Em um sistema de abastecimento de água, a rede de distribuição permite a chegada de água em condições adequadas aos consumidores e, para isso, é necessário um criterioso dimensionamento. Neste trabalho, foi elaborado um método para dimensionar redes de distribuição de água por meio de uma rotina computacional que combina gradientes hidráulicos obtidos por Hazen-Williams com simulações realizadas através do EPANET com a Teoria dos Grafos. Quatro redes foram dimensionadas e realizou-se uma comparação técnica e econômica entre a metodologia desenvolvida e um método convencional. Ambos buscaram respeitar os parâmetros hidráulicos determinados, encontrando pressões similares, no entanto, o método proposto alcançou resultados mais econômicos, sendo o recomendado.

English Journal Writing on Moodle for EFL College Learners

The present study is to explore the effect of Moodle English journal writing for general purposes on language learners' writing performance, conjunction preferences and English self-efficacy. Self-efficacy, claimed by a large number of researchers, has a direct and powerful influence on learners' academic accomplishments. However, there is little research on enhancing the level of English self-efficacy and writing performance through keeping E-journals, particularly in an EFL context where the learners develop both native and foreign languages and cultures. Multiculturalism should be taken into consideration before language curricula are designed. The participants, in the study, 40 non-English-majored college students in Taiwan, were required to keep a journal through Moodle. The findings of the study reveal that the participants' general perceived English abilities and writing confidence were enhanced after their efforts on Moodle E-journal writing. From the pieces of writing, they present both characteristics of the native and target languages and cultures.

„Philosophical Transactions of the Royal Society” Henry’ego Oldenburga z lat 1665–1677 i naukowe doniesienia z Rzeczypospolitej ze szczególnym uwzględnieniem prac Jana Heweliusza

HENRY OLDENBURG’S PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY 1665–1677 AND SCIENTIFIC REPORTS FROM THE REPUBLIC OF POLAND WITH SPECIAL CONSIDERATION OF THE WORKS OF JAN HEWELIUSZThe purpose of this paper is to reveal the presence in the pages of the fi rst scientifi c English journal The Philosophical Transactions of the scholars associated with the Republic of Poland or conducting scientifi c research or experimental observations on the Polish territory. The subject of articles edited and published by Henry Oldenburg during the years 1665–1677 will be outlined, as well as the dynamics of research in the Republic of Poland. Analized were original scientifi c texts sent from Poland to the editor of the journal during the years 1665–1677, as well as the citations of these works or studies from the area of Republic of Poland. Studies have shown that the most active author was Jan Heweliusz — astronomer from the Free Royal City Gdańsk. Unfortunately, other important works of Polish scientists were not published in the journal. The reasons for this lack should be sought in many sorts of factors in the history of Poland in the 17th century.
