Efeito do estresse hídrico e salino na germinação e vigor de sementes de maxixe

The objective of this work was to evaluate the germination and vigor of two lots of gherkin seeds in different osmotic potentials using polyethylene glycol (PEG 6000) and sodium chloride (NaCl). Seeds of the 'North' cultivar were sown in germitest paper moistened in solutions of polyethylene glycol and sodium chloride in osmotic potentials of 0, -0.3, -0.6 and -0.9MPa. The experimental design was completely randomized in a factorial 2x4 design (solutions x osmotic potential), with four replications. Seed vigor was evaluated by the germination test, first germination count, length and dry weight of root and hypocotyl. It is concluded that the reduction in osmotic potential from -0.3MPa induced by PEG 6000 and NaCl reduces the germination and vigor of gherkin's seeds. The osmotic stress induced by PEG 6000 produced more severe effects than saline in physiological quality of gherkin's seeds.

A educação musical sob a perspectiva da pedagogia histórico-crítica

Agrupamentos Sonoros Plenos na Música de Simultaneidades Acústicas e Estruturais

The present article reflects about the concepts of linearity, space and acoustic complexity in the definition of sound grouping as a criticism to the linear concept of phraseology mainly when applied to the music of imitative texture or of complex simultaneities. It takes as examples works by Bach, Josquin des Prez and a fragment of "Lontano" by Ligeti, to study them in two distinct dimensions, simultaneous and interconnected: the acoustic dimension with its entire spectral complexity and the relational dimension which establishes the interaction among the figures in voices and texture layers with some kind of acoustic and structural simultaneity.

As escolas vocacionais e o terceiro ambiente de Hargreaves

The article refers to an official school experience which was developed in the Brazilian education in the 60's - the vocational schools. These schools enabled an artistic-musical learning experience which would be less technicist and autocratic, contributing in a satisfactory way to the future performing formation of the students. In addition to the historical report, the text refers to the British educator D. Hargreaves, who researched on the importance of the "third environment" in the musical learning and on the relationship existing between the internal and the external cognitive process. The text is part of the Master or Arts dissertation which is being carried out in the IA-UNESP (Institute of Arts - State of São Paulo University). The musical-theoretical foundations were provided by the ideas of D. Hargreaves, Sigurd Rascher, Yehudi Menuhi, among others, and by some researchers in the area of education. It is justified on the grounds of the present moment experienced by the musical teaching in face of the approval of Law n(o) 11.769/2008.

A Aplicabilidade da Pesquisa-ação na Educação Musical

Action-research is a model of scientific investigation which is not widely used in musical teaching, even considering its relevant application in the social sciences. David Tripp (2005) classifies it as a type of action-investigation which is used to define any process that follows a cycle where the practice is improved by the systematic oscillation from acting in the field of practice to investigating into it. With the approval by the Brazilian National Congress of Law 17,769, on August 18, 2008, and with the supplementary legislation, we understand that its use in the musical education would be beneficial. This justification has motivated the writing of this article, which approached the characteristics, functions and usefulness of the action-research. The consulted authors were, among others, D. Tripp, M. Thiollent, Maria A. Franco, G. Morceau, and Maria G. de Miranda. Two examples of Master's dissertations which adopted this type of research were mentioned.

A Educação Musical Brasileira e Três Modelos Explicativos de Mundo: em busca de significados

In this paper we study the main modalities of music education in Brazil and how they can be compared to different views worldwide. Recognition that modern practices in music education are inserted in contemporary knowledge paradigms shows their relevance to a changing world. According to this contemporary paradigm the practices included herein point to alternatives in the relationship between men and themselves, men and other men and men and the environment. They also encourage cooperation, the relationship among the arts, the conduction of actions ruled by the principles of ecology and the recovery of values lost or weakened.

Representação da morte feminina em L`Orfeo e Il Combattimento di Tancredi et Clorinda de Claudio Monteverdi

This paper refers to issues related to the harmonic language of Claudio Monteverdi, its harmonic procedures and resulting melodic movements, its use as a dramaturgical resource and its potential allegorical meanings, based on theories and classifications of modes of the sixteenth and seventeenth centuries.
