The Effects of pH and Soaking Time on the Repulping of Old Corrugated Containers (OCC)

Efforts to increase production capacity and meet recycled fiber content regulations include the utilization of recycled OCC as a fiber source. This fiber source is predominantly softwoods which are characteristically longer and stronger than hardwood fibers. However, the corrugating medium found in OCC contains mostly hardwood fibers which are shorter and more brittle than the desired softwoods. In addition, the medium contains a significant amount of lignin that interferes with fiber bonding. Therefore, the resulting paper web\u27s strength is decreased. The paper industry is forced to find ways to achieve maximum strength from an inferior starting material. One method under investigation is caustic soaking. This study investigates the effects of pH and soaking time on the recycling of OCC and attempts to identifying the optimum repulping conditions. The OCC furnish was repulped at several pH levels. At each pH level, the stock was than soaked for various lengths of time. Subsequent testing of the pulps and handsheets, and analyses of the results were completed in order to determine the above mentioned objectives. The effects of pH and soaking time on the OCC pulp and resulting handsheets are discussed in this report. The optimum repulping conditions were determined to be at a pH of 9 and a soaking time of 5 to 10 hours. Statistically significant strength increases in the handsheets produced at these optimum conditions were found to range between 5 and 19 percent for the various tests performed

Building service capacity within a Regional District Mental Health Service: recommendations from an indigenous mental health symposium

[Abstract]: In response to recent developments within the mental health services of south-east Queensland, the Toowoomba District Mental Health Service (TDMHS) has developed a Model of Service Delivery, which outlines the range of services provided for consumers across their lifespan. Indigenous consumers of the TDMHS come from a wide area of communities in the surrounding shires (Rural, remote and metropolitan areas (RRMA) 4-7). It was recognised by the service that Indigenous mental health consumers have unique needs and, because of these needs, this area of service delivery required greater attention and further development. In December 2004, a symposium was organised by the service to bring together a range of speakers and delegates working in the area of Indigenous mental health to discuss issues and work towards developing strategies to enable the service to better meet the needs of Indigenous consumers in this region of south-east Queensland. Issues: The symposium program consisted of keynote speakers and invited papers and culminated with an afternoon workshop that collated the symposium’s main issues and themes around building service capacity for Indigenous mental health consumers. The objective of the workshop was ‘Identifying ways to meet Indigenous mental health needs’. This workshop gave the delegates a chance to reflect, discuss and brainstorm the major issues of concern relating to this question. A group facilitator guided the discussion and organised the delegates into groups to evaluate, debate and propose recommendations for each of the major issues that emerged. Lessons learned: The feedback and discussion arising from the workshop is presented. Sixteen major themes emerged from the workshop. Seven of these were voted by the participants as being dominant and in greatest need of discussion: (1) communication; (2) cultural respect; (3) culturally appropriate clinical tools; (4) supportive management; (5) patient compliance; (6) career structure; and (7) empowerment. These seven themes are discussed and recommendations arising from the workshop are noted

Barriers to the up-take of telemedicine in Australia - A view from providers

Introduction: The continued poorer health status of rural and remote Australians when compared with their urban counterparts is cause for concern. The use of advanced technology to improve access to health care has the potential to assist in addressing this problem. Telemedicine is one example of such technology which has advanced rapidly in its capacity to increase access to healthcare services or provide previously unavailable services. The important anticipated benefits of greater access to healthcare services are improved health outcomes and more cost-effective delivery

BCG Vaccination in HIV-Infected Children

Despite the use of Bacillus Calmette-Guérin (BCG) vaccination for many years, infants and young children exposed to adults with infectious forms of tuberculosis (TB) are at high risk of developing complicated TB disease. This risk is much higher among HIV-infected children, and data on BCG protective efficacy in HIV-infected children is lacking. Recent research on BCG safety in HIV-infected infants has resulted in policy shifts, but implementation is challenging. New approaches to preventing TB among infants and children, particularly HIV-infected infants, are needed. This paper briefly reviews BCG safety and efficacy considerations in HIV-infected infants and discusses other approaches to preventing TB, including new TB vaccines and vaccination strategies

Short-term treatment outcomes of children starting antiretroviral therapy in the intensive care unit, general medical wards and outpatient HIV clinics at Red Cross War Memorial Children’s Hospital, Cape Town, South Africa: A retrospective cohort study

Background: Many HIV-infected children are initiated on antiretroviral therapy (ART) during hospitalisation in South Africa (SA). No published data on these outcomes exist.Objectives: To assess the short-term outcomes of children initiated on ART in the intensive care unit (ICU), general medical wards (GMWs) and outpatient HIV clinics (OHCs) at Red Cross War Memorial Children’s Hospital (RCWMCH), Cape Town, SA.Methods: We conducted a retrospective cohort study of HIV-infected children aged <13 years commenced on first-line ART between January 2008 and December 2011. Outcomes included death, virological suppression and changes in CD4 count. Kaplan-Meier estimates, multivariate Cox proportional hazard ratios and logistic regression were used to estimate outcomes at 6 months.Results: One hundred and six children were commenced on ART in the ICU, 509 in the GMWs and 127 in the OHCs; 65.7% of all children were <12 months old. Of children qualifying for rapid ART initiation according to the 2013 national treatment guidelines, 182 (24.9%) started therapy within 7 days of diagnosis. Overall mortality was 6.4% (95% confidence interval (CI) 4.9 - 8.4). Of children remaining in care at RCWMCH, 51.0% achieved a CD4 percentage ≥25% and 62.3% a viral load ≤50 copies/mL 6 months after ART initiation. Mortality was higher in the ICU cohort (13.2%) than in the GMW and OHC cohorts (5.5% and 3.9%, respectively, log-rank p=0.004). Predictors of mortality included moderate underweight (adjusted hazard ratio (aHR) 2.4; 95% CI 1.1 - 5.2), severe underweight (aHR 3.2; 95% CI 1.6 - 6.5), absence of caregiver counselling sessions (aHR 2.9; 95% CI 1.4 - 6.0) and ART initiation in the ICU (aHR 2.6; 95% CI 1.4 - 4.9).Conclusion: These results highlight the importance of understanding the context in which children are initiated on ART, when comparing outcomes in different settings

A decade of Australian Rural Clinical School graduates: Where are they and why?

Introduction: The Australian Rural Clinical School (RCS) initiative has been addressing the rural medical workforce shortage at the medical education level for over a decade. A major expectation of this initiative is that it will improve rural medical workforce recruitment and subsequent retention through a rurally based undergraduate clinical training experience. The longitudinal nature of these workforce initiatives means that definitive evidence of its impact on the shortage of rural doctors is yet to be provided; however, to date cross-sectional studies are accumulating a measure of efficacy for these initiatives by monitoring early career factors such as internship location choice and speciality choice of RCS graduates. This article reports on a study in one RCS that is monitoring the impact of rural undergraduate clinical training on trends in workforce participation patterns of its graduates as long as 9 years in the workforce. Career location and speciality choice are reported as well as perspectives on early career intentions and the reality of making career and life decisions as a doctor in the medical workforce

Exploring resilience in rural GP registrars – implications for training

Background: Resilience can be defined as the ability to rebound from adversity and overcome difficult circumstances. General Practice (GP) registrars face many challenges in transitioning into general practice, and additional stressors and pressures apply for those choosing a career in rural practice. At this time of international rural generalist medical workforce shortages, it is important to focus on the needs of rural GP registrars and how to support them to become resilient health care providers. This study sought to explore GP registrars' perceptions of their resilience and strategies they used to maintain resilience in rural general practice
