Experimental studies have shown that the axial and azimuthal turbulence intensities in the gap regions of rod bundles increase strongly with decreasing rod spacing; the fluctuating velocities in the axial and azimuthal directions have a quasi-periodic beh...

This is a study about dose distribution in the larynx region under irradiation with a 10 MV photon beam. This localization presents air cavities, that can compromise the dose at air-tissue interfaces by electronic equilibrium loss and backscattering lack....
The results obtained from the development PVC dose indicator films, from the PE and PP hydrophilization and from the formulations of crosslink able resins and curable inks and varnishes by radiation, are herein discussed. (author). (Atomindex citation 24:...
In this work a different system is proposed which is able to verify the absorbed depth dose given at two different depths, the irradiation field homogeneity and its coincidence with the light field of the machine, the source to surface distance used and t...
Samples of drinking water and waste water were irradiated using high energy electron beam with doses from 0.37kGy to 100kGy. Preliminary data show the removal of about 100% tri halomethanes (THM) in drinking water concentration from 2.7 (mu)g/1 to 45(mu)g...
For each positive integer n, let Fn be a free group of rank n with basis (in other words, free generating set) {x1, �, xEM>n>} . If [theta] is an automorphism of <EM>Fn> then {<EM>x>1[theta], �, ...

It is a classical result of Postnikov [15] that homotopy types X with at most two non-trivial homotopy groups [pi]mX = A and [pi]n<EM>X> = <EM>B>, 2 [less-than-or-eq, slant] <EM>m> < <EM>n>, are classified by the ...
The Multiple Application Intense Particle Beam project is an experiment in which an injector of high energy neutral or ionized particles will be used to diagnose high density and high temperature plasmas. The acceleration of the particles will be carried ...
The theory of reductive monoids has been well developed by Renner and the author, cf. [8, 13]. This paper concerns the finite reductive monoids MF where M is a reductive monoid and F[ratio]MEM>[rightward arrow]<EM>M> is a Frobenius map. We show that the Deligne-Lusztig characters ...
We compute the (uni)versal deformation ring of an odd Galois representation [rho]: Gal (M/Q) [rightward arrow] Gl2(Fp) with an upper triangular image, where MEM> is the maximal abelian pro-<EM>p>-extension of <EM>F>[infty infinity] unramified outside a finite set of places ...

The low-Reynolds-number collision and rebound of two rigid spheres moving in an ideal isothermal gas is studied in the lubrication limit. The spheres are non-Brownian in nature with radii much larger than the mean-free path of the molecules. The nature of the flow in the gap between the particles depends on the relative magnitudes of the minimum gap thickness, h[prime prime or minute]o, the ...
Stably stratified flows past three-dimensional orography have been investigated using a stratified towing tank. Flows past idealized axisymmetric orography in which the Froude number, Fh=U/Nh (where U is the towing speed, N is the buoyancy frequency and hEM> is the height of the obstacle) is less than unity have been studied. The orography considered consists of two ...
We show that the sequence 2n+n is a universal Hilbert sequence. That is, for each polynomial P(T, Y) irreducible in [open face Q](T) [YEM>], the polynomial <EM>P>(2<EM>n+n>, <EM>Y>) is irreducible in [open face ...
For E a subset of [open face R]n and s [set membership] [0, n] we define upper and lower box dimension profiles, B-dims<EM>E> and B-dim<EM>sE> respectively, that are closely related to the box dimensions of the orthogonal projections of <EM>E> onto ...
Let M be a compact, orientable 3-manifold with [partial partial differential]M a torus. If r is a slope on [partial partial differential]M (the isotopy class of an unoriented essential simple loop), then we can form the closed 3-manifold M(r) by gluing a solid torus V<EM>r> to <EM>M> along their boundaries in such a way that ...
