The objective of this Doctoral Thesis was monitoring, in trimestral scale, the coastal morphology of the Northeastern coast sections of Rio Grande do Norte State, in Brazil, which is an area of Potiguar Basin influenced by the oil industry activities. The studied sections compose coastal areas with intense sedimentary erosion and high environmental sensitivity to the oil spill. In order to achieve the general objective of this study, the work has been systematized in four steps. The first one refers to the evaluation of the geomorphological data acquisition methodologies used on Digital Elevation Model (DEM) of sandy beaches. The data has been obtained from Soledade beach, located on the Northeastern coast of Rio Grande Norte. The second step has been centered on the increasing of the reference geodetic infrastructure to accomplish the geodetic survey of the studied area by implanting a station in Corta Cachorro Barrier Island and by conducting monitoring geodetic surveys to understand the beach system based on the Coastline (CL) and on DEM multitemporal analysis. The third phase has been related to the usage of the methodology developed by Santos; Amaro (2011) and Santos et al. (2012) for the surveying, processing, representation, integration and analysis of Coastlines from sandy coast, which have been obtained through geodetic techniques of positioning, morphological change analysis and sediment transport. The fourth stage represents the innovation of surveys in coastal environment by using the Terrestrial Laser Scanning (TLS), based on Light Detection and Ranging (LiDAR), to evaluate a highly eroded section on Soledade beach where the oil industry structures are located. The evaluation has been achieved through high-precision DEM and accuracy during the modeling of the coast morphology changes. The result analysis of the integrated study about the spatial and temporal interrelations of the intense coastal processes in areas of building cycles and destruction of beaches has allowed identifying the causes and consequences of the intense coastal erosion in exposed beach sections and in barrier islands

The human activities responsible for the ambient degradation in the modern world are diverse. The industrial activities are preponderant in the question of the impact consequences for brazilian ecosystems. Amongst the human activities, the petroliferous industry in operation in Potiguar Petroliferous Basin (PPB) displays the constant risk of ambient impacts in the integrant cities, not only for the human populations and the environment, but also it reaches the native microorganisms of Caatinga ground and in the mangrove sediment. Not hindering, the elaboration of strategies of bioremediation for impacted areas pass through the knowledge of microbiota and its relations with the environment. Moreover, in the microorganism groups associated to oil, are emphasized the sulfate-reducing prokaryotes (SRP) that, in its anaerobic metabolism, these organisms participate of the sulfate reduction, discharging H2S, causing ambient risks and causing the corrosion of surfaces, as pipelines and tanks, resulting in damages for the industry. Some ancestries of PRS integrate the Archaea domain, group of microorganisms whose sequenced genomes present predominance of extremophilic adaptations, including surrounding with oil presence. This work has two correlated objectives: i) the detection and monitoring of the gene dsrB, gift in sulfate-reducing prokaryotes, through DGGE analysis in samples of mDNA of a mangrove sediment and semiarid soil, both in the BPP; ii) to relate genomic characteristics to the ecological aspects of Archaea through in silico studies, standing out the importance to the oil and gas industry. The results of the first work suggest that the petrodegraders communities of SRP persist after the contamination with oil in mangrove sediment and in semiarid soil. Comparing the populations of both sites, it reveals that there are variations in the size and composition during one year of experiments. In the second work, functional and structural factors are the probable cause to the pressure in maintenance of the conservation of the sequences in the multiple copies of the 16S rDNA gene. Is verified also the discrepancy established between total content GC and content GC of the same gene. Such results relating ribosomal genes and the ambient factors are important for metagenomic evaluations using PCR-DGGE. The knowledge of microbiota associated to the oil can contribute for a better destination of resources by the petroliferous industry and the development of bioremediation strategies. Likewise, search to lead to the best agreement of the performance of native microbiota in biogeochemical cycles in Potiguar Petroliferous Basin ecosystem

The objective of this experiment was to evaluate the inclusion of meal of tilapia industrial waster in bullfrog tadpoles' diets (Rana Catesbeina Shaw, 1802). Two hundred fifty tadpoles with initial weight and length of 0,18 +/- 0,05g and 2,50 +/- 0,18 centimeters were used, respectively, they were used and distributed in 25 aquariums of 30 liter each in a complete randomized design with five treatments and five repetitions. The tadpoles were fed four times a day with diets containing 0, 5, 10 and 15% of inclusion of tilapia filleting and another diet with 0% of supplemented tilapia filleting with synthetic methionine, being supplied four times a day at ease. The experiment period was 30 days. The diets with tilapia filleting inclusion and methionine supplementation did not have influence in the final weight and length averages, feed survival and conversion of bullfrog tadpoles. It cam be used until 15% of tilapia filleting inclusion in the bullfrog tadpoles food. The synthetic methionine supplementation in diets for bullfrog tadpoles is not necessary in diets with levels over 0,471/4 of the total methionine.

The experiment constituted in evaluating the acid silage prepared from Nile tilapia (Oreochromis niloticus) filletage industry residues. This silage was prepared in a filetage industry through the residues milling and 5% of ascetic acid addition and stock piling in a period up to until 201 days. Storaged silages in a period of 7, 12, 22, 27, 41, 48, 61, 75, 84, 91, 96, 110, 140, 151, 181, 187 and 201dias were evaluated. Bromatologics analyses of rude protein(PB), etereal extract (EE), humidity (UM), ashes (CZ) and microbiological analyses of Salmonella, total coliforms, faecals and Escherichia coli of the storaged silages in a period of 7, 91 and 201 days were realized. The pH was evaluated in all the storaged periods. Differences (P > 0.05) in the substance of PB, EE, UM and CZ were not observed. A linear increase in PH was observed, being stabilizing in plateau of 4.74. In relation to the microbiological analysis the presence of Salmonella, total coliforms, faecals and E. Coli were not found. Was concluded that the acid silage gotten from tilapia filetage residues produced with the use of 5% ascetic acid can be stored during 201 days without having Salmonella, total coliforms and faecals proliferation.

The present study aimed to understand how and to what extent the electronic forró, currently hegemonic in the music market in the state of Rio Grande do Norte, establishes and maintains relations of domination in the social contexts in which it is produced, transmitted and received. Based, in significant form-content, on the writings of the first generation of theorists of the so-called Frankfurt School (Critical Theory), particularly with Theodor W. Adorno, and systematically using the contributions of the Cultural Studies (from the Centre for Contemporary Cultural Studies of Birmingham) and of the sociology of Pierre Bourdieu, this study aimed to perform, in the fertile intersection of these references, a critical possibility of interpretation of the electronic forró predominantly spread in the state of Rio Grande do Norte. To this end, aiming at a better apprehension of the so-called capital circuits/culture circuits , this study resulted from a qualitative investment of research, based on structured interviews with musicians, entrepreneurs of the sector and music consumers, as well as on the analysis of the themes contained in the official discography of the electronic forró band called Garota Safada (Shameless Girl). As a general empirical conclusion, it was possible to infer that far from the significant presence of domination or mere prevalence of oppositions, there is a relational pluralism of forms of domination and ways of resistances present in the production and consumption of electronic forró, regardless of gender, age, income, education or place of residence. However, the artifices of the cultural industry has been shown to be efficient: from large-scale businessmen to small producers enabled by the so-called open markets . The currentness of the concept of cultural industry is based on the idea that its products are offered systematically (the systematic insistence of everything to everyone) and on the notion that its production primarily meets the administrative criteria of control over the effects on the receiver (capacity of prescription of desires). Thus, the Adornian reflection on the pseudo-individualization leads to the inference that even in some of the most apparent ways of negotiation and/or refusal regarding the consumption of forró, certain behaviors of the cultural industry still prevail both in the very (re)interpretation of the forró and in the choice of other music genres also standardized, rationalized and massified. Therefore, despite the absence of cause-effect relation and the recognition of the popular capacity of re-elaboration and contestation of the media consumption, some world views prevailing in relation to the electronic forró establish or, at least, support some hegemonic ideologies, especially those concerning the life style, consumption and genre relations (fun by all means). Therefore, due the massification of certain songs, some ways of dissemination of values, beliefs and feelings are potentially experienced from the electronic forró. So, it is presumable that in the current advance of the process of semiformation (Halbbildung), the habitus of a part of the youth from the state of Rio Grande do Norte reinforces and is reinforced by the centrality of the trinomial fun, love and sex present in the songs, emphasized in some constructive practices of sense and in certain flows of social significance

As can be inferred by the title of its study The constitutional principle of sustainable development and the utilization of hidrical resources in the oil industry the transcribed pages are dedicated to the approach of the mentioned subjects which, despite being apparently different, will be shown intrinsically connected as goes by the study. The superation of this first step by the reader will lead to an important perception of the title: that the situation requires, urgently, a defined posture, a complete conduct change and, therefore, a modification of the paradigms currently establisheds. To brake barriers, modifying what is lived by, is the ultimate goal. For that, there is no unique path, linear, but there were broached the development themes, the hidrical resources theme and oil and natural gas industry at the necessary points to achieve, by the end, a comprehension for the Brazilian Federal Republic goals in the search for the application of these juridical norms. The ones whom lay down over this study shall notice that, more than a simple approach over these themes (which are still less worked and searched in Brazil), the heavy critic of an instituted and pacifically accepted reality, directly offensive of the constitutional principles. The debate evolves from punctual and specific aspects, it gains life, flies, searching how the juridical order equalizes the economic model to the environment defense. Standing by the possibility of conciliation among constitutional principles, the remodeling of an economic segment is defended, aligning it to the sustainable limits. Development, sustainable, becomes means and goals to the implementation of liberty, capacitating everyone to achieve their goals of life, their libertments, fruit of the inherent antagonism of the Constitution the sustainable development offers, while an axiological vector, a new reality to the economic order, turning it into a motriz element to the fortification of constitutional normative force and for the national development

O trabalho analisa a Indústria Petrolífera em três ambientes de atuação, mundial, nacional e estadual, a partir da observação de sete variáveis, a saber: caráter do petróleo; risco; economia de escala; integração; barreiras; tecnologia e ambiente. O estudo busca perceber as interações e os transbordamentos das variáveis selecionadas em cada um dos ambientes citados, em razão os aspectos econômicos e institucionais presentes nesta atividade, cujos resultados atingem diversos setores da economia e da sociedade como um todo e balizam o próprio processo de inovação da mesma. O estudo está alicerçado no arcabouço teórico neoschumpeteriano acerca dos aspectos voltados para concorrência e inovação, além da questão institucional, e se apóia em dados da Agência Nacional do Petróleo (A.N.P.), Ministério de Minas e Energia (MME), Movimento de Combate à Corrupção Eleitoral / Tribunal Superior Eleitoral (MCCE/TSE), Organization of the Petroleum Exporting Countries (OPEC), International Energy Agency (IAE), Institut Français Pétrole (IFP), United Nations Development Programme (UNDP). Avalia-se que em termos de caracterização da indústria petrolífera nos três ambientes considerados (mundial, nacional e local), há certa similitude no que se refere ao comportamento destas variáveis, com pequenas modificações suscitadas por fatores como grau de desenvolvimento e complexidade da atividade; resultado do ambiente concorrencial e inovativo; e, pelas influências institucionais acerca de atividades e grau de inserção das mesmas no ambiente socioeconômico onde estão localizadas a atividade produtiva e o seu entorno

Foram analisadas 40 amostras de salmouras empregadas na salga por submersão de queijos tipo mussarela, em uma indústria de laticínios do Estado de São Paulo, Brasil, com o objetivo de se conhecer a variação das características físico-químicas e microbiológicas durante o período de sua utilização. Os valores médios do pH, concentração de cloreto de sódio e de proteínas solúveis, desde o preparo da salmoura até o 21° dia de utilização, variaram de 7,21 a 5,76, 27,1 a 24,5 e de zero a 0,126 mg/ml, respectivamente. Por outro lado, os valores médios das contagens de microrganismos mesófilos e do número mais provável de coliformes totais e de origem fecal variaram de 5,8 x 10 UFC/ml a 6,9 x 10(4) UFC/ml, zero a 1,6 x 10(5)/100ml e zero a 1,1 x 10(5)/100ml, respectivamente. Além disso, os valores médios das contagens de bolores e leveduras e de Staphylococcus coagulase positiva, variaram de 0,4 x 10 UFC/ml a 2,0 x 10³ UFC/ml e de zero a 1,3 x 10 UFC/ml, respectivamente. Os resultados encontrados sugerem a existência de condições higiênicas inadequadas durante o preparo e utilização das salmouras, de modo a representar uma importante fonte de contaminação para os queijos. em decorrência deste fato, existe a possibilidade do comprometimento da qualidade dos queijos, de modo a representar risco potencial à população consumidora.

OBJETIVO: Verificar a ocorrência de Staphylococcus aureus em uma amostra de queijo tipo Minas frescal comercializado na cidade de Poços de Caldas, MG, de modo a obter subsídios que permitam avaliar o risco potencial que este produto pode representar para a saúde da população consumidora. MÉTODOS: Foi investigada a presença e o número de cepas de Staphylococcus aureus em 80 amostras de queijo tipo Minas frescal produzido artesanalmente e comercializado na cidade de Poços de Caldas, MG, Brasil. RESULTADOS: Os resultados obtidos evidenciaram a presença de S. aureus em 40 (50,0%) amostras, cujas contagens revelaram valores médios em torno de 10(5)/g. CONCLUSÕES: Tais achados parecem ser extremamente preocupantes, pois além de se situarem acima do limite máximo de 10³/g estabelecido pelo Ministério da Saúde, estes valores mostraram-se muito próximos dos requeridos para a produção de enterotoxinas em quantidades suficientes para a ocorrência de surtos de intoxicação alimentar estafilocócica.

Fifty six crossbred kids Parda Alpina x Gurgueia were separeted into four groups of 14 (seven male and seven female) and submited to four treatments with different levels of milk goat substitution by cheese serum. The treatments were : T1=milk goat (testify); T2=15% serum at 23 days and 33% at 55 days; T3=15% serum starting from 16 days, 33% on 23 days and 51% on 72 days of age; and T4=33% on 16 days and 69% of liquid diet in the final fase. At 92 days of age, all animals were slaughtered for carcass evaluation. Pallete were separeted from 20 male animals (five by treatment) and the physical and chemical analysis of the meat were realized using these materials. The studied characteristics were: total weight (TW), meat weight (MW), bone weigth (BW) of the pallete, and percentage of umidity (U), ashes (A), protein (P), fat (F) and pH of the pallete meat. There was significant effect of the treatment over F. Means of PW, A and BW were, respectively 491, 342 and 149.8 g. The meal represented 69,6% of total pallete weight. Means of U, A, P and F were 73, 1.0, 19 and 1.95%, respectively. The pH was 6.7. Results allow to conclude that only the fat percentage of the meat was modified, due to the administration of serun milk on the liquid diet of the kids, during the milking fase.

No município de Itatiba-SP, no período de março a julho de 2007, foi realizado um experimento com o objetivo de avaliar doses de nitrogênio e potássio e espaçamentos entre plantas na produtividade e classificação de brócolos para indústria. O experimento foi instalado sob delineamento de blocos ao acaso, com os tratamentos em esquema fatorial 5 x 4, e três repetições, sendo avaliadas as doses de nitrogênio-potássio: 105-105; 157,5-157,5; 210-210; 262,5-262,5 e 315-315 kg ha-1 de N e K2O e os espaçamentos entre plantas: 0,2; 0,3; 0,4 e 0,5 m. O espaçamento entre linhas foi de 0,8 m. Foram avaliados o teor foliar de nitrogênio (TN) e de potássio (TP), produtividade de inflorescência (PI), produtividade de floretes (PF), rendimento industrial (RI) e classificação dos floretes com base em seu comprimento: PF5 (<5 cm); PF57 (>5 e <7 cm); PF79 (>7 e <9 cm) e PF9 (>9 cm). Maiores espaçamentos entre plantas proporcionaram maior TN e menores PI e PF. As doses NK e os espaçamentos entre plantas não influenciaram significativamente o TP e o RI. As maiores produtividades de inflorescências (22,08 t ha-1) e de floretes (17,09 t ha-1) foram obtidas com 0,20 m entre plantas e 315 kg ha-1 de N e de K2O. Maior percentagem de floretes na classe PF5 foi obtida no menor espaçamento entre plantas. As doses NK e os espaçamentos entre plantas não influenciaram as percentagens de floretes nas classes PF79 e PF9.
