  • a psychrometric model to assess the Biological Decay of the sars cov 2 virus in aerosols
    PeerJ, 2021
    Co-Authors: Clive B Beggs, E J Avital
    Abstract:

    There is increasing evidence that the 2020 COVID-19 pandemic has been influenced by variations in air temperature and humidity. However, the impact that these environmental parameters have on survival of the SARS-CoV-2 virus has not been fully characterised. Therefore, an analytical study was undertaken using published data to develop a psychrometric model to assess the Biological Decay rate of the virus in aerosols. This revealed that it is possible to describe with reasonable accuracy (R2 = 0.718, p < 0.001) the Biological Decay constant for the SARS-CoV-2 virus using a regression model with enthalpy, vapour pressure and specific volume as predictors. Applying this to historical meteorological data from London, Paris and Milan over the pandemic period, produced results which indicate that the average half-life of the virus in aerosols outdoors was in the region 13-22 times longer in March 2020, when the outbreak was accelerating, than it was in August 2020 when epidemic in Europe was at its nadir. However, indoors, this variation is likely to be much less. As such, this suggests that changes in virus survivability due the variations in the psychrometric qualities of the air might influence the transmission of SARS-CoV-2.

Therefore an analytical study was undertaken using published data to develop a psychrometric model to predict the Biological Decay rate of the virus in aerosols. This revealed that it is possible to predict with a high degree of accuracy (R2 = 0.718, p<0.001) the Biological Decay constant for SARS-CoV-2 using a regression model with enthalpy, vapour pressure and specific volume as predictors. Applying this to historical meteorological data from London, Paris and Milan over the pandemic period, produced results which indicate that the average half-life of the virus in aerosols was in the region 13-21 times longer in March 2020, when the outbreak was accelerating, than it was in August 2020 when epidemic in Europe was at its nadir. As such, this suggests that changes in virus survivability due the variations in the psychrometric qualities of the air might influence the transmission of COVID-19.

  • discrete time model for chemical or Biological Decay in chaotic flows reentrance phase transitions
    Physical Review E, 2005
    Co-Authors: I J Benczik
    Abstract:

    We consider a discrete time model of advection, reaction, and diffusion on a lattice to investigate the steady-state spatial structure of chemically Decaying substances. The time discretization of the dynamics has a considerable impact on these structures. Additional smooth-filamental phase transitions, nonexistent in the continuous-time description, appear. We show how these structures and their scaling properties depend on the time step of the discrete dynamics. Exploiting the analogies of this discrete model with the logistic map, some general features are discussed.

  • a case study the evaluation of Biological Decay of a historical hayloft in rendena valley trento italy
    International Biodeterioration & Biodegradation, 2014
    Co-Authors: Sabrina Palanti, Nicola Macchioni, Roberto Paoli, Elisabetta Feci, Francesco Scarpino
    Abstract:

    Abstract The paper describes the evaluation of Biological Decay of structural timber elements of an ancient hayloft in order to obtain a classification of Decay of each timber beam preliminary to the restoration works. The building, a medieval hayloft, is an important artefact for local cultural heritage, because it represents one of the oldest evidences of the alpine vernacular architecture in the beginning of XIV century in Rendena valley, an alpine valley close to Trento (North-Eastern Italy). The building is characterised by a basement made of masonry (stone and bricks) used as a cattle shed, and two stories for hay conservation completely wooden made, up to the roof, covered with wooden shingles. The building as a whole has maintained the initial function of livestock farming until a few years ago, then the last owner sold the building to the municipality of Caderzone that decided to transform it in a museum regarding the ancient agricultural life in the valley. The analysis was performed in accordance with the Italian standard UNI 11119:2004 concerning the in situ inspection of timber structures in historical buildings. The techniques used during the analysis were: visual inspection, percussion with a hammer, resistographic drilling, measurement of wood moisture content in order to obtain detailed information on Biological Decay to define the wood restoration, renovation and remedial treatments.

  • Solid state fermentation a valid alternative for environmental control
    2021
    Co-Authors: Tiso Nicola, Polcaro Chiara, Galli Emanuela, Ragažinskienė Ona, Snieškienė Vilija, Stankevičienė Antanina, Stankevičius Mantas, Maruška Audrius, Drevinskas Tomas, Bartkuvienė Violeta
    Abstract:

    Recently the use of microorganisms, such as white-rot fungi, through Solid State Fermentation (SSF) processes has been seriously investigated. SSF has shown much promise in the development of several bioprocesses and products. White rot fungi seem to be particularly interesting for environmental applications, due to their ability totolerate and/or degrade high concentrations of pollutants for their chemical transformation into less hazardous compound. The wood preservativeshave been extensively used in the last few decades to enhance the life expectancy of woody materials for external uses against natural and Biological Decay, but the popular waste disposal options available for these expended materials nowadays, such as burning and land filling, are not acceptable due to economical, healthand environmental concerns. The development of alternative and environmental friendly methods for disposal of these waste materials is of major importance. This presentation discusses a novel approach for bioremediation of creosote-treated railways wood sleepers by Solid State Fermentation of white-rot fungi and the possibility to combine it sequentially with phytoremediationBiochemijos katedraBotanikos sodasVytauto Didžiojo universiteta
