The aim of the present work was to characterize particulate matter (PM) and elemental carbon (EC) indoor and outdoor concentration levels in the Athens area and to examine the contribution of ambient air to the observed indoor levels. 24-hr simultaneous indoor and outdoor PM10 and PM2.5 measurements...

The aim of the present paper is to give a systematic and critical presentation of important existing analytical solutions for transient stream-aquifer interaction, which can be used to give answers to simple interaction problems or to verify mathematical models. Stream-aquifer interaction is the...

Particulate matter is one of the most important indoor air pollutants involved in a number of adverse health effects, such as premature deaths and increased mortality of infants and other parts of sensitive population. This paper focuses on investigation of metal substances of suspended as well as...

Rice husk carbon (RHC) has the ability to adsorb the dyestuff from aqueous solution. It may be useful low cost adsorbent for the treatment of effluents, discharged from textile industries. The effectiveness of RHC have been tested for the removal of colour from the wastewater samples containing...

In this study, the Bayesian approach is proposed to estimate the noise variances of Kalman filter based statistical models for predicting the daily averaged PM10 concentrations of a typical coastal city, Macau, with Latitude 22°10’N and Longitude 113°34’E. By using the measurements in 2001 and 2002...

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...

In this paper, three-dimensional numerical simulations are used to simulate the wind flow structure over coal stockpiles of a real configuration of a power plant. Two configurations are tested for various wind directions: the first one without representing the buildings and the second one with the...

Sorption of toxic metal ions (Ni2+, Cu2+ and Cd2+) from Hevea brasiliensis bark carbon (HBBC) was carried out at 30±1 °C under various experimental conditions. Effect of various process parameters has been investigated by following the batch adsorption technique at 30 +1°C. The percentage removal...

One of the main environmental impacts of pig farms are the swine odours emitted from the various stages of the process. The main cause of odour emissions from pig farms are the anaerobic processes in manure. Numerous factors affect odour emissions such as diet, manure management and manure age. The...

The main issue discussed in the paper is the application of qualitative analysis techniques when short data samples are available at the initial stage of experiments carried out to study behaviors of agricultural plant species under different environmental conditions. The proposed techniques are...
