Catalisadores bifuncionais à base de silicoaluminofosfato e fosfatos de nióbio para emprego em reações de hidroisomerização e hidrocraqueamento do n-hexadecano

Lubricants and cutting middle distillates typically have large amounts of n-paraffins to increase its freezing point and fluidity. Accordingly, the removal of n-paraffins of long chain lubricants oils and diesel is essential to get a product with good cold flow properties. The development of new catalysts, which exhibit thermal stability and catalytic activity for the hydroisomerization reaction is still a challenge. Thus, silicoaluminophosphates (SAPO) were synthesized by different routes. Have been used also post-synthesis treatment for obtaining hybrid structures and others synthesis have been carried out with mesoporous template (soft and hard-template). Therefore, SAPO have been impregnated with H2PtCl6 solution by the incipient wetness method. Then assessments of catalytic activities in hydroisomerization and hydrocracking reactions of hexadecane have been held. Besides SAPO, niobium phosphate - NbP - were also impregnated with platinum and evaluated in the same reaction. After impregnation, these catalysts have been characterized by X-ray diffraction (XRD), nitrogen adsorption, infrared spectroscopy with adsorbed pyridine (IV-PY), scanning electron microscopy (SEM) and resonance nuclear magnetic 29Si (29Si-NMR). The characterization results by XRD have shown that it has been possible to obtain mesoporous SAPOs. However, for the syntheses with soft template there was collapse of the structure after removal of the organic template. Even so, these catalysts have been actives. It was possible to obtain hybrid materials through the synthesis of SAPO-11 made with hard templates and by means of post-synthesis treatments samples of SAPO-11. Moreover, NbP has shown characteristic XRD of amorphous materials, with high acidity and were active in the conversion of hexadecane.

A formação e o desenvolvimento de arranjos cooperativos sob a ótica da imersão social e da economia dos custos de transação: um estrudo de caso na Coopercam e na Unipesca

The current study analyzes the birth and development of two strategic alliances established between shrimp producers in Rio Grande do Norte: the Unipesca and the Coopercam. To achieve this aim, two approaches which, at first sight, could be considered contradictory were used: the Transactional Costs Economy and Embeddedness. The first approach is fundamentally based in the studies of Williamson (1985; 1991; 1996; 1999; 2000; 2002). Embededness, on the other hand, went through the review of a series of authors, such as Burt (1992), Granovetter (1973; 1985), Uzzi (1997), Gulati (1994; 1995; 1997; 1998; 1999; 2000), Nielsen (2005), Ring (2002), Ring and Van de Ven (1994), Zafirovski (2002), among others. To analyze the birth and development of the cooperatives in this study, Gulati s work (1998) was used. This study shows the steps to be studied for a better comprehension of an alliance: the decision of starting an alliance and the choice of the partners, the decision about the governance structure, the evolution of the alliance and the development of the companies which established this partnership. To carry this study out, a study case accordingly to Yin s proposal (2001) was adopted. Semi-structured interviews with pre-defined plots were conducted in two phases: in the beginning of 2006 and in the beginning of 2007. The subjects from the research were, in 2006, representative members of the main associations and corporations, besides the shrimp producers from the state, when the context of the activity was set. In the second phase, in 2007, representative members from the two cooperatives that were listed above were interviewed the president from Coopercam and the marketing manager from Unipesca. Besides these two members, directors from two important organizations in each of these cooperatives were also interviewed, giving out the necessary information for the research. Secondary data was also collected from the Brazilian Association of Crab producers website, as well as from news from important newspapers in RN, such as Tribuna do Norte. The primary data was analyzed in terms of quality, accordingly to the documental analysis technique. Thus, through the data that was collected, it can be concluded that the reasons that motivated the companies to cooperate can be explained in terms of the transactional costs economy. However, the choice of partners is more connected to aspects approached by the social embededness. When aspects related to development and evolution were analyzed, it could be seen that both aspects from TCE and Embededness were vital to explain the development of the cooperatives mentioned

A dinâmica do campo organizacional e a adoção de estratégias na carcinicultura do RN

This study aimed to understand the relations inside the organizational Structuring of the shrimp Field - the shrimp agribusiness placed in Rio Grande do Norte State and the strategies adopted by its players. In order to achieve that, semi-structured interviews were conducted with samples of various organizations that act in the field, like cooperatives, associations, enterprises of different links in the chain, universities and state agencies. The interviews built up a large collection of secondary data. As expected, it was found that Field and strategies are related in a recursive way: the configuration of the field, a result from his own biography, has decisively influenced the strategies adopted by its actors, who, as evolved, eventually caused further changes in the Field and outlines the plot of this area of interaction. It was found, for example, that after thirty-five years of its genesis, the Field of shrimp RN still has a low level of institutionalization, which helps to understand the difficulty of its actors in establish strategies based on partnerships and cooperation; Those actions are so necessary to alleviate the effects of the crisis that devastated the industry since 2004. It was noticed, however, that this level of institutionalization is a result, beside other factors, the very strategies that field actors are embracing along its trajectory. Thus, this study hopes to have contributed both to the necessary revival of the agency to institutional phenomenon, cited by Oliver (1991), and to meet the need for more contextualized approaches to organizational strategies (MINTZBERG, 1987; CLEGG, 2004; WHITTINGTON, 2004; 2006; SARAIVA and CARRIERI, 2007). It is an exploratory study that needs further investigation in order to get deep in this research. In this sense, others methodologies and theoretical perspectives need to be used, especially those relating to the seizure of the disputes and discursive aspects of power, as salient in the field investigated. Moreover, in terms of "practical actions", it is suggested that, as soon as possible, the main actors of the field (cooperatives, companies, and state entities in class) can be able of agglutinate efforts to support the shrimp field in RN State and make sustainable actions, which can promote the development of activity in a global view. On the apse of shrimp activities everybody wanted to be the "father of the child," Now, someone has to "stay in the goal."

A Geração de inovação na carcinicultura do RN: Uma análise a partir da imersão social

This dissertation examines the organizational innovation as a nonlinear process, which occurs in a social and political context and, therefore, socially immersed. Examines the case of shrimp in the state of RN, starting from the following problem: although the norteriograndense shrimp occupies the largest producer of farmed shrimp from Brazil, has a series of bottlenecks concerning the generation of industry innovation, concerning the social relationships and policies between the various actors in the network, whether private or public, and its consequences in terms of opportunity and limits generated for the innovative dynamics. The objective of the research is to understand how the social embeddedness of political actors affects norteriograndense shrimp within the context of structural relations, the industry generation of innovation, throughout its technological trajectory . The approach of social embeddedness balances atomised perspectives, undersocialized and oversocialized, of economic action, considering both the human capacity to act as sources of constraint, whose mechanisms are analyzed the structural and political. In methodological terms this is a case study, analyzed from the research literature, documentary and experimental. Primary data were collected through semi-structured interviews and analyzed in depth by the technique of content analysis. Was adopted a longitudinal approach, seeking to understand the phenomenon from the perspective of the subjects, describing it in an inductive process of investigation. After characterizing the sector and defining their technological trajectory, the analysis of the results followed its four stages: (1) Introduction of Technology: 1973-1980, (2) Intensification of Research: 1981-1991, (3) Technological Adaptation, 1992 -2003, (4) Technological Crisis: 2004-2009. A cross-sectional analysis along the evolutionary trajectory revealed the character of structural changes and policies over time, and implications on the generating process of innovation. Note that, the technological limit to which the sector reached requires changes in technology standards, but is more likely that the potiguar shrimp is entering a new phase of his career in technology rather than a new technological paradigm

Gestão de pessoas, fato administrativo e racionalidades: um estudo em uma ONG de Natal-RN

This present work aimed to investigate, through the structuring element Fato Administrativo , the way rationality guides the processes of personnel management at the Associação Companhia TerrAmar , which operates in the district of Felipe Camarão in Natal/RN. This paper is characterized by a descriptive study, as it sought to establish the relationship between the materialization of the studied phenomenon - by means of a theoretical framework consisting of the following theories: Fato Administrativo (GUERREIRO RAMOS, 1983), Substantive and Instrumental Rationality (GUERREIRO RAMOS, 1981) and Proceedings of Personnel Management proposed by Joel Dutra (2004). As the main research findings, time as an intrinsic element of the Fato Administrativo - suffers much interference from external factors, especially from the sponsors of the researched organization and also from their bureaucratic control tools; not directly relating to the processes of Personnel Management, though. Among these, it was noticed that there isn‟t a dialogue between the sponsors and the theory, due to incompatibilities regarding the structure and nature of each organization. Both movement and development have stood out. These are processes that are guided by elements of substantive rationality, literally speaking, including personal, emancipatory and solidarity values. Thus, it is stated that for future research a compatible model of Personnel Management should be built and explored (compatible with the nature of nonprofit organizations). Understanding, in depth, the processes separately aiming to understand each work is also advised. Trying to fully understand the ways of overcoming the lack of skilled workers to perform activities in similar organizations needs to be considered as well

Espaços de pobreza e mobilidade urbana: os deslocamentos da população de baixa renda em Natal/RN

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

Guardas prisionais, contextos de atuação e motivações

O contexto prisional tem recebido nos últimos anos uma grande atenção por parte dos investigadores portugueses. Porém, esse estudo não se têm centrado nos guardas prisionais, como grupo profissional. Dada a inexistência de pesquisas sobre esta temática, o presente estudo pretende analisar os contextos em que se desenrola o exercício das funções dos guardas prisionais, uma vez que estas podem produzir desmotivação e desgaste profissional nestes indivíduos. A investigação decorreu com a participação de guardas prisionais, a exercer funções nos Estabelecimentos Prisionais de Chaves, Lamego e Izeda. Para serem atingidos os objetivos propostos, optou-se pelo método qualitativo,através da aplicação de entrevistas semiestruturadas como instrumento de recolha de dados. Durante o mês de Abril e Maio de 2016 foram realizadas entrevistas a quinze guardas prisionais que trabalhavam em contacto direto com os reclusos. Ao longo da análise das entrevistas ficaram patentes nas declarações algumas fontes de desmotivação devido ao congelamento de salários e das progressões na função pública, à inexistência de concursos internos e à ineficácia e injustiça das avaliações de desempenho. Por outro lado, os profissionais estudados afirmam sentir uma fraca valorização das suas funções no serviço, a par de uma má imagem da sua profissão, difundida e sustentada pelos meios de comunicação social. Estes fatores podem contribuir para que eles próprios não se sintam identificados com o grupo profissional ao qual pertencem. Finalmente, os entrevistados manifestam sentir uma falta de formação contínua, cuja existência consideram fundamental.

Adaptação de cultivares diploides e tetraploides de azevém anual às condições climáticas do sudoeste do Paraná

Annual ryegrass is one of the species that best meets the needs of ranchers of southern Brazil during the winter period of the year. The breeding of ryegrass for many years has been developing superior materials, diploid and tetraploid, which, despite its higher prices for seed are being used by producers because of their better performance and quality. The objective of this research was to evaluate the behavior of different cultivars of Italian ryegrass - diploid and tetraploid, grazing, climate conditions of southwestern Paraná. The experiment was conducted in the city of Pato Branco / PR. The experimental design was a randomized block design with four replications. The observed cultivars were: LE 284, Camaro, Bakarat, Estações, Ponteio and Nibbio (diploid) and Winter Star, KLM 138, Escorpio, Titan, Barjumbo and Potro (tetraploid). The grazing was mob-grazing type time respecting input of 25 cm and 10 cm high output. It was observed that the cultivars that had high period of pasture use were those that produced larger amounts of forage. For all cultivars the highest forage accumulations occur between the months of August, September and October. Tetraploid have lower population density of tillers, but this does not affect the IAF among cultivars nor the interception of solar radiation before and after the completion of a grazing. NDF and ADF contents linearly increase with advancing in ryegrass cultivars development cycle. On average, tetraploid cultivars produce larger amounts of forage in relation to diploid cultivars.

Impact of natural and/or chemical stressors on the freeze-tolerant and euryhaline enchytraeid, Enchytraeus albidus

Rapid climatic changes are taking place in Arctic, subarctic and cold temperate regions, where predictions point to an increase in freeze-thaw events, changes in precipitation, evaporation and salinity patterns. Climate change may therefore result in large impacts in ecosystem functioning and dynamics, especially in the presence of contaminants due to intense anthropogenic activities. Even though multiple stress approaches have received increasing interest in the last decades, the number of such studies is limited. In particular, knowledge on the effect of freezethaw events and salinity fluctuations on ecotoxicology of soil invertebrates is lacking, especially important when considering supralittoral species. Therefore, the aim of this thesis was to investigate the effects of low temperature and salinity fluctuations, singly and in combination with contaminants, in the freeze-tolerant and euryhaline enchytraeid Enchytraeus albidus. The assessment of population level endpoints (survival and reproduction), along with physiological and biochemical parameters such as levels of cryoprotectants, ice/water content, oxidative stress biomarkers, cellular energy allocation, and tissue concentration of chemicals (when applied), provided new and valuable knowledge on the effects of selected physical and chemical stressors in E. albidus, and allowed the understanding of adjustments in the primary response mechanisms that enable worms to maintain homeostasis and survival in harsh environments such as polar and temperate-cold regions. The presence of moderate levels of salinity significantly increased freeze-tolerance (mainly evaluated as survival, cryoprotection and ice fraction) and reproduction of E. albidus. Moreover, it contributed to the readjustments of cryoprotectant levels, restoration of antioxidant levels and changed singnificantly the effect and uptake of chemicals (copper cadmium, carbendazim and 4-nonylphenol). Temperature fluctuations (simulated as daily freeze-thaw cycles, between -2ºC and -4ºC) caused substancial negative effect on survival of worms previsouly exposed to non-lethal concentrations of 4-nonylphenol, as compared with constant freezing (-4ºC) and control temperature (2ºC). The decrease in cryoprotectants, increase in energy consumption and the highest concentration of 4-nonylphenol in the tissues have highlighted the high energy requirements and level of toxicity experienced by worms exposed to the combined effect of contaminants and freezing-thawing events. The findings reported on this thesis demonstrate that natural (physical) and chemical stressors, singly or in combination, may alter the dynamics of E. albidus, affecting not only their survival and reproduction (and consequent presence/distribution) but also their physiological and biochemical adaptations. These alterations may lead to severe consequences for the functioning of the ecosystems along the Arctic, subarctic and cold temperate regions, where they play an important role for decomposition of dead organic matter. This thesis provides a scientific basis for improving the setting of safety factors for natural soil ecosystems, and to underline the integration of similar investigations in ecotoxicology, and eventually in risk assessment of contaminants.

A economia argentina no final do século XX : crise, autral e plano de conversibilidade

O presente trabalho tem como finalidade analisar a história econômica da Argentina no final do século XX, após o regime militar, através de uma síntese do modelo econômico argentino com foco nos Planos Austral e de Conversibilidade. Para tanto, utilizou-se uma pesquisa qualitativa, exploratória, histórica, explicativa e bibliográfica. Os estudos acentuam um caráter nitidamente anti-inflacionário do Plano Austral, que se assentava basicamente no congelamento dos preços, salários e câmbio, enquanto que o Plano de Convertibilidade atrelava a moeda local ao dólar americano. Contudo, os dois planos econômicos não conseguiram resolver os graves problemas da economia Argentina no longo prazo, embora o segundo tenha tido uma sobre vida mais longa, entretanto, a custa de um endividamento profundo. Durante uma década de existência o Plano de Conversibilidade passou por diversas fases e causou uma série de efeitos para economia Argentina, com consequências que foram sentidas inclusive nos primeiros anos do século XXI.

Estudo comparativo de dois tipos de cultivo: monocultivo (camarões) versus cultivo integrado (algas/camarões)

The integrated culture of seaweed and aquatic animals is an ancient practice in Asian countries. The expansion of this practice to western countries is consequence of the recognition of this system as a sustainable alternative that allows economical diversification and mitigation of environmental impacts generated by effluents of aquaculture. This study evaluated the growth of the seaweed Gracilaria caudata and of the shrimp Litopenaeus vannamei in monoculture (shrimps) and integrated culture (shrimps and algae) systems, and accessed the effect of the seaweed in the water quality. There were two treatments in the experiment: monoculture (shrimps) and integrated culture (shrimps/ algae). The organisms were cultured in 6 aquaria (10L) filled with seawater (35.0±0.0 PSU and 28.1±0.4°C) for 28 days. The nutrients of water (PO43-, NH4+, NO2-, NO3- and DIN), the biomass and the relative growth rate (RGR, % day-1) of seaweed and shrimps were measured weekly. The parameters pH, temperature, salinity and dissolved oxygen were measured daily. The concentration of NH4+ in integrated culture (62.8±25.2µM) was lower (Mann-Whitney p<0.001) than in monoculture (85.6±24.3µM). The mean of PO4- in monoculture (10.4±4.6µM) was markedly higher (Mann-Whitney; p=0.024) than that in integrated culture (8.7±4.1µM). The level of dissolved oxygen in integrated culture (6.0±0.6mg/L) was higher (t-Student; P=0.014) than that in shrimp monoculture (5.8±0.6mg/L). The mean values of the parameters pH, NO2-, NO3- and DIN were 7.5±0.2, 10.1±12.2µM, 24.5±3.2µM and 120.17±30.76µM in monoculture, and 7.5±0.2, 10.5±13.2µM, 27.4±3.5µM and 100.76±49.59µM in integrated culture. There were not differences in these parameters between treatments. The biomass and RGR of seaweed reached 15.0±1.9g and 7.4±2.8% day-1 at the end of the experiment. The performance of shrimp was favorable in monoculture (1.5±0.8g; 5.7±1.6% dia-1) and in integrated culture (1.5±0.7g; 5.2±1.2% dia-1), and the rate of survival was 100% in both treatments. The tolerance and favorable performance of Gracilaria caudata suggest that this seaweed might be integrated into shrimp (Litopenaeus vannamei) culture systems

Recuperação de carotenóides microbianos por diferentes técnicas de ruptura celular

O objetivo deste trabalho foi utilizar diferentes técnicas químicas (dimetilsulfóxido, ácido clorídrico, acético e lático), técnicas mecânicas (banho ultrassônico, abrasão com pérolas de vidro, maceração com terra diatomácea, ruptor ultrassônico e imersão em nitrogênio líquido) e técnica enzimática (preparado enzimático comercial Glucanex®) para a recuperação de carotenoides a partir da ruptura da parede celular das leveduras Sporidiobolus pararoseus e Rhodotorula mucilaginosa isoladas de amostras ambientais. Para isso a obtenção de biomassa foi realizada através de cultivos submersos no meio YM, a 25 °C, 180 rpm por 168 h. Para a ruptura celular, a operação de congelamento da biomassa (-18°C por 48 h) foi estudada. Os métodos de secagem convencional por ar forçado (35°C/48h) e liofilização (-80°C/48h, em ultrafreezer, seguido de liofilizador até alcançar 2% de umidade da amostra) também foram avaliados. Nas técnicas químicas aplicadas, o dimetilsulfóxido apresentou os melhores resultados para as duas leveduras, porém o seu uso é limitado devido a sua toxicidade. Para S. pararoseus, os maiores valores encontrados foram para o ácido clorídrico, seguido do acético e do lático, sendo detectada diferença entre eles quando aplicado o congelamento. Com R. mucilaginosa, os maiores valores foram encontrados para os ácidos acético e lático, seguido do ácido clorídrico, no qual o congelamento da biomassa também não influenciou a recuperação dos carotenoides. Dentre as técnicas mecânicas estudadas, para a levedura S. pararoseus, o banho ultrassônico e a abrasão com pérolas de vidro apresentaram os resultados mais promissores comparados ao DMSO (84,79±2,34 e 76,87±2,06 μg/g respectivamente), onde o processo de congelamento da biomassa não influenciou positivamente no percentual de extratibilidade e na concentração específica dos carotenoides quando utilizada estas técnicas. Com Rhodotorula mucilaginosa, o banho ultrassônico propiciou a recuperação da maior concentração específica de carotenoides (193,5±25,8 μg/g), sendo que o processo de congelamento também não influenciou positivamente no percentual de extratibilidade e na concentração específica dos carotenoides. Através do Delineamento Central Composto Rotacional (DCCR) 23 foi possível avaliar que a levedura S. pararoseus não demonstrou nenhum efeito sob as variáveis pH, temperatura e concentração de enzima. Assim, a melhor condição de trabalho escolhida foi pH 7,4, 30 ºC e concentração de enzima de 1,0 g/gcs, onde apresentou a concentração específica de 42,6 μg/g e volumétrica de 308 μg/L de carotenoides. Para R. mucilaginosa, a condição ótima foi definida como 1,0 g/gcs, pH 5,0 e temperatura de 30 ºC, onde foi encontrado 115,1±8,1 μg/g e 470,1±38,8 μg/L para a concentração específica e volumétrica de carotenoides, respectivamente. A utilização de técnicas combinadas empregando banho ultrassônico e lise enzimática não proporcionou melhorias nos resultados para ambas as leveduras. A liofilização provocou um ganho de 20% e 13,7% na concentração específica dos carotenoides das leveduras S. pararoseus e R. mucilaginosa, respectivamente, onde o congelamento da biomassa não influenciou significativamente (p<0,05) a recuperação de carotenoides provenientes das duas leveduras, podendo ser eliminada do processo. Assim, para S. pararoseus o banho ultrassônico e as pérolas de vidro apresentaram os melhores resultados na recuperação de carotenoides, e para R. mucilaginosa o melhor resultado foi alcançado com o banho ultrassônico.

Caracterização do estoque de anchoita (engraulis anchoita) da região Sul do Brasil e utilização desta matéria-prima na elaboração de produto de alto valor agregado

O trabalho teve por objetivo caracterizar o estoque de anchoita (Engraulis anchoita) capturado na região sul do Brasil, visando à utilização deste recurso de alto valor biológico no desenvolvimento de produtos semi-prontos e de fácil preparo, tipo empanado. Os experimentos foram conduzidos com anchoita resultante de cruzeiros realizados pelo Navio Oceanográfico Atlântico Sul da Universidade Federal do Rio Grande (FURG), RS, Brasil. Os exemplares foram capturados entre a cidade de Rio Grande (32ºS, RS-Brasil) e 51ºW. Após captura, o pescado foi armazenado a bordo em mistura de gelo e água do mar, na razão 1:1. As amostras foram transportadas para o laboratório de Biotecnologia da FURG e mantidas sob congelamento a -18°C, até a realização das análises. O trabalho está constituído por uma revisão bibliográfica, que enfatiza a importância do recurso pesqueiro em estudo como potencial a ser explorado, discorre sobre ácidos graxos e perfil de voláteis, bem como, o desenvolvimento de produtos à base de pescado. O desenvolvimento do trabalho é expresso por quatro artigos. O primeiro teve como objetivo caracterizar o estoque de anchoita segundo a biometria, rendimento, composição proximal, compostos nitrogenados e ácidos graxos. O rendimento, a composição proximal e o perfil de ácidos graxos foram realizados nas três frações que compõe o peixe: músculo claro, escuro e vísceras. A análise dos resultados demonstrou a variabilidade dos componentes em função das frações avaliadas e da época de captura, o que pode contribuir para a escolha do processo tecnológico a ser aplicado no desenvolvimento de produtos de alto valor agregado a partir dessa matéria-prima. No segundo artigo foi determinado o perfil de ácidos graxos da anchoita e avaliado o comportamento destes compostos durante o armazenamento congelado, bem como, dos voláteis gerados. Os resultados demonstraram a influência do armazenamento na modificação dos ácidos graxos, em especial, EPA e DHA, e que os voláteis gerados podem ser um índice em potencial para avaliar a qualidade da anchoita congelada. No terceiro artigo objetivou-se selecionar e treinar julgadores para avaliação do odor a pescado utilizando os padrões referência obtidos a partir do perfil de voláteis. Neste sentido, foi levantada a terminologia que descreve o odor da anchoita, definido padrões referência, bem como, selecionado e treinado uma equipe de julgadores. Foram utilizados 20 candidatos, deste total, 9 foram selecionados pelo método das amplitudes. Os julgadores selecionados foram submetidos ao treinamento no uso de escala não estruturada e na avaliação da intensidade do odor a pescado. O desempenho dos julgadores foi definido utilizando como amostra solução de lavagem resultante do processo de obtenção de base protéica de anchoita. Os resultados foram avaliados com base no poder de discriminação, repetibilidade das respostas e concordância entre julgadores, segundo análise de variância, com duas fontes de variação (amostra e repetições). Foram obtidos os valores de Famostra e Frepetição, para cada julgador. Os julgadores com o valor de Famostra significativo (p≤0,30) e Frepetição não significativo (p>0,05), bem como, concordância de médias com os demais julgadores foram considerados treinados. Segundo esse processo a equipe foi constituída por 8 julgadores selecionados e treinados na avaliação do odor a pescado. Finalmente, no quarto artigo foi avaliada a possibilidade de uso de base protéica (BPP) de anchoita na elaboração de massa base de empanados, bem como, em substituição a farinha de cobertura. Para obtenção das BPPs, foram testadas duas soluções extratoras (3 ciclos de extração com ácido fosfórico 0,05% e 1 ciclo de ácido fosfórico seguido de 2 ciclos com água). A BPP obtida na melhor condição utilizada foi seca a 70°C e submetida ao processo de moagem em moinho de facas para ser utilizada como farinha de cobertura. Formulações de empanado utilizando diferentes concentrações (25, 50, 75 e 100%) de anchoita desidratada na cobertura foram testadas no produto frito e forneado. Um teste de preferência com consumidores em potencial foi aplicado às diferentes formulações. Os resultados indicaram que a melhor condição de lavagem para obtenção das BPPs testadas foi quando são utilizados 3 ciclos de extração com ácido fosfórico. A avaliação da preferência junto ao consumidor em potencial demonstrou que a anchoita desidratada pode ser utilizada como farinha de cobertura em empanados na concentração de até 75%.
