- Abstract:
- ... Protein-protein and protein-starch interactions in the wheat flour decide its suitability for the baking process and can be modified by several physicochemical methods. The present study was undertaken to confirm the protein modification in wheat flour irradiated with ultraviolet (UV) radiation up to the maximum dose of 35 J/cm²/g of flour. Whole wheat (Triticum aestivum) flour samples of two vari ...

- Abstract:
- ... Printed circuit boards (PCB) are the most important and valuable building block of electronic equipment. This metallic fraction present in the PCB is one of the major economic drivers for its recycling. However, the separated nonmetal fraction (NMF) that accounts for approximately 70% of the total weight is usually sent to the landfills.Recently, physical NMF recycling has gained much attention, a ...

BACKGROUND: Tropical forests have been experiencing remarkable rates of transformation over the past century as they are getting degraded or decimated to a great extent by anthropogenic activities. This study aims at investigating the long-term forest cover transformation in Palamau Tiger Reserve (PTR), Jharkhand, India, using Landsat TM, ETM⁺, and OLI satellite images during 1975–2015. The forest ...
