Soft soil has a small shear strength, large compressibility, and also coefficient of permeability. So that soft can be used as the basis construction, improvement measures are needed. One method is stone column. in this research, parametric study effect column on bearing capacity was carried out. Parameters were varied diameter, distance angle configuration pattern. Variations diameter 1 m, 1.2...

Rhinolith is stone formation within the nasal cavity. We describe a case of large rhinolith of right nasal cavity in a 51 yrs old female with history of foul smelling right nasal discharge and right epiphora. The rhinolith was removed using rigid nasal endoscope.

To investigate the seismic behavior of end-plate connection semi-rigid space steel frames, three 1/4-scale specimens were tested under cyclic load. Finite element analysis which took initial geometric imperfections into consideration was also conducted, and the results conform to experimental results. The failure modes, hysteretic behavior, deformation capacity and energy-dissipation capacity o...

Potamotrygon limai, sp. nov., is described from the Jamari River, upper Madeira River system (Amazon basin), state of Rondônia, Brazil. This new species differs from congeners by presenting unique polygonal or concentric patterns formed by small whitish spots better defined over the posterior disc and tail-base regions. Potamotrygon limai, sp. nov., can be further distinguished from congeners i...
