Novel Cycloaliphatic Cashew Nut Shell Liquid Derivatives and their use as Isocyanate Protective Groups
Authors : Pietro Campaner,Francesca Dinon,Fernanda Tavares,Yun Mi Kim,Anbu Natesh,


Cardanol (3-pentadecenyl-phenol), a well-known non-edible natural oil obtained as a by-product of the Cashew Industry, represents a valid alternative to petro-based derivatives, thanks to its peculiar chemical structure. When selected as polymer building block in the synthesis of epoxy curing agents or polyols and diols for polyurethane applications, cardanol can impart unique benefits, like... Read More

On Optimization of Manufacturing of Instrumentation Amplifier Input Bias Circuitry to Increase Density of Elements
Authors : E.L. Pankratov,


In this paper, we introduce an approach to increase density of field-effect transistors framework instrumentation amplifier input bias circuitry. Framework the approach, we consider the manufacturing of inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. Moreover, do pant and radiation defects... Read More

Rigid and Non-Rigid Rotor Models for Microwave Rotational Spectroscopy of Diatomic Molecules
Authors : Rohit Singh,


In microwave rotational spectroscopy, absorption spectra arise from molecular rotation and correspond to transitions between the rotational energy levels associated with a given vibrational state of a particular electronic state. The rotational transitions, which fall in the microwave region, are induced through the interaction of the molecular electric dipole with the electric vector of the... Read More

Solving a Demand-Supply Mismatch by Enabling a Value Chain Orientation
Authors : Rajesh Shankar Priya,


Supply-Demand mismatch is a continuous challenge among suppliers creating poor customer service levels and often leading to higher costs to the entire supply chain, to meet the demands of the customer. This paper will highlight demand-supply mismatch issues between a steel supplier having supply issues with one of its premier automobile customers due to difficulties in forecasting the appropriate...

How to improve the Quality of Indian Engineering Education using TQM Principles and ICT Tools
Authors : R.V. Mahendra Gowda,


Education in India, especially the Engineering Education is facing a lot of disinterest and disruptions. Further, the onset of Covid-19 pandemic has greatly affected the quality of education and revolutionized the entire method of teaching, learning, assessment and examination system in our nation. For the last one year, there is an almost absence of face-to-face teaching, there are no proper... Read More

Hydrogels for Textile Applications - Review
Authors : Usha Sayed,Ishika Deshmukh,


Hydrogels are widely used in biomedical area of research. Hydrogels are usually used in fabrication of contact lenses, hygiene products, biosensors, wound dressings, and tissue engineering applications. The polymer 2-hydroxyethyl methacrylate (HEMA) based hydrogel synthesis and their use in textiles industry was also reviewed. Poly-Hema is a soft, flexible, water absorbing plastic used in making...

Ammonium Persulphate Initiated Graft Copolymerization of Aniline onto Chitosan-A Comparative Kinetic Study
Authors : Seyed Hossein Hosseini,


Ammonium persulphate (APS) has been used as efficient initiator for graft copolymerization of the aniline (ANI) onto chitosan at 25±0.1°C. Graft copolymerization of ANI onto chitosan has taken place through the cation radical initiation process. The grafting parameters have been evaluated by varying concentration of ANI, APS and chitosan. The effects of concentration of APS, ANI, chitosan... Read More

Hyaluronic Acid - 2-Deoxy-D-Glucose Conjugate Act as a Promising Targeted Drug Delivery Option for the  Treatment of COVID-19
Authors : R. Thirumalaisamy,V. Aroulmoji,Riaz Khan,C. Sivasankar,M. Deepa,


In the present study, we propose Hyaluronic acid - 2-Deoxy-D-Glucose (HA-2DG) conjugate as a novel drug for the treatment of COVID-19. In silico molecular docking studies HA-2DG and 2-Deoxy-D-Glucose (2DG) against four different SARS-CoV-2 viral protein (Mpro, RdRp, PLpro and S protein) revealed that HA-2DG conjugate showed better binding affinity (-6.2, -7.2, -7.0 and 6.4 Kcal/mol) with all four...

Mechanisms of Earthquake-Induced Ionosphere Perturbations -An Overview
Authors : Jyoti Singh,Geeta Lather,Ajoy Gosh,S. Choudhary,


The study of atmospheric–ionospheric connections is one of the most exciting and potentially important disciplines in geophysics. Changes in the ionospheric environment might be a method for earthquake prediction. The phenomenon of lithosphere-atmosphere-ionosphere (LAI) coupling is a promising method for earthquake prediction. Various experiments can be used to determine the variability... Read More
