2D and 3D soil moisture imaging using a sensor-based platform moving inside a subsurface network of pipes
(2013)In this study a prototype sensor-based platform moving inside a subsurface network of pipes with the task of monitoring the soil moisture content is presented. It comprises of a mobile platform, a modified commercial soil ... -
Analysis of fault rupture propagation through uniform soil cover
(2009)This paper presents results from numerical simulations of the propagation of an active dip-slip fault rupture through a uniform soil layer covering the rigid bedrock. Following verification of the numerical methodology ... -
Antibacterial drugs in products originating from aquaculture: assessing the risks to public welfare
(2010)As aquaculture expands to meet human demand and compensate for pessimistic forecasts of fisheries catches, use of antibacterial agents to combat or forestall bacterial diseases is still a necessity, although effective ... -
Assessment of NDVI and agrometeorological indices for major crops in central Greece
(2002)Major agricultural crops such as vineyards and apples can be monitored by comparing normalized difference vegetation index (NDVI) with several agrometeorological indices. The agrometeorological indices used in this study ... -
Assessment of nutrients and heavy metals in the surface sediments of the artificially lake water reservoir Karla, Thessaly, Greece
(2015)In this research, the sediment quality of the recently reconstructed Lake Karla (central Greece) was evaluated by monitoring the nutrient loadings and heavy metal concentrations in 16 sites during the initial period of the ... -
Assessment of pressures and impacts on surface water bodies of the Mediterranean. Case study: Pamvotis Lake, Greece
(2013)The aim of the study presented in this article is to assess the ecological status of a surface water body in the Mediterranean using the methodological approach of Driver-Pressure-State-Impact-Response. Based on this ... -
Assessment of remotely sensed drought features in vulnerable agriculture
(2012)The growing number and effectiveness of Earth observation satellite systems, along with the increasing reliability of remote sensing methodologies and techniques, present a wide range of new capabilities in monitoring and ... -
Availability of Cu and Zn in an acidic sludge-amended soil as affected by zeolite application and liming
(2012)Purpose Acidic soils exhibit high trace element availability compared to neutral pH soils, and thus, when trace metals are added (e. g. due to sewage sludge application), measures should be taken to reduce their mobility. ... -
Basin-wide actual evapotranspiration estimation using NOAA/AVHRR satellite data
(2005)The present study elaborates on the estimation of actual evapotranspiration at watershed scale using mathematical models and remote sensing techniques. A water balance model was updated and used to simulate runoff from a ... -
Behavior of a seismically isolated bridge crossing a fault rupture zone
(2014)The effect of the fault rupture zone traversing a seismically isolated bridge is investigated utilizing a finite element model of a section of the Bolu Viaduct and a set of synthetic broadband strong ground motions simulated ... -
Bounding surface plasticity model for the seismic liquefaction analysis of geostructures
(2010)This paper presents the constitutive relations and the simulative potential of a new plasticity model developed mainly for the seismic liquefaction analysis of geostructures. The model incorporates the framework of critical ... -
Bridge health monitoring system based on vibration measurements
(2009)A bridge health monitoring system is presented based on vibration measurements collected from a network of acceleration sensors. Sophisticated structural identification methods, combining information from the sensor network ... -
The Byzantine wall paintings from the protaton church on Mount Athos, Greece: tradition and science
(2007)The present work is a study of the wall painting complex in the Protaton Church (1295) on Mount Athos, Greece. These paintings, high in artistic value, are themselves a monument-representative of the Macedonian iconographic ... -
Census of biodiversity in marine caves of the eastern Mediterranean Sea
(2015)Scientific information on the biodiversity of marine caves in the eastern Mediterranean is limited, especially when considering the extensively studied caves of the north-western and central Mediterranean. Aiming to enhance ... -
Characterization of methanogenic and prokaryotic assemblages based on mcrA and 16S rRNA gene diversity in sediments of the Kazan mud volcano (Mediterranean Sea)
(2008)The diversity of the methyl-coenzyme reductase A (mcrA) and 16S rRNA genes was investigated in gas hydrate containing sediment from the Kazan mud volcano, eastern Mediterranean Sea. mcrA was detected only at 15 and 20 cm ... -
Climatic impacts on the runoff generation processes in British Columbia, Canada
(2002)The potential impact of future climate change on runoff generation processes in two southern British Columbia catchments was explored using the Canadian Centre for Climate Modelling Analysis General Circulation Model ... -
Ecosystem modeling: Towards the development of a management tool for a marine coastal system Part I: General circulation, hydrological and dynamical structure
(2012)The semi-enclosed environment of Pagasitikos Gulf was the object of a holistic study during 1998-1999 following the appearance of mucilaginous events during summer. A major part of the INSEA project was the development and ... -
Ecosystem modelling: Towards the development of a management tool for a marine coastal system part-II, ecosystem processes and biogeochemical fluxes
(2012)Pagasitikos gulf is a semi-enclosed basin highly influenced both by anthropogenic activities (inflow of nutrients at the north and west parts) as well as by water exchange between the gulf and the Aegean Sea at its south ...
