Fish Oil-Fed Mice Have Impaired Resistance to Inuenza Infection Article

Fish Oil-Fed Mice Have Impaired Resistance to Inuenza Infection - Article Example The critique and analysis focuses on feeding animal trials which include in vivo problems of the host with a live agent of infection. Pathogen clearance and host survival are the typical end points analyzed in the studies. Data shows that (n-3) PUFA can both impair and improve the resistance of host to a certain pathogens number. Nevertheless, the information is still limited in depth and breadth. For the pathogens with existing data, published studies numbers generally do not surpass three or two. Emphasis is on defining crucial immunological and microbiological difference s in pathogen-host interactions that assist to explain the published findings incongruity. Researchers believe that straight examination of (n-3) PUFA on the infectious disease of human’s resistance is warranted. From the oils of fish, Omega-3 fatty acids are considered inflammation modulators. This is the action mode for their efficiency and effectiveness against illness of modernity. The diseases include arthritis and rheumatoid. However, there is a downside, because inflammation is a section of response by the immune system, fish oil decreases immunity. The other side of inflammation decrease. For instance, mice fed with oil of fish, have impaired opposition to the infection of influenza. In regard to theietary long-chain PUFA derived from fish oil have been shown to have beneficial effects on chronic inflammatory and autoimmune disorders (1,2) and long-chain PUFA such as eicosapentaenoic acid appear to be most beneficial . A number of studies report that the immunosuppressive effects of PUFA are a result of decreased cytokine production and from reductions in T cell proliferation, activation, and signaling Studies of rodents fed fish oil-enriched diets have shown a reduction in natural killer (NK)4 cell activity (8), decreased lymphocyte proliferation (9,10), and decreased antigen presentation functions. In addition, decreases in ex vivo production of

Empires, Product Lines, Stewart Brand and Kevin Kelly Essay

Empires, Product Lines, Stewart Brand and Kevin Kelly - Essay Example What made the British Empire great was the fact that it formed the backbone of industrialization in this world. They were the cornerstone of industrial towns, developed cities and advanced water transport (Black, 2001). Everything the empire’s regime did was stored secretly not wanting any other empire to steal their secrets, which they did extremely well. The Japan Empire The Empire of Japan also known as the Empire of the Rising Sun was both an empire and world power, which existed from the Meiji reinstatement on January 3rd, 1868, to the endorsement of the post-Second World War Charter of Japan on May 3rd, 1947. Colonial Japan's fast militarization and industrialization under the slogan Fukoku Kyohei led to its surfacing as a world power, ultimately culminating in its association in the Axis alliance, as well as the subjugation of a large fraction of the Asia-Pacific expanse. At the summit of its authority, in 1942, the Japanese Empire administered over a land spanning 2,85 7,000 sq mi (7,400,000 square kilometers), which made it one of the leading marine empires in history. The Japan Empire was known mostly for its telecommunication advancement (Black, 2001). The Empire of Japan had a remarkable tally of technological accomplishments, and a remarkably well-equipped military. The army was advanced, but extremely oriental and traditional beyond the rank of other top rated empires. Even though, instead of having bullets, ballistic shells, missiles, warheads and other more straight based weapons, they created hi-tech arms, which armed the Imperial Japanese Forces technical fighting skills needed to defeat any superpower... Empires, Product Lines, Stewart Brand and Kevin Kelly Apple Inc., ever since it started its operation in the 70s, has had a magnificent timeline, which people could consider as a success to the company (Isaacson, 2011). In the 70s, the company produced numerous computing machines such as the Apple I, Apple II, Disk II, which was a driver, and Apple Writer computer software. In the 80s, the firm launched the Apple III computer. It also launched the IB modems, Monitor III, IIA printers, Apple Image writer, Macintosh (128K), AppleColor Composite Monitor and AppleShare Server 1.0. The firm also launched, in the 80s, Macintosh Portable, Apple FDHD SuperDrive and Apple Scanner. In the 90s, the firm launched Macintosh IIfx, Macintosh Classic II, the PowerBook series from 100 to G3, Apple Design Powered Speakers and the Workgroup Server series from 60 to 8550 (Isaacson, 2011). Also, they came up with the Apple Network Server 700/200, eMate 300, Power Macintosh G3 desktop, Power Macintosh G3 minitower, Twentieth Anniversary Macintosh, iMac G3, i Book, iMac (slot loading), Cinema Display (22"), as well as the Power Macintosh G4 Graphite. All these were inventions that took place before the new millennium. They were considered as landmark inventions to such a small established company in the field of IT. However, the 2000s has seen the popularity of Apple Inc. rise to another level. The Big-Kids computing world managed to arbitrate between the numerous computational roles, which could not be reconciled in a more direct manner through making the Apple’s materials a must-have item.

History of the Violin and Bow Essay Example for Free

History of the Violin and Bow Essay Stringed instruments such as the violin and its accompanying variations have been used in music for thousands of years. The first officially recorded use of the violin was during medieval European times. The earliest form of the violin was referred to as a Fiddle and the person playing it was termed as a Fiddler. During the 15th century though, the violins began taking on a new shape and began to carve its own history in music. The evolution of the violin continued into the 16th century when it developed what was to become its final look and shape. It is this artistic representation of a violin that we still recognize and use in our present time. An Italian from Cremona named Andrea Amati, is recognized as the founder of the most famous violin making school. The violin making school is not a structure per se but more of a school of thought and characterization. It was during this time that an explosion in violin making reached as far as Europe even as Cremona remained as the home of the best violin makers in the world. The most famous of these violin making families are the Amati, Guarneri, Antonio Stradivari, Rugerri, and Bergonzi. In the music world, the finest musicians openly acknowledge the Stradivari and Guarneri violins to be the best violins ever made over the past 150 years. The Violin is a member of the string instrument family and is capable of producing a 3 octave sound range when played by skilled musicians. The sound a violin creates depends on a number of factors, the most important of which are the type of wood used to produce the body of the instrument and the type of metal strings used.. It is usually 14 inches in length and uses metal strings tightened to various degrees on tuning pegs, to produce its exceptional sound quality. A typical violin is composed of the following parts: Chin rest, F-hole, strings, tuning pegs, scroll, tailpiece, fine tuners, bridge, belly, fingerboard, neck, and back plate. The sound is produced by the instrumentalists skimming a bow over the metal strings. Violins are usually constructed to withstand the 17 pounds of downward force that is regularly applied to the 4 metal strings. But just like any stringed instrument, the Violin in itself will fail to make sweet music for the listeners if not strummed with a bow. The bow is the instrument by which a Violinist makes his instrument sing. His expertise in the use of the bow produces the violins varying tones and pitches. How a bow is shaped and the different parts that form the bow all work together to form the best bow for violin playing. A bow is most often described as an arc shaped piece of wood that has a flat horsehair piece stretched and tensioned across the wood. The tips of the bow are pointed on one end and rounded on the other. Although the violin enjoyed various incarnations as it gained popularity and was played by chamber and orchestra musicians, the violin bow did not keep up with these changes. This led to a total redesign that resulted in what is known as the modern bow. The modern bow is believed to have first made its appearance in France during the 19th century at the hands of the Tourte family. The Tourte family is considered by the violin historians to be the bow maker equivalent of the Stradivari family in violin making. The modern bow has more tension and resistance and uses Pemarnbuco wood as wood stick. Sometimes, makers will add subtle modifications to the bow in the hopes of producing a more handy and usable bow. Admittedly, not much has changed in the 150 year history of the bow. The violin and bow can be thought of in terms of milk and cookies or coffee with cream. One always enhances the best aspects of the other in order to produce a very significant experience for the person whose auditory and sensory perceptions participate in the resulting enjoyable final product of the merging of the 2 instruments.

Examining The Dangers Of Social Networking Media Essay

Examining The Dangers Of Social Networking Media Essay Social networking websites are web based services where one can create a public profile within almost virtual community. One can have a list of other users (friends) with whom they share a connection with, as well as view information on friends of friends. The main purpose of social networking sites is to build relations between friends who share similar interests. Most of these sites provide instant messaging and email services but are on a high level so that there is an element of complexity eg special software application tools are available in facebook which increase the users presence on that website. . Social networking recently has become a major part of the internet. In fac,t social networking sites are everywhere, nearly every person who has access to the computer and internet indulges with social network related sites on daily basis. Commom sites such as facebook, MySpace, hi5, Bebo and YouTube have millions of visitors daily. Facebook alone, has over 500 million users which make it the most popular social network website on Earth. According to Facebook , 50 % of their users are active users who log on facebook daily and People spend over 700 billion minutes per month on Facebook. The rapid increase in popularity of social network such as facebook has encouraged organisations to allow access to these sites within their networks. However many people now question social networks, the popularity of these sites has raised both security and privacy issues of its users. Millions of teenagers and adults exchange and share their personal interests and personal information such as photo s, videos etc, therefore one can learn almost anything about someone or stranger (If the profile page is open to anyone) who they maynot have met before, from their birthday to who their friends are and other personal information such as relationship status. There are many problems and dangers in using social networks however in contrasts there are considerable benefits of using social networks. Social networking is undisputedly one of the easiest way to keep in touch with family and friends as well as a channel in meeting new people with similar interests. One can make connect with people not presently in conact, for example staff in an organisation, students or alumni. Thus, social networking has made it very easy to make new friends or even meet old friends, which is a major benefit of social networking. Now, within the business world, social networking sites can also provide easy opportunity for anyone to advertise. This could either mean advertise an upcoming event or any other form of business advertising. The most important benefit of social networking sites like facebook or MySpace is that it gives an individualan opportunity to create an image of themselves through their profile, in a way he or she wants to be represented. It also gives them the chance to express themselves. There is a strong sense of being able to express ones own creativity. For this reason people find the sites almost personally fulfilling to be part of. Social networking sites have considerable benefits in allowing users to keep in touch with one other. Before social networking, people were only able to stay in touch with friends, families via phone, emails letters or online messengers, but it was very awkward and difficult to maintain contact due lack of communication tools. But sites like facebook have made staying in touch with people much easier where user can also emails as well as do live chat. Use of mobile phones and home computers with cheap internet has opened the doors for users all over the world, thus social networking has rose more than ten fold in the last decade. There is more pressure on people to use the sites because it has becaome almost part of modern living. The benefits somewhat seem to outweight any disadvantage even though the general public may not know at length where significant dangers lie in not setting appropriate User boundries for the applications or not using the applications with care and security. Social networking allow individuals to express themselves. The most popular way for an individual to express them self is by creating a profile which gives basic details about their personality such as personal interests, hobbies and education etc. One can add there details of hobbies and interests which might envoke other users to remain contact with similar interests and create social network between them. Social network sites, such as MySpace allows user to be creative by letting them design their own profile with different colour schemes and background pictures as well as using their own html codes for different layouts. Users such as music artist or writers can also show their creative side by writing blogs to let people know what is going on in their life. Creative artists such musicians, actors etc often use social networking to expand their fan base by using their profile in effect to advertise themselves. They can also get rapid feedbacks on any expressedtype of new ideas fr om their fans However despite all the positives of social networking the negatives overshadow the positives. Social networking has completely changed the nature of privacy by allowing individuals to obtain information of one individual without much effort. Social networking sites do not educate their users of apparent or hidden dangers in publishing their personal information on the World Wide Web. Even if a user is cautious about protecting their privacy it is very difficult for them to absolutely control who can view what on their profile pages. Most of the social networking sites have privacy tools which are not flexible enough to protect users data. This is because they have limited options of just to make the profile private (only friends can view it ) or public ( every one can view)à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.. Social networking has also provided a new way for phishing and scamming to fraudsters. Scams can be posted as comments on an individuals profile or sent as private messages. This could encourage users to click on links that might link to fake version of that social networking site asking to enter logging detail or any other personal detail. This site might have no functionality apart from redirecting the user back to the original social networking site after the user has entered his/her login detail. That way, the scammer can use the login detail to have full access to the victims profile, which then can be used to scam more users and sell their personal detaisl on black market. According to Symantec monthly report [10] on spam phishing, 92 % of phishing scams were carried out through social networking sites. This shows that social networking is a leading area for scammers to either steal personal details or send spams. Figures from fishtank.com [11] show that FaceBook is the 7th mo st targeted website of phishing scams in 2009, this figure might have increased in 2010. According to the article in the guardian paper, lately many phishing attacks have been carried out through Facebook , fraudsters have sent spam messages to users which link to the fbstarter.com or fbaction.net. These sites were phishing scams which looked as if they are Geneon sites, but were used to steel login details of facebook users. However facebook has announced that they have blocked the fbaction.net links from facebook website and messages that links to fbaction.net. Social networking is very common in teenagers or underage users. Most of these teenagers dont take into account or acknowledge the dangers of social networking sites. To them, all the social sites seem innocent. Most of these kids use these sites only to stay in touch with friend. Social networks are a hub for paedophiles and perverts. This is because majority of the children post too much personal imformation. Not just their name, but they post their photos, addresses and the school that they attend. Social networking sites provide neccessary information that these criminal predators need in order to target vulnerable kids. Majority of the parents are also not aware of common dangers in misuse of the sites. Also they may be unaware that their child has access to them or worse still is addicted to them. There are reports, worldwide, of grave concequences of children being involved in such incidents where sites have provides a main medium of communication with the children putting the mselves in dangerous situations. Facts show that out 10 teenagers, at least one has posted a nude/semi nude photos of them self on their profile [15]. An adult can become aware enough and handle all ofl the dangers of posting personal information on a social networking site but it might not be obvious to children, since they simply are not mature nor have developed enough,in mind, to comprehend the complexity of social networking. However, this danger could be prevented if children not only educated about what they should post on the profile and how they should post restricted material but also protected. Carers or parents should know what children are exposed to and what activities they conduct. The use of privacy settings on sites such as facebook can also help to prevent these dangers. One interesting aspect is when an employee can overlook his /her posting on any social networking site and talk about themselves for example to a potential employer. Thay may present a picture of themselves completely differnt to that of the one on thir social site. How are they to know that these details have not been viewed by that person. One example is that they may tell a lie about their whereabouts to someone only to discover that they have found the truth about them on a social site eg on holiday or out shopping instead of sick, at home and off work . It is clear that there is evidence suggesting that social networking is very dangerous indeed, but it is very difficult to ignore social;l trends locally and on a global scale. Can we live without a system that has breeded into our society so rapidly and deeply that it has an impoact on our day to day habits, even sleep is effected. Some people are suffering from an insomnia syndrome due to addictions on ef facebook poker and Farmville and the worrying issue is that the users are now the very young ones, small children. One great disadvantage is the impact on verbal and communication skills for children. The findings are is that children are missing out on being verbally competent, thay are learming to speak properly later in life due to chatting on the internet, thay are more shy or reserved. This danger is one of the impact on society and the future generation. Insead of talking and reasoning verbally, they are typing into the keyboard. Perhaps talking on the phone is better for humans because true emotion can be expressed and maybe we use a different parts of our minds. How much control do you think we will have over this. Social networking is here to saty because Such a big user level No one person has control over it Too many uses Will always be delveoping Too much meny to be made in it May be part of our future jobs May need it for Dangers have to be managed Are there but its have they are controlled/stopped/ Have to have a deeper understanding of what danger is, its impact on us today and toimarrow.. learn from mistakes and continuously work together to protect people and educate them Face [10]http://eval.symantec.com/mktginfo/enterprise/other_resources/b- state_of_spam_and_phishing_report_02-2010.en-us.pdf [11] http://www.phishtank.com/stats/2009/03/ [12] http://www.guardian.co.uk/technology/2009/apr/30/facebook-phishing-scam http://www.yourteenager.co.uk/facebook-your-teen.html http://life.familyeducation.com/teen/internet-safety/57657.html?page=2 [15]http://articles.sfgate.com/2009-08-10/news/17175229_1_social-networking-sites-social-networking-teens

What is Intelligence? Essay -- Biology Essays Research Papers

What is Intelligence? Intelligence can be defined in many different ways since there are a variety of individual differences. Intelligence to me is the ability to reason and respond quickly yet accurately in all aspects of life, such as physically, emotionally, and mentally. Anyone can define intelligence because it is an open-ended word that has much room for interpretation. Thus my paper is an attempt to find the meaning of human intelligence. There are a couple of scientists who have tried to come up with theories of what makes a human being intelligent. Jean Piaget, a Swiss child psychologist, is well known for his four stages of mental growth theory (1). In the sensorimotor stage, from birth to age 2, the child is concerned with gaining motor control and getting familiar with physical objects. Then from age 2 to 7, the child develops verbal skills, which is called the preoperational stage. In the concrete operational stage the child deals with abstract thinking from age 7 to 12. The final stage called the formal operational stage ends at age 15 and this is when the child learns to reason logically and systematically. (1) Piaget's theory provides a basis for human intelligence by categorizing the major stages in child development and how they contribute to intelligence. Each of these invariant stages has major cognitive skills that must be learned. Knowledge is not merely transmitted verbally but must be constructed and reconstructed by the learner (3). Thus this development involves a few basic steps. The first fundamental process of intellectual growth is the ability to assimilate the new events learned into the preexisting cognitive structures. The second fundamental process is the capability to change those ... ...ists approach in defining human intelligence. I believe that intelligence is the ability to utilize our entire brain, which will most definitely include Gardner's theory but more. Since we only use a small percentage of our brain, I imagine our brains have a lot more forms of intelligence than the ones Gardner proposes as well as more stages of child development than the ones Piaget proposes. As I mentioned before, intelligence is an open-ended word that may never have an agreed upon definition, but we all have our own definition.

Emma is a novel about youth through self-knowledge. Discuss. Essay

Emma is a novel about youth through self-knowledge. Discuss. The learning processes that are experienced through youth often lead to greater self-knowledge. This idea is readily demonstrated in Jane Austen’s â€Å"Emma† where the protagonist is established as an esteemed individual, living in the comfort and indulgence consequent of the limitations of her rural society. It is only when Emma opens herself to new experiences that she matures from one who lacks self-knowledge to a fulfilment of self-knowledge. The various events that occur ultimately challenge her viewpoint of the world she lives in. Emma’s dealings with befriending and matchmaking Harriet and her misinterpretation of clues given by Mr Elton and Frank Churchill are events which lead her to first lose confidence in her judgement and which later propels her to greater self-knowledge. Mr Knightley is a key figure in her process of change, leading her to a greater acceptance of others’ viewpoints. At the beginning of Austen’s novel, Emma Woodhouse is established as the central character of the novel who suffers from a lack of good judgement and awareness of the world she lives in. Austen establishes this idea through her opening sentence, conveying the idea that Emma is â€Å"handsome, clever, and rich†. The responder is given the impression that she thinks rather too well of herself as she has â€Å"been mistress of his house from a very early period†. We are told that she has been spoiled and indulged by â€Å"a most affectionate, indulgent father† and governess whose â€Å"shadow of authority being now long passed away†. The praise that Emma receives from Mr Woodhouse, Mrs Weston and Mr Knightley is warm acknowledgement of her education and accomplishments but is... ...tain self-knowledge. The various events that occur during the course of the novel develop Emma into a rounded individual who possesses a wealth of self-knowledge. This was not achieved without the aid of new experiences that penetrated the stability in her life, largely through the limitations presented by Highbury society. Emma’s overconfidence in her own judgement and her misinterpretation of clues given by Mr Elton and Frank Churchill, are important learning processes in Emma’s education. With the good judgement of Mr Knightley and her own self scrutiny, Emma is provided with the impetus to improve on her faults. Her growth to maturity and correct judgement ultimately leads to an attainment of greater self-knowledge. In balance, it can be seen through the character of Emma Woodhouse that â€Å"Emma† is blatantly a novel about youth through self-knowledge.

Poetry and Original Sonnet

Sonnet 69 was written by Pablo Neruda in the 20th century. As I was reading the original sonnet, I was filled with inner joy and love. The original sonnet brings profound feelings, flashbacks, and makes you and the sonnet feel as if one. However, the translation of sonnet 69 does not. It is rather dull and brings no sense of joy. In sonnet 69, the type of figurative language that is being used is hyperbole; which helps create emphasis. In Stanza 2, the line â€Å"like the red beginning of a rose† compared to the translation â€Å"like the red origin of the rose† contrasts incredibly.The word beginning flows more naturally, goes along with rose, and simply sounds better. The word choice of origin in the translation does not quite go along with the rose and it does not flow naturally. One major part that incredibly brings feeling is the last stanza. The original sonnet wins because of the way it is written. The first two lines end with commas, which builds up mood/feeling . Then it ends with a period, which tells you it is the end of the whole feeling. In contrast to the original one, the translation version does not even flow.The first line ends with a period, which does not build up feelings. In addition it uses too many words, which turns into a tongue twister. The original Sonnet and the translation both are different grammatically. The second stanza in the original sonnet ends with a period, while the translation ends with a comma. I think the period was the better choice because the sestets start next, which is something new. Lastly, I think that the original sonnet captures the concept of love rather than the translation.
