Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds

Fire and Materials, EarlyView.
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product (FTP ...

Design Approaches for Oxygen Reduction Systems for Warehouse Storage Applications

Fire and Materials, EarlyView.
ABSTRACT Oxygen reduction systems (ORS) are protection systems, with a design protection objective to limit fire spread beyond the point of ignition. Research has shown that the prescriptive design methods, in VdS 3527, EN 16750, and ISO 20338, are not appropriate as prescriptive design methods as they result in insufficient protection levels.

Pollinator risks and recovery from air pollutant interactions during the fossil‐fuel transition

Frontiers in Ecology and the Environment, EarlyView.
By altering the composition and concentration of floral scents, air pollutants such as ozone (O3) and nitrogen oxides (NOx) disrupt the ability of insect pollinators to locate flowers, threatening biodiversity and crop production. We examine the impact of these pollutants on pollinator performance and evaluate the short‐ and long‐term consequences of ...

Farm‐Level Greenhouse Gas Balance of Commercial Coffee Production in Minas Gerais, Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Coffee production is considered a potential contributor to climate change mitigation due to its perennial biomass and carbon storage capacity. However, empirical assessments of greenhouse gas (GHG) balances at the farm level remain limited for commercial coffee systems.

Rethinking a positive‐sum game: US FDI location decisions in the presence of Chinese FDI

Global Strategy Journal, EarlyView.
Abstract Research Summary This study examines how rising Chinese outbound foreign direct investment (OFDI) in third‐country markets shapes US MNEs' foreign direct investment location decisions amid escalating US–China geopolitical rivalry. US firms initially benefit from complementary co‐location dynamics, as Chinese OFDI—particularly in infrastructure—
