EVERYONE today is busily engaged in devising new methods, bringing about economies in motions, and applying incentives, but is enough attention being paid to the maintenance mechanics, from the human aspect, in these applications of work study?

Passivity and localized corrosion is discussed using iron, iron‐chromium, iron‐chromium‐nickel alloys and aluminium as examples. A brief description is given of the prevailing ideas regarding the nature of the passive film and the processes by which its protective properties are lost when breakdown of passivity and localized corrosion occurs.

The purpose of this paper is to assess multidimensional body image concerns in a sample of obese women seeking bariatric surgery at an outpatient hospital clinic in Hamilton, Ontario, Canada.

A sample of obese adult women seeking bariatric surgery at an outpatient medical clinic in Hamilton, Ontario, Canada (n=148) completed various self-report measures of body image concerns, including body image dysphoria, body image quality of life, body image investment, and appearance satisfaction. Participant scores were compared to normative data. Correlations between body image concern measures and body mass index (BMI) were examined.

Participants endorsed more body image dysphoria, more negative body image quality of life, and less appearance satisfaction than normative samples. BMI was not correlated with body image concern scores.

Interventions aimed at reducing body image disturbance in obese women should target multiple components of body image concern. Decisions about who should receive interventions should not be based on BMI status.

The majority of research on body image concerns focuses exclusively on evaluative constructs such as body image dissatisfaction. The current study examined affective, cognitive, and behavioural body image constructs. A better understanding of the multidimensional nature of body image concerns in obese women seeking bariatric surgery informs the development of effective, targeted interventions.

NEXT TO banking, we are informed, Business Consultancy is the most favoured profession for graduates in the United States and it is likely, as in so much else, that here in Britain the same trend will be followed. It follows, as the famous query in a one‐time quiz member put it, that ‘it all depends on what you mean by Business Consultancy’.

Electrochemical techniques are described of direct use to chemical processors for optimum material selection in designing and maintaining new plants as well as corrosion monitoring and control in operating existing plants. Reference is made to the three corrosion forms most responsible for failures in chemical equipment, i.e.: general corrosion, localised corrosion, and stress‐corrosion cracking. Practical examples are given of successful industrial application of electrochemical methods: 1) for controlling active corrosion of a stainless alloy in pressure reactors operated with hot sulphuric acid solution and 2) for preventing stress corrosion cracking of a low‐alloy steel in a pressure absorption tower operated with hot alkali carbonate solution.

The purpose of this paper is to revisit a decade after its conception the Representational State Transfer (REST) architectural style and analyzes its relevance to address current challenges from the Library and Information Science (LIS) discipline.

Conceptual aspects of REST are reviewed and a generic architecture to support REST is presented. The relevance of the architecture is demonstrated with the help of a case study based on the collection registration database of the Cooper-Hewitt National Design Museum.

The authors argue that the “resources and representations” model of REST is a sustainable way for the management of web resources in a context of constant technological evolutions.

When making information resources available on the web, a resource-oriented publishing model can avoid the costs associated with the creation of multiple interfaces.

This paper re-examines the conceptual merits of REST and translates the architecture into actionable recommendations for institutions that publish resources.

The purpose of this paper is to investigate the thermomechanical response of four well-known lead-free die attach materials: sintered silver, sintered nano-copper particles, gold-tin solders and silver-tin transient liquid phase (TLP) bonds.

This examination is conducted through finite element analysis. The mechanical properties of all die attach systems, including elastic and Anand creep parameters, are obtained from relevant literature and incorporated into the numerical analysis. Consequently, the bond stress-strain relationships, stored inelastic strain energies and equivalent plastic strains are thoroughly examined.

The results indicate that silver-tin TLP bonds are prone to exhibiting higher inelastic strain energy densities, while sintered silver and copper interconnects tend to possess higher levels of plastic strains and deformations. This suggests a higher susceptibility to damage in these metallic die attachments. On the other hand, the more expensive gold-based solders exhibit lower inelastic strain energy densities and plastic strains, implying an improved fatigue performance compared to other bonding configurations.

The utilization of different metallic material systems as die attachments in power electronics necessitates a comprehensive understanding of their thermomechanical behavior. Therefore, the results of the present paper can be useful in the die attach material selection in power electronics.

Childhood traumatic brain injury (CTBI) is one of the most common causes of mortality and disability in children and adolescents that impacts on neuropsychological, social and psychological development. A disruption of development in these areas often results in long-term problems with interpersonal relationships, participation in leisure and social activities and employment status. These social and psychological problems appear to persist longer in comparison to other functional consequences, although evidence is scarce. The purpose of this paper is to investigate social and psychological outcomes 15 years post-injury.

In all, 36 participants post-CTBI (mean age 21.47 years, SD=2.74), 16 males) and 18 healthy controls (mean age 20.94 years, SD=2.21), 12 males) were recruited from a larger sample of a longitudinal study conducted at the Royal Children's Hospital, Melbourne, Australia. Information about social and psychological functioning was collected via questionnaires completed at 15 years post-injury.

Results showed that post-CTBI, adolescents and young adults reported elevated risk of developing psychological problems following their transition into adulthood. CTBI survivors reported greatest problems on internalizing symptoms such as depression, anxiety and withdrawal.

Despite the reported psychological symptoms, the survivors of CTBI did not report more social problems than their peers. Further research is needed to identify long-term social and psychological problems so that optimal intervention may be provided.

This is the first perspective longitudinal study investigating the young adults perspective of their long-term psychosocial outcomes following CTBI.

Sovereignty retains considerable currency today insofar as it fuses ordinary understandings of the state, the nation, and democracy. Against widespread expectations, however, the European Union has increasingly harnessed sovereignty as a source of vitality. We are thus witnessing a mainstreaming of populist politics, as the rhetoric of sovereignty no longer disqualifies new EU institutions and policies. This can be better understood if we consider sovereignty, from a constructivist perspective, as an evolving set of practices. First, sovereignty evolves within political and administrative circles, as European officials act to modify longstanding practices of state sovereignty. Second, sovereignty evolves in an increasingly politicized context, as political leaders dramatize EU crises in order to mobilize coalitions around new practices of popular sovereignty. This dual dynamic of state sovereignty and popular sovereignty is demonstrated in the case of the Eurozone and then extrapolated to the current trajectory of the EU polity against the benchmark of US federalism after the Civil War. An open question is whether sovereignty practices in the European Union will continue to evolve without compromising the Union's cosmopolitan and liberal objectives.

In power electronics, there are various metallic material systems used as die attachments. The complete understanding of the thermomechanical behavior of such interconnections is very important. Therefore, this paper aims to examine the thermomechanical response of four famous die attach materials, including sintered silver, sintered nano-copper particles, gold-tin solders and silver-tin transient liquid phase (TLP) bonds, using nonlinear finite element analysis.

During the study, the mechanical properties of all die attach systems, including elastic and viscoplasticity parameters, are obtained from literature studies and hence incorporated into the numerical analysis. Subsequently, the bond stress–strain relationships, stored inelastic strain energies and equivalent plastic strains are thoroughly examined.

The results showed that the silver-tin TLP bonds are more likely to develop higher inelastic strain energy densities, while the sintered silver and copper interconnects would possess higher plastic strains and deformations. Suggesting higher damage to such metallic die attachments. The expensive gold-based solders have developed least inelastic strain energy densities and least plastic strains as well. Thus, they are expected to have improved fatigue performance compared to other bonding configurations.

This paper extensively investigates and compares the mechanical and thermal response of various metallic die attachments. In fact, there are no available research studies that discuss the behavior of such important die attachments of power electronics when exposed to mechanical and thermomechanical loads.
