TECHNICAL ENGLISH – 2015 HOMEWORK 4 - REVIEW EXERCISES ACTIVITIES: 1. Practice reading the sentences orally. 2. Identify the nouns and their modifiers and write what you understand. Do it as shown in the example: The decline in (coal) sales. (Sales of coal) 1. New technology for deposit and substrate property measurements is needed, especially sensors to measure deposit thickness and techniques to measure residual stresses in thick deposits. 2. Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield. 3. A coatings properties database of materials characterization, mechanical properties, and statistical analysis needs to be established. 4. Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. 5 Mechanical testing and finite element analysis provide data that we evaluate in such terms as strength, toughness, etc. 6. The systematic characterization and solubility testing of precipitated compounds has allowed the most insoluble arsenic compounds to be identified. 7.

Our company provides computer model generation of isothermal and non-isothermal seven component phase diagrams as a function of possible fluxes compositions. 9. The equilibrium interfacial energy between a liquid iron alloy and a liquid slag is a key physical parameter in the design of steel-refining processes as high interfacial energies are desired to avoid emulsification of slag in steel and the creation of casting defects.

TECHNICAL ENGLISH 2015 HOMEWORK 4 - REVIEW EXERCISESACTIVITIES: 1. Practice reading the sentences orally.
2. Identify the nouns and their modifiers and write what you understand. Do it as shown in the example: The decline in (coal) sales. (Sales of coal) 1. New technology for deposit and substrate property measurements is needed, especially sensors to measure deposit thickness and techniques to measure residual stresses in thick deposits. 2. Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.3. A coatings properties database of materials characterization, mechanical properties, and statistical analysis needs to be established.
4. Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity.
5 Mechanical testing and finite element analysis provide data that we evaluate in such terms as strength, toughness, etc.
6. The systematic characterization and solubility testing of precipitated compounds has allowed the most insoluble arsenic compounds to be identified.
7. The mining industry has conventionally exploited those requiring simple metallurgical processing and has left the more refractory and metallurgically complex ores for future generations.
8. Our company provides computer model generation of isothermal and non-isothermal seven component phase diagrams as a function of possible fluxes compositions.9. The equilibrium interfacial energy between a liquid iron alloy and a liquid slag is a key physical parameter in the design of steel-refining processes as high interfacial energies are desired to avoid emulsification of slag in steel and the creation of casting defects.Activity: Read, underline the structural phrases and, then, write equivalent expressions as shown in the example:
Example: Wet cleaning is preferred to dry cleaning because of the excessive wear. (owing to) 1. Poisonous or irritant gases as well as particles emitted by these stacks posed serious danger to the vegetation and animal life.2. As the solids accumulate, a dump covering many acres is formed.
3. A polluting process has been either modified to decrease emissions, or replaced by another that is less polluting even if at a higher cost.
4. In addition, whole body melting of starting materials is required for alloying, thus imposing unwelcome chemical, thermal, and containment constraints on manufacturing.
5. Efforts are underway to eliminate, reduce and recirculate the liquid wastes so as to minimize their impact on the environment. 6. This is often practical because of the great reduction in bulk during the smelting operations.7. The workshop participants expressed several needs and concerns regarding the use of sensors and process measurement technology.8. The biggest disadvantage of this system is the slower cycle time due to the need to transfer the molten metal from the furnace to cold-chamber machine.
9. As a result, hydrometallurgists should lend their expertise in assessing the risks of metals.
10. However, hydroelectric power plants are not available, then, thermal plants are used.
11. Additionally, there was another category identified of potentially hazardous wastes.
12, Since conventional precipitation-settling technology is not satisfactory, the mining industry will have to deal with new decontamination processes.
