Carotid Bifurcation Geometry as Assessed by Ultrasound is Associated with Early Carotid Atherosclerosis
(2018)Background: Atherosclerosis usually develops at geometrically susceptible areas, despite the impact of systemic risk factors on the entire vascular system. The aim of our study was to investigate whether carotid bifurcation ... -
Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows
(2022)Homochirality is a fundamental feature of living systems, and its origin is still an unsolved mystery. Previous investigations showed that external physical forces can bias a spontaneous symmetry breaking process towards ... -
The effect of anode bed geometry on the hydraulic behaviour of PEM fuel cells
(2016)The influence of the anode bed geometry on the hydraulic behaviour of PEM fuel cells is assessed. Three basic geometrical patterns are studied, namely the interdigitated, the parallel and the serpentine ones, in their ... -
Effect of micropolar fluid properties on the hydraulic permeability of fibrous biomaterials
(2020)Background and objective: In this work, the effect of the micropolar fluid parameters on the hydraulic permeability of fibrous biomaterials comprised of square arrays of undirectional fibrils is investigated. Methods: ... -
Failure Analysis of Two Ti-Alloy Total Hip Arthroplasty Femoral Stems Fractured In Vivo
(2003)Failure of total hip arthroplasty femoral stems is a serious clinical complication. Even modern metal alloys and designs sometimes suffer such incidents. The reported study aimed at the investigation of the reasons leading ... -
Fatigue of textiles used in vascular surgery: Application to carotid endarterectomy
(2021)Fatigue is a material-based phenomenon playing a significant role in the mechanical behavior of components and structures. Although fatigue has been well studied for traditional materials, such as metals, its underlying ... -
A field trial of a fixed combination of permethrin and fipronil (Effitix®) for the treatment and prevention of flea infestation in dogs living with sheep
(2017)Background: A large number of fleas parasitize dogs living with sheep in Greece. The primary aim of this randomized, blinded, placebo-controlled trial was to examine the efficacy of a permethrin-fipronil combination ... -
Investigation of speed and trajectory of motorcycle riders at curved road sections of two-lane rural roads under diverse lighting conditions
(2021)Introduction: Vehicular accidents at horizontal curves are over-represented compared to accidents that occur at tangent sections. Investigations have been conducted aimed at identifying the major causes that result in ... -
Longitudinal Adaptations of Bone Mass, Geometry, and Metabolism in Adolescent Male Athletes: The PRO-BONE Study
(2017)Adolescence is a crucial period for bone development, and exercise can enhance bone acquisition during this period of life. However, it is not known how the different loading sports practiced can affect bone acquisition ... -
Longitudinal determinants of 12-month changes on bone health in adolescent male athletes
(2018)Summary: We identified the determinants of 12-month changes of areal bone mineral density (aBMD), hip geometry and trabecular bone score (TBS) in adolescent male athletes. Changes in region-specific lean mass and the type ... -
Morphological and free amino acid profile variability, as a tool for stock identification among farmed rainbow trout Oncorhynchus mykiss of different origin
(2018)As a tool for stock identification the body morphology and the free amino acid (FAA) profile variability were determined among farmed rainbow trout Oncorhynchus mykiss (Walbaum 1792) from different geographical areas ... -
Numerical study of mechanically ventilated broiler house equipped with evaporative pads
(2018)One of the important factors to improve the broiler production is the provision of an optimum indoor environment (air quality, temperature, humidity, air velocity, gases and PMs concentration) with lower possible cost. The ... -
Optimizing the formation of DMAs in a water distribution network through advanced modelling
(2019)Water pressure management in a water distribution network (WDN) is a key component applied to achieve desirable water quality as well as a trouble-free operation of the network. This paper presents a hybrid, two-stage ...
