Appraising community driven health research with Aboriginal and Torres Strait Islander communities: a scoping review using the Aboriginal and Torres Strait Islander Quality Appraisal Tool

Most research involving Aboriginal and Torres Strait Islander peoples has been conducted by non-Indigenous people and has not been a positive experience for many Aboriginal and Torres Strait Islander communities. This scoping review maps approaches to health research involving Aboriginal and Torres Strait Islander peoples and communities in Australia from the last two decades. A literature search found 198 papers, of which 34 studies met the inclusion criteria. The Aboriginal and Torres Strait Islander Quality Appraisal Tool was then used to map the quality of the reported community driven research. The Quality Appraisal Tool privileges, Aboriginal and Torres Strait Islander people's epistemologies and ethical research governance. The findings reported on strengths and identified areas for improvement in reporting community driven research

High impact pressure regulator withstands impacts of over 15,000 g

High impact pressure regulator used with a high impact gas scannograph withstands impacts of over 15,000 g. By the passage of fluid through the first and second chambers of the regulator, the pressure of the scannograph is regulated from a specific input valve to the desired output pressure valve

Form, function and physics: The ecology of biogenic stabilization

The effect of biological cohesion on the behaviour of sediments is gaining increasing notice. This is partly supported by ecological theory in terms of the role of organisms as “ecosystem engineers” and the associated discussion of “niche construction”, suggesting an evolutionary role for habitat modification by biological action. In addition there is a strong societal and policy drive toward the “ecosystem approach” supporting an integrated examination of the functional roles of biota in selected habitats. In this context the increasing recognition of the importance of biological activity in the mediation the erosion, transport, deposition and consolidation (ETDC) cycle of sediments is important and advances in technology will improve our ability to examine these effect under their natural settings. This will shortly be combined with vastly enhanced molecular tools that will allowthe discrimination of microbial biodiversity and examination of their metabolism contribution to ecosystem function. This may lead to a step-change in our ability to research the influence of microbiota on natural sediment dynamics and opens an exciting era for new interdisciplinary research

Effectiveness of Shot Peening In Suppressing Fatigue Cracking At Non-Metallic Inclusions In Udimet(Registered Trademark)720

The fatigue lives of modern powder metallurgy disk alloys can be reduced over an order of magnitude by cracking at inherent non-metallic inclusions. The objective of this work was to study the effectiveness of shot peening in suppressing LCF crack initiation and growth at surface nonmetallic inclusions. Inclusions were carefully introduced at elevated levels during powder metallurgy processing of the nickel-base disk superalloy Udimet 720. Multiple strain-controlled fatigue tests were then performed on machined specimens with and without shot peened test sections at 427 C and 650 C. The low cycle fatigue lives and failure initiation sites varied as functions of inclusion content, shot peening, and fatigue conditions. A large majority of the failures in as-machined specimens with the introduced inclusions occurred at cracks initiating from inclusions intersecting the specimen surface. These inclusions reduced fatigue life by up to 100X, when compared to lives of material without inclusions residing at specimen surface. Large inclusions produced the greatest reductions in life for tests at low strain ranges and high strain ratios. Shot peening improved life in many cases by reducing the most severe effects of inclusions

Suggested Insecticides for Managing Cotton Insects in the Southern, Eastern and Blackland Areas of Texas--2008

15 pp., 5 tablesThis publication lists suggested insecticides (by brand name) and application rates for controlling cotton pests found in the Southern, Eastern and Blackland areas of Texas. This publication should be used in conjunction with publication E-5 (nonchemical pest management practices) to avoid insecticide misuse

Managing Cotton Insects in the Southern, Eastern and Blackland Areas of Texas 2008

17 pp., 15 tables, 2 charts, 10 drawingsCotton insect management techniques, including cultural control techniques that reduce the risk of crop damage, are discussed. The emphasis is on monitoring and identifying insect populations in cotton. A supplement (E-5A) lists insecticides recommended for cotton insect control

Probation staff experiences of managing suicidal and self-harming service users

The current study sought to explore the impact of suicidal behaviours on probation staff, in relation to their experiences of working with Probation service users who have carried out suicide, attempted suicide or self-harm. Thirteen in-depth interviews were carried out with probation staff who had direct contact with Probation service users in one Probation area, and had varying degrees of experience of managing suicidal or self-injurious service users. These were analysed using Thematic Analysis and five themes were identified. Findings indicate that staff felt that suicide and self-harm by service users are serious issues which need to be recognised and dealt with in an effective yet compassionate manner. However not attending the Suicide Prevention Training or lack of experience was perceived as restricting their ability to know how to deal with these individuals, and offer support. Furthermore, staff were emotionally affected by these incidents and it is recommend that they should continue to be provided with access to appropriate support services after an incident
