Effective management of heat transfer fluid flash point temperatures using a light-ends removal kit (LERK)

open access: yesCase Studies in Thermal Engineering, 2014
Heat transfer fluids (HTF) need to be regularly sampled to assess the extent of thermal degradation, oxidative state, the accumulation of short-chained light-ends and contamination by intrinsic or extrinsic particles.

Heat transfer system safety: Comparing the effectiveness of batch venting and a light-ends removal kit (LERK)

open access: yesCase Studies in Thermal Engineering, 2014
Heat transfer fluids (HTF) should be analysed at least once per year to determine the extent of thermal degradation. Under normal operating conditions, mineral-based HTFs will thermally degrade and the bonds between hydrocarbons break to form shorter ...

Vapors produced by electronic cigarettes and e-juices with flavorings induce toxicity, oxidative stress, and inflammatory response in lung epithelial cells and in mouse lung. [PDF]

open access: yesPLoS ONE, 2015
Oxidative stress and inflammatory response are the key events in the pathogenesis of chronic airway diseases. The consumption of electronic cigarettes (e-cigs) with a variety of e-liquids/e-juices is alarmingly increasing without the unrealized potential

Scattering from the weakly absorbing cylindrical capsule in the WKB approximation

open access: yesMaterials Science for Energy Technologies, 2023
In this work, the Wentzel-Kramers-Brillouin (WKB) approximation is used to determine the form factor of a particle having a refractive index close to the outer medium. The analytical expression of the light scattering amplitude by a cylinder with conical

Dynamics of two liquids in a non-uniformly rotating horizontal cylinder [PDF]

open access: yesE3S Web of Conferences, 2023
Controlling the shape of the interfacial boundary is an important technological task. The effect of rotation velocity modulation on the interface between light viscous and denser low viscosity fluid in a rotating horizontal cylinder is studied ...

Morality, Voluntary Laws, and State Neutrality

open access: yesLaws, 2023
Kantian political philosophies stress that a state ought to be “neutral” (Rawls), “minimal” (Nozick), or “public” (Ripstein’s Kant), as part of its duty to respect its citizens’ freedom to pursue whatever ends these citizens find valuable.

ResSKNet-SSDP: Effective and Light End-To-End Architecture for Speaker Recognition

open access: yesSensors, 2023
In speaker recognition tasks, convolutional neural network (CNN)-based approaches have shown significant success. Modeling the long-term contexts and efficiently aggregating the information are two challenges in speaker recognition, and they have a critical impact on system performance. Previous research has addressed these issues by introducing deeper,
