Ground Penetrating Radar (GPR) is an effective and practical geophysical imaging tool, with a wide set of applications in geological mapping of subsurface information. This research study aims at determination of the geophysical parameter differences in the subsurface geological structures and construction of a 3D fracture model. GPR and resistivity methods were applied to detect the unstable t...

Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method that can quickly and accurately locate buried archaeological features, artifacts, and important cultural strata in the near-surface. The GPR method has been especially effective in certain sediments and soils between about 20 cm and 5 m below the ground surface, where the targets to ...

Considerable research has focused on issues pertaining to sensorimotor integration, but in most systems precise information remains unavailable regarding the specific pathways by which different sensory systems regulate any single central pattern-generating circuit. We address this issue by determining how two muscle stretch-sensitive neurons, the gastropyloric receptor neurons (GPRs), influenc...

MendeUan Inheritance: Co-dominant inheritance was observed in a five-generation pedigree in which 113 individuals were typed. Other Comments: The PCR was performed using P-labeled GPR 112-1 and unlabeled GPR 112-2 for 30 cycles: denaturation at 94°C for 1 min; annealing for 55°C for 1.5 min; and extension at 72°C for 3 min. The PCR products were analyzed on a 5% denaturing polyacrylamide gel (F...

In this work we consider the problem of determining the dielectric characteristics of sub-surface layers by means of GPR systems. In particular, a suitable electromagnetic feature (the R0 parameter), strictly related to the geophysical parameters of the scenario, is first extracted from the GPR e.m. signal and then fed to an artificial neural network (ANN) in order to derive the dielectric perm...

Pavement damage is actually one of the most crucial problems in roads. Agencies need first to localize the damage, second to identify the causes. Indeed, the rehabilitation can be compromised, if the cause is not removed. The ground penetrating radar (GPR) technique is used by many agencies involved in roads management. In fact, it is nondestructive and is promising for soil characteristics int...

INTRODUCTION The aim of this work is to verify the use of radiochromic film in the quality assurance (QA) of volumetric-modulated arc therapy (VMAT) lung stereotactic body radiation therapy (SBRT) plans and compare the results with those obtained using an ion chamber array. MATERIALS AND METHODS QA was performed for 14 plans using a two-dimensional-array seven29 and EBT3 film. Dose values per...

An integrated geophysical survey using both the electrical resistivity tomography (ERT) and groundpenetrating radar (GPR) methods was undertaken over a cave of great archaeological interest in southern Italy. The survey was performed to assess the stability of the carbonate rock roof of the cave. A geophysical survey was preferred to boreholes and geotechnical tests, in order to avoid the risk ...

Methods for determining the parameters necessary for modeling fluid flow and contaminant transport in the shallow subsurface are in great demand. Soil properties such as permeability, porosity, and water retention are typically estimated through the inversion of hydrological data (e.g., measurements of capillary pressure and water saturation). However, ill-posedness and non-uniqueness commonly ...

Ž . Field experiments show ground penetrating radar GPR can be used to image shallow carbonate stratigraphy effectively in a variety of settings. In south Florida, the position and structure of cap rock cover on limestone can be an important Ž . control on surface water flow and vegetation, but larger scale outcrops tens of meters of cap rock are sparse. GPR mapping through south Florida prairi...
