    A high number of liquid oxygen and gaseous hydrogen orifices per unit area are provided in an injector head designed to give intimate mixing and more thorough combustion. The injector head comprises a main body portion, a cooperating plate member as a flow chamber for one propellant, a cooperating manifold portion for the second propellant, and an annular end plate for enclosing an annular propellant groove formed around the outer edge of the body. All the openings for one propellant are located at the same angle with respect to a radial plane to permit a short combustion chamber

    Ultrasonic nondestructive materials characterization

    A brief review of ultrasonic wave propagation in solid materials is presented with consideration of the altered behavior in anisotropic and nonlinear elastic materials in comparison with isotropic and linear elastic materials. Some experimental results are described in which ultrasonic velocity and attenuation measurements give insight into materials microstructure and associated mechanical properties. Recent developments with laser beam non-contact generation and detection of ultrasound are presented. The results of several years of experimental measurements using high-power ultrasound are discussed, which provide substantial evidence of the inability of presently accepted theories to fully explain the interaction of ultrasound with solid materials. Finally, a special synchrotron X-ray topographic system is described which affords the possibility of observing direct interaction of ultrasonic waves with the microstructural features of real crystalline solid materials for the first time

    An Analysis of Faith-Based Homeless Social Service Providers in Baton Rouge, Louisiana and their Role in Helping Homeless People

    Get PDF
    In recent years, there has been a strong push on the federal level to support efforts of faith-based organizations, which provide a variety of social services ranging from literacy improvement efforts to homeless prevention. This thesis sheds light on the current efforts by faith-based homeless service providers in the Baton Rouge area, and examines their role in helping the homeless. This thesis uses existing literature and interviews with the director of The Capital Area Alliance for the Homeless as well others involved with homeless programs in Baton Rouge. This thesis also provides data collected by the ServicePoint HMIS (Homeless Management Information System) which gives a clearer picture of which agencies are providing services in Baton Rouge, and the clients served by these agencies. The efforts of these organizations were particularly critical following Hurricane Katrina, and it is vital that those in the policy arena understand the role of these organizations

    AGRICULTURAL COOPERATIVE MANAGERS AND THE BUSINESS ENVIRONMENT

    Get PDF
    Managers of agricultural cooperatives were contacted to determine their knowledge/capabilities and perspectives of the cooperative environment with special emphasis given to the importance of cooperative principles to the operation and success of the business, division of responsibility between management and the board of directors, and business decision making in the areas of financial analysis plus selected scenarios. Managers showed strong adherence to traditional cooperative principles and basic decision areas. Self-assessments were positive and consistent with performance measures. The opportunity exists to improve manager knowledge/capabilities related to cooperative principles, division of responsibility between managers and the board, and financial analysis.board of directors, cooperative principles, cooperatives (agricultural), leadership, management, managers, Agribusiness,

    Acousto-ultrasonic nondestructive evaluation of materials using laser beam generation and detection

    Get PDF
    The acousto-ultrasonic method has proven to be a most interesting technique for nondestructive evaluation of the mechanical properties of a variety of materials. Use of the technique or a modification thereof, has led to correlation of the associated stress wave factor with mechanical properties of both metals and composite materials. The method is applied to the nondestructive evaluation of selected fiber reinforced structural composites. For the first time, conventional piezoelectric transducers were replaced with laser beam ultrasonic generators and detectors. This modification permitted true non-contact acousto-ultrasonic measurements to be made, which yielded new information about the basic mechanisms involved as well as proved the feasibility of making such non-contact measurements on terrestrial and space structures and heat engine components. A state-of-the-art laser based acousto-ultrasonic system, incorporating a compact pulsed laser and a fiber-optic heterodyne interferometer, was delivered to the NASA Lewis Research Center

    Equity -- 1957 Tennessee Survey

    Get PDF
    JURISDICTION: Among what is said\u27 to be the largest number of public laws ever passed by a Tennessee Legislature, the General Assembly passed an act which creates a statutory exception to the doctrine that equity will not enjoin the commission of a crime unless the conduct comes within some recognized head of equity jurisdiction. EQUITABLE REMEDIES: Hall v. Briton was a suit in the chancery court to enjoin defendants, who were complainant\u27s former employees, from selling a product produced with the aid of complainant\u27s trade secret. CONTEMPT: One of the peculiarities of equity is that its decrees frequently consist of in personam orders. The violation of such an order is contempt of court. Contempts are classified as either civil or criminal. PRACTICE: The 1957 General Assembly amended the practice in chancery courts in Tennessee so as to provide that a sworn answer, when required by a bill of discovery or when the oath to the answer is not waived, shall have no more weight or effect in evidence than the deposition of the defendant filing such answer
