Background
Tibial Tuberosity Advancement (TTA) is an othopaedic procedure to repair rupture of cranial cruciate ligament (CCL) in dogs. It has also been applied in cats. The canine CCL is a band of tough fibrous tissue that attaches the femur to the tibia. It is attached to the interdylar notch of the tibia at one end and the caudomedial part of the lateral femoral condyle at the other end. It keeps the tibia from sliding cranially beneath the femur when the limb bears weight. It also limits medial rotation of the tibia when the stifle is flexed [1]. These help to prevent the stifle joint from over – extending or rotating.
The rupture of this ligament in dog is not suddenly broken due to excessive trauma, but usually degenerates slowly over

Material
After the model was imported into Abaqus, the mechanical properties earned from the prior process were assigned to the model. In addition, as the model is assumed as a homogenous structure, then the highest values of all mechanical properties were used as a representative of all structure. These properties are density of 1813 kg/m3, young modulus of 4993 MPa and Poisson coefficient of 0.3 (see figure 4).
Interaction
This part is the most important of the analysis because fissure and fracture cannot be observed without given fracture mechanics. Therefore, the crack propagation of this study can be studied using XFEM method. This method will define the model as a crack domain, but the crack cannot be propagated without crack initiation. A crack tip was placed at the location where the highest stress was concentrated on. In our study, the highest stress was located at cylindrical wall of maquet hole at approximately 225 from X+ axis when determined in XY plane as shown in figure 7. The crack tip is a very thin surface placed on the model associated with the centre of the maquet hole in XY plane. This tip has 0.5 mm. overlap into the cylindrical wall of maquet hole as shown in figure
Monkeys and humans have been compared for years, we have all heard the expression “Monkey see, Monkey do”. Analyzing individual primates at the Santa Ana Zoo was quite an experience because when I use to hear monkeys I use to only picture one certain appearance and that was a brown monkey with a light brown face, and a long tail. Moneys are not just monkeys, humans aren’t just humans, and apes aren’t just apes they are all primates which is a mammal that has certain characteristics such as: flexible fingers and toes, opposable thumbs, flatter face than other mammals, have eyes that face forward and spaced close together, large and complex cerebrum, and they are also social
The purpose of this paper is to analyze the economic situation of the company Macedonian Shipping and give a recommendation whether the company should use the motor vessel Tashtego as a freight tender beween Dar-es-Salaam and Zanzibar in East Africa or as a tapioca ship between Balik Papan and Singapore in the East Indies.
An injury to the ACL is classified as a sprain. A sprain is a joint injury that causes a stretch or a tear in a ligament. Sprains are graded I, II, or III depending on how severe the injury is. A grade I sprain will have pain with minimal damage to the ligaments. A grade II sprain is going to have more ligament damage and mild looseness of the joint. Finally, in a grade III sprain, the ligament is completely torn and the joint is very loose or unstable. A grade III sprain, simply called an ACL tear, is most often a sports-related injury. Still, The ACL can be torn in other instances such as during rough play, vehicular collisions, falls, and work –related injuries. According to a study performed by Jonathan Cluett, M.D., about 80% of sports-related ACL tears are “non-contact” injuries. This means that the injury does not result from any contact with another athlete. A rupture to the ACL is the result of the ligament within the knee being overstretched. This is usually caused by a “plant-pivot” mechanism (a stop and twist motion) of the knee, or a blunt force to the front of the knee. Other factors include quick changes of motion, twisting or torquing, or landing from a jump. Hyperextension is most
Tommy John surgery, or more well known as ulnar collateral ligament reconstruction, is a surgery in which a ligament in the medial elbow is replaced with a ligament from elsewhere in the body. This replacement ligament is usually taken from the forearm, hamstring, or foot of the patient. This ligament is needed for everyday things such as twisting a doorknob. This injury is usually seen in professional baseball pitchers because of the daily repetitive throwing and because of violent motions from throwing a baseball. RA Dickey was born without a UCL and pitches in the majors. Doctors still do not know how he can do this because you should not be able to do anything this way.

In this passage from Salvage the Bones, Jesmyn Ward uses Esch’s and Manny’s encounter to reveal the way Esch feels towards Manny, signifying a one-sided emotional attachment. The selected passage reveals one of the main characters, Esch, as being taken advantage of due to her feelings for Manny. Manny and Esch have been intimate before, however, the two’s views on the encounters were dissimilar. Esch talks about her past encounters and compares them to Manny when she says, “The girly heart that, before Manny, I’d let boys have because they wanted it, and not because I wanted to give it” (Ward). When the author uses this to describe the way Esch feels about Manny and how she sees him differently than the rest of her past. Although Ward provides a detailed description of the emotional attachment Esch feels towards Manny, there is a repudiation of feelings presented as well such as when Esch claims that Manny wouldn’t touch her, “but his hips would” (Ward).
Imagine that there is a disease that is terrible and causes trouble for you every day, there is no cure, there is only the dragging on of day after day. This is Tay Sachs Disease, it is a disease that is lifelong, that is, unless it kills you early on in life. This disease has lots of symptoms. These symptoms are a result of how the disease affects the brain and its functionality. This disease is an inherited disease, and is known as a serious genetic disease.(“Health and Wellness Resource center and Alternative Health Module”). This disease is a autosomally recessive disease that is caused by a defect in the HEXA gene which provides instructions for making part of an enzyme called beta hexosaminidase A, which is critical in the brain
The tearing oh the posterior cruciate ligament is another sports related knee injury, though less common than the ACL. This injury can occur when the knee is forcefully twisted or hyper-extended, but other ligaments are usually injured or torn, before the posterior cruciate ligament (PCL) is torn in these injuries. The most common way for the PCL alone to be injured is from a direct blow to the front of the knee while the knee is bent. If the tibia moves too far back the PCL can rupture. This is a common cause of injury to the PCL during an automobile accident. As the automobile strikes another and stops suddenly, the front passenger or driver slides forward. The bent knee hits the dashboard just below the kneecap. This forces the tibia backward on the femur tearing the PCL. The same force can occur during a fall on the bent knee, where the force of the fall on the tibia pushes it back
The Anterior Cruciate Ligament “…is a primary restraint to anterior drawer of the tibia” (Halewood & Amis, 2015, p. 2790) which means that it keeps the tibia from moving too far forward. Providing controlled extension, it is also a primary player in knee stability (Kisner & Colby, 2012, p. 803). It
The injuries of Med. Collateral Lig. are divided into grades: grade one tears that involve a few MCL fibers with localized tenderness. Grade two tears involve disruption of more MCL fibers with generalized tenderness . Grade three tears are complete tears resulted in laxity of the medial joint to valgus stress. (FIG.14) ( 69
Clinical examination may be difficult in acute injury and is inconclusive in cases with injuries of multiple ligaments/menisci. ( 73 ) Injuries to the knee resulting from acute trauma can occasionally limit full extension of the knee, due to swelling, and muscle spasm. ( 87 )

In the past decade, network television has been bombarded by crime shows attempting to make their mark on viewers. All of these programs—CSI, Lie to Me, Numb3rs, Law & Order—have the same general set up of a male lead with a hot-head who is complemented by his team of FBI agents. As a loyal viewer and fan of Bones, I often wonder what makes it stay afloat with so many shows out there like it. Could it be that Bones isn’t like any of the other crime shows? Through its crimes and unsolved murders, Bones helps its viewers make sense of the disastrous world around them. The world we live in is full of danger and unsolved crime, but after watching Dr. Brennan, her team of “squints” and Agent Booth solve even the most bizarre murders, the
2015). The Unconventional Fracture Model (UFM), developed by Cipolla et al. (2010), considers the effect of natural fractures, stress distribution, and influence of the mechanical properties of fracture morphology (Cipolla et al. 2010). The UFM model can simulate the propagation of asymmetric fracture networks accounting for fluid flow in the fracture network and elastic deformation of the fractures. The initial assumptions and governing equations (fluid flow in the fracture network, mass conservation and fracture deformation) are similar to the conventional P3D model (Weng 2015).
