On pressure and temperature waves within a cavitation bubble [PDF]

open access: yes, 2009
The presented work is about the detailed pressure, temperature and velocity distribution within a plane, cylindrical and spherical cavitation bubble. The review of Plesset & Prosperetti (1977) and more recently the review of Feng & Leal (1997) describe ...

Non-visual effects of the light source “correlated color temperature” on electroencephalographic spectral power, sleepiness and neurobehavioral performance

open access: yesSalāmat-i kār-i Īrān, 2020
Background and aims: Fatigue and sleepiness (decreased alertness), in addition to a negative impact on performance and quality of work, are considered as one of the leading causes of human error and accidents in work environments.

Photostop [PDF]

open access: yes, 2013
The use of photodissociation to produce cold, slow molecules from a molecular beam of cold, fast molecules is dubbed “photostop”. The essence of the scheme is thus: a pulsed molecular beam of a precursor molecule AB seeded in a noble carrier gas is ...

Spatial and temporal behavior of the plasma parameters in a pulsed magnetron discharge

open access: yes, 2002
We demonstrate the evolution of the electron, energy distribution and the plasma parameters in a high-density plasma in a pulsed magnetron discharge. The high-density plasma is created by applying a high power pulse (1–2.4 MW) with pulse length 100 μs ...

Simplified model for polyurethane foaming in porous media

open access: yes, 2017
Purpose The purpose of the study is to present a simplified model to replace the complicated foaming simulations for investigating the liquid polyurethane behavior just before solidification. Design/methodology/approach This model is inspired from the

Ultrafast dynamics in InAs quantum dot and GaInNAs quantum well semiconductor heterostructures

open access: yes, 2007
The quantum confined Stark effect (QCSE) and ultrafast absorption dynamics near the bandedge have been investigated in p-i-n waveguides comprising quantum confined heterostructures grown on GaAs substrates, for emission at 1.3um.

Distribución y condiciones ambientales asociadas al comportamiento del delfín bufeo (Tursiops truncatus) y el delfín manchado (Stenella attenuata) (Cetacea: Delphinidae) en el Golfo Dulce, Costa Rica

open access: yesRevista de Biología Tropical, 2007
Las características del hábitat que influyen en las especies animales varían de un lugar a otro. Al mismo tiempo, toda especie es rodeada por una serie de factores ambientales que interactúan entre sí, pero la influencia que una característica ambiental ...

Quantitative Assessment of Parallel Strand Bamboo Damage Subjected to Realistic Multi-Scenario Fire Exposure

open access: yes工程科学与技术
ObjectiveConventional methods for assessing fire-induced damage to structural materials, which predominantly rely on standard fire curves like ISO-834, face significant limitations when applied to real fires characterized by highly variable and uncertain
