The electronic paramagnetic resonance (EPR) technique was utilized to study sand samples from different Brazilian beaches for high-dose dosimetry. Sand also contains concentrations of heavy minerals. Sand samples were studied in relation to their main dosimetric properties: response reproducibility, reutilization, batch uniformity, detection range and dose response. The EPR signal grows significantly as a function of absorbed dose for g=1.999g=1.999. All studied sand samples can be used as EPR dosimeters for different applications in medical, agricultural and industrial areas.
A new field single wheel testing device, as part of a field testing unit, was developed to perform traction tests on agricultural or cross country tires in the field. The tire testing device is mounted at the rear of Discount Ugg Boots Co Uk
a heavy wheeled tractor that also carries a unique soil property testing device at the front. The vertical, horizontal Buy Ugg Boots Uk Cheap and side forces are measured inside a frame that holds the test wheel, while the torque is measured by a separate linkage system. The tire testing device is capable of testing tires up to 2 m in diameter; it can apply vertical force up to 50 kN, and torque up to 31 kNm.
