Microstructural evolution and wear characteristics of equal channel angular pressing processed semi-solid-cast hypoeutectic aluminum alloys
This work investigated the microstructural evolution of Al-7Si-Mg alloy cast semi-solid using a cooling slope as well as conventional casting followed by equal channel angular pressing (ECAP) in a 120 die. Feed materials were prepared for ECAP by cooling slope casting and by conventional casting. The microstructure of the processed alloys extruded was observed by optical microscope and by transmission electron microscope, and their hardness and wear resistance were evaluated. After ECAP processing, the primary ?-Al phase tended to be elongated while the Si particles became fragmented and more nearly globular in shape and uniform in size than in the as-cast sample. The microstructure of the cooling slope-cast ECAPed samples was more homogenous than that of the conventionally cast ECAPed sample. The ?-Al phase sub-grains were refined to sub-micrometer sizes for samples cast by both methods after ECAP. The hardness of the cooling slope-cast ECAPed sample was also higher than that of the conventionally cast ECAPed sample. The wear resistance of the alloy improved after cooling slope casting and ECAP processing. 2014 The Authors. -

Microwave assisted structural engineering on efficient eco-friendly natural dye alizarin for dye sensitized solar cells application
The novel eco-friendly natural dyes, (9E, 10E), ? 9, 10-bis(2-(4-nitrobenzylidene) hydrazono) ? 9,10 dihydroanthracene-1,2-diol (NHA) have been synthesised using the one-pot microwave-assisted solvent evaporation method, and physicochemical characterizations were carried out using 1H NMR, 13C NMR, GC-MS, and FT-IR data. The photophysical properties of NHA dye were determined using experimental and theoretical techniques. The Stoke's shift shows a large bathochromic shift in polar solvents, which is due to the ??? * transition. The ground-state optimization of NHA dye was carried out using density functional theory (DFT) with the B3LYP/631 G level basis set. The HOMO-LUMO and energy band gap values computed from density functional theory and absorption threshold wavelengths are good agreement with each other. Further, the effect of TiO2 nanoparticles on NHA dye has been studied using spectroscopic and electrochemical techniques. It was observed that, NHA dye showed fluorescence quenching in the presence of TiO2 NPs, which is due to the photo induced electron transfer process. The apparent association constant of the interaction between NHA dye and TiO2 nanoparticles is also calculated using the Benesi-Hildebrand model. The Rehm-Weller relation infers that thermodynamically favourable electron transfer takes place between dyes and TiO2 NPs. Further, the solar cell was constructed using NHA dye as a sensitizer, and the photovoltaic conversion efficiency was found to be 1.16%. 2023 Elsevier GmbH -
Microwave-assisted extraction of phytochemicals
Microwave-assisted extraction (MAE) has emerged as a promising technique for the extraction of phytochemicals and has received substantial scientific attention in recent years. MAE involves the utilization of microwaves to heat the sample, which facilitates the release of bioactive compounds from the plant matrix. MAE offers several advantages over traditional extraction methods, including faster extraction times, higher extraction yields, and reduced solvent consumption. To improve the efficiency of the extraction process, research has concentrated on optimizing various parameters, including the extraction temperature, extraction time, and solvent type. Additional studies have investigated the effect of MAE on the chemistry and bioactivity of the extracted phytochemicals. Several classes of phytochemicals, including phenolic compounds, flavonoids, and alkaloids, have been successfully extracted using MAE. These compounds possess various biological activities, such as antioxidant, antimicrobial, and anticancer properties. Essential oils from aromatic plants have also been extracted using MAE, which is widely employed in the food, cosmetic, and pharmaceutical industries. Despite its many advantages, the major challenge in the application of MAE is the potential degradation of the extracted compounds due to the high-temperature and high-pressure conditions during extraction. Additionally, the cost of microwave equipment and the need for specialized expertise may stunt its widespread adoption. In diverse omics disciplines, MAE shows promise, notably for the development of analytical platforms for research in genomics, proteomics, metabolomics, and related subdisciplines. Nonetheless, more investigation is required to optimize the extraction conditions and guarantee that the chemical makeup and biological activity of the isolated phytochemicals are preserved.

Mid-infrared variability of ?-ray emitting blazars
Using data from the Wide-field Infrared Survey Explorer, we studied the mid-infrared (mid-IR) 3.4 ?m (W1-band) and 4.6 ?m (W2-band) flux variability of ? -ray emitting blazars. Our sample consists of 460 flat spectrum radio quasars (FSRQs) and 575 BL Lacertae (BL Lac) objects. On intraday time-scales, the median amplitude of variability (? m) for FSRQs is 0.04+0.03?0.02 and 0.05+0.03?0.02 mag in W1 and W2 bands. For BL Lacs, we found median ? m in W1(W2) bands of 0.04+0.01?0.02 (0.04+0.02?0.02) mag. On long time-scales, for FSRQs we found a median ? m of 0.44+0.28?0.27 and 0.45+0.27?0.27 mag in W1 and W2 bands, while for BL Lacs, the median values are 0.21+0.18?0.12 and 0.22+0.18?.011 mag in W1 and W2 bands. From statistical tests, we found FSRQs to show larger ? m than BL Lacs on both intraday and long time-scales. Among blazars, low synchrotron peaked sources showed larger ? m compared to intermediate synchrotron peaked and high synchrotron peaked sources. The larger ? m seen in FSRQs relative to BL Lacs on both intraday and long time-scales could be due to them having the most powerful relativistic jets and/or their mid-IR band coinciding with the peak of the electron energy distribution. BL Lacs have low power jets and the observational window too traces the emission from low-energy electrons, thereby leading to low ? m. In both FSRQs and BL Lacs predominantly a bluer when brighter behaviour was observed. No correlation is found between ? m and black hole mass. 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society -
Midwifery, Witchcraft, And Forensic Blindness: A Gendered Bioanalytical Inquiry Into Historical Practices
In Europe, going on witch hunts was a prevalent activity between the fourteenth and seventeenth centuries. Tens of thousands of people were tortured, executed, and burned in Germany, Italy, and eventually expanded to France and England; women made up three-quarters of the victims. The discovery of "the persecution of midwives as witches," which expanded throughout the Middle Ages and has drawn harsh criticism from historians of the 20th century, is one of the most startling disclosures. This paper examines the intersection between midwifery and witchcraft in Early Modern times, focusing on the risks that female midwives had to deal with in the field of work. Women who practiced the crucial profession of midwifery had their experiences impacted by the historical backdrop of extensive witch hunts and prosecutions. The paper seeks to offer a thorough understanding of the difficulties faced by midwives in balancing their vital role in birthing with the widespread suspicions of witchcraft by looking at the socioeconomic, cultural, and legal aspects. The paper also relies on the recent published work of Dr. Philippa Carter (2023). 2025, Green Publication. All rights reserved. -

Migrant minds, shifting selves: Navigating relationships and identity in internal migration
Human migration brings about changes in personal, social, cultural, political, and economic facets of life. This study examined the pre-migratory and post-migratory contexts of emerging adults in India to explore their connection to the existing relationships at migration origin, and upcoming interactions at migration destination. A qualitative method was used to capture the subjective experiences of emerging adults from middle SES, who migrated for education or employment reasons from rural, semi-urban, or urban areas. The migration experiences of these 1829 year-old emerging adults were analyzed through the lens of the social-cognitive model of transference. Semi-structured interviews of 17 internal migrants were conducted to learn about their experience residing away from home. Data analysis revealed schemas concerning significant others interfering with their new relationships at migration destination. Narratives of attachment, support, and conflict shaped their new relationship and self-perception at the migration destination. 2026 Elsevier Ltd. -
Migrants and homelessness: Life on the streets in urban India
There has been division and segregation of urban spaces and homeless migrants highlighting urbanization's contradiction. Despite being unseen, they make up a sizable portion of urban population. Being homeless in the city is a case of minimum citizenship, devoid of the right to the city, and is subject to ongoing violence. The expanding claim for the citizen's right to various public areas like pathways, pavements, and parks challenges their very existence on the streets and sidewalks (where they live). How do they perceive the hatred and disinterest of the wealthier classes? What uneasiness does the politics being played out in the name of locals against migrants create? The study will also examine the country's approach to the homeless, including their access to housing and sources of income. The Indian government has taken some steps to address homelessness among migrant workers, including providing financial assistance and setting up temporary shelters. Still, more needs to be done to address the root causes of this issue and ensure that migrant workers have access to safe and affordable housing, healthcare, and employment opportunities. This chapter plans to investigate issues, including how frequently migrants who are homeless experience violence and humiliation. It would analyze the macromicro paradox of the dynamics of migration. As the invisibleness and neglect of migrants frequently coincide with a widespread belief that migration must be reduced, this has obvious policy implications and implications for the inclusive growth model. In addition to that, this chapter has analyzed the country's policies on the homeless and their livelihood. The data was collected from secondary sources, and extensive study was conducted on various literature available from multiple databases. 2024 Elsevier Inc. All rights are reserved. -

Mind and Nature: Study on Mental Health, Nature Connectedness, Pro-Nature Conservation Behaviors and Geographical Green Cover among Indian Adults
For centuries the relation between mind and nature has been represented through literature, songs and cultural traditions. However with increasing urgency of the climate crisis and the corresponding growing distance between humans and nature, we find very limited scientific work exploring their relationship, which could perhaps help re-bridge the connection between the two. A significant, yet not directly observable, and often overlooked impact of the climate crisis is its impact on mental health. This study looks at this relationship in the Indian context, through a relatively unexplored perspective, by investigating the effects of nature connectedness (NC), pro-nature conservation behaviours (ProCoB) and geographical green cover (GGC) on mental health (MH) among middle-aged adults residing in India, and the existing inter-relationships. 180 middle-aged Indian adults, selected through purposive and snowball sampling, from across 21 states and 2 Union Territories (UTs), were administered questionnaires through a Google form. Their data was collected and scored, and the GGC was calculated for each state/ UT from the India State of Forest Report 2021. Correlation and Regression analysis were conducted on the scores using SPSS. A positive and statistically significant correlation exists between the variables NC, ProCoB and MH; NC, MH and GGC; and NC and ProCoB. NC and ProCoB predict MH. Gardening also predicts MH. The findings are new and contribute to the field of Environmental Psychology. It provides a scientific basis for the often romanticized relationship between man and nature as found in literature. It has great implications for the future, such as increasing awareness and understanding, and planning interventions to improve both environment and wellbeing. 2024 selection and editorial matter, Dr. Sundeep Katevarapu, Dr. Anand Pratap Singh, Dr. Priyanka Tiwari, Ms. Akriti Varshney, Ms. Priya Lanka, Ms. Aankur Pradhan, Dr. Neeraj Panwar, Dr. Kumud Sapru Wangnue; individual chapters, the contributors. -

Mind of a portfolio investor: Which strategies should I use as a basis for my investment decisions
It is smart for investors to plan for a drop that may be accompanied by a recession in the late stages of a bull market. The authors examine a variety of passive and active strategies, as well as their success in different crises. However, while choosing the best of strategies in the worst of circumstances, investors must be cautious in defining 'best.' It's critical to comprehend not only the long-term performance but also the whole cost of putting various preventive measures in place. The authors analyse popular strategies like technical analysis, fundamental analysis, relying on financial news, seeking professional advice, tips from trade experts, and self-intuition while making portfolios. Our findings indicate that every investment is unique. Some defensive methods will be more effective than others in each case. As a result, diversification across several viable strategies may be the wisest course of action. 2023, IGI Global. All rights reserved. -
