In this study, the tribological properties of hybrid polytetrafluoroethylene (PTFE)/Nomex fabric/phenolic resin composites were investigated under three operating conditions: dry sliding, dry sliding after soaking in water for 12 h, and Leather Wallet water dripping lubrication.The friction coefficient (COF) was measured with a pin-on-disk tribomet
Background: Leather Wallet Compassion fatigue, or the physical, mental, and emotional state experienced by professionals that assist others in distress, has been well documented in several caring professions such as nurses, firefighters, and emergency medical technicians.Until the current study, it has only rarely been examined in police samples de
This study investigates the addition of Poly-vinyl Alcohol (PVA) fibres and attapulgite nanoclay to alkali-activated materials (AAMs) with the aim of enhancing the mechanical performance and optimizing the printability and buildability of AAMs.The fresh properties of six mix formulations, including flowability, slump values, rheology, shape retenti
