Characterizing Preferential Flow Using Iodine-Starch Staining Method and Active Region Model

Modification of flow and compressibility of corn starch using quasi-emulsion solvent diffusion method

Objective(s):The aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. Quasi-emulsion solvent diffusion was used as a crystal modification method. Materials and Methods: Corn starch was dissolved in hydrochloric acid at 80˚C and then ethanol as a non-solvent was added with lowering temperature ...

Dye staining and excavation of a lateral preferential flow network

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Preferential flow features have been found to be important for runoff generation, solute transport, and slope stability in many areas around the world. Although many studies have identified the particular characteristics of individual feat...

Characterizing Physicochemical Properties of Enset Starch

Novel method for quantitative starch penetration analysis through iodine staining and image analysis of cross - sections of uncoated fine paper

This paper presents a novel method for determining starch penetration through iodine staining and microscopic imaging of surface-sized fine paper cross-sections and image analysis of the resulting grayscale images. The more specific aim was to obtain quantitative starch penetration information in the z-direction of the sheet. The penetration information was determined through an image analysis ...

Image Segmentation Method Using Hybrid Region Flow

This paper suggests an efficient image segmentation algorithm in 3 steps for grayscale images. First step is the segmentation as homogenous region on image. And, second step is merging of region without meaningful boundary between segmented regions. At the final step, region, which is considered as meaningless due to composition with minute region, is merged by consideration of similarity with ...
