The need of central vein cannulation has been increased since the case critical patients and underwent high-risk patients. Supraclavicular approach is an alternative to due fewer anatomical variance, good longitudinal view, better visualization needle during procedure, clear demarcation landmarks, larger target area, patient comfort, complications. This study presents ultrasound guided using su...

In this work we investigate an inverse geometry problem. Given a light source, a diffuse plane and a caustic image, how must a geometric object look like (transmissive or reflective) in oder to project the desired caustic onto the diffuse plane when lit by the light source? In order to construct the geometry we apply an analysis-by-synthesis approach, exploiting the GPU to accelerate caustic re...

Prevention has a main role in reducing the occurrence of corrosive ingestion especially in children, yet this goal is far from being reached in developing countries, where such injuries are largely unreported and their true prevalence simply cannot be extrapolated from random articles or personal experience. Because of the accidental nature of the ingestions, the case fatality rate for pediatri...

The consideration of binary lenses is crucial in the analysis of self-lensing in microlensing surveys. A binary event presents high magnification peaks when the source crosses the caustic curve. We compute the rates of caustic crossing events both for resolved sources, such as towards the galactic bulge, and for unresolved sources, as in pixel microlensing. We find that the relative number of c...

UNLABELLED A chemical burn refers to irritation and destruction of human tissue caused by exposure to a chemical, usually by direct contact with the chemical or its fumes. The study investigated the trend and complications following chemical burns and their management. METHODS The study involved a retrospective review of Burns Registry at the Burns Intensive Care Unit of the Komfo Anokye Teac...

In computer graphics, bright patterns of light focused onto matte surfaces are called “caustics”. We present a method for rendering dynamic scenes with moving caustics at interactive rates. This technique requires some simplifying assumptions about caustic behavior allowing us to consider it a local spatial property which we sample in a pre-processing stage. Storing the caustic locally limits c...
