Abstract: O objetivo deste trabalho foi caracterizar a dinamica espa o-temporal do regime fluvial do Rio Paraíba. Para tanto, foram utilizados dados de séries históricas disponíveis no site da ANA, através do sistema de informa es hidrológicas (HIDROWEB). A análise dos dados permitiu verificar que a distribui o é assimétrica e com desvio padr o superior a média, sugerindo ocorrência de regimes extremos. O mês de abril foi, em toda a bacia, o de maior vaz o registrada, seguido pelos meses de mar o e maio. Os meses de menor vaz o foram setembro, outubro e novembro, refletindo a dinamica climática regional. O Rio Paraíba responde rapidamente as fortes chuvas, devido ao predomínio do escoamento superficial na bacia, o que produz hidrogramas de vaz o com “picos”. Contudo, foi confirmada a influência dos a udes na regulariza o da sua vaz o.

Abstract: Globalization has only at first glance a technological sense, but has also reflected the legal, economic, political and social. Among other salient features that sparked this new world order, has been the inauguration of the Internet, which made possible new horizons in various crops, including enabling a new way of hiring. The Internet has been the instrument of great business revolution, unleashing new forms of communication between people (or businesses), with peculiarities in the circulation of information by modifying the traditional ways of making the legal business, which in turn, given the technological innovations , faced with unknowns, and tries to shape in order to ensure legal support to citizens who enjoy this facility. In this context, the law as an instrument of social control, moves gradually.

Abstract: This article presents partial results of a broader study. Here we try to identify how to show the performance of students in problem-solving activities including the ideas associated with fractions, as a function of their level of education. Six hundred and thirty students participated in this research, with an average of ninety per grade, all from the public school system in Pernambuco. The instrument consisted of 10 items including three ideas associated with fractions (part-whole, quotient and operator), varying the type of quantity involved (discretes and continuous). The results show differences in behavior of fifth and sixth grade students when they are asked to vary the type of quantity and the idea of fraction involved in an item. It also was possible to observe that the types of errors made by students present a certain stability with the development of education. Keywords: Mathematics Education. Fraction. Idea of Fraction. Equivalence. Este trabalho apresenta parte dos resultados de um estudo mais amplo3. Aqui buscamos identificar como se comporta o rendimento de alunos em atividades de resolu o de problemas envolvendo as idéias associadas às fra es, em fun o de sua escolaridade. Participaram da pesquisa 630 alunos de escolas públicas de Pernambuco, com uma média de 90 alunos por série. O instrumento constou de 10 itens envolvendo três idéias associadas às fra es (parte-todo, quociente e operador), variando o tipo de quantidade envolvida (discreta e contínua). Os resultados mostram um comportamento diferenciado dos alunos do terceiro Ciclo (quinta e sexta séries) quando se faz variar o tipo de quantidade e a idéia de fra o envolvida no item. Foi possível identificar também que os tipos de erros cometidos pelos alunos apresentam certa estabilidade com o desenvolvimento da escolaridade. Palavras–chave: Educa o Matemática. Fra o.

Abstract: The objective of this study was to determine the physical activity level (PAL) and sedentary behavior of students from the city of Aracaju (SE). A total of 1028 students of both genders participated in the study, with a mean age of 15.38 (2.44) years for girls and 15.24 (2.40) years for boys. Among the sample, 24.7% were children and 75.3% were adolescents, with a mean age of 12.07 (0.88) and 16.39 (1.72) years, respectively. An instrument already used in Brazilian studies was applied to identify the average time (hours) watching TV per day (hTV) and PAL – PAQ-C. Descriptive statistics, t-test for independent samples, Fisher’s exact test and comparison test between two proportions were used for data analysis, with the level of significance set at 5% (p≤0.05). Boys presented a significantly higher physical activity score 2.25 (0.60) than girls. The prevalence of sedentarism was 72.5, 89.3 and 85.2% in the groups of children and adolescents and in the group as a whole, respectively, for girls, and 55.4, 74.8 and 69.8% for boys. No differences in hTV were observed between genders or between sedentary and physically active students (p > 0.05). We conclude that a) there is a high prevalence of “sedentary” and “very sedentary” children and adolescents; b) boys present a higher PAL than girls; c) adolescents are less active than children, and d) the number of hTV is high in the group studied.

Abstract: In this work social, economic and environmental aspects were studied using the concept of programming by commitment, with the objective of structuring an integrated indicator capable of estimating the degree of the environmental quality of the Jiquiri a river basin, BA, composed by the indicator of environmental salubrity, water quality and soil’s protection. For the determination of the environmental salubrity indicator, data of the following variables were collected: existence of treated water supply, disposition and treatment of solid residues, diseases vectors control, the existence of the Agenda 21, socioeconomics data and indices of human development for each municipal district located in the area of the watershed. The indicator of the water quality was structured based on the analysis of water samples collected in eight sampling points along Jiquiri á river and determined by seven parameters. The indicator of soil’s protection was based on the analysis of maps obtained according to the weight of each steepness and land use class. Results indicate that the watershed is in a poor equilibrium condition and suggest the need for structural investments as well as changes in public polices. The methodology used was efficient for this watershed management and could be used as tool for the environmental planning of the region, once it can be adapted to several situations depending on the data availability.

Pesquisa Florestal Brasileira , 2010, DOI: 10.4336/2012.pfb.56.87
Abstract: Este trabalho teve por objetivos caracterizar as propriedades químicas do solo sob plantio de pupunheira (Bactris gasipaes) aos 24, 39 e 48 meses de idade e, quantificar na agroindústria, nessas idades, a produ o de palmito em toletes, em rodelas e picado, em fun o de diferentes espa amentos. Para tanto, em mar o de 2001, foram instaladas duas áreas experimentais localizadas nos Km 7 e Km 10 da Estrada Alexandra-Matinhos, Município de Paranaguá, PR. O delineamento estatístico foi o de blocos ao acaso com parcelas de 100 plantas, quatro tratamentos e seis repeti es. Os tratamentos foram constituídos pelos seguintes espa amentos: 3 m x 1 m ; 2 m x 1 m ; 2 m x 1 m x 1 m (linhas duplas) e 1,5 m x 1 m x 1 m (linhas duplas). Foi feita aduba o com N, P e K na época de plantio e aos 6 ; 9 ; 12 ; 18 ; 21 e 45 meses de idade, totalizando 86 g ; 47,8 g e 67,5 g por planta, respectivamente. Aos 42 meses de idade, foram distribuídos nas entrelinhas de plantio 16 kg de calcário dolomítico, correspondo a, aproximadamente, 2 t.ha-1. Foi possível concluir que: (i) as quantidades de N, P, K e de calcário aplicadas promoveram mudan as nas características químicas do solo; (ii) as densidades entre 5 mil e 6.666 plantas por hectare promoveram as maiores produ es de palmito, nos sucessivos cortes realizados. The present study was developed to characterize the chemical properties of the soil under peach palm (Bactris gasipaes) plantations at 24, 39 and 48 months old, and to quantify the heart-of-palm production on a local industrial scale (packaged in various forms in glass jars). The experiment was set up in two areas, located along the Alexandra-Matinhos Road (km 7 and km 10) near Paranaguá county, State of Paraná, Brazil, in March of 2001. Randomized blocks were used as statistical design, having 100 plants per sample, with four treatments and six replicates. Treatments considering spacing and plant density were: 3 m x 1 m ; 2 m x 1 m ; 2.0 m x 1 m x 1 m and 1.5 m x 1 m x 1 m. Peach palm plants were fertilized at plantation stablishment and at 6 ; 9 ; 12 ; 18 ; 21 and 45 months after planting, totalizing 86 ; 47,8 and 67,5 g per plant of N, P and K, respectively. Dolomite lime was placed between rows at a level of 16 kg, corresponding to 2 ton.ha-1. The results showed that: (i) fertilization with N, P and K and the application of lime changed soil chemical characteristics; (ii) density between 5,000 and 6,666 plants.ha-1 presented bigger heart-of-palm production, in the successive harvests.
