Article: These pumps use approximately 30 to 45 percent less energy than a regular pump and you can actually use them less frequently. The speed can be regulated, which means you can turn the pump down on most days and only run it at higher speeds when you need a thorough cleaning.  Additionally, high efficiency pumps are able to circulate pool water better than traditional pumps. This will save you even more money, since well circulated water causes less daily stress on the filter. A significant amount of energy can be saved if you regulate the pump’s daily cycling with a timer. Set your pump to run several short cycles throughout the day rather than running for long stretches of time. Your pool will actually be cleaner by doing this, especially if you deal with a lot of debris.  The shorter, more frequent cycles allow debris to be filtered out of the pool faster because it prevents it from building up. It also puts less stress on the filter itself.
Question: What is a summary of what this article is about?
Get a smaller, high efficiency pump. Use a timer to control the pump.

Problem: Article: If you want to make the most of your shelf space, you should try to stagger items based on size. Place larger items in the back, with smaller items closer to the front. That way, you can still see the items displayed in the back without being blocked from view by those items in the front. Try to group similar items together. For example, you might include a large photo of your family on vacation in the back, with some small mementos from the trip placed in front of the photograph. Try to include a wide variety of items when decorating your shelves – different colors, textures, shapes, and sizes. If you include a lot of similar-looking items, the decorative effect might be a little bit dull. Mix it up with some smaller items, some larger objects, and a variety of textures. For example, you might want to display a tall vase with some fresh cut flowers next to a small candle or a decorative box that you can store various baubles in. Or place a small, ornate photo frame next to a larger indoor plant in a decorative pot. You don't want your shelf to look too cluttered with all of your decorations. Spaces that are too “busy” really detract the eye from the important things being displayed.  Leaving some empty shelf space can also help your life and your home feel less cluttered in general. You want to be able to enjoy the things you do put on display on the shelf, so make them stand out by leaving some empty space around them. For example, if you have nice photo of your family with a multitude of smaller objected stacked all around it, your eye will be drawn away from the photo as you focus on the other items.
Summary: Put larger items behind smaller items to increase display space. Decorate with a variety of shapes and sizes. Leave some empty space.

INPUT ARTICLE: Article: This cut allows you to take out a branch without damaging the bark as much. If you don't use this cut, you could rip or tear the bark. Start by making a cut on the underside of the branch 6 to 12 inches (15 to 30 cm) away from the trunk. Cut 1/4 of the way into the branch.  Make another cut on top, 1 inch (2.5 cm) further out from the trunk than the first cut. The branch may fall off before you finish this cut. You should cut until the limb comes off. Cut the stub off at the trunk. Saw from top to bottom just beyond the swollen ring of bark at the trunk. When you see brown foliage at the end of the branch, that's an indication it's died. In that case, cut the branch right at the stem with clippers or a saw and pull the branch out.  Lopping shears are a good choice for this purpose, as they have long handles that give you leverage. However, if the branches are larger than 1 inch (2.5 cm) in diameter, you can use a handsaw or a chainsaw instead. Another option is to make the cut at a healthy lateral branch instead of the trunk. A lateral branch is a main branch that grows off the trunk. Diseased branches also need to be pruned so diseases don't spread to the rest of the tree. When you find a diseased branch, cut it all the way back to the stem or a lateral branch.  One common disease for this group of trees is needle blight, which results in yellowed or brown needle tips that progresses further down the foliage. They may also look dried out. On the branches, look for black fungal spots that may also curl out from the bark.  Make sure that you dispose of any diseased branches properly in your trash or curbside yard waste program. Then rake up the needles under the tree and dispose of these as well, as they may contain spores. This will prevent it from spreading. It's also best to avoid pruning diseased branches while they're wet because that's when fungal spores are most active. If your tree is damaged by a storm or ice, cut away the branches that are damaged. Prune them back to the stem or a lateral branch within the tree. Damaged branches drain the tree's resources and won't provide new growth.

SUMMARY: Use the 3-branch cut when removing a large limb. Cut out dead branches to the stem. Look for diseased branches to prune. Prune away damaged branches when they break.

Using a trampoline can be very dangerous, so it is best to train first in a safe environment. Training happens in lessons for competitive sports including gymnastics and diving. There, a teacher or coach can help you learn how to use a trampoline properly.  Improper use of a trampoline can lead to severe head and spinal injuries. Flipping increases your chances of this. Flips should not be attempted until you feel completely comfortable using a trampoline. The ideal area to place your trampoline is a level surface away from any obstacles, including trees, fences, and lawn equipment. Place the trampoline on absorbent ground such as a grassy lawn, wood chips, or sand. Add padded mats for extra protection. Proper cushioning shields you when you fall. The motion and momentum from flipping makes bone fractures more likely. Safety padding is brightly-colored shielding that goes around the edges of the trampoline, covering the frame and springs. Order padding online or choose a trampoline that has the thickest padding possible. The frame is a hard surface and can also cause fractures if you land on it. Never get on the trampoline until you have ordered a net and placed it securely around the trampoline. When you fall, the net will slow your momentum or catch you before you hit the ground. This is important in flipping because of all the movement you'll be doing. Bigger trampolines have enough space for more than one person, but this isn't safe. Besides the difficulty in controlling your motion when multiple people jump, the other person can easily bump into you and send you flying. The lighter person on the trampoline is more likely to get hurt. Jumping off while flipping creates a heavy impact that can damage your knees and break your ankles, but this applies to regular jumping too. Instead, stay in place until you come to a halt. Walk to the edge of the trampoline and step or slide off.

One-sentence summary --
Get supervised training first. Choose a cushioned area. Install safety pads. Enclose the trampoline in a safety net. Limit it to one person on at a time. Don't jump off.
