AbstractBifidobacteria, the initial colonisers of breastfed infant guts, are considered as the key commensals that promote a healthy gastrointestinal tract. However, little is known about the key metabolic differences between different strains of these bifidobacteria, and consequently, their suitability for their varied commercial applications. In this context, the present study applies a constraint-based modelling approach to differentiate between 36 important bifidobacterial strains, enhancing their genome-scale metabolic models obtained from the AGORA (Assembly of Gut Organisms through Reconstruction and Analysis) resource. By studying various growth and metabolic capabilities in these enhanced genome-scale models across 30 different nutrient environments, we classified the bifidobacteria into three specific groups. We also studied the ability of the different strains to produce short-chain fatty acids, finding that acetate production is niche- and strain-specific, unlike lactate. Further, we captured the role of critical enzymes from the bifid shunt pathway, which was found to be essential for a subset of bifidobacterial strains. Our findings underline the significance of analysing metabolic capabilities as a powerful approach to explore distinct properties of the gut microbiome. Overall, our study presents several insights into the nutritional lifestyles of bifidobacteria and could potentially be leveraged to design species/strain-specific probiotics or prebiotics.

Presents the teaching experience of using scale models as a means for the presentation and manipulation of the first ideas by students in a Project of the Built Environment 1 course in a School of Architecture and Urban Design. Discusses, as its main theme, the possibilities of creation and representation of the first ideas by beginning students. We perceive that the difficulties that arise at the beginning of design activities become intertwined, in beginning students, with difficulties related to architectural representation. What is the role of different types of representation in architecture for beginner student? It was possible to obtain better results while "teaching experience" subverting the classic role of graphical representation exercises in a studio? The work raises questions about the teaching of architecture design and possible methodological repercussions that help the beginner of design practice in the development of their ideas. The paper begins by discussing issues related to the representation in architecture, both graphically and through scale models. Then presents a methodological proposal for the exercises in the studio, discussing the results reported. The synthesis of the project, through the model, allows a clearer analysis even for the inexperienced student in dealing with projectual constraints and the project itself, thus obtaining interesting results as well as process and as product. Analysis of the results shows that the application of the scale model as the main element of discussion and presentation of the first ideas for the realization of the project was quite fertile, given the conditions that the exercise was developed and which must be observed: the student is beginner in design practice - are their first experiences in Workshops Project; the creation of a culture on the theme worked is essential - the study of similar projects, visit to the site, the clarity of the instruments of labor; the constant presentation and critique of the object designed by both the student and his colleagues as the teacher - activity performed in all classes, in the various stages of development.

Educational Reconstruction

Informal learning environments such as exhibitions in museums and science centres have the potential to promote public engagement in the societally important fields of nanoscience and nanotechnology (NST). This study contributes to research-based development of an NST exhibition by mapping educational, communicational and museographical challenges in illustrating nanoscale science. For the methodological framework, the study employs a previously suggested model based on the Model of Educational Reconstruction. Potential visitors’ perspectives were analysed by reviewing research literature on NST learning, and by interviewing science centre visitors. On the basis of the results, the study suggests strategies for illustrating the nanoscale in an exhibition: ways of supporting visitors’ scale conceptualisation, presenting images and visualisations deliberately, and using scale models and macroscopic analogies. The study examines how the educational role of science centres may be enhanced by informing exhibition development with visitor-oriented research.

Growth Estimation

This paper estimates an enriched version of the mainstream medium-scale dynamic stochastic general equilibrium model, which features nonseparability between consumption and real money balances in utility and a systematic response of the policy rate to money growth. Estimation results show that money is a significant factor in the monetary policy rule. As a consequence, econometric analysis that omits money from Taylor rules may lead to biased estimates of the model parameters. In contrast to earlier studies that rely on small-scale models, the paper stresses the merits of using a sufficiently rich model. First, it delivers different results, such as the role of nonseparability between consumption and money in utility. Second, the rich dynamics embedded in the model allow us to explore the responses of a larger set of macroeconomic variables, making the model more informative on the effects of shocks and more useful for understanding the sources of business cycles. Third and most importantly, it reveals the possible pitfalls of relying on small-scale models when studying money’s role in business cycles.

Sulphide Production

This study concerns the role of sulphide production in the reduction of algal populations and proliferation of purple sulphur bacteria in primary waste stabilization ponds, and the effect of such changes on effluent quality and hydrogen sulphide odour release. Full-scale ponds in Israel were compared to laboratory-scale models fed with domestic wastewater at various organic and sulphate loads. The phenomenon occurred in ponds whose organic loads were between those normally thought appropriate to facultative and anaerobic ponds. Algae of the genus Chlamydomonas were most tolerant of sulphide in ponds, confirming previous in vitro studies. Populations of both photosynthetic groups in the models were related to surface BOD5 loading rates and influent sulphate and sulphide concentrations. Purple sulphur bacteria were unable to prevent all odour release, so situations where they proliferate should be avoided by redesign. Shifts from algal to purple sulphur bacterial dominance caused by increased sulphide concentrations under constant loads were not observed to affect adversely effluent quality in terms of BOD5 and COD.
