Open source and accessibility: advantages and limitations

In this paper we discuss the open source process as it relates to accessibility software. Open source is a development model that has shown considerable benefits in a number of application areas. However the nature of accessibility tools and the intended users of such software products raise issues that must be addressed by the developer before users encounter the tools in real world contexts. In this paper we discuss the nature of the open source process, how it functions, and the motivations with regards to participation that developers self-report. We then explain the impact of these elements of the open source process as they relate to adaptive accessibility software. We use some specific examples of issues raised from the adoption of open source via a discussion of the ACCESS Framework, an accessibility engine designed to provide cross-platform accessibility support through plug-ins

What Musculoskeletal (MSK) Conditions are Referred from Routine General Practice (GP) and what Impact does this have on Developing Innovative Care Models for Patients with MSK Conditions in Primary Care?

Introduction: The current ethos within the United Kingdom (UK) health system is to encourage community management of health problems, increasing primary care workload. Yet General Practice (GP) is currently in ‘crisis’ with significant workload pressures. GP Federations have been developed to allow more collaborative working between GP practices and help develop new innovative models of care to better manage the GP workload pressures. Musculoskeletal(MSK) conditions constitute approximately 20% of General Practice(GP) consultations and therefore the Belfast GP Federation aimed to assess the demand for MSK conditions to allow development of new primary care-based treatment pathways for these conditions. The aim of this paper is therefore to assess the demand for orthopaedic, rheumatology and chronic MSK painful conditions by assessing the referrals from 2 GP practices and the referrals to one orthopaedic Integrated Clinical Assessment and Treatment services (ICATs) clinic for these conditions and then propose innovative models of care to manage this demand within the community. Methods: Secondary care referral rates for two urban GP surgeries in the Belfast area were assessed in April, 2016 to orthopaedics, rheumatology and chronic pain clinics. The referrals to an orthopaedic ICATs clinics, staffed by one GPwSI in MSK, in May 2016 were also reviewed. The orthopaedic ICATs team receive referrals from GPs regarding musculoskeletal conditions and this particular service is based in the Southern Trust area of Northern Ireland. Results: Overall from the 2 GP surgeries there was 59 orthopaedic referrals, 11 to rheumatology and 3 to the chronic pain clinic. The commonest joint referred to the orthopaedic clinic was knee (15 referrals, 25.4%) and the commonest reason to refer to rheumatology was to exclude an inflammatory arthritis (6 referrals, 54.5%). There was then 25 referrals to ICATs, with the commonest reason for referral being neck (6 referrals, 24%) and back (4 referrals, 16%). The commonest treatment options employed within the ICAT service included joint injections (8 patients, 32%) with referral to in-house physiotherapy (8 patients, 32%). Conclusions: UK GP is currently under significant workload pressures and musculoskeletal conditions, including orthopaedic, rheumatology and chronic painful conditions, make up a significant proportion of this workload. The main musculoskeletal areas which GPs are referring to secondary care include knee and spinal conditions. To help better manage this workload within primary care we propose developing a new community-based monthly musculoskeletal clinic based within local GP surgeries, supported by a MSK educational programme open to all GPs in the area. Outcomes which will be monitored from this quality improvement work will include secondary care referrals and maintaining high patient satisfaction as well as improving GP confidence in managing MSK conditions

Thermal Dispersion Model of Water Cooling Pltgu Cilegon Ccpp Discharge Into Margasari Coastal Waters at the Western Coast of Banten Bay

Thermal dispersion model based on the hydrodynamics model was applied on PLTGU Cilegon (electric power industry based on gas and steam) at the coast of Margasari, Pulo Ampel District, Serang-Banten. This PLTGU used around 60.000 mP3P/hour of seawater as cooling water system. Therefore, it produced water with high temperature of about 5 PoPC higher than the sourounding of seawater temperature. This high water temperature was flowed out into the coastal waters. This study tried to predict their distribution according to southeast and northeast monsoon. Model verification was conducted both to hydrodynamics component (tide and current) and water temperature. The verification results show good enough patterns between the model results and field measurement

Surface Energy in Cold Asymmetrical Fermion Superfluids

We derive the energy of the surface between the normal and superfluid components of a mixed phase of a system composed of two particle species with different densities. The surface energy is obtained by the integration of the free energy density in the interface between the two phases. We show that the mixed phase remains as the favored ground state over the gapless phase in weak coupling. We find that the surface energy effects emerge only at strong coupling.Comment: 12 pages, 2 figures, typos corrected, published versio

Phase Transition in Asymmetrical Superfluids I: Equal Fermi Surfaces

In this paper, we study phase transitions in asymmetrical fermion superfluids. In this scenario, the candidates to form pair are particles with mismatched masses and chemical potentials. We derive an expression for the critical temperature in terms of the gap and masses (or chemical potentials) when the constraint of equal Fermi surfaces $m_a\mu_a = m_b\mu_b$ is imposed.Comment: RevTex, 11 pages, 2 figures, typos corrected and an appendix added, accepted for publication in Phys.

Phase separation in asymmetrical fermion superfluids

Motivated by recent developments on cold atom traps and high density QCD we consider fermionic systems composed of two particle species with different densities. We argue that a mixed phase composed of normal and superfluid components is the energetically favored ground state. We suggest how this phase separation can be used as a probe of fermion superfluidity in atomic traps.Comment: 9 pages, LaTeX2e, version to appear in Phys.Rev.Let

Quantum normal-to-inhomogeneous superconductor phase transition in nearly two-dimensional metals

In multi-band systems, electrons from different orbitals coexist at the Fermi surface. An attractive interaction among these quasi-particles gives rise to inter-band or hybrid pairs which eventually condense in a superconducting state. These quasi-particles have a natural mismatch of their Fermi wave-vectors, $\delta k_F$, which depends on the strength of the hybridization between their orbitals. The existence of this natural scale suggests the possibility of inhomogeneous superconducting ground states in these systems, even in the absence of an applied magnetic field. Furthermore, since hybridization $V$ depends on pressure, this provides an external parameter to control the wave-vectors mismatch at the Fermi surface. In this work, we study the phase diagram of a two-dimensional, two-band metal with inter-band pairing. We show that as the mismatch between the Fermi wave-vectors of the two hybrid bands is reduced, the system presents a normal-to-inhomogeneous superconductor quantum phase transition at a critical value of the hybridization $V_c=\Delta_0$. The superconducting ground state for $V<V_c$ is characterized by a wave-vector with magnitude $|\mathbf{q}_c|=q_c=2 \Delta_0/\bar{v}_f$. Here $\Delta_0$ is the superconducting gap in the homogeneous state and $\bar{v}_f$ the average Fermi velocity. We discuss the nature of the quantum critical point (QCP) at $V_c$ and obtain the associated quantum critical exponents.Comment: 6 pages, 4 figure
