A study of the cure kinetics a one-part water-scavenging silicone elastomer was carried out under conditions controlled humidity and temperature using rectangular bars subjected to oscillatory torsional shear. Characteristic times were obtained from Hsich model fits storage modulus evolution. modified Arrhenius-style is proposed that accounts for both dependence proportionality between rate con...

HIV persistence in patients undergoing antiretroviral therapy is a major impediment to the cure of HIV/AIDS. The molecular and cellular mechanisms underlying HIV persistence in vivo have not been fully elucidated. This lack of basic knowledge has hindered progress in this area. The in vivo analysis of HIV persistence and the implementation of curative strategies would benefit from animal models...

depth of cure of composite material is restricted and it depends on many parameters such as thickness. the aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (quixfil and photocore) in different thicknesses, when cured for 60 seconds.the vickers microhardness measurements were made for each side of the top irradiated surfaces of 1,2,3,4,5,6,...

statement of problem: for many years, application of the composite restoration with a thickness less than 2 mm for achieving the minimum polymerization contraction and stress has been accepted as a principle. but through the recent development in dental material a group of resin based composites (rbcs) called bulk fill is introduced whose producers claim the possibility of achieving a good rest...

Highly reactive thermosets are currently expanding the processability of high-performance structures for transportation industry. The short polymerization time makes it a suitable process to replace metallic with polymer matrix-based composite materials. resin characterization is fundamental step obtain properties and associated constitutive models, which required design optimize manufacturing ...

When analyzing time-to-event data, it often happens that some subjects do not experience the event of interest. Survival models take this feature into account (called ‘cure models’) have been developed in presence covariates. However, nonparametric cure with covariates, current literature, cannot be applied when follow-up is insufficient, i.e., right endpoint support censoring time strictly sma...
