BACKGROUND Linear and angular measurements such as A point, nasion, B point (ANB) angle and Wits appraisal index are not accurate enough to evaluate sagittal relationship of the jaws. The aim of this study was to evaluate and compare the range of μ and β angles in 6-17-year-old children of Isfahan, having normal occlusion. MATERIALS AND METHODS This was an analytical descriptive study. For th...

Vortex shedding behind an elastically mounted circular cylinder in the presence of group focused waves propagating upstream was investigated using a classical approach (time series and FFT) nonclassical (complex 2D Morlet wavelets). Wavelet analysis emerged as novel solution this regard. Our results include wave trains with different nonlinearities water depths derived from three types spectra ...

Abstract Surface gravity waves are formed by kinetic energy transfer across the air‐sea interface. Significant improvements have been made in understanding influence of wind on input waves. However, impact gustiness remains underexplored, and little is known about mechanisms through which gusts alter wavy surface. In this study, we utilize three‐months observational data collected during 2010 I...

Proline is synthesized from glutamic acid by way of the intermediate glutamic -y-semialdehyde, as in the following equation: glutamic acid + glutamic 'y-semialdehyde -* proline. In Escherichia coli W, the first reaction is subject to endproduct inhibition by proline (A. Baich and D. J. Pierson, Biochim. Biophys. Acta 104:397, 1965). This reaction is also inhibited by low, although higher than b...

The lowest-order nonlocal small slope approximation (NLSSA) reflection coefficient is derived, and numerical results are presented for one-dimensional (1-D) surfaces, satisfying the Dirichlet boundary condition. Reduction to the perturbation expression occurs in the small height limit, and the first term of the reflection coefficient gives the Kirchhoff approximation (KA) result. Numerical resu...

The paper investigates a representational model for narratives, aiming to facilitate the acquisition of the systematic core of stories concerning legal cases, i.e. the set of causal and temporal relationships that govern the world in which the narrated scenario takes place. At the discourse level, we consider narratives as sequences of messages collected in an observation, including description...

The purpose of the present investigation was to examine the relationship between multidimensional perfectionism and athlete burnout. The target population of research consisted of 168 elite handball players who participate in National Junior Championships. 123 athletes were selected randomly as the sample. We used a multi-section inventory to collect data, contained measures of multidimensional...
