This however is relaxed often due to slight lowering of symmetry. One point to note is that in colours of transition metal complexes the strict d-d transition is formally quantum mechanically forbidden. He is the sort of chemist who looked at all sorts of high oxidation type metal complexes and has just published his 1250th paper One name springs to mind - "Kurt Dehnicke". Higher oxidation "Werner type" complexes were almost certainly studied in the early part of the 20th century and probably revisited later when spectroscopic methods became much more sophisticated in the 1960's and 1970's. This is largely because many of its compound undergo oxidative addition reactions which were of tremendous interest due to their similarity to Wilkinson's catalyst. Iridium has been extensively studied particularly low oxidation state iridium complexes such as Vaskas complex. Probably "IrCl4" is some complex compound, with Ir and Cl atoms in it at a ratio 1 : 4. There unfortunately is only little literature about this.Īlso, the "IrCl4" has net formula IrCl4, but it is not simply iridium (IV) chloride (according to many textbooks, that compound is of doubtfull existence). The colors are a mystery to me, I need more research and I'll try to find out more about that. It can be applied in thin layers or you can choose to create thicker textures that highlight the character of the finish. When an oxidizer is added in the presence of hydrochloric acid to this yellow solution, then it becomes dark red (like red wine, but a brighter color). When the solution is acidified and a reductor is added, then the solution turns yellow (color of iridium (III) ?). IrCl4 certainly is as intense as KMnO4 when it is dissolved in water and gives a dull purple color to the solution (not the bright purple of KMnO4). One thing I can say already, the number of colors, which can be made with solutions of iridium salts really is great and the colors are very intense. I ordered 3 grams of "IrCl4" and I will soon make a page about the different colors of solutions of Ir-salts. I do not have any experience with plutonium (my sample did not yet arrive ), but I do have experience with iridium salts. This mix of basic copper salts indeed is green with a somewhat blue hue (green/cyan). When copper rusts, then no copper oxide is formed, but a basic copper carbonate and/or a basic copper sulfate (depending on the precise nature of pollutants of the air).

There's a reason why every single one of us looks different. There is no definitive average men's ring size or average women's ring size to this question since everyone's finger size is different.Ī person's finger size will vary depending on a person's weight, sex, and genetics. Choosing the right width will also affect the look and comfort of your ring. But a ring size depends on so many different things. An average women’s ring size tends to be between size 6 and size 10. The average ring sizes for men tend to be between size 8 and size 14. In this article, we'll go over the basics of ring sizes and how you can size yourself up. The opposite is true for men, where they tend to have a wider band than their partners. Women tend to prefer a smaller width ring, leading to a shorter ring. The major differences are in the width of the ring. So what's the right way to go about it?Īnd if the average men's ring size is larger than a women's ring size, are men's ring sizes the same as women's ring sizes? Thankfully, men and women ring sizes are the exact same. Average men's ring sizes tend to be larger than a woman's ring size, but that doesn't mean getting a size too large is a good idea. It also doesn't help that there isn't a single answer when it comes to sizes. A size too tight will lead to an uncomfortable fit. Since you are unable to try on the rings in person, how will you know what size you need? A size larger than needed can lead to a loose ring that you can lose easily. The most important thing about online ring shopping is getting the right ring size. This effect can be demonstrated with the following simple setup.Īs seen, a laser is used as a source of light and a coin is placed before it to block its path. Interference occurs due to diffraction of light around the sides of the object, which causes the shadow to become fuzzy. This is apparent when you notice the fuzziness around the edges of the shadow. However light also displays the wave-like quality of diffraction. When light encounters an obstacle in its path, it tends to cause the formation of a shadow in the region behind the obstacle. Water waves and sound waves have the ability to travel around corners, obstacles and through openings, and light waves too are able to display this ability. This occurrence advocated its wave-like behavior because if light was just a stream of particles, how could it bend around the sharp boundaries of the slit and continue moving similar to a water wave? He used it to describe the phenomenon where a single beam of light, when passed through a narrow slit, was able to split into different directions creating an interference pattern. The term ‘diffraction’ was first coined in the year 1660, by Italian physicist Francesco Grimaldi. However, the discovery of diffraction of light proved that it had wave-like qualities as well. Many of light’s behavior and properties led to the conclusion that it must be a stream of particles. Diffractionįor many years, scientists had debated on whether light is a linear stream of particles or a wave.

If you choose to write your mathematical statements, here is a list of acceptable math symbols and operators. With the calculator, you can practice on how to find the roots of a quadratic equation simply by working the problem your own way and comparing the results with those of the calculator. This calculator not only gives you the answers but it helps you learn algebra too. Here are more examples to help you master the factoring equation method. This can make the equation easier to solve. Sometimes, a quadratic equation can be simplified by factoring, or expressing the equation as a product of separate terms. The calculator factors nicely with all the steps. Quadratic equations are formulas that can be written in the form Ax2 + Bx + C 0. Using this calculator enables you to factor a quadratic equation accurately and efficiently. Factoring quadratic equations means converting the given. You can factor polynomials of degree 2 in order to find its solution. Factorization of quadratic equations is the part of finding the roots of a quadratic equation. Move all nonzero terms to the left side of the equation, effectively setting the polynomial equal to 0. Step 3: Equate Each of the product to Zero Step 2: Choose best combination for Factoring, Then Factor And Simplify Explanation: To find the domain, find all areas of the number line where the fraction is defined. Step 1: Find j=-6 and k=1 Such That j*k=-6 And j+k=-5 Factor The Quadratic Equation : Example Question 3. The area of a rectangular garden is 30 square feet. can sometimes be factorised into two brackets in the form of ((x + a)(x + b)) where (a) and (b) can be any term, positive. Factoring a quadratic equation can be defined as the process of breaking the equation into the product of its factors. For example, 12x2 + 11x + 2 7 must first be changed to 12x2 + 11x + 5 0 by subtracting 7 from both sides. Factor theorem Factorization of Quadratic Equation by Splitting the Middle term Step 1: Consider the quadratic equation ax 2 + bx + c 0 Step 2: Now, find two numbers such that their product is equal to ac and sum equals to b. For example, 2x 2 is a quadratic expression as the power of x is 2. To illustrate how the factoring calculator works step by step, we use an example. When you use the Principle of Zero Products to solve a quadratic equation, you need to make sure that the equation is equal to zero. If we can take a quadratic equation, which is just a polynomial set equal to zero, and factor that polynomial, we can use the Zero Factor Theorem to solve it. Prepare yourself for factorising quadratic expressions by multiplying out the brackets. The actual quadratic equation is the expanded. Such an equation is formed when we set a quadratic. When there is a negative value as the radicand, we rewrite the radical using the imaginary unit and the solutions are non-real number.An algebra calculator that finds the roots to a quadratic equation of the form ax^2+ bx + c = 0 for x, where a \ne 0 through the factoring method.Īs the name suggests the method reduces a second degree polynomial ax^2+ bx + c = 0 into a product of simple first degree equations as illustrated in the following example:Īx^2+ bx + c = (x+h)(x+k)=0, where h, k are constants.įrom the above example, it is easy to solve for x, simply by equating either of the factors to zero. Quadratic equations can be factorised rapidly with this cool fast math trick. In order to factor a quadratic, you just need to find what you would multiply by in order to get the quadratic.

We are just beginning to unlock its potential and look forward to what’s ahead as we explore other opportunities with end users.” “Celanese is proud to bring its polymer expertise and technical know-how to help manufacture NEOLAST™ fibers for textiles and fabrics to meet the specific needs of our customers and other value chain partners. “Working with a leading global brand like Under Armour to elevate the performance and sustainability benefits of their products is just the first of many great things we hope to accomplish with this innovative NEOLAST™ technology,” said Tom Kelly, Senior Vice President, Engineered Materials at Celanese. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure. NEOLAST™ fibers will be produced using recyclable elastoester polymers, a critical first step for the industry to address the challenge of recycling blended fabrics containing elastane. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane. NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex.

This relates to the migration and expansion of the Celtic tribes (cf. during the pre-Roman and Roman Iron Age in Northern Europe.Īccording to Barry Cunliffe, this was “a time of immense social upheaval and readjustment.” (cf. Roughly, this results in a time frame of approximately 700 years, i.e. 38), and in the case of the Latin thesis at the time of intensive Germano-Roman contact, so not prior to the 1st century BC and probably only in the course of the first and early second centuries AD. 374), in the case of the North Etruscan theory at the “end of the second century BC” (cf. Whilst the location of the place of origin and the rough ethno-linguistic classification of the writers of the first runes are relatively easy to determine, depending on the preferred theory, another point in time for the creation of the runes must be assumed: In the case of Theo Vennemann’s Phoenician thesis, the earliest runes would’ve already been created “between about 525 and 201 BC.” (cf. Later on, after the separation of the Proto-language into several daughter-languages or dialects, distinguishable inscriptions in East and South/West Germanic languages were found as well (cf. The ethnicity of the people which employed the runes seems rather obvious as well, since the inscriptions in the Elder Futhark were primarily written in a language termed “Nordic-West Germanic Language Unit” or “Early Runic” and the speakers were therefore Germanic or at least able to speak this Proto-Germanic dialect. Historical Context in Ancient Germania and ScandinaviaĪs in regards to the place of origin of the runes it is generally assumed today that they originated somewhere in or around the Danish Isles, as this is where the oldest inscriptions have been found (cf. Then the theses described above and their arguments are put forward and criticized individually, and finally the current state of research is summarized and an outlook on future research opportunities is given to solve the problem of the origin of the runes.Īs a basis for this work, mainly scientific introductory books on runology, as well as essays in runological, historical and scriptural journals and specialist books were used. To begin with, I will briefly introduce the reader to the relevant historical context and mark out the time frame in which the Elder Futhark could have been created, whereupon I present an overview of the runes themselves. This particular theory is not necessarily more plausible than the Greek one, and it’s struggling with some of the same problems, such as centuries of virtually no archaeological proof between the proposed time of origin and actual archaeological finds, but it is able to answer many of the questions that the previously put forward theories could not. ibid.), I would instead like to include the Phoenician hypothesis, which has mainly been represented by Theo Vennemann in the recent past. Since the Greek thesis has lost many of its supporters to the Latin and North Etruscan variants (cf. Traditionally, a comparison has often been made between the Latin, North Etruscan and Greek thesis, mostly in this order from the most probable to the most improbable (cf. This article is to deal specifically with the origin of its oldest form, the so-called Elder Futhark, and to present, compare and criticize the arguments of two prominent and one rather controversial, yet intriguing, theory in regards to its origin in detail. The Runes are the oldest form of writing in Northern Europe (cf. Picture of the Icelandic Codex Regius, one of the “original” copies of the Poetic Edda. In contemporary historical research, however, no consensus in regards to their actual origin has been able to be established yet (cf. This shows that the people writing the runes themselves believed in a “divine origin” (ibid., p. Such was the creation of the runes, the mythical signs of the Vikings, according to their very own legends, documented in 13th century Iceland in form of the Elder or Poetic Edda, as Klaus Duewel and many others have noted before (cf.

In non-retail OS images, the Boot Manager next runs an offline crash dump boot application that allows the device to capture a snapshot of physical memory from the previous OS session. The Boot Manager first captures any reserved hardware button combinations that are pressed by the user. Only boot applications, which are launched by the Boot Manager, have access to the boot libraries. The Boot Manager launches boot applications sequentially, and each application exits back to the Boot Manager after finishing.īoot libraries are libraries of functions that extend upon existing UEFI functionality, and are designed to be used within the boot environment. The following steps describe this process in more detail:Īfter the UEFI environment launches the Boot Manager, the Boot Manager initializes boot libraries, reads the boot configuration database to determine which boot applications to run and in which order to run them.
