Abstract: Since amateur fishing in fishponds has been on the increase in Brazil, there is a great concern on the microbiological quality of fish. One hundred and thirty-eight samples were collected during the dry and rainy periods in ten fish farms. Aeromonas spp. counts and tests for sensitiveness to antimicrobials were performed, coupled to the physical and chemical analyses of water. Tests revealed that 70% of samples were contaminated by Aeromonas spp., with water averaging 2.92 Log CFU/100 mL during the rainy period and 3.16 Log CFU/100 mL during the dry one. Fish contaminated by Aeromonas spp. averaged 2.58 Log CFU/100 mL during the rainy period and 3.53 Log CFU/100 mL during the dry one. Aeromonas spp. samples were multi-resistant to 2 or 8 antimicrobials in 62.5% of the samples. Ampicillin was the antimicrobial with the highest resistance percentage rate. Results showed that fish bred in amateur fish farms constituted a health risk for the population.

Food and Nutrition Sciences (FNS) , 2017, DOI: 10.4236/fns.2017.811075
Abstract:
Hygiene-sanitary conditions, the presence of Salmonella spp. and indicator microorganisms of chicken cuts sold on the market in the Rec?ncavo da Bahia area, are analyzed and their co-relationship with conditions of commercialization is verified. Sixty samples were collected between May and August 2016 at informal selling sites (fairs, butcher shops, abattoirs) and in supermarkets of ten municipalities of the Rec?ncavo da Bahia region. Hygiene and sanitary conditions were assessed through a check list. Total coliforms, Escherichia coli, mesophylls, psychrotrophic organisms, molds and yeast, and Salmonella spp. were counted. Results revealed statistical difference for total coliforms and Escherichia coli only, featuring greater concentration rates in fairs, butcher shops and abattoirs. Further, 31.7% of samples indicated 31.7% Salmonella spp. and 16.6% of samples failed to comply with sanitary legislation on Escherichia coli. Observational analysis demonstrated that 61.83% and 38.1% of the samples respectively on informal sites and in supermarkets did not comply with legislation and indicated a co-relationship of some variables with the growth of total coliforms, Escherichia coli and mesophylls. Pathogenic and indicator microorganisms suggest flaws in hygiene and sanitary conditions in the commercialization of chicken cuts and health risks to consumers.

Abstract: High nutritional content coupled with low cost and ease of purchase justifies the frequent use of chicken eggs. Even with technological innovations in the production, storage, and distribution of eggs, food poisoning continues to occur. Therefore, in the present study, we 1) evaluated the microbiological profile and the hygienic and sanitary quality of eggs commercialized in town fairs and markets and 2) verified whether there is any correlation between microbiological results and commercialization conditions. Thirty-six samples were collected from six municipalities in the region of Rec?ncavo from Bahia, Brazil. The hygienic and sanitary conditions were analyzed by quantifying the total coliforms, E. coli, mesophilic and psychrotrophic microorganisms, molds, and yeasts, and by the presence of Salmonella sp. The observational analysis showed that 91% and 68% of the samples in town fairs and markets, respectively, did not comply with the requirements of the current Brazilian legislation. There was no significant difference in the microbiological profile among samples from the fairs and markets. Several samples presented relevant significant values, indicating inadequate hygienic conditions and fecal contamination. Salmonella sp. was found in one sample. There was co-relationship between microorganism count and the variables “external dirt”, “external stains”, and “closeness to other products”, with high concentrations of total coliforms and E. coli in the non-conforming samples. Although no limits exist for mold and yeast counts, the presence of fungi makes the product unfit for consumption. Thus, the commercialization of eggs would benefit from more attention and supervision by the relevant authorities.

Abstract: O objetivo deste trabalho é avaliar a percep o dos consumidores em rela o à marca das principais institui es bancárias brasileiras (Bradesco, Itaú, Banco do Brasil e Unibanco), e como influenciam o processo de decis o do consumidor. O assunto percep o dos consumidores em rela o às marcas é importante no auxilio das institui es bancárias para compreender melhor seus clientes desenvolvendo uma estratégia mais eficaz. Compreender a marca como um ativo tangível e intangível é considerado como um fator relevante para a constru o de um diferencial competitivo. O método seguiu orienta o positivista e é quantitativo exploratório. A amostra de conveniência colhida de modo aleatório por 100 (cem) consumidores. Os resultados indicam que os consumidores acreditam que a coerência entre os produtos e servi os dos bancos em rela o à propaganda divulgada, também demonstrou que os consumidores acham importante a propaganda para a imagem da marca da institui o bancária, da mesma forma indica que levam em considera o o nome do banco antes de solicitar seus produtos e servi os. The objective of this study is to assess the consumers' brand perception of the main Brazilian banks (Bradesco, Itaú, Unibanco and Banco do Brasil), and its influence on the decision of the consumer. The issue of consumer perception on brand is important in support of banking institutions to better understand their customers by developing a more effective strategy. Understand the mark as a tangible and intangible assets is considered as a relevant factor to building a competitive differential. The method followed is quantitative and positivist orientation exploratory. A convenience sample collected from a random 100 (one hundred) consumers. The results indicate that consumers believe that the consistency between the products and services of banks in relation to the propaganda disseminated, also showed that consumers find important propaganda for the brand image of the bank, the same way indicates that take into account the name of the bank before requesting their products and services.
Lower critical field and intragrain critical current density in the ruthenate-cuprate RuSr$_{2}$Gd$_{1.5}$Ce$_{0.5}$Cu$_{2}$O$_{10}$

Physics , 2005, DOI: 10.1140/epjb/e2006-00043-y
Abstract: The lower critical field of the grains, $H_{c1}$, and the intragrain critical current density, $J_{c}$, were determined for the superconducting ruthenate-cuprate RuSr$_{2}$Gd$_{1.5}$Ce$_{0.5}$Cu$_{2}$O$_{10-\delta}$ [Ru-1222(Gd)] through a systematic study of the hysteresis in magnetoresistance loops. A reliable method, based on the effects of the magnetization of the grains on the net local field at the intergranular junctions is provided, circumventing the problem of the strong masking of the superconducting diamagnetic signal by the ferromagnetic background. The temperature dependency of $H_{c1}$ and $J_{c}$ both exhibit a smooth increase on cooling without saturation down to $T/T_{SC}$ $\cong $ 0.2. The obtained $H_{c1}$ values vary between 150 and 1500 Oe in the 0.2 $\leq $ $% T/T_{SC}$ $\leq $ 0.4 interval, for samples annealed in an oxygen flow; oxygenation under high pressure (50 atm) leads to a further increase. These values are much larger than the previously reported rough assessments (25-50 Oe), using conventional magnetization measurements. High $J_{c}$ values of $% \sim $ 10$^{7}$ A/cm$^{2}$, comparable to the high-T$_{c}$ cuprates, were obtained. The $H_{c1}(T)$ and $J_{c}(T)$ dependencies are explained in the context of a magnetic phase separation scenario.
Intergranular pinning potential and critical current in the magnetic superconductor RuSr2Gd1.5Ce0.5Cu2O10

Physics , 2004, DOI: 10.1103/PhysRevB.71.064520
Abstract: The intergranular pinning potential U and the critical current density Jc for polycrystalline RuSr2Gd1.5Ce0.5Cu2O10 ruthenate-cuprate were determined at zero magnetic field and temperature through the frequency shift in the peak of the imaginary part of the ac magnetic susceptibility, X". A critical state model, including a flux creep term, was found to accurately describe the X" behavior. The obtained values, U(H=0,T=0) ~ 30 meV and Jc(H=0,T=0) ~ 110 A/cm^2 are about two orders of magnitude and four times lower, respectively, in comparison with the high-Tc cuprate YBa2Cu3O7. These results were ascribed to the effects of the Ru magnetization on the connectivity of the weak-linked network, giving an intrinsic local field at the junctions of ~ 15 Oe. The impact on Jc is less intense because of the small average grain radius (~1 micrometer). The intragranular London penetration length at T = 0, [lambda_L(0) ~ 2 micrometer], was derived using a Kim-type expression for the field dependence of Jc. A possible source for the large value of lambda_L in comparison to the high-Tc cuprates is suggested to come from a strong intragrain granularity, due to structural domains of coherent rotated RuO6 octahedra separated by antiphase boundaries.
