Overview of the Worlds Offset Time Zones

While most of the world is familiar with time zones that differ in increments of an hour, there are many places in the world that use offset time zones. These time zones are offset by a half-hour or even fifteen minutes off of the standard twenty four time zones of the world. The twenty four time zones of the world are based on fifteen degree increments of longitude. This is so because the earth takes twenty four hours to rotate and there are 360 degrees of longitude, so 360 divided by 24 equals 15. Thus, in one hour the sun moves across fifteen degrees of longitude. The offset time zones of the world were designed to better coordinate noon as the point in the day when the sun is at its highest point in the sky. India, the worlds second most populous country utilizes an offset time zone. India is a half-hour ahead of Pakistan to the west and a half-hour behind Bangladesh to the east. Iran is a half-hour ahead of its western neighbor Iraq while Afghanistan, just east of Iran, is an hour ahead of Iran but is a half-hour behind neighboring countries such as Turkmenistan and Pakistan. Australias Northern Territory and South Australia are offset in the Australian Central Standard Time zone. These central portions of the country are offset by being a half-hour behind the east (Australian Eastern Standard Time) coast but an hour and a half ahead of the state of Western Australia (Australian Western Standard Time). In Canada, much of the province of Newfoundland and Labrador are in the Newfoundland Standard Time (NST) zone, which is a half-hour ahead of Atlantic Standard Time (AST). The island of Newfoundland and southeastern Labrador are in NST while the remainder of Labrador along with neighboring provinces New Brunswick, Prince Edward Island, and Nova Scotia lie in AST. Venezuelas offset time zone was established by President Hugo Chavez in late 2007. Venezuelas offset time zone makes it a half hour earlier than Guyana to the east and a half hour later than Colombia to the west. One of the most unusual time zone offsets is Nepal, which is fifteen minutes behind neighboring Bangladesh, which is on a standard time zone. Nearby Myanmar (Burma), is a half-hour ahead of Bangladesh but an hour ahead of offset India. The Australian territory of the Cocos Islands shares the time zone of Myanmar. The islands of Marquesas in French Polynesia are also offset and are a half-hour ahead of the rest of French Polynesia.

Strontium Facts (Atomic Number 38 or Sr)

Strontium is a yellowish-white alkaline earth metal with atomic number 38 and element symbol Sr. The element is known for producing red flames in fireworks and emergency flares and for its radioactive isotope that is found in nuclear fallout. Here is a collection of strontium element facts. Fast Facts: Strontium Element Name: StrontiumElement Symbol: SrAtomic Number: 38Appearance: Silvery-white metal that oxidizes to pale yellowGroup: Group 2 (Alkaline Earth Metal)Period: Period 5Atomic Weight: 87.62Electron Configuration: [Kr] 5s2Discovery: A. Crawford 1790 (Scotland); Davey isolated strontium by electrolysis in 1808Word Origin: Strontian, a town in Scotland Strontium  Basic Facts There are 20 known isotopes of strontium, 4 stable and 16 unstable. Natural strontium is a mixture of the 4 stable isotopes. Properties: Strontium is softer than calcium and decomposes more vigorously in water. Finely divided strontium metal ignites spontaneously in air. Strontium is a silvery metal, but it rapidly oxidizes to a yellowish color. Because of its propensity for oxidation and ignition, strontium is typically stored under kerosene. Strontium salts color flames crimson and are used in fireworks and flares. Uses: Strontium-90 is used in Systems for Nuclear Auxilliary Power (SNAP) devices. Strontium is used in producing glass for color television picture tubes. It is also used to produce ferrite magnets and to refine zinc. Strontium titanate is very soft but has an extremely high refractive index and an optical dispersion greater than that of diamond. Element Classification: Alkaline earth metal Biological Role: Radiolarian protozoa belonging to the group Acantharea make their skeletons of strontium sulfate. In vertebrates, strontium replaces a small amount of calcium in skeletons. In humans, absorbed strontium is primarily deposited in bones. In adults, the element only attaches to bone surfaces, while it can replace calcium in growing bones of children, potentially leading to growth problems. Strontium ranelate can increase bone density and reduce the incidence of fractures, but it also increases the risk of cardiovascular problems. Topically applied strontium inhibits sensory irritation. It is used in some toothpastes to reduce sensitivity. While stable strontium isotopes present no significant health threat, the radioisotope strontium-90 is considered dangerous. Like the stable isotopes, it is absorbed into bones. However, it undergoes beta-minus decay and thus poses a radiation hazard.

In compression, the algorithm looks for repeating patterns in the source alphabet and encodes these patters as new symbols in a translated alphabet. The new alphabet is composed of symbols that are longer (composed of more bits) than the symbols in the source alphabet. The compression arises when repeating patterns in the old alphabet are replaced by a single symbol in the new alphabet. We will write a custom essay sample on The replacement is stored or any similar topic only for you Order Now The replacement is stored in a dictionary that contains all mappings of the old alphabet patterns into the new alphabet symbols. The decompression algorithm simply does the reverse process of the compression algorithm. The algorithm takes a look at the input stream in the new alphabet and looks up the dictionary for its corresponding pattern in the old alphabet. Unlike Huffman coding, LZW compression does not use probability analysis and computation on the source data, needing only to look at repeating patterns in the source alphabet. LZW works best on streams that contain multiple repeating patterns such as text files. Huffman coding on the other hand works best on streams where there is a disparity in relative frequencies between symbols. In LZW, a dictionary is used to map patterns in the old alphabet to symbols in the new alphabet, the dictionary being constructed from repeating patterns. In Huffman, symbol mappings are based on the frequencies of the symbols in the source alphabet. Additionally, the bit length of the new symbols in LZW is constant while the bit length for the new symbols in Huffman is variable, depending on the frequency of the source symbols. Wireless Mobile Ad-hoc Networks (MANET) and Wireless Sensor Networks are two similar kinds of wireless technology. A MANET is a self-configuring network the result being an arbitrary topology. There is no fixed infrastructure between the nodes and their only relationship to each other is their proximity to one another. However, that may not be true for sensor networks. Some sensor network protocols specify a specific topology. In the case of IEEE 802.15.4, it allows for two kinds of topologies, a ring topology and a peer to peer topology. Another difference is complexity. The nodes of sensor networks are generally much simpler than in MANETs. Sensor nodes typically include only a transceiver module for communication, a sensor and a microcontroller. This is because of the relatively simpler uses for the sensor such as data collection and gathering. In contrast, nodes of a MANET will generally be more complex, being made up of complete laptops, PDAs or other high level communication devices. A third difference is in the data rates. Sensor networks are generally low data rate systems while MANETs have higher data rates. Bit rates in MANETs like 802.11 are measured in Mbps while those in 802.15.4 and Zigbee are in kbps only. Fourth is power consumption, MANET nodes are designed to be mains powered or only to be reliant on batteries for a short amount of time (generally a few hours). On the other hand, sensor networks will generally use low power components to stretch the power of the battery for weeks or months on end. Lastly, in MANETs, nodes are envisioned to be constantly sending data to one another while in sensor networks, nodes are expected to be in a sleep or quiet mode for most of the time. This is due to the amount of data exchanged in MANETs compared to sensor networks which may only need to throw data to the server on specified times. If we take the example of the ZigBee sensor network protocol, we can see three layers from the OSI model at work in the ZigBee protocol. In the ZigBee protocol, its uses the IEEE 802.15.4 standard for the PHY and MAC portion of the DLL layer. The ZigBee specification on the other hand serves as the upper layers for the wireless sensor network. How to cite The replacement is stored, Papers

Arthur Millers The Crucible Explore the role played by Abigail Williams in the play. Is it possible to have sympathy for her character Essay Example For Students

Arthur Millers The Crucible: Explore the role played by Abigail Williams in the play. Is it possible to have sympathy for her character? Essay In this essay, I will be exploring Abigail Williams role in the play, showing how she makes the majority of other characters believe her lies and also stating whether in my view, it is possible to have sympathy for her character. First of all, I think that Abigail is a very manipulative character and this is shown in almost every passage of Arthur Millers writing. He describes her as a very innocent girl who is known by everyone. John Proctor cheated on his wife with Abigail and now she wants him all to herself. John Proctor is certain that he wants to stay with his wife, Elizabeth Proctor. Abigail is expressed as a character that can get anything she wishes. The way in which she does this is by acting the sweet innocent child that has no knowledge of the world or happenings, when really she is a conniving little cow. In the play, One passage that Abigail Uses is, Now look you. All of you. We danced. And Tituba conjured Ruth Putnams dead sisters. And thats all. And mark this. Let either of you breathe a word, or the edge of a word, about the other things, and I will come to you in the black of some terrible night and I will bring a pointy reckoning that will shudder you. And you know I can do it: I saw Indians smash my dear parents heads on the pillow next to mine, and I have seen some reddish work done at night, and I can make you wish you had never seen the sun go down! Now you-sit up and stop this! This is a very frightening and aggressive piece of writing. This shows that Abigail can be a very scary character, even at the tender age of 17, or around about. The exploration of Abigail Williams role in the play is to be the baddy, and create havoc. If Abigail didnt appear exactly as she does, in my personal view, the story would be horrendous. This is because almost all of the drama and tension is created in resolution to her actions, whether directly or indirectly. Abigails role is to erupt when anything is regaining normalness or anything looks like it will go back to the way it was. Abigail is the spark of a Volcano, because when she says that all of the wives of the men in the town of Salem are witches and she had seen them with the devil when she was brought to it, it causes the whole city to erupt like an exploding, destructive volcano. Abigail says, I look for John Proctor that took me from my sleep and put knowledge in my heart! I never knew what pretence Salem was, I never knew the flying lessons I was taught by all these Christian women and their covenanted men! And now you bid me tear the light out of my eyes? I will not, I cannot! You loved me, John Proctor, and whatever sin it is, you love me yet! John, pity me, pity me! She says this in response to John Proctor, who slept with her, only to turn her down and exclaim to her that he does not love her anymore. This is one of the points in the play when it shows that Abigail may have had a reason for what she did. John Proctor knocking her back, gives her a fire in her eyes and heart, to damage and hurt Proctor and his wife. Abigails phrase, put knowledge in my heart! means that she was a virgin before her and John had intercourse. This gives Abigail the reason throughout the story to be so mean and cruel. In a way, it is kind of like Miss Havisham in, Great Expectations, by Charles Dickens. This is because they have both been knocked back by men, their partners or such, and they go on to hate men and be evil people. Abigail says to reverend Hale on him asking her if she had sold her soul to the devil, I never sold myself! .u854318834363caad241a6f38c68f5def , .u854318834363caad241a6f38c68f5def .postImageUrl , .u854318834363caad241a6f38c68f5def .centered-text-area { min-height: 80px; position: relative; } .u854318834363caad241a6f38c68f5def , .u854318834363caad241a6f38c68f5def:hover , .u854318834363caad241a6f38c68f5def:visited , .u854318834363caad241a6f38c68f5def:active { border:0!important; } .u854318834363caad241a6f38c68f5def .clearfix:after { content: ""; display: table; clear: both; } .u854318834363caad241a6f38c68f5def { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u854318834363caad241a6f38c68f5def:active , .u854318834363caad241a6f38c68f5def:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u854318834363caad241a6f38c68f5def .centered-text-area { width: 100%; position: relative ; } .u854318834363caad241a6f38c68f5def .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u854318834363caad241a6f38c68f5def .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u854318834363caad241a6f38c68f5def .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u854318834363caad241a6f38c68f5def:hover .ctaButton { background-color: #34495E!important; } .u854318834363caad241a6f38c68f5def .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u854318834363caad241a6f38c68f5def .u854318834363caad241a6f38c68f5def-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u854318834363caad241a6f38c68f5def:after { content: ""; display: block; clear: both; } READ: A view from the bridge EssayIm a good girl! Im a proper girl! This is her basically saying that she thinks what he is saying to them is absolute rubbish. When the girls start exclaiming names, that they have seen with the devil, betty suddenly rises, which makes all of the people in the court think that it is a miracle of God, that the silent child wakes. In this play I think that there is a possibility to feel sorry for Abigail Williams, up until the point when people start to be hanged. I think that you could appreciate that Abigail has her own feelings and that the first man she has slept with is refusing to commit to her. You can be slightly sympathetic to her because she has been emotionally damaged by the point of Proctor having a sexual relationship with her. It is fine to say that she has been damaged by this experience, but you cannot expect anyone, however religious or forgiving, to forget about people that they love being hanged over crimes that they havent committed. Overall, I believe that up to a certain point in the play, you can sympathise with Abigail, but when she takes it to another level, you cant help but imagine the horror and utter stupidness of Abigail and her pathetic friends.
