Propagation of uncertainties and multimodality in the impact problem of two elastic bodies
(Elsevier, 2013-10)
An uncertainty quantification study is carried out for the problem of the frontal collision of two elastic bodies. The time of contact and the resultant force function involved during the collision are the quantities of ...
Dynamical effects in the segregation of granular mixtures in quasi 2D piles
(Elsevier, 2015-01)
The dynamics of segregation, mixing and layering is studied during the build-up of quasi-2D piles of two different species of grains of different diameters (i.e. 1 mm glass beads and either 3 mm glass beads or 3.1 mm ...
An inner warp in the DoAr 44 T Tauri transition disc
(Oxford University Press, 2018-07)
Optical/IR images of transition discs (TDs) have revealed deep intensity decrements in the rings of HAeBes HD 142527 and HD 100453 that can be interpreted as shadowing from sharply tilted inner discs, such that the outer ...
New insights on the Lewis acidity of diorganolead(IV) compounds: Diphenyllead(IV) complexes with N,O,S-chelating ligands
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The reactions of PbPh2(OAC)(2) with alkylglyoxylate thiosemicarbazones (HRGTSC, R = Et, Bu) afforded complexes of the type [PbPh2(GTSC)] center dot H2O, [PbPh2(RGTSC)(2)] and [PbPh2Cl(BUGTSC)]. The structures of HRGTSC (R ...
PACKMOL: A Package for Building Initial Configurations for Molecular Dynamics Simulations
(JOHN WILEY & SONS INC, 2009)
Adequate initial configurations for molecular dynamics simulations consist of arrangements of molecules distributed in space in such a way to approximately represent the system`s overall structure. In order that the ...
Photoluminescence study of new lanthanide complexes with benzeneseleninic acids
(ELSEVIER SCIENCE BV, 2010)
New lanthanide complexes with benzeneseleninic (ABSe) and 4-chloro-benzeneseleninic (ABSeCl) acids have been synthesized and characterized by elemental analysis, infrared and UV-visible spectroscopies. The emission spectra ...
Assessment of nose protector for sport activities: finite element analysis
(WILEY-BLACKWELLMALDEN, 2012)
There has been a significant increase in the number of facial fractures stemming from sport activities in recent years, with the nasal bone one of the most affected structures. Researchers recommend the use of a nose ...
Importância da hidrodinâmica na cinética de flotação de partículas grossas
(Escola de Minas, 2010)
The processes that govern the rate of particle recovery in a flotation cell include the following sub-processes: collision, attachment, and stability of the aggregate formed by particles and bubbles. Collision is controlled ...
The Sulfur Shift: An Activation Mechanism for Periplasmic Nitrate Reductase and Formate Dehydrogenase
(American Chemical Society, 2013-09)
A structural rearrangement known as sulfur shift occurs in some Mo-containing enzymes of the DMSO reductase family. This mechanism is characterized by the displacement of a coordinating cysteine thiol (or SeCys in Fdh) ...
Internacionalização do direito e caminhos para a construção de um direito comum europeu: análise da margem nacional de apreciação
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Sociais e Humanas, 2014-11-28)
The evolution of industrial society to the information society brings about significant changes in the legal structures. It is said that today the legal harvest resembles a mosaic, in which a real apparent chaos ensues ...
