Leukemia Research Paper Essay Example for Free

Leukemia Research Paper Essay PART I: I personally know of a couple of skeletal diseases. I know of Leukemia, which is a type of cancer where white blood cells multiply in an uncontrolled manner, and the cause is unknown. I have also personally met someone with Leukemia, and it is not a slow-moving disease; he unfortunately died within a few years. I know of osteoporosis from the notes. It is a disease resulting in the loss of bone tissue. The cancellous bone loses calcium, becomes thinner, and may eventually disappear altogether. I don’t know if a fracture constitutes as a bone disease, but they can be Spiral, Closed, Open, or Multiple. One of the most well-known bone diseases is Arthritis. It is a disease of the joints; victims suffer pain, stiffness, and swelling of the joints. Many athletes will also show signs of Tendonitis, a disorder involving stiffness or pain in the muscles or joints. I want to find out more about Leukemia, the most relatable disease to me, and what symptoms the victims of it suffer. PART II: I am going to choose to research the skeletal disease of Leukemia, because it has personally affected me in my life. One of our close family friend’s children died of Leukemia when he was five. He had a very advanced form of Leukemia when he was born and it was a very sad time when he passed. I will more specifically be researching Juvenile Myelomonocytic Leukemia, the disease he suffered from. I am looking for treatment options, symptoms, and prevention abilities. PART III: I began my search by typing â€Å"Leukemia† into Google search and got many reliable sources. I chose a source from the Mayo Clinic that clearly defined the disease and had a brief synopsis of the disease. I also went to the Leukemia Lymphoma society’s website and found a document on the specific type of leukemia I was researching. I also searched the symptoms of Leukemia and found a good source on Medicine Net. SOURCES: http://www.lls.org/#/diseaseinformation/leukemia/jmml/ http://www.mayoclinic.com/health/leukemia/DS00351 http://www.medicinenet.com/leukemia/page5.htm#symptoms PART IV: I learned that Leukemia is a blood cancer that attacks the bone marrow and the Lymphatic system. I learned that many different types exist and treatment can be complex, depending on the type of Leukemia and other factors. I learned that Juvenile Myelomonocytic Leukemia is most commonly diagnosed in infants, much like my close friend. I didn’t know, but JMML is a very uncommon type of blood cancer and it only occurs in infancy and early childhood. I learned that symptoms can be fevers, frequent infections, swollen lymph nodes, weight loss for no reason, bleeding and bruising easily, and pain in the joints and bones. I learned that doctors diagnose Leukemia by physical exams as well as blood tests and biopsies. I learned that stem-cell transplantation could be used for treatment of this cancer. My friend had this done with the help of his younger brother, and actually went into remission for two years. I really learned a lot about this disease and have an enlightened perspective on Leukemia and its unfortunate victims.

The Adventure of the Speckled Band by Sir Arthur Conan-Doyle (1892), :: English Literature

The Adventure of the Speckled Band by Sir Arthur Conan-Doyle (1892), The Ostler by Wilkie Collins (1855), and The Signalman by Charles Dickens (1864). All of these are mystery stories How do the writers try to create excitement, mystery and suspense? Which of the stories you have read was the most successful and why? I have chosen to write about three stories – ‘The Adventure of the Speckled Band’ by Sir Arthur Conan-Doyle (1892), ‘The Ostler’ by Wilkie Collins (1855), and ‘The Signalman’ by Charles Dickens (1864). All of these are mystery stories that have been written in a similar way, with classic ‘mystery and suspense’ techniques. These stories were all written in the nineteenth century, and reflect this period with the use of old language and settings. Also the use of horses & carriage and the disadvantage of there being no electricity. Many archaisms are used in all three of the stories and these reflect the period. Nobody would use such language today, which also helps to draw the reader into the story because the reader has to concentrate on the complicated language and long sentences. The narrative structure in ‘The Signalman’ and ‘The Ostler’ is very similar, with both narrators reliving the stories and telling them to the reader, where as, in the ‘Speckled Band’, the reader seems to be being told the story as it happens. In the ‘Speckled Band’ even though he is speaking from a time after the events of the story Dr Watson tells us the story as it happens so you feel included, as though you are there in the story with the characters. This also makes the story seem more believable – factual rather than fictional – that it actually happened and that Dr Watson was there. This allows us to share his thoughts and feelings to further include us in the story. For example ‘I find many tragic, some comic, a large number merely strange.’ This shows us Dr Watson’s feelings. Sherlock Holmes is one of the main characters in this story and he is very well known for his success as a detective. He is visited by a young woman (Helen Stoner), who needs his help after the very sudden and unexplained death of her sister, as she is worried for her own safety. This character actually narrates the first part of the story (after Watson’s introduction), while she tells Sherlock Holmes of the unsolved mystery. Her story is told in first person narrative so the reader relives the time when her sister dies. Pathetic fallacy is again used to create an ideal setting for a murder.

How Has Computer Hacking Interfered Modern Society Essay

How has computing machine choping inferred modern society? In this transition I will be speaking briefly about the basicss of computing machine choping from the yesteryear to the present. Computer hacking has changed more over clip ensuing in computing machine outgrowths to corporate system closures. This research paper will be speaking about three major parts of computing machine hacking. The first construct of hacking is the beginning of creative activity. The following portion will be how hacking has affect on the contemporary society. Finally. the last piece of information will be traveling over the hereafter of system choping. What is a drudge you may inquire your ego but non hold an reply or one word phrase for the term? A drudge has ever been a sort of cutoff or alteration. a manner to short-circuit or make over the standard operation of an object or system. The first computing machine hackers emerge at MIT. They borrow their name from a term to depict members of a theoretical account train group at the school who hack the electric trains. paths. and switches to do them execute faster and otherwise. A few of the members transfer their wonder and set uping accomplishments to the new mainframe calculating systems being studied and developed on campus. Choping groups begin to organize. Among the first are Legion of Doom in the United States. and Chaos Computer Club in Germany. The film â€Å"War Games† introduces the populace to choping. A computing machine hacker intends to destroy concerns executing an act much more unprincipled than an enthusiastic life scientist ‘hacking’ off at work or theory. The truth is that computing machine hacking is in fact easy in the general sense. but more consideration must be given. Some facets of choping are used in mundane life and you may non cognize that accessing wireless cyberspace from another person’s history is considered wireless choping even though your adoption there connexion. During the 1970’s. a different sort of hacker appeared: the phreaks or phone hackers. They learned ways to chop the telephonic system and do phone calls for free. Within these group of people. a phreaker became celebrated because a simple find. John Draper. besides known as Captain Crunch. found that he could do long distance calls with a whistling. He built a blue box that could make this and the Esquire magazine published an article on how to construct them. Fascinated by this find. two childs. Steve Wozniak and Steve Jobs. decided to sell these bluish boxes. get downing a concern friendly relationship which resulted in the initiation of Apple. By the 1980’s. phreaks started to migrate to computing machines. and the first Bulletin Board Systems ( BBS ) appeared. BBS are like the yokel groups of today. were people posted messages on any sort of subject. The BBS used by hackers specialized in tips on how to interrupt into computing machines. how to utilize stolen recognition card Numberss and portion stolen computing machine watchwords. It wasn’t until 1986 that the U. S. authorities realized the danger that hackers represented to the national security. As a manner to antagonize this threat. the Congress passed the Computer Fraud and Abuse Act. doing computing machine interrupting a offense across the state. During the 1990’s. when the usage of the cyberspace became widespread around the universe. hackers multiplied. but it wasn’t until the terminal of the decennary that system’s security became mainstream among the populace. Today. we are accustomed to hackers. crackers. viruses. Trojans. worms and all of the techniques we need to follow to battle them. Hackers were classified into three unusual types the first class is called In-house hacker. In-house hacker is an employee who is responsible for operating and keeping the system. who interacts instantly with the system as a coder or informations entry employee and is cognizant of all the system security capablenesss and spreads. He and should be the guard of the system but for different motives he hacks the system and gets what he needs bewraying all the trust given to him. The 2nd type is called ace hacker who doesn’t interact with the system but at the same clip proctors the system on day-to-day footing and has an oculus on what is traveling on and what type of informations is entered at what clip so depending on the entries he decides the minute he should acquire these information and recover them for personal motives while the 3rd type is called professional hacker and this hacker is really strong and capable of acquiring any type of informations. he has the ability of carrying the user or the operator to supply him with the needed information by programming fast ones or user friendly screens and this sort of hackers frequently gets alone preparation specially when being used in military undertakings as what happened in the cold war. Thesiss are merely brief ways hackers have impacted the modern universe we all live in. Within the past twelvemonth at that place have been two major instances right in the country. Both involve extended harm. and both are presently in tribunal. The closest instance is that of Thomas Crandall. otherwise known as St. Elmo’s Fire. Crandall is accused of estroying attending and subject records in a computing machine at Central Technical and Vocational Center. Police charge that Crandall used a personal computing machine at his place to entree the computing machine. He is besides accused of making $ 25. 000 in harm to files at Waste Management Inc. of Oakbrook. Ill. Crandall’s lawyer claims that many other pupils besides had entree to the computing machine. and that to individual out Crandall in unjust. Hackers are responsible of the immense development in computing machine and cyberspace engineering. but these yearss we consider them as stealers and interlopers who penetra ted our ain privateness and used the accomplishments they were buttockss for their ain benefit. Hackers have different sentiments and motives. However. they all portion the spirit of challenge and ever seeking to turn out their capablenesss of making what all believe is impossible possibly because they were mistreated. or uncertainties surrounded their abilities and past accomplishments. Hackers believe that information should be shared and they fight against information owning. Effectss that choping caused and still doing to the society can’t be ignored. Hacking nowadays is taking new stages and the danger is increasing because we are now populating in a society that runs by ICT. and any onslaught to the ICT particularly in advanced states will do critical effects. ICT still lacks a powerful security tools that are capable of tracking. catching hackers. and protecting computing machine systems from their onslaughts. My ain position is that the best manner to protect ICT from hackers is to analyze their psychological science and seek to understand their manner of thought. because hackers are human existences. who have two sides ; evil and good. and they used to demo their good side but all of a sudden they turned to be evil. The grounds which caused the transmutation from good to evil persons should be studied and given the highest precedence in the war against hackers because since we put our custodies on the cause. we can repair it to make for better effects. Peoples can grocery store. earn grades. receive bank statements and pay measures from their laptop or Personal computer. The possibilities are endless when it comes to simplifying life with the aid of the World Wide Web. but at the same clip possibilities are eternal hackers to perplex your life with cyber offenses. The Merriam-Webster Dictionary defines a hacker as both â€Å"an expert at programming and work outing jobs with a computer† and â€Å"a individual who illicitly additions entree to and sometimes tamping bars with information in a computing machine system. † Those three grounds I have stated above were the hackings past present and future. Until engineering Michigans turning the possibility of hackers is limited less.

Heavy Metal Definition and List

A heavy metal is a dense metal that is (usually) toxic at low concentrations. Although the phrase heavy metal is common, there is no standard definition assigning metals as heavy metals.   Characteristics of Heavy Metals Some lighter metals and metalloids are toxic and, thus, are termed heavy metals though some heavy metals, such as gold, typically are not toxic. ​ Most heavy metals have a high atomic number, atomic weight and a specific gravity greater than 5.0 Heavy metals include some metalloids, transition metals, basic metals, lanthanides,  and actinides. Although some metals meet certain criteria and not others, most would agree the elements mercury, bismuth, and lead are toxic metals with sufficiently high density. Examples of heavy metals include lead, mercury, cadmium, sometimes chromium. Less commonly, metals including iron, copper, zinc, aluminum, beryllium, cobalt, manganese and arsenic may be considered heavy metals. List of Heavy Metals If you go by the definition of a heavy metal as a metallic element with a density greater than 5, then the list of heavy metals is: TitaniumVanadiumChromiumManganeseIronCobaltNickelCopperZincGalliumGermaniumArsenicZirconiumNiobiumMolybdenumTechnetiumRutheniumRhodiumPalladiumSilverCadmiumIndiumTinTelluriumLutetiumHafniumTantalumTungstenRheniumOsmiumIridiumPlatinumGoldMercuryThalliumLeadBismuthPoloniumAstatineLanthanumCeriumPraseodymiumNeodymiumPromethiumSamariumEuropiumGadoliniumTerbiumDysprosiumHolmiumErbiumThuliumYtterbiumActiniumThoriumProtactiniumUraniumNeptuniumPlutoniumAmericiumCuriumBerkeliumCaliforniumEinsteiniumFermiumNobeliumRadiumLawrenciumRutherfordiumDubniumSeaborgiumBohriumHassiumMeitneriumDarmstadtiumRoentgeniumCoperniciumElements 113-118 Keep in mind, this list includes both natural and synthetic elements, as well as elements that are heavy, but necessary for animal and plant nutrition.
