OBJECTIVE To determine the correlations among various dyspnea scales, spirometric data, exercise tolerance data, and the Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) index in patients with COPD. METHODS Between March of 2008 and July of 2009, 79 patients with COPD were recruited, and 50 of those patients were included in the study. After being regularly treated w...

Blunted perception of dyspnoea under resistive loading has been observed in patients with a history of near-fatal asthma (NFA). The perception of dyspnoea at rest and at the end point of various exercises was assessed in such patients. Respiratory function and exercise capacity (6-min walking distance, incremental cycloergometry and inspiratory threshold loading) were assessed in seven NFA and ...

A total of 24 subjects with diagnosis of spina bifida, 24 subjects (females, n= 12), ages 17 to 72 years, participated in a one-time arm ergometry exercise stress test. The aim of this study was to investigate the construct and concurrent validity of two rating of perceived exertion scales, the Borg 6-20 Scale and a newly designed WHEEL Scale in adolescents and adults with spina bifida. The res...

We develop singular Weyl–Titchmarsh–Kodaira theory for Jacobi operators. In particular, we establish existence of a spectral transformation as well as local Borg–Marchenko and Hochstadt–Liebermann type uniqueness results.

Introduction Algorithm portfolio methods (Huberman, Lukose, and Hogg 1997) use information about solvers and problem instances to allocate computational resources among multiple solvers, attempting to maximize the time spent on those well suited to each instance. Portfolio methods such as SATzilla (Xu et al. 2008) have proved increasingly effective in satisfiability. An algorithm portfolio must...

BACKGROUND Airway function, as assessed by standard spirometry, and the intensity of dyspnea reported by asthmatic patients correlate poorly. OBJECTIVE This study tests the following two hypotheses: (1) that measures of the tendency of a patient to somatize will reduce the variation in the report of dyspnea not explained by airway function; and (2) that plethysmography is a better tool with w...

The aim of the present study was to establish the differences in dyspnoea perception between children with undiagnosed and diagnosed asthma. A cross-sectional community-based study was performed, which included a parental questionnaire on the child's respiratory health and testing of airway reversibility and bronchial hyperresponsiveness (BHR). "Diagnosed asthma" was defined by a physician's di...

The study of English language teachers’ cognitions and its relationship to teachers’ classroom practices have recently been the focus of language teaching and teacher education (Borg, 2006 & 2010). However, rarely have the studies delved into teachers’ knowledge about grammar (reviewed by Borg, 2001) or investigated the relationships between teachers’ knowledge about grammar and teachers’ actio...
