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...

In this study, we compared the cardioprotective effects of freshly crushed garlic vis-a-vis that of processed garlic. Two groups of rats were gavaged with respective garlic preparations while the control group received vehicle only. After 30 days, all of the rats were sacrificed and isolated the hearts were subjected to 30 min ischemia followed by 2 h of reperfusion. Both of the garlic preparat...

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...

abstract background: the aim of this study was to compare the efficiency of conventional slow sand filter with modified filter bed with crushed recycled glass in removing of turbidity and total and fecal coliforms from water resources.   methods: in this study efficiency of conventional slow sand filter and modified filter bed with crushed recycled glass during 4 months was compared and their p...
