Pertamina has conducted geothermal exploration in Sumatra showing that the depths to the top of most of the geothermal reservoirs are about 1000-2000 meters. Previous geophysical exploration work by Pertamina emphasized the use of DC-resistivity methods such as the Schlumberger method. However, these techmques can typically only penetrate to a depth of less than 1000 meters and are too shallow ...

Characterization of material changes with depth (profiles) in many landfill sites can be problematic for some conventional geophysical methods. Localized anomalies within the landfill can complicate mapping of underlying layers, and layered-model techniques are inappropriate for imaging laterally discontinuous landfills. Recently-developed geophysical hardware and software tools provide the opp...

Since the last few decades, electrical methods have been widely used in geophysical surveying to obtain high-resolution information about subsurface conditions. Resistivity is an important parameter in judging the ground properties, especially detecting buried objects of anomalous conductivity. Electrical DC resistivity sounding is the commonly used technique to obtain the apparent 2-D resistiv...

The calculation of apparent resistivities, based on the model of a homogeneous half-space, is commonly the first step in Ž . order to evaluate helicopter electromagnetic HEM data. Due to the increase in frequencies used in HEM systems, survey results are not only displayed as apparent resistivity maps but also as cross-sections that require resistivity and depth information. After a brief descr...

In the United States, nursing programs are commonly evaluated by their graduates success on the National Council Licensure Examination for Registered Nurses (NCLEX-RN c ©). The purpose of this paper is to describe a change in NCLEX-RN c © success rates following the addition of standardized exams throughout our program’s curriculum, and to compare these exam scores between graduates who pass NC...
