Effects of different N fertilizers on the activity of Glomus mosseae and on grapevine nutrition and berry composition
(2007)Grapevine N fertilization may affect and be affected by arbuscular mycorrhizal (AM) fungal colonization and change berry composition. We studied the effects of different N fertilizers on AM fungal grapevine root colonization ... -
Effects of Pea Cultivation as Cover Crop on Nitrogen-Use Efficiency and Nitrogen Uptake by Subsequent Maize and Sunflower Crops in a Sandy Soil in Central Greece
(2013)The long-term positive effects of cropping systems involving rotation with cover crops on soil properties and the environment are well recognized. The present work concerns a 3-year field experiment focusing on two cropping ... -
Effects of soil application of olive mill wastewaters on the structure and function of the community of arbuscular mycorrhizal fungi
(2009)Recycling of olive mill wastewaters (OMW) into agricultural soils is a controversial issue since benefits to soil fertility should counterbalance potential short-term toxicity effects. We investigated the short-term effects ... -
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 ... -
Evaluation of powder/granular Gd2O2S:Pr scintillator screens in single photon counting mode under 140 keV excitation
(2013)The aim of this paper is the evaluation of an alternative, low cost solution for the gamma detector in planar imaging. It is based on a powder scintillator, well established in X-ray imaging, and could be further exploited ... -
Inplane deformation of a circular inhomogeneity with imperfect interface
(1998)The plane elastic problem of a circular inhomogeneity with an imperfect interface of spring-constant-type is reduced to the solution of a Somigliana dislocation problem, when the solution for the corresponding problem with ... -
Laminar Free Convection in a Square Enclosure Driven by the Lorentz Force
(2010)A numerical study is presented of laminar free convection flow driven by magnetic forces. An external magnetic field with one spatially varying component is applied to an electrically conducting fluid in a square enclosure. ... -
On the limits of validity of the low magnetic Reynolds number approximation in MHD natural-convection heat transfer
(2006)In the majority of magnetohydrodynamic (MHD) natural-convection simulations, the Lorentz force due to the magnetic field is suppressed into a damping term resisting the fluid motion. The primary benefit of this hypothesis, ... -
The politics and science behind GMO acceptance
(2007)The question of nutritional quality has arisen in the International Community over the last few years along with other important issues such as population aging, multipopulation societies, and political conflicts. The ... -
Soil spatial variability and site-specific fertilization maps in an apple orchard
(2011)In the present study, the spatial variability of some soil physical and chemical properties in a 0.8 ha apple orchard were studied. Sixty soil samples were taken from two sampling depths: 0-0.3 m and 0.3-0.6 m. The soil ... -
Spatio-temporal population dynamics and area-wide delineation of Bactrocera oleae monitoring zones using multi-variate geostatistics
(2012)Area-wide integrated pest management requires an understanding of insect population dynamics and definition of suitable techniques to quantify spatio-temporal variability to make better pest management decisions. However, ... -
Vertical jumping ability in elite young soccer players
(2006)The jumping ability of a soccer player, as an expression of power, is a basic factor for good performance in the specific sport. The purpose of the present study was to measure and evaluate the power of the leg extensors ...
