    THE WOMEN OF RED CLYDESIDE THE WOMEN OF RED CLYDESIDE: WOMEN MUNITIONS WORKERS IN THE WEST OF SCOTLAND DURING THE FIRST WORLD WAR By MYRA BAILLIE, B.A., M.A. A Thesis Submitted to the School ofGraduate Studies in Partial Fulfilment ofthe Requirements for the Degree Doctor ofPhilosophy McMaster University © Copyright by Myra Baillie, September 2002 DOCTOR OF PHILOSOPHY (2002) McMaster University (History) Hamilton, Ontario TITLE: The Women ofRed Clydeside: Women Munitions Workers in the West ofScotland during the First World War. AUTHOR: Myra Baillie, B.A., M.A. (McMaster University) SUPERVISOR: Professor R.A. Rempel NUMBER OF PAGES: x,320 11 ABSTRACT During World War One, the Clydeside region became one ofthe most important centres ofwar production in Britain. It also had one ofthe most volatile male workforces, earning it the reputation 'Red' Clydeside. Previous historical accounts have focussed on the skilled workers, debating the extent to which they were red-hot revolutionaries or narrow craft conservatives. To date, there has been no study ofthe region's large, capable, hard-working female workforce. This thesis traces the experience ofthe tens ofthousands ofwomen employed in the Clydeside munitions industry, paying particular attention to the working conditions in local factories. This thesis contributes to the long-standing historiographical arguments over the nature ofRed Clydeside by offering a new view ofthe dilution crisis which stands 11t the epicentre ofthe debate. It finds more cooperation between male and female munitions workers than has previously been recognized, and suggests that class confrontation, not craft conservatism, was at the root ofthe deportation ofthe shop steward leaders in March 1916.

    NASA NASA SP-8074 SPACE VEHICLE DESIGN CRITERIA (GUIDANCE AND CONTROL) SPACECRAFT SOLAR CELL ARRAYS MAY 1971 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION c GUIDE TO THE USE OF THIS MONOGRAPH The purpose of this monograph is to organize and present, for effective use in design, the signifi- cant experience and knowledge accumulated in operational programs to date. It reviews and assesses current state-of-the-art design practices, and from them establishes firm guidance for achieving greater consistency in design, increased reliability in the end product, and greater efficiency in the design effort for conventional missions. The monograph is organized into three major sections that are preceded by a brief introduction and complemented by a set of references. The State of the Art, Section 2, reviews and discusses the total design problem, and identifies which1 design elements are involved in successful design. It describes succinctly the current tech- nology pertaining to these elements. When detailed information is required, the best available references are cited. This section serves as a survey of the subject that provides background material and prepares a proper technological base for the Design Criteria and Recommended Practices. The Design Criteria, shown in Section 3, state clearly and briefly what rule, guide, limitation, or standard must be considered for each essential design element to ensure successful design. The Design Criteria can serve effectively as a checklist of rules for the project manager to use in guiding a design or in assessing its adequacy. The Recommended Practices, as shown in Section 4, state how to satisfy each of the criteria.

These analysis and assessment tools are applied to a four-cylinder, spark ignition, naturally aspirated and air-cooled piston-prop aircraft engine in the landing and takeoff (LTO) phases of flight operations. LTO consists of four parts: takeoff, climb out, approach, and taxi. The results of energy analysis indicate that takeoff is a phase requiring high power with a maximum work rate of 111.90 kW. Maximum fuel energy and exergy rates are calculated to be 444.30 kW and 476.51 kW, respectively. The minimum total loss is found in the taxi phase, while maximum energy and exergy efficiency values are 26.76% and 24.95% in the climb out phase, respectively. Based on the results of the cost analysis, the taxi has the maximum exergy destruction cost rate with 23.41 $/h at a fixed production and 2.96 $/h at a fixed fuel.
