The Figuera Lava, the oldest stratigraphic unit now recognized in northeastern Puerto Rico, and the overlying Fajardo Formation are redescribed and the name Figuera redefined and reinstated for formal use. Previously, lower Tertiary strata some distance from the type areas of the Figuera and Fajardo were correlated with the units by reconnaissance. Recent detailed mapping and paleontology now p...

We investigate an outcrop of 187 Ma lacustrine pillow basalts of the Talcott Formation exposed in Meriden, Connecticut, USA, focusing on coordinated analyses of one pillow lava to characterize the aqueous history of these basalts in the Hartford Basin. This work uses a suite of multidisciplinary measurements, including hyperspectral imaging, other spectroscopic techniques, and chemical and mine...

Studies along the Mid-Atlantic Ridge (MAR) and East Pacific Rise (EPR) show that seamount abundance is a strong function of spreading rate. At the MAR, small axial seamounts are a dominant morphologic feature of the inner valley floor, while at the EPR seamounts are rarely observed within the neovolcanic zone. The Gala¤pagos Spreading Center (GSC) provides an excellent location to test the infl...

The Kahnuj ophiolitic complex, a part of the Jazmurian ophiolitic belt, is located on the western boundary of the Jazmurian depression and is bounded by two major fault systems. There is a well-preserved, ophiolite pseudostratigraphy of early Cretaceous to early Palaeocene age and has a bearing on the Mesozoic development of southeastern part of Iran and adjacent region. The Kahnuj ophiolitic c...

Study reported a pillow with a uniform height was not suitable for sleeping in supine and lateral positions. The study aims to determine the pillow dimensions for fitting supine and lateral positions for Taiwanese. Ten females and ten males subjects with a mean age of 21.9 years (SD= 1.07 years) participated in the study. Body dimensions of head, neck and shoulder in crown and sagittal planes w...

OBJECTIVE To investigate the effect of different pillow heights on the slope of the cervicothoracic spine segments. METHODS A prospective analysis of data from 16 asymptomatic adults (aged 20 to 30 years) was carried out. Exclusion criteria were history of injury or accident to the cervicothoracic spine, cervicothoracic spine surgery, or treatment for neck symptoms. We used three different pi...

BACKGROUND Disorders of the cervical spine are often observed in patients with rheumatoid arthritis (RA). However, the best head position for RA patients with atlantoaxial subluxation in the perioperative period is unknown. This study investigated head position during general anesthesia for the patients with RA and proven atlantoaxial subluxation. METHODS During anesthesia of patients with RA...

The exposure of Mesozoic rocks in the Mangilu area, both as a result tectonic deformation form mélange, low-high degree metamorphism and deep-sea sediments (flysch, radiolarian cherts, sediment flow olistostrome), which formed subduction zone indicates complex accretionary rocks. purpose this study is to identify trace era. method used was field observation, including collection geological data...
