Recovery of bitumen from tar sands by a thermally coupled fluidized-bed process [PDF]
, 1985 Tar sands, biomass, heavy oil, oil shale, and coal are considered to be the primary contributors to the emerging synfuel industry. On a global basis, Meyer and Fulton (1982) estimate the total heavy oil and bitumen resource to be more than 4 trillion ...

Biological Reviews, EarlyView.ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Investigation of Tar Properties for Tar Removal by Scrubbing
, 2010 A new concept to remove tar by scrubbing from biomass gasification gas is investigated. The concept is based on a system capable to remove the tars in two sequential stages: heavy tars are removed in a first hot absorber and the light tars (and water) are removed in a second, colder, absorber. The liquid stream contain light tars is recirculated to the

The Effect of Carbon Disclosure Quality on Green Bond Financing Cost
Business Strategy and the Environment, EarlyView.ABSTRACT Existing research on financing costs primarily focuses on traditional financial factors, such as credit ratings, and offers limited examination of non‐financial information. This study examines the impact of the quality of carbon information disclosure on financing costs using a fixed‐effects panel regression, based on data from 166 Chinese ...

Business Strategy and the Environment, EarlyView.ABSTRACT Rare earth elements (REEs) are critical inputs for low‐carbon technologies, yet their supply chains remain highly concentrated and vulnerable. Although diversification is widely promoted as a strategy to enhance supply chain resilience, its feasibility in strategic material systems remains limited.

Clinical Advances in Periodontics, EarlyView.Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...
