Food System Education Among High School Students, Yussra Mt Ebrahim

Honors Theses and Capstones

As the American public school system is currently designed, the average student is likely to graduate high school without ever having received any formal instruction regarding the food system in which he or she takes part as a consumer. Such instruction was not necessary up until the current era of separation between consumers and food production. Through this research project, I sought to demonstrate the effectiveness of a single introductory lesson on the issues confronting the modern American food system, which I taught to two high school biology classrooms. A pre-survey was taken by the high school biology students online …

Utah Air Quality: Pm 2.5, Randy Martin, Roger Coulombe, Roslynn Brain

All Current Publications

Particulate matter two-point-five (PM_2.5) is a tiny suspended particle of air pollution that can penetrate deeply into our lungs and potentially enter the bloodstream. The 2.5 unit means that the particles are smaller than 2.5 micrometers (a micrometer is one millionth of a meter). In Cache Valley and along the Wasatch Front, these tiny particles form and accumulate to unhealthy levels when air is trapped in the bottom of the valley during cold winter days.

Northern Utah Conventional Peach Orchard Costs And Returns, 20 Acres, 2015, Trevor Knudson, Kynda Curtis, Jennifer Reeve, Brent Black

All Current Publications

This publication contains average costs and returns for establishing and maintaining a 20-acre peach orchard in Northern Utah. Unless otherwise indicated, information in this publication is based upon grower surveys and pricing data collected in 2014. The establishment and operating costs are meant to be “representative” of a Utah peach orchard, but should be adjusted where necessary to reflect individual situations. Site selection, peach variety, pest management and other practices will also affect the establishment and operating costs of an orchard and should be considered by the producer.

Regional Variations Of Optimal Sowing Dates Of Maize For The Southwestern U.S., Boksoon Myoung, Seung Hee Kim, Jinwon Kim, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Sowing date (SD) is sensitive to regional climate characteristics; thus, it is critical to systematically examine the effects of SD on crop yields for various temperature regimes. We performed a sensitivity study of SD for maize in the southwestern U.S. using the regionally extended version of the Agricultural Production Systems sIMulator (APSIM) model. The model was run utilizing North American Regional Reanalysis at a 32 km resolution from 1991 to 2011, with an irrigation threshold at 95% of the soil water-holding capacity. Two types of SD optimizations maximizing yield potential (Yp), varying spatially or interannually, revealed that the optimal SD …

Equine Assisted Activities And Therapies: The Measuring Of Equine Temperament, Thecla M. Helmbrecht Howard

Walden Dissertations and Doctoral Studies

The field of equine assisted activities and therapies (EAAT) is growing in popularity as an alternative healing approach. However, there is a paucity of peer-reviewed research on the horses who serve as equal partners in EAAT. The purpose of this quantitative study was to discover the impact of equine-facilitated therapeutic activities on the temperament of horses, and to determine how to select a better human-to-horse therapeutic match when providing EAAT services. The theoretical framework for this research drew from Romanes' theory of animal intelligence, which predicts that temperament would change as a result of prolonged participation in specific work (EAAT …

Genetic Basis Of Variation For Within-Boll Yield Components In Cotton, Imtiaz Ali, Amir Shakeel, Asif Ali, Bushra Sadia

Turkish Journal of Agriculture and Forestry

Cotton productivity on a per-hectare basis is low in Pakistan. As boll is the basis for seed cotton yield, within-boll yield components can potentially serve as the most basic determinants of cotton productivity on a per unit land area basis. Before attempting the improvement of any trait, it is necessary to know the genetic mechanism lying behind its inheritance. The current study aimed to estimate the genetic basis of within-boll yield components in cotton. The research trials were conducted at the research area of the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad, Pakistan. Epistasis was found to …
