10 Interesting Facts About New Orleans

New Orleans 404 is the largest city in the United States state of Louisiana with a 2008 population of 336,644 people. The New Orleans Metropolitan area, which includes the cities of Kenner and Metairie, had a 2009 population of 1,189,981 which made it the 46th largest metropolitan area in the United States. Its population dropped dramatically after Hurricane Katrina and the subsequent severe flooding hit the city in 2005.The City of New Orleans is located on the Mississippi River in southeastern Louisiana. The large Lake Pontchartrain also lies within the city limits. New Orleans is most well known for its distinctive French architecture and French culture. It is famous for its food, music, multicultural events and the Mardi Gras festival held in the city. New Orleans is also known as the birthplace of jazz. Legendary jazz figure Louis Armstrong was famously born here and honed his skills as a young musician in the citys clubs. The following is a list of 10  important geographic facts about New Orleans. The City of New Orleans was founded under the name La Nouvelle-Orlà ©ans on May 7, 1718, by Jean-Baptiste Le Moyne de Bienville and the French Mississippi Company. The city was named after Phillipe dOrlà ©ans, who was Frances head of state at the time. In 1763, France lost control of the new colony to Spain with the Treaty of Paris. Spain then controlled the region until 1801, at which time, it was passed back to France.  In 1803 the region encompassing New Orleans and surrounding areas was sold by Napoleon to the United States with the Louisiana Purchase. The city then began to grow considerably with a variety of different ethnicities.After became a part of the United States, New Orleans also began to play a large role in international relations as it developed into a large port. The port then played a role in the Atlantic slave trade but also the exportation of different commodities and the importing of international goods for the rest of the nation up the Mississippi River.Thr oughout the rest of the 1800s and into the 20th century, New Orleans continued to grow rapidly as its port and fishing industry remained important for the rest of the country. In the end of the 20th century, growth in New Orleans continued but planners became aware of the citys vulnerability to flooding after erosion of wetlands and marshes.In August 2005, New Orleans was hit by the category five Hurricane Katrina and 80 percent  of the city was flooded after a failure of the citys levees. 1,500 people died in Hurricane Katrina and much of the citys population permanently relocated.New Orleans is located on the banks of the Mississippi River and Lake Pontchartrain about 105 miles (169 km) north of the Gulf of Mexico. The total area of the city is 350.2 square miles (901 sq km).The climate of New Orleans considered humid subtropical with mild winters and hot, humid summers. The average July high temperature for New Orleans is 91.1 °F (32.8 °C) while the average January low is 4 3.4 °F (6.3 °C).New Orleans is known for its world-famous architecture and areas like the French Quarter and Bourbon Street are popular areas for tourists. The city is one of the top ten most visited cities in the U.S.The economy of New Orleans is based largely on its port but also on oil refining, petrochemical production, fishing and the service sector related to tourism.New Orleans is home to two of the largest private universities in the United States- Tulane University and Loyola University New Orleans. Public universities like the University of New Orleans are also within the city.

My Dog Seeka Essay Example For Students

My Dog Seeka Essay Our first family pet was a black lab/German Shepherd mix named Cheyenne. My parents adopted her as a puppy before I was even born, and she was considered a part of the family. She had black fur all over except for her tan underside, and her face resembled a raccoon. As far back as I can remember she was always very docile, and well behaved to the point we could let her go outside and call her back a few minutes later without having to worry about her running away. She was a part of our family for 10 years. Unfortunately, when we moved to Canada, we had to put her up for adoption as we couldnt bring her with us. Around the age of 6 we adopted another dog named Emily. She was a pure breed black lab, with pitch black fur all over. She was fairly violent, and we had a lot of trouble with her training, to the point where we had to keep her in a crate most of the time. We only had Emily for 2 years before we put her up for adoption. Around the same age we also had a few cats. Peaches, an over weight, orange cat originally belonged to us, but he got out one day and we were never able to keep him in the house again. Yet strangely enough, he never left the area, and even followed us when we moved a few miles down the street. Our other cat was named Sevens. She was mostly gray with a few darker gray stripes down her back. We never had Sevens spayed, and as a result she ended up have 3 litters of kittens throughout her life, but we never kept any of the kittens. It was never confirmed, but we always believed Peaches was the father. A slightly less memorable pet, but I will never forget was an oscar fish simply named Oscar. I mostly remember Oscar because we had a lot of fun feeding his minnows. We owned all of these pets throughout the first 9 or 10 years of my life, and around that time we moved to Canada. My parents wanted to make sure that we always had a family pet so they immediately went on a search. The first pet we owned in Canada was a golden retriever/beagle mix puppy named Tess. She was definitely more beagle, but she has pure golden fur. We also adopted a black lab named Sam shortly after. I really dont remember much about them aside from how much trouble we had with their house training. There was a very large field full of tall grass and weeds at the end of our street, and we would take them out there and let them run around and play for a while, which turned out to be a bad idea when one day they run pretty far out, too far for us to see, and eventually they were gone. They turned up in a kennel a few days later but we didnt have the money to get them back, so that was the last we saw of them. We waited a few months before we tried to adopt any new pets, but my father always knew exactly what he wanted. His favorite breed of dog were huskies, and we found a husky trainer a few hours north, and that is where we adopted Komo and Seeka, two pure breed huskies. Komo was the more traditional looking husky; a mix of thick black and white fur with icy blue eyes. He quickly grew attached to my father and he couldnt have been happier with the outcome. Komo was around eight years old, so he was usually very docile and enjoyed curling up on the couch with my father. Seeka was younger, somewhere around three, slender when compared to Komo, and had snow white fur with patches of brown. .u6579733ae246990199b935267b559e33 , .u6579733ae246990199b935267b559e33 .postImageUrl , .u6579733ae246990199b935267b559e33 .centered-text-area { min-height: 80px; position: relative; } .u6579733ae246990199b935267b559e33 , .u6579733ae246990199b935267b559e33:hover , .u6579733ae246990199b935267b559e33:visited , .u6579733ae246990199b935267b559e33:active { border:0!important; } .u6579733ae246990199b935267b559e33 .clearfix:after { content: ""; display: table; clear: both; } .u6579733ae246990199b935267b559e33 { 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; } .u6579733ae246990199b935267b559e33:active , .u6579733ae246990199b935267b559e33:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6579733ae246990199b935267b559e33 .centered-text-area { width: 100%; position: relative ; } .u6579733ae246990199b935267b559e33 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6579733ae246990199b935267b559e33 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6579733ae246990199b935267b559e33 .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; } .u6579733ae246990199b935267b559e33:hover .ctaButton { background-color: #34495E!important; } .u6579733ae246990199b935267b559e33 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6579733ae246990199b935267b559e33 .u6579733ae246990199b935267b559e33-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6579733ae246990199b935267b559e33:after { content: ""; display: block; clear: both; } READ: 4)The Application of Science to Engineering EssayShe had one brown eye and one blue eye, which I thought made her more unique. She was a beautiful dog, but when we first adopted her along with Komo, she was very shy. She would stay away from everyone, wouldnt really do much. One day, I stayed home sick, I was the only one home so my parents let me spend the day in their bed, and I kept Seeka in the room with me. After taking a nap, I woke up to see Seeka laying on the bed with me. She was so warm and soft, so I curled up with her, and from that day she was MY dog. She was still shy with the rest of the family, but she was always so excited whenever I was around. She would always follow me around, jump up to try and lick my face, it even got to the point where I could walk around the corner while someone was holding her, and she would start to whine until I came back around. I had my dad take apart my loft bed so she could sleep with me at night shortly after she grew attached to me. I remember during the winter, we would hook her leash up to a sled and she would pull me around the block until she tired herself out. This was the first time I ever had that â€Å"boy and his dog† kind of relationship with a pet. I loved Seeka, and she loved me. I never waned to lose her, but things took a bad turn far too soon. About a year and a half after we moved to Canada, and about a year after we adopted Komo and Seeka, my father was laid off. He tried to find another job, unfortunately, with no avail. We tried our best but we were evicted from our house, and at the time we had to move in with some relatives in New York until we could find a new house to move to. What made this worse was that there wasnt enough room in the house for Komo and Seeka, so we were afraid we would have to give them up. It was devastating, but we had one glimmer of hope that made everything better. The kennel we adopted them from promised that they would hold onto them and take care of them until we could take them back. It was sad saying goodbye to Seeka, but it was OK because it would only be a few months. Time had gone by, we moved into a new house, and it was time to go and get the dogs back. When we called the kennel, they very coldly told us they had sold Komo and Seeka, and told us they never made that promise. There was nothing we could do, because we never got it in writing so we had no way to prove it or even take any sort of legal action. I was crushed. At this point in my life, I had never lost a loved one, and never got this close to any of our other pets, so this was the worst moment in my life. Knowing that not only would I never see Seeka again, but that she was still out there somewhere made it even worse. I didnt know what to do, and no one had any answers. In the end, I could do nothing. I had to live with this now, and even to this day I still miss Seeka.

Lab Report Gas Laws Essay Example

Lab Report: Gas Laws Paper Obtain a reference of pressures effects on gas using Boles law using a gas sample of standard air within a syringe and measuring pressures increase and decrease in association to changing volume. Measurements are obtained through microbial sensors and graphed using microbial software where a correlation coefficient of P vs IN can be determined to represent pressure and volumes relationship to each other in the experiment. Procedure / Observations: Entered microbial gas laws program, chose Charles Law and labeled y-axis as temperature variable in Celsius, and x-axis as volume in ran. Read the capillary bees gas bubble at the base of the bubble, recorded as 5. 8. Then placed the sealed end of a capillary tube into a 400 ml beaker 2/3 full of room-temp water. The capillary tubes plug keeps the small amount of air trapped between plug and sealed end. The weight of the plug plus the constant ATM applied maintains a constant pressure on the trapped gas. Turned on hot plate to setting 5, placed 400 ml beaker of water with capillary tube onto hot plate allowing temperature of water to rise to 80 C while stirring occasionally. Once water temperature was found to have reached desired temperature of 80 C the capillary tubes gas bubble was read at the top of bubble in order to deduct from initial reading to determine the changes forced on gas bubble from increase in temperature, the capillary tubes gas bubble read 3. 4 at the top, then deducted the 3. 4 reading at the top of gas bubble from the 5. 8 reading taken prior to heating and from the base of the gas bubble. The difference was 2. 4, which was entered manually into microbial, temperature was read simultaneously as data of gas change was entered into microbial.

Removed the beaker containing 400 ml water, with capillary tube still inside tit sealed end still resting on bottom of beaker, from the hot plate to speed cooling process because the hot plate, although turned off was still heating the water. One minute passed, gas bubble read 3. 4, deducted again from bottom reading of gas bubble taken at the beginning of experiment; difference was a staggering 2. 4, no change. Added approximately five circular chips of ice to water in 400 ml beaker, allowed chips to dissolve within one-minute time frame, read top of gas bubble in capillary tube to be 3. 5, then deducted from our initial base reading at the beginning of 5. And found the difference to be 2. 3. Input data to microbial and temperature was read simultaneously as enter was hit. Added another 5 circular chips of ice to ice to water in the 400 ml beaker, allowed ice to melt while stirring during one-minute interval. Measured top of capillary tubes gas bubble to be 3. , deducted from initial reading at base of gas bubble, in the beginning of experiment of 5. 8, and found a difference of 2. 3. A change had not occurred. Repeated the process of adding ice to water, assisting ice to melt completely by stirring, measured change in gas bubble formed inside capillary be and input data into microbial until the temperature reached 5 degrees Celsius. Please reference attached graph labeled Charles Law. Used data obtained from microbial software to determine Correlation coefficient (V vs T) of R = 0. 92. Were able to determine that absolute zero of experiment by taking the product of 122. 405 (y axis) and 0 (slope intercept), with the sum of -209. 54 (x axis) to find our absolute zero of -209. 54 degrees C. Using the actual/theoretical percent yield equation was able to find the percent error of 23%. Boles law experiment started with opening a new microbial program within in he gas law program labeled Boles law. Set pressure plot to y-axis with factory calibration, set volume plot to the x-axis in ml. Connected syringe to pressure connection in from of microbial. Set syringe to 30. 0 ml, taking into account the 4 ml of sample gas contained in the hose for a total gas quantity of 34. 0 ml. Took measurements of pressure at volume settings from 34 ml, 29 ml, and 25 ml while applying pressure, and then measured from 25 ml, 29 ml, and 34 ml while pulling and applying suction. Microbial measured the pressure and volume changes, please reference attached graph labeled Boles law. Found the correlation coefficient (P vs I/V) to be . 999, information was given as a quantitative value from microbial. Data: Please see attached graph labeled Charles law -209. 54 Please see attached graph labeled Boles law Data Analysis: Charles law experiment and data show that there is an equal relationship between temperature and volume in relation to gas. When temperature increases, so does the volume. Similarly, when temperature decreases so does the volume. It makes sense since on a molecular level the gas partials are moving faster at higher temperatures, thus causing an expansion of the gas to occur as observed in the increased gas bubble inside the capillary tube. Boles law experiment and data displayed similar findings where the pressure and suction were applied and same amount of energy was recorded being placed on the gas at the same measured intervals without change. The graph displayed a visual of the inverse relationship between pressure and volume in relation to gas laws and how where one increases and the other decreases. Conclusion: Experiment was intended to find a reference of temperatures effect on gas using Charles law when heating a capillary tube in water on a heated hot plate. Then, cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microbial sensor and graphed using microbial software. A final determination of experiments determined absolute zero versus actual absolute zero will be calculated to determine percentage of error in experiments data using Charles quantitative law of VI/TO=V/TO. We were able to determine the percent error to be 23% and observe a linear display of the relationship between temperature and volume where as one increases, so does the other. The same relationship was observed in the decrease of temperature and volume. Experiment was meant to obtain a reference of pressures effects on gas using Boles law using a gas sample of standard air within a syringe and measuring pressures increase and decrease in association to changing volume. Measurements are obtained through microbial sensors and graphed using microbial software where a correlation coefficient of P vs IN can be determined to represent pressure and volumes relationship to each other in the experiment. Found that pressure and volume are inversely proportionate to each other, while one doubles, the other halves.

Analysis of Ceremony by Leslie Marmon Silko essays

Analysis of Ceremony by Leslie Marmon Silko essays In the novel, Silko explores the gender roles of four women and the significance to the development and actualization of Tayos character. These four women are Tayos birth mother, Auntie, old Grandma, and Tseh (a Montano). Because Tayo is of mixed ancestry, half white and half Native American, Tayo discovers he has a natural cultural flaw imposed upon him at birth, which would linger and expand into adulthood. At four years old, Tayos birth mother left him with his Aunt and Grandmother so they could raise him as their own due to her alcohol addiction and vicarious life-style. He didnt remember much: only that she (mother) had come after dark and wrapped him in a mans coat it smelled like a man and that there were men in the car with them . . . he clung to her because when she left him, he knew she would be gone for a long time . . . there were tears all over his face and his nose was running (Silko 65-66). Nonetheless, Tayos sense of emptiness and abandonment began. Auntie raised Tayo and was the mother figure he lacked. However, Auntie reluctantly accepted this responsibility because she could not bear to raise a child that brought the reservation shame by his mothers mistake. On the other hand, Auntie willingly accepted Tayo to conceal the shame of her younger sister (Ibid 29). This contradiction, made Auntie hesitant toward Tayo as he was not her real son and was also a half-breed. For Tayo, this only added to his feeling of displacement and the feeling of being invisible (Ibid 14). Auntie would give her affection and attention to her natural son Rocky, and would intentionally make Tayo feel excluded. It was a private understanding between the two of them. When Josiah or old Grandma or Robert was there, the agreement was suspended, and she pretended to treat him the same as she tr...

Geothermal Energy - Tapping the Earths Heat Supply

Geothermal Energy - Tapping the Earths Heat Supply As the costs of fuel and electricity rise, geothermal energy has a promising future. Underground heat can be found anywhere on Earth, not just where oil is pumped, coal is mined, where the sun shines or where the wind blows. And it produces around the clock, all the time, with relatively little management needed. Heres how geothermal energy works. Geothermal Gradients No matter where you are, if you drill down through the Earths crust you will eventually hit red-hot rock. Miners first noticed in the Middle Ages that deep mines are warm at the bottom, and careful measurements since that time have found that once you get past surface fluctuations, solid rock grows steadily warmer with depth. On average, this geothermal gradient is about one degree Celsius for every 40 meters in depth or 25 C per kilometer. But averages are just averages. In detail, the geothermal gradient is much higher and lower in different places. High gradients require one of two things: hot magma rising close to the surface, or abundant cracks allowing groundwater to carry heat efficiently to the surface. Either one is sufficient for energy production, but having both is best. Spreading Zones Magma rises where the crust is being stretched apart to let it rise- in divergent zones. This happens in the volcanic arcs above most subduction zones, for instance, and in other areas of crustal extension. The worlds largest zone of extension is the mid-ocean ridge system, where the famous, sizzling-hot black smokers are found. It would be great if we could tap heat from the spreading ridges, but that is possible in only two places, Iceland and the Salton Trough of California (and Jan Mayen Land in the Arctic Ocean, where no one lives). Areas of continental spreading are the next-best possibility. Good examples are the Basin and Range region in the American West and East Africas Great Rift Valley. Here there are many areas of hot rocks that overlie young magma intrusions. The heat is available if we can get to it by drilling, then start extracting the heat by pumping water through the hot rock. Fracture Zones Hot springs and geysers throughout the Basin and Range point to the importance of fractures. Without the fractures, there is no hot spring, only hidden potential. Fractures support hot springs in many other places where the crust is not stretching. The famous Warm Springs in Georgia is an example, a place where no lava has flowed in 200 million years. Steam Fields The very best places to tap geothermal heat have high temperatures and abundant fractures. Deep in the ground, the fracture spaces are filled with pure superheated steam, while groundwater and minerals in the cooler zone above seal in the pressure. Tapping into one of these dry-steam zones is like having a giant steam boiler handy that you can plug into a turbine to generate electricity. The best place in the world for this is off limits- Yellowstone National Park. There are only three dry-steam fields producing power today: Lardarello in Italy, Wairakei in New Zealand and The Geysers in California. Other steam fields are wet- they produce boiling water as well as steam. Their efficiency is less than the dry-steam fields, but hundreds of them are still making a profit. A major example is the Coso geothermal field in eastern California. Geothermal energy plants can be started in hot dry rock simply by drilling down to it and fracturing it. Then water is pumped down to it and the heat is harvested in steam or hot water. Electricity is produced either by flashing the pressurized hot water into steam at surface pressures or by using a second working fluid (such as water or ammonia) in a separate plumbing system to extract and convert the heat. Novel compounds are under development as working fluids that could boost efficiency enough to change the game. Lesser Sources Ordinary hot water is useful for energy even if it isnt suitable for generating electricity. The heat itself is useful in factory processes or just for heating buildings. The entire nation of Iceland is almost completely self-sufficient in energy thanks to geothermal sources, both hot and warm, that do everything from driving turbines to heating greenhouses. Geothermal possibilities of all these kinds are shown in a national map of geothermal potential issued on Google Earth in 2011. The study that created this map estimated that America has ten times as much geothermal potential as the energy in all of its coal beds. Useful energy can be obtained even in shallow holes, where the ground isnt hot. Heat pumps can cool a building during summer and warm it during winter, just by moving heat from whichever place is warmer. Similar schemes work in lakes, where dense, cold water lies on the lake bottom. Cornell Universitys lake source cooling system is a notable example. Earths Heat Source To a first approximation, Earths heat comes from radioactive decay of three elements: uranium, thorium, and potassium. We think that the iron core has almost none of these, while the overlying mantle has only small amounts. The crust, just 1 percent of the Earths bulk, holds about half as much of these radiogenic elements as the whole mantle beneath it (which is 67% of the Earth). In effect, the crust acts like an electric blanket upon the rest of the planet. Lesser amounts of heat are produced by various physicochemical means: freezing of liquid iron in the inner core, mineral phase changes, impacts from outer space, friction from Earth tides and more. And a significant amount of heat flows out of the Earth simply because the planet is cooling, as it has since its birth 4.6 billion years ago. The exact numbers for all these factors are highly uncertain because the Earths heat budget relies on details of the planets structure, which is still being discovered. Also, Earth has evolved, and we cannot assume what its structure was during the deep past. Finally, plate-tectonic motions of the crust have been rearranging that electric blanket for eons. The Earths heat budget is a contentious topic among specialists. Thankfully, we can exploit geothermal energy without that knowledge.

Chinese Painting- Qi Baishi Essay Example | Topics and Well Written Essays - 1000 words

Chinese Painting- Qi Baishi - Essay Example Qi painted Lotus flower with cicada with great independence that few artists portray. He used swift, sure and spontaneous brush strokes to depict the nature and appearance of the lotus flower. It is imperative that Qi’s greatness in using a brush to draw swiftly thin lines that seem to mature with old age helped in designing lotus flower with cicada paint. Moreover, it is essential to note that Qi perfected his ability to use the brush in designing strokes that depict tiny shapes of flowers and insects during his old age. It is indispensable that Qi’s spontaneous ability to use brush effectively in making perfect thin strokes made him the most celebrated artist in China. He combines simplicity, forceful brush, and a strong sense of naivety to design the most powerful image of Lotus flower that gives the viewer a natural feeling. In addition, Qi’s powerful use of the brush in painting tiny diagrams depicts the beautiful image of brown hairy nature of lotus seed like parts. He perfectly designs the brown hairy parts in such a manner that they reflect a mature flower. Qi then paints a tiny cicada insect on the surface of the brown hairy part, a design that gives the painting natural coexistence. Lotus flower with cicada painting is invaluable in depicting the great style and commitment Qi Baishi showed on his works. The paintings’ natural feeling that results from the close interaction between cicada and lotus flower enable the viewer to reflect on Qi’s feeling and mood while meditating on natural coexistence.
