Compatibility issues of cement with water reducing admixture in concrete
Publication date: Available online 27 April 2016 Source:Perspectives in Science Author(s): A.K. Shrivastava, Munendra Kumar Multiple brand of cement and water reducing admixtures are available in the market, even though these cements and admixture comply with the respective codal provisions there performance are not same in the concrete for each and every brand of cement and water reducing admixture, even if quality and source of other ingredients of concrete is kept same. This has created a lot of confusion among the user about what type/brand of admixture is used with what type/brand of cement and what should be ...

Detrimental effects of tiny silt particles on large hydro power stations and some remedies
Publication date: Available online 26 April 2016 Source:Perspectives in Science Author(s): P.N. Darde Emergence of silt conscious designs of hydro power plants is an great challenge which calls for pooling the experiences of concerned. It also under lines the desirability of silt consciousness during investigations, design, operation, maintenance, refurbishment and upgrading. Due to inherent weak geology, rock instability, population explosions and deforestation, all rivers emanating from Himalayas carry enormous quantity of silt during heavy runoff of monsoon from June to September. Hydro Power stations located in H...

A one bath chemo-enzymatic process for preparation of absorbent cotton
Publication date: Available online 26 April 2016 Source:Perspectives in Science Author(s): A.S.M. Raja, A. Arputharaj, Sujata Saxena, P.G. Patil Cotton is the raw material for preparation of absorbent cotton. Raw cotton has to be subjected to scouring and bleaching processes for making it absorbent by removing the naturally present wax, protein and minerals in the fibre. The scouring is done at 115°C using alkali followed by bleaching at boiling condition using alkaline hydrogen peroxide solution. The effluent coming out of such processes contains high COD and BOD values. Due to the stringent environmental reg...

Video object extraction and its tracking using background subtraction in complex environments
Publication date: Available online 26 April 2016 Source:Perspectives in Science Author(s): Satrughan Kumar, Jigyendra Sen Yadav Background subtraction is an efficient way to localize and obtain the centroid of the connected pixels moving on the foreground despite the prior information of the scene. It is suitable under fixed camera arrangement, which incorporates many vision applications such as object tracking, human monitoring etc. However, the moving object extraction task becomes sophisticated and challenging due to some annoying factors such as local motion in background (waving tree, rippling water etc), camo...
