description: Η Μεγάλη Ελληνική Εγκυκλοπαίδεια αποτελεί ένα πραγματικά τεράστιο και ιδιαίτερα φιλόδοξο έργο για την εποχή της (1926-34), καθώς επιδιώκει να συγκεντρώσει μέσα στους 23 τόμους της όλη την επιστημονική και ανθρώπινη γνώση και να την παρουσιάσει με αυτό και κατανοητό τρόπο στους αναγνώστες της. Η μελέτη της θρησκείας στη ΜΕΕ αντιμετωπίζεται σαν μέσο διαχωρισμού και ταξινόμησης μεταξύ των λαών και των διαφόρων ομάδων σε όλο τον κόσμο. Ο χριστιανισμός θεωρείται από τους συγγραφείς των λημμάτων ως η "ανώτερη" θρησκεία, διότι είναι η "αληθινή" και δεν ακολουθεί ψευδείς πηγές, όπως κάνουν τα άλλα θρησκεύματα ή οι άλλες λατρείες. Η αποκάλυψη του θεού στον άνθρωπο είναι ένα στοιχείο που διακρίνει και δίνει ένα προβάδισμα σε σχέση με τις άλλες θρησκείες. Παράλληλα, ο συνδυαμσός ελληνισμού και χριστιανισμού μέσα στην εγκυκλοπαίδεια συνιστούν ένα ακτύπητο δίδυμο πολιτισμού και προόδου
description: The Great Greek Encyclopaedia constitutes a really enormous and particularly ambitious work for its era (1926-34) as it seeks to assemble in 23 volumes all the scientific and human knowledge and to present it with tangible and comprehensible way in its readers. The study of religion in the CGE is faced as measn of segregation and classification between the people and the various groups in all over the world.The christianity is considered as the superior religion, because it is genuine and does not follow false sources, as other religions or other adorations do. The revelation of God in humanity is the element that distinguishes and gives a precedence concerning the other religions. At the same time, the combination of Hellenism and Christianity in the Encyclopaedia recommend a combination of culture and progress

description: All of the countries within Africa experience a serious shortage of medical professionals, particularly specialists, a problem that is only exacerbated by high emigration of doctors with better prospects overseas. As a result, those that remain in Africa, particularly those practicing in rural regions, experience a shortage of specialists and other colleagues with whom to exchange ideas. Telemedicine and teleconsultation are key areas that attempt to address this problem by leveraging remote expertise for local problems. This paper presents an overview of teleconsultation in the developing world, with a particular focus on how lessons learned apply to Africa. By teleconsultation, we are addressing non-real-time communication between health care professionals for the purposes of providing expertise and informal recommendations, without the real-time, interactive requirements typical of diagnosis and patient care, which is impractical for the vast majority of existing medical practices. From these previous experiences, we draw a set of guidelines and examine their relevance to Ghana in particular. Based on 6 weeks of needs assessment, we identify key variables that guide our framework, and then illustrate how our framework is used to inform the iterative design of a prototype system.

description: In this article, we consider the ratio of structure functions for heavy quark pair production at low values of $x$. The importance of this ratio for charm and beauty pair production is examined according to the Hadron Electron Ring Accelerator (HERA) data. The behavior of these ratios considers due to the hard-pomeron behavior of the gluon distribution function. The results are in good agreement with respect to the HERA data. Expanding this data to the range of new energies underscore the importance of these measurements for heavy quarks. The ratio of charm and beauty structure functions at the proposed Large Hadron electron Collider (LHeC) is considered as a function of invariant center-of-mass energy. For top pair production this ratio is extracted with known kinematics of the LHeC and Future Circular Collider electron-hadron (FCC-eh) colliders. Comparison of the results obtained for the ratio of top structure functions in LHeC and FCC-eh are proportional to the specified inelasticity $y$ range.

description: Mean-motion resonances (MMRs) are likely to play an important role both during and after the lifetime of a protostellar gas disk. We study the dynamical evolution and stability of planetary systems containing two giant planets on circular orbits near a 2:1 resonance and closer. We find that by having the outer planet migrate inward, the two planets can capture into either the 2:1, 5:3, or 3:2 MMR. We use direct numerical integrations of ~1000 systems in which the planets are initially locked into one of these resonances and allowed to evolve for up to ~10^7 yr. We find that the final eccentricity distribution in systems which ultimately become unstable gives a good fit to observed exoplanets. Next, we integrate ~500 two-planet systems in which the outer planet is driven to continuously migrate inward, resonantly capturing the inner; the systems are evolved until either instability sets in or the planets reach the star. We find that although the 5:3 resonance rapidly becomes unstable under migration, the 2:1 and 3:2 are very stable. Thus the lack of observed exoplanets in resonances closer than 2:1, if it continues to hold up, may be a primordial signature of the planet formation process.

description: Computer-mediated communication systems can be used to bridge the gap between doctors in underserved regions with local shortages of medical expertise and medical specialists worldwide. To this end, we describe the design of a prototype remote consultation system intended to provide the social, institutional and infrastructural context for sustained, self-organizing growth of a globally-distributed Ghanaian medical community. The design is grounded in an iterative design process that included two rounds of extended design fieldwork throughout Ghana and draws on three key design principles (social networks as a framework on which to build incentives within a self-organizing network; optional and incremental integration with existing referral mechanisms; and a weakly-connected, distributed architecture that allows for a highly interactive, responsive system despite failures in connectivity). We discuss initial experiences from an ongoing trial deployment in southern Ghana.

description: We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr M1 star AU Microscopii (Au Mic) collected with the high-resolution $YJHK$ (0.98-2.35 $μ$m) spectropolarimeter SPIRou from 2019 September 18 to November 14. Our radial velocity (RV) time-series exhibits activity-induced fluctuations of 45 m/s RMS, about three times smaller than those measured in the optical domain, that we filter using Gaussian Process Regression. We report a 3.9$σ$-detection of the recently-discovered 8.46-d transiting planet AU Mic b, with an estimated mass of $17.1^{+4.7}_{-4.5}$ M$_{\odot}$ and a bulk density of $1.3 \pm 0.4$ g/cm$^{-3}$, inducing a RV signature of semi-amplitude $K=8.5^{+2.3}_{-2.2}$ m/s in the spectrum of its host star. A consistent detection is independently obtained when we simultaneously image stellar surface inhomogeneities and estimate the planet parameters with Zeeman-Doppler Imaging (ZDI). Using ZDI, we invert the time series of unpolarized and circularly-polarized spectra into surface brightness and large-scale magnetic maps. We find a mainly poloidal and axisymmetric field of 475 G, featuring, in particular, a dipole of 450 G tilted at 19° to the rotation axis. Moreover, we detect a strong differential rotation of d$Ω= 0.167 \pm 0.009$ rad/d shearing the large-scale field, about twice stronger than that shearing the brightness distribution, suggesting that both observables probe different layers of the convective zone. Even though we caution that more RV measurements are needed to accurately pin down the planet mass, AU Mic b already appears as a prime target for constraining planet formation models, studying the interactions with the surrounding debris disk, and characterizing its atmosphere with upcoming space- and ground-based missions.

description: The basic parameter that determines the ways for measuring physical situation in training conditions is heart-rate frequency records me assuring heart - rate is as important at training as during the game. The purpose of this study was to measure the heart - rate on football players in actual match and its comparative results among different places a footballer takes on systems 3-5-2 and 4-4-2 .For the needs of this study have been selected two offensive players ,two middle side players and two defensive players .We have record five matches with system 3-5-2 and five matches with system 4-4-2. Polar sport Tester 610 was used for measuring heart-rate. Classification of heart-rate measurement according to maximum heart-rate was divided in levels for better results. Range analysis ANOVA was used to examining the different rates of maximum heart-rate per place and systems. As a result, statistically differences were not found in average heart-rate. Never less offensive and middle side players had higher heart-rate of the defensive ones.

description: Context: AXJ1845.0-0433 was discovered by ASCA in 1993 during fast outburst activity characterized by several flares on short timescales. Up to now, the source was not detected again by any X-ray mission. Its optical counterpart is suggested to be an O9.5I supergiant star, which is the only remarkable object found inside the ASCA error box. Aims: To detect and characterize new fast outbursts of AXJ1845.0-0433 and confirm its supergiant HMXB nature, using INTEGRAL and archival Swift XRT observations. Methods: We performed an analysis of INTEGRAL IBIS and JEM-X data with OSA 5.1 as well as an analysis of archive Swift XRT data. Results: We report on fast flaring activity from the source on timescales of a few tens of minutes, the first to be reported since its discovery in 1993. Two outbursts have been detected by INTEGRAL (Apr 2005 and Apr 2006) with similar peak fluxes and peak luminosities of 80 mCrab and 9.3X10^35 erg s^-1 (20--40 keV), respectively. Two other outbursts were detected by Swift XRT on Nov 2005 and Mar 2006. The refined Swift XRT position of AXJ1845.0-0433 confirms its association with the supergiant star previously proposed as optical counterpart. Conclusions: Our INTEGRAL and Swift results fully confirm the supergiant HMXB nature of AXJ1845.0-0433 which can therefore be classified as a supergiant fast X-ray transient. Moreover they provide for the first time evidence of its recurrent fast transient behaviour.

description: The present thesis tries to highlight a line of Religious Tourism in the ports of the Black Sea and Northern Greece. Considering that the Black Sea countries are almost entirely Orthodox (Russia, Ukraine, Romania, Bulgaria) and Istanbul is the seat of the Ecumenical Patriarchate, the diplomatic work aims to connect the ports of these countries with the focus on Religious Tourism and the preservation of cultural heritage. We will therefore study port cities by highlighting the history, the ports and especially the monuments of religious tourism, the elements that make up the cultural image of a place.

description: Revealing the cosmic reionisation history is at the frontier of extragalactic astronomy. The power spectrum of the cosmic microwave background (CMB) polarisation can be used to constrain the reionisation history. Here we propose a CMB-independent method using fast radio bursts (FRBs) to directly measure the ionisation fraction of the intergalactic medium (IGM) as a function of redshift. FRBs are new astronomical transients with millisecond timescales. Their dispersion measure (DM$_{\rm IGM}$) is an indicator of the amount of ionised material in the IGM. Since the differential of DM$_{\rm IGM}$ against redshift is proportional to the ionisation fraction, our method allows us to directly measure the reionisation history without any assumption on its functional shape. As a proof of concept, we constructed mock non-repeating FRB sources to be detected with the Square Kilometre Array, assuming three different reionisation histories with the same optical depth of Thomson scattering. We considered three cases of redshift measurements: (A) spectroscopic redshift for all mock data, (B) spectroscopic redshift for 10% of mock data, and (C) redshift estimated from an empirical relation of FRBs between their time-integrated luminosity and rest-frame intrinsic duration. In all cases, the reionisation histories are consistently reconstructed from the mock FRB data using our method. Our results demonstrate the capability of future FRBs in constraining the reionisation history.

description: Social distancing as one of the main non-pharmaceutical interventions can help slow down the spread of diseases, like in the COVID-19 pandemic. Effective social distancing, unless enforced as drastic lockdowns and mandatory cordon sanitaire, requires consistent strict collective adherence. However, it remains unknown what the determinants for the resultant compliance of social distancing and their impact on disease mitigation are. Here, we incorporate into the epidemiological process with an evolutionary game theory model that governs the evolution of social distancing behavior. In our model, we assume an individual acts in their best interest and their decisions are driven by adaptive social learning of the real-time risk of infection in comparison with the cost of social distancing. We find interesting oscillatory dynamics of social distancing accompanied with waves of infection. Moreover, the oscillatory dynamics are dampened with a nontrivial dependence on model parameters governing decision-makings and gradually cease when the cumulative infections exceed the herd immunity. Compared to the scenario without social distancing, we quantify the degree to which social distancing mitigates the epidemic and its dependence on individuals' responsiveness and rationality in their behavior changes. Our work offers new insights into leveraging human behavior in support of pandemic response.

description: Thermal comfort assessment for the built environment has become more available to analysts and researchers due to the proliferation of sensors and subjective feedback methods. These data can be used for modeling comfort behavior to support design and operations towards energy efficiency and well-being. By nature, occupant subjective feedback is imbalanced as indoor conditions are designed for comfort, and responses indicating otherwise are less common. This situation creates a scenario for the machine learning workflow where class balancing as a pre-processing step might be valuable for developing predictive thermal comfort classification models with high-performance. This paper investigates the various thermal comfort dataset class balancing techniques from the literature and proposes a modified conditional Generative Adversarial Network (GAN), $\texttt{comfortGAN}$, to address this imbalance scenario. These approaches are applied to three publicly available datasets, ranging from 30 and 67 participants to a global collection of thermal comfort datasets, with 1,474; 2,067; and 66,397 data points, respectively. This work finds that a classification model trained on a balanced dataset, comprised of real and generated samples from $\texttt{comfortGAN}$, has higher performance (increase between 4% and 17% in classification accuracy) than other augmentation methods tested. However, when classes representing discomfort are merged and reduced to three, better imbalanced performance is expected, and the additional increase in performance by $\texttt{comfortGAN}$ shrinks to 1-2%. These results illustrate that class balancing for thermal comfort modeling is beneficial using advanced techniques such as GANs, but its value is diminished in certain scenarios. A discussion is provided to assist potential users in determining which scenarios this process is useful and which method works best.

description: In jet quenching, a hard QCD parton, before fragmenting into a jet of hadrons, deposits a fraction of its energy in the medium, leading to suppressed production of high-$p_T$ hadrons. The process can generate shock waves. We study the distortion of Mach shock waves due to jet quenching in central Au+Au collisions and its effect on particle production. Finite fluid velocity and inhomogeneity of the medium can distort the Mach shock front significantly such that the inside shock front disappear and the outside shock front is opened up. We also show that the STAR data on azimuthal distribution of background subtracted secondaries, associated with high $p_T$ trigger, are reasonably well explained by the excess pions produced due to partonic energy loss.

ELSA: an intelligent multisensor integration architecture for industrial grading tasks
Creators: name: Naish, Michael David
Publisher: name: University of British Columbia
Year: 2009

description: The Extended Logical Sensor Architecture (ELSA) for multisensor integration has been developed for industrial applications, particularly, the on-line grading and classification of non-uniform food products. It addresses a number of issues specific to industrial inspection. The system must be modular and scalable to accommodate new processes and changing customer demands. It must be easy to understand so that non-expert users can construct, modify, and maintain the system. The object model used by ELSA is particularly suited to the representation of non-uniform products, which do not conform to an easily specified template. Objects are represented by a connected graph structure; object nodes represent salient features of the object. Object classifications are defined by linking to primary features, each primary feature may be composed of a number of lower-level subfeatures. Sensors and processing algorithms are encapsulated by a logical sensor model, providing robustness and flexibility. This is achieved by separating sensors from their functional use within a system. The hierarchical structure of the architecture allows for modification with minimal disturbance to other components. The construction methodology enables domain experts, who often lack signal processing knowledge, to design and understand a sensor system for their particular application. This is achieved through a formal design process that addresses functional requirements in a systematic way. Each stage involves the extraction and utilization of the user's expert knowledge about the process and desired outcomes. Specification of the requirements leads to the identification of primary features and object classifications. Primary features are expanded into subfeatures. Logical sensors are then chosen to provide each of the features defined by the object model; this in turn determines what physical sensors are required by the system. The object classifications determine the rulebase used by the inference engine to infer process decisions.

description: In recent development of quantum technologies, a frequency conversion of quantum signals has been studied widely. We investigate the optic-microwave entanglement that is generated by applying an electro-optomechanical frequency conversion scheme to one mode in an optical two-mode squeezed vacuum state. We quantify entanglement of the converted two-mode Gaussian state, where surviving entanglement of the state is analyzed with respect to the parameters of the electro-optomechanical system. Furthermore, we show that there exists an upper bound for the entanglement that survives after the conversion of highly entangled optical states. Our study provides a theoretical platform for a practical quantum illumination system.

description: Understanding the linear or nonlinear relationship between load and deformation in structural materials or structural frames is a key to a proper and a well-represented simulation. This research is dedicated to model a cyclic load-deformation hysteresis relationship, captured from experimental results, and utilize it to represent the cyclic hysteresis data. The Genetic Algorithm is used to find the best parameters to introduce the model and to minimize the deviation between the simulation and the experimental results. In other words, the parameters associated with the loading response of any displacement pattern, are found, while minimizing the deviation between simulation loading response and the loading data carried out from the experiment. First, to reduce the data size recorded with measuring devices or Linear Variable Differential Transformers (LVDTs in short), a data resampling technic is proposed. Second, the resampled data is used in Genetic Algorithm to seek for the best parameters to describe the model. This method could be used to train models to predict the capacity and performance of a materials and frames when they are exposed to any deformation patterns. Numerous examples are shown at the end of the paper.
Elucidating the role of Insulin/IGF-like signalling in the response of lifespan to dietary restriction in Drosophila melanogaster

Insulin/IGF-like signalling
Drosophila melanogaster

description: MutaDons within the insulin/IGF-like signalling (IIS) pathway have been
 shown to influence lifespan in model organisms such as Caenorhabdi;s
 elegans, Drosophila melanogaster, and Mus musculus. Specifically,
 reducDons in IIS, both systemic and Dssue-specific, have been associated
 with increased lifespan, however some modulaDons have negaDvely impacted
 healthspan, including reproducDve and behavioural health. In parDcular,
 the pan-neural reducDon of IIS negaDvely affects the senescence of
 exploratory walking and negaDve geotaxis in Drosophila despite extending
 lifespan. The pan-neural effects of IIS reducDon were hypothesised to be
 the sum of the posiDve, negaDve, and neutral effects of reduced IIS within
 individual neuronal subtypes and recent research supports this hypothesis.
 One recent study found that reducing IIS in specific neuronal subtypes in
 Drosophila resulted in varying effects on lifespan and locomotor
 senescence. Reducing IIS in serotonergic neurons was the only modulaDon
 invesDgated capable of extending lifespan, and it did so without negaDvely
 impacDng locomotor senescence. This project addresses two hypotheses: 1)
 the response to dietary restricDon involves insulin/IGF-like signalling in
 serotonergic neurons and therefore the response of flies with reduced IIS
 in serotonergic neurons will be reduced; and 2) reducing IIS in
 serotonergic neurons will alter serotonergic signalling to the IPCs
 resulDng in altered DILP expression and/or secreDon. To address these
 hypotheses, we used survival assays with standard, dietary restricDon,
 fully fed, and low nutrient (0.1 x yeast) food condiDons,
 immunohistochemical analysis of proteins in fly brains, and qPCR of fly
 heads. We also invesDgated other behaviours and phenotypes which could
 have been influenced by reduced serotonergic IIS including oxidaDve stress
 resistance, starvaDon resistance, negaDve geotaxis, feeding behaviour, and
 fecundity. The results showed that reduced serotonergic IIS increased
 lifespan in females on DR and SY diets and increased the lifespan of males
 on 0.1% yeast starvaDon and FF diets. No negaDve effects of reduced
 serotonergic IIS on stress resistance, negaDve geotaxis, or female
 fecundity were observed. AddiDonally, DILP2 and DILP5 expression was not
 altered in females with reduced serotonergic IIS, however, serotonin was.
 Together, the data suggest that the lifespan extension observed in females
 is likely not due to a modulaDon of the insulin producing cells (IPCs) and
 could be the result of altered serotonin signalling, however, further
 research is needed to determine the exact mechanism.

description: Ερευνες στη δεκαετία του 80 έχουν διαπιστώσει ότι τα νέα άτομα που ένιωθαν ότι η επιστήμη που σπούδαζαν δεν ταίριαζε στα χαρακτηριστικά και τους ρόλους του φύλου τους, δεν επιθυμούσαν να ασκήσουν επαγγέλματα σχετικά με αυτή την επιστήμη. Αυτή η διαπίστωση αφορούσε συγκεκριμένα τα κορίτσια από το χώρο των θετικών επιστημών. Λαμβάνοντας υπόψιν τις αλλαγές που έχουν σημειωθεί από τότε στα φύλα και την εκπαίδευσή τους, η εργασία αυτή εστιάζει στην Ανώτατη Εκπαίδευση και εξετάζει τη σχέση που υπάρχει ανάμεσα στην ταυτότητα του φύλου των φοιτητών και φοιτητριών και στο αντικείμενο σπουδών του, καθώς και στην επίδραση που αυτή ασκεί στα επαγγελματικά τους σχέδια. Χρησιμοποιώντας δείγμα 26 φοιτητών και φοιτητριών και τη μέθοδο των ομαδικών συνεντεύξεων εστίασης, η παρούσα έρευνα καταλήγει στο γενικό συμπέρασμα ότι για όλα τα υποκείμενα της έρευνας, το φύλο τους είναι συμβατό, ταιριάζει με την επιστήμη τους και επιθυμούν να ακολουθήσουν και το σχετικό με αυτή επάγγελμα. Ακόμα και οι φοιτήτριες από τις θετικές επιστήμες και τις τεχνολογίες δεν αναφέρουν κάποια ασυμβατότητα ή σύγκρουση ανάμεσα στα χαρακτηριστικά του φύλου τους και στα χαρακτηριστικά αυτών των επονομαζόμενων "ανδρικών" επιστημών
description: Research in the 80s has shown that young people who felt that their subject of study did not match the characteristics and roles of their gender, did not wish a career related to this subject. This applied, in particular, to girls in science. Taking into consideration the changes that took place in both sexes and their education since then, this study focuses on Higher education and examines the relationship between students gender identity and their subject as well as its influence on their occupational plans. Using a sample of 26 male and female students and the method of focus groups interviews, the present study concludes with a general inference : all respondents feel that their gender is compatible with their subject and they wish to follow a relevant occupational path. Even the female students in science and technologies do not mention any incompatibility or conflict between their gender characteristics and the characteristics or these s0-called masculine subjects

description: One of the major and unfortunately unforeseen sources of background for the current generation of X-ray telescopes are few tens to hundreds of keV (soft) protons concentrated by the mirrors. One such telescope is the European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton). Its observing time lost due to background contamination is about 40\%. This loss of observing time affects all the major broad science goals of this observatory, ranging from cosmology to astrophysics of neutron stars and black holes. The soft proton background could dramatically impact future large X-ray missions such as the ESA planned Athena mission (http://www.the-athena-x-ray-observatory.eu/). Physical processes that trigger this background are still poorly understood. We use a Machine Learning (ML) approach to delineate related important parameters and to develop a model to predict the background contamination using 12 years of XMM observations. As predictors we use the location of satellite, solar and geomagnetic activity parameters. We revealed that the contamination is most strongly related to the distance in southern direction, $Z$, (XMM observations were in the southern hemisphere), the solar wind radial velocity and the location on the magnetospheric magnetic field lines. We derived simple empirical models for the first two individual predictors and an ML model which utilizes an ensemble of the predictors (Extra Trees Regressor) and gives better performance. Based on our analysis, future missions should minimize observations during times associated with high solar wind speed and avoid closed magnetic field lines, especially at the dusk flank region in the southern hemisphere.

description: Σκοπός της παρούσας έρευνας είναι να ανιχνεύσει τις διατροφικές συνήθειες των μαθητών - μαθητριών ηλικίας 11-12 ετών, τις γνώσεις που έχουν πάνω στην υγιεινή διατροφή και στα προγράμματα άθλησης, τη συμπεριφορά τους απέναντι στις υγιείς διατροφικές συνήθειες και τη συμμετοχή τους σε αθλητικές δραστηριότητες. Στην έρευνα συμμετείχαν 268 μαθητές και μαθήτριες 11 - 12 ετών από οχτώ δημοτικά σχολεία της επαρχίας του νομού Θεσσαλονίκης. Τα αποτελέσματα έδειξαν ότι τα παιδιά του δείγματος έχουν αρκετές γνώσεις πάνω στην υγιεινή διατροφή. Υπήρξε θετική συσχέτιση μεταξύ των γνώσεων στην υγιεινή διατροφή και των υγιών διατροφικών συνηθειών, καθώς επίσης μεταξύ της συμμετοχής σε προγράμματα άθλησης και των υγιών διατροφικών συνηθειών.Είναι απαραίτητο λοιπόν να εκτιμηθεί η σπουδαιότητα της διατροφικής αγωγής, με την ένταξή της στο βασικό εκπαιδευτικό πρόγραμμα. Η συνεργασία οικογένειας, σχολείου και Πολιτείας θα συμβάλει στην αποτελεσματική ανάπτυξη υγιών τρόπων συμπεριφοράς.
description: The aim of the present study is to detect the dietary habits of students between 11 and 12 years old, the knowledge that they have on the healthy eating and the programmes of physical activity, their attitude to healthy habits and their participation in athletic activities. 268 students participated in the research of 11 - 12 years from eight provincial elementary schools of Thessaloniki. The results showed that the sampled children have enough knowledge of healthy eating. A positive correlation existed between their knowledge of healthy eating and healthy dietary habits, also between the attendance in programs of physical activity and healthy dietary habits.It is essential therefore to assess the importance of nutritional education, and its integration to a basic educational programme. The collaboration of family, school and State will contribute in the effective growth of healthy ways of behaviour.

description: We discuss an approach for studying the properties of mesoscopic systems, where discrete and continuum parts of the spectrum are equally important. The approach can be applied (i) to stable heavy nuclei and complex atoms near the continuum threshold, (ii) to nuclei far from the region of nuclear stability, both of the regions being of great current interest, and (iii) to mesoscopic devices with interacting electrons. The goal is to develop a new consistent version of the continuum shell model that simultaneously takes into account strong interaction between fermions and coupling to the continuum. Main attention is paid to the formation of compound resonances, their statistical properties, and correlations of the cross sections. We study the Ericson fluctuations of overlapping resonances and show that the continuum shell model nicely describes universal properties of the conductance fluctuations.

Ωστόσο, ο εφαρμοστής του δικαίου, κατά το δικαστικό έλεγχο της συνταγματικότητας των νόμων, οφείλει να συμπροσδιορίζει το νόημα μιας διάταξης του εθνικού Συντάγματος με αναφορά στο νομικό οικοδόμημα της Ευρωπαϊκής Σύμβασης των Δικαιωμάτων του Ανθρώπου.
description: In most court judgements related to issues concerning the protection of prorerty rights, it seems that judges are reluctant to interpret Article 17 of the greek Constitution according to Article 1 of the First Protocole of the ECHR. Article 17 of the greek Constitution doesn't protect property rights and the only protection offered is from the ECHR. However, judges should define the meaning of a constitutional article in relation to the legal order of the ECHR in order to enrich its interpretation and provide further protection.
