Problem: Write an article based on this summary: Check for a webcam. Install Skype. Follow installer instructions. Open Skype. Click on a contact. Start a video call. End the call when done.

Answer: Be sure your computer has a webcam. On most laptops, the webcam will look like a small hole in the top border of the screen. The majority of laptops made in the past five years have webcams. If you do not see a webcam, you will have to purchase an external webcam. Either go to your local computer store or purchase one online. You do not need to buy an expensive one, but if you plan to make a large amount of video calls, you may as well purchase one that will provide for high-quality videos. Depending on whether or not you have a Mac or a PC, the download link is different. For Windows users: Go to this link: http://www.skype.com/en/download-skype/skype-for-computer/. Click on the green button that says, "Get Skype for Windows Desktop." For Mac users: Go to this link: http://www.skype.com/en/download-skype/skype-for-mac/. Click on the green button that says, "Get Skype for Mac." The Skype download should start automatically and the installer will guide you through how to install the program. After the program is finished installing, open up Skype. If you have trouble finding the program, follow these instructions for Mac or PC. For Windows users: Press your Windows key (left of Alt key), type "Skype" and press Enter. For Mac users: Open up Finder, search for "Skype," then click on the program. If the program does not show up after searching for it, try installing the program again. In the left side of your screen, you will see a list of contacts if you have added any. Click on the name to open up a conversation with that person. If you haven't added any contacts, you will first have to add at least one. Ask for a friend's Skype ID, click Contacts in the upper left of the window, click Add Contact in the dropdown menu, then type your friend's Skype ID. To start a video call, you must first be in a conversation with a contact. The instructions are slightly different for Mac and PC users. For Windows users: Click on the icon in the upper right corner of the window that looks like a video camera. It should be a blue circle with a white video camera inside. For Mac users: Click on the icon in the upper right corner of the window that looks like a video camera. It should be a green circle with a white video camera inside. Depending on your version of Skype, the icon may instead simply say, "Video Call." You may be asked for permission for Skype to use your video camera, click "Allow" if you are comfortable with Skype having access to your camera. End the call by pressing the red button on the bottom of the video call window. The icon looks like a red circle with a white phone inside of the circle. You may need to move your cursor around the inside of the video call window to reveal the hang-up button.

Problem: Write an article based on this summary: Use a cholesterol-free egg substitute. Replace fats with fruit purees. Use banana in recipes. Include soy-based products in your baking. Lower baking times and temperature.

Answer: To remove cholesterol from dessert recipes while baking, substitute for the eggs with a cholesterol-free alternative. A whole, regular egg has 210 milligrams of cholesterol, while egg whites and egg substitutes (e.g. Egg Beaters) contain none. Eggs generally serve as the binding agent in recipes and must be replaced in specific ratios. One large egg should be replaced by two large egg whites or 1/4 cup of egg substitute. Fruit purees can be a sweet, light substitute for fats in recipes, such as butter and shortening. Fats usually add moisture to baked desserts, which results in a lighter, finer texture. Apple sauce and pureed, canned pears are good alternatives that do not significantly alter the taste or appearance of your baked goods. Replace fats cup-for-cup with fruit purees. Keep in mind that even though vegetable oils contain fats, they don't have cholesterol. Mashed banana can be used to replace eggs in recipes (1/2 cup for 1 egg) to lower cholesterol. Bananas also add sweetness, bind the mixture, and provide potassium and magnesium. Note that bananas will lend their distinct flavour to the recipe, so make sure this addition will work in your dessert. Soy protein is a good alternative for many foods that are high in animal fats. Whenever possible, use soy as a substitute for its cholesterol-heavy counterparts in dessert recipes. For instance: Substitute soy nut butter for butter Use soy milk instead of regular milk Use soy cheese in place of regular cheese. Low-cholesterol recipes are often likely to bake faster than regular recipes because of the lower fat content. Try lowering the recommended temperature of the oven by 25 degrees, and start checking your dessert 510 minutes before it should be done baking. Check your baked goods for lightly browned edges or a springy texture to make sure they are done.

Problem: Write an article based on this summary: Fill a bucket with hot water. Add a cup of distilled white vinegar. Mop the tiles with the vinegar solution. Rinse the floor with fresh water.

Answer: For most floors, one or two gallons of water will suffice. If you need to clean a larger area, you can add an extra couple of gallons incrementally. The warmer the water, the better it will be for loosening stuck-on dirt and grime. Before you start mopping, make sure you've cleared the floor of all removable furniture, appliances and other objects that might get in the way or be damaged by water. If the bucket is too big to fit under the sink, try filling it your bathtub. Aim for a ratio of roughly to 1 cup of vinegar for every gallon of water. Swish the vinegar solution gently to make sure it's blended. Vinegar is mildly acidic, which makes it useful for dissolving hardened residue. Diluting the vinegar will prevent it from bleaching the color or wearing down the finish of your floor tiles. Other high-potency types of vinegar, such as apple cider vinegar, will also get the job done. Work your way across the tiles, mopping in a circular or side-to-side direction. Make sure to spread the vinegar over the entire surface of the floor. Don't forget to run the mop beneath nearby furniture and along the baseboards. As you mop, you should be able to see the results of the vinegar right away. Be careful not to saturate bordering wood or carpet flooring with the vinegar solution. Empty the bucket and refill it with clean, warm water. Go back over the floor once more, wringing out and rewetting the mop every few feet. This will help clear the tiles of loose residue and any remaining traces of vinegar. Soak up excess water with the mop, a squeegee or an absorbent towel, then allow it to air dry completely. If you skip the rinsing step, the dingy water will dry on the floor, leaving behind streaks and splotches. Making sure that the grout has a chance to dry out is essential for preventing the growth of mold and mildew, which thrive in warm, moist spaces.

Problem: Write an article based on this summary: Administer flea medication obtained from your vet. Give your pet a flea bath or a flea dip. Try a spray or powder. Never use a dog product on a cat or vice versa.

Answer:
If you haven't already, talk to your vet about treatment options for your pet. These may include topical treatments, oral medication, or injections. These will kill the fleas on your pet and prevent reinfestation. Again, keep in mind that not all of these treatments work. Talk to your vet about the best treatment for your pets. This can kill the fleas that are currently on your pet, though it will not prevent them or do anything if there are fleas in the environment that jump back on to your pet. Look for a pet shampoo or dip that will kill fleas, larvae, and eggs. Take extra care to wash your pet's head after you've washed his body. Fleas might try jumping onto the head to avoid being washed. Be sure to follow the directions for use and frequency and completely rinse the product off of your pet. DO NOT use dog shampoo or dips on cats. Keep in mind that these types of product will cleanse the pet, but they do not have persistent action to stop the pet from becoming reinfected. You must use another product (such as a spot-on treatment or collar) to prevent reinfestation. Flea sprays and powders, available at pet stores, are applied to the pet's fur. They may need to be worked in to reach the skin to kill the adult fleas. Follow the instructions on the package for proper use. Flea control products are specially formulated for use on a certain type of pet. They are not interchangeable. Do not use a dog-formulated product on your cat, and vice versa.
