1. Investigation of the Elastic Properties of Graphenylene Using Molecular Dynamics Simulations
Molecular dynamics simulations are used here to study the mechanical behavior of graphenylene under uni-directional and bi-directional loadings. The effects of nanosheet chirality and size on Young's modulus of graphenylene are investigated. Compared to graphene, graphenylene possess a smaller elastic modulus. It is shown that for large armchair and zigzag g

2. Fragmentação por ação aerotermodinâmica e predição da área de impacto de um veículo espacial com injeção controlada da re-entrada / Aerothermodynamically-induced fragmentation and prediction of the area of impact of a space vehicle with controlled injection of the re-entry
Este trabalho consiste em estudar a fragmentação por ação aerotermodinâmica durante re-entrada de um veículo espacial, com estimativa da área de impacto dos fragmentos na superfície terrestre. Inicialmente, são realizadas manobras de decaimento orbital controlado através de transferências ótimas impulsivas. Tais impulsos são aplicados no sentido

4. Aspectos Morfo-Dinâmicos daComplexo Lagunar Nísia Floresta-Papeba-Guaraíras, Região Costeira Sul Oriental Do RN
This dissertation presents the results of research developed in the Nísia Floresta-Papeba-Guaraíras Lagoon Complex, located on the south coast of the Rio Grande do Norte State. The main objectives of this dissertation were the stratrigraphic characterization, in detail scale, of the and the coastal dynamics study of the lagoonal deposits sedimentation, as

5. Fracture dynamics of fusion of two anti-plane cracks
The problem of the fracture dynamics of two two-dimensional coplanar anti-plane shear cracks is considered. Both cracks extend under a critical stress-intensity fracture criterion. The two cracks are initiated at different locations and times. A solution developed by Kostrov [Kostrov, B. V. (1966) J. Appl. Math. Mech. 30, 1241-1248] for isolated cracks is us

6. The Aftermath of Hip Fracture: Discharge Placement, Functional Status Change, and Mortality
The authors prospectively explored the consequences of hip fracture with regard to discharge placement, functional status, and mortality using the Survey on Assets and Health Dynamics Among the Oldest Old (AHEAD). Data from baseline (1993) AHEAD interviews and biennial follow-up interviews were linked to Medicare claims data from 1993–2005. There were 495

7. Surface dynamics in living acinar cells imaged by atomic force microscopy: Identification of plasma membrane structures involved in exocytosis
The dynamics at the plasma membrane resulting from secretory vesicle docking and fusion and compensatory endocytosis has been difficult to observe in living cells primarily due to limited resolution at the light microscopic level. Using the atomic force microscope, we have been able to image and record changes in plasma membrane structure at ultrahigh r
