A revenda de combustível e os limites constitucionais para a sua regulação: uma análise aplicada aos aspectos concorrênciais e ao controle de preços

The gas retail represents the end of a section of the oil and natural gas derivative chain, for it is at this stage where the commercialization of those merchandises takes place towards the costumers. This process involves an enormous amount of economic agents, which reflects on an activity of great influence on the citizen's everyday. By the time of the gas retail price liberalization, in 2002, there were great expectations towards that measure, for the insertion of that segment in a competitive market was likely to create a decrease in prices. As there was not a drastic drop off in cost, the question was no longer the price itself, but, predominantly, the conduct taken by the economic agents that operate the market. Not in vain, the segment introduces a greater number of different procedures combined with the organs that compose the Brazilian System of Competition Protection. What is understood, however, is that many of these complaints are made in a lightly way, without a proper analysis of the market and its practices, that being why, in this paper, evidences the causes of these complaints and explained what, in fact, occurs in this market. Also, the organs that protect the free initiative in the sector use different methods to assess anticompetitive practices, which are counterproductive on the combat of anticompetitive practice, that being why the present paper analyzes the used methods on a critic perspective, choosing one which is believed to be the most adequate. The present work also tries to present the gas retail prices on a constitutional, free competition, free initiative and consumers defense perspective, analyzing the competition s aspects on the gas market; the shaping of the gas prices; the market boundaries; the anti-competitive practices under the gas market; and analyze the possibility, according to the defined economic standards in the constitutional text of existing a greater control or gas price indexing and/or regulation which limits the distributors and resellers profit on gas. Still, in consequence of this analysis, a study on Natal s market behavior will be developed in its competitive feature. That being said, moreover being a theoretical-descriptive study, data and statistics gathered is used, which will lead, willing to grasp an experiential study on a few aspects of the Potiguar gas retail market

Flutuação populacional e análise faunística de Carabidae e Staphylinidae (Coleoptera) em Jaboticabal, São Paulo

In this study a population survey of Carabidae and Staphylinidae (Coleoptera) adults was carried out with the aim to analyze their populations through faunistic indexes and to determine the influence of temperature, relative humidity and rainfall. The study was conducted in two areas cultivated with soybean/corn under no-tillage and conventional tillage systems and adjacent to a forest fragment and a Pinus stand, respectively. Beetles were sampled by pitfall traps distributed in two 100-m transects. The fauna was characterized by diversity (H), evenness (J), abundance, dominance, frequency and constancy indexes. The influence of air temperature, relative humidity and rainfall was verified using stepwise regression. The carabids Abaris basistriatus Chaudoir, Odontochila nodicornis (Dejean) and Scarites sp. were classified as predominant species in both areas, while Selenophorus alternans Dejean only classified as predominant in the area under conventional tillage system, likewise for Megacephala sp. and Selenophorus seriatoporus Putz. in the no-tillage area. The predominant species showed just one population peak each year, usually observed from December to January. The pluvial precipitation influenced the occurrence of the carabids positively and significantly, with O. nodicornis and Megacephala sp. being the most demanding species in relation to the effect of humidity on their dispersal.

Escafandristas do tempo: narrativas de vida e regeneração da memória em São Rafael-RN

In the late 1970s, the semi-arid region of Rio Grande do Norte was the setting of Projeto Baixo-Açu whose highlight was the building of the dam Eng. Armando Ribeiro Gonçalves, designed to collect 2.4 billion cubic meters of water. Presumably, such an initiative would bring economic and social development for thousands of potiguares who suffered the hardships of drought. However, the dam would reach several cities in the region, reaching to cover one of them: São Rafael. As a result, the early years of the 1980s, nearby, a new town was built by DNOCS. This thesis aims to discuss how the population of São Rafael recalls this fact and reconstructs its history by speaking, writing and computing, after three decades. Based on the prospect moriniana method as a strategy, visits were made to the city of São Rafael and open interviews (individual and collective) with two groups of subjects: one composed of those who lived in their ancient homeland, and another, with young people who were born in the new city. Besides the reports of these subjects, they were observed the visual narratives presented by images, mostly photographic, available on a profile created for the city in the orkut social network. As sources for this study, they were also considered the dialogues between rafaelenses accessing the above profile. Having as a central observation by Edgar Morin about what does not regenerate, degenerates . This study is the central argument that the idea of orkut has performed, today, a dual and interdependent role: being a tool that promotes a collective intelligence through cooperation, exchange of ideas and reconstitution of visual and written narratives. Far from a frozen conception in a historical perspective, it has defended the thesis that orkut has regenerated, repaired, reproduced, restored, reorganized and renewed the memory and history of a city that has succumbed to the immensity of the waters of a dam for almost thirty years

Os currículos praticados no cotidiano da EJA: regulações e emancipações na Escola Centro Educacional Dr. Pedro Amorim

This research has as its object of study practiced in the daily curriculum of Youth and Adults in their midst and considered discussion of the concepts of knowledge as regulation and emancipation. The camp of our research relates to the knowing / doing the teachers of this modality of education, in the Escola Centro Educacional Dr. Amorim-CEPA, the city of Assú/RN and is articulated to the emerging desire to understand how cooperating teachers have thought, organized and practiced the curriculum in order to consider the many complex situations that are present in everyday school life. Our tour was guided by the need to study the relationship between the regulated curriculum and practiced in everyday adult education, as well as to understand, from the knowing / doing of the teachers, the conceptions that guide their teaching practices and, therefore, reflect on this Reality curriculum in order to better signify then. In this sense, we turn to the fundamentals of qualitative research, adopting the procedures of documentary research, participant observation and semi-structured interview, which allowed us to enter a universe of complex dimensions, senses, and that add significant difference, because the forms of use of various practitioners are and unique, in that enroll in school life and define their brand identities. The predominance of a traditional teaching practice nature by a process of training and teaching experience, the lines of flight, volatilities and inventiveness promoted by the circumstances of everyday life are some of the conclusions we draw from the data collected. This reality, we infer that the practice of teachers varies between regulation and emancipation, being this time, many challenges to be faced, namely the process of continuing education, the conceptual understanding of the subject curriculum and the existence of relational different knowing / doing produced, used and created in/from the school routine of Youth and Adults

Contribuições à análise de robustez de sistemas de controle usando redes neurais

This work develops a robustness analysis with respect to the modeling errors, being applied to the strategies of indirect control using Artificial Neural Networks - ANN s, belong to the multilayer feedforward perceptron class with on-line training based on gradient method (backpropagation). The presented schemes are called Indirect Hybrid Control and Indirect Neural Control. They are presented two Robustness Theorems, being one for each proposed indirect control scheme, which allow the computation of the maximum steady-state control error that will occur due to the modeling error what is caused by the neural identifier, either for the closed loop configuration having a conventional controller - Indirect Hybrid Control, or for the closed loop configuration having a neural controller - Indirect Neural Control. Considering that the robustness analysis is restrict only to the steady-state plant behavior, this work also includes a stability analysis transcription that is suitable for multilayer perceptron class of ANN s trained with backpropagation algorithm, to assure the convergence and stability of the used neural systems. By other side, the boundness of the initial transient behavior is assured by the assumption that the plant is BIBO (Bounded Input, Bounded Output) stable. The Robustness Theorems were tested on the proposed indirect control strategies, while applied to regulation control of simulated examples using nonlinear plants, and its results are presented

Produção de enzimas por fungos em fermentação semi-sólida utilizando bagaço de coco e pedúnculo de caju como substratos

The production of enzymes by microorganisms using organic residues is important and it can be associated with several applications such as food and chemical industries and so on. The objective of this work is the production of CMCase, Xylanase, Avicelase and FPase enzymes by solid state fermentation (SSF) using as substrates: bagasse of coconut and dried cashew stem. The microorganisms employed are Penicillium chrysogenum and an isolated fungus from the coconut bark (Aspergillus fumigatus). Through the factorial design methodology and response surface analysis it was possible to study the influence of the humidity and pH. For Penicillium chrysogenum and the isolated fungus, the coconut bagasse was used as culture medium. In another fermentation, it was used the mixture of coconut bagasse and cashew stem. Fermentations were conducted using only the coconut bagasse as substrate in cultures with Penicillium chrysogenum fungus and the isolated one. A mixture with 50% of coconut and 50% of cashew stem was employed only for Penicillium chrysogenum fungus, the cultivation conditions were: 120 hours at 30 °C in BOD, changing humidity and pH values. In order to check the influence of the variables: humidity and pH, a 2 2 factorial experimental design was developed, and then two factors with two levels for each factor and three repetitions at the central point. The levels of the independent variables used in ascending order (-1, 0, +1), to humidity, 66%, 70.5% and 75% and pH 3, 5 and 7, respectively. The software STATISTICA TM (version 7.0, StatSoft, Inc.) was used to calculate the main effects of the variables and their interactions. The response surface methodology was used to optimize the conditions of the SSF. A chemical and a physic-chemical characterization of the coconut bagasse have determined the composition of cellulose (%) = 39.09; Hemicellulose (%) = 23.80, Total Lignin (%) = 36.22 and Pectin (%) = 1.64. To the characterization of cashew stem, the values were cellulose (g) = 15.91 Hemicellulose (%) = 16.77, Total Lignin (%) = 30.04 and Pectin (%) = 15.24. The results indicate the potential of the materials as substrate for semisolid fermentation enzyme production. The two microorganisms used are presented as good producers of cellulases. The results showed the potential of the fungus in the production of CMCase enzyme, with a maximum of 0.282 UI/mL and the Avicelase enzyme the maximum value ranged from 0.018 to 0.020 UI/ mL, using only coconut bagasse as substrate. The Penicillium chrysogenum fungus has showed the best results for CMCase = 0.294 UI/mL, FPase = 0.058 UI/mL, Avicelase = 0.010 UI/mL and Xylanase = 0.644 UI/ mL enzyme, using coconut bagasse and cashew stem as substrates. The Penicllium chrysogenum fungus showed enzymatic activities using only the coconut as substrate for CMCase = 0.233 UI/mL, FPase = 0.031 to 0.032 UI/ mL, Avicelase = 0.018 to 0.020 UI/mL and Xylanase = 0.735 UI/ mL. Thus, it can be concluded that the used organisms and substrates have offered potential for enzyme production processes in a semi-solid cultivation

Além das xícaras: a construção do Café São Luiz como lugar de memória em Natal (1950-1980)

This research stands in discussions involving the relationship between memory, history and space. We will work with the Café São Luiz in the neighborhood of Cidade Alta in Natal, an place which remains open and founded in 1953. The place was opened in the district of greater movement of the 1950s, a zone of concentration of commerce and leisure. In consequence an impulse of memory, the Café São Luiz was represented by different statements, which they built a space that serves to support memory and identity of a group. The speeches elaborate the Café São Luiz as a monument, a place of memory according to Pierre Nora. Among these discourses of construction of the Café São Luiz stands out the 1982 book titled Na Calçada do Café São Luiz by José Luiz Silva. This research aims to discuss the construction of the Café São Luiz as a place of memory, questioning their representations, traversing the authorship of speeches over the place
