Wind Technology essays

Wind Technology essays Since early history, people have been harnessing the energy of the wind. Wind energy propels boats along rivers, simple windmills, and pumping water as early as 5000 B.C. New ways of using the energy of the wind eventually spread around the world. By the 11th century, people in the Middle East were using windmills extensively. Settlers took this new technology to the New World in the 19th century. They began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and industries. In the 1940s large wind turbines began to operate small industries. Wind turbines fall into two basic categories, the horizontal-axis variety, and the vertical-axis design. Modern wind turbines take advantage of many of today's high-tech technology uses such as aerodynamics, engineering, and electronics. Wind turbines that are grouped together are called "wind farms", and generate a lot of bulk electrical power. Wind farms are in a variety of sizes and power ratings, depending on the location of where the farm is located. Some of the wind turbine propellers can span more than the length of a football field, and can stand up to twenty stories high, which creates enough electricity to power 1,400 homes. Some of the smaller turbines are 8-25 feet in diameter, and stand up to approximately thirty feet tall, which supplies the electrical needs of a small business or an all electric home. Constructing electric-generating wind turbines, regardless of the shape or size, consists of the rotor, the electrical generator, a speed control system, and a tower. Some wind turbines have the options of fail-safe shutdown systems. Fail-safe shutdown systems are designed to turn the blades out of the wind, or simply "put on the brakes" in the event of a mechanical failure. Wind energy is abundant throughout the United States. Characterized by wind-power density classes, ranging from the lowest c ...

Neoclassicism in Music Essay Example | Topics and Well Written Essays - 750 words

Neoclassicism in Music - Essay Example Neoclassicism as a musical term was not coined until sometime after its supposed development began. Rather than a style of composition, the term initially referred to a conception or reaction to a musical historical event. That is, Neoclassicism represents a way of viewing music history as a reaction to the contemporary trends in fin-de-sicle France that regarded the current musical trajectory as one that was defined for the most part by German musical historical conceptions and aesthetic trends. Namely, the music of Wagner was perceived by a growing number in France as, decadent and unduly romantic. However, the original use of the word "neoclassicism" did not refer to originally to a reaction to the German Romantics, but a somewhat derisive term to refer to writers and other artists, who parroted Greek and Roman themes as a kind of sterile, lifeless, pastiche-rather than a reinvigoration of the classical spirit that perhaps one might envision such a term connoting. Thus, the neocla ssical style in music was more correctly labeled at the time Nouveau Classicisme. Messing then explicates the role that composers such as Saint-Saens, Debussy and Ravel whose interests in composers before Beethoven such as Mozart, Bach, Handel and even earlier such as the work of the Couperin family played out in some of their compositions. Messing technical analysis of the musicological comparisons between the work of these new classical French composers and their classical counterparts reveals a rhythmic and structural similarity. Yet that similarity did not extend across the new classical scene, rather the particular inspiration that the above composers chose was modified and developed so as to make any comparison between say Saint-Saens and Debussy much more tendentious. Therefore, Messing notes to place this musical aesthetic ideal under some uniform stylistic rubric called "neoclassicism" was invalid. In another chapter, Messing deals with post-war neoclassical analysis through the work of Igor Stravinsky and the eventually polemic that developed between his followers and the Arthur Schoenberg and his revolutionary serialist style. Moreover, as Messing suggests neoclassicism as a distinct music style with specific gestures did not congeal until after the war and its juxtaposition with the work of Schoenberg. It seems according to Messing that the intervening war caused a radical shift in understanding of the term and its followers from one which represent a musico-historical reaction to Wagner in France, to a theoretical shift in composition. The disparate influences of the earlier neo-classicists seemed to have been conflated together in the comparison to the work of Schoenberg and his prodigious number of students. Moreover, it can be seen that Stravinsky's music, which was supposedly indicative of this specific style was no so radically different from the work of Schoenberg, a nd thus suggesting that only are the differences between neoclassicism and serialism overwrought and artificial. It also reveals that to conceive of neoclassicism in

Upward mobility Essay Example | Topics and Well Written Essays - 2000 words

Upward mobility - Essay Example This third time-level represents one facet of several possible comparisons between the narrator and Sa'eed, all urged by the construction of the novel around this pair of characters.At the very beginning of the novel, the narrator refers to his time in England as seven years of longing and describes the place as "a land 'whose fishes die of the cold'". The narrator's characterizations of his studies abroad are typically vague and completely lacking in detail (as in the preceding example) or dismissive. The narrative of Mustafa Sa'eed's experiences as a student, intellectual and Sudanese expatriate in England. This time-level first appears relatively late in comparison with the other time-levels, (Tayeb , 183) After offering this optimistic cross-cultural comparison, the narrator notes the ominously silent Mustafa Sa'eed, who "said nothing". Sa'eed's silence parallels the narrator's own reticence to share all his thoughts with the villagers, a reticence which possibly reflects deeper misgivings about the truth of his upbeat observation. The narrator thinks to himself that in England, just as in the Sudan. Some are strong and some arc weak; that some have been given more than they deserve by life, while others have been deprived by it, but that the differences are narrowing and most of the weak are no longer weak. This comparison begs the question, however, of whether the same can be said of the relationship between England and the Sudan, rather than within both England and the Sudan.30 For Sa'eed, as both we and the narrator learn in subsequent chapters, a chasm separates East/South from North/West, a gulf reflecting powerlessness and power, respectively, in response to which he embarks on his personal program of violent revenge. Even before Sa'eed's story is begun, however, Sa'eed questions the relevance of the narrator's experiences abroad. Sa'eed introduces himself to the narrator and remarks, in a vaguely dismissive manner, on the latter's achievements. (Tayeb , 183) Solid and unproblematic values, the humanistic act of studying another culture's literature, and the virtue of humility, all appear in conjunction with the narrator's experiences in Europe. Yet the dissimulation calls into question the values implicit in the narrator's very general description of his experiences abroad. Sa'eed responds by attacking the narrator's choice of subject: "We have no need of poetry here". Sa'eed's blunt criticism reflects the unviability of the naive model offered by the narrator for a possible relationship between England and the Sudan. The eager Sudanese student assiduously applying himself to the acquisition of the higher (in both senses) European literary culture offers, for Sa'eed, a pathetic reflex of the rapa ciousness of European Orientalism (including philology): "a Western style for dominating, restructuring, and having authority over the Orient. Even though it is Mustafa Sa'eed who is speaking, the narrator's own experiences in an idealized England populated by poets, humanists, and doctoral candidates render English poetry intelligible to him. Ironically, precisely those idealized experiences allow him to perceive Mustafa Sa'eed as an interloper in the otherwise (also highly idealized) cultural homogeneity and simplicity of the village. The narrator's

Factors affecting intellectual development Essay Example for Free

Factors affecting intellectual development Essay -Whichever has a bigger influence remains a debate until now because some studies proved that heredity has a bigger influence on intelligence while some studies showed the opposite. The important point is that the interplay of both heredity and environment is essential for maximum development of the intellectual abilities of the individual. Other factors affecting Intelligence: 1. Culture Different cultures foster different patterns of ability. For instance, students from Sri Lanka showed higher score in verbal ability than the Americans. -This can be explained by the fact that in Sri Lanka, the philosophers and the poets were admired rather than the scientists or engineers. 2. Sex It is not true that males are more intelligent than females. However, studies show that boys excel girls in spatial ability, in problem solving, and numerical ability whereas girls excel boys in memory, reasoning, and fluency. -The difference is not due to solve problems since they will be the heads of the families. Girls have been trained to do light work since they will be the homemakers, anyway. 3. Health Studies have shown that high IQ goes with healthy condition of the body. -In school; healthy children have better chances of learning, they can concentrate better in their studies and they are often active and enthusiastic about classroom activities. 4. Race No one race is endowed with better intelligence than others. -Differences in achievement of races are due to better opportunities and facilities found in developed countries. 5. Socio-economic status Studies have shown that children from higher socio-economic scored higher in  intelligence tests. -Again, greater opportunities and money account for this. The rich can send their children to better schools and can provide stimulating environment to their children. However, there are geniuses and idiots among them as there are among the poor.

Macbeth-Tragic Hero :: essays research papers

Macbeth-Tragic Hero   Ã‚  Ã‚  Ã‚  Ã‚  As I finished reading Macbeth by William Shakespeare I realized the true reason that Macbeth is considered a tragic hero. Like all other tragic hero’s he had many good things going for him in his life before he messes with self- destructing things and threw it all away.   Ã‚  Ã‚  Ã‚  Ã‚  Macbeth had a great marriage, he was Thane of Glamis, the people and the king respected him and he was well liked. He was a generally happy person without much greed or jealousy in his life. This was until evil and the devil overcame him. He started getting greedy and wanted more. Once the thought of being king entered his head and once he shared that with his wife, there was no turning back. He was bound to destruction.   Ã‚  Ã‚  Ã‚  Ã‚  Macbeth was weak because he allowed his wife saying that he was not a true man get to him. He had to prove to his wife that he was a man and his only way of doing that was through murder. Even though he had hesitations and second thoughts about it, he did it out of love for his wife and the possibility of his triumph; he may actually become king. He allowed this to become an obsession and he did end up killing Duncan, his king. This started him down the road of doom. He suddenly had a very evil streak that was never there before and this was revealed more often than ever. He began letting the evil take over and murdering more and more people thinking that he was only saving himself. What he did not realize was that he was only harming himself in the long run. He was driving himself mad and he was no longer himself.   Ã‚  Ã‚  Ã‚  Ã‚  Macbeth was just like other tragic hero’s such as Elvis Presley. Elvis had much going for him and he thought that the drugs and alcohol were helping him deal with his stress and fame but in the long run it killed him.

A Victims Deliberate Use of Deadly Force

Domestic violence causes far more pain than the visible marks of bruises and scars. It is devastating to be abused by someone that you love and think loves you in return. My resolution that I will be debating is â€Å"A Victims Deliberate Use of Deadly Force is a Just Response to Repeated Domestic Violence†. Domestic Violence is a pattern of behavior which involves the abuse by one partner against another in an intimate relationship such as marriage, cohabitation, dating or within the family.I value the life of both parties including the person who is committing the act of domestic violence. The victim of domestic violence isn’t justified in using deadly force unless the person is committing an act of domestic violence on the victim right that moment. That statement brings me to my first contention, the life of each person involved in a domestic violence dispute are both important. If you are the victim of repeated domestic violence you shouldn’t use deadly force unless it’s in self defense. Read this â€Å"The Secrets of Haiti’s Living Dead†Murder in the first degree is any murder that is willful and premeditated and by killing the man or woman that committed the act of domestic violence you are indeed going to prison to be put on death row.

The Heroic Stand Of Crossing Into Womanhood - 1898 Words

Jasmine Ware July 26, 2016 Research Essay A Bold Act of Love: The Heroic Stand of Crossing into Womanhood In Henrik Ibsen’s play A Doll House he uses an individual female, Nora Helmer, as being the most predominant character who has been controlled most of her life by her father and husband. Nora’s husband, Torvald Helmer, is seen to be an overprotected husband that leads Nora to believe she is a precious little doll in obeying his commands. During the play Ibsen uses another character, Nils Krogstad, who soon begins to become a part of Nora and Torvald’s marriage. Mr. Krogstad is a bank clerk that was under the management of Torvald, but later in the story he is threatened to lose his job. In the play, Nora and Krogstad become partners†¦show more content†¦Clearly Nora does not have the proper means financially, physically, or educationally to maintain a stable household for her kids and husband. Nora’s relationship with her father and Torvald has shaped her into the woman she is posing to be. She is under a mutual control being a shadow of what they want her to be. Many people see Nora as being the weakest link in this poem, considering her lack of ability to voice her opinion. Throughout the play, Torvald constantly uses little childish names when addressing Nora perhaps when he says â€Å"Is that my little lark twittering out there?† (Ibsen 1190). Nora’s mindset clearly begins to overlook the fact that Torvald may be picking at her in a way. Torvald is also seen to be picking at Nora for eating macaroons when he makes the statement â€Å"Surely my sweet tooth hasn’t been running riot in town today, has she?† (Ibsen 1192). This clearly states that Torvald’s opinion of macaroons is invalid for Nora, because he would not want her to become fat in possibly ruining his image. Nora’s childhood is the birth of all future relationships that grants control, which makes Nora feel as if she has no power in being an independent woma n. Nora is seen as a little precious doll who is a valuable possession of her father and husband. She never feels like she has the courage to stand on her own and be a woman because all she knows is being under the control of someone else. The first aspect of Nora crossing into womanhood was symbolized by the
