Rural Building Base Isolation for Seismic Protection Using LRB and Friction Isolator
Abstract: Over 50% of the population of India, which is still developing, lives in unreinforced masonry buildings. Masonry constructions perform poorly and can collapse suddenly because they are susceptible to seismic loads and loads acting out of plane. Building collapse not only destroys public property but also claims life. It has been demonstrated that base isolation approaches for these types of structures are advantageous; in the event of seismic forces, they …

Liquid-Liquid Extraction Strategies for the Isolation of Bioactive Heterocyclic Compounds
Abstract: Liquid-liquid extraction (LLE) is a widely employed technique for the isolation of bioactive heterocyclic compounds from natural products, fermentation broths, and synthetic mixtures. The efficiency of LLE depends on several factors, including solvent selection, pH manipulation, salting-out effects, and temperature control. Conventional solvent systems, such as water-organic solvent pairs, are commonly used, while advanced strategies, including ionic liquids (ILs), deep eutectic solvents (DESs), ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE), …

Isolation and Characterization of Rhizosphere-Competent Indigenous Phosphate-Solubilizing Bacteria for Biofertilizer Applications
Abstract: Phosphorus (P) is an essential nutrient for crop growth and development. Low levels of P in soil is due to high reactivity of soluble P with calcium (Ca), iron (Fe) or aluminum (Al) that lead to P precipitation. Mineral phosphate (P) solubilization is an important activity of rhizospheric bacteria that contribute significantly to the plant growth and development in eco-friendly manner. Four potent phosphate solubilizers (PSB-2, PSB-3, PSB-4 and PSB-7), …
