- ItemA genre-based framework for constructing multimodal content for learning objects
Τμήμα Επιστημών της Εκπαίδευσης και της Αγωγής στην Προσχολική Ηλικία (Δημοσ. Π.Π. σε περιοδικά)Vorvilas, George; Karalis, Thanassis; Ravanis, Konstantinos; Βορβυλάς, Γεώργιος; Καραλής, Θανάσης; Ραβάνης, ΚωνσταντίνοςIn the present article we propose a genre-based conceptual framework for designing content for learning objects. We review some content aggregation models in order to stress the lack of such an approach. We also consider learning objects as multimodal macrogenres. These macrogenres are constituted of content object assemblies. The successful and coherent aggregation of these content objects can be achieved through the recognition of potential rhetorical relations among them. Finally, adopting this framework, an author/teacher is supported with a repertoire of concepts that make him capable of affect and motivate students in particular ways through her intended learning materials.
- ItemAir flow characteristics in an industrial wood pallet drying kiln
Τμήμα Μηχανολόγων και Αεροναυπηγών Μηχαν. (Δημοσ. Π.Π. σε συνέδρια)(2010-07-21T09:52:17Z) Tzempelikos, Dimitrios; Filios, Andronikos; Margaris, Dionisios; Τζεμπελίκος, Δημήτριος; Φίλιος, Ανδρόνικος; Μάργαρης, ΔιονύσιοςThe improvement and optimization of air-distribution systems in drying kilns contributes to the preservation of the quality, safety and shelf life of perishable products. The present study reports on the numerical solution of airflow within a two dimensional drying kiln enclosure loaded with wooden pallets. The performance of air flow field is examined with and without supply of wooden pallets. Different arrangements of the supplied wooden pallets are investigated as well as the use of a screen in order to improve the airflow filed. The steady state RANS equations that formulate the flow problem are solved along with a turbulence model that is the standard k-εor the rng k-ε. The effect of the turbulence modeling is distinguished through direct comparisons of the derived airflow patterns. The results obtained show the presence of stagnant zones inside the pallets columns and above of them and the presence of recirculation regions in different zones of the drying kiln with the two turbulence models.

- ItemAirflow patterns in a laboratory batch-type, tray air dryer
Τμήμα Μηχανολόγων και Αεροναυπηγών Μηχαν. (Δημοσ. Π.Π. σε συνέδρια)(2013-07-30) Tzempelikos, Dimitrios; Vouros, Alexandros; Bardakas, Achilleas; Filios, Andronikos; Margaris, Dionissios; Τζεμπελίκος, Δημήτριος; Βούρος, Αλέξανδρος; Μπαρδάκας, Αχιλλέας; Φιλιός, Ανδρόνικος; Μάργαρης, ΔιονύσιοςThe batch-type dryer is one of the most popular equipment for fruit drying. However, the optimization of the air distribution inside the drying chamber remains a very important issue, due to its strong impact on efficient drying and uniformity of moisture content of products. A new scale laboratory batch-type, tray air dryer has been designed, constructed and evaluated for drying several horticultural and agricultural products. The flow field inside the dryer is studied through computational fluid dynamics (CFD). A three-dimensional model for laboratory dryer has been created and the steady state incompressible, Reynolds-Averaged Navier-Stokes (RANS) equations that formulate the flow problem are solved, incorporating standard and RNG k-ε turbulence models. The simulations are conducted for testing chamber average velocity of 2,9 m/s at ambient temperature. The CFD models are evaluated by comparing airflow patterns and velocity distributions to measured data. Numerical simulations and measurements convince that the new scale laboratory batch-type dryer is able to produce a sufficiently uniform air distribution throughout the testing chamber of the dryer.
- ItemAirway trauma : a review on epidemiology, mechanisms of injury, diagnosis and treatment
Τμήμα Ιατρικής (Δημοσ. Π.Π. σε περιοδικά)Prokakis, Christos; Dedeilias, Panagiotis; Filos, Kriton; Koletsis, Efstratios; Fligou, Foteini; Dougenis, Dimitrios; Προκάκης, Χρήστος; Δεδεήλιας, Παναγιώτης; Φίλος, Κρίτων; Κολέτσης, Ευστράτιος; Φλίγκου, Φωτεινή; Δουγενής, ΔημήτρηςAirway injuries are life threatening conditions. A very little number of patients suffering air injuries are transferred live at the hospital. The diagnosis requires a high index of suspicion based on the presence of non-specific for these injuries symptoms and signs and a thorough knowledge of the mechanisms of injury. Bronchoscopy and chest computed tomography with MPR and 3D reconstruction of the airway represent the procedures of choice for the definitive diagnosis. Endotracheal intubation under bronchoscopic guidance is the key point to gain airway control and appropriate ventilation. Primary repair with direct suture or resection and an end to end anastomosis is the treatment of choice for patients suffering from tracheobronchial injuries (TBI). The surgical approach to the injured airway depends on its location. Selected patients, mainly with iatrogenic injuries, can be treated conservatively as long as the injury is small (<2 cm), a secure and patent airway and adequate ventilation are achieved, and there are no signs of sepsis. Patients with delayed presentation airway injuries should be referred for surgical treatment. Intraoperative evaluation of the viability of the lung parenchyma beyond the site of stenosis/obstruction is mandatory to avoid unnecessary lung resection.
- ItemAllergic inflammation does not impact chemical-induced carcinogenesis in the lungs of mice
Τμήμα Ιατρικής (Δημοσ. Π.Π. σε περιοδικά)(2011-12-02) Doris, Konstantinos; Karabela, Sophia P; Kairi, Chrysoula; Simoes, Davina CM; Roussos, Charis; Zakynthinos, Spyros G; Kalomenidis, Ioannis; Blackwell, Timothy S; Stathopoulos, Georgios T; Doris, Κωνσταντίνος; Καράμπελα, Σοφία Π; Καΐρη, Χρυσούλα; Simoes, Davina CM; Ρούσσος, Χάρης; Ζακυνθινός, Σπύρος Γ; Καλομενίδης, Ιωάννης; Blackwell, Timothy S; Σταθόπουλος, Γεώργιος ΤAlthough the relationship between allergic inflammation and lung carcinogenesis is not clearly defined, several reports suggest an increased incidence of lung cancer in patients with asthma. We aimed at determining the functional impact of allergic inflammation on chemical carcinogenesis in the lungs of mice. Methods Balb/c mice received single-dose urethane (1 g/kg at day 0) and two-stage ovalbumin during tumor initiation (sensitization: days -14 and 0; challenge: daily at days 6-12), tumor progression (sensitization: days 70 and 84; challenge: daily at days 90-96), or chronically (sensitization: days -14 and 0; challenge: daily at days 6-12 and thrice weekly thereafter). In addition, interleukin (IL)-5 deficient and wild-type C57BL/6 mice received ten weekly urethane injections. All mice were sacrificed after four months. Primary end-points were number, size, and histology of lung tumors. Secondary end-points were inflammatory cells and mediators in the airspace compartment. Results Ovalbumin provoked acute allergic inflammation and chronic remodeling of murine airways, evident by airspace eosinophilia, IL-5 up-regulation, and airspace enlargement. Urethane resulted in formation of atypical alveolar hyperplasias, adenomas, and adenocarcinomas in mouse lungs. Ovalbumin-induced allergic inflammation during tumor initiation, progression, or continuously did not impact the number, size, or histologic distribution of urethane-induced pulmonary neoplastic lesions. In addition, genetic deficiency in IL-5 had no effect on urethane-induced lung tumorigenesis. Conclusions Allergic inflammation does not impact chemical-induced carcinogenesis of the airways. These findings suggest that not all types of airway inflammation influence lung carcinogenesis and cast doubt on the idea of a mechanistic link between asthma and lung cancer.
- ItemAn Aegean History and Archaeology Written through Radiocarbon Dates
Τμήμα Ιστορίας - Αρχαιολογίας (Δημοσ. Π.Π. σε περιοδικά)(Ubiquity Press, ) Katsianis, Markos; Bevan, Andrew; Styliaras, Giorgos; Maniatis, Yannis; Κατσιάνης, Μάρκος; Στυλιάρας, Γεώργιος; Μανιάτης, ΓιάννηςThis dataset is the outcome of an INSTAP-funded project “An Aegean Prehistory Written in Radiocarbon Dates”. It includes 3159 14C dates from 353 sites in Greece and reflects an attempt to exhaustively collect and cross-check all published radiocarbon dates from existing databases, original publications and preliminary reports using both international and Greek sources (376 sources in total). Although originally targeting prehistoric dates, all dates coming from archaeological or environmental sampling were integrated in the final dataset regardless of chronological period. Sites have been identified and positioned as accurately as possible, while additional information on sampling procedures, sample material and stratigraphic context have been recorded.
- ItemAn experimental study on convective drying of quince
Τμήμα Μηχανολόγων και Αεροναυπηγών Μηχαν. (Δημοσ. Π.Π. σε συνέδρια)(2013-08-06) Tzempelikos, Dimitrios; Bardakas, Achilleas; Vouros, Alexandros; Tsepenekas, Dionysios; Filios, Andronikos; Margaris, Dionissios; Τζεμπελίκος, Δημήτριος; Μπαρδάκας, Αχιλλέας; Βούρος, Αλέξανδρος; Τσεπενέκας, Διονύσιος; Φιλιός, Ανδρόνικος; Μάργαρης, ΔιονύσιοςA laboratory convective drying unit (LCDU) has been designed, constructed and equipped with an integrated measurement and control instrumentation, in order to evaluate the essential drying characteristics of various horticultural and agricultural products. The current paper presents experimental results from tests with quince slices. Drying kinetics was investigated as a function of drying conditions. Experiments were conducted at air flow temperatures of 40, 50 and 60oC and average velocities of 1, 2 and 3 m/s. Temperature changes of the drying quince samples, the relative humidity and the temperature of the drying air were measured during the drying processes and finally the moisture ratio (MR) was calculated. The experimental MR data were fitted with three mathematical models available in the literature and a good agreement was observed. In the ranges measured, Fick’s 2nd law of diffusion was used to fit the experimental data for the determination of the effective moisture diffusivity. The activation energy was determined, assuming an Arrhenius type temperature relationship with moisture diffusivity.
- ItemAn in vitro study, evaluating the effect of sunitinib and/or lapatinib on two glioma cell lines
Τμήμα Ιατρικής (Δημοσ. Π.Π. σε περιοδικά)(2013-12-03) Giannopoulou, Efstathia; Dimitropoulos, Konstantinos; Argyriou, Andreas; Koutras, Angelos; Dimitrakopoulos, Fotinos; Kalofonos, Haralabos; Γιαννοπούλου, Ευσταθία; Δημητρόπουλος, Κωνσταντίνος; Αργυρίου, Ανδρέας; Κούτρας, Άγγελος; Δημητρακόπουλος, Φωτεινός; Καλόφωνος, ΧαράλαμποςAim: We sought to assess the effect of sunitinib and lapatinib applied either alone or in combination, on U87 and M059K glioma cells. Methods: Both cell lines were cultured as recommended by the manufacturer. Sunitinib and lapatinib were applied, either separately or in combination, in the cultured cells after cell attachment at doses of 10nM, 100nM, 1μM and 10 μM. To determine whether the agents affect the proliferation of glioma cells, the 3-[4,5-dimethylthiazol-2-yl]-2,5 dimethyltetrazolium bromide assay was used. Apoptosis was detected using annexin V/propidium iodide detection assay, migration assay was performed in 24-well microchemotaxis chambers. The release of MMPs into the culture medium of U87 and M059K cells was measured by zymography. Results: Both agents, administered either alone or in combination, decreased cell proliferation in a dose-dependent manner 48 h after their application in both cell lines. The inhibition of their combination was statistically different than the inhibition of each agent alone. Apoptosis was increased and migration of U87 and M059K cells was inhibited either by each agent alone or their combination. MMPs levels remained unaffected by the application of both agents in U87 cells. However, MMP-9 and MMP-2 levels were decreased 48h after treatment of M059K cells with sunitinib either alone or in combination with lapatinib. Conclusion: Sunitinib and/or lapatinib appear to exhibit significant effects on proliferation, apoptosis and migration of glioma cells. When applied alone, sunitinib appears to be a more potent inhibitor than lapatinib.

The 24 primary outcome was the percent difference of uncovered struts between BESs and PESs. 25 Results: A maximum likelihood model was used for analysis, to account for data clustering. Sixteen patients 26 were treated with BES (28 lesions/4530 struts) and 16 with PES (23 lesions/4450 struts). Overall, BESs 27 compared to PESs had more uncovered [0.41% vs. 0.21%, difference estimate (DE) 0.2 (95% CI, 0.06–0.34), 28 p=0.006], malapposed [0.18% vs. 0.04%, DE 0.14 (95% CI 0.05–0.23), p=0.003], uncovered and malapposed 29 [0.08% vs. 0.026%, DE 0.057 (95% CI 0.015–0.1), p=0.01] and protruding struts [0.23% vs. 0.04%, DE 0.185 (95% 30 CI 0.1–0.27), pb0.001], and significantly lower neointimal thickness (59.3± 28.2 μm vs. 201.7± 97.5, 31 pb0.001). None of the BESs was totally covered with neointima, in contrast to 5 (21.7%) PESs (p=0.01). 32 Thrombus was detected in 1 (3.6%) BES and 5 (21.7%) PESs (p=0.05); however, no patient experienced 33 clinical stent thrombosis. 34 Conclusion: Between two stents with biodegradable polymer, OCT demonstrated that BESs had more 35 uncovered and malapposed struts compared to PESs at 6 months. This difference might be partly attributed to 36 the more potent antiproliferative properties of biolimus-A9; however, its impact on clinical outcome and on 37 the risk of LST is yet to be determined.
- ItemAnalysis of air velocity distribution in a laboratory batch-type tray air dryer by computational fluid dynamics
Τμήμα Μηχανολόγων και Αεροναυπηγών Μηχαν. (Δημοσ. Π.Π. σε περιοδικά)(2013-03-12) Tzempelikos, Dimitrios; Vouros, Alexandros; Bardakas, Achilleas; Filios, Andronikos; Margaris, Dionissios; Τζεμπελίκος, Δημήτριος; Βούρος, Αλέξανδρος; Μπαρδάκας, Αχιλλέας; Φιλιός, Ανδρόνικος; Μάργαρης, ΔιονύσιοςBatch dryers are some of the most widespread equipment used for fruit dehydration. Nevertheless, the optimization of the air distribution inside the drying chamber of a batch dryer remains a very important point, due to its strong effect on drying efficiency as well as the uniformity of the moisture content of the drying products. A new scale laboratory batch-type tray air (BTA) dryer was designed, constructed and evaluated for the drying of several horticultural and agricultural products. The airflow field inside the dryer was studied through a commercial computational fluid dynamics (CFD) package. A three-dimensional model for a laboratory BTA dryer was created and the steady-state incompressible, Reynolds-Averaged Navier-Stokes equations that formulate the flow problem were solved, incorporating standard and RNG k-ε turbulence models. In the simulation, the tray, used inside the BTA drying chamber, was modeled as a thin porous media of finite thickness. The simulations for testing the chamber were conducted at an average velocity of 2.9 m/s at ambient temperature. The CFD models were evaluated by comparing the airflow patterns and velocity distributions to the measured data. Numerical simulations and measurements showed that the new scale laboratory BTA dryer is able to produce a sufficiently uniform air distribution throughout the testing chamber of the dryer.
- ItemAnalysis of bone composition with Raman spectroscopy
Τμήμα Φαρμακευτικής (Δημοσ. Π.Π. σε συνέδρια)(2012-05-04) Kontoyannis, Christos; Orkoula, Malvina; Kalonakis, Konstantinos; Κοντογιάννης, Χρήστος; Όρκουλα, Μαλβίνα; Καλονάκης, ΚωνσταντίνοςBone is a composite material formed by the nucleation and growth of a mineral highly resembling calcium hydroxyapatite, Ca10(PO4)6(OH)2, within an organic matrix consisting mainly of type I collagen. Seventy percent of mature bone consists of the inorganic phase while the organic matrix and water fills the rest. Development of fast and reliable methodologies capable of analyzing chemically the major bone constituents is needed. In the present work, Raman spectroscopy, a non-destructive technique, was applied as such a tool on bovine cortical and trabecular parts of bone. Preliminary results show that their mineral to organic ratio differs at 30%.

- ItemAssessing the compression after impact behaviour of innovative multifunctional composites
Τμήμα Μηχανολόγων και Αεροναυπηγών Μηχαν. (Δημοσ. Π.Π. σε περιοδικά)Παντελάκης, Σπύρος; Κατσιρόπουλος, Χρήστος; Πολυδωροπούλου, Παναγιώτα; Pantelakis, Spyros; Katsiropoulos, Christos; Polydoropoulou, PanagiotaIn the present work, the synergistic effect of multiwalled carbon nanotubes and glycidyl polyhedral oligomeric silsesquioxanes on the compression after impact behaviour of multifunctional carbon fibre–reinforced epoxy composite plates is investigated. For the qualitative evaluation of the damage accumulation after impact, non-destructive ultrasonic C-scan tests were performed. The impact-induced material degradation was correlated with data obtained from C-scan graphs through applying the concept of the damage severity factor. The test results obtained from C-scan analysis have shown a significant increase of the damaged area after the impact tests, as compared to the unfilled material considered as ‘reference’. A reduced compression after impact strength is observed for the enhanced material as compared to the reference material. To identify the type of damage, optical microscope, scanning electron microscope and energy dispersive spectroscopy analyses were made after the tests. The optical microscope analysis has shown more extended cracking and delaminations for the enhanced material. Scanning electron microscopic analysis has revealed the presence of carbon nanotube agglomerates and possible glycidyl polyhedral oligomeric silsesquioxanes aggregates which might be the cause for a degraded compression after impact behaviour of the multifunctional composites.

Compared to cardiac surgery, carotid endarterectomy patients were older (71.05 ± 8.69 vs. 65.72 ± 11.04, P < 0.001), with higher baseline INVOS (P < 0.007) and greater stroke frequency (P < 0.002). Diabetes and high cholesterol were more common in cardiac surgery patients. Right side INVOS values were strongly correlated with left-side values in carotid (r = 0.772, P < 0.0001) and cardiac surgery patients (r = 0.697, P < 0.0001). Diabetes and high cholesterol were associated with significantly (P < 0.001) lower INVOS and smoking was associated with higher INVOS values in carotid, but not in cardiac surgery patients. Age, sex, CVA history, Hypertension, CAD, Asthma, carotid stenosis side and surgery side were not related to INVOS. Multivariate analysis showed that diabetes is strongly associated with lower baseline INVOS values bilaterally (P < 0.001) and explained 36.4% of observed baseline INVOS variability in carotid (but not cardiac) surgery.
- ItemBody expression skills training in a communication course for dental students
Τμήμα Επιστημών της Εκπαίδευσης και της Αγωγής στην Προσχολική Ηλικία (Δημοσ. Π.Π. σε περιοδικά)(2014-06-16) Ρήγα, Βασιλική; Κοσιώνη, Αναστασία; Riga, Vassiliki; Kossioni, AnastassiaBackground: In the health professions, competency in communication skills is necessary for the development of a satisfactory physician–patient interaction. Body expression is an important domain of τhe communication process, often not adequately addressed. The aim of this study was to describe the methodology and content of a pilot introductory training session in body expression for dental students before the beginning of their clinical training. Methods: The educational methods were based on experiential learning and embodied training, where the session’s content focused on five themes representing different phases of the dental treatment session. A questionnaire was distributed before and after the session to assess any changes in students’ self-perceptions in communication skills. Results: There were statistically significant improvements in the total values of the students self-perceptions of their communication skills obtained before and after the training and in specific elements such as small group situations, performing an interview, understanding the feelings of others and expressing one’s own feelings. Discussion: The dental students in the present study felt that this preclinical experiential learning session improved their communication skills. The feedback from this training experience will enable further development of an effective communication course for clinical dentistry.
