Course Elements that Impact Performance and Behavior in Undergraduate Science Classes
(2020-07-14)
Using evidence-based approaches to teaching can help instructors and institutions
improve student experiences in the classroom. By understanding the ways that different
classroom environments and activities impact students, ...
Synthesis and Characterization of Copolymers: Tuning Material Properties of Polythiophenes and Epoxy-Thiol Polymer Networks, and Application of Low-Field NMR Spectroscopy to Multicomponent Polymer Systems
(2020-07-14)
Society’s demands for more products and more energy places great strain on the industries responsible for producing them. Polymers present the opportunity to replace many of the “traditional” materials and open the door ...
Quantifying Pavement Preservation Performance Using Probabilistic Deterioration Modeling
(2020-07-14)
Throughout the last few decades, the pavement industry has slowly transitioned from construction and rehabilitation to pavement preservation. Pavement preservation can be described as a proactive approach for protecting ...
Microbiological Evaluation of Commercially Manufactured Animal Feeds to Determine Presence of Salmonella, Escherichia coli and Clostridium perfringens
(2020-07-14)
Animal feed can potentially expose animals to pathogens which may lead to infection or colonization of the gastrointestinal tract (GIT). Feeds can become contaminated with bacterial pathogens during harvesting/transportation ...
Evaluation of Escherichia coli and Coliforms in Aquaponic Water for Produce Irrigation
(2020-07-14)
With the increase of commercialized aquaponics, concerns associated with pathogens in aquaculture water transferring to the produce have increased. The FDA Produce Safety Rule states water used for irrigation purposes that ...
Field Assessment of Cold Recycling Technologies Used for Pavement Preservation
(2020-07-14)
Cold recycling of asphalt concrete pavements is a widely practiced technique used to prolong pavement life as a low-cost preservation method. Research in recycled materials has become necessary to further evaluate the ...
Developing a Practical Tool for Integrating Green Infrastructure into Cost-Effective Stormwater Management Plans
(2020-07-14)
Urban stormwater management today aims to manage both the quantity and quality of stormwater runoff. Best management practices (BMPs) such as detention basins have long been used to address runoff quantity objectives, and ...
MEMS and Additively Manufactured Micro-Mechanical Isolator
(2020-07-14)
The purpose of the research effort was the development and evaluation of mechanical
isolators. Some MEMS sensors have a known vulnerability to high frequency vibrations in various
environments. The nature of the ...
Evaluation of Deficit Irrigation Strategies and Management Zones Delineation for Corn Production in Alabama
(2020-07-14)
The adoption of center pivot irrigation in Alabama has increased in recent years. The reason is that farmers are achieving high crop yield by avoiding crop water stress. Although, irrigation adoption has increased, Alabama ...
Effect of maternal and post-hatch dietary 25-hydroxycholecalciferol supplementation on broiler chicken growth characteristics and skeletal muscle satellite cell activity
(2020-07-14)
Including the vitamin D3 (D3) metabolite, 25-hydroxycholecalciferol (25OHD3) in broiler diets, has been shown to enhance the proliferative activity of skeletal muscle satellite cells (SC), induce the expression of pro-myogenic ...
Utilizing Cast Antlers for Profiling Quality and Annual Repeatability of Antler Characteristics in a Nutritionally Stable Environment for White-tailed Deer
(2020-07-14)
Antlers are often used as indicators of management effectiveness in deer populations, and increasing antler size is frequently a management objective. Thus, managers are interested in assessing antler characteristics and ...
