Overview of Green Nanofabrication Technologies for Food Quality and Safety Applications
(Taylor and Francis Ltd., 2023) Pandhi, Shikha; Mahato, Dipendra Kumar; Kumar, Arvind
Green nanotechnology has emerged as a sustainable fabrication technology that has offered tremendous frontiers in the field of food science. This review intends to provide a succinct overview of various green nanofabrication technologies including green creation of nanoparticles using biological sources explicitly from plants as natural reducing agents. In addition, the review explores various biocompatible nano delivery systems for nanoencapsulation of food ingredients for enhancing the sensorial and functional properties food products. Promising applications based on these approaches employing active and smart packaging systems, nanosensors along with functional foods for ensuring food quality and safety have been briefly outlined.

An insight into SARS-CoV-2 membrane protein interaction with spike, envelope, and nucleocapsid proteins
(Taylor and Francis Ltd., 2023) Kumar, Prateek; Kumar, Amit; Garg, Neha; Giri, Rajanish
Intraviral protein�protein interactions are crucial for replication, pathogenicity, and viral assembly. Among these, virus assembly is a critical step as it regulates the arrangements of viral structural proteins and helps in the encapsulation of genomic material. SARS-CoV-2 structural proteins play an essential role in the self-rearrangement, RNA encapsulation, and mature virus particle formation. In SARS-CoV, the membrane protein interacts with the envelope and spike protein in Endoplasmic Reticulum Golgi Intermediate Complex (ERGIC) to form an assembly in the lipid bilayer, followed by membrane-ribonucleoprotein (nucleocapsid) interaction. In this study, we tried to understand the interaction of membrane protein�s interaction with envelope, spike, and nucleocapsid proteins using protein�protein docking. Further, simulation studies were performed up to 100 ns to examine the stability of protein�protein complexes of Membrane-Envelope, Membrane-Spike, and Membrane-Nucleocapsid proteins. Prime MM-GBSA showed high binding energy calculations for the simulated structures than the docked complex. The interactions identified in our study will be of great importance, as it provides valuable insight into the protein�protein complex, which could be the potential drug targets for future studies.

Evaluating combined effect of different coated urea with PGPR on yield and nitrogen use efficiency in lowland rice by regression model and principal component analysis approach
(Taylor and Francis Ltd., 2023) Sharma, Sachin; Bahuguna, Ayush; Parihar, Manoj; Yadav, Janardan; Singh, Surendra
Nitrogen (N) loss is a key problem in rice fields, which results in low nitrogen use efficiency (NUE) of applied N and could be a major limitation from economic and environmental perspectives. In order to improve the NUE, use of slow or controlled released N fertilizers could be a potential alternative to the conventional N inputs. With this objective to evaluate the effect of different slow-release fertilizers on NUE and grain yield of rice, a pot experiment was conducted during kharif 2017 at Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University Varanasi. The experiment comprised thirteen treatments including control, Polymer (PCU) and Neem coated urea (NCU) and their combination with Farm yard manure (FYM) and Plant growth promoting rhizobacteria (PGPR). The combined application of PCU, NCU, FYM and PGPR in treatment T12 provided highest grain yield 47.98 gpot?1and followed by T8 46.60 gpot?1. The result showed that, compared with the PCU treatment T2 (PCU100 Split), the Agronomic efficiency (AE) and Apparent nitrogen recovery efficiency (ANR%) of the mixed doses of coated urea treatment T12 (PCU50 NCU50 FYM10 PGPR Basal) increased by 20.38% and 28.48% respectively. Therefore, application of FYM and PGPR with coated urea improved rice yield, nutrient uptake and their use efficiency and potentially recommended in eastern plain of the Indo-Gangetic Plain for the sustainable production of rice crop. � 2022 Taylor & Francis Group, LLC.
Memory type ratio and product estimators under ranked-based sampling schemes
(Taylor and Francis Ltd., 2023) Aslam, Irfan; Noor-ul-Amin, Muhammad; Hanif, Muhammad; Sharma, Prayas
The exponential weighted moving average (EWMA) statistic is utilized the past information along with the present to enhance the efficiency of the estimators used for estimating the population parameters. In this study, the EWMA statistic is used for the estimation of population mean with suitable auxiliary information. The memory type ratio and product estimators are proposed under ranked-based sampling (RBS) schemes including extreme ranked set sampling, median ranked set sampling, and quartile ranked set sampling. The expressions of mean square errors (MSE) of the proposed estimators are derived. An extensive simulation study is conducted to evaluate the performance of the proposed estimators. An empirical study is presented based on real-life data that supports the findings of the simulation study. � 2021 Taylor & Francis Group, LLC.
Variability of air quality and aerosol over Indian region during 2003�2012
(Springer, 2023) Kumar, Sanjay; Singh, Narendra; Singh, R.P.; Siingh, Devendraa
The Indo-Gangetic basin is one of the biggest, most populated and polluted regions in the world. Satellite- and ground-based data show strong seasonal variability of aerosol loading with a maximum during pre-monsoon (summer) season. In this study, decadal (2003�2012) variability of aerosol optical depth (AOD) derived from AERONET measurements over Kanpur is presented which indicates maximum AOD during 2003 and minimum during 2012. The aerosol size distribution (ASD) exhibits an increase in the radius and a decrease in the width of distribution. It shows an enhancement during 2003 and 2010 and diminished values during 2004, 2007, 2009 and 2011. The ASD is found to show a peak during summer season (pre-monsoon) throughout 2003�2012 only except the years 2008 and 2011. Moreover, for years 2008 and 2011 ASD showed a peak value during a monsoon month (July). Changes in the spectrum of ASD are explained in terms of surface temperature and precipitation. Seasonal variation of aerosol radiative forcing and its climatic impacts have also been discussed. � 2022, Indian Association for the Cultivation of Science.
