article: Unfortunately, most grease fires happen when someone steps away just for a moment. Grease fires can happen in less than 30 seconds, though. Don't turn your back on hot grease. Cooking with a lid both contains the grease and cuts it off from its would-be oxygen supply. A grease fire can still erupt with the lid on the pot if the oil is hot enough, but it's far less likely to happen. Get into the habit of making sure these items are within easy reach when you're cooking with grease. If a fire erupts, you'll have at least three different ways to immediately snuff it out. Find out the smoking point of the particular oil you're using, then use a clip-on thermometer to monitor the temperature as you cook. If it gets to close to the smoking point, turn off the heat. If you see wisps of smoke or smell something acrid while you're cooking with oil, immediately turn down the heat or remove the pot from the burner. The oil won't immediately catch fire once it starts smoking, but smoke is a danger sign that it's getting close to that point.

article: Nettles are covered with tiny hollow hairs, filled with irritating chemicals. When you brush against these hairs, the tip breaks off and releases these chemicals, causing the sting. To harvest nettles with bare hands, you'll need to learn to touch the plant without breaking the hairs. Nettle plants vary greatly. Some have almost no hairs, while others are covered in them. There is one useful pattern you can use, however: plants in full shade tend to have many fewer hairs than plants grown in the sun. Typically, a nettle has stinging hairs mostly on the underside of the leaf, and little to none on the top surface. These should all lie along the leaf pointing from the central cleft to the outer edges.  Don't assume your plant will match this description. Nettle plants have a high degree of variation, and the name "stinging nettle" actually describes at least two species. Look for the hairs with your own eyes. The stem also has hairs. These angle down or up the stem on some plants, but poke out perpendicular to the stem on others. If your plant looks like the last type, it's best to avoid the stem completely. It's easy to get stung by another leaf when you're focused on the one you're grabbing. Stay near the top of the plant, where the leaves are smaller and less likely to brush against your hand from above. Nettles often grow in dense patches, so keep an eye out for nearby plants swaying toward you. You're less likely to break the hairs if you grasp from the base of the hairs, rather than run your hand into the tips. If the stem looks safe to grab (with angled hairs), aim for a spot just below the leaf. This will make it easier to pluck the leaf off the plant. A quick, firm grasp is your best bet to avoid breaking the hairs. If you're too gentle, you'll almost always snag a hair and break it. Once pinched, you can twist the leaf and pluck it off the plant. There's no guarantee you won't get stung even with this method. Try this at your own risk.

article:
To calculate the population density, you will divide the population by the size of the area. Thus, Population Density = Number of People/Land Area.  The unit of land area should be square miles or square kilometers. You can use square feet or meters if you are finding the density of a smallish space. For most professional and academic demographic purposes, though, you'll need to use the standard square miles or kilometers. The unit of population density is people per unit of area. For instance, 2000 people per square mile. You should know the population and the surface area of the region. For example: if there are 145,000 people in the city of Auburn, and the urban area covers 9 square miles, write 145,000/9 square miles. Use long division, or just use a calculator. In our example, 145,000 divided by 9 would show that the population density is 16,111 people/square mile.
