While fluorochemicals have been detected all over the world and in wastewater
treatment plants, the effect of wastewater effluent on the receiving waters has not been
evaluated. In the first study, the mass flow of fluorochemicals emanating from
wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...
It is well established that the extended range V(I) transition behavior in
filamentary superconducting composites depends strongly on the processing
conditions of the composite. Based on previous work, a model proposed by
Warnes et al predicts that the second derivative of the V(I) transition is related to
a more fundamental...
The mechanical performance of composite materials is determined by the mechanical properties of their individual components and the effective load transfer between these components. Binders are commonly used to bond composite components together and to provide effective load transfer between them. In wood-based composites the binder-component load transfer occurs at...
OBJECTIVES. Bioactive glass (BAG) is known to possess antimicrobial properties and release ions needed for remineralization of tooth tissue, and therefore may be a strategic additive for dental restorative materials. The objective of this study was to develop BAG containing dental restorative composites with adequate mechanical properties comparable to successful...
Timber-concrete composite (TCC) floors have improved strength and stiffness when compared to timber-only floors, allowing for longer spans in buildings and improved life safety. However, North America does not have codes and standards that recognize TCC floors, particularly the improved life safety performance of these floors in fire. Therefore, alternate...
To better understand the suitability of balsa wood as a core material for sandwich
composites, this paper presents a detailed study of the fracture properties of balsa. The
experiments looked at mode I, mode II, and mixed-mode fracture with crack growth both parallel
and perpendicular to the wood grain direction....
A computer program called SAPWOOD which possesses the
capability of performing linear or nonlinear, static or
dynamic response including seismic excitation for wood-framed
buildings with semirigid connection systems is
presented in this study. Program SAPWOOD is a modification
of the program NONSAP by adding new elements such as a
linkage...
