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...
Building classification is pivotal in various applications, such as urban planning, navigation, and campus management. This paper presents a novel approach for building classification using a transformer-based model. The proposed framework integrates convolutional neural networks and selfattention mechanisms, leveraging the capabilities of both local and non-local feature extraction. We have curated a diverse dataset by taking images of various buildings at the National Institute of Technolog...
People are more concerned about their health these days, and the accuracy of medical information has come into focus. Since medical data frequently contains missing values, the field of medical data imputation has recently seen a surge in activity. This work presents a method that combines data imputation and clustering optimization to handle these challenges. Missing values are filled using matrix factorization with Truncated Singular Value Decomposition (SVD), which estimates the missing en...
Mammography is crucial for detecting breast cancer, but noise can hinder accurate interpretation. This paper proposes a two-stage hybrid de-noising algorithm for digital mammograms. First, the Adaptive Modified Median Filter (AMMF) removes noise, and then Guided Filter (GF) is applied to preserve edges and details. Experiments on Mammographic Image Analysis Society (MIAS) dataset show the filter effectively removes salt-and pepper noise. Performance is evaluated using metrics like Mean Square...
Agriculture robot has emerged as a transformation field, promising to revolutionize traditional farming practices by enhancing efficiency, productivity, and sustainability. Weed free condition during the critical period of crop is absolute important for getting maximum yield. Weeds can be effectively managed by physical, chemical, and biological method. Among all those methods, hand weeding is an effective method of weed management. At the same time, increased labour wages and unavailability ...
Leaf protein contains up to 48% soluble proteins but is difficult to extract using conventional methods due to rigid cell wall structure. Therefore, mechanical pretreatment could be a better option to increase the protein yield. Meanwhile, Moringa oleifera leaves are a rich source of protein and contain an adequate amount of amino acid (AA). Hence, moringa leaf flour was subjected to ball milling (BM) for 1, 3, and 5 h and measured the effect of BM on the protein yield, structural and functio...
Among different legume proteins, guar germ proteins is underexplored. So, isolated guar germ proteins were treated with cold plasma (CP) to understand the impact on nutritional, functional properties, and rheological behaviour. Moderate CP treatment improves digestibility and has a minor impact on amino acids. The higher applied voltage could induce the formation of protein aggregates, as observed in the SDS-PAGE model. At the same time, noticeable changes in functional properties were identi...
