Worldwide, vast amounts of waste are produced every year and most is sent directly to landfills or burnt, which has severe harmful impacts on the environment. Recycling materials considered visible solution protect Using scraps in concrete production a proper method for getting rid wastes, improving characteristics concrete, reducing consumption natural aggregates, can be used as cementitious t...

Brick making contributes significantly to the of supply materials for building industry. The majority brick production sectors, especially in developing countries, employ polluting and energy-inefficient technologies. Due increasing pressures on manufacturing firms improve economic performance growing environmental protection issues, sustainable clean is main concern makers. This paper consider...

BACKGROUND Brick tea type fluorosis is a public health concern in the north-west area of China. The association between SNPs of genes influencing bone mass and fluorosis has attracted attention, but the association of SNPs with the risk of brick-tea type of fluorosis has not been reported. OBJECTIVE To investigate the modifying roles of GSTP1 rs1695 polymorphisms on this association. METHOD...

WITH THE MANUFACTURING CAPACITY of thousands of wafers per week, and thousands of dies per wafer, today's silicon comes out of fab really fast—and furious—sporting device I/Os in the gigabit-per-second range. But it is increasingly going into high-volume and low-cost consumer electronic parts, exhausting the available time and money to test these parts. Little wonder that the 2003 International...

This paper proposes, for low buildings, an integrated wall structure of a brick-stem-insulating layer, which plays a major part in both heat preservation and force bearing. The research team has tested the thermal performance of the structure, the results of which are satisfying. To further study the force-bearing performance, the paper carries out compressive tests of specimens of different st...

The associahedron is a polytope whose graph is the graph of flips on triangulations of a convex polygon. Pseudotriangulations and multitriangulations generalize triangulations in two different ways, which have been unified by Pilaud and Pocchiola in their study of pseudoline arrangements with contacts supported by a given network. In this paper, we construct the “brick polytope” of a network, o...

This paper presents quality Clay-Brick selection process based on intuitionistic fuzzy multi criteria group decision making through grey relational analysis. Brick plays an important role in construction field. Intuitionistic fuzzy weighted averaging operator is used to aggregate individual opinions of decision makers into a group opinion. Six criteria are considered for selection process and t...

In this research, the authors assess the applicability of the SERVCON model to the e-commerce (e-service) environment in the context of student textbook purchases. Following a literature review, a survey was developed based on previous scales; items were modified to fit the e-commerce environment. The survey was administered to college students in business courses, and 281 usable responses were...

Water treatment plants produce a huge amount of sludge, which are ultimately disposed to the nearest water channel, leading harmful effects. This unmanaged wastewater plant sludge (WTS) results in social and environmental concerns. Therefore, utilization WTS construction activities can be viable option for management waste sustainable infrastructures. The main aim this study was investigate pot...
