Item A Bivariate Teissier Distribution: Properties, Bayes Estimation and Application(Springer, 2024) Sharma V.K.; Singh S.V.; Pathak A.K.This article presents a bivariate extension of the Teissier distribution, whose univariate marginal distributions belong to the exponentiated Teissier family. Analytic expressions for the different statistical quantities such as conditional distribution, joint moments, and quantile function are explicitly derived. For the proposed distribution, the concepts of reliability and dependence measures are also explored in details. Both the maximum likelihood technique and the Bayesian approach are utilised in the process of parameter estimation for the proposed distribution with unknown parameters. Several numerical experiments are reported to study the performance of the classical and Bayes estimators for varying sample size. Finally, a bivariate data is fitted using the proposed distribution to show its applicability over the bivariate exponential, Rayleigh, and linear exponential distributions in real-life situations. � Indian Statistical Institute 2023.Item Biochar enhances carbon stability and regulates greenhouse gas flux under crop production systems(Elsevier, 2024) Barman A.; Bera A.; Saha P.; Dey S.; Sen S.; Meena R.S.; Singh S.V.; Singh A.K.Soil carbon is crucial for food security, ecosystem functioning, greenhouse gas (GHG) mitigation, and environmental sustainability in extreme climate vulnerabilities. The GHG emissions usually rise along with agronomic practices, anthropogenic activities, paddy cultivation, fertilizer use, and livestock. In this context, biochar, a rich carbon source, produced by the process of pyrolysis of biomass, is a stable form of carbon that enhances soil organic carbon sequestration. Due to the presence of carbon in an aromatic state, biochar is critical for carbon sequestration and resistant to microbial decomposition. Recently, surplus biomass or crop residues from various production systems have gained a lot of attention due to their serious implications for environmental sustainability. Instead of increasing ecological pollution by burning, surplus crop residues from various agricultural production systems can be converted to biochar by pyrolysis, which offers safe and sustainable disposal of excess crop residues of crop production systems along with GHG mitigation co-benefits. Thus, biochar application may provide a long-term solution to combating climate change with other benefits. However, there is limited knowledge available about the effect of biochar application on carbon stability and GHG emissions fluxes under crop production systems. � 2024 by Elsevier Inc.

Utilizing biochar effectively may make it possible to control soil health and encourage fertility. Millions of tonnes of biomass and crop waste that aren't used as animal feed might be converted into biochar to boost the carbon content of the soil. The high surface area, cation exchnage capacity, high water-holding capacity, pore size; volume, and distribution, as well as molecular structure of biochar, among other chemical, physical, and biological characteristics, can increase nutrient availability and microbial communities for enhancing soil quality. Biochar also reduces the greenhouse gas emission from crop fields and acts as natural filtration media for water and air purification. It can also be effectively used for soil health remediation and reclamation of degraded soils. Biochar has high adsorption properties which help in the removal of heavy metals from wastewater. Thus, biochar has a diverse arena of applications and can be easily derived from any lignocellulosic biomass. � 2024 by Elsevier Inc.

Development of nanocomposites have been attempted to ensure the supply of essential nutrients to the plants by improving the soil fertility. This has been attempted through the deployment of nanoparticle-based smart delivery systems. Among the abiotic stresses, heavy metal stress has been known to significantly effect plant performance, thereby impacting the yield. In this connection, carbon-based nano-adsorbents (carbon nanotubes, carbon nanoparticles and graphene) and metal-based nano-adsorbents (magnetic nanoparticles) are the two primary categories of nano-adsorbents that can be used for nullifying the effect of heavy metals present in soil. Therefore, these nano-adsorbents can be used to treat polluted soils under in-situ or ex-situ conditions, thereby improving soil health and fertility. This chapter presents the application of environment-friendly nanomaterials to reduce heavy metal toxicity in the soil. � 2024 selection and editorial matter, Swarnendu Roy and Akbar Hossain; individual chapters, the contributors.Item Enhancement in photo-response of CuZnS nanocrystals-based photodetector using asymmetric work function electrodes(Elsevier B.V., 2024) Dahiya S.; Hazra S.; Pandey U.; Pramanik S.; Dahiya P.; Singh S.V.; Kumari N.; Pal B.N.In this study, an efficient visible light photodetector has been fabricated by using heavy metal-free CuZnS Nanocrystals with average particle size of 13 � 1 nm and has been synthesized by a microwave (MW) assisted synthesis technique. The optical band gap of this nanocrytstal is ?1.7 eV and has an absorbance spectra ranging from 300 to700 nm.

Various categories of problematic waste exist, including agro-industrial, municipal solid waste, plastic waste, and electronic waste. The exploration of these different waste types and their subsequent treatment is of great interest, as they hold the potential to serve as secondary raw materials or be employed for generating energy in waste management processes. Amidst a range of thermochemical conversion methods, the processes of pyrolysis and gasification applied to problematic wastes blended with different types of biomasses have emerged as promising technologies. These technologies offer the potential to establish an ecologically sound waste management system, leading to substantial reductions in pollution while simultaneously maximizing the recovery of energy and materials. The outputs obtained from the conversion of these waste materials include syngas, biochar, and fuel, which can be effectively utilized for various purposes in an environmentally sustainable manner. Consequently, subjecting problematic wastes to thermal degradation and transforming them into useful resources presents a viable long-term strategy for addressing climate change alongside other advantages.

This cutting-edge technology enables the establishment of multiple connections all at once and maintains network ubiquity even in settings that involve high levels of mobility or densely populated areas. As a result, smart cities and intelligent transport systems may stand to benefit from its use. 5G will make it possible for the actual Internet of Things and the Internet of Vehicles to become a reality if this plan is implemented. The advent of 5G will herald the beginning of a new era of opportunities for networks and services. It will help in maintaining an increased data rate, reduced latency, huge simultaneous connections, and ubiquity of networks around the world. 5G will also be a crucial enabler for a true Internet of Things because of its capacity to connect a vast number of sensors and actuators while following severe energy efficiency and transmission limits. The Internet of Things (IoT), a new digital communication paradigm, has made it possible for things that are often found in daily life to interact with one another as well as with people [6]. As a result, the objective of the Internet of Things is to expand both the breadth and depth of the Internet. This will be accomplished by making it easier for a wide variety of devices, including vehicles, home appliances, security cameras, industrial actuators, and many more, to interact with one another in an unobtrusive manner. When 5G is applied to the Internet of Things in cities, it may be able to keep track of the total amount of energy that is consumed by all of the city's public services (including lighting, traffic lights, security cameras, and the heating and cooling of public buildings, amongst other things). Municipalities will, among other things, be able to manage their energy resources more effectively if they have access to this information. � 2024 Bentham Science Publishers.Item Understanding sustainable tourist behaviour through a critical perspective of motivation, personality, attitude, and environment(IGI Global, 2024) Kumar A.; Singh S.V.; Singh K.This study utilises the findings of prominent researchers to examine a critical viewpoint of tourist behaviour (T.B.) through an analysis of different constructs, theories, and models primarily focused on four socio-psychological constructs: motivation, personality, attitude, and environment. The results demonstrate the significance of socio-psychological frameworks in the management of travel itineraries. The comprehension of visitors' conduct is a complex undertaking due to its dynamic characteristics and its continual susceptibility to several social and psychological dimensions, such as perception, motivation, personality, and environment. The practical implications of this study center around need for destination managers, businesses, and policymakers to re-evaluate their strategies and prioritise responsible, inclusive, and sustainable tourism practices that are consistent with the key perspectives on motivation, personality, attitude, and environment. � 2024, IGI Global.
