Effective Interventions When Working With Cambodian Refugees: A Systematic Literature Review

In this systematic review, an investigation of research on effective interventions when working with Cambodian refugees was conducted. Through a comprehensive literature search, 5 articles met the set inclusion criteria. Peer-reviewed journal articles on quantitative or qualitative research studies on Cambodian refugees as the data resource. The review found four categories and strategies of interventions: traditional healers, pharmacotherapy treatment, implication of treatment, and assessment issues, family intervention, and use of interpreters. The results of the review demonstrated an overall improvement of traumatized Cambodian refugees. The majority of the interventions demonstrated pharmacotherapy for symptomology of diagnosis. Furthermore, this project indicates the ongoing need for cultural sensitivity, curiosity, and responsiveness as means for effective cross-cultural interventions

Early Discharge Planning to Improve Throughput

Early discharge planning can improve the safety and outcomes of hospitalized patients. The aim of the multidisciplinary team early discharge rounds was to manage patient flow by removing discharge barriers to reduce the length of stay in the medical/surgical unit. The overall goal of the process improvement project was to make inpatient beds available to admit patients from the emergency department, reducing long ED boarding, and decrease the hours of diversion. The PICOT question for this project was: in the Veteran population (P) in the VA medical/surgical unit, early discharge planning with an interdisciplinary team (I) compared to regular discharge rounds alone (C) will improve patient flow and will result in decreased emergency room medical diversion or prolonged ED boarding (O) within 10 weeks (T). The early discharge planning had a significant impact on the medical/surgical unit in helping to decrease the ED medical diversion. Although the mean length of stay from 2022 to 2023 was not significantly changed, the early discharge intervention for the 10-week period on the medical/surgical unit concurred simultaneously with a decreased in diversion hours in the emergency department by 72 hours from the 2022 to 2023 time frames

Towards the understanding of variable amplitude fatigue

Fatigue life estimation is of high importance during the design stage of a machine or component. Basic fatigue calculations are made based on the use of an S-N curve. As far as constant amplitude loads are applied, this approach works well. However, most part of components in service are subjected to a variable amplitude load spectrum. In this case, linear approaches for fatigue life estimation can lead to over conservative results, which in other words means a heavier and more expensive machine. To further investigate the effect of (complex) service spectra (measured or statistically calculated), simpler load variations must be studied. This paper aims to show the general trend of these events and suggest the underlying physical phenomena behind load and interaction effects. As it will be highlighted, overloads are frequent in a spectrum and they are believed to be responsible for retardation effects. The plasticity induced crack closure mechanism is the most profound explanation for them to occur

Fatigue fracture assessment of high strength steel using thermographic analysis

Fatigue behaviour is most commonly evaluated in uni-axial cyclic stress tests using standardised dog-bone samples. When components are sharply bent into shape and subjected to cyclic loading, the fatigue damage will accumulate at the inside of the bend. This paper reports on an experimental investigation about the feasibility of infrared thermographic techniques to monitor fatigue damage initiation and accumulation. By monitoring spectral components of the thermal response, the fatigue limit, the onset of crack initiation and the ratio of initiation to propagation lifetime can all be determined. Also the effect of surface treatments on initiation properties is investigated. Most results are consistent with expected behaviour based on a previous study, indicating that thermographic techniques have a greater sensitivity and can be used to reduce the number of samples and time required for fatigue characterisation

A review of non-destructive testing techniques for the in-situ investigation of fretting fatigue cracks

© 2020 The Authors Fretting fatigue can significantly reduce the life of components, leading to unexpected in-service failures. This phenomenon has been studied for over a century, with significant progress being made during the past decade. There are various methods that have been used to study fretting fatigue cracks in order to gain a greater understanding of the effects of fretting fatigue. Destructive methods are traditionally used to observe fretting fatigue cracks. Although useful in determining crack location, crack length, crack propagation modes, crack path and shape, it is not efficient or reliable for time based measurements. Non-destructive testing has developed in recent years and now in-situ monitoring can be used during testing in order to increase the understanding of fretting fatigue. This paper presents a review of non-destructive testing techniques used in-situ during fretting fatigue testing, which are compared in order to conclude the suitability of each technique. Recent developments in non-destructive techniques that could be also applied for fretting fatigue tests are also discussed, as well as recommendations for future research made

Rapid determination of fretting fatigue limit by infrared thermography

This paper demonstrates the feasibility of infrared thermography to determine the so-called fretting fatigue limit. Fretting fatigue tests are performed on aluminum and steel specimens. The coupled fatigue and tangential loads are sequentially increased (block loading) whilst the normal load is kept constant for all blocks. The temperature data is processed and analyzed using a Fast Fourier Transform (FFT) algorithm implemented in the commercial software Matlab. It is demonstrated that the second harmonic of the temperature signal can be linked to the specific loading block below which no or negligible damage is generated in the specimen. The stress amplitude of this block is considered to be a best estimate of the fretting fatigue limit. A constant amplitude fretting fatigue test with this stress amplitude confirmed that the specimen remains intact at 107 cycles
