Assessing subway network ground borne noise and vibration using transfer function from tunnel wall to soil surface measured by muck train operation
(2019)During the operation of urban subway rail transit system, ground vibrations are generated that transmitted through the ground and cause vibrations in nearby buildings. The operation of these systems can be characterized ... -
Bubble dynamics during degassing of liquids at microgravity conditions
(2006)This work investigates the growth of bubbles generated in a liquid saturated with dissolved CO(2) when its temperature is rapidly and locally raised above the saturation value, still below the boiling point of the test ... -
Bubbles growing in supersaturated solutions at reduced gravity
(2004)This work investigates bubbles growing in a liquid saturated with a dissolved gas when its temperature is locally raised above its saturation value, yet below boiling. Local supersaturation is realized by giving heat pulses ... -
The effect of alveolar mixing on particle retention and deposition investigated by a dynamic single-path model
(2020)A dynamic, single-path model is developed for dry powder transport in the lungs. The model differentiates between particle behavior in the respiratory bronchioles and alveolar ducts on one hand and inside the alveoli on ... -
Methicillin-resistant Staphylococcus aureus in the hospitals of Central Greece
(2001)A total of 250 consecutive Staphylococcus aureus clinical isolates were collected during the period 1999-2000 from the five major hospitals of the district of Thessaly (Central Greece). Thirty seven (14.8%) of the isolates ... -
Optimum design of the entrance of a fishpond laterally to the main stream of an open channel
(2017)In this study, the optimum design of the entrance of a fishpond laterally to the main flow of an open channel was investigated numerically and experimentally. The flow characteristic measurements were realized with the PIV ... -
Oxygen adatom diffusion on the NiO(001) surface by molecular dynamics simulation
(2002)We present results concerning the diffusion processes of O2- adatom on the NiO(0 0 1) surface obtained by molecular dynamics simulations based on a rigid ion potential model. We covered a temperature region from 0.37T(m) ... -
Pm2.5 pollution strongly predicted covid-19 incidence in four high-polluted urbanized italian cities during the pre-lockdown and lockdown periods
(2021)Background: The coronavirus disease in 2019 (COVID-19) heavily hit Italy, one of Europe’s most polluted countries. The extent to which PM pollution contributed to COVID-19 diffusion is needing further clarification. We ... -

Self-similar growth of a gas bubble induced by localized heating: the effect of temperature-dependent transport properties
(2005)A gas bubble growing in a saturated liquid under the action of an internal heat source is studied theoretically as a model problem for the growth of a bubble around a miniature spherical heater submerged in the liquid. In ... -
The sustainable diffusion of renewable energy technologies as an example of an innovation-focused policy
(2005)Renewable energy technologies constitute a techno-economic system that is radically different from conventional systems, in terms of density, structure, regulatory and management practices. Consequently, their incorporation ...
