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...
This study focuses on the radiological characterisation of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of (40)K, (226)Ra and (232)Th were, respectively, 644.1±64.2, 33.4 ± 6.4 and 42.2 ± 7.6 Bq kg(-1) in the clay brick samples and 179.7 ± 48.9, 55.0 ± 5.8 and 17.0 ± 3.3 Bq kg(-1) in the cement samples. The cal...
The objective of this study was to detect the fluoride level in the drinking water and the urine of habitants aged 16-55 years living in Inner Mongolia China. Furthermore, fluoride concentration of the brick tea infusion samples which were drunk by Mongolia herdsmen in everyday life living in SumuErga village of Ejin Horo Banner, Inner Mongolia China was also determined. A total of 117 particip...
We calculate the statistical entropy of a scalar field on the background of three-dimensional De Sitter space in terms of the brick wall method and finally derive the perimeter law of the entropy. ∗Electronic address: [email protected] 1 Entropy of black holes has an universal area law [1] and the entropy of the well-known Schwarzschild black hole satisfies the area law by means of thermal...
