Evaluation of Cashew Nut Shell Liquid Derived Isocyanate Blocking Agents
Authors : Pietro Campaner,Yun Mi Kim,Chetan Tambe,Anbu Natesh,


Cardanol(3-pentadecenyl-phenol) is a well-known non-edible natural oil derived from Cashew Nutshell Liquid and represents a valid alternative to petro-based derivatives (e.g. nonylphenol) as a protective group (blocking agent) for isocyanates. In fact, once used in polyurethane prepolymers, this substance demonstrates various benefits including favorable deblocking conditions, lower viscosity,... Read More

On Approach to Increase Integration Rate of Elements of a Digitally Controlled Oscillator
Authors : E.L. Pankratov,


In this article, we consider an approach for increasing the density of field-effect transistors, which comprised of a digitally controlled oscillator. Based on this approach, we describe manufacture of this oscillator in a heterostructure with specialized structure. Doping of some specific regions of the considered heterostructure should be done by using diffusion type of doping or by ion type of... Read More

On Non-Parametric Criteria for Random Communication and Processes Relationship
Authors : Abdulkarim Farah,Amer Dababneh,Amjed Zraiqat,


The properties of partially dependent random variables, representing the extreme (turning) point of time series have been investigated. Asymptotic normality of sums of partly dependent random variables has been proven. Generalization of Kolmogorov inequality has been... Read More

Supply Chain and Value Chain Engineering – Review
Authors : Rajesh Shankar Priya,Vincent Aroulmoji,


Supply chain is a widely discussed topic in the last decades. The Just-in-Time concept in manufacturing was a massive success towards the end of the millennium. The Just-In-Time delivery has become a crucial indicator of a company’s competitive advantage. Whilst Supply Chain is an integral part of logistics, this paper systematically reviews the fundamentals of supply chain including the... Read More

Synthesis and Characterization of Pure and Mg Doped Hydroxyapatite Nanoparticles for Orthopaedic and  Dental Applications
Authors : M. Nandhini,K. Surya,V. Kalaiselvi,N. Vidhya,V. Ramya,


In the present study pure hydroxyapatite (HAp) and Magnesium (Mg) doped hydroxyapatite (HAp) powders were prepared by using chemical precipitation method. The samples were characterized by XRD, FT-IR, SEM, EDAX, UV and PL. The Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed to analyze the morphology and crystal structure of Pure Mg and Mg Doped Hydroxyapatite... Read More

Covid-19 is a coronavirus disease set off from China in 2019 and it has spread as a pandemic throughout the world, causing more than a million deaths and leaving several millions of people to struggle with acute respiratory and throat infections. It has wide-ranging effects on human health and functioning of vital parts in the body. In acute cases it affects the normal functions of the kidneys,... Read More

On Prognosis and Optimization of Downconversion of  Mixer Manufacturing with Increasing of Density of their Elements with account of Miss-Match Induced Stress and Porosity of Materials
Authors : E.L. Pankratov,


In this paper we introduce an approach for prognosis of mass transport in heterostructures during manufacturing of circuits of a downconversion mixer. The approach gives a possibility to take into account spatial and temporal variations of parameters of mass transport at one time. At the same time the approach gives a possibility to take into account nonlinearity of mass transport and analyze... Read More

Electronic Gadget Detection Using Giant Magnetoresistive Sensor
Authors : S. Senthil Murugan,Dasari Aravind Babu,


This work reveals the presence of an Electronic gadget where it is misused/restricted/prohibited in the premises. The objective of this work is to detect the electronic gadget, which is exhibiting magnetic field even when it is in Power off/Airplane mode. This detector concentrates only on some major parts which are used in the mobiles/electronic gadgets for the purpose of detection and then... Read More

Synthesis and Characterization of Pure and Capped Zinc Oxide Nanoparticles Using Nigella Sativa
Authors : P. Nandhini,K. Surya,V. Kalaiselvi,V. Ramya,N. Vidhya,


In this present study ZnO nanoparticles were synthesized with and without Nigella sativa seed extract by using Microwave irradiation method. The synthesized nanoparticles were characterized by XRD, FT-IR, SEM and EDAX techniques. The results of X-Ray Diffraction (XRD) predict crystalline nature and spherical shaped structure of the synthesized nanoparticles. The Functional groups of the... Read More

We compute minimum covering Maximum degree energy of some standard graphs and obtain upper and lower bound for this energy. Also obtain the minimum covering Maximum degree energy of thorn graph of some standard graphs.... Read More

 Performance Analysis of FPGA based Implementation of FFT Architecture with Pruning Algorithm for Industrial Applications
Authors : P. Suresh Kumar,S. Meenakshi,


In the present study the improved architecture of Inverse Fast Fourier Transform (FFT) is developed and presented. The number of arithmetic operation is more in the normal working of conventional Inverse Fast Fourier Transform. An enhanced pruning algorithm is utilized to reduce the number of arithmetic operations in the FFT architecture. The performance of the improved FFT architecture is... Read More

Microwave Assisted Pure and Mg Doped Tungsten Oxide WO3 Nanoparticles for Superconducting Applications
Authors : V. Hariharan,V. Aroulmoji,K. Prabakaran,V. Karthik,


The aim of the present work focuses the role of “Mg” in WO3.H2O nanopowders, doped with Magnesium using a facile microwave irradiation process and the annealing process was carried out at 600°C in air for 6 h in order to remove the impurities and enhance the crystallinity of the end products. The samples were further characterized by powder X-ray diffraction, field emission... Read More
