Study of blade aspect ratio on a compressor front stage aerodynamic and mechanical design report

A single stage compressor was designed with the intent of demonstrating that, for a tip speed and hub-tip ratio typical of an advanced core compressor front stage, the use of low aspect ratio can permit high levels of blade loading to be achieved at an acceptable level of efficiency. The design pressure ratio is 1.8 at an adiabatic efficiency of 88.5 percent. Both rotor and stator have multiple-circular-arc airfoil sections. Variable IGV and stator vanes permit low speed matching adjustments. The design incorporates an inlet duct representative of an engine transition duct between fan and high pressure compressor

Towards a contextual approach to the place–homeless survival nexus: An exploratory case study of Los Angeles County

The characteristics of the immediate locale greatly affect the ability of homeless people to adapt to life on the street and in shelters, with different types of places nurturing different circumstances for survival. Current conceptualizations of the place–survival nexus are too narrow, relying on small-scale, intensive studies of particular places that are known to sustain homeless survival while ignoring more suburban and exurban locales, as well as failing to set these places of survival within the larger socio-economic spaces of the metropolitan area. Further, the literature is heavily qualitative, lacking any kind of ‘‘big picture” quantitative assessment of the nexus. In response, we contribute to the place–survival nexus literature by developing a typology of space for homeless survival and then use interview data to examine the variation in survival strategies across three types of urban space in Los Angeles County. Our results speak to how our innovative and exploratory approach enabled a broader, more extensive and variegated understanding of place–survival among homeless people than previous studie

Review of \u3ci\u3eThe Red Corner: The Rise and Fall of Communism in Northeastern Montana\u3c/i\u3e by Verlaine Stoner McDonald

It\u27s not often that such names as Stalin, Lenin, and Trotsky figure centrally in works dealing with Montana history. But that\u27s the case with Verlaine Stoner McDonald\u27s The Red Corner: The Rise and Fall of Communism in Northeastern Montana. McDonald\u27s history deals with a little-known but fascinating chapter in Montana, and western, history the 1920s electoral takeover of the local government of Sheridan County, Montana, by Communist Party members. As McDonald shows, Sheridan County, an agrarian territory of 10,000 persons in the extreme northeastern corner of the state, proved fertile territory for a variety of leftist political movements, including Bryanite populism, the Non-Partisan League, and, for a brief period, Communism

A Comparison of Qualities Desired in Academic Teachers, Physical Education Teachers, and Athletic Coaches in the Senior High Schools of Utah

The state has ordered the establishment of schools for the education of all the children in the state. Each child is entitled to as thorough an education as the community can afford, and this education can be attained only when the teachers selected are the best possible to obtain with the money available

State Wage Collection Laws: Supplementing the Bankruptcy Act

The general problem to be considered here is that of the employer\u27s insolvency and consequent inability to pay wages which have already been earned. More specifically this comment examines the various types of state legislation designed to assist employees in the collection of these earned but unpaid wages, with primary consideration directed to those statutes which enable the employee to circumvent the limitations of the federal Bankruptcy Act. State wage priority statutes are therefore not included, nor are general creditor collection devices, criminal sanctions against non-payment of wages, and laws authorizing the assignment of wage claims to an administrative agency for collection. The Bankruptcy Act provides one method of collecting unpaid wages, but this remedy is frequently inadequate from the employee\u27s standpoint because of the limitations imposed by the act. These limitations, though necessary for the protection of other classes of creditors, can, in many cases, mean the loss of earned wages if the employee has no remedy other than his claim in the bankruptcy proceedings. The major limitation is the size of the distributable bankruptcy estate. Wage claims, like the claims of other unsecured creditors, can be paid only from assets remaining after secured creditors and lienors have realized on their security. If the employer\u27s property was heavily mortgaged or subject to large tax liens there may be nothing left for unsecured creditors
