Thermophysical properties of dense supercriiicai water with special emphasis on dielectric permittivity are discussed. Phase diagrams and some critical curves of the binary systems H20—H2, H2O—N, H20—02, H20-CH4 and H20-He to 450 °C and 200 MPa are shown. H20-He tas a type I critical curve. A rational equation of state to calculate phase diagrams and critical curves for polar—non polar systems ...

PURPOSE To evaluate the role of corneal epithelium in riboflavin/ultraviolet-A (UVA) mediated corneal collagen cross-linking treatment. METHODS Fifty New Zealand rabbits were divided into 5 groups: UVA treatment with or without corneal epithelium, UVA+riboflavin treatment with or without corneal epithelium, and control without any treatment. All rabbits were sacrificed after irradiation and s...

The activity of chymosin, plasmin, and Lactococcus lactis enzymes (cell envelope proteinase, intracellular peptidases, and glycolytic enzymes) were determined after 5-min exposures to pressures up to 800 MPa. Plasmin was unaffected by any pressure treatment. Chymosin activity was unaffected up to 400 MPa and decreased at 500 to 800 MPa. Fifty percent of control chymosin activity remained after ...

The first quermassintegral of a set C ⊂ Rd is a characteristic of C closely related to its surface area. Quermassintegrals have traditionally been viewed in the context of convex geometry, and their definition relies on a classic theorem in the field, Steiner’s Formula for Parallel Bodies. Nonetheless, the concept can apply to any set, and in this paper we look at how the properties of quermass...

Pupylation is a bacterial post-translational modification of target proteins on lysine residues with prokaryotic ubiquitin-like protein Pup. Pup-tagged substrates are recognized by a proteasome-interacting ATPase termed Mpa in Mycobacterium tuberculosis. Mpa unfolds pupylated substrates and threads them into the proteasome core particle for degradation. Interestingly, Mpa itself is also a pupyl...
