The contributions of soy protein quaternary structures on viscoelastic properties of polyethylene oxide/soy protein composites
(Wichita State University, 2020-05-01)More than four-and-a-half million acres of Kansas land were covered in soybeans in 2018, with Kansas farmers harvesting an average of 44 bushels per acre worth a combined total of $1.6 billion. Soybeans are mostly used for ... -
The development of heparan sulfate within the glycocalyx
(Wichita State University, 2020-07)A key to protecting vessel health occurs at the interface between circulating blood and endothelial cells. Strategically located at this interface is the endothelial glycocalyx, the first “line of protection” for blood ... -
The development of the dynamic mechanical analyzer (DMA) calibraton and testing procedures
(Wichita State University, 2013-12)Dynamic mechanical analysis (DMA) is the most preferred thermal analysis technique for determining the glass transition temperature (Tg) of polymer matrix composites because it is more sensitive to Tg measurements than ... -
The effect of lower limb exoskeleton alignment on knee rehabilitation efficacy
(MDPI, 2022-07-12)This study focuses on a musculoskeletal analysis of human lower extremity and associated muscle forces during different rehabilitative tasks and exoskeleton alignment models. By changing the size and orientation of the ... -
The effectiveness of Smart Compose: An artificial intelligent system
(Association for Industry, Engineering and Management Systems (AIEMS), 2020-06)The growth of artificial intelligence (AI) technologies in everyday life and manufacturing are expected to reduce the mental workload of a user or human operator and increase their efficiency. In industrial systems, such ... -
The effects of authentic based instruction on long term retention and application, student engagement, and student motivation
(Wichita State University, 2013-05)This research attempted to determine if there was a benefit to authentic based instruction over traditional lecture based instruction. Two units were taught in the Social Studies curriculum area, the first using lecture ... -
The effects of laminar and oscillatory fluid shear stress on microvascular endothelial cells
(Wichita State University, 2019-05)Cardiovascular disease (CVD) is one of the most prevalent causes of death in the United States, being responsible for nearly one in every three deaths. Cellular mechanics related to CVD are often studied using human umbilical ... -
The effects of soy protein on viscoelastic behaviors of polymer materials
(Wichita State University, 2020-12)The interest in “green” materials, or materials made with biocompatible and biodegradable components is growing, including research into natural polymers, namely proteins and polysaccharides, due to their structures and ... -
The impact of continuous improvement methods on a firm's competitive priorities: empirical evidence from the customers perspective in the aerospace industry
(Wichita State University, 2018-05)The purpose of this research paper is to examine the actual and perceived results from the customer perspective on the Competitive Priorities of cost, quality, delivery, flexibility and innovation stemming from Continuous ... -
The impact of fluid shear stress on the morphology of human dermal microvascular endothelial cells
(Wichita State University, 2021-07)As blood flows through blood vessels, the fluid exerts a shear stress on the endothelial cells that line the vasculature. The current perception in the literature is that all endothelial cells will align and elongate in ... -
The impact of passive shoulder exoskeletons during simulated aircraft manufacturing sealing tasks
(Elsevier, 2022-08-03)Aircraft manufacturing involves an operation called sealing during which fuselage joints are sealed utilizing a sealant and smoothing tool, requiring motion of a worker's arms at heights below the elbow to overhead. The ... -
The intersection of energy, healthcare and climate
(Wichita State University, 2015-05)The reduction of energy use in hospitals as energy intensive units is critical to the overall goals of lowering the cost of healthcare and emissions from those facilities. Hence, the assessment and identification of key ... -
