Cooled miniature pressure transducers effective at high temperatures

Miniature pressure transducers in compact water-cooled mounts are placed in hotter and more confined environments than previously possible. It quantitatively measures high frequency total pressure fluctuations resulting from rotating stall in an axial flow engine compressor

Fatigue strength testing employed for evaluation and acceptance of jet-engine instrumentation probes

The fatigue type testing performed on instrumentation rakes and probes intended for use in the air flow passages of jet engines during full scale engine tests is outlined. A discussion of each type of test performed, the results that may be derived and means of inspection is included

On-line calibration of high-response pressure transducers during jet-engine testing

Jet engine testing is reported concerned with the effect of inlet pressure and temperature distortions on engine performance and involves the use of numerous miniature pressure transducers. Despite recent improvements in the manufacture of miniature pressure transducers, they still exhibit sensitivity change and zero-shift with temperature and time. To obtain meaningful data, a calibration system is needed to determine these changes. A system has been developed which provides for computer selection of appropriate reference pressures selected from nine different sources to provide a two- or three-point calibration. Calibrations are made on command, before and sometimes after each data point. A unique no leak matrix valve design is used in the reference pressure system. Zero-shift corrections are measured and the values are automatically inserted into the data reduction program

The International Restitution of Classical Antiquity: Creating Uniformity Within Museum Restitution Policy

This thesis will explore the scope of the restitution debate for Greek and Italian classical antiquities and how it has evolved over the past 70 years. Chapter 1 will focus on the scholarly works of well-known figures within the restitution debate, including John Henry Merryman, James (Jim) Cuno, and Patty Gerstenblith. Their work is crucial in developing the terminology that defines the debate and also for understanding their opinions on both sides of the debate. Chapter 2 will center on claims to cultural property and restitution efforts that have been made at both the international and national level. The three major international conventions, Hague 1954, UNESCO 1970, and UNIDROIT 1995 will be examined. The United States’ 1983 Convention on Cultural Property Implementation Act (CCPIA) that applies to American museums specifically will be explored. Museum associations such as the Alliance of American Museums (AAM), the Museums Association (U.K. only), and the International Council of Museums (ICOM) will all be examined as well. Finally, the individual policies of the Metropolitan Museum of Art (MET) and the British Museum will also be discussed. Chapter 3 will focus on two major restitution case studies, the Euphronios Krater and the Elgin Marbles. The Euphronios Krater, once owned by the MET, and the Elgin Marbles, still in the possession of the British Museum, are two entirely different antiquities with deep histories of illegal ownership history. Lastly, Chapter 4 will provide a policy proposal for the future of restitution policy. By giving more authority to ICOM, binding, international policies for restitution can be imposed through a new membership agreement. All of these chapters help explain the restitution debate throughout recent history with the goal to find a possible solution to the long debate of who “protects” cultural property the most effectively

AUDUBON\u27S PERSPECTIVE ON COYOTES

Audubon has a membership which probably spans all views of coyotes (Canis latrans) Audubon\u27s staff views coyotes as biologically appropriate predators in most of the Southwest. We believe that they can be an asset to a well-managed ranch, but that they can also cause localized depredation which must be answered. Our members value predators, including coyotes, for then- natural role in ecological systems, including their influence on prey species. Many of our members travel broadly and spend money to view wildlife, and consider it a treat to see and hear coyotes
