Carbon Nanotube Thermal Interfaces And Related Applications, Stephen L. Hodson

Open Access Dissertations

The development of thermal interface materials (TIMs) is necessitated by the temperature drop across interfacing materials arising from macro and microscopic irregularities of their surfaces that constricts heat through small contact regions as well as mismatches in their thermal properties. Similar to other types of TIMs, CNT TIMs alleviate the thermal resistance across the interface by thermally bridging two materials together with cylindrical, high-aspect ratio, and nominally vertical conducting elements. Within the community of TIM engineers, the vision driving the development of CNT TIMs was born from measurements that revealed impressively high thermal conductivities of individual CNTs. This vision was …

Leveling The Playing Field: Teacher Perception Of Integrated Stem, Engineering, And Engineering Practices, Bridgette Fincher

Graduate Theses and Dissertations

The purpose of this study was to describe the perceptions and approaches of 14 third-through-fifth grade Arkansan elementary teachers towards integrative engineering and engineering practices during 80 hours of integrated STEM professional development training in the summer and fall of 2014. This training was known as Project Flight. The purpose of the professional development was to learn integrated STEM content related to aviation and to write grade level curriculum units using Wiggins and McTighe’s Understanding by Design curriculum framework. The current study builds upon on the original research.

Status Of Nuclear Security Education And Research In Bangladesh And Looking Forward, Md. Shafiqul Islam, Md. Mobasher Ahmed

International Journal of Nuclear Security

Bangladesh uses category I of nuclear materials and category 1-5 of radioactive materials in the field of research, medical and industries. The Government is going to implement its first nuclear power plant under an IGA between the Bangladesh and Russian Governments. With the emerging global nuclear and radiological terrorism by potential adversaries, enhancing nuclear security is the paramount importance for the country. The paper has found no established communication channels among stakeholders in order to work in a coordinated and collaborative manner for strengthening the nuclear security. This has resulted lacking importance of education, research, training and knowledge management initiatives …

Examining Bridges Between Informal And Formal Learning Environments: A Sequential Mixed Method Design, Dagen L. Valentine

Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship

The purpose of this sequential mixed method study was to identify schools implementing a technology-based engineering design intervention in a way that connects or bridges formal learning environments of the school-day to informal learning environments such as afterschool programs. Further, this study investigated educators’ decisions that enabled or facilitated bridging between formal and informal learning environments. This cooperation and/or linking between informal and formal learning time is bridging. Participants included public schools (n=16) in Eastern Nebraska that incorporated the Nebraska Wearables Technology (WearTec) program at their school, club or Out-of-School-Time program during the 2015-2016 school year. Three of the schools …
