If you have been looking into the numerous types of lasers and laser components http://www.cheapnbajerseyshawks.com/Tim-Hardaway-Jr-Jersey/ , YAG is one of the names that you must have seen quite often. These lasers are indeed very popular, with a wide range of practical applications. So here is what you should know about them, just to broaden your horizons and overall knowledge. As you may already know, a laser is nothing but a device capable to emit light through optical amplification. In a few words, it is all about stimulating the emission of an electromagnetic form of radiation. After all, the term is an acronym from Light Amplification by Stimulated Emission of Radiation. A short classification of these devices would include solid state http://www.cheapnbajerseyshawks.com/Paul-Millsap-Jersey/ , gas, excimer, dye and semiconductor lasers. From all these types, our topic for today would enter the solid-state lasers category. The lasing material is normally distributed through a solid matrix, in our case an yttrium aluminum garnet, hence the YAG short form. It does not take much research in order to notice how the term often receives an Nd: in front of its name http://www.cheapnbajerseyshawks.com/ , which comes from neodymium-doped. What is this Nd:YAG if not a crystal? Of course, the crystal is one of the many laser components, but even so, it definitely makes the central piece, as it determines the features and particularities of the final product. Regularly used in its monocrystalline or ceramic forms, the substance presents the following properties: it makes a 4-level gain medium; it can be easily lamp or diode pumped; and it facilitates the effects of detrimental quenching because of the high excitation density of a moderate gain. Its standard wavelength emission is of 1064 nm http://www.cheapnbajerseyshawks.com/Marco-Belinelli-Jersey/ , yet it can generate anything from 266, 355 or 532 nm by quadrupling, tripling or doubling the frequency. Specialists in the field really know how to joggle with the numerous components and wavelengths of these yttrium aluminum garnet lasers for optimum benefits. Nevertheless, what kind of benefits and practical utilities are we talking about? It turns out that anyone working in medicine, manufacturing, fluid dynamics http://www.cheapnbajerseyshawks.com/DeAndre-Bembry-Jersey/ , dentistry, military defense, cavity ring down spectroscopy, laser induced breakdown spectroscopy, laser pumping and even automotive may eventually need it. In medicine for example, they use it for anything from removing the toenail infection to cataract surgery and skin cancer treatments! In manufacturing http://www.cheapnbajerseyshawks.com/Mike-Muscala-Jersey/ , they engrave all sorts of materials with this laser, and in fluid dynamics they implement the laser components for flow visualization techniques. Dentists use YAG lasers for surgeries on soft tissues. At the opposite corner of utility’s spectrum, military and defense systems implement the technology in laser rangefinders and designators. As for the last and most surprising applicability, the one of automotive field, it regards a currently under research technique! Studied by some Japanese scientists, the project aims to set up an engine ignite fuel system based on YAG chips. Needless to say http://www.cheapnbajerseyshawks.com/Kent-Bazemore-Jersey/ , the tremendous benefits of this yttrium aluminum garnet technology are more than obvious. With tens if not hundreds of practical utilities, lasers make our world a better place. Knowing how and where they work will definitely help us at one point or another. One of the most effective and powerful ways to improve a child芒鈧劉s behavior is to make sure the child always assumes complete responsibility and ownership of his or her behavior. Often, parents inadvertently fail to have their child assume responsibility of misbehavior because they fail to recognize how their own behavior is contributing to the problem. This article highlights three ways that parents fail to have their child assume ownership of misbehavior and what parents can do to make sure that their child owns their own misbehavior.First of all, never excuse your child芒鈧劉s misbehavior. Often, parents excuse their child芒鈧劉s acting out behavior assuming that the misbehavior is contributed from sugar, red dye in foods http://www.cheapnbajerseyshawks.com/John-Collins-Jersey/ , ADHD (Attention Deficit Hyperactivity Disorder), and prior negative life experiences (parental divorce, death, bullying, abuse, neglect http://www.cheapnbajerseyshawks.com/Miles-Plumlee-Jersey/ , etc芒鈧?. There is no study that suggests a link between sugar and hyperactivity. There is no food allergy that causes children to lie, steal, talk back, etc芒鈧? Children diagnosed with ADHD need structure in their lives to help them manage their own behavior and to learn how to structure their own lives. Though negative life experiences can be sad and hurtful, it is crucial that parents do not give their child the message that it is okay to misbehave as a result of negative life experiences. It is important now more than ever that parents teach their children how to cope with negative life experiences in the absence of misbehavior or else their children will feel compelled to misbehave after each negative life experience.When parents excuse their child芒鈧劉s misbehavior, their child may develop a conditioned response. For instance http://www.cheapnbajerseyshawks.com/Taurean-Prince-Jersey/ , if a parent continuously blames sugar for their child芒鈧劉s misbehavior, their child may become conditioned into misbehaving every time he or she consumes sugar. The child is not misbehaving because of the effect of sugar in his or her body but because they were taught that misbehavior follows after the consumption of sugar.The same holds true for children diagnosed with ADHD. When parents tell their child that the ADHD is causing the misbehavior, the child becomes conditioned into believing that he or she is no longer responsible for their misbehavior because the ADHD is making them misbehave. In addition, when parents tell their child that he or she should be on ADHD medication or their medication needs to be increased to decrease misbehavior, there is a good chance that their child may become conditioned into believing that he or she is not responsible for their misbehavior until they begin taking AD. |
