Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

Background: Recent studies have shown that oxidative stress (OS) is the most important indicator in the pathogenesis of Alzheimer's disease (AD), but the results in previous studies are conflicting. This study aimed to assess the plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as DNA oxidative damage marker and total antioxidant capacity (TAC) in patients with AD versus control group. ...

Fluctuating asymmetry refers to small random deviations from perfect symmetry in bilaterally paired structures; it is thought to reflect an organism’s ability to cope with genetic and environmental stress during development and its utility as an indicator of such stresses is based on the assumption that perfect symmetry is an a priori expectation for the ideal state of bilateral structures. Flu...

Corporate sustainability is increasingly regarded as a management task. Thereby, especially environmental performance is becoming an important indicator. This paper addresses a measurement approach of evaluating environmental performance from an innovation perspective. Based on the insights from action research at a multinational corporation in Germany, we stress the importance of environmental...

Study of growth condition of medicinal plants under different water stress levels could be as an indicator for cultivation of drought resistance species in water scarce regions. Abiotic stresses such as drought stress are the main limitation factors in crop production and landscape development in arid or semi-arid regions such as Iran. Using drought resistant medicinal plants for developing lan...

Plant growth is affected by the osmotic stress as well as toxicity of salt in leaves. In order to study of salt stress effects on stomatal conductance and growth rate and relationship between them as wells osmotic and Na-specific effects on these traits, four bread wheat genotypes differing in salt tolerance were selected. Salinity was applied when the leaf 4 was fully expanded. Sodium (Na) con...

BACKGROUND: Oxidative stress has been reported to be higher in peritoneal dialysis (PD) patients than in normal subjects. The present study was conducted to test the hypothesis that oxidative stress is associated with technical survival in chronic PD patients. METHODS: We prospectively enrolled 97 chronic PD patients in a hospital-facilitated PD center. Plasma thiobarbituric acid-reactive subst...

This study proposes a method for improving the estimation of surface turbulent fluxes in surface energy balance system (SEBS) model under water stress conditions using MODIS data. The normalized difference water index (NDWI) as an indicator of water stress is integrated into SEBS. To investigate the feasibility of the new approach, the desert-oasis region in the middle reaches of the Heihe Rive...
