The Mexican War and Manifest destiny - Essay Example This encouraged western expansion, with the ultimate aim of controlling the entire North America. The federal government policy also served as an incentive to the expansion of the west. This can be related to the Homestead Act of 1862 that encouraged the development of the agricultural west. Another incentive for the expansion of the west was the development of transportation. The economy of the west was based on cultivation of cotton. As a result, the canal system developed because of steam boats. Development of railroads also played a significant role in the development of the west. For example, the transcontinental rail road played an essential role in the growth of the population and trade (Mountjoy, 2009). Despite the expansion of the west, several factors can be associated with the opposition to the expansion. The expansion of the west faced massive opposition from anti-slave Northerners, who believed that additional territories would encourage the legalization of slavery. They purported that western expansion would ensure that slave states outnumbered slave free states. As a result, this would lead to legislation that would favor slavery (Meed, 2002). Although some Native Americans, such as Indians, opposed the expansion of the west, American settlers defeated them. They could not withstand the movement of thousands of settlers because the army defeated them in a number of battles. They were also confined into reservations; the US president, Andrew Jackson, passed the Indian removal act, which encouraged coercive removal of

Keywords: Dental Camp, Dentures, Public health. INTRODUCTION Dental Camps in India are being routinely conducted. The main objective being awareness, education, and motivation of the common man regarding his/her dental health. Dental camps usually are conducted for a large population who do not have accessibility for a sophisticated dental treatment and for the people with financial constraint. Camps can be conducted for screening or for treating the patients like extractions, restorations and/or fabrication of dentures. Screening and treatment camps held for extractions, restorations does not require a lot of equipments and man power on the other hand; fabricating a denture for the patients require a lot of equipments and instruments. When treating a vast population in camps, it calls for more number of instruments, equipments and lot of manpower in terms of doctors, dental mechanics and supporting staff. Public health work exhibits a certain number of characteristics that are different from individual practice in the same field. Most important is the fact that the public health work must be done in areas where the group responsibility is recognized. Another characteristic of public health method is its reliance upon the team work. This is due to the necessity of efficient handling of large group of people. This report presents the efficient way of conducting a denture camp and tackling the short comings faced during the course. Materials and Methods A denture camp was conducted by the Department of Prosthodontics, Government Dental College and Research Institute Bangalore, at Gundlupete, Chamarajanagar distric on 9 and 10th of Feb. 2013 Gundlupete, is a small town with a population of 28157 situated 200 kms from Bangalore. The villagers are hailing mostly from poor families, with a very limited knowledge and accessibility to their basic health maintenance needs, especially dental health. For this reason this particular village was chosen by the Department of Prosthodontics, Government Dental College and Research Institute, Bangalore to render denture services to the poor and needy patients. Indian Medical Association Gundelpet took the responsibility to provide the services, like accommodation and food for the team. An announcement of the denture camp was made in the village by a local body one month prior to the scheduled date of the camp. Audio aids like public addressing systems/microphones and visual aids like pamphlets were used for the public awareness regarding the camp [1]. Enlightening the people about the Dental health is a must in such a town, so awareness was made. People were instructed through these aids to attend the preliminary screening which was held on held on 9th Jan 2013 for which a team of doctors with required diagnostic aids were deputed from the college. It is an achievement in the history of Government Dental College and Research Institute for having screened 300 patients. Out of 300 patients, 110patients were selected for the denture camp. They were informed to come early morning at 8a.m on the scheduled date and make necessary arrangements for their stay for one night during the camp as the most of the patients were from surrounding villages. The doctors had so much o f keen interest to render the services for selected 110 patients who had come from different parts of the village. A list of all the necessary equipments, materials and instruments with their quantity was made for the fabrications for 125 dentures. Required materials and equipments were collected from the college stores. Chair-side instruments, diagnostic instruments, lab equipments were collected from the staff and students of the Government dental college and research institute. A total of 100 clamps and flasks and 115 articulators were procured. Ten micromotors were collected, of which 5 were from the department and the rest were borrowed from the other departments. Local organization was so kind enough to take the responsibility of providing two gas cylinders for the lab-work. 4 â€Å"T† attachments containing 10 burner gas connection points each were taken from the Department. The collected materials were sorted out in an orderly manner and were packed in the cartons. There were 20 cartons containing equipments and materials. These cartons were numbered and a list containing all mater ials in a particular carton was made and pasted on each of them. A copy of the same was made and kept with a particular volunteer for easy access and to avoid confusion. 3 mini buses containing a team of 55 dentists, 55 dental mechanics and five supporting staff left to Gundlupete on 8 th morning . The dentist’s team consisted of staff including the Dean cum Director, Post Graduate students of the department and the house surgeons from various other departments who volunteered to be a part of this denture camp. The dental mechanics team consisted of dental mechanics from our institution and also from various other dental colleges. After reaching the camp venue ( primary school in gundlupete) rooms were selected for the clinical work, one for the lab work and plaster work was carried out in the open ground in front of the class rooms. Plastic chairs for seating the patients, tables for the dental technicians, gas assembly, huge containers for dewaxing and acrylization were arranged on the same evening. On the 9th morning the camp started at around 8 a.m. All the patients were registered and were given a token to come in queue to avoid confusion. On the token the patients register number and all the clinical steps involved in the denture fabrication with the assigned Doctor’s and technician’s name were mentioned. Along with each mentioned clinical step, space was provided to indicate the step which has been completed for the patient. Dentist and technicians were divided into 11 groups comprising of 5 dentists and 5 technicians in each group. Primary impressions for all the patient’s were made with high fusing impression compound and subsequent wash impression with irreversible hydrocolloid were made. For the patients with poor alveolar ridges special tray were fabricated, border molding was done using putty and subsequently secondary impressions were made with Zinc oxide eugenol. All the primary impressions were numbered according to the number given to the patient. The same numbers were transferred on the casts. Record bases were fabricated using shellac base plates. Occlusal rims were fabricated on the record bases using modeling wax. Lost Occlusal vertical dimension and centric relation were recorded using a static method and shade selection was done. Teeth arrangements were done by the technicians. The try-in was done and the trial dentures were returned to the technicians for the acrylization. Then the patients were asked to come next day morning for denture insertion. Once the patients were dispersed the dentists also joined the technicians for the lab work like sealing of the trial dentures, flasking, dewaxing, acrylization, finishing and polishing procedures. The register numbers were incorporated in the dentures during the trial closure. The whole team worked till all the dentures were processed which went on day and night without taking rest, the team of doctors did not sleep at all, on such herculean line worked till rising of the sun. Deflasking, trimming, finishing and polishing of the dentures were done the following day. All the required chair side trimming was done and denture insertion was carried out. Post insertion instructions were given to the patients in groups and the written format was distributed to each of them. Most of the dentures had satisfactory retention and stability. Patients were comfortable and satisfied. One or two patients who had compromised retention in their dentures due to poor alveolar ridge were instructed to use the denture adhesives. The patients were advised to come after a week for the follow up for which a team of three dentists was deputed from the college. Some of the patients had developed soreness which was relieved and some minor occlusal corrections were carried out. Discussion In developing countries like India , majority of the population lives in villages were providing basic health facilities is a Herculean task. The worldwide prevalence of dental disease is a constant reminder of the almost universal need for effective dental health programmes. These programmes should be routinely conducted for the betterment of the patients. Conducting a successful camp, especially denture camps include assembling the manpower, finance, materials, equipments, instruments, coordination and generous mind of the team. Denture camps unlike the routine camps, require a lot of time, effort, equipments and co-ordination. Treating the edentulous poor patients in camps provides them with dentures which they cannot afford due to financial constraint. Through these camps it is possible to rehabilitate more number of poor patients in short span of time. Rehabilitating the poor edentulous patients improves their appearance, confidence, health and overall well-being. Further, the quality of treatment provided may not be of high standards as all the clinical steps cannot be done due to time constraint, but the treatment given was the stepping stone to make them know the importance of teeth hygiene and to avoid further complications. Active participation of the local organization is very important for the success of the camp. They play a key role in informing and throughing light on their souls how important the camp was to save them from further decay in life. Arranging the venue for the camp, accommodation and food for the team, should also be taken care by the local bodies for a camp to be successful. Success of the camp depends upon the support and co-ordination of the local bodies. Problems were faced as we had only 100 clamp and flasks, the denture processing steps had to be repeated. The number of patients exceeded our estimate, because of which we informed the unregistered patients to undergo the treatment next time. Conclusion Dentures are no more a luxury; it has become a necessity for the edentulous patients for the basic health maintenance. Denture fabrication in a camp requires lot of efforts, manpower, equipments, coordination and support of the local body. Many problems were encountered during this camp. Though there were many hurdles but the doctors became successful in treating the patients. The mountains may look high, but when we begin to climb and reach the top we say it is not so high. The team had taken a brave step with all the problems and they ended with a happy note. In spite of all the problems faced, the dedicated team work proved fruitful in rehabilitating 132 patients in short spans 24 hrs. The efforts of team were highly appreciated by the people.

Internet Explorer SSL Vulnerability :: essays research papers

Abstract Internet Explorer's implementation of SSL contains a vulnerability that allows for an active, undetected, man in the middle attack. No dialogs are shown, no warnings are given. ======================================================================== Description In the normal case, the administrator of a web site might wish to provide secure communication via SSL. To do so, the administrator generates a certificate and has it signed by a Certificate Authority. The generated certificate should list the URL of the secure web site in the Common Name field of the Distinguished Name section. The CA verifies that the administrator legitimately owns the URL in the CN field, signs the certificate, and gives it back. Assuming the administrator is trying to secure www.thoughtcrime.org, we now have the following certificate structure: [CERT - Issuer: VeriSign / Subject: VeriSign] -> [CERT - Issuer: VeriSign / Subject: www.thoughtcrime.org] When a web browser receives this, it should verify that the CN field matches the domain it just connected to, and that it's signed using a known CA certificate. No man in the middle attack is possible because it should not be possible to substitute a certificate with a valid CN and a valid signature. However, there is a slightly more complicated scenario. Sometimes it is convenient to delegate signing authority to more localized authorities. In this case, the administrator of www.thoughtcrime.org would get a chain of certificates from the localized authority: [Issuer: VeriSign / Subject: VeriSign] -> [Issuer: VeriSign / Subject: Intermediate CA] -> [Issuer: Intermediate CA / Subject: www.thoughtcrime.org] When a web browser receives this, it should verify that the CN field of the leaf certificate matches the domain it just connected to, that it's signed by the intermediate CA, and that the intermediate CA is signed by a known CA certificate. Finally, the web browser should also check that all intermediate certificates have valid CA Basic Constraints. You guessed it, Internet Explorer does not check the Basic Constraints. ========================================================================== Exploit So what does this mean? This means that as far as IE is concerned, anyone with a valid CA-signed certificate for ANY domain can generate a valid CA-signed certificate for ANY OTHER domain. As the unscrupulous administrator of www.thoughtcrime.org, I can generate a valid certificate and request a signature from VeriSign: [CERT - Issuer: VeriSign / Subject: VeriSign] -> [CERT - Issuer: VeriSign / Subject: www.thoughtcrime.org] Then I generate a certificate for any domain I want, and sign it using my run-of-the-mill joe-blow CA-signed certificate: [CERT - Issuer: VeriSign / Subject: VeriSign] -> [CERT - Issuer: VeriSign / Subject: www.thoughtcrime.org] -> [CERT - Issuer: www.thoughtcrime.org / Subject: www.amazon.com] Since IE doesn't check the Basic Constraints on the www.thoughtcrime.org certificate, it accepts this certificate chain as valid for www.amazon.com. Anyone with any CA-signed certificate (and the corresponding private

Identify the lesson as, primarily, a review of information that many students learned in earlier grades. Explain that being well-grounded in knowledge about the reproductive system will help them make sense of discussions later in the unit about pregnancy, birth control, and sexually transmitted diseases. Also, if they have health problems in the future, knowing body parts helps them explain to a health provider what they think the problem may be. 2. Brainstorm with the class about body parts. Write on the board in three columns: Male / Female / Both. Ask students to name reproductive system body parts, both internal and external, in the three columns. Fill in from the Teacher Master List (below) the parts that students don’t mention. As you list the parts on the board, briefly define each body part, where it is in the body and what it does. 3. Use Reproductive System Visuals 1-6 to continue reviewing the male and female reproductive systems, including the location and function of each part. Use a document camera (or SMART Board, overhead projector, etc) to project the images on the board.

Death Penalty Should Be Abolished Essay

The death penalty is a cruel and uncivilized way of keeping crime down to a minimum, by killing anyone who commits a horrible crime such as murder. The most common way of being killed while on death penalty is lethal injection. The death penalty does not change murderers minds whether they should kill someone or not. If people have a mental illness and are psychopaths and enjoy killing i’m sure they never think to themselves and say if I do kill someone then I will go to jail and then be killed. They go through with the murder because that’s what they intended to do from the start. Also in Europe there is no death penalty and research shows that the murder rate is drastically lower than the USA. This shows that the death penalty does not scare murderers out of doing what they want to do. The death penalty is not the best protection form a murderer. It may be the best protection from a specific murderer if he is going to be killed with death penalty because he will not live anymore and so he wouldn’t be alive to kill you. But if you are trying to protect yourself from being murdered the death penalty will not help you at all. It would be like telling someone, while they are in the middle of murdering you, that they shouldn’t do it because once the police find out they’re going to have the death penalty! The murderer would not stop at nothing if his mission was to kill you. Justice for the victim is not achieved through the death penalty. Justice is not achieved because if a man murdered a the son of a husband and wife, and the son was killed, the son is already dead. Just because the murderer is sentenced to the death penalty doesn’t mean that their son will magically come back to life and be the same person he was. He is dead and the murder of the murderer will not do anything but give the husband and wife revenge. To conclude the death penalty should not be allowed there is no perks or cons of having it. It gives no justice to anyone, it isn’t a very effective way of scaring anyone and it most likely wont protect you from any murderer.
