the work presented in this paper investigates the causes of size effects in structural-concrete members. it isbased on the use of a finite-element model found to yield realistic predictions of structural-concrete behavior in allcases investigated to date. in fact, the previous use of this model in investigations of size effects in reinforced-concretebeams indicated that such effects reflect the...

 In this work, Fe/TiO2 nanostructured catalyst was prepared using sol-gel method developed by Yoldas and tested in degradation of phenol in water under UV radiation.  The synthesized catalyst was characterized by XRF, XRD, specific surface area and porosimetry, and SEM methods. The porosimetry revealed the mesopore structure of the catalyst. Results of SEM confirmed the nano dispersion of  iron...

The Royal College of Physicians states that "handover, particularly of temporary 'on-call' responsibility, has been identified as a point at which errors are likely to occur."[1] Working a weekend on-call covering medical wards is often busy and stressful for all junior doctors. The high volume of routine and unplanned tasks make the situation even worse. In Nevill Hall hospital Abergavenny, we...
