Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]
In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

Numerical and analytical modeling of orthogonal cutting : The link between local variables and global contact characteristics [PDF]
The response of the tool–chip interface is characterized in the orthogonal cutting process by numerical and analytical means and compared to experimental results. We study the link between local parameters (chip temperature, sliding friction coefficient,

AbstractIn this paper we use proof-theoretic methods, specifically sequent calculi, admissibility of cut within them and the resultant subformula property, to examine a range of philosophically-motivated deontic logics. We show that for all of those logics it is a (meta)theorem that the Special Hume Thesis holds, namely that no purely normative ...

Cutting Forces Modeling in Finish Turning of Inconel 718 Alloy with Round Inserts [PDF]
In turning, the applied forces have to be known as accurately as possible, especially in the case of difficult-to-cut materials for aircraft workpieces finishing operations.

Thioester synthesis through geoelectrochemical CO2 fixation on Ni sulfides
Thioesters are often suggested to be key intermediates in primordial metabolism, but prebiotic CO2 fixation routes to thioesters remain elusive. Here, the authors show nickel sulfide, partially reduced to Ni(0) with realistic geoelectric potentials ...

There are not many people who would admit that, in their field, there should be cuts. I don't think I am brave or clever enough to be the odd one out. So here it is: I am against cuts in health care (the term ‘health care’, in my view, does not include management and administration — in these areas I would cut generously). Why? Because money is already

Sequential cocatalyst decoration on BaTaO2N towards highly-active Z-scheme water splitting
Activation of narrow-bandgap photocatalysts holds key to applicable solar-to-hydrogen energy conversion. Here, the authors demonstrate effective sequential cocatalyst decoration for such narrow-bandgap photocatalysts to realise highly-efficient hydrogen ...
