Physiological Assessment with iFR prior to FFR Measurement in Left Main Disease

Cardiovascular Intervention and Therapeutics
Despite guideline-based recommendation of the interchangeable use of instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) to guide revascularization decision-making, iFR/FFR could demonstrate different physiological or clinical outcomes ...

Comparison of Different Diastolic Resting Indexes to iFR: Are They All Equal? [PDF]

Journal of the American College of Cardiology, 2017
BACKGROUND Pressure measurement for the duration of the wave-free period (WFP) is considered essential for resting-state physiological assessment of coronary stenosis severity using the instantaneous wave-free ratio (iFR).

Preparation of a Reactive Phosphorus/nitrogen-Based Intumescent Flame Retardant Coating for Cotton Fabrics

Journal of Natural Fibers, 2023
This study focuses on the synthesis of a reactive phosphorus-/nitrogen-based intumescent flame retardant (IFR) agent using diethyl phosphite, urea, and glutaraldehyde through Kabachnik-Fields reaction. We further studied the potential applications in IFR

IFRS

Foundations and Trends® in Accounting, 2021
This monograph reviews the academic literature on market outcomes, reporting practices and the political economy behind the global use of International Financial Reporting Standards (IFRS). We start with a conceptual discussion of expected benefits and costs of an international harmonization of accounting regulation and explain why predictions on ...

Synergistic effect of graphene oxide and boron-nitrogen structure on flame retardancy of natural rubber/IFR composites

Arabian Journal of Chemistry, 2020
In this paper, GO-BN(graphene oxide grafted boron nitride) was synthesized from graphene oxide and boron nitride by silane coupling agent KH550. Furthermore, GO-BN and intumescent flame retardant (IFR) were added into natural rubber (NR) simultaneously ...
