Decellularized allografts offer potential as heart valve substitutes and scaffolds for cell seeding. The effects of decellularization on the quasi-static and time-dependent mechanical behavior of the pulmonary valve leaflet under biaxial loading conditions have not previously been reported in the literature. In the current study, the stress-strain,(More)
Self-assembled monolayers (SAMs) of 1-alkenes on hydrogen-passivated silicon substrates were successfully patterned on the nanometer scale using an atomic force microscope (AFM) probe tip. Nanoshaving experiments on alkyl monolayers formed on H-Si(111) not only demonstrate the flexibility of this technique but also show that patterning with an AFM probe is(More)
A phased approach has been adopted for upgrading the Luggage Point WWTP for nitrogen removal. Luggage Point WWTP (900,000 EP) is the largest plant operated by Brisbane Water. Management actions recommended by the South East Queensland Wastewater Management Strategy require the effluent total nitrogen levels to be reduced to less than 5 mg/L (50th(More)
Two laboratories tested four different brands of alkaline 2% glutaraldehyde sterilants by the Association of Official Analytical Chemists sporicidal test. Each laboratory found survival of Clostridium sporogenes spores on spore-labeled unglazed porcelain penicylinders (cylinders) to vary from test to test, and survival did not always correlate with(More)
On September 23, 1993, the Food and Drug Administration (FDA) published the final monograph and rule for topical antifungal drug products. This monograph specifies the ingredients, concentration, and labeling under which over-the-counter (OTC) topical antifungal drug products may be marketed without further FDA approval. Currently, the nine products tested(More)
The Association of Official Analytical Chemists (AOAC) test for sporicidal activity of disinfectants (966.04) is used in the United States as the legal criteria for classifying a liquid as a chemical sterilant and also as the indicator of the highest level of disinfectant. This qualitative test contains procedures that may cause inaccurate results. A(More)
