Throughout the manuscript, the word ‘metastability’ refers to a sample condition describing a stable state of a dynamical system other than the system’s state of least energy. Depending on the context, the term applies both to phase equilibria and electronic defect states. The starting point ...
Also, it has been found that softer bitumen is more susceptible to oxidation of ageing than a harder (stiffer) bitumen [66]. As for the MSCR, the non-recoverable compliance Jnr and average percent recovery %R are the main indices. It can be concluded that after even short-term ageing, ...
The deformation transient following large subduction zone earthquakes is thought to originate from the interaction of viscoelastic flow in the asthenospheric mantle and slip on the megathrust that are both accelerated by the sudden coseismic stress chang
Currently, there are several different thermodynamic hydrate inhibitors that one has available to choose from. One could choose to use an oxygenate, such as methanol, or a glycol, such as mono-ethylene glycol (MEG) or diethylene glycol (DEG). But what determines the inhibitors hydrate suppression...
For the initiation term, we take twice the average value of the end contributions, whereas for the next-neighbor term, we have to take into account that the quadruplets that are symmetric under complementary inversion (e.g., AT/TA, TA/AT, CG/GC, and GC/CG for DNA/DNA) have half of...
The most fitting linguistic term that can and should be used to name this “stuff” will obviously be heat, or if we want to be a little more formal, quantity of heat. 2.2. Heat as a Force of Nature These are the opening lines of Sadi Canot’s book, Réflexions sur la puissance ...
Like I say we'll see, but from where I'm sitting it applies to you - it is way too early for me to tell whether this will be a success, you think you know the future and I doubt you do. This is a just a propsed new type of large, very complex, inefficient battery and tim...
