Difference Between Tangled and Classic Princess Movies

Jaimie Kim English 1: Language Dynamics First Draft of Analytical Essay November 6, 2012 â€Å"Well, I’m really not supposed to speak to strangers, but we’ve met before †¦ once upon a dream. † This quote from Sleeping Beauty portrays Walt Disney Productions’ grand tradition of Disney princess movies of how most of the female protagonists are waiting for her love. . In 2010, however, Disney created a movie, named Tangled, which was based on the Grimm Brothers’ tale of Rapunzel. Although Disney decided to put its own version of this tale, Tangled is still about the long-haired princess who is locked away in a tower by a witch.Instead of dreaming about love, Tangled presents a story where Rapunzel makes a deal with a thief, Flynn Rider, to go on an escapade to see the festival of lights that appear annually on her birthday. Among the classic Disney princess movies, Tangled is distinguishable because of the lack of femininity shown in the title. Di sney had named all the fairy tales with titles that did not intrigue all audiences, such as Cinderella, Beauty and the Beast, and Sleeping Beauty. On the contrary, the tale about Rapunzel was not named Rapunzel, but rather the title Tangled, which interested a larger audience.Another difference that can be seen between Tangled and The Little Mermaid, as the ideal classic princess movie, is the female protagonists approach to love – Rapunzel to Flynn Rider and Ariel to Eric. Lastly, the other princess movies were mostly all drawn by hand and appeared to be ‘flat’ while Tangled was created with computer-generated images that made the visuals more attractive and, therefore, was added to the list of successful animated films that were produced by Disney.The titles of the classic princess movies followed a pattern: Snow White and the Seven Dwarfs was a movie about the princess Snow White, Cinderella was about Cinderella, and Sleeping Beauty was about the princess Auro ra. These titles had female characteristics that caught girls’ interest, but did not appeal to the other half of the young audience – the boys. Nevertheless, those movies were successful, but why did Disney decide to change its style for the title of the story of Rapunzel?Many believed that the title change may have had something to do with them altering the traditional  Rapunzel  story enough that it warranted a completely different title. Adam Markovitz, however, argues that â€Å"because  The Princess and the Frog  was no great shakes at the box office [in 2009] and Disney wanted to make the project seem less †¦ girlish, [the title] was changed from Rapunzel Unbraided to Tangled. † This proves that Disney thought that The Princess and the Frog place in the box office was a failure because of the title.This leads to why they named the movie Tangled, so they can attract varied demographics. It also drew the audience’s attention to the duoâ⠂¬â„¢s complicated relationship. In addition, this movie was not all about Rapunzel, because there was another protagonist besides the princess – Flynn Rider. By having the title as Tangled, Disney broke the standard of titling the princess movies by their names. Based on the main character’s attitude towards love, Tangled is distinctive from Disney’s The Little Mermaid. I specifically chose this classic princess movie because many believe that Rapunzel is an Ariel ‘knock-off. Throughout The Little Mermaid, Ariel and Eric communicate to each other by only smiling and doing gestures. It was slightly ridiculous how they still managed to fall in love, as shown in the scene where Ariel udders: â€Å"Daddy, I love [Eric]! † and, in the end, gets married. The reason behind the whole concept of love at first sight is, as Robin Murray says, â€Å"If Ariel wasn’t attractive, Eric would not be as motivated to spend time with her. Likewise, if Eric was unattractive, Ariel wouldn’t have sold her soul to be with him. (146) This proves that fact that the relationship was based entirely on looks, because these two characters did not communicate with each other effectively. As a result, they knew nothing about each other besides seeing that the significant other was attractive and, therefore, the one for them. This shows that the Disney princess movies were all about the idea of love at first sight. Aside from the concept of love, Tangled was a movie that had a plot that related to reality, minus the magical hair of Rapunzel. This can be seen at â€Å"the moment where Rapunzel scoffs at Flynn when he broke out his charm.This sets her apart from most of the other princesses, who would most likely swoon over Flynn’s charisma. In the presence of an attractive guy, Ariel jeopardizes her existence, but Rapunzel is not impressed and is ready to use her frying pan as a weapon. Throughout the movie, Rapunzel and Flynn’s relationship contrasts greatly from Ariel and Eric’s. They don’t fall in love instantly, which doesn’t follow that princess movies’ storyline of love at first sight. â€Å"Their relationship progresses and the audience are able to witness all the individual brilliant moments they shared together. Rapunzel and Flynn first had a friendship that was a combination of fun and passion that later progressed organically and realistically, into love. Rapunzel’s approach to love was more respectable and relatable to the viewers, which shows the difference between Tangled from not only The Little Mermaid, but also to the rest of the classic princess movies. The classic Disney princess movies were all made from the traditional hand-drawn process. Due to limitations in computer technology, many basic principles of animation had been absent from these movies.Tangled was created by using  computer-generated imagery, known as CGI. Even though it was a CGI film, the producers wanted this movie to be more attractive visually by still having movement that mimicked the soft fluidity of the hand-drawn art found in classic Disney princess movies. This is why Disney decided to have the movie modeled after the romantic look of French Rococo oil paintings on canvas from the artist, Jean-Honore Fragonard, as stated by New York Times. (Scott) This helped add an atmosphere that had a magical appearance.Rather than focusing on realism, the 3D team decided to use an aesthetic approach that drew the audience in a fantasy. Tangled’s stereoscopic supervisor, Robert Newman, explains of the process of the new approach: â€Å"We’re using depth more artistically than before, by using a new technique called multi-rigging, which is made up by multiple pairs of  virtual cameras. Each pair is used individually on each separate element that adds depth to a scene, like background, foreground and characters, without adjusting for the relation with t he other pairs.

Argue and Persuade Essay

I can see why some people may think that there is no benefit to be gained by analysing the poem Half-Past Two, as some may find it tedious and would rather enjoy the poem as it is. Yet, I firmly believe analysing a story/poem definitely does assist our understanding of a certain story/poem. In the poem Half-Past Two there is no doubt in my mind that without discussing the poem with others you can not understand or appreciate it fully. As with all poems there are so many concealed or secret meanings with in it, by discussing the poem these can be revealed so everyone knows the whole meaning of the poem. By understanding a poem/story you will also enjoy it more as you won’t have to try and figure out the plot of the story. After reading a poem you can then analyse it then read it again with a better understanding, therefore relish its full significance. If you were reading a story or a poem, which you do not understand it would become more of a choir to read, rather than a pleasure. By studying the poem Half-Past Two you can see the good use of puns, personification, repetition and other literary devices and begin to cherish the real effort and skill put in by the writer. You can also learn new ways that you could possibly improve your own standard of writing. You may acquire improved methods of adding literary devices into your work, you can also expand your vocabulary by reading professional poets/writers work. When analysing the poem Half-Past Two you are given a good insight on how a young boy’s world might work, when not being able to read time. You can understand his feelings when he is left alone, without a clue what to do, but only left to stare at the clock and fall in to a timeless land. You can see that by not knowing time a child my have his own regime which he sticks too, yet when put out of it would find it hard to get back into it as he may have lost track of his own time. My opinion has been obviously displayed in this essay, I think that without fully understanding a poem/story (mainly poems as they usually have the writers own personal feelings embedded into the poem they have wrote) you can not enjoy it to its full potential. I’m sure everyone has watched a film they did not understand and therefore did not enjoy it fully. Yet after watching it a second time (a form of analysis) you will understand the plot sufficiently and will prefer it on the second viewing. This is what my argument is based on, without understanding you do not have the full enjoyment from anything, be it a film, a poem or a story.

Sweden in Review - Essay Example Sweden is located in Northern Europe within the Scandinavian region. It is between Finland and Norway in the north, and borders the Baltic Sea, the Gulf of Bothnia, Kattegat and Skagerrak in the other sides. The country experiences temperate climate in the south, with notable cold, cloudy winters as well as, cool and partly cloudy summers in the northern region. The family unit is extremely significant in Sweden as it defines issues such as children rights and care. For instance, the father or mother is entitled to a leave until the newly born child reaches age of 18 months. Sweden presents a very family friendly environment in most establishments where structures such as play areas for children are observed. The parents have right of up to 60 days off to care for their children when sick, indicating the significance of the parental role. The society is observably modernized, with each family unit living independently, within the urban regions. In the interior settings, the family ob serves nuclear setting of living. The society of Sweden also observes the role of courtship and marriage which take notable grace time for the partners in the relationship. However, the concern of the female and male roles remains as males are evidently paid better and have more leverages in the social setting. The female roles of being the nurtures does not prevent them from undertaking social responsibilities. The Education Act in Sweden regulates the school system to ensure that there is secure and friendly learning environment for the students.

Clinical Research Informatics - Assignment Example Clinical research informatics primarily derives its importance from the fact that it is the lynchpin which links the innovative technologies to their use in the patient care (Majumder, 2012). Clinical research informatics facilitates the ongoing dialogues among both practitioners and researchers in their constant surge to create a dynamic environment of clinical research. â€Å"The development of CRI†¦drives a growing pool of scientific literature based on original CRI research, and high-impact tools and systems will be developed† (Richesson and Andrews, 2012). Health care organizations benefit from the clinical research informatics as they unveil innovative treatment options for the diseases to improve the quality of health care. Clinical research informatics enhance the translational continuum on four levels; â€Å"basic research to clinical trials (T1), clinical trials to academic health center practice (T2), diffusion and implementation to community practice (T3), an d ‘real world’ outcomes (T4)† (Kahn and Weng, 2012). Hence, clinical research informatics make it possible for the health care organizations to apply the theoretical knowledge to practical

QSAR Essay Example | Topics and Well Written Essays - 1500 words

QSAR - Essay Example The loaded values are expected to give descriptive information about the descriptors that will be interpreted in terms of significant biological correlation relationships. Notably, the experimental model applied in this study revealed that the main features describing the binding activities of the experimental compounds were partially charge-based receptors. This was an automatic measure of molecular electronic property. The same property can be used in an auto correlated that can be used to weigh substitute descriptors’ position. Additionally, the linear regression equation and its application can be used in predicting biological activity in the study. It is worth noting that the comparison of the result with the literature data indicates that the proposed quality of the model compared to the provided model compares well with the sophisticated 2D based method. Introduction The quantitative structured activity relationship, the QSAR techniques are currently suitable and indisp ensable in all research aspects especially in relation to biological molecular properties interpretation. Obviously, the chemical, biological, and or physical properties of a compound depend on the three dimensional (3D) molecular and atomic arrangement; however, the same properties can be examined in a two dimensional model. Notably, the capacity to produce qualitative and quantitative correlation between 2D molecular structures and their biological activities is fundamental in deciding what synthetic ways of bioactive chemicals. Numerous research works involving the application and use of QSAR have been applied in biological properties and structural determination of biological elements; for instance, the use of the Hansch molecule description. The QSARs analysis of the 2, 4- diamino – 5- (substituted benzyl) pyrimidines and 2,4 – diamino – 6 – dimethyl – 5 – phenyldihydrotriazines have suggested that neural network application have reliab le and effective results than normal or traditional application of the regression methods. In supplementation with the regression processes, other techniques of determination of the activity of the biological molecules have since been introduced. This includes the use of inductive logic programming (ILP) that has since used to model the QSAR particularly in the trimethoprim analogues binding from E. coli to DHFR. This technique applies mainly the physiochemical attributes that are usually assigned to substituent heuristically towards a general approach. This application or process is usually applied to the design problem of drugs. However, it should be noted that this method is not significantly better than the regression or the traditional QSAR method; however, it is noted to produce rules that are likely to provide insight into the stereochemistry of the biological molecules under determination. In most cases, such stereochemistry does help in determining the structure and to some extent, depending on the analysis, chemical properties of a molecule. It should be noted that more evidence are still required to assess these newly applied methods properly to ascertain the comparative trials and the analysis in numerous and different ways. The biological steroids activities usually vary considerably depending on seemingly small structural changes within or about a molecule. The fundamental molecular family usually represents very challenging characteristics for any method of prediction. This

Implementing Policy the Protects the Rights of Homosexual Students Essay

Implementing Policy the Protects the Rights of Homosexual Students - Essay Example The GSA Network has devoted significant monetary and staffing resources to addressing the problems of discrimination, harassment, and homophobia in VUSD schools through its Fresno office. The GSA Network primarily fights homophobia and intolerance in schools by empowering gay, lesbian, bisexual, transgender and heterosexual members in high schools to form and maintain local, school-based, student-run clubs called "GSAs". The GSA Network also encourages members to form community-based GSAs made up of students and supportive community members. See id. One-hundred fifty (150) GSA clubs in Northern California and the Central Valley are presently registered with the GSA Network. The GSA Network connects these school- and community-based GSAs to each other and to community resources in order to: foster safe environments for student members; educate student members and the school community about homophobia, gender identity, and sexual orientation issues; and fight intolerance, discriminatio n, harassment, and violence in schools. It is alleged that openly gay students are subject to severe verbal and physical harassment and suffer physical and emotional damage from Defendants' allegedly hostile environment. Heterosexual students are deprived of an environment that is free from hostility directed toward students who are gay or lesbian or who are perceived to be gay or lesbian. Harassment and discrimination is alleged to be a fact of life for gay or lesbian students, or those perceived as gay or lesbian, attending schools within the VUSD, including Golden West High School.. These students have been repeatedly called "faggot", "queer", and other anti-gay epithets on campus and in the classrooms, sometimes in the presence of teachers. One gay student allegedly confronted his teacher after class about students making loud, derogatory, anti-gay comments in class.. The teacher told the student that he did not hear the comments and refused to do anything about them. Gay or lesbian students, or those perceived as gay or lesbian, have been spit upon by other students on the campus of Golden West. Former Golden West students, perceived to be gay, have had food, pencils, erasers, and textbooks and other objects thrown at them. One gay student was almost hit by a car driven by another student who was actively trying to run him down. See id. One student directed a death threat to a gay student at Golden West.. Golden West students have also allegedly spray-painted the word "Fag" on a pickup truck of another student. One gay student at Golden West was attacked on campus by students yelling "fag", "queer" and other derogatory terms. When the student fought back, Golden West administrators broke up the fight and led the gay student away in handcuffs. That student did not return to Golden West. Students are allegedly afraid to associate themselves with any openly gay students on campus for fear of being verbally and physically assaulted. Students who are gay or lesbian experience chronic psychological injury from the harassment at school each day. One gay student suffers from insomnia and lies awake each night reviewing the harassment he suffered during the day and worrying about what

Industrial Salmon Farming Essay Example for Free

Industrial Salmon Farming Essay Fish farming, also known as Aquaculture, is an industry that uses sea life for commercial purposes. One of the most common fish species that are farmed worldwide is salmon. Most of the salmon Americans consume are farmed in British Columbia and grow in open net cages placed directly in the ocean; creating environmental threats in all areas it takes place. The problem with open net cages that are placed directly in the ocean is; the release of ocean harming farm waste, chemicals, and disease. Before these problems can be solved, a look at the salmon net cage industry is needed, along with the environmental impacts. Open cages are not secure in fact many farmed salmon can escape, escapees usually occur during storms or damages made to the net by their predators. According to Oceana.org â€Å"Atlantic Salmon escapes on the U.S. and Canadian west coasts are common; there were 350,000 known escapes in 1997 and farmed Atlantic Salmon have been found thousands of miles away from the closest salmon facilities.† (Farmed Fish Escapes) The problem with escapees is that they are known to travel long ways and carry diseases. Farmers are encouraged to treat farmed salmon with antibiotics sense they are in open net cages in the ocean, and are prone to diseases found in the ocean. Farmed Salmon are sterilized with antibiotics to keep other wild fish safe; the concern with the use of antibiotics in farmed salmon is that many of these antibiotics are also used to treat human diseases. Scientist Cabello works in the department of microbiology says â€Å"the industry continues to rely on these treatments, administered in net-cages open to the ocean, despite growing concerns over antibiotic resistance.†(Cabello) The antibiotics used to treat farmed salmon are becoming resistant to antibiotics making it more difficult to treat human diseases because it allows microbes to become resistant to antibiotic treatments, making it more difficult to treat human disease. (farmedanddangerous.org) Salmon farming in British Columbia can resolved by simply by separating the farmed salmon from the open net cages and into a land facility. Farming salmon on land decreases a lot of health risks, less escapees, and chemical waste. According to David Suzuki founder of The David Suzuki foundation he states â€Å"Evidence shows that land-based, closed-containment aquaculture is an environmentally, technically, and economically viable option to net-pen aquaculture.† (Suzuki) Operating a land-based facility is affordable when it comes down to all costs to the environment; it decreases environmental issues that can be a greater issue in the future. The good news is that in Canada, Washington State, and Tasmania closed containment salmon farming is being practiced (Puresalmon.org). A company that is practicing closed containment farming is AgriMarine, on the website Puresalom.org they examine and state â€Å"will yield all-year-round crops of ecologically sound salmon, raised in environmentally safe [closed] facilities — a first in an entire industry.† (qtd. In AgriMarine) Land-based salmon farms remove the risk of escaped salmon and contamination of the ocean. Open net-cage salmon farms are a se rious threat to the balance of life in the ocean and to wild salmon in particular. The solution is to grow salmon on land facilities it creates a barrier between farmed salmon and the ocean, it helps to protect the ecosystem and wild salmon from the problems caused by industrial salmon farming.

Mechanism Of Electromechanical Induction Meter Information Technology Essay

Mechanism Of Electromechanical Induction Meter Information Technology Essay As the dismal economy spawns desperate measures, most of the residents of our beloved city, Karachi are resorting to a hazardous practice which is stealing electricity. Many utilities say energy theft has risen sharply during the recent economic downturn. Culprits include residential customers whose power is turned off when they fall behind on the bills and small businesses struggling to keep their doors open. They are using a wide array of tactics. Some run wires from utility lines directly into a circuit-breaker panel to bypass the electric meter. Others attached cables on either side of a meter, swipe meters from vacant houses when theirs are removed or tamper with meters to lower their electric bills. People from KESC are finding more and more people are stealing electricity because of the poor economy, said by the sources of electricity supplying corporation. It has been investigated that 3,197 cases of theft in January and February, a 28% jump over the year-ago period. Customers have stolen power for decades, costing utilities 1% to 4% of revenue or about RS 49 billion industry wide each year, according to Electric Light Power magazine. Losses are borned by other customers. Many thieves operate home-based marijuana farms that use lots of lights and power. But the problem is basically mushrooming. Meanwhile, consulting firm Detectent has identified a double-digit arise in business thefts the past six months, many by energy-guzzling restaurants. In Landhi, Deen Baksh, 48, was charged last fall with3 meter rigging. DTE Energy says he helped about 50 downtown businesses cut their gas and electric bills by more than RS.1 million or 30% to 50% each the past several years. The practice is actually dangerous. Touching a power line may burn or even kill an untrained person. In Philadelphia this month, an illegal electricity hookup in a row house resulted in a spark a fire that killed a 30-year-old woman and her 8-year-old daughter. Utilities often learn of thefts from meter readers, neighbors or may be abnormal use patterns. They expect to detect fraud earlier as they roll out smart meters that can remotely monitor electricity usage. Electricity theft can be in the form of fraud (meter tampering), stealing (illegal connections), billing irregularities, or unpaid bills. Estimates of the extent of electricity theft in a sample of 102 countries for 1980 and 2000 are studied. The evidence shows that theft is increasing in most of the regions of the world. The financial impacts of theft has reduced income from the sale of electricity and the necessity to charge more to consumers. Electricity theft is closely related to governance indicators, with higher peaks of theft in countries without effective accountability, political instability, low government effectiveness and high levels of corruption. Electricity theft can be lowered by applying technical solutions such as tamper-proof meters, managerial methods such as inspection and monitoring, and in some cases restructuring power systems ownership and regulation. The main purpose of our report is to present solution to economic problems and then economy rate will become higher. And that loss which KESC have to bear due to this problem will be decreased. Economically this idea has great benefit both for masses and society. Once the theft of electricity would be detected then steps will be taken to stop it which will yield in discouraging the people using electricity illegally. Energy will be distributed to everyone justly thus everyone will be paying charges of only the amount they consume. Energy generating and distributing bodies will not be having extra load over their lines thus no power trips and break downs will occur so no extra money required for correcting such problems. CHAPTER NO 01 ELECTRIC METER 1.1 ELECTRIC METERS: An electric meter or energy meter is equipment that can measure the amount of electrical energy consumed by a residence, business, or an electrically powered device. Electric meters are usually calibrated in billing units; the most common is the kilowatt hour. Periodic readings of electric meters give billing cycles and energy used during a cycle. In settings when energy savings during certain periods are desired, meters may measure demand which is the maximum use of power in some interval. In some areas, the electric rates are higher during specific times of day for encouraging reduction in use. Also, in some areas meters have switches to turn off nonessential equipment. Electricity meters work by continuously measuring the instantaneous voltage (volts) and current (amperes) and then finding the product of these to give instantaneous electrical power (watts) which is afterwards integrated against time to give energy used (joules, kilowatt-hours etc.). Meters for smaller services (for instance small residential customers) can be connected directly in-line between source and customer. For larger loads, i.e. more than about 200 amps of load, current transformers are used, so that the meter can be located other than in line with the service conductors. The meters fall into two basic categories, electromechanical and electronic. 1.1.1 Mechanism of electromechanical induction meter. 1. Voltage coil many turns of fine wire encased in plastic, connected in parallel with load. 2. Current coil three turns of thick wire, connected in series with load. 3.Stator-concentrates and confines magnetic field. 4.Aluminum rotor disc. 5. Rotor brake magnets. 6. Spindle with worm gear. 7. Display dials note that the 1/10, 10 and 1000 dials rotate clockwise while the 1, 100 and 10000 dials rotate counter-clockwise. The electromechanical induction meter operates by counting the revolutions of an aluminum disc which is made to rotate at a speed proportional to the power. The number of revolutions is thus proportional to the energy usage. It consumes a small amount of power, typically around 2 watts. The metallic disc is acted upon by two coils. One coil is connected in such a way that it produces a magnetic flux in proportion to the voltage and the other produces a magnetic flux in proportion to the current. The field of the voltage coil is delayed by 90 degrees using a lag coil.[16] This produces eddy currents in the disc and the effect is such that a force is exerted on the disc in proportion to the product of the instantaneous current and voltage. A permanent magnet exerts an opposing force proportional to the speed of rotation of the disc. The equilibrium between these two opposing forces results in the disc rotating at a speed proportional to the power being used. The disc drives a register mechanism which integrates the speed of the disc over time by counting revolutions, much like the odometer in a car, in order to render a measurement of the total energy used over a period of time. The type of meter described here is basically used on a single-phase AC supply. Different phase configurations use additional voltage and current coils in them. 1.1.2 CURRENT TRANSFORMER (CT) METERING: Huge businesses or multi storey buildings use so much power that they cant be connected to the network via the usual methods so in order for these sites to be metered, the load needs to be broken down so the meter will be able to cope with it and then be multiplied out again in order to get the full amount of power being used. This is known as CT metering. Actually the load comes into a CT chamber from where it is then distributed from buzz bars containing transformers to CT links and then into the meter. The CT chamber also goes into the customers switchboard. The rating of the transformers finds out the multiplier to be applied when calculating true usage. 1.1.3 METER USED IN THE PROJECT: The meter used in our final year project is electromechanical induction meter. 1.2 UNIT OF MEASUREMENT: Kilowatt hour is the most common unit of measurement on the electricity meter which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules. Some electricity companies also use the SI mega joule instead. Remote current and voltage sensors are be read and programmed remotely by modem and locally by infra-red. The circle with two dots is the infra-red port give the reading. Tamper-evident seals are also present in some meters. Demand is usually measured in watts, but averaged over a period, most often a quarter or half hour 1.3 ELECTRICITY THEFT: Meters can be controlled to make them under-register, effectively permitting power use without paying for it. This theft or fraud can be dangerous and also dishonest. Electricity theft can be in the form of i)fraud (meter tampering) ii)stealing (illegal connections) iii)billing irregularities iv)Unpaid bills. Another common method of tampering on older meters is to attach magnets to the outside of the meter. They magnetically saturate the coils or current transformers, preventing the alternating current from forming eddy currents in the rotor, or inducing voltages in the current transformer. Also rectified DC loads cause mechanical (but not electronic) meters to under-register. DC current does not cause the coils to make eddy currents in the disk so this causes reduced rotation and a lower the bill. Some combinations of capacitive and inductive load can also interact with the coils and mass of a rotor and cause reduced or reverse motion. 1.3.1 Basic Layout Of The Project Including Electricity Theft Possibilities: Bypass wire Breaker to cut out the meter Home Neutral Wire, neutral current iN Phase wire, phase current iP Earth wire Meter Case 1: If there is no bypassing of the meter and the entire load is OFF. iN (Neutral current) = iP (Phase Current) = 0 Case 2: If there is no bypassing of the meter and the entire load is ON. iN (Neutral Current) = iP (Phase current) = some value Case 3; If there is meter bypassing and the entire load is ON. iP (Phase current ) = 0 iN (Neutral Current) = load The first target is to sense / measure phase and neutral current. And if case 3 is verified than it will be a theft case. 1.3.2 Outcomes Of Electricity Theft: The evidence shows that theft is vastly increasing in most regions of the world. The financial impacts of theft have resulted in reduced income from the sale of electricity and the necessity to charge more to consumers. Electricity theft is closely concerned to governance indicators, with higher levels of theft in countries without effective accountability, political instability, low government effectiveness and high levels of corruption. Power theft has surely become an infamously prevalent practice in many parts of the country, both rural and urban. Many cases go unreported in various cities and villages, costing a lot to our countries burdened economy. People actually pay some local electrician a little money to reverse the electricity meter of the house and/or slow its pace. Some people also learn the trick from an electrician and help their family/friends steal electricity. 1.3.3 General Methods To Reduce Electricity Theft: Electricity theft can be reduced by Applying technical solutions such as tamper-proof meters. Managerial methods such as inspection and monitoring. Restructuring power systems ownership and regulation.. A common method of tampering on older meters is to attach magnets to the outside of the meter. These magnetically saturate the coils or current transformers, preventing the alternating current from forming eddy currents in the rotor, or inducing voltages in the current transformer. Rectified DC loads cause mechanical (but not electronic) meters to under-register. DC current does not cause the coils to make eddy currents in the disk, so this causes reduced rotation and a lower bill. Some combinations of capacitive and inductive load can interact with the coils and mass of a rotor and cause reduced or reverse motion. CHAPTER NO 02 MEASUREMENT OF AC CURRENT: 2.1 DESCRIPTION: Here we have considered household power is single-phase electric power, with two or three wired contacts at each outlet. The live wire (also known as phase, hot or active contact), carries alternating current between the power grid and the household. The neutral wire completes the electrical circuit by also carrying alternating current between the power grid and the household. The neutral is staked into the ground as often as possible, and therefore has the same electrical charge as the earth. This prevents the power circuits from rising beyond earth, such as when they are struck by lighting or become otherwise charged. The earth wire or ground connects cases of equipment to earth ground as a protection against faults (Electric Shock). 2.2 MEASUREMENT OF AC CURRENT: Its very difficult to measure ac current and produce voltage proportional to it. For measurement of ac current Hall Effect devices are mostly used. They produce the voltage proportional to the magnetic field in the air gap by inserting Hall Effect magnetic field sensor in the current transformer core air gap. The circuits below measure the ac current without using Hall Effect devices. 2.2.1 WORKING: FIG 1: An electric current J2 is introduced in the secondary winding of the coil which is proportional to the primary winding J1.Th secondary current can be controller by means of number of turns on primary and secondary winding. The primary winding either have one turn or a number of turns wrapped around it while the secondary winding has usually multiple turns around it. If the current transformer is ideal then the current in the secondary winding is equal to that in primary winding. But if it is possess non-ideal characteristics then the current in both windings will not be equal due to substantial phase angle, error of ratio, and/or wave shape in its output. They are the function of: The properties possess by magnetic core. How much burden on it. How much dc component present in the primary current. FIG2: Due to burden in the secondary the currents in the secondary and primary arent equal. Fig 2is used to reduce this effect .V4 is the voltage which is proportional to the rate of magnetic flux and is introduced by terminating the sense winding 10 to high impedance; the effective burden can be reduced by applying it tin series to the secondary winding after it is being amplified. Now the currents in secondary will be proportional accurately to that in primary since the magnetic flux changes in the core is reduced to zero. Smaller flux changes and higher accuracy will be achieved by higher gains in the amplifier circuit while on the other hand this leads to instability and associated =oscillations in the circuit. This technique is a better measure of ac current but the problem raised may be due to the dc component in the primary current FIG 3: Compensation voltage is generated by using secondary current as input and this voltage is required for driving the secondary current. The voltage generated V1 is proportional to the driving current J2 and the output voltage V3 is produced as an information signal. The advantage of above circuit is that instead of using Hall Effect sensors ordinary current transformers can be utilized to measure the ac current with a dc component .The above current sensor has the following properties: Even in the presence of primary current the current transformer gives accurate output. This circuit uses a relatively inexpensive and simple magnetic core. Stable over temperature and time. Primary current in in effected by noise. The voltage V3 is utilized further to obtain a dc voltage. For this purpose this ac output is passed by a rectifier circuit in order to obtain a dc voltage at the output. CHAPTER #03: MICROCONTROLLERS 3.1 INTRODUCTION: Microcontrollers are devices that have CPU, RAM, ROM, I/O ports, and timers all on a single chip. In other words all are embedded on a single chip. For applications in which cost and space are critical issue microcontrollers are preferred for their above mentioned features. Microcontroller is one of the major components of this design as it plays key role of the coordination between all the components. It inputs current signal and evaluates the theft. The result is then sent to remote office by connecting mobile to microcontroller. AT commands are used for communication between mobile and microcontroller. Microcontrollers are available with different instruction set, registers, speed, packaging and costs. There are many different types of microcontrollers. Freescales 6811, Intel 8051, Zilogs Z8, and PIC 16X from microchip technology are popular 8 bit microcontrollers. Nowadays 16 bit and 32 bit microcontrollers are also available. Microcontrollers are not compatible with each other because each has a different instruction set and registers. Certain important points must be kept in mind while selecting a microcontroller for a particular application. Firstly it must be able to satisfy all computational needs. These computational needs include capacity and speed. Speed: While choosing a microcontroller it should be operating at the speed that is required for the application Capacity: For certain applications programs are too long and they exceed on chip RAM capacity. Therefore it is necessary to consider on chip RAM memory. Secondly it must be compatible with devices used in application. This is an important issue. There are many microcontrollers which support only a particular baud rate and are incompatible with the devices that operate at the higher baud rate. Thirdly it must be available in required quantities and at the required costs. 3.2 POPULAR MICROCONTROLLERS: Two important microcontrollers that are widely used are 8051 and PIC. 3.2.1 8051 Family: There are many members of 8051 family which are produced by different vendors and have different features. Some of the well known are: 8051: 8051 was originally produced by Intel corporation .It has 4Kbytes ROM and 128bytes on chip RAM .Other products are 8052 and 8031 microcontrollers. These two have additional features such as increased ROM capacity, speed and timers. AT89C51:One of the most widely used 8051 microcontrollers is AT89C51 from Atmel Corporation. It is one of the most widely used from 8051 microcontrollers because of its easy availability and low cost. OTP version of 8051: One time programmable versions of 8051 are also widely used. Because of its low cost it is used for mass production. 3.3 PREVIOUS APPROACH: Earlier for project purpose Atmel89C51 was selected and ADC0808 was used along with it to convert current to digital. 3.3.1 ATMEL 89C51: It is one of the most commonly used controllers. The reasons behind its popularity are: It is widely available. Programming language is very simple. All its development tools are readily available. 3.3.1.1 Features: It is low powered and 8 bit microcontroller. 32 I/O lines. 6 interrupts 2 timers. 4K flash memory Serial programming is also possible. The figure below shows the pins of Atmel AT89C51. If AT89C51 is used for the current implementation then following points need to be considered: 3.3.1.2 Interfacing ADC With Microcontrollers: It does not have built in ADC therefore an external ADC is interfaced to entertain analog inputs. Normally ADC0808 and ADC0848 are used. 3.3.1.3 Serial communication: For serial communication it has built in UART mode. There is a special serial register known as SBUF. 3.3.1.4 ADC0808: As current is analog quantity and 8051 can only accept digital inputs therefore an ADC was needed .For this purpose ADC0808 was preferred as it is easily available in markets and compatible with 8051. Due to the compatibility issue atmel8951 was replaced by pic16F877A. 3.3.2 PIC: PIC stands for programmable Interface controller and it is made by microchip technology. PIC is widely preferred for industrial applications due to their low cost, capacity, extensive features and wide availability of development tools like its programmer, compiler etc. 3.3.2.1Features Of PIC: It follows Harvard architecture that is code and data spaces are separate. They even have a separate bus. This allows program and data to be fetched simultaneously. Code space is implemented as ROM whereas for data space we have general purpose RAM. However addressable data space is small. There is only one accumulator. Most of the PIC controllers are 8-bit microcontroller that all data should be in 8 bits and all operations are also performed in 8 bits chunks. They also support instructions, operations and commands that allow user to work on single bit. It has predefined instruction set with few changes for different versions .The instruction set includes instructions that support direct memory addressing as well as indirect addressing. It also supports conditions and branching. Newer versions of pic also have built in ADC into the microcontroller. PIC have hardware call stack which cannot be accessed through software. They save return addresses. TYPES OF PIC MICROCONTROLLERS: There are many PIC series of which well known are as follows: PIC17 SERIES PIC18 SERIES PIC32 SERIES PIC24 SERIES PIC16 SERIES For the project PIC16f877A is covered in detail therefore PIC 16 series is discussed briefly. 3.3.2.2 PIC16 Series: PIC16 Series are small, fast, and are available in most of areas. There are many different variants of pic16 series in which some have more I/O pins some have ADC, some have more memory. 3.4 CURRENT APPROACH: 3.4.1 PIC16F877A: For this project pic 16f877A has been used .The reasons behind using it were as follows: It is widely available in most of the areas. It has built in 10 bit ADC that was needed for our project. Its compiler and programmer were also easily available. It supports baud rate required for our application and it is compatible with devices that are used. It is relatively easy to program. The details of the pins are provided in the Appendix A 3.4.1.1 Features Of PIC16F877A: It is a 40 pin device 5 I/O ports A, B, C, D and E some pins are multiplexed so that they can be used for peripheral functions. 15 interrupts 8 A/D input channels 35 single word instructions and 1 instruction is composed of 14 bits. 20 MHz operating speed Data memory of 368 bytes EEPROM memory of 256 bytes 3 timers 2 analog comparators. 3.5 HARDWARE SECTION: Hardware design of PIC consists of combining different modules and devices with the controller that work together in order to attain information from the E-meter and read into the micro-controller. In this section ports, oscillators, registers of PIC that are used for implementing the design are briefly discussed: 3.5.1 Oscillator: External oscillator with a frequency of 12 MHz is used in order to achieve clock speed of 8MHz.The baud rate is set at 9600kbps. Internal oscillator of pic is not used. 3.5.2 I/O Ports: As the current has to be sensed through the microcontroller therefore portA is used and is configured for analog input (AN0 to AN7). Its corresponding direction register is TRISA. 3.5.3 Analog to Digital Converter Module: PIC16F877A has eight pins for Analog-to-Digital (A/D) Converter module. The conversion of an analog input signal results in a corresponding 10-bit digital number. It can even operate in sleep mode. The A/D clock must be derived from the A/Ds internal RC oscillator. The AD module has four registers adresh, adresl, adcon0 and adcon1. The 10 bit AD result is stored in adresh and adresl registers.ADCON1 is used for configuration of port pins. The operation of AD module is controlled through ADCON0. 3.5.4 USART: In order to generate alarm at remote office, controller is connected to mobile. The phone is connected to Universal Synchronous Asynchronous Receiver Transmitter (USART) module which is one of the two serial I/O modules of PIC16F877A. USART is also known as a Serial Communications Interface or SCI. USART uses standard Non-Return to- Zero (NRZ) format (one Start bit, eight or nine data bits and one Stop bit). The USART transmits and receives the LSB first. The transmitter and receiver function independently. 3.6 SOFTWARE DESIGN: 3.6.1 Development Tools: The code is written in pic basic pro language. The code is then converted to hex via microcode studio and hex code is loaded into pic16F877A through quad programmer. Microcode studio is used because its free version is easy available on internet. For compiler three header files are made. One file is used by compiler other is used by programmer. The file with the extension .BAS is used by pbp .Pbp then makes .ASM file from it. It then makes .ASM file from it. If code is error free then assembler required output file with hex code in it. This hex code is loaded in the pic by quad programmer. 3.6.2 Program Code: There are multiple parts of the software design, as the micro-controller plays many parts in the coordination of the instrumentation panel. Firstly internal ADC of the PIC16F877A is configured to sense the current. The next step for the code is to check if input is greater than 0 .If it is greater than 0 then a message is sent to remote office through mobile. For this AT commands are used that are specially made for communication between GSM modules and microcontroller. Other than the mentioned AT commands in the following table are in appendix B COMMANDS PURPOSE ATZ AT+CMGF 3. AT+CMGS 4. AT+CMGL Recall Stored Profile Message Format Send Message List Messages CHAPTER NO 04: WIRELESS ACCESS TECHNOLOGIES: 4.1 EVOLVING WIRELESS TECHNOLOGIES IN PAKISTAN: There are two important wireless access technologies that can be used within Pakistan and are feasible for our project and that are: WIMAX GSM 4.2 GSM TECHNOLOGY: For mobile telephony systems in the world, the most popular standard is GSM. The GSM Association estimated that 80% of the global mobile market uses the standard. 1.5 billion People across more than 212 countries and territories uses GSM technology for their benefits. This means that subscribers can use their phones throughout the world between mobile network operators, enabled by international roaming arrangements. GSM is considered a second generation (2G) mobile phone system because GSM differs from its predecessor technologies in that both signaling and speech channels are digital. GSM also facilitates the wide-spread implementation of data communication applications into the system. The GSM standard provides an advantage to both consumers, who may benefit from the ability to roam and switch carriers without replacing phones, and also to network operators, who can choose equipment from many GSM equipment vendors.GSM also pioneered cheapest implementation of the short message service (SMS), also called text messaging, which has since been supported on other mobile phone standards as well. A worldwide emergency telephone number feature is also provided by this standard. GSM also supports indoor coverage and may be achieved by using an indoor picocell base station, or an indoor repeater with distributed indoor antennas fed through power splitters, to deliver the radio signals from an antenna outdoors to the separate indoor distributed antenna system. When a lot of call capacity is needed indoors then these are typically deployed; for example, in airports or shopping centers. However, this is not a prerequisite, since indoor coverage is also achieved by in-building penetration of the radio signals from any nearby cell. The modulation technique used in GSM is Gaussian minimum-shift keying (GMSK). It is a kind of continuous-phase frequency shift keying. In Gaussian minimum-shift keying, the signal to be modulated onto the carrier is first smoothed with a Gaussian low-pass filter prior to being fed to a frequency modulator, so it greatly reduces the interference to neighboring channels (adjacent-channel interference). 4.2.1 GSM CARRIER FREQUENCY: GSM networks operate in a number of different carrier frequency ranges (separated into GSM frequency ranges for 2G and UMTS frequency bands for 3G), the most 2G GSM networks operating in the 900Â  MHz or 1800Â  MHz bands. The 850Â  MHz and 1900Â  MHz bands were used instead, Where these bands were already allocated (for example in Canada and the United States). In some countries the 400 and 450Â  MHz frequency bands are assigned In rare cases because they were previously used for first-generation systems. In Europe Most 3G networks operate in the 2100Â  MHz frequency band. Regardless of the frequency selected by an operator, it is divided into timeslots for individual phones to use. That is why it allows eight full-rate or sixteen half-rate speech channels per radio frequency. These eight radio timeslots (or eight burst periods) are further grouped into a TDMA frame. In the same timeslot half rate channels use alternate frames. The channel data rate for all 8 channels is 270.833Â  kbit/s, and the frame duration is 4.615Â  ms. The transmission power limited in a handset to a maximum of 2 watts in GSM850/900 and 1 watt in GSM1800/1900. 4.2.2 NETWORK STRUCTURE: The network is structured into a number of discrete sections: The Base Station Subsystem (the base stations and their controllers). The Network and Switching Subsystem (the part of the network most similar to a fixed network). This is also called the core network. The GPRS Core Network (the optional part which allows packet based Internet connections). For maintenance of the network, the Operations support system (OSS). 4.2.3 SMS MODES IN GSM: We have two types of SMS modes in GSM SMS Text Mode SMS PDU Mode The text mode (It is unavailable on some phones) is simply an encoding of the bit stream. It is represented by the PDU mode. There are several encoding alternatives when displaying an SMS message and Alphabets may differ. The most common options are PCCP437, PCDN, 8859-1, IRA and GSM. These are

Dental Prosthetic Options

Dental Prosthetic Options S.N.: Introduction: Prosthetic options to replace a missing tooth fall into two main categories: Fixed prostheses and removable prostheses. When choosing the suitable treatment option to replace a missing upper incisor, multiple variables involving the patient wishes, expectations, dentist skills and training, cost of treatment, and clinical findings should be taken into consideration (Al-Quran et al., 2011). These factors will have a strong influence on the short and long terms success of the treatment selected. Based on the conservation of neighbouring teeth and annual failure rates, dental implants are the treatment of choice to replace a missing central maxillary incisor, followed by conventional bridges, and removal partial dentures (Pjetursson Lang, 2008). Facial growth in relation to age: Craniofacial development is a continuous process that starts intra-uterine and has shown different rates between males and females (Brahim, 2005) . Skeletal maturation in males is reported to be reached at the age of 20, while females reach the maturation phase earlier, at the age of 17-18 years (Heij et al., 2006). Therefore, it has been recommended, when selecting the prosthetic option to replace a missing tooth, to take the patient’s age into consideration. Dental Implants should be avoided until the cessation of jaw development mentioned earlier (Daftary et al., 2013) or after the end of the growth spurt (Heij et al., 2006). If dental implants are used before the vertical maturation is reached, it will not grow vertically with the alveolar bone and will be submerged at different levels depending at the patient’s age when the implants were inserted (Brahim, 2005). Dental trauma and the surrounding tissues: In most scenarios, it is rare that a single incisor will be traumatized with no damage on adjacent incisors, surrounding bone, or soft tissues. If any damage sustained to neighbouring teeth, the status and prognosis of these teeth should be assessed, as it will have a strong impact on the selection of the definitive treatment option. Traumatic avulsion of teeth, account for 0.5% 3% of all dentoalveolar trauma, and it is associated with damage to the alveolar bone, specially the buccal plate (Andreasen, 1970). After tooth extraction, reduction of the alveolar bone height and width can be as high as 50% in the first year (Schropp L, 2004) with the highest amount of bone loss within the first three months (Pietrokovski Massler, 1967). Bone loss is not even between the buccal and palatal bone plates, with more bone loss in the buccal plate (Pietrokovski Massler, 1967) and bone width than height (Van Der Weijden et al., 2009). There are several treatment options that could be used for replacing a lost maxillary central incisor: Removable Partial Denture (RPD): RPD have the advantages of minimal clinical skills required, minimal chair time, and preservation of neighbouring teeth. On the other hand, the patient satisfaction is low, with a sense of insecurity, high risk of accidental breakage, and loss. Still, RPD is the quickest, cheapest replacement option of a missing incisor, and usually used as a temporary treatment until healing is complete and bone remodelling is minimal. Resin Retained Fixed Bridges (RRB): Resin retained bridges share the advantage of removable dentures of having minimal effect on abutment teeth with no risk of pulpal injury and the reversible nature of the prostheses. It is also relatively of low cost and acceptable aesthetic result (metal frame could be masked by opaque cement on expense of translucency). The commonest failure associated with RRB is frequent debonding of 20% over 5 years (Pjetursson et al., 2008) which could cause social embarrassment to the patient. The patient could also be given an Essex Type retainer with a single tooth in the gap as an emergency prosthesis until recementation of the resin retained bridge is done. RRB could be used as a final prosthetic option but more often is used as an interim measure as it could be reversed at any time, with 87.7% 5 years prognosis (Pjetursson et al., 2008) If the prosthesis is planned to be a temporary option, Rochette type wings are made with holes to facilitate frequent removal. Conventional Bridge: This is an irreversible treatment, replacing the missing tooth with a 2 or 3 units’ conventional bridge. These offer superior retention and aesthetics over RRB by the mean of full coverage of the abutment teeth. The main drawback is the need to reduce the sound tooth structure of the abutments with 20% risk of nerve damage and higher caries risk. The reduction of tooth structure is more for porcelain fused to metal or full ceramic/Zirconia crowns than full crown which is a requirement in the anterior aesthetic zone. According to previous studies, â€Å"if the adjacent teeth are severed, or in need of being crowned, the conventional bridge is to be preferred (Annual failure rate: 1.14%)† (Pjetursson Lang, 2008). The success rate is reported to be 90 % for 10 years and 72% for 15 years (Pjetursson et al., 2008) and (Burke Lucarotti, 2012). Endosseous dental implants: When considering the success rate, dental implants are reported to have the highest documented survival rate of 94% for 5 years (Attard Zarb, 2003) and 89% over 15 years (Pjetursson et al., 2008). Dental Implants have numerous advantages over the previously mentioned treatment options. Comparing dental implants to other fixed treatment modalities, there is no danger of pulpable damage of adjacent teeth, as no abutment teeth preparation is involved. Implants also facilitate the patient’s daily oral hygiene routines around the prosthesis, since there are no connectors between the prostheses and abutment teeth, making flossing possible. Furthermore, the maintenance and regular follow ups by the dentist is easier for dental implants. Removing a conventional bridge is a challenging task compared to screw retained implant supported crowns which could be removed and re-inserted multiple times when required (not applicable to cemented crowns). For implant supported restorations in the anterior maxillary region, a detailed patient assessment, implant site assessment, and proper treatment planning is the key for a successful restoration. The planning should be derived from the restorative point of view not guided by the availability of bone. The following points should be carefully assessed: Lip position at rest and smile: The patient’s aesthetic expectations should be coupled with the upper lip position at rest and when smiling. In most cases, 2 mm of the incisal edge of the central incisors should show at rest, and it could be either 100% of all the incisors (high smile line), more than 75% visible (medium smile line), or (low smile line) showing less than 75% of the incisors. With low smile line lip position, the aesthetic challenges are lower, and the emphasis on soft tissue contouring and papilla regeneration is also lower (Tjan et al., 1984). If the patient’s expectations are high while having high smile line, patient education should take place prior to implant treatment as the implant treatment could be deemed a failure if did not meet the patient’s aesthetic requirements despite been successful in every other aspect. Attached gingiva and surrounding soft tissue: The attached gingiva could have thick, moderate, or thin architecture. Thick gingiva is more common than the thin biotype; it appears as a more stippled, flat fibrous band of attached mucosa, masking the underlying bony contours. It is associated with higher resistance to recession, better soft tissue contouring, and resistance to peri-implant disease. On the other hand, thin gingival biotypes are found in 15% of population (Tjan et al., 1984) and it is a thinner mucosal layer with the bony scalloping showing through it. This type is more prone to exposure of the implant and compromising the aesthetic result (Tjan et al., 1984). The thin biotype has been associated with long triangular teeth and more incisally positioned contact points, while the thick biotype is associated with shorter, square crowns with more apically positioned contact points (hence, more papillary regeneration). Implant size used: Implant size has a direct effect on the emergence profile of the coronal restoration and aesthetics. Natural existing teeth and available bone are helping factors when selecting the right implant diameter, while implant length should provide a safety distance to the surrounding anatomical structures. The implant diameter should allow 1.5 mm between implant and neighbouring teeth (and 3mm between adjacent implant fixtures) (Jivraj Chee, 2006). The gingival biotype also should not be overlooked when selecting the fixture diameter, for example; if wider implants are used with thin gingival biotype, the risk of recession is higher (Rodriguez Rosenstiel, 2012). Implant position: For the most aesthetic emergence profile, implants should be placed 1.5 mm – 2 mm from the adjacent tooth, 3mm – 4mm apical to CEJ (Jivraj Chee, 2006), and ideally should be placed under the proposed cingulum of the coronal restoration. A diagnostic wax up and a prefabricated surgical stent are of very important in deciding the crown and implant positions, and evaluating the amount of bony defect and the need for bone graft. Transfaring the surgical stent into the patient’s mouth will allow the visualization of the amount of incisor show and smile lines. The implant position and angulation will dictate the abutment type and the retention method used for the restoration (screw or cement retained). Available bone quality and quantity: Bone density has been classified by Lekholm and Zarb (1985) into 4 categories: Homogenous compact bone, Thick cortical bone around dense trabecular bone, Dense trabecular bone covered by thin cortical bone, Very thin cortex enclosing minimal density trabeculae. Types 3 and 4 are associated with more failure rates, and are more found in the maxilla. Therefore, under -preparation of the osteotomy site could be done to gain higher initial stability. Branemark et al 1977 defined ossteointegeration as â€Å"direct structural and functional connection between living bone and load carrying implant†. Implant fixture should be in direct contact with healthy bone in three dimensions. Therefore, the amount of available bone required around any dental implant is 1.5 mm buccally and palatally, 3 mm between adjacent implants and at least 1.5mm -2mm between implants and adjacent teeth (Misch, 2008) and (Rodriguez Rosenstiel, 2012). If buccal bone width is not sufficient, a smaller diameter implant that will be functionally and aesthetically sound could be selected. It will also allow slight palatal positioning (Rodriguez Rosenstiel, 2012). Bone grafting/augmentation procedure could be done to add the bone thickness (Esposito et al., 2009) and bone could be sourced from: Patient’s own bone (Autogenous graft): commonly could be harvested from calvarian bone, iliac crest, mandibular ramus or chin. This provides highest reported success rates (Esposito et al., 2009). Different human bone (Allograft): usually from cadaveric bone. Bone undergoes special treatment to be deproteinized and freezed (Esposito et al., 2009). Animal sources (Xenograft) usually cows or pigs. Synthetic materials (Alloplast): artificial graft material which could be used solely or in conjunction with autogenous grafts (Esposito et al., 2009). Bone regeneration membranes: these are used to act as a barrier between the superficial soft tissue and the grafted bone or material to prevent ingrowth of the fibrous tissue and allow pure bone development. These membranes could be either natural or synthetic, resorbable or non- resporbable. If block bone graft is used, it should be allowed to heal for minimum 3 months before implant placement, while bone augmentation with alloplastic materials and membranes could be done simultaneously (Esposito et al., 2009). It is worth mentioning that porcine- derived bone and membranes may not be acceptable by some patients based on their religious beliefs and a specific consent should be obtained. The bone height will also impact the papilla formation, together with the crown shape and level of contact points; the papilla regeneration is favourable is square crown, broad apical contact points, and when the distance is around 4-5 mm between bone crest and contact points (Rodriguez Rosenstiel, 2012) and (Tarnow et al., 2003). Vertical bone augmentation has been shown to be unpredictable (Esposito et al., 2009) and the patient should be aware of the black triangles (lack of papilla) if vertical bone is deficient (Tarnow et al., 2003). Conclusion: Based on the previously discussed factors and the evidence available, dental implant would be the treatment of choice if the neighbouring teeth are of good prognosis and the aesthetic results are realistic. It is safe to place an implant in 20 years old male, as the growth of the jaws is complete. A diagnostic wax up and stent could be made to evaluate the aesthetics, and available bone. A 4.5 mm buccal width is not enough to place a suitable size implant in a suitable bony envelope, so a block done graft for will be needed before the implant placement. If the source of the trauma was sports related and likely to occur again, a mouth guard should be worn to protect the implant and teeth during activity. Bibliography Abt, E.C.A.B.W.H.V., 2012.

Media Affects on the Self- image of Women Essay -- Marketing Advertisi

Media Affects on the Self- image of Women When you first glance at this article, you might say to yourself â€Å"I know what women in the media is about, it's stereotypes and sexism.† What you probably don’t know is that however subtle, these visual cues are affecting women individually and collectively, in how they view themselves and other women. Relationships are a fundamental aspect of women’s behaviorism and advertising exploits this. It turns people into objects and offers products as a replacement for human contact, producing serious affects on the self- image of women and adolescent girls. Young women aged 15 to 30 are a prime industry target since 80 per cent of all consumer products are purchased by women in this age group. Advertisers spend large amounts of money on psychological research and focus groups, and what have they learned?

Through advertising, these young women are encouraged to portray themselves as sweet and passive, but sexy and attractive. They are taught to be quiet and kind, but to compete with other girls for attention from boys. They hav... ... supposed to be competing with other girls for attention from boys. Of course we don’t take all ads literally, but we have to remember that they add up and we are exposed to up to 1500 ads daily. The cultural messages that we are receiving from these ads do affect young women immensely. To be aware of this issue is important to everyone. As author and lecturer Jean Kilbourne says â€Å"These days, self-improvement seems to have more to do with calories than with character, with abdomens than with absolutes, with nail polish than with ethics.† References Calvine, Howard.
