Article: Once the male dog has been deemed acceptable for breeding his semen will need to be collected. Male dogs will become aroused in the presence of a female dog in heat, which is the prime time her body emits pheromones or chemicals that excite the males. When he attempts to mount, or breed, with the female the penis is redirected into an artificial vagina into which he ejaculates.  In some cases a female at the correct stage of heat is not available. Frozen cotton swabs that were wiped in the vagina of a female dog at the peak of heat can be thawed and swiped on the tail end of any dog, which causes the male dog to respond. In some cases semen can be collected and stored before a dog dies to be made available after his death; in others injury may make it impossible for a male dog to breed naturally yet he may still be able to produce semen. After the semen is collected, the sperm cells in it will be examined under a microscope to make sure they are normal. This means that there will be sufficient numbers, shape, and activity. Chilled semen is used within 24 hours or else it will need to be frozen. Semen is stored in liquid nitrogen containers at subzero temperatures. This way semen can be used years later. The best success rate comes from use of fresh semen. With chilled semen the success rate drops to 59-80% and with frozen it falls to 52-60%.
Question: What is a summary of what this article is about?
Collect the male dog's semen. Have the semen evaluated. Chill or freeze semen that it not used immediately.

Problem: Article: If you know you will need to stay awake for a long period, make sure to get plenty of rest beforehand. The best plan is to sleep very well the night before, but even a short nap before having to stay awake can help. If you are staying up so that you can work at a computer or other in another situation where you concentrate on something for long periods, make sure to give your eyes a break. Every twenty minutes or so, set aside a minute to look away from the screen to rest your eyes. This helps you retain your focus and resist fatigue. A brief nap can actually increase your energy and alertness when you are trying to stay awake. However, you should only nap for 5-25 minutes, and you should not take more than one nap a day.  Make sure to set an alarm clock—or several—so that you will wake up from your nap. You may also feel groggy when you first wake up from your nap, so give yourself some time to get back to normal. If you can’t fall asleep, even closing your eyes and resting for 10 minutes can reinvigorate you. Even if you plan well ahead of time, staying awake for 24 hours or more will leave you feeling very fatigued. However, some research shows that you can make up for a lack of sleep by sleeping more afterwards. The day or night after you stay awake for a long period, give yourself the opportunity to sleep longer than usual. Most adults need 7-8 hours of sleep a night.
Summary: Plan ahead. Rest your eyes. Take a short nap. Repay your sleep debt afterwards.

INPUT ARTICLE: Article: It's best to can food that you like. There's no point in canning gallons of something you don't like or your family won't eat, unless you plan on giving your canned goods as gifts or selling them. If you grow your own fruits and vegetables, choose a food you have a lot of. If your peach tree has been particularly fruitful this year,  can your peaches rather than the two strawberries your plant produced this season. Canning is a great way to preserve those extra tomatoes or apples at their peak. Some foods require more handling, time, and processing than others. If you're just beginning to can, start with one batch of tomatoes or jam, not 40 pounds of apples. You can always do more as you grow comfortable with the process and decide you like it. Remember that while cherries can be canned, you'll have to take out every pit first. Fruits and vegetables should be firm and ripe, free of bad spots and mold. Foods need not be beautiful to can them. If you are growing or buying tomatoes, you may find yourself with "process tomatoes" (tomatoes with more bulges and seams than might sell well in the supermarket) or pickling cucumbers.

SUMMARY: Choose what food you will can. Start with something fairly simple if you've never canned before. Choose food in good condition.

Fold over each of your fabric pieces so that the short ends are lined up and the right sides (print or color sides) are facing each other. Then, sew along the short edges to form each piece into a circle. If you prefer, you can wait to add a seam on the skirt until after you have sewed all of the tiers together. This may be a better option if you are planning to do more than three tiers. Take your top tier piece and fold over about ½” to 1” (depending on the width of your elastic) of fabric of one of the long edges so that the wrong sides (non-print or non-color sides) are facing each other. This will be the waistband of your skirt. Sew along this edge to create the waistband.  Make sure to leave enough space to add your elastic in later. Leave a small 1” to 2” gap in the seam to insert the elastic. It is easier to hem the bottom of your skirt before you start to gather your pieces and sew them together. Fold over about ½” of fabric of one of the long edges of the bottom piece (your largest tier). Then, sew along this edge to create the bottom hem. You will be sewing the tiers together, but first you need to gather them. You will start by gathering the bottom tier and sewing it onto the bottom of the middle tier. To gather the bottom tier, sew a baste stitch into the top of the bottom tier (not the edge that you just hemmed). If you want, you can sew a permanent stitch over the baste stitch when it is gathered to your liking. However, sewing the middle tier to the bottom tier will create this permanent stitch, so it is not absolutely necessary to stitch over the baste stitch. Line up the edges so that the right sides of your fabric are facing each other. Then, pin along these edges about ¼” to ½” inch from the edge of the fabric.  Be sure to line up the center seams on the bottom and middle tiers. If you did not create the center seam yet, then make sure that the ends are even. You can adjust the gathering before you start pinning the pieces together to make sure that the pieces are the same length. After you have pinned all the way around the pieces, sew the pieces together, removing the pins as you sew. Next, you will need to repeat the baste stitch on the top of your middle tier, but this time you will be gathering the fabric so that it is the same size as your top tier piece. Add your baste stitch and then adjust until the middle tier piece matches your top tier piece. After you have gathered the middle piece to match the top tier piece, begin pinning the wrong sides together. Pin all the way around the pieces and then sew the two pieces together.  Make sure that you line up the center seams on the middle and top tiers. Remove the pins as you sew. If you have more than three tiers, then you will need to continue to baste and stitch until you have added all of your tiers.
