Description
Bioscience High School, a small magnet high school located in Downtown Phoenix and a STEAM (Science, Technology, Engineering, Arts, Math) focused school, has been pushing to establish a computer science curriculum for all of their students from freshman to senior year. The school's Mision (Mission and Vision) is to: "..provide a rigorous, collaborative, and relevant academic program emphasizing an innovative, problem-based curriculum that develops literacy in the sciences, mathematics, and the arts, thus cultivating critical thinkers, creative problem-solvers, and compassionate citizens, who are able to thrive in our increasingly complex and technological communities." Computational thinking is an important part in developing a future problem solver Bioscience High School is looking to produce. Bioscience High School is unique in the fact that every student has a computer available for him or her to use. Therefore, it makes complete sense for the school to add computer science to their curriculum because one of the school's goals is to be able to utilize their resources to their full potential. However, the school's attempt at computer science integration falls short due to the lack of expertise amongst the math and science teachers. The lack of training and support has postponed the development of the program and they are desperately in need of someone with expertise in the field to help reboot the program. As a result, I've decided to create a course that is focused on teaching students the concepts of computational thinking and its application through Scratch and Arduino programming.

Description
Ruptures in the anterior cruciate ligament are a prevalent injury, particularly in young athletes. This injury is frequently treated with surgical repair utilizing autologous tissue, cadaver allografts or synthetic grafts. However there is no definitive answer on which is the best graft option. This review aims to compare clinical results of patellar tendon autograft (PT), hamstring autograft (HT), cadaver allograft and LARS synthetic ligament in ACL reconstruction. The ASU library was systematically searched for comparison studies or meta-analyses that compared or described ACL reconstruction graft options. The results of the studies were analyzed according to re-tear rate, return to pre-injury level of activity, KT-1000 laxity scores, post-operative muscle strength, International Knee Documentation Committee Score (IKDC), Lysholm score, Lachman test and donor site morbidity. Allografts showed the highest re-tear rate and increase in laxity when compared with the PT autograft and HT autograft. PT autograft provided the most stability according to the KT-1000 results. Knee extensor muscle strength was not graft dependent, but knee flexor strength decreased significantly in HT autograft patients. All grafts showed comparable results for IKDC, Lysholm scores and Lachman tests. There was increased anterior knee pain in PT autograft patients however this did not seem to have an affect on the stability or durability of the graft. The PT autograft is the best choice for individuals undergoing ACL reconstruction on the basis of lower re-tear rates and greater joint stability.

Description
Electromyography (EMG) and Electroencephalography (EEG) are techniques used to detect electrical activity produced by the human body. EMG detects electrical activity in the skeletal muscles, while EEG detects electrical activity from the scalp. The purpose of this study is to capture different types of EMG and EEG signals and to determine if the signals can be distinguished between each other and processed into output signals to trigger events in prosthetics. Results from the study suggest that the PSD estimates can be used to compare signals that have significant differences such as the wrist, scalp, and fingers, but it cannot fully distinguish between signals that are closely related, such as two different fingers. The signals that were identified were able to be translated into the physical output simulated on the Arduino circuit.

Description
Training the bench press exercise on a traditional flat bench does not induce a level of instability as seen in sport movements and activities of daily living. Because of this, many new types of equipment have been created in an attempt to induce instability, such as the COR Bench. 15 males and 7 females between the ages of 18 and 30 were recruited for the present study, which tested two forms of instability: using one dumbbell rather than two, and lifting on the COR bench compared to a flat bench. Thusly, EMG was used to measure muscle activity in four separate conditions of unilateral bench press movements: on a flat bench with one dumbbell, on a flat bench with two dumbbells, on the COR Bench with one dumbbell, and on the COR Bench with two dumbbells. Results indicated that lifting with one dumbbell compared to two dumbbells on the flat bench significantly increased muscle activity across all four muscles being analyzed (pectoralis major, p = .005; middle trapezius, p = .008; external obliques, p = .004; and internal obliques, p = .003), but lifting with one dumbbell compared to two dumbbells on the COR Bench only significantly increased muscle activity in the middle trapezius (p = .001), external obliques(p = . 032), and internal obliques (p = .001). The only muscle to exhibit a significant increase in muscle activity when going from one dumbbell on the flat bench to one dumbbell on the COR Bench was the middle trapezius (p = .010). These results imply that the COR Bench itself does not increase muscle activity as much as switching from two dumbbells to one dumbbell, regardless of the bench being used.

Description
The objective of this project was to complete an in-depth design study for the creation of a prophylactic knee brace. Background literature research analysis demonstrated that soft tissue injuries of the knee were the most prominent injuries related to the knee joint. The literature exhibited that the leading injury of the knee joint consisted of ACL lesions and meniscal tears. Utilizing the information obtained, it was determined that the objective of the knee brace was to emphasize prophylaxis of soft tissue injuries. As such, further analysis was performed in order to analyze injury mechanisms and knee joint biomechanics that would be relevant in injury prevention. An epidemiological review was also conducted regarding current braces that existed in the market today. These results were accounted for when formulating a novel design for the prophylactic device. The key feature of the brace is the implementation of shear-thickening fluid, a non-Newtonian fluid that is able to exhibit fluid-like properties at rest and solid-like properties when impacted by an outside force. This unique property is ideal for a knee brace for its enhanced adaptability and protective effects. A three dimensional digital prototype was designed in a SolidWorks software as the final result. Future endeavors consist of developing a physical prototype and conducting stress and strain analysis of the device in addition to testing its efficacy in human trials. After completion of testing and necessary revisions the goal will be to patent the technology and commercialize the brace into a device available on the public market.
