How Much Gold Is in the Ocean

In 1872, British chemist Edward Sonstadt published a report declaring the existence of gold in seawater. Since then, Sonstadts discovery has inspired many, from well-intentioned scientists to con artists and swindlers, to find a way to extract it. Quantifying the Oceans Riches Numerous researchers have  sought to quantify the amount of gold in the ocean. The exact amount is difficult to pinpoint because gold exists in seawater  at very dilute concentrations (estimated to be on the order of parts per trillion, or one part gold per trillion parts water). A study published in Applied Geochemistry measured the concentration of gold in samples taken from the Pacific Ocean, and found that they were about 0.03 parts per trillion. Older studies reported a concentration of about 1 part per trillion for seawater, about 100 times more than other, more recent reports. Some of these discrepancies may be attributed to the presence of contamination in the samples collected as well as the limitations of technology, which in past studies may not have been sensitive enough to accurately detect the quantity of gold.   Calculating the Amount of Gold According to the National Ocean Service, there are about 333 million cubic miles of water in the ocean. One cubic mile is equivalent to 4.17 * 109 cubic meters. Using this conversion, we can determine that there are about 1.39 * 1018 cubic meters of ocean water. The density of water is 1000 kilograms per cubic meter, so there are 1.39 * 1021 kilograms of water in the ocean. If we assume that 1) the concentration of gold in the ocean is 1 part per trillion, 2) this concentration of gold holds for all ocean water, and 3) parts per trillion corresponds to mass, then we can calculate an approximate amount of gold in the ocean using the following method: One part per trillion corresponds to one trillionth of the whole, or 1/1012.Thus, to find out how much gold there is in the ocean, we must divide the amount of water in the ocean, 1.39 * 1021 kilograms as calculated above, by 1012.This calculation results in 1.39 * 109 kilograms of gold in the ocean.Using the conversion 1 kilogram 0.0011 tons, we reach the conclusion that there are  about 1.5 million tons of gold in the ocean (assuming a concentration of 1 part per trillion).If we apply the same calculation to the concentration of gold found in the more recent study,  0.03 parts per trillion, we reach the conclusion that there are 45 thousand tons of gold in the ocean. Measuring the Amount of Gold in Seawater Because gold is present in such low quantities and is included with many other components from the surrounding environment, samples taken from the ocean must be processed before they can be adequately analyzed. Preconcentration describes the process of concentrating the trace amounts of gold in a sample so that the resulting concentration lies in the optimal range for most analytical methods. Even with the most sensitive techniques, however, preconcentration may still yield more precise results. These methods include: Removing water through evaporation, or by freezing water and then sublimating the resulting ice. Removing water from seawater, however, leaves large quantities of salts like sodium and chlorine behind, which must be separated from the concentrate before further analysis.Solvent extraction, a technique in which multiple components in a sample are separated based on how soluble they are in different solvents, like water versus an organic solvent. For this, gold can be converted to a form that is more soluble in one of the solvents.Adsorption, a technique in which chemicals adhere to a surface like activated carbon. For this process, the surface can be chemically modified so that gold can selectively adhere to it.Precipitating the gold out of solution by reacting it with other compounds. This may require additional processing steps that remove other elements in the gold-containing solid. The gold can also be further separated from other elements or materials that may be present in the samples. Some methods for achieving separation are filtration and centrifugation. After the preconcentration and separation steps, the quantity of gold can be measured using techniques that are designed to measure very low concentrations, which include: Atomic absorption spectroscopy, which measures the amount of energy a sample absorbs at specific wavelengths. Each atom, including gold, absorbs energy at a very specific set of wavelengths. The measured energy can then be correlated to concentration by comparing the results to a known sample, or reference.Inductively coupled plasma mass spectrometry, a technique in which atoms are first converted to ions, and then sorted depending on their mass. The signals corresponding to these different ions can be correlated to concentration by correlating them to a known reference. Key Takeaways Gold exists in seawater, but at very dilute concentrations – estimated, in more recent times, to be on the order of parts per trillion. Because this concentration is so low, it is difficult to pinpoint exactly how much gold is in the ocean.Even if there is an abundance of gold in the ocean, the cost to extract the gold from the sea would most likely outweigh the value of the gold collected.Researchers have measured these small concentrations of gold with techniques that are capable of measuring very low concentrations.Measurements often require that the gold be preconcentrated in some way and separated from other components in a seawater sample, to minimize the effects of sample contamination and allow for more precise measurements.

Career Development Strategies

Question: Write an essay on Career Development Strategies. Answer: Bill Gates was an intelligent entrepreneur and always believed that one can achieve anything by applying his intelligence. From childhood, he was ambitious and competitive and he wanted to do something that no one has ever done. This characteristic of Bill Gates justifies Trait-Factor theory of career development. His vision was legendary and unique as he dreamed about a computer on every desk and Microsoft software on every operating system. He decided not to stop until he could achieve his goals. This goal setting quality of Bill Gates can be compared with the Krumboltz Social Learning Theory of Career Choice (Lyness Erkovan, 2016). Innovation was his primary tool and based on his innovative ideas and with the help of his childhood friend Allen, Bill Gates released a version of FORTRAN language for microcomputers in the year of 1977. On year later, Gates introduced a version of COBOL and emerged as a market leader. This innovative or artistic phenomenon of Bill Gates is similar to the Hollands Career Typology Theory where artistic quality is considered as a unique and important quality of ones personality (Lyness Erkovan, 2016). Throughout his career, Bill Gates was also known as risk bearer as he never hesitated before dropping out of Harvard to devote his all the energies to Microsoft. Even after starting the company in 1975, he never stopped learning new things. By understanding the need for the people and demand of the market, he kept making changes in his organization, plans and services (Conklin et al., 2013). Supers Life-Span Theory states that same as it believes that human change is continuous that depends on the experiences they face at various life stages. This theory is again relevant to Bill Gates career as he kept making changes and enhanced his approaches even when IBM pulled out of the contract for the operating system that was to be bundled with the IBM Clone PCs (Mitravich, 2015). Even after this huge loss, he stayed on and focused on crea ting better versions of Windows (Pryor Bright, 2012). Bill Gates not only devoted his life in upgrading information technology but also contributed largely in social prosperities. He along with his wife Melinda Gates established Bill Melinda Gates Foundation in the year of 2000 with an aim to enhance healthcare and reduce poverty. This social act of Bill can again be compared with Hollands Career Typology Theory. While discussing personal values, Bill Gates showed a great deal of creativity to bring change and variety in the world of information technology. With supreme honesty towards his fellow workers, he applied his knowledge and created Microsoft Corp. with an aim to provide personal computers to the people of the world (Whyte et al., 2012). That is the reason that I admire this person, as the traits followed by him are the same that I want to throughout my professional life. Richard Branson is famous for his characteristic that allows him to step outside his comfort zone into new industries to face unique challenges (Alter, 2014). His journey began when in the year of 1968 he started a student magazine, which was followed by the establishment of The Virgin Mail Order in the year of 1971. This approach of Richard is similar to what stated in Hollands Career Typology theory of career development. In the year of 1981, he launched Virgin gaming organization and in 1984, he established Virgin Airlines, which shows that during different stages of his life, Richard experienced different roles. This phenomenon of his life is similar to the Supers Life-Span Theory of career development (Mitravich, 2015). However, he did not stop after this and added more diversity to his business by adding Virgin radio station in 1993; Virgin Cola is 1994, Virgin bridal wear in 1996 and Virgin trains in 1997 with in the brand name of Virgin (virgin.com, 2014). This much diversity and innovation in one person is extremely rare and can be compared with Hollands Career Typology Theory (Conklin et al., 2013). In spite of devoting, almost all his life to developing his business, Richard Branson never stepped back from social works. He always valued the importance of society and tried to contribute as much as he could to the same. Some examples are The Mia Farrow Pseudo Hunger Strike and The Trip around the world in a Balloon. This unique pattern of Richard to contribute to the society can be compared with the Trait-Factor theory of career development. He is also a visionary leader as he set a goal to not to pay taxes and that is why he successfully undercut the prices of well-developed retailers by avoiding the payment of purchase worth 500,000 in todays money (Meijers et al., 2013). This goal-setting characteristic of Richard Branson is something that is mentioned in the Krumboltz Social Learning Theory of Career Choice. From the above discussion on Richard Bransons career, it is clear that throughout his life he was a follower of adventure, competition, entrepreneurialism and fun. Innovation was another phenomenon that allowed Richard to jump into various business industries one by one. One of his major personal values is flexibility in the workplace. In Netflix, the employees are allowed to take as many holidays as they want without providing any prior notice to the management (virgin.com, 2014). Richard introduced this idea, as he believes in influencing the employees by different types of motivational practices. This act of Richard supports the theory of Krumbolzs Social Learning Theory of Career Choice. Richard, while doing his job with perfection also took proper care for his family. He always managed to take some time out of his family through delegations. He bought Necker Island in a bid only to impress his wife Joan during the time of their 40th anniversary. That clearly indicates his attach ment with his family, which allowed him maintain a work-life balance. References Alter, S. (2014).

It starts out with the well known line, the boy stood on the burning deck. The story relates to an extraordinary incident of devotion and heroism witnessed during the Battle of the Nile. It was on the evening of July 28 of 1798 that the English naval squadron under Lord Nelson sailed in. They had caught the French fleet at anchor and unprepared. The French flagship was the LOrient and it soon found itself flanked by English ships attacking from both sides. A fierce battle was soon raging and the flashes of 2000 guns lit up the ships in the gathering darkness. LOrient was caught by the English broadsides and was set ablaze. It was then that the English sailors saw an amazing sight. There on that burning deck they saw a boy standing alone. He was Cassabianca, the 12 year old son of one of the ships officers. There he stood, alone at his post. He was surrounded by flames and facing the astonished English foe. Soon afterwards the fire reached the powder magazine deep down in the hold. The boy perished when the whole ship erupted in a massive explosion. The sound of LOrient blowing up was heard at Rosetta 20 miles away. And the glow of the fireball was seen in Alexandria. It was an enormous explosion of a magnitude rarely seen back in those times. The English sailors stood in awe at what they had just witnessed. For some twenty minutes the guns were silent. The English officers and men were absolutely horrified at the carnage that had taken place. They sent a ship to rescue the survivors from the water. About 70 French sailors were saved. The account of that boy who stood on that burning deck was told and retold. Eventually it passed on into legend. The story remains a classic example of devotion and faithful service. And the poem continues to serve as a source of inspiration and wonder for many throughout Christendom. That boy who stayed at his post on that burning deck has not been forgotten. And the story of his heroic stand is remembered right up to the present day.

The manager being responsible for the entire work allocation has to responsibly check for the authenticity and the relevance of the data gathered. As a supervisor that is strategically investigating a situation (case) the first step is to number out what you need to pay attention to and what you don't. That is relevance. For example, you are offered with a scenario that involves employees who are chronically late for work and the data you have mentions that it is snowing. Is the detail that it is snowfall applicable or not? It cannot be confirmed due to the lack of detail. In addition, this further point towards the fact that in many positions trying to work from only the details offered is not enough. The supervisor should be astute sufficient to identify when added information is required, and what type of data, in order to consider the relevance of a specific piece of facts and figures. At the identical time he or she should understand when to make the decision with the data at hand. Often this step is resolved with a SWOT investigation, which farther extrapolates the most important issues out of the general situation investigation. This assists to zero in on the root problem (Heathfield, (n.d)). In the next step we determine the root cause of the problem where identification of the relevant problem is the main issue. This step is not a long drawn out explanation. You should be adept to state the difficulty in a sentence. It may then be essential, and in the comprehensive case or more convoluted positions a granted, to a complicated one with recognizing the actual problem which is the prime focus here. Next we look at the different parts of the problem where it is absolutely essential to find out the main components and then sort them out by making a list of points and ranking the aspects according to the needs. This is the most important step where one has to think out of the box and solve problems that are crucial. It is here that a kind of alternate courses of activity are identified and articulated. All of these are of course related to explaining the difficulty. This step is where you list the schemes you might chase. This is where you put your creative forces to work. In this part of the method, you should enlist in brainstorming. Remember that in brainstorming you easily generate concepts - save the evaluation of those concepts for later. That isn't to say in critical strategic case analysis you desire to include every concept you came up with in the report. In real world strategic planning I have seen reports that refer to the process and that it developed a number o f ideas that upon initial screening were very resolute as not reasonable or viable (Bradley at al, 2006). What you are doing here is not a full analysis of everything. When the case analysis report is written up it often appears as if these two steps have taken place simultaneously. That is not, or should not, be the case. Once you have narrowed the list you should take the information you gathered and analyzed in the first step and apply it to these alternatives. You should articulate what the most probable outcome will be based on the information you have collected, your experience, education, and expertise. When it is written up it is important to support your stated probable outcome. The next step is also important where it has to be kept in mind that the readers are going to assume things because the readers are always counting on you to make them understand the context in detail (Jackson, 2011). Thus it cannot be assumed that the readers will always understand and hence the content needs to be made clear for the readers to have complete comprehension of the same. Further it is also important to have the big picture in mind so that the readers

The History of the Italian Language

The History of the Italian Language You’re always hearing that Italian is a romance language, and that’s because linguistically speaking, it’s a member of the Romance group of the Italic subfamily of the Indo-European family of languages. It is spoken principally in the Italian peninsula, southern Switzerland, San Marino, Sicily, Corsica, northern Sardinia, and on the northeastern shore of the Adriatic Sea, as well as in North and South America. Like the other Romance languages, Italian is a direct offspring of the Latin spoken by the Romans and imposed by them on the peoples under their dominion. However, Italian is unique in that of all the major Romance languages, it retains the closest resemblance to Latin. Nowadays, it’s considered one language with many different dialects. Development During the long period of Italian’s evolution, many dialects sprang up, and the multiplicity of these dialects and their claims upon their native speakers as pure Italian speech presented a peculiar difficulty in choosing a version that would reflect the cultural unity of the entire peninsula. Even the earliest popular Italian documents, produced in the 10th century, are dialectal in language, and during the following three centuries Italian writers wrote in their native dialects, producing a number of competing regional schools of literature. During the 14th century, the Tuscan dialect began to dominate. This may have happened because of Tuscany’s central position in Italy and because of the aggressive commerce of its most important city, Florence. Moreover, of all the Italian dialects, Tuscan has the greatest similarity in morphology and phonology from classical Latin, which makes it harmonize best with the Italian traditions of Latin culture. Finally, Florentine culture produced the three literary artists who best summarized Italian thought and feeling of the late Middle Ages and the early Renaissance: Dante, Petrarca, and Boccaccio. The First 13th Century Texts In the first half of the 13th century, Florence was preoccupied with the development of trade. Then interest began to broaden, especially under the lively influence of Latini. Brunetto Latini (1220-94): Latini was exiled to Paris from 1260 to 1266 and became a link between France and Tuscany. He wrote the Trà ¨sor (in French) and the Tesoretto (in Italian) and contributed to the development of allegorical and didactic poetry, along with a tradition of rhetoric upon which dolce stil nuovo and Divine Comedy were based.The dolce stil nuovo (1270-1310): Although in theory they continued the Provenà §al tradition and counted themselves members of the Sicilian School of Federico IIs reign, the Florentine writers went their own way. They used all their knowledge of science and philosophy in a delicate and detailed analysis of love. Among them were Guido Cavalcanti and the young Dante.The Chroniclers: These were men of the merchant class whose involvement in city affairs inspired them to write tales in the vulgar tongue. Some, such as Dino Compagni (d. 1324), wrote about local conflicts and rivalries; others, like Giovanni Villani (d. 1348), took on much wider E uropean events as their subject. The Three Jewels in the Crown Dante Alighieri (1265-1321): Dantes Divine Comedy is one of the great works of world literature, and it was also proof that in literature the vulgar tongue could rival Latin. He had already defended his argument in two unfinished treatises, De vulgari eloquentia and Convivio, but to prove his point it needed the Divine Comedy, this masterpiece in which Italians rediscovered their language in sublime form (Bruno Migliorini).Petrarch (1304-74): Francesco Petrarca was born in Arezzo since his father was in exile from Florence. He was a passionate admirer of ancient Roman civilization and one of the great early Renaissance humanists, creating a Republic of Letters. His philological work was highly respected, as were his translations from Latin into the Vulgate, and also his Latin works. But it’s Petrarchs love poetry, written in the vulgar tongue, that keeps his name alive today. His Canzoniere had enormous influence on the poets of the 15th and 16th centuries.Boccaccio (1313-75): This was a man from the rising commercial classes, whose principal work, ​​Decameron, has been described as a merchants epic. It consists of one hundred stories told by characters who are also part of a story that provides the setting for the whole, much like The Arabian Nights. The work was to become a model for fiction and prose writing. Boccaccio was the first to write a commentary on Dante, and he was also a friend and disciple of Petrarch. Around him gathered enthusiasts of the new humanism. La Questione Della Lingua The question of the language, an attempt to establish linguistic norms and codify the language, engrossed writers of all persuasions. Grammarians during the 15th and the 16th centuries attempted to confer upon the pronunciation, syntax, and vocabulary of 14th-century Tuscan the status of a central and classical Italian speech. Eventually, this classicism, which might have made Italian another dead language, was widened to include the organic changes inevitable in a living tongue. In the dictionaries and publications of the, founded in 1583, which was accepted by Italians as authoritative in Italian linguistic matters, compromises between classical purism and living Tuscan usage were successfully effected. The most important literary event of the 16th century did not take place in Florence.
