In real life, immediately after joint replacement, the artificial joint is actually bathed in blood (and clotted blood) instead of synovial fluid. Blood contains large molecules and cells of size ~ 5 to 20 μm suspended in plasma and considered to be a non-Newtonian (pseudoplastic) fluid with density of 1060 Kg/m³ and viscosity ~ 0.01 Pas at shear rates of 3000 s⁻¹ (as obtained in this work). The effect of these properties on friction and lubrication is not fully understood and, so far to our knowledge, hardly any studies have been carried out regarding friction of metal-on-metal bearings with various clearances in the presence of lubricants such as blood or a fluid containing macromolecules such as hyaluronic acid (HA) which is a major component of synovial fluid increasing its viscosity and lubricating properties. In this work, therefore, we have investigated the frictional behaviour of a group of Smith and Nephew Birmingham Hip Resurfacing implants with a nominal diameter of 50mm and diametral clearances in the range ~ 80 μm to 300 μm, in the presence of blood (clotted and whole blood), a combination of bovine serum (BS) with hyaluronic acid (HA) and carboxymethyl cellulose (CMC, as gelling agent) adjusted to a range of viscosities (~0.001-0.2 Pas), and bovine serum with CMC adjusted to a similar range of viscosities. These results suggested that reduced clearance bearings have the potential to generate high friction especially in the presence of blood which is indeed the in vivo lubricant in the early weeks after implantation. Friction factors in higher clearance bearings were found to be lower than those of the lower clearance bearings using blood as the lubricant. Similar trends, i.e. increase in friction factor with reduction in diametral clearance, were found to be also the case using a combination of BS+CMC or BS+HA+CMC as lubricants having viscosities in the range 0.1-0.2 and 0.03-0.14 Pas, respectively. On the other hand, all the lubricants with lower viscosities in the range 0.001-0.0013 and 0.001-0.013 Pas for both BS+CMC and BS+HA+CMC, respectively, showed the opposite effect, i.e. caused an increase in friction factor with increase in diametral clearance. Another six large diameter (50mm nominal) BHR deflected prostheses with various clearances (~ 50-280μm after cup deflection) were friction tested in vitro in the presence of blood and clotted blood to study the effect of cup deflection on friction. It was found that the biological lubricants caused higher friction factors at the lower diametral clearances for blood and clotted blood as clearance decreased from 280μm to 50μm (after deflection). The result of this investigation has suggested strongly that the optimum clearance for the 50 mm diameter MOM BHR implants to be ≥150μm and <235μm when blood lubricant used, so as to avoid high frictions (i.e. avoid friction factors >0.2) and be able to accommodate a mixed lubrication mode and hence lower the risk of micro- or even macro-motion specially immediately after hip implantation. These suggested optimum clearances will also allow for low friction (i.e. friction factors of <0.2-0.07) and reasonable lubrication (dominantly mixed regime) for the likely cup deflection occurring as a result of press-fit fixation.

Who is responsible for youth policy implementation? This thesis attempts to deepen our understanding of Swedish and Nordic youth policy. Youth policy is cross-sectoral and includes all the decisions and measures affecting the conditions of young people. National youth policy therefore concerns young people's life situations in a number of different areas, such as work, housing, education, health, leisure and influence. The purpose of the study is to increase the knowledge of youth policy work the last century by understanding the impact of youth research concerning adults' role in youth policy implementation.   A mixed method approach has been applied to the study: interviews, documents and youth theory have been analysed. The results show that youth research had a major impact on the Swedish youth policy. It also shows that the state has an important role in the implementation of youth policies. To create a youth policy that meets the democratic mandate, it is necessary to create a systematic approach and guidelines for municipalities. The study has clearly shown that the state's role in the democratic mandate differ significantly over time and that adults' role in the implementation is of great importance. The study draws attention to the perception of adults over time and how adults are increasingly seen as a barrier to young people's democratic schooling, and on what grounds this opinion rests. It is proposed that views on the democratic mandate will be extended from a municipal focus to the state where youth policy have a broader focus that takes account of national welfare goals based on a policy all municipalities has to be involved in.

Despite the upsurge in fact-based and verbatim theatre in recent years (Fogarth and Megson 2009: 1), engagement with the form as a technique equally suitable for poetry has been especially limited. This thesis examines the deployment of verbatim methods in a series of poems which constitute the creative element, written in order to (re)present expressions of identity and ideas of imagined community during the 2011 riots in Birmingham. Located in the context of this particular disorder, United We Stand explores both individual and group experiences of the events that took place in Birmingham. The series of verbatim poems draws on data extracted from 25 semi-structured, life-story interviews with participants who lived or worked in the city during these incidents. In doing so, both the thesis and the creative practice that informs it critique Benedict Anderson s earlier model of the nation as an imagined community (1983; 1991; 2006). While quantitative network analysis is deployed to establish the ties between media channels and ordinary citizens that were maintained online through social networking, creative and reported responses published by these same media sources are analysed in relation to national narrative conventions (Billig 2001; Mihelj 2011). This demonstrates that new and popular media played a significant role in (re)presenting imagined communities in this setting. By providing evidence for the existence of these shifting imagined communities across various geographical, social and cultural scales, the thesis suggests that Anderson s decision to focus on the nation is problematic. It argues that his framework is partial and that a new definition of imagined community as both fluid and emergent is necessary. Literary context for the thesis is found in the origins and developments of verbatim; exploring early documentary theatre practice and contemporary verbatim productions by Richard Norton-Taylor, Alecky Blythe, and Gillian Slovo. Through an analysis of Bhanu Kapil Rider s The Vertical Interrogation of Strangers (2001), the thesis illustrates how existing poets have organised comparable methods in their own work. This culminates in a demonstration of practice as research by producing a ground-breaking body of work: United We Stand is a series of poems crafted through the deployment of verbatim methods. The thesis demonstrates that deploying verbatim methods in poetry is suitable for (re)presenting expressions of identity and ideas of imagined community in this context. By transforming the voices of ordinary people of Birmingham, United We Stand reflects the media narratives that precede it: the poems are a direct engagement with the same fluid and emergent imagined communities that they argue existed. More importantly, though, this thesis goes beyond contemporary techniques of verbatim and establishes the evolutionary nature of it as a poetic practice. The combination of verbatim methods and visual-digital tools that I deploy throughout United We Stand results in a new creative process which I have termed Digital Poetic Mimesis.

In real life, immediately after joint replacement, the artificial joint is actually bathed in blood (and clotted blood) instead of synovial fluid. Blood contains large molecules and cells of size ~ 5 to 20 2m suspended in plasma and considered to be a non-Newtonian (pseudoplastic) fluid with density of 1060 Kg/m3 and viscosity ~ 0.01 Pas at shear rates of 3000 s-1 (as obtained in this work). The effect of these properties on friction and lubrication is not fully understood and, so far to our knowledge, hardly any studies have been carried out regarding friction of metal-on-metal bearings with various clearances in the presence of lubricants such as blood or a fluid containing macromolecules such as hyaluronic acid (HA) which is a major component of synovial fluid increasing its viscosity and lubricating properties.
