ABSTRACT
We provide a database of the surface ruptures produced by the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow earthquake caused about 8 km of surface faulting, along the trace of the NNW-trending active Fiandaca Fault. Detailed field surveys have been performed in the epicentral area to map the ruptures and to characterize their kinematics. The surface ruptures show a dominant right-oblique sense of displacement with an average slip of about 0.09 m and a maximum value of 0.35 m. We have parsed and organized all observations in a concise database, with 932 homogeneous georeferenced records. The Fiandaca Fault is part of the complex active Timpe faults system affecting the eastern flank of Etna, and its seismic history indicates a prominent surface-faulting potential. Therefore, this database is essential for unravelling the seismotectonics of shallow earthquakes in volcanic areas, and contributes updating empirical scaling regressions that relate magnitude and extent of surface faulting.
ABSTRACT
O objetivo do estudo foi avaliar os efeitos da utilização de diferentes arranjos populacionais na implantação de sorgo forrageiro nas características morfogênicas e estruturais do pasto. Os tratamentos foram 22 ou 44cm entrelinhas e 12 ou 24kg de sementes ha-1. O método de pastoreio foi contínuo. Foram utilizadas 36 novilhas, com idade e peso corporal médios de 15 meses de 262kg. As variáveis morfogênicas não foram influenciadas significativamente (P>0,05) pelos arranjos populacionais e pelos períodos de avaliação, sendo obtidos taxa de alongamento e senescência foliar de 1,43 e 1,11cm dia-1afilho-1, respectivamente, taxa de aparecimento foliar e intervalo de surgimento de folhas de 0,28 folhas dia-1afilho-1 e 3,81 dias, filocrono e duração de vida foliar de 72,99 e 351,68 graus dia, nessa ordem. As características estruturais do pasto foram influenciadas pelos períodos de avaliação. Do primeiro para o terceiro período de avaliação, foi verificada uma redução de 65,53% no número de folhas em alongamento e de 47,79% no número de folhas vivas.(AU)
The objective of the study was to evaluate the effects of using different population arrangements in the implementation of sorghum in the morphogenetic and structural characteristics of the pasture. The treatments were 22 or 44cm between rows and 12 or 24kg ha-1 of seed. The grazing method was continuous. The sample consisted of 36 heifers with an average age of 15 months and average body weight of 262kg. Morphogenic variables were not significantly influenced (P>0.05) by population arrangements and evaluation periods, elongation rate and leaf senescence of 1.43 and 1.11cm afilho-1 day-1 being obtained, respectively, and leaf appearance rate of leaf appearance leaves the range of 0.28 day-1 and 1afilho 3.81 days, phyllochron and leaf duration of life of 72.99 and 351.68 degree day, in that order. The structural characteristics of the pasture were influenced by evaluation periods. From the first to the third evaluation period, a reduction of 65.53% in the number of leaves in stretching and 47.79% in the number of living leaves was verified.(AU)

A general procedure for the reliable preparation of large quantities of insoluble transmembrane peptides has been developed. Optimal couplings were obtained during synthesis by using high-temperature couplings in conjunction with O-(7-azabenzotriazol-1-yl)-1,1,3, 3-tetramethyluronium hexafluorophosphate (HATU) activation. Improved purification schemes were developed that use reverse- phase HPLC on a C1 column and elution with a 2:1 mixture of 1-propanol:1-butanol. Using these methods three very different transmembrane peptides all longer than 25 amino acids have been prepared: glycophorin-A, prion (110-137), and fibroblast growth factor receptor (368-397).
