Surface litter from a natural and a sewage-enriched cypress dome in north-central Florida showed a pronounced seasonal pattern of nitrogenase (acetylene reduction) activity associated with seasonal leaf fall from deciduous trees in the domes. Samples of peat from cores indicated negligible nitrogenase activity below the surface layer. Integrating the monthly rates of nitrogen fixation (based on...
Abstract This paper presents some results of research aimed at defining a parametric tool for modelling complex decorative apparatuses domes based on geometric rules definition and building techniques. MaTiDo , Majolica Tiles Domes, is an adaptive that allows user to place “fish scale” revolution oval or elliptical ones, with ribs without ribs. can be used reproduce the look real virtually reco...
At the surface of the Earth, volcanism is found in several tectonic contexts. It is largely concentrated at the plate margins: at divergent plate boundaries, mid-oceanic ridges, where new tectonic plates are created, and at convergent margins, subduction zones, where the lithospheric plates dive into the mantle. In the interior of the oceanic plates, we find however linear volcanic chains, comp...
for an Invited Paper for the MAR05 Meeting of The American Physical Society Unified description of the formation and evolution of self-organized quantum dots in the InAs/GaAs(001) and Ge/Si(001) systems GIOVANNI COSTANTINI, Max-Planck-Institut fuer Festkoerperforschung Self-organised semiconductor quantum dots, epitaxially grown on lattice-mismatched substrates, are promising candidates for the...
Formation water analyses of Tertiary reservoir (Euphrates, Jeribe, and Dhiban formations) in Hemrin oilfield reflect high salinity variation between Albufudhul, Nukhaila, Allas domes. The present study suggests that this resulted by two reasons, (1) percolation surface waters (rain water) which lead to devastation oil type, (2) interaction host rocks. Satellite image DEM were used detect the li...
Synthetic aperture radar imagery is widely used to study surface deformation induced by volcanic activity; however, it is rarely applied to quantify the evolution of lava domes, which is important for understanding hazards and magmatic system characteristics. We studied dome formation associated with eruptive activity at Mount Cleveland, Aleutian Volcanic Arc, in 2011–2012 using TerraSAR-X imag...
Pressure dependence of the electronic and crystal structures of KxFe2-ySe2, which has pressure-induced two superconducting domes of SC I and SC II, was investigated by x-ray emission spectroscopy and diffraction. X-ray diffraction data show that compressibility along the c-axis changes around 12 GPa, where a new superconducting phase of SC II appears. This suggests a possible tetragonal to coll...
The paper provides a methodology for finding a family of patterns for lattice domes, created based on the “Surface Sphere Packing” concept. The patterns have a high degree of regularity in the sense of a high percentage of the elements being of the same length. Also, parametric formulation for generating such patterns are discussed. This gives an opportunity for creating more regular patterns w...
