Tradegy Essay Example For Students

Tradegy Essay As Aristotle says, Tragedy is an imitation not of human beings but of action, life, happiness, and unhappiness. Very few of the great tragedies could possibly be based in reality. For instance, how likely is it that a great king once discovered that he killed his father and married his mother in real life. The purpose of this tragedy is to show the downfall of a great leader. This includes action, life, happiness, and unhappiness just as Aristotle says. Who would want to read something about a person that bad things happen to if the reader does not understand why it happens and the reason for the reaction?Another example would be Antigone. It was not written to watch a woman bury her brother and have everyone around her die. The purpose is to gain insight on the human way of life. The story tells of duty and honor, not of death and politics. We are made to care about not necessarily Antigone herself, but her cause. That is what makes a great tragedy.

Biotechnology and genetic engineering Essays

Biotechnology and genetic engineering Essays Biotechnology and genetic engineering Paper Biotechnology and genetic engineering Paper 1 Biotechnology and genetic engineering of both plants and animals raise a lot of issues from concerned groups such as the Green Peace and Friends of the Earth environmental activists. Biotechnology is â€Å"defined as the application of scientific and engineering principles to manipulate life forms to provide desirable products for human use (Lewis 70) This definition is applicable to the proponents but to those who oppose, they consider this process as the cause of the destruction of nature. 2. aBiotechnology involves processes of manipulating and modifying the genes of an organism to suit the desired structure of the genes such as greater yield quality, tastier character, immune resistance to pests and weeds and a lot of other qualities that may be useful for humans. This is not entirely different from selective breeding that improves the breeds of an organism but the latter is more of a natural process and does not involve very advance modification processs. Another difference is the time needed in completing the process. Selctiive breeding involves programs to choose the traits to be improved while the genetically modified or genetically engineered organisms are, as the names suggest, forcedly modified and engineered in their genes. â€Å"Scientists at Beltsville, Maryland, created a boar by injecting cattle genes into fertilized embryos of a pig and implanting the embryos in the womb of a surrogate cow(Krimsky, 1991, p. 55) is an example of modifying the genes. This is not possible in selective breeding because a cow cannot actually give birth to a pig naturally. 2. b The good side and potential advantages of biotechnology is that it causes the genetically engineered food crops to yield more which is beneficial to farmers and to the world that needs food. It also makes the food to taste better and fortified with induced vitamins and nutrients in it, while causing the crops to have resistance to pests and weeds reducing the use of expensive and environmentally harsh chemicals. 2c On the side of those environment activists and ethically concerned groups, they argue that biotechnology causes a lot of troubles in the long-run and even in the present. The case of seed patenting letting farmers suffer is one among these many issues. Another is on the possibility of causing immunities to weeds and pests in the long run and they would not be able to be eliminated due to these immunities caused by chemicals that are paired with genetically engineered crops. Another issue is on the loss of diversity in the environment, genetic erosion, environment problems that may be caused by genetic engineered cropping in the future such as soil erosion and many more.

Japanese Immigrant Essay Example | Topics and Well Written Essays - 2500 words

Japanese Immigrant - Essay Example As per the Census 2000, the Japanese Americans comprise for 7.77% of the Asian-American population and 0.28% of the US population. Like other ethnic minorities, the Japanese too had to struggle to establish themselves in the United States economically, educationally, socially, religiously and politically. This paper will discuss the patterns of Japanese immigration, the developments, the history and the changes that took place over the years. It will also discuss the reasons for Japanese immigration to America and their initial experience. Among the first to arrive from Japan in 1869 were the settlers with The Wakamatsu Tea and Silk Farm Colony, according to the Brown Foundation Journal (2000). They carried with them mulberry trees, silk cocoons, tea plants, and bamboo roots. COHORTS (1999), a publication of the Stanford Geriatric Education Center, describes that thousands of young Japanese male laborers came from Hawaii and Japan in 1885 to work on railroads, to pick fruit and vegetables for canneries, or to work in industries such as logging, mining, and meatpacking. ParkNet (2004) further clarifies that the first group arrived under the leadership of John Schnell. Initially, a group of Japanese were picked up from the streets of Yokohama and shipped to Hawaii. These were found to be unsatisfactory after which they developed systematic recruitment process. Based on the Census 1870, ParkNet quotes that out of 55 Japanese in the United States, 33 were in California and 22 in Gold Hill. The 1880 Census showed 148 Japan ese in the United States including 48 in California. According to ParkNet these could have been either students or those who had left Japan illegally as the laborers were not allowed to leave their country until after 1884. In 1884, the Japanese government and the Hawaiian sugar plantations signed an agreement to allow labor migration. In 1890, 2038 Japanese resided in the United States out of which 1114 lived in California. ThinkQuest, an

Advertising Campaing for Natural Viagra Essay Example | Topics and Well Written Essays - 750 words

Advertising Campaing for Natural Viagra - Essay Example As the study highlights NaV (to be pronounced as ‘Navy’) is the product of a unique formula combining the efforts of doctors and experts in the field of pant sciences. Formulation of a new concentrate from the rarely gifted plants and fruits of the nature is now outstanding with its ability to cure the problems like lack of erection and disability to attain the confident size. Unlike other products of the similar kind, ‘Natural Viagra’ poses no threat of a cardiac arrest. Our enterprise has a favorite note for Australian culture which arranges for the free sex as well as sexuality oriented sports. The magnitude of the industry is much intense in Australia when compared to other countries in the world. Majority of the studies revealed the fear of performance failure caused men to withdraw from sex during their age post 60s. It is therefore noticed that Australia is a wide market for launching this product. Industries are now focusing on the introduction of ne w brands of products in the enhancement lines with a view to target the consumers deprived of sex. As a result of the legal advantages, there is a substantial rise in the production and consumption of such drugs in the recent years with a tendency to continue the growth over the next few decades in Australia. NaV must be considered the best choice for introduction in Australia as the country hosts a cultural mix from various parts of the world population which makes the most of the sales. As far as the competitors are concerned, Australian markets are the safe haven for them. Immediate competitors are the distributers of Viagra ® but other locally branded products may also pose considerable amount of contest. This paper outlines that most of them attract men with catchy taglines and attractive strategies of guarantees of money return on dissatisfaction. They substantiate the growth of sales volume through visual and print media advertisements apart from sales-counter counseling to customers. Recently, they started alerting the targets with pop-ups in their web pages through search engines and socialize websites. Consumer psychology related to the use of these drugs is a matter of socially biased views. Most of the customers are old-aged individuals who do not want to identify themselves as a favorite of their sexual urges. A majority of them conceal their feelings owing to the expectations of their reputation in the society. On most occasions, they fail to make the purchase themselves and want the distributors to provide them personalized sales of it. Since the product has the implications of social identity, majority of the customers want the marketplace to be changed from open sales cou nters to reliably privatized modes of distribution. II The target market for NaV has been fixed as men of the age group between 55 and 75 who have sustainable enthusiasm to enjoy sex. Since most of them are expected to bear the threat of pulmonary and pancreatic issues, this product guarantees absolute safety against diabetes and cardiac disorders.

EU law Essay Example | Topics and Well Written Essays - 1500 words

EU law - Essay Example This brief analysis will work to give counsel to the two women, Ame and Bridget, which are presented in the given case assignment as well as provide them with the legal knowledge and constraints that pertain to their individual cases under domestic and European Commission jurisdictions. Likewise, the analysis will attempt to call out specific portions of the European Commission Directive that aptly apply to their given discrimination complaints. Far from being equal, both cases present us with unique constraints and drawbacks which will be elaborated upon and inference/parallels will be drawn to similar cases that have proceeded these and defined a type of precedent for such actions in the not so distant past. Case 1: Ame’s Claim of Age-Discrimination at the State Health Service of Waltaria With respect to discrimination based upon age, 2000/78/EC article 11 is very specific: â€Å"Discrimination based on religion or belief, disability, age or sexual orientation may undermine the achievement of the objectives of the EC Treaty, in particular the attainment of a high level of employment and social protection, raising the standard of living and the quality of life, economic and social cohesion and solidarity, and the free movement of persons† (emphasis provided) (EC 2000/78). As such, the law specifically speaks to the fact that Ame could not justifiably or legally been terminated based upon her age alone. However, there are two complicating factors to this interpretation which will be discussed at greater length; however, it is worth repeating that based upon the information Ame has provided , there is grounds for a court case with respect to this particular termination. Firstly, one must be aware of what lengths the defendant will be likely to go to in order to defend the legality and rightfulness of their action. This is not to discourage Ame from seeking legal action on this matter; instead, it is to make her aware that the defendant will likely attempt to invoke article 25 of 2000/78/EC which states: â€Å"The prohibition of age discrimination is an essential part of meeting the aims set out in the Employment Guidelines and encouraging diversity in the workforce. However, differences in treatment in connection with age may be justified under certain circumstances and therefore require specific provisions which may vary in accordance with the situation in Member States. It is therefore essential to distinguish between differences in treatment which are justified, in particular by legitimate employment policy, labour market and vocational training objectives, and discrimination which must be prohibited† (EC 2000/78). To what degree the defense will attempt to invoke this and to what level they have supporting documentation that shows this was their actual goal is of course unknown; however, Ame should be aware that this is a likely tactic. Secondly, due to the lack of material evidence (Ame only has overheard a discus sion by certain elements in management. Her particular case is without strong and relevant proof (i.e. a number of other employees terminated at the same time and of the same demographic group) she will have difficulty providing a solid case within the court system. Although it is clear from her letter that

Novel Elliptic-function Low-pass Filter (LPF)

Novel Elliptic-function Low-pass Filter (LPF) Performance of microstrip low pass filter with stub loaded Electromagnetic Band Gap ground plane Mariselvam V, Raju S Abstract A novel elliptic-function low-pass filter (LPF) is Presented, which consists of a Electromagnetic band gap on the ground plane. The Electromagnetic band gap provides the required wideband attenuation in stop band, while the slot provides steep transition from pass band to stop band. A 5.4 GHz five-pole LPF is developed and experimental results show that it has a sharp cutoff frequency response. The measured pass band insertion-loss is below 0.4 dB, and the rejection band over 15 dB is from 5.425 GHz to 8.25 GHz, Which increases from 2.95 GHz.      Keywords:  Defected ground structure (DGS), elliptic-function filter, low-pass filter (LPF). 1. INTRODUCTION Recently, defected ground structure (DGS) has become one of the most interesting areas of research in microwave and millimeter wave Applications [1]. It could be widely used in microwave circuit design such as power divider, power amplifier and especially in filter design [1–9]. Low pass filters (LPF) design require that both in-band and out-band performances should be: low loss, high selectivity, high rejection, and wide spurious free frequency ranges. Many novel types of microstrip filters have been proposed and designed. Periodic or non-periodic DGS are realized by etching a slot in the backside metallic ground plane. The etched slot disturbs effectively the current distribution in the ground plane of microstrip line and the results in resonant characteristics [2, 3]. IT is well known that typical properties of low-pass filters (LPFs) can be obtained by adding periodic structures to transmission lines. The representative periodic structures for planar transmission lines and/or microwave circuits are photonic band gap (PBG) and defected ground structure (DGS) [4, 5]. The PBG has been known as a popular periodic structure for planar transmission lines. However, drawbacks of PBGs have been also discussed as follows. 1) A large area is needed because a number of periodic patterns should be adopted. 2) It is obscure to define the unit element, and difficult to extract the equivalent-circuit elements for the PBG unit element. 3) Therefore, it is very restricted to extend its practical application to microwave circuits. To the contrary, one can easily define the unit element of the DGS and model the equivalent circuit. In addition, since only a few DGS elements show the typical properties of periodic structures, the resultant circuit size becomes relatively small. Furthermore, the structure of the DGS is simple and it is easy to design the DGS pattern. For these reasons, since [4] has introduced the structure and called it a DGS for the first time, the DGS has been extensively applied to design microwave circuits such as filters, power dividers, couplers, amplifiers, oscillators, and so on [1], [6]–[12]. There is much previous research about the characteristics of LPFs having periodic structures on microstrip or Coplanar waveguide (CPW) transmission lines [13]–[16] However most of them are not analytical because they mainly depend on electromagnetic (EM) simulations to design LPFs and predict circuit performances. To the contrary, in the design of LPFs using DGSs including this study, all design steps are based on theories and reasonable explanations as follows. The equivalent-circuit elements of the DGS is extracted and used for replacing the series inductances in the LPF Prototype circuit. The LPF is composed of the extracted equivalent lumped Elements, thus, it is an ideal LPF, is designed, and is compared to the realized LPF using the DGS practically. Two methods to design a three-pole LPF using the DGS has been proposed in [1] and [6]. In these papers, the sizes of two DGS patterns in the LPF were exactly the same because two inductances in the three-pole â€Å"L1 (series) C2 (shunt) L3 (series)† prototype LPF are identical. In [6], discontinuity elements such as tee- or cross-junctions were adopted to connect open stubs to realize the shunt capacitance. However, in the three-pole LPF proposed in [1], there are no junction elements, thin transmission lines for high impedance, or open stubs. In addition, the width of the transmission-line elements in the LPF has been remarkably broadened. Thus, advantages such as compact design and error-robust realization fabricating the layout have been obtained. However, in order to design -stage LPFs using the DGS, e.g., a five-stage like â€Å"L1 (series) C2 (shunt) L3 (series) C4 (shunt) L5 (series),† two different dimensions of the DGS have to be adopted because L3 is no t equal to L1=L5, although. In order to select the proper dimension of the DGS for L3 careful consideration based on filter theories, extracted equivalent- circuit elements of various DGS dimensions, and some related topics of transmission lines should be taken. The size of the DGS for L3 is determined by accurate curve-fitting results for equivalent-circuit elements to correspond exactly to the required inductance. In addition, the length of transmission-line elements between DGS patterns is determined through the consideration for the equivalent capacitance and additional parasitic inductance, as well as the required shunt capacitances in the prototype LPF. Therefore, a design of a five-pole DGS-LPF requires many more complex steps than the previous three-pole DGS-LPF shown in [1] and [6]. Thus, the goal of this paper is to propose a new technique to design an -pole LPF having (â€Å"DGS-LPF†), and to generalize the previous design method for N>5 using different sizes of DG S patterns. For this purpose, modeling for the equivalent circuit of the DGS, a curve fitting for determining the required different sizes of the Fig.1 Top view of the Microstrip line with a DGS pattern and its dimensions in mm Fig.1a. Bottom view of the Microstrip line with a DGS pattern and its dimensions in mm DGS that reflects the inductance values in the prototype LPF and a practical design example will be successively discussed. In order to show the validity of the proposed method, a five pole DGS-LPF, as an example, is designed and measured in this paper. The five-pole DGS-LPF has a much wider microstrip line than conventional microstrip LPFs, and does not include high-impedance lines, which have been essentially required in conventional design. The series inductances in the prototype LPF are realized by DGSs, while the shunt capacitances are realized by the widely compensated transmission line. Therefore, no discontinuity elements such as tee- or cross-junction for connecting open stubs are required because there are no stubs in the DGS-LPF. 2. DGS PATTERN AND MODELING FOR THE EQUIVALENT CIRCUIT Fig. 1and 1a shows a microstrip line having a dumb-bell DGS and its -parameters from an EM simulation. Two elliptical defected areas and one connecting slot correspond to the equivalently added inductance (L) and capacitance(C), respectively. Accordingly, a resonance occurs at a certain frequency because of the parallel L–C circuit. Inversely, it is intuitively known that the equivalent circuit includes a pair of parallel inductor– capacitor from the resonant phenomenon in the -parameter. This means the microstrip line having the DGS does not have all-pass characteristics, but restricted pass band properties. Fig.2. Equivalent circuit of the microstrip line with unit DGS using ADS In addition, slow-wave characteristics are observed due to the added– components of the DGS [3], [5], [9]. The defected areas can be realized by not only ellipse, but also other geometries such as triangle, circle, hexagon, octagon, spiral, and so on. It is very clear that the resonant frequency (wo) of the DGS and 3-dB cutoff frequency (wc 3dB) exist as shown in Fig. 1.The equivalent – circuit of the DGS can be extracted because this kind of electrical characteristic is observed from a typical L –C parallel resonant circuit. The equivalent circuit of the DGS and one-pole Butterworth prototype of the LPF are presented the DGS in Fig. 2. The equivalent L– C elements are calculated by (1–3) because two reactance values of Fig. 2(a) must be equal at wc 3dB as follows XLc= (1) XL = ωZo g1 (2) XLc | ω= ωc, (3) Where w'(=1), g1 (=2) and Zo (=50ÃŽ ©) are the normalized 3-dB cutoff frequency, element value of one-pole Butterworth prototype LPF, and port impedance, respectively, and wo = (1/√ Lk1Ck1). The calculated L2and c2 of the DGS shown in Fig. 2 are 3.2 nH and 0.8194 pF, respectively. Fig. 3 shows an excellent agreement between the previous -parameters shown in Fig. 1 and the new ones calculated using Lk1and ck1. Advanced Design System (ADS), a circuit simulator from Agilent Technologies, has been used for the calculation. This agreement means that the modeling technique is valid in extracting the equivalent-circuit elements. It should be noted that this is one of the great advantages of DGS because it is possible to define the unit element of the DGS and to establish the equivalent circuit of it, while the conventional Planar transmission lines with a periodic structure such as a PBG have difficulty in defining the unit element and to extract the modeled circuit element. 2.1 DESIGN OF THE FIVE POLE LOWPASS FILTER A. Prototype LPF and Adoption of DGS The method to design a five-pole LPF using the DGS is discussed here. Fig. 3 depicts the prototype circuit of a five-pole LPF. Here gi (i=0, 1, 2, 3, 4, 5, 6), represent the normalized element values of a Chebyshev prototype LPF for the given ripple [17]. According to the design theory of filters, in order to transform the prototype LPF to the LPF composed of lumped elements, the values of L1,C2,L3,C4 and L5can be determined owing to the impedance and Fig.3. Five-pole Chebyshev prototype LPF with Elliptic DGS Fig.3a. Equality of a series inductor to an LC parallel circuit frequency scaling rules expressed in (4)–(6). Here, ωc means the Cutoff frequency of the LPF L1 = = = L4 (4) L3 = (5) C2 = = C4 (6) Fig.4. Performance of the designed five pole LPF using ADS Fig.5. Performance of the designed five pole LPF using CST 2.2 PERFORMANCE OF THE DESIGNED DGS-LPF FIG. 6 shows the measured S-parameters of the designed DGS-LPF, as compared with the theoretical performance (circuit simulation) and the EM simulation by CST-MWS. As shown, the measurement result agrees with the EM simulation very well. The designed elliptical function DGS-LPF exhibits a much shaper transition knee than the Chebyshev one reported in [5]. Its transition bandwidth from 1 to 20 dB attenuation is only 0.45 GHz. The measured pass band insertion loss is less than 0.3 dB. The stop bandwidth corresponding to 15dB rejection is from 2.95 to 8.25 GHz. The total length of the designed DGS-LPF is 17 mm, and compared with the LPF reported in [5], it is reduced about 40.88% and compared with the LPF reported in [6] it is reduced about 14.66%. Fig.6. Measured result of the designed five pole LPF using Agilent Network analyzer N5230A 3. PERFORMANCE OF THE PROPOSED DGS LOWPASS FILTER Fig.7. Top view of the Microstrip line and its dimensions in mm Fig.7a. Bottom view of the Microstrip line and its dimensions in mm The proposed five-pole DGS-LPF has a much wider microstrip line than conventional microstrip LPFs, and does not include high-impedance lines, which have been essentially required in conventional design. The series inductances in the prototype LPF are realized by DGSs, while the shunt capacitances are realized by the widely compensated transmission line. A stub like elements which gives a inductance effect is introduced in the proposed DGS-LPF. DGS combined with microstrip line causes a resonant character of the structure transmission with a resonant frequency controllable by changing the shape and size of the slot. There is a huge evolution in terms of defected shapes: dumbbell, periodic, fractal, circular, spiral, and L shaped [12–14]. In this paper, a novel elliptic shape DGS is proposed for the LPF design. The use of elliptic shape DGS will be shown to give sharp cut off frequency response as well as a good performance in the pass band. The analysis of the dimension parameters with different dimension parameters was demonstrated as a design guide. The equivalent circuit (EC) has been extracted to characterize the proposed low-pass filter. The equivalent circuit model agrees with the field simulation results. The theoretical and measured results are presented with good agreement for LPF. The total length of the designed DGS-LPF is 15 mm, and compared with the LPF reported in [5], it is reduced about 60% and compar ed with the LPF reported in [6] it is reduced about 29%, the pass band increases up to 5.425 GHz from 2.95 GHz and the stop bandwidth corresponding to 15dB rejection is from 5.425 GHz which is suitable for WLAN application Fig.8.

CONCLUSION This letter has presented a new LPF to obtain elliptic-function response using Dumbbell shaped DGS. The designed LPF exhibits sharp cutoff frequency response, low insertion loss, and excellent stop band performance. The proposed design procedure can be extended to arbitrary -stage LPF. In addition, its physical structure is only composed of defect and microstrip line, so it is easy to fabricate. Since this design is simple, analytical, and does not require any optimization process, this kind of equivalent circuit model of DGS and its design technology may be further applied to various microwave circuits such as low-noise amplifiers, diplexers, mixers, and so on.

Analyzing Wilbur’s Orchard Trees, January :: Wilbur Orchard Trees January Essays

Analyzing Wilbur’s Orchard Trees, January By reading one of Richard Wilbur’s poems, one can get extremely confused while trying to find the actual meaning of the poem. Someone could take the easy way out and not try to get deep down into the poem to find the real meaning, or one could investigate the poem and learn what Wilbur is trying to get across to the reader. In "Orchard Trees, January," one could pick up what Wilbur is trying to say if one takes the time to think about it. On some of his poems, though, it is nearly impossible to know what he is talking about. Only the interpretation from Wilbur himself could help one who is completely baffled by one of his poems. Authors often write their poems at the spur of the moment, and the mood that the poet is in reflects the meaning of the poem. Centenary College was lucky enough for Richard Wilbur to come to the school and explicate many of his poems. This helps in dissecting Wilbur’s poems. When reading "Orchard Trees, January," it seems to be talking about how a tree survives the harsh winter until the spring arrives, upon which it appears new and more fresh than ever before. By looking deeper into the poem, there are details that one can pull out of it, which is probably what Wilbur wants to be known. In the poem, it seems that somebody is inside his or her dwelling place looking outside at a tree. The person is marveling at how the tree can withstand the cold weather, continuous snow, and other harsh conditions that the winter brings. Witnessed throughout the days of winter by the person in the window, the tree’s bark stays strong, however the winter snow has been able to penetrate it. The tree becomes frozen, but it is strong enough to live throughout the winter until the spring relieves its suffering. When spring finally arrives, the effects of winter can no longer harm the tree. The freezing stage is gone, and the tree can give forth new life and growth in the springtime. The true meaning of this poem could only be perfectly interpreted by Wilbur, himself. In "Orchard Trees, January," it seems that the interpretation previously given above is correct, although Wilbur may have some different stress points. There probably is an even deeper meaning in this poem that Wilbur could get across, but most of the time it is up to the reader to be able to pick it out and relate it to the poem.
