Abstract: A soil probe assembly includes a frame member and a wheel rotatably coupled to the frame member. The wheel includes one or more soil probes that, as the wheel rotates against the earth, the weight of the soil probe assembly drives the soil probes into the earth. The wheel is configured to have at least two planar edges such that, as the wheel rolls onto one of the at least two planar edges, a slamming effect occurs due to the planar edge impacting against the ground, thus causing a soil sample to eject from a soil probe located across the wheel from the ground. The ejected soil sample is collected by a collection hamper. The assembly includes a funnel and a carousel such that the funnel is configured to receive and direct the ejected soil sample to the collection hamper, wherein the collection hamper is coupled to the carousel.

Abstract: An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

Abstract: A multifunctional and modular geotechnical testing device for testing a soil sample is provided. The testing device includes a testing cell, a plurality of needle probes, and a plurality of lateral pressure-measuring sensors. The testing cell has an oedometer ring for accommodating the soil sample, with a plurality of holes located on and angularly distributed over an internal lateral surface of the oedometer ring forming a plurality of channels to access the soil sample from outside. The plurality of needle probes, each configured to house a pore water pressure-measuring sensor, is detachably mountable to the plurality of channels from outside for simultaneously measuring the pore water pressures. The plurality of lateral pressure-measuring sensors is removably attachable to an inner peripheral side of the testing cell for measuring lateral pressures of the soil sample.

Abstract: A sample confinement tool includes a first end and a second end. The first end of the sample confinement tool is coupled to a driving tool. The driving tool is coupled to a heavy-duty vehicle. The sample confinement tool is operable to insert a predetermined depth below a ballast surface and collect a ballast sample within the second end of the sample confinement tool. The sample confinement tool is also operable to confine the ballast sample within the second end of the sample confinement tool by mechanically compressing the ballast sample. The sample confinement tool is further operable to release the ballast sample into a sample receptacle by mechanically decompressing the ballast sample.

Abstract: A method for collection of dry samples taken directly from a nuclear reactor core interior. Incremental samples of irradiated metal alloy components of the reactor core may be taken and collected in-situ using a specialized metal-cutting drill bit having a hollow tungsten carbide sampling cutting head, in conjunction with an angled sampling gantry. The drill bit body has an interior airflow passage in hermetic communication with a filter located in a glove box. Air holes are formed through a face of the cutting head. A vacuumed airflow through the airflow passage and at the cutting head causes a sample of any of metal chips, filings, and dust to be obtained directly from the reactor core by being pulled through the air holes and into the airflow passage and ultimately into the filter. A collected sample may be analyzed for radionuclides and radioactivity level.

Abstract: The present disclosure is directed to implementations of systems and methods for plant tissue sampling utilizing a sampling clip. The clip may be used to obtain a tissue sample of a plant and retain the sample for subsequent analysis. The clip, including the sample, may be shipped (if necessary) without the user ever needing to contact the sample directly. In many implementations, the sample may be automatically extracted from the clip for analysis without requiring human intervention. As a result, cross-contamination possibilities may be avoided or eliminated. The clip and/or sample collectors may be disposed of after use or sterilized in a group.

Abstract: Techniques for determining the suitability of a subterranean formation as a hazardous waste repository include determining a neutron flux of a first isotope in a subterranean formation; calculating, based at least in part on the determined neutron flux of the first isotope, a predicted production rate of a second isotope in the subterranean formation; calculating a first ratio of the predicted production rate of the second isotope relative to a theoretical production rate of a stable form of the second isotope; measuring respective concentrations of the second isotope and the stable form of the second isotope in a subterranean water sample; calculating a second ratio of the measured concentration of the second isotope relative to the measured concentration of the stable form of the second isotope; and based on a comparison of the first and second ratios, determining that the subterranean formation is suitable as a hazardous waste repository.
