Economic Potash Fertilizer Rate Recommendations, Kimberly B. Oliver

Graduate Theses and Dissertations

This thesis is comprised of two studies that estimate profit-maximizing potassium (K) fertilizer application rates for various crops across different time periods. Estimation of profit-maximizing fertilizer-K rate (K*) for both studies considered the initial soil test level of K (STK) and yield response information, as traditional recommendations do, and added crop price and the cost of fertilizer. Profit maximum occurs where the marginal revenue from additional yield is equal to the marginal cost of applying an additional unit of fertilizer-K. The first study calculated K* for corn (Zea mays) and cotton (Gossypium hirsutum) and compared results to previous studies on …

An Assessment Of The Neurovascular Structures Of The Trigeminal Nerve And Their Relationship To Diet In Primates, Caitlin Yoakum

Graduate Theses and Dissertations

The inferior alveolar nerve (IAN) enters the mandible via the mental foramen, supplies nervous sensation to the mandibular teeth as it travels through the mandibular canal, and exits the mandibular foramen to send information to the brain to maintain chewing cycles and protect the teeth from damage. Although bony canals and foramina have been shown to form around soft-tissue structures, there are some examples (e.g., the hypoglossal nerve/canal) where the nervous structures do not comprise most of the canal/foramina space. It is important to know the size of nerves because it has been established that larger nerves convey more information …

Canine Microwear In Relation To Diet In Sumatran Primates And African Great Apes, Putu Pujiantari

Graduate Theses and Dissertations

This thesis considers canine microwear in relation to diet in five Sumatran primates (Pongo abelii, Hylobates lar, Hylobates agilis, Presbytis thomasi, and Macaca fascicularis) and two African great apes (Pan paniscus and Pan troglodytes schweinfurthii) using both microwear texture analysis and microwear feature analysis techniques. Statistical results for texture analysis show that there are significant differences in scale of maximum and heterogeneity. This indicates that some species have large pits on their canine surfaces, having these dominated by deep features at coarse scale yet have a slight microwear heterogeneity. For feature analysis, all variables show statistically significant variation. Variance in …

Semiflexible Oligomers Crystallize Via A Cooperative Phase Transition, Pierre Kawak, Dakota S. Banks, Douglas R. Tree

Faculty Publications

Semicrystalline polymers are ubiquitous, yet despite their fundamental and industrial importance, the theory of homogeneous nucleation from a melt remains a subject of debate. A key component of the controversy is that polymer crystallization is a non-equilibrium process, making it difficult to distinguish between effects that are purely kinetic and those that arise from the underlying thermodynamics. Due to computational cost constraints, simulations of polymer crystallization typically employ non-equilibrium molecular dynamics techniques with large degrees of undercooling that further exacerbate the coupling between thermodynamics and kinetics. In a departure from this approach, in this study, we isolate the near-equilibrium nucleation …

Agents Of Bioshield: The Fda, Emergency Use Authorizations, And Public Trust, Kirstiana Perryman

Georgia Law Review

The SARS-CoV-2 pandemic spurred the U.S. Food & Drug Administration (FDA) to utilize the Emergency Use Authorization (EUA) procedure more than ever before. The pandemic pushed the relatively obscure procedure into public consciousness, making it a frequent topic of discussion and debate. The EUA procedure permits the FDA Commissioner to authorize the introduction of drugs, devices, or biological products into interstate commerce for use in an actual or potential emergency. To issue an authorization, the FDA Commissioner must determine that it is “reasonable to believe,” based on the “totality of the evidence,” that the product “may be effective.” This standard …

The Georgia State-wide Business Court was established in 2019 with limited jurisdiction over narrow categories of commercial disputes. …

The Gig Economy’S Short Reach: An Analysis Of The Scope Of The Federal Arbitration Act’S “Transportation Worker” Exemption, Emina Sadic Herzberger

Georgia Law Review

The Federal Arbitration Act (FAA) governs arbitration agreements in the United States. Section 1 of the FAA provides an exemption from arbitration for “contracts of employment of seamen, railroad employees, or any other class of workers engaged in foreign or interstate commerce.” In a 2001 decision, Circuit City Stores, Inc. v. Adams, the U.S. Supreme Court held that the residual phrase “any other class of workers engaged in foreign or interstate commerce” includes transportation workers. But, such language is ambiguous, and the Supreme Court did not expound upon what it means to be a transportation worker or to be engaged …
