Field Effects

We report experimental results on microwave second harmonic emission in different superconductors in the critical state, exposed to intense pulsed mw magnetic fields. We show that the second order response of some superconducting samples shows a magnetic hysteretic behavior. We suggest that this behavior is related to non-equilibrium phenomena induced by the mw pulses. In particular, it may be ascribed to the different time response of the fluxons in the reverse and direct critical state.

Sugar cane bagasse is a common byproduct of the aZaohoZ and sugar industries. In the present work, we describe the preparation of elastomeric agglomerates containing SBR [poly(styrene-butadiene)] and bagasse or kaolin as inert filler. The experimental results and a series of laboratory and field tests show that the sugar cane bagasse agglomerate can be very appropriate and useful for practical applications, especially in the manufacture of shoe soles.

The University

The paper presents results of both tests and analysis of polyethylene pipes installed using horizontal directional drilling (HDD). A total of seven full-scale HDD field installations were performed at the University of Waterloo. The test parameters were pull length, overcut ratio, quality of the drilling fluid, pipe diameter, and pipe material. The paper presents an overview of the testing methodology, instrumentation, and test specimens. The method for measuring strains along the length of the pipe is presented and discussed. Experimental results concentrate on pipe strains due to bending and axial deformations during HDD. Post-installation axial strains are also presented. A predictive model has been developed to analyze the pipe under various installation conditions. The model accounts for major mechanical contributions to the pulling force in HDD installations. The emphasis in this paper is on the comparison between theoretical and experimental results and the discussion of factors influencing pulling loads and strains in polyethylene pipes installed using HDD.Key words: horizontal directional drilling, polyethylene, pipe, analysis, tests, strain, pulling loads.

Tank Design

Ribbed cylindrical Glass Reinforced Plastic (GRP) tanks are currently designed using simplified theory the results of which are then verified by extensive destructive testing. This approach is expensive and can only generate non-optimal design solutions. In addition, there is often a high degree of discrepancy between theoretical and experimental results which necessitates the use of undesirably high factors of safety, which in turn results in the excessive use of material with the concomitant increase in cost, weight and manufacturing time. The primary aim of this investigative research was to develop a more deterministic and accurate design method of predicting the structural integrity and performance of underground cylindrical GRP tanks using non-destructive testing. Linear and non-linear Finite Element Analysis (FEA) techniques, validated against experimental results, were used to analyze a large number of underground ribbed cylindrical GRP tanks. The outcome of which was then expressed in the form of an empirical ‘Design Formula’ which provides a comprehensive solution to ribbed cylindrical GRP tank design for a wide range of tank sizes, laminate lay-ups and material properties. It is intended that the application of this method will eliminate the need for the expensive field tests that are currently required by design codes and standards.

Crude Estimate

In such highly resistive geologic environments as ice sheets, salt layers, and the moon’s surface, radio waves penetrate with little attenuation. The field strengths about a transmitting antenna placed on the surface of such an environment exhibit interference maxima and minima which are indicative of the in‐situ electrical properties and the presence of subsurface layering. Experimental results from an analog scale model and from field tests on two glaciers are interpreted on the basis of the theoretical results of Part I. If the upper layer is thick, the pattern is very simple and the dielectric constant of the layer can be easily determined. An upper bound on the loss tangent can be estimated. For thin layers, the depth can be determined if the loss tangent is less than about 0.10, and a crude estimate of scattering can be made.
