Estudi d'inundabilitat de Calonge

Aquest és un projecte per fer un estudi d’inundabilitat de la zona de Calonge i Sant Antoni de Calonge per tal de reduir l’impacte que aquestes inundacions ocasionen. La realització de l’estudi és necessària ja que les inundacions a la zona són periòdiques i els efectes no disminueixen d’un episodi a l’altre, per tant, cal establir mesures correctores i/o minimitzadores per tal d’evitar la perillositat d’aquests efectes. Es tracta d’un projecte de final de Carrera, de 4rt de Ciències Ambientals, que va ser encarregat per l’Ajuntament de Calonge, l’Octubre del 2005 un cop finalitzats els greus episodis d’inundacions que tants de danys van ocasionar al terme municipal

An MLSA-based online scheme for the rapid identification of Stenotrophomonas isolates

An online scheme to assign Stenotrophomonas isolates to genomic groups was developed using the multilocus sequence analysis (MLSA), which is based on the DNA sequencing of selected fragments of the housekeeping genes ATP synthase alpha subunit (atpA), the recombination repair protein (recA), the RNA polymerase alpha subunit (rpoA) and the excision repair beta subunit (uvrB). This MLSA-based scheme was validated using eight of the 10 Stenotrophomonas species that have been previously described. The environmental and nosocomial Stenotrophomonas strains were characterised using MLSA, 16S rRNA sequencing and DNA-DNA hybridisation (DDH) analyses. Strains of the same species were found to have greater than 95% concatenated sequence similarity and specific strains formed cohesive readily recognisable phylogenetic groups. Therefore, MLSA appeared to be an effective alternative methodology to amplified fragment length polymorphism fingerprint and DDH techniques. Strains of Stenotrophomonas can be readily assigned through the open database resource that was developed in the current study (www.steno.lncc.br/).

Impacte de la crisi econòmica en una destinació de sol i platja: cas Platja d’Aro

La crisi econòmica és un fet molt recent, però pel qual mai s’està preparat. El gran allau de notícies tant en mitjans televisius, com de radio, diaris, etc., els quals en parlen constantment, ha motivat la curiositat per esbrinar si la crisi econòmica està afectant al sector turístic i de quina manera. Com és sabut, des de fa ja uns anys es parla de les destinacions en crisi, d’un turisme de sol i platja en crisi, ja que les noves destinacions estan fent ombra a aquelles que durant els 70 i 80 van tenir un boom i una gran acceptació, la qual cosa fa pensar que la situació actual de la crisi econòmica pot fer agreujar aquest estat de davallada del turisme de masses

Long-term risk of incident type 2 diabetes and measures of overall and regional obesity: the EPIC-InterAct case-cohort study

BACKGROUND Waist circumference (WC) is a simple and reliable measure of fat distribution that may add to the prediction of type 2 diabetes (T2D), but previous studies have been too small to reliably quantify the relative and absolute risk of future diabetes by WC at different levels of body mass index (BMI). METHODS AND FINDINGS The prospective InterAct case-cohort study was conducted in 26 centres in eight European countries and consists of 12,403 incident T2D cases and a stratified subcohort of 16,154 individuals from a total cohort of 340,234 participants with 3.99 million person-years of follow-up. We used Prentice-weighted Cox regression and random effects meta-analysis methods to estimate hazard ratios for T2D. Kaplan-Meier estimates of the cumulative incidence of T2D were calculated. BMI and WC were each independently associated with T2D, with WC being a stronger risk factor in women than in men. Risk increased across groups defined by BMI and WC; compared to low normal weight individuals (BMI 18.5-22.4 kg/m(2)) with a low WC (<94/80 cm in men/women), the hazard ratio of T2D was 22.0 (95% confidence interval 14.3; 33.8) in men and 31.8 (25.2; 40.2) in women with grade 2 obesity (BMI≥35 kg/m(2)) and a high WC (>102/88 cm). Among the large group of overweight individuals, WC measurement was highly informative and facilitated the identification of a subgroup of overweight people with high WC whose 10-y T2D cumulative incidence (men, 70 per 1,000 person-years; women, 44 per 1,000 person-years) was comparable to that of the obese group (50-103 per 1,000 person-years in men and 28-74 per 1,000 person-years in women). CONCLUSIONS WC is independently and strongly associated with T2D, particularly in women, and should be more widely measured for risk stratification. If targeted measurement is necessary for reasons of resource scarcity, measuring WC in overweight individuals may be an effective strategy, since it identifies a high-risk subgroup of individuals who could benefit from individualised preventive action.

Tea consumption and incidence of type 2 diabetes in Europe: the EPIC-InterAct case-cohort study.

BACKGROUND In previous meta-analyses, tea consumption has been associated with lower incidence of type 2 diabetes. It is unclear, however, if tea is associated inversely over the entire range of intake. Therefore, we investigated the association between tea consumption and incidence of type 2 diabetes in a European population. METHODOLOGY/PRINCIPAL FINDINGS The EPIC-InterAct case-cohort study was conducted in 26 centers in 8 European countries and consists of a total of 12,403 incident type 2 diabetes cases and a stratified subcohort of 16,835 individuals from a total cohort of 340,234 participants with 3.99 million person-years of follow-up. Country-specific Hazard Ratios (HR) for incidence of type 2 diabetes were obtained after adjustment for lifestyle and dietary factors using a Cox regression adapted for a case-cohort design. Subsequently, country-specific HR were combined using a random effects meta-analysis. Tea consumption was studied as categorical variable (0, >0-<1, 1-<4, ≥ 4 cups/day). The dose-response of the association was further explored by restricted cubic spline regression. Country specific medians of tea consumption ranged from 0 cups/day in Spain to 4 cups/day in United Kingdom. Tea consumption was associated inversely with incidence of type 2 diabetes; the HR was 0.84 [95%CI 0.71, 1.00] when participants who drank ≥ 4 cups of tea per day were compared with non-drinkers (p(linear trend) = 0.04). Incidence of type 2 diabetes already tended to be lower with tea consumption of 1-<4 cups/day (HR = 0.93 [95%CI 0.81, 1.05]). Spline regression did not suggest a non-linear association (p(non-linearity) = 0.20). CONCLUSIONS/SIGNIFICANCE A linear inverse association was observed between tea consumption and incidence of type 2 diabetes. People who drink at least 4 cups of tea per day may have a 16% lower risk of developing type 2 diabetes than non-tea drinkers.

Avaluació de l'efecte d'aclarida de diferents productes en la varietat de poma Reineta Gris del Canadà amb la finalitat de determinar una estratègia d'aclarida química

Estudi d' una estratègia d’aclarida química per la varietat Reineta Gris del Canadà per garantir una producció de qualitat i reduir l’alternança dels arbres. Les raons de l’estudi eren principalment la poca informació disponible dels productes i dosificacions a utilitzar en l’aclarida de la varietat. En segon lloc l’interès comercial d’algunes empreses del sector per aquesta varietat i per obtenir un producte de qualitat principalment pel calibre de la poma. Per tal d’assolir aquest objectiu principal es van plantejar els objectius concrets: Quantificar el poder aclaridor de tres productes convencionals, NAD, ANA i Carbaryl; testar el poder aclaridor de la BA, ja que tot i ser un producte no registrat se li coneix un efecte aclaridor per altres varietats de poma i provar barreges i aplicacions seqüencials dels productes mencionats
