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 ...

The splashing of a water drop is a fascinating phenomenon that results from a variety of complex interactions between the drop and the material it impacts. In general, the distribution of droplets of a splash depends on the drop size and velocity; the surface roughness, rigidity, and wetness; and the angle of impact. Given the number of factors involved, it is difficult to develop an analytical...

Historically, the success of automation has relied on two factors. The first is an understanding of the assembly process, first discovered and performed by hand, then captured, studied, and expressed in a technology. The second factor is the standardization of component properties. The standardization of component properties creates a marketplace in which many vendors can create components comp...

Unconventional raw materials are widely used in construction sectors; for example, phosphate sludge with the addition of rare earth elements (REE) when producing brick. The second example is nanostructured composite systems REE forming covers materials. This article studies flotation recovery REE, impact chlorides on distribution coefficient, and pH recovery. study proves possibility effective ...

Asphaltic concrete for pavement construction in India are produced by using crushed stone, gravels etc. as aggregate. In north-Eastern region of India, there is a scarcity of stone aggregate. Therefore the road engineers are always in search of an optional material as aggregate which can replace the regularly used material. The purpose of this work was to evaluate the utilization of substandard...

How will consumption patterns change when consumers move from brick-and-mortar to Internet markets? If consumers purchase more niche products online than at brick-andmortar stores, does this have something to do with the channel or is this solely due to selection effects: the types of consumers who decide to use the Internet channel or the types of products that consumers select to purchase onl...

Attracted by the numerous benefits of E-commerce, many traditional brick-and-mortar firms have embraced the Internet to supplement their business operations and have adopted the “click-and-brick” approach. Despite these changes, insufficient empirical research has been conducted on the impact of different firm types on financial performance. Based on the resource-based view, this study presents...
