Nanopatches for Improved Vaccines - Summary free essay sample

He was concerned that the existing vaccines, in the form of needles and syringes, weren’t adequate. Kendall and his multidisciplinary team, based at the Institute for Bioengineering and Nanotechnology in the University of Queensland, designed a Nanopatch which is essentially a postage stamp sized wafer of silicone with projections on the one side covered with dry vaccine. The projections, when applied to the skin, penetrate the outer layer containing the body’s immune cells. Within the watery environment of the cells, the projections release the vaccine within minutes, at which time the patch can be removed. The Influenza vaccine was applied to the nanopatch, which was then tested on mice. This method of vaccine delivery was equally as successful in achieving immunisation as alternative methods (i. e. needle and syringe) and only required a hundredth of the usual dose. Other vaccines, including the human papilloma virus (responsible for causing cervical cancer), have also proven to be successfully transferred via the nanopatch. We will write a custom essay sample on Nanopatches for Improved Vaccines Summary or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is anticipated that vaccination costs will be significantly reduced with use of the nanopatch. Manufacture of the patch is relatively inexpensive with lower dosage required per vaccine, and no refridgeration required due to it being a dry vaccine. Refridgeration is the biggest cost involved in the use of current liquid vaccines. Due to the simplicity of the patch, staff will not require extensive training in its application. Another benefit is that needle stick injuries will be eliminated. Pain and fear, associated with injections, will also be removed. Production of the nanopatch in large quantity was always intended, so it could be available for widespread use. As vaccination in developing countries is a major focus of the Bill and Melinda Gates Foundation, they have provided funding for this project. 15 million has also been invested, by a private organisation, to Vaxxas a company which has been established to market the nanopatch. The nanopatch is to undergo further development and clinical trials, before hopefully being available in 5 to 10 years.

Aircraft Winglets Essays

Aircraft Winglets Essays Aircraft Winglets Paper Aircraft Winglets Paper Aircraft  Winglets Many of us who fly regularly have most probably seen a so-called winglet or wingtip device at the end of the wing of an airliner at least once. It is showing up more and more often on more and more types of aircraft, thus we felt it’s time to give an overview to our readers about these sometimes funny, sometimes cool and stylish looking aircraft parts. History, Reason and Benefits The initial theoretical concept goes back to times before even the Wright Brothers first took to the skies in 1905, but it was picked up and developed by Richard T. Whitcomb of NASA after the 1973 oil crisis – in order to reduce fuel consumption. The first tests were carried out in 1979/80 in cooperation with the U. S. Air Force. At almost the same time, but independent of any U. S. military organization, a private jet producer, LearJet exhibited a prototype in 1977: the LearJet 28 that featured the first winglets on a jet and a production aircraft. Flight tests made with and without winglets showed that the winglets increased range by about 6. 5 percent and also improved directional stability for the LearJet- these two factors are the major reasons behind using this facility at any fixed wing aircraft ever since. A winglet is a (near) vertical extension of the wing tips. The upward angle of the winglet, its inward angle as well as its size and shape are critical for correct performance – this is why they can look quite different. Air rotating around the wing strikes the surface of the winglet that directs it in another direction – thus creating an extra force, basically converting otherwise wasted energy to thrust. This is a small contribution but can save a lot for an operator in an aircraft’s lifetime. Another potential benefit of winglets is that they reduce the strength of wingtip vortices, which trail behind the plane. When other aircraft pass through these vortices, the turbulent air can cause loss of control, possibly resulting in an accident. Winglet Types In general any wingtips that not end the wing simply horizontally are considered as some kind of a winglet. Even though in strictly technical terms Wingtip Fences are not real extensions of the wing, and Raked Wingtips do not have a vertical part, they are still widely considered as winglet variants. WINGTIP FENCES are a special variant of winglets, that extend both upward and downward from the tip of the wing. Preferred by European plane-maker Airbus, it is featured on their full product range (except the A330/340 family and the future A350). The Airbus A300 was actually the first jet airliner to feature this kind of solution by default, but it was a very small version of the tool. Provided that most of the Airbus planes (including all A320 family jets) feature such wingtip fences, this may be the most seen and most produced winglet type. Even the new Airbus A380 double-decker features wingtip fences. Airbus Winglets as seen from the outside Airbus Winglets as seen from onboard BLENDED WINGLETS (the real â€Å"Winglets†) are the most popular winglet type, leveraged by Airbus, Boeing, Embraer, Bombardier but also by Russian Tupolev and Iljushin. Blended winglets were first introduced on the McDonnel Douglas MD-11 aircraft in 1990 with launch customer Finnair (it also features a smaller winglet at the bottom side of the wing). In contrast to Airbus who applies the wingtip fences by default on most of their aircraft (and the winglets on the A330/340 family), lended winglets are considered by Boeing for example as an optional extra feature on their products, except for the Boeing 747-400. For some of the older Boeing jets (737 and 757) such blended winglets have been offered as an aftermarket retrofit, these are the newer, tall designs and do not connect to the tip of the wing with a sharp angle, but with a curve instead. These winglets are popular among airlines that fly these aircraft on medium/long haul routes as m ost of the real fuel savings materialize while cruising. Longer flights  mean longer cruising, thus larger fuel savings. And they also server as marketing surface for airline logos or web addresses usually. Just recently the Boeing 767-300ER has received 3. 4 m high (! ) winglets produced by Aviation Partners Inc. with American Airlines as the launch-customer with Air New Zealand and Hawaiian Airlines following with orders of 5  and 8 aircrafts respectively. 141 shipsets have been pre-sold  already as the forecasted fuel savings  range  around  4%-6% for medium/long-range flights. Airbus earlier tested similar blended winglets designed by Winglet Technology for the A320 series, but determined that their benefits did not warrant further development and they stayed with the wingtip fences instead. Aviation Partners Boeing  claims that winglets on 737s and 757s have saved a collective 1. 2 billion gal. of fuel since they were introduced and 11. 5 million tonnes of CO2 while reducing those types’ noise footprint by 6. 5%. It has sold winglets to 140 airlines and 95% of all 737NGs are fitted with them. It is working on four winglet concepts for the 777 and hopes to finalize a design for that aircraft type by December, 2008. Blended Winglets on Several Aircraft Types RAKED WINGTIPS are the most recent winglet variants (they are probably better classified as special wings, though),  where the tip of the wing has a higher degree of sweep than the rest of the wing. They are widely referred to as winglets, but they are better described as integrated wingtip extensions as they are (horizontal) additions to the existing wing, rather than the previously described (near) vertical solutions. The stated purpose of this additional feature is to improve fuel economy, climb performance and to shorten takeoff field length. It does this in much the same way  as â€Å"traditional† winglets do. In testing by Boeing and NASA, raked wingtips have been shown to reduce drag by as much as 5. 5%, as opposed to improvements of 3. 5% to 4. 5% from conventional winglets. Airliners to use raked wingtips: Boeing 747-8, Boeing 767-400ER, Boeing 777(-200LR; -300ER; and freighter versions) plus the new Boeing 787 Dreamliner and the Airbus A350. The 747-8, the 787 and the A350 will have special, new kind of wings, which do not have a separate winglet, but have raked, and blended wingtips integrated   without a sharp angle between the wing and the winglet. Raked Wingtips on the new Boeing 787 and Airbus A350 As you can see, wingtips/winglets have developed and changed very much over the last 30 years, but are becoming the standard, which is not proven better by anything else than the wing designs of future aircraft by the largest airplane-makers that feature a built-in winglet at the tip of their new, evolutionary wings. Raked wingtip Boeing 787 Dreamliner rollout showing raked wingtip Raked wingtips are a feature on some Boeing airliners, where the tip of the wing has a higher degree of sweep than the rest of the wing. The stated purpose of this additional feature is to improve fuel efficiency and climb performance, and to shorten takeoff field length. It does this in much the same way that winglets do, by increasing the e ffective aspect ratio of the wing and interrupting harmful wingtip vortices. This decreases the amount of lift-induced drag experienced by the aircraft. In testing by Boeing and NASA, raked wingtips have been shown to reduce drag by as much as 5. 5%, as opposed to improvements of 3. 5% to 4. 5% from conventional winglets. [16] While an equivalent increase in wingspan would be more effective than a winglet of the same length, the bending force becomes a greater factor. A three-foot winglet has the same bending force as a one-foot increase in span, yet gives the same performance gain as a two-foot wing span increase. [27] For this reason, the short-range Boeing 787-3 design called for winglets instead of the raked wingtips featured on all other 787 variants. Raked wingtips are installed on, or are planned to be installed on: * Boeing P-8 Poseidon * Boeing 747-8 Freighter * Boeing 747-8 Intercontinental * Boeing 767-400ER * Boeing 777-200LR * Boeing 777-300ER * Boeing 777 Freighter * Boeing 787-8 Boeing 787-9 Anyway The performance of a commercial transport airplane is typically measured in terms of mission capability and operating costs. Mission capability can be improved by reducing airplane drag during takeoff climb and cruise, and by utilizing designs that minimize structural weight. Operating costs can be reduced by reducing airplane cruise drag (hence, resulting in less fuel burn and less fuel costs) and by utilizing designs that are inexpensive to manufacture and maintain. Further, for commercial operators, higher profits can be achieved by being able to transport more customers and/or goods for a given flight. Because the additional payload increases takeoff weight, it is even more desirable to reduce takeoff drag for takeoff-climb-limited missions. nothing new here right ? The objectives of reducing drag, reducing weight, and reducing complexity (hence manufacturing and maintenance costs) are often in conflict. Adding a wingtip extension member can reduce the drag of a given airplane, but this will usually require increasing structural weight IE winglets bend the hell out of wing roots because of the increased moment arm therefore you need to beef up the wing judiciously on shitty wing designs the weight increase can washout the efficiency increase by additing a winglet in the first place.. Sooooooo Weight increases are due to the weight of the wingtip extension member and also due to strengthening required of the existing wing structure in order to support the increased bending moments exerted by the wingtip extension member. Additional weight penalties can also occur if the extension exacerbates flutter. IE if you fiddle with ANY WING design after flight test you change its natural resonance IE it becomes a new tuning fork heaven forbid it will like to resonate at cruise mach IE flutter.. 747 has a speed advantage over the A340 because of flutter the old crusty 747 hauls ass the A340 could haul ass if it didnt like to shake itself apart at VMO.. ( my personal opinion based on 2nd hand info .. This conflict between the benefits of reduced drag and the disadvantages of increased weight has motivated designers to find an optimal balance between the two when designing a wingtip extension member. One such attempt is described in U. S. Pat. No. 5,039,032, incorporated herein by reference. The 032 patent describes a number of wingspan extensions termed High Taper Wing Tip Extensions. These are also known as raked wingtips. Raked wingtips are generally characterized by leading-edge sweep angles that are g reater than the main wing sweep angles and are significantly tapered (i. . , the chord length decreases in the spanwise direction. ) Raked wingtips offer several advantages, some of which are outlined in the 032 patent. These advantages include the aerodynamic benefit of drag reduction due to increased wingspan, and a number of weight-reduction advantages (relative to simply extending the wingspan of an existing conventional main wing. ) Two weight advantages are attributed to the wingtip taper. At high-load-factor structural design conditions, the smaller chords are subjected to less load and they result in less induced loading on the outboard main wing. These are both factors that reduce the bending moment that the inboard wing must support. Two more weight advantages are attributed to leading-edge sweep. The leading-edge sweep of a raked wingtip results in the center of pressure being located further aft than for a simple extension of an existing conventional main wing. At the high load-factor structural design conditions, this relative aft-movement of the center of pressure causes the sections of the main wing adjacent to the raked wingtip to be twisted more leading-edge-down, thus reducing the loading on these sections and the bending moment that the inboard wing must support. The relative aft-movement of the center of pressure also acts to attenuate flutter. The raked wingtips described in patent 032 range from moderate span extensions (e. g. , 6% increase in span) to large span extensions (e. g. , 12% increase in span). It is the large span extensions that offer the greatest benefits. Regardless of these benefits, there are challenges in implementing raked wingtips on some aircraft. For example, on aircraft designed to operate at high subsonic Mach numbers (i. e. , at or greater than about 0. 0) there is a tendency for the boundary layer on the upper surface of each raked wingtip to separate under high-lift conditions (such as during takeoff climb or landing). This boundary-layer separation has the potential to increase drag and to generate premature buffet. The primary motivation for adding a wingspan extension is to increase the lift-to-drag ratio (primarily by decreasing drag), both during cruise and takeoff climb. If there is a significant drag incre ase due to large-scale boundary-layer separation under takeoff climb conditions, part or all of the takeoff-climb improvement is lost. When the raked wingtip boundary layer separates, there is also a possibility of unsteady aerodynamic forces strong enough to vibrate the airplane structure and to be perceived by the airplane pilot as buffet indicating the onset of aerodynamic wing stall. If this form of buffet occurs prematurely (that is, within what would normally be the operating envelope), stall speed must be declared at a speed significantly higher than the aerodynamic wing stall, thus degrading airplane performance. The 032 patent acknowledges the tendency of the boundary layers on raked wingtips to separate under high-lift conditions. In the 032 patent, raked wingtips are categorized into two groups, one group with leading-edge sweep angles between 40 and 50 degrees and another with leading-edge sweep angles between 50 and 60 degrees. For the first group, the 032 patent indicates that some form of a mechanical leading-edge high-lift device (such as a slat) is required in order to avoid premature low-speed buffet. The addition of a mechanical leading-edge high-lift device avoids premature boundary-layer separation, alleviating the buffet problem, but it adds profile drag, weight, complexity, and cost. Under some circumstances, these disadvantages may outweigh the benefits of the raked wingtip. For the second group, the 032 patent indicates that the wingtip leading-edge sweep is great enough to trigger the formation of a stable leading-edge vortex, and that therefore premature buffet will not occur and no high-lift mechanisms are required. The inventors herein have discovered that under some circumstances, leading-edge sweep angles of 50 to 60 degrees may not be adequate to ensure the formation of a stable leading-edge vortex when conventional transonic airfoils are used for the raked wingtip geometry. As used herein, transonic airfoils are those designed to operate at high subsonic freestream Mach numbers, with significant regions of locally supersonic flow. Additionally, even if the presence of a stable leading-edge vortex prevents premature buffet, such a vortex may result in higher drag than if the majority of the raked wingtip boundary layer could be kept attached over the range of typical operating conditions. Further, the technical viability of any raked wingtip would be improved greatly if there was no requirement for a leading-edge high-lift mechanism. Thus, the evolution of the improved raked wingtip, particularly for use with aircraft that operate at high subsonic Mach numbers. The ideal raked wingtip would provide the aerodynamic benefits of an increase in wing span, while avoiding premature boundary-layer separation under high-lift conditions. Further, the optimal arrangement would not add significantly to wing weight or wing complexity. Both the raked wingtip ; the blunt raked wingtip are Boeing inventions. Airbus A330/A340 uses the 747-400 winglet. The A320 family of airplanes uses the AIRBUS ( opps BAE UK developed ) delta winglet that has an opposite plan-form camber on the upper ; lower half of the winglet to gracefully control the direction of the vortices comming off the top ; bottom of the wings to kinda mesh them together non distructively a clever design by a company with a fine British aircraft heritage .. god save the queen .. All that being said winglets on business jets regardless of eficiency increases are for sex- appeal ..

Wise Childrens Narrative Voice Essays

Wise Childrens Narrative Voice Essays Wise Childrens Narrative Voice Essay Wise Childrens Narrative Voice Essay Angela Carters Wise Children is the fictional autobiography of Dora Chance, looking at both past experiences and, from the point of view of the author, real time events. It is written in the first person, from the point of view of Dora Chance, written in such a way as to convey the thoughts and feelings of the narrator without a direct notification of such thoughts and feelings. This means that for Angela Carter to put across Doras feelings and opinions of the events of the novel many other literary techniques must be involved. The narrator herself uses many colloquialisms and phrases, sometimes turning them into puns or twisting them to a different outcome, for example and what does the poor robin do then? Bugger the robin! this addresses the narrators point of view on formalities and stereotypes, allowing the reader to come to terms with her unique style. She acknowledges events and ideas which may be uncomfortable to a modern audience and gently pokes fun at them, for example Ill do it on the horsehair sofa, do what? What do you think? This indicates to the reader that the normal taboos of society do not necessarily apply and that the narrator is open with her view and opinions, this allows the reader to trust the narrator. The point of view of the reader changes as the book progresses, for example, within the first pages of the book the narrator directly involves the reader within the surroundings, for example, Dora states this is my room although the room or any event leading up to entering the room is never described the scene is immediately set and the reader can imagine the room. Carter subtly adds features to the room as the paragraph continues. For example, she suggests the reader take a good look at the signed photos stuck in the dressing table mirror causing the reader to focus on the idea of the object as though they were actually shown around the room. There are at least two instances in which Dora involves the reader as though interacting with them Theres Westminster Abbey, see? careful, the paper is starting to crumble these allow the reader to feel involved and therefore more trusting of the narrator as the book progresses. However occasionally Dora refers to these real-time moments as though in the past tense, for example I squinted as opposed to I am squinting however at the same time describing events in real-time such as She starts to pour out tea as though the event has just taken place and is being recounted for the benefit of the audience, also in these moments it is apparent that no other character acknowledges the presence of the reader. This change in tenses could be for the benefit of the reader, as it would get tiresome to describe all event as they are happening and have no involvement of the reader. In the book time does not appear to be a linear construct. Dora appears to have the ability to stop time to allow the reader to catch up with current events, which she does so with the command, similar to a direction in a piece of drama, freeze frame. During this it appears that the idea of real-time still exists, as Dora moves from the living room to the attic and directly interacts with the reader again. This is similar to the dramatic technique carried out by the chorus of Greek theatre, in which one or more character directly acknowledges the audience and interacts with them alone and can also interact fully with other characters in the play that do not acknowledge the presence of the audience. It is indicated to the reader some time after, and quite unexpectedly that Dora has e-appeared in the living room and time has begun again with a prompt, another technique used in drama, when a command similar to the one above is used press the button for Play, however, it is uncertain to whom she was addressing the command to, she could be directly involving the audience again, as the command had no speech marks, or to herself as a stage direction, or to another character. When Dora describes and explains her family history she does not do so in a straight line, along the way she often refers to characters the reader is unaware of yet, as though she is unaware of this, perhaps she expects she is recalling the stories for her own benefit, as opposed to the benefit of the reader. This means in many places she has to double back on her explanations and descriptions, many times stopping herself in the middle of a sentence to describe something else, for example while showing the reader a picture of her grandmother Estella as Desdemona from Othello she is just about to explain the relevance of the picture when she stops herself, saying wait, Ill explain that later. This technique is supposed to get the reader interested in the events Dora has tactfully not described to them, causing them to read on. Dora often re-tells rumours or stories from other characters, similar to how gossip would be passed on, however this is the first example of where the reliability of the narrator is brought into question, as often stories such as this are retold differently to the original, either deliberately or unintentionally, to make the story seem more interesting or dramatic. Another technique that is used is to talk about a completely different subject after discussing a subject that involves the next subject in some way. For example she describes a story her Uncle Peregrine has told her about her grandmother Estella and then begins to talk about Peregrine, without finishing her story about Estella completely. This gives the impression that this is an after thought, and the narrator is making up as she goes along, improvisation. This gives the narration a natural feel, as opposed to a pre-rehearsed, artificial feel sometimes apparent in other books of this nature; however it can cause some confusion to the reader, who may loose the plot of the novel, making it difficult to understand and thus read, discouraging the reader. The novel is very surreal, in many parts farcical, and some of the events are improbable in real-life. This is a carnivalesque technique and magical realism is used. Much of the surrealism is therefore intentional; however, some of this magical realism could be caused by the narrator herself, who can be described as quite unreliable. Much of the book is based on memory from over 70 years ago, therefore it is understandable that many of the events described in the book cant possible be remembered, for example when Dora was seven she states she can remember going to the pier with her Uncle Peregrine and he was wearing a white suit with a straw bowler hat however this is probably Doras imagination instead of fact, and in a similar way, many of the events could be exaggerated. For example, there was an event in her early twenties of a costume party in which the house caught fire and Dora describes how Saskia was still eating an entire swan in the chaos and everyone was having sex in the garden, this is probably exaggerated. As stated above, the use of a narrator directly involved in the unfolding events is that while describing events that unfold around them they can convey their thoughts and emotions into the scene. A key example of this is the scene just before Tiffany allegedly commits suicide, where she appears on live TV to confront Tristram. Before this scene the tone of the narrator is very brisk and hurried, but mostly cheerful. When the suicide scene unfolds the narrators tone and speed of the novel slows down. The sentences become longer, more eloquent, and expressive. She uses very few colloquialisms and describes her own actions through the scene. This conveys her feelings of worry for Tiffany and uncertainty of what is going to happen through the piece. In conclusion the narrator is what gives the book its unique style and, inevitably, its soul. It allows the reader to imagine the characters of the book as real people, with emotions and faulty memories and opinions, as opposed to a simple and straightforward look of a fictional characters life. Using the narrator Angela Carter has the ability to manipulate linear time and directly involve the reader in the events of the novel.

Managing for the Future Essay Example | Topics and Well Written Essays - 4000 words

Managing for the Future - Essay Example Comparison of the competence that a company will need and the competence that the company is already endowed with 23 9. Conclusion from the comparison 24 Reference List 25 1.0 Introduction The competitive edge of an organization depends upon several contributing factors, and one of them is strategic plan for the future. The strategic plan for the future is a rough guide book that lets the organizations produce a rough sketch (Braithwaite and Hall, 2009). A sketch that may look very rough and unrecognizable but as time progresses the sketch begins to take a definitive shape. In the present context the research reports sheds light on the track record of the management of BP (British Petroleum) oil for the past years. The management strategies and the decisions of the BP management is critiqued and analyzed to reflect its effectiveness (Das and Teng, 2004). The research report then develops a rough sketch of future environmental condition. The environmental condition is prepared based o n the present state of condition, and also based on the way the future spans out. The research report indicates what the management of BP oil needs to do in order to position itself in a better way in the future (Gilbert and Gips, 2000). Lastly the research report produces a comparative picture of the competencies that BP oil is already endowed with and the competencies that BP need to develop. The research report delves into 3 separate areas, one is sustainability, another one is distribution and the third one is corporate social responsibility. 2. Historic analysis of the organization’s performance The historical performance of BP is traced across 3 important areas, which are sustainability, CSR and distribution. 2.1 Sustainability The sustainability of BP is measured across 4 different areas, which are safety, environment, people and performance. Over the last 8 years starting from 2007 to 2013, BP has developed its safety measures (Harland and Branchley, 2003). This led t o the decrease in the number of fatalities, the number of days away from work for the employees. Improved safety measures in the past 7 years also ensured that the numbers of oil spills decrease. Apart from that the amount of greenhouse gas emission has also decreased. The sustainability encompasses other important factors also like the people and performance. The last 7 years data indicate that the numbers of employees have increased sufficiently (John, 2010). Improved employee satisfaction led to the retention of more number of employees. Working in BP requires staying away from home for long durations. So the intake of women in this line of work was always few and in fact negligible. The inclusion of women in its work force indicated the bold stride of BP towards the expulsion of gender bias from the work culture (Kahnmann and Tversky, 2001). In case of performance, there has been tremendous increase in the amount of dividend paid to shareholders and the contribution towards the communities. The sustainability reports indicate that the company invested significantly to ensure that both the environment and the employees are kept from harm’s way. Although the recent oil spill of the BP in the Gulf of Mexico is an indication of the fact that BP has major gaping holes in its safety procedure. 2.2 Distribution The

Engineering ethics Assignment Example | Topics and Well Written Essays - 500 words - 1

Engineering ethics - Assignment Example gained through studying, experience and practice is used to invent ways of utilizing economically the scarce materials and forces of nature to benefit mankind. It is therefore implicit that professional and ethical practices should be upheld to ensure public good is realized. In the recent engineers have failed to remain devoted to upholding high personal honour and professional integrity and accountability as they should in their practice. Despite the fact that their duties are clearly stated in all the phases of an engineering project and they are expected to concentrate on achieving goals set in their area of competence within the time allocated, there are complains of poor quality of work, failure to meet deadlines and failure to adhere by the governing rules especially about environmental conservation. This causes the society to doubt their professional integrity and accountability. Engineers are expected to be faithful to their employers and handle their clients’ information with confidentiality where necessary .It is ethical to be open to their colleagues and disclose anything that can affect their image directly or indirectly to their clients and society at large in order to uphold confidence in professional engineers. Society seeks engine ering services from those who show integrity and good citizenship. (Koen, B.V) Engineering projects are always done in teams, for a effective teamwork members are expected to utilise the skills or their specialists’ knowledge without looking down at others.

Stabilising factor in the cold war from 1949 to 1963 Essay Example for Free

Stabilising factor in the cold war from 1949 to 1963 Essay To what extent was the nuclear arms race a more stabilising factor in the cold war from 1949 to 1963? From the period of 1949 up until 1963 saw increasing developments in nuclear technology by both the two superpowers, the USA and USSR. The race meant that both superpowers aimed to match each other and even gain the upper hand in terms of nuclear missile technology. Nuclear arms were seen as a form of scare tactic against the other superpower as both felt threatened by each others ideological capability. It was also used as a form of defence mechanism in case of future attack however, the power and destruction of the weapons in which these countries created would have proved fatal not only for the opposing country but for the world. The nuclear arms race has been argued that it stabilised relations between the countries especially after the Cuban missile crisis although there is much evidence that proves otherwise, in which relations between the soviets and the United States were as tense as ever. On the 6th of August 1949, the USSR tested the first atomic bomb in the north of what would be now Russia. This was to start a fury of nuclear testing between the nations. However the first testing was actually in 1945 when the United States dropped atomic bombs on Hiroshima and Nagasaki, killing thousands of civilians. This immediately threatened not only Japan, the enemy of the United States during WW2 but also close neighbour, the USSR. Stalin saw the highly powerful bombs as force of power over the world. The United States showed the might and strength of their military weaponry but it made relations between the two superpowers very unsettling. It could be seen in this period, as a settling factor with the policy of Brinksmanship. The policy was formed by Eisenhower, the President from 1953 to 1961 and John Foster Dulles, the Secretary of State. It was a policy of intensely threatening the opposing side with action without delivering the action. In this case the United States were threatening the USSR with Nuclear action. It was a very dangerous policy as the name suggests it would go right to the brink of Nuclear War. This was very much true in the Cuban Missile crisis when the Soviets had nuclear weapons based in Cuba ready to target America, while the Americans had missiles based in Turkey, also ready to attack. Both superpowers were not only within each others sphere of influence, but they were also armed too. If the opposition was not backing down it would lead to two options, to either reveal the false threats or go to war. This policy however was used by both parties which in essence mad the whole of the period of time a very tense time. The false threats could be seen as a stabilising factor as both parties were not going to use the weapons, only as a scare tactic which would lead to an increase in communication between the countries. On the other side, threatening to destroy the opposing superpower could be seen as unsettling the relations even more than it already was. M.A.D. (Mutually Assured Destruction) could also be a Stabilising factor in this period as it caused both sides to rethink their strategies. Both sides had enough nuclear weaponry to annihilate the other and to even counter-strike when hit first. Both sides knew that using this strategy would prove too costly so for their own need they needed another approach. A more flexible approach in which the sides would use smaller, targeted missiles achieving to hit a specific area would be more worthwhile as it would limit the amount of action and devastation that the arms could bring. This agreement to use another approach to Brinksmanship in which it brought threatening words to the negotiations would be another step towards a more steady relationship between the soviets and the U.S. The Leaders of both sides also played a huge significance in terms of the nuclear arms race. The soviet leader Khrushchev who served from 1953 to 1964 was a very unpredictable character. This had made relations with the United States very unsettling especially when he possessed nuclear arms. America was desperate to initiate some kind of direct contact. This direct contact was made when the hot line telephone link was created. This could be seen as a sign of a more settled relationship during the nuclear arms race. It was a form of direct contact between the President, which at the time was Nixon and the Soviet Leader Brezhnev. Created in 1963, its aim was prevent a misunderstanding between the nations with the topic of nuclear arms. It was successful as it gave a quick response to any threats the Soviets made especially when the Soviets pulled out of Cuba, the United States were unsure of what the soviet would do next. The Nuclear Test Ban treaty of 1963 was another sign that the nuclear arms race was a stabilising factor as it banned testing of nuclear weapons above water. This was a huge significance as the previous decade consisted of both superpowers testing and improving nuclear weaponry. The main reason for this was the fact that they got too close in the Cuban missile crisis. They were literally hours from nuclear war. However there other factor that played into the formation of the treaty. The Soviet Union were in economic turmoil especially when they were paying almost a third of their GMP on arms. America was also in turmoil especially with the Vietnam War heating up and domestic issue of civil rights. In conclusion, after looking at the period of 1949-1963, the nuclear arms race was a stabilising factor in the cold war although things could have been the complete opposite. The risk of using Brinksmanship could have ended in war and eventual devastation of the world. Both countries, for their own sake needed to come to some agreement to limit the arms. By using the hot line telephone link both superpowers could prevent each other with great speed which helped misunderstanding especially when Khrushchev had a very unpredictable mind. The test ban treaty of 63 also helped limit the use of unsettling use of the weapons but it dragged other powerful nations such as China and France into the mix when they disagreed against the treaty.
