concentrations of lead (pb) were found in the shells of the oyster saccostrea cucullata and sediments in may 2010. samples were obtained at four sites on qeshm island, at three sites on hormoz island, and at three sites in lengeh port along the intertidal coast of the persian gulf of iran. the levels of pb in sediments and shells were analyzed by graphite furnace atomic absorption spectrophotom...

Since heavy metals are considered as one of the major pollutants threatening, the main goal of this study was to bring out the concentrations of Pb, Zn and Mn in the surface sediments off Bushehr in the Persian Gulf. For this purpose, after collection of samples, the concentrations of the three metals in surface sediments were measured through the atomic absorption. The results were compared wi...

We investigate whether superstitious beliefs held directly by only a fraction of the population affect market equilibrium. Using data from multiracial Singapore, we find that apartments whose unit numbers end with 8, an auspicious number for Chinese, are sold at 0.9% premium, whereas those that end with 4, an inauspicious number for Chinese, are sold at 1.5% discount.
