Problem: Article: In very basic terms, the Fischer-Tropsch process adds high temperature, high pressure, and a heavy metal catalyst (like iron or cobalt) to the typical biomass gasification process. As a result, it can be used to create liquid synthetic gasoline out of biomass like wood pellets or organic trash. The high heat and pressure convert the biomass into a mix of carbon dioxide and hydrogen, at which point impurities can be filtered out. Then, the introduction of a heavy metal catalyst turns the carbon dioxide and hydrogen into long-chain hydrocarbons that are cooled and condensed into a liquid. Fischer-Tropsch has great DIY appeal because, unlike biomass gasification that produces a combustible vapor for immediate use, it produces liquid fuel that can be stored and used as needed. However, while it's theoretically possible to replicate using widely-available materials, creating a Fischer-Tropsch converter is likely beyond the capabilities of most people. It relies on temperatures of at least 300C (572F) and preferably 1,000C (1,830F), and pressures of up to tens of atmospheres. This makes it extremely challenging--and dangerous, due to the risk of an explosion--if you don't have advanced mechanical and scientific knowledge. If you're eager to try building a Fischer-Tropsch converter, research it thoroughly and study several conceptual designs. If you're not a mechanical engineer, you'll almost certainly need to find one to help you construct the converter. You may also need to check with local authorities to see if this is legal to build where you live. While the basic building materials are widely accessiblethings like steel piping, pressure gauges, etc.you need expert precision and knowledge to build a Fischer-Tropsch converter effectively and safely. Putting combustible materials under high pressure creates a major risk for explosions if the converter isn't built and maintained properly. A Fischer-Tropsch converter lets you create liquid synthetic gasoline out of widely available materials like wood chips, so it is potentially valuable in an emergency situation. However, for general use, it is far more expensive to create fuel this way than to purchase typical gasoline. So, unfortunately, this isn't a "magic bullet" replacement for gasoline derived from crude oil. Fischer-Tropsch fuels, however, do burn cleaner and create less environmental pollution than standard gasoline.
Summary: Learn how Fischer-Tropsch creates liquid fuel out of biomass. Accept Fischer-Tropsch's limitations as a DIY project. Get detailed plans and expert assistance if you wish to proceed. Don't expect to save money on fuel this way.

Problem: Article: If a long distance relationship is working, you should feel as much or more trust and satisfaction as people in geographically convenient partnerships. Think of your partner. If you get a warm, thrilling feeling, that's a good sign. Some other questions you can ask yourself to check on your feelings include: Am I happy? Do I feel fulfilled and supported by this relationship? Do I feel listened to, cared about, trusting, and open? Is it a pleasure to talk to your partner? Do you love sharing details of your day? Do you love hearing details of your partner's day? All of these are good signs that you are actively building a loving relationship. Is your conversation affectionate? Do you tell your partner what you appreciate about them, and do they do the same for you? Every time you share appreciation you are building your attachment. How are your conversations about physical intimacy? Couples in long distance relationships often have better communication about sex than couples who live nearby. If you have frank, happy conversations about the things that you like and don't like, you're building a healthy sex life. Can you have conversations about things you remember doing together? Things you haven't tried yet, but would like too? If you both feel free and comfortable sharing fantasies and desires, that's a great sign. Conversely, if you feel like you can't talk about sexual things, or if one of you is always demanding photos and messages that the other isn't comfortable with, your relationship might not be working out. Long distance relationships only work with great degrees of trust. In fact, the best long distance relationships have a stronger element of trust than other relationships. Being long distance means you can't check out one another's stories. You have to take your partner at their word. Ask yourself: Do you trust your partner? Do you feel like your partner trusts you?
Summary: Check in with your feelings. Consider your communication style. Ask yourself how you're handling the long distance intimacy. Examine the trust you share.

Problem: Article: Talk while placing your hand across your nose. Then, do the same thing with your hand flat on your chest. If you feel lots of vibrations in your nose for both exercises, then you have a nasal voice. More vibrations in your chest indicate that you have a chest voice. Equal vibrations in both areas means that you have a balanced voice naturally capable of a wide range of notes. Singers with a chest voice often find it easier to hit lower registers. If you have a nasal voice, it may take more time and effort to consistently hit low notes, but it is still possible. " Select a note in the middle of your vocal range. Then, start singing "mee" and continue on for as long as you are comfortable with. Keep the "mee" sound clear, clean, and without scratchiness. Then, attempt to move down notes in your range so see how far you can go. As you sing "mee," pay attention to your resonance. You should feel more facial vibrations as you head into lower notes. Don't be concerned if your volume decreases when you sing "mee" in a lower register. This is normal. Vocal coaches are trained singers who can help you with your technique. They can help you develop your ranges properly and improve your tone without damaging your voice. Find a vocal coach near you by contacting music schools or the music departments at colleges in your area. A professional vocal coach can also point out weaknesses and suggest ways to improve. Not all singers are meant to hit the lowest notes. Continue to work on your range, but stop if your voice feels scratchy or sore. It's also helpful to spend time developing the notes in the middle of your range, instead of continually trying to extend it out.
Summary: Identify your natural register. Practice holding lower and lower notes in your range while singing "Mee. Work with a vocal coach. Accept the natural limits of your voice.

Problem: Article: Mix the baking soda and water in a bowl until they are well-combined. You are looking for a mixture with a toothpaste-like consistency. If the mixture is too thin, then just add more baking soda until a thick paste forms. Let the paste set for 10 to 15 minutes. For tough stains, let the paste set for longer like 30 minutes to an hour. Use a scrub brush to do this after the paste has set for the allotted time. Scrub in a vigorous back and forth motion until they are gone. Use a toothbrush to clean small crevices. If the stains remain, then you may need to repeat steps one through three again. Wipe until any and all paste, debris and grime are removed. Then use a clean, dry towel to wipe your shower down until it is completely dry.
Summary:
Mix 3 parts baking soda to 1 part water to form a paste. Apply the paste onto the stained areas with a sponge. Scrub the stains. Wipe the area clean with a damp towel.
