Lock cells

The locked cells in any worksheet could not be opened or altered by laboratory staff without the knowledge and agreement of the Study Director. Use of the locking function in the workbook, therefore, constrained the analytical laboratories to a single system for recording data and calculating results. 

Although SC appears as loosely separated layers in micrographs (Figure 5), this appearance is false. It results from loss of intercellular cement during preparation for sectioning (2). However, such views do show some of the interdigitations that cooperate with desmosomes to lock cells together (44). The intercellular cement probably fills all space between these mechanical junctions in SC (32). 

You can protect either a whole workbook or a worksheet within a workbook. Within a worksheet, you can lock cells so that they cannot be changed, and you can hide cells so that the user can t view the cell contents.

Grinding. The final step in chocolate Hquor production is the grinding of the kernel or nib of the cocoa bean. The nib is a cellular mass containing about 50 to 56% cocoa fat (cocoa butter). Grinding Hberates the fat locked within the cell wall while producing temperatures as high as 110°C.

More complex models must carefully consider additional factors such as the receptor structure of helper T cells and allow for, what in reality, is a less than perfect lock and key match between antibody and antigen. For the latter case, Stauffer [staufF92] describes two schemes in which more than one type of antibody fits a given antigen and more than one type of antigen corresponds to a given antibody. 

Time-resolved microwave conductivity measurements with electrodes in electrochemical cells can conveniently be made with pulsed lasers (e.g., an Nd-YAG laser) using either normal or frequency-doubled radiation. Instead of a lock-in amplifier, a transient recorder is used to detect the pulse-induced microwave reflection. While transient microwave experiments with semiconducting crystals or powders have been performed... 

Living cells contain thousands of different kinds of catalysts, each of which is necessary to life. Many of these catalysts are proteins called enzymes, large molecules with a slotlike active site, where reaction takes place (Fig. 13.39). The substrate, the molecule on which the enzyme acts, fits into the slot as a key fits into a lock (Fig. 13.40). However, unlike an ordinary lock, a protein molecule distorts slightly as the substrate molecule approaches, and its ability to undergo the correct distortion also determines whether the key will fit. This refinement of the original lock-and-key model is known as the induced-fit mechanism of enzyme action. 

Figure 4. The Brownian ratchet model of lamellar protrusion (Peskin et al., 1993). According to this hypothesis, the distance between the plasma membrane (PM) and the filament end fluctuates randomly. At a point in time when the PM is most distant from the filament end, a new monomer is able to add on. Consequently, the PM is no longer able to return to its former position since the filament is now longer. The filament cannot be pushed backwards by the returning PM as it is locked into the mass of the cell cortex by actin binding proteins. In this way, the PM is permitted to diffuse only in an outward direction. The maximum force which a single filament can exert (the stalling force) is related to the thermal energy of the actin monomer by kinetic theory according to the following equation ...

Determination of the effective transport coefficients, i.e., dispersion coefficient and electrophoretic mobility, as functions of the geometry of the unit cell requires an analogous averaging of the species continuity equation. Locke [215] showed that for this case the closure problem is given by the following local problems ... 

By using a multichamber system [129], exchange of residual gases between successive depositions will be strongly decreased, and very sharp interfaces can be made. Furthermore, the use of a load-lock system ensures high quality of the background vacuum, and thus low levels of contaminants in the bulk layers. Multichamber reactor systems have been used for the fabrication of solar cells, and considerable improvements in energy conversion efficiency have been achieved [130, 131].
