Pharmaceutical Sorption to Lab Materials May Overestimate Rates of Removal in Lab-Scale Bioreactors
(Springer Science and Business Media LLC, 2022-11)Environmental contamination from pharmaceuticals has received increased attention from researchers in the past 20 years. As such, numerous lab-scale studies have sought to characterize the effects of these contaminants on ... -
Mapping liquid water content in snow at the millimeter scale: an intercomparison of mixed-phase optical property models using hyperspectral imaging and in situ measurements
(Copernicus Publications, 2022-01)It is well understood that the distribution and quantity of liquid water in snow is relevant for snow hydrology and avalanche forecasting, yet detecting and quantifying liquid water in snow remains a challenge from the ... -
Test of 90-Foot Post-Tensioned Concrete Girder with Unbonded Tendons
(American Concrete Institute, 2021-09)A full-scale post-tensioned concrete girder with unbonded tendons was tested to investigate whether, under vertical forces, a full flexural mechanism (with three hinging regions) would form, and what strand stress would ... -
International Journal of Multiphase Flow
(Elsevier BV, 2021-07)This study considers complex ice particles falling in the atmosphere: predicting the drag of such particles is important for developing of climate models parameterizations. A Delayed-Detached Eddy Simulation model is ... -
Empirical Bayes application on low-volume roads: Oregon case study
(Elsevier BV, 2021-12)ntroduction: This paper investigates the Empirical Bayes (EB) method and the Highway Safety Manual (HSM) predictive methodology for network screening on low-volume roads in Oregon. Method: A study sample of around 870 miles ... -
Reanalysis of Polythermal Glacier Thermal Structure Using Radar Diffraction Focusing
(American Geophysical Union, 2022-01)Ground-penetrating radar (GPR) is widely used on polythermal glaciers to image bed topography and detect internal scatter due to water inclusions in temperate ice. The glaciological importance of this is twofold: bed ... -
The Use of Fiber-Reinforced Polymers in Wildlife Crossing Infrastructure
(MDPI, 2020-02)The proven effectiveness of highway crossing infrastructure to mitigate wildlife-vehicle collisions with large animals has made it a preferred method for increasing motorist and animal safety along road networks around the ... -
Swimming Performance of Rainbow Trout and Westslope Cutthroat Trout in an Open-Channel Flume
(2020-06)We used an open-channel flume to characterize the swimming performance of Rainbow Trout Oncorhynchus mykiss and Westslope Cutthroat Trout Oncorhynchus clarki lewisi ranging nominally in fork length from 15 to 30 cm. With ... -
Biomineralization of Plastic Waste to Improve the Strength of Plastic-Reinforced Cement Mortar
(2021-04)The development of methods to reuse large volumes of plastic waste is essential to curb the environmental impact of plastic pollution. Plastic-reinforced cementitious materials (PRCs), such as plastic-reinforced mortar ... -
Hydraulic Analysis at the Interface of the Yellowstone River and the Huntley, Montana Irrigation Diversion Fish Bypass
(Montana State University, 2021-11)The nature-like bypass channel built to allow fish to circumvent the Huntley Diversion Dam on the Yellowstone River was constructed in 2015. A project was commissioned in 2019 to determine the effectiveness of the bypass ... -
In Situ Effective Snow Grain Size Mapping Using a Compact Hyperspectral Imager
(2021-02)Effective snow grain radius (re) is mapped at high resolution using near-infrared hyperspectral imaging (NIR-HSI). The NIR-HSI method can be used to quantify re spatial variability, change in re due to metamorphism, and ... -
Hydraulic characterization and removal of metals and nutrients in an aerated horizontal subsurface flow “racetrack” wetland treating oil industry effluent
(Elsevier, 2021-07)Constructed wetlands (CW) are an attractive technology due to their operational simplicity and low life-cycle cost. It has been applied for refinery effluent treatment but mostly single-stage designs (e.g., vertical or ... -
Variation of Small-Strain Shear Modulus of Unsaturated Silt under Successive Cycles of Drying and Wetting
(2020-07)A new framework is developed to extend an existing small-strain shear modulus (𝐺max) model to determine 𝐺max of unsaturated silty soils along different paths of the soil water retention curve (SWRC) including the scanning ... -
Kinetics of Calcite Precipitation by Ureolytic Bacteria under Aerobic and Anaerobic Conditions
(2019-05)The kinetics of urea hydrolysis (ureolysis) and induced calcium carbonate (CaCO3) precipitation for engineering use in the subsurface was investigated under aerobic conditions using Sporosarcina pasteurii (ATCC strain ... -
Using hyperspectral plant signatures for CO2 leak detection during the 2008 ZERT CO2 sequestration field experiment in Bozeman, MT
(2010-03)Hyperspectral plant signatures can be used as a short-term, as well as long-term (100-year timescale) monitoring technique to verify that CO2 sequestration fields have not been compromised. An influx of CO2 gas into the ... -
Practical Guidelines for Estimation of Rest Area Use on Rural Interstates and Arterial Highways
(2012-01)Rest areas perform a critical role in the highway network. These areas provide passenger vehicle occupants and heavy vehicle operators with an opportunity to use a restroom, walk around, stop for a meal, sleep for a period ... -
Remote Sensing of Weather and Road Surface Conditions
(2013-01)Advances in road weather sensing technologies have made noninvasive road weather sensors a valuable component in many intelligent transportation systems (ITS) applications. This study investigates the reliability of using ... -
Traffic Operations on Rural Two-Lane Highways: A Review on Performance Measures and Indicators
(2018-05)Two- lane highways constitute a large proportion of the highway system in the United States, particularly in rural areas. Performance evaluation on those highways is the basis for planning, upgrade, and improvement programs. ... -
Performance measures on two-lane highways: Survey of practice
(2018-11)Two-lane highways constitute a significant component of the highway system and serve an essential function for the movement of people and goods. The Highway Capacity Manual is primarily used for operational analysis on two ... -
Examining the Effect of Speed and Roadway Geometry on Crash Experience along a Rural Corridor
(2014-03)This paper presents a current investigation into crash experience along a 15.7-mile rural corridor in southwest Montana with the aim of better understanding crash causal factors along the corridor. The study utilized ten ...
