The temperature, feed rate, length of mass transfer zone, utilization factor and partial pressure are the parameters considered for fixed bed sorption of CO2 from N2/CO2 mixture. The breakthrough time relies strongly on the temperature and feed rate. The prolonged breakthrough and saturation times...

In the present study, the NO2 removal efficiency at concentrations of 3000 to 5000ppm was evaluated by nickel and platinum bimetallic catalyst supported on multiwalled carbon nanotubes (Ni-Pt/MWCNT) along with water vapor at different space velocity and temperatures. Morphological and structural...

Isotope mass balance in lake systems is strongly correlated with several climatic factors such as temperature, evaporation, precipitation and air moisture. On the other hand, the sedimentary budget of lake basins driven by climate, tectonic and/or human impact is an essential pool of environmental...

The present study simulates the flow and temperature fields in a street canyon caused by solar heating of road and building surfaces, in either calm and weak wind conditions. Six scenarios, formed by changing the sources of heat fluxes, the wind speed (0, 1 and 3 m s^-1) and direction (±), are...

Particles with aerodynamic diameters 1 μm (PM1) damage human health more severely than do coarse particles. In this study, PM1 number concentration, traffic flow, temperature and relative humidity in both a residential underground garage and at the entrance/exit, wind velocity at the entrance/exit...

Sulfur dioxide (SO2) emissions lead to negative environmental impacts and it is considered as an indicator for the larger group of gaseous sulfur oxides (SOx) in the air. In this paper, the dimethylamine (DMA) solution was used as the absorbent in a α-Al2O3 hollow fiber membrane contactor that is...

The production and use of biofuels such as ethanol have been the target of intensive research. One source of ethanol is corn, which is abundant in many countries. In producing ethanol from corn, an assessment of the environmental impact of the process is needed. This study intends to provide insight...

Tabriz is a large and industrial city in the north west of Iran which suffers from severe air pollution due to being surrounded by mountains. Considering lack of official reports about the levels of heavy metals in Tabriz air, two zones of the city were selected for measurement of heavy metals in...

This paper proposes one new attempt to formulate a mathematical approach to climate parameters in the context of their complex implications for tourist activities through the tourism climate comfort index (TCCI). This paper also aims to formulate an original and optimal mathematical correlation...

Water quality of Edion and Omodo Rivers were assessed chemically from March to October, 2010. The abstracted water samples were also subjected to bacteriological examination. The Rivers were each sampled at upstream and downstream locations. Twenty (20) physico-chemical characteristics which...

This paper aims to investigate students’ awareness regarding the factors that affect the environmental quality in university classrooms. For this purpose a questionnaire survey was conducted, in which 314 undergraduate students of the School of Primary Education, Aristotle University of Thessaloniki...

This paper studies the characteristics of the heat waves that were observed in Athens, Greece since 1951. A heat wave is detected when two temperature criteria are fulfilled at the city centre: the daily maximum temperature value is at least 37 oC and the daily average temperature value is at least...

The urban planning, the buildings and covering materials of all surfaces, the distance between adjacent constructions, the height and the orientation of the buildings are some of the factors which affect the sustainable conditions in the city. This paper presents a project that aims at investigating...

In this paper the influence of key meteorological variables in Penman evaporation method was explored. Monthly data over a 16-years period (1993-2008)were used from Thissio-Athens meteorological station. The climatic parameters of surface air temperature, relative humidity, wind speed and sunshine...

This study focuses on the estimation of thermal comfort conditions in a high alt. site (1455 m) in Apodotia (MA), Greece, by using the MLP neural network model. This estimation is based on the air temperature (t) and relative humidity (f) data of the middle (1078-1163 m) and of the low altitude...

This paper is focussed on the study of the air movement and temperature distribution inside refrigerating compartment of household frost-free refrigerators. It is well known that the correct air circulation and temperature distribution inside the refrigerated chamber are two of the most important...

The influence of microscale and mesoscale meteorology on the local scale variation of air temperature cannot be correctly simulated by the coarse resolution Global Climate Models. The scope of this work is to develop a hybrid dynamic-statistical downscaling procedure and quantify its predictive...

This research aims to investigate the bioclimatic conditions in different ground cover types in the greater Athens area, Greece: a major street with heavy traffic (MS), an adjacent pedestrian street (PS) with irrigated plants and an urban park. Four sites were selected: one in each of the streets...

The use of organic manures as amendments to improve soil organic matter level and long term soil fertility and productivity is gaining importance. The disposal of the great quantity of organic wastes produced by the municipal, agricultural and agroindustrial activities, is causing energetic...

In this study the vertical ozone profiles during summertime (June to August) of the MOZAIC (Measurement of Ozone and Water Vapor by Airbus in Service Aircraft) Project over the eastern Mediterranean airports of Heraklion and Rhodes in the Aegean Sea, have been analyzed in order to identify the major...

A field study on the impact of fireplace on the indoor air quality was carried out between 2004 and 2006, where two main contaminants, CO and particulate matters, were investigated in twenty seven randomly selected Irish houses.
