Some Observations on Definitions of Voltage Unbalance

Abstract: In this paper an analysis of five different definitions of voltage unbalance developed by various power communities (CIGRE, NEMA, IEEE, and IEC) is presented, in order to understand their performance and difference among them. The purpose of this work is to analyze and quantify the voltage unbalance, so that these results may become useful to minimize the harmful effects of voltage unbalance. To quantify the voltage unbalance, five existing voltage unbalance definitions are calculated and their numerical values are used in analyzing the behavior of these definitions for the unit change in their magnitude and angle of voltage phasors.

A novel CFD analysis to minimize the spread of COVID-19 virus in hospital isolation room.

Abstract: The COVID-19 is a severe respiratory disease caused by a devastating coronavirus family (2019-nCoV) has become a pandemic across the globe. It is an infectious virus and transmits by inhalation or contact with droplet nuclei produced during sneezing, coughing, and speaking by infected people. Airborne transmission of COVID-19 is also possible in a confined place in the immediate environment of the infected person. Present study investigates the effectiveness of conditioned air released from air-conditioning machines to mix with aerosol sanitizer to reach every point of the space of the isolation room so as to kill the COVID-19 virus which will help to protect the lives of doctors, nurses and health care workers. In order to numerically model the laminar-transitional flows, transition SST k-e model, which involves four transport equations are employed in the current study. It is found from the analysis that high turbulent fields generated inside the isolation room may be an effective way of distributing sanitizer in entire volume of isolation room to kill the COVID-19 virus.

Chitosan Aerogels Exhibiting High Surface Area for Biomedical Application: Preparation, Characterization, and Antibacterial Study

Abstract: The objective of the present work is to improve the surface area of aerogel via supercritical carbon dioxide (sc · CO2) treatment and thus to obtain the chitosan derivative. The resulting mesoporous material exhibits the typical characteristics of aerogels such as high porosity and high surface area. The aerogels were characterized using FTIR, SEM, TEM, and thermal analysis. The specific surface areas and porosities of aerogels were determined using N2 adsorption. The antibacterial assays were done using E. coli. The prepared chitosan aerogels show important properties such as biocompatibility, non-toxicity, and antibacterial activity, making them suitable for biomedical applications.

Opacity and plasmonic properties of Ag embedded glass based metamaterials

Abstract: Plasmon resonance in noble metals at the nanoscale is technologically important for various applications in plasmonic devices The synthesis and optoelectronic properties of silver based plasmonic metamaterials by the ion-exchange (Ag+–Na+) method in a soda-lime glass matrix have been investigated The effects of annealing temperatures on plasmonic resonance of silver nanoclusters are discussed During annealing the Ag+ is reduced to Ag0 and subsequently forms silver nanoparticles in the oxidizing atmosphere The particle sizes calculated from Mie theory are in excellent agreement with the size measured from FEGTEM The prepared materials were characterized by XRD, UV-vis, RBS, XPS and Raman spectra
