Abstract: Amostras de leite total (leite do tanque) de 33 rebanhos foram coletadas na plataforma de recep o da indústria laticinista e cultivadas para detectar patógenos específicos (contagiosos) da mastite. Foi feita a contagem de células somáticas (CCS) das amostras utilizando o equipamento Fossomatic 90. Em 13 e 12 rebanhos avaliaram-se duas e três amostras semanais consecutivas, respectivamente, e em oito avaliou-se apenas uma. Foram também examinadas três amostras diárias consecutivas do leite do tanque e amostras dos quartos mamários individuais, coletadas na própria fazenda, de todas as vacas em lacta o de quatro rebanhos (A, B, C e D). As amostras de leite dos quartos mamários individuais foram cultivadas em ágar sangue e as amostras do tanque, em placas de TKT, Sal Manitol, MacConkey e Sabouraud contendo cloranfenicol. Dos 33 rebanhos cujas amostras foram obtidas na plataforma de recep o da indústria, isolou-se Staphylococcus aureus de 26, nove desses em associa o com Streptococcus agalactiae e em três rebanhos isolou-se somente S. agalactiae. Nove rebanhos tiveram CCS acima de 500.000 ml-1 e 21, abaixo de 400.000 ml-1. Em cinco dos nove rebanhos com CCS acima de 500.000 ml-1 foram isolados S. aureus e S. agalactiae, em três, apenas S. aureus e em um, apenas S. agalactiae. Seis rebanhos apresentaram CCS abaixo de 200.000 ml-1; de um deles foram isolados S. aureus e S. agalactiae, de três, S. aureus e os outros dois foram negativos para estes dois patógenos. Os resultados encontrados nos quatro rebanhos cujas amostras foram coletadas na própria fazenda mostraram que S. aureus foi isolado nas seguintes porcentagens dos animais: 1,8%, 19,2%, 17,0% e 8,4% e dos quartos mamários: 0,9%, 5,9%, 5,4% e 2,2%, respectivamente, para os rebanhos A, B, C e D. S. agalactiae foi isolado dos rebanhos A, C e D. Nestes três rebanhos, as porcentagens de isolamento foram, respectivamente, 1,8%, 10,6% e 8,4% para as vacas e 0,46%, 3,8% e 3,7% para os quartos mamários. S. aureus foi isolado de todas três amostras do tanque dos rebanhos A, B e D. Somente a terceira amostra do rebanho C foi positiva para S. aureus. S agalactiae foi recuperado de todas as amostras do rebanho D, duas do rebanho C e de uma do rebanho A. Todas as amostras do tanque dos rebanhos A, B, C e D apresentaram contamina o com coliformes e somente uma das amostras coletadas na plataforma de recep o da indústria foi negativa para coliformes. Leveduras foram isoladas de 16 amostras coletadas na indústria e de todas amostras do tanque dos rebanhos A, B, C e D. N o foram isolados coliformes ou leveduras do

Acta Scientiarum : Education , 2011,
Abstract: Os docentes de pós-gradua o apresentaram aumento nos pedidos de licen as médicas, principalmente por sintomas ou sequelas de doen as cardiovasculares. Com isso, o objetivo deste trabalho foi, por meio de um questionário direcionado a professores de pós-gradua o, quantificar entre eles quantos realizavam atividades físicas frequentes, dietas balanceadas e visitas médicas, e outros fatores, e comparar isso com: i) a ocorrência de interven es cardíacas, doen as coronarianas e acidentes vasculares cerebrais; ii) o número de produ o científica e o número de orientando médio por ano. Foram respondidos e analisados 540 questionários. A hipótese deste trabalho foi aceita, ou seja, quanto maiores o número de produ o científica e o número de orientandos em média por ano, maiores foram as ocorrências médias de interven es cardíacas, doen as coronarianas e os acidentes vasculares cerebrais (hemorrágico e isquêmico) em docentes de pós-gradua o, principalmente, pela falta de dieta equilibrada e balanceada, de atividades físicas supervisionadas regularmente, e visitas médicas frequentes, justificados pela excessiva carga horária fora do expediente, para se manter os indicadores de qualidade dos cursos de pós-gradua o e de seus currículos atualizados. Teachers of post-graduate programs presented an increase in requests for sick leaves, mainly by symptoms or sequela of cardiovascular diseases. By using a questionnaire addressed to teachers of post-graduate courses, this study aimed to: i) identify how many of them had performed frequent physical exercise, balanced diets and medical visits, and other factors, and compare this: i) with the occurrence of cardiac interventions, coronary heart diseases, strokes and cerebral vascular accident; and ii) with the number of scientific production and the average number of advisees per year. 540 questionnaires were returned and analyzed. Our working hypothesis was accepted, that is: the increase in the number of scientific production and the average number of advisees per year was directly related with the increase on the average occurrence of cardiac procedures, coronary heart disease, stroke and cerebral vascular accident (ischemic and hemorrhagic) in teachers of post-graduation, mainly due to the lack of a balanced diet, physical activities regularly supervised, and frequent medical visits, which is justified by the excessive workload out of work time in order to maintain the quality indicators of post-graduate programs and updated curriculum.

Otacílio Antunes Santana,José Iman? Encinas
Biotemas , 2008,
Abstract: This work aimed to i) carry out a survey of exotic tree species, ii) observe their impact on Cerrado native species, and iii) compare the results with control areas. Twenty-two exotic species were sampled in the studied plots near landfills that were shared by thirteen families. Just two species were sampled in the control areas. Landfills enhance the incidence of exotic species. This causes a gradient of distribution in the individuals, a standard which is not observed in the control areas.

Abstract: the advance of the agricultural frontier, characterized by the conversion of natural ecosystems into cultivated areas, was intensified in the last decades. most of the practices used to manage soils cause changes in the soil quality and soil organic matter (som) dynamics. studying the impact of different management systems is essential to choose the most adequate soil management practices. this study aimed to evaluate different som fractions and carbon and nitrogen storage of a very clayey typic dystroferric red latosol (oxisol) under the following use and management systems: native forest (mtn), eucalyptus (euc), pine (pin), pasture (pas), corn under minimum tillage (mcm) and corn under conventional till (mpc). the soil samples were collected in september 2004, in the 0-10, 10-20 and 20-40 cm layers to assess organic carbon (oc) and total nitrogen (tn) storage, in the 0-5 and 0-10 cm layers for the physical-densimetric som fractionation, and at 0-5 cm to measure the carbon content of the microbial biomass (cmic). oc storage in the euc soil was higher than in the mtn soil. the relative contribution of c increased in the order: c-clay > c-silt > c-sand > clf. the largest proportion (> 90 %) of oc was associated to the heavy fraction of som, with values close to 98 % in the tillage systems with corn (mpc and mcm). the cmic and c-light fraction (clf) were more sensitive to evaluate changes in som dynamics caused by the different use and management systems of the studied latosol.

Biotemas , 2005,
Abstract: This note had the objective reports, the species of Spalangia in pupae of dipterous present in several substracts, collected in the South of State of Goiás, Brazil, from May 1998 to June 2004. The dipterous pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of the flies and/or their parasitoids. The overall percentage of parasitism was 1.82%. The percentage of parasitism presented by the parasitoid species Spalangia drosophilae Ashmead, Spalangia endius Walker and Spalangia nigra Latrielle were of 2.63%, 0.92% and 0.14%, respectively.

Abstract: the daily weight gain and economic aspects of beef cattle raised on tropical pastures receiving two types of mineral supplements were evaluated during 112-183 days during the wet season in 4 herds. on each farm the animals were divided into two groups. for one group a commercial mineral mixture was used, and to the other group a selective mineral mixture containing only na, p, cu and co was offered. the cattle were weighed every 30 days, and the mineral supplement intake was measured monthly. the daily weight gain of the animals receiving the selective mineral mixture was greater in three farms. only on the second farm the group receiving the commercial mineral mixture had a superior daily weight gain. the daily intake of the selective mineral mixture was lower in all groups and was attributed to the high amount of nacl in these mixtures. the selective mineral supplementation was 3 up to 7 times more economic than the conventional supplementation with a "complete" mineral mix. throughout the experimental period the animals did not show any direct or indirect clinical signs of mineral deficiency. the results of these experiments confirms the hypothesis that selective mineral supplementation - i.e. supplementation of the mineral element(s) deficient - was correct and results in expressive reduction of the cost with the mineral supplementation for beef cattle.
