Inspired by people’s strong memory for visual-spatial paths (e.g., commuting paths), we present in this paper an introductory exploration of the use of these paths for memorable, strong mobile authentication. In a preliminary study, we evaluated several lowfidelity representations for encoding relatively strong (~20 bit) secrets as visual-spatial paths: a 2D birds-eye view, a 3D thirdperson vie...

Department of Earth and Environmental Science Environmental Geochemistry Laboratory The University of Texas at San Antonio ________________________________________________________________________ Abstract Century-long disposal of sewage sludge in Mitchell Lake at San Antonio, Texas has resulted in hyper-eutrophic conditions and an excess accumulation of toxic metals in the lake system. To ident...

The Zerebar Lake is a shallow freshwater lake located in the northwestern Iran. The lake is surrounded by three human activities: agriculture, tourism and dam. The present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the Zerebar Lake (2) If phytoplankton communities, as the indicator, are correlated with the human activities. Water samples wer...

Hydrographically Bolivian Poopó Lake is located in the basin of Desaguadero River and it has over a dozen main tributary rivers and other smaller rivers with lower flow. The mine water discharge from the abandoned and current mining activities polluted these rivers by carrying heavy metals, dissolved and suspended solids which in turn polluted the Poopó Lake which is considered as an important ...

BACKGROUND Health impact assessment (HIA) has emerged to identify those activities and policies likely to have major impacts on the health of a population. METHOD In this research, qualitative method was applied to identifying health determinants that urban man made lake affect on them, formatting and weighing the hierarchy of the factors, calculating AHP, and Technique for Order Preference b...

Maharloo Lake is one of the salty lakes located in the southeast of Fars province, Iran. Presence of salt domes has a significant role in its salinity. Magnesium-sodium chloride and sodium sulfate are dominant salts of the lake. Due to the drying up of lake, widespread lands surrounding the area are exposed to secondary salinity. It seems necessary to investigate the changes to find salinity le...

Present study aims to unravel the hydro geochemical interaction of sediment and water of Saheb bandh lake, West Bengal, India with an emphasis on heavy metal assessment. Lake water belongs to Ca2+–HCO3− type hydro geochemical faces and water-rock interaction primarily controls the lake water chemistry. Based on different Hydro chemical characteristics it is suggested that silicate weathering is...
