His lyric shows the blessing, inventiveness, and society of the dark group and how they are as equivalent as white individuals. This title is critical in light of the fact that like a raisin in the sun, their dreams go away, they spoil like meat and rot like flies. They go away like a raisin in the sun on the grounds that they all have these particular dreams and they all need to attain these objectives yet they all realize that the likelihood they had always wanted really working out as expected are extremely thin on account of their race and their absence of riches.

Language Arts - 1055 Words

Language and Art share many similar tendencies. In language, as with earlier forms of Art, representation plays a large role. Language acts as a representation of some elaborate envisioned concept(s), Writing as a representation of a sounded phonic language, and Art as a representation of some subject(s). Within these mediums exist elements that make Art and Language and, by extension, Writing successful. î  ¢ese are the signifiers. î  ¢e signifiers are built imperfectly, they summon up signs other than those intended based on frequency of usage, misusage and place contextually. î  ¢ey are influenced by a multitude of extra-textual forces. It is from these axioms, that Structuralism and thence, Deconstructivism take form. Jacques Derrida†¦show more content†¦Ã®  ¢e essence remains ‘wanting’ and exists always in some transcendental plane. Art and Philosophy aim to defamiliarise the viewer or reader to some established norm. Philosophy aims to describe things that are fundamental nature of ’knowledge, existence and ethics’ (Webster’s Online Dictionary), things that are inherently difficult to explain in plain language. It is only through a complex system of resonance between signs that philosophy can be successful and hone the right tone of capturing a desired essence. î  ¢e abandoned sired signs are leî‚  to the side, defamiliarised and alienated to yield a complete perception of one concept at the sacrifice of several.

All of his references that he †sacrifices† to produce a value of diffà ©rance are outside and pre-produced. In the same vein, Art wishes to hone the viewer’s attention to some smaller aspect of the larger canvas or something completely outside. Take Picasso’s 1937 painting La Guernica, the aesthetic aim was for the signifiers (the magnified Cubist heads) to signify the terror of the Spanish Civil War, an action completely extra-textual.

A Comparison Of Faith And The Future Of Religion - 1539 Words

A Comparison of Faith Faith, defined as a strong belief in something which cannot be proven, has been argued over countless generations. Still, even without proof, individuals worldwide hold true to their faith each day. After studying faith and religion in texts written by scholars with varying backgrounds, it is easy to see faith is something which is widely disputed. Comparison of Sigmund Freud’s The Future of an Illusion and Paul Tillich’s Dynamics of Faith, fully displays the discrepancies in points of view on the function of faith, as well as the necessity of faith, in society; while the comparison of Viktor E. Frankl’s Man’s Search for Meaning and Karl Marx’s â€Å"on the Future of Religion,† demonstrate both similarities and differences†¦show more content†¦Throughout his book, Tillich references faith as an ultimate concern to emphasize the importance of faith in the personality of individuals. Furthermore, Tillich believes faith is a vital part of human nature and that even the rejection of faith is, in itself, an act of faith. This displays Tillich’s understanding that faith will never disappear from society because it is a piece of the puzzle in what makes up humanity (Tillich). After summarizing both arguments, discernibly Sigmund Freud and Paul Tillich would hold opposing views on both the function of faith and the future of faith. The disagreement would begin with the function of religion in society, displayed when Tillich writes, â€Å"The question raised by this book is whether such belief is based on insight or on misunderstanding, and the question is unambiguously that the rejection of faith is rooted in a complete misunderstanding of the nature of faith† (146). Freud believes religion is man being immature, but Tillich feels differently. Tillich perceives the rejection of faith as the misunderstanding of the true nature of faith. If Tillich and Freud were to hold a debate, Tillich would most likely discuss how Freud misunderstands faith’s nature. Freud, however, would respond with a discussion about how faith is man looking for security in the world.Show MoreRelatedIslamophobia: Muslims and Terrorism1162 Words   |  5 Pagesviolent t errorist acts.

Recently, There are some personal reflections a great learning experience in the course of risk management of international business. I would like to share in this journal. It has been a long time since I defined the most fundamental and strong motivation of corporations is maximizing business profit. Even after the proposal of corporation social responsibility, I assumed that only the result of unharmed business operation can make company start to consider social responsibilities and until they increased their profits they will remain no more than a bystanders from external issues be it social or environmental. However the fact should be noticed is that nowadays more and more company started showing commitment to CSR, making investment decisions though ESG framework, labeling their products with FIO (Fairtrade Labeling Organization) and other measures that can benefit for the publics. Interestingly, most of the time public interests are conflict with profit maximization. Also when it comes to international businesses, the issue of sacrificing social interests to satisfy business ambition is even larger and more complex. For instance, in order to reduce the material cost, lots of MNCs like Nestlà © purchased palm oil in Indonesia, which speeded up deforestation there, leading to extinction or near extinction of some creatures once lived there such as Orang Utan.

[ 1 ] The being of ultrasound was foremost noticed by Lazzaro Spallanzani in 1794. Since so, ultrasonics, the survey of sound propagated at frequences beyond the scope hearable to people ( i.e. above 20 kilohertz ) has been a new topic. [ 2 ] The existent discovery took topographic point after that Pierre and Jacques Currie discovered of the â€Å" Piezo-electric Consequence † in certain crystals in 1880. This led to the development of ultrasound transducer. [ 1 ] The possibility of the usage of an supersonic reverberation method for the sensing of submersed obstructions at sea, such as icebergs or wrecks, appears to hold been suggested by L.F. Richardson at the clip of the Titanic catastrophe in April 1912. After the 1914-1918 War the piezoelectric effect and its reverse consequence were foremost successfully applied in the sensing and coevals of ultrasound. The original application was to the sensing of enemy pigboats. And a feasible system was developed by P. Langevin. A beam of ultrasound is propagated vertically downwards in the sea, is reflected at the sea bed, or by some other object such as a pigboat above the sea bed, and returns to the generator/detector. By entering the going of the original pulsation and the reaching of the reverberation, the theodolite clip T for the return journey over a distance of 2d can be determined. Therefore, presuming the velocity degree Celsius of ultrasound in sea H2O is known, the deepness vitamin D can be calculated from. [ 3 ] In 1935, the rule of supersonic sensing was applied into wireless sensing and ranging, utilizing electromagnetic moving ridges alternatively, which called Radar besides. [ 2 ] However, the development of radio detection and ranging, during the Second War, resulted in many betterments in electronic engineering. These developments in bend wholly revolutionized the sensing system by presenting the possibility of utilizing arrays of transducers, enabling sector-scanning to be introduced, and by bettering ocular show systems. [ 3 ] 1.1.2 Review of background research A distance sensor, besides called as a scope happening setup is one installing that determines and detects the distance between the mark and the sensing device, for the intent of appraising, finding focal point in picture taking, or accurately taking a arm. Some devices are applied utilizing active methods to mensurate ( such as ultrasound, optical maser, or radio detection and ranging ) , while others obtain the mensural distance utilizing trigonometry ( stadia metric scope finders and parallax, or cut-image scope finders ) . These methodological analysiss use a set of known information, normally distances or mark sizes, to do the measuring, and have been in regular usage since the 18th century. [ 1 ] Since distance measuring has played an of import function in no affair the day-to-day life or working sphere, assorted types of range finders have been created to run into a assortment of demands. These device types vary each other harmonizing to their public presentation in different fortunes, every bit good as the cost, where public presentation is determined by truth, easiness of usage, sensing scope, etc. [ 4 ] In recent yearss, three chief types of distance sensing faculty are 1s utilizing infrared, ultrasound and laser severally. Hereinto, scanning supersonic sensing system is the type utilizing supersonic detectors. Supersonic detectors are normally used for non-contact, propinquity or distance measuring applications. These devices typically transmit a short pulsation moving ridge to the mark, which reflects the sound back to the supersonic detectors. The system so mensurate the echo clip of the moving ridge returning to the detector and work out the distance to the mark with the velocity of sound. [ 5 ] The basic regulation for the usage of ultrasound as a measuring tool is the time-of-flight technique, of which this pulse-echo method is one illustration. As shown in figure 1. Figure 1. Basic Illustration Of Ultrasonic Detection — Transducer Generates Ultrasonic Waves And Then Listens To Repeat Therefore, the rule of supersonic sensing system is given as followers: If the speed of supersonic moving ridges extension has been known, mensurate the period between the clip of its launch and contemplation back from an obstruction, so that the practical distance between launch point and obstruction can be determined, which is similar to the rule of radio detection and ranging. Frequently, the equation is given as: . ( 1 ) Where, d represents the magnitude of distance, C equals to supersonic extension speed in the air and T is the time-lag which normally amounts to the entire clip from launch and response. You read "Scanning Ultrasonic Detection System Engineering Essay" in category "Essay examples" [ 6 ] 1.2 The Requirement for Ultrasonic sensing system In recent yearss, there are assorted types of distance measurement detectors, like infrared, supersonic and optical maser range finders. They differ each other in tonss of facets: truth, scope, size, weight etc. Infrared Supersonic Laser Accuracy Typically 0.1m Typically at centimeters Typically at millimeters Detection moving ridge Electromagnetic moving ridge ( unseeable radiation ) Sound wave Electromagnetic moving ridge ( several sorts ) Costing i6.83 ~ i17.89 [ 7 ] i9.99 ~ i70.79 [ 8 ] i870 ~ i3485 [ 9 ] Usual usage juncture Small refractile index ( go through other stuff ) , good for long distance sensing [ 10 ] Insensitive to dust, soil and fog, good for utilizing under serious environment state of affairs [ 11 ] High preciseness, good for high-accuracy demand state of affairs [ 12 ] Problems Low preciseness, worse way control [ 10 ] Preciseness influenced by temperature, humidness, force per unit area etc. [ 11 ] Not safe to human in some state of affairs, optical system must be clean to observe [ 12 ] Table.1: Comparison among Three Types of Detection Systems Using Infrared, Ultrasound and Laser Respectively Harmonizing to the tabular array above, the infrared detectors have cheaper monetary value and shorter response clip than supersonic detectors, but have hapless preciseness, way control and rely strongly on good coefficient of reflection belongingss. In footings of optical maser scope finder, it owns high preciseness but besides has high monetary value and hard operating, in common instances it is used in military kingdom. In the usual instances, the supersonic sensor is more equal for day-to-day utilizing or extended utilizing for industrial or societal occasions for its moderate monetary value, stable capableness and acceptable truth. The lone job for supersonic sensing system is its preciseness in some particular occasions like remote-controlled cars or endorsing for autos which require more cherished distance consequences. 1.3 Error Analysis of Ultrasonic Detection and Scanning System For the intent of the supersonic sensing and scanning system, supersonic is one of the active countries of research and development. Supersonic detectors are good known for their public presentations in debatable environment where other detectors are non capable to be used. The rule is based on time-of-flight ( TOF ) theory, as illustrated antecedently, the clip of flight is the period of clip that travelled to and bounced back from the mark object. Use the look ( 1 ) , the distance can be determined. However, the extension speed of supersonic moving ridge is affected by the temperature, force per unit area, humidness, air turbulency and gas composing. But the most of import factor that affects the sound velocity is the temperature. The approximative velocity of sound in dry ( 0 % humidness ) air, in metres per second ( ) , at temperatures near 0 A °C, can be calculated from: ( 2 ) Where I? is the temperature in grades Celsius ( A °C ) . [ 13 ] Give the undermentioned fluctuations in the velocity of sound utilizing the criterion ambiance. As shown in table 2 below. Temperature ( A °C ) Sound velocity ( m/s ) -20 318.89 -10 325.16 0 331.30 10 337.33 20 343.26 25 346.18 30 349.08 Table.2: Relationship between Temperature and Sound Speed So for a sensing system that does non hold temperature detector, if the practical distance is 3m, the clip of flight distance is 6m. And presume ever to utilize the velocity value at temperature 20 A °C, which is 343.26 m/s. But in fact, when the temperature alterations, the practical velocity of sound value can besides be different. Assume the temperature changes into -10 degree Celsius, and so harmonizing to the table.2, practical velocity of sound is 325.16 metres per second, that is, the practical mensural clip of flight should be . But if the microcontroller still uses the sound velocity at 20 A °C, practical measured distance could be , This outputs mistake. That is to state, in this instance, under temperature -10 grade Celsius, one metre long distance may hold about 5.57 centimeters mistake, which is a comparatively large mistake in some alone juncture such as remote-controlled vehicle or the unsighted pilotage and will ensue in serious jobs. Because of that, a temperature compensation step should be taken to heighten the truth of this supersonic distance sensing system. 1.4 Previous Work There are many supersonic distance metres in markets, having different features.

[ 17 ] Be possible to be applied into echography, to expose graph on the proctor ( by taking advantage of some specific package ) . [ 18 ] In the practical application of counsel for wheeled little auto or automaton, the whole system should be installed onto the bearer, frequently with a switch and battery to command and drive it. Put the supersonic detector onto the rotary motion motor, to do the supersonic detector detect object in a sector, here from 0 grade to 180 grade. Once bend on the system, the microcontroller starts to give directives to the rotary motion motor to do it revolve to the initial angle, 0 degree way. And so do the supersonic starts to run, bring forth supersonic moving ridges and so listen to the reverberation. Harmonizing to the signal moving ridges received from the supersonic detector, the microcontroller starts to cipher the distance value, taking proper velocity of sound value by utilizing the temperature compensation measuring. After the computation is done, the values are transmitted into LCD and show on it to state the obstruction distance at relevant angle and temperature. Each clip when the objects on the way at cherished angle have been detected or there are no objects, the microcontroller will give directives to do the rotary motion motor rotate into the following angle. For case, each clip the rotary motion motor is ordered to revolve 20 grade, ab initio, it starts from 0 grade, when the sensing on this way has been do ne, it rotate 20 grade, once more to make the sensing, and following, it rotate 20 grade into the way of 40 grade, to make the sensing, as the entire 9 times rotary motion is done, the rotary motion motor turns back into its initial angle 0 grade to re-start the sector scanning sensing. Here is a flow chart to demo the system work processs: The initial way Detection objects Calculation and temperature compensation Display informations on LCD Rotate angle ( illustration as 20 grade ) The followers are the same as earlier. Each clip the sensing is done, revolve another 20 grade. After entire nine times rotary motion, the rotary motion motor attached under supersonic detector returns back into the initial place. Harmonizing to the information detected, it is possible to be used for the wheeled auto or automaton to make up one’s mind where to travel and how to avoid obstructions. 3 Aims 3.1 Major Aims Design a system which detects the presence of objects utilizing a revolving supersonic scanner. The power of micro chip, LCD, rotary motion motor, supersonic detector and temperature detector is supplied by 5V beginning. The frequence to drive the supersonic detector should be 40 kilohertz. Once the power is on, the microcontroller will enable the supersonic detector to bring forth moving ridges. And the feedback signals will be transmitted back to the microcontroller for processing. Once the echo signal is processed, the temperature detector will offer temperature compensation for sound velocity. After power is on, the rotary motion motor is driven to initial angle place and starts to revolve from 0 grade to 180 grade, rotate one time by a certain angle when each clip the sensing is done. Each clip the sensing is done, the LCD will expose the information about it including distance, temperature and comparative angle, like â€Å" 86.5cm 23a„? 90A ° â€Å" . Once the sensing is done, the information will be transmitted to computing machine and show on the proctor utilizing hyperterminal package.

Imitate the map and run into the major aims utilizing relevant package. 4 Main Components 4.1 Ultrasonic Sensor There are some sorts of supersonic detectors. The chiefly used two theoretical accounts are SRF04 and SRF05 because their comparative lower monetary value and moderate public presentation. Here is a comparing between them. SRF04 Voltage: 5V merely needed Current: 30mA typical 50mA soap Frequency: 40 kilohertz Scope: from 3cm to 3m. Sensitivity: 3cm at 2m, 1.5 % Input trigger: 10 uS Min. TTL degree pulsation Echo pulsation: positive TTL degree signal, width proportional to run Small size: 43mm x 20mm ten 17mm tallness Monetary value: i14.50 ( Inc. VAT i17.40 ) SRF05 Voltage: 5V merely needed Low Current: 4mA Typical Frequency: 40 kilohertz Max Range: 4m Min Range: 1cm Mode1: Single pin for trigger/echo Mode2: 2 Pin SRF04 compatible Input Trigger: 10uS Min. TTL degree pulsation Echo Pulse: Positive TTL signal Size: 43 x 20 ten 17h ( millimeter ) Monetary value: i11.50 ( Inc. VAT i13.80 ) Table.4: comparing between two supersonic detectors Comparing the characteristics of two supersonic detectors, they are all capable to complete this undertaking. But eventually the determination is made to SRF05. And the grounds are listed as followers. Although they portion the equal electromotive force demand, SRF05 merely require much lower current. Therefore, utilizing SRF05 will necessitate smaller power to drive. It is more energy-saving. They both need 40 kilohertzs to drive, which meet the demand of this undertaking. But SRF05 has a scope from 1cm to 4m, which is larger than SRF04, whose scope is 3cm to 3m. For the demand of more accurate and larger-scale sensing, the SRF05 is better for this undertaking. SRF05 has two manners for taking, one is single-pin for both trigger and reverberation, the other one is compatible to SRF04, two-pin for trigger or reverberation. So SRF05 can salvage 1 pin if usage mode1, but besides be used as SRF04 if usage mode2. Harmonizing to the monetary value listed, SRF05 has a lower monetary value than SRF04. 4.2 LCD Module In this undertaking, the LCD is used for exposing information of obstructions and environment in environing country. Harmonizing to this, the demand of LCD faculty should be: The LCD faculty is capable to expose numerical values, English alphabets and some measurement units. The LCD screen is large or long plenty to demo full information. The LCD screen should be seen in dark topographic point so it may hold a backlight map. The LCD faculty does hold interface to microcontroller for their transmittal. The LCD faculty is easy to run. The LCD should hold a comparatively inexpensive monetary value. Harmonizing to the demands, here is the determination: VERBOUQUET -ALPHANUMERIC, 2X16, STN LCD MODULE, Here is the specification of this LCD faculty: LCD MODULE, ALPHANUMERIC, 2X16, STN No. of Digits / Alpha: 32 Character Count x Line: 16 tens 2 Character Size: 5.56mm Supply Voltage: 5V Display Mode: Brooding Display Area Width: 64.5mm Display Area Height: 16mm Operating Temperature Range: 0A °C to +50A °C External Depth: 10mm External Length / Height: 44mm External Width: 84mm Active Area Height: 16mm Active Area Width: 64.5mm Background Colour: Yellow Fictional character Height: 4.86mm Character Type: Dot Matrix + Cursor Character Width: 2.96mm Connector Type: B, 1 ten 14 Display Polarization: Brooding Display Technology: STN Font Colour: Green Interface Type: Analogue No. of Colours: 1 No. of Digits / Alpha: 16 No. of Lines: 2 Resolution: 5 x 7 Dots + Cursor Storage Temperature Max: +70A °C Storage Temperature Min: -20A °C Supply Voltage Max: 6V Supply Voltage VDC: 5V Monetary value: i7.06 Table.5: specification of selected LCD faculty 4.3 Rotation Motor In this undertaking, the rotary motion motor should run into there demands: The microcontroller straight controls the rotary motion motor to revolve and make up one’s mind the angle value. The rotary motion motor has the shaft to be installed on with supersonic detector. The truth demand to be ensured. The monetary value is non high. Compared to these demands, here are two types of motors: hoofer motor and servo motor. Here is a comparing between these two types utilizing typical theoretical accounts: Stepper motor Bipolar 48mm Stepper Measure Angle: 0.9A ° Measure Accuracy: 5 % Keeping Torsion: 4800g-cm / 66.66 oz-in Coil Resistance: 10hm Rated Current: 2.4A Motor Length: 48mm Mounting Plate Size: NEMA-17 Shaft Diameter: 5mm Weight: 362g Number of Leads: 4 Monetary value: i14.55 Servo motor Parallax ( Futaba ) Standard Servo Holds any place between 0 and 180 grades 43.1 oz-in torsion at 6 V Accepts four mounting prison guards High preciseness cogwheel made of the POM ( polyacetal ) rosin makes the operation smooth doing no recoil Power Requirements: 4 to 6 VDC Communication: Pulse-width transition Dimensions: 2.2 x 0.8 ten 1.6 in ( 55.8x 19 ten 406 millimeter ) excepting servo horn Operating temp scope: +14 to +144 A °F ( -10 to +50 A °C ) Monetary value: i10.79 Table.6: comparing between typical hoofer motor and servo motor Harmonizing to the comparing, it can be concluded that the servo motor is more appropriate for this undertaking because these grounds: When servo motor receives a pulsation, it can end product a pulsation back to the microcontroller to give feedback, which is good to command the truth of the angle. Its truth can maintain up to 0.001mm, more precise than stepper motor. Servo motor can revolve an angle harmonizing to the pulsation transmitted from microcontroller within several msecs. But stepper motor can merely steps to the needed angle, frequently it will take 200~400 msecs. Servo motor has a lower monetary value than stepper motor. So, the determination is made to the servo motor, in this undertaking, utilize Parallax ( Futaba ) Standard Servo Motor for its standard public presentation and low monetary value. 4.4 Temperature Sensor The temperature detector should hold some demands: High truth to do certain of the preciseness of this undertaking.

Need for ADC Yes No Resolution spots 10 12 Costing Sensor + Op-amp + variable resistors=i4.47 Merely sensor=i3.27 Table.8: Comparison between Analogue and Digital Sensing System In the table.8, the costing values are all based on the values and monetary values shown at Farnell website. Analogue detector LM35DZ, Op-Amp CA3140, variable resistances and digital detector DS18B20 are i1.29, i1.67, i1.51 and i3.27 severally. Conclude the information given by the table.8, a simple and natural decision can be given that digital detector DS18B20 is somewhat or unusually superior to the parallel one. 4.5 Microcontroller The microcontroller is the cardinal bosom of the whole undertaking system, but there are many types of microcontroller.

Show in Figure.8 and Figure.9. Figure.8: PCB design manner Figure.9: PCB design Real World Mode Real Picture Figure.10: existent image 5.1 power supply In this undertaking, all the devices are based on 5V power supply. However, most common batteries do non back up this electromotive force value. So use 9V battery and electromotive force regulator to give a 5V electromotive force beginning. Besides, here can add a switch to command the whole system to turn on or turn off. Because it is needed to give a 5V beginning, so the electromotive force regulator determination is made to LM7805. Here is the diagram for the power supply. c†Ã‚ µe ·?a†º?aˆ‚ Figure.11 schematic for power supply faculty 5.2 Ultrasonic Sensor Module The supersonic detector faculty has two manners to take. Mode 1: 2-pin Trigger/Echo Mode This manner uses separate trigger and reverberation pins, and is the simplest manner to utilize. All codification illustrations for the SRF04 will work for the SRF05 in this manner. To utilize this manner, merely go forth the manner pin unconnected – the SRF05 has an internal pull up resistance on this pin. Figure.12: connexions for 2-pin Trigger/Echo Mode In this manner, the timing diagram is: Small hold Figure.13: SRF05 clocking diagram for manner 1 Here, the SRF05 includes a little hold before the reverberation pulsation to give slower accountants such as the Basic Stamp and Picaxe clip to put to death their pulsation in bids. Mode 2: Single pin for both Trigger and Echo This manner uses a individual pin for both Trigger and Echo signals, and is designed to salvage valuable pins on embedded accountants. To utilize this manner, connect the manner pin to the 0v Ground pin. The echo signal will look on the same pin as the trigger signal. The SRF05 will non raise the echo line until 700uS after the terminal of the trigger signal. You have that long to turn the trigger pin around and do it an input and to hold your pulsation mensurating codification ready. The PULSIN bid found on many popular accountants does this automatically. Figure.14: connexion for individual pin trigger/echo manner In this manner, the timing diagram is: Figure.15: SRF05 clocking diagram for manner 2 In this undertaking, for there are 33 I/O pins for usage, there is no demand to utilize manner 2, so here use Mode 1 which is compatible to SRF04.

Belonging- Memoirs of a Geisha free essay sample

The 2005 film ‘Memoirs of Geisha’, directed by Rob Marshall, is a film which follows the life of a young Japanese girl who is taken from the life of which she was accustomed to and is forced to live in and become part of a world which is exceedingly isolating, restricting and where conformity is highly valued. Sayuri, the protagonist in the film, finds that the only way for her to overcome her feelings of disconnectedness and isolation is to actually intentionally isolate and disconnect herself from her desires, love, emotions, and ultimately herself. The film introduces the idea of acceptance as being a key feature of achieving happiness. Those who are desperately searching for recognition from others are willing to give up control of their own lives in order for them to personally achieve happiness. This is evident in a particular scene in the film when Sayuri meets her purpose in life, General Tanaka. We will write a custom essay sample on Belonging- Memoirs of a Geisha or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page After showing her kindness and understanding, Sayuri felt she could possibly find a connection with this new world and potentially find happiness for herself, â€Å"in that moment, I changed from a girl facing nothing but emptiness to someone with purpose†. In this scene, and throughout the entire film, Sayuri’s voice is heard as a voice over as she is retelling her story, effectively narration. It implies that the story is a personal experience and so it allows the audience to feel a sense of empathy towards the character as the narration makes it easier for the audience to relate her experiences and emotions to their own personal lives. Sayuri is seen running through, what seems to be, an endless tunnel of large wooden posts. A follow shot is used, when the character is seemingly pursued by the camera, which assists in making the tunnel feel as though the character is running away. Metaphorically, she could be running away from her past feelings of disconnectedness, isolation and unhappiness. A panning shot is also used to the roof of the tunnel. This causes a claustrophobic affect and makes Sayuri look as though she is trapped from the outside world. The colours used are incredibly confronting, bright red and black, and draws attention from Sayuri running through them. They could possibly represent the challenges that Sayuri must confront in order to achieve her desires, the most significant was to become a geisha, â€Å"to be a geisha could be stepping stone to something else, a place in his world†. This is ironic because being a geisha is incredible isolating as it is dangerous to form a close connection with anyone, yet it is her way to become a part of something. Individuals can find and feel acceptance and connectedness through gaining recognition from someone whom they desire it from. In order for Sayuri to feel a sense of security and comfort, she must seek recognition from General Tanaka; however, in the society she lives in, she must be accepted by others in the community to achieve this recognition. One scene in particular which presents this is when Sayuri performs a traditional Geisha dance in front of a highly regarded audience. This dance signifies her official Geisha status which is one step further towards achieving her goal. The dance is extremely overpowering, intriguing and is full of emotion and passion. At the conclusion of the scene, the camera pans over the audience to show their reactions of joy and pleasure. This shows that those within her community have accepted her and are welcoming. General Tanaka reacts along with the crowd, â€Å"you were wonderful tonight†, which encourages Sayuri to continue to pursuit her goal. Blue lighting is used to create a magical and mysterious tone and this draws attention to Sayuri as it highlights her figure. Diegetic sound is used as traditional Japanese music is being played by the orchestra. This contributes to the feelings of mystery and also adds culture as traditional instruments are used. A close up is used to show the emotion that Sayuri is portraying. This gives the audience an idea of the emotions that she is feeling and how immersed she is in what she is doing, showing her determination to succeed. The colours used are mostly colours of purity and innocence such as white and pale blue. This is contrasted with Sayuri’s pitch black hair and the strips of red on her gown could represent strength and power.

Veterinary Terminology and Homeostatic System †Free Samples

Question: Discuss about the Veterinary Terminology and Homeostatic System. Answer: Homeostasis (Meaning, the body systems that controls homeostasis, what is negative feedback system, homeostatic mechanisms) Definition: Homeostasis can be understood as a self regulating system which allows the maintenance of stability in biological systems, while adjusting to condition vital for survival. The stability is a state of dynamic equilibrium where a uniform set of conditions are maintained through continuous sets of changes (De Luca et al., 2014). Body Systems Involved in Homeostasis: Homeostatic system consists of three components: receptor, control and effectors. The control can either be intrinsic or extrinsic. The Endocrine and the nervous system mostly act as control systems for homeostasis. (estrellamountain.edu, 2018). Negative feedback system Negative feedback system refers to a system where the information provided by the feedback causes a change that is reverse to the response (estrellamountain.edu, 2018). Homeostatic control systems: Different types of variables are controlled by the homeostatic mechanism. These include: core body temperature, blood glucose, levels of respiratory gases in blood, blood oxygen levels, arterial blood pressure, level of calcium, concentration of sodium, concentration of potassium, fluid and osmotic balance, pH of blood, composition of cerebrospinal fluid, neurotransmission, neuroendocrine system, regulation of gene expression and energy homeostasis (Nakamura, 2011; Prabhakar Semenza, 2015; bbc.co.uk, 2018). Hyperadrenocorticism and Hypoadrenocorticism Hyperadrenocorticism Hypoadrenocorticism Definitions Hyperadrenocorticism is also called the Cushings Syndrome, characterized by a chronic excess of systemic cortisol (Lunn, 2018; Greco, 2018). Hypoadrenocorticism is also known as Addisons Disease characterized by a deficiency of adrenocortical hormones (Bruyette, 2018; Klein Peterson, 2018). Excessive and deficient conditions Excess cortisol level Deficient cortisol levels Cause Pituitary dependant Hyperadrenocorticism, Adrenal Tumor and Iatrogenic Hyperadrenocorticism. (Lunn, 2018; Vetfolio.com, 2018) Caused due to the destruction or atrophy of the three adrenal cortical layers thereby resulting in the inadequate secretion of glucocorticoids and minerelocorticoids (Klein Peterson, 2018). Clinical Signs Polyphagia, Polyuria/Polydispsia, abdominal enlargement, weakness of muscle, panting, Lethargy, Panting, Alopecia, Intolerance to heat, Calcinosis cutis, Comedones, Thin skin, bruising, striae, Hyperpigmentation, Testicular atrophy, Pseudomyotonia, Anestrus, Seborrhea, pyoderma and Facial paralysis (Lunn, 2018). Chronic gastroenteritis, changes in serum levels of potassium, sodium and chlorine; Hyponatremia; hypochloremia; Severe hyperkalemia; bradycardia; cute circulatory collapse; renal failure; hypotension; weakness; microcardia; progressive dehydration; hemoconcentration; Emesis; diarrhea; anorexia; weight loss; hypoglycemia; and skin hyperpigmentation (Bryutte, 2018; Klein Peterson, 2018). Diagnosis Urine cortisol to Creatinine ratio; Adrenocorticotropic stimulation test; intravenous low-dose and oral dexamethasone suppression test; high-dose dexamethasone suppression test and Measurement of endogenous plasma Adrenocorticotropic concentrations (Greco, 2018). Complete Blood Count, Serum Biochemistry, Urianalysis. Diagnostic imaging techniques like: Abdominal radiograph, thoracic radiograph, abdominal ultrasound exam, brain CT scan or Magnetic Resonance Imaging (Lunn, 2018). The condition can be diagnosed on the basis of compatible history, clinical signs, laboratory abnormalities, imaging studies and adrenocorticotropic hormone stimulation test results. Diagnostic imaging can include: thoracic radiograph, abdominal ultrasonography, electrocardiogram (Lottati Bruyette, 2018). Treatment Surgical Intervention for adrenocortical tumours or pituitary tumours. Medical therapy: mitotane, trilostane, ketoconazole and l-deprenyl (vetfolio.com, 2018; Lunn, 2018). Acute medical emergency is needed for adrenal crisis. The treatment should include: intravenous drip of saline solution; prednisolone sodium succinate or dexamethasone sodium phosphate (for shock); prednisone or prednisolone; minerelocorticoid replacement therapy; regular monitoring of renal function, electrolyte and glucose levels; administration of insulin (Bruyette, 2018). Whether common in canine/feline/both Canine Canine Hypercalcemia and Hypocalcemia Hypercalcemia Hypocalcemia Definitions Hypercalcemia occurs when the concentration of serum calcium is more than 12mg/dL or ionized calcium is greater than 1.4mmol/L (Nelson, 2018). This condition is characterized by low levels of calcium in blood due to vitamin D inadequacy, hypoparathyroidism or resistance to these hormones (Fong, 2012). Excessive and deficient conditions Excessive concentration of serum calcium or ionized calcium (Nelson, 2018). Deficient levels of serum calcium Cause Acromegaly, adenocarcinoma of apocrine gland, Carcinoma, Iatrogenic disorders, Hypoadrenocorticism, Idiopathic hypercalcemia of cats, Lymphoma, Multiple myeloma, Metastatic or primary bone neoplasia, Primary hyperparathyroidism, Skeletal lesions and myeloproliferative disease (Peterson, 2018). Renal disease, hypoproteinemia, pancreatitis, puerperal tetany, Phosphate Enema Toxicity (Peterson, 2018). Other causes include: Eclampsia, Hypoparathyroidism, and Certain types of poisoning, rickets and blood transfusions (Lee, 2018). Clinical Signs Polyuria/Polydispsia; anorexia, vomiting, constipation, pancreatitis, tranguria/pollakiuria, mental dullness, obtundation, coma, twitching, shivering, seizure, muscular weakness, lymphadenopathy, mass in the rectal wall, mammary masses, chronic renal failure, bradycardia with weak femoral pulses (Harkin, 2018). Muscle cramps, diffuse encephalopathy, Papilledema, hyperreflexia, tetany, laryngospasm and generalized seizures; brittle nails, coarse hair, dry and scaly skin and cataracts (Lewis 2018). Diagnosis Septum Parathyroid hormone test, Ultrasonography of parathyroid glands, and explorative surgery (Peterson, 2018). Estimation or measurement of ionized calcium, magnesium, phosphate, parathyroid hormone, alkaline phosphatase, vitamin D in blood measurement of phosphate and cAMP in urine (Lewis, 2018). Treatment Fluid therapy, glucocorticoid administration, Diuretics and miscellaneous agents like: bisphosphonate, mithramycin, Calcimimetics and calcitonin (Peterson, 2018). Intravenous calcium gluconate for tetany, Oral calcium for postoperative hypoparathyroidism and Oral calcium and vitamin D for chronic hypocalcemia (Lewis, 2018). Whether common in canine/feline/both Both Both Hyperthyroid and Hypothyroid Hyperthyroidism Hypothyroidism Definitions Hyperthyroidism or Graves disease caused by an overactive thyroid gland, therefore resulting in an increase in thyroid hormones secretion (Medlineplus.gov, 2018). Hypothyroidism is caused by an underactive thyroid gland resulting in the undersecretion of thyroid hormones (ncbi.nlm.nih.gov, 2018). Excessive and deficient conditions Excessive thyroid hormone production Insufficient levels of thyroid secretion Cause It can be caused due to increased production of thyroid hormones (T3 and T4) from enlarged thyroid gland. The enlargement can be due to an adenoma (non-cancerous tumor) or thyroid adenocarcinoma (malignant tumors) (Komreich, 2018). The most common cause is Lymphocytic thyroiditis and idiopathic atrophy of the thyroid gland (Peterson, 2018). Clinical Signs Weight loss, increased appetite, thirst and urination; vomiting, diarrhea, hyperactivity; unkempt/matted/greasy appearance of fur coat (Komreich, 2018). Other signs may include: restlessness, aggressiveness, rapid heart rate, difficulty breathing, weakness and depression (vetmed.wsu.edu, 2018). Common signs may include: Hair loss, weakness, lethargy, slower heart rate, and drop in body temperature, mental dullness and obesity. Other symptoms may include Cushings syndrome Diagnosis Checking the thyroid gland for enlargement (by palpating); checking the heart rate and blood pressure; measurement of thyroid hormone in blood; evaluation of general health, urinalysis, monitoring the function of kidneys and heart (Kornreich, 2018). Measurement of the concentration of thyroxin in blood; Thyrotropin releasing hormone TRH and thyroid stimulating hormone TSH stimulation tests; Scintigraphy and ultrasonography of the thyroid gland. Other tests include: modified equilibrium dialysis test used along with TSH measurement test (Peterson, 2018). Treatment Treatment can be in the form of medication, radioactive iodine therapy, surgery and dietary therapy. Medication can include: anti thyroid drugs, while surgery includes removal of thyroid gland and dietary therapy can include limiting dietary iodine intake (Kornreich, 2018). Intravenous levothyroxine (for dogs in myxedema coma); Medications include: levothyroxine (oral); liquid thyroxin. Follow-up should be done to monitor the condition and to check for complications (Lathan, 2018). Whether common in canine/feline/both Feline Canine Diabetes Mellitus Diabetes Mellitus is a disease that is characterized by consistently high levels of blood glues, and a reduction in the secretion of insulin or infectivity of the insulin hormone on the tissues of the body (diabetesjournals.org, 2018) Type 1 diabetes mellitus is caused when the pancreas is unable to produce enough insulin, while type 2 diabetes mellitus is caused when the tissues of the body develop insulin resistance, and they fail to appropriately respond to the hormone (diabetes.co.uk, 2018). Type 1 can further be divided into immune mediated diabetes and idiopathic diabetes (diabetesjournals.org, 2018). Causes of Diabetes include the autoimmune destruction of pancreatic beta cells, resistance to insulin (diabetesjournals.org, 2018). Several factors can increase the risks to diabetes and includes: family history of the disease; ethnicity; overweight/obesity; stress; some types of medications; pancreatic injury; autoimmune dysfunction; hypertension; high blood cholesterol levels; age; smoking and alcoholism and pregnancy (clevelandclinic.org, 2018). Signs of diabetes are: increased hunger and thirst; dryness of mouth; urinating frequently; sudden loss of weight; blurring of vision; weakness; tingling and numbness in feet and hands; longer time for the healing of wounds; dryness of skin and yeast infections (clevelandclinic.org, 2018). Treatment options are: diet change; oral medications; exercise; insulin treatment; identification and treatment of concurrent diseases (Kow, 2018). Difference with diabetes insipidus: Diabetes Insipidus however is another type of diabetes that is caused due to inadequate production of Arginine Vasopressin hormone or an inability of the distal tubule/collecting ducts of the nephron to respond to it (Rossi Ross, 2018).
