The system has been implemented as a three-tier architecture by separating its functions into three separate layers.
The medial thigh usually has a relatively thin dermal compartment separated by lamina profunda strati subcutanei from two separate layers of adipose tissue.
Over the past few years, the team has uncovered fragments from an estimated 25 ostrich eggs in 18 archaeological layers dated by two separate techniques to between 55,000 and 65,000 years ago.
To reproduce colour by subtractive three-colour synthesis (Figure 6), colour films first break down the colours of an image into their primary components by means of three separate sensitized layers, each of which responds exclusively to blue, green, or red light.
Uncontrolled water input was avoided by installing the system under a light-transmissive roof and the evaporation was minimised by covering the soil with two separate geotextile layers.
The A-scans in each image were averaged together for quantitative assessment of resolution via the intensity peaks generated by two bright layers separated by a dark layer.
Mediterranean hydrodynamics are driven by three layers of water masses: a surface layer, an intermediate layer, and a deep layer that sinks to the bottom; a separate bottom layer is absent.
"The buildings are owned by second- and third-generation layers of three separate families whose patriarchs accumulated exactly this type of real estate," he said in an e-mail: "low maintenance, high trafficked retail rentals.
In rodents, maternal blood and fetal blood vessels are primarily separated by two syncytiotrophoblast layers, but in humans, only a syncytiotrophoblast monolayer separates fetal blood vessels from maternal blood (Malassiné et al. 2003).
Square holes have been cut into the dock, like sample pools, framed by three layers of screens, each separated by inflatable bike-tire tubing.
