In Fall 2020, universities saw extensive transmission of SARS-CoV-2 among their populations, threatening health of the university and surrounding communities, and viability of in-person instruction. Here we report a case study at the University of Illinois at Urbana-Champaign, where a multimodal "SHIELD: Target, Test, and Tell" program, with other non-pharmaceutical interventions, was employed to keep classrooms and laboratories open. The program included epidemiological modeling and surveillance, fast/frequent testing using a novel low-cost and scalable saliva-based RT-qPCR assay for SARS-CoV-2 that bypasses RNA extraction, called covidSHIELD, and digital tools for communication and compliance.

Increased intake, frequency, and dental contact time of carbohydrate-rich foods, sports nutrition products, and acidic carbohydrate-containing sports and energy drinks may contribute to risks of dental erosion, caries, and inflammatory periodontal conditions in the athlete, especially when he or she also exhibits dehydration and poor oral hygiene habits. Examining the athlete before he or she begins participating in a sport allows the dental care provider to determine the patient's existing oral health, hygiene, and susceptibility to risk factors for erosion, caries, and inflammatory periodontal disease.

Such a view arises partly from a recent change in emphasis in wastewater treatment technology, from simply oxidising the organic matter in the waste (i.e.

The data presented here, compares the mass spectral fingerprints of the different fuels as measured by the Aerodyne high resolution time-of-flight aerosol mass spectrometer. There were three sample points, two at the exhaust exit plane with dilution added at different locations and another probe located 10 m downstream.

One such strategy being investigated is the use of alternative fuels in aircraft engines and auxiliary power units (APUs) as a means to diversify fuel supplies and reduce emissions. This paper summarizes the results of a study to characterize the emissions of an APU, a small gas turbine engine, burning conventional Jet A-1, a fully synthetic jet fuel, and other alternative fuels with varying compositions.

The concentration of PAH compounds in the exhaust emissions vary greatly between fuels. Combustion of FSJF produces the greatest total concentration of PAH compounds while combustion of GTL produces the least.

Sixty-five staff working with 22 individuals were interviewed using an inventory of putative setting events. Findings were collated to allow identification of those events reported to be associated with increased and decreased likelihood of challenging behavior.

This article presents information for dental professionals to enhance awareness of emerging issues in women's oral health, with specific emphasis on female athletes. These issues include the prevalence, prediction, and prevention of sports-related traumatic orofacial injuries as well as fads and habits such as tongue piercing, smokeless tobacco, eating disorders, and performance-enhancing drugs.

Staff reports suggested considerable variability in challenging behavior in the presence of different staff and, from day to day, in the presence of the same staff. Variability was greater for stereotyped than for aggressive/destructive behavior, and for more frequent behavior.

This report describes a case of necrotizing sialometaplasia (NS) in a patient diagnosed as having Buerger's disease with secondary Raynaud's phenomenon. The danger of misdiagnosing NS as a malignant lesion is emphasized. Possible causal relationships between the patient's medical condition and the lesion are discussed.

Pyran covalently linked to cyanogen bromide-activated Sepharose has been shown to be an effective affinity matrix for several viral DNA polymerases. Differential salt elution of viral compared with cellular polymerases, as well as substrate elution, suggests the affinity nature for the matrix. Unlike some other affinity systems described, pyran-Sepharose is totally resistant to nuclease digestion and is stable at 4 degrees for several months.
