Journal of Philosophical Logic, 2023 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 ...

Investigation of Cutting Tools and Working Conditions Effects when Cutting Ti-6al-4V using Vegetable Oil-Based Cutting Fluids [PDF]
, 2015 Power consumed in metal cutting is typically converted into heat near the cutting tool edge. Cutting fluids are then provided to a cutting zone in order to improve the tribological characteristics of machining processes and to dissipate the generated ...

Thioester synthesis through geoelectrochemical CO2 fixation on Ni sulfides
Communications Chemistry, 2021 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 ...

British Journal of General Practice, 2010 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

Multi-scale simulation of the nano-metric cutting process [PDF]
, 2010 Molecular dynamics (MD) simulation and the finite element (FE) method are two popular numerical techniques for the simulation of machining processes. The two methods have their own strengths and limitations.

Non-uniform corner cutting [PDF]
, 1988 The convergence of a non-uniform corner cutting process is investigated. It is shown that the limit curve will be differentiable provided the proportions of the corner cuts are kept within appropriate constraints.

Sequential cocatalyst decoration on BaTaO2N towards highly-active Z-scheme water splitting
Nature Communications, 2021 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 ...

Metal cutting modelling SPH approach [PDF]
, 2011 The purpose of this work is to evaluate the use of the smoothed particle hydrodynamics (SPH) method within the framework of high speed cutting modelling. First, a 2D SPH based model is carried out using the LS-DYNA® software.
