We report measurements of the energy dependence of the total neutron scattering cross-section of CH4 both in bulk and confined in aerogel glass for neutron energies between 0:3 and 200 meV. Solid CH4 in phase II is an effective slow neutron moderat...

From the frontier of this paper, unless specified something else, let it be agreed that all groups into consideration are p-primary abelian for some arbitrary but fixed prime p written additively as is the custom when dealing with abelian group theory. The present short note is a contribution to a recent flurry of our results in [6]. Standardly, all notions and notations are essentially the sam...

For the past several years, there has been a lot of work in modelling complex simulations pertaining to motion of gases. In the work of [Fedkiw et al., 2001], a new approach to numerically simulate smoke was developed which incorporates the model proposed by Steinhoff and Underhill [Steinhoff and Underhill, 1994] known as “vorticity confinement”. Passive advection of smoke particles is consider...

proton transfer (pt) and methyl group transfer (mgt) occurring in small biomimetic systems, formamide-formamidic acid (fa-fi), and n-formyl-n-methylformamide-(e)-methyl n-formylformimidate (nmfa-nmfi) are investigated in the gas phase and in single-walled carbon nanotubes by using the density functional theory and the oniom approach. it is shown that pt reaction is disfavoured in single-walled ...

A study was conducted to compare growth performance and behaviors of group-farrowed pigs with those of confinement-farrowed pigs. A total of 216 pigs (8 wk of age) were used, with an equal number of group-farrowed or confinement-farrowed pigs from 1 farrowing batch. Group-farrowed pigs were farrowed in bedded, individual pens and mingled into a group of 8 litters at 12 (±1.3) d of age. Pigs wer...

reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. a unified theory for confinement of circular hollow sections is proposed herein, that can be extended to the case of solid and noncircular sections. the main aim of the model is to trace step-by-step the evolution of ...

A brief and biased overview of the phenomenon of confinement in QCD is presented in three parts: (1) the definition of confinement, (2) properties of confinement, (3) ideas of confinement. The second part chiefly consists of a brief review of recent lattice computations related to confinement while the third summarizes some of the current analytical approaches to understanding confinement. Thes...

In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, three-dimensional hybrid guided modes can be calculated by us...

An experimental study of the effect of silt and influence of cell confinement on the bearing capacity of circular footings on silty sand was carried out. Laboratory experiments on clean sand and sand containing silt up to 25 % were performed. Cells with different heights and diameters were used to confine the silty sand. The effect of proportion of silt in sand, cell diameter, cell height and t...
