Nanoparticles to Control Stranded Packing of DNAs
Abstract: We report here on new optic and small-angle X-ray scattering (SAXS) measurements concerning the formation of the dispersions from double-stranded (ds) DNA molecules, doped with negatively charged gold nanoparticles (nano-Au). The nano-Au fixation nearby the surfaces of linear ds DNA in solution of high ionic strength (0.3 M NaCl) and subsequent phase exclusion of (ds DNA-nano-Au) complexes from solution containing poly(ethylene glycol) results in decrease in the amplitude of abnormal …

Identification of Axial Air-Foil Bearings and Radial Air-Foil Bearings
Abstract: Air-foil bearings (AFBs) are self-acting hydrodynamic bearings, a shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that there is no contact. The shaft and foil are divided by air's high pressure which is produced by the rotation which pulls gas into the bearing via viscosity effects. AFBs provide …

Numerical Study on the Effect of Ball Baffles in Reducing Sloshing Loads in Ship Tanks
Abstract: Sloshing is the free surface motion of a liquid in a partially filled container under periodic motion. Liquid sloshing will result in dynamic pressure on the walls of the container causing large deformations to the tank as well as the supporting structures and carrier. This dynamic pressure on the tank walls due to slosh waves are conventionally mitigated in the tanks of very large crude oil carrier (VLCC) ships by …

Finite element analysis using Staad-Pro for irregular L-shape Building by Time History Analysis
Abstract: To perform well in an earthquake, a building should possess four main attributes, namelysimple and regular configuration, and adequate lateral strength, stiffness and ductility.Buildings having simple regular geometry and uniformly distributed mass and stiffness inplanes well as in elevation, suffer much less damage than buildings with irregularconfigurations. Impairment can be in the form of loss of non-structural element, damage tostructural components, and collapse of structural element leading to progressive failure …
