Changes in metal leachability through stimulation of iron reducing communities within waste sludge

Bioreduction of ferric iron-rich wastes is a rapidly emerging technology for the extraction/ recovery of metals from low-grade ores and metallurgical wastes. However, despite studies being successful, they have only been demonstrated at laboratory scale and issues relating to economic, industrial scale application have yet to be studied. Using bioreduction as a pre-treatment to increase recovery yield is a relatively new concept. This study examines the biostimulation of microbial communities to induce bioreduction of metalliferous sludge and the effect that this has on the leachability of metals from the waste using dilute sulphuric acid. Data shows an increase in both zinc and copper leachability after bioreduction, with maximum six fold and eleven fold increase (compared to pre-treatment) in the amount of zinc and copper leached respectively.</jats:p

The Eucharist and planetary wellbeing: Norman Pittenger's process theology of the Eucharist for a sacramental ecotheology

This dissertation explores relationships between Christian communities, ecological theology, food and meal patterns, and planetary wellbeing amid changing climates in the Plantationocene. The thesis is that a process theology of the Eucharist provides a framework for Christian sacramental theology to respond to the dynamic conditions of food amid changing climates on Earth by prioritizing processes of restoring and sustaining communion with God and all our creaturely kindred in ecological wellbeing. This dissertation presents and develops the process theology of Norman Pittenger, a Christian process theologian and theological interpreter of Alfred North Whitehead. By critically retrieving Norman Pittenger’s process ecclesiology, I aim to encourage Christian process theology to develop theological perspectives of sacramentality as celebrated through the church and Christian life for the wellbeing of the planet. In addition to developing a process theology of the Eucharist, this dissertation also lays foundations for a broader process theology of meals that seeks to respond to the dynamic conditions of food in changing climates in modernity. Weaving together the work of Theodore Walker, Jr., William T. Cavanaugh, Catherine Keller, Nick Estes, S. Yael Dennis, Filipe Maia, Roxanne Dunbar-Ortiz, Donna Haraway, Anna Tsing, and William Cronon, I critique modernity as a paradigm of commodifying relationships that depend on isolating people from one another and dismembering ecosystems for capital profit. I identify modernity’s meals as products of and contributors to anthropogenic climate change in the Plantationocene that depend upon processes of commodification and dismemberment of ecological bodies. How humans eat matters for the wellbeing of the world. For many Christians, the Eucharist meal is central to relationship with God and other people. The particularities of local eucharistic communities influence how the church experiences eucharistic relationships with God. Likewise, experiences of the Eucharist influence the particularities that characterize any local church. This dissertation contends that encountering cosmic Love in the Eucharist meal transforms the church to reveal and enact love in all our meals, promoting planetary wellbeing through food justice and ecological health

The role of the basic state in the ENSO-monsoon relationship and implications for predictability

The impact of systematic model errors on a coupled simulation of the Asian Summer monsoon and its interannual variability is studied. Although the mean monsoon climate is reasonably well captured, systematic errors in the equatorial Pacific mean that the monsoon-ENSO teleconnection is rather poorly represented in the GCM. A system of ocean-surface heat flux adjustments is implemented in the tropical Pacific and Indian Oceans in order to reduce the systematic biases. In this version of the GCM, the monsoon-ENSO teleconnection is better simulated, particularly the lag-lead relationships in which weak monsoons precede the peak of El Nino. In part this is related to changes in the characteristics of El Nino, which has a more realistic evolution in its developing phase. A stronger ENSO amplitude in the new model version also feeds back to further strengthen the teleconnection. These results have important implications for the use of coupled models for seasonal prediction of systems such as the monsoon, and suggest that some form of flux correction may have significant benefits where model systematic error compromises important teleconnections and modes of interannual variability

Empirical evidence for unique hues?

Red, green, blue, yellow, and white have been distinguished from other hues as unique. We present results from two experiments that undermine existing behavioral evidence to separate the unique hues from other colors. In Experiment 1 we used hue scaling, which has often been used to support the existence of unique hues, but has never been attempted with a set of non-unique primaries. Subjects were assigned to one of two experimental conditions. In the "unique" condition, they rated the proportions of red, yellow, blue, and green that they perceived in each of a series of test stimuli. In the "intermediate" condition, they rated the proportions of teal, purple, orange, and lime. We found, surprisingly, that results from the two conditions were largely equivalent. In Experiment 2, we investigated the effect of instruction on subjects' settings of unique hues. We found that altering the color terms given in the instructions to include intermediate hues led to significant shifts in the hue that subjects identified as unique. The results of both experiments question subjects' abilities to identify certain hues as unique

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. I: Mean response and interannual variability

The impact of doubled CO2 concentration on the Asian summer monsoon is studied using a coupled ocean-atmosphere model. Both the mean seasonal precipitation and interannual monsoon variability are found to increase in the future climate scenario presented. Systematic biases in current climate simulations of the coupled system prevent accurate representation of the monsoon-ENSO teleconnection, of prime importance for seasonal prediction and for determining monsoon interannual variability. By applying seasonally varying heat flux adjustments to the tropical Pacific and Indian Ocean surface in the future climate simulation, some assessment can be made of the impact of systematic model biases on future climate predictions. In simulations where the flux adjustments are implemented, the response to climate change is magnified, with the suggestion that systematic biases may be masking the true impact of increased greenhouse gas forcing. The teleconnection between ENSO and the Asian summer monsoon remains robust in the future climate, although the Indo-Pacific takes on more of a biennial character for long periods of the flux-adjusted simulation. Assessing the teleconnection across interdecadal timescales shows wide variations in its amplitude, despite the absence of external forcing. This suggests that recent changes in the observed record cannot be distinguished from internal variations and as such are not necessarily related to climate change

Verb use in aphasic and non-aphasic personal discourse: What is normal?

Sentence and discourse analysis research provides evidence of both impaired and intact ability in verb production in aphasia, based on comparisons made within aphasic subtypes, and between aphasic and control speakers. Comparisons are complicated due to variation in elicitation tasks and genre, participant sample size, and aphasia subtype, as well as methodological differences in determining fluency. In this study, we examined the impact of aphasia on speakers’ capacity to talk about their quality of life, applying three analytical methods to 58 speakers’ discourse (29 predominantly fluent aphasic speakers; 29 non-aphasic speakers). Both speaker groups produced similar quantity, weight, and type of verbs, with substantial overlap in verb tokens. Relational, material and mental verbs were prevalent. Aphasic speakers had significantly lower predicate argument structure scores, and produced significantly more 0 argument structures, more [Aux+0] constructions, fewer 1 argument structures in general and fewer 1 argument structures with clausal embedding, compared to non-aphasic speakers. This study provides evidence for intact (semantic weight and type) and impaired (PAS) verb production in aphasia. The heterogeneity within both participant samples challenges assumptions of normality and typicality
