Abstract-Physical adversities such as illness, obesity, accidents and psychological adversities such as emotional, social and play hazards and family and relationship adversities or personality threats like formation of unfavourable self-concept can lead to low self-esteem and low emotional intelligence. Adversity quotient is a score that measures the ability of a person to deal with setbacks, challenges, and problems. Focus on adversity quotient, as it is positively correlated with emotional intelligence. Focus on self-awareness, self-regulation and empathy. Today’s youths are tomorrow citizens.

Abstract-Drip irrigation is an advanced water delivery system designed to provide efficient irrigation by delivering water directly to the root zone of plants. 1This method involves a network of pipes, tubing, and emitters, ensuring that water is distributed evenly and precisely, minimizing water wastage. Compared to traditional irrigation methods, drip irrigation significantly reduces water consumption by preventing evaporation and runoff. Additionally, it promotes healthier plant growth by providing consistent moisture levels and reducing the risk of overwatering. This system is particularly beneficial for water-scarce regions and sustainable agriculture, offering advantages such as improved crop yields, reduced weed growth, and the efficient use of fertilizers. With its ability to optimize water usage and promote environmental sustainability, drip irrigation is a highly effective and cost-efficient solution for modern farming and gardening practices.

Abstract-Rainwater harvesting (RWH) is a sustainable method of collecting and storing rainwater for various uses, reducing dependence on conventional water sources. This paper discusses the potential for rainwater harvesting in buildings by calculating the amount of water that can be collected based on rooftop area, annual rainfall, and runoff efficiency. 1 The standard formula for estimating rainwater harvesting potential is outlined, considering key factors such as surface type and climatic conditions. Additionally, the benefits of RWH—including groundwater recharge, flood prevention, and cost savings—are highlighted. The study emphasizes the importance of designing efficient storage and filtration systems to maximize usability. Implementing RWH in urban and rural settings can contribute to water conservation and sustainability, making it a crucial component of modern water management strategies.

Abstract-Carbon dioxide (CO₂) is a sustainable, abundant, and non-toxic carbon feedstock, offering immense potential in organic synthesis. However, its thermodynamic stability and low reactivity necessitate innovative activation strategies. Recent advances have demonstrated CO₂’s utility in various transformations, including carboxylation, cycloaddition, hydrogenation, and carbonylation reactions. These processes enable the production of valuable compounds such as carboxylic acids, carbonates, carbamates, and heterocycles, often using transition metal catalysts, organocatalysts, or electrochemical methods. 1Catalytic systems such as metal complexes, N-heterocyclic carbenes, and metal-organic frameworks have been instrumental in overcoming the inherent challenges of CO₂ activation. Additionally, emerging approaches like electrocatalysis and photocatalysis provide sustainable pathways for CO₂ reduction and incorporation into organic frameworks. By converting a greenhouse gas into valuable products, CO₂ utilization not only addresses environmental concerns but also advances green chemistry. Ongoing efforts focus on improving reaction efficiency, selectivity, and scalability, paving the way for industrial applications and contributing to a circular carbon economy.

Abstract-Wastewater treatment is a crucial process for managing and purifying water contaminated by domestic, industrial, and commercial activities before it is safely discharged or reused. The treatment process involves multiple stages, including preliminary, primary, secondary, and tertiary treatment, each designed to remove solids, organic matter, harmful microorganisms, and chemical pollutants. 1Advanced techniques such as biological treatment, filtration, and disinfection further enhance water quality. Proper sludge management ensures the safe disposal or reuse of byproducts. Wastewater treatment plays a vital role in protecting public health, preserving ecosystems, and promoting sustainable water use. With growing concerns about water scarcity and pollution, innovative and efficient wastewater treatment technologies are increasingly essential for environmental sustainability and resource conservation.

Abstract-A Multiple Input Multiple output (MIMO)-fed circular slot antenna with wide tunable dual band-notched function and frequency reconfigurable characteristic is designed, and its performance is verified experimentally for high-frequency millimeter-waveband (MWB) communication 6G application s. The dual band-notched function is achieved by using an Ring-shapedresonator inserted the circular ring radiation patch and by etching a parallel stub loaded resonator in the MIMO transmission line. There are a wide range of approaches that have been advanced in the literature for adding reconfiguration to metamaterial devices all the way from the RF through the optical regimes, but some techniques are useful only for certain wavelength bands. A tunable range of almost one octave can be achieved if the R-SRR is loaded in its center with a slot. Furthermore, it has been demonstrated that a reconfigurable device can be achieved if a pair of shunt connected slots are introduced across the slots of the host MIMO. This feature, in conjunction with the tunability of a loaded R-SRR, has been used to achieve a reconfigurable and tunable structure. Finally, in order to demonstrate the potential 6G application of the proposed structure, a MWB antenna design with tunable notch band for Future 6G Communications. The design methodology has been validated through electromagnetic simulations.
