Abstract
MAGNESIUM metal with its low density high strength and stiffness properties is a material which is used extensively in the Wessex helicopter for castings, forgings, and in sheet form in the skin stringer constructed fuselage. Extensive utilisation of these aircraft has shown that a corrosion hazard is present with this material in the fuselage application. Accidental damage, mis‐use and normal wear and tear removes the carefully applied organic protection permitting moisture to come into contact with the non‐protected metal, with the result that corrosive conditions are generated and it is found that in the non‐accessible areas, intensive corrosion damage occurs and it is not discovered in time for remedial action and the efficiency of the structure and airframe is impaired.

ESTABLISHING A STANDARD SOME twenty‐two years ago Dr de Bruyne invented the Redux system for joining metal to metal in a manner suitable for use in aircraft construction The phenol‐formaldehyde/polyvinyl‐formal formulation of this system is still widely used today. What is it that has made this system such a success through the years?

Abstract
hydrolysis can be described as the reaction between water and another material in which a definite chemical change occurs. Materials which do not react with water can be said to possess hydrolytic stability. Polyurethanes can be hydrolysed by water under certain conditions and the chemical changes involved result in a deterioration in properties of the material. These changes can be followed chemically or physically but under severe conditions the degradation is readily apparent. In these cases the polyurethane can change from being a tough elastic material to a soft plastic substance with little or no strength.

Abstract
THE mechanical properties of 112 nominally identical glass reinforced laminates prepared by four different organisations have been determined. A statistical analysis of the results investigated the effect of variability in the raw materials and laminating techniques. It was concluded that the total variability was approximately 7 per cent.

Abstract
In this chapter we discuss the dynamics of convergence-divergence between organic and non-organic farming systems. We are specifically interested in how and in what ways organic systems emerge into a new system that synthesizes the diverse qualities of competing systems. Or, will these systems continue to diverge because of their path dependencies and contradictory, unresolvable logics? Alternatively, are we confronted with conversion? Following a discussion of the origin of organic agriculture and the IFOAM Principles, we explore differentiation of two agricultural paradigms that was developed more than 20 years ago before the rise of GMOs. This comparison identifies the key features of both systems and a first interpretation on the potential of convergence-divergence. Third, we take a macro-look at agro-food chain that offers insights on the convergence-divergence potential in the context of global, economic, market, political, and societal dynamics. Fourth, we discuss convergence-divergence at the production level comparing the four agricultural systems. Finally, we reflect and assess on the explanatory potential of our study for the future development of organic and non-organic agriculture/farming. We conclude that there is more evidence for conversion than for convergence.

Abstract
The focus of this chapter is drawn from the author’s lived experience and background as a third generation stateless Palestinian refugee who lived in one of the Palestinian camps in Lebanon and inherited the refugeeship from her parents and grandparents. Even though the author agrees with Hannah Arendt (1943) that ‘We don’t like to be called refugees’ (p. 264), the process of this research and thoughts behind it are attributed to the author’s personal experiences, as Arendt (1964) confirms in her statement that the process of thought can seldom be possible without being attributed to a personal experience.

Abstract
Purpose
Resilience is an increasingly important concept that contributes to sustainability and wellbeing of a community. Asset-based community development (ABCD) may offer promising approaches to boosting community resilience in Australia, especially within marginalised groups.
Design/methodology/approach
A scoping review was conducted to conceptualise existing literature on ABCD approaches to building resilience. Research databases were searched with relevant details.
Findings
Thirty-three sources were identified as meeting the inclusion criteria and were reviewed in terms of six themes: integration and identity, health, mental health, education, employment and community planning. Issues identified by the literature within these themes can be alleviated through asset-based approaches. Implications for planning of asset-based programs and policy change are discussed in light of the findings.
Practical implications
The results of this study provide several implications for practise, policy recommendations and future research into this area. Results suggest that increasing capacity around asset-based coping mechanisms, such as support networks through religious and cultural groups, would promote community development and foster resilience. Furthermore, policy on refugees in multiple areas, such as psychological service provision and employment, should be redesigned in a way that acknowledges their complex and diverse needs and facilitates their integration into the community. Though multiple ways to achieve this goal have been explored in literature, a sustained and broader approach is necessary to see widespread change. Further research and funding are required to explore and implement appropriate responses. Based on the findings and discussion above, the authors make the following policy recommendations. Service providers need to be aware of and incorporate culturally appropriate programs in the areas of mental health assessment and intervention, education and employment. The trauma-informed approach should be used when dealing with refugee groups and other groups who have faced hardships. Government policy should focus on improving community engagement to create and strengthen social networks, which are vital in boosting integration into the community and increasing health education and access to services. Government should focus on asset-based approaches in designing education and employment integration programs to promote social belonging and community engagement, and thus, community resilience, which will consequently have beneficial individual and group outcomes. The current governmental policy surrounding refugees should be overhauled with the goal of successful refugee integration in mind, such as incorporating the ability for refugees to access vital services such as employment and skills transferability programs. Due to current policy, these services are inaccessible to a large portion of refugees, hindering their integration. Government needs to create specific guidelines for the provision of psychological services to refugees to improve the quality of mental health services available to this group.

Abstract
Purpose
Building the resilience of children with intellectual disabilities (ChID) can help reduce the personal, social and economic costs associated with mental ill health among such children. The purpose of this paper is to review the research evidence on resilience in ChID and to suggest areas for further research.
Design/methodology/approach
Journal articles published in the last 20 years were searched in on-line databases to find potential papers for this review. The inclusion criteria were to search for published journal articles covering the theme of resilience in ChID and their families. All identified titles and abstracts were screened which resulted in 50 articles. These were scrutinised more thoroughly and 34 remaining articles were selected for review.
Findings
Resilience is a dynamic process involving interactions between various risk and protective processes both internal and external to the individual that act to mediate the influences of adverse life events. Five key themes were identified within the literature which helped to form a picture of the current understanding of resilience among ChID and their careers. These were increased risk factors associated with ID, the role of personal attributes on resilience, family and resilience, schooling and resilience, and cultural factors which enhance resilience.
Originality/value
Despite the consistency with which poor outcomes for ChID have been reported there is little investigation of the specific causes, contributory factors and processes that might improve them. This paper contributes to greater understanding of resilience factors for children and young people with ID and provides areas for further research.
