Dysphagia is a common yet alarming symptom reported by patients during routine visits to outpatient clinics of gastroenterology. Most them have chronic history gastroesophageal reflux disease and use proton pump inhibitors or anti medications for years. The agonising part that they are not referred the physicians in general practice. One major reasons behind this persistent reluctance go invasi...

Corrosive Sulfur in transformer oil has been the cause of high profile transformer failures in recent years. Oil treatments consisting of copper passivators have been only partially effective. DSI has discovered a multi-step method that has been proven to change oils with corrosive sulfur into non-corrosive status, as well as significantly slowing oxidation and ageing of insulating oil and pape...

Simulation results from using the cellular automata as an example of defects on the surface of austenitic stainless steel 08Cr18Ni10Ti are presented in this paper. Practical confirm the feasibility of the proposed method for simulation modeling of corrosive process of steel in neutral environments.

An 18 year old man developed recurrent haematemesis 12 years after colonic interposition for corrosive injury to the oesophagus. A colonic ulcer close to the cologastric anastomosis appeared to have fistulated into the cavity of the left ventricle. This so far unreported complication needs to be considered when patients who have had coloesophageal substitution present with gastrointestinal blee...

A highly efficient and industrially viable catalyst design for the direct synthesis of H(2)O(2) from H(2) and O(2) was realized by the encapsulation of Pd nanoparticles in polyelectrolyte multi-layers on a sulfonated resin. The continuous production of 9.9 wt% H(2)O(2) was achieved under intrinsically safe and non-corrosive conditions without any loss of activity.

We reviewed 64 patients with perforation or full-thickness injury of the alimentary tract after acid ingestion. Based on our classification of laparotomy findings, there were class I (n = 15); class II (n = 13); class III (n = 16); and class IV (n = 20). Study parameters were preoperative laboratory data, gastric perforation, associated visceral injury, and extension of the injury. End points o...
