Non-missile intracranial injuries caused by foreign bodies are quite uncommon in civilian practice. Nails, knives, screwdrivers and sewing needles are the most commonly reported agents. The authors report a unique case of an adult male patient who suffered a penetrating craniocerebral injury caused by a falling concrete reinforcing iron (rebar) from the fourth floor of a buildin...

We also targeted emergent fauna for manipulation, choosing elimination over enhancement as a more practical manipulation. Treatments consisted of smoothing 4-m2 plots by hand and covering them with black plastic weighed down by rebar to smother the underlying fauna. Paired controls included smoothing and rebar, but no plastic. After about 3 d, the plastic was removed to monitor the effects of r...

Steel-fiber-reinforced concrete (SFRC) is a composite material made by randomly distributing short steel fibers in normal (NC). In this study, central pull-out tests of 32 specimens were performed to investigate the bond behavior between high-strength rebar and SFRC under influence fraction fiber volume (Vf = 0%, 0.5%, 1.0% 1.5%) temperature (T 20, 200, 400 600 °C). The results show that NC spe...

As a novel civil engineering material, Engineered Cementitious Composite (ECC) has attracted more and attention due to its strain-hardening characteristics, good post-cracking resistance unique properties. Bonding between rebar great effect on the mechanical behavior of structural members. In this paper, direct pull-out tests were conducted understand bond ECC rebar. The test parameters include...

Abstract The structural behaviour of hybrid reinforced concrete beams trapezoidal section was investigated in this work. main aim study to investigate the interaction effect compressive strength–section geometry variations on beam strength characteristics. experimental programme included fourteen simply supported deep being prepared and examined under a four-point load setting protocol. All spe...

stress-corrosion cracking (scc) tests were conducted in the near-neutral ph standard solution, ns4, and in an actual soil solution, using four-point bending at a high stress ratio and low frequency conditions very similar to those of operational pipelines. pitting incubation appeared first and then pitting initiated and grew in both solutions although there were many more pits on the specimen t...
