Posters of the Second World War An Analysis
Posters of the Second World War An Analysis What was the impact of the posters from the Second World War?Why are they still popular? Introduction: For my dissertation I have chosen to look at the posters from the Second World War. The idea to look at these posters came from my own interest in the war, the 1940s and the propaganda posters. I wanted to look further into them; why they were created, and what for?, did the posters do anything to help people during the war? And how/ why they still remain so popular today? After researching the era, researching the posters and visiting various places I decided I wanted to look at how people acted upon these posters and how they all helped with the war effort. Life changed massively from the moment it was announced Britain was at war Everything was rationed from food to petrol, gas masks were issued, children had the option to be evacuated, men were going to war and women were working. Even though there was so much going on and your normal day to day life could change at any moment the government wanted to try and get people to work and live as normally as they possibly could. The government was issuing hundreds of posters; urging people to work for victory, reminding you to wear your gas masks, talk less, turn off the lights, walk to work, plant vegetable, health posters and so many more. I wanted to look into these posters and how they helped people throughout the war and if they did help at all. There was so many posters produced, some of the posters I wanted to look at are: Keep Calm and Carry on, Dig for Victory, Make do and mend, Dont do it, mother leave the children where they are and a few more. One of the many things of the war I have always found interesting and is something I wanted to look at within this dissertation is family life Evacuation and the make do and mend. Evacuation of the war was one of the greatest movement and decisions made by the government during the war over 3,500,000 children were taken away from their homes to avoid the bombings and move out to the country and smaller areas less likely to be attacked. The first big attack on London lasted up to 76 days and nights, thousands were killed, injured and made homeless: The homeless resulted to camping nearby and thousands of people slept on the platforms of the underground stations each night. The main places were evacuation was taking place were on large cities such as London, Manchester, Liverpool, Portsmouth, Southampton, Bristol and Glasgow. Even though evacuation was an optional thing to do the government tried to push it as much as possible so children were safe and out of the way. After a while n othing was happening and parents felt that their children had been sent away for no reason, the government produced hundred more posters to try and explain that this wasnt the case. I wanted to look more into these posters to find out when these posters started to go out to the public, what the reaction was and if they did work like they hoped. Chapter One: The Second World War Why were these posters produced? Did they do anything? Chapter Two: Keep Calm and Carry On Why has this poster become so iconic? Chapter Three: Imitations and Popularity Why are these posters still so popular? How have they been reused? Chapter One:The Second World War Why were the posters produced? Did they do anything? Before the war officially broke out the government tried everything to prepare Britain for what was to come. Posters were one of the main ways to get the message across to the general public, which means these posters would have been seen everywhere. So many posters were produced during the second world war informing the general public on everything; Appeals and instructions, Immunization against Diphtheria, preventing the spread of a common cold, women covering their hair in factories, Dig for Victory and so many more. The earliest poster produced by the Ministry of Information was your courage, Your Cheerfulness, Your resolution will bring us victory which was one of three in a series of posters produced in 1939. Evacuation:Evacuation began on 1st September 1939 inn major cities such as London, Manchester, Belfast and Liverpool. The government wanted the children out of the way before the attacks started, it was expected that the war would open with a massive aerial attack on British cities. The government designed came up with the idea to protect people in Britain but particularly children by moving them to areas thought to be less at risk. School children (827,000) and their teachers, Mothers with children under 5 (524,000), Pregnant women (12,000) were evacuated. There were many posters produced by the government for the idea of evacuation; Mothers send them out of London -even though evacuation was voluntary the government tried to urge women to register their children for evacuation to protect them from what was to come and they would be safer from the bombs in the country. Evacuees returned home January 1940; The period known as the Phoney War, no real danger was happening and a lot of people felt cheated that they had sent their children away for no visible reason. Efforts were made to persuade parents that it was their patriotic duty to send their children back to the country. With children returning home the Ministry of Health produced more posters warning mothers not to be tempted by Hitler and the non- events that have happened; DONT do it mother LEAVE THE CHILDREN WHERE THEY ARE. Many of the posters produced at this time for evacuation were talking to the mothers trying to persuade them to leave the children where they are where they are the safest. This particular poster is one of the most recognised; it portrays a mother and her two children with a ghostly figure of Hitler saying take them back! Take them back! Take them back!. The design of the poster is very simple with a hand drawn black and white image with the text being the main focus h ighlighted in red. The one downside to the evacuation at first was not everyone was keen to take the children in but for some they did go and live with family or family friends. It might be you! Caring for evacuees is a national service These posters were produced to remind people of their duty to help with the war efforts by taking in the homeless from the cities. Dig for VictoryRationing began 8th January 1940 just months after the Second World War broke out. The Dig for Victory campaign was set up during the Second World War by the Ministry of Agriculture; the idea was to encourage men and women to grow their own food to help with the war effort. Many open spaces were turned into allotments; a garden, public parks even the lawn outside the tower of London was turned into a vegetable patch. Before rationing and the Dig for Victory campaign was introduced Britain was reliant on the cheap imports of food from overseas; main suppliers were from Canada and America. Everyone had to help with the effort: Men, women and children everyone could do their bit whether it was looking after an allotment or growing vegetables in the garden or window box. The Dig for Victory campaign seemed to be successful with getting the help with the war effort message across. It became a part of childrens everyday school routine all children helped digging by going to the parks in the afternoon to dig up carrots, cabbages and potatoes. By 1943 there were over 1.4million allotments producing over a million tons of vegetables that year. Two very iconic posters are Your own vegetables all the year round if you dig for victory now and Dig for Victory they both have two very different designs with the same messages. Out of the both of these posters the most iconic and recognisable is the poster of the young boy with his back to you while his walks off to contribute to the war effort. This has such a basic design and colour pallet but with a clear Dig for Victory message. The other however is similar to the evacuation poster, the main focus of the poster is not meant to be the imagery but it is the text. This has been highlighted in yellow and black along with a large font to grab your attention. There were many posters produced for the Dig for Victory campaign and others by the Ministry of Health. The Ministry created cartoon characters such as Potato Pete and Doctor Carrot, the idea was to show how good these vegetables were for you. Slogans read: Im a protective food- says Potato Pete, Call me often and youll keep well Doctor Carrot. These adverts/ posters proved successful and were popular amongst children as they both had songs to go alongside them as well as recipe books for the parents. Dig for Victory, grow your own vegetables now, your own vegetables all the year roundif you DIG FOR VICTORY NOW! a lot of posters produced showed more women working than they did men at this time; As a lot of the men went to war it was the womens job to fill in and do the jobs the men had left behind. Rather than showing young women in elegant dresses, magazines and posters showed happy young women with pitch forks helping the war effort. Without these posters persuading and showing the women doing mens jobs (factory, farming, Mechanics) the jobs for women wouldnt have progressed like they have done and they would still be expected to be housewives. The Dig for Victory campaign proved to be one of the most successful from the Second World War. The idea of growing your own food didnt just stop straight after the war had ended, it continued for many years after and people are still doing it now. Both of these posters proved to be a huge success during the Second World War, the general public acted upon them and chose to do the right thing to help with the war effort. The posters changed the way the UK lived and worked for many years after and they still have an effect on what we do today. Chapter Two: Keep Calm and Carry On -Why has this poster become so iconic? The message Keep Calm and Carry on nowadays has been completely taken out of context and is seen everywhere; posters advertising events (pub quiz), used online (Memes Keep calm and go to Hogwarts), Companies are using the slogan and has appeared on Homeware and so much more. But why do people still love this message?The poster was originally produced by the Ministry of Information in 1939 after the outbreak of the Second World War. The Ministry of Information designed three morale boosting posters which were to be displayed across Britain. They read; Your Courage, Your Cheerfulness, Your Resolution will Bring us Victory, Freedom is in Peril, Defend it with all your might and Keep Calm and Carry On. Two out of the three posters were seen on public transport, in shop windows, on notice boards and many other places across Britain. The Ministry of Information produced hundreds of posters during the war to spread important messages. During the war the main way of reaching people was thro ugh billboards, public transport and in papers during the 1940s people werent trying to compete with television, internet and social media. The Keep Calm and Carry on poster was rediscovered in 2000 at Barter Books in Alnwick, Northumberland. The owner of the shop found the poster folded up at the bottom of a box of books. After the poster was found it was framed and hung in the shop It attracted so much interest that the owners began to produce and sell copies. Later this turned into more products and then soon after other people copied the keep calm and products with this slogan were seen everywhere. The plan for the Keep Calm poster was to only issue it on the invasion of Germany This didnt happen which meant the poster was never officially seen by the public. Over two-and-a-half-million copies were printed to be distributed across Britain. The Keep Calm poster is one of the many few during the war that wasnt telling people to go out and fight, dig for victory, made do and mend as well as careless talk. This particular poster was just a simple message telling people to remain calm during the situation and not to panic. The poster is now seen not only as a distillation of a crucial moment in Britishness, but also as an inspiring message from the past to the presentin a time of crisis Susannah Walker-Design Historian I agree with the previous statement, people admire many posters from the second world war for many reasons; some of the posters are still relatable, bring back memories and have stories to tell. However Keep Calm and Carry On it is one of the most well-known posters from the war which was never used. People nowadays still like this poster as it is a nostalgic memory from the war but when the series of posters were released people didnt like them; the people who saw the posters said they were patronising and divisive. The entire campaign produced by the Ministry of Information was completely scrapped just after four weeks. The posters they had printed were stored away and kept until April 1940, The majority of the posters were pulped as part of the governments idea to recycle paper so only a few copies survived. With its rising popularity over the years it has become one of the iconic images of the 21st century, not just from the original design but from everything that has come from this one image. The popularity of the poster spreads further than just Britain; it has been spotted in seaside town gift shops in America. When it reaches places like this the poster ends up losing its Britishness and becomes a very stereotypical thing about the country. Why is it hated? People like the original postern for how British it is as well as it having a sense of nostalgia and memories of the war as well as the message behind the poster; it is also hated by what has become of it and how it is constantly adapted online. Online was the first place where the poster began to go away from the original message; Keep Calm and Call Batman, Keep Calm and Hakuna Matata, Keep Calm and Eat a cupcake and so many more. Soon after the adapted versions were seen on mugs, notebooks, being used to advertise products People wanted to see the end of the poster after this. But why do we as a country still love and cling onto this poster?Realistically with the Keep calm and carry on poster people want to hate it (some do) and wish it would die of death like many other trends over the years, many people however secretly do like it.In the UK we are drawn instantly to anything baring the flag, Royal Family, Tea and all the normal stereotypical British things. It is the same with this poster; people are drawn to the Britishness of it and the calming yet nostalgic message. It is one of the many posters from the Second World War that at times can still relate to any issue going on in our country. It still spreads the same message to us now as it should have done then. Comparing the current government to the government then it would be difficult for them now to come up with a poster that has the same appeal to it powerful and simplicity might not be enough these days. Posters produced by the government now attempt to convince the public of a danger and get them to modify their behaviour; Keep Calm and Carry On tells you to think another way and continue acting as you have always acted. There would be attempts to create new and improved posters or even try and develop ones that already exist. If anything were ever happen to the United Kingdom like it did during the war, people would go back and dig out the old posters. They worked before, they will work again. Chapter Three:Imitations and Popularity Why are these posters still so popular? How have they been re-used? Many of the posters from the Second World War are always being imitated; if its to advertise new products of to promote a local event. These posters are always coming back around just designed in a different way; one of the easiest posters to re-produce is Keep Calm and Carry On. Keep Calm and Carry OnIn 2012 McFly promoted their tour called The Keep Calm and Play Louder tour the design of the poster was kept the same with the red background and the grown of King George but with the bands logo added to the image. Another company to use the Keep Calm was Nectar in 2010 to promote the loyalty card; Keep Calm and Carry One. The campaign was featured in over nine newspapers including; The Sun, Daily Mirror, Metro, The Times and The Telegraph. The design of the poster was kept similar to the original with the layout and text The background was the Nectar purple and in place of the crown was the nectar card. In 2012, Shepheard Neame released limited edition bottles; Keep Calm and Celebrate. The idea behind the bottle was to evoke on the country-wide pride during the summer of national celebration; London Olympics, Diamond Jubilee and Euro 2012 as well as to commemorate the Battle of Britain The bottles were only issued at large events. The design of the Keep Cal m was kept simple background changed to navy and in place of the crown was a spitfire. Ministry of FoodIt isnt just the posters that are always being imitated and reproduced, its even sayings and old campaigns. Back in 2008, Jamie Oliver released a book and TV series called Ministry of Food This has been taken from the food rationing system from the war.What was the Ministry of Food during world war two?During the Second World War the Ministry of food was more known as Minister of food and Minister of food control. The main task for the Minister of Food during the war was to oversee the rationing in the UK; originally the idea of rationing began as an experiment and for the ministry it worked surprisingly well. Rationing officially began in early January 1940 and was a major success of the Second World War. With the food supplies cut short because of Germanys actions and the needs of the services, rationing was an essential and by 1942 most foods were rationed. One issue the Minister of food had with the rationing was children they wanted to make sure that Britain wa s providing 650,000 children with free school meals and to guarantee them an adequate nutrition (for everyone not just the children). The minister of food released recipes to help people through the war to create simple and easy meals with the little food they had. Jamie Oliver TV program and book idea was an aim to try and recreate the success of the ministry of food and try and encourage healthy eating. From this program he set up four Ministry of food centres which were all offering the food he had been producing on the show. The title of the show is a play on the Ministry of food and Minister of food. Make do and mend Make do and mend isnt a poster that people are taking off but it is still something a lot of people do still follow. You could argue that we now live in a throw-away society when our clothes get stained or the seams of trousers show any wear we simply dispose of the item or rebuy them as clothing has become cheaper. There are however a lot of younger people who prefer to upcycle clothes or even make their own from rummaging through a charity shop. The Make do and mend campaign started when clothes rationing was introduced during the Second World War. The Ministry of information produced a pamphlet encouraging people to do whatever they could to extend the life of their clothes (a leaflet which is still reproduced and sold in some museum gift shops). The campaign played an important part in the daily life during world war two. The shortage of clothes was down to sinking ships coming into England as well as the clothing manufacturers were commissioned to manufacture uniforms as a priority. As clothing was now a shortage, in 1941 clothes rationing was introduced: people were given 66 coupons a year (which was later reduced) a womans blouse was 12 coupons, 11 coupons for a dress, 2 for socks/stockings, 8 for a mens shirt or trousers, 5 for womens shoes and 7 for men and extra coupons were given to children. As everything was being rationed clothes had to last a lot longer so people began to make new clothes from the old and from a ny other household linen. Nothing was thrown away, especially if it could be made into something else. A pamphlet was part of the campaign and was intended to provide housewives with useful tips and ideas on how to reuse old clothing. Readers were advised to create: decorative patches to cover holes on warn garments, unpick old jumpers to re-knit alternatives and turn mens clothing into womens. One of the hardest things for parents with the clothing ration was struggling to clothe their growing children Clothing Exchanges were set up by the womens voluntary service to help meet these parents needs. Parents could take clothes their children had outgrown and swap it for new clothes. Like I mentioned previously a lot of people do enjoy Sewing, knitting, crochet and making their own clothes and it is still a popular thing to do. I think that the make do a mend campaign is still applies now and people do still follow the ideas and information inside the pamphlet like people did then. Within this dissertation the one poster I wanted to look at more so than the others was Keep Calm and Carry On. It is the most overused poster from the 1940s and has slowly become one people cant stand. The meaning behind the poster has been lost and taken out of context, from the way it is used online through memes to the way companies are using it to advertise products. I have discovered that a lot of the hate towards the poster has come from online and how it became adapted and stepped away from the original message; Keep calm and go to Hogwarts, Keep calm and call the doctor, Keep calm and let it go and so many more. The adapted versions are seen everywhere. In conclusion to this I have found out that the posters from the Second World War will always have a strong impact on Britain There was throughout the war and they have had a similar impact for many years after. These posters will always remain popular; we are drawn to them regardless if it is the original posters or somethi ng that has been created from the original. Posters such as Dig for victory is still a poster that is followed today with people still growing their own vegetables, Make do and mend is another poster which is still followed with people still making their own garments from scraps and new fabrics.

History And Importance Of Hydropower
History And Importance Of Hydropower Hydropower is produced by converting the kinetic energy of the moving water to electrical one. The motion of water is part of a continuous natural phenomena called the water cycle. Energy from the sun evaporates water from oceans and rivers and raise it as steam or vapor. When the watervapor reaches a colder atmosphere level, it condenses and forms cloud. The moisture eventually reaches a point at which air cannot keep carrying it, so it falls to the earth as rain or snow, this process is called precipitation. Gravity drives the water, moving it from higher ground level to lower one. The force of moving water can be extremely powerful. Hydropower is a renewable energy source because the water on the earth is in a continuous motion. As long as the water cycle continues, we will not run out of this source. In the old past people used a simple machine called water wheel to produce a specific motion using the movement of the water in the rivers or any other source. The water wheel is located below a source of flowing water. It captures the water in plates that is normal to the wheel, the water hits the plates causes the wheel to turn. Water wheels convert the kinetic energy of the water into another type of motion. That energy can then be used to grind grain, drive sawmills, or pump water. There are several examples of water wheel application in the past. For instance, the Greeks used water wheels to grind wheat into flour more than 2,000 years ago. In the beginning of the 18th century, factories at America and Europe used it also to power machines. In the late 19th century, the potential energy of water was used to generate electricity. The first hydro electric power plant was built at Niagara Falls in 1879 and it started a revolution of Hydro electrical power plants. in the following decades, many plants were built. At the peak in the early 1940s, hydropower occupies 33 percent of USA electricity. But, by the end of 1940s, inexpensive fossil fuel plants also joined the competition. At that time, plants burning coal or oil could make cheaper electrical power than hydro power plants. This fossil fuel plants was burning the fossil fuel and the hydro power plants till the 1970s. In that decade the way was opened for hydro power plants again because of the oil shocks that made people showed an interest in renewable power sources. 1.3 Importance In this part of the report, I am going to relate people and hydropower in a logical chain, that will show how much it is important to change the way that electricity is produced nowadays. People, as we all know, are part of the natural world and the materials they are using in building, clothing, food, etc come from natural resources. What surround us are composed of large numbers of built environment, the facilities built by humans for comfort, security, and well-being. As our built environment grows, we become more reliant on what it is offering to us. To satisfy our demands improvement to our built environment is needed, to do such upgrading we need electricity which can be generated by using the resources of natural fuels. In obtaining these resources, it is necessary to drill oil wells, tap natural gas supplies, or mine coal and uranium. In order to put water to work on a large scale, storage dams are needed. Some human activities have more lasting impacts than others. Techniques to mine resources from below the earth may leave long-lasting impacts on the environment. Oil wells may detract from the beauty of open landscapes. Reservoirs behind dams may cover whole valleys. The usage of energy sources can further impact the land, water, and air in different amounts. People want clean air and water and a pleasing environment. They also want power to heat and light the homes and to run machines. So, what would be the solution? Logically there are two straight forward solutions, but both are hard to be done. One solution is curbing The increasing demand for electrical power. As explained above, this is something that far from the actual trend. The other solution is that more power must be produced in environmentally friendly ways. Conservation can save electricity, but our population is growing. In other words even if we are very conservative in power consumption, our demand is still increasing. So, growth is inevitable. So again, the wisest solution is a careful, planned approach to how to bring a new, efficient ,clean and renewable resource of energy. All choices must be examined, and the most efficient, acceptable methods should be adopted. One alternative is hydro power plants and based on the characteristics of this plants it seems to be a successful choice. These features are many, one is that hydro power plants do not use nonrenewable resources to make electricity. They also do not produce pollution, rarely fail, have low operating costs and they are reliable. WAYS OF HYDROPOWER PRODUCTION I will discuss in this part of the report two methods to produce power using hydro energy that fit with the conditions in Saudi Arabia which are the lack of dams and rivers. These two ways are the sea power plants and power production in water Desalination stations. Using Sea Energy First of all I will discuss tidal energy as one type of the sea energy. The tides rise and fall eternally . Tides are changes in the level of the oceans caused by the rotation of earth and the gravitational force from both the moon and the sun. Nearshore sea level can vary up to 15 meters, depending on different factors. Tidal energy is the most promising source of ocean energy for today and the near future. Tidal energy plants capture the energy in the same manner that happened in dams, but here the dam is the whole coastal line. The water is filling this virtual dam and draining it twice a day. Then, by sitting up a set of turbines that connected to gears to convert the motion of the water into electrical power, and by building specific structures under the sea level which magnify the speed of water during the filling and draining process we will have a perfect tidal power plant. The oldest and largest tidal plant, La Rance in France, has been successfully producing electricity since 1968. Nowadays, the electricity from tidal plants costs a lot compared to other ways. It is expensive and takes time to build up the turbines and the structures, which can be several miles long. On the other hand, the fuel free, always available and green, and the plants are easy to maintain. For example, two operators are needed to run the La Rance plant at night and on weekends. And the plants is durable with little maintenance. Other type of sea energy is current and marine stems. The water in seas are continuously moving. We can use some of the oceanà ¢Ã¢â ¬Ã¢â ¢s energy, but most of it is out of reach. Capturing this energy problem is not a problem, the real problem is transporting it to the land. Generating electricity in the middle of the ocean just doesnà ¢Ã¢â ¬Ã¢â ¢t make sense since there is no one living in the middle of the sea. We can only use the energy near shore. Using Steam Energy (In W.D.S.) Of course, during the process of desalinating water, steam must be produced. And the moving pressurized steam has tremendous energy in it. Energy in steam is held both in heat and pressure. When heat is applied to a water, the electrons begin to move quickly around molecules. The change of a liquid state to a gas state takes place when the moving molecules take to the air because of its rapidly moving electrons. The water molecules up in the air stay away from each other. When very large number of water molecules are heated, and all repelling each other, pressure builds. When this pressure is released, energy can be generated. When the pressure in steam is released, it transfers its energy to whatever it hits, so by putting a turbine or a piston, this steam energy will be converted to mechanical one. This movement can be used to generate electrical energy, or it can use the steam energy directly in steam machines, like steams trains. COMPARISON BETWEEN HYDRO ENERGY AND OTHER RESOURCES In this section I will come over many aspects about hydro energy like the cost of power generation depending on hydro energy. Then, I am going to mention some up and down sides of this energy source. Cost Hydropower on average is the world cheapest way to generate electricity today. No other energy source, renewable or not, can be compared to it. Today, it costs about a cent per kWh (kilowatt-hour) to produce electricity at a typical hydro plant. Comparing to others, it costs coal plants about 4 cents per kWh and nuclear plants about 2 to generate electricity. Producing electricity from hydropower is cheap because of many reasons. For instance, if a dam has been built and generators installed, the energy source becomes free one. They are cheap also due to their firm structures and simple equipment. Hydro plants are reliable and durable, and their maintenance costs are low compared to coal or nuclear plants. 3.2 Advantage The advantages of hydroelectric power are so many. The power created through the use of dams and turbines is not reliant on coal, oil, uranium, or any polluting nonrenewable resources. Unlike other sources of power, it does not create carbon monoxide smoke, nuclear waste or any other harmful materials. The second advantage is when you construct a dam, it can create power for years and years to come. For example, the Hoover Dam in the US was constructed back in 1936 and it still provides a large amount of power to California, Nevada, and Arizona, three of the most power consuming states. Another advantage is aside from initial construction costs, it is simple and cheap to maintain a turbine. The Hoover Dam again has had only one large renovation done in the 90 years ago since it was created. The last up side I want to mention, is about water, the source of the turbineà ¢Ã¢â ¬Ã¢â ¢s power, is one of the earthà ¢Ã¢â ¬Ã¢â ¢s most abundant resources and it is completely renewabl e. The tides, dams, streams and lakes that hydro electric power sources use to generate power are always moving about, and the turbine simply captures the power, converts it and sends it out to the needed areas. Disadvantage While I spend the majority of report explaining the advantages of hydroelectricity, there are a few disadvantages in terms of cost and wildlife damage. The major disadvantage of hydroelectric power, is its initial cost. Building a dam or marine structures is costless thing to do. Another disadvantage is the need of hiring a professional person who can locate where the dam should be built, as well as a place where the water can build up. In addition to that, redirecting the river for a few months while constructing the dam or evacuating a shore and keeping it dry until building the enormous nuzzles, which is a huge project, and will cost billions. Now, to put things in perspective, once a dam is built, all what is basically needed is a few maintenance workers, so costs become low. Secondly, there is a fact that building a hydroelectric power source is terminating the local wildlife. Whatever done, destroying the surrounding landscapes specially for the dam well happen, whether because of building a whole new lake, or because of adding a large wall into an area where fish used to swim freely back and forth hydroelectric power certainl y takes a toll on the natural habitat. Fortunately engineers started to become a little more conscious of the damage, by building smaller dams, or by providing overflow areas so that fish do not stuck being. While these changes are floating to the surface slowly, at least they are being made. Finally, there is the element of social change that can happen because of a dam being built. By their nature, all sources of hydropower must limit the flow of water in order to make them build up pressure to attain maximum results. As the water is limited, towns and villages downstream can sometimes have their water source drained down to a trickle, particularly after multiple dams, waterwheels and simple use of water can dry riverbeds and render some towns without a water source. Overall, though, considering how much potential energy can be gained by hydroelectric power, the disadvantages of hydroelectric power are probably worth enduring, since they produce so little carbon dioxide, and provide an endless source of electrical power to the area. CONCLUSION In this report, I discussed in detail the Hydro power production trend from the past till now. I gave a brief definition of hydro energy and talked about it importance. In the second part, I explained the types of hydro energy that is available in KSA to use. These types are tidal and marine streams energy and moving pressurized steam in water desalination plants. I introduced the way of each process, and its main up and down sides of them. And finally, I compared Hydro energy with other resources of energy in terms of cost, environmental impact, simplicity and durability. I found out that it is in fact the cheapest way to produce electricity, also it has a simple and firm structure that can last for years with a little care.

Essay --
Lower leg pain has been a mystery, with it being named by several different terms. Shin pain that most athletes refer to as shin splints is now being termed Medial Tibial Stress Syndrome or MTSS. Some atheltes under estimate the severity of shin splints by simply having a lack of knowledge. ââ¬Å"In 1974, Clement was among the fist to postulate that ââ¬Å"tibial stress syndromeâ⬠was caused by a periostitis that could progress to tibial stress fractureâ⬠(Craig, 17). Inflammation of the periosteum and also the tibialis posterior lead to MTSS and ultimately a stress fracture. In order to further research about the cause of MTSS, tissue biopsy was performed on 62 patients in a study by Johnell. According to Craig, 2008, Johnell found that there was an increased tissue metabolic activity, like osteoblast proliferation. Osteoblasts are bone cells that attempt to grow new and repair damaged bone. Osteoblast are present often with inflammation, which is a bodies response to in jury. Through this study, Johnell found that 2/3 of his patients had bone damage, which explains why osteoblasts were proliferating. In a later study by Michael and Holdner they suggested that instead of the tibialis posterior, the soleus was a major cause of MTSS. ââ¬Å"They found that 1/3 of the MTSS patients had soleus fascia inflammation and 1/3 had bony inflammation just underneath the fascial attachment into the boneâ⬠(Craig, 17). Inflammation ultimately causes pain. This explains why the soleus is a contributor to MTSS. Athletes who participate in sports like Track and Field where they are in repeated plantar flexion put a lot of pressure on the gastrocnemius and soleus. The gastrocnemius and soleus are consistantly being contracted with every stride and take off for a ... ...8). With out an arch, the soleus is being stretched for long periods of time that causes it to become fatigued and strained which can put pressure on the tibia. It can not be concluded that excessive pronation causes MTSS, but is rather a risk factor. By taping an individuals arch, the amount of pronation can be decreased as well as the amount of pain experienced. Craig also suggests pool work outs once a week to allow for bone healing. I think this is a great idea, and more coaches should implement a pool work out into their weekly routine. Swimming still allows atheltes to have a cardiovascualr work out while giving their tibia's a break. Some atheltes have an extremely high pain tolerance and will continue to practice and perform, with or without treatment. Though with preventative measures like taping and rehab, the treatment of MTSS can hopefully be achieved.

Definition Essay - Can Love be Defined? -- Expository Definition Essay
Can Love be Defined? The other day I was babysitting my three-year-old niece, a most conniving little angel. As she sat gawking at my girlfriend's brother, Matthew, who was eating potato chips, she told me that she loved me "so much." She had already devoured her potato chips, but she obviously wanted more. Many more expressions of love proceeded to drip from her lips. Finally, the question came; "Reg, can I have some more chips?" At first, I thought this little show of bribery was cute and funny, but then I started to think about the true meaning of love. What is true love? Poets, philosophers, religious leaders, and the American media all have different definitions for this word. Too often, love is conceived as doing whatever it takes to get your potato chips. However, true love involves much more than personal satisfaction. Our society uses the term "love" far too lightly. Having been guilty of this offense myself, I admit my guilt. I often say, "I love Mexican food," or, "I love my truck." Love, however, is not just a happy feeling we get when something nice pleases us. Love is a verb. Love is the action of giving yourself totally to one person without expecting anything in return. Love is being willing to put aside your own needs in order to meet the needs of others. Giving up your weekend trip to the beach in order to take care of your sick mother is one example of love. A destitute mother giving up her one piece of bread to feed her sick little boy is another example of love. The ultimate expression of love is being willing to lay down your own life in the place of another. Love is giving, not getting. Too often our love is conditional. We often hear, "I will love you if you meet my needs," or, "I will love you... ...n who did just that. Two thousand years ago, on a hill outside of Jerusalem, Jesus of Nazareth was nailed to a cross. Three nails brutally pierced his hands and feet. Being a Christian, I believe that Jesus died on that cross to save me from an eternity in Hell. Jesus laid down his life in my place. This is the greatest love anyone has ever shown me, and my definition of love comes straight from that historical death. Would I lay down my life for anyone? I would consider going to the gas chamber in the place of very few people; this would be the ultimate test of my love. However, there are smaller ways that love can be shown. Washing dishes for my girlfriend, babysitting my niece, or even taking my mom out to eat are three small ways of showing my love. The next time I tell someone that I love them, I will be sure to follow through with the actions to prove it.

The Awakening: Romanticism, Realism, and Local Color Essay -- Chopin
The Awakening: à Romanticism, Realism, and Local Colorà à à à Imagine being far out into the middle of the ocean and at that moment, having to make a choice between judgment and individuality, death and life? In 1899, Kate Chopin composed a captivating novel titled The Awakening. Throughout Chopin's day, the work was regarded as nonsense and a waste of time on her part. Critics found the main character's rebellion to be foolish and unlawful. At that age, it was believed firmly that women should be nothing less than completely loyal to their husbands and should joyfully care for any children that they had while their spouse was away, hard at work. Edna, the central character, did not follow this standard. She says specifically that she would not give-up herself for her children. She is not one known to submit to her husband's every whim. Chopin brought Romanticism into play in a realistic setting with this individual. To these literary devices, she blends local color. à à à à à à à à à à à à By manipulating Romanticism, Kate Chopin stretches one's imagination and startles one's mind. Romanticism is both a literary and an artistic movement. It took place in the eighteenth and nineteenth century during which people expressed freedom and individuality and emotions in their works. Chopin shows Mrs. Pontellier's display of freedom and individuality when Edna refuses to go in when her husband Leonce tells her to do so; rather, she stays out on the hammock and tells him to proceed inside without her. Romantics also loved exotic places and chose to display a character that follows his or her own heart. Chopin demonstrates this in her work when Edna realizes th... ...because Tuesday night social calls were a pastime, Realism because Leonce believed that Edna should put herself on hold every Tuesday night for company, and Romanticism because she chose not to stay. à à à à à à à à à à à à Kate Chopin is now considered a wonderful author for the same piece that was once prohibited. People realize that she was just before her time. She blended a Romanticism which is now common to out time with a Realism that was true to her time. She enhanced it with a mà ©lange of Local Color into her setting to give a full outlook of Edna Pontellier's world. Seeing everything that she has to go through, which option should be chosen? Would it beà better to live without freedom of individuality or die trying to get it? With all of the pressures that prevailed over Edna, she chose death.

As We Acquire More Knowledge Essay
As we tend to know more about something we tend to take things to another level. This could be challenging for some and for some it may be the thing they were looking for. I agree to an extent that as we acquire more knowledge, things do not become more comprehensible, but more complex and mysterious. However, it highly depends from person to person, the type of knowledge we acquire and lastly the way in which we acquire that knowledge. Going the extra mile for some may be challenging and for some it may be their start of interest. It depends on the type of person you are, whether you are someone who likes challenges or whether you are someone who is afraid to go an extra step into exploring more and more knowledge. For most people acquiring more knowledge may be mysterious because in the end of the day you are putting your shoes in a different zone. This zone might be a zone where you are not comfortable in or a zone where you have not been in there before. For example, studying about a different element that you may have heard of but have not yet gone deep into. Knowledge for some may start to get complex but this is because you end up in a zone you were not in before. However, for some they would not see this as a challenge or complex, but more of the fun they were looking for. Secondly, this depends on the type of knowledge you try and acquire. Some knowledge might require more effort to be put into it and some may require less. For example, if we were to acquire knowledge about something we have been acquiring for a long time, then our sources for this type of knowledge would be easily gathered. However, if the knowledge we try and acquire is new, then it is likely that we will find challenges in finding more information or collecting about it. It also depends on what the knowledge is about. For some, obtaining a certain type of knowledge is an easy task to get a hold of and this may be because the person has experience in this field. Lastly, it highly depends on how we acquire information or the process of acquiring knowledge. How we acquire knowledge depends on several factors such as: knowing a reliable source to get information from, the way this knowledge is been delivered and how interpret it. Having a reliable source to acquire knowledge may be the start of how we can overcome complexity. This is because our source leads us to many materials that we can use to secure more knowledge. The way we are given this source or taught this knowledge also plays a big roll in complexity. For example, if we were taught bad habits in gathering knowledge or the way this knowledge is been taught to us to be dull then we will struggle with acquiring more knowledge. It also depends on how we interpret this knowledge. If we interpret this knowledge with a lot of excitement and concern then it is most likely that we are not going to find problems along the way. In conclusion, as we acquire more knowledge, things do not become more comprehensible, but more complex and mysterious to some extent. This is because this it depends on the type of person you are, the form of knowledge you are obtaining and lastly the process of gathering knowledge.
High School Seniors Essay
Many people believe open lunch should be a privilege extended to seniors who wish to leave the school grounds and adjacent areas during their assigned lunch periods. This privilege is predicated on the belief that students as they enter their final years of high school should be trusted to make mature decisions and act responsibly. Some students wish they could leave only so they could get something to eat other than school food. I understand that not every senior shows the proper maturity and they should be identified and treated accordingly. When it comes to privilages, seniors donââ¬â¢t have many compared to underclassman. Sure, we get a free period as opposed to study hall and a senior skip day, but donââ¬â¢t we deserve more for our twelve years of hard work and effort put into school? Donââ¬â¢t we deserve something that, frankly speaking, makes everyone more aware of our seniority status, something that we can enjoy this year and the other grades can look forward to? That something can be found in probably one of the more controversial topics in high schools, off campus lunches. I understand the school is responsible for us from the time we arrive at school until the time we depart, and being able to have an off campus lunch would mean we are still the schoolââ¬â¢s responsibility, even though weââ¬â¢re not on campus. However, what if parents were to sign a note stating their child is allowed to leave school during lunch hours and would be their responsibility? If anything was to happen to a student, parents would not have the right to run into school, arms flailing wildly, blaming whomever they can for what happened to their child. But isnââ¬â¢t it time that the school lets us depend on ourselves in making the better decisions, which in this case would be coming back to class in time. We are going to go from being monitored all day long to a college environment where we are the ones to decide what to do. Pupils who fail to meet their responsibility may forfeit the privilege altogether and may be subject to other disciplinary actions. The school should develop rules and regulations that promote compliance with the policy and ensure that only eligible seniors utilize the privilege of open lunch.
