Gamma Ray Penetration Of Lead essays

Gamma Ray Penetration Of Lead essays The amount of radiation that occurs to the matter depends on two things: what radiation is used. what material is used for absorption. There are three types of radiation; they are Alpha, Beta and Gamma. Gamma radiation has two types of radiation, nuclear which is dangerous and electromagnetic which is not dangerous. Gamma rays are the opposite of alpha particles in a way. They penetrate a long way into materials without being stopped. This means they are weakly ionising because they bend to pass through rather than colliding with atoms. Eventually they hit something and do damage. The only thing that block Gamma rays is thick lead and concrete. In the experiment I will be using lead. In 1896 Henri Becquerel was investigating materials, which glow when placed in an x-ray beam. Curious to find out if strong sunlight caused uranium salt to glow. It was clear that uranium salts emit penetrating radiation, which can blacken photographic film. More interested in x-rays, Becquerel passed the challenge of further investigations on to one of his students, Marie Curie. Within a few years, Marie Curie discovered other elements such as thorium, which are radioactive. One of these elements, radium, was found to be over 1 million time more radioactive than uranium. Photographic film can be used to detect radiation. Radiation was first discovered by accident when Henri Becquerel left some uranium on some photographic plates, which became fogged by it. These days photographic film is useful way of detecting radiation. Workers in the nuclear industry or those using x-ray equipment such as dentists and radiographers wear little blue badges which have a little bit of photographic film in them. The film is checked every now and then to see if it has become fogged too quickly, which would mean the person was getting to much radiation. The nature of radioactive radiation. Alpha radiation was s...

How To Use A Twitter Chat To Grow Your Audience

How To Use A Twitter Chat To Grow Your Audience Twitter has always been a quick and easy way to connect with other people and be informed.  You can publish your content and reach hundreds (even thousands) of people. Even better, unlike many other social networks, you can repost your original content several times to gain even more exposure. You can do more with Twitter than just share content, though. You can both  market your blog or business and make connections with top industry players from around the world. How do you do it? You get involved in Twitter chats. What Is A Twitter Chat? Youve probably seen a Twitter chat or two in your newsfeed. A Twitter chat is a conversation between a group of people on Twitter. To keep the conversation organized, a specific hashtag that fits the conversation is used on every tweet. For example, #SamllBizChat is a popular Twitter chat for small  businesses.  Everyone who participates will use that hashtag in their tweets, which makes a Twitter chat easy to find and follow. You can also follow a Twitter chat by using a website like TweetDeck  or Twubs. Finding a Twitter chat is fairly easy.  There are websites that have lists of Twitter chats, such as  Tweetchat,  Tweetreports. There is even  a  random Google doc  that has a ton of Twitter chats listed. You can also ask people if they participate in Twitter chats and which ones they like. Joining A Twitter Chat Joining a Twitter chat conversation is easy, once youve found one that youre interested in. As the tweets appear and questions are asked, hop right in and  answer a question. Thats all it takes! Dont forget to include the specific hashtag for the chat in all of your responses as you participate. Welcome! Thank you for joining us. Please remember on each tweet to use the hashtag #edchat Jerry Blumengarten (@cybraryman1) June 10, 2014 Most Twitter chats are  open, so feel free to participate. Its important that you are make comments that add to the conversation, though. Stay on topic and be respectful of the other participants.   Participating In A Twitter Chat The rules of participating in a Twitter chat vary depending on the type of Twitter chat you have joined. These different types of chats depend upon how they are moderated. Heavily Moderated A  heavily moderated Twitter chat will be in a question and answer format. The beginning of a twitter chat will begin with people introducing themselves. For example, if I was participating in #SportsPRchat then Id write, Hi, Im Krista and Im a senior @MSUM. I love everything PR related. So excited to chat with you all. #SportsPRchat The moderator will start a tweet with Q1, meaning Question 1. The proper response will start with A1, meaning Answer 1. There is no need to hit the reply button when you type your answer in Twitter. Just create your own tweet, start it with A1, and include the hashtag. That will make sure that your tweet is part of the conversation. You can reply to peoples answers if you have something to add or if you just like their answer. Q5: After the backlash online, was this a social media fail or an act of PR genius? The topic is still trending. (2/2) #SportsPRchat Pam Chvotkin (@reddusfoximus) June 4, 2014 A5. Epic fail team if they really wanted to keep name ! All they did was prove more people feel strong about changing it #SportsPRchat Ben Christly (@BenChristly) June 4, 2014 Lightly Moderated/Open A lightly moderated/open Twitter chat will be less structured.  Theyll usually start with a question or a topic from the moderator, and then its free rein. Theres more to a lightly moderated Twitter chat than just tweeting one answer. It is more like a natural conversation rather than a Q and A session. You can tweet your opinion without needing to start your tweet with A1 since no official question was asked. In an open Twitter chat, you are free to contribute to the conversation as it fits, which includes responding to what others have said.  If you like what they say, tell them. If you disagree, let them know. If you need advice relating to the topic, ask and people will respond. As always, be a respectful participant. #edchat Topic: With the hundreds of issues that effect teaching learning, what should be the primary focus for change in ed? Jerry Blumengarten (@cybraryman1) June 10, 2014 Twitter Chat Is A Marketing Tool Twitter chats are marketing tools, but they arent typical. They approach marketing in a direct manner and are highly conversational. A Twitter chat can be both business-to-business (because you are conversing with others in your niche) or business-to-community (because you are conversing with your audience). Here are a few benefits of a Twitter chat and ways to use it as a marketing tool. Connect and network in your niche using #TwitterChats.1. Twitter chat lets you interact with people. Twitter chats are all about interacting and networking with like-minded professionals in your niche as well as your audience.  They provide an opportunity to market your personal brand and blog, and educate yourself by staying on top of trends and changes that you should know about in your industry. If you want to build creditability and make new connections, you are going to have to respond and interact with people. It doesn’t take much. If you see a comment you agree with just reply and say, I agree! It could be as simple as that, letting them know you are interested. 2. Twitter chat promotes your blog. Twitter chats are a great opportunity to promote your blog. If you wrote a blog post about a specific topic and there just so happens to be a Twitter chat on that topic, then it would be a good idea to mention your post. Just make sure it is something that is valuable to the conversation.  If its a lightly moderated chat, some people may ask questions that your blog answers. Reach out and personally invite them to take a look at it. When promoting your blog in a Twitter chat, though, dont be overly aggressive. You wouldnt want to say A1. I wrote a blog post on this topic. Read it. Its important to build relationships and trust. Find a person who needs some advice, give them some advice and mention they can read more at the blog post you wrote about the topic. That shows you care about their concern and genuinely want to help them. 3. Twitter chat builds credibility. Honestly, you dont need to mention your blog too often. Just participate in a twitter chat and provide relevant and valuable information. Interact with other participants. If you are building relationships and providing valuable information, people will begin to trust you. Then when they find out you have a blog, they will be more likely to read it. They know the writer and they know the writer knows what theyre writing about. 4. Twitter chat is a good way to learn. Twitter chats can connect you with people that are in your profession from around the world.   It gives you an opportunity to learn from  people who are true experts in their field.  Stay up to date in your industry and keep up with current trends, technology, and best practices. A Twitter chat is a great way to stay relevant. You can also discuss things with people who have experienced things that you haven’t experienced. For example: people deciding whether or not to study abroad can read and interact with people in a Twitter chat dedicated to studying abroad on a budget.

Why strong economies should support countries weak economies Essay

Why strong economies should support countries weak economies - Essay Example The paper tells that aiding underdeveloped countries by the industrialized countries is a very noble character since human nature is protecting and helping others. It is therefore worth understanding that helping poor countries is an internationally common practice whose main motive is based on moral obligation. Aiding underdeveloped nations act as an additional resource that empowers countries to develop themselves economically by financing their own projects. A humanitarian concern is the main reason behind helping poor countries. Funds or any aid offered to an underdeveloped country by the industrialized nation may assist in carrying out very important projects and programs such as elimination or reduction of diseases and poverty. This is because most poor countries are not able to raise funds that can help them in undertaking such kind of programs. Aiding is important because ‘It’s a necessity in eradicating third world poverty’. Availability of cheap labor in the Asian and other colonized countries as well as slavery catapulted economic development of the developed countries. Also, for harmony and peaceful coexistence, industrialized nations should act responsibly by helping the poor countries. It should be noted that ‘it is a moral duty to help those less fortunate than you’. Assistance by the rich countries may also be accompanied with technological transfer particularly when the aid is technical in nature and this may be of great help in boosting the economic growth of the underdeveloped countries. Moreover, the aid may come with training and education that may be of great use in promoting various infrastructural and human developments that are useful in propagating economic growth. Indeed ‘aid helps train teachers, buy textbooks for school’. Issuing aids further help in promoting the relationship between the developed and underdeveloped countries. By supporting countries experiencing financial difficulties, the strong economies tend to exercise equality in various sectors such as education, clean water, and healthcare. Supporting education and healthcare programs may boost literacy and health levels thus enhancing harmony in global development and reduces diseases and infections which may perhaps spread to the rich countries if proper treatment is not taken. Even for countries that do not need aid ‘at the end of the day, it is a matter of life and death’. On the other hand, giving an aid may not be the best thing to do to underdeveloped countries because of several negative effects and intentions it has on the underdeveloped nations.

Theories of Nationalism and Ethnicity Essay Example | Topics and Well Written Essays - 3750 words

Theories of Nationalism and Ethnicity - Essay Example This is what they call the â€Å"Toyota Way†. Whatever characteristics it may carry, it must be systemic, truly lasting and valuable to them. Along this line, the main concern of this paper is the Japanese ethnicity prominent in the Japanese-based Toyota Motor Corporation (TMC). The intended framework is to scrutinize the uniqueness of the much researched management style_ the â€Å"Toyota Way† at the same time determine which sociological perspectives and paradigms that would apply to the characteristics of Toyota’s Japanese ethnicity as well as determine how it has given great impact to the success of TMC. This paper seeks to draw some answers to questions like has Japanese ethnicity posed more of a problem or an advantage to TMC? What techniques does TMC use on its people to be able to build and attain such reputation which won the confidence of the public to patronize TMC’s quality-made vehicles and services within a Western-dominated work area? What i s this Toyota Way? How does Japanese ethnicity affect the quality performance of TMC? This academic exercise would attempt to relate selected socio-ethnical principles to the established ethos or principles used by TMC as well as possibly draw out some answers whether these principles overlap, contradict or complement each other? It is then within these parameters that the discussion on this paper will revolve. On the other hand, the limitation of this paper will only be on the time frame used to feature actual conditions of TMC as this paper uses data and time series, specifically a year before to date or prior to the March 11, 2011 tsunami disaster and nuclear meltdown. Keywords: Toyota Way, Ethnicity, Ethnocentrism, Corporate culture Toyota Motor Corporation’s Domain Before interpolating the sociological perspectives of ethnicity to TMC’s management principles and to understand better the subject understudy, it is important to have knowledge first of Toyota Motor Co rporation, its corporate philosophy, values, vision, and how it operates. TMC’s domain belongs to the automotive industry and thus, its main product is the automobile. However, â€Å"TMC today has expanded its business to other non-automotive related business activities to include: community livelihood support, education, financial services, among others.

TMC, within its domain, has gained public confidence in the quality of its luxurious, economical and environmenta l-friendly vehicles and other hi-tech products it produced. It has also expanded to venture on enhanced advanced technology products like robotics, prototyped environment-friendly electric cabs; spearheaded activities that lessen carbon emission in the environment and in its other involvement related to its aspiration to actualize its corporate social responsibility. Not to forget, TMC has expanded also its non-automotive activities like community education and livelihood support packages as

In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot Essay Example for Free

In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot Essay In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot. In a modern context, are they still plausible figures? So witherd and so wild in their attire, that look not like thinhabitants othearth, and yet are ont? This description of the three weird sisters given by Banquo on first setting eyes on them creates an illusion of hell like hags; decayed and disfigured creatures. They are unnatural: they seem to be women but are not. It is Banquo who thinks they are evil: What! Can the devil speak true? Macbeth does not. Macbeth is intrigued by the sisters and later tells Lady Macbeth that he burned in desire to question them further. Macbeth asks the witches to stay showing he is interested in their predictions; Stay, you imperfect speakers, tell me more. The sisters speak dangerous thoughts, the same perhaps already plaguing his mind. If their predictions were already thoughts in the back of Macbeths mind, then the sisters lack power over him at this point. By examining the first conversation he has with Lady Macbeth on first returning home from battle, And when goes hence, tomorrow as he purposes this could be seen as evidence of couple having discussed the downfall of Duncan on an earlier date. If this is true then the sisters could be seen as mere triggers; they release the fiery evil within Macbeth. The fact that the sisters are in the first scene of the play confirms that they are important characters and from what they say, When the hurlyburlys done, when the battles lost and won gives the impression they know what is going to pass in the rest of the play. They meet in foul weather and talk of thunder, lightening and the fog and filthy air, giving the audience a first impression that Macbeth is a dark, dangerous play in which the theme of evil is central. They embody a malign and demonic intelligence. Their information does tempt Macbeth-but it is crucial to remember: they do not invite him to murder Duncan or even suggest a thing. Information is morally neutral until human beings begin to interpret it. The three hags prophecy that Macbeth will be king, they make no inclination whatsoever how he will come about this regal title. A lingering question still remains; had Macbeth given thought to killing Duncan before, and if the sisters had not made their prophecy, would Macbeth have murdered Duncan that night at the castle? In fact this is an unanswerable question but at the same time also very crucial. For if the answer is yes, the sisters would no longer be integral to the plot but be there just for the means of a supernatural subplot. On the other hand taking it as is given in the play, the implications of this are that Macbeth relies wholly on the sisters to spur him on. Macbeth is not a fool he realises that the prophecies cannot be ill, cannot be good and the forecasts of the future must come at a cost. Later on though, Macbeth no doubt driven by the success of his murdering of Duncan, seems to forget the sisters haunt that none of woman born shall harm Macbeth and the movement of Birnam Wood. Banquos warning to Macbeth concerning the instruments of darkness might also be seen as prophetical; Macbeth is betrayed as a result of believing these truths, and he comes to realise this in his final confrontation with Macduff. As the play goes on Macbeth is mixing his conscious life with his subconscious and the weird sisters become like a drug for him; the more you get, the better you feel, the more you want. The weird sisters prophecies draw out the evil within Macbeth; everyone has the basis to be truly wicked but not all of us have the trigger to pull it off, most of us are too full of the milk of human kindness. Regarding Macbeth, the weird sisters were his trigger. The evil does not come from anywhere else other than human nature. The sisters have not completely managed to corrupt Macbeth though. Both before and after Duncans murder Macbeth shows signs that his own natural feelings are still present in his character and that the witches do not have total power over him. He is foul for the things that he has done but is somewhat fair as he still has a natural human conscience. Before the murder Macbeth thinks that it would be cruel to kill innocent Duncan: Besides, this Duncan hath borne his faculties so meek, Had I but died an hour before this chance I had lived a blessed time. His feelings about Duncans murder are very similar to those about Banquos murder although he only acted out the first himself. He is sick with worry and guilt about Banquos murder, so much so he is turned to near madness by the bloody ghost of Banquo haunting him. On stage, Shakespeare sought to make the Witches actable and recognisable to his audience.In Britain we either rationalise Witchcraft or mock it and we have the added problem of an audience having seen Macbeth a countless number of times, often in very unconvincing renditions of Double, double toil and trouble it has even become some what of a comic joke book. With hooked nosed women dressed in black with pointed hats chanting round a cauldron; not quite a depiction of three terrifying, blood curdling, residents of hell. Shakespeare himself had to make adjustments to keep up with stage fashion. Originally he had three devils in place of the weird sisters, but the theatrical currency of devils was already starting to devalue through overuse, and they were more likely to induce laughter than fear. James I who was on the throne when Macbeth was written, famously believed in witches, he even wrote the novel, Daemonologie on the subject. Yet, during the lifetime of the king, attitudes to stage witches shifted and they started down the same comic route as the devils before them. This might be why no one in the text of Macbeth uses the word witch. When Shakespeare wrote Macbeth, weird characters were deemed capable of prophecy. Macbeth makes the association when he asks why the sisters stop our way, with such prophetic greeting. The modern mind, though, hear the modern denotation of weird, which incidentally, is used to describe those bearded ladies who vanish into the air. Formerly, weird ladies; those who endowed prophetic powers, were presumed to have magical powers as well. Now, ladies who think they have magical powers are presumed to be weird or peculiar Therefore it is becoming increasingly more difficult to make a contemporary western materialistic audience believe in them. Directors struggle to think of new interpretations of how to represent them. Are they young or old, male or female, disfigured or beautiful? Or even to represent them with the appearance of normal human beings, for that in itself is probably the most frightening understanding. Robert Cohen, in his 1982 Colorado Shakespeare Festival production, cast three beautiful women as the witches. Dressed in topless gowns they seduced Macbeth into a life of crime and corruption; here the weird sisters were depicted as real women more psychic than supernatural. Perhaps they too like Macbeth had morality, but had all the goodness sucked away and the evil human nature was dragged out of them and they were left even more corrupt than Macbeth is, at least he has the next life; hell we assume, they have to spend eternity festering in this world. This of course would be going against Shakespeares description of them but in my opinion in order to create three plausible figures in a modern context it is essential to create three characters; if they do even have any character that will make todays critical and realistic mind really believe that they are looking upon true forces of evil, rather than three women in black cloaks chanting round a cauldron. Personally it would not be plausible in my mind that they would be able to take the evil out of a man, who could do such terrible deeds. Perhaps a modern interpretation might be that it is genetics which control the way people make decisions; for if a director were to stage a futuristic Macbeth with the weird sisters as genetic engineers controlling the future, this would gain the desired effect on the audience; pure fear. Also, at the same time keeping up with stage fashions, test tube babies; the idea of creating humans unnaturally. For all our scientific rationality, modern society still acknowledges that there are forces we cannot explain. Some people believe in supernatural phenomenon; ghosts witches, evil forces; others would explain everything as from within the human mind; for example Lady Macbeth who generates the evil is already within Macbeth, therefore are just plot devices, there to release it from him. Even though they cause no first hand evil themselves, they evil that they thus create by delivering their riddle like prophecies is integral to the tragedy of Macbeth and without them fair would not be foul and foul would not be fair.

Alien and Sedition Act :: essays research papers

You are back in the year 1798, the government has just passed a law saying what ever they do and create it will be the standard. You have no say or any comment on it, because frankly they just don’t care. You are now placed back in the year 2001, would it be possible to apply a law of such magnitude to our society today? I don’t think so. Our country is based upon individual rights, we are allowed to say what we feel, and do what we want. It is what has shaped our country into what it is today. The saying rubber makes things perfect is one such example. It is a pliable material and can be formed or molded into whatever shapes you need it be. Just as our nation is today, it is pliable to our society’s needs. The Alien and Sedition Act demolished this moral standard by passing 4 acts that deny the power of people.   Ã‚  Ã‚  Ã‚  Ã‚  The United States at this time was faced with such economic and political problems domestically. Such economic problems as a trade barrier created such turmoil. In the text it is described that Spain, England and France on conditions of trade by saying that â€Å"Immediately following the war, Britain, France, and Spain are all restricted from American trade with the colonial states.† Our nation was also faced with one such problem as debt. The wars and battles our great nation has gone through in the past has created such a debt at this point in time that is almost not comprehendible for any normal human. In order to regain a financial balance the federalist came up with 3 solutions. They created an executive cabinet made up of heads of departments and they created a Judiciary Act of 1789. The Judiciary Act allowed for laws to be declared unconstitutional and put power back at a National level instead of state.   Ã‚  Ã‚  Ã‚  Ã‚  Hamilton came up with 3 reports to also help out with the debt our nation was facing. His first report was upon Pubic Credit, it stated that the nation would consolidate the debt at a national and state level, paying off the debt in face value, and would shift the power to the National Government. In Hamilton’s second report, he continued to set apart and distinguish between lower class and the aristocracy of the nation. Hamilton accomplished his separation by instating the First Bank of the United States.
