    Abstract The widespread adoption and sustained use of modern cookstoves has the potential to reduce harmful effects to climate, health, and the well-being of approximately one-third of the world’s population that currently rely on biomass fuel for cooking and heating. In an effort to understand and develop cleaner burning and more efficient cookstoves, 15 stove design and fuel/loading combinations were evaluated in the laboratory using the International Workshop Agreement’s five-tiered (0–4) rating system for fuel use and emissions. The designs evaluated include rocket-type combustion chamber models including reduced firepower, sunken pots, and chimneys (three stoves); gasifier-type combustion chambers using prepared fuels in the form of wood pellets (four stoves); forced draft stoves with a small electric fan (five stoves); and a single insulated charcoal stove with preheated secondary air. It was found that a charcoal burning stove was the only stove to meet all the Tier 4 levels of performance. Achieving over 40% thermal efficiency at high power was made possible by reducing firepower and gaps around the pot, although batch-fed stoves generally do not “turn down” for optimal low power performance. While all stoves met Tier 4 for carbon monoxide, only stoves equipped with electrical fans reduced respirable particulate matter to Tier 4 levels. Finally, stoves with chimneys and integrated pots were fuel efficient and virtually eliminated indoor emissions. It is hoped that these design techniques will be useful in further development and evolution of high-performance cookstove designs.

    Abstract The acceleration of sanitation delivery towards meeting the South African Government's target of completely eradicating the existing backlogs by 2010, has led to a surge of activities. As part of its strategy for ensuring that basic sanitation is provided, the policy has recommended that a ventilated improved pit latrine (VIP) is considered as the basic minimum requirement in the form of a sanitation technology. The up-scaling and delivering of sanitation in many cases in the form of VIPs and its derivatives, as well as urine diversion technology are beginning to pose many technical challenges. The principles on which they have been designed are not always being observed in practice. As a result, some systems are filling up much faster than expected. Research has found that the breakdown in the faeces is not happening as would be expected in an anaerobic reactor, and that the drying of faeces in humid conditions, even with the use of drying agents, is not optimum. These problems, which are being experienced in the field, will have long term repercussions on the sustainability of sanitation provision. This paper aims to share these experiences and findings of research, and the impact it may have on the Sanitation MDG goals.

    Abstract Background: Increasing numbers of clinical teaching fellows are responsible for a significant proportion of undergraduate teaching nationally. Developing a regional community of practice can help overcome the isolation of these posts, with potential benefits for all involved.
    Context: A community of practice relies on the mutual engagement of people in a similar situation working towards a common goal. Working together and sharing resources enables teaching fellows to make the most of their post, which ultimately benefits those that they are teaching.
    Innovation: We developed a regional clinical teaching fellow community of practice in Bristol in 2010/11. Our community has continued to develop since completing our posts as clinical teaching fellows, and has provided a platform for new communities to develop amongst the groups of subsequent teaching fellows coming through. We encourage all regions who have clinical teaching fellows to develop a regional community of practice
    Implications: We encourage all regions who have clinical teaching fellows to develop a regional community of practice. We also encourage trainees to join TASME (Trainees in the Association for the Study of Medical Education), a new national community of practice for trainees involved in medical education.

    Abstract Aim: To explore patients' views on living with anaemia and undergoing blood transfusions in a day hospice.
    Methods: This was a qualitative study using semi-structured interviews. Ten patients who between them had received 90 transfusions were purposively sampled from the hospice day unit. The interviews were digitially recorded, transcribed anonymously, and the transcripts analysed using a phenomenological analysis framework.
    Findings: Tiredness was the most common symptom of anaemia. Participants liked attending the day hospice instead of hospital for their transfusions owing to differences in transport, parking, waiting time, and space to ask questions. The majority had no concerns about hospice transfusion and would be happy to return for further treatment.
    Conclusions: Haematology patients can have a good experience when undergoing blood transfusion at a day hospice. Hospices should perhaps offer this procedure more widely.

    Abstract Brassica crops have indeterminate growth and flower over an extended period of time. Harvested seed is therefore comprised of seed of varying degrees of physiological maturity and quality. Using population-based threshold models, broccoli (Brassica oleracea L. Group Italica), brussels sprouts (B. oleracea L. Group Gemmifera), red cabbage (B. oleracea L. Group Capitata), and rapeseed (B. napus L.) were characterized during seed development with respect to sensitivity to abiotic stress (reduced water potential) and shelf life. Using these models our data suggests that the physiological patterns of seed development are the same in all brassica crops we have tested to date. These population-based models can be used to provide a biological basis in which to evaluate cultural, postharvest and storage practices to ensure the production and maintenance of seed vigor.

    Abstract Endo-[beta]-mannanase is hypothesized to be a rate-limiting enzyme in endosperm weakening, which is a prerequisite for radicle emergence from tomato (Lycopersicon esculentum Mill.) seeds. Using a sensitive, single-seed assay, we have measured mannanase activity diffusing from excised tomato endosperm caps following treatments that alter the rate or percentage of radicle emergence. Most striking was the 100- to more than 10,000-fold range of mannanase activity detected among individual seeds of highly inbred tomato lines, which would not be detected in pooled samples. In some cases a threshold-type relationship between mannanase activity and radicle emergence was observed. However, when radicle emergence was delayed or prevented by osmoticum or abscisic acid, the initial increase in mannanase activity was unaffected or even enhanced. Partially dormant seed lots displayed a bimodal distribution of activity, with low activity apparently associated with dormant seeds in the population. Gibberellin- and abscisic acid-deficient mutant seeds exhibited a wide range of mannanase activity, consistent with their variation in hormonal sensitivity. Although the presence of mannanase activity in the endosperm cap is consistently associated with radicle emergence, it is not the sole or limiting factor under all conditions.
