Effects of Using Arsenic-Iron Sludge in Brick Making
Leaching of arsenic from brick manufactured from arsenic and iron sludge has been investigated in this study. TCLP result shows that leached metal concentrations are far below the regulated TCLP limits and the quantities of metal leached from sludge are less than those from dried sludge. The results of Atterberg limits tests of moulded sludge-clay mixtures indicated that both plastic index and ...
متن کاملBrick Generation
A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. The importance of bricks stems from the fact that they are building blocks of the matching decomposition procedure of Kotzig, and Lovász and Plummer. We prove that every brick except for the Petersen graph can be reduced to K4 or the prism by repeatedly applying a ce...
متن کاملStarting from scratch and building brick by brick in comprehension.
During narrative comprehension, readers construct representations of the situation described by a text, called situation models. Theories of situation model construction and event comprehension posit two distinct types of situation model updating: incremental updating of individual situational dimensions, and global updates in which an old model is abandoned and a new one created. No research t...
متن کاملBrick Manifolds and Toric Varieties of Brick Polytopes
In type A, Bott-Samelson varieties are posets in which ascending chains are flags of vector spaces. They come equipped with a map into the flag variety G/B. These varieties are mostly studied in the case in which the map into G/B is birational to the image. In this paper we study Bott-Samelsons for general types, more precisely, we study the combinatorics a fiber of the map into G/B when it is ...
متن کاملA Projection Model of Neutrosophic Numbers for Multiple Attribute Decision Making of Clay-Brick Selection
Brick plays a significant role in building construction. So we should use the effective mathematical decision making tool to select quality clay-bricks for building construction. The purpose of this paper is to present a projection model of neutrosophic numbers and its decision-making method for the selecting problems of clay-bricks with neutrosophic number information. The projection method of...
