Direct red: a surgeon's story.

Two Important Issues Relevant to Torsional Response of Asymmetric 8-Story RC BuildingDesigned with Direct Displacement based Design Approach

Direct displacement based design (DDBD) is a conceptual framework that directly design a structure to achieve an expected performance level under specified seismic intensity. In this study, two important issues relevant to torsional response of mass eccentric 8-story RC building designed with DDBD approach are investigated. These issues are including the effects of unbalanced mass distribution ...

The story of the Red Cross.

Thank you for reading the story of the red cross. Maybe you have knowledge that, people have search hundreds times for their chosen books like this the story of the red cross, but end up in infectious downloads. Rather than enjoying a good book with a cup of coffee in the afternoon, instead they are facing with some malicious virus inside their computer. the story of the red cross is available ...

Removal of Direct Red 81 from Aqueous Solution Using an Acidic Soil Containing Iron (Case Study of Lahijan Soil)

Direct Red 81, a dye widely used in textile industries, is frequently detected dye in water resources. High costs, the formation of hazardous byproducts, and high energy costs restrict the use of some removal methods. Therefore, the main objectives of this research are the feasibility of using soil containing iron as a low cost adsorbent to remove (Direct Red 81) from aqueo...

Removal of Direct Red Dye 23 from Water and Wastewater Using S2O8 Oxidant Activated by UV Irradiation:An Investigation on the Operational Parameters

The photo-oxidative decolorization of Direct Red 23 (DR23), a textile dye which is suspected to be carcinogenic was investigated using peroxydisulfate activated by UV irradiation and heat in a batch photo-reactor at experimental conditions. A very simple analytical method, direct UV–vis spectrophotometric detection, was utilized for the progress of photo-oxidative decolorization of dye in aqueo...
