In one sentence, describe what the following article is about: Look on the right side of your radiator near the floor to find the valve. Use a screwdriver and turn the screw counter-clockwise until it’s loose. Set the screw aside in a safe place so you don’t lose it.  Not all lockshield valves will have a screw. Check the valve beforehand to determine if you need a flathead or Phillips head screwdriver. Lockshield valves have caps that don’t control anything when if you try to turn them. Remove the cap to access the actual valve underneath. When the screw is removed, simply lift the cap off the valve and set it aside so it doesn’t get lost. If your valve cap had a screw, store the cap and screw together. Grip the top of the metal valve with a sturdy pair of pliers and turn it clockwise. Keep turning the valve until it doesn’t go any further. When it’s all the way to the right, the radiator is off. The metal valve may be hot so do not touch it with your bare hands.
Summary: Remove the screw from the valve cap if there is one. Take the cap off of the valve. Turn the valve clockwise with a pair of pliers.

This is likely what you want to do if you are selling your Nook, but if that is not your plan, only do this if you are advised by a professional that you have no other option. It is recommended that if you are keeping the device, you back up your files before resetting to factory settings. The easiest way to do this is to download the Nook Reading App to your PC. The app will then sync with your Nook when you log into your account, thus storing your Nook Library on your PC. You can find the app in Apple's App Store, in Google Play, and in Windows Store. You cannot complete a factory reset without being connected to a Wi-Fi network. It is best to connect to your own private network, but it can be done on a public network, as the information should be encrypted by Barnes and Noble's system. From here, you will be able to access the settings that will allow you to begin the process of doing a factory reset on your Nook 1st Edition. Once you confirm this step, your account and information will be unregistered from the Nook. As of now, your Nook has been cleared of your registration and account. After this, you will have to confirm twice. Once the process completes, your Nook will be completely cleared of all of your content and settings. It will be as it was the day you purchased it. This applies only if you are keeping your Nook and had to do a factory reset to resolve a software issue.
Summary: Consider whether you really need or want to do a factory reset. Connect to a Wi-Fi network. Tap Settings from the Home menu. Go to Devices, and then tap Unregister Your Nook. Click Confirm to unregister your Nook. Tap Reset to Factory Settings. Register your Nook again by following the on-screen prompts.

In one sentence, describe what the following article is about: . Frogs are especially susceptible to poisoning from pesticides, herbicides, synthetic fertilizers, and other common garden chemicals because their hydration and respiration takes place through their porous skin. If you want to attract a healthy frog population, start by using organic gardening practices.  Instead of using synthetic fertilizer, encourage growth through picking nutrient-rich soils that are appropriate to each plant, rotating your crops to keep your soil rich, and using organic fertilizer when necessary. Keep in mind that once you've attracted frogs, you shouldn't have any need of chemical pesticides since a single frog will consume more than 10,000 bugs a season. You want to attract the right kind of frogs. Non-native frogs will compete with local ones for food and shelter. Sometimes they'll even eat local species. Their populations are also generally difficult to control because they have no natural predators.  Identify the species of frogs in your yard or garden to be sure that they're not invasive. Invasive.org has a list of dangerous non-native wildlife that can be searched by animal type and region.  If you do find invasive species of frogs in your yard or garden, contact your local government environmental agency, like your state's DNR, or a nonprofit conservation group, like the National Wildlife Federation, for advice and support about how to remove them responsibly. Frogs like to hide in tall grass and are frequent victims of lawn mowers. Be sure that you can see any rogue amphibians in your path by keeping the grass in your yard or garden well-trimmed. Most male frogs hibernate in water over the winter. A thin layer of ice will not harm them. However, if their water source is completely frozen, they won't survive. Protect any dormant amphibians by putting a pan of hot water over thickening ice. Many flowers and vegetables are poisonous to frogs. Protect the amphibian population in your yard or garden by either not planting species that are toxic to them or by planting them well away from your intended frog habitat.  Vegetables that are dangerous for frogs include eggplant, rhubarb, snow peas, and potatoes. Flowers that are toxic to frogs include honeysuckle, azaleas, hydrangeas, daffodils, and hyacinth.
Summary:
Avoid using chemicals Keep out invasive species. Keep your grass short. Thaw water sources when necessary. Avoid plants that are toxic to frogs.
