    The purpose of this study was to determine if supplementation of a high glycemic load breakfast with resistant starch attenuates the glycemic response in young healthy adults. Twenty-one subjects, 23.8 + 3.3 yrs, reported for two days of data collection, having fasted 8-12h. On day 1(control), fasting BG was measured using glucometers, then subjects consumed 2 slices white bread and 250mL apple juice within 15min, the repeated BG measurement at 15, 30, 60, 90, and 120min after baseline. Day 2, the protocol was repeated, except that 10g of resistant starch supplement was added to the apple juice. There was no significant difference in fasting BG between the data collection days. There was no significant difference in the spike in BG (difference between peak and baseline) between the control and resistant starch supplemented meal(52.6±22.7 vs 52.0±20.6mg/dL, respectively) or incremental area under the glucose curve (137.2+78.9 vs 164.0+83.2mmol/L/120min,respectively).BG peaked at 15, 30, or 60min for all subjects. The resistant starch supplement had no effect on when BG peaked after the meal. The results of this study indicate that 10g supplementation of resistant starch does not affect the spike in BG or overall glycemic response to a high glycemic load meal

    High performance alloys are often the materials used for various components exposed to high temperature environments. In many cases, protective coatings are applied in these alloys, providing higher corrosion and oxidation resistance, compared to the base material. This study investigates the feasibility to apply boro-aluminising treatment on P91 steel by pack cementation process, to increase the steel high temperature properties in oxidising and corrosive environments. Packs activated by AlCl₃, NH₄Cl and KBF₄ were used to carry out the coating deposition at a temperature of 715°C for 6 h. The coating formed was analysed by means of SEM and XRD, and the compounds formed were identified. Cyclic steam oxidation for a total of 1008 h at 650°C revealed an oxide scale of 50 mum for the uncoated P91 steel, while the coated steel shows practically no oxidation effect.Publicad

    Europe in the shadow of financial crisis: Policy Making via Stance Classification

    Get PDF
    Since 2009, the European Union (EU) is phasing a multi–year financial crisis affecting the stability of its involved countries. Our goal is to gain useful insights on the societal impact of such a strong political issue through the exploitation of topic modeling and stance classification techniques. \ \ To perform this, we unravel public’s stance towards this event and empower citizens’ participation in the decision making process, taking policy’s life cycle as a baseline. The paper introduces and evaluates a bilingual stance classification architecture, enabling a deeper understanding of how citizens’ sentiment polarity changes based on the critical political decisions taken among European countries. \ \ Through three novel empirical studies, we aim to explore and answer whether stance classification can be used to: i) determine citizens’ sentiment polarity for a series of political events by observing the diversity of opinion among European citizens, ii) predict political decisions outcome made by citizens such as a referendum call, ii) examine whether citizens’ sentiments agree with governmental decisions during each stage of a policy life cycle.

    DEVELOPMENT OF A GEOREFERENCED ARCHAEOLOGICAL INFORMATION DATA BASE FOR ELEUTHERNA IN CRETE

    [EN] Cultural Heritage Information Management Systems (CHIMS) have been developed in order to achieve the georeference of the items in the Cultural Heritage database. Eleutherna in Crete is one of the most significant archaeological sites in Greece, with. many buildings constructed and destroyed during its long life. Hence, it is easily understandable that this vast archaeological site is complicated and difficult to understand, even by experts. In this paper the development of a Cultural Heritage Management System, called ARCHAEOsystem, is described and analyzed. The system has as geographic base a recent orthophoto of the area and for its design several parameters were taken into account. The conceptual design of the data base with the Entity-Relational (E-R) model preceded the development of this object oriented system. This E-R model is described and evaluated for its operability. After the initial experimental operation of the system, eventual practical problems will be identified and confronted. Finally, presentation of future prospects is being attempted and eventual uses of such a system are proposed.Tapinaki, SI.; Georgopoulos, A.; Ioannidis, C.; Frentzos, E.; Stampolidis, N.; Maragoudakis, N.

    Ανάλυση της συμπεριφοράς του ερασιτέχνη προπονητή ποδοσφαίρου στη διαχείριση του ημιχρόνου του αγώνα.

    Σκοπός της παρούσας μελέτης ήταν να καταγραφεί και να αξιολογηθεί ο τρόπος καθοδήγησης του ερασιτέχνη προπονητή κατά τη διάρκεια του ημιχρόνου ενός ποδοσφαιρικού αγώνα. Στην έρευνα συμμετείχαν 69 ερασιτέχνες προπονητές, οι οποίοι ήταν πιστοποιημένοι από την UEFA, με διπλώματα UEFA Β (n=58) και UEFA C (n=11), ηλικίας 4110 έτη και προπονητικής εμπειρίας 11.228 έτη. Η συλλογή των δεδομένων έγινε μέσω ερωτηματολογίου, με ερωτήσεις μεικτού τύπου. Η ανάλυση έγινε με την χρήση του προγράμματος SPSS v23.0. Το 37.31% των προπονητών εργάζονταν ως επαγγελματίες προπονητές χωρίς να ασκούν παράλληλα και άλλο επάγγελμα, παρά το γεγονός ότι εργάζονταν σε ερασιτεχνικές κατηγορίες (77.22%) και ακαδημίες (15.19%) . Ο χρόνος ομιλίας των προπονητών κατά τη διάρκεια του ημιχρόνου, κυμαινόταν από 5-8’ (54.29%), ενώ ένα μεγάλο ποσοστό των ερωτηθέντων (34.29%) μιλούσαν από 9-12΄. Οι προπονητές έδιναν μεγαλύτερη έμφαση στην ομάδα τους (82.09%) σε σχέση με την αντίπαλη ομάδα (17.91%) και πιο συγκεκριμένα αναφέρονταν περισσότερο στα δυνατά της σημεία (65.22%), ενώ όταν ασχολούνταν με την αντίπαλη ομάδα, τόνιζαν τα λάθη της (79.10%). Η ποσότητα πληροφοριών που παρείχαν οι προπονητές ήταν μικρή (45.59%) εώς μέτρια (29.41%). Η ψυχολογική επίδραση διαδραμάτισε σημαντικό ρόλο ως μέσο παρακίνησης για την ανατροπή του αποτελέσματος (65.22%). Φάνηκε επίσης, ότι ο προπονητής επηρεάστηκε ελάχιστα (44.12%) ως μέτρια (30.88%) από το αποτέλεσμα του α’ ημιχρόνου. Η έρευνα αυτή παρέχει χρήσιμες πληροφορίες στους προπονητές για τον τρόπο με τον οποίο πρέπει να διαχειριστούν το ημίχρονο του αγώνα.The purpose of this study was to examine and evaluate the coaching style of the amateur coach during half time in a football match. In this study 69 amateur coach was taken part in who was been certified with UEFA B (n=58) and UEFA C (n=11) license. Data was collected through questionnaire, with mixed type questions. SPSS v23.0 fow windows was used for data analysis. The 37.31% of the coaches was worked as professional coaches despite the fact that they worked in local categories (77.22%) or in academies (15.19%). Τhe half time speech (HTS) time was between 5-8' (54.29%), while 34.29% of coaches talk for about 9-12'. Coaches emphasize in their teams (82.09%) more than the opponent team (34.29%) during HTS and especially they refer to their strong aspects (65.22%). When they refer to opponent team they focus on weak points and mistakes (79.10%). HTS volume of feedback from coaches to players was small (45.59%) to moderate (29.41%). Psychological effect plays an important role as an incentive for reversing the outcome (65.22%). Coach seems to be affected from the outcome of the first half in small (44.12%) to moderate (30.88%) rate. This research provides useful information to coaches about how they should manage the half-time in amateur football game
