Reflection Paper on Passing by Nella Larsen Term
Reflection on Passing by Nella Larsen - Term Paper Example Irene was a woman who hated racism. Irene learns that Clare has been hiding her African inheritance throughout her wedding. Heatedly, Irene returns home and decides to keep away from Clare, but finds herself yielding to Clare's attraction once again. Clare wants to retort the black community and induces Irene to invite her to a social circle. During the dance, Irene resentfully comprehends that Clare seems to get along with everyone and grows disappointed with her. When Irene repeatedly watches Clare's luck augment concerning her hazardous risks, she feels endangered and in the end, kills Clare by pushing her out of the window. Not only does Clare pass in skin shade, but she also passes in societal rank, which intimidates Irene's outlook of the idyllic middle-class African American. Because Clare passes for white, marries a rich man and hides her African race. Although Irene resented the way Clare hid her African race but still she supported her because of the racial ties she shares with her. As Clare was afraid of what will happen if she will show that she is African. She thought that her social class will fall and she will lose all friends but Irene didnââ¬â¢t believe it to be true but still she doesnââ¬â¢t go against her as this would be against her rules as well.

Choosing first topic - Essay Example 295). Forest lands, adjacent to small scale farming fields, fall victim to deforestation, during the course of expansion of agriculture. As such, deforestation has principally been the outcome of small scale agricultural activity that had been undertaken along the edges of the forest. Moreover, infrastructure development, such as the construction of roads, has resulted in the widespread felling of trees, in the areas abutting forest land . At present, a few of the smaller countries of Southeast Asia, like Malaysia, have been left with negligible forest area. This dismal state of affairs is on account of the unabated deforestation conducted in these countries (Carr, 2004, p. 296). In addition to the expansion of small scale agriculture, infrastructure development, like the construction of roads and other activities, leads to deforestation. The 1990s were witness to the unprecedented clearing of forests in Asia. This was occasioned by enhanced demand for timber and the continual migrat ion of rice farmers, into what had previously been remote regions. These regions became accessible, due to the increased felling of trees .Latin America, with its abundance of closed tropical forests, has been host to most of the research that has been conducted on tropical deforestation. ... Furthermore, deforestation is also the outcome of economic considerations, like low domestic costs, increase in the price of products and the influence on ecology by industrial and urban centers in remote locations. The latter has been seen to be the cause behind deforestation, in a third of the cases (Geist & Lambin, 2002, p. 146). Hence, Market forces have a tangible effect on furthering deforestation. Moreover, deforestation is the outcome of a necessity to generate foreign exchange earnings at the national level, and this has been seen to be prevalent in 25% of the cases. On the whole, there is scant variation in the elements that pertain to economic development in a burgeoning cash economy. As a consequence, these features promote deforestation, in a very powerful manner (Geist & Lambin, 2002, p. 146). As such, economic reasons also contribute to deforestation in tropical regions. Consequently, expansion of agriculture has been deemed to be the most important cause of deforestat ion, and this has been estimated at 96% of the instances. Some of the facets of such expansion are the conversion of forests, on a permanent basis, to land on which cattle graze, shifting cultivation is practiced and agriculture is colonized. In addition, the tropical rainforests of Asia are subjected to considerable commercial wood extraction (Geist & Lambin, 2002, p. 145). In Asia, commercial wood extraction has also been identified as a major element, in bringing about deforestation. The World Bankââ¬â¢s 1989 World Development Report disclosed that deforestation was rampant in fourteen developing countries of South America, Africa, and South-East Asia. This report also revealed that more than 250,000 hectares of tropical forests were being destroyed annually, in these

Purposes of police patrol - Research Paper Example Purposes of police patrol Knowledge about the neighbourhood is the essence of every police patrolling function. ââ¬Å" Knowledge about the physical structure of the neighbourhood, Boundaries and adjoining areas, Alleys, Businesses, Layout of streets, dead end streets, geographical directionsâ⬠etc would enhance the patrolling functions very much. ââ¬Å"Foot Patrol, Motorcycle Patrol, Motorized Patrol, Bike Patrol, Horse Patrol, Aircraft Patrol, Watercraft Patrol, Routine Patrol, Directed Patrol, D-Runs, Saturation Patrol, Split Force, Suspect-Oriented Patrolâ⬠etc are some of the most common patrolling programs undertaken by police force. Increased probability of accidents is the major issue in high speed pursuits. ââ¬Å"Research from the 1980s indicates that nationwide property damage occurs in about one of every five pursuits, personal injury in one out of seven, and death in approximately one out of every thirty-five pursuitsâ⬠. Moreover increased rate of law suits against the patrolling officers is another issue associated with high speed pursuits. It should be noted that in high speed pursuits, the possibility of causing damages to the innocent people is more. Casualties in the form of death and injury can occur to the innocent people while the police officers chase criminals at a high speed using different types of vehicles. ââ¬Å"California police chased more than 7,000 drivers in 2003. The chases resulted in 58 deaths, including 18 innocent individuals who werent involved in the pursuit".

Stereotype Paper Research Example | Topics and Well Written Essays - 750 words
Stereotype - Research Paper Example Our society is plague with stereotypes, and even though we live in a world that is deemed civilized, prejudice will never be extinct. The turn of the nineteen century witnessed a new era for women. No longer were women contented to stay in the background, or fade in the shadows of their husbands. Having been in the air-force I have witnessed and heard how men view women in a mans world. They resent the fact that they will have to take orders from a woman superior. They have biases that have no foundation, other than the fact that they grow up hearing over and over the criteria that make women women. A woman should do what she does bestââ¬â¢nurturing her husband and children. During my service in the air-force, one case in particular has a ineradicable imprint in my mind. My squadron had a woman drill sergeant; and my team-mates resented having to salute a woman or take orders from her. Many times they would pretend to forget and addressed her as ââ¬Å"sir.â⬠She was well aware of their hostility and that made her more militant than most male officer. Their reaction to her was predetermined, she knew it, and was determined to change their minds. Only the best she would accept, she had to prove herself, to show us that she can do a ââ¬Å"mans job. She was dauntless, consequently, my team was first in all training exercise. My colleagues were using a hand-me-down stereotyping. They were perpetuating a myth, a myth that held its ground for many centuries, It was only in 1976, less than fifty years ago, that the first woman was allowed to register in the air-force. The logic that was displayed here is dogmatic. According to the book Introduction to Logic, ââ¬Å"Dogmatism is the position taken by a person who asserts his or her belief as what should be the case: no room for disagreement is possible in this case, and if there is no room for disagreement, the possibility of argument also disappears.

CompInnova System Project Requirements
CompInnova System Project Requirements The CompInnova project is focused upon the development of an innovative inspection methodology, with automated and manual capabilities, for any type of composite and metallic aircraft structures. Within this report, project requirements and specifications related to structural integrity, damage repair and development of a vortex robot, are presented and discussed in the following order: A qualified Phased Array (PA) method related to the structural integrity approach, is an advanced non-destructive testing method used to detect component failures (i.e. cracks), and can be used to assess the component condition. It is presented in chapter 2. An Infrared Thermography (IRT) method, also related the structural integrity approach, is used to determine the presence of flaws by monitoring the flow of heat over a surface, and is presented in chapter 3. A Damage Tolerance (DT) structural integrity assessment technique is used to fracture load for a specified defect size, and predict the required length of time for a sub-critical defect to grow to the size that causes fracture at given load. The DT is presented in chapter 4. Following the structural integrity assessment, a preliminary assessment of the specifications of the repair module of the vortex robot is presented in chapter 5, with the repair module envisaged to perform scarfing or stepped lap repairs on composites as well as bonding repairs on metals. The repair module, as well as the structural integrity assessment systems, is a part of a vortex robot, for which a detailed overview of the existing state of the art in NDT robotic technology is presented in chapter 6. In addition, an overview of the determined project requirements and specifications related to the proposed NDT novel vortex robotic mechanism is presented as well. The project requirements for the CompInnova system has been drafted and agreed by all the participants in this document. Phase Array (PA) technique is an advanced non-destructive testing method used to detect component failures. PA is used for in service inspection and characterization of faults in metallic, as well as composite components. PA uses transducers made up of individual elements that can each be independently driven, by which it is able to decrease the complexity and the handling of an ultrasonic testing system. The PA probes are connected to specially adapted drive units with independent, simultaneous emission and reception along each channel. 2.1 Phased Array Transducer The PAUT transducer should be a linear array transducer with number of elements between 16 and 128 and the central frequency should be ranged between 2 and 5 MHz so that minimum ultrasonic inspection requirements are satisfied for a range of different material structures. The element pitch would be between 0.5 and 0.8 mm (high resolution probe) and it will be defined according to the minimum detectable defect, the properties of the scanned samples and the quality of the acquired ultrasonic images. Furthermore, the array aperture (coverage area rate parameter) and the element length would be finally determined according to the final array specifications. The moving velocity for the array would be approximately 20mm/sec and dependent on the characteristics of the scanned sample for flat or slightly curved surfaces. The transducer would be able to be connected with any PA system via an array interface (i.e. 128 element Hypertronics generic array interface) with cable length that will be defined by the needs of the outdoor inspections required (i.e. required manipulation region of the probe, especially on large structures) and the quality of ultrasonic data acquired. The array should have the capability to directly be integrated in any manipulator for automated operation however it would also be possible to be used in manual inspection procedures with encoded capability along the movement direction with the aid of special encoding configuration that will be continuously attached with the array. By marking the necessary inspection paths on the sample surface and performing several passes with the probe, large areas can be inspected manually. The wedge coupled with the array would have a thickness between 30 and 35 mm and with an angle that is always dependent on the inspection sample thickness (i. e. make sure that reference signals like front and back wall echoes are detectable and visible) and the type of incidence wave required (i.e. longitudinal or shear wave). Precautions will be taken in order to maintain the array at a proper contact arrangement with the testing surface. Water mist, gel or combination of both, are used as a couplant before scanning. The phased array probe would have potential to be interconnected with PA instruments and effectively all the necessary functions for ultrasonic inspection procedure can be performed by the integrated system, which are: automatic recognition of the installed ultrasonic transducer by the PA instrument, ultrasonic array element configuration, system calibration for reliable inspections, gathering of acquired ultrasonic data, A-scan, B-scan and C-scan imaging of data, real time or post processing of acquired data, interconnection with manipulators for acquisition of probe X-Y-Z position, mapping software development for the acquired ultrasonic data, and editing, storing and loading of array configurations. 2.2 Ultrasonic Data Acquisition Mapping Software Ultrasonic data acquisition mapping software would be developed with the aid of installed software environment (i.e. Labview environment) on the PA instrument and therefore processing and visualization of the acquired ultrasonic data can be obtained. All the element firing and probe-wedge configurations can be modified within the software environment. More specifically the user determines the scanning method (linear, half step or FMC) and the number of active elements. This is a procedure that allows the user to adjust all the involved parameters of the ultrasonic hardware by carefully interfacing with the software. Figure 2.1: Representation of an Ultrasonic Data Acquisition Mapping Software The parameters of array and wedge operation can be adjusted. Operating frequency, active aperture elements, beam step, acquire elements and wedge geometry can be set according to the inspection requirements. Array and wedge geometries can be saved or loaded. After the setting of the array-wedge configuration and all the data from PAUT and manipulator are available the scanning can commence. When operating, any type of acquisition display (A scan, B scan or C scan) would be available and so watch the progress of the inspection. Sizing of defects or regions of interest can take place using different image processing techniques or by simply implementing the typical 6db method. 2.3 Conclusion The PA technique will be employed within the advanced defect detection software for detecting very small size flaws in aircraft structures, while achieving a high POD without increasing the scanning time dramatically. This is achievable with the PA technique, since it is able to reduce the amount of sensors as well as the overall complexity of the system applied, while enabling independent and simultaneous emission and reception along each channel.

Free Essays - Development of Theme in Twains Adventures of Huckleberry Finn :: Adventures Huckleberry Huck Finn Essays
Development of Theme in Twain's Adventures of Huckleberry Finn In Mark Twain's novel, The Adventures of Huckleberry Finn, he uses several different themes. His themes help to portray the meaning and message of the novel. Twain's major theme in the novel is man's inhumanity to man. He develops this theme through the inhumane actions of Pap toward Huck, the dishonesty of the King and the Duke toward the Wilkes girls, and the betrayal of Jim for money by the King and the Duke. Twain uses the inhumane actions of Pap toward Huck to help develop the major theme of his novel. "' I'll take you down a peg before I get done with you'" (20). This quote shows how man is inhuman to other men, even if they are related and supposed to love each other. Pap talks and acts mean towards Huck, even though Huck is his own son. Not only is Pap mentally abusive toward Huck, but he is also physically abusive toward him. "But by and by pap got too handy with his hick'ry, and I couldn't stand it. I was all over welts"(24). The way that Pap treats Huck shows the inhumanity of man toward other men and helps to develop the major theme of the novel. The dishonesty of the King and the Duke toward the Wilkes girls also help to develop the major theme of the novel. The Duke and the King take their cruelty to another level because they steal and lie to the Wilkes girls, who are left all alone with no parents. And not sell the rest o' the property? March off like a passel of fools and leave eight or nine thous'n' dollars' worth o' property layin' around jest sufferin' to be scooped in?-and all good, salable stuff, too. (170-171) The Duke and the King are so inhumane that they will go as far as stealing from three innocent girls. "And he said of course him and William would take the girls home with them"(176). Not only do the Duke and the King steal money from the girls, but they also lie to them about bringing them to England just so they can have more money.

Chemistry of Anti-money Counterfeiting Technology Essay
I. Abstract Counterfeiting money is a big business for criminals. Nearly $70 million of fake currency gets used daily, costing consumers millions. In the present day, there are many new technologies that have been discovered and studied in order to help put counterfeiters out of business. Our currency is something that we must protect, which is why these technologies and discoveries are very important in the safety and development of our economy. The new generation of Philippine banknotes includes new and more advanced technology to ensure the safety of the genuine Philippine banknotes. This is to prevent money counterfeiting in our country. These new features include more advanced photo editing, which features micro printing on the different images and texts on the banknotes, a unique rough texture, a new system of serial numbering, advanced security fibers and security threads, watermark technology, and optically variable ink. These are the most advanced and efficient methods of preventing mon ey counterfeiting today. Provided in this paper is a detailed explanation and description of each security precaution and a detailed review of the methods used to execute them. II. Denominations of Currency The new generation Philippine banknotes composes of the denominations twenty, fifty, one hundred, two hundred, five hundred, and one thousand peso bills. The new twenty-piso bill honors President Manuel L. Quezon, the first President of the Republic of the Philippines on the front of the bill while the reverse shows the image of the breathtaking Banaue Rice Teraces and the Palm Civet from the Cordilleras. The fifty-piso bill commemorates President Sergio Osmeà ±a who led our country at the critical stage of World War II. The reverse shows an image of the Taal Lake, one of the worldââ¬â¢s smallest active volcanoes and the Maliputo Fish. The one hundred-piso bill pays tribute to President Manuel Roxas who prioritized the crafting of the Central Bank charter then provided the leadership for the reconstruction of our country after the devastation of the Second World War. On the reverse, the near perfect cone-shaped Mayon Volcano and the Butanding or Whale Shark is also featured. The two hundred-piso bill features President Diosdado Macapagal who restored the celebration of Philippine independence on June 12. The reverse features the unique icon of Bohol, the Chocolate Hills and the Tarsier. The five hundred-piso bill is a salute to the champions of Philippine democracy, Senator Benigno Aquino Jr. and President Corazon Aquino. The reverse features the Puerto Princesa Subterranean River National Park. Finally, the one thousand-piso bill features three of our war heroes, Chief Justice Jose Abad Santos, Josefa Llanes Escoda, and General Vicente P. Lim. The reverse features the Tubbataha Reefs National Marine Park and the world famous South Sea Pearl. Figure 1 The money denominations come in specific color schemes of orange for the twenty-piso bill, red for the fifty-piso bill, violet for the one hundred-piso bill, green for the two hundred-piso bill, yellow for the five hundred-piso bill, and blue for the one thousand-piso bill. III. Security Features The Philippine Banknote or the Philippine Peso Bill finds the need to be current with the use of new technology to enhance the security of banknotes to remain impossible to replicate by criminals. The new generation Philippine banknotes incorporates the latest available technology in banknote security. This is the reason that they have developed new designs and upgraded the security features of all our banknotes. A. Photo Editing The Central bank of the Philippines uses a special photo editing software to ensure specific prints that are impossible to copy by criminals. Some of these specifications include nano prints on the images, lines, and words on the banknotes. B. Texture The note is not smooth to the touch, but a bit rough. This is because the bank notes are made of 80% cotton and 20% Philippine Abaca. Aside from that, the raised prints that are embossing from the Intaglio printing process give the bill a unique tactile feel. Intaglio printing is a printing technique in which the image is incised into a surface. Normally, copper (Cu) or zinc (Zn) are used, and the incisions are created by etching ot engraving the image. In printing, the surface is covered in ink and then rubbed vigourously with tartalan cloth or newspaper to remove ink from the surface, leaving it in theincisions. The very sharp printing obtained from the intaglio process is hard to imitate by other means. Intaglio also allows for the creation of latent images, which are only visible when the document is viewed at a very shallow angle. Figure 2 C. Serial Numbers The serial numbers are composed of one or two prefix letters and six to seven digits in asymmetric or increasing size. Serial numbers are not difficult to forge; yet they make banknotes easier to track and audit. Figure 3 D. Security Fibers The paper used to print our currency has tiny threads of fibers embedded into the paper. These red and blue fibers glow under ultraviolet light. If the bill has no red and blue fibers that glow, then it is probably a fake bill. Fluorescent marks are the invisible phosphor dyes on banknotes that glow under UV or blacklight. This glow will be visible under a money detector device. There are two kinds of security fibers. The first one is the visible security fibers. These are easily seen in current Philippine banknotes as the blue and red fibers that are randomly spread throughout the front and back of the paper. The other kind is the invisible security fiber. These glow a fluorescent yellow under ultraviolet light. Genuine security fibers in Philippine banknotes can be easily plucked out (yes, try it!) with the aid of a needle. Counterfeit money usually only prints the fibers on paper, thus they cannot be plucked out. Figure 4 E. Watermarks The watermark shows a shadowed image of the portrait and the banknotesââ¬â¢ denomination on the blank space when viewed against the light from either side of the bill. This is possible due to paper density variations. Figure 5 The word ââ¬Å"Pilipinoâ⬠, written in our ancient Filipino alphabet, Baybayin, can be seen in its complete form when the banknote is viewed against the light. F. Concealed Value When the banknote is rotated at a 45-degree angle and tilted downwards, we can see the concealed denominational value super imposed on the smaller version of the portrait. Figure 7 G. Security Threads Both the twenty-piso and the fifty-piso have a 2mm wide security thread that can be visible when viewed against the light. The one hundred, two hundred, five hundred, and one thousand-piso bills have a 4mm wide stich-like security thread embedded on the bill and when viewed from different angles, its color changes from red to green. The embedded security thread is a special thread vertically implanted off center of the note during the manufacture of the banknote paper. The front of the thread carries a clear text ââ¬â the initials of the Bangko Sentral ng Pilipinas (BSP) and the numeric denomination of the bank note. The back of the thread is also printed with the initials BSP. There are two kinds of security threads. One is a thin aluminum (Al) coated and partly demutualized polyester film thread with microprinting, which is embedded in the security paper as banknote or passport paper. The other kind of security thread is the single or multicolor sewing thread made from cotton or synthetic fibers, mostly UV fluorescent, for the bookbinding of passport booklets. Figure 8 H. Optically Variable Device Patch The five hundred-piso bill and the one thousand-piso bill have the optically variable device patch, a reflective foil. For the five hundred-piso bill, it reveals the small BSP (Bangko Sentral ng Pilipinas) logo and the blue parrot, while the one thousand-piso bill reveals the small BSP logo and the South Sea Pearl inside a clam. The patches change color from red to green when the note is rotated 90-degrees. Figure 9 I. Optically Variable Ink A security feature exclusive to the one thousand-piso note is the optically variable ink for the embossed denomination value on the lower right corner on the face of the banknote, which changes color from green to blue when it is viewed in different angles. Color changing inks are inks containing pearlescent pigments that change color when viewed at a different angle. The color of the ink does not actually change, but the angle of the light to the viewerââ¬â¢s eye changes and thus creates the change in color. A number of types are available, including green to purple, gold to green and green to lilac. Optically variable inks (OVI) are very expensive inks applied on banknotes as a security feature. So far, only the 1000 peso bills have this. There are two versions of OVI printing on the 1000 peso banknotes. This is an excellent security feature because counterfeiters will need a lot of effort and money to replicate it. They are called optically variable inks because tiny flakes of color-shifting film are incorporated in the intaglio ink. Thus, prints of OVI change color when viewed from different angles.
