buckle folds are common traps for hydrocarbon in several contractional provinces. buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. an important parameter affecting buckle folding of a competent zone above a mobile decol...

Tension analysis along the retinal surface demonstrates the advantage of meridional buckles over limbal-parallel buckles. A cylindrical sponge generates tensional forces in the retina along the long axis of the buckle and perpendicular to it. The tension perpendicular to the sponge is positive, and the retina and retinal pigment epithelium stretch in that direction. The tension along the long a...

Purpose: To describe the spectral-domain optical coherence tomography features of chorioretinal folds of various etiology. Materials and methods: Cross-sectional observational case series of consecutive patients with chorioretinal folds. All patients underwent enhanced depth imaging optical coherence tomography over a two-month study period. Clinical variables and imaging features including sub...

We investigate the collapse of a lipid-coated nanobubble and subsequent formation of a lipid vesicle by coarse grained molecular dynamics simulations. A spherical nanobubble coated with a phospholipid monolayer in water is a model of an aqueous dispersion of phospholipids under negative pressure during sonication. When subjected to a positive pressure, the bubble shape deforms into an irregular...

When a polymer film that is weakly attached to a rigid substrate is exposed to solvent, swelling-induced compressive stress nucleates buckle delamination of the film from the substrate. Surprisingly, the buckles do not have a sinusoidal profile, instead, the film near the delamination buckles slides toward the buckles causing growth of sharp folds of high aspect ratio. These folds do not result...

The geometry of mesoscopic single and multiple layer folds in rhyolitic obsidian ̄ows is investigated. Folds are composed of obsidian embedded in a matrix of pumice. Folds form by buckling processes as indicated by discontinuous deformation between obsidian and pumice layers and by the geometries of wavetrains. Buckling occurs through a continuum of styles controlled largely by the thickness ra...

Folds on the surfaces of mafic lavas are among most readily recognized geological structures and used as first-order criteria for identifying ancient Earth other planetary bodies. However, presence surface-folds surface silicic is contested in this study we challenge widely accepted interpretation that lava contain folds using examples from western United States Sardinia, Italy. We interpret ri...

AIM The aim of the paper was to present the efficacy and indications for application of conventional surgical treatment of retinal detachment by using external implants, that is,application of encircling band and buckle. MATERIAL AND METHOD This study comprised patients from the University Eye Clinic in Skopje. A total of 33 patients were diagnosed and surgically treated in the period between...

We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares connected by small ligaments. Our combined analytical, experimental and numerical results indicate that under uniaxial tension the ligaments buckle out of plane, inducing the formation of 3D patterns whose morphology is controlled by the load direct...
