In one sentence, describe what the following article is about: While many midwives believe drinking red raspberry leaf tea during pregnancy is safe, others do not think it's safe, so it's always best to consult your doctor before you start drinking the tea. For one, any kind of herbal tea or supplement can have interactions with other medications and conditions, so it's important your doctor knows about it. She can tell whether it's safe to use. Some doctors feel like the tea is not safe to drink in the first trimester of your pregnancy. They believe it can cause contractions leading to miscarriage. Others feel the tea is safe throughout pregnancy. To be on the safe side, limit yourself to 1 cup of tea a day during your first trimester, or don't drink it at all. Once you reach your second trimester, it's considered safer to drink more of this tea. You can drink as much as 4 or 5 cups a day of this tea. Once again, though, ask your doctor before increasing your intake of this supplement. The main reason it is taken is to shorten labor, and some studies have shown it is effective and safe for this purpose. It may also reduce your risk of tearing when you give birth, and you'll be less likely to need forceps or a cesarean section. People also believe that it will decrease your pregnancy pain, increase your milk supply, and decrease your bleeding after birth. In addition, it does supply a number of vitamins, such as vitamins C and E, calcium, iron, magnesium, and manganese, as well as B vitamins. Like any supplement, you may have side effects from this tea. For instance, you may experience nausea or even mild diarrhea. If the side effects are too severe for you, stop taking this supplement.
Summary: Consult your doctor. Limit the tea or don't drink it in the first trimester. Increase your intake later in pregnancy. Understand why it's used. Know the side effects.

In one sentence, describe what the following article is about: This determines the radius of the circle to be drawn. A circle's radius is the distance between the circle's center and outer edge. Put more simply: it is half the diameter. For example, for a 6in (15cm) tall cone, the circle's radius will be 6 inches (15cm). The tool to cut the circle out will depend on the material used. Scissors will work for most materials; with metal sheeting, use metal snips. Be careful when cutting metal; it will be sharp. For something quick and simple, tear off a strip of tape, and place it over the seam created by the overlapping edges. For a nicer finish, lift the top edge, coat the underside with glue, then press it back down again. Either a glue stick or liquid glue will work; tape the cone as it dries, then remove the tape. If making a felt, foam, plastic, or metal cone, use hot glue instead. Fabric glue may work for foam cones as well. If you know how to weld, weld a metal cone shut instead.
Summary: Decide how tall the cone will be. Cut the circle out. Tape or glue the edges down.

In one sentence, describe what the following article is about: For this method, we'll start with a fully-assembled tank, minus the fish, just like in the method above. However, this time, we won't add the fish until the entire cycle is completed. Instead, we'll add biological waste manually as we monitor the water level and wait for the cycle to complete. This method requires a lot of patience, as it requires you to wait for the organic material you add to your tank to decay and start producing toxic waste products. However, it's often considered a more "humane" option as it doesn't expose fish to ammonia and nitrites like the method above does. To begin, drop just a few flakes of fish food into your tank about as much as you'd use to feed your fish will do. Now, simply wait. Over the next few days, the flakes will begin to decay and release waste products (including ammonia) into the water. Use a test kit (or bring a water sample to your local pet store) to test your water for ammonia levels. You want to have a level of at least three parts per million (ppm). If you don't have enough ammonia in your water, add more flakes and wait for them to decay before testing again. Continue to test your water every other day for ammonia levels. As beneficial bacteria begins to grow in your aquarium, it will start to consume the ammonia, reducing the ammonia levels. Replenish them by adding fish flakes whenever the ammonia level falls below three ppm. As the bacteria start consuming ammonia, they'll begin to produce nitrites, the intermediate type of chemical in the nitrate cycle (which is less toxic than ammonia but still harmful to fish). Start testing for nitrites after a week or so again, you can use a commercial test kit or take water samples to a pet shop to do this. Once you detect nitrites, you'll know the cycle has started. At this point, you'll continue adding ammonia as you have before. As you feed the bacteria in the tank ammonia, the nitrite levels will continue to rise. Eventually, however, enough beneficial bacteria will grow to convert the nitrites into nitrates, the final type of chemical in the nitrate cycle (and one that isn't harmful to fish.) When this happens, you'll know the cycle is nearing completion. You can detect this final phase of the cycle by either testing for nitrites (in which case you're looking for a sudden drop), nitrates (in which case you're looking for a sudden spike from a base level of zero), or both. After about six to eight weeks, the ammonia and nitrite levels should decrease to a level that's so low you can no longer detect them, while nitrate levels should plateau. At this point, it's safe to add your fish. However, as in the method above, you'll want to add your fish gradually. Don't add more than a few small fish at a time and wait at least a week or two before introducing your next batch of fish. Consider cleaning the substrate with a siphon hose before adding fish, particularly if you had to add a lot of food. Decaying food or plant matter can become a ticking time bomb. If it gets trapped in the gravel, the ammonia won't enter the water, but if something upsets it, it could release a fair amount of ammonia rather quickly.
Summary:
Assemble and prepare your tank. Add a sprinkling of fish flakes. Test your water for ammonia in a few days. Try to keep the ammonia level at about three ppm. Start testing for nitrites, after a week. Wait for a sudden drop in nitrites and a rise in nitrates. Add fish gradually when ammonia and nitrite levels are near zero.
