Bananas Are Radioactive (So Are Many Ordinary Objects)

You may have read about everyday objects setting off radiation alarms at border crossings between the US and Canada and Mexico. Newsweek has an article describing how medical radiation treatments (e.g., bone scans) may lead to traveling delays when they trigger radiation sensors. When the sensors are tripped, border officials conduct more intensive inspections to make sure you arent carrying nuclear weapons. There are other ways to set off the alarms. Do you carry kitty litter in your car to help provide traction in icy weather or to absorb oil? Its slightly radioactive. Do you have tile or granite in your vehicle for a home improvement project? It has a relatively high radiation signature. Do you have a lot of bananas? They are also slightly radioactive. Key Takeaways: Bananas Are Radioactive Bananas are slightly radioactive due to the presence of a natural isotope of potassium. Potassium is a key mineral in the fruit.Many other common materials are also radioactive, including potatoes, bricks, and cat litter.For the most part, these substances do not present a health risk. However, they can set off radiation sensors at ports of entry and their radioactivity is detectable using a Geiger counter. Its pretty easy to understand why tile, granite, and kitty litter are radioactive. They contain low levels of minerals that naturally decay. Bananas are radioactive for a similar reason. The fruit contains high levels of potassium. Radioactive K-40 has an isotopic abundance of 0.01% and a half-life of 1.25 billion years. The average banana contains around 450 mg of potassium and will experience about 14 decays each second. Its no big deal. You already have potassium in your body, 0.01% as K-40. You are fine. Your body can handle low levels of radioactivity. The element is essential for proper nutrition. If you have a banana in your car for your lunch you arent going to set off a Geiger counter. If you carry a produce truck full of them, you might encounter some problems. Ditto for a truck of potatoes or potassium fertilizer.The point here is that radiation is all around you. If you do an internet search, youll note significant concern (panic?) over bananas being radioactive. Are they radioactive? Barely. If you set a banana on a detector you wont hear mad clicking. It wont glow in the dark when you turn out the lights. There is a perception that radiation is bad, bad, bad. Its just a part of life. Bricks are radioactive. Anything containing carbon (you) is slightly radioactive. Bananas are radioactive and its no big thing. Well... except maybe to Homeland Security.

Assignment on Linear Algebra

Question: Discuss about the Assignment on Linear Algebra. Answer: The problem: One of the most important application of Linear Algebra is calculating the voltage and currents in closed loop circuits, and this importance rises when calculating largely closed loops with a large number of electronic components. In electrical circuit analysis, a set of linear equations are used to analyze the direct flow of current (DC), and the coefficients of these equations are real because its direct current circuits. Also, the linear equations can be used to calculate the current and voltages in alternative closed loop electronic circuits but with real and imaginary coefficients for these linear equations [1]. This would save huge effort and a great amount of time for electronic circuit designers, especially when dealing with too complicated closed-loop circuits. Moreover, electronic circuit builders use various values of resistors in the circuit to get the ideal current flow for each loop by using electronic circuit simulation software. Alternatively, they also can use system linear equations to specify the current for each loop in the circuit by changing the coefficient values of the variables in the system linear equations. In this application, we will try to calculate the three currents running in the three loops which are very simple electronic circuit but could give a general idea in how to tackle large-scale circuits by following the same solution procedure. In the figure below we have three circuit loops and each loop will present a linear equation assuming that the three currents are running in each loop in clockwise direction. Solution In order to solve the problem of these electronic circuits, first I have to make linear equation from the given data. As per Kirchhoffs Voltage law. The sum of all voltage meeting in loop is equal to zero according this we will go loop by loop to frame it is linear equation. For Loop 1 5I1+10(I1-I2) +10+10(I1-I3)-10=0 For Loop 2 10I2+5+10(I2-I3)-10+10(I2-I1) =0 For Loop 3 10I2+5+10(I2-I3)-10+10(I2-I1) =0 If we simply the equation, we can see that it is just like linear equation in form f( x+y+z) = f(x) + f(y) + f(z) = c.f(x) where x, y, z are the variable and C =constant, in this condition we have to find x which is in the form current, Suppose it is I1, I2, I3. We have to frame the given coefficients in the form of linear algebra. For loop 1 25I1-10I2-10I3=0 For Loop 2 -10I1+30I2-10I3=5 For loop 3 -10I1-10I2+33I3=0 This is in the form of equation Ax=b Where, A = coefficient of the three currents for the three loops = b= the constant number after equality sign in our equations= x= the unknown three currents running the three loops= All the coefficients is framed in to solve this equation as a linear algebra, Putting all the values in mat lab, we can calculate the value of x i.e. all the current I1, I2, I3 by framing this into inverse of linear, matrix x =A-1*b Finally we get the result as given below x= Where I1 = 0.1541 Amp, I2 = 0.2599 Amp, and I3 = 0.1254 Amp Here we can see that what a linear equation can do in electronic circuits. We have taken the help of one computational advance techniques in engineering and that is MATLAB, The code of the MATLAB is given below clc; % constant number after the equality sign of the three simplified equation. b= [0;5;0]; % the coefficients of the currents for the three equations.

Othello by William Shakespeare

Introduction One of the reasons why William Shakespeare’s tragedy Othello never ceases to remain popular with the public is that the themes of motifs, contained in it, appear truly universal. In other words, while being exposed to the staging of this particular tragedy, viewers do recognize the essence of a variety of psychological anxieties, on the part of the characters, as such that relate to their own.Advertising We will write a custom term paper sample on Othello by William Shakespeare specifically for you for only $16.05 $11/page Learn More This explains why the staging of Othello can be well adapted to the realities of today’s living. In our paper, we will aim to explore the soundness of an earlier articulated thesis at length, while comparing/contrasting Shakespeare’s original play with one of its most recent cinematographic adaptations – Tim Nelson’s 2001 movie O. Analytical part Even though movie’s plot unravels amidst contemporary settings, with American typical high school serving as a background, director had deliberately strived for O to emanate as much of original tragedy’s spirit as possible. And, it has to be said that Nelson was able to succeed in it. The validity of this statement can illustrated by the very fact that the names of film’s characters phonetically resemble characters’ names in Shakespeare’s play – Odin/Othello, Iago/Hugo, Desi/Desdemona, Duke/Duke Goulding, etc. Just as it is being the case in Shakespeare’s Othello, the only black character (Odin) in the film appears to be everybody’s favorite – the man on a direct pathway towards gaining social prominence. Despite his blackness, which made him a visible minority in White suburbia’s high school, Odin had proven himself quite indispensible to school’s basketball team. In a similar manner with Shakespeare’s Othello, Odin had found him self fallen in love with white girl Desi – the daughter of school’s principal. Both lovers’ happiness was about to prove short-lived, however, as after having initially failed at revealing Odin as a rapist, his teammate Hugo designed a plan to expose Desi’s infidelity in Odin’s eyes. Such line of a plot, of course, closely resembles that of original Othello’s. Moreover, as it appears from the movie and the play, it is namely due to Iago and Hugo’s perverted sense of justice, that both characters wanted to cause harm to Othello/Desdemona and Odin/Desi – apparently, they both considered themselves being treated unfairly by the ‘cruel world’:Advertising Looking for term paper on art and design?

No way!† (00.08.27). Nevertheless, while being aware of the fact that Othello/Odin could not be challenged openly, Iago/Hugo decided to utilize a particularly sneaky method of destroying his happiness – planting the seed of jealousness in Odin’s heart. Just as it was the case with Iago in Shakespeare’s play, who prompted Cassio to initiate a drunken fight with Roderigo and to consequently lose respect in Othello’s eyes, Hugo encourages Odin’s best friend Michael to act in essentially the same way – to get drunk and to fall out of favor with Odin, as the result. Once, this has been accomplished, Iago/Hugo proceeded further with his devilish plan – he advices Michael/Cassio to socialize with Desdemona/Desi as something that would help him getting back on good terms with Othello/Odin. Simultaneously , Iago/Hugo encourages Othello/Odin to think of the fact that Desdemona/Desi befriended Cassio/Michael as the proof of her unfaithfulness. In other words, just as we have pointed out earlier, even watching the initial parts of Nelson’s movie leaves very little doubt as to the fact that the themes and motifs, contained in cinematic adaptation, closely match those contained in Shakespeare’s tragedy. Nevertheless, there is a striking difference between how Nelson and Shakespeare interpret the social implications of Hugo/Iago’s blackness. Whereas; in the original play the specifics of Othello’s racial affiliation do not imply him being subjected to white racism, in traditional sense of this word, in Nelson’s movie Odin is being shown as an individual who suffers a great deal from being looked upon by his even most open-minded classmates as someone who does not quite belong to their circle. There is a memorable scene in O, where Michael articulates his deed-seated racist attitude towards Odin with perfect clarity: â€Å"Hugo: What about Odin? Michael: What about him? He is a freaking loser. The ghetto just popped out of him† (01.05.51). Apparently, while adapting original tragedy’s motifs to the realities of today’s living in America, Nelson simply could not refrain from incorporating the theme of racism into the very core of movie’s plot.Advertising We will write a custom term paper sample on Othello by William Shakespeare specifically for you for only $16.05 $11/page Learn More This is exactly the reason why this theme, along with the theme of political correctness, is being even explored within the context of Odin indulging in intimate conversations with Desi: â€Å"Odin: See, I can say ‘nigger’ cause I’m a nigger. You can’t cause you ain’t’ (00.15.02). Unlike what it used to be the case with Othello, Odin never ceases to remain acutely self-aware of the color of his skin. Another difference between Shakespeare’s play and Nelson’s film is the fact that; whereas, in the play most characters are being represented as well-grown individuals, film’s characters are essentially teenagers. In its turn, this explains the lessened plausibility of film’s action, as compared to what it is being the case with original tragedy. After all, it was partially due to Othello’s rational realization of the fact that, after having been ‘betrayed’ by Desdemona, he will never be able to get married (because of his old age and ugliness), which filled his heart with anger and prompted him to kill her. Odin, on the other hand, did not have rational reasons to kill Desi – being the most popular person in the school; he would never have a problem falling in love with just about any other white girl. Given the fact that, as of today, more and more American teenagers tend to think of love as being synonymous to the notion of sex, it naturally predisposes them towards assessing the very concept of ‘romantic faithfulness’ as being quite irrelevant. Therefore, whatever emotionally intense the scene in which Odin strangles Desi to death might be, it can be the least referred to as utterly realistic. Conclusion As we have pointed out in Introduction, there are good reasons to consider Shakespeare’s Othello as cinematically adaptable dramaturgic piece. The watching of Nelson’s film substantiates the validity of this claim perfectly well. After all, for as long as the representatives of Homo Sapiens specie continue to remain highly social beings, they will never cease experiencing the whole range of Shakespearean emotions – love, hate, jealousy, revengefulness, etc. Therefore, despite film’s earlier mentioned shortcomings, it nevertheless can be best defined as utterly accurate in how it tackles the theme of Shakespearian tragi c love. We believe that the earlier provided line of argumentation, in defense of such an idea, is being full consistent with paper’s initial thesis – in his film, Nelson did in fact succeed with popularizing the theme of tragic love as such that represents a great philosophical value.
