The circular wave basin provides a means of physically modeling the nearshore
without the typical problems associated with end walls. Three different coastal
processes were examined to demonstrate the use of a spiral wavemaker in a circular
wave basin. These were longshore currents, shear waves, and groin circulation. A
beach...
A simple matrix method for the analysis of protein circular dichroism (CD) spectra is presented and used to compute the secondary structure of globular proteins in their native and denatured states. The method uses singular value decomposition and generalized inverse algorithms, and a basis set of CD spectra for proteins...
The association of hyaluronic acid (HA) into a double stranded
structure has been investigated by circular dichroism (CD)
spectroscopy into the vacuum ultraviolet region. The CD of HA changes
dramatically, monitoring a cooperative transition as the dielectric
constant of an aqueous solution is reduced by adding organic solvents.
This structural...

The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...
Tan spot of wheat is an economically significant disease caused by the fungal pathogen, Pyrenophora tritici-repentis. Certain races of the fungus secrete Ptr ToxA (ToxA), a 13.2 kDa proteinaceous host-selective toxin that is responsible and sufficient to cause disease in susceptible wheat varieties. Disease symptoms develop only when the ToxA...
High hydrostatic pressure processing (HPP) is a nonthermal process in which foods are subjected to pressures in the range of 100-700 MPa at room temperatures or higher. HPP is effective in reducing microbial counts and enzyme activity. The ability of HPP to modify the functional properties of proteins has become...
