A method and apparatus for measuring the quality of live, standing timber employs deep-set spike probes angled to create a longitudinal compression wave. Alignment tools and isolation of the probes provide an improved signal, automated detection of probe separation and amplitude-independent pulse discrimination process ensure higher reliability and repeatability of the measurements, and wireless operation provides operational efficiencies.

The present invention relates to oral compositions for treating sensitive teeth.These compositions comprise an agent for desensitizing sensitive teeth, such as potassium nitrate of strontium acetate, and a particulate abrasive material which is hydroxyapatite. The hydroxyapatite is compatible with the desensitizing agent.

A monitoring system for monitoring fluid used in an environment such as a trade/industrial waste plant or air conditioning cooling tower installation is disclosed. The system includes sensors (26 to 34, 53 to 55) for sensing parameters of the fluid, a remote monitoring system (40) for receiving signals indicative of the measured parameters from the sensors and for applying rules to the signals to determine whether the signals meet predetermined criteria so that an event indication can be generated if the predetermined criteria are not met. The system (40) includes a processor (41) and a memory (42). The system (40) is connected to a central station (72) by a communication link (74). The central station (72) includes a server (80) and data store (82) which are connected to the Internet so the data can be interrogated by a user via a PC (86). The system also generates an audible or visual alarm (62) or forwards a message to authorised personnel via SMS message to a mobile telephone (87) or by e-mail in the case of an event condition being generated. A user is able to log onto the system and interrogate data retained in the system relating to the user's sites to determine the operating parameters of the system and also to determine problems if an event indication is established.

摘要:
The invention relates to oral compositions for combating dental caries. The compositions comprise a fluorine-containing anti-caries agent such as sodium fluoride or sodium monofluorophosphate and a particulate hydroxyapatite as abrasive. These ingredients are surprisingly compatible in that there is a reduced loss of available fluoride upon storage.
