Rappaccini`s Daughter Rappaccini`s Daughter is gothic story written by Nathaniel Hawthorn in 1844.the story begins with a young man Giovanni who comes to Padua to study medicine at the university of Padua .He rents a room a ‘’high gloomy chamber’’ above a magical garden .The garden belongs to Dr. Rappaccini who lives with his own daughter ,Beatric who has been poisonous by his father .Giovanni sits by window which overlooks to the garden ,he is fascinated by garden which are full of strange flowers and plants .One day he is attracted by Rappaccini`s daughter Beatric He falls in loves with her but he is warned by his father`s freind professor Baglion to stay away from her because of her poisonous nature.So†¦show more content†¦Another theme of story is about human lust for power. Rappaccini uses science as vehicle for power over nature, through Beatric and the garden .He just, for the sake of power through science ,treats with Beatric and the plants.Touching nothing directly ,only looking and tending from distance. Baglioni also is represented a person who wants to win Dr.Rappaccini so he decides to kill Beatric.And Giovanni is not the person who truly loves Beatric .He loves her as he wants Beatric to be not as she is. Beatric is the only human who establish real love and who wants to love and be loved. Giovanni is the young protagonist. That he views the garden from his â€Å"lofty window† suggests his perspective on the complexity of good and evil embodied in Beatrice . When he first begins to understand that she is dangerous, he dismisses his suspicions as â€Å"fantasy†; however, as he becomes more concerned with himself than with her, he eventually calls her a â€Å"poisonous thing† who has contaminated him, making him â€Å"as hateful, as ugly, as loathsome and deadly a creature† as she. By the end of the story, his selfishness completely blinds him to her goodness, and as a result, he gives her the antidote provided by Baglioni, in this way hoping to â€Å"redeem† her from her evil nature and save her for a life of love with him.

Meaning of the Crude Birth Rate and Crude Death Rate

The crude birth rate (CBR) and crude death rate (CBR) are statistical values that can be used to measure the growth or decline of a population. Definitions The crude birth rate and crude death rate are both measured by the rate of births or deaths respectively among a population of 1,000. The CBR and CDR are determined by taking the total number of births or deaths in a population and dividing both values by a number to obtain the rate per 1,000. For example, if a country has a population of 1  million, and 15,000 babies were born last year in that country, we divide both the 15,000 and 1,000,000 by 1,000 to obtain the rate per 1,000. Thus the crude birth rate is 15 per 1,000. The crude birth rate is called crude because it does not take into account age or sex differences among the population. In our hypothetical country, the rate is 15 births for every 1,000 people, but the likelihood is that around 500 of those 1,000 people are men, and of the 500 who are women, only a certain percentage are capable of giving birth in a given year. Birth Trends Crude birth rates of more than 30 per 1,000 are considered high, and rates of less than 18 per 1,000 are considered low. The global crude birth rate in 2016 was 19 per 1,000. In 2016, crude birth rates ranged from 8 per 1,000 in countries such as Japan, Italy, Republic of Korea, and Portugal  to 48 in Niger. The CBR in the United States continued  trending down, as it did for the entire world since peaking in 1963, coming in at 12 per 1,000. By comparison in 1963, the worlds  crude birth rate hit more than 36. Many African countries have a very high crude birth rate, and women in those countries have a high total fertility rate, meaning they give births to many children in their lifetime. Countries with a low fertility rate (and low crude birth rate of 10 to 12 in 2016) include European nations, the United States, and China. Death Trends The crude death rate measures the rate of deaths for every 1,000 people in a given population. Crude death rates of below 10 are considered low, while crude death rates above 20 per 1,000 are considered high. Crude death rates in 2016 ranged from 2 in Qatar, the United Arab Emirates, and Bahrain  to 15 per 1,000 in Latvia, Ukraine, and Bulgaria.   The global crude death rate in 2016 was 7.6, and in the United  States,  the rate was 8  per 1,000.  The  crude death rate for the world has been on the decline since 1960 when it came in at 17.7. It has been falling around the world (and dramatically in developing economies) due to longer life spans  brought about by a better food supplies and distribution, better nutrition, better and more widely available medical care (and the development of technologies such as immunizations and antibiotics), improvements in sanitation and hygiene, and clean water supplies.  Much of the increase in world population over the last century overall has been attributed more to longer life expectancies rather than an increase in births.

Finally, the assignment is concluded with the thought that solar energy is a renewable resource which when used causes no pollution and for this reason, the world is watching that solar energy is not only capable of saving electricity but also it has many offerings that goes beyond what most people think. Solar Energy: An infinite resource meeting our infinite demand Introduction Sun had been the main source of energy since the Earth was born. It is the source for primary production. People have been using the energy of Sun in various ways. Apart from these usages, people have finally learnt to generate Solar Power from the solar energy. The Sun is 150 kilometers away, and amazingly powerful. Just the tiny fraction of the Sun’s energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet our power needs many times over. In fact, every minute, enough energy arrives at the Earth’s surface to meet our demands for a whole year – it the energy could be harnessed properly. That is, Solar Energy is an infinite resource meeting our infinite demand. The sun produces a tremendous amount of energy. Every second, more than  4 million metric tons  of hydrogen is converted into helium. But even at this rate, the sun will continue producing solar energy for another  5 billion years. As a result, solar energy is considered the ultimate  renewable energy. Aspect to be covered: The use of solar energy to generate solar power (solar cells) and save electricity. Motivation: Nowadays, non-renewable resources are at crisis. In Bangladesh, electricity consumption is high and it fails to meet the demand. Bangladesh suffers load shedding at a high rate. Therefore, in order to save electricity, people must come forward and learn to harness solar energy in order to produce solar power. The more efficiently the solar energy can be harnessed, the more electricity can be saved. Using solar energy we will be able to reduce our carbon footprint and be free from rising utility rates. Importance of Solar Energy Generating Solar Power involves no pollution. Environmentally, it is the most Clean and Green energy. Solar energy is clean, renewable (unlike gas, oil, and coal), and sustainable, helping to protect our environment. Solar Energy Is Important In Nature: Solar energy is an important part of almost every life process, if not, all life processes. Plants and animals, alike, use solar energy to produce important nutrients in their cells. Plants use the energy to produce the green chlorophyll that they need to survive, while humans use the sun rays to produce vitamin D in their bodies. However, when man learned to actually convert solar energy into usable energy, it became even more important. Solar Energy Is Important As Clean Energy: Since solar energy is completely natural, it is considered a clean energy source. It does not disrupt the environment or create a threat to Eco-systems the way oil and some other energy sources might. It does not cause greenhouse gases, air or water pollution. The small amount of impact it does have on the environment is usually from the chemicals and solvents that are used during the manufacture of the photovoltaic cells that are needed to convert the sun’s energy into electricity. This is a small problem compared to the huge impact that one oil spill can have on the environment. The Conversion of Solar Energy to Solar Power Solar Cells (also called â€Å"Photovoltaic†, â€Å"PV†, or â€Å"Photoelectric† cells) convert sunlight into electricity. It is made up of three subsystems * The PV Devices generate the solar power by converting sunlight into direct-current (DC) electricity. * The BOS consists of all the equipment between the PV devices and the load. It includes the structure for mounting the PV devices, he power conditioning equipment to convert the DC electricity to alternating current (AC) for the use by the load, and batteries for storing the PV generated electricity if desired. The Load is simply the device that uses the electricity. The television is a good example of a load. Case Studies: * Germany has long been the world leader in producing solar electricity Some people believe that Germany’s walk away from nuclear power will lead it  down to more fossil fuel plants own  and all the CO2 emissions that come with them. But the country was cranking solar electric ity like it or no nation ever has, according to the International Economic Platform for Renewable Energies in Muenster. The group said in a press release last Saturday that photovoltaic operations in Germany were producing at 22 gigawatts for a cloudless stretch beginning at around noon on Friday, May 25, 2012. As the institute pointed out, that was the equivalent of about 20 nuclear power plants. You read "Solar Power" in category "Papers" Germany has long been the world leader in producing solar electricity, in large measure because over a decade ago it implemented â€Å"feed in tariffs† (FiTs) that essentially pay people and businesses for generating solar. Germany has been cutting those tariffs steadily, and at an accelerating pace as plunging prices of solar panels makes them less necessary. The FiTs have encouraged solar uptake and have led to lower prices through manufacturing economies of scale. On top of that, Chinese manufacturers have pushed prices down. German’s Parliament recently sped up FiT cuts in part because the subsidy has led to higher electricity prices,  a Bloomberg Businessweek story noted two months ago. The importance of solar is now greater than ever in Germany, following the country’s decision to abandon nuclear power after Japan’s Fukushima nuclear meltdown in March 2011. The world is watching this one. * Exploration of Solar Power In Bangladesh Bangladesh is a massively power-deficient country with peak power shortages of around 25%. More than 60% of its people do not have access to the power grid. The country only produces  3500-4200  MW of electricity against a daily demand for 4000-5200 MW on average, according to official estimates. Solar energy is an ideal solution as it can provide grid less power and is totally clean in terms of pollution and health hazards. Since it saves money on constructing electricity transmission lines, it’s economical as well. Little wonder that  it is becoming popular in Bangladesh. The number of households using solar panels has now crossed the one million mark, the fastest expansion of solar use anywhere in the world. In 2002, just 7,000 households in Bangladesh were using solar panels, but now more than one million households, or five million people, are benefitting from solar energy. The Government of Bangladesh has also withdrawn all the import tariff and VAT (Value Added Tax) on the raw materials of solar panels for the current fiscal year. In his budget speech, the Finance Minister Abul Mal Abdul Muhit said that Bangladesh gets about 250 to 300 sunny days on average per year (rainy days are not included). He added that since the maintenance cost is very low, we could massively increase the use of solar power in the country. The solar panel providers in Bangladesh are now expecting the price of batteries and accessories to drastically reduce. In fact, solar panels and accessories imported from countries in the developed world like Germany cost a lot, but the same panels manufactured in China cost much less. In the capital city, Dhaka, the power department has set a pre-condition of installing solar panels on buildings applying for new connections. In the villages, solar power is even being used to operate pumps for irrigation. Today both urban city dwellers and villagers in remote areas of Bangladesh are using solar energy.

The company has already set up a manufacturing plant at Gazipur at a cost of Tk. 27. 27 crore in effort to reduce country’s dependence on import of Solar Panel. In addition, BANECO has a plan to manufacture solar power station in each district, solar irrigation pump and solar streetlight gradually. * Powering Streetlights in Dhaka with Solar Power Currently, Dhaka uses around 22,000 sodium lights and 57,000 fluorescent lights for its streetlights. Plans are afoot to have solar-powered lights at 100 traffic intersections under a separate project funded by the World Bank. The solar panels will also power automatic time-countdown displays at intersections to tell motorists when the next change of lights will be. The power demands of traffic lights are insignificant, but officials said the project will raise awareness among the motorists about green technology. * Planning 1000 MW Solar Power Plant in Gujarat, India Taking cue from Gujarat, Damodar Valley Corporation (DVC) proposes to set up solar power plant atop 2,494 kilometers long network of canals that has the potential to generate up to 1,000 mw green solar power. Setting up solar power plant atop water canal eliminates the need for land acquisition and water evaporation from the canal that is quite high in India with sunshine for nearly 300 days in a year. Future of Solar Power: The future of solar PV looks rather bright. The industry has consistently been able to lower the cost of solar panels. If this trend can be maintained for the next 10 years, and if subsidies are continued for that period, there is a real prospect for solar to become cost competitive on its own (that is, without a subsidy), at least for commercial installations. Utility-scale installations will take longer to become competitive. Conclusion Solar energy is lauded as an inexhaustible fuel source that is pollution and often noise free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars. Today’s solar product offerings go way beyond what most people think of when they hear the term ‘solar power’ or ‘solar energy’ – typically they imagine solar electric panels on a roof converting sunlight into electricity. While these ‘photo voltaic’ panels do represent a piece of the solar pie, many more solar-powered products and technologies utilizing the sun’s energy now exist. Solar PV systems, battery-backed off-grid systems, solar farms and more are at the forefront of the solar power world innovations, with more to come.

Maloney says that Southern California is pushing for solar power in the desert cause the amount of sunlight with virtually no clouds, â€Å"but its also the home to the Mojave ground squirrel, the desert tortoise and the burrowing owl, and to human residents†. Maloney also states that the US Bureau of Land Management says that it had applications submitted for solar power that would cover 78,490 acres in the desert. We will write a custom essay sample on Solar Power or any similar topic only for you Order Now For the entire US, the number of applications grew from zero two years ago to more than 125 with enouch potential electrical power of 70,000 megawatts or the equivalent to 70 large coal plants. The rush to try and get this land is caused by a California Law that calls for 20 percent of the state’s electricity must come from renewable resources by 2010. Jim Harvey, who is the founder of the Alliance for Responsible Energy Policy, is quoted by Maloney saying, † Our position is that none of this is needed. We support renewable energy, and we support California’s renewable energy targets, but we think it can be done through rooftop solar†. Harvey also pointed out the success that Germany was having by using rooftop solar panels. The way it works is that the government offers payments for electricity generated from solar panels. The payment is roughly 50 cents per kilowatt hour. The average payment in the US in 11 cents per kilowatt hour, but the payments would not be as high as the German payments here. Maloney goes on to say not only would the solar panels destroy habitats, it would run the deserts small water supply, as it is, even more scarce. The mirror and solar panels would have to be washed, and some panels use turbines which would require more water. Terry Frewin, chairman of the Sierra Club’s California/Nevada desert commitee, says that † solar panels destroy all natice resources on site, and have indirect and irreversible impacts on surrounding wilderness†. At the current rate of adding 200 megawatts of rooftop solar panels a year, it would take â€Å"100 years to meet the 20 percent renewable [target set] by California†. The first major debate over a large solar power project was over the 250 acres of land, which was on the outskirts of Victorville, California, on the western side of the Mojave that was gonna be used for the solar panels. Inland hired people to look for the endangered ground squirrel and desert tortoise. No squirrels were found but some tortoises were, so the Inland, cmpany building the panels, said for every acre of lost habitat they would buy one acre of land to offset it. Although it would cost some â€Å"6.5 million to 10 million dollars† to buy the offsetting acreage. How to cite Solar Power, Essay examples

The company has already set up a manufacturing plant at Gazipur at a cost of Tk. 27. 27 crore in effort to reduce country’s dependence on import of Solar Panel. In addition, BANECO has a plan to manufacture solar power station in each district, solar irrigation pump and solar streetlight gradually. * Powering Streetlights in Dhaka with Solar Power Currently, Dhaka uses around 22,000 sodium lights and 57,000 fluorescent lights for its streetlights. Plans are afoot to have solar-powered lights at 100 traffic intersections under a separate project funded by the World Bank. The solar panels will also power automatic time-countdown displays at intersections to tell motorists when the next change of lights will be. The power demands of traffic lights are insignificant, but officials said the project will raise awareness among the motorists about green technology. * Planning 1000 MW Solar Power Plant in Gujarat, India Taking cue from Gujarat, Damodar Valley Corporation (DVC) proposes to set up solar power plant atop 2,494 kilometers long network of canals that has the potential to generate up to 1,000 mw green solar power. Setting up solar power plant atop water canal eliminates the need for land acquisition and water evaporation from the canal that is quite high in India with sunshine for nearly 300 days in a year. Future of Solar Power: The future of solar PV looks rather bright. The industry has consistently been able to lower the cost of solar panels. If this trend can be maintained for the next 10 years, and if subsidies are continued for that period, there is a real prospect for solar to become cost competitive on its own (that is, without a subsidy), at least for commercial installations. Utility-scale installations will take longer to become competitive. Conclusion Solar energy is lauded as an inexhaustible fuel source that is pollution and often noise free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars. Today’s solar product offerings go way beyond what most people think of when they hear the term ‘solar power’ or ‘solar energy’ – typically they imagine solar electric panels on a roof converting sunlight into electricity. While these ‘photo voltaic’ panels do represent a piece of the solar pie, many more solar-powered products and technologies utilizing the sun’s energy now exist. Solar PV systems, battery-backed off-grid systems, solar farms and more are at the forefront of the solar power world innovations, with more to come.

Maloney says that Southern California is pushing for solar power in the desert cause the amount of sunlight with virtually no clouds, â€Å"but its also the home to the Mojave ground squirrel, the desert tortoise and the burrowing owl, and to human residents†. Maloney also states that the US Bureau of Land Management says that it had applications submitted for solar power that would cover 78,490 acres in the desert. We will write a custom essay sample on Solar Power or any similar topic only for you Order Now For the entire US, the number of applications grew from zero two years ago to more than 125 with enouch potential electrical power of 70,000 megawatts or the equivalent to 70 large coal plants. The rush to try and get this land is caused by a California Law that calls for 20 percent of the state’s electricity must come from renewable resources by 2010. Jim Harvey, who is the founder of the Alliance for Responsible Energy Policy, is quoted by Maloney saying, † Our position is that none of this is needed. We support renewable energy, and we support California’s renewable energy targets, but we think it can be done through rooftop solar†. Harvey also pointed out the success that Germany was having by using rooftop solar panels. The way it works is that the government offers payments for electricity generated from solar panels. The payment is roughly 50 cents per kilowatt hour. The average payment in the US in 11 cents per kilowatt hour, but the payments would not be as high as the German payments here. Maloney goes on to say not only would the solar panels destroy habitats, it would run the deserts small water supply, as it is, even more scarce. The mirror and solar panels would have to be washed, and some panels use turbines which would require more water. Terry Frewin, chairman of the Sierra Club’s California/Nevada desert commitee, says that † solar panels destroy all natice resources on site, and have indirect and irreversible impacts on surrounding wilderness†. At the current rate of adding 200 megawatts of rooftop solar panels a year, it would take â€Å"100 years to meet the 20 percent renewable [target set] by California†. The first major debate over a large solar power project was over the 250 acres of land, which was on the outskirts of Victorville, California, on the western side of the Mojave that was gonna be used for the solar panels. Inland hired people to look for the endangered ground squirrel and desert tortoise. No squirrels were found but some tortoises were, so the Inland, cmpany building the panels, said for every acre of lost habitat they would buy one acre of land to offset it. Although it would cost some â€Å"6.5 million to 10 million dollars† to buy the offsetting acreage. How to cite Solar Power, Essay examples

Realism In Death Of A Salesman Essay Paper Example For Students

Realism In Death Of A Salesman Essay Paper RealismRealism is defined as an attempt to reproduce faithfully the surface appearance of life. Death of a Salesman can be termed as a realistic play in many ways. The play has characteristics of an everyday-life situation. Death of a Salesman is almost equivalent to some families, in the way of Willy and Biffs disagreement on certain ideas. Willy is upset with Biff because he has not settled down and found a good job. As Happy and Biff are in the bed talking, Biff tells Happy, I tell ya, Hap, I dont know what the future is. I dont knowwhat Im supposed to want.(Miller 1642) Biff is unsure of his future. Willy, as he is talking to Linda, says, How can he find himself on a farm? Is that a life? A farmhand? In the beginning, when he was young, I thought, well, a young man, its good for him to tramp around, take a lot of different jobs. But its more than ten years now and he has yet to make thirty-five dollars a week!(1639) Willy is upset because he wants Biff to have a more productive life and to be very successful. I may not be as old as Biff is in the play, but I am in college and still trying to figure out my future. My parents are questioning me about my future but I am trying to be patient and decide on a great career. My situation is like Biffs, except my parents are not mad at me for not deciding quickly. Willy has some mental problems, as many people do, that cause him to do out of the ordinary things. One of his mental problems is that he talks to himself. Willy is sitting in the kitchen by himself and starts talking to Biff as if he were in high school, Just wanna be careful with those girls, Biff. Dont make any promises. No promises of any kind. Because a girl, yknow, they always believe what you tell em, and youre very young, Biff, youre too young to be talking seriously to girls.(1646) I have known people who are getting old start to talk to a stranger as if that person were their own daughter or son. This is not an exact example of Willys problem but it is close. Many elderly people suffer from mental problems. I would say it is just a reality of growing old. After Willys funeral is over, Biff and Happy are talking to one another about their father. Biff tells Happy that Willy did not know who he was. Happy is infuriated at Biff for his comment. Biff says, I know who I am, kid.(1706) Happy then says, All right boy. Im gonna show you and everybody else that Willy Loman did not die in vain. He had a good dream. Its the only dream you can ever haveto come out number-one man. He fought it out here, and this is where Im gonna win it for him.(1706) After Happy says that, Biff gives Happy a hopeless glance because Biff knows he is going to turn out to be just like Willy, thinking that having money, being well-liked, living lavishly, and having power is the most important things in life.In someway it is the same as abused children. After their parents have gone or the kids have grown up and moved out, they are most likely going to be the same way to their children as their parents were to them. Happy is going to end up being a salesman who has th e wrong perspective on the meaning of success. Death of a Salesman is very much like some families or people in real life. Author Miller did an excellent job of making this play realistic. Throughout my life, I have seen many families go through this same situation. Miller accomplished the attempt to make Death of a Salesman as real as life itself. .uad5fa7d273a092c8a9a7c735bd18b514 , .uad5fa7d273a092c8a9a7c735bd18b514 .postImageUrl , .uad5fa7d273a092c8a9a7c735bd18b514 .centered-text-area { min-height: 80px; position: relative; } .uad5fa7d273a092c8a9a7c735bd18b514 , .uad5fa7d273a092c8a9a7c735bd18b514:hover , .uad5fa7d273a092c8a9a7c735bd18b514:visited , .uad5fa7d273a092c8a9a7c735bd18b514:active { border:0!important; } .uad5fa7d273a092c8a9a7c735bd18b514 .clearfix:after { content: ""; display: table; clear: both; } .uad5fa7d273a092c8a9a7c735bd18b514 { 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; } .uad5fa7d273a092c8a9a7c735bd18b514:active , .uad5fa7d273a092c8a9a7c735bd18b514:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uad5fa7d273a092c8a9a7c735bd18b514 .centered-text-area { width: 100%; position: relative ; } .uad5fa7d273a092c8a9a7c735bd18b514 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uad5fa7d273a092c8a9a7c735bd18b514 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uad5fa7d273a092c8a9a7c735bd18b514 .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; } .uad5fa7d273a092c8a9a7c735bd18b514:hover .ctaButton { background-color: #34495E!important; } .uad5fa7d273a092c8a9a7c735bd18b514 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uad5fa7d273a092c8a9a7c735bd18b514 .uad5fa7d273a092c8a9a7c735bd18b514-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uad5fa7d273a092c8a9a7c735bd18b514:after { content: ""; display: block; clear: both; } READ: HIV: The Search For A Vaccine EssayReferencesMiller, Author.
