Eukaryotic cells have a self-organizing cytoskeleton where motors transport cargoes along cytoskeletal tracks. To understand the sorting process, we developed a system to observe single-molecule motility in a cellular context. We followed myosin classes V, VI, and X on triton-extracted actin cytoskeletons from Drosophila S2, mammalian COS-7, and mammalian U2OS cells. We find that these cells va...

unplanned urban development imposes significant pressure on land resources and land use structures and brings about many negative socio-economic and environmental consequences. therefore, comprehensive studies should be applied to support urban land use management in the world and especially in developing countries. in iran, like many other developing countries, urban development is fast and of...

In the United States, federal management agencies, such as the U.S. Forest Service and the U.S. Bureau of Land Management are required to assess the capability of land for future use. In addition, Arizona law now requires local jurisdictions to prepare comprehensive and general plans. Suitability analysis can be used for compliance with several elements of these plans. Here, a framework for lan...

Abstract Before planning the use of existing land resources for irrigation, it is necessary to determine their availability. The primary goal this research was examine Guder watershed's resource potential irrigation development and create a geo-referenced map these using geographic information system coupled with fuzzy logic. Irrigation suitability criteria such as slope, use, proximity water b...

Emotions change our perception of time. In the past, this has been attributed primarily to emotions speeding up an "internal clock" thereby increasing subjective time estimates. Here we probed this account using an S1/S2 temporal discrimination paradigm. Participants were presented with a stimulus (S1) followed by a brief delay and then a second stimulus (S2) and indicated whether S2 was shorte...

the present research aims to apply several approaches for suitability evaluation of lands under cultivation ofalfalfa and barley in chaharmil mechanized farming center, ardestan town, isfahan province, iran. climatic andsoil maps of the climate and soil data were provided in raster format. land evaluation carried out using maximumlimitation, parametric and multi-criteria (analytical hierarchy p...

Demand for information that can be used to manage loggerhead shrikes has recently increased because of concern over declining populations and loss of open, non-forested habitat. A previously-developed habitat model was modified to predict shrike habitat quality on Fort Riley Military Reservation (FRMR) in Kansas. Shrike habitat suitability indices were calculated based on the amount of potentia...
