Trussed Bridges
Abstract: Trussed railway bridges offer a unique structural advantage by efficiently distributing the load between the truss members and the girder. In such designs, a significant portion of the load is carried by the truss members, which reduces the stress on the bridge girder itself. As a result, the girder in a trussed bridge can be constructed with a reduced thickness compared to bridges that lack a truss system. This optimization …

A Comparative Analytical Study on Gandhaka Ointment Prepared by Two Different Oleaginous Bases – As a Thesis Article
Abstract: Gandhaka (purified sulphur) is broadly used in Ayurvedic dermatological preparations, particularly in Malahara Kalpana (ointment formulations), due to its well-known antimicrobial and skin-healing properties. Although classical Ayurvedic texts, such as Rasa Shastra and Bhaishajya Kalpana, do not directly mention Gandhaka ointment, Rasatarangini by Acharya Sadanand Sharma describes four discrete methods for preparing Gandhaka Taila (sulphur-infused oil). In this study, the third method was selected to prepare Gandhaka Taila using two …
