An integrated package for modelling and mapping urban traffic emissions and air and acoustic quality

2005

Urban activities and traffic movements have an important impact on the acoustic level and air pollution. The aim of the present paper is to assess the improvement of an environmental territorial information system, developed in 2003, useful as a decision support for town-planning and territorial management. The system born as a data base and as a tools of management for environmental problems is now improved and is able to calculate the noise levels and the correlate CO values. Since an urban area could be analyzed at a macro-scale level also the evaluation is at a macro scale level. Thanks to its flexibility, the modular system allows to meet the demands of a wide range of applications.

Interaction between surface plasmon polaritons and molecules in strong coupling limit

2016

Miniaturization of optical elements and their integration to electronic circuits is limited by diffraction limit. It was realized that light being coupled to surface plasmons (SP) can overcome this limit. Employing also optically active molecules in combination with SPs can drive optical circuits to nm-scale and add functionalities. For efficient performance of plasmonic elements involving fluorescent dye molecules investigation of physics behind their interaction is of high priority. In this thesis interaction between surface plasmon polaritons (SPPs) and different dye molecules has been studied, especially within strong coupling limit, which brings in totally new physical properties in th…

Hydrogen plasma induced photoelectron emission from metal surfaces

2018

Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface work function of the wall material. In this work, the plasma induced photoelectron emission has been studied with different ion sources. The emission depends on the mechanical design of the plasma device, plasma heating method and the discharge power (density). Parametric studies include the quantifying of the emission from different metal surfaces, commonly used as plasma facing materials in ion sources, as well as alkali metal covered surfaces. Experimental studies sugges…

Simulation with a Torque Dynamometer of Pollutants Emission from Vehicles Near Urban Cross-Road

2002

Nowadays, the influence of the vehicular traffic on the degradation of urban atmosphere is focused on by researchers belonging to different fields in view of its prime importance for public health. The control of exhaust gases emission is primary in order to keep air pollution below the specified limits of the laws in force. In previous works the “medium car” characterises a country in modelling a pollutant in urban areas. This is the central parameter of a forecasting model proposed by Pignato and LoMastro, of pollutant concentration near urban cross-road with traffic lights in continue queue and platoon flow. The proofs have been carried on two classes of displacement vehicles and four cl…

Medical masks and Respirators for the Protection of Healthcare Workers from SARS-CoV-2 and other viruses

2020

The use of medical masks and respirators as personal protective equipment is pivotal to reducing the level of biological hazard to which healthcare workers are exposed during the outbreak of highly diffusible pathogens, such as the recent novel coronavirus SARS-CoV-2. Unfortunately, during this pandemic, supplies are rapidly running out worldwide, with potential consequences for the rate of occupational infections. Also, knowledge about specific characteristics of respirators is of utmost importance to select the proper type according to the clinical setting. A wide variety of literature is available on the topic, but mostly based on Influenza viruses infection models. Clinical evidence on …

Measurement of dielectron production in central Pb-Pb collisions at √sNN = 2.76 TeV

Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. The first measurement of dielectron (e + e −) production in central (0 – 10 %) Pb – Pb collisions at √sNN=2.76TeV at the LHC is presented. The dielectron invariant-mass spectrum is compared to the expected contributions from hadron decays in the invariant-mass range 0 < mee < 3.5 GeV / c2. The ratio of data and the cocktail of hadronic contributions without vacuum ρ0 is measured in the invariant-mass range 0.15 < mee < 0.7 GeV / c2, w…

Occlusion-derived baculovirus: interaction with human cells and evaluation of the envelope protein P74 as a surface display platform.

2008

To develop complementary baculovirus-based tools for gene delivery and display technologies, the interaction of occlusion-derived baculovirus (ODV) with human cells, and the functionality of the P74 ODV envelope protein for display of the IgG-binding Z domains (ZZP74) were evaluated. The cellular binding of ODV was concentration-dependent and saturable. Only minority of the bound virions were internalized at both 37 and 4 degrees C, suggesting usage of direct membrane fusion as the entry mode. The intracellular transport of ODV was confined in vesicular structures peripheral to the plasma membrane, impeding subsequent nuclear entry and transgene expression. Transduction of ODV was not rescu…
