How to Use Gold in Wind Turbine - Case Study Example This explains the re-emergence of wind power as a green and sustainable source of energy. The argument behind the re-emergence of wind powers source of energy cannot only be looked at in the context of milling rain or pumping of water as was the case in the past, but is all about the energy needs that have grown due to globalization and industrialization (Schmid and Klein 1990, p.17). Wind power is generally harnessed from wind in motion, which is transformed into energy with the help of a wind turbine. Blaabjerg and Chen (2006 p.1) note that wind turbine has been one of the fastest growing renewable energy technologies. Its development began in the 1980s with just some tens of kilowatts in terms of power rating to the current megawatts. Blaabjerg and Chen argue that in the past, production of wind power did not have a lot of impact in the system of power operation and control, but today it contributes a lot in energy supply since the level of power penetration is on the rapid increa se (Paraschivoiu 2002 p.45). In the beginning, the technology used in wind turbine was generally the squirrel-cage induction generators, which were directly being connected to the grid. During this time, there were no active controls of active power reactors. The parameters used for control has become necessary due to the increase in the power range for the wind turbines. Blaabjerg and Chen note that the introduction of power electronics has led to a change in the basic characteristics of the wind turbine from a source of energy to an active source of power. In recent times, many nations are making a rash toward the use of gold in the manufacture of the wind turbines. This paper will discuss the main parts that make up a wind turbine and their functions. The paper will also discuss the choice of materials that are used in the manufacture of the major parts and where gold as a raw material is used under the current design and where it can be used. Main Parts Of A Wind Turbine And The ir Functions Ancona and Mc Veigh (2001 p.1) note that wind turbines usually come in a varying sizes and configurations, built from different materials. The wind turbine consists of four main parts; the rotor which has wing-shaped blades connected to a hub; a nacelle which holds a drivetrain consisting of a gearbox, support bearing, connecting shaft, the generator and the machinery; a tower; and the electrical equipment mounted on the ground Ancona and Mc Veigh (2001 p.3). Turbine Rotor Blade The turbine rotor is the part that coverts the alternating wind energy into a mechanical energy, which is then converted into electrical energy via a generator, which is then moved to the grid with the help of a transformer and lines of transmission. Within the wind turbine there exists a blade aerodynamically designed that captures the wind power and converts it to rotating mechanical energy. Blaabjerg and Chen (2006 p.3) note that the number of blades that make the rotor may vary. The speed of rotation usually decreases with an increase in the radius of the blades. For instance, for a wind turbine of megawatt range, the speed of rotation ranges between 10-15 rpm. The blades exist in different sizes from about 34 to 55 meters. The rotor blades are made of materials such as carbon fiber, balsa wood, and fiberglass with high tensile ratio. The materials are usually modeled to form airfoils that

Additionally, the model can be used to check the viability of the firm before seeking employment and also to predict business failure of the company Debt rating refers to the continued monitoring of the firm’s financial status after they have been issued with a debt (Javier, 2014). The ratings are expressed as letters ranging from ‘AAA’ which represents the highest investment grade to ‘C’ which represents the lowest investment grade. This rating has an impact on the returns that must be offered in order to sell the debt instrument. For a firm to be considered suitable for investment, it must achieve a greater credit rating which is a crucial threshold because many funds are prevented by their ratings from any investments in bonds. Using the Standard and Poor’s debt rating agency, the above ratios indicate that the firm has a credit rating grade of B and below which is the low credit rating also referred to as the non-investment grade and is an indicator that the company is facing significant financial risks. Therefore, the power corporation should take necessary steps to prevent the company from being declared

Spiritual Journeys: Dante And St Augustine

Spiritual Journeys: Dante And St Augustine The individual spiritual journeys of Dante in the Divine Comedy and St. Augustine in the Confessions are quite similar, as each man searches for divine love and grace, and true eternal closeness to God. Both Dante and St. Augustine admired and were heavily influenced by Virgil, the classical Roman poet of the Aeneid, in their writing and works; however, because of their strong Christian faith, Dante and Augustine also make it clear in their autobiographical accounts that Virgils pagan beliefs cannot receive salvation, or allow the soul to enter heaven after death. Dantes journey begins with the poet being portrayed as spiritually lost in sin, in the darkness of woods, when a guide is sent to him in the form of the ancient Roman poet Virgil, who represents human reason and wisdom. Virgil tells Dante that the only way out of the darkness is for Virgil to lead him through Hell and Purgatory, in order for Dante to recognize the nature of sin and the consequences of his actions. Once Virgil has guided Dante to the top of Mount Purgatory, where the renunciation and rejection of sin occurs, Virgil tells the Pilgrim that he can no longer accompany him on his final journey to Heaven, because human reason cannot reach the ultimate height of Paradise. Dante is lead instead to Heaven by his beloved Beatrice, who is now living as one of the blessed in the afterlife, and who also symbolizes divine love. Much like Dante, St. Augustines journey also begins with his confessions as being spiritually lost, especially in his earlier years as a sinful youth, turning away from God, and preoccupied with only worldly desires and needs of the flesh. St. Augustine implores in Book VI of his Confessions, Thou hadst made me wiser, yet did I walk in darkness, and in slippery places, and sought Thee abroad out of myself, found not the God of my heart; and had come into the depths of the sea, and distrusted and despaired of ever finding truth (Augustine 94). Here St. Augustine talks about the darkness he walked in during his early life, very similar to Dantes struggle and despair in his own dark woods of sin, where Virgil finds him in the beginning of the Inferno. St. Augustine describes his spiritual void and emptiness further, stating, And I perceived myself to be far off from Thee [God], in the region of unlikeness (134). In this declaration, St. Augustine is associating his many sins with a regi on of unlikeness, which causes him to wander aimlessly without direction or purpose, becoming hopelessly lost. Whereas Dantes descent into Hell in the Inferno is both dramatically real and an allegorical representation of his souls journey towards God, St. Augustines Confessions represents a metaphorical rather than physical journey of the soul, as Augustine searches for divine truth and grace. However, both men view this spiritual descent as necessary in order for the human soul to attain ultimate closeness to God. An example of this is expressed by St. Augustine in Book IV of his Confessions, when he states, Even now, after the descent of Life to you, will ye not ascend and live? But whither ascend ye, when ye are on high, and set your mouth against the heavens? Descend, that ye may ascend, and ascend to God. For ye have fallen, by ascending against Him (64). Furthermore, according to John Freccero, author of Dante: The Poetics of Conversion, In the spiritual life, one must descend in humility before one can begin the ascent to truth, and in the physical world, according to both Dante and A ristotle, one must travel downward with respect to our hemisphere in order to rise (74). This spiritual belief of descending in humility before one can rise again is clearly echoed by both Dante and St. Augustine in their poetic works regarding Christian faith. Virgil, the pagan Roman poet of the Aeneid, also plays an important role in the autobiographical accounts of Dante and St. Augustine as well. Dante uses Virgil as his guide to illustrate Virgils supreme human reason and intellect during his journey, as well as emphasizing Dantes heartfelt admiration for the classical Roman poet. However, to demonstrate and make clear his devout and strict Christian beliefs, Dante places Virgil in Limbo, the first circle of Hell, along with other virtuous pagan Roman poets of the past. Dantes placement of Virgil and the other non-Christians is essential, since they can never be allowed to enter Paradise because of their pagan beliefs. Virgil himself understands this divine judgment delivered by God, when he states to the poet Sordello in Canto VII, I am deprived of Heaven for no fault other than my lack of faith (Alighieri et al. 56). Dante shows that despite Virgils moral perfection, he was without faith, and human reason alone can never reach Heaven . St. Augustine also admired the Roman poet Virgil during his early life, and being a successful teacher of rhetoric, Augustine understood very well a life led by reason. However, he, like Dante, discovers that reason alone is not enough to gain salvation from God, and as a result, was spiritually lost, tormented by temptation and sin. Thus, St. Augustine too realizes it is only when one has true faith in God that eternal salvation can be achieved. As Olson reminds us, Augustine testifies to how reason puts man on the road toward God, and how it is [only] faith that informs and elevates reason, taking it beyond its natural limitations while never being tyrannical or confining in any way. [St. Augustine] summarized this seemingly paradoxical fact in the famous dictum, I believe, in order to understand; and I understand, the better to believe (Augustines Confessions). History of Portraiture: Changes in Styles and Techniques History of Portraiture: Changes in Styles and Techniques The immemorial fascination of mans own image and of those of his fellow human beings arose a desire in men to attempt and embellish his likeliness into a physical medium. However at the time portrait was exclusive to those who wished to celebrate mans relationship with God and the divine rulers of the times, which makes the Renaissance a revolutionary era for portraiture and the development or artist techniques. The common subjects of royalty and wealth were joined together with the trivial and oppressed, giving artists around the world more latitude to delve into painting intricate and thought-provoking portraits to be cherished for centuries. Deciding to undertake the task of compiling the substantial triumphs for portraiture styles and methods over time, I plan to introduce it in the span of six notable art movements and cover the most significant artist of the time. The theme portraiture hold a special place in my heart, its enigmatic and flexible principles give the artist the u pmost freedom to depict people in a way that suits them. Its a theme that lasted through the test of time, becoming more and more popular as the centuries turn. Jan Van Eyck was a powerful visionary in 15th century with his command of linear perspective and capticating interiors that bathed in golden lights, his art sank into oblivion until the 1930s. Expressing a new awareness of reality through the use of oil paint, he crafted remarkable paintings and portraits that had remarkable attention to detail, observation of nature and light, and constructing spaces steeped in elegant interior which inhabited realistic characters. His careful positioning, golden lights and expert command of the technique of oil painting made him one of the most significant representative of the Renaissance art movement. His style and technique was a step up from the less realistic depiction of human forms by the then pre-Renaissance artists Giotto di Bondone and Cimabue. As the 17th century approached, the subject for painters was changing as the patrons no longer served an essential role in the choice of subjects and composition. Michelangelo Merisi da Caravaggio painted people who were then counted as trivial: peasants appeared alongside sovereigns and saints, crafting a new approach to portraiture for his time. At the beginning of his artistic career he broke through with his loose interpretations of traditional subjects, painting the first still life in the history of art as a subject in itself and knowingly portrayed saints as everyday people. The conventions of his time didnt worry him, nor did the already established art guidelines. He did not make primary sketches but place the paint straight to the canvas, using the foundation coats as an artistic element.   The early works of the artist revealed his love of poetic naturalism that was inspired by his everyday life. Caravaggios approach to chiaroscuro (the artistic play of light and shadow) was a clear departure from the art conventions of Mannerism. These conventions found their way into the most significant Baroque and Rococo artists. In the 18th century, a new freedom became apparent with the French painters as they began portraying a carefree and libertine behavior of society consistently in their artwork. The most noteworthy artist of the time was the Rococo painter Franà §ois Boucher. He was highly adept in many forms of media as he switched traditional bright oil paints to forms of decorative art. Adopting a high tone palette that favoured blues and pinks, he set a definite foundation for most paintings of dream-like quality. His paintings of beautiful women in rich silk clothing endorsed scenes of erotic and passionate love. Oil and gouache sketches were common in preparation for his bigger commissions as his careful attention to finer background detail made the scene more poignant and alive, filling it with character and passion. The dream like qualities of his prominent artwork carried on into the triumph or Romanticism. The spirituality and the influences from the previous eras stimulated the imagination of artists around the world. The art historian and theoretician of colour, Eugà ¨ne Delacroix was and still is the acknowledged master of Romanticism and one of the last great decorative painters. His passion for colours and the depiction of lively composition is reflected in his canvas won the admiration of the public. Everything is the subject; the subject is yourself: our impressions, your emotions when faced with nature. he professed. His skill in the thick impasto unified well with his choice of colours, giving his paintings the form of a sketch. The innovative take on colour, the earthy shades and the use of rich varnishes changed the way most artists composed their portraits and subject matters, crafting their styles to match Delacroixs. The analytical approach to colour is recognised in almost all realism, impressionism and art nouveu paintings that dominated the early 20th century. The creations of Vincent Van Gogh, albeit spanning over a short period of ten years, contained distinguishing marks of his life and the tourment he endoured as well as the places he lived in. The canvases beared his trademark frantic colours and figures in the form of various self-portraits, landscapes and scenes from ordinary day to day life. His impact on art gave colour a new meaning in the works of artists and put forth a new style in which the painter can place his brush on the canvas. A new approach to light and colour enabled him to go beyond both Impressionism and Neo-Impressionism, enabling his style in his self-portraits to experience a change that brough critisim upon him at the time. The intense expressiveness, accompanied by a turmoil of brush strokes produced a new wave of artists stimulated to create more illusive and stylised paintings to continue the tradition of expressive portraiture.

court system Essay -- essays research papers fc

The basic role of the Canadian court system is to deliver justice between two individuals or two individuals and the state. There are four levels of court in Canada. Provincial courts are the lowest in terms of power. They handle most of the day to day cases. The next court in terms of power is the provincial and territorial superior courts. These courts take care of the more serious crimes that are admitted into the system, and can also take appeals from provincial court judgments. Another that has the same amount of power as the provincial and territorial superior courts is the Federal Court. Next are the provincial courts of appeal and the Federal Court of Appeal. The court with the most power in Canada is the Supreme Court. All members of the judiciary in Canada, regardless of the court, are taken from the legal profession. Each province and territory has a provincial court. All cases involving either federal or provincial laws take place here. These courts don’t particularly have similar names, but they follow the same rules. Provincial courts deal with the most cases, most of which include: provincial regulatory offences most criminal offences, traffic violations, family law, young offenders. Private disputes involving money can also be dealt with at this level in Small Claims courts. As well, all preliminary inquiries take place before the provincial courts. Some provinces and territories have domestic violence court programs. These programs provide services to victims. There are specific courts set up for certain offences. The object is to address the needs of non-violent offenders who are charged with criminal offences. Youth courts handle cases that have someone with the age of 12-17 is charged with an offence. Depending on the age of the youth, different precautions are taken, for example privacy protection. Courts at either the provincial or superior court level can be designated youth courts. These courts are often referred to as inferior, but are only called that to show the difference in power between the other courts, and it’s ranking with them. The superior courts of each province and territory both have a court of general trial jurisdiction and a provincial court of appeal. Something different about these courts is that they have more power than just their own province. They have power over areas where the federal government is granted l... ...the lower courts, it can be 75 as well, or 70.

The first main concern for the construction of the project is the funds. So as the mayor of Calcutta my first step is to get the funds required to start up this project. These funds would be acquired from various sources like donations, taxes, and loans. Once the funds are acquired, the next step would be to look into the plan of the project. I would take the opinion of a few well-known engineers before an actual plan is taken up. I would make it a point to see to it that the various pros and cons of different plans are taken into consideration before starting the project. Then I would select that project which would give us the maximum benefits within the obtainable budget and least disturbances to the normal life in the city. I would consider the efficient labor to carry on the work of this project. I would play close attention and make sure that all the basic facilities that are required by the citizens would not be disturbed due to the commencement of this project. Every possible option would be exhausted to make sure that the project would not cause any kind of inconvenience to the normal life of the citizens. In my opinion there is no such thing as bad luck and nothing happens by chance. Everything is planned and has a definite purpose. It is only our hard work that will make us or break us. Therefore, it is important to take into consideration a 360 degree view of any problem before we solve it. If the situation is looked upon from only one angle, then all the disadvantages of the remaining angles will occur. Although it may be a little time consuming and painful in the beginning, it is important to know that the hard work pays it all. Had the mayor seen the consequences of starting this project from various points of view. I believe this situation would not have been escal ated at all.

Key characters in this book are Jesus, John the Baptist, Lazarus, and Mary Magdalene. The first part of John tells of Jesus’ ministry and teachings. John tells of how Jesus performed miracles such as healing the lame and blind and bringing Lazarus back from death.The story of the feeding of the five thousand is also mentioned in John. In chapters 13-17 John tells of Jesus’ time just before his death and resurrection. Here, Jesus prays for His disciples and for Himself. The last part of the book tells of the death, burial, and resurrection of Jesus Christ. Here, He is crucified on the cross after being trialed and convicted illegally. Jesus appears to Mary Magdalene after arising from His tomb. He also appears to His disciples.ActsThe genre of this book is narrative. The key theme of Acts is showing the reader how believers in Jesus were empowered by the Holy Ghost to spread His Word throughout the world. Key characters are Paul, Peter, John, Stephen, Timothy, and James. The author of Acts is Luke. The beginning chapters tell of the Church starting from infancy. Peter delivers a wonderful sermon to the Jews. As a result, three thousand people accepted Christ as their Savior.The apostles start spreading the Word to different areas. Luke tells of how Stephen is falsely accused and stoned to death. The Apostle Paul (originally named Saul) has a life altering experience while traveling to Damascus. Before being convicted by the Holy Spirit, Paul oppressed early Christians. The last parts of Acts tell of the gospel being spread to the Gentiles. Paul travels to Macedonia with Silas to spread the gospel. Paul then travels to Jerusalem and gets arrested and is imprisoned.HebrewsThe genre of this book is epistle. The purpose of Hebrews was to show Christians that Jesus Christ was perfect and greater than anything Judai sm had to offer. The author wrote Hebrews to a group of Christians that were debating returning back to Judaism and reverting back to their old ways. Unlike other books in the New Testament, Hebrews brings focus on the Old Testament. In early chapters of Hebrews, the author presents to the reader the power of the Word. He also tells that,† faith is the assurance of things hoped for, the conviction of things not seen†(11:1) The author gives us great examples of the faithful people from the Old Testament and tells of having faith in Jesus is the basis of our salvation. The author conveys to the recipients of Hebrews that straying away from faith will have consequences and that they not turn away from the Truth.JamesThe genre of this book is epistle. The purpose of James was to encourage Jewish believers to live great Christian lives and to continue growing in faith. The key characters in James are himself and Jewish Christians. James teaches the relationship between faith and works and how faith should be put into action. He states that we should not only listen to the Word but be doers of the Word and that good works are not the cause of salvation. Good works are the result of salvation. He tells the believers that everyone is a sinner and if even one of the Ten Commandments is broken, then all are broken. James then instructs that we should submit to God and serve Him and to turn away from evil. He ends the letter telling us to be patient in suffering and to pray for one another. He also expresses to us the importance of living in faith.RevelationThe genre of this book is apocalyptic. The purpose of Revelation is to give hope to all of us and to continue to watch for the return of the King. It also gives of warning of the Final Judgment and what nonbelievers will have to endure. The author of Revelation is John. He explains how an angel comes to him in a vision instructing him to send letters to seven churches about his revelation. The book tells o f how the final days will be on earth and how there will be an Anti-Christ that will rule until God throws him into the Lake of Fire. John tells of plagues that will be cast onto the world and he speaks of the final resting place of the non-believer. They will show the wrath of God’s judgment on the wicked. Lastly, John describes  the New Heaven and the New Jerusalem. There will be no tears, crying, or death!
