Qualidade na educação infantil em instituições brasileiras: contributos de pesquisas acadêmicas para o debate

This article presents elements that make up the quality of education in the age group of zero to five years, offered by institutions of Early Childhood Education in Brazil, based on research results disseminated in theses and dissertations that focus on this theme. It was used as the methodological procedure outlined mapping Brazilian literature of academic research related to the Post-Graduate Education, which focus on the issue in the period between 1996 and 2012. The results of the study provide insights on funding, teacher training, family, quality of care in the school systems, institutional assessment, perceptions of quality and educational practices that allow discuss the quality of early childhood education offered in Brazilian institutions. Moreover, considering that not convenient to take the concept of quality of early childhood education as universal as this is linked to the context, the conceptions about children and their education.

Arquivo e literatura: perspectivas de acesso e difusão da memória literária no Brasil

Besides storing, the culture and science institutions in charge of the of Brazilian writers’ personal archives play such an important role on the organization and representation of the country’s literary information. In general, the target public for these collections is composed by researchers from the field of Literature once the documents produced by the writers throughout his/her life and career constitute primary research source for the artistic, historical and literary investigation. However, it is still convenient to stand out those users with no academic instruction, whose interest in such collections is justified by their looking up to the individual. In this sense, literary memory places, such as the Brazilian Literature Archive Museum – AMLB (RJ) -, the Brazilian Literature Academy – ABL – (RJ) and the Brazilian Studies Institute – IEB – (SP) turn out to be responsible for offering access to the literary archives and literary information. Thus, it is necessary to consider that databases demonstrate themselves as utter disseminators of the preservation and diffusion of the literary memory, coming up with several possibilities for cultural and scientific action in Literature. This study focuses on showing the contributions of databases towards the literary archives, the challenges and perspectives observed according to the mentioned institutions’ reality, in whose missions the discourse of the literary memory preservation is inserted.

A mixed-integer quadratically-constrained programming model for the distribution system expansion planning

This paper presents a mixed-integer quadratically-constrained programming (MIQCP) model to solve the distribution system expansion planning (DSEP) problem. The DSEP model considers the construction/reinforcement of substations, the construction/reconductoring of circuits, the allocation of fixed capacitors banks and the radial topology modification. As the DSEP problem is a very complex mixed-integer non-linear programming problem, it is convenient to reformulate it like a MIQCP problem; it is demonstrated that the proposed formulation represents the steady-state operation of a radial distribution system. The proposed MIQCP model is a convex formulation, which allows to find the optimal solution using optimization solvers. Test systems of 23 and 54 nodes and one real distribution system of 136 nodes were used to show the efficiency of the proposed model in comparison with other DSEP models available in the specialized literature.

INTEGRAL FUNCTIONALS ON C*-ALGEBRA OF VECTOR-VALUED REGULATED FUNCTIONS

In this paper we deal with the notion of regulated functions with values in a C*-algebra A and present examples using a special bi-dimensional C*-algebra of triangular matrices. We consider the Dushnik integral for these functions and shows that a convenient choice of the integrator function produces an integral homomorphism on the C*-algebra of all regulated functions ([a, b], A). Finally we construct a family of linear integral functionals on this C*-algebra.

Estudo dos parâmetros físicos na fluidização em um leito gás sólido

Through measurements of basic parameters for determining the fluidization regime, as particle size, minimum fluidization velocity, bed porosity, etc., This paper analyze the mass distribution of the phases of the bed to be discussed in relation to: the flow gas physical properties of the solid particles and the forces acting on the solid particles circulating within the bed, as the weight force, buoyancy and drag forces (Stokes' Law). Due to the weight force is constant, open up the discussion about which of the other two forces, buoyancy and drag force, influencing the behavior of the bed. We used the photographic method to realize the statistical analyzes. Therefore, we can conclude what changes can be made more convenient in fluidizing the bed to obtain the highest efficiency for a good mixing used in industrial processes

Diagnóstico dos resíduos gerados nas oficinas mecânicas de veículos automotivos do município de São Carlos-SP

The mechanical garages do varied types to activities related to the reparation from vehicles such as change from Motor oil, change and cleaning from car pieces, motor rectification, among others. These activities generate different kinds of waste and wastewater that when disposed in an inappropriate way can pollute the environmentand cause risks to the public health. Despite the environmental issues that involves these enterprises, they aren´t object of environmental licensing and there are any rules that regularizes their activities with the goal of these possible environmental impacts mitigation. The environmental diagnosis proposed by the present work has as goal the knowledge of the possible environmental aspects and their effects in the environment, for establishing control measures and from that to generate subsidy for environmental normatization of the sector in the municipal level. Furthermore, it should also define practices as waste production reduction, separation of them at the generator source and convenient final disposal, as well as wastewater production reduction and treatment of them before its launching in the wastewater network. The environmental diagnosis was based on a survey realized in garages from the city of São Carlos – SP, in order to define the more important characteristics of this activity that are related to the environment and public health. From the obtained information from the survey and the interpretation of the data, subsidy for the municipal environment management of the mechanical garages were generated.

Potenciais singulares na equação de Schrodinger unidimensional via transformada de Laplace

The present work has as its goal to treat well known and interesting unidimensional cases from quantum mechanics through an unusual approach within this eld of physics. The operational method of Laplace transform, in spite of its use by Erwin Schrödinger in 1926 when treating the radial equation for the hydrogen atom, turned out to be forgotten for decades. However, the method has gained attention again for its use as a powerful tool from mathematical physics applied to the quantum mechanics, appearing in recent works. The method is specially suitable to the approach of cases where we have potential functions with even parity, because this implies in eigenfunctions with de ned parity, and since the domain of this transform ranges from 0 to ∞, it su ces that we nd the eigenfunction in the positive semi axis and, with the boundary conditions imposed over the eigenfunction at the origin plus the continuity (discontinuity) of the eigenfunction and its derivative, we make the odd, even or both parity extensions so we can get the eigenfunction along all the axis. Factoring the eigenfunction behavior at in nity and origin, we take the due care with the points that might bring us problems in the later steps of the solving process, thus we can manipulate the Schrödinger's Equation regardless of time, so that way we make it convenient to the application of Laplace transform. The Chapter 3 shows the methodology that must be followed in order to search for the solutions to each problem

Avaliação da qualidade de óleos de fritura utilizados em restaurante universitário

Frying is a widely used method of preparing food, because it is a very fast and convenient process, and because it provides specific characteristics of color, flavor, odor, and texture, besides having great consumer acceptance. Therefore, the interest in the physiological effects that oils heated at high temperatures can cause to the human body arises. The aim of this work was to analyze the levels of frying used oil alteration in different kinds of foods served at the university restaurant at “Instituto de Biociências, Letras e Ciências Exatas” (IBILCE), in São José do Rio Preto-SP. In addition, it aims to make the restaurant aware of the good ways to fry and the commitment of providing good quality food to students and professionals of the Institute. With this purpose, determination of total polar compounds, conjugated dienoic acids, peroxide value, and fatty acid profile were analyzed. Two rapid tests were also used: 3M Fat Monitor and Oil Test kit. The results were compared with limits recommended for the disposal of oils and fats used in frying by the Brazilian Health Surveillance Agency (ANVISA), by other countries, and by other researches. Thus, it was concluded that the university restaurant provides the consumers with fried food of good quality, since none of the analyses showed results above recommended, although there is a need of improvement in the quality control of the oil used, in order to avoid unnecessary costs to the university restaurant.

Fields of two power conductor

The goal of this work is find a description for fields of two power conductor. By the Kronecker-Weber theorem, these amounts to find the subfields of cyclotomic field $\mathbb{Q}(\xi_{2^r})$, where $\xi_{2^r}$ is a $2^r$-th primitive root of unit and $r$ a positive integer. In this case, the cyclotomic extension isn't cyclic, however its Galois group is generated by two elements and the subfield can be expressed by $\mathbb{Q}(\theta)$ for a $\theta\in\mathbb{Q}(\xi_{2^r})$ convenient.

Orçamento participativo e instituições participativas: aspectos para a avaliação de experiências e casos

This article is to discuss the evaluative perspectives from which it is possible and convenient evaluate the Participatory Budgets (PBs) and the participatory institutions (PIs) that are being experienced in Brazil since the last two decades of the last century. It is proposed an integrated perspective of evaluation of PBs and PIs, in order to avoid partial and biased conclusions, especially those which are based solely or primarily on quantitative methodologies. This discussion is necessary since, in the past five years, the criticism of these experiments has been increasing. Through critical and creative reflection, in essay form, and based on the recent literature on the topic, it is concluded by the need to adopt, in the empirical evaluation, an integrated approach of evaluation of the PBs and the PIs, such as it is proposed in this article. It is conclude also which is fundamental for the theoretical advancement on the subject dedicate special attention to the desirability or not of adopting the criterion of popular participation in government decisions under representative democracy, since it is refuted by public choice and defended by neo-republicanism.

Conhecimento de mães sobre os procedimentos de emergência nos casos de avulsão dentária

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.
