Solvent Based 3d Printing Of Biopolymer/Bioactive Glass Composite And Hydrogel For Tissue Engineering Applications, Krishna Kolan, Yong Liu, Jakeb Baldridge, Caroline Murphy, Julie A. Semon, D. E. Day, Ming-Chuan Leu

Biological Sciences Faculty Research & Creative Works

Three-dimensional (3D) bioprinting is an emerging technology in which scaffolding materials and cell-laden hydrogels may be deposited in a pre-determined fashion to create 3D porous constructs. A major challenge in 3D bioprinting is the slow degradation of melt deposited biopolymer. In this paper, we describe a new method for printing poly-caprolactone (PCL)/bioactive borate glass composite as a scaffolding material and Pluronic F127 hydrogel as a cell suspension medium. Bioactive borate glass was added to a mixture of PCL and organic solvent to make an extrudable paste using one syringe while hydrogel was extruded and deposited in between the PCL/borate glass …

Efficient Algorithms For Solving Size-Shape-Topology Truss Optimization And Shortest Path Problems, Gelareh B. Sanjabi

Civil & Environmental Engineering Theses & Dissertations

Efficient numerical algorithms for solving structural and Shortest Path (SP) problems are proposed and explained in this study. A variant of the Differential Evolution (DE) algorithm for optimal (minimum) design of 2-D and 3-D truss structures is proposed. This proposed DE algorithm can handle size-shape-topology structural optimization. The design variables can be mixed continuous, integer/or discrete values. Constraints are nodal displacement, element stresses and buckling limitations.

For dynamic (time dependent) networks, two additional algorithms are also proposed in this study. A heuristic algorithm to find the departure time (at a specified source node) for a given (or specified) arrival time …

Developing A Career Development Assessment For Predicting Young Stem Graduates’ Employability And Career Barriers, Yi-Ching Lin

STEMPS Theses & Dissertations

The increased concern of declining STEM candidates could negatively impact the U.S. economy (Kelic & Zagnoel, 2009; Maltese & Tai, 2010). Previous studies suggest that the gap between the supply of STEM students in higher education and workface demand is not reflected merely in the number of STEM graduates but instead in the number of qualified STEM graduates who could satisfy STEM workforce demands (Kelic & Zagnoel, 2009; Lowell & Salzman, 2007). The current study used Rae’s employability theory (Rae, 2007) to develop an assessment for evaluating student’s career development in STEM during their higher education. Unlike other instruments focusing …

Learning While Using An Instructional Simulation, Tayyaba Batool

STEMPS Theses & Dissertations

Learner control is thought to be valuable by some scholars who believe that it allows learners to adapt instructions to their needs while reducing cognitive load (Mayer & Moreno, 2003). Although learner control offers some advantages to the learner, the importance of an instructor cannot be denied. In instructor-controlled settings the instructor provides guidance to the learners. Direct instructional guidance provides information to the learner that explains the concepts and procedures that are to be learned along with the instructional strategy support that is compatible with human cognitive architecture (Kirschner, Sweller, & Clark, 2006). This study compared the effects of …

What Do You Believe? School Leaders And An Ideology Of Achievement, Andrew T. Lloyd

Educational Leadership & Workforce Development Theses & Dissertations

Beliefs about achievement impact the educational experiences of students. The mainstream ideology of achievement espouses that anyone can be successful as long as they put forth effort and work hard. This belief fails to account for systemic barriers that have limited historically marginalized groups of people from achieving. Research has focused on the beliefs of teachers with scant research done on the beliefs of school leaders. This study focused on what school leaders believe about achievement and how it impacts their daily practice. In addition, the ideologies of the school leaders were compared and contrasted with an ideology rooted in …

Determining Critical Internesting And Foraging Habitats For The Conservation Of Sea Turtles In Gabon, Africa Using Satellite Tracking And Stable Isotope Analysis, Tiffany M. Dawson

Biological Sciences Theses & Dissertations

Understanding the horizontal and vertical habitat of olive ridley sea turtles (Lepidochelys olivacea), a threatened species, is critical for determining regions of protection that may effectively reduce bycatch, the largest threat to this species. Satellite transmitters were used to determine the movement and dive behavior of 21 female olive ridley turtles tagged in Pongara National Park, Gabon during the 2012, 2013, and 2015 nesting seasons. A switching state space model was used to filter the tracking data and categorize the internesting and post-nesting movements. Gridded utilization distribution (UD) home range analysis of tracking data revealed that the entire core habitat …

Investigation And Analysis Of The Fluctuating Brominated To Total Trihalomethane Ratio In The Virginia Beach Distribution System, Christopher Steven Mihalkovic

Civil & Environmental Engineering Theses & Dissertations

An increasing trend in the brominated-trihalomethane to total-trihalomethane concentration ratio from 2001 to 2016 in the Virginia Beach water distribution system was established and investigated. This study aimed at identifying factors contributing to fluctuations in trihalomethane speciation in finished water. Reservoir management practices, treatment processes, and source water conditions were examined to quantitatively and qualitatively discern the impact of their variations on finished water THM speciation. Data on water quality constituents and parameters from the Moore’s Bridges Treatment Facility and within the Virginia Beach distribution system were examined to interpret spatial and temporal relationships with trihalomethane concentrations using established research …

Finite Element Modeling Driven By Health Care And Aerospace Applications, Fotios Drakopoulos

Computer Science Theses & Dissertations

This thesis concerns the development, analysis, and computer implementation of mesh generation algorithms encountered in finite element modeling in health care and aerospace. The finite element method can reduce a continuous system to a discrete idealization that can be solved in the same manner as a discrete system, provided the continuum is discretized into a finite number of simple geometric shapes (e.g., triangles in two dimensions or tetrahedrons in three dimensions).

In health care, namely anatomic modeling, a discretization of the biological object is essential to compute tissue deformation for physics-based simulations. This thesis proposes an efficient procedure to convert …

Rules And Values In Virtual Optimization Of California Hydropower, Sonya F. P. Ziaja

Natural Resources Journal

Optimization models for California’s hydropower system are designed to be decision-support tools and aids for climate adaptation decision-making. In practice, they fall short of this goal. One potential explanation is that optimization models are not more successful because they are built on, and depend on, a misrepresentation of law and politics. The legal reality of California’s hydropower system is a web of networked jurisdictions of multiple federal and state agencies, with varying levels of coordination, long periods of legally obligated stability with rigid rules, and prone to conflict, but with multiple procedures for conflict resolution. Barriers to climate adaptation from …

Rediscovering Misinterpreted Concept Of Vospitaniye, Core Constituent Of Vygotskian Zpd, Through Scholar’S Socio-Cultural Actuality, Svetlana Mylnikova

Language, Literacy, and Sociocultural Studies ETDs

ABSTRACT

Lev Semyonovich Vygotsky, a renowned Russian psychologist, whose immediate family, academic surrounding, and scientific findings are typically scrutinized by scholars of past and present (Feingenberg, 1996, Kotik-Friedgut, 2008, 2011, Kuzmich, 2006, Vygodskaya & Lifanova, 1999, Yasnitsky, 2011, 2012) was the first to emphasize the holistic multidisciplinary approach to child development of pedology (child pedagogy) and distinguish two equally meaningful components of child education: obuchenie (teaching/learning process) and vospitanie (fostering). Even though Vygotskian theories are extensively employed in modern educational practices the intricacy of a complex unity of obuchenie and vospitanie in the process of education was overlooked as both …

The Ecology Of Acequias In The Mora Valley: Patterns, Processes And Place-Based Knowledge, Shannon Marie Rupert

Biology ETDs

In northern New Mexico, early settlements were clustered for protection of the people and access to water for domestic and agricultural uses was critical to their success. Irrigation ditches, known as acequias, brought water to the people, and were central to community life. These earthen ditches of varying lengths were built between one hundred and several hundred years ago, and most are still operational today. They divert water away from natural streams and across the landscape, through a system of man-made channels, until the unused water is diverted back into natural watercourses. These lateral channels appear to function as extensions …

Influence Of Tides And Mesoscale Eddies In The Ross Sea, Stefanie Lynn Mack

OES Theses and Dissertations

The Ross Sea is the most biologically productive region in the Southern Ocean. Primary production is controlled by dissolved iron (dFe), a limiting micronutrient. The main focus of this thesis, motivated by the PRISM-RS project, is to investigate how tides and mesoscale eddies affect the pathways of dFe to the surface ocean.

A regional ocean model with four hindcast simulations are used. Tidal forcing is added to simulations and mesoscale eddies are resolved by changing the horizontal grid resolution from 5 to 1.5 km. Simulations cover 1.5 years, ending at the time of the PRISM-RS cruise in early 2012. An …

To further understand the consumer's decision-making process the participant’s willingness to fly measured through affect (emotion), represented through the six universal facial expressions, (anger, disgust, fear, happiness, sad, and surprise) (Ekman & Friesen, 1971). This study surveyed participants from …

Reducing The Burden Of Rural Water Supply Through Greywater Reuse: A Case Study From Northern Malawi., Evan Newcomer, Courtney Boyd, Laban Nyirenda, Emmanuel Opong, Shannon Marquez, Rochelle Holm

Faculty and Staff Scholarship

Greywater reuse has potential for non-potable applications that conserve freshwater resources in water-stressed areas especially in sub-Saharan Africa. The feasibility of reusing greywater for domestic activities in a rural area of Malawi, Africa, was evaluated from microbiological and public acceptance perspectives. Median Escherichia coli concentrations for eight domestic greywater sources (handwashing, laundry, runoff from a tap apron, bathing, cleaning a home/kitchen, cleaning a water collection container, washing plates and soaking vegetables) ranged from 100 to >20, 000 colony forming units (cfu)/100 ml. Twenty-four of 47 greywater samples tested (51%) met the World Health Organization guideline for unrestricted use of greywater …
