The Canadian Journal of Chemical Engineering, EarlyView.The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Optimal dividends for a NatCat insurer in the presence of a climate tipping point
Canadian Journal of Statistics, EarlyView.Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.

Ngos' Contributions to Innovation: Innovation Enablers or Lead Innovators?
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study explores how non‐governmental organisations (NGOs) engage with innovation processes. Drawing on a comparative case study of two NGOs working in water sustainability, the paper analyses NGO involvement across seven stages of the innovation process.

Up to now we have discussed ocean currents only in the surface layer, i.e. above the main or permanent thermocline. This layer constitutes approximately 10% of the volume of the World Ocean. It was amply demonstrated that the major current systems in the upper strata are generated by atmospheric forces.

One of the most characteristic features of the great oceans is the presence of what have been aptly termed ‘deeps,’ enormous depressions in the ocean bottoms. Having in my “Evolution of Earth Structure” discussed their distribution and probable origin, I was naturally attracted by the notice in Nature of the surveys of the vessel “Edi” and the cable ...

Deep ocean influence at ocean boundaries
2016The continental slope has an important influence on ocean dynamical variability, the steep slopes leading to rapid signal propagation and a smoothing of pressure variability along the slope. As a result, pressure variations tend to be smaller than nearby sea level variability would suggest, and mesoscale variability is suppressed.

Modeling ocean deep convection
Ocean Modelling, 2004Abstract The goal of this study is to assess models for Deep Convection with special emphasis on their use in coarse resolution ocean general circulation models . A model for deep convection must contain both vertical transport and lateral advection by mesoscale eddies generated by baroclinic instabilities.

The concept for a large diameter inflatable pipe for open ocean upwelling and OTEC applications is developed. The inflatable pipe offers the advantages of ease of installation and non-catastrophic buckling. Pipe geometry and inflation-induced loads are analyzed, and a preliminary bending analysis is performed. Model tests are compared with the analysis,

ABSTRACT A 3 mi11ion ton per year, three metal, vertically integrated, ocean exploration, mining, transportation and ore-processing and metal-marketing system is defined and the capital and operating costs estimated in 1980 U.S. dollars. A basic return-on-investment "pay-out" analysis model is presented with several
