3. Adult Persons with Intellectual Disabilities on the Island of Ireland

Author

McConkey, R., Mulvany, F., and Barron, S.

Abstract

Background: Information on the numbers of adult persons (aged 20 years and over) with intellectual disability (ID) is rarely collated at a national level. This is an impediment to service planning especially for a changing population. Methods: A database of all persons in receipt of ID services has been operating in the Republic of Ireland since 1995. In Northern Ireland, regional databases can be used to provide similar information. Results: A total of 25,134 persons were known to services in 2002; an overall prevalence for the island of 6.34 per 1000. However this rate varied for different age groupings and across the two parts of the island. General population characteristics, as well as service factors, appear to account for this. Significantly more people lived with family carers in Northern Ireland. By 2021, it was estimated that the population would increase by over 20% with around one-third of persons aged over 50 years. Conclusions: These data illustrate the variations that exist in the numbers of adult persons with ID known to services across and within regions of a country. Hence caution must be exercised in extrapolating prevalence rates derived in one area to another. The availability of comparative national data highlights issues around the equitable funding and delivery of services.

Abstract

We describe the energy and sequence of phase transformations in multilayered Al/Zr foils with atomic ratios of 3 Al:1 Zr during low temperature (<350 °C) heat treatments in a differential scanning calorimeter. The initial phase formed is an Al-rich amorphous phase that appears to grow by Zr diffusion through the amorphous phase. The subsequent nucleation and growth of tetragonal Al3Zr along the Al/amorphous layer interface is mediated by Al diffusion through the crystalline intermetallic phase. Diffusion coefficients associated with these processes are higher than expected from reports of diffusivities measured at higher temperatures. The inferred heat of formation of the tetragonal Al3Zr phase is 1240 ± 40 J/g (53 ± 2 kJ/mol atom). No anomalous variation in the energy or sequence of phase transformations is found with bilayer thickness for samples with bilayer thickness in the range of 17 nm to 90 nm despite anomalies in the bilayer dependence of self-propagating reaction velocities in the same foils.

30. Self-propagating reactions in Al/Zr multilayers: Anomalous dependence of reaction velocity on bilayer thickness.

Abstract

High temperature, self-propagating reactions are observed in vapor-deposited Al/Zr multilayered foils of overall atomic ratios 3 Al:1 Zr and 2 Al:1 Zr and nanoscale layer thicknesses; however, the reaction velocities do not exhibit the inverse dependence on bilayer thickness that is expected based on changes in the average diffusion distance. Instead, for bilayer thicknesses of 20-30 nm, the velocity is essentially constant at ∼7.7 m/s. We explore several possible explanations for this anomalous behavior, including microstructural factors, changes in the phase evolution, and phase transformations in the reactant layers, but find no conclusive explanations. We determine that the phase evolution during self-propagating reactions in foils with a 3 Al:1 Zr stoichiometry is a rapid transformation from Al/Zr multilayers to the equilibrium intermetallic Al3Zr compound with no intermediate crystalline phases. This phase evolution is the same for foils of 90 nm bilayer thicknesses and foils of bilayer thicknesses in the range of 27 nm to 35 nm. Further, for foils with a bilayer thickness of 90 nm and a 3 Al:1 Zr overall chemistry, the propagation front is planar and steady, in contrast to unsteady reaction fronts in foils with 1 Al:1 Zr overall chemistry and similar bilayer thicknesses.

31. Studying exothermic reactions in the Ni-Al system at rapid heating rates using a nanocalorimeter.

Abstract

Heats of reaction and heat capacity changes were measured using scanning nanocalorimetry for a nickel and aluminum bilayer where initial heating rates of 104 K/s were achieved. Multiple exotherms were observed on the initial heating, but the number of intermediate exotherms decreased with increasing heating rate. The final phase was the B2 NiAl intermetallic. Results from the nanocalorimeter were compared with a conventional differential scanning calorimeter (operating at 0.7 K/s) to understand the effect of significant (10 000×) increases in heating rate on the phase transformation sequence. The high heating rate in the nanocalorimeter delays reaction initiation, causes the exothermic peaks to shift to higher temperatures, and appears to suppress the formation of intermediate, metastable phases. Potential explanations for this apparent suppression are discussed. [ABSTRACT FROM AUTHOR]

Abstract

We report on intermetallic formation reactions in vapor-deposited multilayered foils of Ni/Zr with 70 nm bilayers and overall atomic ratios of Ni:Zr, 2 Ni:Zr, and 7 Ni:2 Zr. The sequence of alloy phase formation and the stored energy is evaluated at slow heating rates (∼1 K/s) using differential scanning calorimetry traces to 725 °C. All three chemistries initially form a Ni-Zr amorphous phase which crystallizes first to the intermetallic NiZr. The heat of reaction to the final phase is 34-36 kJ/mol atom for all chemistries. Intermetallic formation reactions are also studied at rapid heating rates (greater than 105 K/s) in high temperature, self-propagating reactions which can be ignited in these foils by an electric spark. We find that reaction velocities and maximum reaction temperatures (Tmax) are largely independent of foil chemistry at 0.6±0.1 m/s and 1220±50 K, respectively, and that the measured Tmax is more than 200 K lower than predicted adiabatic temperatures (Tad). The difference between Tmax and Tad is explained by the prediction that transformation to the final intermetallic phases occurs after Tmax and results in the release of 20%-30% of the total heat of reaction and a delay in rapid cooling.

Abstract

We describe the deposition of insulating tantalum oxide thin films under conditions of controlled ion bombardment, which can be achieved using reactive sputtering on 90° off-axis substrates with an applied substrate bias. Capacitive measurements of Ta2O5 deposited on unbiased off-axis substrates indicate low frequency dielectric constants as high as [variant_greek_epsilon]r∼300. Low frequency loss tangents are high, tan δ>0.5, and have a pronounced frequency dependence. Deposition of the film off-axis with sufficient applied rf bias to the substrate (negative bias >-70 V) recovers the on-axis properties typical of Ta2O5, e.g., [variant_greek_epsilon]r∼22 and tan δ∼0.02. The recovery of normal dielectric behavior is attributed to the ion bombardment of the growing film under substrate bias, similar to on-axis depositions but absent from depositions on off-axis substrates with no applied substrate bias. We suggest that insufficiently bombarded films develop a Maxwell–Wagner type polarization along columnar voids. The void structure and the associated dielectric response vary with distance from the sputtering source due to variations in ion density and angle from the sputtering source. A similar dielectric response is observed in depositions on on-axis substrates as a function of angle from the central sputter gun axis. Our results suggest that ion bombardment is necessary for good quality sputtered dielectric films but that a controlled Ar+ flux is essentially equivalent to the uncontrolled O2-/O2- flux of on-axis reactive sputtering.

Abstract

Research has shown the benefits of Early Supported Discharge (ESD) from stroke units on patient outcomes as well as reducing bed days in hospital. This six month project identified that there are higher numbers of patients (12%) who could go home earlier from the hyper acute stroke unit via ESD services when there was an ESD coordinator role in place. In order for this to occur however there needs to be closer inter professional working relationships with social services in regards to ensuring that both patient health and social needs are met. This role could potentially increase the amount of appropriate patients being discharged to ESD teams thus allowing access to evidence based care. This short report describes how appropriate coordination can meet patient needs whilst saving the local stroke health economy over £230 000 in a 6 month period.
