Older People Have Their Say! Survey of Older People’s Needs in Westgate Ward, Canterbury

Although a lot of effort in the last few years has been made to address the needs of people in old age, surprisingly not much is known about the views of this age group in the Canterbury City Council area. To address this lack of knowledge, the Canterbury and District Pensioners’ Forum was funded by the Canterbury City Council to explore the needs of older people living in this area. Our Forum decided to collaborate with the University of Kent to produce a survey on the needs of older people within the District of Canterbury. During the process of the project, we decided to base the survey on the Westgate Ward in Canterbury because we felt that older people living in this area represent a good example for highlighting needs that involve ‘ordinary’ older people. This ward is quite diverse in many ways; it spreads from a semi-rural area through to town dwelling. It is not seen as an area of deprivation, thereby has not generated any special money from the Government to help with social problems in the provision of social centres, community learning, social activities etc. Yet we know from our own experience that what may appear in many parts as fairly affluent is quite deprived of places for people to meet; and has large public housing areas with no amenities at all. The present Government put through legislation, which said that public services should be surveyed, and the part of that legislation that we are particularly interested in is “The National Service Framework for Older People”. That framework asks that older people are treated with dignity by NHS and Social Care organisations; and that Councils –County and District, examine existing services- housing, leisure and transport – to identify opportunities to promote health and well-being. We felt that Westgate Ward would be representative of many other areas within our District that had not received any special investment. The work that has been done in producing this survey has been done by members of the Canterbury & District Pensioners’ Forum with help from the University of Kent. It is a survey of older people, carried out by older people. It is our work. Information generated by this project will be assisting the Forum’s work to promote important issues related to older people’s quality of life and access to health and social care services. A comment from J.F. Kennedy we believe sums up the approach that we took at the start of this survey: “It is not enough for a nation to have added years of life. Our object must be to add new life to those years

A 360 degree approach to resolving uncertainty and prioritising delivery of coastal adaptation, resilience and environmental protection for the future economic growth of Jersey, Channel Isles

The island of Jersey has a rich history influenced by natural and man-made change; particularly the fortifications constructed as defensive structures during periods of conflict, from the Napoleonic period through to 1940’s. Over the next century Jersey faces a growing challenge from the predicted impacts of climate change via rising sea levels combined with increasingly intense rainfall which will result in an increase to the extents of coastal and pluvial flooding. Jersey needs to be prepared and resilient; to support a digital Island that attracts international business, providing a secure and safe location. Jersey’s shoreline policies balance the Island’s environmental legislation and economic policies, but a priority for the Government is flood avoidance, mitigation and development opportunities through planning policy and asset adaptation in a way that supports the Island’s prosperity. This includes consideration of advancing the ‘defence’ line. A 360 degree approach is taken to deliver an island wide coastal resilience plan, which includes pluvial flooding as well as coastal flooding – the outcome will be the Jersey Shoreline Management Plan (SMP). This paper presents the first ever emerging coastal flood and erosion mapping for the whole island under the jurisdiction of the Government of Jersey. The mapping is supported by shoreline planning and policy over the next 20, 50 and 100 years, which augments the plan for integrated coastal management based on the Government’s environmental, community and economic objectives for the island

The effects of an additive on the release of potassium in biomass combustion

This study focuses on the effects of an aluminosilicate additive on the fate of potassium during biomass combustion. Such additives have shown some success in mitigating slagging and fouling problems in boilers and furnaces, and the mobility of potassium in combustion systems is one of the key factors dictating ash behaviour. To investigate this, a flame emission spectroscopy technique was used to evaluate the differences in the gas-phase potassium release profiles during the combustion of 5 mm diameter pellets of different biomass suspended in a methane-air flame. The biomass pellets were evaluated with various mixes of an aluminosilicate based additive (5, 15 and 25 wt%). Potassium emission detection, coupled with high speed video of the combustion process, indicated that potassium evolves over the three stages of volatile combustion (a sharp peak in the emission profile), char combustion (a broader peak) and “ash cooking” (a very broad peak over an extended period, long after the end of combustion). In the absence of additive, the three biomass studied (softwood, wheat straw, olive residue) behaved quite differently in terms of potassium release profiles. When the results are normalized for the amount of potassium in the fuel, it is clear that a large fraction of potassium enters the gas phase during the volatile and char combustion of the softwood. Olive residue, releases a lower fraction of potassium during the volatile and char combustion stages, indicating that more potassium is fixed in the ash. In contrast, wheat straw shows a release of potassium during combustion, and then, after a period of “ash cooking”, a substantial gradual release with continued exposure to hot combustion gases. The difference in the emission profiles can be interpreted in terms of the K:Cl ratios and the K:(Si+Al) ratios: high chlorine and/or low (Si+Al) facilitates the release of KCl or KOH to the gas phase, while high (Si+Al) helps to fix K in the solid phase. The addition of the aluminosilicate additive shows a clear reduction in the potassium released from all the biomass pellets, particularly during the char-oxidation and “ash cooking” stages, and the level of additive required is related to the amount of K in the biomass. The potassium emission experiments were complemented by laboratory-scale preparation of ash at different temperatures, and detection of residual potassium in the ash using Atomic Absorption Spectroscopy (AAS). These results validated the findings and quantified the higher fractions of potassium retained within the ash when additives are used. For the wood ash 70-100% of K is retained in the ash in the presence of additive; for the wheat straw, this figure is 60-80% and for the olive pellets it is 70-100%

Prognostic limitations of donor t cell chimerism after myeloablative allogeneic stem cell transplantation for acute myeloid leukemia and myelodysplastic syndromes

Donor T cell chimerism is associated with relapse outcomes after allogeneic stem cell transplantation (alloSCT) for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). However, measures of statistical association do not adequately assess the performance of a prognostic biomarker, which is best characterized by its sensitivity and specificity for the chosen outcome. We analyzed donor T cell chimerism results at day 100 (D100chim) after myeloablative alloSCT for AML or MDS in 103 patients and determined its sensitivity and specificity for relapse-free survival at 6 months (RFS6) and 12 months (RFS12) post-alloSCT. The area under the receiver operating characteristic curve for RFS6 was .68, demonstrating only modest utility as a predictive biomarker, although this was greater than RFS12 at .62. Using a D100chim threshold of 65%, the specificity for RFS6 was 96.6%; however, sensitivity was poor at 26.7%. This equated to a negative predictive value of 88.5% and positive predictive value of 57.1%. Changing the threshold for D100chim to 75% or 85% modestly improved the sensitivity of D100chim for RFS6; however, this was at the expense of specificity. D100chim is specific but lacks sensitivity as a prognostic biomarker of early RFS after myeloablative alloSCT for AML or MDS. Caution is required when using D100chim to guide treatment decisions including immunologic manipulation, which may expose patients to unwarranted graft-versus-host disease

Gas phase potassium release from a single particle of biomass during high temperature combustion

A notable characteristic of solid biomass fuels as compared to coal is their significantly higher potassium content. Potassium influences ash deposition and corrosion mechanisms in furnaces and boilers, the effects of which may differ depending on phase transformations of potassium species in the gas phase and condensed phase. An understanding of how potassium is released from biomass fuels during the combustion process is therefore useful for plant designers and operators assessing means of avoiding or mitigating these potential problems. An experimental method is used to measure release patterns from single particles of biomass fuels using flame emission spectroscopy and a single-particle combustion rig. The experimental arrangement also allowed simultaneous thermal imaging of the combusting particle in order to determine the surface temperature. A model of the single particle combustion is presented. Using experimental data on devolatilisation and burnout times for different sized particles and the measured surface temperature profiles, the thermal and kinetic sub-models are verified. A model for potassium release is described and this is integrated to the single particle combustion model to allow prediction of the temporal patterns of release of gas-phase potassium. The modelled release patterns were compared with those observed. Good agreement between modelled and measured potassium release patterns was attained confirming that the proposed mechanisms affecting potassium release are valid

The Maker\u27s CubeSat: Increasing Student-lab Capabilities in the Design, Integration & Test of the Alpha CubeSat

Alpha is a 1U CubeSat developed at Cornell University that deploys a ChipSat-equipped free-flying light sail into LEO. While the payload is rather unique, the spacecraft that deploys it is designed to be adaptable and scalable to future student-led missions. Technology demonstrations include a 3D-printed chassis, entirely commercial off-the-shelf (COTS) electronics, an Iridium modem that bypasses the need for ground-station hardware, and magnetorquer-only spin-stabilization and pointing. This paper details the driving factors behind Alpha’s novel architecture with a focus on the affordable methods developed for design verification and optimization. Drawing inspiration from the maker community, the lab acquired a suite of tools that dramatically increased in-house integration and test capabilities. Lessons are shared from training multiple generations of students on these tools, along with the best-practices developed for student assembly of flight hardware
