The launch of B2B exchanges in brick and mortar industries has inspired the study of the potential impacts on business models of this shift from offline into online trade. Among market parties, intermediaries form a very interesting group, since electronic marketplaces could be seen as their direct competitors. We argue that the emergence of electronic marketplaces both creates opportunities an...

There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this paper, first, we show that the entanglement approach reduces to the brick wall model when we seek the maximal entanglement entropy. After that, the stability of the brick wall model is analyzed in a rotating background...

Brick monuments are one hallmark of emergent political complexity across much of mainland Southeast Asia during the first millennium AD. They first appeared in association with Indic statuary, large nucleated settlements, and the region's earliest states. Chronometric research in the Mekong delta on the earthen and brick wall that surrounds Angkor Borei (southern Cambodia) provides some of the ...

To study the impact of brick kiln emissions on plant growth and productivity, a study was conducted on various biochemical parameters of three main vegetables Brassica oleracea L., Phaseolus vulgaris L., and Solanum melongena L. cultivated in the vicinity of the brick kiln area of the Panzan village of district Budgam (J&K). Plants in the vicinity of brick kilns are direct recipients of emissio...

This work applies established analytical techniques of physical sciences to Irish brick in order to gather evidence of ceramic technologies, provenance and sources of raw materials. Petrographic microscopy, X-ray diffractometry and scanning electron microscopy with an energy dispersive Xray diffraction attachment were used to study the brick of Rathfarham Castle, Dublin, built c.1618, where cla...

Quantum field theory in the near-horizon region of a black hole predicts the existence of an infinite number of degenerate modes. Such a degeneracy is regulated in the brick wall model by the introduction of a short distance cutoff. In this Letter we show that states of the brick wall model with non zero energy admit a further degeneracy for any given finite value of the cutoff. The black hole ...

This project entitled " Implementation of the Laser Range Sensor BrickSick LMS 200" deals with the design and implementation of a sensor brick comprising the laser range sensor-LMS 200 manufactured by Sick as the major component of the brick for acquisition. This brick is expected to be an independent unit, capable of operating for various purposes. One of the major goals of devising such a bri...

Improving performance measures in the construction processes has been a major concern for managers and decision makers in the industry. They seek for ways to recognize the key factors which have the largest effect on the process. Identifying such factors can guide them to focus on the right parts of the process in order to gain the best possible result. In the present study design of experiment...

Two types of refractory bricks were used in reaction tests with slag from a production kiln for iron ore pellet production. Electron microscopy was used to characterize morphological changes at the slag/brick interface and active chemical reactions. Phases such as kalsilite, nepheline and potassium β-alumina form, in a layered structure, as a consequence of alkali metals migration in the brick....

For a brick apart from a few small graphs, Lovász (1987) proposed a conjecture on the existence of an edge whose deletion results in a graph with only one brick in its tight cut decomposition. Carvalho, Lucchesi, and Murty (2002) confirmed this conjecture by showing the existence of such two edges. This paper generalizes the result obtained by Carvalho et al. to the case of irreducible near-bri...
