occupy octahedral sites (b). Which type of interstitial site will the ions occupy? Why? Since this ratio is between 0.414 and 0.732‚ the ions will also occupy octahedral sites. (c). What fraction of the total tetrahedral sites will be occupied? No tetrahedral sites will be occupied. (d). What fraction of the total octahedral sites will be occupied? For every formula unit‚ there are three ions‚ and‚ therefore‚ three octahedral sites; since there is one ion in each of and‚ two-thirds of these

his leadership qualities he was admired for. Washington was able to achieve some of his goals because of the policies and beliefs he followed in his life. Fraction is the main factor for destroying nations. It makes people fight instead of developing their country. When George Washington was elected‚ he knew that fraction was a problem that should be solved immediately. He saw people fighting and blaming each other. Political parties were a result of these conflicts. Eventually‚ people

Introduction to Laplace Transforms for Engineers C.T.J. Dodson‚ School of Mathematics‚ Manchester University 1 What are Laplace Transforms‚ and Why? This is much easier to state than to motivate! We state the definition in two ways‚ first in words to explain it intuitively‚ then in symbols so that we can calculate transforms. Definition 1 Given f‚ a function of time‚ with value f (t) at time t‚ the Laplace transform of f is ˜ denoted f and it gives an average value of f taken over all

Preparation A Case Study in the Implementation Of Novel Technology: Teetered Bed Separators What is a teetered bed separator? Most people are familiar with elutriators‚ which permit the separation of particles on the basis of particle size. This is achieved simply by subjecting a slurry of a mixture of particles to an upward current of water in a vertical column. Under these circumstances‚ particles whose settling velocity is greater than the upward current report to the underflow

can be hydrolyzed into simpler carbohydrates by acids‚ various enzymes‚ or a combination of the two. The resulting fragments are known as dextrins. The extent of conversion is typically quantified by dextrose equivalent (DE)‚ which is roughly the fraction of the glycosidic bonds in starch that have been broken. These starch sugars are by far the most common starch based food ingredient and are used as sweetener in many drinks and foods. They include: Maltodextrin‚ a lightly hydrolyzed (DE 10–20)

Distillation of vodka Athena Bianca Mattus*‚ Rency Mae Silvestre‚ Maria Robelaine Tenefrancia‚ Shaira Mae Yu Department of Chemistry‚ College of Science *Corresponding author; e-mail: tinabianca_09@yahoo.com Abstract Through simple distillation‚ the percent ethanol and percent loss of 15 mL of vodka was computed. The calculations were supported by a flammability test. With the distillation process reaching 100oC‚ 6.0 mL of distillate was collected. The determination of ethanol from the distillate

Engineering Lettering Lettering is an essential element in both traditional drawing and CAD drawing. Graphic communication is often not enough to completely describe an object. Lettered text is often necessary to provide detailed specifications about the drawn object. And there are a number of formal rules that apply to the placement of lettering. Commercial Gothic‚ also called sans-serif Gothic‚ is the lettering style of most interest to engineers. It is plain and legible. While admittedly

give a scientifically sound explanation. For instance how would you calculate fi (the fraction of intelligent life forms)‚ how do you define intelligent? Is intelligent like you and I‚ is it like a bird or a rat‚ could it be a plant? There is no way to truly determine what counts and doesn’t count as intelligent life forms. There is too much gray area! Another element to the equation is fc‚ (the fraction of intelligent species that develop interstellar communication). How would we know which
