We have performed the monitoring observations of flux density of Sagittarius A at short millimeter wavelengths (100 and 140 GHz bands) on seven years in the period from 1996 to 2003 using the Nobeyama Millimeter Array (NMA). We found intra-day variation of Sgr A in March 2000 flare. The flux density at the peak of the flares increases 100–200% at 100 GHz and 200–400% at 140 GHz (∆S/S), respecti...

UNLABELLED • PREMISE OF THE STUDY Evolutionary changes in how flowering time responds to photoperiod cues have been instrumental in expanding the geographic range of agricultural production for many crop species. Locally adaptive natural variation in photoperiod response present in wild relatives of crop plants could be leveraged to further improve the present and future climatic ranges of cu...

Daily growth of the lower leg in a child receiving alternate day oral steroids for Crohn's disease was measured by knemometry. Growth occurred on days free of treatment. This may represent a direct observation of the growth sparing effect of alternate day steroid medication.

For an LTL (Less-than Truckload) carrier, the allocation of doors at a consolidation facility to outbound trailers assigned to various destinations, and to inbound trailers in the continuous stream arriving from various origins, has a significant impact on its operations, and on the nightly man-hours needed for consolidation. In the past literature door allocations to destinations of outbound t...

BACKGROUND To provide a detailed description of young adults' sedentary time and physical activity. METHODS 384 young women and 389 young men aged 22.1 ± 0.6 years, all participants in the 22 year old follow-up of the Raine Study pregnancy cohort, wore Actigraph GT3X+ monitors on the hip for 24 h/day over a one-week period for at least one 'valid' day (≥10 h of waking wear time). Each minute ...

BACKGROUND Variation in counts between subjects at a given speed or work rate are the most important source of error in physical activity (PA) measurements with accelerometers. The aim of this study was to explore how the use of individual accelerometer cut points (ICPs) affected the analysis of PA field data. METHODS We performed a treadmill calibration protocol to determine cut points for m...

Data from the Oxford Record Linkage Study were analysed to determine the amount of work undertaken in day case surgery for 12 surgical conditions in five districts in the Oxford Region during the years 1976 to 1985. Record linkage was used to study readmission rates, comparing day surgery with inpatient care. The use of day surgery gradually increased in some conditions (eg, termination of preg...
