...time period The Devonian time period began 416 million years ago and ended 354 million years ago. Ranging about 62 million years. Devonian is in between are Carboniferous and Silurian time periods. “Its base is characterized by Monograptus uniformia a graptolite, and its top by Gattendorfia an ammonoid cephalopd.” (Mueller, Rey 2007). Mueller, P., & Rey, P. (2007, January 1). Introduction. Retrieved April 24, 2015, from http://www.geosci.usyd.edu.au/users/prey/FieldTrips/Yass04/Devonian.html Tectonics and climate Many changes had occurred in the world during the period of Devonian. In the beginning of the time a large areas of North America, Europe, South America, and Australia were covered by seas. During this period, the worlds land was collected in two supercontinents Gondwana and Euramerica. During the time period there was other changes that occurred. “The continents of North America and Europe collided, resulting in massive granite intrusions and the raising of the Appalachian Mountains of eastern North America. Vigorous erosion of these newly uplifted mountains yielded great volumes of sediment, which were deposited in vast lowlands and shallow seas nearby.” (Speer 1998). At the end of the period a mass extinction occurred. Its not clear what caused the mass extinction, but there are some hypotheses that may have caused it. Glaciation and the lowering of the global sea level may have triggered, changing in the atmospheric carbon dioxide, meteorite...

...Besides that, Philip Morris has use ammonia in the manufacturing of cigarette for over 50 years. The using of ammonia in cigarette is with few purposes such as to highlight certain flavors and to expand the volume of tobacco. The analysis of the smoke shows that cigarettes from the Eastern Mediterranean, Western Pacific and Southeast Asia are containing higher CO smoke, and tar, nicotine than brands from the American, European or African surveyed. The purpose of the ammonia in cigarettes is to affect the smoker so smokers are more addicts to nicotine. After the cigarette industry’s widespread Philip Morris’s company the use of ammonia technology, Philip Morris’s company was responded to a New York Times. A letter from Philip Morris’s director of public relation relations to York Times in 24 February, 1988 say that the using of ammonia in manufacturing cigarette will not increase the amount of nicotine to the smoker’s lung and brain. But however, although the using of ammonia does not increase the amount of nicotine to the lung and brain, but the chemical additives in the cigarette is to make smoker more addicted to nicotine. Philip Morris shouldn’t hiding the facts and manipulate the truth. Hosnety in business may good relationship with company. Nowadays, illness related to...

...Society as we know it today has grown from a number of complexed changes and events throughout history. The aim of this essay is to explore and outline a number of key differences from the 1500-1800 time period to today’s modern world, a summary of Blainey’s (2001) work will help give an idea of how life was in that earlier time period and allows us to reference it against what we know as today. Particular differences will be outlined between the two time lines with focus on war, the roles of animals and work structure. These differences will highlight how society has changed from a localized unit to a global unit. Society on a global scale was mostly Agrarian in structure whilst some nomadic style hunter gathers or pastorals groups (Blainey (2001, p.410) still existed in the early 1500’s-1800’s. Life revolved around food, the production of food was what made up day to day life, the average house hold didn’t have enough land to produce what was needed and many people worked at neighbouring farms and meals themselves were used as partial payment. Food was almost the be all and end all it determined wealth, stature and even if and when young single women could marry, Blainey (2001, p.412) explains that if a harvest was plentiful the woman may marry however if the harvest was lean the wedding would be postponed. Work on the farm was predomitdly carried out by the woman and elder children, duties such as fetching fire wood, collecting water from the well, spinning yarn, cooking...

...The Classical Period The Classical Art Period consisted of ancient Greek and Roman art and fell between the years 900 BC and 31 BC. During the Classical Period, Athens and Sparta were dominant cities in the Greek region. These cities were suspicious of one another, but managed to live peacefully together until the 5th century, BC. Cultural and political differences between the two cities caused a rivalry to form. The rivalry was eventually quelled after a brutal war which ultimately ended in the demise of both cities and the rise of Macedonia as the dominant power in the region. Eventually, the social structure in the Classical Period became somewhat of a democracy and an open society which we have emulated in the United States (“History of Greece: Classical Greece”, 2014). Many other wars occurred over the course of the Classical Period, and this culture of war contributed to the realism of the art of the time. The brutality of war and the effects it had on Greek society inspired artists to focus on man, rational thinking, and logic (“History of Greece: Classical Greece”, 2014). Greek artists in the 5th century, BC began to realistically imitate humans and animals through art (Boardman, 2012). These Greek artists gained a better understanding of anatomy and the human body’s mechanics, giving them the ability to realistically render the human form in multiple positions without appearing awkward. Logic was valued over emotion in sculptures. This means that facial expressions...

...performing the Simple Harmonic Motion Lab, our goal was to determine the period of motion for objects performing simple harmonic motion. We did five trials of measuring the time it took a pendulum to make 30 complete oscillations. We divided that time by 30 to get the period and then took the average of all 5 trials, getting an average period of 1.88 seconds. To compare our results, and see if they were correct, we used the given equation for the period of motion that includes the length of the pendulum to calculate the period for the same pendulum, resulting in 1.87 seconds, which agreed with our earlier results. This shows that period of oscillations can be determined by length and gravitational acceleration, and doesn’t depend on mass. In our other activity, we measured the period of an oscillating mass connected to a spring. We had a hanging spring, and hung mass to the bottom of it, each time measuring the change in length of the spring from the time before. To find the spring constant, we used the masses added to calculate each of their elastic forces, by multiplying each by gravitational acceleration, then plotting them with their corresponding spring deformation, and the slope of that graph was the spring constant, k, which was 8.22 N/m. Using this value, we calculated the period of motion for the mass of 0.1 kg using a different given equation than the one before, obtaining a period of 0.69 seconds. To verify our results, we used the VideoCom to graph the...

...The Neoclassical art period occurred in the 18th century Age of Enlightment and has been defined to have been between the years of 1780 CE and 1820 CE. This art period started when Pompeii was accidentally rediscovered in the 1700’s after Mount Vesuvius erupted, covering all the occupants. Europeans were fascinated with the frozen city and this revitalized the interest in the classical art of Rome and Greece. Neoclassical art techniques used light and dark colors to contrast, simulating the Baroque art time period. The artists from the Neoclassical period eliminated the heavy use of vibrant colors and busy compositions. The Neoclassical artists focused on techniques more uniform by using formulas and perspectives that were more exact. The subjects in many of the paintings from this time period looked shiny or glossy due to the artists attempting to hide their brushstrokes to make their artwork simulate the polished look of a marble sculpture. During this time period the American colonies claimed independence from Great Britain and the French Revolution broke out in Paris. The 1700’s marks the industrial revolution in Britain as well. This time period is referred to as the Age of Reason. It was a more stable and a traditional time and there seemed to be a general respect for authority. The Romanticism time period and has been defined to have been between the years of 1800 CE and 1850 CE. Romantic artists wanted to focus on emotional experiences instead of looking...

...different examples that are not just buildings, or objects, but as a reflection upon the thoughts and ideas of the time period in history. In this essay I will be discussing the dramatic impact that architecture has had on the major civilizations throughout time by being able to display them in their works, which not only was a clear representation of the time but as well helped mold and solidify the society’s thoughts through expression. By taking examples from ancient to modern times I will examine how the architecture of these eras clearly displays the thoughts and ideas of the culture in which it was built upon and as well the society in which it is placed. As well I will be examining how several major key architects played a dynamic role in these critical showcases that represented their time. I will be taking architectural examples from; the ancient Egyptian time period, the gothic and medieval time period, the renaissance & pre-modern period and the now contemporary period. Each one of these unique periods of time in architectural design were clear representation of the dynamic time period in our history. Here, looking back at these time periods we can see the most incredible works in architectural design that still to this day help us understand the culture at the time. As well I will be using several renowned architects throughout these time periods who were able to portray the culture, and society in their designs. These architects include, Michelangelo, Filippo...

...While in practice this is a rather daunting task that requires the consideration of thousands of items and prices, in theory computing the CPI is simple. CONSTRUCTING THE CPI: The CPI is computed through a four-step process. 1. The fixed basket of goods and services is defined. This requires figuring out where the typical consumer spends his or her money. The Bureau of Labor Statistics surveys consumers to gather this information. 2. The prices for every item in the fixed basket are found. Since the same basket of goods and services is used across a number of time periods to determine changes in the CPI, the price for every item in the fixed basket must be found for every point in time. 3. The cost of the fixed basket of goods and services must be calculated for each time period. Like computing GDP, the cost of the fixed basket of goods and services is found by multiplying the quantity of each item times its price. 4. A base year is chosen and the index is computed. The price of the fixed basket of goods and services for each comparison year is then divided by the price of the fixed basket of goods in the base year. The result is multiplied by 100 to give the relative level of the cost of living between...

...The Renaissance was a period of time from the 14th to the 17th century. It was considered a time of rebirth. The reason it was considered as the rebirth was because it introduced many new artists/inventors. The renaissance period was the most eventful time period in european history. It started in Italy and spread throughout europe, making it the beginning of the early modern age. It wasn't just a time period of art. It was considered to be a beginning of a whole new future. The inventors during this period, presented bits and pieces of ideas for what people have today. The interesting fact about the whole renaissance period is that most of the artist had an extraordinary understanding of future inventions with little or no previous knowledge of modern technology and how it worked....

...CASE STUDY FIN 501- THE TIME VALUE OF MONEY AND FINANCIAL STATEMENT ANALYSIS DR. JOHN HALSTEAD April 21, 2015 In this case study, I will work through a variety of time value money problems to grasp the concept of how to calculate the present and future value of a lump sum and the present and future value of an annuity. I will also learn how to calculate the present value of a perpetuity. This is important, because this enables me to learn how to determine the value of a typical corporate bond. Present Value of a lump sum, is the value of an expected income stream determined as of the date of valuation. The present value is always less than or equal to the future value because money has interest-earning potential, a characteristic referred to as the time value of money 1. a. PV=$100,000*11.0520=$94,911.41 If you were to receive $100,000.00 in 5 time periods from now, that $100,000 would be worth only $94,911.41 today. If you were to invest the $94,911.41 at a rate of .05% today then you would have $100,000 at the end of 5 time periods. So, if I had a choice between taking an amount higher than the $94,911.41 today as oppose to taking the $100,000 at the end of 5 time periods then I would take the money today. By doing so, I would be able to invest the higher amount at .05% for 5 equal time periods, which would end up being more that the 100,000. b. PV=$200,000*[1/(1.10)10]=$179,274.47 If you were to receive $200,000.00 in 10 time periods from now, that $200,000.00...
