Inclusões Dinâmicas em Escalas Temporais: Existência de Soluções sob a Hipótese de Semicontinuidade Inferior

In this paper we consider the problem of differential inclusion in time scales whose vector field is a multifunction, that is, a function that maps points to sets. It is provided conditions of existence without requiring compactness of the vector field; it is required that the vector field is closed, convex, and lower semicontinuous. In previous work in literature, it is required that the field is either scalar or compact, convex, and has closed graph.

Educação ambiental e contexto escolar: questões para um programa de pesquisas

In this paper are systematized the discussions conducted by GDP "Research in EA and School Context", in VII EPEA, which have had, as its main axis, themes, authors and theoretical perspectives privileged in research presented at the event and declared themselves affiliated to this GDP. The dialogue with researches from previous meetings and other, aims to deepen the questions posed by the research group. The discussions allowed to identify themes and issues that present themselves as significant and challenging for research in EA in the school context, namely the conversion of schools into sustainable educational spaces; public-private partnerships, with great interest from companies and NGOs in school spaces, waving kits with educational materials produced for the school; lack of investment in public policies for teacher training in EA; tendency to an adherence to critical environmental education, without, however, have clear theoretical and methodological commitments under this option.

Relações de Gênero, memória e identidades no Brasil do século XX

Gender relationships focusing on homages to the women of Assis (a town in the center-western region of the state of São Paulo, Brazil) between 1959 and 1994, are discussed. Homages, expressed in monuments, street names, city squares, schools, libraries, Cultural Centers and other places, are based on the activities of women who benefitted the community. They feature lawyers, politicians, journalists, teachers and common citizens that exceeded their personal limitations and conquered a place acknowledged by society (politically invested) so that their names may be inscribed in the city´s public places. However, acknowledgement of female contributions in the construction of the city is not projected at the same pace or speed as that of males who compose the gallery of ‘remembered men’. This fact brings forth the following questions: If the naming of public places were for decades based on gender, what had changed by the end of the 1950s for such a redefinition? What is the true meaning of such homages? Who are these women and what do they represent?

Cherubism: clinicoradiographic features and treatment

Cherubism is a congenital childhood disease of autosomal dominant inheritance. This disease is characterized by painless bilateral enlargement of the jaws, in which bone is replaced with fibrous tissue. The condition has sui generis clinical, radiographic and histological features, of which the clinician should be aware for a better differential diagnosis in the presence of a fibro-osseous lesion affecting the bones of the maxillomandibular complex. The purpose of present paper was to review the literature and to report the most important aspects of cherubism in order to facilitate the study of this disease. Literature was reviewed about cherubism, emphasizing the relevant clinicoradiographic features and treatment. Literature was selected through a search of PubMed and Scielo electronic databases. The keywords used for search were adolescent, cherubism, cherubism/physiopathology, cherubism/treatment, cherubism/radiography. A manual search of the reference lists of the identified articles and the authors' article files and recent reviews was conducted to identify additional publications. Those studies that described new features about cherubism were included in this review. In total 44 literature sources were obtained and reviewed. Studies that described new features about cherubism physiopathology, diagnostics and treatment were reviewed. Despite the exceptions, cherubism is a clinically well-characterized disease. In cases of a suspicion of cherubism, radiographic examination is essential since the clinical presentation, the location and distribution of the lesions may define the diagnosis. Histopathological examination is complementary. Nowadays, genetic tests should be used for final diagnosis of cherubism.

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.

A simulation tool for transient stability analysis on vector computers

This paper deals with transient stability analysis based on time domain simulation on vector processing. This approach requires the solution of a set of differential equations in conjunction of another set of algebraic equations. The solution of the algebraic equations has presented a scalar as sequential set of tasks, and the solution of these equations, on vector computers, has required much more investigations to speedup the simulations. Therefore, the main objective of this paper has been to present methods to solve the algebraic equations using vector processing. The results, using a GRAY computer, have shown that on-line transient stability assessment is feasible.

Representation of transmission lines: comparison of models and parameters distributed discrete parameters

A transmission line is characterized by the fact that its parameters are distributed along its length. This fact makes the voltages and currents along the line to behave like waves and these are described by differential equations. In general, the differential equations mentioned are difficult to solve in the time domain, due to the convolution integral, but in the frequency domain these equations become simpler and their solutions are known. The transmission line can be represented by a cascade of π circuits. This model has the advantage of being developed directly in the time domain, but there is a need to apply numerical integration methods. In this work a comparison of the model that considers the fact that the parameters are distributed (Universal Line Model) and the fact that the parameters considered concentrated along the line (π circuit model) using the trapezoidal integration method, and Simpson's rule Runge-Kutta in a single-phase transmission line length of 100 km subjected to an operation power. © 2003-2012 IEEE.
