A soil-based measure of evapotranspiration
… to implement this procedure are tensiometers, a neutron probe (or some other means of quantifying the moisture content at depth in a non-destructive manner) and a hand-operated gravimetric sampler. This method was found to perform satisfactorily for periods as short as 6 days. An extensive error …

14 MeV neutron generator dose modeling
Modeling and understanding the doses around the neutron generator provides insightful data in regard to radiation safety and protection precautions. Published data can be used to predict doses, but realistic data for the Nuclear Engineering Teaching Laboratory’s Thermo MP 320 Neutron Generator …

Thorium-based mixed oxide fuel in a pressurized water reactor: A feasibility analysis with MCNP
… performed for the Portable Spectroscopic Fast Neutron Probe (N-Probe), which can be used for spent fuel interrogation. Also, a Canberra <sup>3</sup>He neutron detector's dead-time was estimated using a combination of subcritical assembly measurements and MCNP simulations. Next, a multitude of …

Tillage effects on soil-water-air matrix and prediction of soil bulk density from cone index data
… by soil type and moisture conditions. The neutron probe densitometer is difficult to use in tillage studies due to practical problems. Among the predictive models for bulk density, some require parameters determined through expensive laboratory procedures while others have not been proven …

Characterisation of sedimentary structure and hydraulic behaviour within the unsaturated zone of the Triassic Sherwood Sandstone aquifer in North East England
… Moisture content has also been monitored using a neutron probe, and a commercially-available portable packer system, which have provided verification of the accuracy of the custom-made TDR system. The TDR installations consisted of automated arrays of TDR probes, permanently installed upon …

Effect of sinkholes on soil moisture and ground water recharge at an abandoned underground coal mine near Wilton, North Dakota
… sinkholes and five non-collapsed settings with a neutron probe. Tensiometers were installed to establish the direction of hydraulic gradients in the shallow unsaturated zone. Climatic data were obtained from the National Weather Service station in Wilton. </p><p>Soil moisture conditions were …

Genotypic variation in water use efficiency, gaseous exchange and yield of four cassava landraces grown under rainfed conditions in South Africa
… interval from sowing until harvest using a neutron probe. Soil moisture data were used to determine crop water use using the water balance approach. There was no variation in the root yield and yield components amongst the landraces in 2017/2018 cropping season but, genotypes affected …
