Avaliação, identificação e atividade enzimática de bactérias psicotróficas presentes no leite cru refrigerado

Extended storage of refrigerated milk can lead to reduced quality of raw and processed milk, which is a consequence of the growth and metabolic activities of psychrotrophic bacteria, able to grow under 7oC or lower temperatures. Although most of these microorganisms are destroyed by heat treatment, some have the potential to produce termoresistant proteolytic and lipolytic enzymes that can survive even UHT processing and reduce the processed products quality. Recently, the IN 51 determineds that milk should be refrigerated and stored at the farm what increased the importance of this group of microorganisms. In this work, psychrotrophic bacteria were isolated from 20 communitarian bulk tanks and 23 individual bulk tanks from dairy farms located at Zona da Mata region of Minas Gerais State and from southeastern Rio de Janeiro. Selected milk dilutions were plated on standard agar and after incubation for 10 days at 7oC, five colonies were isolated, firstly using nutrient agar and after using McConkey agar for 24 hours at 21oC. The isolates were identified by morphology, Gram stain method, catalase production, fermentative/oxidative metabolism and by API 20E, API 20NE, API Staph, API Coryne or API 50 CH (BioMerieux). In order to ensure reproductibility, API was repeated for 50% of the isolates. Species identification was considered when APILAB indexes reached 75% or higher. 309 strains were isolated, 250 Gram negative and 59 Gram positive. 250 Gram negative isolates were identified as: Acinetobacter spp. (39), Aeromonas spp. (07), A. Hydrophila (16), A. sobria (1), A. caviae (1), Alcaligenes feacalis (1), Burkholderia cepacia (12), Chryseomonas luteola (3), Enterobacter sp. (1), Ewingella americana(6), Hafnia alvei (7), Klebsiella sp. (1), Klebsiella oxytoca (10), Yersinia spp. (2), Methylobacterium mesophilicum (1), Moraxella spp. (4), Pantoea spp. (16), Pasteurella sp. (1), Pseudomonas spp. (10), P. fluorescens (94), P. putida (3), Serratia spp. (3), Sphigomonas paucomobilis (1). Five isolates kept unidentified. Pseudomonas was the predominant bacteria found (43%) and P. fluorescens the predominant species (37.6%), in accordance with previous reports. Qualitative analysis of proteolytic and lipolytic activity was based on halo formation using caseinate agar and tributirina agar during 72 hours at 21oC and during 10 days at 4°C, 10oC and 7°C. Among 250 Gram negative bacteria found, 104 were identified as Pseudomonas spp. and 60,57% of this group showed proteolytic and lipolytic acitivities over all four studied temperatures. 20% of Acinetobacter, Aeromonas, Alcaligenes, Burkholderia, Chryseomonas, Methylobacterium, Moraxella presented only lipolytic activity. Some isolates presented enzymatic activity in one or more studied temperatures. Among Gram positive bacteria, 30.51% were proteolytic and lipolytic at 10oC, 8.47% were proteolytic at 7oC, 10oC, and 21oC, 8.47% were proteolytic at all studied temperatures (4oC, 7oC, 10oC and 21oC) and 3.38% were proteolytic only at 21oC. At 4oC, only one isolate showed proteolytic activity and six isolates were lipolytic. In relation to Gram negative microorganisms, 4% were proteolytic and lipolytic at 7oC, 10oC and 21oC, 10% were proteolytic at 10oC and 4.4% were lipolytic at 4oC, 7oC, 10oC and 21oC, while 6.4% of all isolates were proteolytic and lipolytic at 10oC and 21oC as well as lipolytic at 4oC and 7oC. These findings are in accordance with previous researches that pointed out Pseudomonas as the predominant psycrotrophic flora in stored refrigerated raw milk

Disponibilidade hídrica potencial em face da distribuição espaço-temporal das precipitações no Estado do Rio Grande do Norte

The state of Rio Grande do Norte, possessor of an extremely irregular regime of rains, has the necessity of enlarge and specify the researches about its own hydro-climatic conditions, to achieve trustworthy results that are able to minimize the adversities imposed by these conditions and make possible the implementation of a better planning in the economic activities and of subsistence that somehow utilize of the multiple uses of hydro resources of the State. This way, the daily values observed from the pluviometric series of 166 posts, with 45 years uninterrupted of historic data, were adjusted to the incomplete gamma function to the determination of the probability of rain in the 36 period of ten days in which the year was divided. To the attainment of the α and β parameters of this function it was applied the method of the maximum verisimilitude allowing, in the end, to analyze the temporal and spatial distribution of the rain in the level of 75% of probability. The values of potential evapo-transpiration were calculated by the Linacre method that, through the SURFER software, were confronted with the dependant rain, obtaining, in this way, the spatialization of the potential hydro availability, which the values can be known to any period of ten days of the year, city and/or region of the state of Rio Grande do Norte. With the identification of the main meteorological systems that act in the State, we sought to better comprehend how this systems interfere, in the irregular regime of rain, in the situations of several clime in the major part of Rio Grande do Norte and in the hydro regional balance. And, finally, with these data in hand and with the generated maps, we verified that space-temporal distribution of the rain and of the potential hydro availability were heterogeneous in the whole State, mainly in the West and Central regions, inserted in potiguar s semi-arid, which, after the period of the rains station, suffers with dry season and length drought during the rest of the year

Diagnóstico do usuário no aprimoramento dos serviços de tecnologia da informação: um projeto de intervenção para o Ministério Público do Estado do Rio Grande do Norte

The information tecnology (IT) has, over the years, gaining prominence as a strategic element and competitive edge in organizations, public or private. In the judiciary, with the implementation of actions related to Judiciário Eletrônico, information technology (IT), definitely earns its status as a strategic element and significantly raises the level of dependence of the organs of their services and products. Increasingly, the quality of services provided by IT has direct impact on the quality of services provided by the agency as a whole. The Ministério Público do Estado do Rio Grande do Norte (MPRN) deployments shares of Electronic Government, along with an administrative reform, beyond these issues raised, caused a large increase in institutional demand for products and services provided by the Diretoria de Tecnologia da Informação (DTI), a sector responsible for the provision of IT services. Taking as starting point strategic goal set by MPRN to reach a 85% level of user satisfaction in four years, we seek to propose a method that assists in meeting the goal, respecting the capacity constraints of the IT sector. To achieve the proposed objective, we conducted a work in two distinct and complementary stages. In the first step we conducted a case study in MPRN, in which, through an internal and external diagnosis of DTI, accomplished by an action of internal consulting and one research of the user satisfaction, we seek to identify opportunities of change seeking to raise the quality perceived of the services provided by the DTI , from the viewpoint of their customers. The situational report, drawn from the data collected, fostered changes in DTI, which were then evaluated with the managers. In the second stage, with the results obtained in the initial process, empirical observation, evaluation of side projects of quality improvement in the sector, and validation with the managers, of the initial model, we developed an improved process, gazing beyond the identification of gaps in service a strategy for the selection of best management practices and deployment of these, in a incremental and adaptive way, allowing the application of the process in organs with little staff allocated to the provision of information technology services

Fidelidade à área e padrão de associação em Sotalia guianensis, baseado na técnica de foto-identificação

The behavioral patterns follow to environmental changes, including area fidelity and individuals association patterns. Several techniques are used to record these behavioral patterns and the photo-identification has been suggested as a proper tool because of its various advantages. Based on this technique, this research verified, between August of 2005 and January of 2006, area fidelity and association patterns of Sotalia guianensis, at Distrito de Pipa s bays, Rio Grande do Norte State south coast. Besides, we measured the association patterns by using the Jaccard index or Half-Weight Index (HWI). According the observation, 22 individuals were not resighted, 11 were resighted, and 36 new individuals were recorded. Nowadays, 69 individuals are cataloged. The residency rate indicated heterogeneity on studied area permanence and the association patterns between photo-identified seem to be context-specific. In addiction, the comparison of associations between two different age classes showed some individuals more frequently interacting with immature individuals. We also observed fluidity on association patterns among our individuals. We suggest that S. guianensis population from Pipa shows plasticity

Fungos gasteroides (Basidiomycota, Agaricomycetes) de três áreas de semiárido no Estado do Ceará, Brasil

Gasteroid fungi include several distinct lineages of basidiomycetes that were grouped by presenting some striking features in common like angiocarpic development and passive release of basidiospores. For a long period these fungi were accomodate in Gasteromycetes class. However, biochemistry and molecular studies showed the polyphyly of this group and curriently this class lies devoid of taxonomic value. These organisms influence the ecology of the various biomes, however, are poorly studied and knowledge of their diversity in neotropical ecosystems remains insufficient, despite studies that have been developed in recent years. The Brazilian semiarid region has many areas with an unexplored mycobiota. Ceará State has many areas of extreme biological importance and for this study three protected areas were chosen: Área de Proteção Ambiental da Serra da Ibiapaba, Parque Nacional de Ubajara and Área de Proteção Ambiental de Baturité. Therefore, the aim of this study was to inventory gasteroid fungi ocorring in these three areas in the semiarid region of Ceará. The expeditions, herborization and analysis of specimes were based in traditional methodology used to identify gasteroid fungi. Were identified 16 species belong to 5 families: Agaricaceae, Clathraceae, Geastraceae, Nidulariceae and Phallaceae. Morganella nuda Alfredo & Baseia is recorded for the second time in the world, Blumenavia angolensis (Welw. & Curr) Dring and Mutinus elegans (Mont.) E. Fisch. corresponds to a first record in the Brazilian Northeastern. Except for Abrachium floriforme (Baseia & Calonge) Baseia & T.S. Cabral and Geastrum lloydianum Rick, all remaining species are new records for Ceará, increasing the list of gasteroid fungi in the region of 3 for 17 species. Identified species were deposited in the collection of the Herbarium of Universidade Federal do Rio Grande do Norte. Although these areas have proved conducive to the study of gasteroid fungi, more efforts are still needed to increase knowledge of these fungi in the region

Desenvolvimento territorial no Rio Grande do Norte: uma identificação de clusters rurais

The general objective of this study is the identification of rural spaces in Rio Grande do Norte through a territorial approach. It looks if there is spatial correlations between municipalities that influence and are influenced by the rural environment, allowing the identification of clusters. To accomplish this objective it`s used, in the methodology, the factor analysis of principal components to achieve the indicators of rurality and territorial development, that deal with four dimensions of analysis: environmental, political-institutional, economical and spatial. Moreover, to identify the spatial correlations structure between municipalities it used the Moran index to both rurality and territorial development, leading to clustering identification. The results show that the rurality is present in most of Rio Grande do Norte municipalities, except in cases like Mossoró, Pau dos Ferros, Caicó and Natal, where can be regional dynamic poles. It is also verified that the more rural municipalities tend to be less developed, according to the territorial development index, and have less correlations with neighboring municipalities

Identificação de indivíduos vulneráveis no entorno de um hospital universitário: conectando vulnerabilidade, solidariedade e saúde

No entorno de um hospital universitário do interior do estado de São Paulo há pessoas dormindo, se alimentando ou descansando nos gramados e arredores, permanecendo nestes locais durante horas. Este estudo objetivou identificar e caracterizar indivíduos vulneráveis em área externa deste hospital, oferecendo ajuda. A coleta dos dados foi realizada no período de novembro de 2007 a outubro de 2008, semanalmente, em dias e horários sorteados. Identificaram-se pessoas que permaneciam nesses locais, sendo entrevistados 52 sujeitos. Esses indivíduos são, predominantemente, do sexo feminino (67,3%), brancos (51,9%), casados (59,6%), com escolaridade de até quatro anos de estudo (44,2%) e sem profissão definida (84,6%). A maioria aguardava o horário do ônibus da prefeitura de seu município de origem; o tempo médio de espera foi de aproximadamente 90 minutos e grande parte dos sujeitos apresentou necessidades durante os períodos de espera. Foi oferecida ajuda a 15 pessoas que referiram necessidades no momento da entrevista. Concluiu-se que esses indivíduos se encontram em situação de vulnerabilidade individual, social e programática, destacando-se a vulnerabilidade sócio-econômica, apresentam capacidade de autodeterminação reduzida, submetendo-se a condições desfavoráveis por dependerem dos serviços públicos.

Condição ocular dos indivíduos facectomizados na região centro-oeste do estado de São Paulo: estudo populacional

OBJETIVO: Avaliar as causas de baixa visão e cegueira em indivíduos facectomizados, de amostra da população de cidades da região centrooeste do estado de São Paulo. Métodos: Estudo transversal, observacional, feito em cinco cidades da região centro-oeste do estado de São Paulo, em amostra domiciliar e baseada nos dados do último Censo Demográfico (IBGE, 1995), com escolha sistemática dos domicílios. Foi considerada para o presente estudo uma subamostra de indivíduos facectomizados, dos quais foram obtidos dados de identificação e exame oftalmológico completo. Os dados foram avaliados por estatísticas descritivas, análise de freqüência de ocorrência e proporção de concordância, com intervalo de confiança de 95%. RESULTADOS: Dos indivíduos amostrados, 2,37% haviam sido submetidos à facectomia. Dos 201 olhos operados, 26,9% apresentavam acuidade visual compatível com cegueira ou deficiência visual. Com a melhor correção óptica, a acuidade visual permaneceu <0,3 em 19,0%. O exame refracional proporcionou melhora da acuidade visual para 27,9% dos indivíduos facectomizados. As causas de baixa visão foram os erros refrativos não corrigidos, opacidade de cápsula posterior (19,4%), ceratopatia bolhosa (8,3%) coriorretinite cicatricial (8,3%), afacia (8,3%), degeneração macular relacionada a idade (5,5%), leucoma (5,5%), glaucoma (5,5%), atrofia de papila (5,5,%), descolamento de retina (2,8%), atrofia de epitelio pigmentado da retina (2,8%) e alta miopia (2,8%). CONCLUSÃO: Apesar da catarata ser causa de cegueira que pode ser evitável, mesmo após a correção cirúrgica porcentagem expressiva de indivíduos permanece com baixa visão, em geral, em decorrência de fatores relacionados ao seguimento pós-operatório negligenciado.
