Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

Archaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Impacts of Inventory Credit, Input Supply Shops and Fertilizer Micro-Dosing in the Drylands of Niger [PDF]

This study investigates the impacts of access to inventory credit (warrantage), input supply shops, fertilizer micro-dosing demonstrations, and other factors on farmers' use of inorganic and organic fertilizer in Niger, and the impacts on crop yields. We

Green‐lighting biofuels from microalgal lipids: A review of strategies to integrate stress into continuous cultures

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The vision of using microalgae to obtain organic chemicals in a carbon‐neutral manner is intriguing. It promises to produce various substances including biofuels by photosynthesis, without competing with agricultural land. Processes have been established whereby microalgae undergo a growth phase followed by a stress phase, which induces lipid ...

‘Let's talk about the weather’: The activist curriculum and global climate change education

British Educational Research Journal, EarlyView.
Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...

Is the well‐known phrase ‘small is beautiful’ true of small transnational education institutions?

British Educational Research Journal, EarlyView.
Abstract The purpose of this research is to consider the potential attractiveness of operating a small international branch campus (IBC). Drawing upon resource‐based and legitimacy theories, we examine the strengths, weaknesses, opportunities and threats associated with the business model that is based on having a small institution size.

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.
