The Raman spectra of both the NAD-pyruvate and the pyridine aldehyde adenine dinucleotide (PAAD)-pyruvate bound to pig heart, pig muscle, and Bacillus stearothermophilus lactate dehydrogenases were measured and are nearly the same, which is consistent with the conserved shell of residues surrounding the active-site ca…
This paper summarises the properties of archiral and chiral liquid crystalline (LC) elastomers, the latter of which have found interest due to their piezoelectric properties. In addition the formation of new LC elastomers by a radical polymerization of acrylate groups covalently linked to LC polymers was investigated.…

Summary The sorption of phosphate on amorphous aluminium hydroxides was investigated using 27 Al and 71 P solid‐state magic‐angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy, following the effect of different exposures to soluble phosphate. The spectra obtained were compared with the spectrum of amorpho…

One goal in molecular magnetism is the synthesis of clusters containing large numbers of coupled spins. In the title heteropolyanion three reconstituted Keggin like fragments [PCo 3 W 9 O 40 ] are assembeled to increase the spin nuclearity. The Figure shows the idealizedstructure of the Co 9 cluster, illustrating the…
The degradation of sheets of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (BIOPOL) by aerobic sewage sludge was analyzed. Degradation of the polymer was highly dependent on the pH of the culture medium and was maximal between pH 7 and pH 8.5. Below pH 6 and above pH 9 the degradation rate was very low. Agitation of th…
We have investigated the thermodynamic interactions as functions of component volume fraction φ and temperature T in six binary polymer blend systems. The components in all cases were model polyolefins, made by saturating the double bonds of nearly monodisperse polydienes. Small-angle neutron scattering measurements f…
This review is concerned with three types of physical phenomena which are affected by the environment of the species under study. They are the vibrational spectrum, nonlinear optical properties, and nuclear magnetic shielding of the molecule (or atom) of interest. The two types of environment discussed are liquid solv…

We have isolated and characterised the gene encoding the glycolytic enzyme enolase (2-phospho-D-glycerate hydrolase) from the human malaria parasite Plasmodium falciparum. This was achieved using a combination of cDNA sequencing and inverse-PCR techniques. The gene maps to chromosome 10 of the parasite. We have also m…
The crystal structure of mitochondrial malate dehydrogenase from porcine heart contains four identical subunits in the asymmetric unit of a monoclinic cell. Although the molecule functions as a dimer in solution, it exists as a tetramer with 222 point symmetry in the crystal. The crystallographic refinement was facili…
Abstract Two methods are presented for calculating the interfacial tension between two immiscible Newtonian fluids. The procedures require only two measurements of the approximate interface shape during the low‐Reynold‐number interfacial‐tension‐driven transient motion of (i) the relaxation of a modestly elongated dro…
