How Cell Phones Can Cause Cancer for Users Research Paper

How Cell Phones Can Cause Cancer for Users - Research Paper Example Cell phones are examples of gadgets that emit radiofrequency energy. This paper, in effect, explains how cell phones cause cancer to their users. Radiofrequency Radiation and Cell Phone Use Radiofrequency (RF) is a type of electrical energy found between 300 kilohertz (KHz) and 1 megahertz (MHz) frequency ranges. Weinberg (p. 17) observes that â€Å"†¦RF penetrates human body and is absorbed by deep body organs without feeling of any heat sensation.† Weinberg (p. 17) deduces that it this property of radiofrequency energy that makes cell phones harmful to their users. The gadgets play a major role in development of brain cancers because the antenna which absorbs and emits signals transmits the same radiation to the brain of a user. Several studies confirm a strong correlation between use of cell phones and brain cancer. (Schuz et al.1707). Causes of neck cancer and cancers of various nerves in the head have also been attributed to cell phone use. Mechanism used by microwav e ovens to heat food is analogous to how RF energy emitted by cell phones behaves. However, heat produced by RF exposure from cell phones is not sufficient enough to significantly increase body temperature. Muscat et al. (p. 3001) explains that using a cell phone while holding it on one side of the head affects brain tissues close to antennae of the phone. Radiofrequency energy emitted from the cell phone increases glycolytic process (breakdown of glucose to pyruvate with release of energy) in these tissues. Slight increase in temperature in these tissues triggers faster metabolism of glucose than in tissues opposite to antennae of the cell phone. Uneven rate of glycolysis in the brain results to imbalance energy distribution in brain tissues. Unequal distribution of energy in the brain promotes unequal cell growth in brain tissues resulting to uncontrolled and imbalanced cell division and growth of brain tissues. Brain tumors are products of uncontrolled cell growth and division of cells in the brain tissues. The tumors grow rapidly and form enlarged cell masses than surrounding cells. Surplus energy on one side of the head can, thus, cause brain tumors on one side of the brain. RF radiations produce malignant tumors. The tumors are non-encapsulated cells that grow quickly and readily metastasize into surrounding cells. Metastasis is the ability of a tumor cell to break from the tumor and freely enter the bloodstream (Larjavaara et al. 4). Tumor cells can, therefore, travel to other parts of the body and begin to rapidly divide and grow. More often, malignant tumor cells are characterized by anaplasia, a condition in which a cell loses its distinctive features. Larjavaara et al. (p. 10) concludes that cancer is a result of cell reversion. Consequently, cell phone users not only expose themselves to brain cancer, but also increase their chances of developing cancer of other body organs. According to Larjavaara et al. (p. 2), common brain cancers caused by radi ations emitted from cell phones include glioma and neuroma brain cancers. Glioma is a spinal cord or a brain tumor made up of neuroglia, a connective tissue of the nervous system. Glioma tumors arise from abnormal glial cells in the brain. Immediate symptoms of gliomas, which are not as deadly as glioma cancer, include nausea, vomiting, headaches, and cranial nerve disorders among others. Neuroma brain cancer, on the other hand, is a cancerous tumor that

Bus 303 Practice Midterm Essay Characters: Cathy and Dave, a well-to-do professional couple Al, a real estate salesman Cathy and Dave are young, upwardly mobile. They hold good professional jobs in downtown Chicago. One day Cathy received an invitation in-the mail, from a resort called Green Acres (GA), which was located near the mountains, about eight hour driving time from Chicago. The mailer invited the young couple to spend two nights free of cost and receive $50 for expenses. All they had to do in return was to listen to a presentation, see a video, and take a tour of the resort for about two hours. Additional conditions included 24 hour advance booking of the room with 24 hour notice for cancellations, and a valid credit card. Green Acres would charge $50 for a no show. Although the letter made no mention of it, Cathy and Dave knew the invitation was a real estate promotion and guessed that the two hours with the GA staff meant a hard sell for a condo or a timeshare near a lake or a golf course, something they did not want. They decided to take the offer anyway in order to get a free vacation and arranged to visit GA the following weekend. Cathy and Dave had a good time at GA. The only sour point of the trip was the last exchange they had with Al the salesman. At the end of the two hour presentation when Cathy and Dave had refused to buy any GA properties, Al looked at Dave in frustration and said, â€Å"If you knew you weren’t going to buy any property here, why did you come? Our company spent $300 to get you down here, and you have taken food off my family’s table. What you did is immoral. Please don’t do it again. At this Dave retorted, â€Å"Your letter was clear, there was nothing in it that said a purchase of real estate was involved, and we had no obligation to buy anything from you. Your invitation was unconditional, I don’t owe you or your family anything and I resent what you just said.† At the end of this uncomfortable exchange, Cathy and Dave left the room with an unpleasant feeling. But the unpleasant feelings did not last long because the drive back through the mountain s was truly spectacular. After a few days Cathy said to Dave, â€Å"You know, Im still mad about what Al said to us at Green Acres. Should we write to his boss, or to the real estate board or to some government agency? You know, if we don’t do something, some poor unsuspecting people might fall for their gimmicks!† Dave replied, â€Å"No, I dont think we should waste any time on this. Most people know, or should know what they are getting into-there are no free lunches! Besides if we complain, Al may lose his job and when we’ll be really taking the food from his family’s table!† What Are the Relevant Facts? 1. Cathy and Dave are educated and well paid. 2. They received an unsolicited invitation from Green Acres (GA). 3. The invitation had nothing in it that said they had to buy anything from GA. 4. They correctly guessed that the GA sales staff would put pressure on them to buy real estate. 5. GA was eight hours driving time from Chicago. 6. Al made a sales presentation. 7. Cathy and Dave listened to the presentation. 8. Al said Cathy and Dave had acted immorally and had deprived him of a chance of earning a sales commission. 9. Dave said that they had fulfilled their obligation, as outlined in the invitation, and had not acted incorrectly. What Are the Ethical Issues? 1. What is the role of inducements in marketing? 2. What is the responsibility of individuals who accept inducements? Do they have any moral obligations to purchase goods if they accept free gifts from merchants? 3. Is giving attractive gifts to potential buyers an ethical practice? Does the size of the gift or the inducement matter? 4. Cathy and Dave were sophisticated, educated city folk and did not feel pressured to buy from GA. Do less educated or less sophisticated consumers feel pressured to buy merchandise under enticements of gifts? Would such business practice be considered ethical? 5. Should Cathy and Dave complain so that other vulnerable people may not be pressured into buying expensive property they do not want? Who Are the Primary Stakeholders? †¢ Cathy and Dave †¢ Al †¢ GA †¢ GA’s stockholders †¢ Other potential consumers, especially the vulnerable ones What Are the Possible Alternatives? 1. Cathy and Dave can forget the incident and do nothing. 2. They can file a complaint with GA. 3. They can file a complaint with the appropriate authorities. 4. They can write to Al. What Are the Ethics of the Alternatives? 1. What is the best course of action for Cathy and Dave from the moral standpoint? What is the best course of action that Cathy and Dave take that will provide the greatest benefit to the greatest number? 2. Do Cathy and Dave and other potential customers have rights not to be pressured or induced into actions they may not wish to take? Do GA and Al have rights to pursue their business and personal interests? Were any rights violated? 3. What is the just thing to do in this case? Which alternative distributes the burdens and responsibilities fairly? If Cathy and Dave act and if GA improves its practices everyone except Al may benefit. Not complaining may mean Al will continue his tactics and undermine GA’s goals assuming that word would get around and additional customers will be offended. What Are the Practical Constraints? None. What Actions Should Be Taken? 1. What should Cathy and Dave do? 2. Which alternative would you choose? 3. Which approach (utilitarian, rights, or justice) makes the most sense to you in this situation? Clearly, no action could mean unsuspecting people may be lured into buying expensive real estate with potentially severe consequences. Complaints could lead to improved practice and better performance but could lead to the loss of Al’s job. 4. What is the right thing to do?

Revenge and Vengeance in Shakespeares Hamlet - Going Beyond Revenge Es

Going Beyond Revenge in Hamlet      Ã‚  Ã‚  Ã‚  Ã‚  The simplest and superficially the most appealing way to understand Shakespeare’s Hamlet is to see it as a revenge tragedy. This genre was well established and quite popular in Shakespeare’s time, but it was precisely part of his genius that he could take old forms and renew them by a creative violation of their standards. As this essay will explore, Hamlet stands the conventional revenge tragedy on its head, and uses the tensions created by this reversal of type to add depth to its characters and story.      Ã‚  Ã‚  Ã‚  Ã‚   The revenge tragedy of Shakespeare’s age, as exemplified in such productions as The Spanish Tragedy by Thomas Kyd and The Tragedy of Hoffman by Henry Chettle was gruesome to a degree. In the latter work, for instance, the hero displays on stage the skeleton of his father, who has been tortured to death for piracy, and later on takes part of his revenge by killing one of his enemies with precisely the same tortures, and hanging him in chains beside the skeleton of his father. In the process, the original religious symbolism of death imagery, in particular the skeleton and the skull, is perverted into little more than eye-catching tokens of revenge (Jacobs 1993).      Ã‚  Ã‚  Ã‚  Ã‚   The classic revenge tragedy is thus quite a simple affair: there is an offence, and it is followed in a fairly mechanical manner by revenge, preferably bloody and protracted. However, as Delville and Michel (1998) point out, this structure is undermined by Shakespeare in the person of Hamlet. Unlike even Shakespeare’s own creations, Brutus, Macbeth, and Othello, Hamlet is unpredictable. In an earlier version of the play, referred to as the Ur-Hamlet, and attributed to Thomas Kyd, the only reason for... ...rd and poisoned cup. In the deaths of Polonius and Ophelia, and indeed in his own, he learns that means cannot be separated from ends, and that the consequences of his own choice of means – his madness – will come back to haunt him. It is in this sense that Hamlet may be read as a journey of self-discovery, even though the journey ends only in the grave.    Works Cited Delville, Michel and Pierre Michel. â€Å"Introduction to Hamlet.† Tr.

Playing Beatie Bow Essay

What does Abigail learn about the importance of the family? Discuss how Ruth Park represents her characters and ideas about the family using (3) novel and language techniques In the novel Playing Beatie Bow by Ruth Park, the protagonist Abigail learns about the importance of the family. She is a headstrong fourteen-year old girl who has had troubles in her own family, but when she is transported to the Rocks, 1873, and meets the Bow family, she realizes her selfish ways. From her experiences with them Abigail learns that in any situation every family member, including herself, must demonstrate the key elements of keeping a family together. These include love, forgiveness, support and understanding. Ruth Park uses many techniques that illustrate the main theme of the novel – how Abigail learns about the importance of the family. In Playing Beatie Bow Abigail learns that love and forgiveness are vital elements in keeping a family together. Abigail is an unforgiving child, especially towards her divorced parents. To Abigail, â€Å"her father was a king† and the metaphor emphasizes how much she adores him. However when her father â€Å"went off with another lady†, Abigail is so outraged that she hits him and refuses to forgive him. Abigail’s unloving attitude was causing the family to fall apart, and she realizes this with â€Å"sickish surprise† when she meets the Bow family in 1873. Gibbie Bow is an ill boy; a â€Å"self-important little monster† to Abigail. The metaphor emphasizes Abigail’s dislike for â€Å"unlovable and obnoxious† Gibbie, so when she realizes â€Å"Dovey’s devotion to the child, her sleepless nights and endless patience†, she is hit with â€Å"embarrassed astonishment†. The continuous descriptive language emphasizes the shock Abigail feels when she recalls her own attitude towards her family compared to the loving and forgiving Bows. When she returns to her own time, Abigail forgives her parents and realizes how much she loves them. She displays love and forgiveness which she has learnt from her experiences with the Bows. Another lesson Abigail learns about the importance of the family is that families support each other in hard times. The Rocks in 1873 is a dangerous world where many die from diseases or war. Abigail’s time is â€Å"paradise compared with Beatie’s own time†, and the metaphor emphasizes how harsh the living conditions of 1873 are. The Bowsâ€℠¢ mother passed away Dovey, still a young lady, devotes herself to the Bows and Abigail as if she were a mother. Mr. Bow suffers mental issues due memories of his wife’s death and when he drinks alcohol and goes mad he  says: â€Å"I dunno if I’m on head or heels†. The author includes the Scottish idiom to emphasize the Bows’ unsophisticated language as well as the helplessness of Mr. Bow. He cannot play his role as a father properly, so at fourteen years old Judah begins to earn money as a sailor, looking after the family like a father. The Bows and even Abigail rely on him and seem to â€Å"absorb vitality from him†. Park has used the metaphor to show how trustworthy and supportive Judah is. Abigail learns from and even joins in with the Bows as they support each other in this cruel world, each playing their role to keep the family together. Abigail learns the importance of understanding in a family from her experiences with the Bow family. Whe n her father leaves, Abigail is too â€Å"wrapped up† in her own problems to comfort her mother even though Kathy was just as troubled. The author uses the metaphor to accentuate Abigail’s inconsideration towards others’ feelings. The â€Å"precious† Gift is an ability only Bows own, and as Abigail has a role in preserving it, she is kept from escaping 1873. At first she believes it is â€Å"absolutely repulsive† and refuses to stay, but as she feels closer to the family she begins to understand the importance of the Gift to the Bows. Later Abigail plays her role by saving Gibbie and Dovey from â€Å"bluish tongues of flame† in a fire. The use of personification of the flames emphasizes the frightening experience of the fire and Abigail’s will to risk her life to save Gibbie. By having to accept her role with the Gift, Abigail learns about understanding and being unselfish towards her family. In Playing Beatie Bow, Ruth Park illustrates the lessons Abigail learns about the importance of the family. Although she was selfish and unforgiving at the beginning of the novel, through her experiences with the Bows Abigail learns to display the key elements in keeping a family together. She learns how to love, forgive, support and understand her family, and this allowed her to mature and realize the importance of a family.

Audience is Everything

Audience is Everything Audience is Everything Audience is Everything By Sharon Just as real estate revolves around the old adage, Location! Location! Location!, students, teachers, authors and any writer worth his or her salt lives by a motto as well. Quite simply, audience is everything. Audience dictates all of the elements that go into a successful piece of writing. For instance, one would generally write very differently when addressing a teacher or employer in a formal piece of writing than one would when informally addressing a friend, family member or classmate. For example, after missing a day of work, if you left a message for your boss, it might read: Dear Mr. Smith, I’m very sorry that I was absent from work yesterday, but I fell ill on Tuesday evening and felt it necessary to visit my doctor in an effort to make it back to the office today. In contrast, when writing a note to a friend or co-worker about the same situation, you might say: Carla, Sorry I missed ya yesterday. I got really sick the other night and had to go to the doctor. I’d hate to miss another day of work. The audience that will read your writing dictates the words you choose, the formality of your work and the tone of your writing â€Å"voice.† Writing that requires formality generally sounds proper and practiced while informal writing often comes across as conversational. Always keep in mind the appropriateness of your writing and the way your writing voice might sound to an objective reader when you put words to paper.

When to See a Doctor for Bursitis

When to See a Doctor for Bursitis Bursitis is defined as the irritation or inflammation of a bursa (fluid-filled sacs attached to joints). You can often effectively treat bursitis at home. However, in some cases, you may want or need to treat bursitis with some techniques not available at home and require a visit to a doctor. If you have bursitis and you experience a warm swelling, a fever or become sick you may have septic bursitis and should seek medical attention. Septic bursitis needs antibiotic medication to treat it. In the case of non-septic bursitis you should consider seeing a doctor: If the pain becomes severe or is getting progressively worseIf your range of motion is being hampered and the swelling and stiffness is getting worseIf your strength is affectedIf the injury is becoming chronic and never fully alleviates, or commonly reoccursIf methods for preventing bursitis have not proven sufficientIf home treatments are not effectiveIf you can not change your habits or the repetitive stress causing your bursitis is unavoidable What to Expect From Your Doctor If you are seeking medical help for your bursitis then your general practitioner is probably your first stop. Your doctor will need a history of your condition including the symptoms and activities that trigger or worsen the symptoms. Additionally, you should provide your doctor with information about any treatments, over the counter medication or home remedies you have tried and how effective they have been. Your doctor will perform a basic physical examination of the affected area to check for a swollen bursa. Diagnostic imagery is usually not required  but is some difficult cases it may be requested. Imagery, such as an X-ray or MRI, can help fill out a comprehensive diagnosis. Once diagnosed your doctor may prescribe treatment or refer you to a specialist. In some cases, your doctor may suggest draining the bursa to reduce the swelling. This can usually be done during the same visit. Your doctor will simply insert a syringe into the bursa and remove some of the fluid. This can provide immediate relief but does not treat the cause of bursitis.​ When referring you to a specialist your general practitioner will often suggest a physical therapist or occupational therapist. These therapists will develop a treatment regimen of exercise and/or behavioral therapy that should change or remove the repetitive stress that is causing bursitis as well as strengthening the area so it is more robust. What to Bring to Your Doctor Being prepared with a thorough history of your symptoms can help your doctor diagnose your bursitis. Organize your information to help your doctor get through all the pertinent parts in the time usually allotted for an appointment. The information you should have on hand includes: What your symptoms areWhen your symptoms first presented or startedHow severe your symptoms areIf your symptoms come and go or are persistentWhat activities trigger or worsen your symptomsWhat kind of repetitive stress concerning the area of your bursitis you regularly encounterAny candidate causes of bursitis you have identifiedAny injuries within the past 6 months to the area of your bursitisOther medical conditions you currently suffer from or have had in the past, including surgeries When gathering your information, it is beneficial to journal your symptoms. Write down all your symptoms with notes about duration and severity. Use a Visual Analog Pain Scale to track the pain. Make notes of the activities that may contribute to bursitis and what effect they seem to have. Furthermore, write down any treatments and if they have a positive or negative effect. Last, but not least, write down any questions you have for your doctor before your appointment. Patients often get nervous or forget their questions when face to face with their doctor. Write down your questions and make sure you get satisfactory answers before you leave. Dont forget, your doctor is there to help you and you are paying them for that help, so make sure to get your moneys worth.
