The Ancient Past: Learning a Language to Connect Materials with Users
Archives of the ancient world evince the longevity of our
shared interests in preserving and documenting the
culture, government, and knowledge of civilization.
Whether studied by global travelers, classical archaeologists
and historians, or filmmakers and television producers,
archival materials from the ancient Mediterranean are
contributing to collective memory, educational programming,
and institutional collections.
In this vein, the Program in Aegean Scripts and Prehistory
(PASP) in the Department of Classics at The University of
Texas at Austin fosters research and scholarship on the use of
writing in Minoan Crete, Mycenaean Greece, and the island
of Cyprus during the Bronze Age. There is a special focus on
two early writing systems: Linear A and Cretan hieroglyphics
(1900–1450 BCE) and Linear B (1400–1200 BCE).
The program boasts an international base of researchers and
users, and in recent years, staff have improved collection
accessibility by reconfiguring physical spaces, advancing
digitization projects, preserving endangered email accounts,
and expanding the scope of collections to provide better
access to these important materials.Classic
Final S020 Skylab experiment report
After the loss of the meteroid shield required using the solar scientific airlock to erect the sun shade, methods were improvised to operate the S020 experiment on EVA's. Almost no data was obtained in the wavelength range 10 to 110 A. From 110 to 280 A the spectra were 10 to 100 time less intense than expected. A probable cause in loss of instrument sensitivity is the contamination of the filters by the spacecraft coolant. A list of observed lines in presented. Although less data was obtained than expected, several lines not previously observed were recorded; and the spectra serve to confirm many very faintly observed weak lines recorded from sounding rockets by other experiments
Space shuttle orbiter test flight series
The proposed studies on the space shuttle orbiter test taxi runs and captive flight tests were set forth. The orbiter test flights, the approach and landing tests (ALT), and the ground vibration tests were cited. Free flight plans, the space shuttle ALT crews, and 747 carrier aircraft crew were considered
Near-field antenna testing using the Hewlett Packard 8510 automated network analyzer
Near-field antenna measurements were made using a Hewlett-Packard 8510 automated network analyzer. This system features measurement sensitivity better than -90 dBm, at measurement speeds of one data point per millisecond in the fast data acquisition mode. The system was configured using external, even harmonic mixers and a fiber optic distributed local oscillator signal. Additionally, the time domain capability of the HP8510, made it possible to generate far-field diagnostic results immediately after data acquisition without the use of an external computer
No ifs, ands or butts: Illinois casinos lost revenue after smoking banned

Casino revenue and the Illinois smoking ban
Smoking was banned in all Illinois casinos in January 2008. We explore the effects that the smoking ban has had on Illinois casino revenue and attendance. Our empirical methodology extends and enhances that of previous literature in that we observe a natural experiment in comparing the performance of Illinois casinos with out-of-state casinos (no smoking ban) that share a market with Illinois casinos. Estimates suggest that revenue and admissions at Illinois casinos declined by more than 20 percent (200 million.Gambling industry ; Tobacco industry ; Illinois
