The present invention provides particulate flow enhancing additives for improving the flow properties of dry particulate cementitious materials. The ice cube-making machine has an evaporator package, a separate compressor package and a separate condenser package. , 1560 nm, to sample incoming optical pulses in approximately the same wavelength range. Events may be correlated with image as captured from internalexternal camera or nanny cam, for example to enable saving video of the event, such as the first steps of a child, violent shaking events, sporting, military or other motion events including concussions, or falling events associated with an elderly person. The unique identifier may correspond to the participant identified from the audio information. A second portion of the coil extends below a second surface of the magnetic core.
