To determine cholesterolin biologicalfluids,use of the ferric chloride-sulfuric acid reagent introduced by Zlatkis et al. (1) is relatively simple and reliable (2, 3), and the sensitivityof the reagent for cholesterol is four to five times greater than that of the Liebermann-Burchard reagent (2). However, Parekh and Jung (4) reported that hydrogen chloride is evolved during the ferric chloride-...

A new exhaust aerosol model CFD-TUTEAM (Tampere University of Technology Exhaust Aerosol Model for Computational Fluid Dynamics) was developed. It is based on modal aerosol dynamics modeling with log-normal assumption of particle distributions. The model has an Eulerian sub-model providing detailed spatial information within the computational domain and a computationally less expensive, but spa...

a new model is proposed in this research to calculate the longitudinal strengthof unidirectional e-glass reinforced polymer composites exposed to sulfuricacid environment, using a micromechanics model. in the proposed method,it is assumed that the residual strength of the degraded composites under acidic environment can be calculated by knowing the degraded strength properties of the constituen...

Introduction: Sulfur is a major chemical component of the Martian surface materials and is thought to have a volcanic origin. Pathfinder and Viking chemical analyses revealed SO3 compositions of “soils” and dust from about 4 to over 7 wt. % [1,2]. Although we know that S is chemically important, we do not know its speciation. Small amounts of sulfates (e.g., Ca and Mg sulfates) and sulfides (e....
