Picket Dam Storage for Cattle Manure (2002)
(University of Missouri--Columbia. Extension Division, 2002)
Picket-dam facilities have proven useful for storing semisolid manure. Their design allows excess water from rainfall or other sources to drain away so that the material can be handled with conventional equipment.
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...

(University of Missouri--Columbia, 2006)
evaluated an overall emotional intelligence score using the Emotional Quotient inventory; Short form (EQi:S, BarOn, 2002). The time points were fall, spring, and summer over one academic year. Procedures: Two rural school districts were contacted and elected...
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
Pesticides primarily benefit humans in terms of protection of food production, prevention of diseases, and weed control, but also potentially harm people and the environment. Given increasing current interest in human health and environmental...
Studies of ruminant digestion, ecology, and evolution
(University of Missouri--Columbia, 2008)
This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age classes were evaluated. Split...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
Program assessment : industrial hygiene and safety sciences
(University of Missouri--Columbia, 2010)
Program assessment has long been a critical element for academic programs to ensure continuous quality improvement of their programs. More recently, occupational safety, health and environmental programs have embraced assessment by external groups...
The role of household environment on health outcomes for female adolescents in Kenya
(University of Missouri--Columbia, 2007)
; those between the ages of 20 and 24 comprised nearly half (over 47%) of the sample. This study found a strong association between reported illness and environmental factors in the household. Age and marriage were highly significant factors, producing a...
Studies on the physical properties and preservation of the North American pawpaw (Asimina triloba) fruit
(University of Missouri--Columbia, 2023)
regions of the world. The fruit is native to the United States and grows in over 30 states in the United States including Missouri, Indiana, Ohio, Illinois, and parts of Texas. The fruit has remained underutilized and uncommercialized for several centuries...
An attentional theory of issue-carrying capacity
(University of Missouri--Columbia, 2018)
A plethora of research in cognitive and behavioral psychology showed that there are significant differences in the way men and women process political and social information. It has been widely accepted that women show ...
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...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
