摘要:
The present invention relates to oral care compositions, especially toothpastes, comprising: a safe and effective amount of phosphopeptide-amorphous calcium phosphate complex (“PP-ACP”); a safe and effective amount of a fluoride ion source; a pharmaceutically-acceptable topical, oral carrier, and a safe and effective amount of a calcium chelator, wherein the composition has improved fluoride stability. This invention further relates to a method of maintaining the fluoride levels in an oral care composition comprising a safe and effective amount of PP-ACP, a safe and effective amount of a fluoride ion source, and a pharmaceutically-acceptable topical, oral carrier, by adding, to the composition, a safe and effective amount of a calcium chelator.
摘要:
A flow control center can include a barometric sensor, at least one ball valve assembly, and a computing device. The ball valve can be controllable among a plurality of discreet positions to selectively change a flow of fluid. The computing device can have a communication device configured to receive signals from the barometric sensor. The computing device can determine a first flow rate in response to the sensed pressure represented by the first signal. The computing device can also control a motor of the ball valve assembly to move a ball valve to a first of the plurality of discreet angular positions. The first of the plurality of discreet angular positions can correspond to the sensed pressure represented by the first signal.
摘要:
The application discloses a unique technique for watering a garden. This technique involves application of a watering system. This system provides an enclosure about the garden plot that includes a barrier permissive of light and air to the garden plot and at least partly preventing entry of land animals of interest to the garden plot. The garden plot is watered through a number of misting nozzles connected to the enclosure and held above the garden plot. Water is distributed to the misting nozzles with a conduit loop. Multiple conduit loops may be included to disburse the water.
