Holocene paleoclimate records from Greenland help us understand the response of the Greenland Ice Sheet and regional oceanic and atmospheric circulation systems to natural climate variability in order to place recent changes in a longer-term perspective. Here biogeochemical analysis of a lake sediment core from southeast Greenland is used to define changes in moisture balance and runoff during ...

We attempted to separate species of the genus Clusia according to the concentration of linear alkanes (C25 and C35), and the presence and diversity of terpenes in epicuticular wax extracts. We collected leaves of 15 Clusia species growing in mountain forests of Panama (Cerro Jefe 1007 m and Altos de Campana 800 m a.s.l.) and from cultivated plants at two lowland sites. Leaf surfaces were washed...

abstract in this study, we applied recently developed panel unit root and cointegration techniques to examine the long-run real income per capita and price elasticities for demand of electricity in selected middle east and north african (mena) countries using an annual data series from 1990 to 2011.our main finding from the panel analysis is that the demand for electricity is highly price elast...

abstract the theory of international tax competition suggests that governments attempt to attract mobile capital bases by undercutting the foreign capital tax rate. an analysis of the role that state capacity plays in tax policymaking under international pressures is, however, missing. the central contribution of our study is to highlight the importance of the interaction between state capacity...

Se evaluaron los biomarcadores en la fracción de hidrocarburos saturados (n-alcanos, pristano, fitano, terpanos y esteranos) un ensayo biorremediación 90 días con crudo extrapesado (10 ºAPI). Con base presencia una muestra compleja no resuelta (MCNR), deficiencia n-alcanos, fitano hopanos desmetilados (25-norhopanos), se determinó que el original está biodegradado. La detección pristano (más se...

in this paper a general view of the gini decomposition is presented. in order to decompose the gini coefficient into within group inequality, between group inequality and transvariation inequality of the iranian urban and rural areas, the 2006 and 2010  micro-data and dagum (1997) method is used. the results indicate that about 48 percent of the inequality in the country as a whole has been due...
