The effect that the infill orientation angle has on strain-rate dependence of yield stress for material extrusion additive manufactured (ME-AM) PolyLactic Acid (PLA) was investigated. Symmetric angle-ply stacking sequences were used to produce ME-AM tensile test samples. Measured stresses compensated voided structure, typical components. Furthermore, molecular and stretch macroscopically assess...

We consider the problem of (1 + 1)-dimensional quantum gravity coupled to particles. Working with the canonically reduced Hamiltonian, we obtain its post-Newtonian expansion for two identical particles. We quantize the (1 + 1)-dimensional Newtonian system first, after which explicit energy corrections to second order in c−1 are obtained. We compute the perturbed wavefunctions and show that the ...

In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...

The post-Newtonian mean anomaly advance as further post-Keplerian parameter in pul-sar binary systems. Abstract The post-Newtonian secular rate of the mean anomaly ˙ M has been worked out for a two-body system in the framework of the General Theory of Relativity. The possibility of using it as a further post-Keplerian parameter in pulsar binary systems is examined. The resulting effect is almos...

A computational fluid dynamics simulation study has been carried out for unsteady laminar flow in a planar 2D T-junction, using non-Newtonian viscoelastic fluids with characteristics similar to those of blood. In the large blood vessels, blood can be modelled as a Newtonian fluid, however in smaller vessels it exhibits non-Newtonian behaviour, showing a shear-thinning viscosity and, additionall...

Although there is abundant evidence that a rich microflora exists at the bottom of the ocean, in deep oil well brines, and in other habitats characterized by high pressure (cf. ZoBell, 1946), no clear understanding has been reached concerning the influence of pressure on the growth, viability, and metabolism of the organisms in such environments. The results of older (Certes, 1884a,b,c; Regnard...

the excellent performance of fluidized bed heat exchangers is due to the interaction between particles and heat transfer surface and to the mixing effects in the viscous sublayer. in this paper, the results of experimental investigations on heat transfer for a wide range of newtonian and non-newtonian (shear-thinning power law) fluids are presented. new design equations have been developed for ...

By using the newtonian gauge, we re-confirm that, as in the minimal case, the re-scaled Mukhanov-Sasaki variable is conserved leading to a constraint equation for the Newtonian potential. However, conversely to the minimal case, in Horndeski theories, the super-horizon Newtonian potential can potentially grow to very large values after inflation exit. If that happens, inflationary predictabilit...

Both for the background world model and its linear perturbations Newtonian cosmology coincides with the zero-pressure limits of relativistic cosmology. However, such successes in Newtonian cosmology are not purely based on Newton’s gravity, but are rather guided ones by previously known results in Einstein’s theory. The action-at-a-distance nature of Newton’s gravity requires further verificati...
