The effect of infinitesimal damping on the dynamic instability mechanism of conservative systems
(2008)The local instability of 2 degrees of freedom (DOF) weakly damped systems is thoroughly discussed using the Lienard-Chipart stability criterion. The individual and coupling effect of mass and stiffness distribution on the ... -
Effect of olive leaf (Olea europea L.) extracts on protein and lipid oxidation in cooked pork meat patties enriched with n-3 fatty acids
(2014)BACKGROUNDThe effect of olive leaf extracts on lipid and protein oxidation of cooked pork patties refrigerated stored for 9 days was evaluated. Patties were prepared from longissimus dorsi muscle of pigs, and dietary ... -
Effects of aflatoxin B1 administration on Greek indigenous goats' milk
(2012)Aflatoxins are toxic metabolites of the fungi Aspergillus spp. After aflatoxin B1 (AFB1) is consumed by lactating animals, it is metabolized to aflatoxin M1 (AFM1), which is excreted into the milk. The present study ... -
Electrochemical properties of ceramic membranes based on SrTi0.5Fe0.5O3-delta in reduced atmosphere
(2012)The present work aims at the investigation of the electrochemical properties of SrTi0.5Fe0.5O3-delta as a membrane material for hydrogen production via electrochemical reforming. The dependence of the electrical conductivity ... -
Excessive tibial rotation during high-demand activities is not restored by anterior cruciate ligament reconstruction
(2005)Purpose: Recent in vitro research has suggested that anterior cruciate ligament (ACL) reconstruction does not restore control of tibial rotation. The purpose of this study was to explore these findings in vivo and investigate ... -
Experimental evidence for a short-wave global mode in film flow along periodic corrugations
(2013)The primary instability of liquid film flow along periodically corrugated substrates is studied experimentally. Two different wall shapes, of the same wavelength and height, are tested for a wide range of inclinations. It ... -
Experimental study of inclined film flow along periodic corrugations: The effect of wall steepness
(2006)Gravity-driven film flow along an inclined periodic wall with transverse rectangular corrugations is studied experimentally. The effect of corrugation steepness (=height/length) is considered in detail and an interesting ... -
A fast iterative model for discrete velocity calculations on triangular grids
(2010)A fast synthetic type iterative model is proposed to speed up the slow convergence of discrete velocity algorithms for solving linear kinetic equations on triangular lattices. The efficiency of the scheme is verified both ... -
Finite element simulations of window Josephson junctions
(2012)This paper deals with the numerical simulation of the steady state two dimensional window Josephson junctions by finite element method. The model is represented by a sine-Gordon type composite PDE problem. Convergence and ... -
THE INFLUENCE OF MULTIPLE ADMINISTRATION OF A PSYCHOMOTOR TEST ON PERFORMANCE AND LEARNING
(2008)Tsigilis, N and Theodosiou, A. The influence of multiple administration of a psychomotor test on performance and learning. J Strength Cond Res 22(6): 1964-1968, 2008-Exercise scientists frequently use criterion measure ... -
Inhibition of human poly(A)-specific ribonuclease (PARN) by purine nucleotides: kinetic analysis
(2009)Poly(A)-specific ribonuclease (PARN) is a cap-interacting and poly(A)-specific 3'-exoribonuclease that efficiently degrades mRNA poly(A) tails. Based on the enzyme's preference for its natural substrates, we examined the ... -
Interactions of Oximino-Substituted Boronic Acids and beta-Lactams with the CMY-2-Derived Extended-Spectrum Cephalosporinases CMY-30 and CMY-42
(2013)CMY-30 and CMY-42 are extended-spectrum (ES) derivatives of CMY-2. ES characteristics are due to substitutions of Gly (CMY-30) and Ser (CMY-42) for Val211 in the Omega-loop. To characterize the effects of 211 substitutions, ... -
Kinetics of strain-induced transformation of dispersed austenite in low-alloy TRIP steels
(2014)A model describing the kinetics of the evolution of martensite volume fraction during the strain-induced transformation of dispersed austenite in low-alloy TRIP steels has been developed. The model is based on the modification ... -
Linear resonance in viscous films on inclined wavy planes
(2008)We study viscous gravity-driven films flowing over periodically undulated substrates. Linear analysis describes steady flow along small amplitude corrugations for films of arbitrary thickness. Solving the resulting system ... -
Load Path Effects in Circular Steel Columns under Bidirectional Lateral Cyclic Loading
(2015)Rigorous numerical analyses are conducted to study the effects of bidirectional lateral cyclic loading on the hysteretic response of stocky circular thin-walled steel columns. Four unidirectional and eight bidirectional ... -
Management zones delineation using fuzzy clustering techniques in grapevines
