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...

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...

The composition process of the acousmatic piece Gazelle Rain Petals began with the construction of the elemental pitch and rhythmic modules – the organogeometric brick modules, as a musical metaphor to Dubuffet’s lithographic series Les Murs. These brick modules are 4-pitch series (tetrachords) that cover all possible pitch permutations to represent 4-sided geometric as well as organo-geometric...

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 ...

Concentration of 16 polycyclic aromatic hydrocarbons (PAHs) in eighteen baked bread samples using gas oven toasting were evaluated in this study. Samples were classified into the following categories: (1) bread baked from white wheat flour, (2) bread baked from brown wheat flour, and (3) sandwich bread baked from white wheat flour. Analysis was performed by GC-MS after Soxhlet extraction of the...

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 ...

OBJECTIVE To evaluate the residual effect of pyrethroids on the mortality rates of Anopheles in order to check their efficacy in indoor residual spraying in the Amazon Region, Brazil. METHODS The study was conducted in public housing units in the city of Belem, Northern Brazil, in 2003. Twelve houses were randomly chosen, three in each of the four established areas. Pyrethroids cypermethrin w...
