    : In dermatology, patients with nodosum leprosum and discoid lupus erythematosus are benefited by clofazi-mine therapy. Its use in other autoimmune diseases has to be considered. Patients with lupus pernio may respond to this regime, but further prolonged trials will have to be undertaken.

    Notes:
    Ammonia chemisorption on a small and positively charged gallium arsenide cluster in the gas phase has been investigated using density-functional methods. The reactivity at various cluster sites are characterized in terms of binding energy and charge transfer from the adsorbate to the cluster with a strong correlation shown between the latter two quantities. The calculations show a strong dependence of the reactivity of the cluster on its charge state. Ionizing the bare cluster to a cationic charge state enables multiple chemisorption of ammonia, which is much less favored by a neutral cluster and can be prohibited on a negatively charged cluster. © 1996 American Institute of Physics.

    Notes:
    It is well known that the chemical reactivity of small gallium–arsenide clusters can be sensitive to cluster size and geometrical structure. We have performed ab initio calculations probing the interaction of NH3 with different sites of a free Ga5As5 cluster. Our results show that bonding tends to be strongest at gallium sites. Adsorption of NH3 is found to induce strong relaxation of the cluster global geometry. The cluster sites are compared with sites on the (111) bulk surface of gallium arsenide, and the possibility for exploring the similarity between cluster reactivity and surface reactivity is discussed.

    Notes:
    We present an investigation of the interaction of two ammonia molecules with the Ga5As5 cluster. The (NH3)2Ga5As5 complex is found to be stable, in agreement with experiments. We find a significant decrease in the binding energy for the second ammonia, compared to single ammonia adsorption in agreement with experimental results. We investigate the site dependence of the ammonia–ammonia interaction and demonstrate that the adsorption of a single ammonia on certain sites prevents further adsorption of ammonia on certain other sites. © 1995 American Institute of Physics.

    Notes:
    An effective method for reducing the formation of curd in canned salmon is described. The process consists of applying an aqueous extract of papaya latex powder to the surfaces of raw salmon segments prior to conventional vacuum seaming and heat sterilization. It is based on the idea that large curd-forming proteins, once reduced to peptide and polypeptide fragments, will no longer coagulate when heated. A substantial reduction in curd formation was achieved in canned coho and sockeye salmon.

    Summary This paper describes a preliminary investigation of the mechanisms of Fe(II) oxidation and storage of Fe(III) in the bacterioferritin ofEscherichia coli (EcBFR). Using Mössbauer spectroscopy to examine the initial oxidation of iron by EcBFR we have confirmed that this ferritin exhibits «ferroxidase» activity and have shown that dimeric and monomeric iron species are produced as intermediates. We compare the characteristics of ferroxidase activity in EcBFR with those of human H-chain ferritin (HuHF) and discuss the different Mössbauer parameters of their dimeric iron with reference to the structures of their di-metal sites. In addition, we present preliminary findings suggesting that after an initial «burst», the rate of oxidation is greatly reduced, possibly due to blockage of the ferroxidase centre by bound iron. A new component, not found in HuHF and probably representing a small cluster of Fe(III) atoms, is reported.

    Notes:
    Summary There is widespread uncertainty about the nature and role of morphological plasticity in resource competition in plant communities. We have assayed the foraging characteristics of leaf canopies and root systems of eight herbaceous plants of contrasted ecology using new techniques to create controlled patchiness in light and mineral nutrient supply. The results are compared with those of a conventional competition experiment. Measurements of dry matter partitioning and growth in patchy conditions indicate a consistent positive association between the foraging characteristics of roots and shoots, supporting the hypothesis of strong interdependence of competitive abilities for light and mineral nutrients. Differences are identified in the abilities of dominant and subordinate plants to forage on coarse and fine scalcs. It is suggested that a trade-off exists in the scale (“high” in dominants) and precision (high in subordinates) with which resources are intercepted and that this trade-off contributes to diversity in communities of competing plants.

    Notes:
    Abstract Human brain (globus pallidus) and liver tissues were investigated by means of electron microscopy (EM), Mössbauer spectroscopy (MS) and SQUID magnetometry techniques. Based on MS measurements, the iron present was identified to be in the ferritin-like form (61–88%) and in the form of a low-spin iron species (the balance). Its overall concentration was estimated as 1.5(3) mg in the brain and 2.4(5) mg in the liver, per gram of lyophilized tissue. The average core diameter was determined by EM measurements to be equal to 7.5(1.3) nm for the liver and 3.3(5) nm for the brain. Magnetization measurements carried out between 5 and 300 K yielded an estimation of an average blocking temperature, KT BL, as equal to 6.7 K and 8.5 K for the liver and the brain, respectively. From the dependence of KT BL on the external magnetic field it was concluded that the ferritin-like cores in the studied samples can be regarded as non-interacting particles. Finally, the uniaxial magnetic anisotropy constant was determined to be 6×103 J/m3 for the liver and 4×104 J/m3 for the brain.
