In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability.
We dispel the myth that, at least in the case of Asian elephants, they can move at 25 mph. We were surprised to discover hints that elephants "bounce", fitting the modern biomechanical definition of running.
We have not proven this, but it seems likely. The basic principles governing locomotion in animals larger than a horse remain poorly understood. Elephants are the best choice to begin studying as they are the largest land animals.
Besides, elephants are strange and fascinating animals that are a joy to work with. Why should the public care? Asian elephants are endangered; we should learn from them while healthy, active populations are still available to study.
The general principles that we can learn from large animals like elephants apply even to humans, as these principles are about factors such as size, speed, strength, and stability.
Also, the public should know about the way biomechanists define running today: How did we do it? The elephants were motivated to move fast with food rewards, comfort, competition, cheering, playful chasing, other positive reinforcement, etc.
One elephant, Pop, was so excited by the experiments that she had to be held back from running down the course, and broke free at full speed twice once making one of our speed records.
The scope of the project was broad: Thus we feel that we have found a reasonably close estimate of the maximum speed of Asian elephants, although it is likely some few can move slightly faster.
Force platforms are being designed to definitively solve the running question. We also hope to work with African elephants as some have said they are faster than Asian elephants.
Computer models can be used to test what features limit elephant speed and gait. Later, research on other large animals such as hippos, rhinos, and giraffes is needed. We provided the first well-documented study of the locomotion of elephants, the largest land animals.
This subject has been surrounded by confusion and misinformation. The confusion about elephant locomotion extends back to the late s, involving famous researchers such as Eadweard Muybridge who was among the first to use cinematography, and so won a bet for Leland Stanford that all four legs of a horse leave the ground during a trot and continuing to the present, when studies of animal locomotion cite widely different maximum speeds and gaits for elephants.
The myth that all elephants can move at 25 mph and still walk! We still hear assurances from people familiar with fast African elephants that they can move 25 mph, but speeds are difficult to measure accurately. For comparison, a typical high-school sprinter at 20 mph, or a champion Olympian m dash at 25 mph average speed, could outrun an Asian elephant without difficulty.Research Methods in Physical Activity, Seventh Edition, instills in students the confidence to devise, collect, analyze, and present their research in a competent manner by systematically guiding them through the research process.
It is an essential text for all emerging researchers in physical activity. The Kinetics is one of the most popular assignments among students' documents. If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples.
