The corrosion definition is not constrained to alloy and metals, but rather the term, corrosion, can likewise be stretched out to earthenware production and other nonmetallic materials. Corrosion can prompt to problems significant in furthest fields for man-factory [1]. Corrosion gets to be distinctly a standout amongst the most difficult points for researchers and the society for building. Fro...

The aim of this study is to investigate and demonstrate the mechanical and corrosive characteristics of the neodymium-containing magnesium alloy MgNd2 (Nd2), which can be used as a resorbable implant material, especially in the field of stenting applications. To determine the mechanical characteristics of Nd2, tensile and compression tests were initially carried out in the hot extruded state. H...

Disaster researchers have debated the utility of distinguishing “natural” from “technological” catastrophes. We suggest that litigation serves as a source of chronic stress for victims of human-caused disasters involved in court deliberations for damages. Data from the Exxon Valdez oil spill are used to evaluate a social structural model of disaster impacts three and one-half years after the ev...

Here, we report a case of corrosive injury-induced pharyngeal stricture in a 69-year-old female, which was successfully treated with endoscopic adhesiolysis using an electrosurgical knife. The patient had ingested sodium hydroxide in an attempted suicide, and immediate endoscopy revealed corrosive injuries of the pharynx, esophagus, and stomach. When a liquid diet was permitted, she complained ...

Introduction: Corrosive ingestion is the major cause of esophageal stricture in our country. Mitomycin–C, an anthracycline derived from Streptomyces caespitosus, has both antineoplastic and antiproliferative properties. Use of mitomycin–C have been well documented in various ophthalmologic procedures and laryngo-tracheal conditions where it has been shown that mitomycin–C inhibited fibroblast p...

Potassium diformate (Formi) is odorless, low-corrosive and easy to handle. The European Union (EU) has approved it as non-antibiotic growth promoter, for use in non ruminant feeds. Maximum inclusion level of potassium diformate is 1.8% as registered by the European authorities which can improve weight gain up to 14%. Potassium diformate contains the active ingredients free formic acid as well a...

Chromate conversion coatings have been in service for decades providing robust corrosion protection to a wide variety of aluminum alloys. However, it is also known that anti-corrosive containing Cr 6+ contributes DNA damage, cause cancer and are not environmentally friendly. Consequently, regulatory restrictions over the use were established mitigate environmental damage health problems. To ans...
