Due to the fact that water systems belong to critical infrastructure, diverse methods of its management assessment during crisis situations are applied. In these methods both technical aspects and human factors, that have an impact on safety of water supply to the recipient, are considered. Also...

Three-dimensional calculations were performed to simulate the flow around a cylindrical vegetation element using the Scale Adaptive Simulation (SAS) model; commonly, this is the first step of the modeling of the flow through multiple vegetation elements. SAS solves the Reynolds Averaged Navier...

Present investigation is an exertion to explore safe means of water for the community in the water scare region. In order to accomplish such goal origin of springs as well as chemical analyses of groundwater samples from different locations were carried out. Four zones are discovered on the basis of...

human health and the environment. The study aimed to explore the effects of exposure to pesticides on the liver functions and acetycholinesterase levels in serum (AChES) and red blood cells (AChER) of 100 male participating in agricultural work ranging in age between 20 and 60 year with mean age 37...

Onsite rainwater harvesting is an inexpensive water source for indoor use; it is also a sustainable water management practice, since it may contribute to the reduction of runoff volume and peaks, and to the control of non-point source pollution. The aim of this paper is to provide a method for...

Amoxicillin degradation with and without high frequency ultrasound waves of 2.4 MHz has been investigated. The concentration of amoxicillin was selected to be similar to that of outlet wastewater effluent concentration in pharmaceutical industry namely 50 and 100 ppm. The application of ultrasound...

The study examined the willingness of rural households to pay for sustainable management of community forests in Southwest Nigeria. The value elicitation format used was the dichotomous choice contingent valuation technique. The multistage random sampling technique was used in selecting 180 rural...

This work employs the environmental methodology of Life Cycle Assessment (LCA) in compliance with ISO 14040 and uses software SimaPro® 7.3.2 to compare the environmental impact in process production of flat plate and evacuated tube solar collectors. In addition, an economic analysis was performed...

Non-point sources pollution from highway runoff is among the most important reasons for surface and ground waters degradation. Atmospheric deposition, exhaust emissions, pavement wear and tire wear all have been found to be crucial pollutants in highway runoff. The most critical pollutants included...

In this work, we performed a detailed full cost accounting for 7 types of existing and planned municipal solid waste management facilities (sanitary landfills, anaerobic digestion, biodrying, incineration, aerobic mechanical and biological, material recovery and waste transfer stations) in Greece...

Thermogravimetric analysis combined with a mass spectroscopy detector was used to study the thermal stability of solid materials earmarked for processing by thermal desorption (for example during the amelioration of environmental damage). The objective of the study was to verify the applicability of...

The aim of the present study is to investigate the morphodynamic regime of the coastal area of Xylokastro (north coast of Peloponnese), in order to identify and evaluate the processes controlling its formation and evolution. Within this concept, a number of factors have been considered and evaluated...

This paper reviews the problem of foaming associated with the activated sludge process and its control using various physical, chemical and biological methods. Activated sludge process is widely used for treatment of every type of wastewater like industrial, domestic and municipal wastewater. This...

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...

In recent decades, there has been an increasing interest in the prognosis of maximum surface ozone concentrations due to the adverse effects on human health, animal population, agricultural productivity and forestry. The present study deals with the development and application of Artificial Neural...

This paper summarises the results of a survey carried out amongst the student population of one of the largest Greek Technological Educational Institutes. It explores attitudes toward the environment in general and then, more specifically, toward global warming and global warming-mitigation...

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...

This paper deals with the impacts of the current economic crisis on the temporal variation of urban traffic (during 2008-11) and consequently, the impacts on the urban air pollutant levels using as case study the city of Thessaloniki, Greece. The important temporal variations of the main economic...

The assessment of the air quality of indoor environment where people usually spend extended time periods, especially for sensitive population groups such as patients during their hospitalization, is of major importance. Ensuring a safe level of air quality in these indoor environment serves as an...

Simultaneous PM 10 and PM 2 .5 sampling was conducted for a six months period, at two sites of different characteristics. The first site was located in an urban background location in the North-Eastern part of GAA, affected by primary emission sources and particle transport from other parts of the...

The aim of this research is to study the behavior of different forest species in accordance with their ability to retain heavy metals on their leaves in order to select the most suitable species for urban and peri-urban use, which will contribute to the reduction of the continuously growing...

The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts.
