...The theme of oppression is constant throughout both The Handmaid’s Tale and The Crucible. Both show how religion can be twisted into a form of control in society and they show the huge detrimental and devastating effects this control can have. Arthur Miller’s The Crucible shows the horror and appalling nature of the Salem witch trials of 1692, but beneath this surface it shows the parallels to aspects in Miller’s own life at this period, with the idea of McCarthyism going out of control in America. McCarthyism was a result of the second red scare in America in the late 1940´s/1950’s. It was a fear driven movement that swept across the United States where the threat of a Communist world revolution seemed like a very real threat. In response to this branches of the government set up organisations such as HUAC (The House Un-American Activities Committee) to help fight Communism from infiltrating the state. Unfortunately in the end it simply led to a ´witch hunt´ in which people were brought to trial and accused of being communist, Miller amongst them. HUAC and McCarthyism were simply examples of how when those in power feel threatened they will do anything to maintain their position which is what Miller set out to show in The Crucible. In The Handmaid’s Tale, Atwood took a different approach, with a dystopian text which shows a world in which women are heavily oppressed and religion is used as a tool to brainwash and control the population. Atwood has made a point of showing how...

...weigh out the salt, graduated flask for water, furnace, crucibles, sand, tongs, safety glasses and gloves. Starting materials: Epsom salts, water, 50% Aluminum - 50% Copper alloy (previously alloyed). Safety: Whenever you are dealing with hot liquids, there is the potential for burns and spills. Protect yourself from the possible risks, especially around the hot metal. Make sure you know where any potential spillage will go and place something in the way to protect yourself. In part ‘B’ be especially careful of the hot metal. Remember, it will still be very hot, even when it has changed back into a solid. Procedure: Part A: A supersaturated solution of salt will separate out into crystals on cooling. The size of the crystals is a function of the rate of cooling, the amount of impurities present and the degree of supersaturation (concentration of salt present in the solution). 1. Dissolve 25 grams of Epsom salts in 25 ml of water. Heat the water until all the salt dissolves, but keep the water below the boiling point. If all the salt will not dissolve, add water in small quantities until it does. Pour some of the solution onto a clean glass plate so as to form a thin film and watch it solidify. If it solidifies too rapidly, return it to your beaker and add more salt. Again, keep track of how much additional salt is added. When you achieve the proper mixture you should be able to observe the crystals start to form at the edge and slowly “grow” toward the center. 2....

...Maddison Weir Year 8 Science Practical Investigation: Making a Compound Introduction: A chemical change is any change that results in the combining of chemical substances to form new ones. Chemical changes can be detected by seeing a change in the colour, smelling a gas, seeing bubbles (effervescence), seeing a new solid form in a clear solution or seeing the energy being produced or absorbed in the form of heat or light. A physical change is the opposite of this. It is a change that does not result in the forming of a new substance. Two examples of chemical changes in real life include dying hair and digestion. In digestion the gastric acid in the stomach breaks down the food by using enzymes. Aim: To make a compound from the elements of...

...WATER OF HYDRATION Experiment No. 5 I. Objectives 1. To be able to identify and know the different properties of hydrates. 2. To observe and test the reversibility of hydration reaction. 3. To test and compare substance for efflorescence and deliquescence. 4. To determine the percent water in a hydrate. II. Results and Discussions According to Hamak, Hydrates are ionic compounds (crystalline salts) that are bonded to water molecules thus having a definite amount of it as part of their structures. This “water of hydration” is released as vapor when the hydrate is heated in which it loses water and become dehydrated (anhydrous). The remaining solid is known as the anhydrous salt. The general reaction for heating a hydrate is: A. Identification of Hydrates Compounds of Nickel Chloride (NiCl2), Potassium Chloride (KCl), Sodium Tetraborate or Borax (Na2B4O7·10H2O), Sucrose (C12H22O11), Potassium dichromate (K2Cr2O7) and Barium Chloride (BaCl2) each in about 0.5 grams were heated on a Bunsen flame and their behavior was then observed specifically determining whether one is a hydrate. Refer to TABLE 1. Fig.1. Unheated Compounds TABLE 1. Summary and analysis of the results pertaining to the tested compounds ...

...Canterbury Boys’ High School English 2014/15 Advanced Course The following information gives an outline of the Year 12 Advanced English Program for the HSC tested in 2015. The syllabus states that: The aim of Senior English is to enable students to understand, use, enjoy and value the English language in its various textual forms and to become thoughtful, imaginative and effective communicators in a diverse and changing society. The study of English involves exploring, responding to and composing texts • in and for a range of personal, social, historical, cultural and workplace contexts • using a variety of language modes, forms, features and structures. Meaning is achieved through responding and composing, which are typically interdependent and ongoing processes. In Year 12 time is allocated to certain issues and texts based on the time needed to cover the Board of Studies’ requirements for the fulfilment of the English outcomes. This program is based on the premise that: • students are required to experience literature in a variety of modes (short story, novel, poetry, non-fiction, film and drama) • there should be a continuing study of non-literary material (print and non-print, multi-media) • students should be encouraged to develop reading interests outside the classroom • there will be a continuing emphasis on oral English in class discussions, small group discussions, debating, public speaking, interviewing, dramatic reconstructions ...

...Solidification and crystalline imperfections: When molten alloys are cast, solidification starts at the walls of the mold as it is being cooled. The solidification of the alloy takes place not at a specific temperature but over a range of temperatures. While the alloy in the this range, it has a pasty form that consist of solid, tree-like structures called dendrites (meaning tree-like) and metal. The formation of Stable Nuclei in Liquid Metals: The two main mechanism by which the nucleation of solid particles in liquid metal occurs are homogeneous nucleation and heterogeneous nucleation. Homogeneous Nucleation in a liquid melt occurs when the metal itself provides the atoms needed to form nuclei. When a pre liquid metal is cooled below its equilibrium freezing temperature to a sufficient degree, many homogeneous nuclei are created by slow-moving atoms bonding together. For a nucleus to be stable so that it can grow into a crystal, it must reach a critical size. A cluster of atoms bonded together that is less than a critical size is called an embryo and one that is larger than the critical size is called a nucleus. Embryos: Small particles of a new phase formed by a phase (i. e. solidification) that are not of critical size and that can resolve. Nucle: Small particles of a new phase formed by a phase change (e . i . solidification) that can grow until the phase change is complete. Homogeneous Nucleation: The formation of small regions of a...

...COMMON LABORATORY TECHNIQUES AND PRACTICES Cleaning Glassware A common laboratory requirement is clean glassware. If clean, the walls will retain an unbroken film of water, not droplets. This can usually be achieved most simply and safely by scrubbing the wet walls with some common commercial scouring powder and an appropriate brush, followed by rinsing with tap water and finally with distilled water. Never use scouring powder on glassware which is inaccessible to scrubbing such as the inside of a transfer pipet. For this type of glassware use a liquid detergent in place of the scouring powder. Occasionally, specific chemical deposits are completely unaffected by these general cleaning methods, but if the chemical nature of the deposit is known, a specific reagent may be selected for cleaning; ask your instructor for advice in this circumstance. Drying Operations Glassware must frequently be dry as well as clean. This is best done by putting the glassware into a drying oven, preferably one with circulating air that will quickly remove the water vapor. Hot glassware with parallel sides, such as beakers and bottles, is most conveniently handled with beaker tongs as shown in Fig. 2. It is unwise to dry Pyrex and Kimax equipment by direct heating with a Bunsen burner; it is usually fatal (to the glassware) to treat soft glass equipment this way. Alternatives to the drying oven are wiping with clean toweling (but cloth and paper lint are often a problem)...

...2007:224 CIV M ASTER’S TH E SI S Study of the reactions between iron ore slag and refractories Julien Zimmermann MSc PrograMMeS in engineering Materials Technology (eeigM) Luleå University of Technology Department of Applied Physics and Mechanical Engineering Division of Material Mechanics 2007:224 CIV • ISSN: 1402 - 1617 • ISRN: LTU - EX - - 07/224 - - SE Summary: For the fabrication of iron ore pellets at LKAB (Luossavaara-Kiirunavaara AB), one of the methods used is to sinter the pellets in a rotary kiln. This Kiln has a drift temperature of 1250°C in average. During this process a coating, causing the wear of the refractories materials, is formed, inducing expensive maintenance periods. The aim of this work is to find the reaction that takes place between the Slag and the bricks, in order to find the parameters that have to be changed to improve the bricks lifetime in the kiln. The use of bricks with higher alumina content is one of the solutions, but it is expensive. The influence of Alkalis and especially Na2O has been studied before in inert atmosphere. In this work it will be studied in air as well as the influence of the alumina content of the brick. Experiments were performed in air atmosphere, using powder samples that have been compressed into pellets. The devices used to characterize the reaction and the product of the reaction were: Kanthal furnace, X-ray diffraction (XRD), dilatometer, differential scanning calorimetry and thermogravimetry (DSC/TG)...

...our ancestors, the Cro-Magnon, ornamented their bodies with lavish strings of beads made from ivory, seashells, and gemstones (Cook). As is the custom today, the use of jewelry was determined by fashion and reflected one's rank in society. Malachite is cut into cabochons or slabs to be used in rings, necklaces, brooches, and in art objects (galleries.com). Though not a precious stone, its vibrant colour is highly prized. Possibly the earliest order of copper, malachite is believed to have been mined in a Sinai and eastern deserts of ancient Egypt from was early as 300BCE. Single crystal are uncommon; when found, they are short to long prism. Malachite is usually found as botryoidal or encrusting masses, often with a radiating fibrous structure and banded in various shades of green. The beautiful green crystal has been used since ancient times in inlay work and in carvings of churches and cathedrals as it is found in huge boulders (Bonewitz pg 125). It was also used as a pigment for paint during the 15th century in Egyptian tomb paintings and much later in European art. The Victorians were also great admirers of opaque jewelry stones, and malachite was chosen to be one of their favorites, sometimes choosing it to set in gold. It also occurs as delicate fibrous aggregates and as concentrically banded stalactites (Bonewitz pg 125). Malachite occurs in the altered zones of copper deposits, where it is usually accompanied by lesser amounts of azurite. It is primarily valued as an...
