OBJECTIVE To reassess the inclination of lower incisors and evaluate possible associations with gender, age, symphyseal parameters, and skeletal pattern. MATERIALS AND METHODS Twelve hundred and seventy-two (605 females, 667 males) cephalograms of untreated subjects of a craniofacial growth study (age: 8-16 years) were evaluated. Correlations between the angulation of the lower incisors and a...

The objective of the present study was to investigate frontal morphological asymmetry in the mandibular molar region in terms of tooth axis and skeletal structures using vertical MPR sections in jaw deformity accompanied by facial asymmetry. Subjects consisted of 15 patients with jaw deformity accompanied by facial asymmetry aged 17.4 years to 37.8 years. There were four men and eleven women. B...

Direct numerical simulations are used to investigate the method of effusion cooling in a laminar Mach-2.67 boundary layer. Air is employed as mean-flow and coolant gas and is introduced into the boundary layer through two staggered or aligned rows of holes by means of a modeled blowing approach. First, the effects of streamwise inclined blowing with various inclination angles αc are investigate...

The article reviews some of the (fairly scattered) information available in the mathematical literature on the subject of angles in complex vector spaces. The following angles and their relations are considered: Euclidean, complex, and Hermitian angles, (Kasner’s) pseudo-angle, the Kähler angle (synonyms for the latter used in the literature are: angle of inclination, characteristic deviation, ...

In this paper, the pulsatile flow of blood through an inclined catheterized stenosed artery is analyzed. Perturbation method is used to solve the implicit system of partial differential equations with suitable boundary conditions. Various analytical expressions axial velocity, flow rate, wall shear stress and effective viscosity have been derived with the help of MATLAB for understanding the fl...

We propose a method for measuring the black hole charge by imaging a black hole shadow in a galactic center by future interferometers. Even when the black hole is uncharged, it is possible to confirm the charge neutrality by this method. We first derive the analytic formulae of the black hole shadow in an optically thin medium around a charged spinning black hole, and then investigate how conto...

This project involved a preliminary investigation of the periodic clustering of particles in narrow channels under thin film flow. Motivated by particle clustering in runoff after a storm, we constructed an experiment to observe particle clustering behavior. The particle size is comparable to channel width. The channel can be varied in width and angle of inclination. Flow rate can also be varie...
