A visit to Ashford hospital Essay Example A visit to Ashford hospital Essay A visit to Ashford hospital Essay Essay Topic: The Visit On the 11th March 2002 we visited the Ashford hospital where we were shown the x-ray department and a radiographer who gave us a talk for about an hour and a half. In my report I will include most of the aspects in x-rays and at last two in detail, starting from the basic definition of an x-ray to how and why we use them to the effects of x-rays.First it is important to know what an x-ray is: x-rays are high photon energy (that is to say short-wavelength) electromagnetic radiation. They are used in medicine both for diagnosis (radiography) and for therapy (radiotherapy). It is not possible either to reflect or to refract x-rays and therefore x-rays cannot be focused.There are three types of radiation from radioactive materials: Alpha (?), Beta (?), Gamma (?).The term radiotherapy refers to the treatment of a medical condition (usually cancer) by means of X-ray, Y-rays or beams of energetic electrons. X-ray radiotherapy falls in to two main classes-superficial therapy and megavoltage (or MV) therapy.Superficial therapy is used to treat conditions of the skin and surface tissues. The tube voltages employed are such that the X-rays have low penetrating power and therefore cause littlie damage to the healthy tissue beneath the area being treated.Megavoltage therapy is used to treat the condition inside your body and has almost completely replaced the lower voltage techniques once used for this purpose. The electrons used to create the X-ray are accelerated to the enormous energies required in a linear accelerator (LINAC).Advantages of MV Therapy- It decreases the damage sustained by the patients skin. The beam is so penetrating that hardly any of its energy is absorbed by the skin and surface tissues.- It reduces damage to the bone.Rotating BeamsThe purpose of radiotherapy is to destroy malignant (i.e Cancer) cells whilst doing as little damage as possible to the healthy tissue and bone around them. One way of achieving this is to aim the beam at the tumor from a n umber of different directions, i.e. to rotate it about the tumor. This technique is known as multiple beam or rotating-beam therapy and produces a considerable cumulative effect at the tumor but a much-reduced effect everywhere else.Treatment PlanningAny amount of radiation is potentially harmful to the person being exposed to it and therefore it is important that the following considerations are taken into account.- The likely benefits of exposure to radiation must outweigh the risks involved.- The radiation does must be the minimum consistent with obtaining good quality images or destroying malignant cells.- It must not be possible to obtain equally useful information by less risky methods.- The beam must be collimated so that only part of the body that needs to be exposed is exposed.- Increasing the PD across an X-ray tube increases the penetrating power of the X-rays produced but it decreases the proportion of the beam that is attenuated by photoelectric absorption, and therefor e decreases the contrast of the X-ray image. The PD should be high enough to produce the required degree of penetration but not so that there is insufficient contrast. Another consequence of increasing the tube voltage is that it increases the energy, and therefore the penetrating power, of the scattered radiation. This increases the likelihood of the patient receiving a significant radiation dose in parts of the body some distance away from the part being exposed intentionally. It also increases the chance of scattered radiation escaping from the patient a potential hazard to hospital staff in the vicinity.- The radiographer must employ good techniques so that repeat exposures are not required. (This is an important consideration when assessing just what is the minimum dose an underestimating would necessitate a second exposure and therefore an overall increase in dose.)A metal filament (usually tungsten) is heated and some of the electrons acquire sufficient thermal energy to es cape from the surface. The higher the temperature the filament is heated to, the greater the number of electrons that are in effect boiled off. This filament forms the negative cathode. These electrons are accelerated across an evacuated X-ray tube towards the positive anode by a large voltage that is applied across the tube.These electrons strike the anode where 99 % of their energy is converted to heat with less than 1 % resulting in X-radiation. One theory, which is very important to the theory behind X-ray, is the Band theory.The continuous background (or bremsstrahlung radiation) is produced by electrons colliding with the target and being decelerated. The energy of the emitted X-ray quantum is equal to the energy lost in the deceleration. An electron may lose any fraction of its energy in this process. The most energetic X-rays (ie. Those whose wavelength is ?min). X-rays with longer wavelengths are the result of electrons losing less than their total energy.The line spectrum is the result of electron transitions within the atoms of the target material. The electrons that bombard the target are very energetic (100keV) and are capable of knocking electrons out of deep-lying energy levels of the target atoms. (this corresponds to removing an electron from an inner orbit on the Bohr model). If an outer electron then falls into one of these vacancies, an X-ray photon is emitted. The wavelength of the X-ray is given by E = hc/?, where E is the difference in energy of the levels involved, c is the speed of the light and h is Plancks constant. Since the energy levels are characteristic of the target atoms so too are the wavelengths of the X-rays produced in this way.For example, when calculating the wavelength of the most energetic X-rays produced by a tube operating at 1.0 * 10^? V (h = 6.6 * 10^-34 Js, e =1.6 * 10^-19 C, c =3.0 * 10^8 ms-1.)The most energetic X-ray are those produced by electrons which lose all their kinetic energy on impact.KE on impact = wo rk done by accelerating PD= 1.6 * 10^-19 * 1.0 * 10^5Maximum KE lost = 1.6 * 10^-14 joulesThe energy of the corresponding X-ray quantum is hc/?min and thereforehc/?min = 1.6 * 10^-14i.e. ?min = (6.6 * 10^-34 * 3.0*10^8)/1.6 * 10^-14= 1.24 * 10^-11 mJust clarify:(max. photon energy) Emax = eV and ?min = hc/eV(where V is the Potential difference)Band theoryIn an isolated atom, the energy of an electron depends mainly on its distance from the nucleus. An electron has a negative charge and a nucleus has a positive charge, and as an electron falls towards a nucleus it loses energy. The energy of one electron in an atom is also affected by the presence of all the other electrons within that atom, since they all have negative charge and so repel one another.If atoms are very close together, as in a solid, then the energy of each electron is affected by the nuclei and electrons of many nearby atoms. This has the effect of smearing out the energy levels into broad bands. The electrons are no t longer restricted to certain well-defined energies; instead, there are broad ranges of allowed energy, and higher energy band is shared between atoms. If an electron has enough energy to be in this band, then it can break free of its parent atom and move through the solid, i,e it can take part in conduction, so this upper band is called the conduction band. If, however, an electron is still bound to its parent atom then it cannot be moved around freely and it is said to be in the valence band. Between the two bands is a range of energies known as the forbidden gap. As shown in the diagram below.The size of the forbidden gap determines whether a given material is a conductor or an insulator. In metals, the conduction and valence bands overlap, so the conduction band always contains electrons, and so metals are good conductors. In insulators, the conduction and valence bands are separated by a large forbidden gap, and the conduction band is virtually empty. To promote an electron fr om the valence band would require a large amount of energy. In a semiconductor there is still a gap, but the range of the forbidden gap is much smaller. If the energy supplied by heating or by allowing the material to absorb photons, then some electrons gain enough energy to cross the gap and enter the conduction band. The more energy supplied the more electrons are promoted, the resistance of many semiconductors fall with increasing temperature.The X-rays emitted from an X-ray tube have a range of energies, which is called the X-ray spectrum. These X-rays are produced by two different mechanisms, which are distinctive in the resulting spectrum.Continuous spectrum (approx 80% of the output)The electrons pass close to the positive nuclei of the target atoms and are slowed down. he kinetic energy that they lose is converted into photons of electromagnetic radiation which have a continuous range of energies up to a maximum value equal to the tube voltage applied.Continuous spectrum A continuous range of photon energies (up to a maximum) is produced as electrons are decelerated in the target.Characteristic spectrumSome of the electrons penetrate deep into the target atoms, ejecting orbital electrons from the innermost shells near the nuclei. Orbiting electrons from outer orbits fill gaps in the inner shells and emit photons that are characteristic of the target atom. As long as the target has a high enough atomic number, the resulting photon will be the X-ray range.Tungsten is used as the target material for nearly all X-rays tubes because it has a high atomic number and so yields high X-ray outputs and a high melting point to withstand the large amount of heat produced. The characteristic K line spectrum produced bt Rungsten is about 709 keV, which is a tube voltage used for many exposures.Line SpectrumA limited of precise characteristic photon energies is generated through electron transitions to the K and L shells.Focal Spot sizeIdeally the X-rays produced wo uld originate from a point source, which would result in a clear shadow being formed with sharp edges (like a light image formed in a pin hole camera). This is not practical because of the great amount of heat being produced by the X-ray tube. If all the electrons were directed at one tiny point, the target would melt. The target is therefore designed to increase the actual target focal spot while keeping the projected focal spot as small as possible, thus keeping the amount of geometric blur to a minimum. This is achieved by using a disc shaped anode with the target area shapely angled and spinning throughout the exposure.Positioning the film as close as possible to the patient also reduces geometric blur.So how do we select exposure?To see why different exposures are selected for different areas, the methods by which an X-ray beam is attenuated must be studied.Simple scatterThe incident photon energy does not have sufficient energy to remove an electron from its atom so it is simp ly deflected from its course without loss of energy. This scatter is proportional to the square of the atomic number.Photoelectric EffectThe incident photon gives up all of its energy to an inner orbital electron, ejecting the electron from its atom. Some of the energy of the electron is used in overcoming the binding energy of the electron. The vacancy in the shell will be filled by electrons in orbital further from the nucleus, producing characteristic radiation, which in the case of the X-ray photons interacting with the body tissue are small and in the infer-red part of the EM spectrum. Photoelectric attenuation is most useful to diagnostic imaging because the photoelectric absorption is proportional to the cube of the atomic number.Compton scatterThe energy of the photon is much greater than the binding energy of the electron. Only part of its energy is given during the interaction with the outer electron. The photon continues in a different direction with reduced energy and th e electron dissipates its energy through ionization. It is independent of the atomic number.Simple is a problem as it reduces image sharpness and increases low-energy absorption in the patients skin. Photoelectric absorption is useful because, as it is proportional to the cube of the atomic number of the absorbing material, it produces contrast on the image. Material of high atomic number absorb more X-rays by this method and those of low atomic number absorb less. As the tube voltage is increased photoelectric attenuation tends to fall and Compton scatter to rise in importance, and as Compton scatter is not proportional to the atomic number of the absorbing material, the contrast is reduced.How do we reduce scatter?- Reduce the beam size by using an adjustable diaphragm, this reduces the field size and thus reduces the random scatter produced.- Use filtration on the X-ray beam to reduce the lower energy photons that result in simple scatter, allowing photoelectric attenuation to do minate.- Use of compression to make the part X-rayed thinner.So what is the radiographer doing?When taking a simple X-ray, the radiographer must:- Choose the tube voltage- this is usually in the range 60-120kVMore kV increases maximum photon energyIncreases average photon energyIncreases total intensityEffect of changing tube voltage on resulting X-ray spectrum.* Choose the tube current this depends on the number of electrons crossing the tube per second. This is controlled by the filament current, which determines the rate at which electrons are emitted from the cathode.Increasing tube current increases the overall intensity but does not increase the maximum photon energy or change the shape of the spectrum.Increases the blackening of the filmIncreases the absorbed dose by the patient.Increases the heating of the target.Effect of the tube current on X-ray spectrum* Choose the expose timeIncreasing the exposure timeIncreases the blackening of the filmIncreases the patient absorbed doseIncreases the chances of movement blur* Choose the focal spot sizeIncreasing the focal spot size increases the tube current and the voltage that can be applied but reduces geometric unsharpness.How do we stop scatter from getting to the film?We use a grid formed by rows of lead strips stops the scattered radiation from reaching the film. To get rid of the grid lines on the image, the grid may be moved during the exposure.We can also use an air gap to reduce the scatter reaching the film.And what about the film?If we were just to use film just to record the X-ray that were transmitted through the patient we would have to use very large exposures because up to 97% of X-rays pass straight through the film without affecting it at all. We therefore use special cassettes that contain fluorescent screens. These fluorescent screens absorb the X-radiation and re-emit visible radiation in a pattern that is the same as that of the original X-ray beam.Construction of the Rotating Anode Tube InsertFluoroscopy:In X-ray fluoroscopy, X-rays are passed through the patient and onto a fluorescent screen to produce an immediate visible image. This has the advantage over photographic film in that it allows dynamic processes. Sadly, unacceptably high X-ray intensities would be needed to produce image that could be viewed directly. A device known as an image intensifier can increase the brightness by a factor of over a thousand and allows the radiation dose to be cut by up to 90% of the unintensified level. The intensifier has a fluorescent screen in contact with a photocathode. This combination converts the X-rays first to visible photons and then to electrons. The number of electrons at any point on the photocathode is directly proportional to the X-ray intensity transmitted by the patient.The electrons produced by the cathode are then accelerated through a potential difference of about 20 kV, using a series of focusing anodes, towards a second fluorescent screen. The increase d energy and concentration of the electrons creates an image that is very brighter than that on the first screen, and which is usually picked up by a TV camera and fed to a TV monitor or video recorder.Fluoroscopy is a technique that is used sparingly, for despite image intensification, the radiation dose to the patient is still significantly higher than that I a standard radiographic examination. Dose savings can be made by using short bursts of X-rays rather than a truly continuous exposure, but even so the examinations remain relatively dose-intensive.Bibliography:For my report the sources which I used were; the textbook Physics A-level by Roger Muncaster, also the textbook Salters Horners Advanced Physics, a leaflet given to me by the Ashford hospital and finally my own knowledge.Conclusion:You can obviously tell that the visit to the hospital was very informative and helpful. Funnily enough at the time I was writing this report I had broken my wrist and was treated at the Ealin g hospital. On my last visit, to take the full plaster cast off I asked the radiographer if she could give me copy of my wrist, but unfortunately she said that it had to go in report. Instead she let me get my hands on some unwanted X-rays, which was the next best thing, so included them in my report.

Radar Coastal Surveillance Essay Example | Topics and Well Written Essays - 5000 words

Radar Coastal Surveillance - Essay Example The primary aim of the present research is the determination of the extent to which radar systems efficiently and effectively execute the requirements and tasks associated with coastal surveillance. Hew (2006), a defence systems analyst with the Defence Science and Technology Organisation, contends that no single radar system is capable of fulfilling the stated tasks and responsibilities but that coastal area characteristics have to be matched against specific systems. In other words, the selection of the coastal radar selection system is dependant upon the characteristics of the coastal area in question and no radar system addresses the needs and features of all. Proceeding from an acknowledgement of this argument, this study will review all of radar technology, coastal surveillance requirements and existent methods for radar coastal surveillance to determine the optimal system, or systems for the execution of coastal surveillance responsibilities.As a strategy for responding to the selected researched question and satisfying the research's articulated aim, an in-depth investigative exploration of radar technology, coastal radar systems, and the requirements of coastal radar surveillance shall be undertaken. The results of the investigation shall determine the optimal coastal radar surveillance system(s).Prior to presenting the data upon which the discussion pertaining to the research question shall be based, it is necessary to contextualize the report's focus. This shall be done through a review of the definition for radar systems, an historical analysis of its development and the articulation of its responsibilities and tasks. 2.1 Background Practically all systems, from computer and communication systems to air and naval defense systems may ultimately be identified as multi-tasking technological networks, comprised of several asynchronous parallel distributed operations and whose total response is, by definition, both complex and probabilistic. Further evidencing the inherently complex nature of systems is the fact that operational responses vary in accordance to output events

Art history from 1580-1980 Essay Example | Topics and Well Written Essays - 250 words

Art history from 1580-1980 - Essay Example This was 1793 painting of nude man with an appearance a real classical young man. Other paintings before 1800 that show naturalism are Francisco Goya’s paintings named â€Å"And so Was His Grandfather† and â€Å"You who cannot†. Artists highly engaged with the nature from 1580-1980. They did this by spending their time to study nature. They started shifting from religious and supernatural paintings to nature paintings. They engaged with nature in their art by portraying objects in their arts as they appear exactly in reality. This was done based on the artists’ scientific knowledge. There was a strong connection between science and art. Examples of paintings that depict nature include John constable’s â€Å"The Hay Wain† and Joseph Mallord’s â€Å"Snowstorm: Hannibal and Army† (Rothko & Rothko 65). Other nature paintings include Theodore Gericault’s â€Å"The Raft of Medusa† and William Blake’s â€Å"Dante Running from The Three Beasts†. All these were painted after 1800. Nature was depicted in the renaissance arts in various forms. For instance, it was presented in paintings, sculptures and music during that period. Naturalism was significant to many artists and movements. For instance, it was significant to humanisms movement. During the renaissance period the society had started to focus more on human values than religious values. As such, artists painted humans in the natural world to show their position on earth. Nature was also significant to naturalism movement where artists were recognized based on how well their represented nature in their paintings. Nature became a source idea for many artists. They got their ideas by simply studying or observing it (Rothko & Rothko

Novel/Movie Difference Mary Shelleys Frankenstein Essay -- essays rese

In reading the book Mary Shelley’s Frankenstein, and watching the by the same title, I discovered several large differences. Primarily, the edited and modified parts were changed to make the movie more interesting. In the book, Marry Shelley described everything in great detail. She included details that may not pertain to novel’s storyline directly, but more to the timeframe of the novel. When a movie comes out made after a specific novel, the screenplay eliminates most of these minute differences. For example, the letters in the beginning of the novel were depicted as high action scenes rather than in letter format. The introduction of the movie was my first difference listed. In the book, the captain of Frankenstein’s ship, R. Walton, wrote letters home to his sister about his voyage to the north pole. In the movie, it depicted these letters as action sequences happening in real time. A couple of in-depth differences in the introduction that jumped out were the big storm at the beginning and how the boat hits a bunch of Ice. Also they see Frankenstein’s monster in a dogsled. One very important difference was the absence of a background story for Elizabeth. In the movie, you have no idea where Elizabeth came from. She could have been born from a cow or something. She could have been released from purgatory to relive her life in the midst of the Frankenstein family. The story of Frankenstein’s youth was trimmed back to a mere twenty minutes as opposed to one-third of th...

In Murmuring Judges, David Hare uses Barry to represent the stereotypical bent policemen that were seen as typical in the late 1980s and early 90s

In Murmuring Judges, David Hare uses Barry to represent the stereotypical ‘bent’ policemen that were seen as typical in the late 1980s and early 90s. Through Barry, Hare shows not only corruption in the police force, as evidenced by Barry planting the Semtex, but also suggests that the police were overworked and under budgeted, â€Å"too much overtime†. Here, Hare shows the dichotomy of sympathy for the police alongside corruption, as he shows Barry to be trying to do is job in difficult times, however, the overarching role of Barry is to show corruption and immorality in policing. Throughout the play, Hare shows the effect of the 1984 Criminal Evidence Act, intended to make policing more about paperwork, and shows how the police feel it is undermining their job; â€Å"we should all just sit in the nick and make policy drafts† highlights how this has changed the nature of policy. Barry is presented as against this, and continues to use older methods of policing, â€Å"It’ my method. † Through this, Hare portrays police corruption, as Barry’s methods are often immoral and even illegal. Hare also presents Barry to see some crimes as â€Å"boring† and â€Å"pointless†, which suggests he is only interested in crimes he can get a good result for, such as bringing down Travis and Fielding in Gerard McKinnon’s crime. Hare also shows Barry to think police resources are wasted by saying â€Å"and yet look at us†, highlighting his personal frustration as again shown by â€Å"please tell me, what is the point? † Interest, Barry seemingly has the same perception of lawyers as the audience have through Sir Peter, suggesting they are â€Å"rich bastards† who participate in â€Å"tax evasion†. It could then be argued that Barry feels justified in his corruption, as the government is also corrupt, â€Å"the government happily lets rich bastards walk away with†. â€Å"You used to be smart† suggests Barry wasn’t always corrupt, which again suggests his actions are due to his frustration at the justice system. The relationship between Barry and Sandra gives the audience insight into both Barry’s character and feelings towards women at the time. Although there is a difference in rank between the pair, DC to PC, Barry is never shown to treat men in a lesser position with the same patronising manner he uses towards Sandra. Here, Hare portrays sexism within the police at the time, which is furthered by Sandra and Barry’s affair, as it could be argued that Sandra is stereotypically ‘sleeping her way to the top’. Hare shows Barry to â€Å"get a kick out of secrecy†, which is in reference to his affair but is also evidenced in his corruption, as no-one else is portrayed in this manner. The fact that Barry is shown to be â€Å"relieved at the change of subject† from his corruption could suggest that he is ashamed, as he is â€Å"able to relax† once they are discussing something else. However, Barry’s lack of personal morals as highlighted in his relationship with Sandra, â€Å"I waited for you†¦I had a rugby match†, which suggests a general disregard could be used to argue that Barry most likely is indifferent about having planted the Semtex. This representation of the police as reckless and immoral suggests Hare views the police in a negative light as they would allow innocent men to go to prison, as shown by Gerard. This was undoubtedly influenced by high profile cases such as the Guilford Four or the Birmingham Six, where men were unjustly sent down for bombings. I did my trick. It always works† suggests the extent of Barry corruption, implying he has framed people before, but more importantly, he knows he can get away with it, through which Hare shows the dangers of immorality in the police. â€Å"You should go on Mastermind† in reference to Barry shows that he is a respected figure in amongst the officers, with which Hare coul d suggest that Barry was in a position to spread corruption throughout the force, as he is admired by the lower ranks. Hare uses this again to highlight the danger of immorality and corruption in the police. Earlier, Barry is also presented as part of the ‘boys club’, as Hare shows banter between the male officers, â€Å"I was conducting an interview†¦ with the barmaid†¦ horizontally†, suggesting that Barry is one of the ‘lads’. Increasingly, Barry is presented as a misogynist and a racist throughout the play, not only towards Sandra but also towards Irina and Gerard. This attitude is shown through the dialogue between Barry and Irina on pg101; â€Å"I don’t take lectures† towards Irina suggests he sees her as beneath him. However, Hare also uses this scene to strengthen the presentation of Barry’s disliking towards lawyers, as shown by â€Å"when was the last time anyone was sick on your wig†, which suggests Barry sees lawyers as out of touch with the real job of justice. This is furthered by â€Å"why don’t you go sit on a committee, ironic as Irina does exactly that at the end of the play, which shows Barry to believe lawyers to be bossy, and â€Å"something-must-be-done’rs†, as Beckett describes them, but ultimately to be useless. At the end of the play, as earlier mentioned, Irina decides to try and change the justice system; in contrast, Barry is presented as exactly the same, as he is still frustrated at the system, â€Å"if they spent half the time trying to support the coppers†. In the earlier scene, Hare portrays Jimmy as out of the club, which is highlighted by Barry saying â€Å"English sense of humour†, again showing Barry to be part of a very, male dominated system. Hare also presents Barry as casually racist here, as there is no evidence that Jimmy is not English, an attitude which is also shown by Barry towards Gerard, â€Å"he was kind of Irish†, a reference to the negative view of the Irish at the time due to the IRA. This also shows the system to be casually racist, as we see that because Gerard is Irish, it is much more believable that he would plant explosives. Hare shows this to be wrong through his portrayal of Gerard, who is hugely different from the stereotype of a criminal. To a lesser extent, police corruption is also shown by Barry’s treatment of Keith, as Barry is suggested to have â€Å"promised him a caution† suggesting Barry was using bribery to get Keith to cooperate. Overall, despite the suggestion of sympathy for Barry as someone trying to do a difficult job, Barry is largely presented as everything Hare dislikes about the police, as he is shown to be racist, corrupt, immoral and misogynistic. Hare uses Barry as an example of wider police corruption, suggesting that Barry isn’t an isolated case but the whole system is corrupt. Barry is juxtaposed against Sandra who is shown to be conscientious and willing to make a difference. However, Hare presents all characters trying to make the system better as isolated and seen as inferior, as shown with Irina, whilst Barry is shown as ‘one of the boys’, overall suggesting that people like Barry will ultimately continue with â€Å"their method† whilst Sandra and such will fail to make a difference. This representation is shown to be the worn outcome for Hare, who is a supporter of change but this represents the reality of policing at the time.

Abraham Lincoln And A New Birth Of Freedom - 851 Words

On April 20th I ventured out to Howard University to visit the renowned Founders library. After signing into the guest book in the library, I set out exploring through the book stacks for a book that spiked my interest. After around twenty minutes I laid my eyes on a book titled â€Å"Abraham Lincoln and a New Birth of Freedom; The Union and Slavery in the Diplomacy of the Civil War† by Howard Jones. While I have studied the civil war in high school history class, my studies focused more on the actual war and its outcomes, rather than the tension leading to the outbreak of war. The book focused on the role of Abraham Lincoln on civil war diplomacy along with how the events specifically regarding slavery through the 1850’s contributed to the increase of sectionalism and the outbreak of the Civil War. I focused my reading on examining the role of slavery in inciting the civil war. The basic premise behind this discussion was that the nation was split into two parts based on Agriculture and Industrialization. The north relied on getting raw goods from south such that they could create processed goods with their strong industry and manufacturing, while the south focused on producing the raw goods through their slave power and agriculture. However, while the north relied on slavery in the south to produce raw goods, they could also obtain raw goods from other nations and hence their economy was not limited by the south, and most importantly by slavery.
