BackgroundHuman growth is susceptible to damage from insults, particularly during periods of rapid growth. Identifying those and the normative limits that are compatible with adequate development first key steps toward preventing impaired growth.ObjectiveThis study aimed construct international fetal velocity increment conditional standards 14 40 weeks’ gestation based on same cohort contribute...

We describe planetesimal accretion calculations in the Kuiper Belt. Our evolution code simulates planetesimal growth in a single annulus and includes velocity evolution but not fragmentation. Test results match analytic solutions and duplicate previous simulations at 1 AU. In the Kuiper Belt, simulations without velocity evolution produce a single runaway body with a radius ri ∼> 1000 km on a t...

The drift velocity of an auroral arc is compared with the component of F-region plasma velocity in the same direction for ten cases where the arc is seen to move steadily equatorward for several minutes without any major change in appearance or orientation. In most cases the two velocities are close, but on two occasions the drift velocity of the arc is much higher than the plasma velocity. Fro...

Asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.From these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. Instability condition is obtained and g...

We find that a steady state bar induces transient features at low velocities in the solar neighborhood velocity distribution due to the initial response of the disk, following the growth of the bar. We associate these velocity streams with two quasi-periodic orbital families, librating around the stable x1(1) and x1(2) orbits near the bar’s outer Lindblad resonance (OLR). In a reference frame m...

Objective: To evaluate the stature growth rate (GR) and the weight gain of prepubertal asthmatic children. Method: A retrospective cohort study evaluating medical records of 85 children diagnosed with asthma, aged less than 9 years, of both sexes, with at least one year of follow-up in the allergy outpatient clinic. The data on the disease, weights and heights were collected through a standa...

We investigate the complex spatiotemporal dynamics in avalanche driven surface growth by means of scaling theory. We study local activity statistics, avalanche kinetics, and temporal correlations in the global interface velocity, obtaining different scaling relationships among the involved critical exponents depending on how far from or close to a critical point the system is. Our scaling argum...

In this paper, we study the 3D axisymmetric Navier-Stokes Equations with swirl. We prove the global regularity of the 3D Navier-Stokes equations for a family of large anisotropic initial data. Moreover, we obtain a global bound of the solution in terms of its initial data in some Lp norm. Our results also reveal some interesting dynamic growth behavior of the solution due to the interaction bet...

A limited number of reports of estrogen levels in prepubertal and early pubertal boys have been published because previous estrogen assays have lacked adequate sensitivity to quantitate circulating estrogen concentrations. Development of a new ultrasensitive assay has permitted measurement of estrogen levels in 23 normally growing boys progressing through puberty. Concentrations were measured a...
