On the 29th of June, 2009 the derailment of a rail-tanker containing liquefied petroleum gas (LPG) in the Viareggio station produced a large candle snuffer big w cloud of flammable vapours, which ignited in a flash-fire, causing 31 fatalities and extensive property damage.The literature models applicable to the simulation of flash fires differ for
In this paper, a CMOS Class-J Doherty power amplifier (PA) integrating a Class-G driver and an Impedance-Modulated-Quadrature-Transformer (IMQT) to enhance back-off efficiency for multimode operations is presented.The Class-J Doherty PA utilizes a second harmonic termination to improve its efficiency.To further augment efficiency at deep back-off o
Abstract The use of chatbots is becoming widespread as they offer significant economic opportunities.At the same time, however, customers seem to prefer interacting with human operators when making inquiries and as a result are not as cooperative with chatbots aftermath cabernet sauvignon 2017 when their use is known.This specific situation creates
Abstract Background Equity in access to quality healthcare is a fundamental human right.Yet studies demonstrate that some people receive preferential treatment while others are discriminated against.Wasta is a prevalent strategy whereby personal connections are used for influence and may result in gaining unfair advantages over others.This study ai
The motion of passive admixture of spherical particles in the stationary hydrodynamic field of a swirling flow is studied.A spherical particle of a given mass in the hydrodynamic envox stock field of a swirling flow is located on a certain circular orbit, where the centrifugal caroline gardner cards sale force is compensated by the radial drag forc
