Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Diesel Engine Injector Faults Detection Using Acoustic Emissions Technique

open access: yes, 2010
This study focuses on investigation of the method of identifying injector faults in a JCB 444T2 diesel engine using acoustic emission (AE) technique. Different kinds of injector faults were seeded in the four-cylinder, four-stroke, and turbo-engine. Then,

Reframing FDI Motivations Through OLIP: Explaining Private Engagement for Sustainable Development in PPPs

open access: yesSustainable Development, EarlyView.
ABSTRACT The drivers of firms' participation in fragile markets have become increasingly complex. Under such conditions, the conventional explanation focusing on incentives within the OLI framework—ownership, location, and internalization advantages—proves insufficient.

Undiversity, inequity, and exclusion in supply chains: The unintended fallout of economic sanctions and consumer boycotts

open access: yesProduction and Operations Management, EarlyView., 2023
Abstract Economic sanctions and consumer boycotts are common tools to punish organizations for undesirable behavior and attempt to coerce them to change their actions. However, these tools occasionally spill over beyond the intended recipients and affect guiltless supply chain members, jeopardizing the principles of diversity, equity, and inclusion in ...
