Impacto do racionamento nos resultados das empresas concessionárias do serviço público de distribuição de energia elétrica: um estudo nas empresas privadas da Região Nordeste

This work verifies the impact caused by the Emergencial Program of Reduction of Consumption of Electric Energy (energy-rationing program) in the results of the concessionary private companies of the public service of electric energy distribution localized in the Northeast Area. As the rationing invigorated from June 2001 to February 2002, its effects are diluted in the results presented by these companies in the second semester of 2001 and first quarter of 2002, with prominence for the last quarter of 2001, when the revenue of extraordinary tariff restore was instituted by the National Agency of Electric Energy (ANEEL), consequence of the so-called General Agreement of the Electric Sector made between the federal government and the companies of the electric sector. The structure of a generic electric sector and a historical review of the Brazilian electric sector from the time it was controlled by the private enterprises, including the State control period, about 1960, and returning to the control of the private enterprises in 1990, under a new regulation structure are presented. An explanation of the models of economic regulation that Brazil used for the electric sector is made, with prominence for the price cap that is the actual effective model. The process of tariff revision foreseen in the concession contracts signed by the federal government and the concessionary companies is presented, highlighting its two stages: the tariff rebalancing that defines the new price cap and the calculation of the factor X that establishes the efficiency goals for the companies. There is made a presentation of the Emergencial Program of Reduction of Consumption of Electric Energy and of the consequent General Agreement of the Electric Sector, which created the revenue of extraordinary tariff restore. A conceptual revision on reviews is presented, regarding to concepts, accomplishment and recognition. A brief review of the six companies that made part of the worked sample is also presented. Analyzing the quarters historical review and of amount of sold energy, it was possible to conclude that the energy-rationing altered the results of the studied companies significantly and that alteration was masked by the accounting process of the revenue of extraordinary tariff restore

Proteção constitucional do consumidor no âmbito da regulação publicitária

The concern with issues related to consumer protection has emerged in North America and then spread throughout the world. In Brazil, consumer‟s rights and interests only gained greater importance after their consolidation in the Constitution of 1988 and the enactment of the 8078/90 Law (Consumer‟s Protection and Defense Code), which established the consumerist microsystem. The understanding of the legal relationship of consumption concept is necessarily connected to knowledge of the elements that compose it. Among these, we can find the consumer and the provider (subjective elements), the product or service (objective elements), and the consumer‟s condition as final receiver of the consumption object (finalistic element). In order to elucidate the configuration of consumer protection before advertising communication, this work will analyze the advertising through the prism of consumerist laws, conceptualizing it and presenting a differentiation of it in relation to practices such as marketing, offer and commercial communication as well as examining its several kinds of manifestation, focusing mainly the ones categorized as misleading or unfair advertising. All kinds of advertising communication against the consumerist microsystem are subject to judicial control exercised by the State. Besides individual protection possibilities, this state-owned control can be collectively exercised as a result of the utilization of public civil action and popular action. Some specific categories of advertising (smoking products, alcoholic beverages, pesticides, medicines and therapies) are still subject to a set of particular restraints provided by the 9294/96 Law, which enables the performance of a special control in relation to them. In addition to state control, there is also a system of advertising communication self-regulation, which develops itself through the actions of the National Council of Advertising Self-Regulation that are based mainly on the laws established by the Brazilian Code of Advertising Self-Regulation and its annexes. However, this system of advertising self-regulation still has some deficiencies that hinder its effectiveness

A educação informal para o consumo infantil e juvenil na televisão e na mídia

The consumption has become a major pillar of modern capitalism and at the same time, one of the factors that relate to social inequality. Karl Marx developed the theory of historical materialism which maintains a history of society determined by class struggle and the! exploitation of man by man. Considered to be overtaken by those who believe that Marxism is synonymous with real socialism, the Marxist ideals seem more present than in the Western world which each individual takes the individualization (loss of sense of public and collective) and the alienation by the work. Weassumed we could work on these issues in student education, even in elementary school, through questioning of the consumer society, with the criticism of television and the media, the main promoter of the current sense of consumption, as an initial step that could lead to future autonomy of theindividual. The theory of ideology and ideas of Paulo Freire's liberating education theory permeated the experience that happened as a participant observation of groups in the discipline of sociology in the unit 2 of the Colégio Pedro II in Rio de Janeiro, the state capital, an institution under the direct administration Ministry of Education. Wehave found fertile ground in which the students were able to understand and question the meaning of advertising media

Mapa dos programas sociais: transferência de renda e dinâmicas sociais no Rio Grande do Norte (2000-2007)

The question of evaluating the fight against poverty in a given society is very complex task, considering the range of factors that permeate, such as education, culture and economy itself. Come hence the relevance of the theme and its constant presence in discussions on the fruits of public policies, institutional structure and economic development which are the guiding elements of this work, and noted that seeks to highlight the social demographics and most important, the most significant trends and issues pertaining to her. The assessment was initially made in all the municipalities of Rio Grande do Norte doing a verticalilzação to the municipalities Caicó, Pau dos Ferros, Ipueira and Taboleiro Grande. Highlighting the role of a social policy through government programs, such as the Bolsa Familia Program (PBF), which creates the possibility of changes in the socio demographic profile given the importance that the action of this public policy has in shaping the regional economic reality As well as social programs and actions of the government here reported that generate mobility of people and new social demands, such as rural retirements, the benefit of continuing provision (BPC), the Program for the Eradication of Child Labor (PETI) that put on the market of population living on the margins of various forms of consumption. Accordingly, the socio economic profile of the state shows a significant improvement in their social indicators, vital education and redistribution of income, due to the significant improvement in life expectancy in the fall of school drop-out rate and the drop in indicators of Proportion Poor and destitute of the state. Where the fall in the proportion of poor and indigent is strongly associated with an increase in income, from social programs. With this transfer and redistribution of income can be gauged that occurs a strengthening of local economies and an engagement of families with the conditionalities of social programs and PETI Bolsa Familia. Our research concludes that simply raising the rents caused by transfers, presents relevant impacts on the education of young people in beneficiary families. There is no doubt that the programs of transfer income, no facing the social field, representing a mechanism to decrease the most perverse ills of poverty, social and economic inequality that is hungry. For a significant portion of the Brazilian population living below the poverty line, programs for the transfer of income are expressed directly in improving the material conditions of life and indirectly in improving self-esteem of women and all family members receiving encouraging yet the integration family. Experiments have shown that improvements in health and nutrition can be obtained through the implementation of adequate social policies like the programs of transfer income, while social inclusion and economic does not become full

Consumo privado de ansiolíticos benzodiazepínicos e sua correlação com indicadores sociodemográficos nas capitais brasileiras

This work aims to analyze the distribution of anxiolytics and their frequency of consumption in the period of 2010 to 2012, on the Federal District and at other Brazilian cities, as well as evaluating the correlation between such consumption and its demographic, epidemiological, economic and social characteristics for each region of this study. Into the analysis, it was observed that social, economic and cultural factors seem to influence the over-consumption of these drugs in many countries. Based on this, the benzodiazepines (BDZs) have achieved great popularity among members of the medical community and among the general population, mainly because of its safety and effectiveness in controlling symptoms of anxiety, insomnia and convulsions. Concerning the methodology of this work, an ecological study was performed having as sampling Brazilian capitals and as data source the 2010 Population Census, as well as information from IBGE, DATASUS and ANVISA. Still in the case of the methodological procedure, a multiple linear regression was used. Through descriptive analysis, it was demonstrated that the Northern region has the lowest average on consumption of these drugs (being 0.24 DHD in Manaus); meanwhile in the capitals of the Southeast, higher means were identified (reaching 7.29 DHD in Belo Horizonte), with a national average of 3.04 DHD. Among the drugs analyzed, it was found that Alprazolam is the most dispensed by pharmacies and private drugstores, averaging 2.00 DHD for Brazilian capitals. A análise de regressão linear múltipla mostrou que 76% da variação no consumo foi explicada pela variação da densidade populacional (β = 0,310 p = 0,045) e pela percentagem de médicos (β = 0,507 p = 0,016). Therefore, it was concluded that the consumption of anxiolytics of short half-life has been increasing over the years, mainly in the cities of greater population density and with the highest concentration of doctors

Avaliação dos efeitos da retirada do etanol em curto e longo prazo sobre respostas comportamentais relacionadas à ansiedade e sobre células imunorreativas para a serotonina no núcleo dorsal da Rafe em ratas

Ethanol withdrawn individuals present a wealth of signs and symptoms, some of them related with anxiety. To better understand brain areas involved in anxiety caused by ethanol abstinence, preclinical studies have been employing models of ethanol consumption followed by withdrawal in rodents submitted to behavioral tests of anxiety, such as the elevated plus-maze. The aim of this study was to investigate if short- or long-term ethanol withdrawal could alter both anxiety-related behaviors in the elevated plus-maze (EPM) and open field tests and the number of serotonin immunorreactive cels in the dorsal raphe nucleus, a midbrain area associated with anxiety. Female Wistar rats (90 days old) were submitted to increasing concentrations of ethanol (2% for 3 days, 4% for 3 days and 6% for 15 days) as the only source of liquid diet and the control group received water ad libitum. Both groups received food ad libitum. In the behavioral experiments, on 21st day of consumption, ethanol was substituted by water (withdrawal) and 72 h or 21 days after withdrawal animals were submitted to the EPM, where it was evaluated the percentage of time and entries in the open arms and the entries in the enclosed arms during 5 minutes. Twenty and four hours after testing in the EPM, animals were submitted to the open field test for 15 minutes, where the distance traveled by the animals was observed along this period. During the first 5 minutes, the distance traveled, entries and time spent in the center of the test were analyzed. In the immunohistochemistry study, animals were submitted to 21 days of consumption of ethanol followed or not by 72 hours and 21 days of withdrawal previously perfusion, brain tissue preparation and quantification of serotonin dyed cells in the dorsal and caudal portions in the dorsal raphe nucleus. Behavioral data showed that both short- and long-term ethanol withdrawals reduced the open arms exploration in the EPM. In the open field test there were no locomotor activity changes during the total 15 minutes; however, longterm ethanol withdrawal reduced the exploration in the center of the open field during the first 5 minutes. In the immunohistochemistry step, there were no differences, when short- and long-term withdrawn groups were compared with control group; nevertheless, the chronic consumption of ethanol decreased the number of serotonergic immunorreactive cells in the dorsal part of dorsal raphe nucleus. Taken together, results here obtained suggest that both short- and long-term ethanol withdrawals promoted an anxiogenic-like effect that was not related with changes in the serotonin immunorreactivity in the dorsal and caudal parts of the dorsal raphe nucleus.

Análise experimental de danos em pistões de motor à gasolina operando com adição de gás hidróxi

The addition of hydrogen gas as an alternative fuel source has been widely used, as well reported in scientific literature. Today, several experiments are underway for the use of hydrogen generators (electrolysers) demand for motor vehicles. In all these products their ads manufacturers claim that this provides a reduction of fuel consumption, reduces the emission levels of toxic gas by the discharge and improves engine life. This research analyzes the physical structure of engine components using electrolysis on demand. To this end, a stationary system was fitted with a power generator of electricity, drum roller and adapted two electrolyzers: a dry cell and wet cell other. In steps observation were consumption analyzes in four work load ranges and observing the piston engine, which has been cut and analyzed by Optical Microscopy (OM), Scanning Electron Microscopy and Dispersive Energy (SEM-EDS), X – Ray Diffraction (XRD) and Confocal Microscopy, the stationary system in each step. The results showed a considerable reduction in fuel consumption and a high corrosion in the original factory piston constituted of aluminum-silicon alloy. As corrosion barrier was made a plasma nitriding in the piston head, which proved resistant to attack by hydrogen, although it has presented evidence also, of having been attacked. It is concluded that the automotive electrolysers can be a good choice in terms of consumption and reducing toxic gas emissions, but the material of the combustion chambers of vehicles must be prepared for this purpose.

Revestimento decorativo monocamada pigmentado, com resíduo de vidro temperado, para aplicação em fachadas

Although efficient from a technical point of view, mortar layers that make up the traditional masonry coating (slurry mortar, plaster and plaster) have to be in contradiction with the new construction technologies and more efficient methods of consumption and work rationalization. From an environmental point of view, the recovery of waste into new composites for the building has been a growing strand of studies in the scientific community, may prove to be a cost-effective solution in some cases. Thus, this research proposes the development of a mortar Decorative Coating Monolayer (RDM), for use in facades, produced on site, incorporating tempered glass waste (RVT) in the cement matrix, as a partial substitute for aggregate. Therefore, we adopted the binder respect / aggregate of 1: 6 (by volume), consistency index 250mm ± 20, sand substitution levels of glass waste 20%, 50% and 80% and relative water / cement varied in many traits. Two additives were used, a polymer, styrene-butadiene-based, and other chemical, besides mineral and silica fume inorganic pigment in colors red, yellow and blue. Mechanical tests were carried out on fresh pasta and hardened, as well as for the applied coating on masonry, so as to demonstrate the feasibility of the material. In addition, it verified the adequacy of the RDM built environment by means of thermal tests. The results demonstrated the feasibility of the proposed RDM with significantly higher values when compared to norms, especially the dash-added replacement content of 20% and addition of pigment in red. Therefore, the study shows the scientific community as an incentive to the use of technological innovations in construction, increasing the range of alternatives available for housing production, with the proposition of a material that achieves the desired functionality and obtain environmental gain, and may be adopted on construction sites as an alternative industrialized mortars.

"Aqui se faz Gostoso”: uma etnografia do turismo em São Miguel do Gostoso (RN)

This study it is an ethnography on the process of the tourist coast area of São Miguel do Gostoso, whose origin is made from a village of traditional fishermen located on the northeast coast of Rio Grande do Norte. From the late 90s, there were the first initiatives that transformed São Miguel do Gostoso in one of the state's major tourist destinations. The municipality is promoted within the national and international tourism scene through the sun and beach tourism - whose object of consumption is the natural landscape - and sports tourism - which exploited element is the "natural" geographic location (in the continent curve) of municipality that provides winds considered ideal for the practice of “Kitesurfing “ and Windsurfing. From this context, this ethnography had as a theme the social changes promoted by the tourism process in place here addressed, taking into account the perceptions produced by the actors involved in this social net. In this qualitative research, I endeavored to me in the methodological use of ethnographic techniques - bibliographic and field research, participant observation, open and structured interviews recorded by recording and field notes and photographic record. I also made use of theoretical tools and methodology inherent in ciberetnografia when analyzing the blogs and websites of intermediaries and institutions linked to local tourism.

Avaliação da concentração de retinol em fígados frescos e congelados de frangos das linhagens Cobb e Ross

The intake of adequate quantities of food, including those rich in vitamins, is necessary for a healthy life. The lack of vitamin A has been characterized as a public health problem in developing countries, however, a high intake of vitamin A can result in toxic and teratogenics effects. High concentrations of vitamin A have been observed in the livers of animals. The objective of this study was to assess the levels of retinol in chicken livers and verify the effect of frozen storage on these levels. 64 livers from two chicken strains, Cobb and Ross, were used, came from four different farms. We examined 32 livers from each strain, 8 samples from each farm. Liver sample were homogenized individually, then 4 aliquots were taken from each sample. One of aliquots was analyzed immediately after slaughter (T0), the others were analyzed after 30, 60 and 90 days of storage at -18oC (T30, T60 and T90, respectively). Retinol dosage in the liver was determined by High Performance Liquid Chromatography (HPLC). The levels of retinol varied significantly according to the strain. The mean retinol value in the fresh samples was 6678.0 ± 1337.7 and 8324.1 ± 1158.5 µg/100g in the Cobb and Ross strain, respectively. Values of 4258 ± 918.7 ± 1391.7 and 4650.5 ± 1391.7 μg/100g were found after 90 days of storage for Cobb and Ross strain, respectively. The liver freezing caused a significant reduction in their levels of retinol, causing a loss of up to 44% with respect to fresh livers. The reduction in retinol levels occurred from 30 days of storage. Even with the losses from the frozen, the ingestion of a typical portion of 100 g of liver, regardless the chicken strain analyzed, surpass all recommendations of consumption and the maximum tolerable intake of vitamin A (3000 μg/day) for adults
