Presented here is an in depth comparison of the Octopus dofleini hemocyanin paralogues, designated A and G. The protein sequences coded by these genes are each comprised of seven oxygen-binding units, or functional units (FU-a to FU-g). Each FU is approximately 400 amino acids in length and a linker region...
A short history is given of cathode-ray tubes, from the
earliest laboratory tubes available during the early 1900's through
present day high performance tubes. Special attention is paid to
the development of post-deflection acceleration types especially
band-type PDA tubes and an improvement on that type known as the
helix-type PDA...
A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis
of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted
biaryls can be produced in just three to four steps from commercially available materials
utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will
illustrate the ability of mono...
