The Influence of Air Cleaners on Indoor Particulate Matter Concentrations and Oxidative Potential in Residential Households in Beijing
(2018-01-03)In many developing regions where poor air quality is endemic, there is a rapidly growing number of air filtration devices available to clean indoor air. However, few studies have been performed to assess their effectiveness. ... -
An Integrated Framework to Evaluate the Impact of Preconstruction Planning on Out-of-Sequence Work
(2020-08)For decades, the construction industry has faced a well-documented, persistent decline in its productivity levels. The reasons behind the declining productivity rates have been tackled by extensive research; however, some ... -
An Integrated Framework to Quantify the Impact of Competency factors on Project Performance
(2020-05)Construction companies measure their performance by how well a construction project delivers relative to their goals. The performance of construction projects is governed by merging many events and interactions with different ... -
Investigation of Warm Mix Asphalt Additives Using the Science of Tribology to Explain Improvements in Mixture Compaction
(2012-12-23)Part of asphalt pavement production is the compaction process of loose mix. The quality of compaction process has a profound impact on the quality of the final product. With the advent of Warm Mix Asphalt (WMA) additive ... -

Long-Term Performance of Radon Barriers in Limiting Radon Flux from Four Uranium Mill Tailings Containment Facilities
(2018-06-22)ABSTRACT Compacted clay covers have traditionally been constructed to contain Uranium mill tailings (UMT) at disposal sites throughout the United States. These clay covers, typically referred to as Radon (Rn) barriers, ... -
Managing climate risks in agriculture and hydropower by coupling prediction and multi-purpose reservoir models in the Blue Nile Basin, Ethiopia
(2018)The Blue Nile Basin in Ethiopia is a critical water resource for the nation and continent, subject to spatial and temporal variations in climate that adversely impact local communities. Extreme conditions, e.g. drought and ... -
Matching Surface Water and Groundwater Elevations in Mud Lake using HydroGeoSphere
(2013-05-19)Groundwater and surface water models are becoming more a more prominent method to approximate the complex physical flow processes that are encountered in our natural environment. These models rarely integrate surface water ... -
MEASURING DYNAMIC PROPERTIES OF WIND TURBINE FOUNDATION SOIL IN RESONANT COLUMN - ISSUES AND CHALLENGES
(2014-08-22)Wind turbine foundations are subject to large dynamic wind loads. The horizontal wind loads create large shear forces and moments on the foundation, which may result in critical issues related to the stability and deformation ... -
Medical Supplies and Their Implications for Sustainability in the COVID-19 Pandemic
(2022-05)The 21st century saw the emergence of several pandemics thus far, with the most recent one still affecting us today, the COVID-19 pandemic. Throughout the COVID-19 pandemic, there has been a greater focus on medical supplies ... -
Meteorological drivers of oxygen depletion in Lake Mendota
(2015-05-18)Physical, chemical and biological lake processes are sensitive to climate. Global circulation models generally predict future increases in air temperature, but are more uncertain in predictions of other meteorological ... -
