Experimental Evaluation of Three Backward Transit Time Distributions (bTTD) for Solute Storage and Release During Hyporheic Exchange
… in hyporheic zone storage are sampled for outflow: (1) uniform sampling (exponential bTTD), plug-flow sampling (Dirac delta bTTD), and preferential sampling of either young or old water (Gamma bTTD). Using the Method of Moments, these three bTTDs were tested against data from 47 previously …

Development of a semivolatile aerosol dichotomous sampler
… some of the problems of existing personal sampling methods such as evaporative loss during filter sampling. The main difference between virtual impactors and the SADS was the inverted flow ratio between the major and the minor flow. Sampling in the SADS settings gave a lower cutsize in both …

Nutrient Movement in Streamside Management Zones and Piedmont Streams Following Forest Fertilization
… surface water collectors. Near-surface water flow sampling using ionic exchange membranes resulted in our most complete dataset and showed infrequent lateral ion transport in the litter and upper soil layers even after water passed over an approximately 1m wide, seeded firebreak located …

Development of a Novel Probe for Engine Ingestion Sampling in Parallel With Initial Developments of a High-speed Particle-laden Jet
… there is a lack of literature that focuses on sampling particles directly from the flow inside an engine. Instead, experimental studies that estimate the trajectories and behavior of particles are based upon the resulting erosion of blades and the expected aerodynamics and physics of the …

Evaluation of a Particle Sampling Probe to Measure Mass Concentration in Particle-Laden Flows
… the particle mass concentration of the airflow can help better understand this issue. This can best be accomplished by sampling particles with a sampling probe at various locations within an engine. The present study is a continuation of a previous study that developed and evaluated a novel …
