چکیده
• We present an innovative approach for non-invasive quantification of the water content in unsaturated limestone. confirm possibility time-lapse MRS measurements content. In our test site, shows seasonal and annual variations zone. use existing hardware software that renders method easily available users. hydrogeophysical flow. For measurements, we apply Magnetic Resonance Sounding (MRS) mode. inversion approximate subsurface by a horizontally stratified media. Laterally, estimated is averaged over area below measuring setup. During this study, used square loop 75 m side-length. The allows visualizing vadose zone down to twenty meters. tested at Villamblain site (France). that, carried out monitoring 1999–2000 2020–2021. these two observation windows, but also strong dependence on rainfall was different between data sets. Comparison results with records good correspondence in-between. processing data, commercially instrument interpretation software.

Monitoring tissue engineering using magnetic resonance imaging.
Assessment of tissue regeneration is essential to optimize the stages of tissue engineering (cell proliferation, tissue development and implantation). Optical and X-ray imaging have been used in tissue engineering to provide useful information, but each has limitations: for example, poor depth penetration and radiation damage. Magnetic resonance imaging (MRI) largely overcomes these restriction...
متن کاملGroundwater recharge simulation using a coupled saturated-unsaturated flow model
Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...

An integrated surface geophysical pilot study at the Texas A&M University Brazos River Hydrologic Field Research Site (BRHFRS), College Station, Texas, was done to determine the effectiveness of methods for defining the hydrostratigraphic framework and hydrogeologic properties for a ground-water availability model. Time-domain electromagnetic (TDEM) soundings and direct-current (2D–DC) resistiv...
