This chapter draws on 10 years of ethnographic fieldwork collected in gay bars from three American cities to explore the strategies LGBTQ subcultures deploy to recreate meaningful places within the vestiges of local queer nightlife. As gentrification and social acceptance accelerate the closures of LGBTQ-specific bars and nightclubs worldwide, venues that once served a specific LGBTQ subculture (i.e., leather bars) expand their offerings to incorporate displaced LGBTQ subcultures. Attending to how LGBTQ subcultures might appropriate designated spaces within a gay venue to support community (nightlife complexes), how management and LGBT subcultures temporally circumscribe subcultural practices and traditions to create fleeting, but recurring places (episodic places), and how patrons might disrupt an existing production of place by imposing practices associated with a discrepant LGBTQ subculture(place ruptures), this chapter challenges the notion of “the gay bar” as a singular place catering to a specific subculture. Instead, gay bars increasingly constitute a collection of places within the same space, which may shift depending on its use by patrons occupying the space at any given moment. Beyond the investigation of gay bars, this chapter contributes to the growing sociological literature exploring the multifaceted, unstable, and ephemeral nature of place and place-making in the postmodern city.

This study explores what it means to be a mission-driven arts organisation (MDAO) in the UK. Drawing on literature relating to artistic risk and rupture, mission and vision, and arts participation, the purpose of this paper is to shed light on how Slung Low, a theatre organisation with a core staff of five, creates large and complex initiatives and seeks to make a difference to its local community.

Using a case study approach, this interpretive study makes use of qualitative data to offer context-specific knowledge about how MDAOs create new initiatives including: interviews with members of the Slung Low team; attendance at company meetings; analysis of internal organisational documents, company website and artistic director’s blog; and articles about Slung Low from the local, national and theatre industry press. Data was gathered through a research collaboration with Slung Low which is supported by Paul Hamlyn Foundation.

The results offer fresh insight into how MDAOs take a positive approach to rupture and rapid change. The study finds that by embracing risk and committing to an ambitious and provocative mission, small-scale arts organisations can achieve artistic, cultural and social objectives which far exceed their size.

This paper offers an organisational perspective on the research questions and so participants were not interviewed on this occasion. However, the participant view will be the subject of further research with Slung Low.

This research paper provides insight into one of the UK’s most innovative theatre companies during a period of monumental change, and advances knowledge on mission-driven organisations by offering reflections on what it means to be an arts organisation which places rupture, risk and usefulness at the heart of its mission.

THE marked dependence of the strength of metals on temperature, and on rate of loading at high temperatures, can be explained by assuming that above the equi‐cohesive temperature rupture takes place by plastic flow in a non‐homogeneous medium, consisting of rigid crystallites weakly cemented together. Although the stress concentrations required by the Griffith theory must still be operative above the equi‐cohesive temperature, it is suggested that they produce intergranular flow, rather than the elastic separation that occurs at temperatures below the equi‐cohesive temperature. A theory is developed based on the assumption that the strain energy at rupture reduces the energy of activation of the flow process, and the theory is shown to be in numerical agreement with the experimental results, if the energy of activation of the flow process is about one seventh of the latent heat of evaporation per gram atom. Values of the cohesive strengths and of the stress concentration factors are also derived.

This study seeks to challenge the notions of the standardized care pathway and patient‐centred care, both of which provide only a partial view of care as a complex system. In exploring and contrasting the care pathway protocol and an actual care pathway, the study aims to analyze the conceptualizations of care that actors involved in the actual care pathway have. The study makes suggestions on how to expand care pathways and thereby improve patient care.

A care pathway protocol is contrasted with the actual care pathway of a patient at a university hospital in Finland. Observational ethnography is combined with a narrative approach and activity‐theoretical ideas.

The study depicts the gap between the care pathway protocol and an actual care pathway. The actual care pathway, rather than being a clear‐cut process, is ruptured and unpredictable. The conceptualizations of care (i.e. care‐objects) held by the doctors, nurses and the patient were fragmented and clashed in their practical work activity. The main message to hospital management is that in order to expand care pathways, the multiple care‐objects need to be placed in constructive interplay.

A single actual care pathway is presented and the results are interpreted accordingly.

The study explores the idea of a care pathway and patient‐centred care in the analysis of care‐objects. A new discursive model is introduced that places different care‐objects into interplay and opens up the possibilities for the expansion of care pathways.

The purpose of this paper is to address the problem of substitution of steel with fiber-reinforced polymer-matrix composite in military-vehicle hull-floors, and identifies and quantifies the associated main benefits and shortcomings.

The problem is investigated using a combined finite-element/discrete-particle computational analysis. Within this analysis, soil (in which a landmine is buried), gaseous detonation products and air are modeled as assemblies of discrete, interacting particles while the hull-floor is treated as a Lagrangian-type continuum structure. Considerable effort has been invested in deriving the discrete-material properties from the available experimental data. Special attention has been given to the derivation of the contact properties since these, in the cases involving discrete particles, contain a majority of the information pertaining to the constitutive response of the associated materials. The potential ramifications associated with the aforementioned material substitution are investigated under a large number of mine-detonation scenarios involving physically realistic ranges of the landmine mass, its depth of burial in the soil, and the soil-surface/floor-plate distances.

The results obtained clearly revealed both the benefits and the shortcomings associated with the examined material substitution, suggesting that they should be properly weighted in each specific case of hull-floor design.

To the authors’ knowledge, the present work is the first public-domain report of the findings concerning the complexity of steel substitution with composite-material in military-vehicle hull-floors.

The purpose of this paper is to evaluate advanced mathematical electrochemical noise analysis (ENA) as a way of corrosion monitoring for carbon steel.

The electrochemical potential/current noise was recorded simultaneously with a working‐reference‐working electrode set up and the processing of data was performed through fast Fourier transformation (FFT) and wavelet transformation (WT) routes. The formation and rupture of carbonate films on St37 steel electrodes in a 0.5 M sodium bicarbonate electrolyte was studied for 20 h utilizing an electrochemical noise approach.

Although the slope of mid‐range of noise impedance exhibited a mechanistic style, and increased with film formation and decreased with film rupture, FFT of potential noise was more sensitive to film formation and rupture. WT of potential noise depicted that ν=1.41 × 10⁻² Hz was the boundary frequency in the film formation. At frequencies higher than the mentioned limit, the fraction of distributed potential decreased with time. However, the opposite behavior was observed during the rupture of the film.

The preliminary results show that the proposed novel electrochemical method, wavelet and FFT ENA, is very able to monitor the corrosion behavior of carbon steel corrosion in carbonate media.

The purpose of this study is experimental research of the mechanical behavior of slab reinforced by cork composite patch submitted to an eccentric progressive compressive load applied to on impact rectangle of dimensions 28 × 23 cm². An analytical model and numerical modeling by finite elements are performed. This study is motivated by the evaluation of the effectiveness of this type of partial reinforcement to improve strength and ductility. The results are given by load-displacement curves, tensile damages cartography and ultimate strength histogram.

In experimental protocol, the following two parameters have been considered: the dimensions of the patch and the eccentricity of the load. The sections of the patches are calculated so that the ratio (XP/YP) patch is proportional to the ratio (LD/lD), with a step of 6 cm longitudinally and 4 cm transversely. Several dimensions patches are considered: (6 × 4) cm², (12 × 8) cm² and (18 × 12) cm². The eccentric punching loading test was performed with an eccentricity of the load (1/3) L’ and (2/3) L’ compared to the center of gravity of the slab. Taking into account the eccentricity of the load in estimating the rupture strength, the equations are developed. Thus, numerical simulations are carried, to extract tensile damages cartography.

The results show that the rupture begins with the appearance of cracks in the unreinforced area. For an eccentricity of 1/3L’, the best strength/section ratio is obtained for patch (12 × 8) cm², whereas for an eccentricity de 2/3L’, the patch (6 × 4) cm² gives a better resistance. The results highlight the influence of the composite on the ultimate load. The force-displacement relations are little modified in the elastic phase. The experimental results have been compared with the theoretical models showing a good correlation.

The strength and ductility are depended on the dimensions of the patch and the eccentricity of the load. The use of a patch to cover the most stressed area, in the event of an eccentric axial load is a very economical solution compared to the total reinforcement. The damage field shows that the evolution of cracks depends on dimensions and the position of the patch. Indeed, the eccentricity of the vertical load induces an additional bending moment that will influence the fracture surface. The rupture load and ultimate displacement increase with the surface of the patch.

The aim of this work is to check the influence of some sewing parameters upon the tensile behaviour of a textile assembly (assembly of two woven samples by a seam).

This analysis was carried out according to the approach “experimental design”. The studied parameters are the sewing thread, the stitch type, the stitch density, the needle size and the edge of seam. The targeted answers are drawn from the tensile test on the assembly: breaking strength, breaking elongation and deformation energy.

In order to highlight the behaviour of the seam, a load‐extension curve for the stitch line is established: it represents, for a value of a given tensile effort, the difference between the displacement of the assembly and that of the fabric. From this curve, breaking elongation as well as the deformation energy are determined.

An “experimental design” was carried out and analysed for two types of assembly (warp and weft). Linear models predicting each response were established.

Piston ring dynamic problem plays an important role in the lubricant characteristics of a reciprocating engine, which lead to engine wear and the increased consumption of lubricating oil. A cavitation analysis of the piston ring lubrication with two-dimensional Reynolds equation has rarely been reported owing to the complex working condition. The purpose of this study is to establish a precise model that can provide guidance for the design of the piston ring.

In this paper, a cavitation model and its effect on the piston ring lubrication was studied in a simulation program based on the mass-conserving theory which is solved by means of the Newton–Raphson method. In this study, some models such as mixed lubrication, asperity contact, blow-by/blow-back flow and cavitation have been coupled with the lubrication model.

The established model has been compared with the traditional model that deals with cavitation by using the Reynolds boundary condition algorithm. The cavitation zone, pressure distribution and density distribution between the piston ring and the cylinder have also been predicted. Studies of the changing trend for the pressure distribution and the cavitation zone at few typical crank angles have been listed to illustrate the cavitation changing rule. The analysis of the results indicates that the developed simulation model can adequately illustrate the lubrication problem of the piston ring system. All the analyses will provide guidance for the oil film rupture and the reformation process.

A two-dimensional cavitation model based on the mass-conserving theory has been built. The cavitation-forming and -developing process for the piston ring–liner lubrication has been studied. Non-cavitation occurs in the vicinity of top dead center and bottom dead center. The non-cavitation period will be longer in the vicinity of 360° of crank angle. The density distribution in the cavitation zone can be obtained.

This final chapter pulls together some of the observations and findings from the others in the book, and presents a final argument for undoing the ‘affectless consensus’ of research. It synthesizes a number of ‘affective scenes’ that are present across the various chapters, and uses these to build an argument for why affect should not be understand as simply synonymous with emotion. It concludes with a proposal for an ‘affective project’ to build off the findings that are found in the book.
