Breathing & Buoyancy Control: Stop, Breathe, Think, And
Breathing & Buoyancy control: Stop, Breathe, Think, and then Act For an introduction to this five part series see: House of Cards 'As a child I was fascinated by the way marine creatures just held their position in the water and the one creature that captivated my curiosity and inspired my direction more than any is the Nautilus. Hanging motionless in any depth of water and the inspiration for the design of the submarine with multiple air chambers within its shell to hold perfect buoyancy it is truly a grand master of the art of buoyancy. Buoyancy really is the ultimate Foundation skill in the repertoire of a diver, whether they are a beginner or an explorer. It is the base on which all other skills are laid. With good buoyancy a problem does not become an emergency it remains a problem to be solved calmly under control. The secret to mastery of buoyancy is control of breathing, which also gives many additional advantages to the skill set of a safe diver. Calming one's breathing can dissipate stress, give a sense of well being and control. Once the breathing is calmed, the heart rate will calm too and any situation can be thought through, processed and solved. Always ‘Stop, Breathe, Think and then Act.' Breath control is used in martial arts as a control of the flow of energy, in prenatal training and in child birth. At a simpler more every day level, just pausing to take several slow deep breaths can resolve physical or psychological stress in many scenarios found in daily life. -

Law of Hydrostatics‘’)
10 LAW OF HYDROSTATICS‘’) 10.1 INTRODUCTION When a fluid is at rest, there is no shear stress and the pressure at any point in the fluid is the same in all directions. The pressure is also the same across any longitudinal section parallel with the Earth’s surface; it varies only in the vertical direction, that is, from height to height. This phenomenon gives rise to hydrostatics, the subject title for this chapter. Following this introduction, this chapter addresses (once again) pressure principles, buoyancy effects (including Archimedes’ Law), and manometry principles. 10.2 PRESSURE PRINCIPLES Consider a differential element of fluid of height, dz, and uniform cross-section area, S. The pressure, P, is assumed to increase with height, z. The pressure at the bottom surface of the differential fluid element is P; at the top surface, it is P + dP. Thus, the net pressure difference, dP, on the element is acting downward. A force balance on this element in the vertical direction yields: downward pressure force - upward pressure force + gravity force = 0 (10.1) Fluid Flow for the Pmcticing Chemical Engineer. By J.

John Herrington Born in Chickasaw Nation, John Bennett Herrington is a retired United States Naval Aviator and former NASA astronaut. In 2002, Herrington became the first enrolled member of the Native American tribe to fly in space. This was abord the Space Shuttle Endeavor’s STS-113 mission. Tom Bee and Douglas Spotted Eagle Following a three-year lobbying effort by Ellen Bello, founder of the Native American Music Awards and the Native American Music Association, the Grammy award was first presented to Tom Bee and Douglass Spotted Eagle in 2001 as the producers of the compilation album Gathering of Nations Pow Wow. In 2011, the category Best Native American Music Album was eliminated along with thirty others and replaced. Native American works will now be eligible for the Best Regional Roots Music Album category. Susan La Flesche Picotte Born on the Omaha reservation in northeastern Nebraska on June 17th, 1865, Susan La Flesche Picotte was a Native American doctor and reformer in the late 19th century. She is widely acknowledged as the first Native American to earn a medical degree. She campaigned for public health and for the formal, legal allotment of land to members of the Omaha tribe. Before becoming a place to honor and celebrate the life and word of Picotte, the Susan La Flesche Picotte Center was once a hospital named after her, then a center that cared for the elderly. She lived till 1915. Stanley Crooks From 1992 to 2012, Stanley Crooks served as the first chairman of Shakopee Mdewakanton, America’s richest Native American tribe near Minneapolis, MN. -
DIVING DOWN DEEP TI-Nspire™ Lab Activity
*AP is a trademark owned by the College Board, which was not involved in the production of, and does not endorse, this product. DIVING DOWN DEEP TI-Nspire™ Lab Activity Background The Neutral Buoyancy Laboratory (NBL) is a deep pool located inside the NASA Sonny Carter Training Facility in Houston, Texas. The NBL is 61.6 m (202 ft) long, 31.1 m (102 ft) wide, and 12.2 m (40 ft) deep, which allows two different training activities to be performed simultaneously at either end of the pool. The NBL is large enough to hold full-sized models of International Space Station (ISS) modules, spacecraft (like the Orion Crew Multi-Purpose Crew Vehicle) and flight payloads. The NBL uses neutral buoyancy to train astronauts for spacewalks. Being in a neutrally buoyant state is similar to the feel of weightlessness in space. In a neutrally buoyant state, an object has an equal tendency to float as it does to sink. Objects in the NBL, including humans, are made neutrally buoyant using a combination of weights and flotation devices. In such a state, even a heavy object can be easily manipulated, as is the case in the microgravity of space. When training in the NBL, astronauts wear pressurized Extra-vehicular Mobility Unit (EMU) suits, the same as those worn in space. Out of the water, these EMU suits weigh approximately 127 kg (280 lbs). During training, the EMU-suited astronauts are assisted by at least four professional support divers wearing regulation SCUBA gear.

Virginia 23681-0001 Neutral Buoyancy Test Evaluation of Hardware and Extravehicular Activity Procedures for On-Orbit Assembly of a 14 Meter Precision Reflector Walter L. Heard Jr. and Mark S. Lake Summary A procedure that enables astronauts in extravehicular activity (EVA) to perform efficient on-orbit assembly of large paraboloidal precision reflectors is presented. The procedure and associated hardware are verified in simulated 0g (neutral buoyancy) assembly tests of a 14 m diameter precision reflector mockup. The test article represents a precision reflector having a reflective surface which is segmented into 37 individual panels. The panels are supported on a doubly curved tetrahedral truss consisting of 315 struts. The entire truss and seven reflector panels were assembled in three hours and seven minutes by two pressure-suited test subjects. The average time to attach a panel was two minutes and three seconds. These efficient assembly times were achieved because all hardware and assembly procedures were designed to be compatible with EVA assembly capabilities. Introduction NASA is developing the technology to build precision reflector spacecraft for future Earth- observation missions. -

IAG09.B6.3.6 21 St CENTURY EXTRAVEHICULAR ACTIVITIES: SYNERGIZING PAST AND PRESENT TRAINING METHODS FOR FUTURE SPACEWALKING Si"CCESS Sandra K. Moore, Ph.D. United Space Alliance, LLC 600 Gelrlini, Houston TX; 77058-2783 ;USA sandra.k.moore@rasa. gov Matthew A. Gast United Space Alliance, LLC 600 Gelrlini, Houston TX, 77058-2783; USA lnatthew.gast-1 @nasa.gov Abstract Neil Armstrong's understated words, "That's one small step for man, one giant leap for mankind." were spoken from Tranquility Base forty years ago. Even today, those words resonate in the ears of millions, including many who had yet to be born when man first landed on the surface of the moon. By their very nature, and in the tnie spirit of exploration, extravehicular activities (EVAs) have generated much excitement throughout the history of manned spaceflight. From Ed White's first space walk in June of 1965, to the first steps on the moon in 1969, to the expected completion of the International Space Station (ISS), the ability to exist, live and work in the vacuum of space has stood as a beacon of what is possible. It was NASA's first spacewalk that taught engineers on the ground the valuable lesson that successful spacewalking requires a unique set of learned skills. That lesson sparked extensive efforts to develop and define the training requirements necessary to ensure success. As focus shifted from orbital activities to lunar surface activities, the required skill-set and subsequently the training methods, changed. The requirements duly changed again when NASA left the moon for the last time in 1972 and have continued to evolve through the Skylab, Space Shuttle ; and ISS eras. -
