Conducting polymer coated in textiles possesses a wide range of electrical *** surface resistivity is influenced by concentrations of the reactants,thickness of the coating,nature of the substrate surface,extent of penetration of the polymer into the textile structure and the strength of the binding of the coating to the textile *** resistivity in fabric results from highly doped thicker coatings that penetrate well into the textile structure thus enabling good electrical contact between *** this study,we had chosen copper as conductor polymer for *** electrical conductivity is influenced by the thickness of coating paste,the nature of the substrate *** thickness of the paste and the concentration of the copper were studied in this ***,the electrical surface resistance decreased from 68 MΩto 8 MΩwith decreasing in coating ***,the thickness of coated fabric is very important factor to determine conductivity and application of *** addition,we had noticed that the airflow is affected by the coating thickness which the penetration of the airflow differs from the lower thickness to the higher *** study confirms that we can use coating woven fabric to develop a textile substrate responding to characteristics such as electrical resistance,drapability,air permeability and tensile strength,which are particularly important to be used as a support for flexible PV(photovoltaic)cells in clothes.

The need to accurately interpret geological models that approximate mineralized zones in a Basement Complex terrain necessitate the development of horizon loop electromagnetic method(HLEM)forward modeling solutions for such *** focus of the present work is on finding rapid forward modeling solutions for synthetic HLEM data as an aid in exploration for moderate to deep conductive mineral exploration *** main thrust is obtaining idealized HLEM models that are required for geological interpretation of the subsurface in such *** original HLEM equations developed by Wesley were extended to represent a horizontally stratified earth with a conductive approximated by shear *** these equations a computer program was written to calculate the HLEM responses for optimal conductor model with known values of coil separations(L),depth of burial(z)and angle of dip of the *** thin conductive model was used because it is simple and suitable for different geological *** accuracy of the approximate forward solution has been confirmed for HLEM systems with various geometric ranges,frequencies and *** models having varying overburden thickness,dip angle of target and source-receiver separation were used in the forward *** effect of varying the dip angle,overburden thickness and coil separation was studied in all the three models *** result obtained from the forward modeling showed that variation of the dip angle gave rise to changes in the amplitudes of the anomalies generated,while that of overburden and coil separation gave rise to changes in anomaly ***,the geometry and position of the causative body were precisely delineated.

Characterization of the Sulfide Deposits in the Southeastern Nigeria Using VLF Method: Insights from Numerical Modeling and Field Examples

Journal of Geological Research 2021年第1期3卷 39-49页

作者： D.E.Falebita O.Afolabi B.O Soyinka A.A.Adepelumi Department of Geology Obafemi Awolowo UniversityIle-IfeNigeria Terracon SeattleWashington DCUSA

A priori geologic and geophysical information has been used to construct conceptual VLF experiments on conductively and inductively coupled overburden geological models of the lead-zinc(Pb-Zn)mineralization zone found in southeastern *** is based on the finite element approach to(1)simulate different geologic situations of overburden occurrence,(2)examine the roles played by overburden in modifying and masking VLF responses of a buried conductor target,and(3)confirm the effectiveness of VLF method in mapping lead-zinc lodes found in sedimentary *** computed theoretical model curves and field examples are expected to serve as guide for VLF anomaly pattern recognition due to overburden thickness,resistivity and width of conductor in similar terrain as the study area.
