Modeling the influence of climate and management practices on water quality in Goodwater Creek experimental watershed
(University of Missouri--Columbia, 2006)
The objective of this study was to determine relationships among weather, runoff, water quality, and best management practice (BMP) implementation in reducing atrazine losses in the 7,250-ha Goodwater Creek Experimental Watershed in NE Missouri...
Assessing costs and environmental impacts of municipal food waste treatment options in Columbia, Missouri : a decision support tool integrating life cycle analysis and robust optimization
(University of Missouri--Columbia, 2021)
and targets, decisionmakers need data-driven analysis to understand both the costs and environmental impacts of their plans. This study develops a decision support tool applied in Columbia, Missouri, USA, with aims to model the economic and environmental...
A quarterly econometric model of the United States beef sector
(University of Missouri--Columbia, 1982)
The United States beef sector has been modeled in many studies, perhaps, because beef represents a large proportion of the consumer food dollar and agriculture’s income. The predictive performance of these models has been, however, quite...
A content analytic comparison of news frames in English- and Spanish-language newspapers
(University of Missouri--Columbia, 2006)
As the Hispanic population in the United States tops 40 million people, it is important to look at ways in which American and Latino cultures compare and interact. More than any other U.S. immigrant group, Hispanics rely ...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity of maize facilitate its use...
Milk substitutes, powdered skimmilk for raising calves
(University of Missouri--Columbia, 1917)
Text from introduction: This thesis is a discussion, from the standpoint of our present knowledge of the fundamental principles of animal nutrition, of the possibility of raising calves on "milk substitutes". The experimental ...
LC-MS/MS method development for quantitative analysis of cyanogenic glycosides in elderberry and lipid peroxidation products in mice
(University of Missouri--Columbia, 2021)
of AE cultivars studied ranged from between 0.12-6.38 [micro-gram]/g. In pressed juice samples, the concentration range measured was 0.29-2.36 [micro-gram]/mL and in seeds the amounts was 0.12-2.38 [micro-gram]/g. TCP was highest in the stems and green...
Hormonal and genetic control of leaf and vein development in maize
(University of Missouri--Columbia, 2022)
Grasses (Poaceae) have successfully colonized diverse terrestrial ecosystems and impacted human civilization by producing the bulk of world food supply. The grass leaf is distinct for having a sheathing base and strap-like ...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
of performance could potentially require wider or narrower buffer widths in order to meet certain stormwater management criteria. This method was successfully demonstrated within the LaBarque Creek watershed located southwest of St. Louis, Missouri for three...
Single and multi-object video tracking using local and deep architectures
(University of Missouri--Columbia, 2022)
Moving object tracking is a fundamental computer vision task with a wide variety of real-life applications ranging from surveillance and autonomous systems to biomedical video analysis. A robust, accurate, scalable, and ...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
sampling) on four different ages (0, 3, 7-8, 14-16 yrs) of grassland in east-central Missouri. Efficacy of sampling methods was also examined. A total of 18,743 ants were collected, representing 28 species in 16 genera. Ants were most abundant in older ages...
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 ...
Enhancing efficacy, performance, and applicability of additive food manufacturing
(University of Missouri--Columbia, 2021)
changes (e.g., shape morphing, color change) of a 3D-printed product after exposure to a stimulus (e.g., pH change, water, heat). Successful adoption of this novel AM technology needs substantial work in selecting appropriate materials, creating...
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...
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) ...
