Problem: Write an article based on this summary: Preheat the oven to 350F (175C) and prepare a 12-inch (30.48 centimeters) pizza pan. Combine the flour, baking powder, baking soda, and salt in a large bowl. Cream the butter, sugar, and vanilla, then add the egg. Mix in the egg. Slowly fold in the flour mixture into the butter mixture. Pat the dough into the bottom of your prepared pan. Bake for 12 to 14 minutes, then set aside to cool on a wire rack.

Answer: You can lightly grease the pan with butter or cooking spray. You can also line it with parchment paper or foil, and then butter it. Sift the flour first to get rid of any lumps, then add the rest of the ingredients and mix them briskly with a fork. Once everything is evenly mixed together, set the bowl aside. Place the butter and sugar into an electric mixer fitted with a paddle attachment. Blend until the mixture is light and creamy. Keep mixing until the yolk breaks up and everything is evenly blended. There should be no streaks or swirls of egg yolk or egg white. Take the bowl out of the electric mixer, and fold the flour mixture in by hand using a spatula. Keep mixing until everything is evenly combined. Make sure that it is covering the entire pan, from edge to edge, in an even layer. Grease your hands with butter or cooking spray to prevent the dough from sticking to your fingers. While the crust cools, work on preparing your sauce and fruit topping.

Problem: Write an article based on this summary: Soak the scallions in 5 parts water and 1 part white vinegar, then rinse. Chop the scallions into small pieces. Spread the chopped scallions on a small, lined baking sheet. Put the baking sheet in the freezer for 3 hours. Transfer the scallions into a sealable freezer bag. Freeze the scallions until you're ready to cook with them.

Answer: Washing the scallions before freezing them is especially important if they're fresh from your garden. Fill a large bowl with the water and vinegar and place the scallions in it. Let them soak for a few minutes before you rinse them off in the sink. That way they'll be ready to use when you take them out of the freezer. Lay the scallions flat on a cutting board and cut off the roots with a sharp knife. The roots are the white parts at the ends of the stalks. Then, bring the knife from one end of the stalks to the other, making swift cuts through the scallions every .25 inches (0.64cm) or so. Use a baking sheet that can fit in your freezer. Line it with parchment paper so the scallions don't stick to the metal. Freezing the scallions on a baking sheet first will prevent them from clumping together in the freezer. After 3 hours, remove the baking sheet. It's OK if they're not completely frozen yet. Open the bag and use a spatula to slide the scallion pieces off the baking sheet and into the bag. Once all the scallions are in the bag, use your hands to press excess air out from the bag and then seal it. Write the date on the plastic bag so you know how long the scallions have been frozen for. If you don't have a sealable freezer bag, put the scallions in an empty water bottle with the cap on instead. Frozen scallions lose their crunchy texture, so avoid putting them on salads or other recipes without cooking them first. To use your frozen scallions, simply remove them from the freezer bag and add them to the dish you're cooking. Frozen scallions can last up to a year in the freezer.

Problem: Write an article based on this summary: Speak with a doctor or a therapist. Ask your doctor about cognitive behavioral therapy (CBT). Ask your doctor about medication therapy.

Answer: Don't rely on self-diagnosis: you may be anxious or obsessive at times, you may be a hoarder, or you may feel an aversion to germs--but OCD is a spectrum, and the presence of a few symptoms doesn't necessarily mean that you need to seek treatment. You won't truly know whether you suffer from OCD until you've been diagnosed by a medical professional. There is no lab test to diagnose OCD. The doctor will base his or her diagnosis on an assessment of your symptoms, including how much time you spend performing your ritual behaviors. If you are diagnosed with OCD, don't worry--there may be no "cure" for the disorder, but there are medications and behavioral therapies that can help you reduce and control your symptoms. You may need to learn to live with your obsessions, but you don't need to let them control your life. The goal of cognitive behavioral therapy--also called "exposure therapy" or "exposure and response prevention therapy")--is to teach people with OCD to confront their fears and reduce anxiety without performing the ritual behaviors. Therapy also focuses on reducing the exaggerated or catastrophic thinking that often occurs in people with OCD. You may need to visit a clinical psychologist to begin cognitive behavioral therapy; a regular family practice doctor or therapist can put you in touch with the right people. It won't be easy, but if you are committed to working hard to control your fixations, you should at least look for CBT programs in your area. Antidepressants--particularly selective serotonin reuptake inhibitors (SSRIs) like Paxil, Prozac, and Zoloft--may be helpful in treating OCD. Older drugs--tricyclic antidepressants like Anafranil--can also be effective. Some atypical antipsychotics, such as Risperdal or Abilify, have also been used to mitigate the symptoms of OCD, either when used alone or in combination with an SSRI. Be very careful when mixing medication. Research the side-effects of any medication before you take it, and ask your doctor whether it's safe to mix a new medication with something you're already taking. Antidepressants alone may help calm your OCD symptoms, but they are not a cure, and they are by no means a fail-proof treatment. A major National Institute of Mental Health study showed that fewer than 50 percent of people become symptom-free on antidepressants, even after trying two different medications.

Problem: Write an article based on this summary: Opt for blind rivets instead of solid rivets. Select multi-grip rivets for situations that require high-strength fastening. Purchase sealed rivets when you need a tight seal that resists leaking. Select interlock rivets for situations that require high-strength fastening. Purchase dome head rivets for standard materials and situations. Opt for flat head rivets to ensure a flush, tight fit. Select a rivet made from the same material as the metal you're joining.

Answer:
Blind rivets can be installed from 1 side and create secure fastenings without the hammering process necessary for solid rivet installation. Standard blind rivets are the most affordable type and are great for holes that are regularly shaped and aligned properly. Use standard blind rivets for securing metal pieces that aren't going to carry lots of weight. To determine the maximum weight your rivets can hold, look at the back of the package for their shear strength. Never use standard rivets for situations that require a water-proof seal. If you're working with important structural joints, don't use blind rivets. Instead, use solid rivets with a pneumatic rivet gun. These rivets have a wider grip range and always completely fill the holes in your metal due to their "bulbing" action. They are best suited for irregular, oversized, or misaligned holes, as well as situations where you're unsure of the optimal rivet length. Multi-grip rivet seals are weather and vibration-proof. Sealed rivets possess an enclosed mandrel (the longer end) that creates a water-tight seal upon installation. They can fasten many kinds of materials and perform well across varying temperature fluctuations and thicknesses. If you don't need a water-tight seal, opt for standard rivets insteadthey're typically cheaper than sealed products. Interlock rivets are best if you need increased pull-out and shear strength, such as in structural applications. They come in large sizes that typically don't fit the smaller rivet guns. Interlock rivets work great for closing big gaps and preventing sheet movement. Dome head rivets are the most common type for pop guns due to their versatility and simple application. They're best used for situations that require reliability and safety. For example, thousands of dome head rivets are used to create the structural frame of modern aircraft. If you're unsure of the applicability of dome heads for your situation, take a look at their packaging to determine the shear strength (listed as weight in pounds) that they can support. Use dome heads when connecting material similar to carbon steel, when the rivet is close to the edge of the material you are fastening. These blind rivets are also called round heads. Flat rivets are countersunk and ideal for soft materials, which are defined as anything easily deformed by temperature extremes or fluctuations, such as polymers, granular materials, and soft biological materials. This is due to their large head that increases their load-bearing area. They are also ideal for situations where nearby rivets and structures make it impossible to accommodate round heads. Load-bearing area is the region that the load-bearing structure can reliably hold up. There are many different kinds of rivet materials. Always match the rivet to the type of metal you're attaching whenever possible. For example, aluminum metal should be fastened with aluminum rivets. If you're fastening leather with a rivet, always use copper, aluminum, or brass. Steel rivets will rust due to leather's tendency to retain moisture. Steel mandrels have a tendency to corrode, and can also create a reaction with surrounding materials. Avoid purchasing rivets that are made from steel mandrels paired with a stainless steel or aluminum body. Purchase a variety pack for a wide selection of rivets of different sizes and materials.
