Developing an intuitionistic fuzzy rough new correlation coefficient approach for enhancing robotic vacuum cleaner.

An intuitionistic fuzzy rough model is a powerful tool for dealing with complex uncertainty and imprecision in graph-based models, combining the strengths of intuitionistic fuzzy sets and rough sets. In this research, a correlation coefficient is an established tool for finding the strength of the relationship between two intuitionistic fuzzy rough graphs since correlation coefficients are very capable of processing and interpreting data. Furthermore, an intuitionistic fuzzy rough environment is integrated with attribute decision-making based on correlation coefficients.

Optimal time management on linear accelerator: A logical model to reduce patient waiting time.

Introdction: Optimal time management is of utmost importance in the radiotherapy department. Inappropriate allocation of time slots leads to prolonged waiting times and decreased patient satisfaction during external beam radiotherapy. The present study tests a logical model to improve the waiting time for the patients.

Immobilization versus no immobilization for pelvic external beam radiotherapy.

Aim: To identify the most reproducible technique of patient positioning and immobilization during pelvic radiotherapy.

Background: Radiotherapy plays an important role in the treatment of pelvic malignancies. Errors in positioning of patient are an integral component of treatment.

Physiologically clotted fibrin-calcined bone composite--a possible bone graft substitute.

Fibrin plays a major role in blood clotting and is important in wound healing. In the present study, physiologically clotted fibrin (PF) and calcined bone (CB) both of bovine origin were used in the preparation of a bone graft material with chitosan (C) as a binder. This bone graft (PF-CB) was characterized by stress-strain analysis, X-ray diffraction (XRD) studies, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and FTIR spectroscopy.

An in vivo study of hydrogels based on physiologically clotted fibrin-gelatin composites as wound-dressing materials.

In this study we have reported the efficacy of three biomaterials: (a) physiologically clotted fibrin-gelatin composite (PFG), (b) PFG graft copolymerized with 2-hydroxyethyl methacrylate (PFG-HEMA), and (c) PFG graft copolymerized with 2-hydroxypropyl methacrylate (PFG-HPMA) as temporary wound-dressing materials using the rat as an animal model. Full-thickness excision wounds were made on the back of female rats weighing about 150 +/- 10 g. The dressings were applied on the wounds and changed periodically at an interval of 4 days with the respective materials.
