Increasing building constructions have become one of the fastest-growing drivers carbon emissions. Energy conservation and reduction in buildings increasingly crucial context global neutrality. This paper assesses annual total energy embodied ten most intensively used materials China, aiming to find potential CO 2 opportunities construction industry from a macroscopic perspective. The results s...

The Programmable Brick, a small autonomous computer with sensing and control abilities, has been a topic of educational research for almost two decades. The use of this tool has now reached beyond research projects through its commercial availability. However, high cost has strictly limited its audience to only well-funded schools and institutions. Can learning activities involving Programmable...

11 Abstract 12 13 Coating building materials with anti-graffiti treatments hinders or prevents spray paint 14 adherence by generating low energy surfaces. This paper describes the effect of coating 15 cement paste, lime mortar, granite, limestone and brick with two anti-graffiti agents (a 16 water-base fluoroalkylsiloxane, “Protectosil Antigraffiti®”, and a Zr ormosil) on the 17 dispersive comp...

A team of scientists from New Zealand and Indonesia undertook a reconnaissance mission to the South Java area affected by the tsunami of 17 July 2006. The team used GPS-based surveying equipment to measure ground profiles and inundation depths along 17 transects across affected areas near the port city of Cilacap and the resort town of Pangandaran. The purpose of the work was to acquire data fo...

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...

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...
