Fluid-pressure meter can be calibrated without removal from flow line

The construction of a fluid pressure meter with two inlet ports, flexible diaphragms and a pressure-responsive transducer is described. One port can be connected to the line and the other to a source of standard pressures for calibration

Conversion Calls for Confrontation: Facing the Old to Become New in the Work of James Baldwin

Book Summary: The recognition and study of African American (AA) artists and public intellectuals often include Martin Luther King, Jr., and occasionally Booker T. Washington, W.E.B.DuBois, and Malcolm X. The literary canon also adds Ralph Ellison, Richard White, Langston Hughes, and others such as female writers Zora Neale Hurston, MayaAngelou, and Alice Walker. Yet, the acknowledgement of AA artists and public intellectuals tends to skew the voices and works of those included toward normalized portrayals that fit well within foundational aspects of the American myths reflected in and perpetuated by traditional schooling. Further, while many AA artists and public intellectuals are distorted by mainstream media, public and political characterizations, and the curriculum, several powerful AA voices are simply omitted, ignored, including James Baldwin. This edited volume gathers a collection of essays from a wide range of perspectives that confront Baldwin’s impressive and challenging canon as well as his role as a public intellectual. Contributors also explore Baldwin as a confrontational voice during his life and as an enduring call for justice. [From the Publisher] Chapter Summary: This discussion examines Baldwin\u27s novel, Go Tell It on the Mountain (1953), and his essay collection, No Name in the Street (1972). Baldwin revisits the traditional biblical conversion narrative by challenging how the converted must learn to reconcile with their past, rather than simply turning away from it

Ballpoint probe gives optimum results in ultrasonic testing

Ballpoint-type ultrasonic probe assembly focuses its beam precisely on the bond lines of a composite thin face sheet structure when testing for bond integrity. It can scan in any direction, and eliminate external couplant spray

System for measuring roundness and concentricity of large tanks

Equipment measures the roundness and concentricity of large, massive tanks. The equipment includes a 34-foot rotary table, a variable reluctance displacement transducer, an electronics console, a digital computer, and a 5-foot plotter used for final data display

ECONOMICS OF BEEF COW CULLING AND REPLACEMENT DECISIONS UNDER GENETIC PROGRESS

Beef cow managers annually face the question of which animals to cull from the herd and replace. The results of this decision affect not only current revenues, but, by altering the genetic composition of the herd, also affect the future profitability of the herd. These genetic changes of the herd may, therefore, be represented as a form of endogenous technological progress to the cow calf producer. This article derives general asset replacement criteria for assets undergoing either exogenous or endogenous progress and illustrates their application with a Florida cow herd example.Livestock Production/Industries,

Transonic and supersonic Euler computations of vortex-dominated flow fields about a generic fighter

Flow fields about a generic flighter model were computed using FL057, a 3-D, finite volume Euler code. Computed pressure coefficients, forces, and moments at several Mach numbers (0.6, 0.8, 1.2, 1.4, and 1.6) are compared with wind tunnel data over a wide range of angles of attack in order to determine the applicability of the code for the analysis of fighter configurations. Two configurations were studied, a wing-body and a wing-body-chine. FL057 predicted pressure distributions, forces, and moments well at low angles of attack, at which the flow was fully attached. The FL057 predictions were also accurate for some test conditions once the leading edge vortex became well established. At the subsonic speeds, FL057 predicted vortex breakdown earlier than that seen in the experimental results. Placing the chine on the forebody delayed the onset of bursting and improved the correlation between numerical and experimental data at the subsonic conditions

Formal Contexts, Formal Concept Analysis, and Galois Connections

Formal concept analysis (FCA) is built on a special type of Galois connections called polarities. We present new results in formal concept analysis and in Galois connections by presenting new Galois connection results and then applying these to formal concept analysis. We also approach FCA from the perspective of collections of formal contexts. Usually, when doing FCA, a formal context is fixed. We are interested in comparing formal contexts and asking what criteria should be used when determining when one formal context is better than another formal context. Interestingly, we address this issue by studying sets of polarities.Comment: In Proceedings Festschrift for Dave Schmidt, arXiv:1309.455

Solar residential heating and cooling system development test program

A solar heating and cooling system is described, which was installed in a simulated home at Marshall Space Flight Center. Performance data are provided for the checkout and initial operational phase for key subsystems and for the total system. Valuable information was obtained with regard to operation of a solar cooling system during the first summer of operation. Areas where improvements and modifications are required to optimize such a system are discussed

Creating Social Change in and Through Intercollegiate Sport

The purpose of this paper is to introduce the work included in the special issue: Creating Social Change in and Through Intercollegiate Sport. In doing so, the author develops a multilevel conceptual model, demonstrating how the research included in the special issue addresses the antecedents and outcomes of social change initiatives in intercollegiate sport at the macro (i.e., institutionalized practices, cultural norms), meso (i.e., support of others, compelling narratives, collaborations) and microlevel (i.e., perspective-altering experiences, attitudes toward role of sport) of analysis. In addition, the author suggests ways to overcome barriers and increase the success of future social change initiatives. Based on this collection of scholarship, the author encourages researchers and practitioners to consider the multilevel factors that influence social change and the subsequent outcomes of such actions
