Abstract: The aim of this study is to describe a Q fever outbreak that affected the staff of a machine-tool factory in the Basque Country between 2009/12/20 and 2010/02/23. Study subjects were interviewed using a Q fever specific questionnaire and tested for Q fever serology (immunofluorescence assay with phase II antigen) and detecting Coxiella burnetii DNA using real-time PCR. We interviewed and tested 40 employees (90% of the staff). 33 employees, all of them men, had positive serology (attack rate 82.5%, 95% CI: 70.2–94.8). Mean age was 43.7 years (95% CI: 38.7–48.7) in positive men, 33.7 years (95% CI: ?16.6–83.9) in negative men, and 36.25 (95% CI: 27.5–45.0) in women (all negatives). 15 cases (45.5%) were asymptomatic, 9 (27.3%) had flu-like symptoms, and the other 9 (27.3%) had developed radiologically confirmed pneumonia. We obtained 28 blood samples, 22 faeces samples, 11 milk samples, and one vaginal swab from 28 goats resting in a stable near the factory. Serology was positive in 18 goats (64.3%). All environmental samples were negative. 1. Introduction and Background Q fever is a ubiquitous zoonosis caused by Coxiella burnetii, an obligate intracellular coccobacillus, whose incubation period varies from two to six weeks, depending on the infective dose and host. Most cases are asymptomatic (60%) or have mild flu-like symptoms. Only 20% of infected patients seek medical attention, 2 to 3% are admitted to a hospital and the case fatality ratio is 1 to 2% [1, 2]. Symptomatic patients present with a sudden onset of high fever, chills, severe headache, and dyspnoea. In some patients, the clinical course is complicated by pericarditis, myocarditis, pancreatitis, or haemolytic anaemia. A small proportion of infected patients develop chronic Q fever. Endocarditis is the most frequent complication, about 1% of patients, following Q fever. The most important reservoir are sheep, goats, and cattle. Domestic animals such as dogs, cats, rabbits, and birds can also carry the disease. Ticks are thought to spread the disease among animals. Infected animals excrete the bacteria in milk, faeces, urine, and in high concentrations in amniotic fluid and the placenta. The animals are often asymptomatic except for increased incidence of spontaneous abortion. Infection in humans occurs through inhalation of contaminated aerosols or ingestion of unpasteurised milk. C. burnetii is resistant to chemical and physical disinfectants. A small inoculums is sufficient to cause clinical illness. Human-to-human transmission does not usually occur, although it has been described
Características magnéticas y microestructurales de aceros eléctricos con alto silicio producidos por inmersión y recocido de difusión
Ros-Yá?ez, T.,Alonso, C.,Gamarra, M.,Barros, J.
Revista de Metalurgia , 2005,
Abstract: Electrical steels with high silicon content (up to 6.5 wt % Si) are difficult to process by conventional metallurgical routes: ordering phenomena make the material too brittle to be cold rolled. A hot dipping and diffusion annealing process appears to be an alternative production route to obtain steel with a high silicon and aluminium content avoiding rolling problems. Surface alloying with silicon (Si) and aluminium (Al) is achieved on a conventional steel substrate by hot dipping in a hypereutectic Al-Si-bath followed by a diffusion annealing treatment. The diffusion annealing allows the homogenization of the composition obtaining a homogeneous concentration of 6.5 % Si over the thickness depending on the temperature and annealing time necessary for the diffusion of the elements present in the coating. Also, these elements can be distributed in a controlled non-uniform way over the thickness of the sheet. Los aceros eléctricos con alto contenido en silicio (hasta 6,5 % Si) son difíciles de procesar usando procedimientos convencionales: fenómenos de ordenamiento hacen que el material sea muy frágil para ser laminado en frío. El proceso de "inmersión en caliente y recocido de difusión" es una vía alternativa para obtener aceros de alto contenido en silicio (Si) y, eventualmente, también aluminio (Al), evitando los problemas durante la laminación. Los substratos con hasta 3,5 m'% de silicio se sumergen en un ba o hipereutéctico de ALSi para depositar en su superficie una capa rica en silicio. Un recocido posterior permite lograr diferentes perfiles de concentración de este último como, por ejemplo, concentración homogénea de 6,5 % en todo el espesor o perfiles específicos con por ejemplo 6,5 % de Si en la superficie y 3,5 % en el interior de la lámina. En estos materiales se obtuvieron excelentes valores, en cuanto a pérdidas eléctricas.

Abstract: A model that reproduces the coupled deformation and two-phase flow(with special interest to gas migration) through a waste containment engineered barrier system has been developed. The simulation presented in this paper is novel because variable permeability interfaces that depend on deformation are introduced to model the contacts between backfill materials and solid rock or concrete structures. Calculated results of pressures,stresses and volumetric water contents are compared with measurements showing an encouraging agreement which permits to conclude that the model is quite accurate in representing the actual processes that take place in a large-scale in-situ test.
Ciudad, poder, identidad. Bilbao: pasion y muerte de lo urbano.
Garikoitz Gamarra
Bifurcaciones , 2005,
Abstract: En los últimos veinte a os ha surgido lo que se ha dado en llamar la “ciudad postmoderna”, lo que nosotros denominaremos “ciudad del espectáculo”. El capitalismo tardío ha modificado, una vez más, el significado y puesto de la ciudad, pasando del predominio de lo productivo, en tanto que centros industriales y financieros, a la prioridad del ocio y el sector terciario. La ciudad del espectáculo se yergue como mercancía en competición con el resto de ciudades y productos. Ya no es el espacio de interacción entre los ciudadanos, dispuesta para su uso, ni tan siquiera el antiguo refugio; ahora aparece como piedra preciosa surgida por sí misma de las entra as de la naturaleza para ser admirada. Ya no es la ciudad de los ciudadanos sino de los consumidores, de los turistas. La transformación que ha sufrido Bilbao en los últimos diez a os viene a ser un ejemplo palpable de este fenómeno.
Intrahost distribution and trasmission of a new species of cyclopoid copepod endosymbiotic to a freshwater snail, Pomacea canaliculata (Caenogastropoda, Ampullariidae) from Argentina

Abstract: a new species of cyclopoid copepod, ozmana huarpium, is described as a symbiont to pomacea canaliculata (lamarck 1822) (caenogastropoda, ampullariidae). rather large numbers (about one hundred copepods per snail) were found, although there was no evidence of harm to the host. to our knowledge, o. haemophila (symbiont to p. maculata), and the currently described species, o. huarpium, are the only copepod species ever recorded as endosymbionts to freshwater invertebrates. while o. haemophila is restricted to the haemocoel of its host, o. huarpium predominate in the penis sheath, the ctenidium and the mantle cavity, figuring in these pallial organs 63-65 % of total mature forms. the sex ratio of the symbiont is skewed to the female side in these organs, specially in male hosts. the hypothesis that a special female tropism for the male host's pallial organs might ensure interindividual transmission of the symbiont was tested, with indications that the symbiont is mainly transmitted during copulation.

Abstract: the aim of this study was to describe cervical cancer mortality trends in brazil for the period 1981-2006. cervical cancer mortality was corrected on the basis of proportional redistribution of the deaths from "malignant neoplasm of uterus, part unspecified". time trends were evaluated by means of simple linear regression. after correction, cervical cancer ranked second among the leading causes of death from cancer in the female population up to 2005, with a downward trend for the country as a whole, a decline in the state capitals, and a stable trend in the municipalities in the interior. a downward trend was confirmed in the state capitals in all geographic regions of the country. in the municipalities in the interior, there was an increase in the north and northeast regions, a decline in the southeast and south, and a stable trend in the central-west. although uneven, the decline began to take consistent shape in the country. even better results could be achieved by investing in the expansion of screening coverage, especially among the populations at greatest risk.
Tendência da mortalidade por cancer nas capitais e interior do Brasil entre 1980 e 2006

Abstract: objective: to analyze the corrected trend of overall cancer mortality and leading sites in the state capitals and other municipalities of brazil between 1980 and 2006. methods: data on deaths (n = 2,585,012) caused by cancer between 1980 and 2006 were obtained from sistema de informa??es sobre mortalidade (mortality information system), and demographic data were provided by instituto brasileiro de geografia e estatística (brazilian institute of geography and statistics). the rates of overall cancer mortality and major types were corrected by proportionally redistributing 50% of ill-defined causes of death and standardizing them by age according to the standard world population. trend curves for brazil and its major regions were calculated for state capitals and other municipalities according to sex, and were evaluated by means of simple linear regression. results: among men, ascending mortality rates were observed for lung, prostate and colorectal cancer; declining rates for stomach cancer; and stable rates for esophagus cancer. among women, mortality from breast, lung and colorectal cancer increased, and the rates for cervical and stomach cancer declined. mortality evolution varied across the regions of brazil, with distinct patterns between state capitals and other municipalities. conclusions: the correction of mortality rates based on redistribution of ill-defined causes of death increased the magnitude of the overall cancer mortality in brazil by approximately 10% in 1980 and 5% in 2006. in the inland municipalities no decrease or stability was identified, differently from what was observed in the state capitals. limited scope of prevention actions and lower access to services of cancer diagnosis and treatment for the population living away from large urban centers may partly explain these differences.
