Cell Phones And Its Impact On Society - 892 Words

In today’s society, smartphones dominate as one of the top accessories, but there might be a problem lurking beneath that shiny exterior. Cell phones have made a dramatic advancement from the bricks with antennas to the sleek touch screen that seems to occupy the hands of every teen and working adult. These smartphones act as a status symbol for what’s in style as well as who’s on top of the social pyramid regarding the large variety of social media that can be accessed through such a small device. The younger generations might argue that cell phones are absolutely necessary in today’s society, yet youths display behaviors that create a block between their person and the rest of the people around them. While smartphones are a popular accessory, there are issues of overuse that can lead to detrimental behaviors regarding face-to-face communication and healthy behavior. Cell phones have advanced in leaps and bounds becoming one of today’s biggest industries. According to Tim Brookes Dr. Martin Cooper worked at Motorola as a researcher and executive member and made the first phone call from a cell phone on April 3, 1973. From there the cell phone only continued to advance. There has been the 1G network made for just phone calls to the 2G network with faster service and cool, downloadable ringtones.

The first reported application of commercial fertilizer through a sprinkler irrigation system was in 1958.Today, we routinely inject fertilizer solutions and suspensions into irrigation systems via calibrated injection pumps that insure precision over both space and time. We will write a custom essay sample on Efficient Use of Fertilizers or any similar topic only for you Order Now Fertigation has increased dramatically in the past 15 years, particularly for sprinkler and drip systems. For drip systems, the expansion is mostly in horticultural and high value crops. In agricultural areas with declining water supplies, drip systems have also increased. With increased irrigation, a corresponding increase in fertigation has taken place. It will continue to grow since such Figure 10. Overhead sprinkler irrigation system. systems result in less water usage and better uniformity and lend themselves to the technique much more readily than the less water-efficient and non-uniform furrow and flood systems being replaced. Effective fertigation requires knowledge of certain plant characteristics such as optimum daily nutrient consumption rate and root distribution in the soil. Nutrient characteristics such as solubility and mobility are important and irrigation water quality factors such as pH, mineral content, salinity and nutrient solubility must be considered.The need for irrigation is the main factor in fertigation because the irrigation system is primarily installed to provide water. The opportunity to fertigate is an added benefit. This chapter will address issues that must be considered to achieve maximum benefits when fertigating. 1 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars Figure 10. 2 Growers often plant vegetables under plastic mulch and fertigate using drip/trickle irrigation. Soil Chemistry Cropping and fertilization history as well as basic soil chemical properties also need to be considered prior to fertigation.Soil testing by the method recommended in a specific area is the best way to assess current fertility needs. Particular attention should be given to soil pH and its adjustment to an appropriate range for the crop to be grown. Proper pH can have a great effect on the availability of residual nutrients in soil as well as those added via fertigation. Any required soil pH adjustments should be made using conventional incorporation techniques. Fertigation is not utilized to alter soil pH’s.Cation exchange capacity (discussed in The Soil Defined) is an important consideration in determining the quantity of cations that will be retained during fertigation. In order to maintain an acceptable concentration of cations in solution, a soil with a low CEC must have its cations replaced via fertigation more often than one with a relatively high CEC, which can hold a greater quantity of ions. Since nutrients are easily added with fertigation, it is most practical on sandy, droughty soils with low CEC. These soils need frequent irrigation and nutrient replenishment.Previous chapters in this book have explained soil movement of nutrient elements when applied by conventional fertilization methods. Since fertigation does not negate classical soil chemistry, fertigated nutrients behave similarly to conventionally applied soluble nutrients followed by rainfall or irrigation. A reminder – only small quantities of nutrients applied by an overhead sprinkler system are absorbed by the foliage. There is some concern that since nitrate nitrogen (NO3-N) is highly mobile, it may leach past the root system and reach groundwater.However, leaching of NO3-N in the sands 2 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars of the Southern Coastal Plain has been evaluated. Georgia researchers compared conventional sidedress for corn with fertigation split 6 to 9 times during the growing season. Soil NO3-N with depth was evaluated in late July (near maturity). Soil NO3-N for the fertigated treatments was greater in the surface and to depths of 2 inches than for the conventional treatment. At a depth of 2 feet, greater concentrations of NO3-N were found for the conventional application.Data such as these support the application of smaller amounts of N more frequently in order to expose lesser quantities to the possibility of leaching. In contrast to nitrate N, phosphorus (P) fertilizer moves very little in the soil. When broadcast on the soil surface, it will not normally move more than l to 2 inches below the soil surface. Therefore, fertigation of P is highly inefficient when using sprinkler or flood irrigation techniques. However, P fertilizer applied in drip systems may be rather efficient. An advantage of drip irrigation is that plant nutrients can be applied directly in the root zone.Since the majority of roots in drip-irrigated crops are located within the wetting zone, drip applied P will be placed in the soil region containing the highest root density. Therefore, the P applied in this manner is generally used more efficiently by plants than if the same amount of P were surface applied. Water Quality Considerations For successful fertigation, careful attention must be given to water quality. The quality of water required depends on several factors, but foremost is the type of fertigation. Drip fertigation requires the highest quality water, i. . , free of suspended solids and microorganisms that plug small orifices in emitters. Only solutions should be used for drip/trickle fertigation. As the orifice size increases, e. g. on sprinkler systems, suspensions can be tolerated. Precipitation of fertilizers within the irrigation systems can be a very serious problem if solubilities are exceeded. One such problem commonly encountered is with calcium concentrations exceeding about 100 ppm. As calcium concentration increases and phosphates are injected, the probability of precipitation increases.When the water contains very high levels of calcium and magnesium, an injection of ammonium phosphates will result in precipitates deposited on pipe walls as well as in orifices and sprinklers. Often this will completely plug the irrigation system. If appreciable salts are in the water used for fertigation, one needs to consider the total amount of salts applied to the crop between leaching rains rather than only the amount applied in a single fertigation. You read "Efficient Use of Fertilizers" in category "Papers" Crops vary widely in their tolerance to salts; therefore, the number of irrigations as well as the salt concentration must be considered. In some areas, high levels of boron (B) in irrigation water is a problem. Some sensitive crops can tolerate only about 1 ppm B. Total irrigation with water containing l ppm B applied to sensitive crops on light textured soils should not exceed 3 acre-inches between leaching rains. 3 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars Fertilizers For Injection Into Irrigation Three qualities are necessary for a good source of fertilizer for fertigation: (1) it must contain the needed nutrient elements in a form available to plants or in a form that is readily converted (i. e. urea is readily converted to available NH4- and NO3-N forms in good soil conditions); (2) it must be uniformly distributed–either uniformly broadcast for sprinkler, furrow, or flood or uniformly distributed among emitters for drip/trickle; and (3) the chemistry of the application must be such that plants are not burned or stunted and irrigation lines, emitters, or orifices are not restricted or plugged. Considering these limitations, a rather long list of nutrient sources can still be used. In order to provide for the latter two limitations listed, the materials must either be in solution or be in suspension.For drip systems, solution is always needed and only clear liquid should be used. Nitrogen is the most fertigated element due to high plant nutritional needs, to its great mobility in soil following chemical and biological transformation to NO3-N, and because of the many soluble sources of N fertilizers available for fertigation. Many forms of N have been used in fertigation. Urea and UAN solutions are probably most commonly used, but most any soluble form of dry fertilizer can be used. Anhydrous ammonia or any other N fertilizer that has free ammonia should not be applied through sprinkler systems. Phosphoric acid, and ammonium phosphate solutions can be used as sources of phosphorus in drip systems. Ammonium phosphate solutions are subject to precipitation if injected into water with high calcium and/or magnesium concentrations. Potassium fertigation is usually accomplished with potassium chloride (muriate of potash) due to its solubility and relative low cost per pound of K. For most crops, foliage burns are not a problem due to the great dilutions in irrigation systems. Relatively pure grades of potassium chloride (white, 62% K 2O equivalent) are normally used in fertigation.Potassium nitrate has been used as a source of K and N, and potassium sulfate as a source of K and S. These K sources are less soluble and cost more per pound of K than potassium chloride. Sulfur, when needed, can also be provided as ammonium thiosulfate, ammonium sulfate or flowable S. It can be readily mixed with UAN and several other soluble fertilizer grades and injected. Magnesium sulfate (Epson salts) is often used to supply Mg and S. Micronutrients such as iron, zinc, copper, and manganese may (if applied in forms such as sulfates or chlorides) react with salts in the irrigation water and cause precipitation and clogging.However, many of the micronutrients can be applied as chelates – such as iron or zinc EDTA. Chelates are generally highly water soluble and consequently, will cause little clogging or precipitation. 4 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars Use Fertigation Properly And According To Regulations Fertilizer nutrients have the potential of getting into the irrigation water source if proper operating procedures and safety devices are not installed or maintained by the operator. Some states require a permit for fertigation. Be sure you are in compliance with your local regulations.Reputable fertilizer and chemical dealers should be able to provide the type of equipment shown in Figure 10. 3. Figure 10. 3 Safety devices and arrangements for fertigation through an engine powered irrigation system. Figure 10. 3 shows a recommended layout for direct injection of nutrients into irrigation pipelines. The following components are part of the system: 1. Backflow prevention device (check valve) in water line upstream of fertilizer injection – this prevents reverse flows from the irrigation system down a well or other water source. 2. Vacuum relief valve – prevents a vacuum from forming upstream of the check valve. . Backflow prevention device (automatic, quick-closing check valve) in fertilizer feed line – prevents reverse flows of water or fertilizer into the fertilizer storage tank. 4. Normally closed, solenoid-operated valve – located on the intake side of the injection pump to prevent fertilizer flow during irrigation system shutdown. 5. Electrical interlock for injection systems using electric-driven fertilizer pumps this ensures that the injection pump will shut down if the irrigation pump does. 5 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars 6. Low pressure drain valve – to drain water from the pipe between the check valve and the water source, including any leakage past the check valve. Irrigation Scheduling And Fertigation Successful moisture management calls for applying the right amount of water at the proper time. The amount of water needed will depend principally on the water-holding capacity of the soil, the soil profile depth, and the crop to be grown. Research has shown that applying N solutions through sprinkler systems on sandy soils gives greater efficiency than from preplant broadcast and sidedress applications (Table 10. ). This also allows the N to be applied at the time the crop needs it. The data in Tables 10. 2 and 10. 3 illustrate the nutrient uptake of N and K for corn and cotton. Fertilizer applications can be timed with the irrigation to supply nutrients at the most optimum growth stage. Table 10. 1: Effect of Multiple Fertilizer Applications on Irrigated Corn Fertilizer Schedule Preplant and two sidedress Bi-weekly starting at emergence Time of Last Application* 8 12 No. of Applications 3 7 Relative Yield % 72 100 * Weeks after emergence (Source: F.

This technique generally utilizes conventional application of N at planting and the remainder via fertigation. This method improves N uptake early in the season when root systems are small and require high N. Later in the season, this sequence of applications anticipates N requirements while minimizing the risks of nitrate leaching. Fertigation is also sometimes used to apply supplemental applications of potash, sulfur and certain micronutrients. The need to apply such nutrients should be determined by plant analysis.Frequency and timing of water application have a major impact on yields and operating costs. For the most efficient use of water it is desirable to frequently determine the soil moisture conditions throughout the root zone of the crop being grown. Two proven practical field methods for measuring soil moisture are tensiometers and electrical resistance meters. Moisture measuring instruments should be installed at three to five locations in the field. The installation site should be representative of the soil types in the field and should be located so that it is convenient to read them on a daily basis.Figure 10. 3 illustrates the installation of tensiometers. Since the tensiometers measure the soil water levels, they must be placed in a manner that accurately reflects what conditions the root system is encountering. One should be placed six inches deep and the other 12 inches deep. The six inch depth tensiometer is used to evaluate when to start irrigating while the twelve inch depth tensiometer is used to evaluate water penetration into the soil profile plus over-or-under watering. 7 Efficient Fertilizer Use — Fertigation: by Dr. Bill SegarsFigure 10. 5 Installation of tensiometers in a corn field. A tensiometer (Figure 10. 5) reading of less than 20 centibars indicates that the amount of available moisture in the plow layer is favorable. As the readings become higher, the amount of available water decreases, indicating drier conditions and a need to start irrigating. The response of corn to three selected refill points (readings on the tensiometer) on a loamy fine sand is shown in Table 10. 4. The highest yields occurred by irrigating corn when the tensiometer reached 20 centibars. Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars Figure 10. 5 Diagram of a tensiometer. 9 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars Table 10. 4: Grain Yields of Irrigated Corn at Three Selected Soil/Water Refill Levels Total Irrigation Number of Water Applied Irrigations (IN) 11 8. 7 6 7. 1 4 -4. 7 — Tensiometer Reading When Irrigated 20 40 60 — YieldBu/A 190 175 160 115 Source: The University of Georgia Coastal Plain Experiment Station The type and size of the irrigation system will also influence scheduling.Center pivot systems that make complete 3600 circles require different schedules than center pivot systems that do not make complete circles. Cable tow systems require altogether different scheduling. Consult with your irrigation equipment supplier to determine the most efficient schedule for a particular system and field situation. Other Important Factors To Consider When Fertigating 1. Distribution uniformity of the irrigation water is critical for uniform application of the fertilizer. 2. Surface irrigation systems generally produce surface runoff.Make sure that any surface runoff during fertigation is picked up and reused on the field being treated or a similar field that is also being treated. Fertigation may not be suitable on fields that are very susceptible to runoff (i. e. steep slopes and low infiltration rates). 3. Make sure the combination of fertilizers and water will not produce clogging if using a micro-irrigation system. 4. Know how much water is needed to refill the root zone during the irrigation and plan the fertilizer application accordingly. Over-irrigation during fertigation not only wastes ater but could result in leaching of the fertilizer below the root zone. 5. The type of injection device is critical depending on the type of irrigation system being used. Some devices will inject at a relatively uniform rate throughout the irrigation, some will not. Be aware of which type is being used and which type is required by the situation. 6. Be aware of the requirements for flushing the irrigation system after fertigation. This may take 10 to 15 minutes. Also run clean water through the injection meter, discharge hose and check valve. 7.Irrigation systems should be monitored much more closely during fertigation, continuously if possible. 10 Efficient Fertilizer Use — Fertigation: by Dr. Bill Segars 8. Under saline conditions, salinity problems can be intensified by fertigation and improper irrigation management. The level of salinity in soil may itself be increased, even temporarily, by fertilizer application as mineral fertilizers are for the most part soluble salts. Summary When the advantages of fertigation are exploited and the disadvantages are minimized, fertigation can be a very efficient method of fertilization.Although not an end in itself, fertigation can compliment a good base soil fertility program. An understanding of the types of soil, water quality, appropriate nutrient materials, safety precautions, and cropping systems are all important factors in making fertigation useful and economical.

Growing up I've listened to a lot of different music, but to me the one that would remind me of my heritage and home the most would be from Jay Chou. His music is expressive, lyrical, and poetic- all traits of Chinese music and style. I would ask him what inspired his music making and how he plans making music! I would tell him that his music has touched millions of Chinese teenagers growing up and that he has a lasting impact on our generation. One of the first American music I started listening to was Green Day. Their music is aggressively modern and a blast to listen to! It was rebellious and fun, and it really outlined my middle school to high school lifestyle. I would tell them that it was their music that inspired me to work with other talented musicians to play their music as well as bond together. Schubert is without a doubt my favorite classical composer. As a pianist, I've worked with many vocalist that do works of Shubert. His work inspires in me a desire to go behind the musical context and investigate on a more lyrical way, even if it is in a completely different language! Schubert is a crazy man and one can hear it from his music, the cold bloodiness and the craziness is overflowing!! It would be my dream to have dinner with these superstars!

Marty (1955 movie) - Essay Example Choosing a partner in life does not mean choosing who is the best looking amongst the people in town. The main purpose of the rules of self-disclosure is to give therapeutic rewards to people without over-exposing one’s personal life. When a person’s personal life is said to be over-exposed, that personal may feel a bit exploited and get pre-judged by people who barely knew them totally (Roes 22-26). According to Knapp, there are 5 stages of relationship development: 1) initiation, 2) experimenting, 3) intensifying, 4) integrating and 5) bonding. (Suresh, et al., 2) In that pattern, the initiation stage for Marty and Clara was when they had the dance after Clara was dumped by her date for the night. Though Marty got acquainted to Clara’s presence on the wrong note, he was able to make action and a better impression to Clara. Same goes for Clara that though she was crying and was embarrassed by what has transpired. The experimenting stage lasted for many hours that same night. From the Stardust Ballroom dance, they head over to a small luncheonette and further talked. There, they went further to the other stages of relationship development which is intensifying. According to Knapp, this is the stage where it is more of an informal setting in the relationship. Marty and Clara had a talk not about the past anymore but of what they would be doing in the next couple of days, weeks and even months. It is the scene where girls would giggle to see that not all pretty ladies get the better catch and not all good looking males are considered as good catch. It is also the goodness inside of a person that makes them beautiful and pleasant regardless of their outside appearance. They started disclosing more information about their personal life to the other as the other listen attentively as if they would miss information if they would blink. The night ended as Marty was talking Clara to move out of her

The role of advertising in the success of the company Assignment

The role of advertising in the success of the company - Assignment Example This "The role of advertising in the success of the company" essay outlines four various print messages of famous companies and analyze their marketing strategies and their success. Tide is a detergent manufactured by Procter and Gamble. The product takes pride of its reputation as one of the leading brands due to its capability of removing tough stains. Tide is a premium product taking care of the cleanliness and purity of clothes. Instead of focusing on the industrializing India, the advertisers chose to utilize the image of the traditional India and its connection with the laundry detergent. The Ganges River and the Taj Mahal are two important places in the Indian culture. It should also be noted these significant places became major attractions to tourists worldwide. The Ganges River and Taj Mahal is directly associated with purity to Indians according to their religious beliefs. Thus, the communication objective of this advertisement is to make Tide as the detergent which can cl eanse and purify stained clothing the same as how Ganges River purifies the soul and how Taj Mahal portrays pure, unblemished love. This advertisement appears on the magazine Good Housekeeping. This channel is rational because it is most read by housewives who can be more interested on how their household tasks can be made easier by various products. Thus, Procter and Gamble opted to advertise Tide in order to capture this target market. The advertisement shows no definite source but the message is clear—Tide is superior in eliminating stains and whitening fabrics.... This advertisement appears on the magazine Good Housekeeping.

Chanel This simple ad features a blown up image of the beautiful and captivating Eugenia Volodina wearing the new sparkling glasses of Chanel which exudes sophistication and elegance. The advertisement's objective is to inform customers of Chanel's new offerings as well as persuade them to purchase the new product. From its establishment in the early 1910s, Chanel has become an icon of elegance with the brand being synonymous to elegance, wealth, and elitism. Chanel became the ultimate sign of high French class, catering to the needs of elite women. The global popularity of the brand has now made it a top choice for elegant women with very high purchasing power. Thus, the appearance of the ad in Vogue which is recognized as one of the most influential force in shaping fashion and culture is warranted by Chanel's quest of capturing the elite niche. It should be noted that Vogue caters to the same intellectually sophisticated and fashionable females that Chanel are also targeting. The advertisement conveys numerous messages. First, Chanel sunglasses are

Jornal assignment - Essay Example On the other hand, young people have their whole lives ahead of them, so they have all the more reason to vote. Another reason why young people don’t get out and vote as much is because they do not consider it a priority in their lives. Young people aged between 18 and 29 generally have other activities that keep them preoccupied, such as studying, working, or partying. For these first two activities, young people could actually improve their prospects of getting a job or receiving a scholarship to go to university simply by voting for politicians who support education and creating jobs. For the issue of partying, there is not much to do that could change young people’s attitudes because of the particular stage where they are at in their lives. Furthermore, young people may not vote because they constantly move from state to state and so are not registered to vote where they currently reside. Young people often experience great upheaval as part of their lives, and this may mean moving from state to state to try and find a suitable job. Changing over voter registration to another state may seem complicated and too time consuming, and so young people just choose not to update their details. Also, if young people are out of state, then they may not want to send in a ballot beforehand because it involves a lot of extra effort. The key to getting young people to the ballot box is by making things as simple as possible for them. The first way to encourage young people to vote is by providing education about the voting system and what their votes mean to the well-being of the country as a whole. Young people are at a stage in their lives where they are articulate, and so they can understand a reasonable argument that is presented to them in an easy to understand manner. Another way to get younger people to vote is by presenting campaigns to them through a medium that they are already comfortable with. This of course refers to social media such as Facebook

Diagnosis and Treatment Modalities of Triple Fusion

Diagnosis and Treatment Modalities of Triple Fusion Developmental odontogenic anomalies can occur in both primary and permanent dentition leading to morphological variations in shape, size and structure, and numerical variations like anadontia, hypodontia or oligodontia. According to Kramer PF et al the most commonly reported odontogenic anomaly in primary dentition is co-joined teeth. Co-joined teeth can be due to fusion or gemination. Proper clinical and radiographic evaluation is a must to differentiate between the two. Occurrence of double fusion as an anomaly may not be rare, but triple fusion is a rare odontogenic anamoly. This paper gives a brief insight about incidence, problems associated, diagnosis and treatment modalities of triple fusion. INTRODUCTION Completely edentulous maxilla and mandible with only anterior teeth remaining is a common clinical situations causing progressive loss of bone in the posterior aspect of mandible. If bilateral distal extension mandible and completely edentulous maxilla is rehabilitated with removable partial dentures there are chances that mandibular denture base sink gradually because of resorption of alveolar bone in posterior aspect of mandible leading to posterior open bite. Lack of posterior occlusal contacts causes an eventual and progressive shift of masticatory function to anterior segments.1 This syndrome associated with resorption of residual alveolar ridge is termed as combination syndrome. Glossary of Prosthdontic terms 2 defines combination syndrome as the characteristic features that occur when an edentulous maxilla is opposed by natural mandibular anterior teeth including loss of bone from the anterior portion of the maxillary ridge, overgrowth of the tuberosities, papillary hyperplasia of the hard palatal mucosa, extrusion of mandibular anterior teeth, and loss of alveolar bone and ridge height beneath the mandibular removable partial denture bases also called anterior hyperfunction syndrome. Kelly3 was the first person to use the term combination syndrome. Additional changes occurring in clinical situation with completely edentulous maxilla and partially edentulous mandible with only anterior teeth remaining include loss of occlusal vertical dimension, occlusal plane discrepancy, anterior spatial repositioning of the mandible, poor adaptation of the prosthesis, epulis fissuratum and periodontal changes.4 Combination syndrome occurs among 25percent of individuals who wear both complete denture opposing mandibular anterior teeth and a bilateral distal extension removable partial denture.1 Sequelae of combination syndrome: Early loss of bone from the posterior part of the mandible leads to increase in function in anterior region as a result of posterior hypofunction. Hypertrophy of anterior mandible with anterior hyperfunction develops. Forces originating from the lower anterior teeth are directed towards the anterior portion of the unsupported maxillary denture leading to loss of bone and ridge height anteriorly, the posterior residual ridge becomes larger with the development of enlarged tuberosity 3. However enlarged tuberosities is also seen in situations where mandibular molars have been lost, the opposing maxillary molars may supraerupt together with alveolar process.5 Enlarged tuberosities along with increase in bone height causes the occlusal plane to migrate up in the maxillary anterior region and down in the maxillary posterior region, eventually the natural anterior mandibular teeth migrate upward with simultaneous mandibular alveolar hypertrophy. Anterior teeth on the complete denture disappear under patients lip effecting the esthetics showing none of the maxillary anterior teeth and too much of the lower natural anterior teeth. 3 With lack of posterior palatal seal, a negative pressure develops leading to papillary hyperplasia .3 Along with negative pressure chronic occlusal trauma from incisal edges of mandibular anterior teeth causes flabby tissues in anterior palate termed as papillary hyperplasia. Kelly3 demonstrated resorption in the edentulous maxilla but not for the posterior edentulous parts of the mandible. However it has been studied patients with a complete maxillary denture opposed by a mandibular distal extension removable partial denture and retained by an anterior bar revealed more bone resorption in the posterior mandible than in the maxilla.6 Loss of established posterior occlusal contacts is an important factor in relation to the combination syndrome 1as a result of resorption of both anterior maxillary and posterior mandibular edentulous alveolar ridges leads to progressive collapse of vertical dimension of occlusion causing the mandible to move forward resulting in pseudomandibular prognathism. Loss of occlusal contacts can be attributed not only to bone resorption under mandibular distal extension bases but also to wearing of the artificial teeth, as well as changes in position of the anterior mandibular teeth which may facilitate parafunctional activities such as clenching and thereby increasing the pressure on the maxillary anterior alveolar bone.7,8 Histopathological changes: Histopathology of hyperplastic anterior ridge tissue and fibrous tissue over tuberosities are indistinguishable with mature dense fibrous connective tissue consisting of bundles of collagen fibers, few cellular elements and a very few inflammatory cells.3 This is also similar to histopathology of mature epulis fissuratum. Similarity of histopathology of all three conditions (hyper plastic tissue, fibrous tissue, epulis fissuratum) may be attributed to similar tissue response to prolonged trauma from denture base. Management of combination syndrome: Ill fitting dentures have been blamed for all of the lesions of edentulous tissues but the most perfect denture will be ill fitting after bone is lost from anterior part of the ridge. Removable dentures need periodic attention to check for any tissue changes. Frequent relining of ill-fitting dentures slows down but does not stop the development of combination syndrome. Preventing the degenerative changes that complete maxillary denture opposing Kennedy’s class I partial dentures can be best accomplished by avoiding extraction of lower anterior teeth and retaining weak posterior teeth as abutments by means of endodontic and periodontic technique.3Also over denture can be considered as treatment option by retaining roots of anterior mandibular teeth to support an overdenture. According to Langer 9 both well designed removable partial denture and over denture can be suggested for patients with an edentulous maxilla and some remaining anterior mandibular teeth. Well designed mandibular removable partial denture is suggested for low risk patients who have not developed combination syndrome and whose mandibular anterior teeth are well preserved and have not supraerupted. However the restoration of the posterior occlusion with removable partial denture will not entirely delay a progressing combination syndrome. Removable partial denture is advocated for situations that may eventually develop combination syndrome but nevertheless have shown stable occlusion. In the past because of limitations of removable partial denture a more predictable outcome can be expected by use of over denture especially for patients who already have combination syndrome or whose mandibular anterior teeth are structurally or periodontally compromised9 .Additional retention for mandible may be provided by stud attachment. The evaluation of risk of developing combination syndrome is based on past dental history and the condition of remaining mandibular anterior teeth. To prevent bony resorption mechanical forces must be distributed over as large an area of the basal seat as possible and the denture must make as little movement as possible against its basal seat. Wide coverage with the complete or partial removable denture base to minimize the force per unit area is the basic to reduce ridge resorption and would help to prevent combination syndrome.10Covering the retromolar pad and buccal shelf with denture base retards bone loss.10 The destructive changes on the soft tissues brought about by class I mandibular removable partial dentures constitutes a strong support for â€Å"shortened dental arch’’ concept.11Dentures with only anterior and premolar teeth can meet oral functional demands in most situations.12 Surgical options can be considered in treating undesirable conditions associated with combination syndrome .13,14The flabby hyperplastic tissue can be surgically removed, the papillary hyperplasia can be eliminated and enlarged tuberosities can be reduced3 which allows the distal end of occlusal plane to be raised to proper level and allows the lower partial denture bases to be fully extended over the retromolar pad. Correction of premaxillary bone atrophy with bone grafting can be successful in treating combination syndrome. Traditional occlusal schemes and posterior occlusal forms both incorporate a vertical overlap of anterior teeth. Overtime this overlap results in anterior contact or hyperfunction due to forward and upward movement of the mandible leading to bone loss caused by anterior hyperfunction syndrome. An alternative option to prevent contact of anterior teeth involves noninterceptive linear occlusion combined with bilateral fulcrum of protrusive stability.15Linear occlusion consists of masticatory surfaces in the form of a straight, long occlusal ridge in contact with flat monoplane opposing surfaces ,there are no cusp inclines with which to make contact during envelope of function. For this reason linear occlusion is defined as a non interceptive type of occlusion requiring minimal interocclusal rest space.16 Establishing the horizontal plane of occlusion from the incisal edge of the maxillary central incisors to the top of retromolar papilla on either side in the posterior region is an integral part of linear concept of occlusion.16Guidelines for linear occlusion includes use of an alternative tooth form with its inherent absence of anterior vertical overlap.17 There is no need for the traditional 2-3 mm interocclusal rest space which does not mean interocclusal clearance is not needed but less is required. For this reason the centric relation record was made at vertical dimension of rest allowing teeth to be arranged at a vertical height that reduced vertical overlap of anterior teeth, 0.020 of an inch of vertical clearance was provided during arrangement of the anterior teeth.15 Both implant retained and implant supported prostheses have become increasing popular and have been proven successful in prosthetic rehabilitation of partially and completely edentulous maxilla and mandible.18, 19The unstable occlusion in combination syndrome results in progressive posterior mandibular atrophy .use of a conventional denture in restoring the mandibular dentition provides the least patient satisfaction as compared with the fixed prostheses.20For this reason the patient usually elects to have mandibular rehabilitation with implant retained prosthesis. A fixed implant-supported prosthesis of the same design produced bone apposition in the posterior parts of mandible ,whereas an overdenture supported by two implants resulted in a continuous resorption of the same areas .8A well documented long term results were found in fixed mandibular prostheses supported by implants placed between the mental foramina and opposing maxillary complete dentures.21 A study has shown that in patients who received mandibular implant-supported fixed prostheses bone resorption in the posterior part of the mandible ceased.22 Conclusion: Clinicians have recognized a number of characteristic features of combination syndrome but documented observations are rare. Epidemiologic studies related to combination syndrome are yet to be conducted to reach more conclusive results in diagnosing combination syndrome. Destructive changes of hard and soft tissues can be avoided by preventing combination prosthesis by retaining mandibular posterior teeth by endodontic or periodontal treatment. Ill fitting dentures have been blamed for all the lesions of edentulous tissues yet no matter how well the dentures are made by the denture will be ill fitting with gradual resorption of alveolar bone. Removable partial dentures require periodic recall and check up as to maintain posterior occlusal contact by constant relining of distal extension denture base to compensate for resorption of bone. Every effort should be made to avoid the potentially destructive occlusal forces exerted on anterior maxillary residual ridge .Linear occlusal concep t can be used to fabricate functionally and esthetically pleasing prosthesis. Implant rehabilitation in these patients slows down the bone resorption. However management strategies should be tailored to suit the needs of an individual patient.

Free Essays on Invisible Man: Defining Oneself :: Invisible Man Essays

Defining Oneself in Invisible Man Invisible Man by Ralph Ellison is a novel which embodies the universal theme of self-discovery, of the search to figure out who one truly is in life which we all are embarked upon. Throughout the text, the narrator is constantly wondering about who he really is, and evaluating the different identities which he assumes for himself. He progresses from being a hopeful student with a bright future to being just another poor black laborer in New Your City to being a fairly well off spokesperson for a powerful political group, and ultimately to being the "invisible man" which he eventually realizes that he has always been. The deepest irony in this text is that for a significant portion of the story, the narrator is unaware of his own invisibility, in believing that others can "see" him, he is essentially invisible to himself. Only through a long and arduous journey of self-discovery which is fraught with constant and unexpected tragedy and loss does he realize the truth, that his percepti ons of himself and of how others perceived him had been backwards his entire life. The story opens with the narrator participating in a "battle royal" prior to delivering a speech on humility, and on the progress of the Black people. These are the days during which he is still a hopeful scholar, defining himself as a "potential Booker T. Washington." At this point he is living the life that others have told him that he should live, and defines himself as he believes he is seen through their eyes, as an icon of what a Black person can achieve and as a role model for his people. The abuse and degradation which he is put through in the battle royal give him the first inklings that everything is not as it seems, but fail to do anything to change the narrator's perceptions of himself. It is quite possible that if given the chance, the narrator may have gone on living the life that society had preselected for him, and never realized his invisibility, but fate had other plans for him. His entire life was thrown into disarray the day that he was assigned to show around Mr. Norton, a powerful white man and founder of the school that he was attending. The narrator made the mistake of taking Mr.
