Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn

Graduate Theses and Dissertations

The Center for Disease Control and Prevention (CDC) suggests that adolescents and children, both male and female, are failing to meet the daily fruit and vegetable consumption requirements (Kim et al., 2011; Upton et al., 2012; Harris et al., 2012). Other studies have shown that with increased exposure and availability of produce, students (K-5) tend to consume more fruits and vegetables (Cullen et al., 2009; Evans et al., 2012). The purpose of this study is to identify whether Northwest Arkansas eleventh grade high school students possess experience and knowledge of local produce and agriculture. Out of 1054 students enrolled at …

Measuring The Energy Required To Dry Rice In Commercial Rice Dryers, Maria Alejandra Billiris

Graduate Theses and Dissertations

The objective of this research was to quantify and assess the energy use and efficiency of commercial cross-flow dryers when drying rice using a range of drying and ambient conditions. First, equations that predict the theoretical energy required to dry rice from any given initial moisture content to a desired final moisture content were developed for several rice cultivars using a semi-theoretical approach to obtain a basis for comparison to calculate energy efficiency. Theoretical energy requirements, expressed as the energy required per unit mass of water removed, increased exponentially as initial moisture content decreased. Additionally, medium-grains required more energy to …

Agricultural Development In The Northern Savannah Of Ghana, Tara N. Wood

Doctor of Plant Health Program: Dissertations and Student Research

Since declaring independence in 1957, the Republic of Ghana has become a stable constitutional democracy. Ghana’s economy has grown substantially over the past decade, yet remains primarily agrarian, accounting for 50% of the total employment and 25% of the country’s Gross Domestic Product. Smallholder rain-fed farming using rudimentary technologies dominates the agricultural sector accounting for 80% of total agricultural production. Approximately 90% of smallholder farms are less than two hectares in size, and produce a diversity of crops. The major crops cultivated in Ghana include numerous cereal, root and tuber, leguminous, fruit, vegetable and industrial crops. Maize is the most …

Assessing The Importance Of Sequencing Laboratory Welding Practicums, Malcolm Riley Rose

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine if having fewer operator-controlled variables during welding will improve secondary students' ability to meet weld quality standards for an AWS 1F test. Two different welding processes, Gas Metal Arc Welding and Shielded Metal Arc welding, were used in the research. The population of this study (N = 71), participants were randomly assigned into one of four treatment groups. The study was conducted over six class periods. Participants completed a welding pretest, taught safety procedures followed by welding instruction of both GMAW and SMAW process. Practice sessions were given for each welding …

Effects Of Integrating Mathematical Concepts Into An Animal Science Curriculum, Andrea Rae Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nationwide, mathematical scores have been a topic of concern among elementary and secondary educators for many years. Teaching contextualized math has been found to be effective and includes providing a direct application to real-life scenarios rather than teaching linear equations and algebraic principles outside of their application.

A study was conducted measuring the effects of integrating mathematical skills in an animal science curriculum. All students were taught a unit of instruction about animal nutrition and feeding. The control group received a typical nutrition unit and the treatment group received the same unit of instruction with the addition of mathematical skill …

Studies On Nitrogen And Silicon Deficiency In Microalgal Lipid Production, Curtis Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microalgae are single celled plants that inhabit aquatic and terrestrial environments across the planet. Many species are oleaginous, which means they are capable of producing oils, similar to many higher plants we are familiar with like canola, safflower and coconut. Different from higher plants, however, algae have simple structures that allow them to grow at very high rates. Due to these characteristics—oil production and rapid growth rates—algae are considered a promising future source of oil. Algal oils could be useful for production of food for people, feed for animals, biodiesel, detergents, and many other applications.

Algae have not been heavily …

Evidence Of Agrarian Urbanism: Land Use Preferences Of Residents Living On Small Acreage Farms Or Large Lots With Animal Rights In Cache Valley, Utah, Laurie B. Hurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Until the last half century, land development patterns in the Intermountain West were designed after the Mormon settlement pattern. With its gridiron streets and in-town farmsteads, this pattern gave families the opportunity to grow crops and raise a few animals on their one acre or less in town, with the added advantage of having a social life. In many places over the last century, cities have grown, small farms have dwindled, and large farms have been pushed to the fringe. However, in the Intermountain West the agrarian tradition continues with a number of families who grow gardens and raise animals …

Predicting Groundwater Trading Participation In The Upper Republican River Natural Resource District, Elizabeth M. Juchems

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The goal of this thesis is to predict participation in groundwater trading and the directions of trades among participants. Specifically, the paper considers both formal and informal trading of groundwater used for crop irrigation purposes and attempts to identify those characteristics that predict the probability of trade participation and whether an individual is a buyer or seller of groundwater rights. While the public benefits from efficient use of groundwater include adequate stream flow in hydrologically connected areas and future use of groundwater supplies, there are significant private benefits to landowners especially in water-short areas. Groundwater trading can help move water …

Light Level Does Not Alter Ethylene Sensitivity In Radish Or Pea, Joseph F. Romagnano, Bruce Bugbee

Plants, Soils, and Climate Faculty Publications

Ethylene accumulation occurs in many plant growth environments. In some instances, low photosynthetic photon flux (PPF) is also a stress factor. Ethylene helps regulate the shade-avoidance mechanism and synthesis rates can be altered by light. We thus hypothesized that ethylene sensitivity in whole plants may be altered in low light. Radish (Raphanus sativus) and pea (Pisum sativum) plants were selected as models due to their rapid growth, use in previous studies and difference in growth habit. We first characterized radish and pea sensitivity to ethylene. Radish vegetation was less sensitive to ethylene than pea vegetation. Pea reproductive yield was highly …

Effects Of Sow, Boar, And Semen Traits On Sow Reproduction, Sungwon Park

Department of Animal Science: Dissertations, Theses, and Student Research

The objective was to estimate the effect of traits recorded in females and in boars and their semen on farrowing rate (FR), total number (TB) and number of stillborn pigs (SB) at birth. Results of 20,569 inseminations in 4,468 sows on 4 farms with semen from 856 boars in 2 AI centers were analyzed. Records on sows included farm, dline parity and brdeeding interval (Brdint). Records on boars included number of days rest between collections, and 26 characteristics (e.g., volume, sperm concentration, motility, abnormal heads and tails plus 16 traits that described velocity and path of sperm cell movement). At …
