Introduction: The aim of this study was to evaluate the influenceof different light curing systems and curing times on the micro-hardness of aresin modified glass ionomer. Methods: Forty two samples of ResinModified Glass Ionomer (RMGI) were prepared using stainless steel cylindrical mold(8 × 2 mm) and randomly divided into six groups of seven. Three groups werecured with a Quartz Tungsten Halo...

Conditions of adhesive cure process play a very important role in the quality of adhesive joints. It is known that the cure stage of adhesives correlates with the glass transition temperature and strength of adhesion. The objective of our present work was to quantitatively characterize cure of the adhesives with acoustic method. Pulse-echo mode was used for the study. Changes in acoustic parame...

One of the decisive factors in obtaining the desired properties in coatings is their complete curing, which necessitates the study of kinetics of curing. In recent years, many studies have been conducted on the use of polyhedral oligomeric silsesquioxane (POSS) in coatings. Creating functional groups on POSS and using it in formulation can create new or improve the properties of coatings. I...

BACKGROUND Some syphilis patients remain in a serologically active state after the recommended therapy. We currently know too little about the characteristics of this serological response. METHODS We conducted a cohort study using the clinical database from Zhongshan Hospital, Medical College of Xiamen. In total, 1,327 HIV-negative patients with primary, secondary, latent, and tertiary syphil...

Modern cancer treatments have substantially improved cure rates and have generated a great interest in and need for proper statistical tools to analyze survival data with non-negligible cure fractions. Data with cure fractions are often complicated by dependent censoring, and the analysis of this type of data typically involves untestable parametric assumptions on the dependence of the censorin...

With an ever broadening use of composite materials manufacturers are in high demand of 1 efficient curing cycles to reduce costs and speed up production cycles. One method to to archive this 2 goal is active cure monitoring to determine the exact time of curing needed. This article provides a 3 novel method to measure the cure inside of closed tools by using ultrasonic spectroscopy. For this a ...

The ability of naturally infected and cured mice to resist reinfection with tick-transmitted Borrelia burgdorferi was tested over a 1-year period. All of the mice were resistant to reinfection when they were challenged at 1.5 months after cure. The majority of animals were resistant to reinfection for up to 10.5 months after cure, but this resistance was lost at 1 year after cure. Both protecte...
