The environment, which fundamental importance has already been recognized in all the world, is an actual national and international discussion subject, whose interest grows for the society, and consequently to the Law, in order to prevent the natural resources to the present and future generations. The 1988 Brazilian Constitution, recognizing the importance of the environment, treated about it in many of its parts, even dedicating a specific chapter (Chapter V About Environment, inserted in Title VIII About Social Order). The brazilian constitutional text established to everyone the fundamental right of enjoying an equilibrated environment, obligating the State and all society to defend and preserve the environment to the present and future generations. The economic growing process, that predominated and still persist in the big majority of the countries, where is practiced the capitalist system, has in the enterprises (legal persons) one of its main actors. Many times, these enterprises, especially in the actual globalized world in where we live, where the gain of money is priorized, ends, at the moment they act, making damages to the environment. These damages are, many times, considered by the law. crimes against the environment. The 1988 Brazilian Constitution, according to the Modern Criminal Law, realizing that many crimes were being committed by the enterprises, established in article 225, §3rd, the criminal responsibility of the legal persons. Almost ten years after the 1988 Brazilian Constitution, was published the Law number 9.605/98, in which third article established the penal responsibility of the legal persons that practice crimes against the environment, without excluding the individual responsibility

A pesquisa analisa as possibilidades abertas pela exploração de petróleo na camada pré-sal, avaliando de que maneira a expansão do setor petrolífero poderá acelerar o crescimento econômico brasileiro e contribuir para novas estratégias de desenvolvimento. A hipótese inicial é que o Brasil enfrenta uma restrição estrutural de balanço de pagamentos, que poderá ser amenizada pela diminuição das importações de petróleo e derivados e pelo aumento do valor exportado no setor. Para avaliá-la são resgatados aspectos históricos e geopolíticos relacionados ao petróleo, assim como são tratadas as características microeconômicas dos recursos naturais não renováveis. Também se consideram questões de ordem macroeconômica, como a especialização produtiva da economia brasileira e sua inserção no comércio internacional, discutindo como o desenvolvimento da indústria petrolífera poderá afetá-las. Para tanto, a investigação fundamenta-se na teoria estruturalista e nos modelos de crescimento com ênfase na restrição externa. O trabalho examina ainda os casos da Rússia, Venezuela e México para avaliar a experiência de países exportadores de petróleo. Como contribuição, um modelo de crescimento é utilizado para realizar simulações acerca do Brasil, cobrindo o período 2013-2020 com a formulação de três cenários. A partir dos resultados discute-se que a necessidade de consecução das metas fiscal e de inflação pode desencadear políticas restritivas que limitam a utilização da folga fiscal e externa, oriundas do pré-sal, para induzir o crescimento. Conclui-se que um círculo virtuoso de desenvolvimento com mudança estrutural depende não apenas da modernização produtiva, mas também, e principalmente, da evolução político-institucional do país

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

Buscando-se avaliar morfofisiologicamente a rebrota do capim-mombaça, quatro desfolhas foram impostas ao perfilho principal, sendo estudado o comportamento da planta em termos da taxa de expansão da área foliar, crescimento do sistema radicular, nível de carboidratos totais não estruturais (CTNE) da raiz e do colmo, taxa de crescimento relativo (TCR), taxa de assimilação líquida (TAL) e razão de área foliar (RAF) às idades de 2, 5, 9 e 16 dias após as desfolhas, bem como da taxa fotossintética máxima às idades de 2, 6 e 13 dias das folhas remanescentes à desfolha. As desfolhas foram as seguintes: remoção de todas as lâminas foliares (desfolha total), a remoção da lâmina da folha adulta mais jovem (desfolha superior), a remoção das lâminas das duas folhas adultas mais velhas (desfolha inferior) e controle (sem desfolha), juntamente com o corte dos demais perfilhos, realizado a 8 cm do solo. Foram observadas cinco repetições por tratamento, segundo o delineamento inteiramente casualizado. As folhas adultas não diferiram quanto às taxas fotossintéticas máximas, que exibiram aumento nos primeiros dias após a desfolha, e queda aos 13 dias. A desfolha reduziu os teores de CTNE da base do colmo, principalmente nas plantas sob desfolha total. Comprometimento do crescimento do sistema radicular e do teor de CTNE das raízes foi observado nas plantas sob desfolha total, que também tiveram sua TCR reduzida nos primeiros dias de rebrotação. Entretanto, o aumento na RAF possibilitou a estas plantas recuperação da TCR e alta taxa de expansão da área foliar, igualando a área foliar das demais plantas aos 16 dias de rebrota.

Este experimento foi conduzido, por um período de 100 dias, com o objetivo de estudar diferentes fontes e níveis de proteína bruta em dietas para juvenis de pacu. Foram utilizados 252 juvenis de pacu, distribuídos em 36 caixas de cimento amianto com volume de 150 litros, sendo estocados sete peixes em cada unidade. Durante o período experimental, a temperatura média da água permaneceu em 28ºC e os demais parâmetros limnológicos (oxigênio dissolvido, pH, alcalinidade e condutividade) apresentaram-se dentro dos níveis adequados para o desenvolvimento desta espécie. O delineamento experimental foi de blocos casualizados, no qual foram avaliados nove tratamentos em esquema fatorial 3 x 3, sendo três níveis de substituição da fonte protéica de origem animal (farinha de peixe), pela fonte de origem vegetal (farelo de soja), aos níveis de 0, 50 e 100% e três níveis de proteína bruta (18, 22 e 26%). Os resultados obtidos indicaram que o nível de 22% de proteína bruta foi mais adequado e a farinha de peixe pode ser substituída parcial ou totalmente pelo farelo de soja. A substituição da farinha de peixe por farelo de soja proporcionou os melhores coeficientes de digestibilidade, sem afetar ganho de peso, conversão alimentar, taxa de crescimento específico e taxa de eficiência protéica dos juvenis. Esta substituição também não afetou a composição corporal dos peixes, como a eficiência de retenção de nitrogênio, nitrogênio corporal, gordura corporal e nitrogênio e gordura no ganho de peso.

Reguladores de crescimento aplicados às plantas de algodoeiro (Gossypium hirsutum L.) podem ser lavados em função da ocorrência de chuvas. Chuvas que ocorrem próximas à época de aplicação podem ocasionar elevada perda e necessidade de reaplicação dos produtos visando à taxa de crescimento desejada. Avaliou-se o efeito do intervalo de tempo entre a ocorrência de chuva simulada e a aplicação de cloreto de mepiquat e cloreto de chlormequat no algodoeiro no crescimento das plantas, além de estimar a necessidade de reaplicação dos reguladores. Plantas de algodão foram cultivadas em vasos de 12 L que permaneceram em casa de vegetação. Os reguladores de crescimento foram aplicados 40 dias após a emergência, quando 50% das plantas apresentavam botão floral. A chuva foi simulada 1, 2, 4, 6 e 24 horas após a aplicação dos reguladores. Determinou-se a altura das plantas antes da aplicação dos produtos e a cada 3 dias até o 30º dia. Na colheita, foi avaliado o número de ramos e estruturas reprodutivas, com posterior determinação da massa da matéria seca. Também foi determinado o crescimento acumulado e taxa de crescimento das plantas. Os dois reguladores reduziram a massa da matéria seca das plantas, independente do intervalo para ocorrência da chuva. O crescimento excessivo das plantas foi controlado, porém, com eficiência reduzida quanto menor o intervalo para simulação de chuva. em todos os períodos avaliados houve perda de produtos, com necessidade de reaplicação. A taxa de reaplicação de cloreto de mepiquat para os diferentes intervalos de chuva foi, em média, 17% maior.

In recent decades, the generation of solid and liquid waste has increased substantially due to increased industrial activity that is directly linked to economic growth. For that is the most efficient process, it is inevitable generation of such wastes. In the oil industry, a major waste generated in oil exploration is produced water, which due to its complex composition and the large amount generated, has become a challenge, given the restrictions imposed by environmental laws regarding their disposal, making if necessary create alternatives for reuse or treatment in order to reduce the content of contaminants and reduce the harmful effects to the environment. This water can be present in free form or emulsified with the oil, when in the form of an emulsion of oil-water type, it is necessary to use chemicals to promote the separation and flotation is the treatment method which has proved to be more efficient, for it can remove much of the emulsified oil when compared to other methods. In this context, the object of this work was to study the individual effects and interactions of some physicochemical parameters of operations, based on previous work to a flotation cell used in the separation of synthetic emulsion oil / water in order to optimize the efficiency of the separation process through of the 24 full factorial design with center point. The response variables to evaluate the separation efficiency was the percentage of color and turbidity removal. The independent variables were: concentration of de-emulsifying, oil content in water, salinity and pH, these being fixed, minimum and maximum limits. The analysis of variance for the equation of the empirical model, was statistically significant and useful for predictive purposes the separation efficiency of the floater with R2 > 90%. The results showed that the oil content in water and the interaction between the oil content in water and salinity, showed the highest values of the estimated effects among all the factors investigated, having great and positive influence on the separation efficiency. By analyzing the response surface was determined maximum removal efficiency above 90% for both measured for turbidity as a measure of color when in a saline medium (30 g/L), the high oil concentrations (306 ppm) using low concentrations of de-emulsifying (1,1 ppm) and at pH close to neutral

Discute-se, neste texto, o significado dos 14 anos de governos Radicais que se seguiram à vitória da Frente Popular em 1938. Neste período, o Chile conseguiu combinar crescimento econômico e democracia representativa, alcançando um grau nada desprezível de modernização. Ruptura e continuidade compõem o par indissolúvel do percurso modernizador vivido a partir da Frente Popular, quando se instituiu um novo nexo entre economia, política e relações sociais. O período é caracterizado como uma modalidade específica de revolução passiva, responsável pela atualização da ordem capitalista no país.

The northeastern semiarid is a region that presents a serious picture stagnation or slowness of the economic growth, beyond the presence of social pointers below of the averages national and regional. The half-dryness conditions become the improper region for many agricultural cultures, what it affects the local populations directly, as well as the economy that is based mainly on agriculture. Cnidoscolus quercifolius Pohl, popularly know as favelone is a native species of the semiarid region that withholds great potential for the development of the region in virtue of its multiple uses. Being an oleaginous, its production in familiar farmings makes with that biodiesel either for the misery an important alternative eradication for the possibility of occupation of enormous contingents of people. The present study it aims at to evaluate the germination of the faveleira without thorns under conditions of water and saline stresses, main stresses which the vegetal species of the semiarid one are submitted; beyond verifying the acceptance of the species for agriculturists of a cooperative in the city of Apodi/RN. The methodology used for germination corresponds to using treatments with polyethylene glycol and sodium chloride to assess water and salt stress respectively, being held in rolo. O system approach used for the verification of acceptance of faveleira was the use of interview with farmers cooperative in the study area determined. In this direction it was verified that the faveleira is a resistant species the conditions of drought and salinity of the ground, factor of great relevance, since one is about a species with high added value, making possible the development for the semiarid region. It was verified that the agriculturists are favorable the introduction of the faveleira and reveal receptive the idea to cultivate a species with potential for production of biodiesel

Quilombo communities remaining are groups marked by insufficient public assistance and characterized by living in rural and conducting economic activities such as agriculture. The development on a sustainable basis is important to ensure strategies for economic growth and environmental preservation. This work aims to study the remaining Quilombo Capoeira Black community, located in the municipality of Macaíba, Rio Grande do Norte, considering the principles of sustainable development. Attempt to respond to what level such community can be considered sustainable from an analysis of their social practices. The methodological procedures used consisted of a literature review and documentary, questionnaires, conducting semi-structured interviews and direct observation. The final results show that the family farm has characteristics that approximate the principles of sustainable development, including the diversification of labor, food production with less environmental damage and strengthening the rural environment, and indicate that the main economic activities practiced in Capoeira dos Negros community are agriculture, manufacturing of cassava flour and brick manufacturing, which, in turn, are linked to negative environmental impacts, such as sedimentation pond, groundwater contamination, air pollution and soil erosion. What lead to the conclusion that the social practices of the community are not in line with the dimensions of sustainable development. It is hoped that the survey results provide subsidies for development and implementation of public policies

La recherche sur secteur non-formel de l économie et la dynamique des territoires dans les plages de la ville de Natal/RN, a le but de la compréhension des espaces de ces territoires ainsi que leurs caractéristiques; le rapport des acteurs sociaux et l existence de politiques dirigées direct ou indirectement vers ce secteur de l économie et ses territoires. Pour celà, on donne emphase au scénario économique moulé par le système de production et reproduction dans la mondialisation, ce qui, parmis d autres actions aq l inetrférence sur le marché du travail, lequel subit constamment des transformations importantes cherchant à suivre les changements en niveau global, en devenant, pour ainsi dire, un marché chaque fois plus exigeant et, conséquemment, sélectif. Moyennant la réalité économique et politique vécue, il augmente le nombre de chômeurs dans le pays suscitant, à tort et à travers, la croissance du secteur non-formel de l économie avec ses inombrables travailleurs qui occupent les plus différents segments parmi lesquels les travaux autonomes, ici représentés par les camelots, les propriétaires de baraques, les propriétaires de kiosques ; etc. Pour atteindre ce but, on a cherché les reférenciels théorico-scientifiques ayant pour base la connaissance empirique à travers les inombrables cas d études matérialisés au moyen de donnés primaires et sécondaires. Finalement, on est sûr de ce que les travailleurs du secteur non-formel complèmentent la chaîne repoductive, ils créent et recréent des territoires avec des contenus variés qui sont indispensables pour la croissance et le développement social

Objetivou-se, neste estudo, avaliar os efeitos de diferentes níveis de fibra bruta e de óleo de soja em rações para a tilápia do Nilo. Utilizaram-se 24 aquários circulares de 250 L, dotados de sistema individual de reabastecimento de água e aquecimento. A densidade de estocagem foi de sete peixes/aquário, totalizando 168 peixes, com peso inicial médio de 6,41±0,05 g. Ganho de peso, conversão alimentar aparente, taxa de crescimento específico e taxa de eficiência protéica foram avaliados. Foram analisados a composição química e o rendimento de carcaça, gordura visceral e índice hepatossomático dos peixes. O experimento foi realizado segundo um esquema fatorial 3 x 2 (três níveis de fibra bruta 6,00; 9,00 e 12,00%, com e sem óleo de soja) no delineamento inteiramente ao acaso com quatro repetições. Verificou-se que a fibra interfere de forma significativa na digestibilidade aparente da dieta, com ação positiva para a proteína e negativa para a matéria seca, não interferindo na digestibilidade do extrato etéreo; que a fibra bruta não tem efeito significativo sobre o rendimento de carcaça e no depósito de gordura visceral, mas a inclusão de óleo à ração tem efeito significativo no depósito de gordura visceral; que a fibra resulta em efeito significativo na composição química da carcaça (teor de água e proteína), não tendo efeito sobre sua composição em gordura; e que a inclusão de gordura à ração diminui e eleva de forma significativa, respectivamente, o conteúdo de proteína e extrato etéreo da carcaça. Concluiu-se que, na fase de alevinagem (6,40 a 31,00g), pode-se utilizar na dieta da tilápia do Nilo até 9,00% de fibra bruta, e que a suplementação de níveis excessivos de lipídeos na dieta piora a composição da carcaça e resulta em maior depósito de gordura visceral.
