Small Satellite Conference

The AERO (Auroral Emission Radio Observer) and VISTA (Vector Interferometry Space Technology using AERO) missions will advance auroral radio science and radio interferometry technology. AERO is intended to qualify and validate electromagnetic vector sensor technology in space while also answering key scientific questions about the nature and sources of auroral radio emissions. These questions cannot be addressed from the ground due to shielding by the ionosphere. VISTA, together with AERO, will provide the first demonstration of interferometric imaging, beamforming, and nulling using electromagnetic vector sensors at low frequencies (100 kHz – 15 MHz) using Space based sensors.

Sustainability And Resilience In Small-Scale Land-Based Livelihoods In Maine, Sam Calvino Cowan

Capstone Collection

Global sustainability can be understood as an oxymoron since no global society has ever managed to be truly sustainable. Effective examples of sustainable and resilient societies do exist on a much smaller scale, however. This study examined small-scale land-based livelihoods, or homesteads, to understand what factors contributed to their environmental sustainability and climate resilience. Through participant observation as well as long form loosely structured interviews, conceptions of resilience and sustainability on the homestead scale were developed. By understanding the philosophical, spiritual, and political frameworks that inform the homesteaders’ approaches to their livelihoods, three deliverables were developed to exemplify these approaches …

The Sermons Of The Appalachian Preaching Mission 1958-1977, Robert Ellison, Thomas Hilton

ASA Annual Conference

The Appalachian Preaching Mission was an annual event that took place in Johnson City and other Tennessee cities from 1955 to 1986. A 1968 history of the Mission states that its purpose “was to allow the people of the area to hear great preachers that they would not ordinarily have the opportunity to hear.” Some of those preachers lived in or near Johnson City; others came from as far away as Arizona, California, Georgia, Pennsylvania, and Texas.

Perovskite Solar Cells, Liqiu Zheng Dr., Tyler Hurst, Zhongrui Li

Georgia Journal of Science

The semiconductor perovskite CsPbBr₂I was doped with Mn²⁺ to modulate its optical and photovoltaic performance. The Mn²⁺-doped CsPb_0.9Mn_0.1Br₂I exhibited improved crystalline quality. Ultraviolet and visible spectroscopy of Mn²⁺-doped CsPb_0.9Mn_0.1Br₂I revealed enhanced absorption capacity. Although the efficiency was not as good as desired, the enhanced light absorption of CsPb_0.9Mn_0.1Br₂I still boosted the photovoltaic performance when it was utilized as a light absorber in perovskite solar cells, along with a low-cost carbon electrode. Compared with its counterpart …

Studying The Physical And Biological Characteristics Of Denture Base Resin Pmma Reinforced With Zro2 And Tio2 Nanoparticles, Fatin A. Asim, Entessar H.A. Al-Mosaweb, Wafaa A. Hussain

Karbala International Journal of Modern Science

Polymethyl methacrylate (PMMA) suffers from poor mechanical properties that limit its application in the bio-medical field. In this study, PMMA was reinforced with zirconium dioxide (ZrO2) and titanium dioxide (TiO2) nanopar-ticles; subsequently, the hardness, porosity, biocompatibility, bacterial adhesion, and colonization of the reinforced PMMA with various oxide nanoparticles were characterized. The results of this study indicated that reinforced material inhibits bacterial growth and decreases bacterial adhesion by decreasing porosity and increasing PMMA hardness. Based on the findings, 3 wt% PMMA-ZrO2 and 3 wt% PMMA-ZrO2 -TiO2 composites significantly inhibited bacterial growth and adherence while maintaining hemolysis PT and INR and enhancing …

The Distinction Of Logical Decision According To The Model Of The Analysis Of Brain Signals (Eeg), Akeel Abdulkareem Al-Sakaa, Zaid H. Nasralla, Mohsin Hasan Hussein, Saif A. Abd, Hazim Alsaqaa, Kesra Nermend, Anna Borawska

Karbala International Journal of Modern Science

Recently, brain signal patterns have been recruited by researchers in different life activities. Researchers have studied each life activity and how brain signal patterns appear. These patterns could then be generalised and used in different disciplines. In this paper, we study the brain state during decision making in a lottery experiment. An EEG device is used to capture brain signals during an experiment to extract the optimal state for logical decision making. After collecting data, extracting useful information and then processing it, the proposed method is able to identify rational decisions from irrational ones with a success rate of 67%.
