Controls palette

Front panels are built by placing controls and indicators from the controls palette. The controls palette can be accessed using view menu bar in the front panel or performing a right-click on the mouse over an empty space in the front panel. Apart from controls and indicators, the controls palette provides a few objects or shapes for decorating the front panel. Figure 5.3 shows the control palette with Modem tab expanded. 

The front panel and block diagram objects that are required for the VI are chosen from the controls palette and the functions palette, respectively. Then the objects are dragged from their palettes and placed in their respective windows. Common operations such as cut, copy, paste, and delete are supported in Lab VIEW. The objects can be selected individually or as a group using the mouse pointer. 

In the front panel shown in Figure 5.20, add three numeric controls from the controls palette. Name the numeric controls with the following labels No of Samples, Sweep width min, and Sweep width max. ... 

Analytical scientists will provide support for many of the activities in a biopharmaceutical company. They are responsible for characterizing the molecules in development, establishing and performing assays that aid in optimization and reproducibility of the purification schemes, and optimizing conditions for fermentation or cell culture to include product yields. Some of the characterization techniques will eventually be used in quality control to establish purity, potency, and identity of the final formulation. The techniques described here should provide the beginning of a palette from which to develop analytical solutions. 

Open the reference molecule and color the whole molecule with reference color (shift-click the square box in the Control panel to open color palette, and select the desired color).

Both testing laboratories and accreditation bodies are looking for procedures and guidelines for planning and controlling the test method validation process. However, the discussion above has clearly indicated that one single procedure cannot be developed. Consequently, a palette of different choices of validation techniques has to be developed. How detailed the validation will be, depends on the circumstances (needs, costs, possibilities, risks, etc.). 

The 20 different amino acids in the linear polypeptide chain are the components that are arranged in a unique manner for each type of protein. If there are 200 or more amino acids, the number of different ways of linking these 20 amino acids, and hence of forming possible three-dimensional structures, is 200 . This means that this simple palette of amino acids leads to many possibilities for diversity in the protein itself, and that an almost infinite number of protein structures can be designed. I will describe in this chapter an example of how the long polypeptide chain of a protein consisting of many hundreds of amino acids folds in a totally unique manner to give a supermolecule with distinctive and well-controlled properties. 

Nature designs thousands of enzymes in the manner described here for D-xylose isomerase. Account is taken of the overall thermal stability, of carefully controlled substrate binding and the elimination of product, of protection from other enzymes, of the correct solubility and of placement in the organism in vivo. All of these requirements, and many not fisted here, are met. The palette is merely the 20 amino acids, but a wide range of electrostatic, hydrophilic or hydrophobic, space-filling and organizational considerations have been necessary for the final arrangement. The end product is unique and a marvel. 

Transportation of pasted plates in the tunnel dryer results not only in removal of excess moisture from the paste, but also in drying the plate surfaces. Thus sticking of plates to one another is avoided when they are arranged in piles (stacked). At the outlet of the tunnel dryer the plates have a temperature of 40—45 °C and moisture content 9.5%. They are then piled (stacked) on palettes to be transported to and loaded into the curing chamber. The controlled parameters of the plates after drying are plate weight, moisture content of the paste and paste density. 

In the present version 7.3, all the elements can be shown on a palette at the base of the window as shown in Figure 7.9b by chcking View at the top of the window and chcking the box next to Model Libraries. Elements can be easily dropped onto the PFD. Control signals can be added by clicking the box on the left side.
