The evaluation of reactive chemical hazards at the pilot and manufacturing scale, using laboratory testing, is increasingly used and has been well documented. However, reactive chemical hazard evaluation at the R&D scale presents special challenges. The typical hazard testing program requires a significant amount of sample, often takes time (>3 days) to complete, and is can be quite costly. On ...

the purpose of this study was proposing a suitable pattern for evaluating and assessing companies. to reach this important goal, the fuzzy delphi method (fdm was employed. after the evaluation pattern was created, the fuzzy analytic hierarchy process (fahp) was used in order to find the weight of all selected factors, and the significance of each of evaluation factor was determined. next, compa...

This paper presents the development of a model based decision support system with a case study on solving the supplier selection problem in a chemical processing industry. For the evaluation and selection of supplier, the analytical hierarchy process (AHP) and grey relational analysis (GRA) were used. The intention of the study is to propose an appropriate platform for process industries in ...

sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. they are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. in this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwa...

The active parts of 11 medicinal plants were analyzed for physico-chemical evaluation, phytochemical determination and antioxidant activity. The physico-chemical evaluation revealed that highest water soluble extractive was from Origanum vulgare (38%), highest chloroform extractive was from Psoralea corylifolia (21%); highest ethanolic extractive was that of Acorus calamus (11%) and the highest...

The importance of reliable methods for representative sub-sampling in terms of experimental design and risk assessment within the European Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) system is crucial. We developed experimental design approaches, by utilising predicted properties and the 'distance to model' parameter, to estimate the benefits of certain compound...

In this paper, proposing visualized and quantitative evaluation methods for validation dimensionality reduction techniques performance. Four well known techniques for dimensionality reduction evaluated, verify the capacity of generating a lower dimensional chemical space with minimum information error. Real chemical database used to generate a sample with specific structure as an input to evolu...

The previously published structure of the fungal metabolite acremine P is revised by re-evaluation of chemical shift values and NOESY data, and by DFT calculations.
