Color paintings have much aesthetic value and historical importance. This study examined the color of east pillar Taiping Heavenly Kingdom’s Great Hall. The pillars in interiors ancient buildings were painted with a layer red lacquer. are valuable because they symbolize highest rank building’s hierarchy esteemed status owner. In this study, we investigated pigments, inorganic fillers, adhesives...

the flame propagation through a coal dust-air mixture in a spherical vessel was studied by means of a one-dimensional, arrhenius-type kinetics and quasi-steady model. the model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the single-stage reaction of the gas-phase combustion. effect of venting devices as safety idea and the radiation ...

the impacts of dust and sand storms (dss) on people, crops, livestock, infrastructure and health are well documented. data have accumulated on the deleterious effects of dust aerosols when they settle on plants. sand blasting of low growing plants is a common cause of failure in reforestation efforts. burial of plants by moving sands are also a cause of much damage. the physics of moving sand a...

Abstract. Impurities in polar ice do not only allow the reconstruction of past atmospheric aerosol concentrations but also influence physical properties ice. However, localisation impurities inside microstructure is still under debate and little known about mineralogy solid inclusions. In particular, general mineralogical diversity throughout an core specific distribution poorly investigated; i...

a total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. the higher values of ?18o are from metamorphic calcite and dolomite and lower ones are from granitic rocks. although the ?18o and ?13c values of calcite and dolomite in marble yield the highest values in the sangan deposi...

Equations are developed for the calculation of the simultaneous variations in trace element concentrations and radiogenic and stable isotopic compositions that occur during water-rock interaction. The equations are of general use for modeling chemical and isotopic variations in porous media and are applied here to the diagenesis of carbonate rocks and sediments. The variables which control the ...
