There are several mechanical models to describe the DNA phenomenology. In this work the DNA denaturation is stu- died under thermodynamical and dynamical point of view using the well known Peyrard-Bishop model. The thermody-namics analysis using the transfer integral operator method is briefly reviewed. In particular, the lattice size is discussed and a conjecture about the minimum energy to denaturation is proposed. In terms of the dynamical aspects of the model, the equations of motion for the system are integrated and the results determine the energy density where the denatura- tion occurs. The behavior of the lattice near the phase transition is analyzed. The relation between the thermodynamical and dynamical results is discussed.

Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

We show that the parametrized Wave-Packet Phase Space representation, which has been studied earlier by one of the authors, is equivalent to a Squeezed States Phase Space Representation of quantum mechanics. © 1988.
