The Tinguiririca Fauna of the Andean Main Range of central Chile is remarkable for its abundant and diverse archaeohyracids. This study recognizes four relatively large-bodied species from the Tinguiririca Fauna, two of which are new. Together with two previously described small-bodied forms, the total of six species makes the archaeohyracid assemblage from Tinguiririca the most diverse known, ...

It is substantiated that particular features of pragmatics are teachable, and instruction is both necessary and effective. Determining what kind of intervention is most effectual for facilitating learners’ pragmatic development has been a central issue for researchers. To respond to the inconclusive findings in intervention studies and to extend the instructional studies in L2 pragmatics to les...

A 44-year-old man consulted an internist because of abnormalities in an upper gastrointestinal series. It showed an elevated lesion with central depression in the greater curvature of the middle part of the stomach. Upper gastrointestinal endoscopy showed an elevated lesion with central depression, bridging hold, and no abnormalities of the gastric mucosa in the greater curvature of the middle ...

Objectives: The aims of this study were to test whether lightening of the overexposed radiographs improve determination of endodontic files length and whether lightened radiographs are comparable with ideally exposed radiographs. Material and Methods: Four dried human skull coated with soft tissue-equivalent wax used for exposing radiographs of the upper molars. First, the endodontic file was p...

The analysis of record-breaking events is interest in fields such as climatology, hydrology or anthropology. In connection with the record occurrence, we propose three distribution-free statistics for changepoint detection problem. They are CUSUM-type based on upper and/or lower indicators observed a series. Using version functional central limit theorem, show that asymptotically Kolmogorov dis...

403 A COMBINATION OF STRUCTURAL AND NEUROMUSCULAR CONTROL FACTORS CONTRIBUTE TO THE PATHOGENESIS OF CHILDHOOD OBSTRUCTIVE SLEEP APNEA syndrome (OSAS).1-6 However, the cause of the neuromuscular abnormalities is not well understood. Previous work has shown that, compared to normal controls, children with OSAS have selectively elevated arousal thresholds to respiratory stimuli, such as mechanical...
