1. Seismic Pressures in Offshore Areas: Numerical Results
Abstract The purpose of this study is to obtain numerical estimations of seismic pressures in offshore areas considering the effect of seabed configurations and soil materials. To this end, the Boundary Element Method is used to irradiate waves, so that force densities can be obtained for each boundary element. From this hypothesis, Huygens´ Principle is im

2. Propriedades sísmicas anisotrópicas derivadas da orientação cristalográfica preferencial de muscovita-quartzo milonitos
Seismic wave propagation in organized matter usually results in azimuthal variations of longitudinal waves (Pwaves), as well as the effect of birefringence in transversal waves (S-waves), which results in two orthogonal shear waves with contrasting velocities. In this paper we present the results of the anisotropic seismic properties of five samples of musco

3. "Crustal structure of central sector of Tocantins Province by using P and S waves as well as reflected phases with deep seismic refraction data" / "Estrutura crustal do setor central da província Tocantins utilizando ondas p, s e fases refletidas com dados de refração sísmica profunda"
Esta pesquisa está baseada na execução de duas linhas de refração sísmica profunda de 300 km de extensão (L1-Porangatu e L2-Cavalcante) atravessando de oeste para leste o setor central da Província Tocantins, utilizando em cada linha 120 sismógrafos digitais e explosões com tempo controlado e cargas entre 500 e 1000 kg de explosivos a cada 50 km; f

4. Shear waves in the diamond-anvil cell reveal pressure-induced instability in (Mg,Fe)O
The emerging picture of Earth's deep interior from seismic tomography indicates more complexity than previously thought. The presence of lateral anisotropy and heterogeneity in Earth's mantle highlights the need for fully anisotropic elasticity data from mineral physics. A breakthrough in high-frequency (gigahertz) ultrasound has resulted in transmission of

5. The detection of monosynaptic connexions from inspiratory bulbospinal neurones to inspiratory motoneurones in the cat.
Simultaneous recordings were made of the discharges of inspiratory bulbospinal neurones and phrenic or external intercostal alpha-motoneurones in the anaesthetized cat. The connexions between these neurones were studied by the construction of cross-correlation histograms from their discharges. Peaks observed in the cross-correlation histograms were divided i
