Field emission measurements of solid fuel stoves in Yunnan, China
No full textEmission factors of carbon monoxide (CO), particulate matter (PM2.5), organic carbon (OC), and elemental carbon (EC), as well as combustion efficiency and particle optical properties were measured during 37 uncontrolled cooking tests of residential stoves in Yunnan Province, China. Fuel mixtures included coal, woody biomass, and agricultural waste. Compared to previously published emission measurements of similar stoves, these measurements have higher CO and PM2.5 emission factors. Real-time data show two distinct burn phases: a devolatilization phase after fuel addition with high PM2.5 emissions, and a solid-fuel combustion phase with low PM2.5 emissions. The average emission factors depend on the relative contributions of these phases, which are affected by the services provided by the stoves. Differences in stove and fuel characteristics that are not represented in emission inventories affect the variability of emission factors much more than do the type of solid fuel or stove. In developing inventories with highly variable sources such as residential solid-fuel combustion, we suggest that (1) all fuels should be accounted for, not just the primary fuel; (2) the household service provided should be emphasized rather than specific combinations of solid fuels and devices; and (3) the devolatilization phase should be explicitly measured and represented.
This work also advances the development of portable sampling instruments for climate-relevant emission characterization with regard to usability, reliability, and accuracy.Submission original under an indefinite embargo labeled 'Open Access'.

Improving research methods teaching and learning in politics and international relations: a ‘Reality Show’ approach
No full textStudent dissatisfaction with undergraduate research methods courses in politics and international relations is common across the sector. We suggest that methods teaching suffers from an unhealthy disassociation between research in theory – which we call ‘method acting’ – and research in practice. Our critical interviews with eminent researchers expose the compromises professional researchers make when designing their research. Students appreciate these insights when combined with first-hand research opportunities. We call this approach a ‘reality show’. Our analysis based on survey data and students’ evaluations of our approach suggests that these aids can provide an effective resource to improve teaching and learning of research method

Characterisation of Cryptosporidium growth and propogation in cell free environments
No full textCryptosporidium is an enteric parasite that has a global impact on the health and survival of millions of people and animals worldwide. The resistant oocyst stage of the organism's life cycle is excreted in the faeces of infected animals and humans and can contaminate sources of drinking water. Cryptosporidium currently represents the major public health concern of water utilities in developed nations as the oocysts produced by Cryptosporidium are extremely hardy, easily spread via water, resistant to chlorine and are difficult to inactivate or remove from water intended for consumption without the use of filtration.
Recent developments in the in vitro cultivation have revealed that C. parvum can complete its life cycle in media devoid of host cells, which highlights the paucity of knowledge about the developmental biology of this parasite. This finding supports other biological and phylogenetic analysis suggesting that Cryptosporidium has a closer affinity with gregarines than with the coccidia. This thesis investigates the growth and propagation of Cryptosporidium in cell free environments.
A current limitation of host cell-free cultivation is the difficulty involved in visualising the life-cycle stages as they are very small in size and morphologically difficult to identify and dispersed throughout the media. This is in contrast to conventional cell culture methods for Cryptosporidium, where it is possible to focus on the host cells and view the foci of infection on the host cells. Three specific and three non-specific techniques for visualising C. parvum life-cycle stages in cell-free culture were compared; antibody staining using anti-sporozoite and anti-oocyst wall antibodies (Sporo-Glo™ and Crypto Cel), fluorescent in-situ hybridization (FISH) using a Cryptosporidium specific rRNA oligonucleotide probe and the non-specific dyes; texas red, carboxyfluorescein diacetate succinimidyl ester (CFSE) and 4,6’ diamino-2-phenylindole dihydrochloride (DAPI). Results revealed that a combination of Sporo-Glo™ and Crypto Cel staining resulted in easy and reliable identification of all life cycle stages.
This thesis reports for the first time the completion of the life cycle of C. hominis in cell-free culture and multiplication of the parasite via qPCR. Individual life cycle stages were characterised using Cryptosporidium-specific antibody staining (Sporo-GloTM) and fluorescent in situ hybridisation (FISH) staining on cultures inoculated with excysted oocysts and purified sporozoites. In both cultures, C. hominis successfully proliferated and completed its life cycle, however development in cultures inoculated with purified sporozoites lagged behind cultures inoculated with excysted oocysts. Some novel findings of the study include the visualisation of pairing and multiple associations between various developmental stages in a process similar to syzygy and the formation of Cryptosporidium stages (trophozoites and meronts) inside the oocysts without excystation. qPCR analysis revealed a 5-6-fold amplification of parasite DNA. Future studies are required to improve the amplification of the parasite.
Chapter 5 describes the complete development of all life cycle stages of Cryptosporidium parvum (cattle genotype) in water. This is the first report in which Cryptosporidium is shown to develop and complete its life cycle in water. Amplification of parasite numbers in water was quantified using oocyst counts and quantitative PCR (q-PCR). Daily monitoring by microscopy revealed that some oocysts, when placed in tap or rain water and incubated at 4, 15, 24 and 37°C, would excyst, releasing sporozoites resulting in continuation of the life cycle and production of new oocysts. Manual oocyst counts and qPCR analysis at days 0, 3, 6, 9 and12, when compared with the initial inoculum, showed a small but significant increase in oocyst numbers and oocyst equivalents, respectively.
A study was also conducted to determine if meront and merozoite life cycle stages derived from C. parvum oocysts incubated in rain water at 24°C were infective to neonatal ARC/Swiss mice. Each mouse was inoculated with approximately 25,000 meronts and merozoites, meronts were counted as ‘1’ stage. An estimated 1.1 x106 oocysts were recovered from 6 mice, therefore on average of 183,333 oocysts per mouse was recovered. This represents a 7.3 fold increase from the number of stages, which were inoculated into the mice. This study provided some evidence that meront and merozoite life cycle stages are capable of causing infection in neonatal mice. This is the first report of life cycle stages of Cryptosporidium other than the oocyst causing infection, however further research is required to confirm this.
The finding of this thesis will greatly assist in our understanding of the developmental biology of Cryptosporidium, its position within the Apicomplexa and its relationship to gregarine protozoa
