Engineering product quality control at all stages of product life

Formulation and quality control of a topical gel product for treatment of melasmaFormulation and quality control of a topical gel product for treatment of melasma

Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as ...

Issues in Product Life Cycle Engineering Analysis

Traditional engineering analysis of product designs has focused primarily on a product's operational performance without considering costs of manufacturing and other stages downstream from design. In contrast, life cycle analysis of a product during its initial development can play a crucial role in determining the product's overall life cycle cost and useful life span. This paper examines prod...

Re-use of Product Model through Life-cycle Stages

This paper discusses the requirements on product model presentations that are suitable for reuse. The aim is to define promising directions for future research by recognizing how the characteristics of reuse entities vary at the different stages of the product life-cycle. Reuse entities are roughly categorized into three types of presentation entities: macroscopic principles for the early stage...

Effectiveness of sulfuryl fluoride for control of different life stages of stored-product psocids (Psocoptera).

With the phase-out and impending ban of methyl bromide, sulfuryl fluoride is among the most promising alternative fumigant insecticides for control of stored-product insect pests. It has been evaluated for control of several stored-product insect pests, but there are few data available on its efficacy for control of stored-product psocids (Psocoptera). We evaluated sulfuryl fluoride for control...
