The observation of high hypotonicity manipulating cell division

open access: yesHeliyon, 2019
We report a morphological manipulation of cell division which was achieved by changing the environment from isotonic to highly hypotonic. Cells at telophase were observed to undergo a morphological reversal to anaphase, with the contractile ring being ...

Multi-Scale Modelling of a Solar Reactor for the High-Temperature Step of a Sulphur-Iodine-Based Water Splitting Cycle [PDF]

open access: yes, 2011
The 3-step sulphur-iodine-based thermochemical cycle for splitting water is considered. The high temperature step of the closed-material cycle consists of evaporation, decomposition, and reduction of sulphuric acid to SO2 using concentrated solar process

Non-Local Vectorial Internal Variables and Generalized Guyer-Krumhansl Evolution Equations for the Heat Flux

open access: yesEntropy, 2023
In this paper, we ask ourselves how non-local effects affect the description of thermodynamic systems with internal variables. Usually, one assumes that the internal variables are local, but that their evolution equations are non-local, i.e., for ...

Heat transport in mesoscopic systems [PDF]

open access: yesSuperlattices and Microstructures, 1998
Phonon heat transport in mesoscopic systems is investigated using methods analogous to the Landauer description of electrical conductance. A "universal heat conductance" expression that depends on the properties of the conducting pathway only through the mode cutoff frequencies is derived.

Transport outlook 2009: Globalisation, crisis and transport [PDF]

open access: yes, 2009
This second ITF Transport Outlook continues building towards a full-fledged Transport Outlook, building upon the first Outlook (JTRC, 20081). The 2008 Outlook investigated the relation between expected GDP evolution and the demand for road transport ...

An industry-scale modeling for the turbulence agglomeration of fine particles

open access: yesAdvances in Mechanical Engineering, 2015
Turbulence-induced agglomeration of fine particles/droplets in aerosol is important in various industrial and natural processes. Despite abundant theoretical and numerical studies on turbulent collision kernels, convincing numerical methods for industry ...

Prediction of Leidenfrost Temperature in Spray Cooling for Continuous Casting and Heat Treatment Processes

open access: yesMetals, 2020
Spray cooling of hot steel surfaces is an inherent part of continuous casting and heat treatment. When we consider the temperature interval between room temperature and for instance 1000 °C, different boiling regimes can be observed.

Numerical Simulation of Heat Transport Problems in Porous Media Coupled with Water Flow Using the Network Method

open access: yesEnergies, 2021
In the present work, a network model for the numerical resolution of the heat transport problem in porous media coupled with a water flow is presented. Starting from the governing equations, both for 1D and 2D geometries, an equivalent electrical circuit
