Read Nancy Herthers Digital Natives and Immigrants - Essay Example A sad parent tried to sue MySpace website because their daughter got sexually assaulted (Fleming, 2008). The US District Court Judge dismissed the claim by stating that it was her parent’s duty to protect their child not of MySpace. Fleming describes the whole process of how the online community works. She portrays it in such a light that there is repulsion felt by the reader even in processes like making friends, setting up an online profile or sharing or liking each other’s posts to spread the message. Fleming’s style is a little exploitative when she stresses too much on one side of the picture because online networks like YouTube, MySpace and Facebook are not only used to advertise the most personal thoughts across the world. Different online groups have grown on such platforms where people have find their old friends. They start many good things like projects, work groups and businesses together. However, Fleming needs to portray it in such an emotionally re pulsive light because the crimes committed under exploitation of social media are so heinous that one needs to exploit the truth to make the point. Sometime persuasion requires little bit of exploitation to get the point

Government Influence on Media Debate

Government Influence on Media Debate Mass media is the vital means which keep people informed about event and news over the world. It is one of the most important stages to communicate and transfer information. Obviously, people receive external and internal news anywhere even they busy by listening radio and/or reading newspaper, magazine and internet. That mean mass media is the most powerful tool of communication. There are many kinds of media such as newspaper, radio, television and internet. It is useful for entertainment, advertisement and news around the world. Mass media has positive and negative impacts on the audience. That mean should be censorship to assess mass media and make it suitable for all audience. It would argue that some people believe that government should not influence on the mass media. However, others think that the government should control the mass media. In my opinion, I think that the government should have responsibilities and duties to control mass media. In this essay will write about advantages and disadvantages of mass media. Then I will discuss about the government should involve in regulating forms of influence on news, violence program, advertisement, sexual themes and education. After that I will mention some suggestion about media. Mass media has positive and negative effects on the people. There are many of advantages of media. First of the advantages, it helps you to increase your knowledge by reading articles in newspaper or watching TV program. Second, it keeps you inform about news internal and external world by listening to radio. Third, it helps you to improve your skills such as reading and listening. Moreover, magazine or TV advertisement obtains best offer for perfect product. On the other hand, if you followed the media extensively it could cause negative impacts such as media may cause obesity because setting long time read, watch or listen. Furthermore, children or young might learn bad habits like smoking or eating drugs because they imitate hero in film. In addition, people may miss some skill like speaking fluently because they learn to read and write with media. In many places around the world people believe that news take part in human life. The people want to know every events that happen around them. Therefore, mass media makes report daily and monthly to keep people informed. Also it reflects the news in best way to affect on people and make them happy to follow the broadcast. Audience might not trust any information sent to them by newspaper or television because fake news influence on the true news. Sometimes the media broadcasts the events in different way or it changes some parts in this events to attract people. Producing fake news may led to make serious problem between people and government entire the country or between two countries. The government should contribute many efforts to regulate the mass media by providing censorship for all kinds of media. Moreover, encouraging the media to make news in easiest way to understand it clear. That means the media not allows to establish programs or report without assessment from the gove rnment. For instance, when the newspaper and/or television produce report they need to have permission to establish it. Watching horror films and excessive violence programs seem good way to spend free time for young people. They set at home or they go to cinema to watch these program in terms of fun and entertainment. These programs design to make you concentrate on the events and try to think what could happen at the end. In this kind of program may show crime unreal like monsters or real but fake film like murder kill people. Excessive watching horror and violence cause many problems for young people especially children as the following. First of all the attitude, mood and behavior will change to worse such as speaking of young uncivilized because they imitate the film. Second, it might make children less sensitive to the pain and suffering of others, be more fearful of the world around them and be more likely to behave in aggressive or harmful ways toward others. As result, the government should notice that and teach the parents to look after their children and keep them away. The government shoul d obtain the instruction of any program by provide legal age to watch it. For example, some films indicate the suitable age to watch the film to prevent children from any violence. In many companies around the world use the media to advertise their product. The companies pay huge amount of money to show the product in the media. Usually they target children in advertisement which help them to sale goods. They create best broadcast by using famous hero use this product which attract children to buy it. Also, they use carton film to advertise product by doing unbelievable thing. That might make children believe that unhealthy food make you strong. Watching a lot of advertisements cause negative effects on children such as child believe every think in the media and do not realize the broadcast made for commercial and get money. Therefore, in my opinion the government should limit the advertisement or reduce time broadcasting. Moreover, the government should encourage companies to make broadcast with positive goal such as encourage children to eat fruits or mention in broadcasting some benefits of vitamins. In the visible media use attractive and sexual people to show the program like television and internet also in magazine they use photos of beauty girls. This kind of show to attract people and make them concentrate in the program. Companies provide beautiful girls an handsome boys in terms of fashion. The companies effort the worker more attractive to attract people and sell product. For instance, the companies use semi-naked girls to advertise hair care products, shaving blades and creams and/or body soaps. Some of the boys and girls do strong diet to be slim like the actors or actress. This may cause negative effect on their life such as cause some disease. Moreover, the people tend to watch romantic films which contain a lot of sexual themes. Also, some adult watch sexual films in terms of entertainment. However, the children will watch most of unacceptable themes in television or internet. This will encourage children to do earlier sex and do not care about wearing naked cloths. Because the children do not know sham and they think do right. This issue should solve by government. The government influence on the media by provide suitable age to watch and delay the broadcasting until mid night to be ensure children sleep. The mass media source of information for people so it work hard in terms of education which is the important concept in our life. Media provide variety programs to educate people. There are many program in history and culture in different countries. These broadcast to keep you informed about your traditional culture. Moreover, mass media will increase your knowledge by providing a large number of competition programs. There are many channel provide documentary and scientist material to give you view about the nature. Also, some magazine and newspaper provide different subject and games help you to think. These programs useful for all ages for example children may learn to read and write through TV or magazine. I think, the government keep encouraging mass media to improve the part of education. Furthermore, the government should give the media motivation to work hard and to keep going. Before the end of this essay I would mention some useful suggestion to help us to get benefits of media. First of all, the government should encourage people to read books by giving people pursuers about importance of media and how we use it in correct way. Second, the people should notice list for good program also do not concentrate on TV or internet only but you should read. Third, the parents should look after their children by deleting some channels from TV or band TV at the midnight and help them to understand the correct way for the media. Finally, I would say you should do sport to keep your mental awake. To sum up, me and some people believe that mass media plays a fundamental role in our life. It seems that mass media is the quick way to connect between the government and individuals. Therefore, the government should control mass media to promote education and development target also to protect young people from misleading habits.

Cleopatras Initial Encounter With Caesar Essay -- Egypt History Paper

Cleopatra's Initial Encounter With Caesar Cleopatra is desperate-she needs to gain the throne of Egypt before her inadequate younger brother, Ptolemy, convinces Caesar to grant him full power. But alas, Cleopatra has been banished from Egypt by the ruthless Pothinus. Fortunately, the brilliant Cleopatra devises a plan to enter her Egyptian castle rolled up in a carpet, posing as a gift for the great Caesar. Her loyal servant, Apollodoros, carries her through a secret passageway and into the palace, where they are met by Caesar's guards. They continue into Caesar's quarters, where Apollodoros unrolls the carpet to reveal the stunning Cleopatra. Caesar is impressed not only by Cleopatra's intelligence, but also by her undeniable beauty, and pronounces Cleopatra the sole ruler of Egypt. Such is the story of the meeting of Caesar and Cleopatra as told by Plutarch and others that followed him. The extent of the story's truth remains a mystery, but it is likely that Plutarch included it in his account merely for entertainment value-it is only fitting that the alluring Cleopatra enters the castle with such a grand appearance. Because it is written in Plutarch's interpretation, many perceive the story as fact and include it in their own works. The scene, however-and the portrayal of Cleopatra within it-vary among different compositions. Regardless of the probable fictitious aspect of the scene, it is an important one, for it is in this scene that the level of Cleopatra's strength and power is revealed. INTELLIGENT YET INFERIOR Initially, it appears as though the rug scene is a display of Cleopatra's wit, for she uses her intelligence to devise a plan to enter the palace.

Advantages and Disadvantages of mobile phone Essay

Cell phones are a great invention and a popular way to communicate—half of all Americans and Europeans use one. They allow us to work on the go and stay in touch. When put in the hands of a teenager, however, they can have some effects of which adults should be aware. It is a common sight – cell phones (mobile phones) in the hands of people, especially teenagers. Literature has provided in-depth evidence of the uses, advantages, disadvantages, impact, consequences and concerns about the use of mobile phones. Why teenagers fancy this device, is an interesting observation where the experts attach its significance to teenagers’ identity factor. The usage of mobile phones has re-shaped, re-organised and altered several social facets. Particularly focussing on teenagers’ mobile phone usage, literature has provided evidence of them being used for both positive purposes and negative reasons. Is the gap between uses and negative impact widening? Are consequences and concerns superseding positive uses? How do parents/caregivers perceive the overall usage of mobile phones by their teenagers? Are there any solutions, possibilities and avenues to address such problems? These are the basic queries that drive this study. PACG is the acronym for parents/caregivers used in this document. Objectives: This study is centred around parents/caregivers’ (PACG) perceptions of their teenagers’ mobile phone usage: †¢ To gain an overall understanding of teenagers’ mobile phone usage (positive purposes and negative impacts) †¢ To understand the influence of texting on teenagers (such as text language on proper language, text messaging on communication skills) †¢ To understand the effects on teenagers’ physical (such as driving, health) and psychological (such as bullying, un-monitored time usage, family time) safety issues. Methods: A mixed methods approach was employed to explore the research problem. Quantitative data was collected through questionnaires (18 closed and 02 open-ended questions) and qualitative data through interviews (approximately  21 questions). The survey and interview participants were parents/caregivers of teenagers aged 13 to 19 years irrespective of their teenagers’ mobile phone possessions. They were broadly divided into seven ethnic groups. 115 PACG completed the questionnaires through survey and 07 participants from the survey sample were interviewed (one from each ethnic group). Results: Teenagers possessing mobile phone/s were 96.5% (n=111). A further breakup of age groups indicated that all the 17-19 olds had mobile phones. In addition, not possessing mobile phone/s is higher in the age bracket 15-16 year olds when compared to 13-14 olds. Chi-Square tests established significance between independent and dependent variables, in the following relationships. The results are briefly mentioned. †¢ ‘Gender’ with ‘teenagers sharing with PACG, if bullied: A high percentage of PACG said that their teenagers share with them if they are bullied. It was also evident that girls share more with PACG, if bullied, than boys do †¢ ‘Ethnicity’ with ‘Interruption of personal time with PACG’: A high percentage of PACG said that their personal time is to ‘some extent’ interrupted due to social bonding enabled by their teenagers’ mobile phone usage †¢ ‘Ethnicity’ with ‘PACG feeling secure with teenagers’ un-monitored times usage’: A high percentage of PACG said that they feel secure with their teenagers’ mobile phone usage during un-monitored times †¢ ‘Ethnicity’ with ‘PACG feeling using mobile phones while driving is risky’: A high percentage of PACG said that using mobile phones while driving is risky †¢ ‘Ethnicity’ with ‘PACG feeling to ban mobile phone use while driving’: A high percentage of PACG supported a ban to use †¢ ‘Ethnicity’ with ‘PACG feeling to have an age limit to possess a mobile phone’: More than fifty percentage of PACG supported a minimum age limit for possessing a mobile phone either by saying ‘yes’ or ‘probably’. Conclusion: Parents/caregivers of this study express both positive and negative impact towards teenagers’ mobile phone usage. On a positive note, PACG perceive that mobile phones are very useful devices for communication and co-ordination of activities. They also find that they are compulsory as they are used as safety devices especially in emergencies. Voice and text features are considered as the basic required facilities in teenagers’ mobile phones by PACG. On the negative side, PACG express that teenagers are  addicted and obsessed with texting, while some of the PACG feel that it distracts the teenagers from their study time and other important activities. Some PACG hold the service providers responsible for this because of texting plans. Bullying and abusive messages have been perceived as the major problem mediated by mobile phones. PACG express that teenagers with their mobile phones are out of control for them. They also add that teenagers lose control over the information enabled by their mobile phones. Every interviewed PACG expressed concerns on internet access via teenagers’ mobile phones. The overall findings from this study reveal that parents/caregivers’ perceptions of teenagers’ mobile phone usage are not satisfactory. Although they express a mixed opinion, they lean towards negative impacts. A very high number of interview participants expressed the view that negative impacts outweighing positive purposes with teenagers’ mobile phone usage. This further leads to recommendations from PACG on proper usage, future research, avenues and possibilities to implement solutions for problems. PACG mainly perceive that educating teenagers (on consequences and tackling issues) and providing mobile phones to teenagers from the age of 14 years (the legal age to stay home unsupervised and mature enough) will help in ameliorating the negative impacts. In addition, PACG support to ban using mobile phones while driving. These are the outcomes of the study Cell phones and mobile phones are the main invention of modern technology and also have historically been given to human beings to send messages, entertain and ultimately help them make life easier. Also, cell phones have become one of the fastest growing communication technologies. Although mobile phones have greatly facilitated people’s lives, people more and more depend on using cell phones and cannot leave it frequently, especially young people nowadays. There is no denying that cell phones bring a wide variety of benefits to teens, but it also have many negative side effects to teens no matter for their health, study habits and behaviors. Therefore, I believe that the usage of mobile phones should be limited to a wide range of teenagers because the advantages far outweigh the disadvantages. To begin with, if we confine teens to use cell phones will make their campus and social life become inconvenient because cell phones allow teenagers to keep in touch not only with their friends, but also with family members, schools and emergency services. Dr. Stefania  Kalogeraki points out â€Å"mobile phones provide a direct communicative channel between teenagers and peer groups, parents and children; therefore the device enhances social interactions and bonding with peers and family†. Despite of the fact that mobile phones can be the excellent tools to stay in touch with people; it also can be a weapon for young people to hurt themselves. Cell phone becomes an addition for a large amount of teenagers around the globe, and its use by this age group has many disadvantages with short-term and long-term consequences. It also will cause lots of jumbo problems for youngsters without proper supervision and responsible use. For their health, radiation, this is the biggest issue for young people who use cell phones everywhere, every day and even every moment. Dr†¦ Cell phones are there to make communication and life much easier, but people engage regularly in multi tasking when they are behind the wheels. â€Å"Cell phones are a great invention and a popular way to communicate—half of all Americans and Europeans use one. They allow us to work on the go and stay in touch, however there are ways in which cell phones can affect teenagers† (Reynolds, 2012). It is important to understand the effects because although â€Å"parents see †¦ cell phones role as a mixed blessing for their teenagers, it can bring distressing things into their lives’’ (Lenhart, Madden, Smith, Purcell, Zickuhr & Raine, 2011). What are possible effects of cell phones on teenagers? There are several ways in which cell phones can affect teenagers, such as educational, social and health, which can all be both positive and negative. Social effects of cell phones can be sex-ting, cyberbullying and social networking. Educational effects are effects relating school and education of a teenager. Health effects are health risks and benefits for a teenager while using a cell phone. There are m any different effects of cell phones on teenagers but the most important ones that are mainly looked at are educational, social and health. This essay will cover the positive and negative educational, social and health effects of cell phones. Positive Effects of Mobile Phones Communication Convenience Mobile Phone is the best way to communicate. We can stay in touch with our  loved ones anywhere, anytime, just because of mobile phones. All thanks to their small size, lightweight, that make them portable. Entertainment Life is nothing less than a hell without any entertainment in it. Thanks to mobile phones that let us entertain while on the go. The mobile phones getting launched nowadays, come with super impressive features related to entertainment. Mobile manufacturers know it pretty well that entertainment is demand of today. This is the reason why mobile phones are nothing less than a complete portable entertainment devices. Useful in Studies and Business Mobile phones are quite useful in studies and business. In both fields, the mobile phone has become like compulsory gadget. Students can access Internet on their mobile phones while on the go, and thus can get knowledge of any topic they wish to. The business persons can keep updated with the markets up and downs, can stay in touch with their employees and clients. Work as Boon in Emergencies Just consider any emergency situation in which you want to talk to your friend, relative or anyone else? Mobile Phone is what works as boon in such situations. You might have faced any emergency situation in which mobile phone helped you, have you? Whether you have faced it or not, it’s quite easy to understand the role of mobile phones in emergencies. Boon is what we can call the mobile phones in such situations, right? Negative Effects of Mobile Phones Bad Impact on Studies The students are just addicted to mobile phones. They can be seen playing games, chatting, and talking to their friends on their mobile phones most of the times. This is the reason why they don’t get time for studies. In fact, students are more interested in wasting their time on mobile phones, rather than spending it on studying. Accident and Health Issues Most of the accidents that happen daily arise because of mobile phones. The  mobile phones have resulted in dangerous driving, whose direct impact can be seen in increasing no. of accidents. Apart from accidents, mobile phones have bad impact on health as well. Several researches conducted by the health experts have proved the bad impact of mobile phones on health. These are the positive and negative impacts of mobile phones on our lives. These is no doubt mobile is a necessity these days, but we should take care of the negative points too and use this technology accordingly. the influence of mobile technology on our lives is huge and even greater on teenagers. In the age in which they’re developing as individuals all that mobile phones birng leaves a strong trace on their growing up. The usage of mobile phones in their age should be controlled but they shouldn’t be discouraged from using them as they bring many benefits. Positive Effects on Teenagers That it provides a sense of security for teenagers as well as their parents, is one of the prominent argument that is put forth by those in favor of cell phones. You will seldom come across someone who doesn’t understand the importance of cell phones or who hasn’t used his/her cell phone in times of emergency. It is this convenience of reaching each other, both for teens and their parents in emergency situations, which makes cell phone one of the most important devices in the world today. At the same time, the recently launched handsets with GPS on board are also of great help, considering that the parents can now keep a track of their child’s whereabouts by tracing his cell phone in real time. Not to forget, cell phones have also given a boost to social networking by giving teenagers the ability to reach out to more people. Negative Effects on Teenagers While terms like safety and connectedness may give the rising trend of cell phone use by teenagers a thumbs up, there are quite a few negative aspects of the same which have put it under the scanner of late. For instance, studies reveal that those teenagers who are addicted to cell phones are prone to sleep disturbances, anxiety and depression. Other than these psychological problems, the use of cell phones is also known to come heavy  on our eyes and thumb in form of repetitive strain injuries – which are similar to those injuries that are caused as a result of using the computer for extended hours on a regular basis. Even though the researchers are divided on this, there do exist some studies which associate cell phone use with brain tumor and low sperm count. While cell phones may improve socialization for teenagers, it restricts the kind of people that these teens come across and widens the gap between them and their parents. Distracted driving is by far the worst of the various negative effects of using a cell phone, with thousands of accidents – mainly those involving teenagers, being attributed to the very trend of attending calls or texting while driving. At the same time, the critics also highlight the fact that the device which was predominantly devised for communication and entertainment is also being used for a lot more than that of late, and accessing pornography is just one of these activities. Initially, it was the computer that was the main source of banned pornographic material for teenagers, but the advent of multimedia cell phones has made it a lot easier for these teens to access pornographic material which ethically they shouldn’t. Similarly, sexual harassment in form of sexting – sending lewd messages, or making porn videos and circulating them, is also on rise. While cyber bullying has been one of the most talked about issues related to Internet use, a relatively ne w but similar concept referred to as ‘text bullying’ is slowly gaining steam especially in school environment. All these arguments and counterarguments has made this topic one of the heated subjects of debate of late. The argument on safety is no doubt justified, but that happens to be one of the very few positive effects of cell phone use – especially with the negative effects of this practice existing in plenty. Overuse or abuse of cell phones cannot be justified at all. It is this blatant abuse of cell phones by individuals belonging to the age group of 13-18 that has put it under the knife for all the wrong reasons. At the end of the day, technology can be of great help when used in correct manner – its misuse, on the other hand, can spell disaster for the user. Negative effects: Physical- mobile phones can affect you, such as brain damage. Mental-mobile phones could interrupt studies. Emotional-mobile phones could cause to phone bullying. Social-the wrong person could get hold of mobile number, so be careful. My objectives are to gather information related to my question, to learn more about mobiles phones having an effect on our youth today. I will carry out my research by exploring the internet, researching books and I will also ask other people what they think about the question for my project. History About Hexagonal call technology When mobile phones were first introduced to the public they had used a technology called the hexagonal cell. Hexagonal cell had enabled the first mobile phone to work, this was developed by Bell Labs. â€Å"Hexagonal technology allowed mobile phones to be used while on the move, this was done by transmitting wireless signals from one tower to another†. This technology had enabled mobile phones to gain reception from anywhere when on the move, this works by the mobile phones transmitting phone signals to the nearest tower to you but when on the move it does this quicker and it is always moving to other towers to get good reception for phones. Good effects of using a mobile phone Travel Safety It is a good idea to let a family member or friend know where you are, where you are going next, and when you arrive. This is good for teenagers to let there parents know if they are alright. Traffic Problems A mobile phone is handy to have to inform the person that you are late and you could come to an arrangement about the time you will arrive. Accidents When we least expect it, accidents happen. Some can be minor accidents and some can be major accidents. If the accident is bad and you need to call for help such as an ambulance to come and help you. This is a big help and you can call for help by using a mobile phone and the call is for free. Staying in Touch Having a mobile phone gives you a privilege to stay in touch with people all over the world with a simple phone call or a text message. Teenagers are always on the phone to there friends. Finding Your Way If Lost This can happen to any of us, a mobile phone could help us get out of this. A mobile phone will allow you to make a call of your choice and you could ring a person to help you make your way back to wherever you want to go. This is good way to help out teenagers if they don’t know there way around. In Case of Emergency In case of an emergency a mobile phone is really useful to have, if you are in trouble with anything use your mobile phone to call 999, this is a free call but this is only to be called if in an emergency. If teenagers carry around a mobile phone they are more likely to be safer then not having one because this mobile phone will allow them to call the police if in trouble with anything. Bad effects of using a mobile phone Addiction Using mobile phones a lot can lead to addiction, especially to teenagers, as wasting time on communicating with people via text messages and phone calls. Auto Accidents Talking or sending SMS text messages on a mobile phone while driving is proven to be as dangerous as driving under the influence of alcohol. Sleep Loss Mobile phones cause’s teens and young adults to lose sleep, finding it difficult falling and staying asleep, this could increased stress and fatigue. Increased Expenses Mobile phone usage is expensive and can easily lead you to keep buying credit which can cause a lot of money if addicted, this could cause high stress levels. Environmental Effects Improper disposal of cell phones and their batteries can release harmful, non-biodegradable chemicals into the environment. Brain Damage Some Pros Are as following: – Parents can be in touch with their children and know their whereabouts. – Your kids can reach you in the event of an emergency and vice versa. – If in danger, your children can reach the authorities or a medical provider. – Phones can be silenced during class or study periods and active only in appropriate places. – Students can take pictures of class projects to e-mail or show to parents. Ordinarily, parents do not see projects that are completed in groups in school. – Students can text message missed assignments to classmates that are absent. A buddy system can be put into place. – Many cell phones are equipped with calculators-plenty of new math curricula encourage the use of a calculator when problem-solving. A student should become accustomed to having a calculator handy for both homework and real life math applications. Con’s of Cellular Usage – They disrupt the class with noises from the phone and ringtones and you can text other students during class and not pay attention. – Some groups have raised concern, for example, over the possibility of brain tumors, headaches, and dizziness. Others suggest that cell phone usage may have caused some reproductive effects in both males and females.

Free Essays on Manipulation In 1984 Free Essays on Manipulation In 1984 Manipulation in 1984 In the classic novel 1984, author George Orwell writes of a future country called Oceania in which there is nothing that the government doesn’t control. By limiting the country’s historical knowledge, manipulating their minds, and conditioning their bodies, Big Brother is able to undermine citizens and use them as puppets. Though American government isn’t as austere as the fictitious one in 1984, there are definite parallels between Orwell’s writings and today’s society. In 1984, The Party is in control of every source of information, including historical events occurring in the past and the present. One day at work, the main character of the novel, Winston Smith, has to â€Å"rewrite a paragraph of Big Brother’s speech in such a way as to make him predict the thing that had actually happened (pg. 35).† In other words, he must manipulate the words of an article in such a way as to not make the government appear as anything less than perfect. Winston writing in his journal daily automatically assumes that on discovering this secret diary, he will surely be put to death because it is not in favor of The Party and contradicts the very belief system of Oceania. Big Brother, so in control of his country and its citizens, is able to literally rewrite history. He is able to construct the way the world was, is, and always will be by simply having the words switched in a document so that it reads more suitably. This familiar condition is seen i n America on many occasions. First, so many documents and missions are marked classified and referred as â€Å"big government secrets.† What could the government be hiding? Surfaced scandals, such as innocent civilians being killed and secret bombings during the Gulf War, having information on terrorist attacks before the event occurs, and hidden documents about flawed big business industries, have shown Americans that not only is our government not perfect, but that th...

It is a reddish-orange or yellowish-orange fuming liquid. The term is a Latin phrase, meaning kings water. The name reflects the ability of aqua regia to dissolve the noble metals gold, platinum, and palladium. Note aqua regia will not dissolve all noble metals. For example, iridium and tantalum are not dissolved.Also Known As: Aqua regia is also known as  royal water, or nitro-muriatic acid (1789 name by Antoine Lavoisier) Aqua Regia History Some records indicate a Muslim alchemist  discovered aqua regia around 800 AD by mixing a salt with vitriol (sulfuric acid). Alchemists in the Middle Ages tried to use aqua regia to find the philosphers stone. The process to make the acid was not described in chemistry literature until 1890. The most interesting story about aqua regia is about an event that occurred during World War II. When Germany invaded Denmark, the chemist George de Hevesy dissolved the Nobel Prize medals belonging to Max von Laue and James Franck into aqua regia. He did this to prevent the Nazis from taking the medals, which were made of gold. He put the solution of aqua regia and gold on the shelf in his lab at the Niels Bohr Institute, where it looked like just another jar of chemicals. de Hevesy returned to his laboratory when the war was over and reclaimed the jar. The recovered the gold and gave it to the Royal Swedish Academy of Sciences so the Nobel Foundation to re-make the Nobel prize medals to give to Laue and Franck. Aqua Regia Uses Aqua regia is useful to dissolve gold  and platinum and finds application in the extraction and purification of these metals. Chloroauric acid may be made by using aqua regia to produce electrolytes for the Wohlwill process. This process refines gold to extremely high purity (99.999%). A similar process is used to produce high-purity platinum. Aqua regia is used to etch metals and for analytic chemical analysis. The acid is used to clean metals and organics from machines and laboratory glassware. In particular, its preferable to use aqua regia rather than chromic acid to clean NMR tubes because chromic acid is toxic and because it deposits traces of chromium, which ruin NMR spectra. Aqua Regia Hazards Aqua regia should be prepared immediately before use. Once the acids are mixed, they continue to react. Although the solution remains a strong acid following decomposition, it loses effectiveness. Aqua regia is extremely corrosive and reactive. Lab accidents have occurred when the acid exploded. Disposal Depending on local regulations and the specific use of aqua regia, the acid may be neutralized using a base and poured down the drain or the solution should be stored for disposal. Generally, aqua regia shouldnt be poured down the drain when the solution contains potentially toxic dissolved metals.

One of the most acknowledged artists, Tony Cragg - Essay Example The essay "One of the most acknowledged artists, Tony Cragg" discusses the Tony Cragg's career in arts and visual communication and analyzes his work, philosophy, and interactions with the wider society. Tony Cragg started his career in Britain as a laboratory assistant. His main duties in the laboratory involved testing, manipulating and developing various categories of rubber. Cragg took these duties while he was still an art student and therefore he utilized his artistic skill in all experiments that he conducted. Using his drawing techniques, he was able to express his experiment to an understandable level. His background in science is also considered to have contributed to his imagination and creativity. In 1970, Cragg joined the Wimbledon College of Art before he proceeded to the royal college in London. After completing his studies at Wimbledon, Cragg moved Wuppertal in Germany where he continued with his work in visual art. While in Germany Cragg utilized found materials such as broken glass, toys, plastics and metal pieces to produce his works. In 1980, tony Cragg began using bronze and iron as his major artistic materials. He also used other materials such as wood, polystyrene, and steel to cast bronze and iron. Due to complexities in his work, Cragg preferred producing all his sculptors using his own hands. Cragg had a team of assistants who assisted him with his daily work and requirement in his studio. His early forms took from his experiences and encounter with experimental work.
