Improving Your Surface

Part IV Taking the Shape of Geometric Word Problems

Non-polar, high-molecular-weight compounds or matrix components are often annoying. They will stick onto rough, dirty surfaces. This tells you indirectly what to do. To avoid memory effects, improve your sample preparation and make sure your equipment is clean. 

With product-prediction problems, there will always be some doubt as to whether you are at the lowest accessible point on the surface or are in the energy well of a side product. Hopefully, the end should be obvious because you will definitely be downhill from your starting point, and it will seem that all alternatives for several steps around are definitely uphill. Again, knowing when you are done also improves with practice. 

Safety culture surveys can surface challenges and barriers to EHS excellence. They can show how inherent cultural weaknesses impact morale, productivity and quality. Safety culture surveys qualify what s going on and quantify key dimensions — assigning data-oriented results to particular issues and concerns. This can serve as your baseline for ongoing improvement and alignment with corporate values. 

You may have historic plaster walls in your house, or you might have faux-finish plaster meant to replicate the feel of these walls. Whatever the case, it s useful to know how to repair it. The techniques in this section apply to stucco (usually an exterior finish) as well as to lime plaster (calcium hydroxide mixed with sand and water), though you ll need to add Portland cement to the mix for exterior stucco surfaces (the experts at your local home improvement store should be able to help). 

One possible automotive improvement would be a radiator based on hollow fibers. Such a device offers a huge surface area per volume, and hence a smaller, lighter radiator for the same job. However, because of the small diameter of the hollow fibers, coolant flow will be laminar. Use your knowledge of interfacial transport to suggest appropriate correlations for the overall heat transfer coefficient in such a device.
