Denial Of Service - Essay Example Denial of service attacks is common in businesses and organizational websites. Perpetrators of these attacks target services or sites that are hosted by high profile servers. These include credit card payment systems, banks and root name servers. The article on denial of service attacks that will be used is Dave Neal’s â€Å"Denial of Service Attacks Exploits White House Press Machine†. This article was published in The Inquirer on November 12, 2014. According to this article, attackers used the White House press release machine as a way of gaining network trust. The White House made this discovery when it updated its internet report with a caution that attackers are exploiting the facility’s press release machine. These attackers are using content emanating from the White House to gain network trust. They are using DNS reflection attacks to exploit the press machine. Attackers who target the network at the White House are designing large DNS text records in order to increase amplification, and magnify their attacks. These attackers create their own text records to amplify the responses as required (Neal, 2014). This helps them to direct traffic to targeted sites. The targeted traffic, which is amplified overwhelms the targeted site and makes it unable to respond to requests. In this case, the attacks saturate the target network or machine with amplified external communication requests. These requests come in large number s in order to prevent the machine from responding to legitimate traffic. They also cause the network or machine to respond slowly to legitimate traffic. Denial of service attacks eventually lead to server overload. This technique is effective because the text records have the ability to achieve the largest possible response. The attacks that were observed lasted for 5 hours and created a bandwidth load that peaked at 4.3Gbps (Neal, 2014). The text record technique has been extensively used to target entertainment

Cultural Analysis Essay Example | Topics and Well Written Essays - 1250 words

Cultural Analysis - Essay Example The main objective of the socio-cultural analysis of India is to find out and recognize the potentiality of business opportunities in the country. This initiation would be effective for foreign investors and marketers in understanding the land, its people and cultural diversity before embarking on any international marketing venture in the country. Indian history has a glorious past starting from 2500 B.C. with the Indus Valley civilization (2500-1500 B.C.). The urban civilization was developed on the bank of the Indus river along with the flourishing commerce and agricultural trade. After its decline in 1500 B.C., came the Aryans who migrated from the northwest of the subcontinent and settled in the middle of the Ganges river valley. Ancient and medieval India witnessed the rise and fall of several kingdoms with shifting political boundaries. The most significant unified India was constructed during the reign of the Gupta Dynasty (4th-5th century A.D.), which is more commonly known as the Golden Age of India. The Islamic period came to exist in the country from 10th century A.D. when the Delhi sultanate was established. In the early 16th century A.D., the Mughal Dynasty was established. During this period, India reached new heights in cultural harmony, political administration as well as economic accomplishment in trade and c ommerce. With the arrival of the British (East India Company began a new chapter by initiating trade with India), Modern India witnessed a new political movement as the political power of the country got transferred to the Crown. The political upheavals signaled the beginning of the uprising of a freedom struggle, which was headed by Mahatma Gandhi, the Father of the Nation. On August 15, 1947, India finally got its independence, freedom of becoming a dominion with the Commonwealth after staying in the clutch of the British for almost 200 years.

Investigation of Sphincter Muscle Complex

Investigation of Sphincter Muscle Complex Abstract Background: The exact anus reconstruction is the critical in patients with imperforate anus  which is related to the correct diagnosis of sphincter complex. Objectives: The aim of this study  is exact investigation of the prineal region for ultrasound detection of place and pathway of  sphincter muscle complex. Patients and Methods: This descriptive cross-sectional study was performed at Mashhad  medical university during 2016. Transperineal sonography was done in ten patients (6-12 week  age, 8 male and 2 female) with imperforate anus. Results: The shortest distance between rectal pouch and skin was between 8 to 20 mm, but the  distance between rectal pouch and skin via the anal sphincter path was longer (11 to 23 mm). The multi-layer view of anal tubercle was seen in all patients except one. It had a curved and  occasionally parasagittal path and eccentric than muscle complex. Anal muscle sphincter  complex could be seen in all patients with 2- 3.6 mm, occasionally asymmetric. Conclusion: The multi-layer view of anal tubercle and the anal sphincter complex are the two  important sonographic findings, which can better differentiated the level of anal malformation  and act as an indicator for the location of pull through. Keywords: Anal sphincter muscle complex; Anorectal malformation (ARM); Imperforate anus  (IA); Child 1. Background Colon cancer is a Imperforate anus is one of the anorectal malformations (ARM) which is  characterized with abnormal termination of the hindgut. The anus reconstruction and fecal  continence is one of the critical aspects of treatment and surgery of these patients which is  related to the correct diagnosis of sphincter complex position and the anus reconstruction in the  appropriate place within the sphincter muscle complex . There are various surgical approaches and procedures for anus reconstruction, including the use  of preoperative MRI for diagnosis of type and level of anorectal malformation . In addition, there  are some articles about the use of MRI in the detection of sphincter complex and the anus path  guidance . However, later technique has some limitations and no available in all pediatric surgery  centers. In Imperforate anus (IA) patients, sonography is used to determine the level of disorder (low,  intermediate, high), which may be divided to three groups according to the distance between  perineal skin surface and rectal pouch. However, there isnt an exact cut off for their  differentiation and there is some diagnostic overlap . Some articles consider above 15mm as high  type and below 10 mm as low type ARM , although another numbers between 5- 25 mm are also  considered as cut off point in articles. The passage of rectum from levator ani muscle in  transverse view of infra-coccygeal plan is another method that can help in differentiation  between high and low groups. Furthermore, it is also used for diagnosis of internal fistula  (rectourethral, rectovaginal and etc) which can be helpful in determining level of disorder .   However in practice, these criteria have a little value for operation protocols and the surgical  planning is mostly according to clinical criteria and intraoperative findings.   The exact localization of anal tubercle and muscle sphincter complex with preoperative  sonography can help the surgeon to select the less invasive surgical technique and improve  surgical results. 2. Objectives The aims of this study is exact investigation of the prineal region for detection ultrasonic criteria  of place and pathway of muscle complex and anal sphincter in the children with Imperforate  anus. 3. Patients and Methods This descriptive cross-sectional study was performed at Dr. Sheikh pediatric Hospital during  2016 after being approved by the Institutional Review Board of Mashhad University of Medical  Sciences, Iran and with its grant. In this study, ten patients (6-12 week age) with imperforate anus were selected after obtaining  informed consent from their parents. Nine patients had previous colostomy within the two days  of life and in another remaining one with rectovestibular fistula didnt previously performed it.   Patients were also evaluated for associated congenital anomalies (VACTERL-H and etc.).   The children were placed in lithotomy position and Foley catheter was passed from distal limb of  colostomy to the rectum and the balloon was inflated and retracted backward and fixed. For  better visualization of rectal pouch, normal saline was injected through fixed Foley catheter in  rectum. After prep drape as the first step, transperineal sonography was done by an  experienced pediatric radiologist. Sterile gel and Betadine were used for sonographic window.   The ultrasound devices used in this study was sonosite Model S Nerve with a 12 MHz linear  superficial probe. The sonographic criteria such as shorten distance of rectal pouch from the surface of skin,  distance of rectal pouch from the surface of skin in anal sphincter complex pathway , the  presence of internal fistula, multi-layered view of anal tubercle, state of anal sphincter complex  were evaluated in both sagittal and coronal planes. The Distance between rectal pouch from the  surface of skin in the shortest path and this distance in correlation with sphincter complex were  separately measured. The distance between the rectal pouch and the surface of the skin and the presence of internal  fistula were evaluated in the sagittal sonographic plane. Internal fistulas can be identified by changing of the rout the echogenic mucus of the rectum  toward urethra or vagina. The multi-layered view of anal tubercle is exactly similar to gut signature, and visualized as a  peripheral hypoechoic layer with two central parallel echogenic lines just below the skin  (dermis). It has vertical position than to anal pit (Fig. 1A) and is visible only in coronal plan.   Anal sphincter complex is noticeable as circular muscular tissue in the depth of the subcutaneous  perineal area and is visible in coronal plan (Fig. 1B). 4. Results Table 1 showed the demographic and sonographic findings of ten imperforate anus patients with  were selected for this study. Eight patients were male and other two were female.   The shortest distance between the rectal pouch and the skin surface was between 8 to 20 mm, but  the distance between the rectal pouch and the surface of skin via the anal sphincter path was  longer and between 11 to 23 mm, that it was 3- 8 mm. (4.7 mm mean) longer.   There were rectourethral fistula in 7, rectovaginal fistula in 1, rectovestibular fistula in 1, and in  another one patient no fistula was detected. In patient with rectovestibular fistula, anal sphincter  complex was pushed back toward the coccygeal tip due to fecal material pressure.   The multi-layer view of anal tubercle was seen in all patients except one (rectovestibular fistula  patient). The maximum outside diameter was 3-4 mm, but in patient with cloacal anomaly, it had  about 10 mm in sagittal plan on the posterior of prineal orifice. In often patients, the anal  tubercle path until center of muscle complex had a curved and occasionally parasagittal path and  it wasnt straight (Fig. 1C). The visible length of multi-layer view of anal tubercle was 5-8 mm,  and it attaches to the mucus of muscle complex eccentric or concentric (Fig. 1D).   Anal muscle sphincter complex could be seen in all patients. The muscle complex thickness had  2- 3.6 mm which occasionally was asymmetric (Fig. 1E). 5. Discussion Imperforate anus is a congenital disease with abnormal termination of hindgut which have a wide  spectrum of muscle sphincter complex development (from near-normal muscles to complete  absence of the sphincter muscle). Routinely, depending on the level of the obstruction in above,  middle and below of muscle sphincter, this anomaly is categorized into three groups (High,  intermediate, low type) . The numerous factors especially the fecal continence after the surgery  related to the diagnosis of the exact place of sphincter muscle complex . There are many articles about the role of preoperative MRI in the determining of the type and  level of anorectal malformation which can be helpful in planning and the prediction of the  prognosis and also investigation of the spinal and urethral anomalies which indirectly effect on  the management of disease and operation . MRI has also a role in these patients for  demonstration of the status of sphincter muscle complex, the symmetry of the sphincter, the  perirectal fibrosis . The post-operative MRI is use to evaluate surgical results and the passage of  pulled-through bowel from the center of sphincter complex . Recently, there are some few  articles about the use of MRI in the localization of sphincter complex and the anus pathway as a  guidance instrument . The sonography is usually used to determine the level of disorder (low, intermediate, high)  indirectly basis on the distance between perineal skin surface to the rectal pouch and the internal  fistulae visualization. Although, this approach isnt very determinative and there are a lot of  diagnostic overlap in this field .   In review article, we find only one paper about the detection of the passage of rectum from  levator ani muscle in transverse view of infra-coccygeal plan that can be helpful for  differentiation of high and low groups . The pre-operative exact localization of anal tubercle and especially sphincter muscle complex  with sonography can be helpful for surgeons to select less invasive approaches that determines  the future fecal continence of patient. In this study, with exact ultrasound investigation of prineal region, we noticed two sonographic  findings which can be helpful in patients with imperforate anus to determine the proper path of  anal canal for pull-through operation. These findings were multi-layered view of anal tubercle  and sphincter muscle complex. Multi-layered view of anal tubercle is exactly similar to gut signature and was determined as a  peripheral hypoechoic layer with two central parallel echogenic lines. This view was probably  the result of fetal anal tubercle as a result non-ruptured anal membrane and non recanalized anal  canal. This view wasnt seen in patient with recto-vestibular fistula. Although it had 3-4 mm  diameter, in Cloacal anomaly patient, it had about 10 mm anterior-posterior diameters in sagittal  plan that probably due to fetal merge of anal and vaginal orifices. In most of patients anal tubercle wasnt straight and had parasagittal position and slightly  curvature with eccentric attachment to center of sphincter muscle complex. These can explain  pathophysiology of disease. Anal sphincter and muscle complex was seen as a circular muscular tissue bulk that surrounds  the echogenic mucus of gastrointestinal tract. It was visible on the coronal plane at depth of  subcutaneous fat of the perineal area with 2-3.6 mm thickness. This complex was visible in all of  our 10 patients. In a patient with rectovestibular fistula, this complex pushed backward to the near of coccyx  probably due to fecal retention. Although most patients with Imperforate anus and recto-perineal  fistula categorized as low type, but this patient had high type malformation because the sphincter  complex has been pushed backward and tract of fistula lie above of muscle complex. In this  patient, based on the distance of rectal pouch to the skin (9 mm) and based on clinical findings  alone and without attention to muscle sphincter, the probability of successful surgery was too  low without sonography guide. Then, visualization of the sphincter muscle complex and rectal  pouch is an important sonoghraphic findings in imperforate anus patients that can differentiate  better the patients to the high and low malformation.   In addition, the result of this study shows that the distance between rectal pouch and skin without  attention to muscle sphincter is unreliable and can make a serious pitfalls and unaware  complications. In all patients, the distance between rectal pouch and skin through anal tubercle  and muscle complex (11mm) was longer than shorten distance between rectal pouch and skin (3-8 mm mean: 4.7 mm). In lithotomy position, it is important to notice that multi-layered view of anal tubercle and anal  sphincter complex was only visible in coronal view and was invisible in routine sagittal and  transverse view, then it may be ignored and didnt notice to it in literatures. In the review of  articles, we did not encounter a similar publication about the use of this findings in patients with  imperforate anus, although there are many articles about the use of sonography to determine the  anal sphincter complex in adults in various diseases .   This is a preliminary cross sectional study with the low number of patients. In addition, the  frequency of the ultrasonic probe device were our study limitations. Exact examination of  perineal region with high-frequency probes (14 to 20 MHz) with high amount of the patients can  provide better and more reliable results. Conclusion: The multi-layer view of anal tubercle and the muscular bulk of anal sphincter complex are the  two important sonographic findings, which can better differentiated the level of anal  malformation and act as an indicator for the location of anal sphincter pull through in patients  with Imperforate anus.

Abortion: How Does He Really Feel? :: Essays Papers

Abortion: How Does He Really Feel? In the article, â€Å"End of the Road† by Rebecca Paley, she raises an interesting point of why Dr. William Rashbaum does what he does as an abortion doctor. This article was published in Mother Jones in the Sep/Oct 2003 issue. The setting of this article is placed around modern times. Even though abortion was made legal about 30 years ago, the thought of whether or not it is right is still an issue. This article takes an in depth look inside the life of an abortionist named Dr. William Rashbaum. The audience Paley is targeting are probably people that are for and have had abortions. Paley describes Dr.Rashbum as being an unruly, mad, sometimes compassionate, and doing it because it’s his job type of doctor. She says these things because he doesn’t care about what anyone says. Paley interviewed people that know him personally to give credibility of how he really is. She asked a second-trimester abortion provider who trained under Rashbaum what she thought of him. She stated â€Å"A person who is more concerned with what people think of him than doing the fight thing wouldn’t last. He cares more about doing the right thing than what people think of his personality.† The main argument that Paley is stating is that Dr.Rashbum feels convicted for what he does but, he is only doing it because it’s his job. He even admits that it is hard to do sometime. She makes sure she incorporated plenty of that in her article. Paley also makes this article a little confusing because she jumps back and forth between sides . She tries to justify him by putting little pieces of information that make him not seem so bad. In the next paragraph or two, she makes it seem that he is so wrong for what he is doing. She doesn’t do this directly, but indirectly. The tone Paley uses is a tone that is upset about abortions, but also making excuses for him. She should pick one side so it wouldn’t be too hard to find her argument.

Compare the Ways the Distinctively Visual Is Created in Run Essay

Compare the ways the distinctively visual is created in Run Lola Run and in one other related text of your choosing. Distinctively visual texts aim to manipulate the way we explore and interpret the images we see. Critically affecting the way we make interpretations of the experiences we encounter in the world. The distinctively visual represented in Run Lola Run by Tom Tykwer and the Dove Artificial Time Lapse are similar in some elements. Run Lola Run has multiple distinctively visual features throughout the film, but the Dove ad on the overhand has a few techniques or elements thrown into a 2minute short film. Through Tom Tykwer 1998 film Run Lola Run, he presents visual images and reflects the dominance of post modernism in popular culture at the same time. He has included in the film a set of themes/ideas, which characterise the cultural context: e. g. is Fate versus freewill. The colour red appears throughout the film, as a motif representative of different emotions and ideas central to the film’s core message. Red suggests a sense of passion and freedom from inhibition, quintessentially by Lola’s vivid hair. The colour of Lola’s hair makes her distinctive as the protagonist of the film, as well as symbolising her attitude of defiance towards authority and her individualism. Another motif is circles and spirals in the film, they have been incorporated throughout the film, from the various extreme close ups of clocks to the logos upon buildings and personnel uniforms. Further examples include: the Mercedes benz insignia, the various rings that Lola wears around her fingers, the Bolle sign on the wall behind the phone booth where Manni waits for Lola and the spinning spiral at the Spirale Bar. These circles all symbolises the film’s central message that life is circular and cylical; endings are new beginnings and beginnings mark the end of that which came prior. The image of the spiral is used in the film to represent confusion and desperation as well as the interplay between Fate and our own Free will. For instance, a spiral is used to convey Manni’s confusion about the events of the day prior the call to Lola while he is outside the Spirale Bar. This function as a visual metaphor for the idiom â€Å"his life is spiralling out of control†, a potent reminder of the consequences born of bad decision making or apathy about the outcome of one’s existence. In my related text the Dove Artificial Time Lapse it looks our how the media and we deceive beauty. The ad shows a girl who just looks normal nothing special but is turned into a model by the use of different techniques. Lighting is a key element used during the ad. The beginning when the girl comes in and takes a seat they have used low-key lighting to introduce the subject to the viewer. Once the change begins to the girl the lighting changes, high-key lighting is used to highlight the subject as the transformation happens. Another technique used is movement; this refers to the movement of actors or objects known as kinetics, the movement of the camera and the mechanical distortion of movement. The ad has included mechanical distortion and multiple freeze frames or snap shots of a change in appearance to the girl. They have created this by taking multiple photos to show the motion of the clip at a faster pace. By looking at these two texts you can point out the distinctively visuals created by the themes and motifs found in Run Lola Run and The Dove Artificial Time Lapse. They have incorporated many visual techniques to show both these films; although they are two completely different films you can see the similarities between them.

Benefits of Tricare

With so many different types of healthcare coverages out there it’s not an easy process going about finding the best coverage for those of military service and their family. One of the most important benefits of military service is Health Care. TRICARE is a healthcare program by the Department of Defense that provides health care coverage for medical services, medications, and dental care for military families and retirees and their and survivors.â€Å"The United States Department of defense operates a substantial program to provide medical services to active duty and retired members of the armed forces, their dependents, and their survivors through the Military Health Services System (MHSS)† (Shi & Singh, 2012). â€Å"The MHSS is equipped to provide medical care worldwide† (Shi & Singh, 2012). â€Å"It operates 59 hospitals and 364 clinics to serve an eligible population of 9. 6 million at a annual budget of $50 billion, according to the Department of Defenseâ €  (Shi & Singh, 2012).Since healthcare is so important TRICARE brings together the health care resources of the Army, Navy and Air Force and supplements them with networks of civilian health care professionals to provide better access and high quality service while maintaining the capability to support military operations. Active Duty and Guard and Reserve service members are automatically enrolled in TRICARE Prime. However military dependents and retirees must choose the TRICARE option that best suits their needs.One of the most important benefits of TRICARE is guaranteed insurance at a low premium. More benefits associated with TRICARE includes a broad choice of care providers, no enrollment fee, wide availability and the option of using the TRICARE Extra program, which allows the insured to select any physician, in or out of network. TRICARE also offers the services of military health care and provides supplemental services from civilian health care networks and pharmacies.As a response to the challenge of maintaining medical combat readiness and due to the increasing number retirees while providing the best health care for all eligible personnel, the Department of Defense introduced TRICARE. TRICARE is a regionally managed health care program that brings together the health care resources of the Army, Navy, and Air Force and supplements them with networks of civilian health care professionals to provide better access and high quality service while maintaining the capability to support military operations. TRICARE offers soldiers and their families’ affordable health care when they need it the most.Three main coverages of TRICARE which are TRICARE Prime, TRICARE Extra, and TRICARE Standard and the many different services covered by TRICARE. In conclusion the main challenge for most eligible beneficiaries is deciding which TRICARE option; Prime, Extra or Standard is best for them. Active duty soldiers are enrolled in TRICARE Prime and pay no fees while active duty family members pay no enrollment fees, but they must choose a TRICARE option and apply for enrollment in TRICARE Prime. There are no enrollment fees for active duty families in TRICARE Prime.
