The purpose of this study was to test the compressive strength of white mineral trioxide aggregate (WMTA) and gray mineral trioxide aggregate (GMTA) when mixed with sterile water or local anesthetic… Expand
Electrochemical disinfection, an environmentally acceptable method of drinking water disinfection?
In general, chlorination is the method of drinking water disinfection most favoured by the water industry. Occasional outbreaks of water transmitted disease, the identification of chlorine as a… Expand

A series of experiments to determine the survival characteristics of environmental and faecal coliforms in a 1·3 km long experimental pipe distribution system is described. In the first experiments,… Expand
The fate of Escherichia coli through water treatment and in distribution
The removal of E. coli bacteria at each stage of water treatment is presented, showing how the filtration stages contribute most to reduction of bacterial numbers in the water. At treatment works… Expand
Bacterial degradation of lignified wood cell walls in aerobic aquatic habitats: decay patterns and mechanism proposed to account for their formation
- D. M. Holt
Etude de la degradation bacterienne des parois cellulaires d'echantillons de Fagus sylvatica et Pinus sylvestris immerges dans de l'eau douce ou de l'eau de mer. Presentation des resultats obtenus… Expand
Bacterial degradation of lignified wood cell walls in anaerobic aquatic habitats.
Test blocks of beech (Fagus sylvatica) and Scots pine (Pinus sylvestris) were buried in fresh, brackish, and seawater anaerobic muds for periods ranging between 1 and 18 months. At appropriate time… Expand
Microbial decay of lignocellulose in the marine environment
Microprocessor‐controlled time domain reflectometer for dynamic shock position measurements
Time‐domain reflectometry is used in a novel way to dynamically measure shock propagation in various media. The primary component in this measurement system is a digital time domain reflectometer,… Expand
