Purpose
This study aims to explore the environmental health role in meeting the housing condition, adaptation and associated needs of older people living in private sector housing in London, including those living with and at risk of dementia.


Design/methodology/approach
A multi-method approach was adopted. First, relevant public-facing websites in London were scrutinised. Second, a Qualtrics online survey was designed and circulated to capture relevant information around relevant services offered. Third, seven face-to-face interviews were conducted with front-line practitioners involved in providing housing services to private sector owners and tenants. These were transcribed verbatim and analysed using NVivo software before categorising into themes arising.


Findings
An erratic picture emerged around the meaning of "older people" and the services offered. A mixture of organisational arrangements and types of assistance available was reported, with different ways of access and referral to services, with a range of discretionary grants offered including for dementia. Some local authorities offered minimal specialist services, with others providing highly integrated and client-led, flexible interventions to meet a range of needs. Limited inclusion of research, evidence and evaluation of the effectiveness of interventions was reported overall, although client feedback was noted as good where services were provided.


Originality/value
There is very little published around environmental health work in supporting older people living in London and their housing, health and social care needs. This paper captures a snapshot of current and proposed services offered across London for owner-occupiers and private sector tenants, as a basis for further research for evidence-based, effective front-line services going forward.

The second edition of Environmental Health and Housing has been completely updated to cover the contemporary issues in public health that have emerged in recent years. With a theory and practice approach to public health, this edition focuses more on population health, health protection and improvement, and inter-agency approaches to effective intervention in housing and health through evidence-based practice. It provides the ideal introduction to the area, covering policy and strategy in housing, housing and inequality, housing inclusion, and the public health agenda. It provides a renewed focus on research into evidence-based housing and health issues, which have become subjects of growing international interest in recent years. This edition includes more case studies, reflection, and a greater emphasis on wider living environments. It also includesmajor pieces of new legislation, most notably the Housing Act 2004and theHousing and Planning Act 2016, as well as related regulations.

Purpose
– The purpose of this paper is to consolidate policy, research, evidence and good practice around strategies tackling fuel poverty and affordable warmth for older people aged over 60 to support the development of more effective services for this life course stage and to tackle physical and mental health inequalities.


Design/methodology/approach
– The authors consolidate current policy, research, evidence and examples of good practice in exploring effective interprofessional approaches that contribute to affordable warmth for older people through "desktop analysis". The authors support this with qualitative data from Health and Wellbeing Boards (HWBs), health inequalities and environmental health from research comprising four longitudinal case studies in the Midlands and North of England over 18 months and semi-structured interviews with members and support officers. A total of 50 interviews were undertaken and 55 hours of HWB meetings observed.


Findings
– There are numerous older people living in fuel poverty. The depth of fuel poverty increases with age particularly the over 75s and physical and mental ill health are affected. There are an increasing number of tools to help estimate health care costs around the cost effectiveness of interventions and there is a real need for more local evidence about what is working well, how and why. However, there is no mandatory requirement for fuel poverty strategies and more creative local strategies are required taking organisational and interprofessional relationships into account. The emphasis in integrated care provides new impetus and scope to encourage preventative services but these new partnerships need to be effective in what is a complex policy environment. There is still a long way to go in places. The challenges of ageing are numerous, complex and not fully understood and sit across multiple policy areas.


Originality/value
– Fuel poverty strategies tend to be delivered on a geographical or income bases rather than by life course approach and a focus on older people. We need to focus more specifically on older people, a rapidly growing population and to better understand thermal properties of our ageing housing stock and how best to intervene to protect and improve health and safety. Emerging approaches need to overcome artificial statutory and non statutory divides and move towards sustainable, evidence based affordable warmth strategies for older people to protect and improve health.

There has been renewed recognition that proactive strategies and interventions can address the social determinants of health, and the environmental health profession is well placed to effect positive change in many of these determinants. This qualitative research has revealed differences in the perceptions, experiences, and understandings of evidence-based practice among public health professionals from different backgrounds across different services in health care and local government in England. The absence of a strong tradition of evidence-based practice in environmental health appears to be a disadvantage in securing funding and playing a full role, as it has become the expectation in the new public health system. This has, at times, resulted in tensions between professionals with different backgrounds and frustration on the part of environmental health practitioners, who have a tradition of responding quickly to new challenges and "getting on with the job." There is generally a willingness to develop evidence-based practice in environmental health; however, this will take time and investment.

This paper investigates by an energetic approach possible new configurations of aircrafts, which can rival in low speed operations against helicopters. It starts from an effective energy balance of helicopters during fundamental operations: takeoff, horizontal flight, hovering, and landing. The energy state of a helicopter can be written as: E = ½ mV2 + mgh + ½ I ω2 (1) where m is mass of helicopter, I is total rotor inertia, ω is rotor rotational speed. By taking the partial derivative with respect to time of equation 1, the power is expressed as dE/dt = ΔP = mV dV/dt + mg dh/dt (2) By optimizing the energy balance of the helicopter a new aircraft configuration has been obtained that allow a very high lift even at very low speed, but drastically reducing the energy consumption during horizontal flight. The total power required is obtained by rotor power and overall efficiency factor (η) and HPreq total = η HPreq rotor. By equations (1) and (2) it has been produced a preliminary optimization in different operative conditions considering a speed range from 0.5 (hovering conditions) to 50 m/s. By an accurate balance of the results, it has been identified that the most disadvantageous situation for a helicopter is forward flight. A new powered wing architecture has been specifically studied for replicating the behaviour of helicopters. Preliminary it has been defined by starting from the energy equations the main characteristics of the propelled wing. From those numerical results it has been defined a new configuration of propelled wing and the new aircraft configuration which allow adequate performance against helicopter. Those wings take a large advantage of two not common features: symmetry with respect to a vertical axis and possibility of optimizing the shape for specific missions. It has been designed and optimized in different configurations by CFD. In particular, an accurate analysis of fluiddynamic of the system allows quantifying the different effects that allows realizing an extraordinary ratio between lift and thrust producing an effective vehicle that can rival against helicopter also at very low speeds with a morphing configuration that will be presented in the final paper because of patenting reasons. Results show that the proposed innovative aircraft configuration allows hovering and very low speed flight. In particular, the conditions and the design for this kind of operation are presented even if still in initial design stage. The presented aircraft architecture can also allow inverting the direction of motion just by inverting the direction of the thrust. In this case, it will allow overcoming completely the performances of helicopters. The energetic balance of flight has been evaluated and the advantages with respect to helicopters have been finally expressed with surprising results. ; The present work has been performed as part of the ACHEON Project | Acheon Project - Aerial Coanda High Efficiency Orienting-jet Nozzle project, with ref. 309041 supported by the European Union through the 7th Framework Programme (www.acheon.eu).

This paper analyses the ACHEON Coanda effect nozzle for aircraft propulsion, based on the dynamic equilibrium of two jet streams. The ACHEON concept, and, in particular, the HOMER nozzle, which is its main component, are presented, together with the literature milestones from which the idea originally stems. A subsystem analysis inspired by the principles of Constructal Theory is presented for the current architecture. A mathematical model of a 2D case of the system is developed, focusing on the combined effect of the mixing of the two streams and the Coanda adhesion over a convex surface. A validation of the model is also reported, based on 2D CFD analyses, under the hypothesis of incompressible flow. Results highlight that, in spite of its relative simplicity, the model produces accurate results. ; ACHEON Project | Acheon Project - Aerial Coanda High Efficiency Orienting-jet Nozzle project, with ref. 309041 supported by the European Union through the 7th Framework Programme

As a new alternative to tilting rotors or turbojet vector mechanical oriented nozzles, ACHEON (Aerial CoandaHigh Efficiency Orienting-jet Nozzle) has enormous advantages because it is free of moving elements and highly effective for Vertical/Short-Take-Off and Landing (V/STOL) aircraft. In this paper, an integrated flight/ thrust vectoringcontrol scheme for a jet powered Unmanned Aerial Vehicle (UAV) with an ACHEON nozzle is proposed to assess its suitability in jet aircraft flight applications. Firstly, a simplified Thrust-Vectoring (TV) population model is built based on CFD simulation data and parameter identification. Secondly, this TV propulsion model is embedded as a jet actuatorfor a benchmark fixed-wing 'Aerosonde' UAV, and then a four "cascaded-loop" controller, based on nonlinear dynamic inversion (NDI), is designed to individually control the angular rates (in the body frame), attitude angles (in the wind frame), track angles (in the navigation frame), and position (in the earth-centered frame) . Unlike previous research on fixed-wing UAV flight controls or TV controls, our proposed four-cascaded NDI control law can not only coordinatesurface control and TV control as well as an optimization controller, but can also implement an absolute self-position control for the autopilot flight control. Finally, flight simulations in a high-fidelity aerodynamic environment are performed to demonstrate the effectiveness and superiority of our proposed control scheme. ; Project ACHEON with ref. 309041, supported by European Union through the 7th Framework Program

An entropic wall with circulating water inside could be a solution for acclimatizing a new building with high-energy efficiency and high levels of internal comfort. If circulating water is thermally stabilized by exchanging in the ground such has it happens in geothermal plants, a thermal shield could be realized keeping walls in comfort conditions and minimizing energy needs for further temperature regulations. This paper presents optimization guidelines of such a wall with the objective of maximizing the performances of the wall for reaching optimal internal wellness conditions. Optimization has been realized by a constructal law based method, which has been personalized by a step-by-step process and has been named constructal design for efficiency (CDE). The optimization of the system has been produced at different levels. It starts from a preliminary analysis at system levels, which allow defining the best objectives that could be reached. After this preliminary process, the system has been divided into modules, and the critical ones which have higher influence on the performances of the system have been evaluated. This analysis has been coupled also with an industrial analysis with the goal of defining an effective layout, which could be also manufactured with acceptable costs. The result has produced a final solution with a very good compromise between energetic performances and minimization of costs at industrial level. The results open interesting perspectives for the constructal law to become the core of an effective methodology of an industrial design which can couple perfectly with the modular approach which is currently the major part of industrial companies. ; ACHEON Project | Acheon Project - Aerial Coanda High Efficiency Orienting-jet Nozzle project, with ref. 309041 supported by the European Union through the 7t

AbstractThe World Health Organization has declared antibiotic resistance "one of the biggest threats to global health." Mounting evidence suggests that antibiotic use in industrial‐scale hog farming is contributing to the spread of antibiotic‐resistant Staphylococcus aureus. To capture available evidence on these risks, we searched peer‐reviewed studies published before June 2017 and conducted a meta‐analysis of these studies' estimates of the prevalence of swine‐associated, antibiotic‐resistant S. aureus in animals, humans, and the environment. The 166 relevant studies revealed consistent evidence of livestock‐associated methicillin‐resistant S. aureus (MRSA) in hog herds (55.3%) raised with antibiotics. MRSA prevalence was also substantial in slaughterhouse pigs (30.4%), industrial hog operation workers (24.4%), and veterinarians (16.8%). The prevalence of swine‐associated, multidrug‐resistant S. aureus (MDRSA)—with resistance to three or more antibiotics—is not as well documented. Nonetheless, sufficient studies were available to estimate MDRSA pooled prevalence in conventional hog operation workers (15.0%), workers' household members (13.0%), and community members (5.37%). Evidence also suggests that antibiotic‐resistant S. aureus can be present in air, soil, water, and household surface samples gathered in or near high‐intensity hog operations. An important caveat is that prevalence estimates for humans reflect colonization, not active infection, and the health risks of colonization remain poorly understood. In addition, these pooled results may not represent risks in specific locations, due to wide geographic variation. Nonetheless, these results underscore the need for additional preventive action to stem the spread of antibiotic‐resistant pathogens from livestock operations and a streamlined reporting system to track this risk.
