Lecture ethnologique d’un lieu saint connu depuis le viiie siècle

Abstract: C’est un lieu commun que de parler du Japon comme d’un pays où tradition et modernité se c toient et s’épousent de fa ons extrêmement diverses. Ce déchiffrage spontané du quotidien s’applique à tous les domaines de la vie et à tous ses aspects. Se promener en ville, entrer dans une auberge traditionnelle, visiter une maison, sa cuisine, sa salle de bain, ses toilettes, passer le jour de l’an en famille, autant d’occasions, de lieux de vie où se devine l’entrecroisement complexe d’un faisceau ...

Abstract: objective: to assess the impact of a smoke-free workplace policy in a company. method: the impact of the implementation of a smoke-free workplace policy was assessed between october 2001 and february 2003 in a company with 184 employees. two surveys of the entire staff were performed, one before the implementation of the new policy and the other 14 months after. results: both passive exposure to tobacco smoke and tobacco consumption among smokers decreased. the proportion of workers free of tobacco smoke exposure at their workplace increased from 32% to 84% (p < 0.001) and, among smokers, the mean daily consumption of cigarettes was reduced by 7.3 cigarettes (p = 0.049). conclusions: demarkation of areas where smoking is allowed not only reduces passive exposure to tobacco smoke at the workplace but also seems to encourage smokers to quit smoking or to reduce tobacco consumption.

Abstract: Objetivo: Evaluar el impacto de la implantación de una política integral de trabajo libre de humo en una empresa. Método: Se evaluó el impacto de la implantación de una política integral de trabajo libre de humo entre octubre de 2001 y febrero de 2003 en un centro de 184 trabajadores mediante dos encuestas dirigidas a toda la plantilla, una al comienzo y otra 14 meses después. Resultados: Se redujo tanto la exposición pasiva al humo del tabaco como el consumo de cigarrillos entre las personas que continuaban fumando. La proporción de personas no expuestas al humo del tabaco ambiental en el trabajo aumentó del 32 al 84% (p < 0,001) y el consumo medio de cigarrillos entre las que continuaban fumando se redujo en 7,3 diarios (p = 0,049). Conclusiones: La delimitación de las áreas donde se permite fumar no sólo reduce la exposición pasiva al humo del tabaco en el centro de trabajo sino que también podría animar a los fumadores a dejar de fumar o reducir el consumo.

LA MAXIMIZACIóN DEL BENEFICIO EN LAS EMPRESAS DEPURADORAS DE AGUAS RESIDUALES: EL CASO DE VALENCIA (ESPA?A)
BROTONS MARTíNEZ,JOSé MANUEL;
Estudios Gerenciales , 2011,
Abstract: the main purpose of this paper is to design a new way to maximize the profit of wastewater treatment plants (wwtp). the establishment of multiple goals impedes their simultaneous achievement. as a result, it will be enough to achieve a certain degree of satisfaction of each goal. sometimes this approach can be extremely difficult, so minor violations of some restrictions are exceptionally allowed. fuzzy goal-based scheduling can be considered a suitable tool for these kinds of problems. in short, wwtps will have a suitable tool for achieving profit maximization, and, at the same time, there will be a new system to measure efficiency in the sector.

Abstract: El estudio propone un sistema de maximización de beneficios de una estación depuradora de aguas residuales (EDAR). La presencia de objetivos múltiples impide su consecución simultánea, por lo que se considerará suficiente la consecución de un determinado grado de satisfacción para cada uno de ellos. En ocasiones, resulta muy complicado este último planteamiento, por lo que se permitirán excepcionalmente ciertas violaciones de algunas restricciones, lo que permite concluir que la programación por objetivos borrosa puede ser un instrumento adecuado para este tipo de problemas. En consecuencia, las EDAR tendrán una herramienta precisa para conseguir la maximización de sus beneficios al que se a ade un nuevo sistema de medición de la eficiencia en el sector.
Climate Change or Land Use Dynamics: Do We Know What Climate Change Indicators Indicate?

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0018581
Abstract: Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indicators of climate change impacts that are based on the optimal thermal environment and average latitude of the distribution of bird species present at local communities. We used multiple regression models to relate the variation in climate change indicators to: i) environmental temperature; and ii) three landscape gradients reflecting important current land use change processes (land abandonment, fire impacts and urbanization), all of them having forest areas at their positive extremes. We found that, with few exceptions, landscape gradients determined the figures of climate change indicators as strongly as temperature. Bird communities in forest habitats had colder-dwelling bird species with more northern distributions than farmland, burnt or urban areas. Our results show that land use changes can reverse, hide or exacerbate our perception of climate change impacts when measured through community-level climate change indicators. We stress the need of an explicit incorporation of the interactions between climate change and land use dynamics to understand what are current climate change indicators indicating and be able to isolate real climate change impacts.
Polyphenol extraction from grape wastes: Solvent and pH effect  [PDF]

Abstract:

World wine industry transforms 10% - 25% of raw grapes into residues, mainly represented by lees, grape marcs, seeds and stems. These by-products are a rich source of polyphenols and therefore they can be used to produce new added value products. The aim of this work wasto determine the best process conditions(treatment time, % of ethanol and pH of the solvent)during solid-liquid extraction of polyphenolsfrom grape marcs, by analyzing the phenolic content of the extracts, namely: total polyphenol content, flavanols, flavonols, phenolic acids and anthocyanins. Antioxidant activity of the extracts was also determined. An extraction time of two hours was enough since longer times did not increase process yields. Best extraction yields were obtained for 75% ethanol solutions. Basic pH led to better yields in extracting media with low percentage of ethanol, whereas acid pH presented better extraction yields in extracting media with high percentage of ethanol. Among all the polyphenols extracted, anthocyanins were themost abundant representing over 40% of the total. In general, the best process conditions were 2 h ofextraction in a 75% EtOH liquid mixture at pH =2.

THORACOSCOPIC LOBECTOMY – TECHNICAL ASPECTS

Abstract: Minimally invasive lung resection procedures are more and more used in current practice all over the world and stand for reduced postoperative morbidity and similar long term outcome. Technically speaking, there is a large variability of practice among surgeons but there are some certain things in which all agree. We present the surgical technique that we used for more than 400 thoracoscopic lobectomies in the last 5 years. Although no prospective, randomized series have compared thoracoscopic lobectomy with conventional approaches, a sufficient number of single-institution and multiinstitution series have been published to conclude that thoracoscopic lobectomy is a reasonable strategy for patients with clinical stage I lung cancer
