Lego® bricks

The bottom up approach ensures the quality of the end result by building up from the foundations rather like a Lego model. In testing terms this is illustrated in Figure 7. These Lego bricks are equivalent to the individual modules in any measurement system. Each brick is qualified or confirmed as suitable for use before the next layer is built. In this way, integrity is assured all the way to the...

In this simple model a crucial point is however missing, since the LEGO bricks have no mutual interaction, which may influence their distribution on the base plate. Such mutual interactions are, however, common for adsorbed entities on surfaces and can influence their special arrangement as has been shown, for example, in the case of PTCDA on the Ag surfaces in Fig. 2. To avoid that the lateral interaction of the deposited entities plays the decisive role for the structure formation in a template-controlled process and in order to ensure that the growth is solely controlled by the template the active sites of the template have to be sufficiently far apart from each other or provide a much stronger interaction than the intermolecular interaction. In general this condition requires the active sites to be separated by at least a few atomic distances (> 1 nm). 

Major applications Computer cases, telephones, casings for domestic electrical equipment, safety helmets, plastic baths and shower trays. Lego bricks. 

Sectional-Modular Architecture All interfaces in a sectional-modular architecture are the same. However, a common bus is not provided in a product with sectional-modular architecture. For example, LEGO bricks are components with the same interfaces so that they can be connected with each other. 

The Mega Bloks company used a process called reverse engineering to design its interlocking blocks so they would be compatible with Lego bricks. is the process of measuring and analyzing... 

Lego bricks can be used to illustrate the effect of changing surface area on reaction rate (Figure 5.12). Build about 16 bricks into a cubic-shaped (or cuboid-shaped) block. Measure the exposed surface area by counting the number of brick faces visible externally. Then divide the large block into four smaller ones. Recount the number of brick faces visible. Finally separate out each individual brick - how many faces are visible now ... 

Tomoe et aL designed a small synthetic highly active promoter using a LEGO brick principle (Fig. 9.1). The spacer sequence of the JeT promoter was randomized to create an SPL which was tested with the reporter genes EGFP (Enhanced GFP)... 

Three key parameters control the interaction of a given lipid with its neighbors in a supramolecular assembly of lipids in water (1) the melting temperature, which determines in which physical state (solid or liquid) is the lipid at physiological temperature (2) the global shape of the lipid, here viewed as a LEGO brick, which determines what kind of architecture...

Some typical examples of amorphous thermoplastics are acrylonitrile-butadiene-styrene (ABS), polymethylmethacrylate (PMMA), polystyrene (PS) and polycarbonate (PC). Applications for amorphous thermoplastics vary from car bumpers to Lego bricks, and from motorcycle helmets to ski boots.
