Scalar-bipolar asymptotic modules for solving (2+1)-dimensional nonlinear evolution equations with constraints

An infinite hierarchy of solvable systems of purely differential nonlinear equations is introduced within the framework of asymptotic modules. Eacy system consists of (2+1)-dimensional evolution equations for two complex functions and of quite strong differential constraints. It may be interpreted formally as an integro-differential equation in (1+1) dimensions. © 1988.

História e Filosofia da Biologia como ferramenta no ensino de evolução na formação inicial de professores de Biologia

By establishing a relationship among several sections of Biology, the theory of the evolution enables a more systemized and less fragmented education of this science. However, students seem to have difficulties of understanding the concept of biological evolution, by virtue of misunderstanding conceptual and historical data present in textbooks, among other causes. One of these mentioned distortions is the shock between Lamarck and Darwin’s ideas. We aimed, in this work, to investigate the understanding of Biology’s students in pre-service teachers education concerning the Lamarck and Darwin’s theories at different moments of the Evolution discipline. For this, some steps had been followed: 1) Verification of the previous conceptions; 2) Elaboration of a pedagogical material, containing diverse historical texts of primary and secondary sources; 3) Debates in two didactic modules, using the pedagogical material elaborated; 4) Analysis of the conceptions constructed by the students, from the didactic intervention. The results obtained show the preconceptions of the students interviewed, concerning the Lamarck and Darwin’s theories, resemble the explanations presented in textbooks and the insertion of historical texts in the Evolution lessons can be an interesting strategy to construction of knowledge of this theme

Capacidad de uso de la tierra en la cuenca de la Corriente del Lobo, Itatinga, São Paulo, Brasil

The objective of the research was to define the classes of use capacity of 2403.25 ha in the basin of the Corriente del Lobo - Itatinga (SP), (22°03'56" to 22°59'12" of latitude S and 48°38'47" to 48°41'25" of longitude W Gr.). The soil use capacity was obtained by using the SIG IDRISI 32 crossing the documents of steepness and soils and the document of judgment of classes of soil use capacity and of the utilitarian rising of the physical milieu. The classes and subclasses areas of use capacity presented the following values: IIIa - 68.60 ha (2.85%), IIIe,s - 1919.15 ha (79.86%); IIIe - 210.60 ha (8.76%); IVe - 3.38ha (0.14%); IVe,s - 157.42 ha (6.55%) and VIe,s - 44.10 ha (1.84%). The lands of the basin were distributed in three classes (III, IV and VI) and six subclasses but the biggest extension (79.9%) belonged to the subclass IIIe,s. The modules of the IDRISI allowed to discriminate, mapping and to quantify quickly the soil use capacity of the areas of classes and subclasses in the basin.
