Influence of soil physicochemical and biological properties on the degradation and adsorption of the nematicide fosthiazate
(2006)The degradation and adsorption of the organophosphorus nematicide fosthiazate were investigated in nine soils with various physicochemical and biological characteristics. Fosthiazate was more persistent in acidic soils (pH ... -
Integrating Operational Hedging of Exchange Rate Risk in the Optimal Design of Global Supply Chain Networks
(2015)Supply chain network (SCN) design and operation is a strategic and value adding process for all synchronous companies. In the face of globalization, several issues should be contemplated and incorporated in decision support ... -
Lattice kinetic simulations in three-dimensional magnetohydrodynamics
(2004)A lattice kinetic algorithm to simulate three-dimensional (3D) incompressible magnetohydrodynamics is presented. The fluid is monitored by a distribution function, which obeys a scalar kinetic equation, subject to an ... -
Methodology for estimating seismic coefficients for performance-based design of earthdams and tall embankments
(2014)Following an overview of pertinent literature, this paper presents a new methodology for estimating seismic coefficients for the performance-based design of earth dams and tall embankments. The methodology is based on ... -
Mixed finite element formulations of strain-gradient elasticity problems
(2002)Theories on intrinsic or material length scales find applications in the modeling of size-dependent phenomena. In elasticity, length scales enter the constitutive equations through the elastic strain energy function, which, ... -
MULTIVARIATE STATISTICAL METHODOLOGIES FOR TESTING HYPOTHESIS OF LAND-USE CHANGE AT THE REGIONAL LEVEL. A REVIEW AND EVALUATION
(2009)Various models of land-use and land-cover change have been developed for better understanding of existing relationships and interactions between human and natural phenomena. Most of these models concentrate on human behaviour ... -
The nitric oxide-releasing derivative of ferulic acid NCX 2057 antagonized delay-dependent and scopolamine-induced performance deficits in a recognition memory task in the rat
(2010)Nitric oxide (NO) is considered as an intracellular messenger in the brain. its involvement in learning and memory processes has been proposed. The present study was designed to investigate the effects of the NO-releasing ... -
A novel flexible method to split feeding behaviour into bouts
(2009)Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the ... -
Performance evaluation of an automatic transfer line with WIP scrapping during long failures
(2007)We develop a model of a failure-prone, bufferless, paced, automatic transfer line in which material flows through a number of workstations in series, receiving continuous processing along each workstation. When a workstation ... -
Predicting demersal fish species distributions in the Mediterranean Sea using artificial neural networks
(2003)Predicting the occurrence of economically important demersal fish in a multispecies marine environment can be of considerable value to fisheries management and protection of biodiversity. Here, 2 predictive modelling ... -
Predicting Short-term Mortality in Patients With Pulmonary Embolism: A Simple Model
(2013)Background: The aim of the present study was to develop a simple prognostic rule that could classify patients with pulmonary embolism (PE) into categories of increased risk of 30-day mortality. Methods: One hundred patients ... -
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 ... -
Rarefied gas flow in a rectangular enclosure induced by non-isothermal walls
(2014)The flow of a rarefied gas in a rectangular enclosure due to the non-isothermal walls with no synergetic contributions from external force fields is investigated. The top and bottom walls are maintained at constant but ... -
Sample size estimation to substantiate freedom from disease for clustered binary data with a specific risk profile
(2013)Disease cases are often clustered within herds or generally groups that share common characteristics. Sample size formulae must adjust for the within-cluster correlation of the primary sampling units. Traditionally, the ... -
Satellite image classification using granular neural networks
(2006)The increased synergy between neural networks (NN) and fuzzy sets has led to the introduction of granular neural networks (GNNs) that operate on granules of information, rather than information itself. The fact that ... -
Stochastic analysis and prioritization of the influence of parameter uncertainty on the predicted pressure profile in heterogeneous, unsaturated soils
(2006)This article utilizes a Monte Carlo stochastic framework to investigate the influence on the mean and variance of the predicted mean pressure head profile of statistical assumptions regarding the parameters that enter the ... -
Terrorism and the effectiveness of security spending in Greece: Policy implications of some empirical findings
(2009)Greece has over the years faced serious security challenges from domestic as well as transnational terrorist activity. This paper examines empirically the effectiveness of counter-terrorism policy and particularly it focuses ... -
Trade efficiency and economic development: evidence from a cross country comparison
(2008)Economic theory suggests that development is enhanced through income growth, which is driven through increased trade. However, the empirical evidence of such a relationship most of the times is proved to be weak. In this ... -
A unified framework for pull control mechanisms in multi-stage manufacturing systems
(2000)This paper presents a unified framework for pull production control mechanisms in multi-stage manufacturing systems. A pull production control mechanism in a multi-stage manufacturing system is a mechanism that coordinates ... -
Vortex buffeting of aircraft tail: Interpretation via proper orthogonal decomposition
(2005)The proper-orthogonal-decomposition method is applied to particle-image-velocimetry (PIV) data to extract the most energetic flow structures of vortex-tail interaction. The reconstructed flowfields, in conjunction with ...
