Degradative acetolactate synthase of Bacillus subtilis: purification and properties
A degradative acetolactate synthase (acetolactate pyruvate-lyase [carboxylating], EC 4.1.3.18) from Bacillus subtilis has been partially purified and characterized. The synthesis of the enzyme was induced by growth of cells in minimal medium plus isobutyrate or acetate. The enzyme was partially purified by ammonium su…
Localisation and characterisation of egg shell porphyrins in several avian species
1. Electron microscopy, infra-red analysis and histochemical techniques have been used to determine the site of pigment deposition, the cellular localisation of pigment and the type of pigment precipitated in the egg shells of quail, White Leghorn, Brown Ranger and Black-Headed gull. 2. Transfer of pigment occurs via…

Geometrical and structural relations in the rhombohedral perovskites
The rhombohedral perovskites are of interest in lattice dynamics (e.g. LaAlO3, PrAlO3) and for their ferroelectric properties (e.g. LiNbO3, PbZr/TiO3). In this paper, data scattered through the literature are correlated, with correction of some misleading mistakes of calculation. Geometrical descriptions are put in a…

Statistical mechanics of dense ionized matter. III. Dynamical properties of the classical one-component plasma
We present extensive molecular-dynamics (MD) computations of the time-dependent correlation functions of the classical one-component plasma over a wide range of thermodynamic states characterized by the dimensionless parameter $\ensuremath{\Gamma}=\frac{{e}^{2}}{a{k}_{B}T}$, where $a$ is the ion-sphere radius. The com…

The quantitative analysis of thin specimens
SUMMARY Results are reported concerning the use of an energy dispersive X‐ray detector to carry out the analysis of thin foils in the electron microscope. The combination of a thin specimen and the extreme stability of the energy dispersive X‐ray detector enables the experimental determination of a calibration curve o…
Charge-density waves and superlattices in the metallic layered transition metal dichalcogenides
The d1 layer metals TaS2, TaSe2, NbSe2, in all their various polytypic modifications, acquire, below some appropriate temperature, phase conditions that their electromagnetic properties have previously revealed as ‘anomalous’. Our present electron-microscope studies indicate that this anomalous behaviour usually inclu…
Extreme Toxicity from Combustion Products of a Fire-Retarded Polyurethane Foam
The products from nonflaming combustion of wood and a trimethylol-propane-based rigid-urethane foam that was not fire-retarded produced elevated carboxyhemoglobin levels but no abnormal neurological effects. However, when this type of foam contained a reactive phosphate fire retardant, the combustion products caused g…
Peierls structure transition in quasi-one-dimensional crystals
This review is concerned with the structure, electrical, and optical properties of mixed-valence platinum complexes of the K2 Pt(CN)1, Br0.303H2O type and of TTF-TCNQ salts. Special attention is paid to the experimental results on the anisotropy of electron motion in these quasi-one-dimensional crystals. The theory of…
Flow induced polymer chain extension and its relation to fibrous crystallization
Abstract This work examines the effect that appreciable molecular extension has on the crystallization of long chain molecules. Elementary theoretical considerations presented indicate that to achieve high molecular extensions in solution a longitudinal velocity gradient of strain rate about 103s-1 is required. A meth…
