ABSTRACT This paper examines long-term (more than four solar cycles) temporal and spatial fluctuations in the rotation by investigating radio-emission escapes from various layers of atmosphere during years 1967–2010. The flux modulation approach can also be used to investigate variations rotation, which is a contentious topic physics. study makes use time-series radio data at frequencies (245–1...

introduction: langerhans cell histiocytosis (lch) is a rare disease characterized by clonal prolifera-tion of histiocytosis in different tissues. permanent consequences (pc) described among subjects with langerhans cell histiocytosis (lch).in this study we report the prevalence of permanent sequel among long – term survivors of lch in our center. methods: we had 30 cases of lch from 1989 – 2001...

The purpose of this study was to examine the physiological characteristics of an elite centenarian cyclist who, at 101 yr old, established the 1-h cycling record for individuals ≥100 yr old (24.25 km) and to determine the physiological factors associated with his performance improvement 2 yr later at 103 yr old (26.92 km; +11%). Before each record, he performed an incremental test on a cycling ...

Abstract We present the SuperWASP light curve of a 10th magnitude A7V star containing single, well-defined U-shaped transit-like event lasting around 11 days with depth 1.1%. The is otherwise non-variable throughout 8 yr duration observations. If modeled as an exoplanet transit, it compatible 1.8 R J in ∼205 au orbit period ∼2200 yr.

A pollen record from Lago Condorito (41 45’S, 73 07’W) shows prominent vegetation and climate changes at millennial time-scales, superimposed on multimillennial trends in temperature and westerly activity in northwest Patagonia during the past 15 000 yr. The record shows that evergreen temperate rainforests have dominated the landscape over this interval, with floristic changes ranging from col...

BACKGROUND Chronic pain is common after thoracotomy with reported prevalence rates of 20-60%. The pain may be caused by damage to the intercostal nerves during surgery. Some studies have suggested that young age at the time of surgery reduces the risk of developing chronic pain. So far, no studies have examined if children and adolescents develop chronic pain after thoracotomy. METHODS Eighty...

OBJECTIVE The quality and radiation dose of different tube voltage sets for chest digital radiography (DR) were compared in a series of pediatric age groups. MATERIALS AND METHODS Forty-five hundred children aged 0-14 years (yr) were randomly divided into four groups according to the tube voltage protocols for chest DR: lower kilovoltage potential (kVp) (A), intermediate kVp (B), and higher k...
