Abstract

Transcritical flow of a stratified fluid past a broad localised topographic obstacle is studied analytically in the framework of the forced extended Korteweg--de Vries (eKdV), or Gardner, equation. We consider both possible signs for the cubic nonlinear term in the Gardner equation corresponding to different fluid density stratification profiles. We identify the range of the input parameters: the oncoming flow speed (the Froude number) and the topographic amplitude, for which the obstacle supports a stationary localised hydraulic transition from the subcritical flow upstream to the supercritical flow downstream. Such a localised transcritical flow is resolved back into the equilibrium flow state away from the obstacle with the aid of unsteady coherent nonlinear wave structures propagating upstream and downstream. Along with the regular, cnoidal undular bores occurring in the analogous problem for the single-layer flow modeled by the forced KdV equation, the transcritical internal wave flows support a diverse family of upstream and downstream wave structures, including solibores, rarefaction waves, reversed and trigonometric undular bores, which we describe using the recent development of the nonlinear modulation theory for the (unforced) Gardner equation. The predictions of the developed analytic construction are confirmed by direct numerical simulations of the forced Gardner equation for a broad range of input parameters., Comment: 34 pages, 24 figures

Abstract

We develop modulation theory for undular bores (dispersive shock waves) in the framework of the Gardner, or extended Korteweg--de Vries, equation, which is a generic mathematical model for weakly nonlinear and weakly dispersive wave propagation, when effects of higher order nonlinearity become important. Using a reduced version of the finite-gap integration method we derive the Gardner-Whitham modulation system in a Riemann invariant form and show that it can be mapped onto the well-known modulation system for the Korteweg--de Vries equation. The transformation between the two counterpart modulation systems is, however, not invertible. As a result, the study of the resolution of an initial discontinuity for the Gardner equation reveals a rich phenomenology of solutions which, along with the KdV type simple undular bores, include nonlinear trigonometric bores, solibores, rarefaction waves and composite solutions representing various combinations of the above structures. We construct full parametric maps of such solutions for both signs of the cubic nonlinear term in the Gardner equation. Our classification is supported by numerical simulations., Comment: 25 pages, 24 figures, slightly revised and corrected version

32. Managing plastics: uses, losses and disposal

Author

Clift, R., Baumann, H., Murphy, R. J., and Stahel, W. R.

Abstract

It has long been recognised that plastic objects released into the environment have harmful impacts on wildlife. Public realisation that plastic pollution is a major global environmental problem is more recent and has been sudden, sparked by publication of an analysis of the flows of polluting plastics into the environment and the accumulated stocks of polluting waste, particularly in the oceans.1 This contribution aims first to provide an introduction to the history and uses of plastics in the economy and, secondly, to set out the routes by which plastics leak from the economy into the environment in order to inform development of possible strategies to alleviate the problem of plastic pollution.

36. TRANSPLANTATION OF STORED ALLOGENEIC BONE MARROW IN DOGS SELECTED BY HISTOCOMPATIBILITY TYPING

Author

Epstein, R B, Storb, R, Clift, R A, and Thomas, E D

Abstract

Allogeneic canine marrow preserved at —80 C in 10 dimethyl sulfoxide was used for transplantation in unrelated dogs following 1200 R whole body irradiation. Lymphocytes of donors and recipients were typed with four canine cytotoxic isoantisera. The results in 10 recipients that were matched with their donors were compared to the results in 10 mismatched recipients. A successful marrow graft was observed in all 10 matched recipients and in 9 of 10 mismatched recipients. Graft rejection occurred in 2 of 10 matched and 7 of 10 mismatched recipients. The matched recipients survived significantly longer than did the mismatched ones (P< 0.005). Two of the matched dogs are alive more than 135 and 160 days after transplantation. The cryopreservation of the marrow did not appear to lessen its ability to produce lethal graft-versus-host disease. The results d emonstrate the importance of histocompatibility matching in successful grafting with cryopreserved marrow

Abstract

Environmental life cycle assessment (LCA) has developed fast over the last three decades. Today, LCA is widely applied and used as a tool for supporting policies and performance-based regulation, notably concerning bioenergy. Over the past decade, LCA has broadened to also include life cycle costing (LCC) and social LCA (SLCA), drawing on the three-pillar or ‘triple bottom line’ model of sustainability. With these developments, LCA has broadened from merely environmental assessment to a more comprehensive life cycle sustainability assessment (LCSA). LCSA has received increasing attention over the past years, while at the same time, its meaning and contents are not always sufficiently clear. In this chapter, we therefore addressed the question: what are LCSA practitioners actually doing in practice? We distinguished two sub-questions: which definition(s) do they adopt and what challenges do they face? To answer these questions, LCSA research published over the past half decade has been analysed, supplemented by a brief questionnaire to researchers and practitioners. This analysis revealed two main definitions of LCSA. Based on these two definitions, we distinguished three dimensions along which LCSA is expanding when compared to environmental LCA: (1) broadening of impacts, LCSA = LCA + LCC + SLCA; (2) broadening level of analysis, product-, sector- and economy-wide questions and analyses; and (3) deepening, including other than just technological relations, such as physical, economic and behavioural relations. From this analysis, it is clear that the vast majority of LCSA research so far has focused on the ‘broadening of impacts’ dimension. The challenges most frequently cited concern the need for more practical examples of LCSA, efficient ways of communicating LCSA results and the need for more data and methods particularly for SLCA indicators and comprehensive uncertainty assessment. We conclude that the three most crucial challenges to be addressed first are developing quantitative and practical indicators for SLCA, life cycle-based approaches to evaluate scenarios for sustainable futures and practical ways to deal with uncertainties and rebound effects.
