A proposed method for estimating the electrical conductivity of cement paste pore solution at 25 °C is based on the concentrations of OR -, K + and Na + .The approach uses an equation that is a function of the solution ionic strength, and requires a single coefficient for each ionic species. To test the method, the conductivity of solutions containing mixtures of potassium hydroxide and sodium ...

The display of repertoires of human antibody (Ab) fragments on fila mentous phages and selection by binding of the phage to antigen (Ag) have provided a ready means of deriving human Ab against purified Ag. However, it has been more difficult to obtain phage Ab against an indi vidual Ag of a complex mixture, such as cell surface Ag. Using the technique of "guided selection," we generated human ...

Mobility is the cause for new requirements on database systems. Database systems used in classical LANor hostbased environments provide these new features deficiently. New concepts are needed in mobile environments. The conventional client-server architecture has to extended in a client-agent-server architecture. We describe new approaches in database technology to meet the new requirements lik...

The root of the word “meditation” is Latin “mediare,” meaning “to be in middle” or intercede” according to Dictionary.com. This exactly what Reina-Gutierrez et al describe a secondary analysis cluster randomized controlled trial (the MOVI-daFIT! Study), which sought assess effectiveness physical activity initiative improve cardiorespiratory fitness (CRF), executive function, and academic achiev...

Shadows, particularly soft shadows, play an important role in the visual perception of a scene by providing visual cues about the shape and position of objects. Several recent algorithms produce soft shadows at interactive rates, but they do not scale well with the number of polygons in the scene or only compute the outer penumbra. In this paper, we present a new algorithm for computing interac...
