A semi-empirical method of absorption correction
TLDR
An extension of Furnas's method is described in this paper, where the variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level.Abstract:
An extension of Furnas's method is described. The variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level. Transmission coefficients for any general reflexion hkl are then given approximately by T(hkl) = [T(ϕinc) + T(ϕret)]/2 where ϕinc and ϕret are the azimuthal angles of the incident and reflected beams. Equations are derived for (ϕinc and ϕret and the accuracy of the method is discussed.read more

Evidence for the bilobal nature of diferric rabbit plasma transferrin
TL;DR: Initial studies of the X-ray structure determination of diferric rabbit plasma transferrin have led to a 6-Å resolution electron density map, which indicates a doubling of an ancestral structural gene during the phylogenetic development of the protein.

Plocamium hamatum and its monoterpenes: chemical and biological investigations of the tropical marine red alga
TL;DR: The polyhalogenated monoterpene content of six samples of the tropical marine red alga Plocamium hamatum, collected from the southern, central and northern regions of The Great Barrier Reef, Australia, was assessed and indicated 4 to have potent antialgal activity towards Chlorella fusca in an agar diffusion bioassay.

Structure and catalytic activity of phosphine substituted ruthenium carbonyl carboxylates
TL;DR: In this paper, the structures of the [Ru(CO) 2 (μ-OOCCH 3 )L} 2 ] with L = P n Bu 3, P t Bu 3 or P i Pr 3 have been determined and their catalytic activity tested in the hydrogenation of internal and terminal olefins, of the carbonyl double bond and of both free and esterified carboxylic groups.
