Reference for radiographic film interpreters

Reference of X-ray film images provides examples of weld defects, film quality, stainless steel welded tubing, and acceptable weld conditions. A summary sheet details the discrepancies shown on the film strip. This reference aids in interpreting and evaluating radiographic film of weldments

Estimating reliability by application of matrix representation

Technique based upon matrix representation and matrix collapsing calculates the probability of successfully completing manned missions and of returning the spacecrew safely to earth. This technique provides analytic expressions for each subsystem, making it possible to relate changes in subsystem reliability directly to mission success and crew safety

The total flow concept for geothermal energy conversion

A geothermal development project has been initiated at the Lawrence Livermore Laboratory (LLL) to emphasize development of methods for recovery and conversion of the energy in geothermal deposits of hot brines. Temperatures of these waters vary from 150 C to more than 300 C with dissolved solids content ranging from less than 0.1% to over 25% by weight. Of particular interest are the deposits of high-temperature/high-salinity brines, as well as less saline brines, known to occur in the Salton Trough of California. Development of this resource will depend on resolution of the technical problems of brine handling, scale and precipitation control, and corrosion/erosion resistant systems for efficient conversion of thermal to electrical energy. Research experience to date has shown these problems to be severe. Hence, the LLL program emphasizes development of an entirely different approach called the Total Flow concept

A performative analysis of primary school governance: labour, costs and repair work

Presented in this thesis is a feminist poststructuralist bricolage of primary school governors’ talk, written narrative accounts and documentation. Drawing from Judith Butler’s writings, this thesis de-naturalises performances of school governing, departing from and countering the functionalist and rationalist standpoints that dominate the field. It is argued that the current body of literature fails to recognise the complexity of evoking the school governor; the labour, costs and repair work required to secure and sustain viable subjectivity within the terms of recognition. By inserting a feminist poststructuralist perspective into the field, the unstable boundaries of school governors’ subjectivity are foregrounded. The Butlerian concepts of ‘recognition’ and ‘intelligibility’ were applied to analyse the performative acts of school governance. Analysis drew attention to how the discursive construction of the school governor is constituted and (re)produced through a gendered intelligibility matrix of commitment, challenge and objectivity that create tensions between different subject positions, most significantly maternal subjectivity. Continual maintenance is thus required and temporarily achieved through ‘emotional labour’ and ‘speech censorship’, where the demands and costs attached to securing recognition and coherence become even greater. These conclusions present a far more complex understanding of accountability in school governance; challenging the notion that school governors’ holding of leaders to account is solely linked to the presence or absence of any expert or ‘professional’ knowledge. Drawing on Butler’s writings has inserted an important dimension into the discussion of school governance, highlighting the labour, costs and repair work that maintain school governor viability. This has raised significant questions about the consequences of school governance’s regulatory imperatives and has implications for the culture that governs the scene of recognition. Significantly more effort to make school governing an inclusive space is required if boards are ever going to be truly reflective of the communities they serve

Registration verification of SEA/AR fields

A method of field registration verification for 20 SEA/AR sites for the 1979 crop year is evaluated. Field delineations for the sites were entered into the data base, and their registration verified using single channel gray scale computer printout maps of LANDSAT data taken over the site

Discrimination in Metropolitan Housing Markets: Phase 3 - Native Americans

This paper documents the results of a pilot paired testing program to examine the treatment of Native Americans by real estate agents in rental housing markets in three states and owner-occupied housing markets in one state. The study finds that the level of discrimination experienced by Native Americans in rental markets exceed those experienced by Hispanics, Blacks, and Asian-Americans.

Protective Factors Among Postsecondary Students Enrolled in a First-Generation Program

For generations, researchers have examined attributes that contribute to the adaptability of low socioeconomic youth. Attributes that help one become resilient are known as protective factors. The purpose of this descriptive study was to explore the protective factor(s) that contributed to the enrollment of first-generation, low-socioeconomic status (SES) students at a southern land-grant university. The population consisted of postsecondary students in a First Scholars program during the 2015-2016 academic year. The authors examine the existing literature on the effects of low SES on postsecondary education in order to explore what assists these students in maintaining a steadfast behavior. Recommendations are made for the recruitment of students who display a higher resiliency to be successful at the postsecondary level and for the First Scholars program on how to further enhance the program
