Article: A cat that is normally sweet-tempered who becomes irritable may well be in pain. This is a giveaway that there is a problem. The placid cat that suddenly turns aggressive, hisses, and spits rather than let you pet it is probably experiencing pain.   Be alert for a friendly cat, that changes character backs away, arches their back, hairs erect, dilated pupils, ears flattened back, hisses and spits. These are all signs of aggression. Alternatively, you may have a feisty cat who suddenly becomes withdrawn and starts hiding. Indeed, the cat who stops grooming may be in pain. The signs are subtle but a cat's facial expression can tell you a lot about whether it is stressed or not. This is important because a cat in pain is also a stressed cat, and stress signals can be a vital clue. Look for a worried or tense expression on the cat. This could include a furrowed brow or a vacant stare. The pupils are likely to be large and dilated, whereas a cat at rest in normal lighting conditions should have slit-shaped pupils. Some cats may cry more and vocalize when they are in pain. However, many go the other way and become quiet and withdrawn. Be aware that purring does not always mean the cat is happy. Purring can comfort the cat and so even a distressed cat may purr to itself in order to feel reassured and a bit better.

Determine if the cat is acting out of character. Take a look at the cat's face and posture. Notice changes in vocalization.
Article: The melody to "Happy Birthday" is a simple one that everyone knows, so practicing it is easy and you'll know right away if it sounds wrong. The first two notes (the ones that correspond to "Hap - py") are both Gs.  The note you'll want to start with here is the one you get by playing the open G string. Play one note for each syllable in "Hap - py," like this:High E string:----------------B string: ---------G string: 0-0--------- D string:--------A string:--------Low E string:--------  For this section, since there's not an easy way to represent staff music or tablature on WikiHow, we're going to proceed measure-by-measure. For a traditional inscription of the melody, visit a site like Guitarnick.com or start-playing-guitar.com. Each beat gets one note, like this:High E string:--------B string: ----------1G string: 2--0 D string:--------A string:--------Low E string:-------- B gets two beats and the two G eighth notes get one, like this:High E string:--------B string: 0------G string: --------0-0 D string:--------A string:--------Low E string:-------- The third measure is the same as the first, except that the final note is two frets up, like this:High E string:--------B string: ----------3G string: 2--0 D string:--------A string:--------Low E string:-------- The fourth measure is the same as the second, except that the first note is one fret up, like this:High E string:--------B string: 1------G string: --------0-0 D string:--------A string:--------Low E string:-------- The G you start on here is an octave higher than the G you've used earlier. The next two notes descend from this G, like this:High E string:3--0--B string: --------------1-G string: --------- D string:--------A string:--------Low E string:-------- The B you start on here is made with the open B string and the final Fs are played as eighth notes on the high E string, like this:High E string:---------1-1-B string: 0--------G string: ----2------ D string:--------A string:--------Low E string:-------- Start on the open high E string here, like this:High E string:0------------------B string: -----1--3------G string: ---------- D string:--------A string:--------Low E string:-------- Finally, hit the first  fret on the B string to bring the song to a close, like this:High E string:----------------B string: 1--------G string: ---------- D string:--------A string:--------Low E string:--------
Question: What is a summary of what this article is about?
Start with two G pickup notes. Play A-G-C in the first measure. Play B-G-G in the second measure. Play A-G-D in the third measure. Play C-G-G in the fourth measure. Play G-E-C in the fifth measure. Play B-A-F-F in the sixth measure. Play E-C-D in the seventh measure. End on C.
Article: Fumes may emit from the rice cooker as the solvent is dissolved. Because isopropyl alcohol is highly combustible, avoid any and all flames, stovetops, sparks, and cigarettes while you're heating the solvent. Isopropyl alcohol is flammable and cannot be cooked near an open flame or spark. Pour the alcohol into your rice cooker until it is about three-quarters of the way full. Close and turn on your rice cooker to 210–230 °F (99–110 °C).  Although you can heat your isopropyl alcohol in a crock pot, it is not recommended. If your mixture heats to over 300 °F (149 °C), the cannabis will burn and become unusable. Save the rest of your isopropyl alcohol for later. As the alcohol evaporates, you will slowly add more until you have poured in the entire solvent. Wait until the isopropyl alcohol is about halfway evaporated. Continually fill the rice cooker with isopropyl alcohol to three-quarters full. Add a few drops of water (about 10 for every 1 pound (16 oz) added) as the solvent evaporates to keep the oil from overheating. When you have added all of the solvent into the rice cooker and it has evaporated entirely, the oil will be the only liquid left in the rice cooker. It will be the consistency of thick grease and have a dark color when the isopropyl alcohol has dissolved. Dip the syringe into the oil, then slowly pull on the plunger until the syringe is filled with the oil. Remove the syringe from the rice cooker, then cover the top with its plastic tip to prevent spilling.  Do not transfer the isopropyl alcohol into another container. You may need multiple syringes to siphon out all of the oil. Store Rick Simpson oil in the syringes until you are ready to use it.
Question: What is a summary of what this article is about?
Set up a rice cooker in a well-ventilated area. Transfer your isopropyl alcohol to the rice cooker. Check on the solvent periodically and add more alcohol as it evaporates. Wait until the oil develops a dark color and greasy consistency. Siphon the oil out with a plastic catheter tip syringe.
