We present the results of Air Pollution and Health: A European Approach 2 (APHEA2) project on short-term effects ambient particles mortality with emphasis effect modification. used daily measurements for particulate matter less than 10 μm in aerodynamic diameter (PM10) and/or black smoke from 29 cities. considered confounding other pollutants as well meteorologic chronologic variables. investigated several variables describing cities’ pollution, climate, population, geography potential...
We investigated the short-term effects of air pollution on hospital admissions for chronic obstructive pulmonary disease (COPD) in Europe. As part a European project (Air Pollution and Health, Approach (APHEA)), we analysed data from cities Amsterdam, Barcelona, London, Milan, Paris Rotterdam, using standardized approach to eligibility statistical analysis. Relative risks daily COPD were obtained Poisson regression, controlling for: seasonal other cycles; influenza epidemics; day week;...
STUDY OBJECTIVE: To review the issues and methodologies in epidemiologic time series studies of daily counts mortality hospital admissions illustrate some methodologies. DESIGN: This is a paper with an example drawn from elderly Cleveland, Ohio, USA. MAIN RESULTS: The central issue control for seasonality. Both over under are possible, use diagnostics, including plots, necessary. Weather dependence probably non-linear, adequate methods necessary to adjust this. In categorical variables...
In this paper, we present preliminary results of the IPL project No. 198 “Multi-scale rainfall triggering models for Early Warning Landslides (MUSE).” particular, perform an assessment geotechnical and hydrological parameters affecting occurrence landslides. The aim study is to improve reliability a physically based model high resolution slope stability simulator (HIRESSS) forecasting shallow soil characterization have been tested in Northern Tuscany (Italy), along Apennine chain, area that...
Abstract. We propose an original approach to develop rainfall thresholds be used in civil protection warning systems for the occurrence of landslides at regional scale (i.e. tens thousands kilometres), and we apply it Tuscany, Italy (23 000 km2). Purpose-developed software is define statistical intensity–duration by means automated standardized analysis data. The automation standardization brings several advantages that turn have a positive impact on applicability operational systems....
Abstract Climate change linked to human activities is affecting natural systems, increasing frequency and severity of water-related hazards. The issue climate pushes tackle the expected risks in water sector through a comprehensive global view, with revision paradigms considered as drivers resources development. Based on evolution these Italy main characteristics an adaptive approach other changes are discussed relatively infrastructures, legislative institutional frameworks. objective...
We describe a simple theory of diffusion-limited-aggregation cluster growth which relates the large-scale shape to its fractal dimension. present results computer simulation for DLA clusters grown with anisotropic sticking rules provide strong confirmation our model in two dimensions. New universal exponents are predicted and found. also able obtain good estimates dimension ordinary DLA.
Conformational disorder plays an important role in determining the electronic properties of conjugated polymers. To obtain a better theoretical description and extent conformational disorder, we derive π electron correlation length bond terms effective torsional potential geometry polymer chains. These quantites are related to conjugation lengths persistence chain, which computed for polyacetylene, polydiacetylene, polythiophene, polypyrrole. In spite uncertainties parameters these...
Thin polymeric coating layers are often used to improve the barrier properties of packaging structures and container walls. We study how local flaws in affect overall permeation such systems. find that many small ‘‘holes’’ a layer much more effective compromising system than few large with same total area.
Abstract. This work proposes a methodology to compare the forecasting effectiveness of different rainfall threshold models for landslide forecasting. We tested our with two state-of-the-art models, one using intensity–duration thresholds and other based on cumulative thresholds. The first model identifies by means software program called MaCumBA (MAssive CUMulative Brisk Analyzer) (Segoni et al., 2014a) that analyzes rain gauge records, extracts intensity (I) duration (D) rainstorms...
The objective of this study was to evaluate the potential practical application unmanned aerial vehicles and RGB vegetation indices (VIs) in monitoring a coffee crop. conducted an experimental field over 12-month period. An digital camera coupled UAV used. Nine VIs were evaluated study. These subjected Pearson correlation analysis with leaf area index (LAI), subsequently, higher R2 values selected. LAI estimated by plant height crown diameter obtained imaging, which correlated these measured...
Short-term effects of air pollution on daily mortality in eight western and five central-eastern European countries have been reported previously, as part the APHEA project. One intriguing finding was that were lower cities. The analysis used sinusoidal terms for seasonal control polynomial meteorologic variables, but this is a more rigid approach than currently accepted method, which uses generalized additive models (GAM). We therefore reanalyzed original data to examine sensitivity results...
