    Notes:
    The characteristics of the magnetized plasma obtained in a modified double-plasma device are presented. Primary ionizing electrons are produced by filament discharges in multipole devices located on either end of a magnetized plasma column. A very uniform magnetized plasma is produced in the column with a relatively small number of filaments by using coils to counterbalance the fringing field near the filaments. The obtained plasma is well suited for a large variety of wave experiments. The noise is maintained at a low level and the afterglow measurements reveal a very efficient confinement of the ionizing electrons, with a decay time of 0.2 ms.

    Abstract The hypothesis that the extent of geochemical evolution of lateritic iron oxides gives an indication of the relative age of the laterite is tested on a vertical profile in a gold mine near Kalgoorlie using Mössbauer spectroscopy and X-ray diffraction. No correlation between the structural or compositional properties of the iron oxides and their depth in the profile is found.

    Notes:
    Abstract: The various dynamical regimes of collisional drift waves in a magnetized plasma column are experimentally studied. These unstable low-frequency electrostatic waves are related with strong modulations of the ion and electron density. The angular velocity of the rotating plasma column is the control parameter of the dynamics: regular, chaotic and turbulent regimes are obtained. The spatial extension of the system allows for the occurrence of spatiotemporal chaos. The time-delay auto-synchronization method of controlling chaos [K. Pyragas, Phys. Lett. A 170, 421 (1992)] though purely temporal is successfully applied. A numerical study using coupled nonlinear oscillators exhibiting chaos is compared to the experimental results. The control method is tested on this model.

    Abstract 57Fe Mössbauer spectra of the mineral cores of various ferritins show both paramagnetic and superparamagnetic relaxation effects and in some cases a combination of both. Correlations have been observed between data on the crystallinity, phosphate content and percentage iron in the cores and their magnetic ordering and mean blocking temperatures derived from the Mössbauer spectra.

    Notes:
    Abstract Biological deposition of solid Fe-containing phases can be studied using57Fe Mössbauer spectroscopy. Other techniques are needed in order to understand this complex process. These include proton-induced X-ray and γ-ray emission (PIXE/PIGME), electron microscopy, electron and X-ray diffraction, infrared spectroscopy and chemical characterization of organic components. This paper reviews and evaluates the application of these techniques to biological mineralization of Fe, particularly that occurring in the radula teeth of the marine molluscs, chitons and limpets.

    Abstract Mössbauer spectra of the microcrystalline cores of thalassaemic human spleen ferritin and haemosiderin in applied magnetic fields have shown that the magnetic anisotropy dominates over the energy term arising from the net magnetic moments of the microcrystals in the applied field. The spectra have been analysed to give information on the net magnetic moments of the protein cores.

    Abstract Mature radula pieces from the chitonAcanthopleura hirtosa were studied using Mössbauer spectroscopy. The magnetite present in the radulae was found to have a distribution of Verwey transition temperatures in the range 85–100K. It was deduced that the magnetite was non-stoichiometric with an average formula Fe2.98O3. About 10% of the Fe in the radulae was in the form of maghemite and about 19% was in the form of paramagnetic or superparamagnetic phases.

    Notes:
    Abstract The principal forms of storage-iron in the lamprey,Geotria australis, are haemosiderin in the nephric fold of the larval animal and ferritin in the liver of the adult. Mössbauer spectroscopy of the larval haemosiderin showed that about half of the iron was in the form of ferrihydrite (5Fe2O3.9H2O) with the remainder being in the form of a non-crystalline iron oxyhydroxide, suggesting two modes of biomineralization. The cores of the adult liver ferritin gave spectral parameters indicating the iron to be predominantly in the form of ferrihydrite with about 10% being in a non-crystalline phase.

    Notes:
    Abstract Mössbauer spectra were recorded of tissue from β-thalassaemia/haemoglobin E spleen, liver, pancreas and heart and of crude haemosiderins (insoluble iron fractions) isolated from the organs. Iron in the crude haemosiderins from the spleen and heart remains paramagnetic below 4.2K indicating that the iron is in a non-crystalline form. Superparamagnetic behaviour of the crude haemosiderins from the pancreas and liver indicate the presence of ferrihydrite cores with some cores with a structure based on defect-goethite.

    Notes:
    Abstract A sample of liver from the marine mammalDugong dugong was found to have an iron concentration of 137 000 Μg g−1 Fe dry weight. Histological examination of the tissue revealed dense extracellular deposits of iron-containing particles about 40 to 80 Μm in diameter. Mössbauer spectra of the sample at temperatures between 17 and 200 K show superparamagnetic behaviour with a mean superparamagnetic blocking temperature of about 67 K, with the sextet being extinguished between 160 and 200 K. The blocking temperature and spectral parameters are indicative of the goethite-like form of hemosiderin that has previously been reported in some iron-loaded thalassemic human tissues.

    Notes:
    Abstract Mössbauer spectra of 12 normal human spleen and 12 normal human liver samples (post mortem) from Australia and Thailand have been recorded at 78 K. The spectra show the presence of iron in the form of ferrihydrite, together with some deoxyhemoglobin and methemoglobin in some samples. The spectra were used in conjunction with elemental analysis to calculate the non-heme iron concentrations in the tissues. The mean non-heme iron concentration in the Thai livers was significantly less than that for the Australian samples. The goethite-like form of hemosiderin that has been observed in some pathological tissues was not detected.

    Abstract Mössbauer and electron paramagnetic resonance (EPR) spectra of pigment gallstones were recorded at room temperature. Iron in the gallstones was found to be high-spin iron(III) with some or all of the iron being in a site of low symmetry, giving a g=4.28 signal in the EPR spectrum. Spectra of a sample of bilirubin indicated that the iron in the gallstones was not in the form of the iron-bilirubin complex. Elemental analysis also showed the presence of Cu, Mn, Zn, and Pb in addition to the Fe.
