In-situ strength assessment of concrete - The European Concrete Frame Building Project (Reprinted from Non-Destructive Testing Civil Engineering, April, pg 583-592, 2000)

A full-scale seven-storey in-situ advanced reinforced concrete building frame was constructed in the Building Research Establishment's Cardington laboratory encompassing a range of different concrete mixes and construction techniques. This provided an opportunity to use in-situ non-destructive test methods, namely Lok and CAPO tests, on a systematic basis during the construction of the building. They were used in conjunction with both standard and temperature-matched cube specimens to assess their practicality and their individual capabilities under field conditions. Results have been analysed and presented to enable comparisons of the performance of the individual test methods employed.

Radiochromic film spectroscopy of laser-accelerated proton beams using the FLUKA code and dosimetry traceable to primary standards

A new approach to spectroscopy of laser induced proton beams using radiochromic film (RCF) is presented. This approach allows primary standards of absorbed dose-to-water as used in radiotherapy to be transferred to the calibration of GafChromic HD-810 and EBT in a 29 MeV proton beam from the Birmingham cyclotron. These films were then irradiated in a common stack configuration using the TARANIS Nd:Glass multi-terawatt laser at Queens University Belfast, which can accelerate protons to 10-12 MeV, and a depth-dose curve was measured from a collimated beam. Previous work characterizing the relative effectiveness (RE) of GafChromic film as a function of energy was implemented into Monte Carlo depth-dose curves using FLUKA. A Bragg peak (BP) "library" for proton energies 0-15 MeV was generated, both with and without the RE function. These depth-response curves were iteratively summed in a FORTRAN routine to solve for the measured RCF depth-dose using a simple direct search algorithm. By comparing resultant spectra with both BP libraries, it was found that the effect of including the RE function accounted for an increase in the total number of protons by about 50%. To account for the energy loss due to a 20 mu m aluminum filter in front of the film stack, FLUKA was used to create a matrix containing the energy loss transformations for each individual energy bin. Multiplication by the pseudo-inverse of this matrix resulted in "up-shifting" protons to higher energies. Applying this correction to two laser shots gave further increases in the total number of protons, N of 31% and 56%. Failure to consider the relative response of RCF to lower proton energies and neglecting energy losses in a stack filter foil can potentially lead to significant underestimates of the total number of protons in RCF spectroscopy of the low energy protons produced by laser ablation of thin targets.

Article 6 ECHR, Civil Rights and the Enduring Role of the Common Law

This article examines the role that the common law has played in Human Rights Act 1998 case law on the protection of 'civil rights' within the meaning of Article 6 ECHR. Focusing on Article 6 ECHR's 'disclosure' and 'full jurisdiction' requirements, it highlights an increasingly nuanced relationship between the ECHR and common law in cases under and outside the Human Rights Act 1998. Although the general pattern within the case law has been one of domestic court fidelity to the ECHR - something that is wholly consistent with section 2 of the Human Rights Act 1998 - the article notes areas in which the courts have been reluctant to adapt common law principles, as well as instances of common law protections exceeding those available under Article 6 ECHR. The article suggests that such lines of reasoning reveal a robustness within the common law that brings a multi-dimensional quality to the Human Rights Act 1998. It also suggests that such robustness can be analysed with reference to 'common law constitutionalism' and a corresponding imagery of 'dialogue' between the domestic courts and European Court of Human Rights.

Military Service Pensions for public and civil servants in independent Ireland

In 1924 the Cumann na nGaedheal government introduced the first Military Service Pensions Act to provide monetary compensation for those who fought for Irish independence between 1916 and 1923. Pensioners who were in receipt of remuneration from the state as civil and public servants had a portion of their pension deducted commensurate with their state income. This controversial provision was criticised by all political parties as representing a mean-spirited attitude towards veterans of the independence campaign and treating civil and public servants differently from those in private employment. It was eventually modified in the 1940s and abolished in the 1950s. This article provides a case study that highlights the parsimonious attitude of Irish governments towards veterans of the independence campaign and shows how the treatment of public and civil servants reflected tensions between the government and the civil service in the early years of the state.
