Green Versus Brown Assets Under Stress: Who Hedges Energy and Market Risk?

Sustainable finance increasingly treats green assets as instruments for climate-risk hedging; however, it remains unclear whether they protect investors during energy-market shocks and financial-market stress or merely transmit different transition, equity-market, and growth risk...

Optimization of FDM process parameters for ABS components: Effects on printing time, part weight, and vibrational loss factor using Integrated TOPSIS-CoCoSo and decision tree approaches

Fused Deposition Modeling (FDM) has been widely studied for the manufacture of light-weight polymer components. However, the process parameter selection significantly effects the production efficiency, material consumption and vibration damping performance. In the present study,...

Effect of Omani Limestone Waste as a Reinforcing Agent on the Mechanical Properties of Scrap-Based Aluminum Matrix Composites

This paper analyzes the use of Omani limestone, collected from the mountain ranges of the Sultanate of Oman, a major global exporter of limestone, as a natural reinforcement to improve the mechanical properties of recycled aluminum alloys obtained from automotive engine cylinder...

Thermal Aging and Geometry-Driven Changes in Strength of 3D-Printed Polymers

The benefits of additive manufacturing (AM, i.e., 3D printing) have made it one of the most widely used and favored production techniques across a variety of industries. In the current study, the influence of geometry and thermal aging on the mechanical strength of AMed parts has...

Investor fears and cryptocurrency price crash risk

Purpose The study investigates the effect of investor fear on cryptocurrency crash risk, with emphasis on overall market sentiment and COVID-19-related fear. It also evaluates the relative performance of Google search-based measures compared to the economic policy uncertainty (EP...

Early Outcomes and Complications of Skin Graft Reconstruction for Complex Wounds at a Tertiary Hospital: A Single-Centre Study in Oman

Background: Complex wounds present significant reconstructive challenges owing to impaired healing, infections, and tissue loss. Skin grafting remains a widely used reconstructive technique; however, outcome data from the Gulf region are limited to a few studies. This study aimed...

Numerical Assessment of the Stamping Formability of SS304 Metallic Bipolar Plates with Side-Boss Parallel Flow Channels

Side-boss parallel channels can enhance reactant transport and water removal in proton exchange membrane fuel cells, but their local protrusions increase the forming difficulty of ultra-thin metallic bipolar plates. This study numerically investigates the single-step stamping for...
