ENVIRONMENTALLY FRIENDLY DETERGENT PRODUCTION

Hanifi Binici , Mustafa Dolaza, Mehmet Kara

Full Article

Water is one of the most important sources of life and is rapidly being contaminated by cleaning agents, such as detergent. Water pollution is a large threat to living things, and it is gradually making our world uninhabitable. Detergents, containers of phosphate, bleaches, and dirt separators are damaging the environment when they are poured into seas, lakes, and underground water storage. Every year, 50 million tons of detergent is used in the world. This massive amount is bringing a slow death by contamination to seas and lakes. Protecting the environment and the living things within it is one of our most important goals. In this study, the sunflower stalk is investigated as an alternative 'Greenpeace' detergent. The white-colored inner part of sunflower stalks is used to make environmentally friendly cleaning agents. Furthermore, these leftovers could contribute to the global economy because sunflower stalks remain in the field after sunflowers are gathered.

ISSUES IN THE DESIGN OF STEEL STRUCTURES FOR SEISMIC LOADING

S. Saileysh Sivaraja , T.S. Thandavamoorthy

Full Article

Earthquake forces mandate the absorption of energy imparted by it on the structures and steel is best suited for this. Multi-storey buildings are generally constructed in steel as framed structures. A ductile frame can undergo important inelastic deformations, localized in the neighborhood of sections with maximum bending moment. Considerable care is also needed in the design of steel structures to check failures due to instability and brittle fracture to ensure the development of full ductility and energy dissipation capacity under earthquake loading. Load and Resistant Factor Design (LRFD) is a design practice globally adopted to take care of the inelastic behavior of steel. Good workmanship is also an essential requirement in the construction of steel structures which has to resist severe earthquake forces. The paper highlights the issues involved in the design of steel buildings for seismic forces as well as the basic requirements of material characteristics.
