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

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

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

Interprofessional Learning during an International Fieldwork Placement

The need for competent interprofessional health care professionals is well recognised. Various educational activities have been developed to facilitate the development of interprofessional competence. In this paper we describe an interprofessional, fieldwork experience conducted in a developing country, and the learning gained by the first cohort of students who completed the five week immersion. Eight final year students from Medicine, Occupational Therapy, Physiotherapy and Speech Pathology were interviewed pre- and post-placement by an independent researcher. The transcribed interviews were analysed thematically. Findings indicated that over the placement students gained an appreciation of the skills of the other disciplines and were able to move beyond a textbook definition of what a certain profession did to acquire a real understanding of interprofessional practice. However, students reported that this understanding was predicated on their first clarifying the extent to which they were working in a transdisciplinary or interdisciplinary team, and becoming more confident in their own disciplinary contribution without reliance on formal documentation or standardised assessments. Using daily team discussions, self-reflections and discussions with clinical educators, the students learned to prioritise their busy caseload, share resources and skills, and facilitate team members to achieve therapeutic goals. The interprofessional learning took place in an intercultural context where the students learned to work with children with severe disabilities, with staff with different classroom approaches, and with interpreters, while adjusting emotionally to the level of unmet need of many of the children. Based on the students' experiences, immersion in an intercultural fieldwork experience is a useful way to facilitate interprofessional learning

Structural role of the tyrosine residues of cytochrome c

The tertiary structures of horse, tuna, Neurospora crassa, horse [Hse65,Leu67]- and horse [Hse65,Leu74]-cytochromes c were studied with high-resolution 1H n.m.r. spectroscopy. The amino acid sequences of these proteins differ at position 46, which is occupied by phenylalanine in the horse proteins but by tyrosine in the remaining two, and at positions 67, 74 and 97, which are all occupied by tyrosine residues in horse and tuna cytochrome c but in the other proteins are substituted by phenylalanine or leucine, though there is only one such substitution per protein. The various aromatic-amino-acid substitutions do not seriously affect the protein structure
