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...
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...
There are laws which protect and prevent the teenage girls from working. But still in the developing countries like India, Bangladesh, etc. teenage girls coming from low socio-economic background work, to add to the family income. There is dearth of data regarding the ergonomic studies of the teenage girls working in the manual brick manufacturing units of the unorganized sectors in India. Ther...
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...
This study focuses on the mineralogical and chemical characterization of Mishan Formation marls from North East Ahvaz for brick production. Mineralogical and Geochemical studies were performed by XRD and XRF methods. Major minerals in marls are quartz, calcite, dolomite and the minor minerals are orthoclase, chlorite, and muscovite. Illite and montmorillonite are also present as minor minerals ...
We consider the thermodynamics of minimally coupled massive scalar field in 3+1 dimensional Taub-NUT background. The brick wall model of 't Hooft is used. When Schwarzschild like coordinates are used it is found that the usual radial brick wall cutoff parameter is required to regularize the solution. Free energy of the scalar field is obtained through explicit counting of states. It is found th...
