Optical Constants of Silicon Carbide for Astrophysical Applications. II. Extending Optical Functions from Infrared to Ultraviolet Using Single-Crystal Absorption Spectra
(American Astronomical Society, 2009)
of this structure below λ ∼ 4 μm. The onset of strong UV absorption for pure SiC occurs near 0.2 μm, but the presence of impurities redshifts the rise to 0.33 μm. Optical functions are similarly impacted. Such large differences in spectral characteristics due...
Alcohol/HIV-Induced Neurodeficit and Circumvention by Neuroprotective Agent
(2023)
Alcohol Use Disorder (AUD) remains a major problem in the United States, with usage varying between acute (binge) and chronic (heavy usage) staging. Alcohol Use Disorders affect 14.5 million people, with 9 million men and ...

Predicting RNA secondary structures using physics-based modeling and evolutionary inferences
(University of Missouri--Columbia, 2022)
tool for structure determination. RNAs have four types of nucleotides: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U). Through base pairing and tertiary interactions between nucleotides, RNA can form secondary (2D) and tertiary (3D) structures...
Using the physical classroom environment as a tool for learning : a case study
(University of Missouri--Columbia, 2011)
Literacy has been identified as the main goal of K-12 education in the United States today, for its value to individuals and to society. Balanced literacy and related methods are pedagogically based on the constructivist premise that intrinsically...
Exploration of fecal microbial transfer and the competitive exclusion concept in broilers as a possible alternative to antibiotic growth promoters
(University of Missouri--Columbia, 2021)
particularly associated with culture-based surveys. Although there is increasing evidence for a connection between feed efficiency and gut microbiota in broilers, the relationship is still not yet fully understood. Future research on the impact of FMT...
Domain-concept mining : an efficient on-demand data mining approach
(University of Missouri--Columbia, 2008)
Traditional brute-force association mining approaches, when applied to large datasets, are thorough but inefficient due to computational complexity. A low global minimum probability threshold can worsen this complexity by ...
Common Plan Time at the middle school level

Development and analysis of a socio-scientific reasoning assessment : application of computer automated scoring and rasch analysis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Scientific literacy (SL) as an idea is considered by many to be one of the main goals of science education. This study focuses on Roberts' (2007) second ...
Missouri superintendents' perception of a sense of urgency to improve student academic performance
(University of Missouri--Columbia, 2010)
This exploratory study examined the relationship between superintendents' perceived sense of urgency and student academic performance. More specifically, the study examined the leadership of Missouri superintendents based upon a district's Annual...
Halal food certification, financial performance, and sustainability reporting : comparative study of food and beverage firms in Malaysia and Indonesia
(University of Missouri, College of Agriculture, Food and Natural Resources, 2022)
halal certification affects the caliber of sustainability reporting. Second, the outcome offers concrete evidence of how the halal certification affects sustainability reporting from the perspectives of Malaysia and Indonesia. The conclusion...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
, and of cobalt rod-based phosphate ISEs were satisfactory for measuring N, P, and K ions over typical ranges of soil concentrations. The nitrate ISEs, when used in conjunction with the Kelowna extractant (0.25M CH₃COOH + 0.015M NH₄F), provided soil NO₃-N values...
