Reserch proposal - Dissertation Example Recently Saudi airlines have been criticized to be losing its customers due to their inferior customer service quality and poor price strategy. Customer is the heart and soul of any business organization, and if they are not pleased with the service or end product, then the business is doomed to failure. Any business needs to be revolving around the key concepts of customer satisfaction and customer loyalty. If customers are satisfied about a product or service, they keep coming back for more and also can attracts more customers from the potential market. Big airline companies like Saudi airlines, need to keep monitoring their quality of service in order to be top in the airline industry. They should make best use of the CRM programs to enhance their customer relation as well as profitability. According to (Avidian Technologies,2004) â€Å"Good CRM allows all of the information obtained to be shared among both the sales force and the entire company.

Customer is the soul of a business firm, and if they are treated well, then

Cloning: A Nusaince or Necessity :: essays research papers

Cloning: A Nuisance or Necessity   Ã‚  Ã‚  Ã‚  Ã‚  So many miraculous discoveries have been made during the last century. Medical technology has advanced at an unprecedented rate. Now, we are faced with yet another scientific breakthrough. Cloning, in recent years has taken its own shape under the spotlight. However, people are debating whether or not it should be done. I mean, â€Å"Is it morally correct, humane, possible? How will it affect the future of humanity?† There are those who feel that we should step forward and support the idea. Proponents believe that the technology will be used for the good of mankind. Experts say that the technology may be used to help terminally ill patients in a therapeutic way. Others, however, are trying to stop the practice before it has a chance to realize its true potential because they are afraid of future hazards. They think that someone or some country will use the technology to aid them in war. They do not think that it should be accepted because of many of our rel igious beliefs. Opponents of cloning believe the benefits could never outweigh the potentially horrid process.   Ã‚  Ã‚  Ã‚  Ã‚  People who promote the idea of cloning claim that it will probably be used for very good reasons. Today’s list of people needing organ transplants because of disease or deformation at birth could be clearly in only a few years. The technology may advance to a point where children born with missing limbs or deformed parts could actually be removed and replaced with a fully functional, completely healthy limb.   Ã‚  Ã‚  Ã‚  Ã‚  If cloning were ever to reach its full potential, the benefits would be virtually limitless. There would be laboratories where the sole purpose of that lab would be to make replicas of one’s self, so that if the person ever had anything wrong with their body, it could be fixed by simply going and having a surgery that would give them a replacement. It would have matching DNA and would be 100% compatible with the body. In theory, people could extend their lives for hundreds of years.   Ã‚  Ã‚  Ã‚  Ã‚  Who can say that cloning is done for the purpose of medicine. Opposers of cloning claim that the technology is not being developed for the safety of humanity, but by the demand of the people. It is for the people out there who believe that it could give them a new start every time they feel like they are old.

Antony and Cleopatra Essay

Octavius Caesar has a pivotal role to play in Antony and Cleopatra: as a member of the triumvirate (the ruling council of the Roman Empire, composed of three members, the others being Lepidus and Antony), he has the responsibility to run part of Empire, he also has a long-standing rivalry with Antony, and dislike Antony’s relaxed mood, especially his affair with Cleopatra.  We first see Caesar towards the end of scene one, where he is criticising Antony for spending too much time with Cleopatra. Two common habits of Caesar are shown in the first few lines of this scene: It is not Caesar’s natural vice to hate our great competitor  [Antony] †¦ he fishes, drinks and wastes the lamps of night in revel.  (I.iv.2-3a, 4b-5a)  Not only does Caesar like to himself in the third person (â€Å"Caesar’s natural vice†¦Ã¢â‚¬ ) he also has a tendency to criticises anyone who likes to enjoy themselves; this is seen again at the feast on Pompey’s ship. Caesar then goes on to list more of Antony’s faults, as Lepidus, ever eager to stop any arguing, tries in vain to excuse Antony, and calm Caesar down: Lepidus: I must not think that there are  Evils enough to darken all his [Antony’s] goodness.  Caesar: Let’s grant that it is not  Amiss to tumble on the bed of Ptolemy,  [To] keep the turn of tippling with a slave †¦ and stand the buffet  With knaves that smells of sweat.  (I.iv.10b-11, 16b-17, 19, 20b-21a)  Caesar again complaints that both Antony and Cleopatra are committing adultery, and then says that Antony has been drinking too much, and fighting with â€Å"knaves,† which means that he is not focusing on running the Empire, as he should be, and also that it gives a bad impression of the triumvirate and Caesar especially – something that Caesar himself is very worried about, as is seen later. However, Caesar changes tack later on, after his messengers bring word that Pompey is growing in strength, and also that two famous pirates, Menecrates and Menas, are also acting on Pompey’s behalf. Caesar apostrophises Antony, in a scene that is thought by many to be highly significant, as it one of the very few times that Caesar is seen, in the play, to pay a genuine complement to someone. Caesar remembers a time when Antony â€Å"slew’st Hirtius and Pansa, consuls [of Rome.]† Although the imagery that Caesar uses is not particularly pleasant, (â€Å"stale of horses† and â€Å"eat strange flesh,†) it is the fact that Caesar praises someone, especially a person that he does not particularly like, which is important. At the end of scene four, Lepidus and Caesar are talking about getting more information about what is going on in the world, giving the current problems that t they are having: Lepidus: What you shall know meantime  Of stirs abroad, I shall beseech you, sir,  To let me be partaker.  Caesar: Doubt not, sir, I knew it for my bond.  (I.iv.83b-86)  This short dialogue, containing some quite harsh-sounding phrases for people are that are meant to be friends, shows that there might be a small rift growing between these two men, in addition to the disagreements between Antony and Caesar. Lepidus asking for information about what is going on, from Caesar shows that there might be an issue of a lack of trust developing, whilst Caesar’s rebuttal of â€Å"doubt not, sir, I knew it for my bond,† shows that Caesar could be losing patience with Lepidus, who is always portrayed as being quite a weak and unimportant character anyway.

Early American Aircraft Development and World War I

While human warfare dates back to at least the 15th Century when the Battle of Megiddo  (15th century BC) was fought between Egyptian forces and a group of Canaanite vassal states led by the king of  Kadesh, air combat is barely more than a century old.  The Wright brothers made the first flight in history in 1903 and in 1911 aircraft were first used for warfare by Italy using planes to bomb Libyan tribesmen.  In World War I, aerial warfare would play a major for both sides with dogfights first taking place in 1914 and by 1918 the British and German were making widespread use of bombers to attacking each others cities. By the end of World War I, more than 65,000 airplanes had been built. The Wright Brothers at Kitty Hawk On December 17, 1903, Orville and Wilbur Wright piloted first powered airplane flights in history over the windy beaches of Kitty Hawk, North Carolina.  The Wright brothers made four flights that day; with Orville taking the first flight that lasted a mere twelve seconds and traversed 120 feet.  Wilbur piloted the longest flight which covered 852 feet and lasted 59 seconds.  They choose Kitty Hawk due to the constant winds of the Outer Banks that helped to lift their aircraft off the ground. Aeronautical Division Created On August 1, 1907, the United States established the Aeronautical Division of the Office of the Chief Signal Caller.  This group was placed in â€Å"charge of all matters pertaining to military ballooning, air machines, and all kindred subjects.† The  Wright brothers  made the initial test flights in August 1908 of what they hoped would become the Armys first airplane, the Wright Flyer. This had been built to military specifications.  In order to be awarded a military contract for their aircraft, the Wright brothers had to prove that their planes were able to carry passengers. First Military Casualty   On September 8 and 10, 1908, Orville conducted exhibition flights and carried two different Army officers for a plane ride.  On September 17th Orville made his third flight carrying Lieutenant Thomas E. Selfridge, who became the very first U.S. military personnel to be a casualty from an airplane crash. In front of a crowd of 2,000 spectators, Lt. Selfridge was flying with Orville Wright when the right propeller broke causing the craft to lose thrust and go into a nosedive. Orville turned off the engine and was able to an altitude of about 75 feet, but the Flyer still hit the ground nose-first. Both Orville and Selfridge were thrown forward with Selfridge striking a wooden upright of the framework causing a fractured skull which led to his death a few hours later. In addition, Orville suffered several severe injuries which included a broken left thigh, several broken ribs, and a damaged hip. Orville spent seven weeks in a hospital recuperating. While Wright was wearing a cap, Selfridge was not wearing any headgear but had Selfridge had been wearing any type of helmet, he more than likely would have survived the crash. Due to Selfridges death, the U.S. Army required their early pilots to wear heavy headgear which was reminiscent of football helmets from that era. On August 2, 1909, the Army chose a revamped Wright Flyer which had undergone much more testing as the first powered fixed-wing aircraft.  On May 26, 1909, Lieutenants Frank P. Lahm and Benjamin D. Foulois had become the first U.S. serviceman to qualify as Army pilots.   Aero Squadron Formed The 1st Aero Squadron, also known as the 1st Reconnaissance Squadron, was formed on March 5, 1913, and it remains as America’s oldest flying unit.  President William Taft ordered the unit organized due to increasing tensions between the U.S. and Mexico.  At its’ origin, the 1st Squadron had 9 airplanes with 6 pilots and approximately 50 enlisted men. On March 19, 1916, General John J. Pershing ordered the 1st Aero Squadron to report to Mexico and therefore the first U.S. aviation unit to participate in military action.  On April 7, 1916, Lt. Foulois became the very first American pilot to be captured even though he was only held for a day. Their experience in Mexico taught both the Army and the U.S. Government a very valuable lesson. The Squadron’s main weakness was that it had too few airplanes to properly conduct a military operation.  World War I was teaching the importance of each squadron having 36 total airplanes: 12 operational, 12 for replacements, and 12 more in reserve of 12. The 1st Aero Squadron consisted of only 8 airplanes with minimal spare parts. In April 1916 with only 2 airplanes in the flyable condition in the 1st Aero Squadron, the Army requested a $500,000 appropriation from Congress to purchase 12 new airplanes – the Curtiss R-2’s that were equipped with Lewis guns, automatic cameras, bombs, and radios After much delay, the Army did receive 12 Curtiss R-2s but they were practical for the Mexican climate and required alterations which took until August 22, 1916, to get 6 planes into the air. As a result of their mission, the 1st Squadron was able to General Pershing with the first aerial review conducted by a U.S. air unit. US Aircraft in World War I When the United States entered World War I on April 6, 1917, the countries aircraft industry was mediocre in comparison to Great Britain, Germany, and France, each of which had been involved in the war from the onset and had learned firsthand about the strengths and weaknesses of combat-ready aircraft.  This was true even though there had been more than ample funding provided by the U.S. Congress around the start of the war.   On July 18, 1914, the U.S. Congress replaced the Aeronautical Division with the Aviation Section of the Signal Corps.  In 1918, the Aviation Section then became the  Army Air Service.  It would not be until September 18, 1947, that the United States Air Force was formed as a separate branch of the U.S. military  under the National Security Act of  1947. Although the U.S. never reached the same degree of aviation production experienced by their European counter-parts countries during World War I, starting in 1920 numerous changes were made that resulted in the Air Force becoming a major military organization in time to help the United States prevail in World War II.

Enron s Ceo Jeff Skilling Essay - 1025 Words

Enron executives Ken Lay and Jeffrey Skilling were found guilty of fraud and conspiracy. Andrew Fastow, Enron’s CFO, cut a deal in a plea-bargain in which he testified against his former bosses. The three of them have been called sociopaths. For instance, when Skilling took the stand he almost seemed humble, and assured his innocence, claiming that Enron didn’t do anything wrong.

Hydrogen bomb=fission ignites secondary reaction that contains two isotopes of hydrogen-most dangerous part of residual radioactivity. Nuclear reactors are based the chain reaction but normally work with neutron multiplication of 1 o reaction doesn’t grow. Moderators slow neutrons so they are more likely to attract to nucleus. If moderator is lost the chain reaction stops. If it runs away and c. r. begins to grow exponentially, the slowness of the neutrons limits the size of the explosion. Since a c. r. depends on slow neutronsa cr that depends on slow neutrons cannot give rise to a nuclear explosion so therefore a reactor cannot blow up like a bomb b/c when temp increases, aroms are moving too fast for the neutrons to hit them so the c. stops.

Satellite in low earth orbit=5 mi/sec . high sat=slow. Geosynchrous sat= sat that orbites in 24 hours. . blackhole=escape velocity = faster than speed of light. Big mass or lots packed into small radius . rockets fly by pushing burned fuel down. /c rocket weighs so much more fuel, the amount of velocity gained by rocket is much less than the fuel velocity so very inefficient. Gravity=attraction between two masses. Radioactivity= explosion of nucleus atom. Radiation=pieces thrown out in explosion.. chernyobyl-vessel explosded in Ukraine, radiation went all the way to stockhom. Don’t know if deaths were from radiation or regular cancer. Firefighters died from radiation45 rem receved average.. 25 rem=1% cancer chance. The hydrogen economy is a proposed system of delivering energy using hydrogen. Thinks methane is the way since ch4. he term â€Å"hydrogen economy† describes an envisioned large-scale scheme of delivering energy by means of hydrogen, particularly for â€Å"motive power† (personal cars, buses, planes, ships, etc. ). This is attractive for several reasons, among them the clean way in which hydrogen burns (it only leaves water as a residue), its high energy per weight, and the fact that fuel cells can convert hydrogen’s energy directly into electricity that subsequently powers an electric motor, with a combined efficiency exceeding that of ordinary combustion engines. Around 4:00 am on the morning of March 28, 1979, water pumps in the non-nuclear section of Three Mile Islands’ Unit 2 nuclear power plant stopped working. This prevented the steam generators from removing heat from the plant and initiated an automatic shutdown of the reactor. The possiblity that the melting of fuel rods could result in a release of radioactivity to the surroundings was of great concern. The Nuclear Regulatory Commission was alerted at 8:00 am and the White House was alerted at 9:15 am. By 11:00 am, all non-essential personnel were evacuated from the facility. The remaining personnel worked to bring the situation under control over the next several days. According to the U. S. Nuclear Regulatory Commission, this accident, â€Å"was the most serious in U. S. com- mercial power plant operating history, even though it led to no deaths or injuries to plant workers or members of the nearby community. But it brought sweeping changes involving emergency response plan- ning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. † – melted cre How to cite Physics for Future Presidents Notes-Final Exam, Essay examples
