Cyclic and Impact Resistance of FRP Repaired Poles
… damage are substantial. The replacement of these poles is costly and involves interruption for pedestrians and traffic. Therefore, some trials were performed to retrofit these poles in-situ with low cost and short time. Previous research has substantiated that the damage can decrease the strength …

Ultrasonic-Based Condition Assessment of Wooden Utility Poles
<p>More than 300 million utility poles shoulder the utility grid in the United States. However, the ineffectiveness of the current inspection process causes roughly a third of utility poles removed from the service deemed suitable for reuse. Due to the utterly essential role of the power …

Father Anastasius Czech and the Poles of Nebraska
To write the history of the Polish settlements of Nebraska with a view to showing how a group of Europeans with all their foreign characteristics, through honest effort moved by the spirit of heroic courage to brave the hardships of pioneer life, joined with mutual co-operation and charity, have …

Identification and Explanation of Regional Development Poles in Haiti
… of primate cities by focusing on development poles. In Haiti, the potential growth poles are the regional capitals that have a constitutional mandate to promote and manage the development of their region. I have tested some of the assumptions of dependency and growth pole theories on Haiti, …

Biological control of internal decay in creosoted distribution poles
… as a primary decay fungus in creosoted poles from the literature and from studies of poles in Scotland) was overgrown and lysed or lysed from a distance by all control fungi when grown on the same agar plates. Other organisms resident in poles produced either a similar result or produced …

Rot detection in wooden poles using electrical impedance tomography
… nondestructive method of testing wooden utility poles for rot and termite damage. The nondestructive method that was chosen for this project was that of electrical impedance tomography in which an image of the permittivity in a cross section would be created from impedance measurements made …

Suitability of Casuarina equisetifolia as utility poles in Senegal
… trees grown in Senegal as utility poles was investigated as follows: (1) to determine the longitudinal air permeability of the species with regard to its treatability; (2) to determine the treatability of the wood using a full-cell process; (3) to determine the mechanical properties …

The Loss in Solid Poles of Synchronous Machines On Load
The loss in solid poles of synchronous machines on load may be caused by several travelling waves and the thesis is directed towards a discussion of the problems arising from the superposition of these waves and of the effect of the superposed main field, which is stationary relative to the poles. …

The in-service non-destructive evaluation of wooden transmission line poles
… Evaluation of Wooden Transmission Line Poles. The aim of this work was the development of an effective pole tester that could be used to test the integrity of wooden transmission line poles in situ. The pole testing method that ESKOM uses at present is both time and labour intensive and …

High resolution modal analysis using poles obtained at a single location
A method, termed the fixed-poles method, is proposed to increase the spatial resolution of experimental modal analysis results so that the resolution of the results is typical of that found in finite element modelling. The fixed-poles procedure estimates the structure’s poles from a high frequency …

A study on the behaviour of guided wave propagation in utility timber poles
… The round timber is suitable for electricity poles, wharfs, piles, bridge piers, etc. There are nearly 7 million utility poles in the current network in Australia, in which around 5 million timber poles are used for distribution of power and communications. The utility pole industry in …

Use of biological agents to enhance the preservative treatment of electrical distribution poles
Treatment of timber with preservative varies from species to species. Poor preservative penetration has been associated with wood decay and shortened service life of treated timbers. The preservation of Sitka spruce and Scots pine heartwood by conventional methods is poor with the depth of …

Design of a lightweight camping cot using carbon fiber tent poles and ripstop nylon
… The lightweight cot utilizes carbon fiber poles for its structural support and ripstop nylon for the cot surface. The carbon fiber poles are connected with plastic fittings. Each of the cot's components was selected due to its highly lightweight properties and overall strength.
