ABSTRACT This research aims at describing data for an epidemiological profile, as well as to contribute to the improvement of systems of information, prevention and risk control of accidents in the workplace in processing and further processing broiler plants. In this study, data from documents of 1,274 investigations of typical work accidents were analyzed. Descriptive statistics were used for the analysis, and the frequency and severity of accidents were calculated according to NBR 14280:2001. The results show that men tend to have more accidents than women; 69.8% of those injured had been in the company for less than 3 years; 37% of the accidents were cuts; 35.6% were bruises; the most affected body parts were hands and fingers, representing a total of 48% of all accidents; 41.6% of victims were not using personal protective equipment (PPE) at the time of the accident; the underlying causative condition of 54.9% of the accidents was the lack of personal safety. The proportion for each accident with leave was 1.7 accidents without leave but with a need for relocation of activity and 10.9 accidents without leave without relocation. There were amputation cases among some of those given leave of absence. For every million hours worked, there were 3.2 accidents with leave and 139.4 days of absence were registered. The study concludes that accident rates in in processing and further processing broiler plants are high, and that it is extremely important to establish an epidemiological profile in order to guide prevention and control actions.

Abstract: ROTSE1 J164341.65+251748.1 was photometrically observed in the V band during three epochs with the 0.84-m telescope of the San Pedro Mártir Observatory in Mexico. Based on additional BVR photometry, we found that the primary star has a spectral type around G0V. The light curve of the system is typical of a W UMa type binary stars and has an orbital period of ≈ 0.323 days. In an effort to gain a better understanding of the binary system and determine its physical properties, we analyzed the light curve with the Wilson and Devinney method. We found that ROTSE1 J164341.65+251748.1 has a mass ratio of ≈ 0.34 and that the less massive component is about 230 K hotter than the primary star. The inclination of the system is ≈ 84.6 degrees, and the degree of over-contact is 11%. The analysis shows the presence of variable bright spots on the primary star.

Resumen: ROTSE1 J164341.65+251748.1 fue observada fotométricamente en la banda V durante tres épocas con el telescopio de 0.84-m del Observatorio de San Pedro Mártir en México. Con base en fotometría BVR adicional, encontramos que la estrella primaria tiene un tipo espectral cercano a G0V. La curva del luz del sistema es característica de los sistemas binarios del tipo W UMa y tiene un periodo orbital de ≈ 0.323 días. Con el propósito de entender mejor a este sistema binario, hemos analizado su curva de luz con ayuda del método de Wilson y Devinney. Hemos encontrado que ROTSE1 J164341.65+251748.1 tiene una razón de masas de ≈ 0.34 y que la componente menos masiva es ≈ 230 K más caliente que la estrella primaria. La inclinación del sistema es ≈ 84.6 grados y el sobre-contacto es de 11%. El análisis también mostró la presencia de manchas brillantes variables sobre la estrella primaria.

A piometra é uma infecção aguda ou crônica do útero que ocorre frequentemente em cadelas não castradas, podendo também ocorrer em gatas domésticas e selvagens, sendo poucos os estudos relacionados à piometra em grandes felídeos. O objetivo deste relato foi descrever um caso de piometra em uma leoa (Panthera leo) de cativeiro, as lesões de necropsia e histológicas, bem como os resultados da análise microbiológica. Uma leoa com aproximadamente 23 anos, pertencente a um criadouro conservacionista de Santa Maria-RS, foi encontrada morta pela manhã em seu recinto. Após coleta de dados, procedeu-se à necropsia e à coleta de material para análise histopatológica e bacteriológica. A análise microbiológica revelou predomínio das bactérias Streptococcus sp. e Escherichia coli no conteúdo purulento do útero, caracterizando como piometra, e a bactéria predominante em plasma, fígado e medula óssea foi E. coli. De acordo com o laudo histopatológico, as alterações observadas nessa leoa sugerem um quadro de septicemia grave, sendo a origem do foco infeccioso bacteriano, provavelmente, a piometra. Considera-se importante chamar a atenção dos médicos veterinários de animais selvagens para um diagnóstico precoce dessa doença, que é comum em cadelas, mas que pode acometer também felídeos selvagens e levá-los à morte.

Pyometra is an acute or chronic uterus infection that occurs often in not spayed dogs, but may also occur in wild and domestic cats, and there are few studies related to pyometra in big cats. The aim of this report was to describe a case of pyometra in a lion (Panthera leo) in captivity, the gross and microscopic lesions found at necropsy, and the results of the microbiological analysis. A female with approximately 23 years of age, belonging to a Conservationist Breeding Center located in Santa Maria-RS-Brazil was found dead in her enclosure in the morning. After data collection, we proceeded to the autopsy and collection of material for histopathological and bacteriological analyzes. Microbiological analysis revealed a predominance of the bacteria Streptococcus sp and Escherichia coli in the uterus content, characterized as pyometra and the predominant bacterium in the plasma, liver and bone marrow was Escherichia coli. According to histopathology, the changes observed in this lioness suggest a framework of severe septicemia, being the source of the bacterial infection, probably, pyometra. It is considered important to draw the attention of zoo and wildlife veterinarians for an early diagnosis of this common disease in dogs, which can also affect large wild cats and lead them to death.

From uvby -β photometry of the open clusters NGC 6811 (75 stars), and NGC 6830 (19 stars) we were able to determine membership of the stars to each cluster, and fix the age and reddening for each. Since several short period stars have recently been found, we have carried out a study of these variables.

A partir de la fotometría fotoeléctrica uvby - β de los cúmulos abiertos NGC 6811 (75 estrellas) y NGC 6830 (19 estrellas) realizamos la determinación de distancias y, por ende, la pertenencia de las estrellas a cada cúmulo. Asimismo, se determinaron la edad y el enrojecimiento de cada uno. Dado que recientemente se han determinado estrellas variables para el primero, realizamos un estudio de dichas variables.

This work presents some experiences in producing building materials, such as clay bricks, from an alternative energy source that replaces wood or firewood by waste lignocellulosic material submited to the process of densification under low pressure. The densification process at low pressure involves the use of a binder; this paper proposes the use of clay material as binder. The main objective of this study was to evaluate the effect in the consumption of biofuel during the production of handmade bricks, partially replacing wood by densified biomass. Some properties of the biofuel are identified to increase the bricks-to-fuel consumption ratio from 1.1 to 1.4. This improves the efficiency of the production process, reduces specific consumption regarding the use of traditional fuels with its consequent environmental improvement of the process.

En el presente trabajo se exponen algunas experiencias en el propósito de obtener materiales de construcción como los ladrillos rojos cocidos a partir de una fuente energética alternativa proveniente de sustituir la madera o leña por residuos de material lignocelulósico sometidos al proceso de densificación con baja presión. El proceso de densificación con baja presión implica el empleo de algún tipo de aglomerante para lo cual en este trabajo se propone el uso del material arcilloso. Sobre esta base el objetivo principal de este estudio es evaluar el efecto que se produce en el consumo específico del biocombustible durante la fabricación artesanal de ladrillos al sustituir parcialmente la leña por la biomasa densificada. Se expone la relación entre algunas propiedades del biocombustible que permiten aumentar la relación ladrillos / kilogramo de combustible desde 1.1 a 1.4 lo que mejora la eficiencia del proceso de fabricación de ladrillos disminuyendo el consumo especifico con respecto al uso del combustible tradicional con la consiguiente mejora ambiental del proceso.

CONTEXTUALIZAÇÃO: As doenças pulmonares obstrutivas podem interferir negativamente na qualidade de vida (QV) dos pacientes, sendo que questionários específicos, como o Chronic Respiratory Questionnaire (CRQ), são aplicados para quantificar o impacto da doença e para mensurar os efeitos de diferentes protocolos de reabilitação. OBJETIVOS: Avaliar a eficácia da reabilitação pulmonar uma vez por semana associada a exercícios domiciliares em pacientes com doença pulmonar obstrutiva por meio das comparações do CRQ, das pressões respiratórias máximas (PImáx e PEmáx) e da distância percorrida no teste de caminhada de seis minutos (TC6) pré e pós-tratamento. MÉTODO: O estudo foi desenvolvido no Ambulatório de Fisioterapia do hospital. Foram avaliados 34 portadores de doença pulmonar obstrutiva de ambos os sexos, sendo incluídos, no estudo, 19 pacientes, com idade média de 60,8 ± 14,2 anos. Todos realizaram avaliação e reavaliação fisioterapêutica contendo medidas de PImáx, PEmáx, TC6, e questionário CRQ. A fisioterapia era composta de exercícios respiratórios, aeróbios e resistidos, com freqüência de uma vez por semana, durante 12 semanas, associados a exercícios domiciliares duas vezes na semana. RESULTADOS: Foram utilizados os testes de Wilcoxon e de correlação de Spearman. Verificou-se diferença estatisticamente significativa nos períodos pré e pós-reabilitação para todos os domínios do CRQ (p< 0,05), na PImáx (p= 0,01) e PEmáx (p= 0,002). CONCLUSÃO: O programa proposto melhorou a qualidade de vida e promoveu incrementos nas pressões respiratórias máximas de pneumopatas obstrutivos, apesar de a literatura atual sugerir maior freqüência de treinamento.

BACKGROUND: Obstructive pulmonary diseases may interfere negatively with patients' quality of life (QOL). Specific QOL questionnaires such as the Chronic Respiratory Questionnaire (CRQ) have been used to quantify the impact of the disease and measure the effects of different rehabilitation protocols. OBJECTIVE: To evaluate the effectiveness of pulmonary rehabilitation performed once a week in association with exercises at home among patients with obstructive pulmonary disease, by means of CRQ comparisons, maximum respiratory pressures (MIP and MEP) and six-minute walking distance test (6MWD), before and after treatment. METHODS: This study was developed in the physical therapy outpatient clinic of the hospital. Thirty-four patients of both sexes with obstructive pulmonary disease were evaluated, and nineteen (mean age: 60.8 ± 14.2 years) were included in the study. These subjects all underwent physiotherapeutic evaluation and reevaluation with the CRQ and measurements of MIP, MEP and 6MWD. The physical therapy consisted of respiratory, aerobic and resistance exercises once a week for 12 weeks, together with home exercises twice a week. RESULTS: The Wilcoxon test and Spearman correlation were used. Statistically significant differences between evaluations before and after rehabilitation were found for all CRQ domains (p< 0.05), MIP (p= 0.01) and MEP (p= 0.002). CONCLUSION: The proposed program improved QOL and promoted increases in maximum respiratory pressures among these patients with obstructive pulmonary disease, even though the current literature suggests that higher frequency of training is needed.

From uvby photometry of 75 stars in the direction of NGC 7063 we were able to determine membership of some stars and fix the distance (722 ±105 pc), log age (8.146) and reddening (E(b - y) = 0.091 ± 0.039 mag) for the cluster.

Mediante fotometría de 75 estrellas en la dirección de NGC 7063 se ha determinado la membresía de algunas estrellas, establecido su distancia (722 ± 105 pc), su edad (log edad de 8.146) y su enrojecimiento (E(b - y) = 0.091 ± 0.039 mag).

O processo de especiação ocorre pela evolução de qualquer uma das diversas formas de isolamento reprodutivo entre táxons, incluindo inviabilidade de híbridos. Neste trabalho, linhagens provenientes de populações alopátricas de espécies de Drosophila do cluster buzzatii foram cruzadas experimentalmente com o objetivo de avaliar suas relações reprodutivas e citogenéticas, e contribuir para o entendimento do isolamento reprodutivo neste grupo de espécies intimamente relacionadas. Os cruzamentos dentro de uma mesma linhagem foram altamente férteis, contudo as diferenças na fertilidade e fecundidade encontradas intra e interespecificamente são discutidas neste artigo. Dos 30 cruzamentos interespecíficos, 63% foram parcialmente ou completamente estéreis. Cinqüenta e três por cento dos cruzamentos de F1 interespecíficos (fêmeas e machos F1 cruzados entre si) também foram parcialmente ou completamente estéreis, em contraste com apenas um, em 24 cruzamentos de F1 intra-específicos, que foi parcialmente estéril. A análise dos cromossomos politênicos nos híbridos revelou sinapse completa, exceto nos microcromossomos (VI) e na região proximal do cromossomo X. A divergência intra-específica e o grau variável de pareamento cromossômico, observados neste estudo, revelam parte da complexidade do processo de especiação pertinente ao cluster buzzatii, o que é consistente com diferentes caracteres estudados neste cluster.

The process of speciation occurs through the evolution of any of several forms of reproductive isolation between taxa, including inviability of hybrids. In this work, strains derived from allopatric populations of Drosophila buzzatii cluster species were experimentally crossed in order to evaluate their reproductive and cytogenetic relationships, and to contribute toward understanding the reproductive isolation in this group of sibling species. Although intrastrain crosses were highly fertile, we consider it relevant to discuss the differences in intra- and interspecific fertility and fecundity here. Among 30 interspecific crosses, about 63% were partially or completely sterile. Fifty three percent of interspecific F1 crosses (female and male F1 crossed) were also partially or completely sterile, in contrast to only one out of 24 intraspecific F1 crosses that was partially sterile. An analysis of hybrid polytene chromosomes revealed complete synapsis, except in the microchromosomes (VI) and in the proximal region of the X chromosome. The intraspecific divergence observed in this study and the variable degree of chromosome pairing shown here reveal part of the complexity of the speciation process pertinent to Drosophila buzzatii cluster, which is consistent with different traits studied in this cluster.

It is presented a theoretical study on electron -CO collisions in the (5-20) eV energy range. Specifically, elastic differential cross sections (DCS) are calculated using the configuration interaction (CI) method to describe the target. Static and exchange contributions to the interaction potential are obtained exactly from a CI wave function with single and double excitations. The DCS are obtained using the Schwinger variational iterative method (SVIM). It is observed that the discrepancies between Hartree-Fock and CI results are more significant for low energies and small angles.

No grupo repleta de Drosophila, o estabelecimento de subgrupos e complexos realizado com base em evidências citológicas e morfológicas é suportado por testes de isolamento reprodutivo. Entre as espécies do grupo repleta, o cluster buzzatii, devido a seu politipismo e polimorfismo, é um excelente material para estudos ecológicos e de especiação. Alguns cruzamentos interespecíficos envolvendo linhagens de Drosophila seriema, Drosophila sp. B, D. koepferae e D. buzzatii foram completamente estéreis, enquanto outros produziram híbridos F1 que não deixaram F2. No presente trabalho são apresentados dados sobre a duração da corte e ocorrência de cópula dos intercruzamentos estéreis e dados sobre a mobilidade dos espermatozóides dos híbridos F1 que não deixaram F2. Não houve ocorrência de cópula no período de 1 hora de observação e os espermatozóides dos híbridos analisados não foram móveis em qualquer das idades testadas (3, 7, 9 e 10 dias de idade). Houve alta variação na duração média da corte e na porcentagem dos machos que cortejaram as fêmeas. A ausência de cópula e esterilidade dos machos F1 indica mecanismos pré e pós-zigótico operando entre as espécies desse cluster. Os dados também mostram diferentes níveis de compatibilidade reprodutiva entre linhagens classificadas como da mesma espécie mas de diferentes localidades geográficas.

In the Drosophila repleta group the establishment of subgroups and complexes made on the basis of morphological and cytological evidences is supported by tests of reproductive isolation. Among species in the repleta group, the buzzatii cluster, due to its polymorphism and polytipism, is an excellent material for ecological and speciation studies. Some interspecific crosses involving Drosophila seriema, Drosophila sp. B, D. koepferae and D. buzzatii strains were completely sterile while others involving strains from these species produced F1 hybrids that did not yield F2. In the present work, data on courtship duration and copula occurrence obtained in the analysis of flies from parental sterile crosses and on spermatozoon mobility observed in F1 hybrids that did not yield F2 are presented. Copula did not occur during one hour of observation and the spermatozoon also did not show mobility at any of the analyzed stages (3, 7, 9 and 10 days old). There was a high variation in courtship average duration and in the percentage of males that courted the females. The reproductive isolation mechanisms indicated by these observations were pre and post-zygotic, as supported by the absence of copula and male sterility. Data obtained also showed the occurrence of different degrees of reproductive compatibility among the strains classified as the same species but from distinct geographic localities.

In this work we present a theoretical study on electron scattering by both polar and nonpolar polyatomic molecules in the low-energy range. More specifically, we report calculated elastic and rotationally inelastic differential cross sections for electron scattering by CH4, H2O, and H2S in the (2.14-30)-eV range. Exact static-exchange plus model correlation-polarization potentials are used to represent the electron-molecule interaction. The Schwinger variational iterative method is used to solve the scattering equations. In addition, the adiabatic-nuclei-rotation approximation is applied to calculate rotational cross sections. The comparison of our calculated results with experimental and other theoretical data available in the literature is encouraging.

Recently we have extended our codes based on the Schwinger variational iterative method in order to study elastic electron scattering by non-planar molecules with symmetries reducible to the C2v point group and also to include a correlation- polarization contribution to the electron-molecule interaction potential. In this work we report the first application of these newly extended codes to the calculation of cross sections for low-energy elastic scattering of electron by methane. Differential, integral and momentum-transfer cross sections were calculated in the 0.1-50 eV incident energy range. Comparison of our results with the extensive available data, both experimental and theoretical, reveals the reliability of our method. Particularly, the Ramsauer minimum at around 0.4 eV and the resonance structure at around 8 eV are well reproduced in our calculations.

Foi estudado o LCR de 85 pacientes com AIDS e criptococose do SNC. O diagnóstico clínico e imunológico de AIDS foi previamente estabelecido em todos os casos. Os resultados foram comparados aos de grupo de 50 paciestes com neurocriptococose porém sem AIDS (grupo não-AIDS). Neste grupo 22 pacientes eram imunossuprimidos após transplante renal. Nos pacientes do grupo AIDS predominavam no LCR: detecção da levedura no exame direto (câmara de Fuchs-Rosenthal de contagem de células), culturas da levedura positivas e aumento do teor de globulinas gama. No grupo não-AIDS predominavam: pleocitose, presença de polinucleares neutrófilos e aumento da concentração protéica total. As diferenças encontradas entre os dois grupos são discutidas, salientando-se as modificações imunes induzidas no SNC/LCR pelo HIV. Conclui-se que na neurocriptococose em pacientes com AIDS o LCR evidenciou mais a infecção pelo fungo que a resposta inflamatória à infecção. Esta última predominou no LCR de pacientes do grupo neurocriptococose não-AIDS.

In an eight years time period (July 1984-June 1992) CSF samples of 40718 patients were studied, and 610 were from patients with AIDS clinically diagnosed and immunologically confirmed through HIV antibodies detection. Among opportunistic infections detected in them 85 were CNS cryptococcosis. For the purpose of this study the CSF of these 85 patients are the AIDS group of CNS cryptococcosis. For comparison, CSF data from 50 patients with CNS cryptococcosis but without AIDS were taken (non-AIDS group); in this group, 22 patients were immunosuppressed after renal transplant. In AIDS group, the more frequent CSF findings were: yeast presence at direct exam (Fuchs-Rosenthal cell counting chamber), growing of the yeast in cultures, and gamma globulins increase. In non-AIDS group were more frequent: hypereytosis, neutrophil cells presence, and total protein increase. Differences between the two groups are discussed taking into account CNS/CSF immune changes induced by HIV infection. It is concluded that in CNS cryptococcosis of patients with AIDS the CSF evidenced more extensive signs of the fungal opportunistic infection than signs of inflammatory response to the infection. The latter were more prominent among patients of the non-AIDS group of CNS cryptococcosis.
