It is good practice to save your file at each stage by selecting the Save option under the File menu. Note that, if you need to go back to a previous version, then you will need to reimpose any constraints you have been using as these are not saved. Thus, in this case you would need to select the cobalt atom and Constrain Geometry to Octahedral under the Build menu. 

Another way to determine a computer s CPU is to save your work, exit any open programs, and restart the computer. Watch closely as the computer returns to its normal state. You should see a notation that tells you what chip you are using. If you are using MS-DOS, you can also run Microsoft Diagnostics to view the processor type (that is, unless your computer has a Pentium, in which case it will report a very fast 486). 

If you are handwriting your first drafts, always write on one side of your paper only, in case you want to cut and tape together portions of drafts or you want to experiment with interchanging parts of a particular draft. (If you have written on both sides, you may have to recopy the parts of your essay you want to save your time is better spent creating and revising.)... 

Heavy objects on construction sites are usually lifted by forklifts, hoists, cranes, and other types of materials-handling equipment. However, it s often necessary to load or unload moderate to heavy objects by hand. When that is the case, knowing the proper ways to lift can save your employees pain and misery. 

When you borrow money, you pay additional funds for the service. When you deposit money into savings you earn additional funds for your deposit. In either case, the additional funds are called interest. The money borrowed or deposited is called principal the percentage used to calculate the additional funds is called the interest rate. Interest earned or owed is dependent not only on the principal and rate, but also on another variable, which is the length of time in years. To calculate interest for one year, you can set up a proportion. Because interest is such a common occurrence in the business world, there is a formula used to calculate interest / = PRT. The interest is I, P is the principal, R is the rate written as a decimal, and T is the time in years. 

Whatever style of notebook is used, the principle is the same Record all data directly in your notebook. Data may be copied into tlie notebook from a partner s notebook in those cases where it is clearly impossible for both partners to record data at the same time. Even then, a carbon copy or a photocopy of the original pages is better, since it avoids copying errors and saves time. In particular, do not use odd scraps of paper to record such incidental data as weights, barometer readings, and temperatures with the idea of copying them into the notebook at a later time. If anything must be copied from another source (calibration chart, reference book, etc.), identify it with an appropriate reference. 

Protect your household s financial well-being before a disaster strikes—review life insurance policies and consider saving money in an emergency savings account that could be used in any crisis. It is advisable to keep a small amount of cash or traveler s checks at home in a safe place where you can quickly gain access to it in case of an evacuation. 

We must emphasize, however, that many of the unit operations encountered in the analytical laboratory are timeless. These tried and true operations have gradually evolved over the past two centuries. From time to time, the directions given in this chapter may seem somewhat didactic. Although we attempt to explain why unit operations are carried out in the way that we describe, you may be tempted to modify a procedure or skip a step here or there to save time and effort. We must caution you against modifying techniques and procedures unless you have discussed your proposed modification with your instructor and have considered its consequences carefully. Such modifications may cause unanticipated results, including unacceptable levels of accuracy or precision in a worst-case scenario, a serious accident could result. Today, the time required to prepare a carefully standardized solution of sodium hydroxide is about the same as it was 100 years ago. 

In many cases, other poster sessions follow yours or other activities are planned for the poster room, so it is essential (and prudent, if you don t want to lose the poster ) to take it down promptly at the designated time. At ACS national meetings, it should be removed immediately after the close of the session. Used posters are nice to save for display at the home institution—outside your office or lab, for example, to inform (impress) visitors, colleagues, and future co-workers about your productivity and accomplishments. 

Z xf. Fortunately, many of the new hand calculators have a linear regression program built into them that calculates a and b from Eqs. (AL9) and (ALIO) if we simply key in the data properly. Some calculators do not have the linear regression program instead they have a statistical function that calculates these sums and stores them in accessible registers. In this case the sums can be recalled from the registers and used in Eqs. (AI.9) and (ALIO) to calculate a and b. (A lot of time can be saved by reading the instruction booklet for your calculator )...
