Temporal and spatial scales of lake processes. Part 1: physical and ecological scales, non-dimensional parameters and flow regimes

by

Papadimitrakis I.

General

Scaling concepts, related to basic physical transport and mixing processes and other ecological aspects in lakes, are reviewed in an ecohydrodynamic perspective; the length and time scales as well as the non-dimensional parameters governing the various flow regimes and relevant to these processes...

Temporal and spatial scales of lake processes. Part 2: interaction of physical and ecological scales and application of scaling concepts to greek lakes

by

Papadimitrakis I. and Chioni A.

General

The temporal and spatial scaling concepts related to basic physical and ecological lake processes and the associated non-dimensional parameters that govern the various flow regimes, developed in lakes and reviewed in Part 1 of our companion paper (Papadimitrakis, 2011), are applied to lakes Pamvotis...

Removal of hexavalent chromium from electroplating wastewater by electrocoagulation with iron electrodes

by

Dermentzis K., Christoforidis A., Valsamidou E. and Lazaridou A.

General

The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial...

Under climatic change, soil microbial community and variables relating to N-cycle are modulated by changes in the upper limit temperature

by

Monokrousos N., Papatheodorou E.M. and Stamou G.P.

General

The effect of temperature increase and more specifically its upper and low level correlates on soil microbial biomass, activity and N-cycle variables was studied in a Mediterranean shrubland. Experimental manipulation succeeded in establishing three treatments which, in comparison with the monthly...

Plant biomonitoring: impact of urban environment on seasonal dynamics of storage substances and chlorophylls of Oleander

by

Meletiou-Christou M.S. , Banilas G.P., Bardisi C. and Rhizopoulou S.

General

In the present study seasonal changes of chlorophyll content and storage substances related to the metabolic response of the widespread, evergreen plant oleander (Nerium oleander) to air pollution were investigated. Mature leaves of oleander shrubs, grown at five sites of differing levels of air...

Application of sludge, organic solid wastes and yard trimmings in aerobic compost piles

by

Chazirakis P., Giannis A., Gidarakos E., Wang J.-Y. and Stegmann R.

General

The effects of different mixture ratios of sewage sludge (SS), organic fraction of municipal solid waste (OFMSW) and yard trimmings (YT) on the performance of composting process were investigated in this study. The high water content and the proper carbon/nitrogen ratio make sludge ideal for this...

Modelling the dispersion of harmful algal bloom (HAB) in the Thermaikos gulf (NW Aegean Sea)

by

Savvidis Υ.G, Patoucheas D.P., Nikolaidis G. and Koutitas C.G.

General

Coastal hydrodynamics are directly related to important environmental and ecological issues. This paper focuses on the study of harmful phytoplankton cells’ dispersion, after an episode of an algal bloom, based on mathematical modeling. The case of Thermaikos Gulf was used for the simulation. The...

Catchment scale hydrological modelling: A review of model types, calibration approaches and uncertainty analysis methods in the context of recent developments in technology and applications

by

Pechlivanidis I.G., Jackson B.M., McIntyre N.R. and Wheater H.S.

General

In catchment hydrology, it is in practice impossible to measure everything we would like to know about the hydrological system, mainly due to high catchment heterogeneity and the limitations of measurement techniques. These limitations and the need to extrapolate information from the available...

Statistical analysis of temperature changes in israel: an application of change point detection and estimation techniques

by

Gurevich G., Hadad Y,. Ofir A and Ohayon B.

General

The main goal of this study is to present and apply recently developed nonparametric change point detection and estimation techniques for confirming patterns of regional changes in temperature. Utilizing these methods, monthly temperatures (mean, mean maximum, mean minimum) and diurnal temperature...
