Slaughterhouse Waste water (SWW) features a high degree of organic matter which makes it a significant source of environmental pollution. It has high pathogen content and heavy weight metal speciation pollution potential. Our goal is to determine the water quality in Slaughterhouse Waste water (SWW), then assess the amount of pollutants removed using pure natural biochar adsorbent. Biochar was made from four different natural materials including cow dung, cauliflower and pumpkin pulp and seed...
Air pollution refers to the presence of harmful substances in the air we breathe, and it has become one of the leading global environmental threats to human health, causing serious damage to the environment. Conventional adsorbents are limited by low adsorption capacity, high cost, and non-renewability. The objective of this research is to a new type of hybrid adsorbent consisting of advanced materials like GO and FeBTC functionalized with lower commoditized agro-industrial waste materials in...
This paper proposes a low-cost ultrasound (US) based wireless power transfer (WPT) link for powering lowpower electronics devices used in underwater conditions. The proposed US-WPT link comprises a pair of low-cost ultrasonic transducers, one as a transmitter (Tx) and the other one as a receiver (Rx), and a low-cost full bridge rectifier circuit using Schottky diodes. The paper extensively discussed the modeling of the ultrasound devices, focusing on the energy harvesting perspective and also...
This paper presents a new approach to channel estimation in millimeter-wave beamspace massive MIMO systems. The proposed method is an approximate message passing algorithm that utilizes a flexible discriminative denoiser. The denoiser consists of two parts: a noise level map identifier and a convolutional neural network. By learning the channel structure and estimating the noise characteristics, the denoiser enhances the performance of the message passing algorithm. Simulation results demonst...
This work reports a new technique to include the impact of electromagnetic coupling in computation of the direction of arrival by the linear or rectangular array. Realistic modeling of the transmitter and receiving array have been considered to compute the angles of arrival of a far-field signal. The proposed approach is based on Maxwell’s equations with numerical implementation using the Method of Moment (MoM) technique. Unlike the steering vector based alternate signal estimation algorithms...
In this paper, a prototype is developed for securing healthcare gadgets involved in handling sensitive medical data. The plain vanilla Fitbit architecture is chosen as a use case, and hardware security modules are developed for it with the motivation of securing the Fitbit architecture. The purpose of securing a Fitbit architecture is to address the rising concern about its vulnerabilities to side-channel attacks. The hardware security modules developed for the plain vanilla Fitbit architectu...
The power conversion efficiency of the single junction solar cell is approaching the theoretical limits, which leads to the development of tandem cells. Among various solar cell materials, compound semiconductors such as GaAs and InGaP are the large band gap materials preferred for multijunction solar cells. Besides the broad-spectrum absorption, GaAs and InGaP possess hightemperature stability, radiation resistance, longer minority carrier lifetime, and higher electron mobilities compared to...
The present paper addresses the problem of interval estimation of common scale parameter for two Weibull populations when shape parameters are unknown. The asymptotic confidence intervals, the parametric bootstrap intervals, namely, the bootstrap-p and bootstrap-t are derived. The highest posterior density intervals using the Markov chain Monte Carlo procedure have been derived. Numerical simulation is performed to see the performance of these proposed methods. A real-life example is consider...
Smoke that includes Particulate matter (PM), Carbon monoxide (CO), Sulfur dioxide (SO2), and nitrogen dioxide (NO2), have a substantial negative impact on human health. PM, which can vary from tiny dust to coarse particles, enters the respiratory system and reduces the amount of oxygen taken in by the lungs, leading to hypoxia. Transcription factors called HIFs stimulate genes that help the cells to adjust to hypoxia. Despite its evolutionary separation from mammals, Drosophila melanogaster r...
The discharge of heavy metals such as cadmium (Cd), copper (Cu), nickel (Ni), zinc (Zn), and chromium (Cr) into water bodies poses significant environmental and health challenges. This study explores the sustainable treatment of synthetic wastewater with a metal concentration of 10 mg/L using natural adsorbents and hydroponic phytoremediation techniques. The adsorbents include cotton, gravel, coarse sand, fine sand, and red mud, chosen for their natural abundance and adsorption capabilities. ...
The emergence of industrial activities in various fields such as textiles, cosmetics, and paper has resulted in the widespread discharge of synthetic dyes into waterbodies, which pose ecological and human health risks. Conventional wastewater treatment methods do not always work well to degrade these pollutants. In this respect, Advanced Oxidation Processes (AOPs), including photocatalysis, can be proposed as environmentally friendly and effective solutions for the treatment of wastewater usi...
Insects that thrive in decaying organic matter often act as hidden reservoirs of Clostridium perfringens, carrying the bacterium within their gut microbiota and amplifying its presence in the environment. This ecological relationship enables the dissemination of C. perfringens, particularly its biotype A strains, which produce phospholipase C (Cp-PLC), also known as alpha-toxin. Alpha-toxin is a key virulence factor, disrupting critical signaling pathways in endothelial cells, platelets, and ...
Plant α-amylase inhibitors are proteins naturally produced by plants as part of their defense mechanisms against herbivorous insects. These inhibitors target α-amylase enzymes, which are critical for starch digestion in the insect gut, disrupting their ability to utilize starch as an energy source. This interference leads to reduced growth, development, and survival of pest species. In the context of pest control, plant α-amylase inhibitors present a promising avenue for sustainable and eco-f...
The culture of little magazines in India came into being with the publication of Sabuj Patra in 1914 and became popular in other Indian languages in the 1950s. These “noncommercial” and ephemeral presses not only created the “modern” literary canon, which was chiefly “non-conformist”, but also defamiliarized the notion of the “text” through its material discontinuity. Little magazines in India served as the counter site of “new” literary movements and “unheard voices” from the margin. Thus, l...
Efficient coal extraction from underground mines is largely dependent on the stability of coal pillars, especially in the presence of geological discontinuities that weaken their strength. In Indian coalfields, traditional empirical formulas for pillar strength often neglect these discontinuities, focusing instead on pillar dimensions and coal strength. This study employs numerical simulations to evaluate the impact of multilayer weak bedding planes, placed at various positions within the pil...
A numerical simulation study is carried out for assessment of stability of coal pillars having dirt bands by varying its size and depths. Physico-mechanical properties of dirt bands including thickness and its position in pillar system are varied in the simulation study. Results of the simulation study are correlated with the available empirical approaches of pillar strength are validated with field observations. It is observed that the presence of weak dirt bands significantly influences the...
The education system has evolved through various discipline-wise segregation and policies over the years. The Ancient Greek and Roman civilisations practised a holistic knowledge system that merged the arts and sciences for the overall development of a child, similar to ancient Indian learning. After the European scientific revolution, the education system underwent strict division for pursuing various streams of knowledge. The re-emergence of multidisciplinary studies circles back to the cha...
In the present capitalist world system, the human approach to nature is utilitarian: it has been reduced to mere resources whose significance is equivalent to the surplus value it produces for the betterment of a section of mankind. This mechanistic view and commodification of nature is traced back to Western reductionist philosophies that deny agency to nature and the non-human and place humans at the top of the hierarchical ‘Great Chain of Being.’ The non-human turn in the Humanities, inspi...
Public spaces refer to those social spaces that are open and accessible to all, as well as spaces where the sharing of activities takes place. They help to create and strengthen external relationships, interactions, and social activities. Public spaces include parks, plazas, squares, gardens, beaches, waterfronts, streets, markets, libraries, community centres, sports facilities, and playgrounds. The design of any public space contributes to developing a sense of pride and belonging among the...
Urbanization in cities is striding at an incomparable and irreversible rate and is mostly driven by the population migration, which eventually imparts a significant pressure on the local environment, weather and climate in many ways. Therefore, the study on urban meteorology, climatology, and extreme weather is quite important in the current scenario as the country is evolving towards becoming an advanced economy. In this context, urban growth dynamics and future projection over Indian cities...
