Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

the main objective in the present study was to assess the spatial variation of chemical and physical soil properties and then use this information to select an appropriate area to install a pasture rehabilitation experiment in the zereshkin region, iran. a regular 250 m grid was used for collecting a total of 150 soil samples (from 985 georeferenced soil pits) at 0 to 30, and 30 to 60 cm layers...

concentrations of heavy metals (ni, co, zn, cd, pb and cu) in the reservoir of shahid rajaeidam, one of the main water reservoirs in north part of iran, were determined using a differential pulse polarography(metrohm 797 va) and compared with the national and international specified maximum contaminant levels(mcl) for different purposes of water use. the results showed that concentrations of cd...

according to high height and weak tensile strength of materials in minarets, it is necessary to study the structural behaviour of minarets under earthquake loading. therefore nine historical brick masonry minarets in isfahan have been modelled and analysed by applying the nonlinear finite element method for two cases: 1) the whole minaret, and 2) only the outer shell. results show that all mina...

[1] We assess the relationship of ground-level fine particulate matter (PM2.5) concentrations for 2000–2001 measured as part of the Canadian National Air Pollution Surveillance (NAPS) network and the U.S. Air Quality System (AQS), versus remotesensed PM2.5 determined from aerosol optical depths (AOD) measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Multiangle Imagin...

English and Korean differ in how they lexicalize the components of motion events. English characteristically conflates Motion with Manner, Cause, or Deixis, and expresses Path separately. Korean, in contrast, conflates Motion with Path and elements of Figure and Ground in transitive clauses for caused Motion, but conflates motion with Deixis and spells out Path and Manner separately in intransi...

As urbanization progresses worldwide, earthquakes pose serious threat to livesand properties for urban areas near major active faults on land or subduction zonesoffshore. Earthquake Early Warning (EEW) can be a useful tool for reducing earthquakehazards, if the spatial relation between cities and earthquake sources is favorable for suchwarning and their citizens are properly trained to respond ...

It is still an open question if the auditory system, similar to the visual system, processes auditory motion independently from other aspects of spatial hearing, such as static location. Here, we report psychophysical data from a patient (female, 42 and 44 years old at the time of two testing sessions), who suffered a bilateral occipital infarction over 12 years earlier, and who has extensive d...
