    Merged with duplicate record (10026.1/2025) on 03.01.2017 by CS (TIS)This is a digitised version of a thesis that was deposited in the University Library. If you are the author please contact PEARL Admin ([email protected]) to discuss options.The area investigated for this thesis is the western end of the Iveragh Peninsula, Co. Kerry, southwest Ireland. The rocks in the area are predominantly of Old Red Sandstone facies, totalling over 6600m in thickness, and were deposited near the northern fault-bounded margin of the extensive half-graben feature known as the Munster Basin. Towards the end of the basin's history, continental conditions were replaced by marginal marine as the sea transgressed into the area from the south. The objectives of the study are to provide a description of the poorly known sedimentary facies from this part of the basin, to interpret these in terms of processes and environments of deposition, and to review and clarify long-standing issues arising from the poorly known age and correlative significance of the lower parts of the Iveragh succession. Mapping and detailed logging of selected sections have been carried out. A number of facies types are identified, and interpretation of these in the light of palaeocurrent and other evidence suggests a terminal-fan model for sediment deposition. Sediment transport was largely by unconfined episodic sheet floods , with transport consistently from the north. Calcrete formation, although limited, suggests a semi-arid climatic setting. Fish fossils and plant miospores date the basin-fill as Upper Devonian in age, possibly just extending down into latest Middle Devonian. Miospore assemblages allow regional correlation with other areas in the Munster Basin. Minor igneous intrusive and extrusive rocks in the area have been mapped and described, and consist of contemporaneous acid pyroclastics as well as late or early post-Devonian intrusives. One dyke in the area is considerably younger, probably Tertiary in age. A thick tuff bed, the Keel Tuff Bed, is traced over part of the area, and may have regional correlative significance

    Mordecai F. Ham: Southern Fundamentalist

    Get PDF
    Mordecai Fowler Ham, Jr. (1877-1961), a Kentucky bred, Southern Baptist evangelist, was an active participant in both the prohibition and fundamentalist movements. His career was characterized by disagreement and conflict due to Ham\u27s defiance toward anyone who did not profess his style of Christianity. A true product of the period in which he lived, Ham fought modernism and evolution zealously. He also preached against the use and sale of alcohol and dared liquor supporters to challenge his position. He was convinced as well that Jews, blacks, and Haman Catholics posed a potential threat to Christian America, and he monitored their activities cautiously for the majority of his sixty-year ministry. Ultimately ham\u27s Southern audiences grew tired of the evangelist\u27s allegations and stopped listening to him. Ham, however, continued to preach against his opposition until his death in 1961

    Collegiate Experience: A Literature and Phenomenological Study on Experiential Learning in University Education

    Get PDF
    This research project explored the effectiveness of experiential learning programs within college education for producing long term, deeper understandings of the subjects being taught. To analyze the effects of experiential learning on students, a literature review and synthesis of previous experiential learning studies and research was conducted. First, research was done into studies and publications that discuss educational concepts and theories regarding learning through experience, including Experiential Learning Theory itself. Next, studies of experiential learning programs and courses within academic institutions were analyzed to determine how experiential learning has been applied in the past in a variety of disciplines and how it has affected students. And lastly, studies and literature on how these programs have been applied in professional settings and how students whose educations included experiential learning opportunities perform professionally were compiled to provide a broader view of the impact experiential learning has on students. Along with the literature review, this project included phenomenological research into experiential learning at Embry-Riddle Aeronautical University, specifically within the David O’Malley College of Business’ Professional Consulting program, where students participate in an experiential learning course. Findings from both the literature review and phenomenological research were synthesized, and showed that experiential learning programs provide students with better understandings of the concepts explored and the deeper methods and theories behind the surface-level topics, which resulted in students holding onto the knowledge for longer and being able to better apply it in a wider range of scenarios, outside of those specifically explored during their education

    Response of giant ragweed, jimsonweed, common lambsquarters, tall morningglory, and velvetleaf in soybeans to various overtop postemergence herbicides

    Many broadleaf weeds in soybeans [Glycine max (L.)] are not adequate-ly controlled by currently available preemergence herbicides. Recent studies have shown that several postemergence herbicides, such as bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2,2-dioxide], chloroxuron [3-[p-(p-chlorophenoxy) phenyl]-1,1-dimethylurea], dinoseb [2-sec-butyl- 4,6-dinitrophenol] plus naptalam [N-1-naphthylphthalamic acid], 2,4-DB [4- (2,4-dichlorophenoxy) butyric acid], and RH-6201 [sodium 5-2-chloro-4- (trifluoromethyl)-phenoxy-2-nitrobenzoate], can be applied overtop of soybeans without causing severe injury. The objective of this 1977 study was to determine the efficacy of these herbicides, when applied at different stages of growth, for control of tall morningglory [Ipomoea purpurea (L.) Roth], jimsonweed [Datura stramonium (L.)], giant ragweed [Ambrosia trifida (L.)], common lambsquarters [Chenopodium album (L.)], and velvetleaf [Abutilon theophrasti (Medic.)] in soybeans. The experiment was conducted on sites where natural infestations of jimsonweed, tall morningglory, common lambsquarters, and velvetleaf occurred. The giant ragweed experiment was seeded. Alachlor [2,-chloro- 2\u27,6\u27-diethyl-N-(methoxymethyl) acetanilide] was applied as a preemergence herbicide over each experimental area to control annual grasses. Herbicides were applied overtop of soybeans in late spring and early summer of 1977 as the weeds reached various plant heights, i.e., 3 to 5, 10 to 15, 20 to 25, and 38+ cm. tall. Bentazon effectively controlled giant ragweed less than 15 cm, tall, common lambsquarters less than 10 cm. tall, and velvetleaf less than 30 cm. tall. It did not control tall morningglory but controlled jimsonweed through the 38+ cm. height. Chloroxuron effectively controlled common lambsquarters less than 10 cm. tall, velvetleaf less than 15 cm. tall, jimsonweed less than 15 cm. tall, and tall morningglory less than 5 cm. long. Dinoseb plus naptalam effectively controlled giant ragweed less than 15 cm. tall, tall morningglory less than 5 cm. long, velvetleaf less than 15 cm. tall, and jimsonweed at all stages of growth. It did not control common lambsquarters. Giant ragweed less than 30 cm. tall was effectively controlled by 2,4-DB. Common lambsquarters (less than 5 cm. tall) and velvetleaf (less than 15 cm. tall) were also controlled by 2,4-DB. Jimsonweed and tall morningglory (Spring Hill experiment only) were susceptible to 2,4-DB at all stages of growth used in this study, and tall morningglory (Knoxville experiment only) less than 15 cm. in length was also susceptible. The herbicide RH-6201 effectively controlled giant ragweed less than 15 cm. tall, common lambsquarters less than 5 cm. tall, tall morningglory less than 5 cm. in length, velvetleaf less than 5 cm. tall and jimsonweed at all stages of growth

    Fast Super-Resolution Using an Adaptive Wiener Filter with Robustness to Local Motion

    Get PDF
    We present a new adaptive Wiener filter (AWF) super-resolution (SR) algorithm that employs a global background motion model but is also robust to limited local motion. The AWF relies on registration to populate a common high resolution (HR) grid with samples from several frames. A weighted sum of local samples is then used to perform nonuniform interpolation and image restoration simultaneously. To achieve accurate subpixel registration, we employ a global background motion model with relatively few parameters that can be estimated accurately. However, local motion may be present that includes moving objects, motion parallax, or other deviations from the background motion model. In our proposed robust approach, pixels from frames other than the reference that are inconsistent with the background motion model are detected and excluded from populating the HR grid. Here we propose and compare several local motion detection algorithms. We also propose a modified multiscale background registration method that incorporates pixel selection at each scale to minimize the impact of local motion. We demonstrate the efficacy of the new robust SR methods using several datasets, including airborne infrared data with moving vehicles and a ground resolution pattern for objective resolution analysis
