Solar Thermal Energy - Essay Example The first component of a solar thermal system is the solar collector. This is usually installed on the rooftop. It represents the major component of the system. It is made up of specially coated tubing that absorbs the solar radiation and converts it into heat. There is a need to minimize thermal losses. This need is addressed by embedding the tubing in a heat-insulated container that is equipped with a transparent cover. Inside this tubing, a heat transfer fluid flows inside and circulates between the collector and the hot water tank. This water is normally a mixture of water and an anti-freeze that is ecologically safe. The key part of the solar collector is the absorber, which comprises of several narrow metal strips. Typically, absorbers are made of aluminum or copper. These are good conductors of heat. These absorbers are often black so as to enable a high degree of light absorption. In order to reduce the loss of heat energy through heat emission, efficient absorbers have selective surface coating which enables the conversion a substantial amount of solar radiation into heat. This also reduces heat emission. The degree of absorption that can be provided by usual coatings is about 90% (Solar-is-Future.com 1). Selective coatings can also be applied using galvanizing, and such coatings include black nickel, black chrome, and aluminum oxide with nickel. As such, there are different types of solar collectors which include flat-plate collectors, parabolic collectors, and evacuated-tube collectors.

Review of Renaissance Architecture Styles

Review of Renaissance Architecture Styles Throughout the past years the emergence of architecture have gone through various evolutionary phases .The philosophy of Architecture produced with time two major branches which is the basic Renaissance and Baroque architecture. The development of Architecture from basic Renaissance form which indicates having the characteristics of dignity and formality shown through symmetry and that to have an available space for rational engagement with the divine which can be asserted that it certainly provides a rational engagement with architecture which is a more effective means to comprehend and understand architectural form than the Baroque form which contrarily presented the beginning of new dynamic, fluid and theatrical approach to architecture that was designed to impact directly upon emotional modes of engagement. The Baroque architecture which was originally linked to the counter reformation which is a movement within the catholic church to rebuild itself to respond to the Protestant c hurch and its embellishments were more reachable to the feelings and power of the Italian church which formed a new style, whereas Renaissance was a mixture of religious and secular force and withdraw the prosperity and strength of the Italian churches. From the 14th to the 17th century In Italy ,the city of Florence specifically is where the launch of Renaissance architecture which is also known as ‘Rebirth’ or ‘Revival’ of the Roman classic Arts had firstly began and later was distributed to the rest of Europe. Symmetry ,geometry, proportion and regularity of elements are they are shown in Ancient Roman architecture is what specify the Renaissance style. However, in the city of Florence , architects and artists demonstrated their support through their progress of new shapes of painting, sculpture and architecture, similar to seeking of prestige and position through their assistance of art and letters by the bankers and rich merchants. Hence ,As time passed by Renaissance Architecture has evolved and went through multiple stages .At first it has gone through the Early period which is the first transition period. Secondly comes Proto-Baroque which is before baroque or in other words High renaissance .Finall y It evaluated to Baroque period. Baroque architecture began in late 16th century in Italy that turned Renaissance architecture into a philosophical and imaginative in a theatrical fashion way often to express an imaginative idea. Lights and dramatic intensity is used also to represent Baroque architecture. Bernini and Borromini are the first two major architects that developed Baroque period as Bernini was the first one to evolve many sculptures into his buildings and the Francesco Burromini came to Italy to learn from Bernini. However, every style of Architecture has its own characteristics, materials, elements and shapes and different aims, but it is supported that approaching architecture with Renaissance style tends to be more engaging with architecture and understanding it and representing it in a right form than Baroque style. Late Roman buildings, particularly Donato Bramante’s St. Peters Basilica Tempietto in Rome its design attains a colossal unity that was not known before and hence can be considered as ancestor to baroque architecture. Donato Bramante was an Italian architect, who introduced Renaissance architecture to Milan and the High Renaissance style to Rome, where his plan forSt. Peters Basilica formed the basis of the design executed by Michelangelo. Donato Bramante Tempietto in Rome represent perfectly the Renaissance style of architecture The tempietto identified the start of the Renaissance in Rome in 1502, when a sanctuary to represent where saint peter was killed was requested from Alexander to be built allegedly .Bramante made his building to symbolize the Christian reference for tradition and platonic preference for the early church. The building is surrounded by a one-story Doric colonnade with entablature and balustrade and a 2-story cylinder covered by a hemispherical dome Bramante’s St.Peter scheme symbolized a building on the buildup of the Baths of Diocletian covered by a dome similar to that of the Pantheon. Began in April 1506. Nearly all the vital architect of the 16th and 17th had been altered by the same time that the church was fully adjusted. Renaissance architecture in both of these buildings tends to having planar classicm in which its walls are decorated with culomns ,pediments,and blind arches of small physical depth and that serves as flat canvases for a classical inveer ,which serves to split a wall into a precise and neat form ,contrarily in Baroque architecture the walls are deeply chelised and curved which treats as undulating whole .Furthermore, St Peter’s basilica and Donato Bramante’s Tempietto in Rome have Faà §ades that are symmetrical around their vertical axis. A systenm of pilasters ,arches and entlabatures which form a proportional surmount the facades and the columns and windows demonstrate progression toward the centre.In contrast Buildings such as John Balthasar Neumann’s Pilgrimage Church of Vierzehnheiligen in Bamburg, Germany the facades consisted of many curves, Baroque pediments (which is the triangular area between the rooftop and the edge of the roofs) were often highly de corated. Scrolls and gilded formed the tips sometimes. This is a photo for John Balthasar Neumann’s Pilgrimage Church of Vierzehnheiligen in Bamburg, Germany which represent the Baroque architecture The Baroque style has its unique oval shape and took the advantage of marbles, bronze and gilts in abundance of the interior and sometimes the interiors are covered by multiple gilded puttos and life sized ones. Using an art technique called as ‘‘Trompe l’oeil’’ painting including strongly realistic imagery hence to create the optical vision and illusion for objects to be visible in three dimensions the ceilings and domes of the baroque architecture were formed ,instead of being an ordinary two dimensional painting . The major role that Baroque architecture acted upon was the call for an architecture that is both reachable and accessible to feelings and emotions and also a shown statement of wealth and power of church. The facades consisted of many curves, Baroque pediments (which is the triangular area between the end of the roofs and the rooftop) were usually extremely decorated. The tips were sometimes turned into scrolls and gilded. A listed featu res of baroque architecture would include more curves rather than straight lines , decorative columns instead of a supportive one and twisted in shape as well , detailing with a high sense of decoration , applying the appearance of moving and continuous flow as well , along with an abundance of windows , and a lot of paintings blending with the architecture. The church was constructed between the year of 1743 to 1772 along with it unique design in the interior which strongly reflect the baroque architecture. The plan of the church shows the church has layout which is considered to be a complex of highly divided spatial arrangement in a Latin cross form, along with a series of ovals that divides a large series of ovals that’s perpendicular to it. Moving on to the ceiling, it’s broken up with huge windows that allow the space to be exposed to directional light. Combining all this together which is the amount of light coming from the windows and the flawless stucco work d one by the architects, created an amazing and simple in terms of a transporting interior which has been called Gods Ballroom .As a person approaches the church he or she will witness a wonderful sandstone faà §ade resembling a glorious baroque style along with an appealing and warm hue. In conclusion, Baroque architecture which considered to be related to emotional engagement, this style or architecture concentrate and give more attention to decoration more than support of the structure, curves rather than straight lines, and emphasis on the appearance of movement all along the church. Although baroque has barrows many features from the mannerism and renaissance, but at the same time there is a lot of differences found between these two styles of architecture. In indicating those differences u will conclude that renaissance is more based on realism and being straight, as well as having the characteristics of dignity and formality shown through symmetry and that to have an available space for rational engagement with the divine which can be asserted that it certainly provides a rational engagement with architecture, while the baroque style concentrates more in being complex and in a flow. Giving those factors renaissance architecture can be considered more convincing in terms of architectural aspects due to the high level of stability and proportionality which reflects the concept of power and routine which is needed in places like churches

The Extraordinary Family in Judith Guests novel, Ordinary People :: Judith Guest Ordinary People Essays

The Extraordinary Family in Judith Guest's novel, Ordinary People    Judith Guest's novel Ordinary People evinces some main principles of the modernist literary movement, such as the philosophy that modern man is beset by existential angst and alienation. According to Carl Marx, a renowned existentialist, alienation, as a result of the industrial revolution, has made modern man alienated from the product of his own labor, and has made him into a mechanical component in the system. Being a "cog in the wheel" prevents modern man from gaining a sense of internal satisfaction of intellectual and emotional pleasure. Further more, according to Sigmund Freud, there are two pleasures, work and love. Consequently, Freud would say that being disconnected from pleasure from work, half of the potential for psychological fulfillment would be lost. Modern man is suffering from alienation as a result of large institutions, and as individuals, modern man neither feels that they are part of them nor can understand them. Additionally, the existentialists say , man is shut out of history. Modern man no longer has a sense of having roots in a meaningful past nor sees himself as moving toward a meaningful future. The modern man also suffers from alienation in his relationships with other people. Since he lives life not authentically and not knowing who he is, he cannot relate to others authentically. Hence, there are no real relationships at work and there are no real relationships of love. Also, according to Sartre, modern man is absolutely not a victim of his environments, of his childhood, and the circumstances in his life. The events in life are only neutral and since modern man is free, he chooses the meanings of the facts of his life. Modern man lives in a constant state of existential angst, which is dread of the nothingness of human existence and the fact there is no underlying purpose to human existence or set of objective truths or morals by which to navigate life. According to Martin Heideggar, German existentialist philosopher, the unaware person tries to escape the reality of death by not living life to the fullest. However, death can be the most significant moment for the individual, his defining moment of personal potential, if accepted and confronted squarely will free the individual from anxiety of death.

Air Forces Northern incident awareness and assessment playbook Essay

Ethics Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The United States Northern Command (USNORTHCOM) is the combatant command that is responsible for security and defense. They conduct Defense of the Civil authorities through providing capabilities to the DOD, Department of Defense from their land, air and sea components in support of the leading federal policies geared towards responding to any homeland security threat.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Among the capabilities that the DOD brings to their operations is the ISR and IAA. There is no difference between these two terms only that the term IAA has just been coined by the USNORTHCOM to denote the application of ISR when it is applied domestically to support the homeland security. The ISR operation mainly consist of flying both manned and unmanned platforms which are set to revolve over the battle field top provide a clear picture of the situation underneath. During the wartime, this picture could include the location of roads and deposition of the enemy and also the information that may be required so as to target the enemy. ISR provides a clear picture of situational awareness that could not only be used strategically to gain the full picture but also tactically to gather intelligence information that are useful in engaging individual targets. The situation awareness that is provided by the IAA/ ISR becomes a significant force m ultiplier which the commanders have been known to highly rely on.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There are many obstacles to realizing full potential for the ISR in homeland security. Currently there is statutory, doctrine, ethical and policy obstacles that exist to prevent ISR from reaching their full capacity for the homeland security provision.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Improved doctrines will see the department of Defense improve their ability to deliver IAA capabilities to the local, tribal, state and also the federal entities. The consumers all over the country and also the whole world will benefit from improved IAA capabilities.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The most significant ethical issues come secondarily where IAA capabilities are employed domestically. This is because it is known that all the American citizens enjoy freedoms of privacy, expression and they expect this to be fundamental and be respected in the best way possible. The American citizens highly value their freedoms and hence loath ideas that seem to threaten their constitutional protection.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In publicizing the use and purpose of IAA, I think there is a big ethical consideration in it because the citizens will get to know the function of IAA and how they function. They will not think that their freedoms are being infringed on but know that this is a military operation and that is how they are and should be carried hence in so doing, there will be no blame game between the government and the citizens.

Catcher in the Rye and Atigone

In the novel The Catcher in the Rye, and the play Antigone both main characters Holden and Creon are alienated or isolated from society. Through their journey they both develop the theme which is wisdom is gained through suffering and experience. J. D. Salinger’s novel ‘Catcher in the Rye’ portrays to the reader a protagonist named Holden Caulfield who desires independence and feels that the world is an inhospitable place, that he holds contempt for, Holden like many teenagers seeks a sense of identity but does not look for it through his connections with others.The book highlights this and his issue of identity is explored through Holden, himself, who can be correlated to other people living in forced isolation and alienation. Holden constantly labels â€Å"phoney-ness† on the adult world and forces self alienation as a way of self protection for himself to further illustrate his independence from a world he is not connected to. In the drama â€Å"Antigon e† by Sophocles we can see that Creon is also the protagonist. Creon is obsessed with greed and power. The play highlights this by capturing the controlling and manipulative ways of Creon’s personality.We can see that he is not directly wanting to be alone like Holden but that he doesn’t care about anyone else other than himself. This is self inflicting insolation, because no one will what to endure his presents. This help’s develop the theme because we can see both of the characters flaws and how they are going to grow. Holden is a compelling character, because we are not sure what he is going to do next. He purchased a red hunting hat that will make him stand out in a crowd, or protect himself from the outside world.He wears a hunting hat to show his uniqueness and isolates him self to portray that he is better than others and above interacting with them. In the beginning on the novel we see that the hat is used more frequently, to hide his true emotions . He tends to wear his hat when he is alone and thinking to himself. But he did wear it in a crowd of people so no one would talk to him. As he is in New York he tends to stop wearing the hat so often this meaning that he is growing up and maturing. Then eventually he even gives the hat to Phoebe showing that he is now an adult.There are many conflicts that Creon has to over come before he realizes that he is not the only person he truly cares about. Creon puts himself at a position of power, he go against his word saying that he would listen to the people of Thebes. Now he is going to send people to death even if they are listening to the gods. Because Creon is at a postison of power he can do whatever he wants even though it is pushing people away from him and causing him to be isolated. At the end of the play Creon finally realizes that just because he has power does not mean that everyone will love him, and he is left alone.This helps develop the theme because we can see that bo th characters are suffering in their own way. Holden is suffering with letting people in and not being able to show emotion. He is gaining knowledge through his own experiences and able to see that the adult world is not so bad after all. Creon had to also learn from his own experiences. Creon’s tragedy is his inability to recognize that anyone else can be right and his failure to acknowledge a higher good than that of the state. He only realizes when it is to late, when his loved ones were no longer with him.Holden often reaches out to people but sabotages potential relationships by making awkward and odd comments or actions. Holden is terrified to make a connection with someone knowing that the people he love often abandon him: Allie, D. B. , his parents. â€Å"Where do the ducks go? † is a question that he often asks to the taxi driver. This is a symbol of growth and maturity because he can see that not everything will leave forever like Allie. The ducks will come b ack and so will the people in his life. Holden thinks he wants to find someone to share intimacy with but truly what he needs is a good friend, someone who he can talk.This person in the novel is his sister the one who he truly cares about Phoebe. She is like a rock for him, even though she is much younger than him she acts as the adult in the relationship. She helps him grow and mature into a young adult. Unlike Holden, Creon is in love with power. He puts his love for his country above the love for his family He'd rather kill Antigone to uphold his law and win the respect (or fear) of people of Thebes than pardon his niece and one of his last living relatives. When he sends Antigone to her death he has an argument with his son Haemon.Creon is now killing the love of his son’s life for his own love of power. He tries to take back what he has done but it is to late, Antigone, Heamon, and Eurydice are now dead. Creon had cause his own son and wife to die because of his love fo r power. Love helps develop the theme because we reach out for people and we need them to live normal social lives. Without these life experiences how are we able to mature and grow as a person. You may have to suffer before you can see the growth. â€Å" Of happiness the crown and chiefest part is wisdom, and to hold the Gods in awe.This is the law that , seeing the stricken heart of pride brought down, we lean when we are old. † ( Chorus, p 162, text) We can only grow wiser through experience as we can see through both Holden and Creon. With both character’s they have to learn to let people in to have an opinion. That it is ok to stand out, but what will you do with your power? And to love the ones who love you. Without them you will be nothing in the world. Wisdom is gained through suffering and experience because without experience we would never grow as a person. Comparative Essay
