Assessment of Tonsil-Oral-Scrubbing (TOSc) to detect PRRSV RNA in sows and application of TOSc for PRRSV dynamics in breeding herds
… rope (Pepin et al., 2014). A novel Tonsil-Oral-Scrubbing (TOSc) sampling method was recently developed, which retrieve fluids within seconds from the sow’s oral and tonsillar area without the necessity of snaring (Li et al., 2024). That study reported PRRSV RNA detection rate in TOSc samples …

Feasibility of an integrated biogas scrubber for a swine manure digester
Laboratory experiments were conducted to study a scrubbing system for the removal of carbon dioxide (CO$\sb2$) from the biogas produced by a swine manure anaerobic digester. This innovative scrubbing system was included in the original design of an existing full-scale digester, but had never been …

Emissions testing of two recreational marine engines with water contact in the exhaust stream
… tested with exhaust gas/cooling water mixing (scrubbing) in the exhaust stream using both freshwater and saltwater. Additionally, the inboard engine was tested without exhaust scrubbing. Gaseous emissions (HC, NOx, CO, and CO2) from the engines were continuously measured using a constant volume …

Mitigating material supply risks: evaluation of abrasion specific comminution for commercial recovery of indium from waste liquid crystal displays
… approach of removing coatings known as attrition scrubbing was selected as a promising approach for further study due to the ability to upgrade indium by a factor of >10 at >90% recovery in less than 10 minutes at low cost. A business case evaluation of optimal processing plant size was used to …

Simulations and modeling of biomass gasification processes
… test conditions for the solids removal and scrubbing (condensation) systems. The model as it is currently formulated is not capable of predicting gasification output mixture compositions. It is desirable to decrease the amount of carbon dioxide and tars (defined for this study as compounds …

In-System Testing of Configurable Logic Blocks in Xilinx 7-Series FPGAs
FPGA fault recovery techniques, such as bitstream scrubbing, are only limited to detecting and correcting soft errors that corrupt the configuration memory. Scrubbing and related techniques cannot detect permanent faults within the FPGA fabric, such as short circuits and open circuits in FPGA …

High-level synthesis of triple modular redundant FPGA circuits with energy efficient error recovery mechanisms
… Triple Modular Redundancy (TMR) with periodic CM scrubbing or Module-based CM error recovery (MER) are popular techniques for mitigating soft errors in FPGA circuits. However, this thesis shows that MER does not recover CM soft errors in logic instantiated outside the reconfigurable regions of TMR …

Transient Error Recovery Techniques for Pipelines and Memory Systems
… of system recovery from transient errors. Scrubbing methods are suggested for memory systems and retry techniques are discussed for pipelines. A probabilistic model for the activity of faulty periods is introduced, and a fault analysis is carried out to decide the optimum length of the …

Electrochemically-mediated amine regeneration for carbon dioxide separations
… in a similar manner to standard thermal scrubbing techniques. The desorption of the CO₂ from the loaded amines is achieved through the oxidation of a copper metal anode, which generates cupric ions that compete for the amine binding sites. For many amines, the complexation with cupric …
