The relationships between the annual variability of the Aleppo pine tree-ring widths and the variability of the main climatic parameters in the Attica basin are analysed in the present study for a 45-year period (1959-2003). The Principal Components Analysis was applied to the times-series of the...

Chlorine was accepted as an effective disinfectant for drinking water in early 1900s. Because of chlorination, chlorine has dramatically reduced the incidence of waterborne diseases. An unwanted side effect is the formation of harmful by-products upon chlorination. The most significant group of...

One of the most favorable and cost-saving methods to counteract water quality deterioration in a harbor basin is the use of flushing culverts, which reduce flushing times and avoid areas of low flow and eddies formation. In the present paper, results of experiments carried out in a 2-D facility in...

The waste to renewable energy source has become a priority in the wastes treatment field. The research goal is not only the wastes destruction but also a better thermal energy recovery from the processes. The municipal solid waste presents a high heterogeneity degree from the dimensional point of...

Vehicle emissions constitute the main source of atmospheric pollution in modern cities. The increasing number of passenger cars, especially during the last decade, resulted in composite traffic problems with serious consequences on emissions and fuel consumption. This project was carried out in the...

A teleconnection pattern has been identified between Eastern Mediterranean and Northwestern Europe in the geopotential fields of the upper troposphere (hereafter will be referred to as EMP) during winter and it seems to play significant role in the large-scale atmospheric circulation over...

Μany applications in water quality management have a common key water quality parameter, dissolved oxygen, resulting to the critical role of aeration. On the other hand, in municipal and industrial wastewater, especially where aeration is applied, the presence of volatile organic compounds (VOCs)...

The Olympic Rowing and Canoeing Center constructed at Schinias, accommodated the rowing and canoe – kayak sprint competition of the 2004 summer Olympic Games. This paper presents the results of a study which aimed at assessing the water quality characteristics, regarding microbial pollution, of the...

A simulation is presented of the operation of brackish karst springs with the MODKARST deterministic mathematical model. Through this simulation, major issues regarding the operation mechanisms as well as the sustainable development of the springs are addressed and analyzed. The particular case...

A pioneer effort is made in this study to carry out an experimental determination of shrinkage characteristics of neem (Azadirachta indica A. Juss) wood on its linear, volumetric, and coefficient values with the hope of ascertaining its utilization potential as timber. Three study locations were...

In the present study, the spatial and temporal surface air temperature variability for the Northern Hemisphere has been examined, for the period 1900-1996. Factor Analysis has been applied to 5o Latitude x 10o Longitude grid box data covering the area from almost the equator to 70o N. These data are...
