This article forms pan of an ongoing study of the coal and coalbed methane resource potential of northwestern British Columbia. Other areas under study include the Bower basin coalfield, Telkwa coalfield and Tertiary coalfields of the Bulkley Valley. Tertiary sediments survive in many major watersheds in British Columbia. The sediments are generally not well consolidated, poorly exposed and the...

Upshot: The target article defends the fundamental role of circularity for systems sciences and the necessity to develop a conceptual and methodological approach to it. The concept of circularity, however, is multifarious, and two of the main challenges in this respect are to provide distinctions between different forms of circularities and explore in detail the roles they play in organizations...

The city of Manaus has numerous waterways in its urban perimeter, and, despite this, there is a shortage measures aimed at protecting water resources that generated occupations very close to the riverbeds. This work aims characterize watershed an area and map areas subject flooding around Franceses Stream. methodology applied involved obtaining topographic thematic information such as morpholog...

The plankton fauna of the state of Piauí, Northeastern Brazil, especially in the Parnaíba basin, is still poorly known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports. Thus, this paper presents data from samples taken recently from different water bo...

I begin by highlighting the importance of the step size in the induction step of the sorites paradox. A careful analysis reveals that the step size can be characterised as a proper instance of the concept very small. After having accurately described the structure of sorites-susceptible predicates, I argue that the structure of the induction step in the Sorites Paradox is inherently circular. T...

If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own re...

The Circular Economy (CE) is heralded as an important concept with the potential to guide businesses and society toward a more sustainable future. However, while collaboration widely accepted play central role in advancing circularity, little known about how organizations effectively work together achieve these outcomes. This particularly problematic given that any shift requires systematic app...

The evolution toward sustainable mining can be achieved by implementing circular economies (CEs), and one way forward is via product-service systems (PSSs). However, applying PSSs in the industry an area with little extant research. We seek to contribute CE sustainability research proposing a model which companies achieve circularity through their suppliers: something has not yet been explored....

Material efficiency is a key element of new thinking to address the challenges of reducing 12 impacts on the environment and of resource scarcity, whilst at the same time meeting service and 13 functionality demands on materials. Directly related to material efficiency is the concept of the 14 Circular Economy, which is based on the principle of optimising the utility embodied in materials 15 a...
