So, if food can be seen as the fuel that maintains the fire within us - and the fuel serves only to prepare that ailment or to raise the body heat as external additive - shelter and clothes serve only for keeping the generated or absorbed body heat." Walden or life in the woods - Henry D. Thoreau. So, without a doubt, energy is a key issue in our lives. Source

This paper presents details of the installation and performance of carbonated soil-MgO columns using a laboratory-scale model auger setup. MgO grout was mixed with the soil using the auger and the columns were then carbonated with gaseous CO2 introduced in two different ways: one using auger mixing and the other through a perforated plastic tube system inserted into the treated column. The performance of the columns in terms of unconfined compressive strength (UCS), stiffness, strain at failure and microstructure (using X-ray diffraction and scanning electron microscopy) showed that the soil-MgO columns were carbonated very quickly (in under 1 h) and yielded relatively high strength values, of 2.4-9.4 MPa, which on average were five times that of corresponding 28-day ambient cured uncarbonated columns. This confirmed, together with observations of dense microstructure and hydrated magnesium carbonates, that a good degree of carbonation had taken place. The results also showed that the carbonation method and period have a significant effect on the resulting performance, with the carbonation through the perforated pipe producing the best results.

Rotationally molded polyethylene water storage tanks have been produced since the 1950s when the technology became available for this manufacturing process. For circular tanks manufactured in this way, the traditional method of design has been based on hand calculations considering internal hydrostatic pressure from the stored liquid as the primary applied load. This study presents the results of the optimal structural design of 16 circular polyethylene water tanks of various sizes. Based on the results derived, optimal design recommendations for these tank structures are provided when both hydrostatic pressure and wind loads are applied. © 2011 American Society of Civil Engineers.

Objective To engage a group of people with relevant lived experience in the development of a text-messaging intervention to reduce repetition of self-harm. Background Contact-based interventions, such as follow-up letters, postcards and telephone calls, have shown potential to reduce repetition of self-harm in those who present at Accident and Emergency departments. Text messaging offers a low-cost alternative that has not been tested. We set out to develop a text-based intervention. The process of intervention development is rarely reported and little is known about the impact of service user involvement on intervention design. Method We held a series of six participatory workshops and invited service users and clinicians to help us work out how to get the right message to the right person at the right time, and to simulate and test prototypes of an intervention. Results Service users rejected both the idea of a generic, 'one size fits all' approach and that of 'audience segmentation', maintaining that text messages could be safe and effective only if individualized. This led us to abandon our original thinking and develop a way of supporting individuals to author their own self-efficacy messages and store them in a personal message bank for withdrawal at times of crisis. Conclusions This paper highlights both the challenge and the impact of involving consumers at the development stage. Working with those with lived experience requires openness, flexibility and a readiness to abandon or radically revise initial plans, and may have unexpected consequences for intervention design. © 2010 Blackwell Publishing Ltd.

Background To establish demographics, referral patterns and clinical characteristics of patients attending an emergency eye service within a major public tertiary teaching hospital and to identify possible targets to improve delivery of patient care. Methods Retrospective study of all patients (N=504) attending an acute eye clinic over a representative 2-week period within Greenlane Clinical Centre, Auckland. Results Mean age was 42.4±20.6 years with mean visual acuity of 6/10. Referrals came from: general-practitioners (GP) (26.2%), self-referrals (18.6%), hospital medical-officers (7.4%), accident and emergency clinics (6.6%) and optometrists (2.2%). 39.1% of patients were follow-up reviews. Main presenting symptoms were pain, red eye and reduced vision. Average waiting-time was 119±98 min. Major diagnoses were trauma, uveitis and adenoviral keratoconjunctivitis (AKC). Males were more likely to present with ocular trauma, whereas females were more likely to exhibit uveitis, contact-lens related keratitis and AKC. Outcomes included follow-up (48.2%), referral to speciality ophthalmology care (19.0%), referral to other clinics (5.75%), and discharge (33.7%). Conclusion A significant proportion of presentations could have been appropriately referred to outpatient departments or potentially managed by primary healthcare providers. Potential initiatives to manage excessive workload demands might target prevention of ocular trauma, improved contact-lens education, limiting the spread of AKC and improved GP education. © NZMA.
