Praia de Ponta Negra: uma abordagem da paisagem costeira de 1970 a 2010, Natal/RN

With process urbanization process the Brazilian cities have been goin through, Natal/RN does not differ from the other ones, it has had a fast, inordinate and planned urbanization, but not applied, it has caused a high increase of social environmental problems. One of the worrying problems observed is the change in the coastal landscape, which has caused serious damage to the city‟s population, more specifically, of Ponta Negra beach neighborhood. For the geographical studies, the issue, concerning the occupation of the beaches that has been getting higher and higher in the last decades is extremely important because these, in addition to being used as homes in the new urban configuration, have incorporated new ways of environmental interference, without a simultaneous advance of knowledge which would be necessary for a more suitable and rational use of litoral spaces. Thus, the current assignment aimed to focus the coastal landscape of Ponta Negra Beach, in the city of Natal/RN, checking and analyzing the effects caused by anthropic and natural action, and the way it reflects in the quality of life of the resident, working population and of the frequenters as well as the landscape transformations in the area which is object of study, from 1970 through 2010. The methodology used followed to stages, the first concerned the theoretical work bibliographic surveying and composition; and second one the empirical work marking of the environmental characterization and application of the questionnaires. So, we can measure that Ponta Negra, is very susceptible to environmental changes, the ones caused by the natural dynamics of the beach, as well as the human actions (society) in this really fragile and mutable space, so it needs, a more profound systematic study about the coastal landscape. In order to reach a minimization of the change of the landscapes in the coastal zones there must be an integrated management of the environments, based on the planning of actions and territorial reordination of the occupations of these so important spaces, environmentally, as well as socioeconomically. Whereas, only this way, we will have a sustentable development and a suitable use of that space

Ilha de Santana e Alto de Santa Rita: a produção do espaço a partir do turismo em Caicó e Santa Cruz - RN

Tourism is an activity that uses the spatial objects and also produces and because it creates an economic activity areas for leisure. So for this to occur itdoes need a space reorganized, with infrastructure to receive visitors. And in the process of construction / reconstruction of tourist destination the state comes as a precursor, creating public policies that tourism can develop. Thus, this paper examines the transformation process by which the spaces are aiming to become tourist, and what changes occur in socio-spatial dynamic of the city in which this activity is inserted. The spatial area of study refers to the Alto de Santa Rita, Santa Cruz and the Isla de Santana Tourist Complex in Caicó both in Rio Grande do Norte. The reconstruction of the Island de Santana did not occur randomly, in order that the spatial changes were performed to meet the demand for which Caicó had to perform his greatest social and religious event, the Feast of Santana, which occurs since its colonization in year 1748 and also the Carnival these two events being considered as a strong tourist attraction of the city. And the Santa Rita High was built in order to enter the city of Santa Cruz in the script of religious tourism of the state through the devotion of the patron. The Dissertation isstructured in five parts, the first refers to the introduction of the work, while the second examines how tourism wound to the Rio Grande do Norte and internalizesthe third part deals with the spaces for tourism in these cities, the the fourthidentifies as the symbolism of these spaces influence the transformation and the latter reveals how these spaces affect the socio-economic structure of cities across the events

Semantic categories in the indigenous languages of Brazil

This article investigates which semantic categories, as defined in Functional Discourse Grammar, formally manifest themselves in a sample of native languages of Brazil, and the extent to which the distribution of these manifestations across categories can be described systematically in terms of implicational hierarchies. The areas subjected to investigation are basic interrogative words, basic demonstrative words, and nominalization strategies.

O cangaço em “Fogo morto” e em “Os Desvalidos”

O presente estudo visa a estabelecer uma análise comparativa entre dois romances da literatura brasileira do século XX, no que tange à abordagem realizada pelas obras do fenômeno histórico-social do cangaço. As obras escolhidas, Fogo Morto, de José Lins do Rego, e Os Desvalidos, de Francisco Dantas, representam dois momentos distintos da produção ficcional nordestina. A primeira está inserida na corrente ficcional das décadas de 30 e 40. Décimo romance do escritor paraibano, Fogo Morto representa o cangaço na perspectiva do personagem José Amaro, seleiro que se transforma em ajudante do cangaceiro Antônio Silvino. A segunda obra, publicada em 1993, representa uma retomada da ficção regionalista. O romance focaliza o cangaço sob o ponto de vista de Coriolano, personagem que, ao contrário de José Amaro, demonstra ódio implacável pelo cangaço, no romance representado por Lampião. A análise comparativa das obras foi precedida pelo estudo das raízes históricas do cangaço, bem como a caracterização do cangaceiro como ser carregado de dubiedade no imaginário popular nordestino. Com efeito, o cangaceiro ora é representado como herói, ora é encarado como bandido pelo sertanejo, sendo que essa visão contraditória é transportada para a ficção, aparecendo nos dois romances que são analisados neste trabalho. A abordagem histórica do cangaço é realizada a partir de estudos de autores como Rui Facó (1983), Maria Isaura Pereira de Queiroz (1977) e Luiz Bernardo Pericás (2010). Também foi imprescindível um breve estudo de Câmara Cascudo (2005), que auxilia a compreender a figura do cangaceiro enquanto herói popular regional. Finalmente, como suporte para o estudo comparativo entre Fogo Morto e Os Desvalidos foram utilizados trabalhos de autores como José Paulo Paes (1995) e Sônia Lúcia Ramalho de Farias (2006), que fornecem elementos importantes para o estabelecimento de relações entre obras de cunho regionalista, produzidas por escritores nordestinos.

Produzione di bioidrogeno in dark fermentation da scarti dell'industria agroalimentale mediante l'impiego di batteri ipertermofili

La presente tesi di dottorato ha come argomento la produzione d’idrogeno per via fermentativa sfruttando il metabolismo anaerobico di particolari batteri estremofili del genere Thermotoga. In questo lavoro, svolto in seno al progetto Bio-Hydro, sfruttando reattori batch da 116 mL, è stato selezionato il ceppo migliore di Thermotoga fra i quatto ceppi testati: T. neapolitana. Una volta individuato il candidato batterico migliore è stato individuato il valore ottimale di pH (8.5 a t.amb) per la produzione d’idrogeno. Un intenso lavoro è stato svolto sul medium di coltura permettendone la minimizzazione e rendendolo così economicamente sostenibile per il suo utilizzo nel reattore da 19L; in questo caso il glucosio è stato completamente sostituito con due sottoprodotti agroindustriali individuati in precedenza, il melasso di barbabietola e il siero di latte. Sono stati poi eliminati i gravosi micronutrienti e le vitamine. È stata sfruttata la capacità di T. neapolitana di produrre biofilm e sono stati testati 4 diversi supporti in vetro sinterizzato e ceramici, tali test hanno permesso di individuare Biomax come supporto migliore. Sono stati svolti studi sul metabolismo di T. neapolitana volti ad individuare le concentrazioni inibenti di ogni substrato testato, l’inibizione da prodotto (idrogeno) e l’inibizione da ossigeno. Tutte queste prove hanno dato le conoscenze di base per la conduzione di esperienze su reattore da 19L. L’innovativo reattore di tipo SPCSTR è stato interamente studiato, progettato e costruito presso il DICMA. dell’Università di Bologna. La conduzione di esperienze batch su SPCSTR ha dato la possibilità di verificare il funzionamento del nuovo tipo d’impianto. Presso il Wageningen UR (NL), è stata svolta la selezione del miglior ceppo di Caldicellulosisruptor fra 3 testati e del miglior supporto per la produzione d’idrogeno; è stato poi costruito testato e condotto in continuo l’innovativo reattore CMTB.

Aplicação da destilação simulada por cromatografia gasosa e da termogravimetria para a avaliação da influência da redução do teor de enxofre sobre as propriedades físico-químicas do óleo diesel

One of the main problems related to the use of diesel as fuel is the presence of sulfur (S) which causes environmental pollution and corrosion of engines. In order to minimize the consequences of the release of this pollutant, Brazilian law established maximum sulfur content that diesel fuel may have. To meet these requirements, diesel with a maximum sulfur concentration equal to 10 mg/kg (S10) has been widely marketed in the country. However, the reduction of sulfur can lead to changes in the physicochemical properties of the fuel, which are essential for the performance of road vehicles. This work aims to identify the main changes in the physicochemical properties of diesel fuel and how they are related to reduction of sulfur content. Samples of diesel types S10, S500 and S1800 were tested according with the methods of the American Society for Testing and Materials (ASTM). The fuels were also characterized by thermogravimetric analysis (TG) and subjected to physical distillation (ASTM D86) and simulated distillation gas chromatography (ASTM D2887). The results showed that the reduction of sulfur turned the fuel lighter and fluid, allowing a greater applicability to low temperature environments and safer for transportation and storage. Through the simulated distillation data was observed that decreasing sulfur content resulted in higher initial boiling point temperatures and the decreasing of the boiling temperature of the medium and heavy fractions. Thermogravimetric analysis showed a loss event mass attributed to volatilization or distillation of light and medium hydrocarbons. Based on these data, the kinetic behavior of the samples was investigated and it was observed that the activation energies (Ea) did not show significant changes throughout conversion. Considering the average of these energies, the S1800 had the highest Ea during the conversion and the S10 the lowest values

Avaliação do controle da diagênese na qualidade de reservatório siliciclástico do cenomaniano superior da formação Açu, sudoeste da bacia potiguar

The distribution of diagenetic alterations in Late Cenomanian siliciclastic reservoirs from Potiguar Basin was influenced by the stratigraphic framework and the depositional system. Seismic sections and geophysical logs of two wells drilled in the SW portion of the mentioned basin above register regional stratigraphic surfaces representing maximum floods related to a transgressive event. The sequential analysis of 80 m of drill core (~450 m deep) recognized nine depositional facies with an upwards granodecrescent standard piling that limits cycles with an erosional conglomeratic base (lag) overlain by intercalations of medium to very fine sandstones showing cross bedding (channel, planar and low angled) and horizontal bedding (plane-parallel , wave and flaser). The top of the cycles is marked by the deposition of pelites and the development of paleosoils and lagoons. The correlation of genetically related facies reveals associations of channel fillings, crevasse, and flood plains deposited in a transgressive system. Detailed descriptions of seventy nine thin sections aided by MEV-EBSD/EDS, DRX and stable isotope analyses in sandstones revealed an arcosian composition and complex textural arrays with abundant smectite fringes continuously covering primary components, mechanically infiltrated cuticles and moldic and intragrain pores. K-feldspar epitaxial overgrowth covers microcline and orthoclase grains before any other phase. Abundant pseudomatrix due to the compactation of mud intraclasts concentrate along the stratification planes, locally replaced by macrocristalline calcite and microcrystalline and framboidal pyrite. Kaolinite (booklets and vermicular), microcrystalline smectite, microcrystalline titanium minerals and pyrite replace the primary components. The intergrain porosity prevails over the moldic, intragrain and contraction porosities. The pores are poorly connected due to the presence of intergranular smectite, k-feldspar overgrowth, infiltrated mud and pseudomatrix. The sandstones were subjected to eodiagenetic conditions next to the surface and shallow burial mesodiagenetic conditions. The diagenetic alterations reduced the porosity and the permeability mainly due to the precipitation of smectite fringes, compactation of mud intraclasts onto the pseudomatrix and cementing by poikilotopic calcite characterizing different reservoir petrofacies. These diagenetic products acted as barriers and detours to the flow of fluids thus reducing the quality of the reservoir.

Turismo rural no Rio Grande do Norte: desafios e perspectivas

The Rural Tourism appears as an economic alternative to the agricultural way, having to base itself on the revaluation of the local resources, as well as must be implemented through the local agents, a tourism of communitarian base. In this perspective the present objective work to analyze of that it forms if configures the tourist activity in the agricultural space of the Rio Grande do Norte, which the challenges and perspectives faced for the development of this activity. On the basis of this approach searched to argue on the deep transformations that the rural space comes suffering, with insertions of activities not-agriculturists, alternative for the effect of the economic reorganization, as well as on the public politics come back toward the Rural Tourism and an analysis concerning the activities of Rural Tourism that the Rio Grande do Norte comes developing and as this if it presents. As it arrives in port theoretical, we use the Concept of Territory, according to Saints, this if it makes pertinent in the conflicting analyses of the agricultural space for inside to embody of its conceptual picture the territorial dynamics substantiated by the relations politics, economic, social and cultural, where in them it made possible one better analysis in this process. As methodology bibliographical survey was used, in periodic, digital books, documents and interviews in some governmental spheres. The Great River of the North was evidenced that, signals for the development of the agricultural Tourism, therefore the state if presents with a gamma of potentialities, identified and developed some already being through some projects, however if it makes necessary a bigger involvement of all the spheres, considered basic so that this activity can be consolidated as plus a tourist segment in the RN.

Ação pública na formação e transformação do destino turístico de Porto de Galinhas: um estudo dos referenciais no período de 1970 a 2010

The central interest of this thesis is to comprehend how the public action impels the formation and transformation of the tourist destinies. The research was based on the premise that the public actions are the result of the mediation process of state and non-state actors considered important in a section, which interact aiming for prevailing their interests and world visions above the others. The case of Porto de Galinhas beach, in Pernambuco, locus of the investigation of this thesis, allowed the analysis of a multiplicity of actors on the formation and implementation of local actions toward the development of the tourism between the years 1970 and 2010, as well as permitted the comprehension of the construction of the referential on the interventions made. This thesis, of a qualitative nature, has as theoretical support the cognitive approach of analysis of the public policies developed in France, and it has as main exponents the authors Bruno Jobert and Pierre Muller. This choice was made by the emphasis on the cognitive and normative factors of the politics, which aspects are not very explored in the studies of public policies in Brazil. As the source of the data collection, documental, bibliographic and field researches were utilized to the (re)constitution of the formation and transformation in the site concerned. The analysis techniques applied were the content and the documental analysis. To trace the public action referential, it started by the characterization of the touristic section frontiers and the creation of images by the main international body: the World Tourism Organization, of which analysis of the minutes of the meetings underscored guidelines to the member countries, including Brazil, which compounds the global-sectorial reference of the section. As from the analysis of the evolution of the tourism in the country, was identified that public policies in Brazil passed by transformations in their organization over the years, indicating changes in the referential that guided the interventions. These guidelines and transformations were identified in the construction of the tourist destination of Porto de Galinhas, of which data was systematized and presented in four historical periods, in which were discussed the values, the standard, the algorithms, the images and the important mediators. It has been revealed that the State worked in different roles in the decades analyzed in local tourism. From the 1990s, however, new actors were inserted in the formulation and implementation of policies developed, especially for local hotelkeepers. These, through their association, establishes a leadership relation in the local touristic section, thereby, they could set their hegemony and spread their own interest. The leadership acquired by a group of actors, in the case of Porto de Galinhas, does not mean that trade within the industry were neutralized, but that there is a cognitive framework that confronts the actors involved. In spite of the advances achieved by the work of the mediators in the last decades, that resulted in an amplification and diversification of the activity in the area, as well as the consolidation at the beach, as a tourist destiny of national standout, the position of the place is instable, concerned to the competitiveness, once that there is an situation of social and environmental unsustainability

Effects of Information and Time of Use Pricing on Irish Electricity Demand and Supply

In this dissertation I quantify residential behavior response to interventions designed to reduce electricity demand at different periods of the day. In the first chapter, I examine the effect of information provision coupled with bimonthly billing, monthly billing, and in-home displays, as well as a time-of-use (TOU) pricing scheme to measure consumption over each month of the Irish Consumer Behavior Trial. I find that time-of-use pricing with real time usage information reduces electricity usage up to 8.7 percent during peak times at the start of the trial but the effect decays over the first three months and after three months the in-home display group is indistinguishable from the monthly treatment group. Monthly and bi-monthly billing treatments are not found to be statistically different from another. These findings suggest that increasing billing reports to the monthly level may be more cost effective for electricity generators who wish to decrease expenses and consumption, rather than providing in-home displays. In the following chapter, I examine the response of residential households after exposure to time of use tariffs at different hours of the day. I find that these treatments reduce electricity consumption during peak hours by almost four percent, significantly lowering demand. Within the model, I find evidence of overall conservation in electricity used. In addition, weekday peak reductions appear to carry over to the weekend when peak pricing is not present, suggesting changes in consumer habit. The final chapter of my dissertation imposes a system wide time of use plan to analyze the potential reduction in carbon emissions from load shifting based on the Ireland and Northern Single Electricity Market. I find that CO2 emissions savings are highest during the winter months when load demand is highest and dirtier power plants are scheduled to meet peak demand. TOU pricing allows for shifting in usage from peak usage to off peak usage and this shift in load can be met with cleaner and cheaper generated electricity from imports, high efficiency gas units, and hydro units.
