Simplified procedure to estimate the resistance parameters of transmission lines
(2013-09-01)
An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the ...
Influence of the Test Specimen Diameter on the Measurement of Electrical Resistivity in Sands by Using Laboratory Devices
(Brazilian Soc Soil Mechanics & Geotechnical Engineering, 2016-05-01)
Electrical resistivity tests have long been used in geo-environmental site characterization because they provide qualitative data to identify the presence of contaminants in soil. The measurement of soil electrical resistivity ...

Electrical resistivity measurement of unsaturated concrete samples
(ICE Publishing, 2014-04)
Electrical conduction in concrete primarily occurs via the liquid in pores. Since concrete resistivity is sensitive to moisture content, resistivity can be used to infer other moisture-dependent concrete properties. However, ...
Relationship between biogas production and variations in electric resistivity in landfill of rio Claro city, Brazil
(2015-01-01)
This work relates measures of the biogas flow in drains located on landfill with measurements of electric resistivity, obtained by the technique of geophysical logging by measuring cable installed in two vertical boreholes ...

PncA gene expression and prediction factors on pyrazinamide resistance in Mycobacterium tuberculosis
(Elsevier, 2013)
Mutations in the pyrazinamidase (PZAse) coding gene, pncA, have been considered as the main cause of pyrazinamide (PZA) resistance in Mycobacterium tuberculosis. However, recent studies suggest there is no single mechanism ...
Comparing resistance to open data performance measurement: public education in Brazil and the UK
(Wiley, 2017-03)
Much is known about governmental resistance to disclosure laws, less so about multi-stakeholder resistance to open data. This study compares open data initiatives within the primary and secondary school systems of Brazil ...
