purpose: to evaluate the effect of childhood corneal opacity on the anteroposterior length of the globe in adulthood. methods: twenty-three patients with significant unilateral corneal opacity which had developed before the age of 6 years and the normal fellow eyes (controls) were evaluated. a comprehensive ocular examination including measurement of anterioposterior length and anterior chamber...

In this work, we show that the eigenvalues of the problem  (∆2 + V (x) + λ)u(x) = 0 x ∈ Ω u(x) = ∆u(x) = 0 x ∈ ∂Ω are generically simple in the set of C4 regular regions of Rn, n ≥ 2. In fact, we prove that there exists a residual set of regions C4 diffeomorphic to a given Ω such that all the eigenvalues for a supported plate equation are simple.

To explore the role of olivine grain size and crystal preferred orientation (CPO), on evolution microstructure mechanical behavior upper mantle rocks up to large strains, we performed axial extension experiments at 1200 °C, 300 MPa confining pressure, constant displacement rate leading strain rates ~10?5 s?1 three natural peridotites: a fine-grained mylonitic harzburgite with weak CPO two coars...

With the increasing complexity of photo-realistic scenes, the question of building and placing objects in three-dimensional scenes is becoming ever more di cult. While the question of placement of rigid objects has captured the attention of researchers in the past, this work presents an intuitive and interactive scheme to properly place deformable objects with the aid of free-form deformation t...

Carbon nanotubes (CNTs) exhibit a unique buckling behavior due to their slender tubular geometry and thin-walled circular cross section. This study aims analyze effect of nonlinear cross-sectional deformation on CNTs. To accomplish this, CNTs are modeled as beam structures, the analysis is conducted using Variational Asymptotic Method (VAM) geometrically exact theory, well finite element (FEA)....

this study deals with the applications of a trigonometric shear deformation theory considering the effect of the transverse shear deformation on the static flexural analysis of the soft core sandwich beams. the theory gives realistic variation of the transverse shear stress through the thickness, and satisfies the transverse shear stress free conditions at the top and bottom surfaces of the bea...
