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...

A Critical Review of Natural Gas Flares-Induced Secondary Air Pollutants

by

Sonibare J.A.

General

Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO2, NO, and NO2 from “sweet” natural gas while “sour” gas emits SO2 in addition; incomplete combustion...

Analysis of tourism potential for Crete island, Greece

by

Mantzarakis A. and Nastos P.

General

To describe the tourism potential of an area, not only single meteorological parameters have to be taken into account, but also thermal sensation and people’s thermal comfort. The latter can be estimated by the use of human energy balance models and the derived thermal indices, which comprise all...

Watershed management with special emphasis on fresh water wetland: a case study of a flood plain wetland in west Bengal, India

by

Biswas M., Samal N.R., Roy P.K. and Mazumdar A.

General

The last few decades we have witnessed an enormous rise in awareness of the importance of wetlands. Mathura beel1 has been assumed to take the attention in recent years because of its ecological significance in terms of flood control, water purification, aquatic productivity, and microclimatic...
