Constraints on SUSY Seesaw from Leptogenesis and LFV

We study constraints on the fundamental parameters of supersymmetric type I seesaw models imposed by neutrino data, charged lepton flavor violation, thermal leptogenesis and perturbativity of the neutrino Yukawa couplings.Comment: 4 pages, 2 figures, to appear in Proceedings of SUSY06, the 14th International Conference on Supersymmetry and the Unification of Fundamental Interactions, UC Irvine, California, 12-17 June 200

Weathering And Behavior Of Gold In Two Soil-saprolite Sequences Near Camden, South Carolina

Prolonged weathering under subtropical conditions has resulted in development of 40 m thick weathered profiles at the Ridgeway North gold deposit and the Heath Springs prospect in the Piedmont of South Carolina, developed on late Precambrian to Cambrian(?) rocks of the Carolina Slate Belt. At Ridgeway, fine-grained quartz-muscovite-pyrite phyllites contain gold grains which are predominantly {dollar}{dollar}900. At Heath Springs, the steeply-dipping zone of pyrite-rich quartz-muscovite-microcline-sillimanite granofels probably formed by metamorphism of a quartz-muscovite-pyrite phyllite, upon intrusion of the Liberty Hill Pluton.;Vertical zonation at both sites is, from bottom to top: fresh bedrock; saprolite; massive zone, and; soil, an Ultisol. Petrologic, bulk density, particle-size, clay and geochemical data all reflect this zonation. Quartz dissolution, and alteration of feldspars and micas to clay minerals (including kaolinite, illite, smectite and HIV), are the predominant changes. Mass balance calculations, assuming immobility of Ti and/or Zr, and constrained by specific gravities, indicate removal of large amounts of material during weathering, resulting in volume losses up to 30% in saprolite, and as much as 60% in soils.;Gold has been leached from soils at both sites, and from weathered zones at Ridgeway, to be redeposited in zones at depth. Iron ozide- and oxyhydrozide-rich features in soils are, however, greatly enriched in gold relative to background. Gold grains, some of which are delicate crystals, are larger and of different composition than those known from fresh rock. Grains of fineness {dollar}\sim{dollar}830 are predominant, with electrum (f 500-800) present as overgrowths. Gold of f {dollar}\u3e{dollar} 990 occurs as small discrete grains, and veins and rims on silver-rich gold particles. Transport of gold in the weathering zone probably involved thiosulphate-, hydroxy-, chloride- and organic-complexes

Medium-modified DGLAP evolution of fragmentation functions from large to small x

The unified description of fragmentation function evolution from large to small x which was developed for the vacuum in previous publications is now generalized to the medium, and is studied for the case in which the complete contribution from the largest class of soft gluon logarithms, the double logarithms, are accounted for and with the fixed order part calculated to leading order. In this approach it proves possible to choose the remaining degrees of freedom related to the medium such that the distribution of produced hadrons is suppressed at large momenta while the production of soft radiation-induced charged hadrons at small momenta is enhanced, in agreement with experiment. Just as for the vacuum, our approach does not require further assumptions concerning fragmentation and is more complete than previous computations of evolution in the medium

Electric properties of granitic rocks

The objective of this work is to clarify the role of water content on the charge trans- port mechanisms of different granitic rocks. The mineralogical content of the rocks will also be taken into account. From the electrical point of view these materials are rather insulating porous media where charge injection creates different phenomena like build-up charges, space charge limited currents, surface effects and other behav- iors that resemble much a variety of oxides, like AlO

Distinct magnetic signatures of fractional vortex configurations in multiband superconductors

Vortices carrying fractions of a flux quantum are predicted to exist in multiband superconductors, where vortex core can split between multiple band-specific components of the superconducting condensate. Using the two-component Ginzburg-Landau model, we examine such vortex configurations in a two-band superconducting slab in parallel magnetic field. The fractional vortices appear due to the band-selective vortex penetration caused by different thresholds for vortex entry within each band-condensate, and stabilize near the edges of the sample. We show that the resulting fractional vortex configurations leave distinct fingerprints in the static measurements of the magnetization, as well as in ac dynamic measurements of the magnetic susceptibility, both of which can be readily used for the detection of these fascinating vortex states in several existing multiband superconductors.Comment: 5 pages, 4 figure

A contribution to the knowledge of Bactrocera oleae (GMEL) in Tras-os-Montes region (northeastern Portugal): phenology, losses and control

Severe damage is caused by the olive fly (Bactrocera oleae (Gmel)) in the Trás-osMontes region. In order to develop a control strategy, two olive groves for oil production ("Cobrançosa" and "Verdeal") and one for table olive ("Negrinha de Freixo") were assessed ( 1993-1996). The insect phenology, yield losses and fruit infestation were evaluated. The insect's peak flight period occurred during the first half of October. Severe yield losses due to the pest occurred in 1995, reaching 19 % of the total harvest. It is concluded that earlier harvesting (second half of September) can avoid substantial losses because the main period of infestation in all years occurred in October
