An investigation has been made to predict the effects of fore body and after body chitin and chitosan are natural polymers that have many advantages, such as biocompatibility, biodegradability, healing acceleration, non-toxicity, and anti-infection properties. However, the use of pure chitosan films in many applications is limited due to their poor tensile strength and elasticity. Nevertheless, creating biocompatible and biodegradable high-strength composites is of interest to researchers. In this study, chitosan films were reinforced by the addition of chitin fibres and chitin whiskers with

The potential use of chitosan films as a replacement to synthetic polymers in food packaging applications is receiving remarkable attention due to their biodegradability and antimicrobial properties. This study presents the preparation of composite films from chitosan as polymeric matrices, and rice straw and nano rice straw fibres as reinforcements. The films were produced via wet mixing and casting techniques with various reinforcement contents (25–35 wt%). The aim of this research is to investigate the physical, mechanical, chemical, and thermal properties of the synthesized composite films

Multi-slice short-axis acquisitions of the left ventricle are fundamental for estimating the volume and mass of the left ventricle in cardiac MRI scans. Manual segmentation of the myocardium in all time frames per each cross-section is a cumbersome task. Therefore, automatic myocardium segmentation methods are essential for cardiac functional analysis. Region growing has been proposed to segment the myocardium. Although the technique is simple and fast, non uniform intensity and low-contrast interfaces of the myocardium are major challenges of the technique that limit its use in myocardial
