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...

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...

Bricks manufactured from dried sludge collected from an industrial wastewater treatment plant were investigated. Results of tests indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Increasing the sludge content results in a decrease of brick shrinkage, water absorption, and compressive strength. Results also showed that the br...

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...

Pure plays use the Internet as a market entry strategy and brick and clicks use the Internet as an alternate channel of distribution. Several theoretical frameworks are used to explore strategic and performance differences between business models. Results from a sample of 240 firms engaged in Internet-based consumer marketing suggest that brick and clicks are more effective than pure plays at u...

Difficulties for adaptation of wild rodents' colonies in the laboratory may hamper experimental studies. We describe the use of a hollow brick inside cages, to provide shelter and reduce stress of the animals. It facilitates the cleaning of cages, since the animals stay inside the brick while they are transferred to a new cage. This method was applied in a trial for adaptation of Oryzomys nigri...

A common decay scenario in old and new buildings was simulated: the effects on masonry structures of salt efflorescence or subefflorescence produced by the rise of saline solution. Eight different types of masonry wall each made up of a combination of different construction materials (brick, calcarenite and four types of mortar were combined as follows: pure lime mortar, mortar + air entraining...
