Coliform Contamination in private well water on the Crow Reservation
(2018-10)Emery Three Irons is a master’s level graduate student in the Department of Land Resources and Environmental Sciences (LRES) at Montana State University (MSU). Advised by Scott Powell, Ph.D., who is an Associate Professor ... -
Impact of an automated hand hygiene monitoring system and additional promotional activities on hand hygiene performance rates and healthcare-associated infections
(2019-07)Objective: Determine the impact of an automated hand hygiene monitoring system (AHHMS) plus complementary strategies on hand hygiene performance rates and healthcare-associated infections (HAIs). Design: Retrospective, ... -
A Novel Gastric Spheroid Co-culture Model Reveals Chemokine-Dependent Recruitment of Human Dendritic Cells to the Gastric Epithelium
(2019-03)Background & Aims Gastric dendritic cells (DCs) control the adaptive response to infection with Helicobacter pylori, a major risk factor for peptic ulcer disease and gastric cancer. We hypothesize that DC interactions ... -
Randomized controlled trial evaluating the antimicrobial efficacy of chlorhexidine gluconate and para-chloro-meta-xylenol handwash formulations in real-world doses
(2019-06)Chlorhexidine gluconate-based soaps have become the gold standard for handwashing in critical care settings and para-chloro-meta-xylenol is an effective alternative antibacterial active ingredient. This study benchmarked ... -
Who goes in and out of patient rooms? An observational study of room entries and exits in the acute care setting
(2019-05)The objective of this study is to determine what percentage of patient room entries and exits (opportunities) are attributed to health care personnel (HCP) and non-HCP. A total of 14,876 opportunities were observed by ... -
Quorum sensing inhibition as a promising method to control biofilm growth in metalworking fluids
(2019-04)Microbial contamination in metalworking systems is a critical problem. This study determined the microbial communities in metalworking fluids (MWFs) from two machining shops and investigated the effect of quorum sensing ... -
Killer whales redistribute white shark foraging pressure on seals
(2019-04)Predatory behavior and top-down effects in marine ecosystems are well-described, however, intraguild interactions among co-occurring marine top predators remain less understood, but can have far reaching ecological ... -
Beyond MRV: high-resolution forest carbon modeling for climate mitigation planning over Maryland, USA
(2019-04)Forests are important ecosystems that are under increasing pressure from human use and environmental change, and have a significant ability to remove carbon dioxide from the atmosphere, and are therefore the focus of policy ... -
Predatory fish invasion induces within and across ecosystem effects in Yellowstone National Park
(2019-03)Predatory fish introduction can cause cascading changes within recipient freshwater ecosystems. Linkages to avian and terrestrial food webs may occur, but effects are thought to attenuate across ecosystem boundaries. Using ... -
Nickel-Catalyzed Stille Cross Coupling of C-O Electrophiles
(2019-04)Aryl sulfamates, tosylates, and mesylates undergo efficient Ni-catalyzed cross coupling with diverse organostannanes in the presence of relatively unhindered alkylphosphine ligands and KF. The coupling is valuable for ... -
The voltage sensing phosphatase (VSP) localizes to the apical membrane of kidney tubule epithelial cells
(2019-04)Voltage-sensing phosphatases (VSPs) are transmembrane proteins that couple changes in membrane potential to hydrolysis of inositol signaling lipids. VSPs catalyze the dephosphorylation of phosphatidylinositol phosphates ... -
Simulation-based validation of spatial capture-recapture models: A case study using mountain lions
(2019-04)Spatial capture-recapture (SCR) models have improved the ability to estimate densities of rare and elusive animals. However, SCR models have seldom been validated even as model formulations diversify and expand to incorporate ... -
Langmuir's Theory of Adsorption: A Centennial Review
(2019-04)The 100th anniversary of Langmuir's theory of adsorption is a significant landmark for the physical chemistry and chemical engineering communities. Despite its simplicity, the Langmuir adsorption model captures the key ... -
Comparison of Combinatorial Signatures of Global Network Dynamics Generated by Two Classes of ODE Models
(2019-04)Modeling the dynamics of biological networks introduces many challenges, among them the lack of first principle models, the size of the networks, and difficulties with parameterization. Discrete time Boolean networks and ... -
Was the First Public Health Campaign Successful?
(2019-04)The US tuberculosis (TB) movement pioneered many of the strategies of modern public health campaigns. Using newly transcribed mortality data at the municipal level for the period 1900-1917, we explore the effectiveness of ... -
Identifying occupancy model inadequacies: can residuals separately assess detection and presence?
(2019-04)Occupancy models are widely applied to estimate species distributions, but few methods exist for model checking. Thorough model assessments can uncover inadequacies and allow for deeper ecological insight by exploring ... -
Are Booster Seats More Effective than Child Safety Seats or Seat Belts at Reducing Traffic Fatalities among Children?
(2019-01)In an effort to increase booster seat use among children, the National Highway Traffic Safety Administration is encouraging state legislators to promote stricter booster seat laws, yet there is a paucity of information on ... -
A review of the mechanisms of mineral-based metabolism in early Earth analog rock-hosted hydrothermal ecosystems
(2019-02)Prior to the advent of oxygenic photosynthesis similar to 2.8-3.2Ga, life was dependent on chemical energy captured from oxidation-reduction reactions involving minerals or substrates generated through interaction of water ... -
Absent autonomy: Relational competence and gendered paths to faculty self-determination in the promotion and tenure process
(2018-09)This research examines ways in which men and women university faculty sought self-determination in the promotion and tenure (P&T) process. Self-Determination Theory (SDT; Deci & Ryan, 2012) research tends to view autonomy ... -
Operational efficiency, patient composition and regional context of U.S. health centers: Associations with access to early prenatal care and low birth weight
(2019-04)Community health centers (CHCs) provide comprehensive medical services to medically under-served Americans, helping to reduce health disparities. This study aimed to identify the unique compositions and contexts of CHCs ...
