Studying and developing the thin film membranes for reverse osmosis application
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Desalination by semi-permeable membranes is the most applicable method of water-salt separation, where reverse osmosis (RO) account for the major portion of the overall water...
In vitro characterization of Nudt16 orthologs by sequence and function provide evidence supporting a nuclear RNA degradation pathway
(University of Missouri--Columbia, 2009)
Nudt16, previously called X29, is known to be a metal-dependent decapping enzyme expressed in mammals and Xenopus . Nudt16 has been proposed to be the catalytic component of a previously unknown nuclear RNA degradation ...
Hierarchical physical-statistical forecasting in the atmospheric sciences
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A class of hierarchical Bayesian models is introduced for Physical-Statistical forecasting purposes in the Atmospheric Sciences. The first project describes a methodological...
Digestible lysine and threonine requirements of male turkeys and their effects on performance of male turkeys fed practical diets to market age
(University of Missouri--Columbia, 2008)
Seven experiments were conducted to determine the minimum requirements of digestible lysine (dLys) and digestible threonine (dThr) from 1 to 21 weeks of age for male turkeys. Requirement values were similar to NRC (1994) ...
Small-medium enterprise experiences of financial service in urban and rural settings : a phenomenological study of a changing community finance landscape and the sustainable finance narrative
(University of Missouri--Columbia, 2021)
Relationships between small-medium size businesses ('SME') and community banks are complex, meaningful, and often described as characteristically "opaque". This study offers a conceptual framework for exploring this ...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
Distributed watershed hydrologic/water quality (H/WQ) models are ubiquitous tools for watershed management. Despite advancements, there remain impediments for end-users. This study presents a practical framework for use ...
