Addition of NaoH solution to Cu (NO3)2 gave a dark blue solution. After boiling the Solution gotten above, I sieved out the water and had CuO(s) left in the Beaker. The addition of HCl (drop wise) to CuO gave a yellowish green solution. When NH4OH solution was added it gave a yellowish green solution. I added 15ml of 1. m H2SO4 to yellowish green solution co I suspect the copper complex to be [Cu (H2O) 6]2+, since it gave a blue-green solution. When zinc dust was added to The solution a shiny reddish brown metal was formed. Discussion It is observed that copper was conserved throughout the experiment. And despite The conservation of copper in the reaction, the percentage recovery of copper is less than 100%. i had 80% of copper recovered from Cu (NO3)2. After pouring out the supernatant some CuO clung to the wall of the beaker. Therefore, the HCl did not dissolve all of the CuO. This unreacted CuO causes a decrease in the mass of Cu recovered. Also, I forgot to scrunch the copper formed before drying. The clumps of copper might contain some water which increases its mass when weighed. It is necessary to synthesize the various compounds one after the other in order to recover copper metal because, it is not possible to get copper metal because it is not possible to get copper directly from Cu (NO3)2. all these phases are needed to be passed through. When zinc is added a zinc hexaquo complex is formed from the bonding of Zn2+ with six molecules of water. The addition of H2SO4 causes the Cu2+ from Cu(OH)2 to combine with water molecules to form [Cu(H2O)6]2+. The Cu(OH)2 is gotten from reaction of CuCl2 with NH3. The percent yield depends on whether certain reactions were completed or not. my percent yield 80% is affected by incomplete reaction of CuO with HCl. During the decomposition of Cu (OH) 2, some Cu might have been lost in heat form. Also when transferring the copper from the Buchner funnels into the weighing bottle, some copper metal were stuck to the funnel. This would also decrease the percent yield of copper gotten. Conclusion Given the concentration of Cu (NO3)2 and volume as 10. 0ml, the percent recovery of copper gotten from synthesis of copper compounds is 80%.

Nethercott and M. Evelynn Walton Department of Physics, University of Utah, Salt Lake City, 84112, UT, USA (Dated: March 6, 2013) Using a simple pendulum the acceleration due to gravity in Salt Lake City, Utah, USA was found to be (9. 8 +/- . 1) m/s2 . The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported by the data using a linear ? t with chi-squared value: 0. 7429 and an r-square value: 0. 99988. This experimental value for gravity agrees well with and is within one standard deviation of the accepted value for this location. I. INTRODUCTION The study of the motion of the simple pendulum provided valuable insights into the gravitational force acting on the students at the University of Utah. The experiment was of value since the gravitational force is one all people continuously exp erience and the collection and analysis of data proved to be a rewarding learning experience in error analysis. Furthermore, this experiment tested a mathematical model for the value of gravity that that makes use of the small-angle approximation and the proportional relationship between the square of the period of oscillations to the length of the pendulum. Sources of error for this procedure included precision in both length and time measurement tools, reaction time of the stopwatch holder, and the accuracy of the stopwatch with respect to the lab atomic clock. The ? nal result of g takes into account the correction for the error introduced using the approximation. There are opportunities to correct for the e? cts of mass distribution, air buoyancy and damping, and string stretching[1]. Our results do not take these e? ects into account at this time. A. Theoretical Introduction The general form of Newton’s Law of Universal Gravitation can be used to ? nd the force between any two bodies. FG = ? G mME ? 2 r RE (1) 2 On earth this equation can be simpli? ed to F = ? mg? with the value r GME 2 RE taken to be the constant g. The value of gravity in Salt Lake City (elev. 1320 m) according to this model is: 9. 81792 m/s2 [3][4][5]. The simple pendulum provides a way to repeatedly measure the value of g.

F = ma = mgsin? can be written in di? erential form ? g ?=0 L The solution to this di? erential equation relies on the small angle approximation sin? ?: (2) (3) ? for small ?(t) = ? 0 cos( g ) L (4) 3 The Taylor expansion ?(t) ?o [1 ? gt2 g 2 t2 ] + 2L 4! L2 (5) allows us to take the ? dependence out of the equation of motion. Taking the second derivative of the approximation gives the following: g ? ? = 0 L (6) 0 g g g g + ? = 0 =? ?0 = ? L L L L g L, (7) 4? 2 T2 ? We know from the ? rst derivative ? = ? so it follows that since ? 2 = = g L ?0 . g 4? 2 =? 2 L T (8) From the initial conditions it is also clear that the initial amplitude ? is equal to ? 0 and so the linear relationship between length L and period T 2 can be expressed as T2 = . 4? 2 L g (9) Using the small angle approximation introduces a small systematic error in the period of oscillation, T. Fo r instance the maximum amplitude angle ? for a 1 percent error is . 398 radians or 22. 8 degrees; to reduce the error to 0. 1 percent the angle must be reduced to . 126 radians or 7. 2 degrees. This experiment used an angle of about 10 degrees and that introduced an error of 0. percent. The calculations for the systematic error are found in the Appendix. II. EXPERIMENTAL PROCEDURE A. Setup As seen in Figure 2, the pendulum apparatus was set up using a round metal bob with a hook attached to a string. The string passed through a hole in an aluminum bar, which was attached to 4 the wall. The length of the string could be adjusted, and the precise point of oscillation was ? xed by a screw, which also connected a protractor to the aluminum bar. FIG. 2: Experiment setup. Length measurements for the pendulum were taken using a meter stick and caliper. The caliper was used to measure the diameter of the bob, having an uncertainty of 0. 01cm. The total length was measured by holding the meter stick up against the aluminum bar, and measuring from the pivot point to the bottom of the bob. The bottom was determined by holding a ruler horizontally against the bottom of the bob. The meter stick measurements had an uncertainty of 0. 2cm. Time measurements were made using a stopwatch. For measuring the ? rst swing the starting time was determined by holding the bob in one hand and the stopwatch in the other and simultaneously releasing the bob and pushing Start. The stopping point, and starting point for the second oscillation, was determined by watching the bob and pushing Stop/Start when the bob appeared to reach the top of the swing and stop. The precision of the stopwatch was compared with an atomic clock by measuring several one second intervals. The precision of the time measurements were also a? ected by reaction time and perception of starting and stopping points of the person taking the measurements. Time measurements were taken by the same person to keep the uncertainty in reaction time consistent. 5 B. Procedure To determine which measurements weremost reliable, data was taken for the period of the ? rst oscillation, second oscillation, and twenty oscillations (omitting the ? rst) at a set length of 20. 098 cm. The length was then adjusted to 65. 5647 cm, and the same measurements were taken. To see the limits of the small angle approximation measurements of 20 oscillations (omitting the ? rst) at a ? xed length of 60. 1605 cm were taken by beginning the swing at angles of 5, 10, 20, and 40 degrees. Measurements were then taken for 20 oscillations (omitting the ? rst) for lengths of 20. 098, 26. 898, 32. 898, 60. 1605, 65. 6467, 74. 648, 89. 848, 104. 548, 116. 498, and 129. 898 cm at a starting angle of about 10 degrees. III. RESULTS The result for g obtained from both measured values of L and T 2 from equation 9 as well as from the slope in the Linear Fit model (Figure 4) agree very well with accepted results for g. The precision could be improved by corrections for e? ects of mass distrib ution, air buoyancy and damping, and string stretching[1].

DISCUSSION By measuring 20 oscillations the average period is determined by dividing by 20 and this helps reduce the error since the error propagation will provide an uncertainty in the period that is the uncertainty in the time measurement divided bytwenty. From Table 1 and Figure 3 the limits of the small angle approximation are shown. Between 10 and 20 degrees the theoretical model begins to breakdown and the measured period deviates from the theoretical value. Measurements taken at less than 10 degrees will be more accurate for the small angle approximation model that was used. Two methods were used to calculate a value of g from the data. The ? rst method used to calculate a value of g from the measurements taken is making the calculation from each of the 6 1. 62 1. 60 T (sec) 1. 58 1. 56 1. 54 0 5 10 15 20 25 30 35 40 45 Angle (degrees) FIG. 3: Period dependence on angle as ? increases from 3-40 degrees.

The slope of this line was used to calculate g. en di? erent lengths, using the measurements shown inTable 7 of 20 oscillations at the di? erent lengths, and taking the average. The calculated average g was (9. 7 + / ? 0. 1) m/s2 . The second method used was applying a linear least squares ? t to the values of length and the 7 accompanying T 2 . Figure 4 shows this method and gives the values for the ? t parameters. The value of g is determined by using the slope of the line and gave a value of g to be (9. 8 + / ? 0. 1) m/s2 . Figure 5 shows that data has a random pattern and all of the error bars go through zero, which means that the data is a good ? for a linear model. 0. 10 0. 05 Residual T 2 0. 00 -0. 05 -0. 10 0. 2 0. 4 0. 6 0. 8 1. 0 1. 2 1. 4 Independent Variable FIG. 5: Random pattern of Residual T 2 . As discussed in the theoretical introduction, a value of g 9. 81792 m/s2 can be calculated using G, ME , and RE . The value of g varies depending on location due to several factors including the non-sphericity of the earth, and varying density. A more accurate value of g in Salt Lake City, Utah can be calculated by taking into account these e? ects. The National Geodetic Survey website, which interpolates the value of g at a speci? latitude, longitude and elevation from observed gravity data in the National Geodetic Survey’s Integrated Data Base, was used to determine an accepted value of g for Sal t Lake City, Utah, for which to compare the calculated results[7][8][6]. The accepted value for g in Salt Lake City, Utah is (9. 79787 + / ? 0. 00002) m/s2 . Comparing the two methods used to calculate g shows that the least squares linear ? t provided a value of g that is closer to the theoretical[3][4][5] and accepted[7][8][6] values of g. The calculation of g supports the small angle approximation model that was used. The linear relationship to length and period squared provided by the approximation gave a way of employing a least squares linear ? t to the data to determine a value of g. Since the calculated value was 8 within one standard deviation from the theoretical value, the model was supported. V. CONCLUSION The small angle approximation model, which gives g as being proportional to T 2 and L, was supported by the data taken using a simple pendulum. The residual of the data showed that it was a good ? t for a linear model, and the least squares linear ? t of the data had ? t parameters of chi-squared: 0. 7429 and an r-square value: 0. 99988. The value of g taken from the slope of the least squares linear ? t provided a value of g: (9. 8 + / ? 0. 1) m/s2 , which is within one standard deviation of the accepted value of gravity in Salt Lake City: 9. 79787 m/s2 [6]. The experiment was a good way of testing the small angle approximation because the period measured using di? erent starting angle s was consistent for angles less than 10 degrees. Using the small angle approximation the relationship between period squared and length was linear so a least squares linear ? t could be utilized to calculate g. The value of g calulated using the least squares linear ? t could then be compared to the accepted value of g for the location, thus verifying the model that was employed. [1] R. A. Nelson, M. G.

Time The sources of error introduced in this experiment came from the tools we used to measure length: calipers for the bob and a meter stick for the string length as well as the stop watch used to time each period of oscillation. Measuring the period had several sources of error including precision, the atomic clock benchmark, the reaction time of the experimentor, and the statistical error which was the standard deviation from the measurements taken. On the whole, the relative error in T was greater so that was the error used in the linear ? t analysis. ?T = 1 20 (? Treaction )2 + (? Tatomic )2 + (? Tprecision )2 + (? Tstatistical )2 (10) Equation 10 also takes into account the error propagation in taking the time period for twenty oscillations. This ? T is the random error; to account for the systematic error introduced by using the small angle approximation the complete solution for the period of oscillation is as follows [2]: 1 ? max 9 ? max T (? max ) = T0 + T0 [ sin2 ( ) + sin4 ( )] 4 2 64 2 (11) To ? nd the percent error introduced by the angle used in the experiment the solution in equation 11 was rearranged to give: T (? max ) ? To 1 ? max 9 ? max = sin2 ( ) + sin4 ( ) T0 4 2 64 2 (12) The angle used in this experiment was 10 degrees. Plugging that value into the right side of equation twelve gives a value of . 002967. It follows that T0 = T (? max ) 1. 002967 (13) Each of our measured values of T was corrected by this factor. To get the error for T 2 : ? T 2 = T ? T The results are found in Table 7. These values were plotted in ? gures 4 and 5. (14) 10 C. Gravity The errors in the calculations for g were determined di? erently for the two methods. The uncertainty in the least square ? t was calculated from the slope and uncertainty of the slope (see Figure 4). ?g = The calculations of g from L and T 2 used: ? g = g ( These values are found in Table 8. 4? 2 ? m m2 (15) ?L 2 ?

An atmosphere of helium would cause an organ pipe to have a higher pitch because the speed of sound is taster in helium, but since the pitch tot a tuning fork has a set frequency, the pitch will not change, 3. If you measure an interval of S seconds between seeing a lighting flash and hearing the thunder with the temperature of air being ICC, the lightning was 1715 meters away, x=mm 4.

Wavelengths may be found by measuring the difference between two successive tube lengths at which resonance occurs and will be half the wavelength. The original hypothesis for this experiment was that the speed of the sound will be greater due to the enrapture of the air being higher. In the experiment, when the water was lowered to different heights which in turn caused a change in length of the air columns. Which then allowed the tuning fork to resonant.

Lab Report Essay Example Lab Report Paper The arm may be a bent portion of the shaft, or a separate arm attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod. The end of the rod attached to the crank moves in a circular motion, while the other end is usually constrained to move in a linear sliding motion. In a reciprocating piston engine, the connecting rod connects the piston to the crank or crankshaft. Together with the crank, they form a simple mechanism that converts linear motion into rotating motion. Connecting rods may also convert rotating motion into linear motion. Historically, before the development of engines, they were first used in this way. In this laboratory we will investigate the kinematics of some simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration or kinematical restricted motions, which will discover. An adjustable slider- crank apparatus and a computer simulation will show you some effects of changing the proportions of the slider-crank mechanism on piston velocity and acceleration. Other linkages and cam mechanisms may also be used for linear- rotary motion conversion and some of these will be included in the lab Abstract The distance between the piston and the centre of the crank is controlled by the triangle formed by the crank, the connecting rod and the line from the piston to the centre of the crank, as shown in [ Figure 1 1.

From this geometry, the distance s is given by [1]: The rightmost position of P occurs when the crank and connecting rod are in line along the axis at P and the distance from O to P is I + r. Since the distance measured in the experiment uses this position as the reference location, the distance measured is given by: This means that x is a function of the crank angle O and that the relationship is not linear. Figure 1 Geometry of Crank and Connecting Rod Mechanism Procedure 1 . )III of equipments for experiment of slider crank are set in good condition. 2. )Before taking readings,we turned the crank slowly and watched the movement of the piston to make sure it moves in the correct direction 3. ) The angle of the circle, is twisted at degrees and a resulting distance that the piston moves, q is measured. The position of sliding block/slider, x is calculated 4. ) The procedures number 3 and number 4 are repeated with an increasing angle of 5 degrees until the angle of circle reaches 3600 5. ) The graph of the position of slider, against angles of circle, is plotted. Apparatus Crank and connecting rod assembly Conclusion From the experiment we can conclude that the motion of the piston will gradually approach simple harmonic motion in increasing value of connecting rod and crank ratio. Even though that is the case in this experiment we did not really get the graph as said in theory but it is almost the same. I believe that we had done something wrong while doing the experiment. The graph plotted can be shown that almost all the graphs tend to move to simple harmonic motion. The experiment was a simple one but it really needs a lot of time to take the eating.

Mycobacterium has a thick, waxy wall that makes penetration by stains extremely difficult so the acid fast stain is used because once the primary stain sets it cannot be removed with acid alcohol. This stain is a diagnostic value in identifying these organisms. MATERIALS: * Bunsen burner * Hot plate * Inoculating loop * Glass slides * Bibulous paper * Lens paper * Staining tray * Microscope METHODS: 1. Prepared a bacterial smear of M. Schematic, S. Erasures, ; a mixture of M. Schematic ; S. Erasures 2. Allowed 3 bacterial slides to air dry ; then heat fixed over Bunsen burner 8 times. . Set up for staining over the beaker on hot plate, flooded smears with primary stain-crystal fuchsia and steamed for 8 minutes. 4. Rinsed slides with water 5. Decolonize slides with acid alcohol until it runs clear with a slight red color. 6. Rinsed with water 7. Countersigned with methyl blue for 2 minutes 8. Rinsed slides with water. 9. Blot dry using bibulous paper and examine under oil immersion * Mycobacterium Schematic * S. Erasures * A mixture of S. Erasures ; M. Schematic RESULTS AND DATA USED: 1. M. Schematic, a bacilli bacteria that colored pink resulting in acid fast. 2. S. Urges, a Cisco bacteria that colored blue resulting in non acid fast. 3. M. Schematic ; S. Erasures resulted in both acid fast ; non acid fast. CONCLUSION The conclusion to the acid fast stain is that S. Erasures lacks a cellular wax wall causing the primary stain to be easily removed during decentralization, causing it to pick up the countersink-methyl blue. This results in a non acid fast reaction, meaning it is not in the genus Mycobacterium. M. Schematic has a cellular wax wall causing the primary stain to set in and not be decolonize; this results in an acid fast reaction meaning it is in the genus Mycobacterium. REVIEW QUESTIONS Question 1: Why must heat or a surface-active agent be used with application of the primary stain during acid-fast staining? Answer: It reduces surface tension between the cell wall of the embarcadero and the stain. Source: Microbiology page 79 Question 2: Why is acid-alcohol rather than ethyl alcohol used as a decontrolling agent? Answer: Acid-fast cells will be resistant to decentralization since the primary stain is more soluble in the cellular waxes than in the decontrolling agent. Ethyl alcohol would make the acid fast cells non-resistant to the decentralization. Source: Microbiology A Laboratory Manual 4th Edition/ James G. Cappuccino, Natalie Sherman/ 2008/ page 79 Question 3: What is the specific diagnostic value of this staining procedure? Answer: Acid-fasting staining represents bacteria that is pathogenic to humans Question 4: Why is the application of heat or a surface-active agent not required during the application of the counter stain in acid-fast staining? Answer: The counter stain methyl blue is only needed to give the stain its color.

Microscopic examination f the childs sputum reveals no acid-fast rods. However, examination of gastric washings reveals the presence of both acid-fast and non-acid fast bacilli. Do you think the child has active tuberculosis? Explain. Answer: Yes, the child may have active tuberculosis. Although, acid-fast microorganisms are not easily removed and non-acid fast are. Tuberculosis represents bacteria that are pathogenic to humans, the stain is of diagnostic value identifying these organisms. Source: Microbiology A Laboratory Manual 4th Edition/ James G. Cappuccino, Natalie Sherman/ 2008/page 79 LAB EXPERIMENT NUMBER 13 The purpose of this experiment is to identify the difference between the bacterial spore and vegetative cell forms. The vegetative cells are highly resistant, metabolically inactive cell types. The endoscope is released from the degenerating vegetative cell and becomes an independent cell. MATERIALS: * hot plate * staining tray * inoculating loop * glass slides * bibulous paper * lens paper * microscope 1 . The spore stain (Schaeffer-Fulton Method) is performed on a microscopic slide by making an individual smear of the bacteria on slide and heat fixing until dry. 2. Flood the smears with malachite green and place on top of a beaker of warm eater on a hot plate, allowing it to steam for 5 minutes. 3. Remove the slide and rinse with water. 4. Add counter stain seafaring for 1 minute then rinse again with water and blot dry with bibulous paper. MICROORGANISMS USED: * S. Erasures * S. Erasures B. Rues mix RESULTS/DATA USED 1. B. Cereus- green spores, pink vegetative cells, endoscope located in center of cell 2. B. Cereus S. Erasures- green spores, pink vegetative cells, endoscope located in center of cell CONCLUSION: An endoscope is a special type of dormant cell that requires heat to uptake the primary stain. To make endoscopes readily noticeable, a spore stain can be used. In using a microscope, under oil immersion, you will be able to identify the color of the spores, color of the vegetative cells and be able to locate the endoscope in certain bacteria like S. Erasures and B. Cereus. Question 1: Why is heat necessary in spore staining? Answer: The heat dries the dye into the vegetative cell of the spore. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 Question 2: Explain the function of water in spore staining. Answer: The water removes the excess primary stain, while the spores remain green the water nines the vegetative cells that are now colorless. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 Question 3: Assume that during the performance of this exercise you made several errors in your spore- staining procedure. In each of the following cases, indicate how your microscopic observations WOUld differ from those observed when the slides were prepared correctly. Answer: a. ) You used acid-alcohol as the decontrolling agent. The alcohol would wash out all coloring from the bacteria. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 5 b. ) You used seafaring as the primary stain and malachite green as the countersink. Seafaring will absorb to vegetative cells and not endoscopes since you need heat for endoscopes to form and malachite green will not absorb without heat but it will to vegetative cells. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 85 c. ) You did not apply heat during the application of the primary stain. Without heat, the endoscopes will not form and it will not penetrate the spore to color the vegetative cell. Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 5 Question 4: Explain the medical significance of a capsule. Answer: The capsule protects bacteria against the normal phagocyte activities of the host cells. Source: Microbiology Lab Manual, 8th edition, Cappuccino Sherman, p. 7 Question 5: Explain the function of copper sulfate in this procedure. Answer: It is used as a decontrolling agent rather than water, washes the purple primary stain out of the capsular material without removing the stain bound to the cell wall, the capsule absorbs the copper sulfate and will appear blue. Cappuccino Sherman, p. 88 LAB EXPERIMENT NUMBER AAA The purpose of this experiment is to identify the best chemotherapeutic agents used for infe ctious diseases. S. Erasures is the infectious disease used for this experiment. MATERIALS: * Sense-disc dispensers or forceps * sterile cotton swabs * glassware marking pencil * millimeter ruler Using the Kirby-Bauer antibiotic sensitivity test method is used. This method Uses an Antibiotic Sense-disc dispenser, which placed six different types of antibiotics on an Mueller-Hint agar plate, infected with S. Erasures. The antibiotics are in the form of small, round disc, approximately mm in diameter. The antibiotics are placed evenly away from each other on the S. Erasures infected Mueller-Hint agar plate and incubated at 37 degrees Celsius for up to 48 hours. After the completed incubation time, any area surrounding the antibiotic disc which shows a clearing or an area of inhibition is then measured. Measurements are taken from the diameter of each antibiotic area of inhibition. This measurement will determine which of the antibiotics is best to be used against the specific organism. (In this case, S. Erasures) MICROORGANISMS USED: S. Erasures ANTIBIOTICS USED: Autocratic Erythrocyte Cylindrical Geocentric Fancying Linemen A chart showing the measurements of each antibiotic is used to determine its effectiveness. The three different types of ranges are: Resistant (Least useful) Intermediate (Medium useful) Susceptible (Most useful) The following results are: Zone Size Autocratic mm (Susceptible) Erythrocyte mm (Intermediate) Cylindrical mm (Intermediate) Geocentric mm (Susceptible) Fancying 13 mm (Susceptible) Linemen 21 mm (Susceptible) CONCLUSION: 4 of the 6 antibiotics above can be effectively used against inhibiting this organism (S. Erasures). This information would be passed on to the provider of the infected patient, so the patient can be given the antibiotic chosen by their provider and recover from this infection. LAB EXPERIMENT NUMBER BOB The purpose of this experiment is to evaluate the effectiveness of antiseptic agents against selected test organisms. MATERIALS: The materials used are five Traipses soy agar plates. 24-48 hours Triplicate soy broth cultures of E. Coli, B. Cereus, S. Erasures and M. Specialist. The microorganisms used were E. Coli, B. Cereus, S. Erasures and M. Specialist. The data collected in this experiment shows chlorine bleach having the broadest anger of microbial activity because it has the strongest ingredients. Tincture of iodine and hydrogen peroxide seems to have the narrowest range because the contents arent as strong. CONCLUSION: The Agar Plate-Sensitivity Method shows the effectiveness of antiseptic agents against selected test organisms. The antiseptic exhibited microbial activity against each microorganism. Question 1: Evaluate the effectiveness of a disinfectant with a phenol coefficient of 40. Answer: A disinfectant with a phenol coefficient of 40 indicates the chemical agent being more effective than the phenol. Source: Microbiology A Laboratory Manual 4th Edition/ James G.

Dorian Gray and Corruption Essay Example

Dorian Gray and Corruption Essay Example Dorian Gray and Corruption Paper Dorian Gray and Corruption Paper very few people are worthy, etc. What is more, Basil Hallways is also one of the reasons why Dorian becomes corrupted as he is the one ho painted and therefore revealed to Dorian his own beauty through his portrait. The first visible instance of Doormans corruption happens after he rejects Sibyl Vane. When Dorian comes home and sees his portrait, the painted image now has an expression of cruelty on its face. This terrifies Dorian and convinces him to correct his cruelty towards Sibyl and be a better person in general. However the arrival of Lord Henry with his news of Sibyls death and his poisonous world makes Dorian changes his mind. He decides to experience Eternal youth, infinite passion, pleasures subtle ND secret, wild Joys and wilder sins ( ) and to let his portrait bear the burden of his shame. This was only the beginning of his plummet into the dark side Then Lord Henrys bad influence is at Its peak when he offers Dorian the yellow book. This book, which is not properly named, is about a young Parisian who dedicates his life to vices and sins. Dorian finds himself so fascinated by It that he decides to make his own life similar to the mall characters one: for years, Dorian Gray could not free himself from the influence of this book. he never sought to free himself. Then his Innocence disappears for good. Later In the novel, Dorian will Implore Lord Henry not to lend the book to anyone else because It poisoned him and It does harm. Indeed, after reading this book Dorian corrupts young gentlemen and brings shame on them and their families. There Is a lapse In time of eighteen years In the novel after Sibyl death where its hinted that he did various other bad deeds that cause several his youthful beauty. One night, Basil seeks Dorian out to confront him about his bad petition, they argue and Dorian decides to show Basil exactly how true the rumors are by showing him his hidden portrait after Basil has witnessed in horror the changes made to his painting, Dorian slit his throat in rage and resentment. He then blackmails an ex-friend doctor to dispose of the body which will drive the friend to suicide later in the novel. Doormans guilt pushes him after that to go to an opium den where he meets James Vane who will end up dead after following him to a hunt and accidentally getting shot. In the end, Dorian too frightened and repulsed by the vying proof of the taint of his soul stab his portrait and accidentally kills himself. The last stage of corruption is obvious at the end, all control is lost. He murders Basil, and then tries to kill his conscience, which he identifies with his picture. Instead, he himself dies and become completely evil. Dorian corrupted behavior and way of thinking is the cause of death of his entourage. Everyone who is close with him becomes corrupted even Lord Henrys sister, Lady Condoled who after meeting with him isnt able to live with her children anymore. Doormans sins are reflected in his stricture which he hides from the world as hes afraid of people guessing his true nature. Furthermore, the city of London also plays a part in Dorian Grays corruption. London, like Dorian Gray had two different aspects: the East and the West, the good side and the evil one. Although East London was dedicated to sins like prostitution and drugs (opium), West London represented the aristocracy. As the novel progresses Dorian is drawn by the East: muff have been seen creeping at dawn out of dreadful houses and slinking in disguise into the foulest dens in London. Is he really so innocent? At the beginning of the novel, Dorian Gray is depicted like an innocent young man. In the 1st chapter Basil introduces Dorian Gray like a piece of art: Unconsciously he defines for me the lines of a French school ( ) the harmony of soul and body. So before Lord Henrys corruption, Dorian Gray remains as pure as his beauty. However, the painter who is explaining to Lord Henry Watson, one of his best friends, how Dorian influences his art, also uses these words to describe Dorian: Now and then, however, he is horribly thoughtless, and seems to take a real delight in giving me main (chapter 1). At the beginning of the novel, Dorian even though he hasnt committed any sins, is described as someone who hurt people without being aware of it. Furthermore, the words used to describe Dorian Gray in the 2nd chapter usually refer to children: swinging wound on the music-stool in a willful, petulant manner, a faint blush colored his cheeks for a moment, a funny look of penitence. , cried, a little moue of discontent. It can be argued that Dorian Gray is innocent like a child is : children are usually considered innocent and naive but they can also be cruel, elfish or insensitive sometimes. What is more we learn Dorian Grays background in chapter Ill, and it appears to be very dark. Indeed, his mother had an affair with a man of inferior status, at the end of which the man is murdered on her fathers orders. Then Doormans mother died giving birth. Those sorts of events usually play a part in a mans mind and could be the origin of his taste for corruption he ignored first. Last but not least, Dorian Gray is not that innocent because he always had the opportunity to choose between what his good according to his conscience, and what rod choice is of major importance: it means he still has free will. But Dorian Grays vanity leads his life: he prefers his appearance to his moral principle. Does he sell his soul and if so when? In chapter II Dorian Gray unconsciously sells his soul when he pronounces the wish to stay young forever while the portrait would grow old instead: If it were I who was to be always young and the picture that was to grow old! ( ) I would give my soul for that. Although Dorian Gray never signs contract with the devil, his sacrifice is similar: e trades his soul for the luxury of eternal youth. Nevertheless Dorian Gray makes this wish without knowing that it will became true. So he is rather innocent in chapter two. There isnt a clear moment in the novel where Dorian willingly signs his soul to a demon, there isnt any indication that anything paranormal happened until a month later when the painting suddenly changes after a cruel action. But Dorian Gray clearly believes that the portrait changes are due to the prayer he made when he first saw the portrait: Suddenly there flashed across his mind what he said in Basil Halyards studio the picture had been finished ( ) He had uttered a mad wish that he himself might remain young, and the portrait grow old ( ) Surely his wish had not been fulfilled? (.. ) And, yet, there was the picture before him, with the touch of cruelty in the mouth. This is when Dorian understands that his wish came true, so he is aware of his corruption and in chapter 8 he deliberately choose to become evil. He fell that the time had really come for making his choice. ( ) The portrait was to bear the burden of his shame: that was all.

Explore the potential problems and issues that an organization would Essay

Explore the potential problems and issues that an organization would need to consider when re-sourcing requirements back to thei - Essay Example In recent years however, the benefits of outsourcing have decreased due to increasing costs of production in Asia, long-lead times, poor communication with Asian countries, large quantities for minimum orders, as well as poor quality of products (Green, 2013). Due to these issues, outsourcing countries have made attempts to re-source their production back to their home countries. Undoubtedly, major challenges are foreseen in on-shoring or re-sourcing, not the least of which involves loss of profits, which to any business is always problematic (Green, 2013). Still, businesses have gradually initiated efforts to re-source their production to their home countries mostly because they believe it would be the better option for them in the long run. This paper shall now explore the potential problems and issues than an organization would need to consider when re-sourcing requirements back to their home country and how these potential problems might be addressed or mitigated by the procureme nt function. Body There are different problems which have and will likely emerge for businesses seeking to re-source or in-source their production processes. ... This would imply the importance of some elements of IT skill in the related area, alongside an effective population having the right attitude to flourish in careers related to IT (Williams, 2012). The location need not be in the cities or metropolitan areas, but an area which is still big enough to support the logistics of its production processes. The chosen area must also be low-cost (Qu, et.al., 2010). In general, areas which are the most efficient sources of modern technology have become very expensive areas to reside in; as such, wages for these areas are also expectantly higher than other areas. Under these conditions, it would be difficult for the businesses seeking to establish new re-sourcing areas to achieve profitability without having to sacrifice either the availability of the best technology or the lower wages of the employees (Hirscheim, 2000). The importance of securing an educational system which is responsive to the needs of the industry is also a challenge for thes e businesses. A significant decrease in IT graduates has been observed in the past decade and some areas have even eliminated IT education from their curriculum. The challenge for these corporations would be to revive the enthusiasm of the young population in order to be more responsive to the needs of these businesses and to work out technology issues (Williams, 2012). General Motors has recently considered relevant moves in order to secure insourcing of elements of its production process, mostly bringing back work to Austin, Texas (Thibodeau, 2012). Its insourcing move was however very much challenged with the limited relevant skills needed from its new employees

Environmental Issues (Article Critque) Article Example | Topics and Well Written Essays - 1250 words

Environmental Issues ( Critque) - Article Example One set of risks are specific to the hydraulic fracture process used for shale gas production while the other set of risks apply to all oil and gas production activities where there is much greater operating experience. The last part of the paper shows that the environmental regulations for shale gas drilling vary from state to state and that there are areas of overlap between some of the state regulations and some federal laws. The paper suggests the need for a common set of regulations so that the best practices developed at one drill site can be applied across all projects. 2. Environmental risks specific to shale gas production 2.1 Seismic shocks The major concerns about shale gas production have been around the hydraulic fracture process where the shale rock is caused to fracture by hydraulic pressure. The cracks in the rock propagate 500 to 800 feet in all directions from the casing pipe and the effect is similar to an underground seismic shock. The fracture pressure needs to b e monitored and controlled to prevent the cracks from spreading beyond the shale gas layer (page 4). The general concern with setting off such underground fractures is that the fissures may permit contamination of underground water aquifers that are used for drinking water (page 7). Most shale gas formations are found 4,000 to 8,500 feet below the surface whereas drinking water sources are rarely more than 850 feet deep (page 8). Seismic monitoring is an essential tool to ensure that the underground cracks do not spread beyond the shale gas formation. However, only 3% of around 75,000 hydraulic fractures carried out in 2009 in the US were seismically monitored (page 8). An additional concern is with such underground fracture may lead to earthquakes. The town of Cleburne, Texas has experienced several low intensity earthquakes under 3.3.on the Richter scale in 2008 and 2009 after the start of shale gas exploration in the area when the region has no recorded earthquakes in the previou s 142 years (page 9). Preliminary studies do not find a definite link between shale gas exploration and these earthquakes but the concern remains. The paper does not say whether the hydraulic fractures in the Cleburne area were seismically monitored. 2.2 Fresh water usage and waste water disposal Hydraulic fracturing requires 2 to 8 million gallons of water per well fractured. Though water once used for fracturing can be reused by diluting with fresh water, the Barnett Shale project has used an average of 3 million gallons of fresh water per well and has drilled tens of thousands of such wells (page 12). Apart from the problem of using so much water in competition with other uses, there is the problem of treatment and disposal of contaminated water. The water pumped into the well has chemical additives. When it flows back to the surface it includes any sub-surface water that may have dissolved contaminants such as arsenic, benzene and mercury (page 10). The ‘flow back’ water will happen not just during the hydraulic fracture process but also during the gas production phase of the well. The water is presently being injected into underground saline aquifers but the number of such wells available is too small to handle the volumes of waste water (page 10). Municipal waste water treatment facilities in the area of the shale gas fields cannot handle this volume of water and are not designed for these contaminants. Treated municipal water is also

What are the advantages and potential risks of PR based on Corporate Essay

What are the advantages and potential risks of PR based on Corporate Social Responsibility - Essay Example There comes the term Public Relations, which is highly connected and linked with wide organizational structural framework in modern times. Whatsoever, an organization is practicing in any of the industry of the world, e.g. textile, cement, FMCG, chemical manufacturing, Information Technology, Construction and etc, it do need to maintain its strong reputation and standing among the various media personal, society at large, government bodies and other components of public relations. Because the maintenance of such smooth and swift relationships with the public at large, benefits the organization and its management in the long run and in carrying out its operational and functional procedures in a dynamic, effective and efficient manner. Public relations is a deliberate, planned and sustained endeavors on part of the organization to establish and maintain the aspects of mutual relationship and understanding between the Company (or individual) and the public and thus, this act of Company is considered as the dynamic key to its effective communication in all the major sectors of business, market, government, academic, CSR and not-for-profit (Pria.com.au). Public relations  can be defined as the practice of monitoring and managing the flow of  information  or data between individuals of Company or an  organization  itself and the  public and its various authorities. Broadly speaking, Public relations can include an organization or  any individual  attaining exposures and making interactions  to their audiences of different classes, using specifically the subjects of public interest and certain news information which do not demand any direct consideration or payment. Thus, the one of the major objectives which the Company aims to meet as a result of its association with public and maintaining its good relationships and connections with it, is

What Makes People Commit Benefit Fraud?

What Makes People Commit Benefit Fraud? Introduction Benefit fraud is, according to some members of the government and some media sources, committed by dishonest people and is a blight on our nation which sucks up huge amount of money that could otherwise be used for the improvement of public services. Another perspective might argue that benefit fraud is a symptom and reflection of our unequal society. The first view tends to place the blame on the individual while the latter tends to place the blame on society. The attitude that a textual source adopts towards this questions can provide some insight into the way in which they construct the issue. Social psychology has analysed the way in which we make decisions about why something happens in terms of attributions. Hogg Vaughan (2002) explain that attributions in social psychology describe how people make decisions about the actions of other people specifically what is it that motivates their actions? One of the most well-known of these models of attributions was put forward by Kelley (1967, 1973). Within this model, peoples behaviour is either attributed to external causes or to internal causes on the basis of how their behaviour varies with the following factors: its distinctiveness, its consistency and the consensus. Attribution theory has been further extended by the work of Weiner (1986) which breaks down how attributions are made into three categories. The first is the locus of control this refers to the boundary between internal and external causes. The second is stability this refers to the extent to which the cause is capable of change. The third is the controllability this refers to how much control a person is perceived to have over their future performance. The way in which the examined texts make attributions about peoples behaviour, in this case benefit fraud, should show their attitudes towards those types of people. For this study, four extracts from The Guardian newspaper were used. The Guardian is traditionally a politically left-leaning publication. The hypothesis for this study was that The Guardian newspaper, in its implicit explanations of the reasons people commit benefit fraud, would tend to emphasise those reasons that focussed on the effects that society has on individuals rather than on individual factors such as personal deviance. In terms of attribution theory, then, the attributions made for benefit fraud would tend to be external to people, would tend to be permanent and beyond peoples control. Method Content analysis is a type of qualitative research method that involves counting the instances of words and then making inferences from these figures. Thematic analysis, however, is a related procedure that involves looking at a text in order to discover the themes that emerge from it, but it does not have the same emphasis on word frequencies. From this difference it can be seen that a thematic analysis aims to understand the data rather than know it. The procedure used for this thematic analysis was to read the extracts relating to benefit fraud and to make notes in the margin as themes arose in the coding. The themes that arose from all the extracts were then examined in total and any potential connections between the themes were analysed in terms of social psychological theories. In carrying out this analysis, one of the most important factors was maintaining a state of reflexivity. Marks Yardley (2004) point to two important components of reflexivity in this type of study. The first is a social critique this means examining how the themes relate to power structures in society. The second is the researcher considering their own attitudes towards the subject being investigated. Results From the analyses of four excerpts from The Guardian, the following three themes emerged. Theme 1: The Catch 22 Administrative Complexity The first theme emphasises the idea that there are often high levels of administrative load involved in applying for benefits. Davies (2005) for example emphasised the amount of form-filling involved for people and how complicated the process is: Many (†¦) fear endless form-filling while moving off benefits, into tax credits and then, heaven forbid, reapplying for benefits if work falls through hoping that between the Inland Revenue, job centre and the housing office, no one misplaces their form. (Davies, 2005) This focus on the complications of the process can also be seen in Tickles (2006) article which focuses on the difficulties of the system. In particular for one 19-year old trying to put himself through the education system in order to gain A-levels so that he can get a degree, the benefits system seems to be working against him. Not only that but the administrative system has him caught in a Catch 22: According to the benefit rules, if you turn 19 and are homeless, the education game changes. You are no longer eligible for income support, which in turn entitles you to housing benefit. This benefit requires claimants to have an income. Instead, you must claim jobseekers allowance (JSA), which means declaring yourself available for work, and eventually attending government-approved New Deal training. This will very likely have nothing to do with your studies, or those you might like to begin. (Tickle, 2006) According to this account, the man in this article has clearly been caught in the administrative complexities of the situation, something for which he cannot be personally blamed. Theme 2: Social Hardship A strong theme throughout these articles emphasises the difficulty of the circumstances of many of the people that may be involved in benefit fraud. The young man described by Tickle (2006) had been forced to move out from the family home because of problems there and had moved into homeless accommodation. These points are further highlighted in the letters page of The Guardian which points to some of the social circumstances of those who might be claiming benefits fraudulently. Serwotka (2005) points out that: We also see from estimates reported to the public accounts committee that while benefit fraud is declining, errors in payments are on the increase. As the union representing the workers who have to implement these tough conditions, PCS does not believe that getting tough is the best way of helping some of the most vulnerable in society to obtain and keep jobs. (Serwotka, 2005) This places benefit questions within a wider context of lowering rates of fraudulent behaviour and the implicit persecution of those who are the most vulnerable. Theme 3: Fraud Despite Labelling A consistent way in which the writers in The Guardian talked about benefit fraud was in reference to the negative effects of labelling. The implication of this was that while reasons for benefit fraud might include social circumstances and administrative complexity, as discussed above, fraud was carried out despite the strong negative connotations attached to it by the government and others. Davies (2005), for example, points out that many people: †¦feel targeted and blamed for anti-social behaviour, benefit fraud, scrounging on incapacity benefit. They fear being punished for their childrens school attendance, accused of bad parenting and having their children put into care. (Davies, 2005). A culture of fear is emphasised by Beresford (2005) in that vulnerable people are consistently bombarded by messages that fraud should be avoided. Reporting on a Department of Health study it was found that: One of the strongest messages from the study is the real commitment of many people who have been written off as dependent to make a contribution to their community. But this is hindered by official talk of benefit cheats; of getting a million people off incapacity benefit; a preoccupation with paid employment; and an often inflexible and unsupportive labour market. (Beresford, 2005) Implicit within this analysis is the idea that people who do commit benefit fraud must have a good reason for doing so because the social pressure created by the government not to carry out fraud is so great. Discussion The themes found in this textual analysis of why people commit benefit fraud points to the involvement of a number of established social psychological theories. Each of the themes examined clearly shows how social and systemic reasons were seen, by these articles in The Guardian, to be at the root of why people commit benefit fraud. The first theme of administrative complexity tended to attribute the causes for fraudulent benefit claims to administrative dilemmas and catch-22 problems. This clearly places the reasons for behaviour outside a persons locus of control and implicitly places the cause for the behaviour onto the system. As the system is being blamed this will tend to be a relatively stable factor that will continue into the future. Finally, administrative factors are largely beyond the control of the individual as they are decisions made by the state. The second theme of social hardship is not quite as clear-cut as the first but there are similar tendencies in the analysed attributions. Here social hardship is seen to act as an external force but the decision of the man discussed in this case to commit benefit fraud is seen, to some extent, to be internal. The reasons given for this, however, are external in that it is the system, again, and its complexities and apparent loopholes, that has forced him to take this decision. The final theme did not fit easily into the ideas provided by attribution theory, but, is better suited to those of conformity. Asch (1952) posited that people tend to form the norms for their own behaviour by looking at those around them and come to a conclusion about how they should act based on this. What was clear from Aschs (1952) experiments is that people are highly affected by other peoples behaviour. The third theme, therefore, tends to emphasise the stigma attached to benefit fraud. It follows that people who do commit benefit fraud must have very good reasons for doing so as they are fighting against the normalising pressure of what is generally considered right. Taking a step up in level of analysis, the way that The Guardian makes attributions about people committing benefit fraud can be examined in terms of in-group and out-group attributions. Researchers have found that when making in-group attributions, people tend to display a self-serving bias (Hewstone, 1989). It is assumed that The Guardian newspaper, as it has been traditionally considered a politically left-wing newspaper, is likely to view itself as at least sympathetic to those committing benefit fraud. This would be explained in the ideas of intergroup attribution theory as a self-serving in-group bias. In general then, the hypothesis that textual extracts from The Guardian would tend to defend those committing benefit fraud was supported. This was analysed in terms of attributions with the results showing that they tended to be outside a persons locus of control, tended to be ongoing and permanent. Through these attributions the causes, or even blame, for peoples actions tended to be situated externally. From the perspective of power structures, the idea that The Guardian should defend those who are most vulnerable in society was also consistently supported. References Asch, S.

The Writings of J.D. Salinger Essay example -- J.D. Salinger Essays

The Writings of J.D. Salinger Jerome David Salinger, known as J.D., is an American short story writer and novelist. He was born on January 1, 1919 and is still alive at the age of 81. J.D. Salinger was born and raised in Manhattan. He went to prep school at Valley Forge Military Academy from 1934-1936. He spent 5 months in Europe when he was 18 or 19 years old. Then, in 1937 and 1938 he studied at Ursinus College and New York University. From 1939 to 1942, he went to Columbia University where he decided to become a writer. Salinger published short story collections and one novel. His best known work, The Catcher in the Rye, was published in 1951. The short stories he wrote were "Nine Stories" in 1953, "Franny and Zooey" in 1961, "Raise High the Roofbeams, Carpenters and Seymour: An Introduction" in 1963, "Young Folk" in 1940 and "A Perfect Day for Bananafish" in 1948. Many critics have considered J.D. Salinger a very controversial writer because of the subject matters he wrote about. For example Salinger wrote ab out religion, intellectuals, emotional struggles of adolescents, loneliness and symbolism (Jones). Some critics feel his writing was inappropriate because of the topics he wrote about. The main characters were considered misfits of society. The characters generally did not fit in with traditional American culture. They could not adjust to the real world. However, Salinger's most successful stories are the ones about people who could not adjust. The super-intelligent humans who had to choose between the American culture at that time and the moral world, or choose between the "phony" real world and the morally "pure" world. Salinger creates these misfits, as heroes who do not fit into society. They struggle between t... ...up. He went against society to show how wrong he thought it was. He has made the reader see what was wrong during this time period in a very different and controversial way (Hamilton 32).

Development of Gothic Architecture in Relationship to Medieval Society

The Middle Ages covered a thousand year span. The period began after the schism of the fifth century in which the Roman empire was split into east and west. It continued until the start of the Protestant Reformation in the sixteenth century. The medieval period was notable for the origins and development of Gothic architecture. Because there was so much upheaval during the Middle Ages, the one constant was the Church. At that time the only denomination was Catholic.The Church was usually the largest structure in the medieval environment and was a main gathering place in which a variety of functions (which today would be provided by civic  buildings), occurred. (The Middle Ages, 1). Since the holy Catholic Church had already been a powerful institution at the conclusion of the Roman Empire, it continued to be the unifying force among the many small kingdoms that would develop into Europe. Replete with its own laws and large coffers, it wielded much influence during this time ( Enter the Middle Ages, 1).In addition, it had kept much from the ruins of the ancient world and became one of the centers of learning during during the Middle Ages. Not only did the Church preserve much of classical Latin knowledge, but it also maintained the art of writing.The cathedrals developed learning specialties such as rhetoric or logic in schools named cathedral schools. (Middle Ages, Learners. Org, 1). Whether one’s station was that of lowly peasant or of noble lord, the Church touched everyone’s life. Rank or class did not matter. Within towns , with the exception of a small amount of Jews, everyone in Europe was Christian. However, beyond the core areas of western Europe, there remained many people with little or no contact with either Christianity or classical culture.Outside the deurbanized remnants of cities the power of the central government was greatly  lessened and governmental authority was delegated to local lords who supported themselves directly fro m the territories over which they held power. This was the beginning of the feudal system ( Enter the Middle Ages, 1). For safety and defense people in the Middle Ages formed small communities around a central lord or master, living on a manor , which consisted of the castle, the church, the village, and outlying farmland. In exchange for living on his land, the lord gave protection to his serfs. Manors were isolated with occasional visits from peddlers, pilgrims on their way to the Crusades, or soldiers from other fiefdoms.  (Sobol, 22).Bishops, who were frequently wealthy, and came from noble families, ruled over a group of parishes called a diocese. Parish priests, however, came from humbler backgrounds and often had little education. The village priest tended the poor and sick, and if he was capable, taught Latin and the Bible to the youth of the village. (Enter the Middle Ages, 2). Medieval cathedrals sometimes functioned as marketplaces with the different portals of the mark etplaces containing sellers with their produce: items such as textiles might be at one end, while fuel, vegetables, and meat at another. Sometimes the clergy tried to put a  stop to the marketers. They tried to block access to the cathedral. But it was in vain.The sellers were not taxed on the items they sold inside the church; while the items they sold outside were. (Chartres, 1). The Church was all in all during medieval times. From the moment of its baptism a few days after birth, a child began its life of service to the Lord and to His Church. As the child developed , it would be taught basic prayers- and unless ill- would go to church every week. Every person was required to pay heavy taxes to support the Church.The reward for this was being shown the way to everlasting life and  happiness- a great trade off for lives that were often short and difficult. In addition to collecting taxes, the Church also granted special favors for people who wanted assurance of a place in hea ven. Gifts in the form of land, crops, flocks, and even serfs scrambled into the coffers. All this largess allowed the Church to become very powerful. As a result, it often employed this power to influence kinds and do as they wanted. (Enter the Middle Ages, 2). The power continued with the Pope who was considered to be God’s representative on earth. If someone went against the Church, the Pope could excommunicate them.This meant that the person could not attend any more church services or receive the sacrament, thus ensuring that they would go straight to hell when they died. At a time when everyone believed in heaven and hell, and all belonged to the Church, this excommunication was an unbearable horror. (Ibid, 2). The population increased throughout the Middle Ages. As it expanded in the 12th century, the type of church that had previously been used for worship; the ones built in the Roman or Romanesque style, with round arched roofs, became too small. Some of the grand ca thedrals became maxed to their structural limits.Although they built more mightily, going ever higher and larger, it appeared to be too much and these grander edifices collapsed within a century or less of their construction ( Enter the Middle Ages, 3). Enter a man who was about to change the style of these Middle Age churches and with it, bring forth a whole new field of architecture- gothic. Abbe Suger had been affiliated with the Church of Saint Denis in Paris for a good part of his life. The building needed repairs, so he took on the reconstruction, bringing in the finest of workers from the Low countries and from Italy.For his inspiration, Abbe Suger  looked to Canterbury Cathedral. Pilgrimages had been an important part of religious life in the Middle Ages as people journeyed to visit religious shrines. Suger particularly admired Canterbury Cathedral for its stained glass windows. Desirous of creating a physical representation of the the Heavenly Jerusalem, Suger aimed for a place of light that would speak of the positive aspects of the religious life: Redemption as opposed to the hellfire and damnation that was constantly being sermonized in the dark and dank Romanesque churches.Suger conceived of the idea â€Å"lux continua† – this theory would transform his church into one of  radiance and splendor, magnifying the spirit. He and his team gave themselves to the reconstruction of the church. After a four year renovation, the choir was completed in 1144. In a magnificent ceremony, complete with King Louis VI and Eleanor, and other notables, the church was dedicated to the Lord. With its thin columns, stained glass windows, and a sense of verticality, the choir of Saint Denis originated the elements that would be developed further during the Gothic period. Now architects were able to expand Saint Denis upward to more than twice the height of the earlier cathedral and free the walls to be filled with stained  glass.The great expanse of glass helped Abbe Suger with his goal of â€Å"lux continua†. These brightly colored stained glass windows were decorated with parables and stories of the Bible that would help inform the illiterate in their faith. Trade guilds funded other windows and the decorations contained within demonstrated what life was like during this medieval time. Saint Denis was designed along the lines of sacred geometry: the use of number angles, shapes that mirror the principle of the faithful believer, and flying buttresses that would support those higher ceilings and slender columns; the verticality suggesting aspirations to heaven  Additionally, Saint Denis contained a golden cross and a golden altar where kings and nobles donated their precious jewels (Gothic Art and Abbe Suger, 1)The influence this church had over French architecture was profound because it was also a political symbol. Suger virtually ran the kingdom while Louis VI was away on the Crusade. Yet for Suger, the Church was neither political symbol nor an architectural one, but solely a religious symbol. His main goal in its design was to honor God and Saint Denis. Suger had become fascinated by the religious implications of the light. He had inscribed on the main doors, which  are representative of the passion and resurrection of Christ: The noble work is bright, but being nobly bright; That work should brighten the minds, allowingThem to travel through the light. To the truth where Christianity is the true door (Simson,111). The Gothic style had emerged. It would give rise to the development of many other buildings and cathedrals who copied its characteristics, the most visible of which was its verticality. A skeletal stone structure, pointed arches using the ovoid shape, ribbed vaults, clustered columns, sharply pointed spires, flying  buttresses and sculptural gargoyles became part of the Gothic look. (The History of Art, 255).One of the most superlative examples of Gothic architecture can be f ound in Chartres Cathedral. Chartres, fifty miles from Paris, is considered to be extremely outstanding in its use of the Gothic elements. It was rebuilt in the Gothic style after a fire had decimated the building. Called a miracle of stained glass and stone, it was created in the form of a cruciform and dedicated in 1260. Chartres contains one of the most complete collections of medieval stained glass in the world. The Rose Window contains a sun and a rose.Jesus Christ, the Son, represents the sun, while Mary is the rose without thorns. Also there are depictions of kings and lords in additional stained glass, but their lower elevation connotes submission to the Lord. Along with many stained glass windows containing biblical stories which are typological allegories between the Old Testament prophecies and the New Testament, there is much statuary. Rows of arches and niches within the arches contain the statues. (Chartres,Online 1). Within the confines of the Cathedral is a sacred re lic that was given by King Charlemagne. It is called the â€Å"Sancta Camisia,† and is said  to be clothing worn by Mary.Charlemagne received it on a pilgrimage to Jerusalem. This clothing, also called the cloak of the Virgin, was the source of much pilgrimage during the medieval times. The Cathedral was the life of the town and these pilgrimages brought in much revenue that the town depended upon. These pilgrimages occurred four times a year. Chartres, Wikipedia, 1). Although Raphael despised the Gothic style and named it derisively after the savage Goths who had ransacked Rome, the style survived and is an everlasting style of beauty and majesty. It is a wonderful contribution from the Middle Ages.

Definition of Stump Speech

Definition of Stump Speech Stump speech is a term used today to describe a candidates standard speech, delivered day after day during a typical political campaign. But in the 19th century, the phrase held a much more colorful meaning. The  phrase became firmly established in the early decades of the 1800s, and stump speeches got their name for a good reason: they would often be delivered by candidates who literally stood atop a tree stump. Stump speeches caught on along the American frontier, and there are numerous examples where politicians were said to be stumping for themselves or for other candidates. A reference book in the 1840s defined the terms to stump and stump speech. And by the 1850s newspaper articles from around the United States often referred to a candidate taking to the stump. The ability to give an effective stump speech was considered an essential political skill. And notable 19th-century politicians, including Henry Clay, Abraham Lincoln, and Stephen Douglas, were respected for their skills as stump speakers. Vintage Definition of Stump Speech The tradition of stump speeches became so well-established that A Dictionary of Americanisms, a reference book published in 1848, defined the term To stump: To Stump. To stump it or take the stump. A phrase signifying to make electioneering speeches. The 1848 dictionary also mentioned to stump it was a phrase borrowed from the backwoods, as it referred to speaking from atop a tree stump. The idea of linking stump speeches to the backwoods seems obvious, as the use of a tree stump as an improvised stage would naturally refer to a location where land was still being cleared. And the idea that stump speeches were essentially a rural event led to candidates in cities sometimes using the term in a mocking manner. The Style of 19th Century Stump Speeches Refined politicians in the cities may have looked down on stump speeches. But out in the countryside, and especially along the frontier, stump speeches appreciated for their rough and rustic character. They were free-wheeling performances that were different in content and tone from the more polite and sophisticated political discourse heard in the cities. At times the speech-making would be an all-day affair, complete with food and barrels of beer. The rollicking stump speeches of the early 1800s would typically contain boasts, jokes, or insults directed at opponents. A Dictionary of Americanisms quoted a memoir of the frontier published in 1843: Some very good stump speeches are delivered from a table, a chair, a whiskey barrel, and the like. Sometimes we make the best stump speeches on horseback. John Reynolds, who served as governor of Illinois in the 1830s, wrote a memoir in which he fondly recalled giving stump speeches in the late 1820s. Reynolds described the political ritual: Addresses known as stump-speeches received their name, and much of their celebrity, in Kentucky, where that mode of electioneering was carried to great perfection by the great orators of that state. A large tree is cut down in the forest, so that the shade may be enjoyed, and the stump is cut smooth on the top for the speaker to stand on. Sometimes, I have seen steps cut in them for the convenience of mounting them. Sometimes seats are prepared, but more frequently the audience enjoys the luxury of the green grass to sit and lie on. A book on the Lincoln-Douglas Debates published nearly a century ago recalled the heyday of stump speaking on the frontier, and how it was viewed as something of a sport, with opposing speakers engaging in spirited competition: A good stump speaker could always attract a crowd, and a wit combat between two speakers representing opposite parties was a real holiday of sport. It is true that the jokes and counterstrokes were often feeble attempts, and not very far removed from vulgarity; but the stronger the blows the better they were liked, and the more personal, the more enjoyable they were. Abraham Lincoln Possessed Skills as a Stump Speaker Before he faced Abraham Lincoln in the legendary 1858 contest for a U.S. Senate seat, Stephen Douglas expressed concern about Lincolns reputation. As Douglas put it: I shall have my hands full. He is the strong man of the party - full of wit, facts, dates - and the best stump speaker, with his droll ways and dry jokes, in the West. Lincolns reputation had been earned early. A classic story about Lincoln described an incident the occurred on the stump when he was 27 years old and still living in New Salem, Illinois. Riding into Springfield, Illinois, to give a stump speech on behalf of the Whig Party in the 1836 elections, Lincoln heard about a local politician, George Forquer, who had switched from Whig to Democrat. Forquer had been generously rewarded, as part of the Spoils System of the Jackson administration, with a lucrative government job. Forquer had built an impressive new house, the first house in Springfield to have a lightning rod. That afternoon Lincoln delivered his speech for the Whigs, and then Forquer stood to speak for the Democrats. He attacked Lincoln, making sarcastic remarks about Lincolns youth. Given the chance to respond, Lincoln said: I am not so young in years as I am in the tricks and trades of a politician. But, live long or die young, I would rather die now, than, like the gentleman, - at this point Lincoln pointed at Forquer - change my politics, and with the change receive an office worth three thousand dollars a year. And then feel obliged to erect a lightning rod over my house to protect a guilty conscience from an offended God. From that day forward Lincoln was respected as a devastating stump speaker.

What Freezing Point Depression Is and How It Works

What Freezing Point Depression Is and How It Works Freezing point depression occurs when the freezing point of a liquid is lowered or depressed by adding another compound to it. The solution has a lower freezing point than that of the pure solvent. Freezing Point Depression Examples For example, the freezing point of seawater is lower than that of pure water. The freezing point of water to which antifreeze has been added is lower than that of pure water. The freezing point of vodka is lower than that of pure water. Vodka and other high-proof alcoholic beverages typically dont freeze in a home freezer. Yet, the freezing point is higher than that of pure ethanol (-173.5Â °F or -114.1Â °C). Vodka may be considered a solution of ethanol (solute) in water (solvent). When considering freezing point depression, look at the freezing point of the solvent. Colligative Properties of Matter Freezing point depression is a colligative property of matter. Colligative properties depend on the number of particles present, not on the type of particles or their mass. So, for example, if both calcium chloride (CaCl2) and sodium chloride (NaCl) completely dissolve in water, the calcium chloride would lower the freezing point more than the sodium chloride because it would produce three particles (one calcium ion and two chloride ions), while the sodium chloride would only produce two particles (one sodium and one chloride ion). Freezing Point Depression Formula Freezing point depression can be calculated using the Clausius-Clapeyron equation and Raoults law. In a dilute ideal solution, the freezing point is: Freezing Pointtotal Freezing Pointsolvent - ΔTf where ΔTf molality * Kf * i Kf cryoscopic constant (1.86Â °C kg/mol for the freezing point of water) i Vant Hoff factor Freezing Point Depression in Everyday Life Freezing point depression has interesting and useful applications. When salt is put on an icy road, the salt mixes with a small amount of liquid water to prevent melting ice from re-freezing. If you mix salt and ice in a bowl or bag, the same process makes the ice colder, which means it can be used for making ice cream. Freezing point depression also explains why vodka doesnt freeze in a freezer.

The Political Objectives of International Trade Research Paper - 1

The Political Objectives of International Trade - Research Paper Example Pushing aside the philosophical exception to buying regionally, it is very difficult to decipher what products are manufactured partially, mostly, or entirely from any one specific region. In most cases, raw materials are gathered here, assembled there, and shipped via a third entity to an entirely new location for packaging. The item is sold and the funds deposited in a completely different location which invests the money in an endless array of regions providing myriad avenues of revenue for untold amounts of regions. Buy from, for example, A bumper sticker that suggests â€Å"Be American. Buy American.†, might be manufactured in the USA with imported glue from Chile, ink from Jamaica, and paper from China. If, after the purchase, one is dissatisfied with the product, a toll-free Hotline for consumers is routed to India, Russia, or Hong Kong. The difficulty of deciding what has been completely and entirely manufactured, represented, transported, and supported is like finding a needle in a haystack. After reading the Chapter, my viewpoint hasn’t changed much from price and quality. I found the polling interesting â€Å"2/3 supported trade restrictions† (pg. 135). ... g paid to US and European farmers allowing them to sell crops on the world market at reduced prices driving down prices of commodities in developing nations (pg. 142). The impression I have is US farmers are paid to ‘not grow’ crops for availability on the world market since the number of crops produced if all US farmers did grow crops, would dramatically overwhelm the markets and drive developing nations out of business for good. The most effective use of government subsidies is not from the US, but from China who pays subsidies for their companies on imported oil driving the price of gasoline to record numbers. The problem, it appears, is dissecting information from neutral informants. The book includes a secondary â€Å"Supporting† position about a ‘Conservative’ misstep; â€Å"George W. Bush†. Each side seems to have an agenda and wishes to persuade, albeit subtlety, towards their particular point of view. All three sides-Left, Right, Centr al-seem to persuade instead of informing. It is difficult to see the unvarnished truth about International Trade from any writer. Each writer seems to have a polar objective. The political objectives of International Trade are the reason Trade is mired in the grey area for understanding. Political considerations outweigh most logical directives towards â€Å"common sense† free trade and/or their restrictions. The book even muddies the Trade waters even further by proclaiming â€Å"List† an economic icon with regard to Trade. The list is referenced as suggesting a Country that cannot produce ‘X’ amount for export should get out of the business of that particular export ‘X’. At the same time, the book vilifies Europe and the USA-as examples-of dominating and controlling the market with respect to crops and commodities.
