Sound Absorption Coefficient in Natural Flax Fibers

open access: yes, 2010
There are two methods of measuring the amounts of sound absorbed by various materials. One is the reverberation method, in which a specimen of the material to be tested is mounted on the walls of a reverberation chamber and the coefficient of absorption is deduced from the effect, which the presence of the specimen has on the rate of decay of sound in ...

Learner emotions and performance in hypercasual VR games with adaptive AI difficulty

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Hypercasual virtual reality games (HVRGs) are widely regarded as cost‐effective tools for rapid skill acquisition, yet the mechanisms that optimise their effectiveness and user acceptance remain insufficiently explored. This mixed‐methods empirical study investigates how playful emotions, characterised by engagement, enjoyment and anxiety ...

The Strategic Role of Waste Inventories in Industrial Symbiosis: A Simulation‐Based Perspective on Performance and Resilience of Industrial Symbiosis Networks

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Ensuring the resilience of industrial symbiosis networks (ISNs) has emerged as a key concern in the literature. However, existing studies focus on network‐level strategies, neglecting the potential benefits derived from strengthening the links between symbiotic partners.

From Ecosystem Threats to Balance Sheets: Biodiversity Risks Exposure and Corporate Cash Policies

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how firms strategically respond to biodiversity risk by examining their cash holding decisions. Using firm‐level data from China, we find that firm‐level biodiversity risk exposure significantly increases corporate cash holdings.

Advancing Sustainable Development in Manufacturing: A Strategic Framework for Overcoming Green–Lean Implementation Barriers

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Manufacturing's transition to sustainable development depends on integrating green with lean under credible environmental policy and stakeholder engagement. Although benefits are well established, the literature underspecifies implementation barriers and their prioritisation. This study identifies, structures, and prioritises barriers to green–

Green Innovation and Firm Efficiency: The Role of Institutional Quality in Italian High‐Tech Manufacturing Sectors

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The aim of this research is to verify whether institutional quality affects the relationship between green innovation and firm efficiency within the high‐tech manufacturing sectors. To estimate jointly the parameters of a stochastic frontier and the coefficients of a model explaining technical inefficiency, we employed the one‐step estimation ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
