Non-metallic brush seals for gas turbine bearings [PDF]

open access: yes, 2004
A non-metallic brush seal has been developed as an oil seal for use in turbomachinary. Traditionally labyrinth-type seals with larger clearances have been used in such applications. Labyrinth seals have higher leakage rates and can undergo excessive wear

Extrapancreatic actions of incretin-based therapies on bone in diabetes mellitus [PDF]

open access: yes, 2015
Diabetes mellitus is correlated with modifications in bone microarchitectural and mechanical strength, leading to increased bone fragility. The incretin hormones, with a classical effect to increase insulin secretion following food ingestion, are now

Effect of stitch and biaxial yarn types on the impact properties of biaxial weft knitted textile composites

open access: yesScience and Engineering of Composite Materials, 2013
Within the scope of experiments, the effects of stitch yarn type, such as aramid, glass, and nylon, and biaxial, warp, and weft yarn type, such as aramid and glass, on biaxial weft knitted (BWK) composites were investigated.

On the Network Strength of Meta-Aramid Fiber Suspension and Its Relationship to Formation

open access: yesAdvances in Polymer Technology, 2022
Because of poor surface hydrophilicity, meta-aramid fibers readily form flocs by intertwining or interlacing, and this severely affects the uniformity of meta-aramid paper.
