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 ... -
Cross-transmission of multidrug-resistant Acinetobacter baumannii clonal strains causing episodes of sepsis in a trauma intensive care unit
(2008)OBJECTIVE. To investigate the mode of transmission of imipenem-resistant Acinetobacter baumannii strains causing episodes of sepsis. SETTING. A 7-bed trauma intensive care unit (ICU) in an orthopedic hospital in Greece. ... -
Decomposition of NO on Pd and Ir. Comparison with Pt and Rh
(1996)The unimolecular decomposition of NO has been examined on Pd and Ir and they are compared with the corresponding reactions on Pt and Rh. The runs were carried out in a differential now reactor, at pressures from 0.01 to 5 ... -
Dependence of contact area on the resolution of fractal interfaces in elastic and inelastic problems
(2011)Purpose - The purpose of this paper is to investigate the influence of the resolution with which interfaces of fractal geometry are represented, on the contact area and consequently on the contact interfacial stresses. The ... -
An EPR study of Cu adsorption by clinoptilolite from Cl-, NO3 and SO42- solutions
(2008)The concentration and the type of Cu2+ species adsorbed on a natural zeolite (Clinoptilolite) was measured and studied by using Electron Paramagnetic Resonance Spectroscopy (EPR). The EPR results together with macroscopic ... -
Fluid Flow at the Nanoscale: How Fluid Properties Deviate from the Bulk
(2013)The studies of fluid flows have been lately transferred to a significant extend at the micro- and the nano-scale, since there is increasing interest in applications that could make possible the construction of systems from ... -
A genetic algorithm solution to the design of slat-type shading system
(2006)This article presents a technique for the design of slat-type blinds based on the their relative light intensity distribution under a uniform light source. The technique offers a new approach using a genetic algorithm in ... -
Nucleation, growth and detachment of neighboring bubbles over miniature heaters
(2008)This work investigates how simultaneous CO2 bubbles desorb from water and n-heptane when these liquids become supersaturated with dissolved CO2. Supersaturation is imposed locally by a miniature heater so bubbles grow at ... -
Recombination in primeval genomes: A step forward but still a long leap from maintaining a sizable genome
(2004)A stubborn question in early molecular evolution is how to sustain the "minimum" informational length required for the basic features of life with a putative low-copying fidelity RNA polymerase ribozyme. Proposals to ... -
SP-Dock: Protein-Protein Docking Using Shape and Physicochemical Complementarity
(2013)In this paper, a framework for protein-protein docking is proposed, which exploits both shape and physicochemical complementarity to generate improved docking predictions. Shape complementarity is achieved by matching local ... -
Strength evalution of retrofit shear wall elements with interfaces of fractal geometry
(2002)In the present paper structures involving rough interfaces, with irregularities of all scales, are simulated with the help of fractal Geometry. More specifically, the approach followed is the multilevel hierarchical approach. ... -
Study of the Residual Strength of an RC Shear Wall with Fractal Crack Taking into Account Interlocking Interface Phenomena
(2013)In the present paper, the postcracking strength of an RC shear wall element which follows the construction practices applied in Greece during the 70s is examined by taking into account the complex geometry of the crack of ... -
Sustainable production zoning for agroclimatic classification using GIS and remote sensing
(2009)Agriculture is a primary productivity sector which is highly dependent on environmental conditions. The agroclimatic potential of agricultural areas has to be assessed in order to achieve sustainable and efficient use of ... -
Transport properties of liquid argon in krypton nanochannels: Anisotropy and non-homogeneity introduced by the solid walls
(2009)In this work we calculate the transport properties of liquid argon flowing through a nanochannel formed by krypton walls. Non-equilibrium Molecular dynamics (NEMD) simulations are performed assuming flow conditions ... -
Wedge indentation of elastic-plastic layered substrates: Designing against contact-induced plasticity
(2009)The present paper investigates the indentation of plastically graded substrates by wedge indenters. Substrates made of graded materials are often encountered in nature or are artificially produced. The variation of the ...
