Body fatness affects feed intake of sheep at a given body weight
(2006)In a 1-yr experiment, nutritional treatments were used to produce different combinations of BW and BCS in lambs. The experiment served to quantify the effects of BW and BCS on ADFI by sheep. Ewe lambs (n = 78) were assigned ... -
The Contribution of Stretch-Shortening Cycle and Arm-Swing to Vertical Jumping Performance in Children, Adolescents, and Adult Basketball Players
(2008)This study examined from childhood to adulthood: (1) the effects of countermovement (use of stretch-shortening cycle-SSC) and arm-swing (AS) on vertical jumping (W) performance and (2) the ability to use the SSC and AS ... -
Cultivation and characterization of Cynara Cardunculus for solid biofuels production in the Mediterranean region
(2008)Technical specifications of solid biofuels are continuously improved towards the development and promotion of their market. Efforts in the Greek market are limited, mainly due to the climate particularity of the region, ... -
Energy Distribution of a Regular Black Hole Solution in Einstein-Nonlinear Electrodynamics
(2015)A study about the energy momentum of a new four-dimensional spherically symmetric, static and charged, regular black hole solution developed in the context of general relativity coupled to nonlinear electrodynamics is ... -
Enhancing the efficacy of the 20 m multistage shuttle run test
(2005)Objective: Maximal oxygen uptake ( Vo(2max)) of 44 ml kg(-1) min(-1) is an accepted criterion (Vo(2CR)) below which health and fitness for young male adults may be compromised. New algorithms validated for Vo2CR screening ... -
Exergy Analysis of an Intermediate Temperature Solid Oxide Fuel Cell-Gas Turbine Hybrid System Fed with Ethanol
(2012)In the present work, an ethanol fed Solid Oxide Fuel Cell-Gas Turbine ( SOFC-GT) system has been parametrically analyzed in terms of exergy and compared with a single SOFC system. The solid oxide fuel cell was fed with ... -
Impact of beam quality on megavoltage radiotherapy treatment techniques utilizing gold nanoparticles for dose enhancement
(2013)This study determines the optimal clinical scenarios for gold nanoparticle dose enhancement as a function of irradiation conditions and potential biological targets using megavoltage x-ray beams. Four hundred and eighty ... -
Inflorescence characteristics, seed composition, and allometric relationships predicting seed yields in the biomass crop Cynara cardunculus
(2010)Cynara (Cynara cardunculus) is a perennial C(3) herb that has its potential as bioenergy crop. This paper aims (a) to derive empirical relationships to predict cynara seed yield per head and per unit area, avoiding laborious ... -
INFRARED HEATING OF GREENHOUSES REVISITED: AN EXPERIMENTAL AND MODELING STUDY
(2009)The potential advantages of night-time heating of greenhouses by modern infrared (IR) radiative sources, instead of forced hot air, are examined experimentally and theoretically. Measurements of indoor and outdoor conditions ... -
Interrill erosion on cultivated Greek soils: modelling sediment delivery
(2006)For interrill erosion, raindrop-induced detachment and transport of sediment by rainfall-disturbed sheet flow are the predominant processes, while detachment by sheet flow and transport by raindrop impact are negligible. ... -
A parametric study of a solar calcinator using computational fluid dynamics
(2007)In this work a horizontal rotating solar calcinator is studied numerically using computational fluid dynamics. The specific solar reactor is a 10 kW model designed and used for efficiency studies. The numerical model is ... -
Recovery Mechanisms in Day-Ahead Electricity Markets With Non-Convexities-Part I: Design and Evaluation Methodology
(2013)In centralized day-ahead electricity markets with marginal pricing, unit commitment costs and capacity constraints give rise to non-convexities which may result in losses to some of the participating generating units. ... -
Scheduling with pairwise XORing of packets under statistical overhearing information and feedback
(2012)We study the problem of scheduling packets from several flows traversing a given node which can mix packets belonging to different flows. Practical wireless network coding solutions depend on knowledge of overhearing events ... -
Size effects on strength, toughness and fatigue crack growth of gradient elastic solids
(2008)The present study investigates the microstructural size effect on the strength of a bar under axial loading, and on the toughness and crack growth of a beam under three-point bending within the framework of strain gradient ... -
Static response and stability of coated microbubbles-multiplicity of solutions and parameter estimation
(2014)The static response of a coated microbubble subject to an external pressure distribution is investigated, in order to identify different response patterns with varying viscoelastic properties of the shell. Theoretical and ... -
Supplementation of lactating ewes with a glucogenic preparation or beta-carotene in mid- to late lactation on subsequent milk yield and luteinizing hormone secretion
(2007)The effects of a glucogenic preparation (Nutrimix((R))) or beta-carotene (Rovimix((R)) beta carotene) supplementation of ewes during mid- to late-lactation on their milk yield were assessed in a study where 66 Chios-breed ...
