A 42-year-old woman was referred to our institution with sudden onset of ataxia, facial paresis, horizontal gaze palsy, and progressive dysarthria. The patient worsened within a few minutes, with appearance of left hemiparesis. The National Institutes of Health Stroke Scale Score was 13. On computer tomography scan 2 hours after stroke onset, no brain stem lesion or intracranial bleeding was vi...

Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...

the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

This paper presents an in-situ inspection and experimental investigation on the pore solution pH of concrete cover for the corrosion initiation of rebars under a long-term natural carbonation reaction. A 77-year-old steel mill was inspected, and 35 concrete column cover samples were collected to test the pH of the pore solution and phase compositions layer by layer. The variation in pH and phas...

This paper deals with an experimental study on the tensile performance of recently developed “FRP Hybrid Bars” by authors. The objective of this study is to investigate tensile strength of FRP Hybrid Bars and to overcome the shortcomings of the FRP material with its low elastic modulus. This uses the concept of material hybridization to increase elastic modulus to be used in concrete structures...

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by tw...
