âBeing hospitalized can be a scary time for people, and they may not always understand whatâs going on,â says William Atchley, a hospitalist in Norfolk, Virginia. Hospitalists aim to reduce the confusion of a hospital stay and guide patients through their treatment. Although they are physicians, hospitalists donât have an office practice. Instead, they serve as the single point of contact for a patient moving through the hospital, from admittance to dischargeâand beyond. What they do
The mid ocean ridge systems are the largest geological features on the planet. The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87Â°N-about 333km south of the North Pole-to subantarctic Bourvet island at 54Â°S.ost of the ridge system is under water but forms land as a set of volcanic islands of varying size that run the length of the Atlantic Ocean. These islands are: 1  Jan Mayen (Norway). 2  Iceland. 3  Azores (Portugal). 4  St Paulâs rock (Brazil). 5  Ascension Island (UK).
The Mid-Atlantic Ridge is composed of discrete spreading segments that are tens of kilometers long, and offset by transform faults and nontransform offsets. The axis of the Mid-Atlantic Ridge is marked by a major rift valley 1 to 1.5 kilometers deep, a central floor 4 to 15 kilometers across, and ranges of crestal mountains on each side of the valley separated by 20 to 40 kilometers. The median valley walls are composed of large faults that move the crust upwards to form the crestal mountains.
