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 seawater microbiological quality data in Greece from 1997 to 2006: association of risk factors with bacterial indicators
(2009)This study deals with the examination of quality of seawater bathing areas in Greece over a 10-year period and identifies risk factors for high bacteria indicator organism concentrations. Qualitative descriptive analysis ... -
Assessing heterogeneity of lesion enhancement kinetics in dynamic contrast-enhanced MRI for breast cancer diagnosis
(2010)The current study investigates the feasibility of using texture analysis to quantify the heterogeneity of lesion enhancement kinetics in order to discriminate malignant from benign breast lesions. A total of 82 biopsy-proven ... -
Attractor Divergence as a Metric for Assessing Walking Balance
(2010)Individuals with Parkinson's disease and the aged have a high prevalence of falls. Since an increase in the number of falls is associated with physical and psychological harm, it is prudent that biomechanical metrics be ... -
Environmental and economic evaluation of N fertilizer rates in a maize crop in Italy: A spatial and temporal analysis using crop models
(2012)Crop simulation models have the potential to assess the risk associated with the selection of a specific N fertilizer rate, by integrating the effects of soil-crop interactions on crop growth under different pedo-climatic ... -
Estimation of Ozone Trend in Central Greece, Based on Meteorologically Adjusted Time Series
(2012)Data referring to an approximately 8-year period (1999-2007) are analyzed in order to estimate the trend of the daily maximum hourly value of ozone concentration at the east coast of central Greece, where the summer ... -
Fish farming effects on local fisheries landings in oligotrophic seas
(2006)The effects of fish-farming on local landings in five regions of the Aegean and Ionian Seas (eastern Mediterranean basin) were analysed, together with certain parameters related to environmental changes and fishing fleet ... -
Genetic diversify among Balkan trout populations based on RAPD analysis
(2011)Random amplified polymorphic DNA (RAPD) markers were used to estimate the population structure and phylogenetic relationships among samples of the Salmo trutta complex that inhabit the Balkan Peninsula. Five random ... -
Melatonin secretion is impaired in women with preeclampsia and an abnormal circadian blood pressure rhythm
(2014)Non-dipping circadian blood pressure (BP) is a common finding in preeclampsia, accompanied by adverse outcomes. Melatonin plays pivotal role in biological circadian rhythms. This study investigated the relationship between ... -
Morphological variation between red mullet populations in Greece
(1998)Morphometric variation in 15 characters of the red mullet Mullus barbatus samples from seven Greek localities was examined using multivariate analysis. ANOVA, stepwise discriminant analysis and cluster analysis revealed a ... -
Performance of Myzus persicae (Hemiptera : Aphididae) clones on different host-plants and their host preference
(2003)The performance of eighteen clones of Myzus persicae (Sulzer) on pepper and tobacco plants at 20degreesC and L16:D8 and the choice of young adult apterae between tobacco and pepper leaf-discs were examined. The clones were ... -
Population structure and morphometric relationships of Paracentrotus lividus (Echinodermata: Echinoidea) in the South Aegean Sea
(2009)The gonads of the common sea urchin Paracentrotus lividus are a pricey gastronomic delicacy, and so the species is intensively harvested. Considering the recent collapse of its Populations in many Mediterranean areas and ... -
PROGNOSIS OF MAXIMUM DAILY SURFACE OZONE CONCENTRATION WITHIN THE GREATER ATHENS URBAN AREA, GREECE
(2014)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 ... -
Relationship between morphologic and genetic variation in red mullet (Mullus barbatus) populations from Greek Seas
(1998)Data derived from morphometric, allozymes and RAPD analyses were compared, in order to investigate the possible relationships between morphologic and genetic variation observed in seven Mediterranean red muller (Mullus ... -
Response of local and commercial tomato cultivars and rootstocks to Meloidogyne javanica infestation
(2011)Fifty two local Greek tomato (Solanum lycopersicum) cultivars and accessions and ten commercial nematode-resistant tomato cultivars and rootstocks were evaluated under controlled environmental conditions for resistance ... -
A simulation model of sustainability of coastal communities: Aquaculture, fishing, environment and labour markets
(2006)A bio-socio-economic model was developed to simulate (a) biological interactions related to traditional fishing, aquaculture, and the physical marine ervironment and (b) coastal labour market interactions and the regulatory ... -
Spatial monitoring of arsenic and heavy metals in the Almyros area, Central Greece. Statistical approach for assessing the sources of contamination
(2015)The purpose of this work was to provide information on As and heavy metals content in surface soils of the Almyros area, in Central Greece. A 3-year (2009-2011) research was conducted, in order to investigate the possible ... -
