ELIMINATION OF CRUPTOLESTES FERRUNGINEUS S. IN WHEAT BY RADIO FREQUENCY DIELECTRIC HEATING AT DIFFERENT MOISTURE CONTENTS

Radio-frequency Density-independent Moisture Determination in Wheat

A technique to rapidly determine the moisture content of hard red winter wheat, Triticum aestivum L., independent of densityy is presented. The complex impedance of bulk samples at 1 and 10 MHz was used along with a density-independent function to predict moistures ranging from approximately 11 to 22% in samples with bulk densities ranging from 0.65 to 0.85 glcm^. Calibration was performed on w...

Variation of Dielectric and Attenuation Properties for Tree Leaves with Moisture Contents at Microwave Frequency

Present studies report the experimental results on the dielectric and attenuation parameters for leaves of two different tree species at X-Band microwave frequency, 10.5 GHz. Leaves of two different tree species viz., Azadirachta indica (Neem) and Acacia indica (Babool) have been used in these measurements. Complex dielectric constants of these tree leaves have been measured by using waveguide ...

Estimation of Moisture in Transformer Insulation Using Dielectric Frequency Response Analysis by Heuristic Algorithms

Transformers are one of the most valuable assets of power systems. Maintenance and condition assessment of transformers has become one of the concerns of researchers due to huge number of transformers has been approached to the end of their lifetimes. Transformer’s lifetime depends on the life of its insulation and the insulation’s life is strongly influenced by its moisture attraction as well....

The Viability of Oil Extraction from Trinidad Tar Sands by Radio Frequency Heating: A Simulation Approach

Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...
