title = "Effects of temperature compensation on electrical resistivity during subsurface characterization",
abstract = "Electrical resistivity has been used to estimate the spatial variability of subsurface soil. The objective of this study is to evaluate the effects of temperature on electrical resistivity to create more accurate subsurface characterization using a temperature-compensated resistivity probe (TRP). The TRP consists of a two-electrode electrical resistivity module and temperature sensors, which are used to monitor temperature changes and the compensation of electrical resistivity that occurs due to temperature changes. Temperature transfer probes with diameters of 5 and 10 mm are developed to measure temperature changes during the penetration of probes into sandy soils. The temperature sensors are attached 15 mm behind the probe tips to minimize electrical interference with the electrical resistance measurement component of the TRP. Laboratory application tests are conducted in an acrylic cell containing uniform Jumunjin sand, and field application tests are conducted in loose silty clay and sand in the Kimpo area near Seoul. The test results show that the temperature changes continuously during probe penetration in both the laboratory and field tests, and electrical resistivity is over- or under-estimated when temperature compensation is not considered. This study demonstrates that temperature changes should be accounted to improve the accuracy of electrical resistivity measurement and the quality of subsurface characterization.",

note = "Funding Information: At the time of the EWGT constitu tion in Maffiiers, one of the first goals of the Group Elected Board was to obtain from the European Community the inclusion of gene therapy as a specific subject for funding in the contest of European funding programs. {"}Gene Therapy in Europe{"}, has been entering a new phase in 1995 and two major achievements should be recorded: {1 ) Research Funding of European Labs. Somatic gene therapy appears as a priority in the 4th framework programmes of the DGXII both in {"}Biomed 2{"} and {"}Biotechnology{"}; this represents a significant step forward, since until now official recognition of this field of research by the European Parliament and the Commissions of the European Union was highly disputed. This is expected to positively affect gene therapy research and will foster new international collaborations. Significant funding from the Commission of the European Communities (DGXII) provides financial support at a level otherwise not accessible. Programmes supported by the DGXII favour collaboration between various European teams towards providing additional quality through so-called {"}European added value{"}. (2) Regulation. The CPMP \[Committee for Proprietary Medicinal Products) has approved (last December 1994) a final draft of the {"}Gene therapy products: quality aspects in the production of vectors and genetically modified somatic cells{"} thereby releasing guidelines for putting gene therapy products on the market s (DG III/3477/92. Ad hoc Working Party on Biotechnology/Pharmacy: Production and quality control of medicinal products derived by recombinant DNA technology, revision 1994.) z The primary purpose of this document is to provide guidance on the data required to support applications for marketing authoriza- Publisher Copyright: {\textcopyright} 2014, Springer-Verlag Berlin Heidelberg.",
