Isobutyl amides - potent compounds for controlling Diatraea saccharalis

BACKGROUND: A dichloromethane-methanol extract of the seeds of Piper tuberculatum Jacq. (Piperaceae) and two isobutyl amides, 4,5-dihydropiperlonguminine (1) and pellitorine (2), which were isolated by chromatographic methods, were assayed for their lethality against the sugarcane borer Diatraea saccharalis F. (Lepidoptera: Pyralidae).RESULTS: Bioassays were carried out with fourth-instar caterpillars through topical application of test solutions to the dorsal surface of the prothorax, and dose-response correlations were determined. Significant insect mortalities were observed 24, 48 and 72 h after treatment at concentrations of >= 100 mu g insect(-1). The LD(50) and LD(90) values for compound 1 were 92.83 and 176.50 mu g insect(-1), and for compound 2 they were 91.19 and 184.56 mu g insect(-1).CONCLUSION: According to the LD(50) and LD(90) for compounds 1 and 2, it can be inferred that the values reflect an acute lethal response to both compounds, based on interaction(s) of the toxicants with a primary target or series of targets. Thus, the amides were demonstrated to have potential value in the control of the sugarcane borer. (C) 2008 Society of Chemical Industry

John Dewey e o pensamento educacional brasileiro: a centralidade da noção de movimento

O trabalho analisa artigos publicados em periódicos educacionais brasileiros entre 1930 e 1960, cujos temas são educação, democracia, filosofia, ciência e verdade, entre outros, desenvolvidos segundo concepções de Dewey. em todos, ocupam posição central as noções de mudança e transformação, em oposição a estabilidade, fixidez e permanência. O objetivo é mostrar a relevância da noção de mundo em movimento, tanto para os brasileiros quanto para Dewey.

Study of spore germination in Thelypteris-dentata (forssk) e-st-john

The spore germination in Thelypteris dentata was studied and the optimum temperature of 25 C was determined by the maximum percentage germination and the highest germination index. The necessity of continuous white light irradiation and reversion of spore germination by subsequent far-red light irradiation indicate the involvement of phytochrome in the control of the process. The dependence of induction of spore germination to the continuous white light low irradiance confirms the phytochrome control through the low fluence response.

O discurso psicològico de john dewey

This work examines the discourse of the American philosopher and educator John Dewey (1859-1852) about human nature, adopting as reference the book Human nature and conduct: an introduction to Social Psychology. In this book, published in 1922, Dewey discusses fundamental concepts of Psychology - instinct, habit, intelligence, and others - and proposes a new psychological science; the author's elaborations cover the fields of philosophy, psychology and education. The methodology to analyze his discourse follows the studies developed by the Research Group Rhetoric and Argumentation in Pedagogy. Such studies are based on Chaïm Perelman's and Stephen Toulmin's theories.
