Introduction notes - Essay Example In the cost strategy, devaluation is charged in the pay explanation against salary as a cost, and the estimation of the benefit subsequent to deducting deterioration is conveyed to the asset report. In the revaluation strategy, any expansion in future estimation of the advantage, is recorded to be determined sheet and is perceived legitimately in value under the head revaluation overflow. In the event that the future estimation of an advantage diminishes, at that point the abatement is recorded in the salary articulation as a cost thing. Representing the revaluation strategy is helpful if the future estimation of the benefits increment since the incorporation of revaluation surplus will build revaluation save, which will expand the estimation of value of an organization. In any case, if the future worth is nearly decline it is smarter to consider the cost strategy rather than the revaluation technique for the reason valuation of benefits on a drawn out premise. The motivation to this can be clarified with the assistance of a little model given underneath Question: A structure was bought by an organization on first January 2009 at an expense of $100million. The organization assesses the life-time of the advantage for be 50years, and hence the benefit is to be devalued over 50years. The organization chooses to utilize the revaluation for deciding the estimation of the structures toward the finish of 2015. The estimation of the structure toward the finish of 31st December 2015 was $80 million, as dictated by a proficient valuer. Answer: Using the revaluation strategy as selected by the organization Value of the structure on first January 2009= $100million Value of the structure on 31st December 2015= $80million Therefore, Accumulated Depreciation= $20million ($100million-$80million). Accordingly the incentive at which the advantage is to be conveyed in a critical position sheet on 31st December 2015 is $80million. In the event that the organization had picked the cost technique for deterioration, at that point Value of the structure on first January 2009= $100million Life of the asset= 50years Therefore, Accumulated devaluation toward the finish of 6years on 31st December 2015= $100million/50years * 6Years = $12million. Subsequently the incentive at which the benefit is to be conveyed in a critical position sheet on 31st December 2015 is $88million. Consequently, from the above model it tends to be reasoned that because of the utilization of revaluation technique, a revaluation loss of $8million was endured which is balanced against the current revaluation save of the organization. It likewise prompted the expansion in the estimation of deterioration and diminished the estimation of the benefit to be determined sheet. Increment in deterioration will influence the salary unfavorably, as it will prompt a diminishing of total compensation by $8million which will consequently affect the asset report and will likewise affect the investors. Thinki ng about the above representation, it is fitting to utilize the cost strategy to record the estimation of land and working of Rabbit Limited. In spite of the fact that revaluation strategy is considered to give an increasingly precise record regarding part substitution and deterioration, yet it is scrutinized because the measure of devaluation charged on a specific resource contrasts year to year however the advantage gives similar advantages, which make the bookkeeping framework complex and tedious, and some of the time it is said to have odds of control. So as expressed by the chief of Rabbit ltd. that the costs of the estimation of land are very nearly diminishing, so it will be smarter to utilize the

Analysis Of Homer s The Odyssey - 1533 Words

â€Å"Sing to me of the man, Muse, the man of twists and turns ... start from where you will—sing for our time too† (I, 1, 12). From the very beginning, Homer shows his intention for themes of The Odyssey to be applicable in the modern age and essentially â€Å"sing for our time† (I, 12). Homer’s epic provides the ideal reflection upon the very definition of heroism because it details the strenuous journey of Odysseus, a crafty hero whose key priority is to return home to his family. As one of the most prominent themes, The Odyssey carries forth the idea of heroism through the portrayal of Odysseus, and establishes a connection with the real world through the expression of life lessons. Consequently, Odysseus is characterized to serve as a role model for the successful hero because, after all, the poem is essentially centered on his very name. However, The Odyssey simultaneously conveys that an entirely perfect hero may be impossible, but a means for impro vement is always present. The attributes for success that are revealed in The Odyssey can be examined under interconnected ideas of passion, perseverance, and prowess. Thus, heroism is the most compelling theme of The Odyssey because it exemplifies the attributes for success while also demonstrating that heroes are not without mortal flaws. The attributes for success are vital to the meaning of heroism and rather obvious in the journey of Odysseus: passion, perseverance, and prowess. At the end of the Trojan War, the passion thatShow MoreRelatedAnalysis Of Homer s Odyssey By Homer1202 Words   |  5 Pagescoping with the idea of losing his father and letting others to rule Ithaca.

The Demise Of Earth s Doomsday - 1217 Words

An ongoing, redeveloping, catalyst-ensuing catastrophe known as â€Å"The End of the World as We Know it† has been hypothesized since humanity’s humble beginnings that predicts the apocalyptic theories for mass extinction, earth-crumbling events possibly dictating the end of the world. So far, all theories: scientific, religious, or phenomena-related, who yield a specific date for the end of the world have been debunked; creation of this essay would not exist otherwise. It is what looms in the future that theorists and educators such as Dr. F. Kenton Beshore and David Powell understand to be the demise of Earth’s doomsday.

Symbolism to the Journey Free Essays

Whether we are reading a poem or a short story, there is a story to be found within. The writer is able to capture readers with their use of rhythm, characterization, or a fairy tale setting, among many other things throughout their writing. It is imagination that allows us, the readers of these stories and poems, to be able to fill in the blanks or mentally visualize what the writer wants us to see through use of descriptive words or symbolism. We will write a custom essay sample on Symbolism to the Journey or any similar topic only for you Order Now In the poem â€Å"The Road Not Taken† by Robert Frost, the short story â€Å"A Worn Path† by Eudora Welty, and the short story â€Å"Used To Live Here Once† by Jean Rhys I noticed a common theme. No matter what lonely journey we find ourselves on, we determine how the journey ends. The lonely journey that each of these literary pieces tells about is presented differently in each writing. In â€Å"The Road Not Taken†, Frost used â€Å"Two roads diverged in a yellow wood† which told me that there was a forthcoming journey; he also used â€Å"and sorry I could not travel both† as a way to share that he had to make this decision of which path to take. Frost also used the word â€Å"I† many times, which allowed me to imagine him alone. In â€Å"A Worn Path†, Welty used the word â€Å"she† throughout the piece which gave me the image of this woman walking alone. The character spoke to animals â€Å"’Out of my way, all you foxes, owls, beetles’† and so forth. When the writer posed this conversation in the story, it gave me the feeling of loneliness. This woman was so lonely, she spoke to animals. The path that she was walking â€Å"ran up hill†. The idea that this path she was on was up a hill provided symbolism of a hard life. To me, walking up a hill would be hard work to get to the destination. Since the description of this woman had been of an aged woman, â€Å"her eyes blue with age† and her numberless branching wrinkles, it was a pity to find this woman walking alone up hill. In â€Å"Used To Live Here Once†, Rhys, too, used the word â€Å"she† many times to describe the character in the story. The usage of a singular word painted the picture of loneliness. â€Å"She was standing by the river† and â€Å"She came to the worn stone steps†. This woman was in this journey alone. In each piece of literary writing being discussed in this paper, the loneliness throughout the journey is clear. However, the ending to the journeys vary because of the choices the characters make. We will address this further on into the paper. The setting of a story or poem is what draws the reader in. I found myself reading â€Å"The Road Not Taken First†. The reason was that it starter out with almost a conflict of where the poem could take me. With the first line being â€Å"Two roads diverged in yellow wood†, I found myself wondering where the pathways would take me. As the poem began, I found it to be written in first person sine the writer used â€Å"I† as the main character term. Frost wrote â€Å"and be one traveler, long I stood†. This enabled me to actually step into the characters’, or the writer’s, shoes and see these pathways from his perspective. I like being able to feel as if I am in the story. Frost wrote about one path that it he could see where it â€Å"bent in the undergrowth†. He went on that the other path â€Å"was grassy and wanted wear†. This painted a picture for me of actual woods, split into two pathways, both different most likely ending in a different place. In the back of my mind, I had an idea that these were symbolic of something much bigger. The symbolism within the poem â€Å"The Road Not Taken† was abundant. â€Å"Two roads diverged could be seen as two things, two jobs, two ideas, two of anything that one could choose between. The word â€Å"yellow†, as used to describe the two roads in which Frost could choose is symbolic of aging or decay. To me, it seemed as if Frost could have been in a mid-life crisis, in which he felt old and needed change, and he had two new roads, of which the pathways and endings were unknown, to choose from. One path had been the one he was on, but did not know where it would end. The other road was grassy, seemingly vibrant, and the ending, too, was unknown. Frost referred to the both paths as â€Å"in leaves no step had trodden black†. In his description, the use of the word â€Å"black† shows symbolism of death. It seemed as if Frost was analyzing his choices and was seeing that his alternative pathway, although it did look enticing, he wondered why no one else had come back if they had taken that path. He knew that either path would ultimately lead to death, as that was his fate. There came a turning point in the poem where Frost went from indecisiveness to having made up his mind of his choice. Instead of being in front of two paths â€Å"in a yellow wood† he ended the poem that he was in just â€Å"a wood† in which he had chosen to stay â€Å"on the first for another day†. It appeared to me that his analysis of the paths he could choose from lead him to understand that the unknown is not as enticing as the known. According to John Savoie, the contradiction lies within the idea that both paths were â€Å"equally lay† but Frost chose to take the path of least resistance which indeed is arguable as there is â€Å"a lack of distinction between the roads†. (Savoie, 2004) His journey, although seemingly lonely, was determined by the decisions he made or would make. The second piece I read drew me in because the setting was not one of mystery, but instead it was one of pity. Used to Live Here Once† was the second piece I chose to read. The setting was one of sadness. I could visualize this woman â€Å"standing by the river† and â€Å"remembering each one†. It gave me the idea that she had been there long before but had forgotten the beauty of the river over time. Sad beginnings to literary pieces are not something that normal ly draws me in. However, the story grew more intriguing to me as the setting moved to her old home. When she noticed that â€Å"the screw pine was gone†, I still felt the pity and sadness for the character. Since the writer chose to write in a third person perspective, it was difficult for me to actually identify with the character personally. Rhys wrote â€Å"it was strange to see a car standing in front of it†. The personification of this car â€Å"Standing† in front of her old house was difficult to be considered strange since it was not an actual feeling of the character but instead an observation by the writer. In fact, the idea that the writer was this close to the character made me think she was speaking of herself in third person. Elizabeth Abel wrote a piece on Jean Rhys saying that Rhys’ writings typically subject us to â€Å"sparse and repetitive narratives† and â€Å"are variations of themes of failure and rejection. (Abel, 1979) This could be, perhaps, how the writer was able to make me feel as if, although told in third person, I was able to identify with her more closely. I was able to feel was the pity that the writer felt for the character through the words, such as when she spoke â€Å"shyly† to the kids but they did not hear her. This, too, solidifies the idea of Abel that Rhys wrote of perhaps herself in yet another rejected scenario. It seemed as if the journey was lonely for this character. The words â€Å"she† tells me this and also the fact that the setting is very calm and serene but without emotion from the character. From beginning to end, Rhys used symbolism to allow me, the reader, to relate and perhaps dig deeper into the meaning of things. The character stood by the river, which is symbolic of life. She did not walk into the river, she stood by it. This is symbolic of the entire story itself, since in the end of the story we find that the woman was indeed already dead and looking back into her own life. This was a journey that the character took alone. The character then walks down a road. This road is very symbolic to this story. The description is that the road is â€Å"much wider than it used to be†. This indeed tells me that the character took her life for granted. She had never truly taken the time to see the beauty in the things around her; this is why the road seems so much wider to her now that she has passed on. The day â€Å"was a fine blue day†. The color blue is used to tell the reader that it was a peaceful day. Rhys wrote on to tell us that the character noticed the pine tree was missing from outside of her own home, as her journey led her to her old doorstep. This is symbolism of immortality. Her old house had been painted white, which provides the feeling of life or purity. The character’s observation of the boy and girl playing in the yard was one that I will never forget. The colors of the yellow grass as she approached them and the gray in the boy’s eyes as the character tried to speak to him. This is when I first realized that the character was indeed a ghost looking in on her old life. The usage of colors throughout â€Å"Used to Live Here Once† is what drew me into this story. At my initial read of this story, I just thought that the writer liked colors. When linking these colors to symbolism, it gave me a much deeper perspective on what Rhys was trying to tell me, the reader. The lonely journey that this character was on was reflective of the lonely journey she lived when she was alive. It, once again, confirms that the decisions we make in life are what determine the ending of our journey. The last piece, â€Å"A Worn Path† had a setting that would draw in any reader who appreciates in-depth detail that, although in third persona narrative, makes you, the reader, feel as if you are standing there in the story along with the character. The setting throughout this story is indeed a pathway through the woods. Welty started the story out with â€Å"a bright frozen day early in the morning†. I hate being cold, personally, but Welty’s initial setting description made me feel excited to see what would happen if I read on further about the events on the â€Å"frozen day†. According to journal writer, James Robert Sanders, â€Å"the story begins conspicuously on a cold December morning, and just as quickly we are made aware that there is an old black woman†. Suanders, 1992) Continuing my reading, I found the character, again noting the use of the singular â€Å"she† throughout the piece, to be â€Å"an old Negro woman† â€Å"along a path through the pinewoods†. Welty described this woman as â€Å"very old and small and she walked slowly†. The pity set in on me at this point to think that a lady of her age was walking alone in the woods. She carried a cane, â€Å"made from an umbrella†. The setting, although starting out in an exciting manor, had, at this point, turned more so into pitiful. She seemed destitute by this fact. There she was, in the woods alone, using an umbrella to swat through the brush to ensure there were not any animals hiding along her pathway. When Welty wrote that â€Å"the sun made the pine needles almost too bright to look up at†, it brought me back to the excited feeling again. It was as if the story had gone from exciting to pitiful and fearful back to exciting again. I felt like Welty was trying to keep a positive spin on a negative situation. Continuing on with the reading, I found the character again in a battle, but this time with thorns from a bush. Once she freed herself from the thorns, she said â€Å"sun so high† which again gave the offset to the negative event. Shortly after, the character was faced with a log that she must cross over a river. This woman could not catch a break on her journey but still she kept going with intent to succeed and make it to her destination. Within the story â€Å"A Worn Path†, the symbolism, the personification, and the tone are what made this story most appealing. The story, itself is interesting. However, when you add in the extra benefit of symbolism, the reader can get a more in-depth look and feel for what the writer is trying to make us feel. This story, told in third person narrative, starts out on a â€Å"bright frozen† morning. This symbolism provided me with a feeling of hopefulness. Although it was frozen outside, it was bright. The character walked down a path. It seemed she only had one path to walk down. Her only choice was actually going down that path or not to. Her eyes were blue which gave me the feeling of peacefulness. Her face was described with golden color beneath her wrinkles and yellow color under her dark cheekbones. This symbolism gave me the idea that although she was aged and seemingly poor, she still possessed dignity and pride. To describe the wrinkles on her face, Welty personified a little tree to be standing in the middle of the character’s forehead. Immediately, I was able to visualize this much better than I would have without this connection. The character continued on her path in the â€Å"sun† and cold, passing pine trees, thorns, and speaking to animals. The sun is symbolic of life. However, being winter outside, we know this by the use of the word â€Å"frozen† to describe the weather; we know that this is symbolic of death. I took this to mean that the character was dying but trying really hard to fight to stay alive. Along her path, these hurdles, the thorns, the logs and creeks, the path being uphill, passing through a cotton field, the field of dead corn, her speaking to animals and imagining people along her journey in the woods, this is all part of the symbolism of things she was fighting to stay alive. It was her struggle. She began dancing with a scarecrow, something that is supposed to scare away birds, or in this case death, and here she was dancing with it. It just shows her eagerness to stay alive and fight off the negativity, the death. Although she seems crazy throughout this journey, her own focus, the one thing that she stays sane in regard to, is life and her desire to stay alive. When the character started to walk through â€Å"trees silver in their dead leaves† it was certainly symbolic that death was shortly forthcoming. Just as I start to think she is about to die, she comes upon a spring and sweet gum and water. It was as if she was being given one more chance. She laid there on the ground and had a dream that â€Å"she reached her hand up, but nothing reached down and gave her a pull†. This dream symbolized to me that God was not ready to take her, not just yet. That is when the hunter found her. The hunter felt pity on her and I understand this because he says he would have given her money if he could. In town, she asked a lady to tie up her shoe for her before she reached her final destination. Her need to be presentable for her entrance into the medical building to get her grandson’s medicine shows that she still has class and self-respect. Her journey to the medical building, although alone and difficult, was made possible through the love for her grandson. Had she not made that trip, her grandson would have died. Each of these literary pieces was different by means of the nding to the journey in which the character had taken. â€Å"The Road Not Taken† was a solitary journey to make the decision of which path in life to take, the one we know or the one we do not know. â€Å"Used to Live Here Once† was another solitary journey of a life after it has already passed by; it was a lesson that we should not take for grante d the things in life, although simple. â€Å"A Worn Path† was one more solitary journey, but this one taught a lesson that love can conquer all. Each journey I read for this paper has taught a value life lesson. The journeys we take are altered by the decisions we make along the way. How to cite Symbolism to the Journey, Papers

Any illegal act contrary to what is required by GAAP, FASAB, or IRS would then implicate the CPA themselves if they continue support or represent that client. The CPA should never disclose any of the clients personal information unless given permission or in the case of fraud/crime to the proper authorities. It’s my belief that a client should never feel sheltered from fraud/crime to government agencies. 2.) Yes, I do not think there should be a sense of a CPA protecting a client when there is fraud/crime.

Ethics (relating to information technology) Essay

Ethics (relating to information technology) - Essay Example An action may be legal but unethical or illegal but ethical." (Any classification of ethics is considered as being the study of particular values and customs of a person or group, and applied ethics are most commonly used in the information technology field. This is an "applied discipline of philosophy that attempts to apply ethical theory to real-life situations. The lines of distinctions between meta-ethics, romantic ethics, normative ethics, and applied ethics are often blurrybut it can also depend more on general normative principles, such as possible rights of self-rule and right to life." (Frauenheim, 2006). The applications here are enormous, and the issue of ethics is one of the most major and significant within this. The given article relates very strongly to the issue of ethics then, as it discusses how ethics is presented relating to e-businesses: due to the convenience that is brought to the table by these e-businesses, the issue of ethics changes quite a bit, because now the general public does not have to leave their home and drive anywhere anymore, they can simply access everything that they need from their computer in the comfort of their own home.

Discuss and assess the potential for multiplied penalties for Assignment

Discuss and assess the potential for multiplied penalties for egregious violations. Your response should be approximately 200-300 words and include a reference citation for your sources - Assignment Example Some companies are crying foul because according to them it was practically issuing multiple citations and penalties for the same violation (MacArthur, 1995). Furthermore, since the OSHA provision is for prevention of the same hazards from occurring again, it is improper to multiply the penalties by the number of employees harmed by a violation. There is no need to multiply the penalty because the same hazard can be remedied with the â€Å"identical abatement method† (MacArthur, 1995). If OSHA is allowed to execute these multiplied penalties, they might go overboard and start issuing penalties on a per day or per hour basis on every violation made. This is definitely unreasonable and unacceptable to employers. OSHA should view the matter in the proper perspective focusing on the fact that if the hazard can be corrected just once, then there is no need for multiplied penalties. However, if different hazards represent different violations, then the penalties should be multiplied because it cannot be corrected by a single action. MacArthur, M. (1995, December 1).

Molecular Modelling: Explained

Molecular Modelling: Explained Molecular modelling is one of the fastest growing fields in science, but what is it and what does it mean? â€Å"Molecular modelling encompasses all theoretical methods and computational techniques used to model or mimic the behaviour of molecules. The techniques are used in the fields of computational chemistry, drug design, computational biology and materials science for studying molecular systems ranging from small chemical systems to large biological molecules and material assemblies. The simplest calculations can be performed by hand, but inevitably computers are required to perform molecular modelling of any reasonably sized system. The common feature of molecular modelling techniques is the atomistic level description of the molecular systems. This may include treating atoms as the smallest individual unit (the molecular mechanics approach), or explicitly modelling electrons of each atom (the quantum chemistry approach).†[1] As stated, molecular modelling is a way to notice the interaction of a molecule with a molecular system. The best way currently to carry out this process is through computer modelling, but it is still plausible to perform the simplest of studies through the use of molecular mechanics or through the use of a notepad, pen and calculator. However the main concern is that most of the time it may be necessary to carry out molecular modelling through computer modelling as it can be very difficult to work out some of the calculations by hand, whereas the computer can accomplish this for us. So what is it? Furthermore to this all, molecular modelling is an expanding topic with more and more developments occurring within the field as the days go on. New scientific papers and methods are being posted as well as an increased amount of journals being published. From this we can see that it’s a topic with a huge variety knowledge and background. This is justified alone from how many issues there are with the problems where molecular modelling can be applied and the abundance of methods that can be used. The journals and papers written about molecular modelling also go into detail of theoretical chemistry and computational chemistry. As a result of this, it is very hard to keep up with molecular modelling techniques and theories due to the fact that there is an increased knowledge of the field as each day goes on. Thanks to the role of the internet, scientists are able to access more journals and papers to find articles on the relevant field they are interested in studying. This in tu rn also means that there are articles directed for all readers to understand, whether you know nothing at all to someone who is a researcher in the field of theoretical chemistry. The brilliance of this all is that there are documents of research, which keep up to date with only the recent developments, so it’s a quick fix for some scientists to see what they’ve missed out.[2] Molecular modelling is alternatively know as molecular mechanics. The basis of the method is to work out the structure and calculate the energy of molecules from their nuclear motion. The idea of how molecular modelling works is assumed on the Born-Oppenheimer approximation of the Schrà ¶dinger equation. This meaning that the approximation states that nuclei, due to their mass being greater than electrons, move more slowly. As a result we can identify the nuclear motion of nuclei separately to that of electrons and therefore the rotations and vibrations can be studied alone assuming that electrons move fast enough to adjust to any movement of its nuclei. Through the use of force fields, we can calculate the energy and geometry of a molecule. This creates the measure for molecular modelling. A force field is a collection of atom types, parameters and equations. By looking into further examples, we can show how molecular modelling is used. Looking into the idea of force fields, we can see that certain atoms have several atom types. We can look at compounds like ethylbenzene, which contains hybridised carbon atoms and aromatic carbon atoms. Through this, we can further explain it to show the parameters of force fields in different bonds as ethylbenzene has different C-C bonds, which are present in the ethyl group and phenyl ring. The total energy of a molecule is separated into different parts named force potentials. These are calculated separately and then added together to give the total energy present within a molecule. These force potentials are what are associated with the equations for the energies with bond stretching, bond bending, torsional strain and van der Waals interactions. E(total) = E(stretch) + E(bend) + E(s-b) + E(torsion) + E(vdW) + E(dp-dp) Energy due to Bond Stretching If a bond within a compound is stretched or compressed, the energy of the bond increases. The form of calculation for the potential energy for a bond stretching and compressing is a similar calculation to that of Hooke’s law for a spring, except a cubic term is included. As a result of the cubic term, it helps to keep the energy from rising too sharply when the bond is stretched. Energy due to Bond Angle Bending When bonds are bent away from the standard degree, the energy increases. However, there are some exceptions for the calculations of this energy, as cyclic compounds provide special atom types and parameters, which are used in the force field. Energy due to Stretch-Bend Interactions Bonds will stretch to release tension when two bonds have their angle reduced. Through the use of cross term potential functions, we can take into account the terms of bond stretching and bond bending together. Energy due to Torsional Strain intramolecular rotations require energy. The torsional potential is a Fourier series that accounts for all one to four through-bond relationships. Energy due to van der Waals Interactions The van der Waals radius of an atom gives its effective size. As two non-bonded atoms are brought together, the attraction increases causing a decrease in energy. If the distance between the two non-bonded atoms equals the sum of the can der Waals radii the attraction is at a maximum. The closer the atoms are brought together, the greater the energy and the greater the van der Waals repulsion. Energy due to Dipole-Dipole Interactions The calculation for dipole-dipole interactions is similar to that of Coulomb’s law. We can calculate it by considering all the interactions in a molecule. If there is a net charge present in the molecule, calculations must be carried out for charge-charge and charge-dipole.[3] To put this all into layman terms, molecular modelling varies from the construction and imaging of simple molecules to creating computer simulations on large protein molecules. Through the use of advanced computer software, we can visualise, rotate, optimise and manipulate molecular models. Some calculations can take up to a few seconds but there are models where it would take months to produce results.[4] What is it used for? Molecular modelling allows us to create a greater visual aspect to show the shapes of molecules and show how they interact. It is used vastly in certain fields, such as, Biology. An example of this would be through enzymes. Their substrates, receptors and their signalling. As of this we can see how useful and how certain molecules interact with one another forming complex molecules where we can then evaluate how strong the binding affinity is and how it would visually be seen. The biological activity of a drug molecule is supposed to depend on just one unique shape amongst all low energy structures. Through the use of molecular modelling, we can search and target these bioactive conformations. Molecular modelling allows us to identify the atomic and molecular interactions that control the behaviour of a physical system. The molecular interactions that would be identified would be those mentioned above to work out the energy of the force potentials. One of the first approaches to calculating molecule-molecule binding free energy differences was through the use of comparative molecular field analysis (CoMFA) [Cramer et al., 1988], which allowed us to understand and interpret the active sites of enzymes without a crystal structure being present. Molecular mechanics allows us to find the best viable solution in which we can model large and non-symmetrical chemical systems. This can be for molecules such as proteins and polymers. Through the use of the classical laws of physics, molecular mechanics allows us to predict the chemical properties of molecules. The issue with this is that we cannot calculate or deal with bond breakage or formation where the treatment of electrons dominate the effects. We tend to turn to molecular mechanics for comparative results rather than absolute quantities. For example, a force field is an empirical approximation for structure-energy relationships in molecules, which allows us to show a comparison between speed and accuracy. We can produce a better, or even, a more realistic geometry value for the vast majority of organic molecules, due to the fact they are highly parameterised thanks to molecular mechanics. Molecular dynamics is highly dependent on Newtonian mechanics. this is a conformation space search where atoms are given an initial velocity and are then allowed to evolve in the time. [van Gunsteren Berendsen, 1977]. The issue with molecular dynamics is that we have to use minimisation schemes, but if we take a look at the effects of temperature, some molecules can overcome the potential energy at the surface. Through the use of simulated annealing, we can control these issues at present [Kirkpatrick et al, 1983, Cerny, 1985]. This allows us to use molecular dynamic calculation in which the system temperature is raised to a large value to allow a spread of exploration of the available conformational space. With an increase in dynamics, the system temperature would be decreased. The last phase would be to use minimisation to select a minimum energy molecular conformation.[5] Molecular Modelling Challenges There are numerous challenges that pose in the way of molecular modelling. They range from the lack of knowledge about certain species of molecules to the free energy calculations that are taken place. There has been vast development in knowledge within areas such as in gene databases. The issue is, there is a lack of information in the laws of protein folding for example. There is only so much we know about sequence information but with the little intelligence we have about protein folding, it restricts the inference of structure from sequence. A novel approach scans a pathological vector victimisation the tools of molecular biology; of the various relevant proteins made, a couple of are often isolated, crystallised, and structurally elucidated. The structures of traditional and pathological molecules are often compared and compounds designed to inhibit pathogenic enzymes or receptors by selection. distinguishing the targets is that the initial downside we tend to encounter. So with the structure of even one target protein, and therefore the information of function of its receptor or active site, its currently doable to use computer tools to make and dock a ligand or inhibitor before investing time and resources for synthesis and testing. Conversely, large-scale screening might detect â€Å"new leads† that then should be modelled so as to explore later synthetic analogs. In either case, molecular modelling is crucial for understanding and exploring the structure-function relationship. attractive and repulsive forces are often summed and therefore the work quantified. Ideally, one seeks a correlative listing of experimental and computational values to offer assurance that novel compounds are often evaluated before being synthesised. However, there still are exceptions and sudden surprises (Meyer et al., 1995) that has to temper the passion of the molecular modeller. Based on Fischer’s â€Å"lock and key† simile, the mechanical view of molecular interactions are often understood and applied to biomolecules. However, even â€Å"rigid† molecules have local flexibility and fluxional water molecules are typically a structural appendage of each the â€Å"lock† and therefore the â€Å"key,† which implies the in vivo structure might disagree considerably from that on the display screen. Therefore, modelling code must have a choice to simulate the presence of pervasive water molecules. Molecular mechanics calculations will solely seek the local energy minimum, however are unable to climb the pass into the next energy level. Molecular dynamics simulations are a strong tool for inclusion of the fluxional nature of biomolecules and in best circumstances, will explore the energetic landscape in search of the energy minimum. Atomic parameters are approximate and based on a generic, classical atom, whereas these parameters change modify in a fluxional structure, thus quantum molecular dynamics is required. This field has however to mature, and necessary computational resources greatly exceed today’s supercomputers, to not mention the PC. Again, however does one treat water rigorously (dielectric constant, ionisation state, fluxional H-bond- ing; bulk vs. microscopic quantities)? Challenge #3 could be a rigorous computational simulation of a biochemical reaction in an exceedingly in a accessible to the synthetic chemist, as mentioned by professor Ursula Roethlisber ger (ETH Zentrum, Zà ¼rich, Switzerland) at this symposium.[6] Another big issue is the topi that there is extreme difficulty in calculation free energies by computer. Free energy is often considered to be the most important value when looking into thermodynamics. It can be expressed in two ways, Helmholtz function or Gibbs function. Both work similarly in the sense that they both work with only a constant number of particles and a constant temperature, but Gibbs free energy works with also a constant pressure (NPT) and Helmholtz works with a constant volume (NVT). Most experiments that are carried out, it is best suited to use the Gibbs function as most conditions are kept under constant temperature and pressure. The issue with all of this, is that free energy calculations are difficult to carry out then working with liquids or flexible macromolecules as they have far too many minimum energy configurations separated by low-energy barriers. Other calculations that are difficult to carry out are those such as entropy and chemical potentials. Through the use of the Monte Carlo simulation or ‘standard’ molecular dynamics, it is still very difficult to calculate free energy because said simulations do not sufficiently sample the regions of phase space, which contribute greatly to free energy. The two simulations, molecular dynamics sampling and Monte Carlo, are used to find the lower-energy reasons of phase space. as a result, the sampling data will not show reflection of the high-energy regions, so calculating free energy through simulation tends to give inaccurate values. Another problem is the calculation of free energy differences of two states. We can approach these issues mentioning the simulations above. Three methods have been proposed; thermodynamic perturbation, thermodynamic integration and slow growth. From these we can calculate the free energy differences. New methods for calculating free energy changes can be worked out with errors no more than 1 kcal / mol in certain cases. Through the use of the two different simulations, one of the initial system and one of the final system. The energies calculated from the two systems are large numbers, with a great error. The difference would be comparable in magnitude to the error in the energy of each system. We determine what the free energy is in terms of interactions involving the solute, which in turn allows us to give a more accurate reading in energy calculations. The two energy systems calculated, are large numbers with a great deal of error, but from this we can take the enthalpy difference and error difference then compare them in magnitude. From this, free energy is calculated based on the interactions involving the solute, therefore we can calculate free energy much more accurately. When looking at the major sources of error with free energy calculations in computer simulations, they can result from inaccuracies in potential model choice or its implementation. Our other source of error comes from the phase space, by collection insufficient sampling. The main issue is the fact that we cannot find a method that guarantees adequate coverage of phase space, meaning it is hard to calculate free energy values. We can identify the inadequate sampling through two methods, we can run the simulation for an increased duration, so using the molecular dynamics simulation, or for an increased amount of repetitions, so the Monte Carlo simulation. We can perform this in both the forward and reverse directions, so a different scheme can be use to calculate the free energy difference. Most of the time, the simulation is run in both directions, and from this, we can calculate the lower-bound estimate of the error in calculation from the different in free energy values. One thing we have to be cautious of is the fact that we need to be careful when carrying out these simulations, because when we cary out more than necessary amounts of simulation over a short simulation, estimating errors is a lot more difficult because the results give a near zero difference between the forward and reverse directions. If the time of simulation exceeds that of the relaxation time of the system, then it is possible to carry it out reversibly. However, if the time of simulation is that of the same order of magnitude as the relaxation time then approximately zero hysteresis may result. This would be due to the incapability of the system to adjust to the changes. Within this, free energies in both directions could appear to be the same and as a result, quite likely to be wrong.[7] [1] Molecular modelling Wikipedia, the free encyclopedia. 2014.

African Americans and Racial Diversity

There are many organizations that advocate equality for African Americans in the United States. Many organizations will promote the African American race and show what concerns are being felt by their race. Those that advocate for their race give a description of how they fall in history, what discrimination they endured and what prejudice they still have to deal with. These groups and organizations promote the idea to bring discrimination to a stop in their cultures around the world. African Americans and Racial Equality African Americans have made their way to freedom, but have been left with a heavy burden of their ancestor’s slavery. Would they ever be seen as anything but slaves brought unwilling from Africa to the United States to be enslaved and be servants to the White Man? Those questions can be answered by looking at the history of African Americans and how they have become great leaders in this country. Rosa Parks may have not been the first Black woman to give up her seat on the bus, but she stared a chain of events that would eventually bring segregation to an end. That day in 1955, Rosa Parks paved the way for people like Barak Obama to become the first African American President the United States has ever had. Before that time, African Americans had endured slavery, segregation, discrimination, and prejudice because of the color of their skin. Many African American men fought for our country in the civil war so they could be granted freedom after they served. Butler (2013) stated, â€Å"the Fourteenth Amendment was added to the Constitution revoking that fateful decision and ensuring citizenship, with all its rights and esponsibilities, to everyone born in the United States regardless of race. † (para. 1). There have been several political, social, and cultural issues and concerns throughout American history. Some political issues African American have faces according to history. house. gov (2013) â€Å"Since 1870, when Senator Hiram Revels of Mississippi and Representative Joseph Rainey of South Carolina became the first African Americans to serve in Congress, a total of 139 African Americans have served as U. S. Representatives or Senators. Social issues among African Americans are discrimination and prejudice within the United States and beyond. Many are discriminated against because of their race. Many black men and women are deprived of the earning abilities of that of the White man. They make less money and live in poverty striking communities. Because of slavery, many African Americans feel as though they will never been seen equal to others because of their ancestors. Until this mind set changes, history will continue to run the ideas and future of African Americans. Some cultural issues among the African American throughout history would be being accepted into a culture. Many slaves when freed started large communities made up of just Blacks. Without the same education and opportunities as White men and woman, they fell into poverty and struggled to grow as respected Americans. This permits for crime rates to be higher because they had to survive any way they could if only by stealing to be able to live. These issues among African American still exist today. The NAACP has fought for African American rights for generations. According to â€Å"Naacp: 100 Years Of History† (2009-2013), â€Å"The NAACP seeks to remove all barriers of racial discrimination through the democratic processes. † (Founding Group). The have helped many African American groups with their right to vote because even after they were granted the right, many were still denied. The NAACP has fought along site African Americans to bring justice and rights to those people who worked so hard to become free and receive equal rights in the United States. The United States Supreme Court alleviated slavery, and wrote into law that ll people should be treated equal. They gave African Americans the right to vote and be equals in their communities and states. They also were granted the right to become government officials. Although these laws have been added, discrimination and prejudice still exist in the United States. The NAACP and other organizations have and continue to fight for the rights of African American and other races. Blackradicalcongress. org has a list of originations that promote blacks in our country. These groups give support to African Americans and show the history of their culture. African Americans may carry a heavy burden of slavery from their ancestors, but they have become the staples of our culture. Through their determination our country has changed to make way for new opportunities for us to grow as a Nation. Every man has equal opportunity to make change and live a life without discrimination and prejudice. It takes one person to show the world that change can happen. Let’s make a change. Let’s all live without discrimination and treat everyone as an equal to ourselves.

Can Blake Be Considered To Be a Romantic Poet

Romantism was an artistic movement, which took place between 1770 and 1848. It highlighted a significant change in society. Before, people generally believed in the neo-classic system, which was extremely authoritarian, there was no belief in the power of imagination, paintings were realistic portraits or landscapes and literature was inflexible. Everything was more or less constrained. Signs of romatism were evident in writers such as Mary Shelly and ETA Hoffman who both alluded to the darkly mysterious aspects of life. Slowly writers started to portray nature in relation to mans sentiments (Gray was a fine example of this). This is displaying imagination, as it is associated with the individuals' state of mind. Rousseau was a great influence in the Romantic Movement, his literature showed adventure and a clear use of imagination. William Blake was an ardent follower of Rousseau and his beliefs. This is evident in his poems, such as The Tiger taken from Songs Of Innocence. In this poem there is a contest between the tiger and the blacksmith, the tiger being a natural, powerful, instinctive and full of energy and imagination while the blacksmith ruins, crafts and reconstructs natural materials. It is clear in the poem that Blake had a great degree of respect for the tiger and this is shown where it says: â€Å"On what wings dare he aspire? What the hand dare seize the fire.† This is taken from the second stanza of the poem, which consists solely of questions. These questions are evidence of Blake's fascination with this creature that is individual in thought and action, that isn't influenced by Urizen and is not affected by the mind forged manacles. It is evident in this poem that Blake was a believer in the power of imagination. He loathed anything that limited or constricted imagination. This is partly from the influence of Jean Jacques Rousseau's The Social Contract, the opening sentence resembles key words that appear in Blake's poems: â€Å"Man is born free but everywhere he is in chains.† Here, the key words are â€Å"free† and â€Å"chains†. Chains are mentioned a countless number of times in Blake's poems, most noticeably in The Tiger where it says: â€Å"What thy hammer? What thy chain?† A hammer is a weapon that shapes (resembling how the church/monarchy shaped society) and a chain is a weapon that restricts and Blake obviously felt that people were being oppressed. As well as having respect for individual and instinctive creatures like the tiger, Blake was also very fond of children. Many of his poems are based on children with a particular emphasis on childhood memories, for example: The Chimney Sweeper and The Nurses Song. Both of these poems appear in two parts, each with one in Songs of Innocence and the other in Songs of Experience. This emphasises the value of individual experience. If we look at The Nurses Song (Innocence), it is clearly portraying a feeling of joy and optimism; this is evident where it says: â€Å"When the voices of children are heard on the green And laughing is heard on the hill.† Here, the words: â€Å"voices† and â€Å"laughing† tell us that children have a voice and are allowed to have a voice, and be expressive. Also, the emphasis on the surrounding environment makes the setting very idyllist (like that of fairy tale). The key concept to this poem is authority. In this poem the nurse is benevolent and lenient. However, in the NUSRSES song (experience), the key figure (the nurse) becomes jealous and self-centred, this is portrayed where it says: † The days of my youth rise fresh in my mind, My face turns green and pale.† Now the nurse has envy in her soul, she wants to be like a child again because experience has made her so cynical. Here, there are two important points, one is experience, Blake is showing us how people change with experience, after being constrained and oppressed people became self – centred and envious like the nurse. The other factor is childhood, he is emphasising the sacredness and vitality of that part of life. As this is the only time when we can be completely frank and voice our thoughts without hesitation and its accepted. By analysing Blake's poetry and imagery it is clear to see that he can be considered a romantic poet. It is clear to see in The Tiger that he believes in the power of imagination and this is also evident in all his work. He emphasises on the value of experience a great amount and this is most obviously shown by the composition of Songs of Experience. All his work shows a subjective point of view, which is expressed through the intensity of the language he uses. He has linked together man and nature (most noticeably) in The Sick Rose and The Clod and the Pebble. All his work reflects his state of mind, he is conveying his point of view through his literature and art forms, and this makes him a romantic poet.

Real-World Green Chemistry Examples

Green chemistry seeks to develop products and processes that are kind to the environment. This can involve reducing the waste a process creates, using renewable materials, lessening the energy required to form a product, etc. The US Environmental Protection Agency (EPA) sponsors an annual challenge for the most innovative green chemistry inventions, plus you can find examples of green chemistry in many of the products you buy and use. Here are some interesting sustainable chemistry achievements: Biodegradable Plastics Plastics being developed from eco-friendly renewable sources, plus some modern plastics are biodegradable. The combination of innovations reduces our dependence on petroleum products, protects humans and wildlife from undesirable chemicals in old plastics, and reduces waste and impact on the environment. Scientists at  NatureWorks  of Minnetonka, Minnesota, makes food containers from a polymer called polylactic acid, made using  microorganisms to convert cornstarch into a resin. The resulting polymer is used to replace rigid petroleum-based plastic used in yogurt containers and water bottles. Advances in Medicine Pharmaceuticals are expensive to produce in part because of the complicated and exacting synthesis mechanisms required to produce some drugs. Green chemistry seeks to streamline production processes, reduce the environmental impact of drugs and their metabolites, and minimize toxic chemicals used in reactions. Professor Yi Tang, of the University of California,  devised an improved  synthesis process to make  Zocor ®, which is the brand name for  the drug, Simvastatin, used to treat high cholesterol. The previous process used hazardous chemicals and released a large volume of toxic waste. Professor Tangs process uses  an engineered enzyme and a low-cost feedstock. The company Codexis, then took the mechanism and  optimized the enzyme and synthesis process so the drug could be manufactured more safely, less expensively, and with less of an environmental impact. Research and Development Scientific research employs a number of techniques that use hazardous chemicals and release waste into the environment. New greener processes keep research and tech on track while making it safer, cheaper, and less wasteful. Life Technologies  developed a three-step, one-pot synthesis method for polymerase chain reaction (PCR), used in genetic testing. The new process is more efficient, consuming  up to 95 percent less organic solvent and releasing up to 65 percent less waste compared with the conventional protocol. Using the new process, Life Technologies  eliminates about  1.5 million pounds of hazardous waste each year. Paint and Pigment Chemistry Green paints go way beyond eliminating lead from formulations! Modern paints reduce toxic chemicals released as paints dry, substitute safer pigments for some poisonous colors, and reduce toxins when the paint is removed. Procter Gamble and Cook Composites and Polymers formulated a soya oil and sugar mixture to replace petroleum-derived paint resins and solvents. Formulations using the mixture release 50% fewer hazardous volatile compounds.Sherwin-Williams created water-based acrylic alkyd paints that contain low levels of volatile organic compounds  (VOCs). The acrylic paint is made from a mixture of acrylics, soybean oil, and recycled PET bottles. Manufacturing Many of the processes used to make products rely on toxic chemicals or could be streamlined to reduce the use of resources and release of waste. Green chemistry seeks to develop new processes and improve conventional production methods. Faraday has developed a plating process to make high-performance chrome coatings from trivalent chromium instead of highly toxic hexavalent chromium.
