Pied Beauty Poem Analysis free essay sample

Hopkins masterfully uses figurative language to convey imagery that leads to the readers appreciation of the mental pictures the poet is attempting to convey. In the poems title, Pied indicates the kind of beauty that Hopkins will praise—multi-colored things, and is defined as having patches of two or more colors, as various birds and other animals:The poems first phrase grabs the reader with a familiar religious line, Glory be to God. This sets the tone for the rest of the poem by praising all of the images Hopkins will present in Pied Beauty. Another central focus of the poem introduced in the first line is diversity, specifically to sensory details that appeal to ones sight, by using the word dappled, which is defined as having spots of a different shade, tone, or color from the background; mottled. Dappled means things that do not conform in color to a background: they stand out. We will write a custom essay sample on Pied Beauty Poem Analysis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Hopkins sees patterns of color, each divergent from its surroundings. He describes the colors of the sky the colors are presented in a variety of hues or shades. For skies of couple-colour as a brinded cow He compares the skies (using a simile) to a brindled cow (here referred to as brinded), meaning gray or tawny with darker streaks or spots. highlighting multiple colors or shades. Hopkins lists the many things in nature that catch his eye. For rose-moles all in stipple upon trout that swim Hopkins describes role-colored moles or spots in the pattern of stipple—an artistic method using dots or small touches. In essence, nature is art. Next are the colors of autumn trees: this image is brilliantly presented to clearly describe the color change in leaves as the colder weather arrives; and he couples this image with the colors of birds wings: Fresh-firecoal chestnut-falls; finches’ wings The poet also describes the land as it is being farmed or left to grow wild. (It is noted by one source that the land takes on this appearance as man uses it: mans intervention in the natural landscape. ) As the ground is plowed (ploughed), the turned earth is one color. If it is fallow—not being seeded—all that grows are weeds or wild flowers, thus presenting a different color. (Fold refers to the pasture where sheep graze, a third color. ) In these colors and patterns, Hopkins seems to liken the earth to a quilt, with a metaphor: Landscape plotted and pieced The poem concentrates a great deal on nature, but also draws attention to the appearance of men in various trades, and how they look in am array of clothes and tools: gear and tackle and trim. In the second stanza, Hopkins becomes more general, listing the ways things are different: counter, original, spare, strange;Whatever is fickle, freckled With swift, slow; sweet, sour; adazzle, dim Then, the last two lines turn our attention back to God, where Hopkins began. He notes that God is the creator of all these things, and His beauty is beyond change. The poet reminds us, in light of all the beauties of nature, that God should be praised. As a side note, Hopkins particularly uses alliteration to catch our ear:Glory God; couple-colour; Fresh-firecoal, falls, finches; plotted, pieced; fold, fallow; and, trades, tackle, trim. The repetition of these sounds appeals to our auditory sense, drawing our attention to his words in yet another way, and giving the poem a musical sound

Mr. President essays

Mr. President essays I take exception to a few key aspects of Pres. George W. Bush's initiatives. I guess I should start by saying that Pres. Bush doesn't want us to know about his plans to saddle the economy with crippling debt. Otherwise, we might do something about that. I, hardheaded cynic that I am, want to give people more information about Pres. Bush, help them digest and assimilate and understand that information, and help them draw responsible conclusions from it. Here's one conclusion I decidedly hope people draw: This is a lesson for those with eyes to see. It is a lesson not so much about Pres. Bush's unprofessional behavior, but about the way that the choice we face as a nation is whether to run our country ourselves or let vicious dummkopfs run it for us. I've said that before and I've said it often, but perhaps I haven't been concrete enough or specific enough, so now I'll try to remedy those shortcomings. I'll try to be a lot more specific and concrete when I explain that the baneful nat ure of Pres. Bush's precepts is not just a rumor. It is a fact to which I can testify. In case you have any doubts, Pres. Bush says that governments should have the right to lie to their own subjects or to other governments. What he means by this, of course, is that he wants free reign to condemn children to a life of drugs, gangs, drinking, rape, incest, verbal abuse, physical abuse, and a number of other horrors. We should reinforce the contentions of all reasonable people and confute those of blinkered Machiavellians. (Goodness knows, our elected officials aren't going to.) I can no longer get very excited about any revelation of Pres. Bush's hypocrisy or crookedness. It's what I've come to expect by now. Pres. Bush maliciously defames and damagingly misrepresents everyone and everything around him. There's a word for that: libel. We are observing the change in our society's philosophy and values from freedom and justice to corruption, decay, cynic...

Macbeth Essay Example | Topics and Well Written Essays - 1250 words

Macbeth - Essay Example When considering all of this, Hamlet’s contemplation and indecisiveness certainly seem justified. We are forced to think about death and the afterlife by the play. The actions of the play are forced by the death of Hamlet’s father and the ghost’s appearance, and Hamlet contemplates death and suicide throughout the play. Death plays a large part in the theme of uncertainty throughout the play. We have no idea what happens after we die, and so we can no idea as to what happens afterwards. Because we do not know what will happen, we do can not know if we are making the correct decision in regards to questions of suicide. Hamlet ponders this very question in his most famous soliloquy, â€Å"To be or not to be† (III.i.56-86). He comes to the conclusion that people would only deal with the pain and suffering of life precisely because the there is so much uncertainty in everything dealing with the afterlife. The ghost’s existence is another factor to consider when thinking about the afterlife. The ghost’s existence seems to confirm the existence of an afterlife in the world of the play, but it does not state what kid of afterlife actually exists. The ghost has apparently come to seek out vengeance for wrong doings from his life, but we have to consider that it might merely be an evil spirit that is just trying to create trouble. There are many cues throughout the play to suggest as much. Because we cannot know the nature of the afterlife until we are actually dead, we cannot know for certain what the intentions and goals of the ghost really were. The ghost simply adds to he uncertainties. Hamlet is certainly left with more of his fair share of questions to ask himself: â€Å"Was I deceived by the ghost? How am I to do the deed? When? Where? What will be the consequences of attempting it—success, my death, utter misunderstanding, mere mischief

Poem 2 – The Destruction of Senacherib 8 A. Personal Analysis 8 A.1. How the Poem Fits into the Era 8 A.2. Literary Analysis 8 VI. Poem 3 - Darkness 9 A. Personal Analysis 9 A.1. How the Poem Fits into the Era 9 A.2. Literary Analysis 9 VII. Conclusion 10 Works Cited 11 I. Introduction A. Thesis Statement What seems to stand out from the poetry and from the life of the man, is that of Byron like his poems depicting a kind of beauty that is detached from ordinary reality, and yet so much more beautiful for being so, detached yet somehow real and palpable, and utterly heroic. This seems to represent in one way what Romanticism is all about (Byron; Brooklyn College English Department; Academy of American Poets; Poetry Foundation). B. Brief Overview B.1. Literary Era The literary era to which Byron and his poetry belongs is the era of Romanticism (Brooklyn College English Department). B.2. Biography The poet was born into royalty, and was able to inherit a title, so that by age of 10, he became Baron of Rochdale. His father died at a young age, and he was full of resentment for his mother. He died at the age of 36 (Academy of American Poets) B.3. ... that we inherit the convenient set of terminal dates for the Romantic period, beginning in 1798, the year of the first edition of  Lyrical Ballads  by Wordsworth and Coleridge and of the composition of  Hymns to the Night  by Novalis, and ending in 1832, the year which marked the deaths of both Sir Walter Scott and Goethe. (Brooklyn College English Department) B. Defining the Era, Characteristics of the Poetry There is an emphasis on the individual, the individual as a hero, where the personality is supreme, elevated. Imagination has a central place in Romanticism too, which also likewise was put up in a pedestal as being the best part of the human mind and consciousness. Symbols and symbolism, as they pertain to nature, for instance, were also highly valued. Feelings were given emphasis, especially as with regards to the expression of feelings in poetry (Brooklyn College English Department) C. Era in the Context of British History 1798 marked the year of the Irish Rebelliion , marked by a period of intense conflict between Britain and its neighbor, culminating in union (Bartlett). This period was also marked by the turn of the century struggle between Napoleon on the one hand and Britain on the other, all the way to 1802 (History World). C.4. Era in the Context of World/Global History and Events Elsewhere in the world Napoleon was brought down also during this period, at Waterloo in 1815, and the slaves were finally emancipated in New York around 1827, when slavery was outlawed in that state (Taylor) C.5 How Byron Fits Into This Era Byron was a leading voice of the Romantic era. He is credited with having a large influence on the movement and on the Romantic poets and artists in general, especially with his poem â€Å"Don Juan†. The term â€Å"Byronic hero† is also

Strategic mgt. process applied to project managemt Dissertation

Strategic mgt. process applied to project managemt - Dissertation Example The Execution Premium Process or XPP is a comprehensive and integrated management system which combines strategy formulation, planning, and operational execution (Kaplan and Norton, 2008). Program management on the other hand refers to the coordinated management of a selection of projects in order to attain benefits which are deemed strategically important for an organisation (Reiss, 2006). XPP is comprised of six stages: (1) strategy development; (2) strategy planning; (3) organization alignment; (4) operations planning; (5) monitoring and learning; and (6) strategy testing and adaptation. This system was developed due to a need for a framework to which various strategy and operational management tools could be utilized (Kaplan & Norton 2008; Shelldrake, 2011). Strategy development involves the formulation of organizational strategies by addressing three crucial factors: (1) mission, values, and vision; (2) key issues; and (3) the strategy itself. Organizations need to be clear with regards to their purpose, the principles by which everyone is guided in their actions, and future aspirations. An organization needs to reaffirm their mission, values, and vision as an initial step in strategy development (Kaplan & Norton 2008). ...   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The next step involves a review of the organization’s competitive and operating environment. Managers need to utilize three sources for the review: (1) the external environment; (2) the internal environment; and (3) the status of the current strategy. Issues concerning the external environment may be identified through the use of the PESTEL tool which stands for political, economic, social, technological, environmental and legal. Meanwhile, issues pertaining to the internal environment include human capital, innovation, operations, and technology deployment (Kaplan & Norton 2008). Another tool used is the SWOT which is described as a table wherein the strengths, weaknesses, opportunities, and threats to the organization are laid out for review. Information gathered at his point will be utilized to develop a strategic change agenda which rationalizes the need to identify and address challenges. Meanwhile, the third step of this stage involves the de velopment of a new strategy based on the information collected from the previous steps. Factors such as the market niche, customer value proposition, key processes, human capital, and technology are likewise involved (Kaplan & Norton 2008). The second stage of XPP involves creating a strategy plan through the development of guidelines for strategic objectives, measures, targets, initiatives and budgets. Likewise, this stage determines how resources are allocated for each component of the plan. This stage is comprised of five components: (1) creation of strategy maps; (2) identification of measures and targets; (3) selection of strategic initiatives; (4) allocation of funds and resources; and (5) establishment of theme teams (Kaplan & Norton 2008).

Pellet Catalyst Development using Ferroxcube Process

Pellet Catalyst Development using Ferroxcube Process Pellet catalyst development using the Ferroxcube process The pellet preparation followed the classic routine of the powder metallurgy industry (NTUA): hematite (Fe2O3) or magnetite (Fe3O4) powders were homogenized in a plasticizer and greasing environment, within a rotating pan (Figure 7). Consequently, disks were pressed in a 150 bar hydraulic press (Figure 8). NTUA used the experience of CERTH (coordinators of the HYDROSOL projects to proceed in the proper preparation of the pellets). Figure 7. Rotating panFigure 8. The 150 bar hydraulic press After the initial pelletization by the hydraulic press, the pellets were undergone sintering and reduction in a controlled atmosphere (oxygen-reduced atmosphere) oven as shown in Figure 9, in order to obtain the magnetite phase certified by XRD, as shown in Figure 10. Figure 9. The sintering oven.Figure 10. XRD response of the sintered pellet, certifying the magnetite phase The porosity of the pellet and the neck development, offering substantial mechanical properties, have been monitored by SEM, as shown in Figure 11, as well as by the classic pressurizing methods. This way, the magnetite pellets have been stabilized in mechanical, electric and magnetic properties, offering mechanical robustness and electric resistivity below 10 Ohm or 3 à ¯Ã‚ Ã‚ ­Ohm.m (non-used pellet). Furthermore, an advanced manufacturing process has been proposed by the SUN Unit to the above-mentioned industrial technique. During sintering and reduction process, magnetic field can be added externally to the sintering and reducing ovens to magnetically orient the magnetite dipoles in the desired direction, allowing for advanced Lorentz force control. 2.2. A thin-film catalyst We have conceived and developed a thin film device for the hydrogen production which can be integrated in an automated system. The device can also be used for the reduction and oxidation process in oxide semiconducting films supported by metal substrates-wafers, even if they do not exhibit coherent magnetic order. The method is based on the Lorentz forces acted on the reducing oxidizing conducting electrons in the said oxide semiconducting films. Hence, this device can trap oxygen and hydroxyl from transmitted water, thus producing hydrogen. This such reduction and oxidation process in open air, as well as controlled atmosphere conditions. A particular application, useful for the HELENIC REF project refers to the three-layer depicted in Figure 15. The upper layer consists of a magnetite film not thicker than 500 nm, an insulating thin film supporting the magnetite film, not thicker than 500 nm and finally a metallic wafer made of Al or other metal, supporting the insulating and the magnetite thin film. Figure 15. Schematic of the catalyst Possible manufacturing methods include electrodeposition, physical vapor deposition, chemical vapor deposition as well as lithography and masking methods for the generation of electric contacts on the upper thin film. Concerning Fe3O4 (magnetite) film, a preferable but not obligatory condition is to be able to provide magnetic order in all grains of the ferrimagnetic cells of the oxide. This is achieved by magnetic field during deposition or by post-processing magnetic field annealing with subsequent field cooling. The desired properties of the Fe3O4 (magnetite) film are indicatively as follows: Structure of the magnetite phase, which can be certified by X-ray powder diffraction Multi-grained microstructure with small necks between grains, monitored by Electron Microscopy Resistivity below 10 kOhm, indicative of semiconducting phase Magnetic order, observed by monitoring the magnetic hysteresis loop Mechanical robustness observed by hardness and wear measurement Applying electric current through the metallic support of the film results in magnetic field parallel to the surface of the film and vertical to the applied electric current. The amplitude of this field is: Where I is the applied electric current and a the thickness of the film. If the thickness a (sum of the magnetite film and the insulating thin film) are less than 1 à ¯Ã‚ Ã‚ ­m and the current I is C Amperes, then the applied field is: Thus, the applied field is controllable by the applied electric current through the metallic support. This current can easily be in the order of one Amperes in dc mode or several tens of Amperes in pulsed mode, if the thickness of the metallic support is in the order of 100 à ¯Ã‚ Ã‚ ­m, thus allowing the transmission of magnetic field larger than 1 T in the vicinity of the oxide semiconducting film. Therefore, passing electric current through metallic support, one can simulate the magnetic field vertical to the direction of electric current passing through the magnetite thin film. The directions of these two electric currents characterizes the direction of the Lorentz force on the conducting electrons of the magnetite film. Parallel currents result in forcing the electrons towards the insulating thin film, while anti-parallel currents force them towards the surface of the magnetite film. These two different directions of Lorentz forces have a different effect on the operation of the magnetite thin film, acting as catalyst for the production of hydrogen. Passing electric current along the magnetite film, independent on the electric current passing through the metallic substrate of the magnetite film, (i.e. from another source), along the same direction of the current transmitted to the metallic substrate, results in a Lorentz force acting on the charge carriers (electrons) moving them from the surface towards the insulating thin film. Thus, the surface of the magnetite film becomes activated, in other words is reduced due to the removal of the mentioned Lorentz electrons. Activation is the generation of electron vacancies, offering the generation of new oxygen vacancies (excess of oxygen vacancies). Thus, the resistivity drops, and the applied voltage results in higher current, which increases the local temperature to 280 320C. Such temperature increase is observable by any kind of pyrometer. The temperature increase is dependent on the combination of the electric current passing through the oxide semiconducting film and the magnetic field transmitted to it due to the electric current passing through the metallic support. The effect is reversible and un-hysteretic: increase or decrease of the amplitude of I x H product, where I is the applied current on the oxide film and H the field resulting from the current on the metallic substrate, results in un-hysteretic and reversible increase or decrease of the temperature and reduction of the oxide film respectively. Such activation can be maintained even in open air: the competition between the Lorentz electrons based reduction and the free air oxidation finally results in oxidation which can also be macroscopically observed by the decrease of the activated (reduced) area on the free surface of the film. Having limited the current passing through the metallic support may result in activation (reduction) shrinkage. In this case, increasing the current transmitted to the metallic substrate before the radiation disappears, or before oxygen vacancy excess disappears, the oxygen vacancy excess is rejuvenated. Such rejuvenation is completely reversible by using the magnetic field produced by the current passing through the metallic support (in the order of 1 T). After complete oxidation (phase transformation of all the Fe3O4 film to Fe2O3) such oxygen vacancy excess and consequent reduction of the compound is impossible with magnetic fields of this order. The reduction and oxidation process can be monitored by measuring the surface resistivity of the magnetite film. Such resistivity depicts the increase or decrease of oxygen vacancies on the surface and consequently the bulk of the oxide pellet. Increase and decrease of this resistivity is equivalent to the oxidation and reduction of the resistivity of the surface respectively. This effect is observable in all types of oxide semiconducting films even in the absence of coherent magnetic order in them. To be able to observe this effect in oxide semiconducting films, they should be in a continuous solid state form, exhibiting even a small electric conductivity, and provided that magnetic field and electric current of proper waveform and amplitude are simultaneously applied on the semiconducting oxide film and the conducting (metallic) support. Such reduction mechanism can be used in the reduction of compounds passing on or through the film surface. Our focus is the reduction of pure vapor water to H2, by means of trapping the oxygen or the hydroxyl of the water molecule to the reduced (or activated) magnetite. Such oxidation with consequent hydrogen production can be reversed back to oxide reduction (activation) by means of stopping the water vapor transmission. This way, the two electric currents will reduce (activate) again the surface of the oxide film, provided that no water vapors are transmitted to the pellet surface or body. A certain application of such effect is the use of the said pair of Fe3O4 (magnetite) film with its metallic support for the production of hydrogen and oxygen from water vapors, using the following algorithm: Independent electric currents pass through the metallic support and the oxide semiconducting film in the same direction. Thus, the surface of the oxide semiconducting film is reduced (activated). Then, water vapor is transmitted on the surface of the oxide semiconducting film, resulting in oxygen trapping, hydrogen production and oxidation of the surface of the oxide semiconducting film. As soon as the resistance of the surface of the oxide semiconducting film exceeds a certain threshold, indicating reach to a critical level of oxide film surface reduction, the water vapor transmission is stopped. Thus, the oxide film surface is re-activated, followed by consequent oxygen release, until the resistance of the oxide film surface reaches a minimum threshold, indicating proper reduction (activation), which is proper for oxygen trapping. Then, water vapor is re-transmitted to the re-activated oxide film surface for hydrogen production. The production of hydrogen and oxygen is followed by an automatic storage of these two gases in different chambers to be used for any scope, like thermal combustion or fuel cell operation or other purpose. Development of the thin film catalysts The Dynamic Hydrogen Bubble Template (DHBT) is an excellent method for the fabrication of macrostructures with nanoporous side walls. The method has been named from the phenomena when a series of hydrogen-bubbles generated on the surface of the substrae act like a dynamic negative template. Figure 1 demonstrates the theoretical approach of the technique. Figure 1(a) illustrates the hydrogen-evolution taking place on the surface there is no metal/metal-oxide deposition. The size of the bubbles increasing along the distance from the substrate surface. Fig 1(b) shows the SEM-image of copper nanofoams prepared by DHBT. Figure 1. (a) Simplified description of DHBT generated metal/metal-based foams; (b) Honeycomb-like Cu-deposit structure made by DHBT. The electrochemical deposition procedure of the development of the catalyst is divided in two main parts. At first preliminary experiments on deposition of magnetite film were carried out in order to determine the orders of amplitude of the different involved parameters (current density, geometry etc.). , the electrochemical deposition of iron-oxide films was carried out as a preliminary approach. Based on the results of the characterization, the parameters of the deposition were varied in a high range in order to obtain 3D-structured porous nanofoams. The films were electrodeposited onto copper substrates (purity: 99.5%). The substrates were mechanically polished with 800 and 2000 emery papers, respectively. Henceforward, the polished substrates were ultrasonically cleaned in deionized water, ethanol and acetone, respectively. The 2 cm2 active surface area of the substrate was ensured by commercial nail-polish and insulating tape. The galvanostatic deposition was carried out in a two-electrode cell using a DC Power Supply. Platinum-mesh was used as counter electrode. Two different arrangement of the working electrode have been tested as shown in Figure 2. The electrolytic bath was a strongly alkaline solution with pH 12.5 made of 0.037 M Fe2(SO4)3.x H2O, 0.1 M triethanolamine (TEA) and 2 M NaOH. After mixing the components at T = 80 à ¯Ã¢â‚¬Å¡Ã‚ °C the solution had greyish-green color and no turbidity was observed. The parameters of the deposition process were varied in the terms of current density, bath temperature and deposition time. The range of cathodic current density was chosen j = 5-15 mA.cm-2, the depostion time was given from 5 min to 6 hours and the bath temperature was adjusted T = 60-90 à ¯Ã¢â‚¬Å¡Ã‚ °C. The nominal thicknesses of the prepared structures were calculated by using the Faraday-law. The surface morphology of the deposited film-layers were studied by scanning electron microscope (Nova NanoSEM 230) and the crystallographic characterization was determined by X-ray diffraction (Bruker D8 Advance, Cu radiation-40kV, 35mA). Figure 16. a) copper triangle used as working electrode (W) by turning the active surface towards the surface of the electrolyte b) copper-plate (W) used as working electrode by immersing it totally and by turning the active surface towards the counter electrode (C). Concerning the development of 3D-structured porous films, the substrate deposition was not changed (Cu-foil, purity: 99.5%). SiC polishing papers were used in grade of 800, 1500, 2500 and 4000, respectively as a surface pre-treatment. All the pre-treated samples were ultrasonically cleaned in deionized water, ethanol and acetone, respectively. In that case, the active surface area of the substrates was reduced to 0.5 cm-2 and fixed with nail-polish and insulating tape. The galvanostatic deposition was carried out in a two electrode cell using a BioLogic SP 300 potentiostat. Platinum-wire was used as counter electrode. Concerning the result of the film-deposition the arrangement of the working electrode was set in vertical position. The electrolytic bath, concentrations and its properties were the same as described above. The cathodic current density was varied in the range ofj = 0.075-1 A.cm-2, the depostion time was changed between 30 sec to 180 s and the bath temperature was adjusted T = 90 à ¯Ã¢â‚¬Å¡Ã‚ °C. Similar films have also been developed by using sputtering deposition and electron-gun aided deposition (Figure 17). Apart from the electrolytic method, thin magnetite films were also deposited onto insulating films by usign spuutering and electron gun physical evaporation at the NTUA. However, the obtained results on the porosity of the magnetite films are not comparable with the DHBT method and therefore they are not demonstratable at their current stage. Nevertheless, experiments are under way to obtain PVD films of the quality observed in the electrodeposited films. Characterization of catalysts Structural analysis The catalyst pellets were prepared by a proprietary process from Fe3O4 powders. IP SAS used Fe3O4 powder with declared purity better than 99% and nominal grain size of 2-4um supplied by chemicalstore.com, product code FE3O4M1. The phase composition determined by XRD (X-Ray Diffraction) is shown in Figure 38. Minor traces of Hematite can be observed at 32.8 ° 2Theta for the sample produced at IP SAS. Figure 38. XRD patterns from pellets prepared by SUN (red) and IP SAS (blue). Marked constituent phases are Magnetite (blue lines) and Hematite (black lines) A typical XRD response in the bulk SUN pellets and in bulk CERTH pellets is illustrated in Figure 1, demonstrating exclusive magnetite presence. Figure 1. XRD response of bulk pellets from SUN (left) and CERTH (right) illustrating exclusive presence of magnetite Phase transformations were studied by the means of in-situ XRD presented in Figure 41. Samples were mortar milled to obtain a fine powder that could be spread on the sample holder of the furnace. Milling force was kept minimal to preserve the structure of the pellet parts. Linear heating with indicated rate was used to obtain well-defined diffraction maxima with respect to the signal to noise ratio. Diffractometer was configured for parallel beam illumination with a secondary LiF monochromator to supress fluorescence from the Fe containing pellets. Formerly purely magnetite pellets are transforming to hematite in the vicinity of 300 °C. After the transformation no other phase change was observed. Pellets supplied by SUN exibit the transformation at higher temparature than the pellets prepared at IP SAS. This can be atributed to the smaller size of the Fe3O4 crystallites in the SUN pellets. Detailed pattern examination is shown in Figure 42. The studied powdered pellets exhibit only presence of magnetite and hematite respectively. Diffraction maxima at 26 ° 2Theta corresponds to SiO2 present as a thin layer grown on the non-reflective Si sample holder. Figure 41. In-situ XRD patterns of catalysts in air atmosphere with indicated heating rate Figure 42. In-situ XRD patterns of annealed catalyst pellets at indicated temperatures. Marked constituent phases Magnetite (blue lines) and Hematite (black lines).Catalyst prepared at SUN left, IP SAS right. Crystallographic study of the iron-oxide thin films samples was also realized. Figure 4 represents the identification of the observed peaks. Figure 4(a) shows the results of sample prepared in 3300 s in 70 à ¯Ã¢â‚¬Å¡Ã‚ °C bath with -5 mA.cm-2 current density. Grazing incidence XRD patterns of this sample indicate the presence of magnetite (blue lines) and copper substrate (green lines). Grazing angle was 2 (red curve) and 6 degrees (blue curve), respectively. In Figure 4(b) the results of sample with same conditions as in Figure 4(a) can be seen, but in this case the current density was -9 mA.cm-2. Here, grazing incidence XRD patterns indicate iron (grey lines) and copper (green lines). Grazing angle was 2 (red curve) and 6 degrees (blue curve), respectively. Figure 4(c/1) and (c/2) show the results of XRD taken from the same sample with deposition conditions of 2 hours deposition time in 85 à ¯Ã¢â‚¬Å¡Ã‚ °C bath and -12.5 mA.cm-2 current density.

Clear evidence of magnetite (blue lines), iron (grey lines) and copper as substrate (green lines). Grazing angle was 2 (red curve) and 6 degrees (blue curve), respectively. Figure 4(c/2) demonstrates grazing incidence XRD pattern of loose powder from the same sample as (c/1). Only magnetite phase (blue lines) is detected. Grazing angle was 2 degrees. The XRD results show clear evidence of magnetite if the current density does not exceed 8 mA.cm-2 cathodic current density (see Figures 4(a) and (b). Apart from that, XPS studies have also been performed after the check meeting. For integration reasons, they are demonstrated only in the Milestone 1 document. Microstructural analysis Morphology of pellets after preparation was studied by the means of SEM (scanning electron microscopy) shown in Fig. 39. The particle size is larger for the catalyst prepared by SUN. The particle size of sample prepared at IP SAS is in good agreement with the manufacturer specification and is rather homogenous in size distribution. Sample prepared at SUN is exhibiting a different size distribution ranging from very fine sub-micron particles up to particles with size increasing 50um shown in Fig. 39 and 40. As can be seen the porosity of the prepared pellets is higher for the pellet prepared at IP SAS. The grid shown in Fig. 40 is protecting the sample from being destroyed by the magnetic field in the microscope and thus contaminating the microscope system by fine magnetic dust in the pole-piece, lens and detector system. It is worth to mention that the particle size is not directly explaining the diffraction maxima broadening shown in inset in Fig. 38. This is due to the fact that the diffraction domain size is rather different than the grain size of a particle. We can surely state that the diffraction domain size is smaller in the pellet prepared at SUN rather than at IP SAS despite the observed grain-size distribution. Figure 39. SEM micrographs of catalysts prepared by SUN (left) and IP SAS (right) Figure 40. Low magnification micrographs of catalyst prepared by SUN (left) and IP SAS (right) Micrographs from the CERTH pellets (Figure 41) illustrate a clear evidence of necks, responsible for the significant reduction of temperature. Figure 41. Micrographs of the CERTH pellets, illustrating the presence of micro-necks, responsible for the improvement of the electric and mechanical properties Concerning the thin film catalysts, SEM analysis was performed. Figure 3 demonstrates 4 different SEM-images of the prepared samples. Fig 3(a) was taken on a sample prepared in 300 s deposition period in 60 °C bath with -7.5 mA cm-2 current density, and the nominal thickness was 2.24 ÃŽÂ ¼m. In Fig 3(b) can be seen the morphology of the sample prepared in 300 s at 70 °C with-5 mA cm-2 current densitywith nominal thickness of 23.55 ÃŽÂ ¼m. Fig 3(c) shows the SEM-result of the sample deposited with the same bath temperature and current density as 3(b) but extended deposition time: Άt = 900 s (dn = 30.28 ÃŽÂ ¼m). Fig 3(d) represents the SEM-image of the sample prepared in the highest bath temperature 90 °C with 5 min deposition time, -7.5 mA cm-2 current density (dn = 4.42 ÃŽÂ ¼m). The SEM-images clearly show the structural changes by increasing the bath-temperature. Filamentous deposit structure has been observed at 90 à ¯Ã¢â‚¬Å¡Ã‚ °C. Due to the galvanostatic deposition mode the potential values have been not recorded. For better understanding of the structural formations potentiostatic deposition mode should be done. Figure 3. SEM-images of the electrodeposited iron-oxide samples with different deposition parameters (a) Άt=300 s,T= 60 °C, j= -7.5 mA cm-2 at 30000X magnification (b) Άt=300 s, T= 70 °C, j = -5 mA cm-2 at 15 000X magnification(c) Άt=900 s, T= 70 °C, j= -5 mA cm-2at 10000X magnification (d) Άt=300 s, T= 90 °C, j= -7.5 mA cm-2 at 10000X magnification. Concerning nano-foam, due to the fact that the experiments were done in the close past the characterization of the prepared nanostructures was done only by scanning electron microscope. Figure 5 demonstrates the first promising results of the electrochemical deposition of iron-based 3D structures by using hydrogen generation on the surface as a negative template. Such a structure was a result of applying -0.375 A.cm-2 and more negative current density, namely -1 A.cm-2 with different depositing times. Fig 5(a) to Fig 5 (c) represents a possible building process of the 3D networks with pore size range in 2-6 ÃŽÂ ¼m. Other type of deposit can be observed at Fig 5(d) to Fig 5(e) with numerous dendrites along the pore-sides by using current density -0.375 A.cm-2 with different deposition times. The formation of porous layer is not so obvious like in the previous case, but the size of pores are close in the same range than the pores formed at -1 A.cm-2.

Unintended Results :: Free Essay Writer

Unintended Results Almost everyone looks with disfavor on slums. In certain areas of any city, one sees housing conditions that are distressing to say the least. Several families may be using the same bath and toilet facilities. Two or more families may be living in the same apartment. The buildings and apartments may be in various states of disrepair. Why do people live in them? Usually these are as much as lower-income families can afford. Some people think that this situation should be changed. They could not agree with the fact that so many families, of three people with one employed, cannot afford at least one-bedroom-apartment, and with time they urged the government to change this situation and to take control over the rent prices. According to Ansel Sharp, â€Å"In the United States, following World War II, numerous cities elected to continue rent controls established during the war† (68). The main purpose of rent control is to support lower-income residents. The most well known example of such control is undoubtedly that of New York City, which has some of the strictest rent control in the country. By analyzing the actual effect of the controls, we certainly could conclude that the local government should abandon rent controls in New York City because market tends to react in ways that offset the intended impact of that action. Such control may involve consequences that are clearly unintended. The first unintended problem generated by the rent control is housing shortage. In other words, the demand for rent-controlled apartments overcomes the surplus. That is why so many individuals and even families are forced to share the same apartment. Many young adults encounter difficulty finding an apartment when they decide to leave the family home and to start their independent lives. The chance of finding a job in a big city is greater than in a small town. That is why so many people tend to live in New York City. In most cases, searches for rents are unsuccessful. Ansel Sharp writes, â€Å"Today in New York City, for example, it remains popular for those seeking rent-controlled housing to daily scan the obituaries looking for recently freed-up space† (68). Of course, it was not the original intention of the local government but this is the inevitable outcome of price control. Secondly, the price control in New York City fails to satisfy the needs of those who are supposed to benefit from it.

Mobile phones: blessing or curse? Essay

Nowadays mobile phones are everywhere: their bleeping ringtones go off behind you in the train; gormless-looking zombies stand around on the street â€Å"texting† illiterate messages to each other, while even children see them as an indispensable accessory. Clearly, mobile phones have come to be a normal and accepted part of most people’s lives, but does this necessarily mean they are a boon? I would say that while mobiles are potentially helpful in some situations, they generally have an adverse effect on one’s quality of life. The strongest argument for owning a mobile phone is that it can prove useful in an emergency or make you feel secure when walking down a dark street, for example. However, you should not forget that mobiles actually cause emergencies when people drive and talk simultaneously, and get into accidents. Furthermore, mobiles are one of the items muggers are most interested in, which means that carrying a mobile actually increases your chances of being attacked. see more:mobile boon or bane essay On the face of things, mobiles make life more convenient. They allow you to be much more flexible or spontaneous when making arrangements with friends, so that you can ring ahead, for example, if your train has come to a standstill. They also mean that you can stay in touch with work colleagues even when you are travelling and do not have access to a landline. There is a flipside to these arguments though. If people can be more spontaneous then they are more likely to wriggle out of arrangements, or let others know at the last minute, which can be far from convenient. Moreover, if you are always contactable, particularly by people from work, then you are enslaved in a sense. Employers are able to encroach on your leisure time and make demands of you, wherever you happen to be. Mobile phones are also anti-social in some ways, and encourage unpleasant behaviour. We have all heard the loud salespeople on trains boasting about their latest deal, or passengers who broadcast the finer details of their tedious social life. Equally rude are friends who start texting someone else while you are in the middle of a conversation with them.

Greece World War II paper essays

Greece World War II paper essays The Greek populace desired to stay out of the war in 1940. They did not have a very strong government. At the time it was a monarchal parliament under King Paul II. General Ioannis Metaxas was allowed to function as a dictator under the auspices of the king. Metaxas was well known as a general, and was able to strengthen Greece against the foreign threat that Italy and Germany posed. Metaxas became somewhat like Adolf Hitler or Bennito Mussolini. He dissolved parliament, declared a state of emergency, abolished trade unions and political parties, made strikes illegal, arrested political opponents, and censored the press. Metaxas was violently anti-communist. He exiled and even tortured communist citizens. After Metaxas death in 1941, a new leader was sought after to rebuild Greece. After the Germans vacated Greece in their slow withdrawal back to Germany, Greece became very unstable politically. The next leader to help unify and restructure Greece was Georgios Papandreou. Papandreou was elected as the Prime Minister and was very republican in his policies. The ensuing instability of the country led many to doubt Papandreou and his abilities. This eventually led to a civil war. This Greek Civil War (1945-1949) was fought mainly by communist leftists against republican rightists. Britain was involved in the beginning stages of the Civil War, but had to transfer the responsibility to the United States when it became too expensive. The United States was very helpful to Greece by giving four hundred million dollars in aid. This aid was a result of the Truman Doctrine. President Harry Truman designed what is called the Truman Doctrine as a way to thwart communism from spreading. The basic idea was to aid countries that were on the verge of switching to communism by giving them enough money to reestablish democracy to the country. Greece came close to being taken over by commu ...

ACT Study Guide Schedule and Plan for One Year or More

SAT / ACT Study Guide Schedule and Plan for One Year or More SAT / ACT Prep Online Guides and Tips You're serious about studying for the SAT. You have a year or more to study, and you want to put a real effort into it. Is studying this much worth it? What are the payoffs? And most importantly, what's the best way to study for the SAT / ACT on the year-or-more level? This post answers those questions! First, let's get a couple of important questions out of the way. Is Studying for a Year or More Worth It? Who Should Use This Guide? The short answer: yes, it's absolutely worth it. We know from recent studies that a 105-point increase on your SAT score (equivalently, 1.5 points on your ACT score) doubles your odds of getting into a given college. If you had a 10% chance of getting into Harvard before, it increases your chances to around 20%. And a 105 point increase can be obtained in a few dozen hours. This means that even if you're studying 100 hours for the SAT / ACT, those 100 hours are doing much more to increase your chance of getting into college than, say, sports or clubs. A study schedule of a year or more is definitely worth it for students who care about getting into the best colleges. How Many Hours Do I Need? How Far Ahead of Time Should I Start? If you're starting your studying a year or more before you take the test, plan to spend at least a hundred hours or more. As this SAT / ACT study schedule planner suggests, you don't want to study too few hours when you start far ahead. You should also begin studying so that you aim to take the test junior year fall (I'll explain more below). If you're planning a year to study, start during the winter or spring of your sophomore year. If you're on the more aggressive schedule of studying for a couple of years, you want to get started at the end of freshman year. Want to improve your SAT score by 160 points or more? We've put our best advice into a single guide. These are the 5 strategies you MUST be using to have a shot at improving your score. Download this free SAT guide now: Why Aim to Take SAT / ACT in the Fall of Junior Year? Many students aim to take the SAT / ACT junior spring or senior fall. But as an advanced student, if you really care about the SAT / ACT, your goal is to optimize everything about your studying. Optimizing the test date means taking it early. Why take the SAT / ACT so early? Because you want buffer space in between tests. If you don't do well junior fall, you'll still have two more chances junior spring (March and May for the SAT, February and April for the ACT) and won't have to run into summer after junior year and senior fall for testing. This is a huge advantage because you'll have all that time to focus on applying to college. And trust me, from my personal experience, you'll need that time. Think about it this way: what's the harm in taking the tests one month earlier than necessary? Okay, you stress one month earlier, and maybe you take the test with one less month of education. This is really not a large loss. What's the harm in taking it one month later than necessary? Last minute application scrambling, prep courses, and tons of stress. Take the safe bet: aim to take the tests junior fall. The First Step Okay, so you're aiming to test in junior fall, and you have around a year or more - this puts you at sophomore year or younger (if not, follow our guides for more moderate studiers). If you're starting earlier, just stretch the dates in this guide out evenly, like a rubber band. September of Sophomore Year The first thing you want to do is take two practice SAT / ACTs. Use real SATs or real ACTs. The first SAT / ACT you take, do not time yourself. You can break it into multiple pieces. Focus on readingall the instructions and the fine print. Also, focus on understanding the question and not the time pressure. If you've already taken a few SAT / ACTs in the past, you can skip this first test. Reflect on the main features of the test. Are there strategies you can already see without being told? What do you think are some tricks you can use to solve questions? (If you're using PrepScholar, we tell you this automatically). After this, take the test a second time, but follow the timer strictly. Then reflect on how time pressure changes things, and what you must do to counter this. With this second test, you also have a sense of what your mistakes are. For each mistake, write down two reasons you made it, like "carelessness" or "didn't know quadratic equation." Then, tally up the reasons and brainstorm ways to study for them. (If you're using PrepScholar, this tally analysis will be done for you automatically). These two tests will also prepare you well for the PSAT, which happens in October of sophomore year (see the PSAT timeline here). November of Sophomore Year You now have a list of major errors and how to study for them. For example, you might find yourself forgetting grammar rules, and so you'll spend 10 hours memorizing the most commonly tested grammar rules on the SAT. Or you might find that you don't know quadratic equations, and spend 10 hours reviewing them. You'll want to prioritize your content issues first. Content issues are those with fundamental knowledge of math, reading, writing, science, and so forth. These are things like what subject verb agreement is, trapezoids and their properties, and so on. Content issues are the hardest to forget, so studying early has an advantage. These issues are also the most the scalable: even if you dump a lot of time into fundamental content, you'll continue to improve as you know more of it. In fact, if you are scoring under a 1330 on the SAT or a 30 on the ACT, most of your gap is simply due to missing fundamental content. So make sure your foundations are strong. When exactly to take the next step depends on both your time budget and how much fundamental content is missing. If you're scoring, say, 1000 on the SAT or 18 on the ACT, and are budgeting over 200 hours, then the above steps should really be started earlier. The schedule here assumes you're studying 100 hours and already have a 1330 on your SAT / 30 on your ACT for the next step. March of Sophomore Year At this point, you want to shift towards strategy. Repeat the September analysis: do a timed test and see which questions are losing you points. However, this time notice where you're going wrong with strategy and test tactics instead of content. Notice when you run out of time, or make a careless mistake. Notice if you've rushed too much in one section versus another. Now come up with a few ideas to attack your strategic flaws (or if you're using PrepScholar, we come up with these strategies for you). Test out your plan by doing a few sections at a time. Do these new strategies you've thought up work? Iterate on these strategies, and repeat until you get your strategy down. At this point, ask yourself, are you getting the score you want for your school? If so, you can take it a bit easier (but still continue on). Otherwise, consider budgeting more time for studying. Bonus: Want to get a perfect SAT or ACT score? Read our famous guide on how to score a perfect 1600 on the SAT, or a perfect 36 on the ACT. You'll learn top strategies from the country's leading expert on the SAT/ACT, Allen Cheng, a Harvard grad and perfect scorer. No matter your level, you'll find useful advice here - this strategy guide has been read by over 500,000 people. Read the 1600 SAT guide or 36 ACT guide today and start improving your score. Summer before Junior Year This is Round Two of your studying. Repeat the September to March process: find more fundamental content weaknesses, and then look again for strategic weaknesses. Why split the process into two rounds? First, it increases your creativity - you may come up with strategies the second time around that you missed the first time around. Also, the strategies you use in the end will depend highly on your final performance. If you're scoring in the 800/1600 range on the SAT, skipping questions is key. If you're scoring 1270/1600, you can barely afford to skip any questions. By criss-crossing your studying this way, you get a better idea of your final score earlier on. Fall of Junior Year Sign up to take the first SAT or ACT of the year, usually August or September, respectively. Make sure you have a strong final week leading up to the test date. Before you take the test, estimate yourexpected "interquartile range." Suppose you expect there's a 75% chance you'll do better than a 900, and a 25% chance you'll do better than a 1000. Then your interquartile range is 900-1000. The Rest of Junior Year Take the SAT or ACT and then see what your score is. On your first test, if you score lower than the top of your interquartile range, plan to take it again in two months (likely December), following a shortened version of the study plan from the summer before your junior year. If your second score is less than the middle of your interquartile range, try once more in another 2-3 months, likely in February or March. Finally, if your third score is less than the bottom end of your expected interquartile range, try one last time, likely in June. Remember, taking the SAT / ACT more often is generally better for you, especially if you're scoring lower than you expected! Conclusion The above guide is a comprehensive way to study well for the ACT or SAT given 100 hours and 1 year or more of study time. The main theme is tallying up your mistakes and coming up with strategies to focus on them.

Developing A Marketing Plan for a New Product Essay

Developing A Marketing Plan for a New Product - Essay Example Overseas we also not only have the same competitors we have here, but other local competitors, such as the great candy makers in Switzerland for example. All of these factors have to be taken into consideration. Especially important is the local ideals of a region when running advertisement, as we need to be sure to not run an ad that could be considered offensive in another country. Of course our produce is very tangible, and we hope to be short lived. We are not intending people to buy our product and hold on to them, we want them to eat them so they in turn come back to buy more. We would hope for an as much as possibly purchase, similar to the candy isle you see here. Then people would buy them whenever they caught their eye, and would be instantly attracted to them. We also need to totally market our product as different and more healthy than other alternatives. This is key to success in the important demographics that we need in order to clench success for our company. Once we factor in cost and demand, we will hopefully be able to find a stable price. We do not want price to high or to low, or we may find demand fluctuating to much for our needs. Our objective is to be as successful as possible, but we may need to take initial losses to do that.

Market Analysis Research Paper Example | Topics and Well Written Essays - 1250 words

Market Analysis - Research Paper Example Minus any extra licenses, Galveston may trade beer and wine, irrespective of the source, to customers for consumption at a legitimate public eating zone. It usually takes place on the producer’s licensed premises or at a real eating zone adjoining to the company’s licensed merchandise. Wine differs from the types of grapes used and the seasoning done during the processing. The flavor habitually comes from the nature of the container used in the wine manufacture process, typically oak material. According to Geraci (451), there are three core categorizations of wine, counting the red, white and blush wine types. Categorically, white wines are manufactured from bright-colored grapes and are commonly lighter in flavor than red and blush wines respectively. On the other hand, red wines are characteristically formed from darker grapes, and their stalks are mixed together in the crushing process. Wine drinking and familiarity wine as considered as part of the wealthy and learned civilization is a reality. Despite its alcoholic aspect, wine producers recurrently try to promote wine as part of everyday dining through advertisements (Geraci 460). The underlying reason would be to make it enjoyable for individuals who can manage to pay for the better-quality things in life.  The last step in wine production involves getting the product conveyed to the customer through a given means of transport. In case the distribution channels face ignorance, there can be a substantial impact on a wine corporation. Competence, product value, the cost of the process and on the view it holds in the minds of suppliers and customers would be real impacts felt than imagined. Several distributions from the wineries have stopped private, leased, or rented trucking corporations. According to Department of Alcoholic Beverage Control (1), youngsters are tolerable to partake of the
