    Subsurface Fluid Flow Through the Mississippian Section of North-Central Oklahoma

    This study consisted of using drill stem tests, seismic amplitude data, and well logs to create the parameters needed to construct a groundwater flow model for a portion of Osage County. At the start, a potentiometric map of Osage County, Oklahoma was generated to use as a basis for the initial hydraulic heads and the constant heads in the model. Next, three seismic amplitude images were produced in a seismic interpretation program, OpenDtect, to base the hydraulic conductivity values on. In addition, utilizing Gamma Ray on 12 separate wells east-west across the county, a structural cross-section was created within Petra. Last, all the parameters produced from the previous steps were input into Modflow to create three separate flow models, one being the calibrated model and the other two being the sensitivity analysis models. The final results establish a reliable method to produce the data parameters needed to successfully create a spatially larger model to accurately describe this systems controls on porosity and permeability and hence, the reservoir flow capabilities and quantities

    In order to receive the benefits of telecommuting while preventing a loss in social aspects, the proposed project is a new type of work environment that will be a combination of home and office. A place that provides the necessary technologies that are needed to be a telecommuter. A place that is away from the office and home but still holds the social aspects of an office and comfort of home. An alternate office, a telecommuting hub that contains flexible office space for long term use, temporary use, or day to day use for different businesses and organizations, assisted by the social interaction with nature in an urban environment

    Upper Extremity Joint Mobilization

    Get PDF
    Musculoskeletal injuries are one of the most costly nonfatal pathologies in the United States. Eighty to 90% of persons afflicted with musculoskeletal dysfunctions will require a treatment other than surgery. Manual therapy is a system of techniques which may be used to ease the pain and dysfunction with which these patients present. The purpose of this paper and the accompanying video tape, is to provide the physical therapy student with a source to aid their study of upper extremity joint mobilization. The paper presents a brief history of manual therapy, beginning in ancient Thailand and Egypt and ending with the current joint mobilization education offered to physical therapy students. The basic principles of joint mobilization are explained, followed by a description of the indications for mobilization and the physiologic explanations for these indications. The specific mobilization techniques for selected joints of the upper extremity are explained in detail including a brief description of the anatomy of each joint, the purpose of the mobilization, the patient\u27s position, mobilizing and stabilizing forces and specific instructions for direction of mobilizing force

    Kentucky Law Survey: Environmental Law

    Get PDF
    Under the rubric of environmental law, this Survey addresses three separate topics: air quality control, water conservation and development, and zoning. In the exploration of these three topics, relevant decisions from the Kentucky courts and the Kentucky Department for Natural Resources and Environmental Protection, as well as opinions from the Kentucky Attorney General, are analyzed

    Distribution of Fish Within Headwater Riffles of the Illinois River System, Washington County, Arkansas

    Quantitative sampling of fish was performed in five headwater riffles of the Illinois River System, Washington County, Arkansas during low flow conditions. This study revealed differing fish species composition, biomass and feeding guild segregation between head and tail riffle reaches in 1st through 3rd order. Thirty species representing 10 families were identified. Of this number, darters (Percidae), sculpins (Cottidae), madtoms (Ictaluridae), and central stonerollers (Campostoma anomalum) (Cyprinidae) comprised 67 to 98 percent of riffle head populations. Fish biomass was greater for riffle head areas (0.58-6.6/0.28-2.0 g/m2 ) within sectivores and herbivores dominating. Total fish numbers decreased from riffleheads to tails, while number of species increased. Dominant fish groups in tail areas were minnows (Cyprinidae), darters (Percidae), and sunfishes (Centrarchidae). Feeding guild fish groups in tail areas were predominately insectivore and insectivore-piscivore. Stomach analysis of Cottus carolinae, the dominant headwater riffle predator, indicated selective feeding of macrobenthic invertebrates and fish based on size class. Abundance of herbivore and insectivore fishes in riffles, particularly head reaches, suggests a correlation with positive rheotaxic behavior, microhabitat preference or abundance of macrobenthic invertebrate populations

    The Relationship Between the Attitudes of Directors and Instructors and Student Ratings in Remedial and Developmental Studies in Tennessee\u27s Community Colleges

    The purpose of this study was to determine if a relationship existed between the attitudes of remedial and developmental directors and instructors and student ratings. A population of 230 full-time directors and instructors and 3,269 remedial students were surveyed in the Fall of 1990. The return rate was 95% for the directors and instructors with the student rate dependent upon instructors administering the instruments. Two instruments were developed--one to measure the attitudes of directors and instructors and one for student ratings of instructors. Seven null hypotheses were formulated; 5 were retained and 2 rejected, at the.05 level of significance. Factor analysis identified four student factors and six director and instructor factors. The Pearson r was used to test for relationships in hypotheses 1 through 4, with 24 possible correlations on each hypothesis. The t-test was used to test for differences in hypotheses 5 through 7. Even though findings revealed a low percentage of correlations, significant relationships were found on several factors. A relationship existed between student ratings and instructor willingness to provide extra assistance, and demonstrating a nurturing, caring concern for students. Students and instructors viewed a sense of \u27belongingness\u27 and being an integral part of the college environment as an important factor. Directors and instructors who held strong, egalitarian philosophies believed in open door policies. A difference did not exist between student ratings of faculty who taught remedial and developmental courses only and fully-integrated faculty. A significant difference was found in student ratings of instructors based on age. Differences were noted in the areas of instructor concern, course value, and classroom adaptations among students older than 24
