Preparation, Categorization and Anticancer Study of Novel Bicyclic Compounds from Various Types for (Five and Six)- Membered Ring
Abstract: The characteristics of ring systems change in the presence of functional groups, but in some cases, elements that are considered functional groups can be classified within the same ring. Compounds that contain only carbon and hydrogen are called homogeneous rings, while those that contain other elements are called heterogeneous rings. The atom substituted in place of the carbon atom is referred to as a heteroatom. Generally, the heterocyclic atom is …

Symmetry Breaking in Mathematical Models: Bifurcation, Chaos, and Pattern Formation
Abstract: Symmetry breaking serves as a central organizing principle in the understanding of nonlinear systems across physics, biology, chemistry, and engineering. When a system transitions from a symmetric state to an asymmetric configuration, it often signals the onset of new structures, dynamic behaviors, or even chaotic regimes. This review explores symmetry breaking from the theoretical and mathematical perspectives of bifurcation theory, chaos theory, and pattern formation. We discuss how small parameter …

Role of Dermabrasion Assisted Tangential Excision in Paediatric Electrical Burn Wounds
Abstract: Early removal of necrotic tissue in deep electrical burns by tangential excision decreases scarring and promotes wound healing. Dermabrasion, traditionally used in dermatology for facial resurfacing and scar treatment, has shown promising results when applied to burn wound management. In burn care, dermabrasion serves as a form of blunt debridement, effectively removing superficial necrotic tissue without damaging underlying healthy structures. This technique helps reduce local inflammation and lowers the likelihood …
