The Chaco Road System - Southwestern Americas Ancient Roads

The Chaco Road System - Southwestern America's Ancient Roads One of the most captivating and interesting parts of Chaco Canyon is the Chaco Road, an arrangement of streets transmitting out from numerous Anasazi Great House locales, for example, Pueblo Bonito, Chetro Ketl and Una Vida, and driving towards little anomaly destinations and normal highlights inside and past as far as possible. Through satellite pictures and ground examinations, archeologists have distinguished at any rate eight principle streets that together run for in excess of 180 miles (ca 300 kilometers), and are in excess of 30 feet (10 meters) wide. These were uncovered into a smooth leveled surface in the bedrock or made through the evacuation of vegetation and soil. The Ancestral Puebloan (Anasazi) occupants of Chaco Canyon cut enormous slopes and flights of stairs into the precipice rock to associate the roadways on the ridgetops of the gulch to the destinations on the valley bottoms. The biggest streets, developed simultaneously the same number of the Great Houses (Pueblo II stage between AD 1000 and 1125), are: the Great North Road, the South Road, the Coyote Canyon Road, the Chacra Face Road, Ahshislepah Road, Mexican Springs Road, the West Road and the shorter Pintado-Chaco Road. Basic structures like embankments and dividers are found at times adjusted along the courses of the streets. Additionally, a few tracts of the streets lead to characteristic highlights, for example, springs, lakes, peaks and zeniths. The Great North Road The longest and generally renowned of these streets is the Great North Road. The Great North Road begins from various courses near Pueblo Bonito and Chetro Ketl. These streets meet at Pueblo Alto and from that point lead north past as far as possible. There are no networks along the streets course, aside from little, secluded structures. The Great North Road doesn't interface Chacoan people group to other significant focuses outside the gulch. Likewise, material proof of exchange along the street is scant. From an absolutely practical viewpoint, the street appears to go no place. Motivations behind the Chaco Road Archeological translations of the Chaco street framework are partitioned between a financial reason and a representative, ideological job connected to genealogical Puebloan convictions. The framework was first found toward the finish of the nineteenth century, and first uncovered and concentrated during the 1970s. Archeologists recommended that the streets primary reason for existing was to move neighborhood and outlandish products inside and outside the ravine. Somebody likewise proposed that these enormous streets were utilized to rapidly move a military from the ravine to the exception networks, a reason like the street frameworks known for the Roman domain. This keep going situation has for some time been disposed of as a result of the absence of any proof of a lasting armed force. The financial reason for the Chaco street framework is appeared by the nearness of extravagance things at Pueblo Bonito and somewhere else in the gulch. Things, for example, macaws, turquoise, marine shells, and imported vessels demonstrate the significant distance business relations Chaco had with different districts. A further recommendation is that the far reaching utilization of wood in Chacoan constructionsa asset not locally availableneeded a huge and simple transportation framework. Chaco Road Religious Significance Different archeologists think rather that the primary reason for the street framework was a strict one, giving pathways to occasional journeys and encouraging local social events for occasional functions. Besides, taking into account that a portion of these streets appear to go no place, specialists recommend that they can be linkedespecially the Great North Roadto cosmic perceptions, solstice stamping, and horticultural cycles. This strict clarification is upheld by present day Pueblo convictions about a North Road prompting their place of birthplace and along which the spirits of the dead travel. As indicated by current pueblo individuals, this street speaks to the association with the shipapu, the spot of development of the precursors. During their excursion from the shipapu to the universe of the living, the spirits stop along the street and eat the food left for them by the living. What Archeology educates us Concerning the Chaco Road Space science unquestionably assumed a significant job in Chaco culture, as it is noticeable in the north-south hub arrangement of numerous stately structures. The primary structures at Pueblo Bonito, for instance, are masterminded by this bearing and most likely filled in as focal spots for stately excursions over the scene. Inadequate centralizations of artistic parts along the North Road have been identified with a type of ceremonial exercises completed along the roadway. Segregated structures situated on the side of the road just as on the gully precipices and edge peaks have been deciphered as holy places identified with these exercises. At long last, highlights, for example, long straight scores were cut into the bedrock along specific streets which dont appear to highlight a particular heading. It has been recommended that these were a piece of journey ways followed during ceremonial functions. Archeologists concur that the motivation behind this street framework may have changed through time and that the Chaco Road framework presumably worked for both financial and ideological reasons. Its noteworthiness for paleohistory lies in the likelihood to comprehend the rich and modern social articulation of tribal Puebloan social orders.

Unquestionably, the principal vehicle they will pick the less expensive vehicle and reasonable vehicle. New Entrant has a high danger  Recession the financial will be a major danger for PROTON.

Moreover, as the firstâ national car maker they have over 20 years of experience and supported by the in excess of 1000 providers and exceptionally focused dispersed the administration and circulation way out. As monetary year ender 31 March 2006 signified, the net estimation of advantage is more than RM 5 billion while the liabilities is just about RM 2 billion. Proton had started on an undertaking with the Lotus. Gathering to improve a mixture vehicle capable of running on both gas and power and others extraordinary activities that are focusing on innovation advancement. This program direct to raise high the innovation to a level that is comparable to their worldwide opponents by making an elective vehicle for the future which gives clients less fuel utilization, decline spread and solid execution. The expansion quantities of generous request by the distinctive abroad markets were far in excess of the number delivered, the thing that matters was because of limitations in the gracefully chain. There is no questionable that interest for Proton vehicles in the abroad markets exists. All things considered, looking forward into monetary year 2007, the organization predicts a significant improvement in the quantity of Proton vehicles sold abroad. http://www.oppapers.com/expositions/Swot-Analysis-For-Proton-Holding/429480 The shortcomings of Proton Holdings Berhad PROTON was joined on 7 May 1983 with three essential national approach targets: To lead the improvement of part fabricating enterprises, to secure and update innovation and modern aptitudes inside the vehicle producing industry and to fortify the universal seriousness of Malaysias mechanical ability. The disappointment by Proton to locate a remote accomplice is an admonition signal that it is not, at this point a serious and monetarily practical element with current market circumstance and flawed administration choices that makes Proton lose cash when different discovers benefits. Subsequently, Proton Holdings Berhad needs to consider an outside association to additionally enhance its quality and administration to the purchasers. Khazanah Malaysia, the Malaysian governments speculation arm, holding about 42.74% of Proton, trailed by the Employees Provident Fund with 15.4 percent and Petronas with 7.9 percent. Value/Earnings: Not Meaningful Value/Sales: 0.3x (2/5 focuses) Value/Book: 0.4x (2/5 focuses) Value/Cash Flow: Not Meaningful TEV/Sales: 0.1x (3/5 focuses) A merger has its favorable circumstances economies of scale, showcase mastery, and so forth however a developed national vehicle organization could make numerous duplications for example item, sellers organize, merchants and so forth. Proton is thinking that its intense to trim its system of providers and merchants. National vehicle organization Proton Holdings Berhad once commanded with a dominant part share in the market. It has since not just lost that dominant part, its deals in unit terms have even dipped under that of unlisted Perusahaan Otomobil Kedua Berhad (Perodua). UMW Holdings Berhad is the greatest in the division, with a market estimation of RM5.9 billion, contrasted and Protons RM1 billion. In spite of the fact that, UMW has a significant oil and gas division, it determines a large portion of its benefits from its Toyota division, the most gainful in the business. Interestingly, Proton revealed lost RM75 million in the October December quarter a year ago. It is surpassed in advertise an incentive by Oriental Holdings Berhad (RM2.3 billion) and DRB-HICOM Berhad (RM1.4 billion), the two of which are broadened engine based gatherings. In my decision, Proton should keep on looking for key partnerships and further grow its market all around because of the end of talks with Volkswagen AG in the time of 2007. In my perspective, Proton needs to fundamentally incorporate more into the worldwide gracefully chain and the worldwide market. Fundamentally, we have not accomplished the sort of fare entrance anticipated when the organization was built up. Worldwide engine vehicle industry was experiencing a solidification and Proton ought to be a piece of this pattern. We should be a piece of the greater family such that works for us. Till date, we didn't have any explanation with respect to The Public Accounts Committee (PAC) present its report on Proton Holdings Berhads offer of Italian motorbike producer, MV Augusta to GEVI s.p.a at one euro to Parliament since Proton had obtained a 57.75 percent stake in MV Augusta in December 2004 for 70 million euro (RM367.6 million). http://wiki.answers.com/Q/What_is_the_weaknesses_of_proton_holdings_berhad Swot Analysis Of Proton Holding Berhad Initially brought about by Malaysias Prime Minister of the day, Dato Seri Mahathir Mohamad, PROTON Bhd was joined on seventh May 1983 with the point of building a national vehicle.

Curley’s Wife Free Essays

How does Steinbeck present the character of Curlers wife in Of Mice and Men? Steinbeck’s ‘Of Mice and Men’ is a poignant tale which tells of a number of disconnected, isolated characters. Curlers wife epitomises the extreme loneliness of the human condition. Although she only makes a significant appearance three times in the novel, she plays an important part both in terms of plot development and in terms of furthering the readers’ understanding of the theme of loneliness and alienation. We will write a custom essay sample on Curley’s Wife or any similar topic only for you Order Now Steinbeck uses a number of techniques to portray Curlers wife and the resulting character is fairly hard to pin down. Although Steinbeck uses a third person omniscient narrator, it is important to acknowledge that we learn of Curlers wife through a male perspective; the author/ narrator is male, as are all of the other ranch dwellers who comment on and Judge Curlers wife, potentially subtly prejudicing the reader. Curlers wife is known throughout the novel as ‘Curlers wife’ and this has a number of effects. Firstly, her lack of personal identity dehumanises her. Every other character, including Crooks, has a name. Curlers wife is consistently identified as her husband’s possession. This is a constant reminder as to the main reason that the anch workers cannot talk to her: they are anxious that Curley could take offence at any male engagement with his wife and that, because he is the boss’s son, they could lose their Jobs as a result. The name she is referred to by the narrator and by the other characters in the novel could be seen as indication of women’s inferior social status in 1930s America. Although in a letter to an actress playing Curlers wife in a stage version of ‘Of Mice and Men’, Steinbeck insists he is sympathetic to the only female character, as readers, we have to work hard to feel sympathy towards her. Through the use of the other characters’ opinions, the reader is given a biased view of Curlers wife before even meeting her. For example, Candy, who is portrayed as a trustworthy, likeable character, tells George that Curleys wife ‘gives Slim the eye’, meaning that she flirts with him, and apparently all the other men on the ranch. He finishes his piece of gossip by concluding that she is ‘a tart’. This view is echoed by other men on the ranch later in the novel, and George also decides after their initial brief meeting that Curlers wife is indeed a tramp’, ‘poison’, Jailbait’ and a ‘rat trap’. All of the men’s insults suggest that Curleys wife is sexually available to anyone. There is a sense of hypocrisy here given that almost all of the men, including Curley, frequent Susy’s place, the local brothel or ‘cathouse’. When Curlers wife first appears in the novel, supposedly looking for Curley (as she always is) in the bunkhouse, the description of her appearance may seem to support Candys opinion of her. Her heavy make-up (full, rouged lips’†¦ fingernails were red’), her overly coiffured hair-style which is mentioned every time she appears in the novel, and her choice of clothes and shoes ‘red mules, on the insteps of which were little bouquets of red ostrich feathers’) is not only incongruous with the ranch lifestyle, but also could be seen as an attempt to appear seductive. Her body language – ‘leaned back against the door frame so that ner body was thrown torward ‘ – could ce rtainly suggest that sne is physically ottering herself to the men, and her manner of speaking – ‘playfully- could be interpreted as flirtatious. However, it is significant that when she is first introduced, she is referred to as a ‘girl’ which suggests that she is young and naive. Indeed, it is implied in the ovel that she is very young. Whit refers to her as the new kid’ (although subsequently calls her a ‘100100’) and she herself retorts Whatta ya think I am, a kid? In addition, when she tells her story to Lennie, she refers to a recent incident which happened when she was fifteen. The other interesting aspect of her first appearance is that the men are alerted to her presence because the rectangle of sunshine in the doorway was cut off. Again, later on, in the barn, Steinbeck uses light in the description of Curleys wife’s dead body. The contrast is that in the first scene she locks off natural light and in the final scene, the light was growing soft’ casting an almost romantic atmosphere in the barn where Curlers wife lies, seemingly at rest. The second point here, is that Curleys wife is always appearing at doorways – of the bunkhouse or in Crooks’ room, but never managing to enter. This may be a metaphor for the fact that she is always an outsider. The only time she enters a male space and seems to make contact is Just before her death. After our first meeting with Curleys wife, it would be easy to agree with the men’s sexist view towards her. Steinbeck ontinues to make it difficult for the reader to sympathise with her in her second scene when she appears at the doorway of Crooks’ quarters. Her mannerism may be seen to be somewhat unpleasant and aggressive, ‘They left all the weak ones here’†¦ ‘An’ what am I doin’ here talking to a bunch of bindle stiffs – a nigger an’ a dum-dum and a lousy 01†² sheep – an’ likin’ it because they ain’t nobody else’. However, if we look at her actions, all the time, the only thing she is seeking is human contact. She is extremely lonely and isolated, as she tries to explain to the men: ‘Think I don’t like to alk to somebody ever’ once in a while? Think I like to stick in that house alla time? Several times she indicates that her marriage is not happy, that Curley is self- obsessed and that he is boastful and violent. Between the lines, Steinbeck is portraying a sad, isolated character who is doomed to be unsuccessful when she reaches out to other human beings because of her position on the ranch. In this scene, we also see what might be described as an extremely nasty side to Curlers wife. When the conversation does not go her way – Candy openly insults her she turns on Crooks, using her one element of power as a white woman over a black man: Well, you keep your place then, Nigger. I could get you strung up on a tree so easy it ain’t even funny. Although this threat is abhorrent, perhaps it indicates the level of her frustration with her own position. She is at the bottom of the hierarchy of white people, and her only form of control could be to accuse Crooks of some sort of inappropriate behaviour that would lead to his being put to death. The final time we see Curleys wife is the only time she seems to open up and reveal her vulnerability nd her disappointment with the way her life has turned out. Ironically, even as she is confessing all, ‘l ain’t told this to nobody before. Maybe I oughtn’t to’, her audience, Lennie, is not listening because he is caught up in his own fantasy world. Therefore, although this scene serves to show the poignancy of Curlers wife’s character, it also underlines that at no time in the novel does she succeed in making any human contact. When we learn that ‘her words tumbled out in a passion of communication, as though sne hurried betore ner listener could be taken away, it is as though sne as had her story, her identity, bottled up inside her and she is desperate to share her hopes, dreams and disappointments with anyone who might listen. Her background reveals a sad and lonely childhood full of mistrust. We learn that she has a poor relationship with her mother and that she has enjoyed male attention which has probably been superficial and has led to her believing that she could have had a career in the movies’. Curleys wife’s naivety is emphasised by the way that she behaves around Lennie. She flits between thinking he is ‘nuts’ and encouraging physical contact. She believes that e is ‘Jus’ like a big baby, and although she is aware that he had crushed Curlers hand, shows no caution around him when she offers for him to stroke her hair. This may be because she is so over-excited by the fact that she believes that she has somebodys attention – possibly for the first time since arriving on the ranch – that she does not think beyond the moment. The reader knows that Curlers wife is doomed the minute she says that she likes to stroke her hair because it is soft. There is a poignant irony that it is her offer to Lennie that leads to her death. She is enjoying the attention and perhaps is also lightly motivated by a moment of kindness to let Lennie enjoy the feel of her hair. Ultimately, though, it is her concern with her appearance: You’ll muss it up†¦. You stop it now, you’ll mess it up’ that makes Lennie inadvertently break her neck in a panicked effort to keep her quiet. The image Steinbeck uses to describe the moment of her death dehumanises Curlers wife: ‘her body flopped like a fish’. It is in the final description of her that it seems that we are offered a true account of Curleys wife’s true essence: ‘And the meanness and the plannings and the discontent and the ache or attention were all gone from her face. She was very pretty and simple and her face was sweet and young. ‘ This short passage shows that underneath her hardened exterior she was in essence a decent person, which is what Steinbeck refers to in his letter to the actress. The ‘ache for attention’ had had the opposite of its desired effect, in fact pushing people away rather than attracting them to her. Furthermore, her dream to be a movie star or iconic figure is echoed in the almost Sleeping Beauty-like description of her: ‘Now her rouged cheeks and reddened lips made her seem alive nd sleeping very lightly. The only time Curleys wife is described in a positive manner is in her death, and even this is quickly negated by Candy placing blame on her for ruining their dream: You God damn tramp†¦. Ever’body knowed you’d mess things up†¦ You lousy tart’. In conclusion, Steinbeck uses a number of techniques to create Curlers wife. Some readers may feel sympathy for her, others may share the ranch workers’ view of her. For my part, I see her as the epitome of loneliness; her only defence against a sexist environment ironically leads to her further alienation. How to cite Curley’s Wife, Papers

Lab Report Operational Amplifier Application Essay Example

Lab Report Operational Amplifier Application Paper In this report, we Will go through two experiments, Which are the fundamental circuits of operational amplifiers: non-inverting and inverting amplifier circuits, to analyze the difference between ideal and real pop-amps. For the following section, the relevant theory will be introduced, and then the detail and results of the experiments Will be discussed before proceeding to conclusion. Theory Figure 1 The pop amp and its ideal attributes As the Figurer shown, operational amplifier has two inputs labeled (+) and (-) with positive and negative power supply, and a single output. It is primarily a sigh gain differential amplifier which amplifies the difference tot voltages been two inputs. The output voltage of the amplifier Bout is given by the following formula: Bout = A (VT V-) Where A is the open loop voltages gain of the amplifier, which typically is very large about ISO at low frequency. And V- are the non-inverting and inverting input voltage respectively. From the equation, output voltage is entirely governed by the difference between the two input voltages. However for real pop-amps inputs do draw a small amount of current and the output voltage is affected by the output current drawn. Poor the analysis, both inverting and non-inverting amplifiers are applying negative feedback. It cause the V- to increase, hence voltages Of the two input terminals Will be much closed together. And the input draw current is assumed to be zero. Therefore Kerchiefs first (current) Law and Kerchiefs second (voltage) Law could be applied.

Inverting amplifier: Bout=-RFC Vein Inverting amplifier: Figure 2 Inverting Amplifier Constructing the circuit of an inverting amplifier as shown in figure 2 on the test board. In order to make an amplifier with a gain of . 10, setting RI 2. 7 k and RFC = 27 aquaplaning a Homage signal generator, a KHz sine wave was supply into the amplifier input, the amplitude should be adjusted to low values to prevent waveform distortion occur. Moreover, connecting the input and output of amplifier to X-Y channels of the Oscilloscope, to check the waveform and verity the amplification, If both inputs are held at a common zero, the offset voltage will not be zero as deadly owing to a small amount of bias currents and internal imbalances of a real amplifier. Setting the oscilloscope to X-Y mode, a graph like Figure 3 will be display in the screen. The output offset voltage which is the sum of two independent variables, one is Input offset voltage (Vein offal the other one is input bias current (In bias ). The equation of the Bout off is given below: Bout off=Vein offal+RFC+line bias RFC For the experimental purpose, the values of RI and RFC should be varied to form simultaneous equations, as a result, Vein Off and In bias could be derived separately. When applying RI = 2. Non and RFC = kick , the value of offset voltages Obtained was urn: furthermore, the value Of Bout Off increased to I Iron While RI = 0. Aka and RFC = Aka. Hence the simultaneous equation could be solved: offshoot 2. K*line bias ask Vein off= 0. 916 NV offal bias ask In bias 06. 92 an Figure 3 WY mode trace of Bout against Vein With the respect to Figure 3, the values foeman and Vein acquired from experiment are and -1 IV, therefore the real output voltage range is from -IV to +13. IV when  ±IV supply rails are being used. Additionally, two horizontal nines reveal that maximum and minimum output voltages will less than the supply rail voltages due to the energy losses in the internal resistors. Figure 4 Measurement of the output impedance Measure the output impedance of the inverting amplifier by setting input voltage to ground, and injecting a load current to output side by adding a signal generator which drives a 10 kHz sine wave via a 2200 resistor. Compare the difference between V out and V load shown in figure 4 by applying the oscilloscope, so that the output impedance could be derived by following equation Output impedance: V outlet here lout=(V load- V out)220 As the result, the value Of output impedance obtained from experiment is I . Q, which is quite small but still not equal to zero as ideal situation. In addition to this, V out Will rise when the frequency Of the signal is increasing; Meanwhile, the closed loop output impedance Will tend to zero. Because the deviation between the V out and V load is getting smaller. Inverting amplifier: Bout=1+Riving Non-inverting amplifier: Bout= 1 Vein Figure S: Nan-inverting amplifier Converting the circuit in to non-inverti ng amplifier and using the same values of RFC and RI ,Moreover, applying the signal to the positive input of pop-amps, thus a positive gain can be acquired Much more interesting, the output offset voltage and output impedance will stay the same as values obtained from inverting amplifier. The reason is the resistors for both circuits are consistent. Discussion Prom the investigation Of the experiments, the gain Of non-ideal amplifiers is finite and it could be affected by the changing in frequency and existence of input Offset voltages. Experiments have shown that there is error input voltage due to the non-zero bias currents flowing in the input terminals. Also they have proved that the maximum gain Of real pop-amps is finite and limited by maximum and minimum supply voltages. During the experiment, it is vital to be aware of the error that may occur. Generally, errors can be divided into tuft categories which are the systematic errors and random errors. Unfortunately, systematic errors are unavoidable because of the existing error in the equipment used in the experiments. For instance, homage DVDs can accurate about 0. 1% for DC voltages and 0. 2% for resistance; the accuracy of AC signals is around 1% while the frequency is within angel from GHz to kHz. However,the random error could be minimized to the best extent by taking several measurements and using the average values. Conclusion The results acquired from the experiments reveal the properties of both inverting and non-inverting amplifiers, and describe the differences between real and ideal pop-amp Further, the phase relationships of input and output voltage for the inverting amplifier are 180 degrees out of phase; as opposed to this, they are in phase with each other for Nan-inverting amplifier.
