SEISMIC BEHAVIOR OF RESILIENT REINFORCED CONCRETE COLUMNS WITH ULTRA-HIGH-STRENGTH REBARS UNDER STRONG EARTHQUAKE-INDUCED MULTIPLE REVERSED CYCLIC LOADING

The frequent occurrence of major earthquakes highlights the structural challenges posed by long-period ground motions (LPGMs).This study investigates the seismic performance and resilience of five reinforced concrete (RC) columns with different high-strength steel bars under LPGM-induced cyclic loading, both experimentally and numerically.The resul

The issue of drilling mud multiple use is problematic.To reuse, the solution must be efficiently cleaned from solid particles according to the class of 0.04-0.07 mm.An analysis of existing technologies and equipment has shown that drilling mud regeneration schemes are rather difficult to operate and expensive.In world practice there has been a tend

Chronic renal failure (CRF) represents the major cause of mortality in the nephro-logy unit in Ivory Coast because the means for appropriate management are lacking.The present study was performed to investigate the risk factors for CRF so that strategies for prevention could be elaborated.A case-control study was performed prospectively at the Yopo

Lumbar interbody fusion (IF) is a common procedure to obtain fusion of the spine by replacement of the intervertebral disc with a cage.Optimization of spinal cages is ongoing to reduce complications such as a pseudoarthrosis and subsidence of the cage.IF animal models (primate, dog, pig, goat and sheep) remain important to assess implant effectivit
