Since dental floss is able to remove some inter-proximal plaque, frequent regular dental flossing will reduce inter-proximal caries and periodontal disease risks. [ 1 ] [ 3 ] Results of a high level of evidence meta-analysis recently found that floss may not be the most effective method for interdental cleaning, contrary to common belief at the ...
The National Institute of Dental and Craniofacial Research carried out further research into dental care for minorities and found that black and Hispanic families in lower-income areas had much higher incidences of tooth decay. [12] Similar research shows that poor dental hygiene directly affects educational abilities and school attendance. [13]

An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero." [2]
Many of the measurement and control unit manufacturers signed up to the Fieldbus consortium but rather than one standard emerging each manufacturer promoted their own 'standard' leading to a myriad, and confusing, range of physical and logical systems. Modern process control networks rely on Ethernet, TCP/IP, and Microsoft Windows technology. [1]
A networked control system (NCS) is a control system wherein the control loops are closed through a communication network.The defining feature of an NCS is that control and feedback signals are exchanged among the system's components in the form of information packages through a network.
