Electromagnetic wave scattering by many parallel infinite cylinders is studied asymptotically as a → 0. Here a is the radius of the cylinders. It is assumed that the points x̂m are distributed so that N (∆) = 1 a R ∆ N(x)dx[1+o(1)], whereN (∆) is the number of points x̂m = (xm1, xm2) in an arbitrary open subset of the plane xoy, the axes of the cylinders are passing through points x̂m, these axes ...

: This paper gives a comprehensive overview and understanding related with mixed convection in cylinders. About onehundred papers which are published in different local and international journals and conferences started from the past decade until the recent years are collected and described in various sections to give both researchers and readers a good overview and a solid background about mix...

Most patients with chronic obstructive lung disease prescribed oxygen at home by their family doctor use it for short periods when they feel breathless. Many patients are normoxic. Nineteen patients with advanced disease and variable hypoxaemia undertook exercise until they indicated severe breathlessness on a 100 mm visual analogue scale. Air, 67% oxygen, and air delivered from a cylinder in a...

cylinders utilising elastic materials of cylindrical anisotropy. The formulation is based on linear three dimensional elasticity using an analytic form for the displacement field. A similar formulation has been used in the study of waves in plates and more recently, by the authors, in homogeneous cylinders. We have now developed the necessary formulas to apply it to cylinders in which the inhom...

We define and study the Magnus representation for homology cylinders generalizing the work of Kirk, Livingston and Wang [KLW] which treats the case of string links. Using this, we give a factorization formula of Alexander polynomials for three dimensional manifolds obtained by closing homology cylinders. We also show a relationship between the Gassner representation for string links and the Mag...

The Institute for Certified Reference Materials (ICRM) issued the first time certified reference materials (CRM 11777-2021) of mass fraction hydrogen, oxygen and nitrogen in titanium-based materials, i.e., titanium alloy 2V (ISO 1-1) VT 1-00 1-2). finished material is presented form cylinders 2.5 mm diameter 5-6 height. a cylinder about 0.1 g. To certify gas-forming elements, we used methods fu...

We investigate the structure of polystyrene-b-poly(acrylic acid, sodium salt) copolymer in aqueous solutions. We offer detailed characterization of the micellar solutions by scattering techniques and show that they form hexagonal-packed cylinders. The micelles follow the swelling law expected for cylinders, upon addition of water, down to a concentration threshold below which the distance cylin...

In this study, thermo elastic stress analysis is performed on a cylinder made of laminated isotropic materials under thermomechanical loads. Laminated cylinders have many applications such as aerospace, automotive and nuclear plant in the industry. These cylinders generally performed under thermomechanical loads. Stress and displacement distribution of the laminated cylinders are determined usi...

The deterioration of bond strength between reinforcing steel and concrete as a result of impressed cathodic current with respect to the exposure time was investigated. A current in the magnitude of 3ma/ft2 (based on reinforcing rebar area) was used for a period of five years. Chemical analyses for sodium (Na+), potassium (K+) and chloride (Cl-) ions in concrete cylinders were performed as a fun...

In this paper, the reconstruction mechanism of the boundary layer in the channel is studied using the lattice Boltzmann method (LBM). By comparing the distribution of velocity in the channel, the conclusion that LBM has feasibility and superiority is obtained. Based on this, a physical model of square cylinders is set up to simulate the velocity distribution and the effect on the thickness of b...
