Editing OWL through generated CNL

Abstract. Traditionally, Controlled Natural Languages (CNLs) are de-signed either to avoid ambiguity for human readers, or to facilitate auto-matic semantic analysis, so that texts can be transcoded to a knowledge representation language. CNLs of the second kind have recently been adapted to the requirements of knowledge formation in OWL for the Semantic Web. We suggest in this paper a variant approach based on automatic generation of texts in CNL (as opposed to automatic analy-sis), and argue that this provides the best of both worlds, allowing us to pursue human readability in addition to a precise mapping from texts to a formal language.

Archaeology Beneath the Greens: An Archaeological Assessment of 41KR573, 41KR574, and 41KR575 at the Scott Schreiner Municipal Golf Course in Kerrville, Texas

The 1999 renovations at the Scott Schreiner Municipal Golf Course offer a unique opportunity for both the golfing community and the archaeological researchers involved with prehistoric settlement patterns along tributaries of major rivers in southcentral Texas. For the golfers, an improved course will be available, for archaeological research, a once-in-a-lifetime opportunity to evaluate subsurface deposits along Quinlan Creek in downtown Kerrville is available. Since the golf course was established in 1924, many surface modifications are present. No archaeological investigations have been conducted in the area, however, many artifacts have been recovered by golfers. Through provisions in the Antiquities Code of Texas (Texas Administrative Code, Title 13 Part 2, Chapter 26, Rules of Practice and Procedure), assessments must be done to evaluate the impact on purled deposits during this 1999 renovation procedure. Limited areas were scheduled for- soil removal and potential site destruction. However, excavation of sprinkler trenches to a depth of two feet across the landscape will allow us to evaluate the extent of unknown buried sites along an area of Quinlan Creek that has never before been available for study. During the course of the investigation, nine areas of potential sites were investigated, with three ( 41KR573, 41KR574, and 41KR575) uncovered with intact deposits, and reburied to prevent further destruction. However, due to previous construction activities, the majority of these sites have been destroyed to the extent that renders them inadequate for inclusion as a candidate for a State Archaeological Landmark status

(1964-1973) and Dr. Lynn Babington (interim President in 2017). Records of Fr. McInnes’ administration are instead included in the Papers of Rev. William McInnes, S.J. The nature and amount of material in this collection varies considerably from administration to administration, but typically includes inauguration materials, congratulation certificates, publicity materials, and/or correspondence (notably including letters by and from Rev. John McEleney, S.J. and Rev. James Dolan, S.J, that relate to Fairfield’s founding and early development). The collection also includes records of the 2016 Presidential Search Committee, whose work resulted in the selection of Rev. Jeffrey von Arx.https://digitalcommons.fairfield.edu/findingaids/1016/thumbnail.jp

Efforts to Reduce International Space Station Crew Maintenance Time in the Management of the Extravehicular Mobility Unit Transport Loop Water Quality

The EMU (Extravehicular Mobility Unit) contains a semi-closed-loop re-circulating water circuit (Transport Loop) to absorb heat into a LCVG (Liquid Coolant and Ventilation Garment) worn by the astronaut. A second, single-pass water circuit (Feed-water Loop) provides water to a cooling device (Sublimator) containing porous plates, and that water sublimates through the porous plates to space vacuum. The cooling effect from the sublimation of this water translates to a cooling of the LCVG water that circulates through the Sublimator. The quality of the EMU Transport Loop water is maintained through the use of a water processing kit (ALCLR - Airlock Cooling Loop Remediation) that is used to periodically clean and disinfect the water circuit. Opportunities to reduce crew time associated with ALCLR operations include a detailed review of the historical water quality data for evidence to support an extension to the implementation cycle. Furthermore, an EMU returned after 2-years of use on the ISS (International Space Station) is being used as a test bed to evaluate the results of extended and repeated ALCLR implementation cycles. Finally, design, use and on-orbit location enhancements to the ALCLR kit components are being considered to allow the implementation cycle to occur in parallel with other EMU maintenance and check-out activities, and to extend the life of the ALCLR kit components. These efforts are undertaken to reduce the crew-time and logistics burdens for the EMU, while ensuring the long-term health of the EMU water circuits for a post- Shuttle 6-year service life

Global Gene Expression of Prochlorococcus ecotypes in Response to Changes in Nitrogen Availability

Nitrogen (N) often limits biological productivity in the oceanic gyres where Prochlorococcus is the most abundant photosynthetic organism. The Prochlorococcus community is composed of strains, such as MED4 and MIT9313, that have different N utilization capabilities and that belong to ecotypes with different depth distributions. An interstrain comparison of how Prochlorococcus responds to changes in ambient nitrogen is thus central to understanding its ecology. We quantified changes in MED4 and MIT9313 global mRNA expression, chlorophyll fluorescence, and photosystem II photochemical efficiency (Fv/Fm) along a time series of increasing N starvation. In addition, the global expression of both strains growing in ammonium-replete medium was compared to expression during growth on alternative N sources. There were interstrain similarities in N regulation such as the activation of a putative NtcA regulon during N stress. There were also important differences between the strains such as in the expression patterns of carbon metabolism genes, suggesting that the two strains integrate N and C metabolism in fundamentally different ways

Risky Business: Reopening Recreational Sport Facilities During COVID-19

At the onset of COVID-19, sport and fitness administrators shut down facilities to mitigate viral spread. To reopen facilities, safety protocols and policies reflecting risk mitigation strategies were established. This case study adopted the International Standards Organization’s risk management framework to explore strategies for reopening collegiate recreational sport facilities during the pandemic. Document analysis was employed to analyze the reopening plans of four collegiate recreation departments across North America. The reopening plans focused on the risk assessment and treatment process and used a phased approach, with strategies moving from risk avoidance to risk reduction and transfer. Common risk management strategies across facility areas included social distancing, reduced programming/services, and increased sanitization. However, notable differences were found based on risk unique to distinct facility areas. Implications for practice include use of a customized facility inspection checklist, adherence to new industry safety standards, and clear communication with stakeholders

Failure Analysis Results and Corrective Actions Implemented for the EMU 3011 Water in the Helmet Mishap

During EVA (Extravehicular Activity) No. 23 aboard the ISS (International Space Station) on 07/16/2013 water entered the EMU (Extravehicular Mobility Unit) helmet resulting in the termination of the EVA (Extravehicular Activity) approximately 1-hour after it began. It was estimated that 1.5-L of water had migrated up the ventilation loop into the helmet, adversely impacting the astronauts hearing, vision and verbal communication. Subsequent on-board testing and ground-based TT and E (Test, Tear-down and Evaluation) of the affected EMU hardware components led to the determination that the proximate cause of the mishap was blockage of all water separator drum holes with a mixture of silica and silicates. The blockages caused a failure of the water separator function which resulted in EMU cooling water spilling into the ventilation loop, around the circulating fan, and ultimately pushing into the helmet. The root cause of the failure was determined to be ground-processing short-comings of the ALCLR (Airlock Cooling Loop Recovery) Ion Filter Beds which led to various levels of contaminants being introduced into the Filters before they left the ground. Those contaminants were thereafter introduced into the EMU hardware on-orbit during ALCLR scrubbing operations. This paper summarizes the failure analysis results along with identified process, hardware and operational corrective actions that were implemented as a result of findings from this investigation

CCD detector performance for NOAO's wide-field MOSAIC cameras

In July of 1998 the National Optical Astronomy Observatories (NOAO) successfully upgraded MOSAIC 1, an 8192 by 8192 pixel array using eight Scientific Imaging Technologies, Inc. (SITe) St-002A thinned backside 2k by 4k charge coupled devices (CCDs). In July of 1999 MOSAIC II, a clone of MOSAIC I was commissioned also using eight SITe ST-002A CCDs. Additionally in December of 1998 NOAO implemented Mini- MOSAIC a 4096 by 4096 pixel array using two SITe ST-002A thinned CCDs. This report will discuss the performance, characterization and capabilities of the three wide field imagers now in operation at NOAO's Kitt Peak Observatory, Cerro Tololo Inter-American Observatory and at the WIYN Consortium 3.5-Meter telescope on Kitt Peak
