The damage mechanisms of biaxial non-crimp-fabric (NCF) reinforced composites with a quasi-isotropic [(45/-45)(90/0)]4s layup subject to low-velocity impact (LVI) and compression-after-impact (CAI) loadings are investigated. Experimental results indicate that fibre compressive failure in the 0° plies controls peak load during CAI, which is influenced by out-of-plane transverse deformation impac...

Four experiments demonstrated implicit self-esteem compensation (ISEC) in response to threats involving gender identity (Experiment 1), implicit racism (Experiment 2), and social rejection (Experiments 3-4). Under conditions in which people might be expected to suffer a blow to self-worth, they instead showed high scores on 2 implicit self-esteem measures. There was no comparable effect on expl...

In the present study, we investigated whether the antiulcer effects of nimesulide (100 mg kg(-1) and ranitidine (150 mg kg(-1) were dependent on the adrenal cortex hormones. The antiulcer effects of nimesulide and ranitidine were examined in the indomethacin-induced gastric ulcer model in rats (first experiment). The mean ulcer areas in the control and ranitidine-treated groups were 11.1 +/- 3....

Material irradiation by protons is capable of simulating the effects of fusion neutrons (14 MeV, target damaging and He & H production) with a reasonably fast dose rate, according to theoretical calculations and previous experiments. Therefore, given that the ESSBilbao (ESS-B) accelerator, under construction in Bilbao, will provide an intense source of 50 MeV protons, with total currents of a f...

Crystal Calorimetry in future high-energy physics experiments faces a new challenge to maintain its precision in a hostile radiation environment. This paper discusses the effects of radiation damage in scintillating crystals, and concludes that the predominant radiation damage effect in crystal scintillators is the radiation-induced absorption, or color center formation, not the loss of scintil...

The ways in which radiation damage affects the properties of silicon microstrip detectors are reviewed and discussed in the context of inner tracking or vertexing requirements for the LHC experiments.

During the latest decade, experiments have been performed at the CERN SPS to investigate the use of high-energy channeled nuclei in bent crystals for extraction, beam splitting and beam bending. An understanding of channeling in a bent crystal with extraction and de ̄ection eciencies for di€erent energies, crystal types and ions has been developed. Furthermore, the long-standing question of rad...

We report in this paper an investigation on radiation damage in 20 cm long BGO crystals produced at SIC as well as 20 cm long PWO-II crystals produced at BTCP for the proposed Panda experiment at GSI. The optical and scintillation properties of BGO and PWOII crystals, such as transmittance, light output and light response uniformity, were measured before and after γ-ray irradiations at differen...

2014 A very simplified description of angular distribution hyperfine interaction techniques is given, with a view to presenting their applications in ion-implantation studies of metals. Some typical experiments are reviewed. The latter part of the paper is devoted to a discussion of radiation damage effects in hyperfine interaction studies after ion-implantation.
