Condition-Dependent Effects of Mating on Longevity and Fecundity of Female Medflies: The Interplay between Nutrition and Age of Mating
(2013)Background: In various species mating exerts direct and indirect effects on female demographic traits ranging from life span shortening to behavioural shifts. A wealth of data regarding effects of nutrition on longevity ... -
A conditional nonparametric analysis for measuring the efficiency of regional public healthcare delivery: An application to Greek prefectures
(2011)Objectives: The purpose of this study is to measure the Greek public healthcare delivery efficiency from a regional perspective by applying conditional nonparametric models. Methods: The study reviews the existing literature ... -
Connectivity Issues for Ultraviolet UV-C Networks
(2011)This paper focuses on the connectivity issues of a non-line-of-sight (NLOS) optical wireless network operating in the ultraviolet UV-C spectral region. NLOS UV-C transmitters have a limited effective coverage and, hence, ... -
Creating a Brief Rating Scale for the Assessment of Learning Disabilities Using Reliability and True Score Estimates of the Scale's Items Based on the Rasch Model
(2013)The purpose of the present studies was to provide the means to create brief versions of instruments that can aid the diagnosis and classification of students with learning disabilities and comorbid disorders (e.g., ... -
Cross-layer adaptive techniques for throughput enhancement in wireless OFDM-based networks
(2006)Although independent consideration of layers simplifies wireless system design, it is inadequate since: 1) it does not consider the effect of co-channel user interference on higher layers; 2) it does not address the impact ... -
Determinants of hazard confronting new entry: Does financial structure matter?
(2000)This paper attempts to identify the determinants of hazard confronting 219 new manufacturing firms established in 1982-84 and followed up to 1992 using a Cox regression model. Three sets of variables are combined in the ... -
Diffusion tensor imaging (DTI) in the detection of white matter lesions in patients with mild cognitive impairment (MCI)
(2013)Mild cognitive impairment (MCI) is recognized as a precursor to dementia. The amnestic MCI progresses usually to Alzheimer disease. Amnestic MCI multiple domain (md-MCI) seems to progress more rapidly than amnestic MCI ... -
Direct ethanol fuel cells: The effect of the cell discharge current on the products distribution
(2010)In the present work the results of the continuous and on-line product analysis during a Direct Ethanol Polymer Electrolyte Membrane Fuel Cell operation (DE-PEMFC) are presented. The effect of both cell discharge current ... -
Direct ethanol PEM fuel cells: The case of platinum based anodes
(2005)PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ... -
Do Patients with Alzheimer's Disease Draw like Young Children? An Exploratory Study
(2015)Background: Previous studies have shown that AD patients present a stepwise regression to their cognitive functioning from a mature adult to that of an infant. Objectives: The present study aimed to compare Alzheimer's ... -
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 ... -
Dose-related effects of prolonged NaHCO3 ingestion during high-intensity exercise
(2006)Purpose: Sodium bicarbonate (NaHCO3) ingestion may prevent exercise-induced perturbations in acid-base balance, thus resulting in performance enhancement. This study aimed to determine whether different levels of NaHCO3 ... -
Duality theory and cost function analysis in a regional context: the impact of public infrastructure capital in the Greek regions
(2002)The resurgent interest in the role of infrastructure on development, spurred by the work on Aschauer in the late eighties, has produced a voluminous research activity, both at national and regional levels. Even though the ... -
Effect of a special carbohydrate-protein bar and tomato juice supplementation on oxidative stress markers and vascular endothelial dynamics in ultra-marathon runners
(2014)It is well established that exercise induces excessive production of reactive species leading to oxidative stress, which has been implicated in oxidative damage of macromolecules, immune dysfunction, muscle damage and ... -
THE EFFECT OF ACCESS TO IMPROVED WATER SOURCES AND SANITATION ON ECONOMIC EFFICIENCY: THE CASE OF SUB-SAHARAN AFRICAN COUNTRIES
(2012)This paper evaluates the effect of access to improved water sources and sanitation on 41 sub-Saharan African (SSA) countries' economic efficiency and growth. For this reason data envelopment analysis (DEA), bootstrap ... -
Effect of Bacillus licheniformis and Bacillus subtilis supplementation of ewe's feed on sheep milk production and young lamb mortality
(2006)The purpose of this pilot study was to evaluate under field conditions the effect of a probiotic containing Bacillus licheniformis and Bacillus subtilis on young lamb mortality and sheep milk production when administered ... -
Effect of benzoic acid and combination of benzoic acid with a probiotic containing Bacillus Cereus var. toyoi in weaned pig nutrition
(2011)The purpose of this study was to assess the efficacy of a probiotic containing Bacillus cereus var. Toyoi spores (Toyocerin (R)) and benzoic acid (VevoVitall (R)) on growth performance and diarrhoea in weaning pigs, against ... -
The effect of different goals and self-recording on self-regulation of learning a motor skill in a physical education setting
(2011)This study examined the effect of different goals (process, performance outcome, and multiple goals) and self-recording on self-regulation of learning a dart-throwing skill. Participants were 105 fifth and sixth graders ... -
