Assessment of Organ-at-risk Sparing in Esophageal Cancer: A Comparative Dosimetric Evaluation of Hybrid, Noncoplanar, and Coplanar RapidArc Plans.

Aim: The purpose of this study is to improve the precision of radiation treatment and sparing of organ-at-risk (OAR) in patients with thoracic esophageal cancer (EC) affecting the heart, lung, and spinal cord. To improve and personalize cancer treatment plans, it assesses the dosimetric benefits of coplanar RapidArc (RA), hybrid arc (RA), and noncoplanar RapidArc (RA).

Materials And Methods: Fourteen patients with EC were chosen for our investigation from our hospital's database.

Dosimetric evaluation and gradient analysis of various MLC leaf-width effects in external beam radiation therapy: TrueBeam Vs Halcyon.

Introduction: This study investigates dosimetric influence and gradient-analysis of leaf-width of various Multi-leaf-collimators (MLC) from Truebeam and Halcyon linear accelerators.

Methods: The leaf-width effects of Millennium120 and HD120MLC from Truebeam and SX1 and SX2 from Halcyon were studied using virtual phantom in Eclipse16.1.

Radiobiological analysis of VMAT treatment plan with flattened and flattening filter free photon beam: an EUD and TCP based comparative study.

Background: This study aimed to evaluate the dosimetric and radiobiological differences between 6MV flattened filter (FF) and flattening filter free (FFF) using volumetric modulated arc (VMAT) technique for head and neck (H&N) cancer patients.

Materials And Methods: Fifteen patients with H&N carcinoma were selected and treated with VMAT with FF (VMAT) treatment plan. Retrospectively, additional VMAT treatment plans were developed using FFF beams (VMAT).

Life cycle assessment of nutrient recovery strategies from domestic wastewaters to quantify environmental performance and identification of trade-offs.

Increase in anthropogenic activities proliferated the consumption of resources such as phosphorus; and increase the adverse environmental impacts especially eutrophication on water resources such as lakes. Nutrient recovery from domestic wastewaters to produce a fertiliser has been explored to address these challenges in the context of a sustainable circular nutrient economy. Life cycle assessment (LCA) was performed to holistically assess the impacts of integrating a nutrient recovery system on wastewater and water resource management using Laguna de Bay, Philippines as the geographical boundary.

Identification and characterisation of antimicrobial compound produced by probiotic Alkalihalobacillus clausii 088AE.

In the present study, Alkalihalobacillus clausii 088AE was evaluated for the production of antimicrobial compounds, their characterisation, and identification. The results showed that, 48-h-old A. clausii supernatant is able to inhibit the growth of indicator bacteria Micrococcus luteus MTCC 106 (7.
