la caldera” is a high mountain lake located in sierra nevada, spain. for its position andcharacteristics it is considered as an important “sensor” for global changes. water samples were collectedduring the ice-free season in order to observe changes in the bacterial community structure. experiments were carried out complementing culture and culture-independent methods. strong variations of the ...

According to the five commentaries (Kim, Eells & Stiles, Rosenbaum, Molina & del Rio, and Gratier), the author tries to clarify the main cultural concept of utushi and ma. The work of utushi is discussed in its four aspects-in terms of affect, mimesis, reflection and cognitive change. Ma activates a proto-conversation that involves the tonus—a subtle sense of change on body sensation-in the the...

the rapid change of land use and land cover in the metropolitan area of tehran has influenced the distribution pattern of land surface temperature (lst). in this study, a spatial autocorrelation analysis is adopted to process the spatial-temporal changes of lst and normalized difference vegetation index (ndvi) in tehran during the period of 1987 to 2010. global spatial autocorrelation analysis ...

The current paper develops three different ways to measure the multi-period global cost efficiency for homogeneous networks of processes when the prices of exogenous inputs are known at all time periods. A multi-period network data envelopment analysis model is presented to measure the minimum cost of the network system based on the global production possibility set. We show that there is a rel...

Increasing concentrations of CO2 and other greenhouse gases in the atmosphere can be directly related to global warming. In terms of human health, because a major cause of increasing atmospheric concentrations of CO2 is the increased combustion of fossil fuels, global warming also may result in increases in air pollutants, acid deposition, and exposure to ultraviolet (UV) radiation. To understa...
