Small Satellite Conference
The current state of the art for small satellite chemical propellant tanks is limited in design customization, is expensive, and is volumetrically inefficient within the cuboid volumes of small satellite buses. Space Dynamics Laboratory and Velo3D Inc. partnered to develop propulsion tank technology that solves these challenges using metal additive manufacturing (AM). We designed, analyzed, built, heat-treated, post-machined, precision cleaned, and qualification tested a titanium 6A14V volume-optimized 3D-printed propulsion tank with an integral printed propellant management device (PMD). They are rated for a maximum expected operating pressure of 400 psi. These tanks are 3D-printed in the desired cuboid mission geometries …
Amsat-Oscar-7: 50 Years In A Sun-Synchronous Orbit - And Still Counting - Confirmation Of The Long-Term Solar Gravity-Gradient Perturbation, Jan A. King, Karl Meinzer

Small Satellite Conference
The first Delta launch vehicle to launch multiple secondary payloads was Δ-104. Carried, as the 2nd piggyback payload on that mission was an amateur radio Smallsat, AMSAT-OSCAR-7 (AO-7). The launch, on 15 November 1974, was to a 1460 km SSO. This spacecraft, as its name suggests, was the 7th in an on-going series of spacecraft operating in the Amateur Satellite Service. The amazing story associated with the mission of this small satellite is being reported elsewhere in these proceedings. While the particulars of this satellite's lifetime are exciting, we didn't particularly expect this "old bird's set of tricks …

Kwad - Ksu All Weather Autonomous Drone, Nick Farinacci, Sebastian Gomez, Stewart Baker, Ed Sheridan
Symposium of Student Scholars
"KWAD" or "KSU all-Weather Autonomous Drone" project was sponsored by Ultool, LLC to the KSU Research and Service Foundation to create a lightweight drone capable of capturing HD video during all-weather operations. The conditions of all-weather operation include rainfall of one inch per hour and wind speeds of up to twenty miles per hour. In addition, a global minimum structural safety factor of two is required to ensure the system's integrity in extreme weather conditions. Potential mission profiles include autonomous aerial delivery, topological mapping in high moisture areas, security surveillance, search and rescue operations, emergency transportation of medical supplies, and …
Podium Presentation: Promoting Holistic Health: Impact Of Vocati On The Spiritual And Moral Development In Youth, Joann Long, Jeremy Smith
Podium Presentation: Promoting Holistic Health: Impact Of Vocati On The Spiritual And Moral Development In Youth, Joann Long, Jeremy Smith
2022 Providence Nurse Research Conference
Background: Approximately one out of every six individuals are adolescents between the ages of 10 to 19. Promoting health and reducing risks for this age group has life-long health and societal consequences. Evidence suggests positive and negative risk-taking behaviors cluster in this population. Models for the promotion of positive youth development have shifted in focus from avoidance of risk-taking behaviors to emphasis on psychosocial competence and holistic well-being. Evidence suggests spiritual wellbeing, regardless of conceptual definition, is more often than not associated with positive health outcomes and development in youth. However, few studies have included spiritual and moral constructs in …
African Resistance To European Colonial Aggression: An Assessment, Nigel Tussing
African Resistance To European Colonial Aggression: An Assessment, Nigel Tussing
Africana Studies Student Research Conference (2013-2019)
When observing African resistance to colonialism one plainly sees that there was quite a bit of non-military resistance. However, military resistance played a large role in helping the cause of the native people of Africa. It had success such as Ethiopia’s ability to remain independent and the Chilembwe insurrection; it also had its failures such as lack of technology and lack of unity. Through careful examination of these ideas we can further understand the success and failure of African military resistance to colonialism.
From Missional Worship To Missional Living And Back Again, Chris Schoon Thd
From Missional Worship To Missional Living And Back Again, Chris Schoon Thd
Symposium on Worship Archive
Mission and worship have quite a history of being kept separate from each other. But what if they were intended to flow into each other, to be mutually edifying? In this session, we’ll explore characteristics of a missional approach to worship, paying attention to how our communal worship forms us for a missional way of life and how this missional living in turn pours back into our communal worship.

Lesson 8: Spanish Missions In Florida, Elizabeth Rasmussen
Hispanic Heritage of Florida Conference 2012
The purpose of this lesson is for students to use maps and reading passages in order to learn about the influence of the Spanish mission system on Florida. The Spanish Mission system was influential to the establishment of formal political systems in Florida.
