Jigsaws, working with

Inlay. A router, some wood veneer, and a little artistic moxie can turn a table into a treasure. Draw the shapes of your inlay on carbon tracing paper, then onto thin wood veneer. Once the inlays are on the veneer, carefully cut them out with a sharp, fine-toothed jigsaw. Working with one piece at a time, use double-sided tape to hold the inlays on the table-top and trace deep lines around them with a utility knife. Remove the taped inlays and switch to your router. Use a Vie" bit set to the depth of your wood veneer to carefully rout your shapes into the wood. Glue the inlays in place and clamp until dry. Sand the tabletop smooth. End with a protective finish. 

Traditionally, the principal tools for the study of vanadate speciation in aqueous solution were UV/vis and electrochemistry. Unfortunately, the complex chemistry associated with vanadate has rendered much, but certainly not all, of the earlier work obsolete. The reaction solutions often contained numerous products that, a priori, could not be specified. Properly describing the chemistry was somewhat like doing a jigsaw puzzle without knowing what the pieces looked like or how many there were. Only with the advent of 51V NMR spectroscopy in high field NMR spectrometers was there a tool in place that allowed a coherent picture of V(V) chemistry to be fully developed. The combination of potentiometry with NMR spectroscopy has proven a certain winner. Additionally, x-ray diffraction studies have provided an invaluable source of information, but it is information that, in all cases, must be used with extreme caution when attempting to describe the chemistry in solution. 

Although EDRF/NO is relatively new in the world of pharmacology, its impact has been enormous. In just twenty-five years, more than 31,000 papers have been published with NO in the title and more than 65,000 refer to it in some way. That represents a lot of work, pieces of the jigsaw puzzle put together in laboratories, clinics, and medical centers globally ... 

When you begin a study of chemistry, you start to work on a challenging puzzle—the puzzle of matter. Every chunk of matter is a puzzle piece. Your puzzle box is the universe, and the box contains many different kinds of pieces. Your job, like that of the puzzle solver at the top of the page, is to figure out how to connect all the different pieces. Keep in mind that, as with an ordinary jigsaw puzzle, your goal is not only to connect the pieces but also to see the complete picture that emerges. 

Parallel to the experimental work, for example, testing an absorber (Figure 4-8), thermodynamic simulation calculations are carried out for the unit concerned. If the absorber can be simulated with the available material data in a calculation run in parallel, work on this step will be complete. The unit is then another piece which can be fitted into the jigsaw puzzle of the entire process, which is the next item which must be considered in an integrated trial plant. 

The projects were prepared in groups of four students with specific individual functions in each work and mandatory rotations. The four roles performed by each one were laboratory/informatics technician, analyst, reporter and coordinator. This way, all students performed the four established functions (a different one in each project), representing the corresponding role-jigsaw project system.
