Quenched phosphorescence detection is a sensitive detection method recently introduced in capillary zone electrophoresis. It is based on the dynamic quenching interaction of the analytes (quenchers) with a phosphorophore, 1-bromo-4-naphthalenesulfonate (BrNS), present in the separation buffer. In this study, it is shown that this detection method can also be used in cyclodextrin-based electroki...

This study investigates the land surface temperature (LST) distribution from thermal infrared data for analyzing the characteristics of surface coverage using the Vegetation-ImperviousSoil (VIS) approach. A set of ten images, obtained from Landsat-5 Thematic Mapper, between 2001 and 2010, were used to study the urban environmental conditions of 47 neighborhoods of Porto Alegre city, Brazil. Por...

An Empirical Study of the Relationships between CO2 Emissions, Economic Growth and Openness This paper investigates the existence of the environmental Kuznets curve (EKC) for carbon dioxide (CO2) emissions and its causal relationships with economic growth and openness by using time series data (1971-2006) from China (an emerging market), Korea (a newly industrialized country), and Japan (a deve...

This study investigates whether the environmental Kuznets curve (EKC) relationship is supported for a measure of biodiversity risk and economic development across the United States (US). Using state-level data for all 48 contiguous states, biodiversity risk is measured using a Modified Index (MODEX). This index is an adaptation of a comprehensive National Biodiversity Risk Assessment Index. The...

This study explores the ecological indicators relevant to long-term sustainability by the food-energywater nexus among BRICS (Brazil, the Russian Federation, India, China, and South Africa). The sustainability issue arises with the EKC (environmental Kuznets curve) hypothesis and biodiversity that require proper resource allocation to provide food security among the BRICS countries. This study ...

The environmental Kuznets curve (EKC) hypothesis assumes there is an inverted U-shape relationship between pollution and income per capita, implying improvement in quality when a growing economy reaches high level of economic development. This study evaluated empirically the existence Greenland for period 1970–2018. Using autoregressive distributed lag (ARDL) approach, results show evidence U-s...

A local outbreak of epidemic keratoconjunctivitis (EKC) caused by human adenovirus type 8 (HAdV-D8) occurred in Kawasaki city, Japan in July-August 2011. Since the cases were sporadic in nature, the source of the infection could not be identified. The results of PCR analysis and the appearance of cytopathic effects in the samples indicated that 22 patients were positive for HAdV. The mean a...

Using Environmental Kuznets Curve theory, this article examines the EKC effect of economic growth, energy intensity and carbon emission intensity on total quantity of carbon emission under the constraint of energy-saving policy. Optimizing energy-consuming structure and decreasing energy-consuming intensity can incline carbon emissions intensity and slow down the increasing speed of carbon emis...

Epidemic keratoconjunctivitis (EKC) is a severe eye infection caused mainly by adenovirus type 8 (Ad8), Ad19, and Ad37. We have shown that the EKC-causing adenoviruses use sialic acid as a cellular receptor on A549 cells instead of the coxsackie-adenovirus receptor, which is used by most adenoviruses. Recently, Wu et al. (Virology 279:78-89, 2001) proposed that Ad37 uses a 50-kDa protein as a r...
