Density of Common Substances

Density of Common Substances The table below shows the  density of some common substances, in units of kilograms per cubic meter. Some of these values may certainly seem counter-intuitive- one would not expect mercury (which is a liquid) to be more dense than iron, for example. Notice that ice has a lower density than either water (freshwater) or seawater (saltwater), so it will float in them. Seawater, however, has a higher density than freshwater, which means that the seawater will sink when it comes in contact with freshwater. This behavior causes many significant ocean currents and the concern of glacier melting is that it will alter the flow of seawater- all from the basic functioning of density. To convert the density to grams per cubic centimeter, merely divide the values in the table by 1,000.

Economic data analysis using software STATA Essay

Economic data analysis using software STATA - Essay Example variables; GDP, the rate of inflation, the rate of un-employment, long term interest rate, short term interest rate, the CPI-consumer price index an, the money supply (M) and regression analysis done using STATA. When investing, you are most likely to hear the terms inflation, unemployment, Consumer Price Index (CPI) and Gross Domestic Product (GDP) about every day (Barnes, R 2007). Investors are often made to feel that these terms should be looked deeply as a surgeon would study a patients chart prior to operating (Barnes, R 2007). Countries really need to find a level of understanding which can assists them in decision making without engaging piles of data to solve the problem. Inflation in the increase in the  money supply. It can also mean an increase in price levels for different commodities. Generally, inflation is about a prices increase as compared to some set levels (Richmond, H 2006). According to Gay, A (2006), if the money supply goes up, this is usually manifested in higher price levels for commodities, however, he continues to state that, this manifestation takes only a short while and that, it is simply a matter of time. According to Dawson, G. et al. (2006), Gross Domestic Product in a country represents the total aggregate output of its economy. Further to him, the GDP figures which are reported to investors and those that want to invest are already adjusted for inflation. For example, if the gross GDP is calculated to be 6% above than the preceding year and inflation calculated at 2% over the same period, then the GDP growth would be reported as 4% (6%-2). The relationship between inflation and GDP is like a delicate dance where any can break affecting the masses (Dobson, S & Palfreman, S 1999). The annual GDP growth is vital for each and every country in that, if the overall economic output declines or holds steadily, then many organizations will not be in a position to increase profits which is the sole driver of stock performance in all of

The robotic technology will be useful at the NIPR, SIPR and JWICS levels. The NIPRNet will basically be depending on high speed of the UGVs for transportation of data records to the headquarters in order to allow faster relying of data across the network. The information relayed across the network is not confidential but faster reliance would enable the private users to gain the necessary information conveniently. On the other hand, the NIPRNet would benefit from the UGVs through taking advantage of both their speed and high security of records while in transit. The network deals with highly confidential information that has to be secured effectively while eradicating all loopholes to security including human error. Therefore, the UGVs will be depended upon to transport manual files to the agency buildings for effective sharing of information across the network. Finally, the JWICS will benefit from the UGVs through securing effective sharing of material resources by the Department of Homeland Security, Department of Justice, Department of Defense and Department of State. This factor will ensure faster and reliable sharing of highly sensitive classified materials between the

Relationships in Charlotte Bronte’s Jane Eyre Essay Example for Free

Relationships in Charlotte Bronte’s Jane Eyre Essay ‘To what extent is Jane Eyre influenced by relationships in chapters 1-10 in the novel?’ Relationships are a key theme in Charlotte Bronte’s Jane Eyre. Throughout the novel we see the rise and fall of Jane, all most importantly due to relationships. This starts primarily with her lack of relationship with her parents, as she was orphaned when she was very young, she has no idea what it is like to love or to be loved and we see her strive to find out these feelings throughout the novel, until finally she achieves it, but the journey towards this is deeply important. In chapters one and two we see the basis of Jane’s view of relationships through her connection with the Reed’s. Firstly Mrs Reed does her upmost to make sure Jane is excluded from her and her ‘contented, happy, little children’ we as readers see this as a cruel act from Mrs Reed, she does not care that Jane is deeply unhappy because Jane is not one of her children, therefore she does not see it as her duty to care for her emotionally and thinks by punishing her and excluding her from the family that this will teach Jane to be a ‘contented child’ however we as readers see that this causes Jane to be deeply troubled within herself. This leads to Jane not only resenting Mrs Reed but also her children as they have been taught that Jane is a ‘dependant’ especially John who ultimately sees himself as above Jane in every aspect of life, he believes that Jane is just scavenging off them and this causes him to act in a horrific and bullying manor towards Jane. This causes Jane to act in a way she ordinarily would not, she even says herself that it causes ‘sensations for the time predominated over fear’ she feels so angry and let down that she finally stands up for herself. Therefore this influences Jane in a way that she feels like nobody will ever truly love her and she feels very much an outcast, this causes Jane to act in a way that even she herself expresses that she does not want to, she is cold and unloving and strives desperately to be appreciated but of course, this all happens in vain. We also see Jane to act very irrationally towards Mrs Reed, she deeply wants her to love her, yet w hen it comes down to it and she realises Mrs Reed never will she has an explosion of anger and tells Mrs Reed all the things that have been stewing up in her mind for so long; ‘I am glad you are no relation of mine. I will never call you aunt again as long as I live. I will never come to visit you when I am grown up; and if anyone asks me how I liked you, and how you treated me, I will say the very thought of you makes me sick. . . .† this we  see as Jane being bitter towards Mrs Reed which we learn in later chapters as a very uncharacteristic feature of Jane Eyre, she is usually forgiving. The relationship between Jane and the nursery maid; Bessie is an important one, in the first few chapters we see Bessie as being somewhat cruel and dismissive of Jane compared to the other Reed children, she does not feel a connection towards Jane as she is not as pretty or funny as the other children therefore Bessie does not see her appeal. However after the event in the red room we see a change with Bessie’s attitude towards Jane, she turns somewhat softer as we see her feel sorry for Jane and how hard Mrs Reed is on her. This is an extremely important turning point in the novel as we see Jane in the chapters leading up to this as very self involved and saddened as she has no one to love, yet as soon as Bessie softens to Jane and tells her that she can sympathise with the position she’s been put in she tells Jane ‘I don’t dislike you, Miss; I believe I am fonder of you than of all the others.’ This affects Jane greatly and we see a completely different little girl, she seems to talk which much more glee and excitement and even for her ‘life had its gleams of sunshine’. So we see how much relationships influence Jane and her attitudes in the novel, relationships affect Jane and how her personality is. In chapter five Jane meets Helen Burns, Helen is also an orphan and see’s the school as somewhat of a sanctuary even though she is constantly picked upon by the teacher. Helen is Jane’s first friend but more importantly she becomes Jane’s best friend and we see as the relationship grows that Helen deeply influences Jane, she teaches her to be less excitable and too see the best in others, a quality that Jane desperately needs after her experience with the Reed’s. She teaches Jane to be self sacrificing when she tells her ‘it is far better to endure patiently a smart which nobody feels but yourself, than to commit a hasty action whose evil consequences will extend to all connected with you’. Helen believes that you should suffer pain yourself than have others see and feel an action that you may regret when you have calmed down. Jane learns from this and this causes Jane to be a character who thinks beyond this life and onto the next with God. We see Jane finds this as a great comfort and now instead of looking onto God as something to be feared, she looks at him as somewhat of a comfort, especially after Helen dies of typhoid. Helen believes that after she dies she is going to be with her family and loved  ones and most importantly with God, therefore she does not fear death and although Jane is deeply distraught by the death of the only friend she’s ever had in the world, the fact that she will, if she lives correctly see her again is a great comfort. This shows the importance of friendship throughout the novel and how with Jane having the comfort of a friend she can be the person that she has always wanted to be, thanks to Helen Jane finds herself acting more appropriately and being able to handle her anger. Therefore this relationship has greatly affected Jane as she strives to be more like Helen. Relationships are of key importance to Bronte writing about Jane Eyre, it is how she expresses her feelings of how relationships have perhaps affected her and it shows how deeply the lack of love can affect someone. This novel is primarily about love, whether it being a lack of love or so much love that it turns into passion, Jane strives to feel this emotion and closeness with anyone who will allow her to be their friend. Therefore relationships are a key influence to Jane Eyre, they affect how she acts and how she feels and without them, as we learn in the first few chapters, life can be a very lonely existence.

Life is like a box of chocolates Essay

At first glance the quote ‘life is like a box of chocolates seems’ rather silly. How could such a large and complicated concept such as life be compared to something as small and simple as a box of chocolates? There have been two opposing viewpoints in regards to the meaning of this quote, and each viewpoint comes about by a different analysis of what life and chocolates represent as well as what they mean in today’s world. The conclusion to the question can only come about through a thorough examination of the quote itself along with its possible entailments to see what both groups of people deem important and what they choose to ignore. Both arguments seem to work well to counter the other and show the flaws in the other explanation’s theory. According to the World Book Encyclopedia, life is ‘a state, existence, or principle of existence conceived as belonging to the soul.’ Most people, when questioned about life would not have a very clear or concise answer because life is not something that is wholly tangible. In general life is considered to be everything that happens to a person from the moment they are born to the moment they die. All of their interactions with the world and all of their thoughts and actions. There does not seem to be any plan or order to these events, just everything that happens. Everything. Life is a long process with good, bad and indifferent points. According to the World Book Encyclopedia, a box is ‘a container, usually with four stiff sides, a bottom, and a lid to pack or put things in,’ and chocolate is ‘a substance made by roasting and grinding cacao seeds.’ A box of chocolates would logically be a container which holds cacao products. A scientific dissection of a box of chocolates would show a box (usually rectangular or heart shaped) filled with anywhere from one to dozens of small, individually wrapped chocolates. Usually the type of chocolate and the filling of each individual varies inside a given package. In America however, a box of chocolates means much more then this simple addition of definitions and a direct visual analysis would lead one to believe. A box of chocolates, in our referent system, is a symbol. It generally symbolizes  love, and through metonymy, has been made to mean love. When a gift of a box of chocolates is given on Valentine’s Day, it more than symbolizes love, it actually means love. The meanings have become blurred over the years as chocolate has become a standard gift. It is not an original thought to give someone chocolate, but more a means of showing love. Not an act of love, but merely an expression of love. The first group of people generally finish the simile ‘life is like a box of chocolates’ with the conclusion ‘you never know what you’re gonna get.’ This group views all the meanings of life and of the box of chocolates and found the best compilation to be that both in life, and in chocolates, there is randomness and a lack of order. When a person walks out of the front door of his house on a Monday morning, there is no way for him to know if he is going to find a hundred dollar bill tucked under his doormat, or a large meteor that has fallen and crushed his car. It’s hard to know if a day is going to be a good day or a bad day, you just know that it will be a day. The same holds true for eating a box of chocolates. When you open a box of chocolates, there are rows of non-differentiated chocolates. They all look the same, and yet you know some are filled with cream, some with caramel and some with coconut. When you pick one up, much like when the man opens his front door, there is no way of knowing if you will get a good chocolate (cream) or a bad chocolate (coconut), you just know you’ll get a chocolate. For both examples it will not be easy to tell if it was good or bad until the chocolate, or the day, has been completed. You never know what will happen. The second group of people generally finish the simile ‘life is like a box of chocolates’ with the conclusion ‘a thoughtless perfunctory gift that nobody really wants.’ This group takes up an opposing analysis and says that the important part of chocolates is not the randomness of them within the package, but instead the symbol that people don’t really think in life, but instead just perform as they are expected to. Since chocolates have come to mean love, people no longer do creative things to express their love. They simple buy chocolates. Once the chocolates are delivered, then what. People don’t actually want the chocolates, they want the love. Since the chocolates  have assumed the meaning of love, the chocolates themselves go to waste. Who wants to eat their love? Instead of being eaten immediately, as chocolates are truly intended to be, they are showed to friends and relatives, and eventually put on a shelf or in a cabinet. They will get eaten if someone shows desire, but it’s not important. Under this interpretation, life is pointless and merely for show. People don’t do things because it is what they feel that they should, people do things because they are expected to (just as the lover is expected to give chocolate). It is better to put up an lofty facade, then to be true and honest to the people around you.
