Determinação de Cd, Cu, Ni, Pb e Zn em águas marinhas oriundas da Bacia Potiguar utilizando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

The DGT technique has been used to determine and better understand the dynamics and bioavailability of metals in the sea near to marine outfalls. In this work, the DGT was assessed for the determination of Cd, Pb, Cu, Zn and Ni in marine water samples from Potiguar Basin in its conventional aspect (binding agent, Chelex-100 and diffusive agent: Diffusive polyacrylamide gel (D) and restrictive (R)) and determination of Pb and Cd through its alternative aspect (binding agent: Saccharomyces cerevisiae immobilized in agarose gels and diffusive agent: 3MM Chromatography Paper). The deployment curves for long periods of immersion in the sample, showed a good linear correlation for the conventional aspect to Zn (D: R²=0.9586, R: R²=0.9444), Ni (D: R²=0.9789, R: R²=0.9286) and Cu (D: R²=0.764, R: R²=0.8143), and alternative to Pb (R²=0.9228) and Cd (R²=0.9673). The results of the organic and inorganic composition analysis in conventional aspect, showed that for every element there is no significant fraction of organic compounds in the sample. In addition, considering the alternative aspect, the comparison of obtained and expected masses suggests that some of the Pb is not labile and that the main retention mechanism of Pb for S. Cerevisiae occurs through ion exchange

Extrafiscalidade: análise da norma potiguar regulamentadora do imposto sobre propriedade veicular automotora à luz da tutela ambiental

From the second half of the twentieth century the state bega n to use exaction beyond your fiscalist character, also as a means of alignment deformities economic and social balance, influencing in different directions, according to economic, social and political policy. It is what is usually called the extrafiscalit y. It is in light of this phenomenon and the constitutional perspective, the present work aims to analyze item IV of article. 8 of Law n. 6.967/96, regulatory Property Tax Vehicle Automotive (property taxes) in the State of Rio Grande do Norte, in view of its possible incompatibility with the principles of the Basic Statute and with international guidelines for protection of the environment The problem of this research is Seated in art. 225 of the Constitution, which provides that everyone has the right to an ecologically balanced environment. From the reading of this standard, extracted it is the responsibility of the state protecting the environment, which requires the adoption of suitable actions to that end. However, we look to state law cited follows th e constitutional path, since it exempts the collection of property taxes automotive vehicles with over 10 years of manufacturing, which could encourage the conservation of a fleet of old vehicles, mostly more polluting and harmful to the environment and hu man health. Would the state legislature oblivious to the constitutional principles and the global trend of environmental preservation? Thus questions whether such an incentive for more polluting vehicles, emitting more gases in the atmosphere. Moreover, th e international community is already moving through important conventions in an attempt to minimize and control global warming and climate change. Predicting the theme in CF/88 demonstrates that the country is no stranger to the issue. Thus, the work is a retelling of Law No. 6.967/96 order to check whether it is compatible with the existing system. The methodology consists of a documentary, deductive, dialectical literature. At the end of the survey, it was found that provide a tax benefit to these vehicle s is encouraged to maintain them in circulation and contribute to the increase in air and noise pollution, in addition to the traffic problems generated. Thus, this potiguar anything standard can be expressed extrafiscality because the medium and long term there is encouragement and worsening environmental problem. Despite the ability to pay clause, but this remission is an affront to legally protected interests. Thus, this device goes in reverse order compared to the values of the legal system and in relat ion to sustainable development. Modern Tax Law should be used as a tool to achieve the purposes collimated by the State, and not otherwise. It was noticed that the vast majority of Brazilian states does not follow this rule, including Mato Grosso and Minas Gerais have no such exemption. Therefore, the RN State does not constitute a model for sustainable public policies, nor example of environmental protection by state law.

Programa Nacional de Incentivo à Leitura - PROLER: avaliação da implementação pelo Comitê Potiguar

The National Reading Incentive Program (PROLER) is a national initiative to promote and encourage reading throughout the country, linked to the National Library Foundation (FBN) of the Ministry of Culture (MinC). This research aims to assess the PROLER’s implementation process in the state of Rio Grande do Norte, from the actions of their local committee. The framework is based on contextualize the policies that seek to encourage the book and reading, as well as the processes of implementation and evaluation of public policies. The research is understood as a qualitative descriptive-exploratory study, comprising a single case study. Makes use of semi-structured interview as a tool for data collection, which was attended by 8 members of Potiguar Committee as respondents. The techniques of bibliographical and documentary analysis were used for the analysis and discussion of data obtained from surveys and documents on PROLER; as to the content of the interviews, the technique used was the analysis of conversations. As for the results, the existence of four barriers to program implementation in the state that are worth mentioning is observed: a) the political-administrative discontinuity; b) the limited resources and few partnerships; c) the management of school libraries and absence from the post of librarian in the state and; d) the absence of a process or assessment tool able to evaluate the results or the impacts of actions taken by the Potiguar Committee. It was noticed that these limiting four come PROLER making the implementation of the Rio Grande do Norte a process that, although complying with the national regulations of teacher training and follow school libraries and their needs, not flawed to develop assessments that can measure program impacts, making the feedback process of ineffective policy. Another observation of this study is seen in the fact that the Committee did not get enough to supply their shares resources, as well as not being able to articulate new partnerships, thus contributing negatively to the scope of the program form and, consequently, for the effectiveness of their actions. Has even mentioning the fact that the Committee do nothing regarding the mismanagement of the libraries that are in their care, ie, do not use the power of coercion as guaranteed by the National Policy on Reading and federal laws that treat the school library, and is therefore ineffective in relation to compliance with the program guidelines

A OAB no processo de transformação da sociedade brasileira: a seccional potiguar como espaço de redemocratização (1979-1988)

The period known as the Military Dictatorship (1964-1985) was a period of history marked by Brazil's control of state power by the Armed Forces together, this started with the Civil-Military Coup of April 1964. Was characterized as a time where political freedoms of expression and were placed in check by authoritarian and repressive measures taken by the military governments. The sectional potiguar of the Ordem dos Advogados do Brasil (OAB / RN), and the Federal Council of the institution, supported the establishment of this scam, but from the 1970s undertook measures that sought to corroborate the struggles around democracy the country, which has consolidated its image as a defender of democratic order. With the title inspired by the XII Meeting of OAB in October 1988, the research aims to analyze the participation of OAB / RN and its members within the Brazilian democratization. This analysis begins in 1979 with the participation of the entity in discussions Amnesty Policy to the promulgation of the 1988 Constitution, since the Constitution is the beginning of a full rule of law. We seek to understand the object as a space for democratization, combining the concepts of History, Memory and Politics. In the analyzes are guided theoretically by Jacques Le Goff, Pierre Nora, Maurice Halbwachs, Pierre Bourdieu and Hannah Arendt. Be rebuilt the period of democratic rule in the land potiguares birthing shares of OAB / RN, particularly in the following events: Amnesty Policy 1979, the mobilizations around the campaign of "Direct Now" and the 1988 Constitution We make use of legislation. minutes, papers and interviews built on Oral History.

Sustentabilidade e gestão da pesca artesanal na costa do Semiárido Potiguar (RN), Brasil

T he socio - economy of the coastal municipalities of Rio Grande do Norte semiarid coast was analyzed th r ou g h by the actors, ant hropogenic implications, fishing environment and composition of its fish fauna, as well as the trend of product ion landed by the artisanal fleet with the aim of identifying the sustainability and management. In this study, were used participatory methodologies, monthly data of rainfall between September 2001 and December 2010; landings of the artisanal fleet during January 2001 to December 2010; and socioeconomic (IBGE, 2002/2010), (IDEMA, 2011/2012), (MPA, 2010; 2012), UNDP and MS (2013). Based on these data, we performed analysis of variance were performed using the method of Analytic Hierarchy Process (HAP) and s tatistical models of multiple regression and time series. It was identified that the occupation of the coastal and marine zone through salt industry, tourism, shrimp farming, oil and gas and wind energy reconfigured the environment and attracted new actors . Rainfall influenced the catches, of which 35% occur in the rainy season, 40% in the dry season and 25% independent. Production increased 55%, in the period analyzed , being landed in 31 ports spread over 11 municipalities, cap tured in environments mangrov e/ estuarine (23%), coastal (46%) and oceanic (31%). Despite market up 41 species, were commercialized in the region production concentrated in eight, mainly landed in Macau and Caiçara North, by vessels of small and medium - sized (motorized and sailboats) . Highlights included three species ( Hirundichthys affins , Coryphaena hippurus and Opisthonema oglinum ), which together accounted for 63.3% of the whole volume. It was found that the motorized vessels tripled in number while sailboats reduced by half. Landin gs by different types of vessels tend to increase over time, while the small sailboats vessels, decrease. The introduction of more new motorized vessels and sailboats also tend to increase production. The study concluded that GDP and HDI of coastal countie s increased however inequality persisted. The potential of artisanal fishing is in the stage “ unfavorable ” of development and the trend in fish production is to grow over time and with the entry of more vessels. However, it is urgent that the state actions to promote and enhance planning to restore fish stocks in a sustainable and profitable fisheries standards. Therefore, it is recommend the strategic use of natural resources in a sustainable development perspective.

Caracterização morfológica-sedimentar do vale inciso Apodi-Mossoró e plataforma continental adjacente - Bacia Potiguar Offshore

Systems of incised valleys have been studied in different continental shelves, including the Brazilian continental margin. The interest to characterize this feature is given by the information that it can provide variations on sea level, as well as the ability to host economically significant quantities of hydrocarbons in reservoirs located in deposits filling of the incised valleys. This thesis has the overall objective to characterize the morphology and sedimentary cover of the incised valley Apodi-Mossoró, located in the Northern Continental shelf of Rio Grande do Norte state, adjacent to Areia Branca city. The methodology included the integration of satellite imagery, bathymetric data, sedimentological data, shallow seismic, and the identification of foraminifera. The results indicate that the ApodiMossró incised valley is currently formed by two channels, shallow channel and deep channel, which have distinct morphological and sedimentological characteristics. The deep channel has connection with one of the heads of the Apodi Canyon, located in the slope area. The acquisition, processing and interpretation of shallow seismic data allowed the recognition of the depositional surface, erosional surface, discordance, and sismofaceis. The erosional surface mapped from shallow seismic sections is possibly a indicative of an ancient surface of valley incision, where it would probably be associated with the limit Pleistocene/Holocene. Different sismofaceis were identified and reflect the rise in sea level with standards sometimes agradacional, sometimes progradational. The thickness of sediments on this surface was estimated at a maximum of 22m thick in the central portion of the incised valley. Statistically, there are differences between the adjacent continental shelf and channels, and between these channels, for the content of calcium carbonate, organic matter, sand and mud perceptual, except for the gravel grain size. The analysis of living and dead foraminifera showed the presence of fifty species distributed in regards to morphology, depth and type of sediment. Four type of seismic echocharacteres were identified and mapped, as well as their bedforms, indicating different sedimentary processes along the incised valley. The integration of results suggests an activation of the Apodi-Mossoró incised valley in the Late Pleistocene.
