In this paper, we describe the monitoring of Portand cement paste, with a 0.50 water cement ratio (w/c), during early age period, recurring to optical and electrical techniques. The optical monitoring of the cement paste was realized with FBG temperature sensors, and the temperature variations during the early age period were characterized. The RF values of the cement paste and therefore predic...

This literature review focuses on factors influencing drying shrinkage of concrete. Although the factors are normally interrelated, they can be categorized into three groups: paste quantity, paste quality, and other factors.

Caries are the localized destruction of the tissue s of the tooth by bacterial action; either enamel or cementum is demineralized by microbial acids. Traditionally the stem bark of Azadirachta indica was used to clean the teeth due to its antibacterial activity which reduced the incidence of dental caries. In modern life style, the use of Azadirachta indica was minimized and the incidence of de...

The aim of this in vitro study was to compare the remineralization potential of dental products containing calcium on human enamel softened by soft drinks. Fifty sound human premolar teeth were randomly divided into 5 treatment groups (n=10): artificial saliva, 1,000 ppm fluoride toothpaste, CPP-ACP paste, CPP-ACP with 900 ppm fluoride paste and tricalcium phosphate with 950 ppm fluoride paste....

BACKGROUND It is important for Dental Professionals to consider the evidence for the effectiveness of the preventive strategies used to maintain good oral health and reduce the risk of caries in their patients. Whilst many of the traditional preventive activities, including the recommendation and use of fluoride products and the placement of fissure sealants have a wealth of clinical evidence t...

In this paper, an evaluation is presented of a framework that supports flexible content repurposing. Unlike the usual practice where content components, such as slides, images, definitions, text fragments, tables, or diagrams, are assembled manually through copy and paste, the framework enables on-the-fly access and repurposing. Retrieval of relevant components is enabled by automatic decomposi...
