Turismo, território e políticas públicas: uma análise do destino João Pessoa/PB

This study presents an approach to tourism activity from the perspective of the territory, analyzing the importance of the roles of the State and public policies for tourism development. Tourism in the northeastern region of Brazil begins to take its rise from the late 1970 through public policies, whose goal was to provide the necessary conditions for tourism development. The tourism public policies were the key elements in the production process of tourist territories in the region. In the state of Paraíba, the public authorities elected the coastline as the main attraction and the state capital, João Pessoa, as the locus for the tourism development, with the city receiving a series of public policies. In this context, this research aims to analyze the development process of three specific public policies for tourism development in João Pessoa: The (mega)Projeto Costa do Sol (1988), the PRODETUR/PB I and II (1997 e 2005) and the Plano Estratégico de Desenvolvimento do Turismo na Paraíba, the Plano Amanhecer (2000). This study was guided by the question that even having been contemplated by the tourism public policies, João Pessoa still remains in a peripheral position in the regional tourism market. The methodological procedures for this study were literature and documents research and semi-structured interviews with tourism public officials and representatives from local tourism trade. The research came to prove that the discontinuity between governmental administrations hampered the implementation process of the tourism public policies studied. It was observed that the implementation of tourism public policies in the long term depends on the interaction between governments, as well as the collective political will to develop tourism in Joao Pessoa

A mineração artesanal e de pequena escala em pegmatitos e cerâmica no município de Parelhas, região do Seridó/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Seridó, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

Estratégias de Produção in vitro de Bioinseticida Viral: influências do Isolado, da Cinética e do Modo de operação

Societal concerns about environmental sustainability has lead to the development of ecologically-friendly alternatives to chemical insecticides for crop protection. One such alternative is biological pest control. In particular, baculoviruses are well suited as insect biopesticides due to their narrow host specificity and relative ease of propagation. In Brazil, the baculovirus Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) is the main biological control agent employed for the soybean pest, Anticarsia gemmatalis. This baculovirus biopesticide is currently produced using caterpillars, but increasing market demand for the product has encouraged the development of an in vitro manufacturing process, which can be scaled up to much higher virus productivities. In this study, three wild-type AgMNPV isolates (AgMNPV-2D, AgMNPV-MP2 and AgMNPV-MP5) and a recombinant form (vAgEGT-LacZ) were characterised in terms of occlusion body (OB) production and infection kinetics, to enable future optimisation of the in vitro production process. These viruses were propagated using a Spodoptera frugiperda (IPLB-SF21) insect cell line grown in shaker-flask batch cultures. Among the virus isolates tested, AgMNPV-MP5 was found to be the best producer, yielding (5.3±0.85)x108 OB/mL after 8 days post infection. The characterisation of vAgEGT-LacZ propagation in suspension cell cultures has not been previously reported in the literature; hence it became the main focus for this thesis. In particular, it was carried out a study on the effect of the multiplicity of infection (MOI) on OB production. Five successive batches were performed getting a final production (8.9±1.42)x1014 occlusion bodies, considering that production is related for a bioreactor with final volume of 10m3. A low MOI associated with a fed-batch process for vAgEGT-LacZ production was found to support a 3-fold higher OB yield when compared to the default batch process (1.8x107 and 5.3x107 OB/mL, respectively). This yield is competitive with regards to the production process.

A participação dos residentes no processo de produção do território turístico em Canoa Quebrada-CE

The work present entitled the participation of resident in the production process of the tourist territory in Canoa Quebrada/CE has as objective analyse of which form the site population participates of the manufacturing process and appropriation of the territory s tourist Canoa Quebrada CE , in period undestood between from 1980 to the present day. The theoretical variable about which rest this search is the concept the territory expressed in the manifested in the process deterritorialization that always appears in conjuction whith the reconstruction of territories, in other words, the process of repossession. The migratory movement of new residents acts in the new sociospatial configuration that location, form new territoriality and (de) territorializing in space turistificado reflected dialectically through the emergence of a new sociospatial setting consisting of forms and images expressed physically in place.Finish the job showing that the participation of resident native and nonnative in the production process of the tourist territory in Canoa Quebrada occurred unevenly characterized by dominance of a small group, who has control of the practice of this activity, thus appears that tourism can be tendentious, since a large portion of the population does not benefit from their results, having a exclusion with various impacts that directly affect the everyday social population

Incrustação em poço produtor de petróleo e gás natural: um estudo de caso

Water and gas is a common by - product of the oil production process. Production may be compromised by the precipitation of inorganic salts in both the reservoir and producing well, through scale formation. This precipitation is likely the cause of the formation damage. High temperatures and h igh pressures (HTHP) may favor the precipitation of insoluble salts. The most common types of scale in oil fields are calcium carbonate and calcium sulphate, strontium and barium sulphate. New types of scale formation have attracted special attention such as zinc sulphide and lead. This precipitation may occur in the pores of reservoir rocks, in the production string and in equipment, causing obstructions and consequent production losses. In this study, the influence of well depth on incrustation compositio n was investigated to design removal treatments and assess the behavior of these deposits along the string, through the analysis of pressure and temperature. Scale residues were recovered from the inside of the production string of an oil and gas well duri ng the string removal operation. A total of 10 samples from different depths (15.4 m to 4061.5 m) were obtained. Initially a dissolution test was conducted in weak acid, similar to that used in removal operations with this type of scale formation. Majority composition was defined and confirmed by dissolution tests using X - Ray Fluorescence Spectroscopy (XRF), X - Ray Diffraction (XRD) and Scanning Electron Microscope (SEM) techniques. Residues with distinct characteristics were observed in different proportion s, showing a tendency toward increased and/or decreased mass with depth. In the samples closest to the surface, typical sandstone residues were found, with calcium (45% Ca) as the metal of highest concentration. The obtained results indicate correlations o f the scale types studied with the depth and, consequently, with the thermodynamic conditions of pressure and temperature.

Produção do espaço e reestruturação produtiva do setor de laticínio no Rio Grande do Norte

Since the 1970s, Brazil has gone through several changes in its economic and productive structures, which have symbiotic relationship with the organization and dynamics of the Brazilian territory. This set of economic, social and technical-scientific transformations developed in the amid the productive capital restructuring, a process that occurs on a global scale, but that effective with particularities in different places. Adopting this presuposition the present research had as main objective analyze the productive restructuring of the dairy sector in Rio Grande do Norte, highlighting its relationship with production process / organization of space and its impact on the social relations of production. The adopted methodology to elaborate of this study was based on the achievement a bibliographic review with regard to proceedings of production of space and productive restructuring, document research about the dynamics of the dairy sector in Rio Grande do Norte, as well as on regulatory instructions governing the dairy production in Brazil, we achieve parallel secondary data collection, with official organs such as IBGE, EMATER and SINDLEITE. Another important methodological resource was the realization of the field research, which enabled us to empirically understand the distinct realities lived by agents acting on milk production system in Rio Grande do Norte. The analyzes performed nevertheless evidence that the restructuring process in the dairy sector is fomented, greatly by state,that finance, encourages and normatizes the production of milk in the country. In the specific case of Rio Grande do Norte, this process is boosted by the creation of "Programa do Leite," which by constituting of an institutional market, contributes to the strengthening and expansion of industries, the detriment of the artisanal processing sector. Nevertheless family farmers continue to act in the activity, be only producing and trading fresh milk, supplying milk to processing units, mediating the production of their peers or by the craft benefiting milk in traditional cheese factories presents in the entire state of Rio Grande do Norte. The results reveal that it is a complex web of social relations of production that are established at the heart of laticinista activity in the Rio Grande Norte, these are summarily marked by relations of competition and complementarity between industrial and artisanal processing of milk

Vazios urbanos e a dinâmica imobiliária na produção do espaço em Natal

In Brazil, the discussion about the urban voids appear related to the capitalist urban expansion process, when the urban growth act the cities were expanding toward the periphery, leaving in the interstices vacant land, kept out of the market waiting for the real estate valuation. In Natal, the formation of voids was triggered by the process of fragmentation of space promoted mainly by the urban sprawl with the emergence of new neighborhoods, lots of openings, housing developments and the emergence of new lines of commercial centrality. In this sense, this study aims to understand the role played by urban voids in the real estate dynamics and the production process of the Natal city space. For this, it was adressed the concept building on the conception of different authors and were characterized four types of gaps that best explained the phenomenon in the context of the work proposal addressed, such as idle, empty expectant, empty-brownfield areas and institutional areas. For each of these events were considered an example in the general context of the city through semi-structured interviews with technicians, managers and public officials in promoting the city and /or related to management of urban voids.

O processo de elaboração do plano de preservação do conjunto urbanístico de Brasília: uma representação conceitual da política de preservação urbana no DF

This research aims to provide a reflection on the preservation practices of Brasilia as Cultural Heritage in four analytical/political dimensions: conceptual, urban, political-institutional and legal. In order to do that, the preparation process for the Plan for the Preservation of Brasilia Urban Set (PPCUB) was taken as research object. This preservation plan is representative of the context which determines the relation between goals and preservation practices in the social production process of urban space. Designed by Lucio Costa in 1957, Brasilia received the Cultural Heritage title 27 years later, in 1987. It was recognized a World Heritage Site by the United Nations Educational, Scientific and Cultural (UNESCO) in the same year as it "represents a unique artistic piece of work, a masterpiece of creative genius"; and "an outstanding example of a type of construction or architectural compound that illustrates a significant stage in history" (SILVA, 2003). Brasilia’s urban conception, also recognised in the district and federal levels, gives prominence to the 'urban scales' – monumental, residential, gregarious and bucolic – as the main aspects to be preserved. Despite being an undoubted representative, Brasilia seemingly displays a contradiction. On the one hand, the essential value of the city’s urban design is acknowledged as cultural heritage at international, national and district levels. On the other hand, numerous ways of urban interventions disregard the principles of that conception. In 2012, the international Monitoring Report raised some issues which highlight the following main needs: primary need for clear definition of the urban scales’ characteristics and boundaries; definition of a legal framework that conciliates national and district laws of occupation and use of land; creation of inter-sectors executive authority with both decision-making and financial autonomy; and promotion of heritage educational programs. This report also proposes "to cancel the current process of approval conducted by PPCUB and establish a formal consultation process through a committee made up by GDF and IPHAN, which will enable the active participation of University of Brasilia, the Architects Association, ICOMOS and local organizations" (SEDHAB, 2010). Already in its drafting process, the international recommendations evidence that preserving Brasilia’s urban design conception is not among the goals to be achieved. Thus, this research highlights that the intentional nature of PPCUB’s plans does little towards realizing the current proposals.

Estudo da absorção das espécies pesadas do gás natural em octanol: efeitos da temperatura e vazão

In the oil industry, natural gas is a vital component of the world energy supply and an important source of hydrocarbons. It is one of the cleanest, safest and most relevant of all energy sources, and helps to meet the world's growing demand for clean energy in the future. With the growing share of natural gas in the Brazil energy matrix, the main purpose of its use has been the supply of electricity by thermal power generation. In the current production process, as in a Natural Gas Processing Unit (NGPU), natural gas undergoes various separation units aimed at producing liquefied natural gas and fuel gas. The latter should be specified to meet the thermal machines specifications. In the case of remote wells, the process of absorption of heavy components aims the match of fuel gas application and thereby is an alternative to increase the energy matrix. Currently, due to the high demand for this raw gas, research and development techniques aimed at adjusting natural gas are studied. Conventional methods employed today, such as physical absorption, show good results. The objective of this dissertation is to evaluate the removal of heavy components of natural gas by absorption. In this research it was used as the absorbent octyl alcohol (1-octanol). The influence of temperature (5 and 40 °C) and flowrate (25 and 50 ml/min) on the absorption process was studied. Absorption capacity expressed by the amount absorbed and kinetic parameters, expressed by the mass transfer coefficient, were evaluated. As expected from the literature, it was observed that the absorption of heavy hydrocarbon fraction is favored by lowering the temperature. Moreover, both temperature and flowrate favors mass transfer (kinetic effect). The absorption kinetics for removal of heavy components was monitored by chromatographic analysis and the experimental results demonstrated a high percentage of recovery of heavy components. Furthermore, it was observed that the use of octyl alcohol as absorbent was feasible for the requested separation process.

Um olhar sobre a música gospel: a lógica simbólica e de mercado do Ministério de Louvor Diante do Trono

This study aims to understand how the gospel music genre - based on the gospel band Ministério de Louvor Diante do Trono - articulates itself to the logic of the market by its insertion in the music industry and use of symbolic logic in the available songs of their Cds and DVDs. Our research is a case study, methodologically being the descriptive analysis of the production process, distribution and broadcasting of the band's CDs and functional analysis of the music that permeates the entire thesis. The following songs are presented as an analytical corpus: Preciso de Ti,Quero me Apaixonar, Tua Visão, Creio, Tu Reinas e Tetelestai. Our hypothesis is that religious institutions - as a field responsible for the structure which maintains gospel artists - experiences a new dynamic that consists of a superficial modernity, ratified in the ways the symbolic goods produced communicate, that is, simulate a religious modernity maintaining traditional values regarding the dogmas of religion , but incorporate business and advertising procedures in the dissemination of its products The results point to gospel music as mediation, part of the religious ritual sometimes as prayer and other as preaching, stimulating consumption and entertainment, and performing as a device in the making of symbolic goods.

A confiança interorganizacional nas compras

This research is part of the field of organizational studies, focusing on organizational purchase behavior and, specifically, trust interorganizational at the purchases. This topic is current and relevant by addressing the development of good relations between buyer-supplier that increases the exchange of information, increases the length of relationship, reduces the hierarchical controls and improves performance. Furthermore, although there is a vast literature on trust, the scientific work that deal specifically at the trust interorganizational still need further research to synthesize and validate the variables that generate this phenomenon. In this sense, this investigation is to explain the antecedents of trust interorganizational by the relationship between the variable operational performance, organizational characteristics, shared values and interpersonal relationships on purchases by manufacturing industries, in order to develop a robust literature, most consensual, that includes the current sociological and economic, considering the effect of interpersonal relationships in this phenomenon. This proposal is configured in a new vision of the antecedents of interorganizational trust, described as significant quantitative from models Morgan and Hunt (1994), Doney and Cannon (1997), Zhao and Cavusgil (2006) and Nyaga, Whipple, Lynch (2011), as well as qualitative analysis of Tacconi et al. (2011). With regard to methodological aspects, the study assumes the form of a descriptive, survey type, and causal trace theoretical and empirical. As for his nature, the investigation, explicative character, has developed a quantitative approach with the use of exploratory factor analysis and structural equation modeling SEM, with the use of IBM software SPSS Amos 18.0, using the method of maximum verisimilitude, and supported by technical bootstraping. The unit of analysis was the buyer-supplier relationship, in which the object under investigation was the supplier organization in view of the purchasing company. 237 valid questionnaires were collected among key informants, using a simple random sampling developed in manufacturing industries (SIC 10-33), located in the city of Natal and in the region of Natal. The first results of descriptive analysis demonstrate the phenomenon of interorganizational trust, in which purchasing firms believe, feel secure about the supplier. This demonstration showed high levels of intensity, predominantly among the vendors that supply the company with materials that are used directly in the production process. The exploratory and confirmatory factor analysis, performed on each variable alone, generated a set of observable and unobservable variables more consistent, giving rise to a model, that needed to be further specified. This again specify model consists of trajectories was positive, with a good fit, with a composite reliability and variance extracted satisfactory, and demonstrates convergent and discriminant validity, in which the factor loadings are significant and strong explanatory power. Given the findings that reinforce the model again specify data, suggesting a high probability that this model may be more suited for the study population, the results support the explanation that interorganizational trust depends on purchases directly from interpersonal relationships, sharing value and operating performance and indirectly of personal relationships, social networks, organizational characteristics, physical and relational aspect of performance. It is concluded that this trust can be explained by a set of interactions between these three determinants, where the focus is on interpersonal relationships, with the largest path coefficient for the factor under study

A organização do processo de projeto de arquitetura no meio profissional: uma análise da produção em escritórios

This paper examines, through case studies, the organization of the production process of architectural projects in architecture offices in the city of Natal, specifically in relation to building projects. The specifics of the design process in architecture, the production of the project in a professional field in Natal, are studied in light of theories of design and its production process. The survey, in its different phases, was conducted between March 2010 and September 2012 and aimed to identify, understand, and analyze comparatively, by mapping the design process, the organization of production of building projects in two offices in Natal, checking as well the relationships of their agents during the process. The project was based on desk research and exploration, adopting, for both, data collection tools such as forms, questionnaires, and interviews. With the specific aim of mapping the design process, we adopted a technique that allows obtaining the information directly from employee agents involved in the production process. The technique consisted of registering information by completing daily, during or at the end of the workday, an individual virtual agenda, in which all agent collaborators described the tasks performed. The data collected allowed for the identification of the organizational structure of the office, its hierarchy, the responsibilities of agents, as well as the tasks performed by them during the two months of monitoring at each office. The research findings were based on analyses of data collected in the two offices and on comparative studies between the results of these analyses. The end result was a diagnostic evaluation that considered the level of organization and elaborated this perspective, as well as proposed solutions aimed at improving both the organization of the process and the relationships between the agents under the lens analyzed

Estudo da moagem de alta energia e sinterização de pós compósitos W-Cu

The Tungsten/copper composites are commonly used for electrical and thermal objectives like heat sinks and lectrical conductors, propitiating an excellent thermal and electrical conductivity. These properties are dependents of the composition, crystallite size and production process. The high energy milling of the powder of W-Cu produces an dispersion high and homogenization levels with crystallite size of W very small in the ductile Cu phase. This work discusses the effect of the HEM in preparation of the W-25Cu composite powders. Three techniques of powder preparation were utilized: milling the dry with powder of thick Cu, milling the dry with powder of fine Cu and milling the wet with powder of thick Cu. The form, size and composition of the particles of the powders milled were observed by scanning electron microscopy (SEM). The X-ray diffraction (XRD) was used to analyse the phases, lattice parameters, size and microstrain of the crystallite. The analyse of the crystalline structure of the W-25Cu powders milled made by Rietveld Method suggests the partial solid solubility of the constituent elements of the Cu in lattice of the W. This analyse shows too that the HEM produces the reduction high on the crystallite size and the increase in the lattice strain of both phases, this is more intense in the phase W

Influência da adição de cálcio nas propriedades de pastas geopoliméricas destinadas a cimentação de poços de petróleo

Nowadays, the search for new technologies that are able to follow the upcoming challenges in oil industry is a constant. Always trying properties improvements of the used materials, looking for the best performance and greater life time. Besides the search for technologies that show an improvement of performance, the search for materials environmentally correct along the whole production process. In Oil well cementing, this search for new technologies passes through the development of slurry systems that support these requests and that are also environmentally friendly. In this context, the use of geopolymer slurries is a great alternative route to cementing oil wells. Besides having good properties, comparable to Portland cement slurries, this alternative material releases much less CO2 gas in the production of their root materials when compared the production of Portland cement, which releases tons of CO2. In order to improve the properties of geopolymer slurries has been added Calcium Oxide, as observed in other studies that slurries where the Calcium is present the values of compressive strength is greater. The addition has been realized based in the CaO/SiO2 molar ratio of 0.05, 0.10 and 0.15. Have been performed compressive strength tests, thickening time, rheology and fliud loss control test of the slurries, following NBR 9831, as well as the physical chemical characterization of XRD, SEM and TG. Has been observed in most of the tests the slurries follow a tendency until the ratio of 0.10, which inverses in the ratio 0.15. This behavior can be explained by two phenomena that occur simultaneously, the first one is the break of the polymer chains and a consequent increase in molucules mobility, which prevails until the ratio of 0.1, and the second is possible approach of the chains due to the capacity of the calcium ions stabilize the charges of two different aluminum. There is only one linearity in the mechanical behavior that can be attributed to the appereance of the C-S-H phase. Based on this, it is concluded that the phenomenon of breaking the polymer chains predominates until the ratio of 0.1, causing an increase of the filtrate volume, lower rheological parameters and increasing thickening time. From the ratio of 0.15 the approach of the chains predominates, and the behavior is reversed
