Relações interorganizacionais e confiança no setor da carcinicultura: um estudo de caso na camanor produtos marinhos

This study investigated how the types of confidence based on competence and good will act in the formation and maintenance of cooperation relationships between the Camanor and its partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). It used organizational approaches on networks based primarily on studies of Powell (1987, 1990), Das and Teng (2000, 2001), Child (2001) and Contractor and Lorange (2004) which have described the advantages that cooperative relationships can provide, as well as their limits as alternative governance structures. Confidence has been considered an important factor affecting the actions and development of organizations involved in networks or in strategic alliances (ZAHEER; HARRIS, 2006) and is the most appropriate control mechanism in these situations (SYDOW, 1998). Confidence is seen from two different approaches: the economic and the sociological (ZAHEER; HARRIS, 2006). To facilitate the understanding of confidence some typologies have been created, as proposed by Barney and Hansen (1994), Lane (1998), Das and Teng (2000), Child (2001) and Wever, Martens and Vandenbempt (2005). This study made use of the case study as proposition of Yin (2005). Semi-structured interviews were held with pre-determined routes, in a single stage performed in early 2008. The research subjects were owners and / or responsible for Camanor and its business partners (Aquatec, Purina, Caçuá, Uvifrios and Malta / Cleyton). Also secondary data were collected in several sites related to the industry and enterprises studied, in addition to data collected by previous studies conducted by CARCINEREDES (2006). The primary data were analyzed using the analysing technique of the content proposed by Bardin (1994). Regarding the secondary data, they were qualitatively analyzed according to documentary analysis technique (BARDIN, 1994). Thus, through the data collected, could be concluded that although there is confidence based on good faith in relationships(UZZI, 1998; OF; TENG, 2001), their presence does not determine the formation and / or maintenance of a partnership, serves only in order to facilitate the relationship, making them more flexible. The confidence based on competence (DAS; TENG, 2001) influenced the formation and maintenance of relations studied. Because whether or not to form a relationship with another organization it is used the perception of the partner acts, namely the reputation (image) as decision basis. And it is through the verification of the performance of the partner activities that will determine the continuation of the partnership

Influência dos intermediários de distribuição de produtos turísticos no processo de decisão do meio de hospedagem pelo consumidor

This study examines the complex hotel buyer decision process in front of the tourism distribution channels. Its objective is to describe the influence level of the tourism marketing intermediaries, mainly the travel agents and tour operators, over the hotel decision process by the buyer-tourist. The data collection process was done trough a survey with three hundred brazilian tourists hosted in nineteen hotels of Natal, capital of Rio Grande do Norte, Brazil. The data analysis was done using some multivariate statistic techniques as correlation analysis, multiple regression analysis, factor analysis and multiple discriminant analysis. The research characterizes the hotel services consumers profile and his trip, and identifying the distribution channels used by them. Furthermore, the research verifies the intermediaries influence exercised over hotel buyer decision process, looking for identify causality relations between the influence level and the buyer profile. Verifies that information about hotels available on internet reduces the probability that this influence can be practiced; however it was possible identifying those consumers considers this information complementary and non-substitutes than the information from intermediaries. The characteristics of the data do not allow indentifying the factors that constraint the intermediaries influence neither identifying discriminant functions of the specific distribution channel choice by consumers. The study concludes that consumers don t agree in have been influenced by intermediaries or don t know if they have, still considering important to consult them and internet doesn t substitute their function as information source

Efeito da velocidade de aquecimento nas propriedades de produtos da cerâmica estrutural

Heating rate is one of the main variables that determine a fire cycle. In industrial processes that use high temperatures, greater fire great can reduce the cost of production and increase productivity. The use of faster and more efficient fire cycles has been little investigated by the structural ceramic industry in Brazil. However, one of the possibilities that aims at modernizing the sector is the use of roller kilns and the inclusion of natural gas as fuel. Thus, the purpose of this study is to investigate the effect of heating rate on the technological properties of structural ceramic products. Clay raw materials from the main ceramic industries in the state of Rio Grande do Norte were characterized. Some of the raw materials characterized were formulated to obtain the best physical and mechanical properties. Next, raw materials and formulations were selected to study the influence of heating rate on the final properties of the ceramic materials. The samples were shaped by pressing and extrusion and submitted to rates of 1 °C/min, 10 °C/min and 20 °C/min, with final temperatures of 850 °C, 950 °C and 1050 °C. Discontinuous cycles with rates of 10 °C/min or 15 °C/min up to 600 °C and a rate of 20 °C/min up to final temperature were also investigated. Technological properties were determined for all the samples and microstructural analysis was carried out under a number of fire conditions. Results indicate that faster and more efficient fire cycles than those currently in practice could be used, limiting only some clay doughs to certain fire conditions. The best results were obtained for the samples submitted to slow cycles up to 600 °C and fast fire sinterization up to 950 °C. This paper presents for the first time the use of a fast fire rate for raw materials and clay formulations and seeks to determine ideal dough and processing conditions for using shorter fire times, thus enabling the use of roller kilns and natural gas in structural ceramic industries

Avaliação de produtos naturais no controle de biofilmes formados em sistema dinâmico

The biofilms microbial forms of association are responsible for generating, accelerating and / or induce the process of corrosion. The damage generated in the petroleum industry for this type of corrosion is significatives, representing major investment for your control. The aim of this study was to evaluate such tests antibiograms the effects of extracts of Jatropha curcas and essential oil of Lippia gracilis Schauer on microrganisms isolated from water samples and, thereafter, select the most effective natural product for further evaluation of biofilms formed in dynamic system. Extracts of J. curcas were not efficient on the complete inhibition of microbial growth in tests type antibiogram, and essential oil of L. gracilis Schauer most effective and determined for the other tests. A standard concentration of essential oil of 20 μL was chosen and established for the evaluation of the biofilms and the rate of corrosion. The biocide effect was determined by microbial counts of five types of microorganisms: aerobic bacteria, precipitating iron, total anaerobic, sulphate reducers (BRS) and fungi. The rate of corrosion was measured by loss of mass. Molecular identification and scanning electron microscopy (SEM) were performed. The data showed reduction to zero of the most probable number (MPN) of bacteria precipitating iron and BRS from 115 and 113 minutes of contact, respectively. There was also inhibited in fungi, reducing to zero the rate of colony-forming units (CFU) from 74 minutes of exposure. However, for aerobic and anaerobic bacteria there was no significant difference in the time of exposure to the essential oil, remaining constant. The rate of corrosion was also influenced by the presence of oil. The essential oil of L. gracilis was shown to be potentially effective

Efeito de preparações de produtos naturais (cravo da índia e tomate) e de um produto sintético na marcação de constituintes sangüineos com tecnécio-99m e na morfologia de hemácias isoladas de sangue de ratos wistar

There are strong interests in the evaluation of the biological effects of natural and synthetic products. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this work was to study the effects of Clove (Caryophyllus aromaticas L.) and OZE (preparation used in the Health Sciences) on the labeling blood constituents with 99mTc and on the morphologic red blood cells (RBC) and the action of an extract of tomato (TO) on the labeling of blood constituents Blood samples were incubated with clove or OZE or TO, stannous chloride and 99mTc. Plasma (P), blood cells (BC), insoluble fractions (IF) of plasma and blood cells were separated. The radioactivity was counted and percentage of radioactivity (%ATI) to each blood fraction was calculated. The shape and morphometric parameter (perimeter/area ratio) were evaluated in the studies with clove and OZE. Clove extract and OZE altered significantly (p<0.05) the %ATI of blood constituents and the shape of red blood cells. However, clove extract not altered the red blood cells perimeter/area ratio. The tomato extract used at the highest concentrations reduced significantly (p<0.05) the %ATI in IF-P, although this extract did not modify the radiolabeling on BC, neither the radioactivity fixation on IFBC. The results indicate that these chemical compounds would have oxidative/chelating actions

Avaliação in vitro da eficácia de produtos homeopáticos contendo momordica charantia através de bioensaios

Homeopathic medicines have been used for over two hundred years without the examination of their effects on in vivo and in vitro assays, due to the peculiarity of homeopathic preparations, the high dilution, which creates a challenge for the use of usual analytical techniques of quality control of medicine.Although there is scarcity of literature and variety of experiments, recently there have been some studies with few in vitro assays which have shown positive responses when evaluating the mechanism of action of homeopathic medicines which are able to act on a specific system.The present study aims to evaluate the efficacy of homeopathic products containing Momordica charantia through bioassays.Homeopathic products were tested by the MTT to assess cytotoxicity in RAW 264.7 (macrophage-like cells) and in tumor cells HeLa (human cervical adenocarcinoma cells), CHO K1 (Chinese hamster ovary cells), PANC-1 (human pancreas cancer cells) and PC-3 (human prostate cancer cells), dosage of inflammatory mediators NO, TNF-α and IL-6 released by RAW 264.7 cells, analysis of the death process and cell cycle changes of PC-3 by flow cytometry. The data demonstrate that homeopathic products of Momordica charantia did not show cytotoxicity to RAW 264.7, increased the production of inflammatory mediators by RAW 264.7 synergistically with LPS, showed cytotoxicity to PC-3 with change in its cell cycle inhibiting its proliferation, being the 30CH the most potent sample. Correlation studies were conducted in order to evaluate the possible in vitro applicable models to the quality control of homeopathic products with Momordica charantia. The data showed that the best applicable models in assessing the quality are the MTT to assess cytotoxicity in RAW 264.7 and PC-3 in 24 hours for Momordica charantia fruit products and dosage of NO production by RAW 264.7 with and without LPS

Contribuições sobre estudos térmicos (TG/DTG, DTA, DSC e DSC-Fotovisual) da rifampicina e seus principais produtos de degradação

Since its synthesis over 48 years rifampicin has been extensively studied. The literature reports the characterization of thermal events for rifampicin in nitrogen atmosphere, however, no characterization in synthetic air atmosphere. This paper aims to contribute to the thermal study of rifampicin through thermal (TG / DTG, DTA, DSC and DSC - FOTOVISUAL ) and non-thermal (HPLC, XRPD , IR - FTIR , PCA) and its main degradation products ( rifampicin quinone , rifampicin N-oxide 3- formylrifamicin). Rifampicin study was characterized as polymorph form II from techniques DSC, IR and XRPD. TG curves for rifampicin in synthetic air atmosphere showed higher thermal stability than those in N2, when analyzed Ti and Ea. There was characterized as overlapping events melting and recrystallization under N2 with weight loss in the TG curve, suggesting concomitant decomposition. Images DSCFotovisual showed no fusion event and showed darkening of the sample during analysis. The DTA curve in synthetic air atmosphere was visually different from DTA and DSC curves under N2, suggesting the absence of recrystallization and melting or presence only decomposition. The IV - FTIR analysis along with PCA analysis and HPLC and thermal data suggest that rifampicin for their fusion is concomitant decomposition of the sample in N2 and fusion events and recrystallization do not occur in synthetic air atmosphere. Decomposition products studied in an air atmosphere showed no melting event and presented simultaneously to the decomposition initiation of heating after process loss of water and / or solvent, varying the Ti initiating events. The Coats - Redfern , Madsudhanan , Van Krevelen and Herwitz - Mertzger kinetic parameters for samples , through the methods of OZAWA , in an atmosphere of synthetic air and / or N2 rifampicin proved more stable than its degradation products . The kinetic data showed good correlation between the different models employed. In this way we contribute to obtaining information that may assist studies of pharmaceutical compatibility and stability of substances

Cinematografando o consumo :as narrativas e práticas culturais dos clientes de videolocadoras de Natal (RN)

The present work is an exercise of analysis of cultural practices related to movie consume by the clients of video rental stores in Natal city (Rio Grande do Norte, Brazil). With sociology of practice as support, especially that one which develops from the seminal works of Anthony Giddens and Pierre Bourdieu, we have searched, from the apprehension of the narratives build up by these actors from the movies they attend, to point the way they build exercises of reflexivity and creativity in the reception of works commonly identified as products of the so called mass culture . This path allows us, in the steps of Nestor Garcia Canclini, researcher in reception within Latin-American context, create and, somehow confirm the hypothesis that consume is also useful for thinking . In order to get to this result, we have carried out a camp research that used instruments and techniques both quantitative and qualitative. After the data analysis we came to the conclusion that consume of movies taken as commercial type and as not very noble in the environment of cultural production, also impels exercises of creativity and social reflexivity

Indústria cultural e forró eletrônico no Rio Grande do Norte

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

Toxicidade diferencial de produtos à base de abamectina ao ácaro Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) em citros

O ácaro Brevipalpus phoenicis é uma das principais pragas dos citros por ser vetor do Citrus Leprosis Virus (CiLV), agente causal da leprose, uma das mais graves doenças da citricultura. Objetivou-se avaliar o efeito tóxico de produtos à base de abamectina sobre o ácaro B. phoenicis. Foram realizados um experimento de ação direta e três de ação residual no Laboratório de Acarologia do Departamento de Proteção de Plantas (Fitossanidade) da FCAV - UNESP, Jaboticabal-SP. O delineamento adotado nos bioensaios foi o inteiramente casualizado, onde 10 tratamentos foram repetidos 7 vezes, sendo cada repetição composta por um fruto de laranja. Os tratamentos estudados (mL p.c./100 L de água) foram: Acaramik a 20; 30; 40 e 50 mL; Vertimec a 30 e 40 mL; Abamectin Nortox a 30 e 40 mL; Tricofol a 77 mL e uma testemunha sem aplicação. Utilizaram-se frutos com presença de verrugose, que foram lavados e parcialmente parafinados, deixando-se uma área sem parafina, que foi circundada com cola entomológica para contenção dos ácaros. Transferiram-se 20 ácaros adultos B. phoenicis para cada fruto. No bioensaio de ação direta, a transferência foi realizada antes das aplicações e, nos bioensaios de ação residual, aos 5; 10 e 15 dias após a aplicação dos produtos. A aplicação dos produtos sobre os frutos foi realizada em Torre de Potter. Os resultados obtidos nos bioensaios evidenciaram que os melhores tratamentos foram: Tricofol a 77 mL, Acaramik a 40 e 50 mL e Vertimec a 40 mL. de forma geral, os produtos testados podem ser utilizados no controle do ácaro B. phoenicis.

Avaliação de doses e produtos corretores da acidez em variáveis biométricas na produção de mudas de maracujazeiro

A utilização de produtos corretores da acidez do solo e a crescente busca por novos insumos agrícolas são de suma importância para uma agricultura sustentável e ecologicamente viável. O presente trabalho foi conduzido no viveiro de mudas do Setor de Fruticultura da Universidade Federal de Lavras (UFLA), Lavras, Estado de Minas Gerais. O delineamento experimental utilizado foi blocos casualizados em esquema fatorial 3 x 4, sendo três produtos, quatro doses e três repetições, as doses foram calculadas de modo que se atingisse a saturação estabelecida, de acordo com a concentração de cada produto. As doses foram: zero, metade, completa e o dobro da dose recomendada. A incubação foi realizada para o silício e calcário, e o Lithothamnium, pela liberação rápida, foi apenas incorporado ao solo. As características avaliadas foram: crescimento da parte aérea (mm), tamanho do sistema radicular (mm), número de folhas, matéria seca da parte aérea (mg), matéria seca da raiz (mg) e matéria seca total (mg). Os três produtos em questão proporcionaram mudas de qualidade, sendo a dose de 1,4 vezes a recomendada, a melhor para formação de mudas de maracujazeiro.

Avaliação física e química de produtos minimamente processados de abacaxi-'Pérola'

O objetivo deste trabalho foi avaliar, física e quimicamente, produtos minimamente processados de abacaxi-'Pérola', rodelas e metades, armazenados sob diferentes temperaturas (3ºC, 6ºC e 9ºC). Frutos selecionados, quanto ao grau de maturação e ausência de danos, foram lavados, desinfeccionados com cloro (200 mg.L-1) e armazenados a 10ºC, por 12 horas, antes do processamento. O produto minimamente processado foi embalado em bandejas de isopor recobertas com filme de PVC esticável (metades) ou bandejas de tereftalato de polietileno (rodelas) e armazenado sob refrigeraç ;ão, com avaliação a cada 3 dias, quanto à textura, coloração, pH, e conteúdos de sólidos solúveis totais, acidez total titulável, ácido ascórbico e de açúcares, solúveis e redutores. Durante o armazenamento, o produto tornou-se menos firme, e sua polpa apresentou escurecimento. Os conteúdos de açúcares solúveis e redutores e de sólidos solúveis totais não foram afetados pelo tipo de preparo, temperatura ou embalagem. Os teores de acidez total titulável aumentaram e foram influenciados pela temperatura, sendo que os mantidos a 9ºC apresentaram os maiores teores, havendo, como conseqüência, decréscimo no pH. Os produtos armazenados a 9ºC também apresentaram evolução mais rápida no escurecimento, na redução do teor de ácido ascórbico e menor vida útil (6 dias), enquanto, para os armazenados a 3ºC e 6ºC, este período foi de 9 dias. Os resultados obtidos permitiram concluir que a temperatura de armazenamento foi o fator limitante para a vida útil destes produtos.
