Papillomatosis is a condition in farm animals and is treated by surgical excision or application of certain caustic agents. Contrary to it, two cattle with teat warts were treated by an alternative method by using the thuja occidentalis (thuja-30, a homeopathic medicine) @ 10 drops Per os twice a day for a span of 3 weeks and lead to complete recovery.

Four of nine exoplanets found by microlensing were detected by the resonant caustic, which represents the merging of the planetary and central caustics at the position when the projected separation of a host star and a bounded planet is s ∼ 1. One of the resonant caustic lensing events, OGLE-2005-BLG-169, was a caustic-crossing highmagnification event with Amax ∼ 800 and the source star was muc...

This paper proposes a robust algorithm to compute caustics caused by multiple reflections and refractions on the GPU. The proposed algorithm solves two problems of previous methods, caustic light leaks and caustic undersampling. In order to eliminate caustic light leaks, terminal photon hits are stored and caustic patterns are reconstructed on the faces of a layered distance map attached to the...

A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion....

Caustic injury to the aerodigestive tract remains a significant medical and social concern despite various efforts to minimize hazards of caustic household products. Agents with a pH less than two or greater than 12 are extremely corrosive, causing damage that can range from mild to extensive, including esophageal perforation leading to mediastinitis and death at the extreme scale. Methods incl...

Background. Inspite of the fact that accidental caustic ingestion is an entirely easily preventable problem, it has however persisted in rural Nigerian communities because the commonly implicated agent which is caustic soda (sodium hydroxide, NaOH) is sold in open markets without restrictive legislations. This study aims to identify the perpetuating factors of paediatric caustic ingestion and r...

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

background: sulfur compounds must be removed from petroleum because they contribute to environmental pollution. a strong alkaline solution such as caustic soda is used to remove these compounds. this spent caustic has high values for chemical oxygen demand (cod) concentration, ph and total sulfur. in this study, the regeneration and treatment methodology of sulfidic spent caustic was investigat...

Irregularities in the perimeter of a water droplet adhering to a vertical pane of glass cause perturbations in the curvature of the droplet surface. When laser light passes through such a droplet, the perturbations produce a far field refraction caustic, which is a section of the caustic known as the parabolic umbilic in the catastrophe theory classification. As the water evaporates and the dro...
