chuva na dura o de 30 min. Objetivou-se com este trabalho verificar e quantificar o impacto da dura o da chuva, considerando 15 e 30 min, sobre o fator erosividade da EUPS. Para tanto foram utilizados 863 registros pluviográficos de chuva, no período de 1983 a 1998 da localidade de Pelotas, RS, obtidos na Esta o Agroclimatológica – Convênio EMBRAPA/UFPel, INMET (31o51′S;52o21′O e altitude de 13,2 m). Com os registros foram estimados os valores de erosividade a partir de intensidades máximas de chuva nas dura es consideradas. Os valores médios anuais de erosividade foram 2551,3 MJ ha-1 h-1 ano-1 e 1.406,1 MJ ha-1 h-1 ano-1, para as intensidades médias de 6,40 mm h-1 e 3,74 mm h-1, nas dura es de 15 e 30 min, respectivamente. Os resultados do presente trabalho permitem concluir que o percentual das chuvas erosivas em rela o ao total precipitado foi de 91,0% e que a erosividade foi influenciada pela dura o da intensidade máxima da chuva.
A Caridade criando hospitais em Minas Gerais (Brasil) - séculos XVIII-XX
Cássia Marques,Rita de;
Dynamis , 2011, DOI: 10.4321/S0211-95362011000100006
Abstract: o artigo é fruto de uma pesquisa sobre o patrim?nio cultural da saúde em minas gerais (brasil) e se dedica a compreender a constru??o de hospitais fomentados pelas a??es caritativas de católicos, leigos ou religiosos, entre os séculos xviii e xx. o movimento católico leigo sempre foi forte em minas gerais favorecido pelas proibi??es da coroa portuguesa em torno da livre circula??o de religiosos, considerados suspeitos de contrabandear o ouro das minas. a primeira santa casa, a de vila rica, surge de uma irmandade. a caridade também é o mote de outro grupo de leigos que teve grande importancia no brasil, especialmente no século xx - os vicentinos. assinala-se ainda a divulga??o dos ideais de caridade de frederico ozanam com base na obra de s?o vicente de paula. por vicentinos é preciso entender tanto o movimento leigo abrigado nas conferências da sociedade s?o vicente de paula, como os religiosos: os padres lazaristas e as irm?s vicentinas. o terceiro grupo estudado é o dos médicos católicos, fruto do associativismo profissional incentivado pela igreja católica. as santas casas com suas irmandades, os vicentinos e o associativismo católico integram movimentos reconhecidos no mundo todo. nesse contexto social de grande participa??o católica nas obras de caridade, restava aos médicos integrar o movimento, com o desprendimento dos atendimentos muitas vezes gratuitos e com o esfor?o para criar hospitais para a popula??o carente. no século xx, a capital de minas gerais, embora fruto de decis?o de republicanos e positivistas portadores dos ideários da modernidade, continuou se valendo da caridade crist? para tratar dos pobres.
Gênero, infancia e rela??es de poder: interroga??es epistemológicas
Marchi, Rita de Cássia;
Cadernos Pagu , 2011, DOI: 10.1590/S0104-83332011000200016
Abstract: this article relates the peripheral positions of woman and child in the scientific field and the current epistemological difficulties towards the emancipation of childhood as a conceptually autonomous sociological category. these difficulties are similar to the resistance encountered some years ago by "feminist studies" to establish gender as a new category of analysis. childhood is a phenomenon permeated, in the social field, by asymmetric relations of power and action between generations and, in the scientific field, by the adult-focused and predominantly masculine (androcentric) perspective of knowledge.
Plant reproductive phenology and dispersal patterns after natural regeneration in a limestone mining spoil banks
Frenedozo, Rita de Cássia;
Brazilian Archives of Biology and Technology , 2004, DOI: 10.1590/S1516-89132004000200014
Abstract: studies were carried out on the phenological patterns and dispersion of a plant community developed naturally after limestone mining operations, in accumulated materials of wastes (spoil banks). the objectives were to focus the seasonality of plant reproductive in a degraded environment; to analyze the community according to dispersal syndrome and to know about plant resources for the animals monthly observations of flowering and fruiting patterns of the community were done, comparing the herbaceous, shrubs and woody species. proportion of anemochorous and autochorous was higher in the herbaceous and shrubby strata. the zoochorous ones, on the contrary, were more frequent in the woody stratum. this study showed that natural introduction of the animals at the unreclaimed area, increased the chances for long time, of preserving the plant species since they are pollinated and dispersed their seeds.
O ?ofício de aluno? e o ?ofício de crian?a?: articula??es entre a sociologia da educa??o e a sociologia da infancia
Marchi,Rita de Cássia;
Revista Portuguesa de Educa??o , 2010,
Abstract: this article establishes the relationships between what is known as the "paradigm crisis" in the sociology of education (sed) in the 90?s and the appearance of a new paradigm for the social studies of childhood. as the central elements of this new paradigm we have the principles of childhood social construction and of child-actor and the requirement of the conceptual autonomy of childhood. the initial separation between the sociology of education and the social studies of childwood was due to the fact the sed has been traditionally focused, both on its structural-functional side and on the reproduction theories space as well, on the macro-relationships between school and society. the "child task" and the "student task" have here a complex existence whose clarification reveals the paths which have been exploited in the theoretical-methodological constructions inside these disciplines and in their tense articulations.

Revista Portuguesa de Educa??o , 2010,
Abstract: This article establishes the relationships between what is known as the "paradigm crisis" in the Sociology of Education (SED) in the 90's and the appearance of a new paradigm for the social studies of childhood. As the central elements of this new paradigm we have the principles of childhood social construction and of child-actor and the requirement of the conceptual autonomy of childhood. The initial separation between the Sociology of Education and the social studies of childwood was due to the fact the SED has been traditionally focused, both on its structural-functional side and on the reproduction theories space as well, on the macro-relationships between school and society. The "child task" and the "student task" have here a complex existence whose clarification reveals the paths which have been exploited in the theoretical-methodological constructions inside these disciplines and in their tense articulations.
