Some of the Other Tools

If you have the facility to acquire good quality spectra of the types discussed in this chapter and the one preceding it, then you should be well positioned to tackle virtually any problem that comes your way. We have covered what in our view are the most important and relevant techniques - but there are many others you may have heard of, all with their own enticing sounding acronyms. We ll now take a look at some of them and try to outline some of their potential uses as well as their shortcomings.

Oxidation numbers are tools that scientists use in written chemical equations to help them keep track of the movement of electrons in a redox reaction. Like some of the other tools you have learned about in chemistry, oxidation numbers have a specific notation. Oxidation numbers are written with the positive or negative sign before the number (+3, +2), whereas ionic charge is written with the sign after the number (3 +, 2+).

Change analysis is one of the techniques associated with the Department of Energy s management oversight and risk tree (MORT) approach to system safety. Unlike the MORT chart itself or some of the other tools and techniques associated with the MORT program, change analysis is a very simple, straightforward process that is relatively quick and easy to learn and to apply. 

Code analysis Code analysis goes into the very heart of the software system and verifies that the coded program actually accomplishes what it is designed to do. Software fault trees and Petri-Nets are used, as well as various other techniques. Some of the other tools used are code logic analysis, code data analysis, code interface analysis, measurement of complexity, code constraint analysis, safe subsets of programming languages, and formal methods and safety-critical considerations. 

To learn more about the requirements and how to obtain copies of the pamphlet contact the National Lead Information Center at 1-800-424-LEAD (5323) or visit EPA s website at www.epa.gov/lead. Some of the other tools you need are listed in Box 3.1. Personal protective equipment needed is shown in Box 3.2. 

Some of the other features of this program are the ability to compute transition states, coordinate driving, conformation searches, combinatorial tools, and built-in visualization. The builder includes atoms and fragments for organics, inorganics, peptides, nucleotides, chelates, high-coordination geometries, and... 

You ve probably already heard a lot about your general chemistry course. Many think it is more difficult than other courses. There may be some justification for that opinion. Besides having its very own specialized vocabulary, chemistry is a quantitative science, which means that you need mathematics as a tool to help you understand the concepts. As a result, you will probably receive a lot of advice from your instructor, teaching assistant, and fellow students about how to study chemistry. We hesitate to add our advice experience as teachers and parents has taught us that students do surprisingly well without it We would, however, like to acquaint you with some of the learning tools in this text. They are described in the pages that follow. 

It is now possible to model the wafer-level performance for most CMP processes. These models cover only some of the important tool or process design issues, such as relative velocities and pressure dependencies additional work is needed to predict the results for other parameters such as slurry composition or particle size, temperature dependencies, pad properties, and other effects. Die-level modeling has been used effectively to identify... 

Some of the hand tools used by carpenters and other workers, including firefighters, are listed in the table on pages 196-197, along with their most common uses and some examples of each kind. 

When processing plastics some type of tooling is usually required. Tools include molds, dies, mandrels, jigs, fixtures, punch dies, perforated forms, etc. The terms for tools are virtually synonymous in the sense that they have some type of female and/or negative cavity into or through which a molten plastic moves usually under heat and pressure or they are used in secondary operations such as cutting dies, stamping sheet dies, etc. These tools fabricate or shape products. In this chapter injection molds and extrusion dies are primarily reviewed because they represent over 95% of all tools made for the plastic industry. This chapter also includes information applicable to other molds and dies used in the other processes some of the other chapters too provide information applicable to their tools. 

In this section, we briefly review some of the available tools, their features, and possible pedagogical uses. Other tools not necessarily related to Galactic chemical evolution are also available, and the interested reader is invited to explore them at webnucleo.org. 

Spark source mass spectrometry (SSMS)i was (irsi introduced in the I930s as a general tool for multielement and i.sotope trace analyses. Ii was n(ti until lO.sS. however, that the first commercial spark source atomic mass spectrometer appeared on the market. After a period of rapid development in the 1960s. the use of this technique leveled off and then declined with the appearance of ICPMS and some of the other mass specironietric methods discussed in this chapter. C ur-remly, SSMS is still applied to samples that are not easily dissolved and analyzed by ICP. 

Once the CED is created, the team actively gathers data to investigate each of the causes. The team then analyzes this data to determine what the primary causes of the problem are. Remember that the CED was created to identify all possible causes and it typically includes many items that may not be contributing to the problem so once it is created the actual cause must be separated out from those on the list. To do this, some of the other 7 Quality Control Tools can be used to help analyze the CED. 

The findings show that in general most managers had a positive view about the impact of strategic tools and techniques, both at the firm (0.63) and the function level (0.69). Indeed, unlike managers in some of the other functional areas analysed here, there were no negative scores in the strategy... 

A plethora of safety analysis techniques are available to the practicing engineer, some of them are very complex and involved, and some are quite simple. They are applied at different phases of the system life cycle. Some of the safety tools are quantitative and some are not. All of the safety analysis techniques do have some sort of cost attached to them some are very expensive and others are not as costly. After reading about the different safety techniques described here, you are probably somewhat overwhelmed with trying to decide which one to use. This section will help you to decide. 

Although no technologist would want to use Raman s instrumentation today, it is nevertheless important to realize that the foundation of Raman spectroscopy was created with his early tools. Therefore, the following few lines will help with the understanding of the remainder of this and of some of the other chapters of this volume. 

This chapter discusses some of the common tools financial experts and others use to make supply chain and operations decisions. The tools help inform decisions as well as communicate how the company is affected financially. After reading this chapter, you will be able to apply the tools and communicate more clearly.
