in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...

The end of a thermal inflation era, driven by the rolling of a flaton field coupled to the curvaton, cause a huge increment in the curvaton mass and decay rate while the curvaton is still frozen. It is shown that, if this increment is enough for the curvaton to immediately decay, low scale inflation with Hubble parameter H∗ ∼ 10 GeV is achieved for more natural values of the flaton-curvaton cou...

OBJECTIVES To investigate to what extent bone mass accrual is determined by physical activity and changes in lean, fat, and total body mass during growth. METHODS Twenty six physically active and 16 age matched control boys were followed up for three years. All subjects were prepubertal at the start of the survey (mean (SEM) age 9.4 (0.3) years). The weekly physical activity of the active boy...
