Abstract: The objective of this study was to evaluate the physicochemical and microbiological parameters of milk in different lactation phases during a year in two Dairy farms producing type A milk (Brazilian Standards) and classified as Farm 1 (G1) and Farm 2 (G2). The 320 raw milk samples were collected to analyze acidity Dornic, California Mastit Test (CMT), Somatic Cells Counting (SCC) and Cryoscopy (0H) during four seasons, in the period of January 00 to January 005. To data statistical analyses a General linear model (GLM) was used. The CMT, the SCC, acidity Dornic and Cryoscopy (0H) results were not significant (P>0.05), during the year seasons, between the farms and in the different lactation phases. The SCC (9 5.000 cells/mL) average results are in disagreement with the legislation. To the Dornic acidity and Cryoscopy (0H), the values had not exceeded the limit demanded by IN5 . The results of mesophilic aerobic organisms counting during autumn (G ) and during spring (G ) had revealed a disagreement with IN5 . High levels of coliforms (TC) and Escherichia coli (EC) were observed in G in all seasons when compared with G . It was demonstrated that the physical-chemistry and microbiological quality are important to handling practical during milks. O objetivo deste estudo foi avaliar os parametros físico-químicos e microbiológicos do leite em diferentes fases de lacta o, durante as esta es do ano em duas granjas leiteiras produtoras de leite tipo A (Granja (G ) e Granja (G )), no período de janeiro de 00 a janeiro de 005. Foram colhidas e analisadas 0 amostras de leite cru para análise da acidez Dornic, California Mastitis Test (CMT), Contagem de Células Somáticas (CCS) e crioscopia. Para as análises estatísticas dos dados, foram empregados os Modelos Lineares Generalizados (GLM). Constatou-se que os resultados das análises estatísticas n o foram significativos (P>0,05), durante as esta es do ano, nas diferentes fases de lacta o, entre as granjas avaliadas. Os resultados médios para CCS (9 5.000 CCS/mL), est o em desacordo com a legisla o vigente. Com rela o à acidez Dornic e Crioscopia, os valores n o excederam o limite exigido pela IN51. Os resultados das contagens médias de aeróbios mesófilos no outono na G2 e na primavera na G mostraram-se em desacordo com a IN5 . No caso dos Coliformes totais e Escherichia coli , observou-se que os resultados médios foram maiores na G , em todas as esta es do ano. Evidenciou-se que as qualidades físico-químicas e microbiológicas est o principalmente ligadas às práticas de manejo durante a ordenha.

Abstract: In Pernambuco, as well as in the major part of Brazil, milk, especially in small dairy farms, is obtained in poor hygienic conditions, little technology and deficient sanitary control of animals. Raw milk presents low microbiologic quality, which compromises the product’s composition, reduces its shelf life and can constitute risk to public health. Food quality and safety are related to the Good Manufacturing Pratices (GMP). Implementation of GMP results in reduction of the number of microorganisms in milk, leading to a better microbiologic quality and enhanced shelf life of the final product. The aim of this work was to evaluate the impact of implementation of Good Milking Practices on the improvement of microbiological quality of milk, aiming to achieve the standards established by Normative Instruction 51. Different practices of milking were applied in the main points of contamination, identified previously, in four dairy farms of Agreste of Pernambuco. The practices were evaluated through enumeration of indicator microorganisms mesophilic aerobes, psychrotrophics, coagulase positive staphylococci, total coliforms and Escherichia coli before and after the application of the practices. The practices adopted were: elimination of first three jets of milk, immersion of teats in chlorinated solution, vigorous cleaning and posterior inversion of buckets and cans for elimination of residual water. Results showed, with the application of the practices, means reduction of 99.9% for mesophilic aerobes microorganisms. The practices indicated are simple, efficient, of easy adoption in milking routine in any situation of technology at the dairy farms and do not require spends with installations. Em Pernambuco, assim como na maior parte do país, o leite, sobretudo nas pequenas propriedades, é obtido em precárias condi es higiênicas, com pouca tecnologia e deficiente controle sanitário dos animais. O leite cru apresenta baixa qualidade microbiológica, o que compromete a composi o do produto, reduz sua vida de prateleira e pode constituir risco à saúde pública. A qualidade e a seguran a dos alimentos est o associadas às boas práticas de produ o (BPP). A implanta o das BPP resulta na redu o do número de microrganismos do leite levando a uma melhor qualidade microbiológica e maior vida de prateleira do produto final. O objetivo deste trabalho foi avaliar o impacto da implanta o de boas práticas de ordenha na melhoria da qualidade microbiológica do leite, visando atingir os padr es estabelecidos pela Instru o Normativa 51. Foram aplicadas diferentes práticas de

Abstract: Currently, canine obesity is a worldwide problem and is based on the excessive deposit of fat tissue, which plays an important role as a store of energy and endocrine organ. This study aimed to compare the values of systolic blood pressure, serum chemistry profile and glucose metabolism in eight obese dogs without endocrine diseases before and after 16 weeks of a weight loss program. A statistical difference was noticed in the serum levels of alkaline phosphatase, gamma glutamyl transferase, glucose, cholesterol and insulin, before and after the program. Besides, there was a statistical difference between the moments in systolic blood pressure, body weight and body condition scale. Therefore, it was concluded that the use of a diet rich in fiber and protein is suitable for performing weight loss and obese dogs undergoing a weight loss program presented a significant reduction in blood pressure, blood glucose, insulin, blood cholesterol, serum activity of alkaline phosphatase and gamma glutamyl transferase.

Abstract: The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and S o Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus) and scaly-headed parrots (Pionus maximiliani). Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira). Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus). It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments. O objetivo deste trabalho foi pesquisar a frequência de ocorrência e a variedade de parasitas intestinais de animais silvestres de vida livre. Amostras de fezes de mamíferos e aves silvestres de centros de reabilita o dos Estados do Mato Grosso do Sul e S o Paulo, foram analisadas pelos métodos de sedimenta o e de centrífugo-flutua o. Foram encontrados ovos, oocistos, cistos e/ou trofozoítos de parasitas em 71% das amostras. Oocistos de Cryptosporidium sp. foram detectados em amostras de fezes de gato-do-mato-pequeno (Leopardus tigrinus) e maritacas (Pionus maximiliani). Cistos de Giardia foram identificados nas fezes de um veado catingueiro (Mazama gouazoubira). Entre os parasitas mais comuns, foram encontrados ovos de Toxocara cati, Toxascaris leonina e Ancylostoma tubaeforme, além de ovos de Cestoda. Vários ovos de Enterobius sp. foram encontrados nas fezes de bugio (Alouatta seniculus). Neste trabalho concluiu-se que, apesar de pequeno o número de amostras, a diversidade de parasitas encontrados foi relevante. Informa es adicionais sobre a endofauna parasitária em animais silvestres s o necessárias, pois podem sugerir a intera o e proximidade com animais domésticos e/ou o homem. Além disso, maiores est

Abstract: Each year, several outbreaks of foodborne diseases are reported in Parana state, Brazil. Bacteria are responsible for 70% of these outbreaks and 95% of cases of food poisoning. There are reports that kitchen equipment and utensils contaminated have participated of approximately 16% of outbreaks. The aim of this study was to evaluate the microbiological quality of water, fresh foods, frozen foods, ready to eat food and sanitary conditions of three restaurants in Ilha do Mel – Paraná, Brazil, using PetrifilmTM. The results showed that 72.2% surfaces of had unsatisfactory sanitary conditions. Cutting boards, scrub sponge, kitchen sinks and dish towels had the highest average contamination. According to Brazilian law, samples of food outside of the standard were: seafood sauce, with 7,0 x 102 CFU/g of E. Coli, frozen mussels, with 7,0 x 102 CFU/g of E. coli; sample lettuce and grated carrot, considered clean, with 1,0 x 103 e 2,0 x 105 CFU/g of EC, respectively. All samples of food, in general, had high bacterial counts. Vegetables were the main responsible for the contamination of kitchen boards and sinks. The water used in the three restaurants had satisfactory microbiological quality. Better hygienic sanitary conditions were found in the restaurant where the employees had training in good manufacturing practices. Vários surtos de Doen as Transmitidas por Alimentos s o notificadas por ano no estado do Paraná, sendo as bactérias responsáveis por 70% destes surtos e 95% dos casos de toxinfec es alimentares. Existem relatos de que utensílios e equipamentos contaminados participam de, aproximadamente, 16% dos surtos. O objetivo deste trabalho foi avaliar a qualidade microbiológica da água, dos alimentos in natura, congelados e expostos ao consumo e as condi es higiênico-sanitárias de três restaurantes da Ilha do Mel/PR. Para produtos de origem animal, foi determinada a contagem de aeróbios mesófilos, coliformes totais, E. coli e S. aureus. Para equipamentos e utensílios inclui-se, ainda, a contagem de bolores e leveduras. Das superfícies analisadas, 72,2% apresentaram condi es higiênico-sanitárias insatisfatórias. Tábuas plásticas de corte, buchas de lou a, pias e os panos de prato e de pia apresentaram as maiores médias de contamina o. De acordo com a legisla o brasileira, os alimentos encontrados em desacordo com os padr es estabelecidos foram: o mexilh o congelado, com contagens de E. coli de 7,0 x 102 UFC/g; o molho de camar o, com 1,4 x 104 UFC/g; as amostras de alface e cenoura ralada, consideradas limpas, com 1,0 x 103 e 2,0 x 105 UFC/g de EC, res

Abstract: Blood pressure is currently a very important tool for clinical and veterinary surgery, especially in monitoring patients under anesthesia and in emergency situations. Hypertension can cause a number of changes in the body of dogs and cats, especially those who are middle-aged and elderly. In veterinary medicine, the blood pressure can be measured non-invasively and invasively. The non-invasive, or indirect technique, is frequently used during routine examinations since it presents convenience as it can be carried out quickly, although it is less accurate. For this research 245 dogs were selected, with one to ten years of age, of both sexes, castrated and uncastrated of different breeds and body scores. The dogs were weighed and had the body condition score determined using the system of 9 points, being categorized into: Control group, overweight group or obese group. Systolic blood pressure was obtained by non-invasive method using the Doppler flowmeter and the oscillometric method. 48 animals were excluded due to the high variability of values, with systolic blood pressure greater than 160 mm?Hg, as well as uncooperative and/or aggressive patients. There was agreement between both methods in 197 dogs conscious and asymptomatic and, therefore, this study showed that oscillometric method can be used in normotensive patients as the study was conducted in patients of different sizes, breeds, ages, body scores and sexual status.

Abstract: context: a postgraduate and resident trainee mental health assistance center was created in september 1996 within our university. objective: to describe the clinical and demographic profile of its users. type of study: retrospective. setting: universidade federal de s?o paulo - escola paulista de medicina (unifesp-epm). methods: the study was carried between september 1996 and november 2002, when 233 semi-structured registration forms were filled out either by the psychologist or the psychiatrist during their first contact with the trainees, who were medical and nursing residents, and postgraduate students at specialization, master or doctoral levels. the registration forms included demographic, occupational and clinical data. results: the trainees were predominantly young (mean of 27 years old), single (82.0% of cases), women (79.4%), seeking help especially during the first year of training (63.1%). in 70.8% of the cases, they came to the service spontaneously. such individuals showed greater adherence to the treatment than those who were referred by supervisors (p < 0.05). in 30% of the cases, the trainee sought psychological guidance or support at the service due to specific situational conflicts. depression and anxiety disorders were the most frequent diagnoses; 22.3% of the trainees followed up mentioned a tendency towards suicidal thoughts. in comparison with other trainees, there was a higher prevalence of males among the medical residents (p < 0.01), with more cases of sleep disorders (p < 0.05), a smaller number of individuals refraining from the use of alcohol (p < 0.05) and a higher number of trainees requiring leave of absence (p < 0.001). discussion: the first year of training in health sciences is the most stressful, especially for women. depression and anxiety symptoms are common, reflecting transitory self-limited deadaptation. however, the severity of the cases can also be evaluated in view of the large number of trainees who mentioned suicidal ten
Recent reforms in French and German family policies: Similar challenges, different responses
Fagnani,Jeanne; Math,Antoine;
Sociologia, Problemas e Práticas , 2010,
Abstract: this article investigates whether the recent reforms introduced in the family policies of both france and germany are leading the two countries towards some measure of convergence. germany has favoured dramatic changes, especially a new parental leave allowance, while france, for its part, has chosen a more gradual approach that has translated into an enhancement of its promotion of work-family reconciliation policies along with steady increases in spending related to childcare provision over the last decade. despite a rise in its overall supply of childcare germany still lags far behind france in this domain, a phenomenon that can be partially explained by a combination of institutional obstacles, the persistence of social norms governing childcare for under-3s, and excessive demand. we argue that the main drivers for paradigmatic change in germany have been concerns over the consequences of declining fertility; a shortfall of qualified workers; and, the shattering of certitudes following an oecd study on childhood education. in france reforms in parental leave policies have been more incremental with, for example, mothers being encouraged to retain their links to the workforce even while on leave. but while the reforms adopted by germany represent a radical departure from the former ‘male-breadwinner model’, mothers’ employment rates remain lower than in france and german mothers work part-time with much greater frequency than their french counterparts.
The asymptotical error of broadcast gossip averaging algorithms
Paolo Frasca,Fabio Fagnani
Mathematics , 2010,
Abstract: In problems of estimation and control which involve a network, efficient distributed computation of averages is a key issue. This paper presents theoretical and simulation results about the accumulation of errors during the computation of averages by means of iterative "broadcast gossip" algorithms. Using martingale theory, we prove that the expectation of the accumulated error can be bounded from above by a quantity which only depends on the mixing parameter of the algorithm and on few properties of the network: its size, its maximum degree and its spectral gap. Both analytical results and computer simulations show that in several network topologies of applicative interest the accumulated error goes to zero as the size of the network grows large.
