Effect of contact pressure on fretting fatigue behavior of Ti-1023

With a new test facility, we have investigated fretting fatigue properties of Ti-1023 titanium alloy at different contact pressure. Both fatigue fracture and fretting scar were analyzed by scanning electron microscopy (SEM). Moreover, the depth of crack initiation area in fatigue fracture has been analyzed quantitatively, to investigate the relationship between the depth of crack initiation area and the fretting fatigue strength. The changing trends of the depth of crack initiation area and fretting fatigue strength with the increase of contact pressure show obvious opposite correlations. The depth of crack initiation area increases rapidly with the increase of contact pressure at low contact pressure (smaller than 10 MPa), and the fretting fatigue strength drops rapidly. At the contact pressure of 10–45 MPa, both the depth of crack initiation area and the fretting fatigue strength do not vary significantly. Contact pressure influences fatigue strength through influencing the initiation of fatigue crack. The main damage patterns are fatigue flake and plow.

Low cycle fatigue properties of CLAM steel at room temperature

The low cycle fatigue (LCF) properties and the fracture behavior of China Low Activation Martensitic (CLAM) steel have been studied over a range of total strain amplitudes from 0.2 to 2.0%. The specimens were cycled using tension-compression loading under total strain amplitude control. The CLAM steel displayed initial hardening followed by continuous softening to failure at room temperature in air. The relationship between strain and fatigue life was predicted using the parameters obtained from fatigue test. The factors effecting on low cycle fatigue of CLAM steel consisted of initial state of matrix dislocation arrangement, magnitude of cyclic stress, magnitude of total strain amplitude and microstructure. The potential mechanisms controlling the stress response, cyclic strain resistance and low cycle fatigue life have been evaluated.

Microstructure and high cycle fatigue fracture surface of a Ti-5Al-5Mo-5V-1Cr-1Fe titanium alloy

Because of the requirements for the damage tolerance and fatigue life of commercial aircraft components, the high cycle fatigue (HCF) properties of Ti–5Al–5Mo–5V–1Cr–1Fe titanium alloy forgings are important. The effects of microstructure types of the α+β titanium alloy on fatigue properties need to be understood. In this paper, by analysing the fracture surfaces of the titanium alloy having four types of microstructure, the effects of microstructure are investigated. The differences of initiation areas and crack propagation among different microstructures were studied. It was found that the area of the initiation region decreases in the order of coarse basketweave, fine basketweave, Widmanstätten, and bimodal microstructure.

Differences Between Irish and Australian Psychiatric Nurses' Family Focused Practice in Adult Mental Health Services

Psychiatric nurses’ practice with parents who have mental illness, their children and families is an important issue internationally. This study provides a comparison of Irish and Australian psychiatric nurses’ family focused practices in adult mental health services. Three hundred and forty three nurses across Ireland and 155 from Australia completed the Family Focused Mental Health Practice Questionnaire. Cross-country comparisons revealed significant differences, in terms of family focused skill, knowledge, confidence and practice. Australian psychiatric nurses engaged in higher family focused practice compared to Irish nurses. The comparative differences between countries may be attributable to differences in training, workplace support and policy.

Mental illness or mental distress; stigma and concealment in University students - a discussion paper

This discussion paper addresses the issue of mental distress, sometimes mis- perceived or misinterpreted as mental illness. The
focus is on positive psychology. Reflecting in part on a UK-based study with younger University students studying to health
related degrees, nursing, midwifery and medicine (N = 12), many of the students were apparently suffering dis-stress with
disordered eating at least in part being used as a coping mechanism. However notwithstanding that they were at the end of
their first year studies in health, a significant number of the students interpreted their approach to eating as a mental illness.
Consequently, many within the study felt stigmatised and were reluctant to acknowledge certainly to the University health care
authorities that there was an issue; perceiving both academic and career/professional consequences of mental health labelling. The
paper approaches the issue of mental health from a health promoting perspective, reflecting against the theory of salutogenesis
and its focus within the three dimensions of comprehensibility, manageability and meaningfulness as an approach to building
resilience and managing stressors to better facilitate a sense of coherence. Complex manifestations of distress and poor coping
mechanisms can in some cases be misinterpreted or miss perceived as mental illness. Promoting mental health and reducing the
stigma of mental illness or the misperception of mental distress as mental illness, would need to be addressed in order to more
effectively outreach certainly to younger University students who might be at risk. The focus should be on how better to promote
their sense of coherence.

Cancer and serious mental illness – patient, caregiver and professional perspectives: study protocol

Aim: To explore the experience of serious mental illness and cancer from the perspective of patients, significant others and healthcare professionals involved in their care. Background: Serious mental illness is associated with poorer cancer outcomes. Those suffering from this comorbidity receive fewer specialist interventions and die earlier than the general population. Prior qualitative research in this area has comprised of a single study focussing on healthcare professionals and there is little evidence regarding the experiences of patients and caregivers.Design: A qualitative exploration using approximately 36 semi-structured interviews.Methods: Semi-structured digitally recorded interviews conducted with: adults living with serious mental illness and diagnosed with cancer; those providing them with informal support and care; and healthcare professionals. Questions will focus on the experience of having cancer and serious mental illness or caring for someone with this comorbidity, experiences of healthcare and priorities for patients and carers. Framework analysis will be used. Research Ethics Committee and Trust Research & Development approval was obtained. A steering group comprising six people with experience of either cancer or mental illness provided feedback and ratified the patient information sheets and interview schedules. Discussion: There is a paucity of research addressing stakeholder perspectives on the experience of cancer and of cancer services for people with serious mental illness. Dissemination of findings will inform practice relating to the care of an often neglected population, informing better support for their significant others and the professionals involved in their care.

Learning, fatigue and preference formation in discrete choice experiments

While the repeated nature of Discrete Choice Experiments is advantageous from a sampling efficiency perspective, patterns of choice may differ across the tasks, due, in part, to learning and fatigue. Using probabilistic decision process models, we find in a field study that learning and fatigue behavior may only be exhibited by a small subset of respondents. Most respondents in our sample show preference and variance stability consistent with rational pre-existent and
well formed preferences. Nearly all of the remainder exhibit both learning and fatigue effects. An important aspect of our approach is that it enables learning and fatigue effects to be explored, even though they were not envisaged during survey design or data collection.
