Orthodontic Processes - Essay Example While patient compliance could be a potential aid in this respect, the prospect of white spots as a consequence of enamel deminseralization has had severe consequences for patient compliance and hence overall dental care. In this respect it is necessary that future studies are directed towards development of treatment strategies which are not centred on patience complinace alone. Fluoride varnishes are an upcoming methodology that is increasingly being used to resolve this issue. This proposal shall aim to address this increasingly used method to promote existing orthodontic processes. It has been previously demonstarted that fluoride therapy may have some efficacy in reducing demineralization (O'reilly etal 1987) and indeed in having a protective effect against plaque formation (Ten Cate and Duyster 1983, Silverstone 1978). Furthermore a recent invitro study by Timothy Foley and Manish Aggarwal (2002) has further reestablished the role of protective role of fluoride against demineralization processes. Drawing from these studies it is possible to speculate that flouride varnish if applied on teeth might have some potential for attenuating the deminaralization process (Vivalidi et al Todd et al 1999). The in effect is the working hypothesis underlying this proposal. The primary objective of this study would be to examine whether flouride varnish applied on the teeth might reduce this deminaralization. Given that the fluroide application in the varnish protocol is essentially an anticipatory blocking procedure that does not necessitate patient compliance, it serves orthodontists to gain from the bond strength of composite resins and does not suffer from constraints of development of stagnation areas in the dental environment. Experimental design - Materials and Methods The experimental design is an attempt to study the efficay of flouride varnish (Cavity shield by Omni products) in an invitro setting in preventing/attenuating the demineralization process. The materials and methods that shall be used for this purpose is described below One hundred eighty extracted, caries-free, fully developed molars shall be were selected, cleaned, and stored in deionized water. Care shall be taken to ensure that the potential effect of intraoral topical fluoride on the molars selected for the study would be minimal (ensured by the limited time the teeth remain in the oral cavity). The teeth were polished with fluoride-free dental prophylactic paste to remove any fine debris, rinsed with deionized water, and randomly allocated to the following 2 test groups: group 1, control or vehicle group with no flouride group 2, treatment group with flouride varnish (Cavity shield by Omni products)applied on them . This study design can be shown as presented beneath; Fig 1. Flow diagram showing division of sub groups in the experiment. After allowing the varnish to dry for 5min, all teeth in both groups 1 and 2 were stored in separate beakers of a 200ml artificial saliva solution consisting of 20mmol/l NaHCO3, 3mmol/l NaH2PO4, and 1mmol/l CaCl2, at neutral pH for further processing during the duration of the experimental period. Further to that all teeth in each group shall be removed, rinsed

Thinkertoys Week 3 - Essay Example eeping in view the methodology used by Michalko, it becomes quite easy to explore the problems at individual, collective and corporate levels, and finding out the solutions for these problems as well. Michalko focuses on complete assessment of a problem by examining each and every aspect of it, rather concentrating only one part of the problem, which, according to him, may put the solution of the problem at stake. The same is applied by analyzing one’s personal problems in respect of searching out a job. I have adopted the Phoenix checklist in order to put my questions and their possible answers on the basis of Michalko’s thinking strategy. The solution of a problem is extremely necessary due to the very reality that a problem creates difficulties for a person while thinking and analyzing, so it is very important to make plan to get rid of that problem. The solution of a problem helps the individuals proceed to some goals determined for making progress in life; it is th erefore comprehensive assessment of problem and determining of its all possible solutions is most required for individuals. I have the problem in finding out job as soon as I complete my degree from the university. The declining global economy is the ugliest hurdle on the way of the fresh graduates while penetrating into the job market. In addition, all the organizations demand previous experiences from the job-seekers, which is really a hard nut to crack for the fresh graduates. The analyses of business environment view recommendations and approach a must for entering the job market. Moreover, the rising unemployment at global level has created the proportion of competitors against every vacancy to a great extent. Further, since education has got popularity everywhere in the world, the percentage of educated people has also increased, but the job opportunities are far less than the percentage of educated people, which serves as a serious threat for getting an attractive job. All these points

USB flash drives

USB flash drives The USB (Universal Serial Bus) Flash drives are small storage devices which can store large amount of data in the form of flash memory and are portable. They are available in different sizes varying from 256MB to 64GB. The history to when the USB pen drives first came in existence is quite controversial, however, it is said that the first commercially-available USB flash drive was called the ThumbDrive, it was produced by Trek Technology in the year 2000. Soon IBM came out with its own model known as the DiskOnKey. By 2002, there were several companies which entered the market producing a similar product and marketing it. Pen drives comparatively have a much larger size than a usual floppy disk, which has a maximum data capacity of 1.44MB, or a compact disk, which has a maximum capacity of 700MB. This invention was a vast transformation from the era of floppy disks, as people required a device that would have a larger memory and yet be portable. The previous technology could only be used to store small size data for a short period of time that is 3-5 years, while Pen drives can store much larger size data for at least 10 years and no special care is required unlike in the case of CDs. The latest pen drives consist of a built-in MP3 player and finger print scanners. They only concept of data storage seems to be common between both the technologies. This technology highly attracted consumers as it made large amount of data transfer possible, which would otherwise be very expensive to carry out. This invention can be classified to be a discrete change from the traditionally used floppy drives or compact disks. This is because it was completely transformed by size, shape and its features. Alternatively, since it still belongs to the segment of device for storing memory, it may also be considered a gradual change. Its uniqueness and the fact that it has been further developed and integrated with appliances, like music players and cameras; make it a more discrete change. In the recent years many firms have entered the industry and started supplying the product, there have been gradual changes made to the initial design. The intense competition in the industry is mainly based upon the amount of features provided by each competitor at the lowest rate possible. This is a clear contrast to its initial stage where the degree of competition was low with only a few firms supplying. With the degree of competition increasing in the industry the level of uncertainty has always been high as the companies and the businesses are unaware of what is next? However, the recent upgrades made to the design show comparatively a smaller change in the initial design. It can be said that the product has probably reached the highest point in its growth stage or is entering the maturity phase and thus further developments need to be done for it to survive. The level of uncertainty seems to be declining with the progression in the industry. When speaking of Economic contribution, pen drives have not made any contributions to the economy as such. However, they have had a positive impact on the society as mentioned above, they made large data transfer possible at cheaper rates. The invention of USB flash drives has affected many stakeholders (with respect to IBM); Stakeholders are those group of people who are affected either directly or indirectly by an organisations actions (business dictionary). The ones most affected would be competitors, consumers, suppliers, mangers and shareholders. The competitors are stakeholders directly interested in the decisions made by its rival, IBM. Pen drive was a new advanced product which almost replaced the previous technology thus attracting the consumers to it, who later switched from companies supplying floppy disks and compact disks to IBM, thereby reducing the competitors market share. The competitors then had to incur huge research and development costs and produce a product at least equivalent to IBM in order to retain their market share. The invention also affected the suppliers of IBM. As the technology got older, cost reduction was essential for IBM in order to survive the cut-throat competition. Hence, the sup pliers would have to be efficient enough to supply at reasonable rates. Consumers were amongst the highly affected stakeholders, they are the ones who tryout new products and provide feedback to the companies. They are high risk takers as they initially entered an unknown market as this kind of technology was an entire new concept. Pen drives are no doubt smaller and more compact when compared to compact disks and floppy drives. By compact we mean that they are physically smaller than the latter and are capable of storing larger amount of data. When compared to CDs they are also scratch proof, making them more portable. Latest designs have reduced the size further, as small that it can be easily carried in a wallet. Also some are available with cameras and MP3 players built in them. This factor also shows that it is not resistant to innovation, further improvements and modifications are being done to develop the product further. The development will attract consumers who are more technology savvy; it could also be done to overcome the drawbacks it currently suffers. Over the years the invention has innovated a number of time, however there are drawbacks to this kind of technology also. Despite the fact that the storage capacities have improved over the years not a lot has been done to improve the security of storing information. Many businesses supply their employees with pen drives for them to access work from almost anywhere, thus security is a major issue as important data could be misplaced, if pen drive is misplaced. There is no technique available to track the device or to retain or erase the information on it. Also these devices are not compatible with some operating systems thereby not proving to be efficient enough for the consumers. It can alternatively be argued as they are compatible with most of the commonly used operating systems like Microsoft Windows XP, Mac OS X, etc. A lot of information is stored on a drive and it can be used on almost all the computers, the more it is used on different systems the higher are the chances for i t to contain a virus. This means that if a computer contains virus and a pen drive is attached to it, unless it is write-protected it is very easy for a virus to copy itself on a pen drive and attack other computers. This again reduces security of information as some anti viruses often delete the virus affected file, therefore essential information could be lost. The technology may be getting better each day but the new releases and latest pen drives are very expensive. This can also be considered to be a disadvantage as the consumers are unable to buy it and by the time they do a better version of it is available. As far as personal experience says, pen drives have a slower transfer rate when compared to hard disks. However, the size factor nullifies the impact as pen drives are much smaller and portable. It could also be one of the future development possibilities for the businesses to make it even more sleek and stylish. They could enhance its security by probably adding an auto-lock code to it, so if it is in wrong hands it would probably lock itself and be of no use. They could also work on the transfer rate and increase the storage capacity to around 1 tetra byte.

Not including all the extra activities like sports, clubs and church that teenagers like myself are involved in. I believe people usually end up acting like the people they hang around with. â€Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) My grandfather always used to say, â€Å"Show me your friends, and I’ll tell you who you are†. Drs. Davis, Jenkins and, Hunt also say this in their book, The Pact, â€Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) . Although, it’s helpful to â⠂¬Å"Friends play a big role in determining who you are and how you dress and talk and act†. (Compton 1 of 2 Peer pressure) . When you are constantly surrounded by people with the same goals as you, and are going through the same problems it feels normal to involve yourself in what they are doing, because you feel like you are in the same â€Å"boat†.

Sex Education at School level

To subjugate a nation or a country destroy its literature, its history and above all its culture. This is what the English men do to tighten the bonds of slavery on India. And we Indians are making merry over the ruins of our ancient culture and civilization.Our Rishis who were scholars, thinkers, preachers, philosophers and warriors as well had divided human life into four periods. According to them average expectance of life in India was 100 years. First twenty five years period was meant for physical, literary and spiritual education, second thirty five years i.e. up to the age of sixty years were meant for family life then Vanprasth and finally sanyas. For the first twenty five years one and the foremost and compulsory principle was â€Å"Brhamcharya† meaning self restraint over sexual feelings.A Brahmchari who was primarily a student, a vidyarthi and a pupil of the Guru would never think in terms of sex. He was taught not to distinguish between male and female. To him all females were either mothers or sisters. He was forced to believe that breasts of a lady are but a loath of flesh and fat, a sort of deformity not a center for attraction. And with this type of education we have the proud privilege of having great personalities like Swami Ram Kishna Paramhans, Swami Vivekanda, Swami Ram Terth, Subhash Chand Bose, Swami Dayanand, Jagat guru Shankracharya not in distant past while great men like Bhishma Pitamah of prehistoric days.Even today we have a number of leaders both male and female who have followed the sacred path of Brahamcharya and are outstanding personalities in every field of life. The names of our president A. P. T. Abdul Kalam and Atal Behari Vajpayee ex. Prime minister may be cited as examples. Now under the influence of western civilization there is a talk of imparting sex education at school level. A simple question to the advocates of sex education?Sex in not a characteristic of human beings only. It is found practically in all liv ing animals, birds, insects and even in plant kingdom. Who teaches sex to cow or a buffalo or a donkey or a bird or an insect. Sex is a natural instinct and needs no lesion, no teaching and no demonstration. Sex in animal and plant kingdom is not rampant. It is controlled by nature. But sex in human has to be controlled by self restrain, by teachings and creating an atmosphere adverse to the feelings of sex i.e. following the path of Brahmcharya.Premarital  sex is a crime. Bigamy is prohibited by law as well as by society and also by religion. After all what is the purpose of sex education? Under guise of AIDS the advocates of sex education plead for its necessity. But when sex is prohibited no doubt but if you at all indulge then there are safety measures therefore. It is just like telling a thief that committing theft is illegal but in case you do it, adopt safe ways. One thing more. There is growing trend of co-education at school level. Just imagine a female unmarried teacher teaching lesion on sex to a class consisting of boys and girls or a male teacher doing the same job in his class. How would the advocates of sex education face such a situation? Is it at all advisable or practicable? Hence we should stick to our cultural traditions and should provide such education as would arouse in them a feeling of an urge for moral traditions of India culture.Lessons highlighting the importance of morality should be including in text books of English and Hindi literature as also in curriculum of subjects like History and Civics. An independent discipline of moral ethics may be given to the students in the prayer meetings and the students must be given & chances express their feelings and expose their learning. Physical training must also be introduced as compulsory subject and fruitful training of YOGA may be imparted to the students. YOGA may also be made compulsory for scouts and N.CC. Cadets. It is a time that we arise to the occasion and save our children fr om the malicious feelings of sex and infuse in them the sprit of self restraint so that the idea of sex may not enter into their mind’s horizon. Therein lies the salvation of our society and the country at large.

!0 Mary Street Short Analysis

10 Mary Street Analysis 10 Mary Street is a poem by Peter Skrzynecki, appearing in Migrant Chronicle. The poem discusses family, connection to place and the impacts of Peter’s own migrant experience. Skrzynecki details richly impassioned recounts told in snippets of symbolism, imagery and throwbacks to the pre-war European environment Skrzynecki’s family belonged in. * The first stanza depicts the habitual routine of Skrzynecki’s family, as indicated by the use of the phrase â€Å"Each morning† in the third line. This helps evoke a clear sense of normal practice and routine in the lives of the Skrzynecki family.Additionally through the use of industrial imagery; â€Å"rusty bucket†, â€Å"bridge†, â€Å"factory† the audience can see a sense of comfort and connection to their humble surrounds. * The second stanza presents the strong connection that Peter’s parents share with their garden. But while Skrzynecki’s parents tak e fulfilment in nurturing and fostering the garden (Tended roses and camellias/ Like adopted children), Skrzynecki himself didn’t hold the same values as his parents (I’d ravage the backyard garden/ Like a hungry bird).This contrasting use of simile accurately depicts the sort of cultural background Skrzynecki feels he doesn’t belong to. * The third stanza discusses the connection to the 10 Mary Street address that his family holds. The use of personification in the first line; â€Å"The house stands† highlights the human value of the house and establishes a strong sense of belonging to the house. Additionally, the use of Cumulative listing lines in 13-17 helps to reinforce the family’s strong connection to their European heritage. The final stanza presents a contrasting view of belonging whereby Peter feels his family â€Å"became citizens of the soil/ That was feeding us† and indicates a sense of comfort and acceptance of the Australian wa y of life. The last 3 lines: â€Å"Inheritors of a key/ That’ll open no house/ When this one is pulled down. † Re-establishes what the house symbolised for them and the notion that the sort of connection 10 Mary Street had to their new lives in Australia will be a challenge to recreate.
