BACKGROUND Baseball pitchers need trunk strength to maximize performance. The Pilates method of exercise is gaining popularity throughout the country as a fitness and rehabilitation method of exercise. However, very few studies exist that examine the effects of the Pilates method of exercise on trunk strength or performance. OBJECTIVES Using a single subject, multiple baseline across subjects...
For the past twenty years, the primary double star observational technique utilized at the US Naval Observatory (USNO) has been speckle interferometry. Our two speckle cameras have been used on a variety of telescopes: our 26-inch in Washington, the Naval Observatory Flagstaff Station (NOFS) 61-inch, the McDonald Observatory 82-inch, the Mt. Wilson Observatory 100-inch and the twin 4 meter tele...
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced, and thereby the particle measurements improved, by emitting a positive ion beam. This method has successfully been applied on several other spac...
We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC1) were located in the same local time sector: 7 August 2004, 18:00–24:00 UT, during a disturbed southward/northward IMF interval, and 14 August 2004, 21:00–24:00 UT, when the IMF was stably northward. Cluster observed dipolarization as well as fast flows during both intervals, but this w...
