Public Key Infrastructure - Case Study Example It is an accretion of technology, set-up and practices that empower extensive scale utilization of public key cryptography to give validness, confidentiality integrity, and non-repudiation facilities. It offers certainty of value in data sent and received naturally and the source and end of the information. Information that contains a public key structure can be used as evidence before the court of law. Components of the public key infrastructure maintain a high security of emails and other information components of an organization. The structural functioning of public key infrastructure is that it utilizes digital signatures, digital certificates, encryption, certificate revocation, authorities, and storage when sending an email (Chapple & Ballad, 2014). The functions of public key infrastructure are significant in the current work of technology. Some of its functions are public key cryptography, certificate issuance, certificate validation and certificate revocation. Public key cryptography is the utilization of a pair of algorithmically interrelated cryptographic keys. In the event, that one key is utilized to encrypt data, and then just the related key can decode that data. If a person knows one of the keys, they can without much strain ascertain what the other one is. A public key that is exposed to numerous people, but a private key is made known to its owner who upholds its secrecy and integrity strictly. Therefore, in a public system, it is important for one to have both the public key and the corresponding private key. The significance of the private key is that it enables one to prove who they claim to be. Public key cryptography is being applied in, amongst others, the IT security discipline data security. Data safety is c oncerned with all elements of securing electronic data resources against security threats. Public key cryptography is utilized as a system for guaranteeing the privacy, legitimacy and

Furthermore, the essay will include empirical studies of various artists and professionals in the field of fine arts and design. Through various reviews, I have learnt that painters and spatial designers are making immense contributions to the society. I have hence learnt that I will be in a position to create aesthetic appeal of homes. Through expertise in spatial art and interior design, I will be able to restore happiness and satisfaction to myself and the human race. Through appraisal of beauty, the field has enabled me to value specific objects in the society. I have also learnt the strategic use of interior design in drawing building plans taking into account interior spaces and probable rooming. In eventuality, they should award space appropriately to each section of a building. In my study of abstract paintings, I realized that they draw interests from everyone. On the contrary, I realized that a person who possesses a piece of an abstract painting could keep it for ages without having interpreted its meaning. Therefore, the value of such a work of art increases as time progresses in the sense that, it portrays not only its aesthetic value, but also the mysterious thought behind its conception. This misery behind the artistic works drew much interest from me, making me to relate commodities to their ideal values. Using an example of the value of money, I realized that everyone understands the importance of money and its value. However, people seem not to understand the real value of the money which is reflected by the purchasing potential as opposed to indicated numerical value indicated. In this respect, I have come to the conclusion that some abstract

International business short - Essay Example Regional integration further helps countries to benefit from absolute advantage on goods that they are able to produce at lower costs as compared to their neighboring countries. There are different theories that characterize regional integration which include removal of tariff barriers on trade. Through the removal of tariff barriers, companies are able to reduce the costs connected to marketing (Drexl, 2012, p.17). Another approach is adoption of external export policy that is common and this ensures that the integration does not discriminate on third parties conducting business with the member countries. Mobility is also enhanced through regional integration where movement of goods across borders is easy and fast (Drexl, 2012, p.21). Harmonization of policies related to economy further ensures that member countries have a common currency of conducting trade. Examples of regional integration include COMESA, ASEAN, Free Trade Area of Americans and African Economic Community (Sergi & Adekola, 2007, p.45). The different regional blocs prospective are to create a common market and boost their bargaining power in the international market. In summary, regional i ntegration enables member countries to expand their market and reduce costs related to exports due to reduced trade barriers. Culture is defined as the set of norms, beliefs, attitudes and values within a specific group of people (Deari, et al., 2008, p.18). Culture could be based on different aspects which include language, religion, race, ethnicity, income level and age. Culture is important in international business in that it influences how easy international businesses penetrate new market in foreign country. Culture is varying and changes from one region to the other and thus understanding these changes is important for international business managers (Ferraro, 2002,

Reacting against Victorian optimism and to the horrors of the 20th :: English Literature

Reacting against Victorian optimism and to the horrors of the 20th Century, William Golding chose to express his anti-Utopian views about humanity in Lord of the Flies (1954). Explore how Golding crafts his narrative in order to voice his philosophical views about man's essential illness. To what extent do you agree with his views? Golding's dystopian views of 'man's essential illness' are derived from his experience of 20th Century warfare. 'Lord of the Flies' is a fable in which Golding displays man's flaws inside a microcosm. This didactical work shows us that we have far to go, but there is hope. I will study his novel to discover his views, and will decide if I concur with them. Golding was born in Cornwall in 1911, and brought up in Wiltshire. His father was a teacher and a socialist and his mother actively supported the campaign for votes for women, so from an early age he was aware of social and political systems and their influence on people. During the Second World War, Golding joined the Royal Navy and took part in the sinking of the Bismarck and the Normandy landings on D-Day. His experience of the war had a profound effect on his view of the world. He learnt how brutal people can be. Although he was appalled by the evils of Nazism and the Third Reich, he said in an interview in 1963 that everyone was capable of inhumanity, not just the German or the Japanese. He saw Nazism as an evil system, and so horrifying that it could not be explained through reason alone. Later on he looked for an explanation in the nature of human beings, in their capacity for brutality and inhumanity. He read adventure stories such as 'The Coral Island', (1858), to his children, and wondered what would really happen to children stranded on a desert island. He took the idea of an innocent experience on an island and saw it in relation to the experience of Nazism and World War Two. In 'Lord of the Flies' Golding refers twice to R.M Ballantyne's 'The Coral Island'. The writer deliberately wrote 'The Lord of the Flies' in direct contest with the 'The Coral Island'. This is known because of an unpublished letter Golding wrote to his wife: 'Wouldn't it be a good idea to write a book about real boys on an island, showing what a mess they'd make?' Golding then went ahead and wrote the book to turn Ballantyne's simplistic assumptions and optimistic hopes on its head. Golding is even bold enough to use identical names as Ballantyne's for his main characters: Jack and Ralph in both books are protagonists, and are Reacting against Victorian optimism and to the horrors of the 20th :: English Literature Reacting against Victorian optimism and to the horrors of the 20th Century, William Golding chose to express his anti-Utopian views about humanity in Lord of the Flies (1954).

An Analysis of Witi Ihimaera’s Whale Rider Essay

In Witi Ihimaera’s novel â€Å"Whale Rider† we follow Rawiri as he goes through his life watching the growth, incidents and magic of his niece Kahu. Kahu is destined to be the next chief of the Maori in Whangara, New Zealand, a tribe that has descended from the legendary â€Å"whale rider.† However, Kahu is, as Nanny Flowers says, â€Å"Hungry for [her grandfather’s] love,† (Ihimaera 34) and struggles to receive it because she is a girl. The author presents this story through Kahu’s Uncle Rawiri’s point of view, and this outside view of Kahu is brilliant because it creates tension between what the reader, author, Rawiri and Kahu are thinking and allows the reader to fill in the gaps themselves. The story would lack suspense and motivation if we knew Kahu’s thoughts and would lose all aspects of mystery. Whale Rider creates a distorted medium between reality and the character’s minds, which is what keeps the reader guessing, second-guessing and questioning all the way up until the moment of truth in the end. Ihimaera makes it the reader’s job to presume Kahu’s thoughts as opposed to actually providing them. Rawiri comes into play in that that he has had a special connection with Kahu since her birth, and being in a first-person perspective with Rawiri makes Rawiri like the reader in that they mutually want all of the answers. If the novel were from the point of view of Kahu, the main focus, the plot would lose all curiosity. It was thought provoking and interesting to see Kahu strive for her grandfather’s acceptance from before she could even walk. If Kahu narrated then we wouldn’t be able to experience her development from birth, and would lose all of her toddler years. Those years keep Kahu a â€Å"question† and make us, like Rawiri, unable to wait for her to come of age and either become the whale rider or not. Whale Rider carries itself primarily on motivation towards â€Å"the end†. For the readers it is for the book’s climax. For Rawiri, Nanny Flowers, and even Kahu herself, it is for the end of Kahu’s childhood and for the answers to be revealed. Ihimaera does a great job of manipulating the motivation of the reader and intertwining it with the motivation of the characters while also leaving a prism in the middle of reality and literature where some of the  gaps and missing pieces are left to be filled with the reader’s empathy, curiosity and imagination.

Tips for a Successful Science Fair Project High school projects dont have to take longer than ones you might do in grade school or middle school, but youll be expected to use the scientific method.Demonstrations and models probably wont be successful unless they are simulations of complex behavior.A junior in high school should be capable of handling the design, implementation, and reporting for a science fair project. Its fine to ask for help with brainstorming, setting up an experiment, and preparing a report, but most of the work should be done by the student.You may work together with an organization or business for your project, which demonstrates organizational skills.The best science projects at this level answer a question or solve a problem that affects the student or society.

Green Rust - Interesting Iron Chemistry

Rust is the name given to a collection of iron oxides. Youll find rust in all situations where unprotected iron or steel is exposed to the elements. Did you know rust comes in colors besides red? There is brown, orange, yellow and even green rust! Green rust is an unstable corrosion product typically produced in a low-oxygen environment, such as on rebar in the chlorine-rich environment of seawater. The reaction between seawater and steel may result in [FeII3 FeIII (OH)8] [Cl ·H2 O]-, a series of iron hydroxides. Depassivation of steel to form green rust occurs when the ratio of concentration of chloride ions to hydroxide ions is greater than 1. Therefore, rebar in concrete, for example, may be protected from green rust if the alkalinity of the concrete is high enough. Green Rust and Fougerite There is a natural mineral which is the equivalent to green rust called fougerite. Fougerite is a blue-green to blue-gray clay mineral found in certain wooded regions of France. The iron hydroxide is believed to give rise to other related minerals. Green Rust in Biological Systems The carbonate and sulfate forms of green rust have been identified as by-products of ferric oxyhydoxide reduction in iron-reducing bacteria. For example, Shewanella putrefaciens produces hexagonal green rust crystals. Scientists speculate green rust formation by bacteria occurs naturally in aquifers and wet soil. How to Make Green Rust Several chemical processes produce green rust: Electrochemically oxidizing iron plates can form a green carbonate rust.Green rust may be prepared by bubbling carbon dioxide through a suspension of iron(III) hydroxide  Fe(OH)3  in  iron(II) chloride FeCl2.Green sulfate rust may result from mixing FeCl2 ·4H2O and NaOH solution to precipitate Fe(OH)2. Sodium sulfate Na2SO4 is added and the mixture is oxidized in air.
