This article aims to study the effect of concentration with additives on kinematic viscosity crude oils. Additionally, influence solvents that reduces heavy oil significance their functions in flow rate oil, which is transported by conveyor pipes long distances. Different concentrations polymers different types named as Polyvinyl chloride (PVC), Sodium dodecyl sulfate (SDS) and Carboxymethyl ce...
We observed characteristic temperatures connected with different phase transformations in the polycristalline, ferromagnetic GdCo2 sample possible to appear in the temperature range from 300 K to 440 K. We used here three independent methods applied to still the same GdCo2 sample testing in this way the sensivity of each particular method. One of them was the nonconventional, indirect measureme...
Dried ginseng (DG) is in fact the representing ginseng product in the worldwide market. Although it is made in various packages depending on the processing method, size and age of DG, basic scientific data reporting the chemical components are limited. In this study, 4-year-old curved ginseng (CG), one of the domestic DG products, was selected for further investigation. Eighty-six samples of 30...
MOTIVATION Chemical carcinogenicity is an important subject in health and environmental sciences, and a reliable method is expected to identify characteristic factors for carcinogenicity. The predictive toxicology challenge (PTC) 2000-2001 has provided the opportunity for various data mining methods to evaluate their performance. The cascade model, a data mining method developed by the author, ...
