INPUT ARTICLE: Article: Canned vegetables are generally high in sodium. To cut the salt from these, buy canned vegetables that say "no salt added" on the label. That ensures you are getting the vegetable without added salt. If you want a little bit of salt to taste, you can add a small amount of salt when you put the food on the plate. Consider cooking your vegetables with spices and herbs to eliminate the need for added salt. For example, try adding rosemary and thyme to green beans or ginger and sage to carrots. Many sauces, such as pasta sauces, have a lot of added sodium. Most brands offer a sodium free option. If you can't find sodium free, you may find a reduced sodium option. Make sure to check the serving size. Reduced sodium varieties may not be low in sodium if the serving size is smaller than what you would eat. Canned beans are full of unnecessary salt. However, beans are a really healthy food. To get away from this, try dried beans. This will give you the benefits without added sodium. Dried beans take longer to cook, so cook enough for multiple servings for the week. Many grain items may be full of sodium and other unhealthy additives, especially if you buy flavored varieties. Replace these sodium-heavy versions with plain, whole grains that are relatively salt free. For example, instant oatmeal not only contains added sodium, but sugar as well. Plain, steel cut oats are a healthier option. When buying cereal, look for brands that have whole grains as the first ingredient. Make sure to buy a brand with a low sodium content. Try whole grain pasta, brown rice, quinoa, buckwheat, and bulgur. Condiments are pantry staples, but they can be loaded with salt. Read the labels carefully and compare brands and types before buying. If available, get a reduced sodium, low-sodium, or no-sodium added variety. Condiments may include ketchup, mustard, dressing, olives, pickles, relish, dips, and soy sauce. Consider leaving the condiments off your food completely.

SUMMARY: Look for "no salt added" canned vegetables. Buy sodium-free sauces. Choose dry beans. Buy whole grains. Use caution with condiments.

In one sentence, describe what the following article is about: Fortunately, Mac owners have a plethora of options available to them for doing this. Choose whichever method suits you the best. Remember that virtual storage and physical storage each have advantages and disadvantages, and remember that anything you don't back up will be gone forever once you reformat your computer's hard drive. Be thorough. Back up with iCloud if most or all of your content is legally purchased files from the iTunes store. The iCloud service backs up all such content automatically on a daily basis, as well as details like user settings, text messages, phone contacts, and so on. For most users, iCloud is more of a smartphone option than a computer option. Back up to an external hard drive. This is the time-honored method most people use to back up their computer. Run a program such as Apple's own Time Machine utility, and point it to the external drive you have connected to your computer. The program will create a backup copy of everything except system files. You can also back your drive up manually by literally dragging everything you want to save onto your external hard drive's desktop icon en masse, but this is messy, slow, and less reliable than letting a program take care of it for you, in most cases. Back up to physical media. When all else fails, if your computer has a writable optical drive (such as a DVD/RW drive), you can purchase a stack of blank discs and manually back up content to the discs, one disc at a time. This isn't recommended, as it's easy to misplace or damage the discs, but in a dire emergency it can help you save data and applications that might otherwise have been lost. Load your Mac's Install disc into the optical drive and reset the computer. As the computer boots up again, hold down the "c" key to force it to boot up from the Install disc. You'll see a list of language options, and then a menu screen. From this point until you've completely finished reinstalling your system software and reset the computer, do not remove the Install disc from the drive for any reason. Select "Utilities" from the menu, and "Disk Utility" from there. In Disk Utility, choose the hard disk you want to erase from the drop down menu and click the "Erase" tab, then click and confirm the "Erase" button. Disk Utility will erase that entire drive. Erasing a hard drive takes time. Be prepared to wait a while and, as before, don't jostle or move the computer while it's erasing. Be very careful not to select your backup drive by accident. If you're worried you might, just unhook it from your computer before you restart it. Once you're done erasing your hard disk, quit Disk Application to find a Mac Installer window. Click the "Continue" button to view the license agreement. Read it if you want, then accept it and click the hard drive you just erased on the next screen. Click "Install" to install the system software. Once you've finished installing the system software, click "Restart" to restart your Mac and boot up as normal. Your Mac will guide you through initial setup; once you've finished, it's time to update to the latest version of the OS you were using. Visit your account at Apple.com and download and install all the updates you previously purchased. Depending on the method you chose, either load your optical discs sequentially, drag files from your external hard drive, or run Time Machine (or another backup utility) and choose to restore your old files from an external hard drive. All three methods take time, so be patient. If you have data backed up on iCloud, you can simply log in and copy it back to your hard disk.
Summary: Back up files. Restart from disc. Run Disk Utility. Reinstall the system software. Restart and update. Restore your files.

Enjoy yourself at the pool party, but remember to take special care of your skin. Bring your sunscreen with you and reapply as necessary. Remember, sunscreen doesn't prevent you from tanning, it just shields you from harmful, cancer-causing UV rays. If you're planning to swim, make sure that your sunscreen is waterproof You need to reapply your sunscreen at least every two hours. Make sure that your sunscreen isn't expired. You'll be in the sun, and possibly the water, all day and you want your hair to look great all day (and night). Braids, buns, and ponytails are the perfect look for any pool party, are low maintenance, are easy to fix throughout the day, and will give your hair added waves when you take it down. You might also go for the windblown look, which should last all day if you put just a bit of mousse in your hair while it's wet. Get summery beach hair by encouraging natural waves. Take a shower, put in some hair gel or hair spray, and scrunch your hair. If you choose to wear makeup, it needs to be as subtle and natural looking as possible. Only use waterproof makeup, and use it sparingly. The best makeup that you can wear for fashion at a pool party is a good, waterproof mascara. This will open up your eyes and subtly draw attention to them. There's also other waterproof makeup, like eyeshadow, eyeliner, brow gel, and concealer.

INPUT ARTICLE: Article: Apply a known force to the material in both the stress and strain directions. Measure the dilation (dSs) that occurs in the material when stress only is applied. Measure the dilation (dSn) that occurs in the material when the external force applies only strain.

SUMMARY:
Measure the proportional fractional volume change (also known as dilation) of the material.
