Anterior Crucient Ligament
The Anterior Crucient Ligament also known as the ACL is usually injured in a forceful twisting motion of the knee. It also may be injured by hyper extending the knee witch is when the femur is forcefully pushed across the tibia such as a sudden stop, while running or a sudden change in weight. The person will feel or here a sudden pop in the knee. The knee may or may not get very swollen, but the knee will be very unstable so you can not walk and it is painful especially when it is moved after the accident.
The anterior crucient ligament is a band of tissue which has two major strands is in the center of the knee and it crosses the posterior crucient ligament and extends from the back of the femur to the front of the tibia . The ACL’s purpose is to give you the ability to stand and walk and prevents the tibia from moving
forward. Two months after I had surgery on my meniscus, I went snowboarding and crashed into a tree. My right leg was stuck in my binding and the board twisted and I felt a sharp pain and fell to the ground, but I got up and kept going. After the season was over I went to the doctor and got an MRI scan, it showed that I had torn my ALC.
Sometimes the UCL will weaken and stretch (technically a sprain), making it incompetent. Other times a catastrophic stress will cause the structure to "pop" or blow out. The injury isn't tremendously painful, and it can be incredibly diffic...
In spite of this the rate of ACL injury is almost equal through all levels of sports, from beginner, to recreational, to professional athletes. The most widely publicized incident of ACL damage has come from Theresa Edwards who was a top female athlete. She was a basketball player who went to the limit with sports. She went beyond her capability and her ligament couldn’t withstand the pressure and snapped. She is not the only but just one example of many who have suffered this same problem. As female athletes continue to become more competitive and aggressive, ACL damage continues to rise.
...ulation respectively. In terms of assessment, hemophilia is suspected in children with excessive bleeding, easy bruising, spontaneous hematuria, and epistaxis (Ignatavicius & Workman, 2009). A low prothrombin and bleeding and low factor VIII in indicative of hemophilia A while an extended thromboplastin time and low factor IX is indicative of hemophilia B. Hemophilia is a lifelong disease and treatment regimens are aimed at reducing the signs and symptoms associated with it. Type A and B are managed with supplementation plasma concentrate Factor VIII and factor IX respectively, liver transplant, and gene therapy (Colbert, 2009).
Emma Goldman’s Free Speech Fights served to not only emphasize the problems with the time period, but also served to illustrate her true character. Censorship and repression were large themes of the century. Goldman worked hard to attain equality through speech rallies and demonstrations, despite the charged hatred that she was met with. Nevertheless, Goldman was not the immortalized martyr that she is portrayed as. Through the time period, even she felt censored. She felt as if she could not speak her mind in regards to her emotions. Thus she liberated herself emotionally through her letter writing to her closest confidants. But Goldman’s struggle to uphold the first amendment begs the question: if this country is built on the foundation of equality, then how free really is free?
A 16-year-old, female high school soccer player, Lindsey Robinson, tore her anterior cruciate ligament (ACL) during a soccer game. Interestingly, she was not the only one in her team who injured her ACL, but several of her teammates have torn the same ligament as well during the soccer season. Lephart (2002) found that women involved in physical activity are more susceptible to acquiring the ACL injuries than men who are involved in the same physical activity (as cited in Ogden, 2002). According to “ACL Injury Prevention” (2004), the numbers of female ACL ruptures have increased for the past ten years. Over 1.4 million women have suffered from the ACL rupture, which is twice the rate of the previous decade.
The majority of ACL injuries suffered during athletic participation are of the noncontact variety. Three main noncontact mechanisms have been identified planting and cutting, straight-knee landing and one-step stop landing with the knee hyperextended. Pivoting and sudden deceleration are also common mechanisms of noncontact ACL injury. Basketball, soccer, and volleyball consistently produce some of the highest ACL injury rates across various age groups. Other activities with a high rate of injury are gymnastics, martial arts, and running. In most sports, injuries occur more often in games than in practice. Many injuries have occurred during the first 30 minutes of play. One-reason physicians are seeing more ACL injuries in female patients that more women play sports, and they play more intensely. But as they continued to do more studies, they are finding that women's higher rate of ACL is probably due ...
World War II killed more people, destroyed more property, disrupted more lives, and probably had more far-reaching consequences than any other war in history. It brought about the downfall of Western Europe as the center of world power and led to the rise of the Soviet Union. The exact number of people killed because of the war will never be known. Many nations came together to form the Axis. As they’re opposite the Allies totaled fifty nations by the end of the war. The early stages of the war are what got the attention of the U.S. Although, the U.S. was set on being on the sidelines of this war, Pearl Harbor was the deciding factor for her entry. The consequences of the war involved numerous deaths and even more power struggles after the war had ended. All together, World War II was a far-reaching, extremely destructive war that changed the world and its super-powers forever.
Hemophilia is a genetic disorder in which the blood does not clot normally. It’s a rare bleeding disorder that has been happening since ancient times. Men are the ones mainly affected by it. One in five thousand men born each year have Hemophilia. Yet women can be carriers and just like men, they can suffer from symptoms too. Women can only have Hemophilia if their father does and mother is a carrier, it’s uncommon but can happen. Hemophilia affects all races and ethnic groups. It’s all based on your family tree. A man with Hemophilia will pass the gene down to his daughters, leading to them becoming carriers. A woman with the gene has a fifty percent chance of passing the gene down on to her sons. If there was no family history of Hemophilia but the woman is a carrier, a son could possibly be the first one in the family to have it. If there’s one thing for certain about hemophilia is that it does not discriminate against anyone. Hemophilia has affected royalty as well as high and low class men all throughout history.
Hemophilia is a serious genetic condition caused by a coagulation factor that causes a mutation in the f8 and f8 gene. Hemophilia can be treated but not cured. Further studies are currently being done today. Living with hemophilia can be very difficult .physical activity is not recommended for individuals living with this condition. Also surgery is highly dangerous because of the excessive bleeding. In society we have set backs but we have to learn to deal with them.
Since the No Child Left Behind Act has come into effect, it has caused some concerns with teachers and parents alike on how well it is working for the students. There have been issues to be addressed and instead been overlooked. Because in “Is No Child Left Behind Effective For All Students?” Parents Don’t Think So, a school who fails to meet Adequate Yearly Progress (AYP) for four or more years is considered under corrective action and the state board must make serious changes to the school. Randolph and Wilson-Younger, (Oct. 22, 2012). Our government has offered states the chance to waive requirements but the states have to make specific reforms in exchange for flexibility. During the first round of waivers offered, 11 states applied. The states had to fill out applications. Each state must put in an application for a waiver and if a state receives a wavier it will last for two years and then they can reapply. These waivers are needed because the No Child Left Behind is broken. The laws can identify which schools that are in need of improvement based on their achievement targets. The law prescribes interventions but the interventions are not working as well as they could be. Lawmakers have proposed to move a bill to the Senate or House floor. However, the Republicans had p...
The purpose of this paper is to elaborate on the No Child Left Behind Act, and how the accountability of testing subgroup provisions may play a major role on the responsibilities of a student’ education. The paper also focuses on what information parents are receiving to actually know how their student(s) are performing in class and whether each student’s performance is within state compliance with NCLB.
Hemophilia is an inherited disease which slows the blood clotting process due to missing or reduced clotting factor proteins. Although uncommon, it is possible for Hemophilia to be acquired if the body produces antibodies that attack clotting factors. Only 30% of Hemophilia cases are due to spontaneous mutations. Hemophilia is a rare disorder. Approximately 1 in 5000 males has Hemophilia. The disorder is much more common in males than females. It is estimated that over 400000 individuals worldwide (.006% of the world’s population) have Hemophilia (National Hemophilia Foundation). Individuals with Hemophilia do not lose blood at a faster rate than others but they do bleed for longer. Small cuts and bruises are not usually life threatening but any serious injury or invasive surgery has the potential to be life threatening because of this disorder. Hemophilia can also cause internal bleeding, which can cause organ or tissue damage. This can be life threatening as well. There are two types of Hemophilia. Hemophilia A is due to the individual producing low levels of clotting factor VIII while Hemophilia B is due to the individual producing low levels of clotting factor IX. Clotting factors are proteins which interact with platelets so that clots can be formed. Clotting factors allow the platelets to clump together to seal cuts and tears in blood vessels to prevent excessive bleeding. Hemophilia can be mild moderate or severe depending on the amount of clotting factor in the blood. Individuals with mild Hemophilia have 6% to 49% of the normal amount of clotting factor. Individuals with moderate hemophilia have 1% to 5%, while those with severe have less than 1% of the normal clotting factor (National Hemophilia Foundation). Indivi...
Hemophilia is a rare genetic blood disease characterized by the inability or impairment of blood to clot or coagulate when a blood vessel is broken. This inherited disease is caused by an insufficiency of blood proteins, known as factors, which participate in blood clotting often by sudden gene mutation. Hemophilia can be characterized into three distinct types, including Hemophilia A, Hemophilia B, and Hemophilia C. Biologically, hemophilia is a unique genetic disorder that
As stated in the Code of Hammurabi, “an eye for an eye, a tooth for a tooth”, this was the notion that for every undesirable act that was done, there should be an equal punishment given (The Phrase Finder). The code was also based on the rule of law, which ultimately states that no person is above the law. Furthermore, in terms of diplomatic immunity, before looking at the problems of it, we must first establish the history of it. Some might ask, what is a diplomat? Well according to the dictionary, a diplomat is “a person appointed by the government, to conduct official negotiations and maintain political, economic, and social relations with another country or countries” (“Diplomat, 2014). Some other duties of a diplomat include, promoting relationships between different countries, protecting the interest of the home country with the host country, and representing the home country in the host country (E Diplomat). Above all, it is a fair statement to say that, diplomats truly have a special job position. Along with the duties diplomats have to preform, they are also protected and exempt from all laws, while in the host country and this is ultimately known as diplomatic immunity (Tunks, 2002).
Hyatt had initially tried using collodion - a natural substance. After he had spilt a bottle of it he discovered that the material dried into a tough and flexible film. The substance that was recovered was not strong enough to be used as a replacement for billiard balls, so they then added camphor. This became known as Celluloid. Celluloid also became wel...
