Achieving Sustainable Development Goals Through Social Life Cycle Assessment: A Case Study of Portuguese Forest Wood Supply Chains

Sustainable Development, EarlyView.
ABSTRACT Social considerations are often overlooked in efforts to achieve sustainable development, despite being critical for building equitable and resilient global value chains. This study addresses this gap by applying a social life cycle assessment to three key Portuguese forest wood supply chains—uncoated woodfree paper, natural cork stoppers, and

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
