Bacteria with temperature optima of 51–54°C and pH optima of 3.5–4.5 were isolated from geothermal soil collected from Mount Erebus, Ross Island, Antarctica. The isolates were enriched on medium designed for the growth of Thermoplasma but the strains found were members of the genus Bacillus. Comparisons with other the…
Reactive element additions may promote the formation of protective oxide scales on high temperature alloys, and improve long term oxidation resistance by limiting the rate of scale growth and inhibiting scale failure processes. Various modifications to transport properties and mechanical behaviour have been proposed t…

RAD is an interactive computer program for radial distribution analysis of X-ray diffraction data from amorphous materials. RAD has been written in Fortran 77 and runs on IBM PC/XT/AT or compatible computers.
Surface tension data can be used for estimating the solubility of polymers in liquids. By determining the apolar and the polar components of the surface tension of polymers and of solvents, the attractive free energy, δG 121, of a polymer (1) in a given solvent (2) can be established. By also taking into account the c…
The fluorescent pseudomonads are classified as a group, one characteristic of which is that they do not accumulate poly-3-hydroxybutyrate (PHB) during nutrient starvation in the presence of excess carbon source. In this paper we show that prototype strains from this subclass, such as Pseudomonas aeruginosa, Pseudomona…
The crystal structure of the complex of the anti-lysozyme HyHEL-10 Fab and hen egg white lysozyme has been determined to a nominal resolution of 3.0 A. The antigenic determinant (epitope) on the lysozyme is discontinuous, consisting of residues from four different regions of the linear sequence. It consists of the exp…
SIR 88 is an integrated package of computer programs for the solution of crystal structures. The package is based on the estimation of one- and two-phase structure seminvariants and three- and four-phase structure invariants according to the theory of representations [Giacovazzo (1977). Acta Cryst. A 33 , 933–944; (19…
The physical problem considered is that of a drop of liquid forming a bridge between two parallel planar plates, where the contact curves between the drop and the planes are not prescribed a priori. It is shown that for sufficiently large volumes, a stable drop must exist, and that no bifurcation can occurwithin the f…

Materials science treats the relations of composition and structure, on the one hand, to properties. On the other hand, the task of materials engineer ing is to design, evaluate, and optimize potential applications of a (new) material. In the last four decades dramatic advances have demonstrated how far our understan…
Osteogenin was purified from bovine bone matrix and its activity monitored by an in vivo bone induction assay. The purification method utilized extraction of the bone-inducing activity with 6 M urea, followed by chromatography on heparin-Sepharose, hydroxyapatite, and Sephacryl S-200. Active fractions were further pur…
The viscosity of a suspension of spherical Brownian particles is determined by Stokesian dynamics as a function of the Péclet number. Several new aspects concerning the theoretical derivation of the direct contribution of the Brownian motion to the bulk stress are given, along with the results obtained from a simulati…

The binding of Congo red to several purified amyloid-like peptides having a beta-pleated sheet conformation was quantitatively examined. Congo red binds preferentially to the beta-pleated sheet conformation of both insulin fibrils and poly-L-lysine. Congo red does not bind nearly so well to poly-L-serine or polyglycin…
