Cu-Zn powders as potential Cr(VI) adsorbents for drinking water
(2013)This work examines the possibility of applying CuZn alloys as a reducing medium for the efficient removal of hexavalent chromium from drinking water. In an effort to develop a route for producing powders of CuZn alloys ... -
Decolorization kinetics of Procion H-exl dyes from textile dyeing using Fenton-like reactions
(2006)The decolorization kinetics of three commercially used Procion H-exl dyes was studied using a Fenton-like reagent. The effect of the major system parameters (pH, concentration of H2O2 and Fe3+ and initial dye concentration) ... -
Defining threshold values for pavement surface characteristics
(2015)In the context of a rational road management strategy, pavement surface characteristics, which significantly affect comfort and safety, have to be adequately monitored and appraised in the frame of routine or preventive ... -
Degradation products of the process of thermal recovery of copper from lamina scraps in lab-scale fluidized bed reactor
(2004)This paper presents experimental results dealing with a process for recovering copper in the scrap composite materials issued from electronic laminas industry. This environment-friendly process consists in the thermal ... -
Design in shear of reinforced concrete short columns
(2013)This research was prompted by the paucity of specific code provisions regarding the design of short columns for shear. The purpose of this paper was to investigate whether the use of the normal shear design procedure of ... -
Design of Reinforced Concrete Infilled Frames
(2014)The work presented in this paper aimed to evaluate the diagonal strut model for the design of reinforced concrete (RC) infilled frames, already broadly used as a design tool in the case of masonry infilled RC frames. The ... -
Direct estimation of seismic demand and capacity of multidegree-of-freedom systems through incremental dynamic analysis of single degree of freedom approximation
(2005)Introducing a fast and accurate method to estimate the seismic demand and capacity of first-mode-dominated multidegree-of-freedom systems in regions ranging from near-elastic to global collapse. This is made possible by ... -
Do Road Safety Communication Campaigns Work? How to Assess the Impact of a National Fatigue Campaign on Driving Behavior
(2013)Road safety communication campaigns are considered an efficient strategy for reaching a wide audience. They aim at reducing the number and severity of road crashes by influencing road user behavior. Despite the large number ... -
The DPSIR Approach for an Integrated River Management Framework. A Preliminary Application on a Mediterranean Site (Kalamas River -NW Greece)
(2012)The European Water Policy introduced the necessity to apply new methodological approaches for the sustainable management of water resources. In the present paper the Driving-Pressure-State-Impact-Response (DPSIR) framework ... -
The effect of joint flexibility on the free elastic vibration characteristics of steel plane frames
(2003)The present work offers a simplified approach for establishing the effect of joint flexibility on the free vibration characteristics of steel plane frames. Based on the beam-to-column model of Eurocode 3, the presented ... -
Effects of B20 on the Operation of a Single-Cylinder Engine Equipped with a SiC Diesel Particulate Filter
(2014)This is an experimental and computational study of the effect of a low-percentage biodiesel blend on the operation, diesel filter loading, and fuel additive-assisted regeneration behavior on a conventional, direct injection ... -
The effects of construction practices on the seismic performance of RC frames with masonry infills
(2008)A number of construction practices, implemented during the design process of a reinforced concrete (RC) structural system, may have significant consequences on the behaviour of the structural system in the case of earthquake ... -
Efficiency of Eurocode 8 design rules for steel and steel-concrete composite structures
(2015)Seismic design codes allow the realization of structures able to dissipate energy through cyclic plastic deformations located in specific regions, selected to involve the largest number of structural elements. The capacity ... -
Evaluation of actions on concrete sleepers as design loads - influence of fastenings
(2010)In Greece, during the 1980s, 60% of the twin-block concrete sleepers designed for lines of mixed traffic and a maximum speed of 200km/h, which were laid on a track with a maximum operational speed of 140km/h, presented ... -
Evaluation study of a Navier-Stokes CFD aeroelastic model of wind turbine airfoils in classical flutter
(2008)This paper describes a new aeroelastic numerical model, which combines a Navier-Stokes CFD solver with an elastic model and two coupling schemes for the study of the aeroelastic behaviour of wind turbine blades undergoing ... -
