Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

Voids size distribution in gelled waxy crude oil under dynamic and static cooling

Petroleum Research
Waxy crude oil is known for its high wax contents that can potentially result in gelling following sufficient cooling of the transportation line in the subsea bed at offshore fields.

Macaúba (Acrocomia aculeata) pulp oil ethylic biodiesel using lipase from Aspergillus oryzae: kinetic and process parameters

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Macaúba (Acrocomia aculeata), a native species from Brazilian biomes, has emerged as a sustainable alternative to vegetable oil production. Its fruit presents high oil yield (3–6 ton/ha), extracted from its kernel and pulp. While the kernel is suitable for food and cosmetics application, the pulp oil has been considered as a promising ...

Some New Results on the Flow of Waxy Crude Oils in a Loop

Interfaces and Free Boundaries, Mathematical Analysis, Computation and Applications, 2002
Summary: Waxy crude oils are characterized by a large concentration of paraffin (a mixture of heavy hydrocarbons). For sufficiently low temperatures paraffin is partly crystallized and crystals tend to form a structure that is stable below some critical stress.

Beyond the Reports: Cultural Pressures, Unheard Voices and the Climate Accountability Gap in Oil and Gas Sector Governance

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental governance in Nigeria's oil and gas sector remains central to global climate justice debates, yet persistent accountability failures continue to undermine meaningful environmental and social outcomes. Despite extensive regulatory frameworks, accountability in resource‐dependent contexts is frequently reduced to formal reporting ...

Climate Change, Strategic Orientation, and Green Innovation: Unpacking External and Internal Drivers in Competitive Contexts

Business Strategy and the Environment, EarlyView.
ABSTRACT Firms increasingly face political and societal pressures to pursue green strategies and sustainable innovation amid escalating climate change disruptions. Drawing upon contingency theory, institutional theory, and the natural resource‐based view, this article examines external (stakeholder pressures) and internal (environmental culture ...
