...Egyptian blue was the first synthetic pigment ever produced by man; it is considered a great technology development in the ancient Egypt, as it appeared in Egypt during the third millennium BC. [9] This pigment consists of the mineral cuprorivaite (CaCuSi4O10), a blue tabular crystal about 15–30 mm in length, residual silica (quartz and/or tridymite) and an amorphous silica-rich phase. This pigment was made by mixing calcium salt (carbonate, sulfate or hydroxide), a copper compound (oxide or malachite), sand (silica), and an alkali flux (sources of alkali could either have been natron from areas such as Wadi Natrun and El-Kab, or soda-rich plant ashes).[10] This mixture then is heated to produce a colored glass or frit and ground to a powder.[11] Synthesis of the pigment can be summarized as follows: a mixture of quartz, calcium salt, copper salt or copper carbonate (malachite)...

...Blu Ray Disc Abstract When speaking of innovation, technology certainly does not seem to be slowing down any time soon. A perfect example of this can be seen with audio and video disc-based technology. Throughout history, discs have evolved tremendously. This research paper discusses the newest type of disc-based technology better known as a Blu-ray disc. Blu-ray discs are a relatively new kind of disc that takes entertainment to a whole new level. Like with other innovative and new types of technology, the disc developed new ways in which society sees certain issues. Some of the main points discussed throughout the paper about the Blu-ray disc include its background as a new form of technology, its potential benefits, its production, and its future. The paper will also describe and emphasize on its social, legal, ethical, and security-related problems since its development and launch into the world. This paper explores the “format war” that was developed in the 2000s between the Blu-ray disc and Toshiba’s HD DVD disc, and the issues that were created as a result of these two different and incompatible disc formats. Relating to security, this paper discusses how piracy has been somewhat victorious, yet a failure at times, when dealing with illegally downloading films of this high-definition format. Also, the paper will discuss the legal aspects of the Blu-ray discs, as it relates to licensing and copyrights. Socially, this paper gives examples of ways in which the...

Evaluate the Dominant Economic Traits of the Tea Industry in Pakistan. 2. How Ray Ban is Using Music, Architecture and the Human Experience to Sell Sunglasses 3. Create IFAS & EFAS for Tapal Tea. March, 2015 Karachi, Pakistan IQRA UNIVERSITY INTRODUCTION Ray-Ban is a brand of sunglasses and eyeglasses founded in 1937 by American company Bausch & Lomb.[1] The brand is best known for their Wayfarer and Aviator styles of sunglasses. In 1999, Bausch & Lomb sold the brand to the Italian Luxottica Group for a reported $640 million.[2] HISTORY OF Ray-Ban The history of the Ray-Ban Aviator dates back to the 1930s, when new airplanes allowed people to fly higher and farther. Many US Army Air Service pilots were reporting that the glare from the sun was giving them headaches and altitude sickness. In 1929, US Army Air Corps Lieutenant General John MacCready asked Bausch & Lomb, a Rochester, New York-based medical equipment manufacturer, to create aviation sunglasses that would reduce the headaches and nausea experienced by pilots, which are caused by the intense blue and white hues of the sky,[3][4] a new kind of glasses were introduced. The prototype, created in 1936 and known as ‘Anti-Glare’, had plastic frames and green lenses that could cut out the glare without...

...copy of an entire feature film on a single five-inch disc, had been introduced in the spring of the year.” (History). Even with the number of titles limited (less than a thousand at the time), Hastings and Randolph thought the format had the potential to replace video tapes. This was also the same period that the much larger laser disk was coming on the scene. They took the risk that the DVD would out produce other formats and overcome to become the new standard in home video. The company opened on April 14, 1998, with 30 employees and 925 titles for rent. (History) The company initially worked under the business plan of renting and selling DVDs to customers; providing an alternative to the local video store. The case for NetFlix.com (note the upper case F) was that it could provide a customer the exact movie they wanted, at a low cost and without the hassle of going to a store that may not have it in stock. In 1999, sales of the videos were halted. Group Arnault invested $30 Million into the firm. (History) It was at this time that the subscription plan debuted. A...

...All of this is also part of the electromagnetic spectrum. Electromagnetic spectrum is range of wavelengths that electromagnetic radiation could extends.Red being the longest wave length then followed by orange, yellow , green , blue , indigo and violet which has the shortest wave length. In this case this means that Gamma rays had the longest wave length followed by x rays , ultraviolet , infrared, microwaves then the one with the shortest wavelength is radiowaves. This means that radio waves has the lowest frequency. The shorter the wave length the lower the frequency. Frequency is the amount of wavelengths that passes through a certain point. So using radio waves as an example since it has the shortest wave length so that means that it would be faster for a wavelength to travel, this is measured in...

...The Shape of the Earth The shape of planet Earth has fascinated scientists, philosophers and cultures throughout history. For thousands of years man has observed and studied the Earth. Through observations, spiritual beliefs and empirical findings, many theories developed regarding the shape of the Earth. How has our understanding of the shape of the Earth changed over time? • Most ancient cultures, such as the Sumerians, Babylonians, even Greece , until the 5th or 6th century B.C., believed that the Earth was flat. (Garwood, 2007, p. 16) • The Egyptians believed the universe was rectangular-shaped with four pillars that supported a flat ceiling. Egypt was in the center of a flat Earth which was surrounded by water. (Moore, 1968, p. 16) • Greek philosopher Pythagoras, populated the idea that the Earth must be a sphere back in the 6th century B.C. • Around 330 B.C. Aristotle accepted the spherical shape of the Earth, observing that the Earth casts a round shadow on the moon. • Sir Isaac Newton observed the shape of the Earth to be oblate spheroidal or oval shaped, not prolate spheroidal or spherical. (According to Choi, 2007) • Giovanni Cassini, who discovered four moons of Saturn and estimated the distance between the Earth and Sun to be 87 million miles, maintained that the Earth was flat at the equator. His theory stirred controversy, contradicting Newton’s and others who maintained that the Earth was flattened at the poles. (Burns, 2001, p. 55) What...

...Running Header: Asthma Paper on Asthma September 10, 2010 Abstract Chronic bronchitis is a preventable disease highly linked to smoking. Once a patient is diagnosed with chronic bronchitis through pulmonary function tests and other exams, it is not curable but there are medications that may help in alleviating symptoms. Chronic bronchitis patients are often referred to as “Blue bloater.” In chronic bronchitis, there is a marked increased in the proliferation of the goblet cells that results in excess mucous production. There is marked inflammation of bronchial mucosa due to infection or chemical inhalation. There is excessive mucus production occurring on most days for at least three consecutive months for two consecutive years. Some medications that are use in the treatment of chronic bronchitis are: adrenergic agents, anticholinergic agents, corticosteroids agents and antibiotics. Since there is no cure for chronic bronchitis at the present time, the prognosis is fair in regards to when the diagnosis is made. If detected early enough steps can be taken to prevent further damages to the lungs. Smoking cessation is a key factor in stopping the progression of the disease. Pulmonary rehabilitation including exercise training and education about the disease and the harmful effect of smoking is an essential component of chronic bronchitis therapy. Paper on Chronic Bronchitis Introduction Chronic Bronchitis belongs to a part of a larger group of diseases called...

...Elements of a good ending; A Complicated Kindness and Kite Runner While writing a novel the writer must emphasize on the basic elements of ending the storyline. Efficient ending of a story answers the reader’s expectation of the story’s question. A good ending seals the reader’s impression of all they have read in the story. Therefore a good ending is necessary in writers doing literature writing as they motivate a reader to enjoy reading. There are four main elements which guide a writer in creating a good story ending in a novel. Comparisons between two novels; a complicated Kindness and Kite runner ending will help establish a good example of each of the four elements discussed below. First a good ending should seek to address the main problem or the antagonist. The protagonist does not necessarily have to win every time in a story but the main issue and problem be addressed in a way with the major win or defeat on the protagonist part. A complicated Kindness Miriam Toew’s keeps on addressing Nomi who is the antagonist in the story towards the end of the novel Nomi is seen as an courageous girl gathering means to help re unite her family together. She does so by seeking to trace her mother and a sister who left their community. She oppressively resists the rebellious rules and cultures in her society. Another significant element is the tying of loose ends and provision of a closure .this element applies on enhancing the reader to get anticipated on the next series of the novel...

...at the bigger the force impacted on the body that it hit. This is why it would hurt when you catch a sliothar and your hand is completely stagnant. Some day to day examples of inertia are: • Being pushed back into your seat when an airplane takes off • Being jerked forward when your car suddenly stops • The “tablecloth trick” yanking a table cloth while the dishes remain in place. Electromagnetic spectrum The electromagnetic spectrum is a way of organising all electromagnetic waves according to frequency and wavelength. There are many frequencies such as Radio, Micro, Terahertz, Infrared, Visible, Ultraviolet, X-ray and Gamma. The frequency that is most important to human beings in the electromagnetic spectrum is light. The range that light can be seen is a narrow portion of the spectrum, from 0.4 microns (blue) to...

...Section 1: Claim: Observable factors that affect the composition of LEDs During our research of gallium arsenide phosphide (GaPxAs1-x), which is a semi-conducting material in the form of light emitting diodes, we observed how properties of the data collected directly correlated to the composition of the LED. The observed and measured properties we were able to notice and calculate during our research were wavelength, color, voltage, and temperature. Using a diffraction grating we first tested the different compositions for which color of light was emitted. Our data as can be seen in appendix 1, on pg. L93 table 1, shows that as the composition shifted from GaP0.40As0.60 to GaP1.00As0.00 the colors emitted, shifted from those associated with longer wavelengths to those of shorter wavelengths. (Red to green) We then set up a scanning spectrometer in order to measure the wavelengths, and as can be seen in our data in appendix 1, on pg. L94 table 2, as well as on the graph in appendix 2, we were able to measure the wavelength of each LED with varying composition. According to our data it can be said that greater bond length equals lower Eg, since lower Eg will result in longer wavelength. For example, GaP1.00As0.00 has the shortest wavelength and the shortest bond length, and as a result has the largest band gap energy. From the same data we can also conclude that greater bond strength equals greater Eg due to the fact that GaP1.00As0.00 has the highest bond strength. The reason...

...distribution and recording. Furthermore, the increased capacity accommodated more demanding data applications. At the same time, the DVD spec used the same form factor as the CD, allowing for seamless migration to the next generation format and offering full backwards compatibility Now, in the next millennium, High Definition video is demanding a new solution. History proved that a significant five to ten time increase in storage capacity and the ability to play previous generation formats are key elements for a new format to succeed. This new format has arrived with the advent of Blu-ray Disc, the only format that offers a considerable increase in storage capacity with its 25 to 50 GB data capacity. This allows for the next big application of optical media: the distribution and recording of High Definition video in the highest possible quality. In fact, no other proposed format can offer the data capacity of Blu-ray Disc, and no other format will allow for the same high video quality and interactive features to create the...
