...pre-classical economics which was from the 1500s till 1776). And in the later era we had 2 schools of economics, the Mercantilist and the Physicrats. Mercantilism was spread all over Europe and mean while physiocracy was a French school of economic thought which was in the period of time from 1750-1789. These two schools had different ways of thinking when it came to various things such as, wealth and growth, consumption and wages, trade, and money. The definition of wealth and money for the mercantilists was that the primary duty of the state is to enhance and maintain both national wealth and national power in order to defend the country and National Wealth consists solely or primarily in its supply of precious metals such as gold and silver. And the state or the government used to earn all this wealth by trade. Where the government encouraged exports and discouraged imports so that gold would be in the country which meant to them that they had more power since they are richer, and this will lead to the growth of the country. Whereas the physiocrats had a different idea on wealth and growth which was that wealth is in agricultural production and that growth is acquired when they had more crops which meant more production, and this will lead to a sustenance economy where the country consumes what it produces. Consumption and wages in the times of...

...Plain Sterling Silver Rings Sterling Silver is a very popular silver alloy. Sterling silver is nothing but pure silver alloyed with harder metals so as to increase its strength and durability. This is done because pure silver, though a precious and highly reflective metal with bright white shine, is prone to scratching as it is soft and very malleable. Sterling silver usually contains about ninety two and half percent of silver and is combined with other metals. The other metal usually combined in seven and half percent quantities is copper. The minimum millesimal fineness of sterling silver as per the sterling silver standard is 925. Other metals that can replace copper in sterling silver are platinum, zinc, germanium and even additives like boron and silicon. However, copper greatly increases the strength of the silver while keeping the beautiful colour and shine intact. Also, the small...

... Lord Of The Flies Island The last thing I remembered was smoke. We had been engaged with an enemy fighter when their was a loud bang and a bright flash. The cabin filled with smoke almost instantly and I felt as if my lungs were filling with water. Every breath felt like i had a heavy weight on my chest. I felt myself getting dizzy, like the whole plain was spinning out of control. I felt myself fall to the ground as I fought for air and my eyesight started going blurry till it faded into nothing but blackness. The smell of sea salt was strong in the air. The faint sound of waves crashing against rocks rolled in and out from the distance. I felt grains of sand, that felt like coals against my body and the cool breeze against my face. The bright light shined off the sand blinding my eyes as i opened them. I was on a small section of beach, that abruptly bleed into a dark and dense jungle. I looked up to the palm trees, like giant crow's feet, sway side to side through the wind. As i moved I felt sharp pain in my back, I looked to see a large bruise forming from where I must have hit the water when falling out of the plain. I glanced around at the beach, there was a small pool of water farther to the side of me and what looked like a small platform at the end of the beach made from sticks and mud. I pulled myself off the burning sand, and headed towards the dense undergrowth, the deeper I went into the vast jungle the more moist and heavy the air became. After walking for...

...The following is a summary of the video “Gilbane Gold,” which is a fictional case study in ethics. The video is presented by the National Society of Professional Engineers (NSPE). Z-Corp is an electronics manufacturing company in the heart of a farming town known as Gilbane. Several years previous, Gilbane had attracted Z-Corp to town by offering significant tax breaks, knowing that Z corporation would provide many jobs and boost the local economy. At the time, Z-Corp informed Gilbane that part of its manufacturing process involved the use of the heavy metals lead and arsenic, and that it would be discharging a certain amount of these into the sewer system. Gilbane was concerned about this discharge, because the town processes sewer sludge into a very profitable fertilizer product known as Gilbane Gold. The town council decided that a small amount of lead and arsenic would be tolerable, but to be safe, they put severe limits on the concentration of metals that Z-Corp would be allowed to discharge. The limits that the town council set were ten times smaller than those allowed by federal law, but Z-Corp agreed to abide by them. David Jackson is an environmental engineer at Z-Corp. He suspects that for the last few months, the company has been discharging more lead and arsenic than the law allows. The city is testing the waste water, but Jackson knows that their test is not very sensitive, and therefore they are probably not aware of the potential violation. Apparently...

...changes have aroused within younger generation. In today’s society, everything relies on technology and electronics, that it has now become a necessity rather than a recreational leisure item. With electronic devices or products, we only see the physical part of electronics but there are many chemicals, substances, and numerous parts within a simple device that are severely dangerous if consumed by any living organism. Many of the toxic substances that get released were improperly treated, stored, transported, or disposed of can be derived from the wiring, circuit boards, smaller electronic parts such as chips, monitors, and so forth. In addition, many of these electronic parts release severely dangerous chemicals such as; lead, mercury, zinc, silver, chromium, etc. There are many factors in which hazardous waste can affect us such as the following: - A large amount being released at once - Toxicity - Level of exposure/contact - Who particularly is exposed - Concentration/dose of exposure - How exposure is initiated - Time period of exposure For humans as well as animals and plants, there can be exposure through; inhalation, ingestion, or dermal exposure. Inhalation can be breathing dangerous chemicals in the form of vapors, or even from the contaminated water while drinking water from the tap or even as simple as showering. Furthermore, ingestion can take place through what we eat and whether or not it is contaminated itself such as; fish, fruits, veggies, and any other...

... Name: Khalid Unit 51: Electrical Technology Assignment 2 Teacher: Abdul khares P5, p6, p7 P5 Properties and typical application of a solid electrical conductor Copper Introduction: There are many good solid electrical conductors. Namely one main good solid electrical conductor is copper. As a technician (referring to the scenario given) I advise the use of copper as a solid electrical conductor and the reason will be explained below. Copper comes with many important properties conductivity, tensile strength and resistivity. The Cu represents copper in the periodic table and the atomic number which copper has Is 29. Applications of copper Applications of copper: nowadays copper is heavily used in pipes this is because copper is ductile meaning you can shape it however you want and it won’t snap easily. Also copper is used in generating electricity in places such as power stations as it is a good electrical conductor. Copper is also used in other things like building construction, consumer and general products etc. Properties of copper: Resistivity:’ Resistivity is the resistance across two opposite faces of a cubic metre of material’. What resistivity tells you is how resistive a material is. The symbol that is used to represent resistivity is p and the units that are in ohm meters. Copper has a very low resistivity the value of the resistivity of is. It is slightly this is because there is nothing next to copper in the resistance of...
