Improved Global Region based Chan-Vese Model
Abstract: Chan-Vese model is one of the fundamental active contour models for image segmentation. In this paper, the authors propose an improved global region based Chan-Vese model which provides solution to some limitations of basic Chan-Vese model. The proposed model avoids re-initialization requirement to increase speed of algorithm by reaction-diffusion method. The stopping criterion to stop segmentation process is also added in the model. To make model automatic, initialization free feature …

Concept of Free Radical Theory in Ayurveda
Abstract: A free radical can be defined as any molecular species capable of independent existence that contains an unpaired electron in an atomic orbital. Free radical is produced as an intermediate product during metabolism of fat, carbohydrates and protein in body. Free radicals are known to attack the structure of cell membranes which then create metabolic waste products. Free radicals are capable of damaging biological entities (due to their unstable and …

Polymer Modifications (Grafting): Approach to Enhance Versatility of Natural/Renewable Polymeric Materials
Abstract: Graft copolymers are branched copolymers containing a long chain of one monomer called preformed or backbone polymer and branches/grafts of long sequences of usually another monomer. A number of monomeric units can be grafted on the biopolymeric backbone by free radical graft copolymerization reaction using chemical free radical initiator to produce reactive sites on the backbone of biopolymer. The chemical combination of natural and synthetic polymers yields new materials which …

Dissipative Particle Dynamics Simulation Study on the Evolution of Photoinitiated Free Radical Polymerization Crosslinked Networks
Abstract: Gradient polymer materials overcome the limitations of conventional homogeneous polymers by integrating multiple distinct functionalities within a single continuous structure. Although photoinitiated free-radical polymerization offers excellent spatial and temporal control, the underlying microscopic mechanisms governing network evolution under non-uniform light fields remain poorly understood. In this study, a mesoscale dissipative particle dynamics (DPD) model was successfully developed to couple free-radical polymerization kinetics—including initiation, propagation, crosslinking, and termination—with exponential light attenuation …

Structure–Property Relationships in Poly (N isopropylacrylamide) Hydrogels: Toward Thermoresponsive Polymer Composites
Abstract: Poly(N-isopropylacrylamide) (PNIPAAm) hydrogels can shift from solid to gel and back again at body temperature. Due to their lack structural integrity, thermal stability, and mechanical strength, they are difficult to use. This study mixed PNIPAAm with biocompatible fillers like chitosan and silicon nanoparticles to create hydrogels with superior structure-property correlations. Free radical polymerization with ammonium persulfate/TEMED initiator and N,N′-methylenebisacrylamide crosslinker produced the composites. Scanning electron microscopy showed a denser, interconnected …
