Expansive soils are found abundantly in Ethiopia. This type of is weaker, having low strength and load resisting characteristics nature due to their difficulty volume change when it comes into contact with water. The such becomes swell saturated water shrinks during dry seasons. In civil infrastructure construction, soil either should removed or improved be used as foundation soil. Removing the...

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...

Red brick is one of the materials that still quite widely used in construction practice, because it easy to get and price relatively cheap. masonry wall a pair consisting binder (mortar) filler (red brick) known as masonry. Masonry generally provides durable construction, where constituent material, mortar quality, workmanship greatly affect durability overall construction. The installation inf...

Leaching of Arsenic from high Arsenic loaded iron oxide impregnated brick sands (IOI CBCM) was investigated using common household chemicals like common salt and soda ash, the industrial chemicals caustic soda and the phosphates used as fertilizers such as potassium hydrogen phosphate and TSP. Leaching by ordinary ground water was also investigated on the arsenic saturated iron oxide impregnate...

An investigation focused on the transformation and distribution behaviors of trace elements and natural radionuclides around a coal gangue brick plant was conducted. Simultaneous sampling of coal gangue, brick, fly ash and flue gas were implemented. Soil, soybean and earthworm samples around the brick plant were also collected for comprehensive ecological assessment. During the firing process, ...

Background Manual brick-manufacturing units in India engage a large number of female workers on a daily-wage basis for a period of 8 months per year. There are two groups of female workers in the brickfields: the brick molders and the brick carriers. These brickfields are mostly unorganized, and the workers are exposed to extreme conditions such as very high seasonal heat. The present trend of ...

This paper examines the effect of non-uniformmicrostructures on themacroscopic fracture properties of idealized brick and mortar composites, which consist of rigid bricks bonded with elastic–plastic mortar that ruptures at finite strain. A simulation tool that harnesses the parallel processing power of graphics processing units (GPUs) was used to simulate fracture in virtual specimens, whose mi...

This paper presents a novel interface element for the geometric and material nonlinear analysis of unreinforced brick-masonry structures. In the proposed modelling approach, the blocks are modelled using 3D continuum solid elements, while the mortar and brick-mortar interfaces are modelled by means of the 2D nonlinear interface element. This enables the representation of any 3D arrangement for ...
