Our paper explores the affinity between location and the registers of memory through the material specificities of moving image and the place of cinema using two recent moving image artworks, Reach and Maelstrom: The Return (2014), as case studies. Reach is an ‘environmental’ direct animation that enables a symbiotic conversation between artist and place through film’s agency as a sensitive and...
The National Wildlife Refuge system is a vital resource for the protection and conservation of biodiversity and biological integrity in the United States. Surveys were conducted to determine the spatial and temporal patterns of fish, macroinvertebrate, and crayfish populations in two watersheds that encompass three refuges in southern Indiana. The Patoka River National Wildlife Refuge had the h...
Viruses are important pathogens in both marine and fresh water environments. There is a strong interest in using bacteriophages as tracers because of their role as model viruses, since dissolved chemical tracers may not adequately describe the behavior of viruses that are suspended colloids. Despite a large number of studies that examined the transport of bacteriophages in the subsurface enviro...
[1] New methods of data collection and processing are developed to provide quantitative, reach-scale measurements of bedform transport mass within the tidally influenced Mississippi River. A multibeam swath profiler was used to collect daily bathymetry over a range of water discharges, and bed elevation changes induced by dune migration are measured. These values are coupled with bulk physical ...
A mass-balance approach was used to estimate in-stream processes related to inorganic nitrogen species (NH4C, NO2 and NO3 ) in a large river characterized by highly variable hydrological conditions, the Garonne River (south-west France). Studies were conducted in two consecutive reaches of 30 km located downstream of the Toulouse agglomeration (population 760 000, seventh order), impacted by mo...
The Yellow River (YR) covers three climatic zones including arid region, semi-arid region and temperate monsoon with frequent appearance of flow intermittence in the Lower (LYR) before 1999. Channel migration occurs frequently braided rivers, which is a major focus study geomorphology river dynamics. reach LYR featured by complexly spatio-temporal variation channel parameters owing to varying c...
Ice formation and related processes in rivers and lakes/reservoirs influence the operation of hydropower plants in cold regions. It is a matter of interest to the scientific community and hydropower operators alike how existing ice effects and problems will manifest themselves in a future changed climate. In this paper, we use different modeling results to investigate future freshwater ice cond...
The Guadiamar River (SW Iberian Peninsula) received a major toxic spill (6 hm) from a tailing pond in 1998 that defaunated 67 km of the main stem. Following early mud removal works, the fish assemblage was annually monitored at four affected sampling sites and one located in the upstream non-affected reach of the Guadiamar River as reference. Fish abundance and assemblage structure were analyze...
Functional reach (FR) significantly increases with additional sensory information from the fifth metacarpal surface of the dominant hand. The purpose of this study was to determine the relationship between the innervation density of the skin above the fifth metacarpal surface of the palm and the increase of FR with an additional light touch. The results show a moderate negative correlation betw...
