Seismic Analyasis and Design of Proposed Elevated Intz Type Water Tank at Sbpcoe Indapur

Elevated water tanks are one of the most important lifeline structures in earthquake prone regions. The major cities and also in rural areas. Theelevated water tank is an integral part of water supply scheme, these structure has large mass concentrated at the top of slender supporting structures are especially vulnerable to horizontal forces due to earthquake. All over the world, the elevated water tanks were collapsed or heavily damaged during the earthquake because of unsuitable design of supporting system or wrong selection of supporting system underestimated demand or strength. So it is very important to select propersupporting system and also need to study the response of elevated Intz water tank to dynamic forces by both equivalent static or dynamic method and to find out the design parameters for seismic analysis

Biopolymer-Based hydrogels for agriculture applications: Swelling behavior and slow release of agrochemicals

Hydrogels are cross-linked polymers that can absorb and hold largeamounts of water and aqueous solutions due to the presence of hydrophilic functional groups in their 3D network. These materials also serve as vehicles of different active compounds because they can regulate their release rate. Because of such properties, hydrogels are currently used in many areas including agriculture, mainly as water retention agents for soil conditioning, and as carriers of agrochemicals for their slow or sustained-release. However, most of the hydrogels currently available on the market are based on polyacrylamide and acrylate derivatives, which means that they are not completely biodegradable, i.e. are considered as potential soil contaminants and present certain degree of toxicity. In this context, the development of biodegradable hydrogels for their use in agriculture is gaining interest worldwide. Biopolymers such as chitosan, cellulose, alginate and their derivatives are being explored due to their biocompatibility, biodegradability and low cost. Briefly, in this chapter, recent studies on biopolymer-based hydrogels for their use in agriculture are discussed in terms of their synthesis, swelling behavior, as well as their uses for slow and controlled release of agrochemicals.Fil: Tomadoni, Bárbara María.
