Caustic Ingestions
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...
متن کاملCaustic Object Construction Based on Multiple Caustic Patterns
Inverse caustic problem, that is computing the geometry of a reflector and/or refractor based on a given caustic pattern, is currently not widely studied. In this paper, we propose a technique to solve the inverse caustic problem in which we compute the geometry of a semi-transparent homogeneous refractive object (caustic object) given a directional light source and a set of caustic patterns (e...
متن کاملCaustic ingestion.
Corrosive ingestion is a rare but potentially devastating event and, despite the availability of effective preventive public health strategies, injuries continue to occur. Most clinicians have limited personal experience and rely on guidelines; however, uncertainty persists about best clinical practice. Ingestions range from mild cases with no injury to severe cases with full thickness necrosis...
متن کاملCaustic Forecasting: Unbiased Estimation of Caustic Lighting for Global Illumination
We present an unbiased method for generating caustic lighting using importance sampled Path Tracing with Caustic Forecasting. Our technique is part of a straightforward rendering scheme which extends the Illumination by Weak Singularitiesmethod to allow for fully unbiased global illumination with rapid convergence. A photon shooting preprocess, similar to that used in Photon Mapping, generates ...
متن کاملPoisoning by Lunar Caustic
As poisoning by lunar caustic is very rare, and as the following case made a wonderful recovery, I think it is worth publishing in detail. One day in September last, I prescribed for one of my patients (an old man who had been suffering for a long time from extensive sloughing of the scrotum, which was considerably hyperti'ophiod) a nitrate of silver lotion for external use only. After writing ...
