High Carbon Steel In Additive Manufacturing, Emmanuel Moore Ii, Devin Morton, Chid Agusiegbe

ME 4133/6133 Mechanical Metallurgy

The first known use of carbon steel dates back to 500 A.D. when a blacksmith mistakenly used iron ore as a primary material for smithing. This material, as the name suggests, is made up of both carbon and iron. This material, as one of the most abundant at the time, was used most frequently in European and Asian countries. “Carbon steel first appeared around the year 500 AD in Damascus steel swords as well as Japanese swords. They were prized for their sharp edges and sturdiness compared to other weapons of the era. The composition of these swords was very …

Integration Of Hadfield Steel Into Modern Body Armor, Jason T. Fridlund

ME 4133/6133 Mechanical Metallurgy

The increased lethality of recently fielded projectiles mandates a proportional escalation in armor performance. Recent advancements in ceramic technologies have allowed designers to incorporate harder but more brittle materials into hard armor designs to defeat yet more capable penetrating projectiles. Ceramics suffer from the feature of shattering, however, even when impacted by threats below their design parameters. While this shattering mechanism is used effectively to dissipate energy from high-energy rifle projectiles, it is wasted on low-energy projectiles, and can result in easily damaged lifesaving gear, both of which are undesirable in combat. In contrast, steel body armor has been used …

Near Infrared Spectroscopy Is Not A Surrogate Of Venous Occlusion Plethysmography To Assess Microvascular Resting Blood Flow And Function, Manuel Gomez, Alvaro N. Gurovich, Samuel Montalvo

International Journal of Exercise Science

International Journal of Exercise Science 15(2): 1616-1626, 2022. Near-infrared spectroscopy (NIRS) is a non-invasive technique that measures tissue perfusion using red blood cells oxygen saturation and venous occlusion plethysmography (VOP) is the gold standard to assess microvascular blood flow and function. The purpose of this study was to determine if NIRS can surrogate the microvascular blood flow assessment after an ischemic challenge obtained via VOP. Twenty apparently healthy subjects (10 males and 10 females), aged 18 to 35 years, were recruited for this single session study. NIRS probes were placed 40mm apart along the epicondylar muscles on the right forearm …

Stem And High School Students With Disabilities: A Qualitative Review Of The Research Literature, Scott Yamamoto Ph.D., Charlotte Y. Alverson Ph.D., Laura Mccoid-Goudy M.A.T., Hannah Castle B.A., Jacquelyn Burr M.Ed.

Journal of Science Education for Students with Disabilities

We conducted a qualitative review of the research literature on STEM (science, technology, engineering, mathematics) related to high school students with disabilities (SWD). We selected and analyzed 53 articles to answer two questions: (1) How are high-school SWD prepared for careers in STEM? (2) How are educators prepared to support high-school SWD for opportunities in STEM? In answering the first question, four qualitative themes emerged: (a) barriers to STEM, (b) increasing STEM opportunities, (c) STEM readiness in college and career, and (d) STEM identity. In answering the second question, three qualitative themes emerged: (a) individualizing learning and supports for SWD, …

Rocketry As Testing Platforms For Payloads, Pedro Llanos, Sathya Gangadharan

Faculty Research Projects

Design, assemble and launch small rockets as testing platforms to test small payloads which are flown aboard suborbital flight vehicles. We have successfully launched Level 1, Level 2 rockets, and we are in the process of finalizing the Level 3 rocket.

Practical experience for students in rockets and payloads is very valuable in the space industry, and it is something that would give them an advantage over other applicants. Students in Embry-Riddle Aeronautical University’s Payload and Integration class were given the opportunity to build Level 1 and Level 2 rockets and gain experience developing, testing, and integrating payloads into a …

Nasa/Zerog Microgravity Research, Pedro Llanos, Sathya Gangadharan

Faculty Research Projects

Embry-Riddle Aeronautical University and Carthage College proposed a technology demonstration that has several advantages over passive slosh control. Relative to slosh baffles, the proposed MAPMD technology has a lower total mass, a much higher degree of surface wave suppression, and less volumetric intrusion into the tank. The MAPMD concept also is optimized for cylindrical tanks (unlike elastomeric diaphragms, which work only in spherical pressure vessels), and currently requires no structural design changes to existing cylindrical propellant tanks.

The objective of the current research project under PI Kevin Crosby (Carthage College and University of Texas Health Science Center in San Antonio) …

Blue Origin's Suborbital Research: Messi/Mcximus, Pedro Llanos, Sathya Gangadharan

Faculty Research Projects

The following studies were conducted with Co-PIs Dr. Sathya Gangadharan (ERAU) and Kristina Andrijauskaite (University of Texas Health Science Center in San Antonio [UTHSCSA]).

MESSI Summary: This project was ERAU's second suborbital payload aboard Blue Origin’s New Shepard launched May 2, 2019. We analyzed the effects of suborbital flight stressors and various light conditions (red, white, no light) on the Arthrospira platensis, commonly known as Spirulina, aboard Blue Origin’s New Shepard launch vehicle. Commercially available cyanobacterium species were cultivated and closely monitored in mother colonies several months before the flight. The aim was to estimate biomass production and growth as …
