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,

https://doi.org/10.29294/IJASE.7.4.2021.1936-1942

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,

https://doi.org/10.29294/IJASE.7.4.2021.1943-1949

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...

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

https://doi.org/10.29294/IJASE.7.4.2021.1975-1982

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
