Published 1999Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Six analytical expressions (four of which have been published recently) for the equation of state of a hard sphere system, together with two different expressions for the molecular diameter, have been tested in order to reproduce molecular dynamics results for pressure and potential energy of the Weeks–Chandler–Andersen reference system for the Lennard-Jones potential. The best choices for the combination of equations of state and molecular diameters in the calculation of those properties are given. It is shown how that choice may differ for different ranges of temperatures and densities, and how there is not a direct relation between the simplicity or complexity of the analytical expressions and their accuracy. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Molecular dynamics results of pressure and potential energy for the reference system of the Weeks–Chandler–Andersen theory applied to two-dimensional fluids have been obtained in a wide range of temperatures and densities. These results are used to test the validity of six different analytical equations of state for hard-disk fluids proposed in the literature (some of which have been published recently), together with two different analytical expressions for the molecular diameter, to describe the properties of the above-mentioned fluids. The best choices for the combination of equations of state and molecular diameters in the calculation of the pressure and potential energy are given. It is shown how that choice may differ for different ranges of temperatures and densities, and how there is not a direct relation between the simplicity or complexity of the analytical expressions and their accuracy. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1365-2222Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Pollen allergy is a common disease causing hayfever in 15% of the population in Europe. Medical studies report that a prior knowledge of pollen content in the air can be useful in the management of pollen-related diseases.Objectives The aim of this work was to forecast daily Poaceae pollen concentrations in the air by using meteorological data and pollen counts from previous days as independent variables.Methods Linear regression models and co-evolutive neural network models were used for this study. Pollen was monitored by a Hirst-type spore trap using standard techniques. The data were obtained from the Spanish Aerobiology Network database, University of Cordoba Monitoring Unit. The set of data includes a series of 20 years, from 1982 to 2001. A classification of the years according to their allergenic potential was made using a K-mean cluster analysis with pollen and meteorological parameters. Statistical analysis was applied to all the years of each class with the exception of the most recent year, which was used for model validation.Results It was observed that cumulative variables and pollen values from previous days are the most important factors in the models. In general, neural network equations produce better results than linear regression equations.Conclusion Co-evolutive neural network models, which obtain the best forecasts (an almost 90%“good” classification), make it possible to predict daily airborne Poaceae pollen concentrations. This new system based on neural network models is a step toward the automation of the pollen forecast process.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1398-9995Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background: Privet pollen rarely accounts for more than 1% of the annual total of daily pollen concentrations measured in a city; however in areas where these trees are widely used as ornamentals the amounts collected may be high enough to cause allergy symptoms. Methods: Air samples taken with volumetric particle samplers Lanzoni VPPS 1000 (Lanzoni s.r.l., Bologna, Italy) show that there are differences in privet pollen concentrations measured in neighbourhoods with a high incidence of privet trees and in those taken at some distance from the source of emission. Results: The results suggest that differences are due to the short dispersal range of the pollen grains once released from the plant, resulting from both the entomophilous nature of the plant and the large size of the pollen grains. Urban design, moreover, may play an important role in impeding pollen grain dispersion if the air cannot flow freely through long, narrow avenues. Another important consideration is that the last stages of the flowering period of privet overlaps with the flowering period of olive trees, the main allergen in the area. The fact that the two pollen types share common allergens means that there may be a cross-reaction between olive tree pollen and privet pollen. Conclusions: Privet pollen should be considered as a potential causative agent of local allergy problems in areas where its presence is extensive and is in combination with other allergens.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1254Keywords: Key words Inversion layers ; Winter phenomena ; Cupressus pollen ; Solid suspended particlesSource: Springer Online Journal Archives 1860-2000Topics: GeographyPhysicsNotes: Abstract Winter is not traditionally considered to be a risky season for people who suffer from pollen allergies. However, increasing numbers of people are showing symptoms in winter. This prompted our investigation into the levels of solid material in the air, and some of the meteorological phenomena that allow their accumulation. This study showed a possible relationship between the phenomenon of thermal inversion, which occurs when very low temperatures, cloudless skies and atmospheric calms coincide, and an increase in the concentration of solid material in the atmosphere. Frequently, this situation is associated with other predictable phenomena such as fog, dew and frost. This may allow a warning system to be derived for urban pollution episodes. The effect caused by parameters such as wind and rainfall was also analysed. Solid material was differentiated into non-biological material from natural and non-natural sources (e.g. soot, dust, sand, diesel exhaust particles, partially burnt residues) and biological material. The latter mainly comprises pollen grains and fungal spores. Owing to its abundance and importance as a causal agent of winter allergies, Cupressaceae pollen was considered separately.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1432-1254Keywords: Key words Urticaceae pollen ; Meteorological factors ; Southwest SpainSource: Springer Online Journal Archives 1860-2000Topics: GeographyPhysicsNotes: Abstract The influence of meteorological factors on daily Urticaceae pollen counts were studied in Córdoba (southwest Spain) in 1996 and 1997. The daily Urticaceae pollen concentrations were obtained by using a Hirst-type volumetric sampler, and meteorological data were obtained from the Córdoba airport, located near the sampling site. The highest correlation between pollen concentration and meteorological parameters was obtained during non-rainy seasons. Temperature was found to be the most important meteorological parameter influencing pollen counts in spring, as temperature is the main reason for the increase of pollen concentration in the atmosphere. In autumn, humidity was another important parameter influencing pollen counts. Rain, however, did not appear to be significant. The influence of the pollen concentration of the 2 previous days and the pollen concentration of the previous day has been studied. During periods with low precipitation, the pollen concentration of the previous day was a useful predictor of Urticaceae pollen concentrations for the following day.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1254Keywords: Key words Cupressaceae airborne pollen ; Biometeorology ; Allergenic pollen ; Pollen forecastSource: Springer Online Journal Archives 1860-2000Topics: GeographyPhysicsNotes: Abstract Daily variations in Cupressaceae pollen counts were analysed, together with climatic variables in the southwest of Spain, in order to understand the bioclimatic variables affecting Cupressaceae flowering in a Mediterranean climate. The study was carried out using the Spanish Aerobiology Network recommendations, using a Burkard Hirst-type spore trap. Regression analyses were applied to the pollen counts of the winter months of 13 consecutive years. The regression analysis applied to each year indicated that temperature is the most important variable to include in the model. Temperature affected the pollen counts differently according to the yearly climatic trend. During the coldest years, pollen counts depended on the minimum temperature, while in the warmest ones they were affected by higher temperatures. However, during the driest years, pollen counts depended more on the humidity level, while in the wettest years they depended more on the hours of sunshine.Type of Medium: Electronic ResourceURL: -
