Degradation kinetics and lifetime prediction for polystyrene/nanocellulose nanocomposites
(2020-01-01)
Cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs) were incorporated into polystyrene (PS), and thermal stability and lifetime prediction of the nanocomposites were investigated for variable filler content (0.25, ...
Thermal degradation and lifetime estimation of poly(ether imide)/carbon fiber composites
(Sage Publications Ltd, 2015-02-01)
The thermal decomposition behavior of poly(ether imide) (PEI)/carbon fiber composites used in aeronautical field was studied using thermogravimetric analysis in an inert atmosphere, at several heating rates between 2 and ...
Thermal characterization and lifetime prediction of the PHBV/nanocellulose biocomposites using different kinetic approaches
(2020-09-01)
In the present study, biocomposite films from cellulose nanocrystals (CNCs) were obtained by the solution casting method. CNCs were isolated from pineapple crown using chemical treatments followed by sulfuric acid hydrolysis ...
Can measurement of the fluorescence lifetime of extracted blood PPIX predict atherosclerosis?
(Elsevier Science Bv, 2018)
In this work, fluorescence lifetime has been used to analyze protoporphyrin IX (PPIX) extracted from blood for diagnosing atherosclerosis. A total of 10 adult white male rabbits (New Zealand) were divided into the control ...

Distribution of Short-Term and Lifetime Predicted Risks of Cardiovascular Diseases in Peruvian Adults
(Wiley, 2015)
BACKGROUND: Short-term risk assessment tools for prediction of cardiovascular disease events are widely recommended in clinical practice and are used largely for single time-point estimations; however, persons with low ...
Effect of the microstructure on the lifetime of dental ceramics
(ELSEVIER SCI LTD, 2011)
Objectives. To evaluate the effect of the microstructure on the Weibull and slow crack growth (SCG) parameters and on the lifetime of three ceramics used as framework materials for fixed partial dentures (FPDs) (YZ - Vita ...
Model based strategies towards protein A resin lifetime optimization and supervision
(Elsevier Science, 2020-08-16)
The high cost of protein A resins drives the biopharmaceutical industry to maximize its lifetime, which is limited by several processes, usually referred to as resin aging. In this work, two model based strategies are ...
