Determination of entrapment victim extrication forces with and without use of a grain rescue tube
Citation: Roberts, M. J., Field, W. E., Maier, D. E., & Stroshine, R. L. (2015). Determination of entrapment victim extrication forces with and without use of a grain rescue tube. Journal of Agricultural Safety and Health, 21(2), 71-83. doi:10.13031/jash.21.10150The forces required to extricate a test mannequin from a grain mass when buried at different depths with and without a grain restraint system were determined. When there was no grain restraint system in place, the vertical force required to pull the mannequin from the grain when it was buried waist deep and to the underarms was 1259 and 1766 N (283 and 397 lbf), respectively. It increased to 1584 N (356 lbf) (+26%) and 2153 N (484 lbf) (+22%), respectively, with the restraint in place due to the changes in grain properties brought about by the insertion of the rescue tube. It was concluded that the use of a grain restraint during extrication of a victim does not reduce the forces required and that forcefully pulling an entrapped victim, especially with mechanical assistance, with or without a grain restraint system could result in severe injuries and possible death due to the forces exerted on the victim. The authors recommend that these findings be incorporated into current grain extrication training for emergency first responders. © 2015 ASABE

Prototype of non-destructive fruit sweetness sensor
A model LL-4 magnetic resonance low level unit designed to operate at 5.35 MHz was used to perform proton magnetic resonance ({sup 1}H-MR) tests on sugar solutions. The magnet console was designed and built by Agricultural Engineering Department personnel. The homogeneity of the magnetic field is critical to achievement of a good signal and to good performance of the device. Measurements of magnetic field strength along the major axes of the air gap are reported. Test tubes were filled with sugar solutions and placed in the air gap between the permanent magnets in the magnet console. Sugar solutions containing 0% to 30% sucrose were interrogated using, the Hahn spin echo pulse sequence. The amplitude of the echo peak was well correlated with percent sugar content in solutions
