Periodic accelerations in the decreasing resistance of adult Drosophila (pure line) to the penetration of alcohol vapor are specifically paralleled by changes in the rate of accumulation of deaths in a life duration experiment with the same line. The necessary interpretation is that there occur under constant conditions periodic fluctuations in the speed of general metabolic events, marking the...

Self-consistent stellar models including all effects of atomic diffusion and radiative accelerations as well as mass loss are evolved from the pre main sequence for stars of 1.35-1.5 M⊙ at solar metallicity (Z=0.02). A mass loss rate similar to the solar mass loss rate is sufficient to reproduce observations of the star τUMa. We discuss the effect of mass loss on the iron convection zone that n...

225 words] 33 34 Recent studies have demonstrated that human quiet standing is a multi-joint movement, 35 whereby the central nervous system (CNS) is required to deal with dynamic interactions 36 among the joints to achieve optimal motor performance. The purpose of this study was to 37 investigate how the CNS deals with such inter-joint interaction during quiet standing by 38 examining the rela...

Prediction models were developed based on keyboard and mouse use in combination with individual factors that could be used to predict median upper extremity muscle activities, postures, velocities, and accelerations experienced during computer use. In the laboratory, 25 participants performed five simulated computer trials with different amounts of keyboard and mouse use ranging from a highly k...

The purpose of this study was to examine how inducing fatigue of the 1) lumbar erector spinae and 2) cervical erector spinae (CES) muscles affected the ability to maintain head stability during walking. Triaxial accelerometers were attached to the head, upper trunk, and lower trunk to measure accelerations in the vertical, anterior-posterior, and mediolateral directions during walking. Using th...

in this paper, vehicle’s fuel consumption and exhaust emissions are investigated in different driving conditions based on driving segments clustering. driving data collection is performed using global positioning systems in real traffic conditions. the driving data is clustered into five groups using k-means clustering technique. vehicle’s fuel consumption and exhaust emissions (i.e. hc, nox a...

Recent studies have demonstrated that human quiet standing is a multijoint movement, whereby the central nervous system (CNS) is required to deal with dynamic interactions among the joints to achieve optimal motor performance. The purpose of this study was to investigate how the CNS deals with such interjoint interaction during quiet standing by examining the relationship between the kinetics (...

The turning flight of six microchiropteran bat species is described. The bats' abilities to turn tightly were determined by their abilities to fly slowly and to generate high lateral accelerations. Rhinolophus ferrumequinum developed high lateral accelerations by flapping its banked wings while flying at very low speed. Plecotus auritus turned at relatively low speed and at low lateral accelera...
