BACKGROUND Circadian variation of joint stiffness (morning stiffness) and its impact on functional ability are widely recognised in rheumatoid arthritis. Subsequent within-day variation of walking ability is important due to the increased availability of instrumented gait analysis. This study aimed to quantify diurnal variation of gait in patients with rheumatoid arthritis, and explore associat...

Abstract Recent research has found anthropogenic forcing to also affect day-to-day variability of temperatures. For many people, the climate is not only becoming hotter but more volatile. Based on new climate-economy literature, I explore historical impact temperature variation mortality in United States over a 35-year period. find that an extra <mml:math xmlns:mml="http...

Essential oil molecules released from fresh leaves of sweet basil (Ocimum basilicum L.) were collected in Tenax traps and analysed using a TD-GC/MS. During daytime from 09.00 to 17.00, there were no differences in the content and composition of total essential oils, however the percentage of eugenol increased slightly. Significant differences were found in both the total content and composition...

The frequency of use of commonly performed obstetric procedures to assist in vaginal delivery has been shown to vary according to characteristics of both the patient and provider, independently of clinical indications for intervention. This variation in procedure use according to “non-medical” factors is worthy of attention, as it raises the spectre of unnecessary intervention that increases th...

Transport systems are inherently uncertain, posing a challenge to network modellers and planners. Newer models (probabilistic user equilibrium, strategic user equilibrium) attempt to capture this uncertainty by explicitly acknowledging day-to-day randomness in the network, and solve for strategic equilibrium conditions based on the concept of travellers optimizing their expected performance. St...
