Instead of reaching for the roll of paper towels, use a hand dryer to save trees and water. To replace the paper towels that we discard on a daily basis, 51,000 trees have to be cut down every day. To produce one ton of paper towels, 17 trees are cut down and 20,000 gallons of water are required. Using hand dryers as opposed to paper towels cuts down significantly on waste. On a global scale, our discarded paper towels result in an estimated 254 million tons of trash every year. In the United States we consume over 13 billion pounds of paper towels every year. While thoroughly washing your hands is the best way to prevent the spread of germs, drying your hands also decreases the spread of bacteria. According to the CDC, germs are more easily transferred to and from wet hands. If you wash your hands and do not dry them, you usually end up with water stains all over your clothes. Use a hand dryer to prevent this from happening. While hand dryers can help reduce your carbon footprint, they still have an environmental impact. They require electricity to run, and thereby play a role in carbon dioxide emissions. Drying your hands with the typical 2,200 watt warm air-dryer three times a day for one year produces 26.61 pounds of carbon dioxide emissions. To evaluate the carbon footprint of using hand dryers, also think about how your local electric company generates electricity. The more coal it uses, the more carbon the dryer produces. Researchers have concluded that paper towels are the more hygienic and sanitary choice. Here are some of the main reasons why hand dryers are less effective at decreasing the spread of germs: Dryers in public places are rarely cleaned. People often stick their hands in the dryers or on the rim, leaving bacteria on the surface. The dryers can blow bacteria onto other surfaces and onto people using them. In a study published in the Journal of Hospital Infection, researchers determined that jet dryers left 4.5 times more bacteria in the vicinity than warm-air dryers, and 27 times more bacteria than paper towels. Other researchers, however, have questioned the methods employed in the study.

Write the dates of your exams in your calendar. You might want to put a star beside them to indicate their importance. Then, figure out how many days you have left before your exams. Divide the number of days left before exams by the number of subjects you need to prepare for. Now you know how many days you have available to prepare for each subject. Use your textbook and learning materials to determine the specific topic areas within each subject. English Literature, for example, may be broken down into the different books you are studying and then further into chapters, themes, or quotes. Highlight or circle the topics using different colours. Figure out how many topics or sub categories you have for each subject. Then, divide up the time you have for the subject into study blocks for each topic. If you are currently employed, you should review your work schedule for the upcoming weeks. Figure out where you can schedule study-time between your shifts. If you have a lot of upcoming shifts, consider working less so that you have more time for revisions. You need to figure out when your studying may be interrupted by social events or holidays, so that you can plan accordingly. If it looks like there will be a weekend when you are unable to study due to a social obligation, try to put in your revision time beforehand.

Adding salt to beaten eggs starts breaking down the proteins, releasing moisture and creating a less uniform consistency in the egg mixture. This means that the eggs will temper less evenly when you add broth. Season the broth after the eggs have been tempered and added into the soup, not before you temper the eggs. Ladle out some of the broth, spooning in a small amount to the bowl with the eggs in it. Whisk the eggs vigorously while you add the liquid. Count to ten before you add another spoonful and allow the temperature to come up gradually. Try as best you can to only use broth to temper the eggs. Depending on what kind of soup you're making, it can be hard to avoid little chunks of vegetables or meat. It's fine if you get a bit of veg in there with your eggsit's all going together anywaybut the eggs will whisk easier with just broth and egg, and the eggs will temper more quickly. Continue adding broth in small amounts and put your hand on the side of the bowl to check for the temperature. Look closely for steam. If you're doing it properly, the eggs should still be perfectly liquid, but should be steaming and warm, meaning that they're tempered properly. When you see steam, your eggs are tempered. When the bowl is steaming as much as the pot with the broth, you can pour the tempered eggs directly into the soup. Stir the eggs around to enrich the broth with the tempered eggs. The broth should thicken somenot muchand will take on a cloudier, slightly yellowish or milky color.

in the fall so your tree can adapt and grow strong. If you plant in the fall, your trees will have adequate time to develop their root system and get stronger over the colder months. High temperatures and direct sunlight can harm your trees and make it hard to root into the soil. Both sweet and tart cherries grow the strongest if they are planted in the fall. If you decide to plant your cherry tree in the spring, be sure to water it well throughout the spring, summer, and fall. before you plant your trees. Remove weeds and mix in well-rotted compost material to fertilize your soil. Leaves and tree trimmings work well as raw composting materials. Always use well-drained soil to avoid waterlogging your tree. You can improve your soil's drainage by building raised beds or adding more rotting organic matter to existing soil. Your pH level will vary depending on soil type and climate conditions. Test your pH level by purchasing a basic soil test kit from a home or garden supply store. Take 3-5 samples with your kit, and follow particular instructions listed on your kit. Your kit will inform you of any nutrient deficiencies. You can add sulfur to increase acidity or add lime to reduce acidity. Both sweet and tart cherries need ample sunlight in order to grow to full size. Sweet cherries in particular need as much sunlight as possible, while tart cherries can grow without quite as much sun. Full sun exposure will also help prevent pests and diseases. For example, plant your trees on top of hills that face the morning sun. Avoid placing your cherries near other trees or buildings that cast shade. Make sure your trees have enough room to root down and grow healthy. If you plant your trees too close together, your trees will compete for sunlight and nutrients from the soil. For sweet cherries, space dwarf trees 510 feet (1.53.0m) apart and adult trees 3540 feet (1112m) For tart cherries, space dwarf trees 810 feet (2.43.0m) and adults 2025 feet (6.17.6m)
