For improving the mechanical and thermal properties of polyurethanes based on glycidyl azide polymer (GAP), a series of polyurethane elastomers with two soft segments were prepared from hexamethylene diisocyanate (HDI) / (GAP) / (PPG) /TMP and isophorone diisocyanate (IPDI) / GAP/ PPG/ TMP formulation. The weight ratio of soft segments GAP/PPG in polyurethane samples is changed as following ord...

This deliverable describes the development of the gap analysis schema and correspond­ ing tool support. First a gap analysis framework was developed, thus eliciting and struc­ turing the relevant dimensions and corresponding attributes for future e-infrastructures into a formal schema. Then a stepwise procedure was developed for conducting the gap analyses, providing methods and metrics to iden...

temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...

Gaps created by falling trees (tree-fall gaps) are a natural disturbance in forest ecosystems. Understanding scale, pattern and the effect of gaps on regeneration is important to current and future forest management. The aim of this study was to determine the size, shape and the spatial pattern of tree-fall gaps and of associated regeneration. This study was carried out in three parcels (No.15,...
