 Abstract

This study investigates the effect of partial replacement of natural coarse aggregate with recycled coarse aggregate (RCA) on the compressive strength and workability of concrete. With the increasing demand for sustainable construction materials, the utilization of construction and demolition waste has become a critical strategy for reducing the environmental footprint of the construction industry. In this experimental research, RCA was used to replace natural aggregate at three levels: 10%, 20%, and 30%, by weight. Additionally, silica fume was incorporated at a fixed dosage of 10% by weight of cement to enhance the pozzolanic activity and improve overall concrete performance. Concrete mixes were prepared using a fixed mix ratio of 1:2:4 (cement: sand: aggregate) with a constant water-cement ratio. For each replacement level, mixes were prepared with and without silica fume, resulting in eight different mix combinations. Standard 150 mm concrete cubes were cast, cured for 28 days, and tested as per IS 516:1959 for compressive strength. Slump tests were also conducted to assess the workability of the mixes. Results showed that compressive strength decreased with increasing RCA content in the absence of silica fume. However, mixes containing silica fume showed a significant improvement in strength, recovering up to 90% of the control mix's compressive performance. Workability slightly declined with RCA content but improved with silica fume addition. The study concludes that up to 30% RCA replacement, especially when combined with silica fume, can be effectively used in structural concrete, promoting sustainable practices without significantly compromising strength or workability

 Abstract

In this study, cobalt ferrite (CoFe2O4) nanocrystals were synthesized via a green, plant-mediated combustion route using Ocimum sanctum (Tulsi) leaf extract as a natural fuel and chelating agent. The methodology presents a sustainable alternative to conventional chemical synthesis by eliminating the need for toxic reagents, reducing energy consumption, and minimizing waste generation. The synthesized nanocrystals were systematically characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) analysis, and Brunauer-Emmett-Teller (BET) surface area measurements. XRD confirmed the formation of a single-phase spinel structure with average crystallite size around 25 nm. Morphological analysis revealed spherical and porous particles with a uniform distribution. The nanocrystals exhibited a band gap of 2.12 eV, indicating good absorption in the visible region. Photocatalytic activity was evaluated using methylene blue (MB) dye under visible light irradiation, where more than 91% degradation was achieved within 90 minutes. The photocatalyst showed excellent reusability and structural stability over four successive cycles. The enhanced photocatalytic efficiency was attributed to a synergistic effect of narrow band gap, high surface area, and efficient charge carrier separation. This study demonstrates a green and efficient approach for developing spinel ferrite nanomaterials for environmental remediation.

 Abstract

The concept of sugarcane migrant workers is relevant to understanding the major socio-economic problems faced by these workers after they migrate to the sugarcane cutting fields. The socio-economic issues include wages, income, and savings. And what are the before-migration and after-migration wage rates? Is the wage rate increasing or not? All such questions have arisen. This study identifies the socio-economic problems faced by sugarcane workers at the workplace. To estimate the income earned during the sugarcane cutting period., This paper is based on the primary data collected by questionnaires and field studies. The researcher used Microsoft Excel for data analysis, and the Paired samples test was used for hypothesis testing comparing the results before and after sugarcane migration.

 Abstract

Actinomycetes are a diverse group of Gram-positive bacteria known for their ability to produce a wide variety of bioactive secondary metabolites with significant medicinal properties. These microorganisms play a critical role in the development of antibiotics, anticancer agents, immunosuppressants, antioxidants, and anti-inflammatory compounds. Notably, Actinomycetes such as Streptomyces species have been the source of life-saving antibiotics like streptomycin, erythromycin, and vancomycin, which have revolutionized the treatment of infectious diseases. The ecological and evolutionary significance of Actinomycetes in producing these bioactive compounds for survival and competition further underscores their importance. Despite these advances made, several challenges such as difficulties in culturing, the rise of antibiotic resistance, and limited exploration of Actinomycetes in understudied environments limits its widespread use. This paper delves into the various therapeutic compounds produced by Actinomycetes, ranging from anticancer drugs like doxorubicin and bleomycin to immunosuppressants like rapamycin, demonstrate the far-reaching implications of Actinomycetes in modern medicine. A future research direction includes exploration of the underexplored species, optimizing metabolite production, and developing combination therapies. Overall, Actinomycetes remain an invaluable resource for combating emerging health challenges, and continued investment in research and innovation is essential to harness their full potential for medical and industrial applications.
