This is part of a series of review articles on formaldehyde-releasers and their relationship to formaldehyde contact allergy. Formaldehyde-releasers used in metalworking fluids (MWF) and a group of releasers not presented in previous articles are discussed. Here, in Part 1 of the article, there is a short overview of the composition and functions of MWF, the function of biocides in them, and ad...

Preservatives are chemicals that are added to products that contain an aqueous phase. These include cosmetics, topical medications, household products, foods, and industrial products such as glues, paints, dyes, metalworking fluids, and spin finishes. They are biocidal or biostatic, inhibiting the overgrowth of micro-organisms and protecting and retarding the chemical degradation of the product...

This article examines the experience in 5S methodology implementation in order to optimize the work and safety of the university engineering laboratories, in such a way that the results obtained can be extended to other, similar centers. The research project developed has created an organization culture of all resources in the practice laboratories. A working model was defined to create a 5S st...

Recently, bio-based oil was used as industrial lubricant due to the increasing consideration on environment effect and health issues and in order to replace the usage of petroleum-based oil. The modified vegetable oil exhibit excellent lubrication and tribological performances when compared to the petroleum-based oil. In this study, the crude jatropha oil was modified via chemical modification ...

Little is known about the etiology of pancreatic cancer, which is an important cause of cancer mortality in developed countries. We hypothesize that exposure to cadmium is a cause of pancreatic cancer. Cadmium is a nonessential metal that is known to accumulate in the human pancreas. The major risk factors for pancreatic cancer (increasing age, cigarette smoking, residence in Louisiana, and occ...

Metalworking fluids (MWFs) are widely used in machining process to improve its performance and product quality. It acts as a coolant and lubricant to reduce heat between the contact of two surfaces. However, commercial MWFs used in the industry were usually from petroleum-based oil which is toxic to the environment, difficult to dispose and caused significant health. Therefore, it is essential ...
