Ambulatory assessment of physical pain, emotional distress, and alcohol use
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The available research suggests that many individuals with chronic pain drink alcohol to manage their pain. However, few studies have examined the association of alcohol and pain...
Adsorption interactions of UV-aged microplastic particles with sulfamethazine
(University of Missouri--Columbia, 2022)
Due to growing plastic demand and production without proper waste management, microplastics have become common around the world throughout diverse systems. At the same time, increased detection of antibiotics in the ...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...
Interaction of organophosphorus insecticide (Ciovap(R)) with phenothiazine anthelmintic in sheep with or without Haemonchus and Trichostrongylus species infection

"This study was undertaken to examine the extent of cholinesterase inhibition and clinical effects of repeated topical application of the organophosphorus insecticide (Ciovap (R)) and the oral administration of phenothiazine ...
Generation, collection and characterization of nanoparticles and their diffusion in arbitrary tumor and normal tissue geometry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanoparticles have unique electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of the bulk materials. Because of this...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...
Flexure shear response in fatigue of fiber reinforced concrete beams with FRP tensile reinforcement
(University of Missouri--Columbia, 2007)
of polypropylene fibers by volume, individual compressive tests were performed on both lab-mix and ready mix concrete specimens. In the lab, concrete mixes with 0.0%, 0.5%, and 1.0% by volume, fibrillated polypropylene fibers were produced. Along with these...
Dispositional antecedents of career success : a social network perspective
