In one sentence, describe what the following article is about: Microwaves are also used for sterilization. The non-ionizing radiation destroys the microorganisms on the surface of the tools. The microwave stream process is performed on the tools and the heat is used to kill the organisms. It can be used quickly and reliably. You can also use this method at home for things like baby bottles. Hydrogen peroxide use in the form of a plasma or vapor can be used to sterilize. The plasma is made into a cloud of hydrogen peroxide with help from a strong electric or magnetic field. The sterilization phase of hydrogen peroxide is made up of two phases, the diffusion phase and the plasma phase.  For the diffusion phase, put the non-sterile object into a vacuum chamber where 6 mg/L of hydrogen peroxide is injected and vaporized. For 50 minutes, hydrogen peroxide is diffused into the chamber. In the plasma phase, 400 watts of radiofrequency is applied to the chamber, making the hydrogen peroxide a plasma that is made of hydroperoxyl and hydroxyl radicals. These help sterilize the product. The whole process takes about one hour. Ozone gas is a gas generated from oxygen and is used to sterilize medical supplies. The ozone method of sterilization is a newer method that involves a lower temperature. With help from a converter, the oxygen from a hospital source is converted into ozone. To sterilize, a 6-12% concentration of ozone gas is continually pumped through the chamber holding the supplies. The cycle time is about 4.5 hours with a temperature of 85 degrees to 94 degrees Fahrenheit. Chemical solutions can be used to sterilize instruments by soaking in the solution for the required period of time. The chemical agents are peracetic acid, formaldehyde, and gluaraldehyde.  When using any of these chemicals, remember to use a well ventilated area with gloves, eye cover, and gowns or aprons for your own protection. Peracetic acid should soak the products for 12 minutes in temperatures of 122 degrees to 131 degrees Fahrenheit. You can only use the solution once. Gluaraldehyde requires 10 hours of soaking after adding an activating chemical that comes with the bottle. Formaldehyde gas is used for the products that cannot stand heat too high without warping and other damage. In this process, the initial vacuum process removes the air from the chamber. The instruments are loaded and then the steam is let into the chamber. The vacuum continues to remove the air from the chamber as it heats up. Formaldehyde gases are then mixed with steam and pulsed into the chamber. The formaldehyde is slowly released from the chamber and replaced with steam and air.  The conditions have to be ideal for this process with humidity at 75% to 100% and temperatures from 140 degrees to 176 degrees Fahrenheit. Formaldehyde gas is not the most reliable, but it is suggested if EtO is unavailable. It is an old technique that dates back to 1820. It is not often suggested for sterilization because of the gases, smell, and complex processes involved compared to the others available.
Summary: Use microwaves. Try hydrogen peroxide. Sterilize with ozone gas. Consider chemical solutions. Try formaldehyde gas.

In one sentence, describe what the following article is about: It’s not just a cliche--being yourself is likely one of the most crucial steps to attracting your crush. After all, you don’t want your crush to fall for a fake version of yourself and if they are not interested in you, you’ll know right from the get-go that this isn’t the person for you and not to waste your time. For example, if you prefer reading and watching movies over going to your high school football games, don’t pretend that you’re a huge sports fan. You want your crush to like you for you, not the person you're pretending to be. Perhaps the biggest difference between being a senior and a freshman is that everything in the school is new for freshmen. After a few years, most students develop more confidence and ease and this comes naturally with age. However, if you want to attract a senior, you will have to project that same sort of laidback confidence.  Be aware of your body language. Everyone picks up on body cues subconsciously so communicate confidence with good posture, direct eye contact, and an easygoing smile. If you are feeling uncomfortable or insecure, fake it til you make it. Laugh and smile a lot and try to keep things in stride. For example, if someone insults you while you are talking to your crush, make a lighthearted joke about it rather than getting upset or depressed. People are interested in dating those with the same maturity level and so, as you get to know your crush, aim to match their maturity level. Depending on your individual personalities, this may not require all that much effort on your part. Girls also tend to mature more quickly than boys so if you are a freshman girl interested in a senior guy, you may find your levels of maturity are actually similar. If that isn’t the case, practice maturity by being organized, disciplined, and rational in your decision making. Of course, there’s only so much you can do as maturity comes with age, but consciously working towards being mature rather than childlike will definitely make you stand out from other freshmen. Not only will learning about healthy relationships help you know what to expect, but it will also make you more confident and self-assured. After all, if you are trying to attract a senior, you should know the fundamentals of healthy relationships instead of always looking to them for guidance as this will create an unequal power dynamic. Finally, understanding and practicing healthy relationship skills will set you up for safe and fulfilling relationships down the road.  Good communication and mutual respect are perhaps the two most crucial aspects of any healthy relationship. When talking to your crush, be honest about yourself and practice good listening skills. Also be sure to respect them by being considerate of their time and feelings (and make sure they are reciprocating!). You’ll know if you are in a healthy relationship if you feel good about yourself and energized when spending time with that person. Unhealthy relationships tend to be emotionally unfulfilling, draining, and negative so make sure to watch for how you feel when spending time with your crush as that will clue you into whether the relationship is actually healthy or not.
Summary:
Be yourself. Be confident and laidback. Be mature. Learn healthy relationship skills.
