description: Η παρούσα βιβλιογραφική μελέτη ασχολείται τόσο με τις παραδοσιακές όσο και με τις εναλλακτικές μορφές αξιολόγησης που πραγματοποιούνται κατά τη διάρκεια της εκπαιδευτικής πράξης. Επίσης, διερευνάται κατά πόσο αυτές οι μορφές μπορούν να εφαρμοστούν στην εξ αποστάσεως εκπαίδευση. Το κύριο μέρος της εργασίας επικεντρώνεται στη διερεύνηση μιας μελέτης. Για τον λόγο αυτό απομονώνεται η συγκεκριμένη μελέτη και σε πρώτη φάση εξετάζονται αναλυτικά προγράμματα από είκοσι τέσσερα διαδικτυακά μαθήματα, προκειμένου να διαπιστωθούν τα είδη αξιολόγησης που χρησιμοποιούνται στα μαθήματα και να αποκτηθεί μια αίσθηση του επιπέδου συνεισφοράς κάθε τύπου στη συνολική βαθμολογία του μαθήματος. Στη δεύτερη φάση, οκτώ από τους εκπαιδευτικούς συμμετέχουν είτε σε μια ομάδα εστίασης είτε σε μια συνέντευξη ένας προς έναν για να συζητήσουν τις προκλήσεις αξιολόγησης που αντιμετωπίστηκαν κατά τη μεταφορά των μαθημάτων τους στο διαδίκτυο και αποτελεσματικές πρακτικές που αναπτύχθηκαν για να αντιμετωπίσουν αυτές τις προκλήσεις. Τελικά, μέσα από την μελέτη της εργασίας και την σύγκριση των τεχνικών που χρησιμοποιούνται και στις δύο μορφές αξιολόγησης διαπιστώνεται η καταλληλότητα τους καθώς και η συμβολή τους σε μια εξ αποστάσεως διδασκαλία.

description: The present study addresses both the traditional and alternative forms of educational assessment, which take place during the educational process. It also examines whether these forms of education can be applied to distance education. The main part of this study focuses on the exploration of another study, in which syllabi from twenty four online courses are examined. The purpose is to find out the forms of assessment which are being used in the aforementioned courses and to obtain a sense of each form’s contribution in the overall grades of the course. In the second phase, eight of the teachers participate in either a focus group or a one-on-one interview, in order to discuss the assessment challenges they faced during the transfer of their courses online and any effective practices they developed to address those challenges. Finally, through the examination of the study and the comparison of the techniques used in both forms of assessment, their suitability as well as their contribution to distance learning is ascertained.

description: Οι Ανανεώσιμες Πηγές Ενέργειας, σε αντίθεση με τις συμβατικές, είναι ανεξάντλητες, δεν αφήνουν κατάλοιπα ή απόβλητα και βοηθούν στην ενεργειακή απεξάρτηση και αυτονομία. Από την άλλη πλευρά όμως, λόγω της στοχαστικότητας που τις διακρίνουν, έχουν μικρότερη απόδοση σε σύγκριση με τα ορυκτά καύσιμα και η παραγωγή τους εξαρτάται από τις διακυμάνσεις των φυσικών φαινομένων. Παρόλα αυτά, οι Ανανεώσιμες Πηγές Ενέργειας αξιοποιούνται ολοένα και περισσότερο σε παγκόσμια κλίμακα και για τον λόγο αυτό θεσπίζονται πολιτικές και δράσεις που στηρίζουν και ενισχύουν την ανάμειξη των ιδιωτών και των επιχειρήσεων σε αυτές. Με τη χρήση ερωτηματολογίου, η παρούσα μελέτη αποτυπώνει την άποψη των πολιτών για τις Ανανεώσιμες Πηγές Ενέργειας στην Ελλάδα. Εξετάζεται η ευαισθητοποίηση τους προς το περιβάλλον και την κλιματική αλλαγή, σε σχέση με την περαιτέρω ανάπτυξη των Ανανεώσιμων Πηγών Ενέργειας. Τέλος, τα εμπειρικά αποτελέσματα αποτυπώνουν την πρόθεση των πολιτών να ενισχύσουν περαιτέρω τις Ανανεώσιμες Πηγές ή ακόμα και να επενδύσουν σε αυτές.
description: Renewable Energy Sources, unlike conventional ones, are inexhaustible, no residue or waste and help in energy detoxification and autonomy. On the other hand, due to the thoughtfulness that distinguishes them, they have a lower efficiency compared to fossil fuels and their production depends on the fluctuations of natural phenomena. Nevertheless, Renewable Energy Sources are increasingly used worldwide and for this reason, policies and actions have been established that support and enhance the involvement of individuals and companies in them. Using a questionnaire, this study reflects the opinion of citizens about Renewable Energy Sources in Greece. Their awareness of the environment and climate change in relation to the further development of Renewable Energy Sources is examined. Finally, the empirical findings reflect the intention of the citizens to further strengthen the Renewable Sources or even to invest in them.

description: In recent times river pollution is a serious and growing problem in most developing countries. Industrial effluents and sewage entering the water bodies are one of the major sources of environmental toxicity, which endangers aquatic biota and deteriorates water quality. Biological methods for the removal of heavy metals from industrial waste may provide an attractive alternative to the physicochemical process. Biosurfactants are one of the compounds that help in alleviating the heavy metals. A large number of bacteria such as Bacillus sp., Pseudomonas sp., Acinetobacter sp. and Arthrobacter sp. are reported to produce biosurfactants. Compared to synthetic compounds, biosurfactants provide the advantages of little or no environmental impact and the possibility of in-situ production. Studies in recent past have exhibited the successful use of biosurfactants for facilitating the degradation of organic pollutants in soil and water. In the light of the above, the present study is aimed to carry out the assessment of efficiency of biosurfactants producing bacteria isolated from heavy metal contaminated site of the river Ganga. The bacterial isolates (PGS1, PGS2 and PGS3) were screened belonging to the genus Pseudomonas were found to remove heavy metals from the medium. The isolate PGS1 was found to be more effective in removing more than 50% chromiumand cadmium fromthe medium.

description: Dairy production effectiveness in the farm depends on many technical, technological and biological factors. State of the dairy cow condition constitutes one of the most important element in the assessment of dairy herd and production indices. Including access to modern technical solution to assess body condition of dairy cows, i.e. BCS camera, some results of observation in the herd with 362 cows were collected to find any relationship between BCS index and milk yield per cow including 5 lactation groups and cows differed in age as well as four seasons. Basing on data collected in the period of 11 months it was found that cows with the BCS index lower than 2.9 showed the highest daily milk production. Increase in BCS index was associated with decrease in amount of produced milk per day. The statistical analysis showed significant effect of lactation period, age of animals and season on BCS results in the considered dairy cow production cycle.

description: Pig livestock farming systems encounter several economic and environmental challenges, connected with meat price decrease, sanitary norms, emissions etc. To deal with these issues, methods and models to assess the performance of a pig production system have been developed. For instance, Thermipig model represents the pig fattening room and simulates performances of pigs at the batch level, taking into account interactions between the individual variability of pigs, farmer's practices, room characteristics and outdoor climate conditions. The model requires some static basic inputs fulfilled in several spreadsheets (such as rooms, pigs, and dietary characteristics) but also data files for voluminous variable inputs (such as outdoor temperature or climate control box parameters) for further modelling and outcome producing. This leads to challenges in data providing by the farmers and have to be improved. This paper deals with the implementation of the separate modules of the developed data warehouse system for usability improvements of the Thermipig model. The idea is to substitute input from the data files with online data input and automated variable processing by the model using the python script for connection to the remote data warehouse. The data warehouse system is extended with ‘Property Sets’ section dealing with all the operations that can be performed to a set of input variables. This approach demonstrates the ability of the data warehouse to act as data supplier for the remote model. As well the outcome of the model is also transferable back to the data warehouse for evaluation. This work is done within the Era-Net SuSan PigSys project - Improving pig system performance through a whole system approach.

description: In this thesis we use quartz tuning fork resonators to probe properties of normal and superfluid 4He and 3He. Our main goal is to study both quantum turbulence and acoustic emission of tuning forks in liquid helium. By employing a multi-frequency lock-in amplifier we contrast single and multi- frequency methods of measuring tuning forks in the linear regime. In the non-linear response of tuning forks during turbulence we create multi-frequency excitations called intermodulation products which are used to find the non-linear forces that created them. We apply this technique to quantum turbulence in superfluid 4He-II and find that the retarding in-phase force on the fork increases at a critical velocity for turbulence nucleation. We also observe that the out-of-phase non-linear force increases, which we attribute to energy loss via vortex ring emission by the fork. Superfluid 3He is a fermionic condensate of Cooper pairs of 3He atoms. At ultra-low temperatures of 120 μK thermally excited unpaired quasiparticles travel ballistically through the condensate. We beam quasiparticles from a black body source towards a 5 × 5-pixel camera and observe that the excitations follow photonic-like trajectories. We apply the source-camera configuration to non-invasively detect and even image quantum vortices, that are topological defects in the superfluid. Lastly, we explore the frequency dependent damping of quartz tuning forks in liquid 3He. We find that at high frequencies the fork damping is governed by acoustic emission. Furthermore, we show that existing models developed for sound emission in 4He can be used to predict observed acoustic damping in 3He. The results also suggest that devices for 3He experiments should be placed in cavities or designed to operate at low frequencies.

Η μελέτη αυτή θα επιτευχθεί μέσω της θρησκειολογικής προσέγγισης από κοινού με τη μελέτη των αρχαιολογικών ευρημάτων. Αρχικά, θα παρουσιαστεί η σύνδεση της θεάς με τους σκύλους καθώς και οι αναφορές σε θυσίες σκύλων που τελούνταν προς τιμήν της. Έπειτα, θα καταγραφούν όλα τα στοιχεία που αναδεικνύουν την Εκάτη ως αστρική θεότητα και θα τονιστεί ο ρόλος της ως σημαντικής θεάς των Ελευσίνιων Μυστηρίων. Επιπλέον, θα εξετασθεί η παράδοση που καλλιεργήθηκε για τις δυνάμεις που ασκούσε ο Σείριος, ήδη από την ομηρική εποχή, μέχρι και τους ρωμαϊκούς χρόνους. Συγκεκριμένα, θα μελετηθεί η τοπική λατρεία του Σειρίου στη νήσο Κέα, οι πηγές που αναφέρουν θυσίες προς το άστρο καθώς και η ένωση της συγκεκριμένης λατρείας με την αντίστοιχη λατρεία του Σειρίου στην Αίγυπτο. Στο τέλος θα επιχειρηθεί να γίνει σύγκριση των ομοιοτήτων μεταξύ αυτών των θεοτήτων, ως προς τα κοινά χαρακτηριστικά τους, μέσω των οποίων γίνεται εφικτή η σύνδεση της λατρείας της Εκάτης με τη λατρεία του Σειρίου, όπως αυτές εκφράστηκαν κατά την ύστερη αρχαιότητα.
description: In the present master’s thesis, the worship of Hecate as an astral and chthonic deity is studied and its correlation with the worship of Sirius in the Greco-Roman area. This study will be accomplished through the religious approach together with the study of archaeological findings. Initially, the goddess’s association with the dogs will be presented as well as references to dog sacrifices performed in her honor. Then, all the elements that highlight Hecate as an astral deity will be recorded and her role as an important goddess of the Eleusinian Mysteries will be emphasized. Furthermore, the tradition which was cultivated for the power exercised by Sirius, from Homeric era, up to Roman times, will be examined. Specially, the local cult of Sirius on the island of Kea, the sources that mention sacrifices to the star, as well as the union of this cult with the corresponding cult of Sirius, will be examined. In the end, an attempt will be made to compare the similarities between these deities, in terms of their common characteristics, through which it is possible to connect the worship of Hecate with the worship of Sirius, as they were expressed in late antiquity.

description: Ce travail de mémoire présente une analyse de cas portant sur les règles de vie qui prennent place à l’école. Respecter le travail des autres, prendre soin du matériel, ne pas couper la parole, écouter les autres : ces quelques exemples non exhaustifs de comportements attendus de la part des élèves, représentent les enjeux qui se trouvent derrière les règles de vie mises en place dans l’univers scolaire par les enseignantes. Elles participent à la forme scolaire et les élèves doivent les acquérir dès leurs premières années de scolarité. Cet apprentissage ne peut se faire sans une médiation enseignante dans le but d’enseigner à la fois leur application et leur compréhension. L’objectif sous-jacent est de créer un climat de classe propice aux apprentissages, puis de manière plus large enseigner la citoyenneté aux élèves. L’utilisation de médiateurs pour accompagner cet apprentissage peut se faire sous diverses formes. Cependant, elle doit être réfléchie à l’avance par les enseignantes dans le but d’éviter des malentendus cognitifs qu’ils sont susceptibles de créer chez les élèves. La manière de présenter les règles de vie via des médiateurs aux élèves, ainsi que la manière de les utiliser sont l’objet de ce travail de mémoire. Pour réaliser cette analyse de cas, nous avons récolté diverses données auprès d’une enseignante et ses élèves durant un semestre dans une classe de stage de 1-2H. Les nombreuses observations en classe nous permettent de rendre compte des pratiques de l’enseignante que nous mettons en lien avec son discours lors de l’entretien ainsi qu’avec le discours des élèves. Ce travail consiste en une analyse d’un fonctionnement de classe qui est propre à une enseignante mais qui permet de questionner de manière plus globale l’utilisation des médiateurs. Ce travail amène des apports et des questionnements qui nous sont utiles dans notre future pratique d‘enseignante et nous permet de nous positionner.

description: Animal waste products, manure, in particular, are the sources of gases harmful to human and animal health. Hydrogen sulfide (H2S), which is produced from the breakdown of organic matter in animal faeces, is one of them. Its concentration in the cow barn air should not exceed 5 mg m−3 . A special laboratory setup was designed and the level of hydrogen sulfide emissions from the cow manure was determined depending on the time and manure temperature and moisture content. The most intensive emission of hydrogen sulfide from manure was in the first 24 hours – the increment of H2S concentration was 0.168 mg m−3 per hour average. During the next 24 hours, it was 0.021 mg m−3 per hour. When the manure temperature increased, H2S concentration increased also; when the temperature manure decreased, H2S concentration decreased also. In 48 hours, the hydrogen sulfide concentration was 1.1 mg m−3 at the manure temperature of +3.0 °C. At the manure temperature of +23.4 °C and 21.3 °C, H2S concentration was 6.53 mg m−3 and 4.97 mg m−3 , respectively. The higher was the manure moisture content, the lower was the emission of hydrogen sulfide into the environment. After 24 hours under the manure moisture content of 88.5% and 92.5% and its temperature of 21 °С ± 0.3 °С, the difference in the hydrogen sulfide concentration was 1.18 times depending on the manure moisture content. The selected regression equations described the dependence of the hydrogen sulfide concentration on the considered factors. The determination coefficients and Student's criteria proved the reliability of the results obtained at the significance level P ≤ 0.05.

description: The aim of this study was to study the effect of the sugar dosage, improver dosage, type of bread making methods and the amylolytic activity of five different types of wheat flours on the sugar content and the bread quality. The sugar content in the bread crumb was determined using the Bertrand’s method and was counted for sucrose. When the dough was prepared using accelerated technology, the improver affected the sugar content in the bread due to the starch enzymatic hydrolysis. The effect of improver dosages and sugar dosages on the sugar content in the bread was established. When using the improver, the sugar content exceeded the permitted amount in 1.25 times. No correlation was found between sugar dosage in recipe and bread quality when accelerated bread making way was used because of short fermentation time. The influence of wheat flour amylolytic activity (falling number) on the sugar content in bread was established, including when sugar was absent in the formulation. When sugar presented at bread formulation, the flour amylolytic activity did not significantly affect the bread quality, except the acidity. The bread making way had a greater influence on bread quality than falling number of flour. When sugar absent at bread recipe, the higher was the flour amylolytic activity, the higher was the sugar content in bread made by traditional way due to the starch deterioration. Obtained data have shown that when a baking method is selected, the flour amylolytic activity must be taken into account.

Συγκεκριμένα μελετήθηκαν δείγματα από οκτώ άτομα που είχαν υποστεί ταφική πυρά (καύση) και 39 άτομα που είχαν ενταφιαστεί. Το οστεολογικό υλικό προέρχεται από τις αρχαιολογικές ανασκαφές της ΑΤΤΙΚΟ ΜΕΤΡΟ στην πόλη της Θεσσαλονίκης και χρονολογείται στην Ρωμαϊκή εποχή (1ος-4ος αι. μ.Χ.). Για την επίτευξη του σκοπού εφαρμόστηκαν οι μεταβλητές δύο προηγούμενων μεθόδων : α) του Kerley (1965) και β) των Singh & Gunberg (1970). Στη συνέχεια, δημιουργήθηκαν ειδικές εξισώσεις παλινδρόμησης για την εφαρμογή στο Ελληνικό δείγμα. Ως υλικό αναφοράς, για την δημιουργία των εξισώσεων, χρησιμοποιήθηκαν δείγματα σύγχρονων ατόμων (8), γνωστού φύλου και ηλικίας από την Οστεολογική Συλλογή του Τμήματος Βιολογίας του Πανεπιστημίου Αθηνών. Η ηλικία που προέκυψε από της ιστολογικές μεθόδους συγκρίθηκε με την ηλικία που προέκυψε από την μακροσκοπική μελέτη προσδιορισμού της ηλικίας. Για την προετοιμασία των ιστολογικών δειγμάτων αναπτύχθηκαν δύο πρωτόκολλα: α) για οστά καύσεων και σύγχρονων και β) για οστά ενταφιασμών. Παράλληλα, για να μελετηθεί η επίδραση των υψηλών θερμοκρασιών στη μικροδομή των οστών, πραγματοποιήθηκε πειραματική πυρά σε κάτω άκρα σύγχρονων χοίρων και λήφθηκαν δείγματα, τα οποία εξετάστηκαν μικροσκοπικά.
description: The aim of the present study was to check the reliability and accuracy of histological methods for estimating age-at-death in skeletal material of archaeological context derived from burials and cremation. Specifically, we studied eight cremated individuals and 39 unburned individuals. The osteological material comes from the archeological excavations of the ATTIKO METRO in the city of Thessaloniki and dates back to Roman times (1st-4th century AD). To achieve this, the variables of two previous methods were used: a) Kerley (1965) and b) Singh & Gunberg (1970). Then, regression equations were created for the Greek sample. As a reference sample, for the creation of the equations, samples of modern individuals (n = 8), of known gender and age from the Osteological Collection of the Department of Biology of the University of Athens were used. The histological estimated age was compared with the macroscopical estimated age. Two protocols were developed for the preparation of histological samples: a) for cremation and modern bones and b) for burial bones. At the same time, in order to study the effect of high temperatures on the bone microstructure, an experimental cremation was performed on the lower limps of modern pigs and were sampled, in order to be examined microscopically.

description: Due to globalisation of trade and the growth of diverse, competitive and volatile markets, companies have for many decades developed and adapted, expanding their structures into a complex web of operations with varied roles, purposes and management needs. There is no single ‘type’ of corporation, nor any ‘one size fits all’ list of what each individual organisation will require during its cyclical life. Company law frameworks have therefore sought to accommodate multifarious demands for the fostering of a vibrant commercial domestic, regional and international market environment. Restructuring imperatives may be a result of expansion or potential demise occasioned by financial strain or other economic challenges and the need for rescue to preserve the value of business organisations to domestic economies. Complex, ‘single purpose’ restructuring processes have traditionally dealt with mergers, acquisitions, takeovers and, more recently, insolvency. In the case of financial distress, most developed jurisdictions adopted a ‘scheme of arrangement’ procedure to facilitate renegotiation, refinancing and rescue, as well as a proposal to reorganise liabilities and indeed effect organisational restructure. Schemes of arrangement has proven to be more flexible and has been adapted to manage institutional change. This has been particularly valuable in the rationalisation of complex multinational conglomerates, facilitating continued expansion, be it generically or by takeover. This study examines the framework and use of schemes of arrangement as an effective mechanism for companies of all sizes and formations to restructure their liabilities and operations in diverse national jurisdictions, with particular focus on the UK and the KSA. The other processes may continue to have their uses, but the scheme provides a relatively simple structure in the face of significant complexity. It is monitored by the courts with only limited intervention in what are essentially business decisions of the management supported by the special majority of those affected. Indeed, the relatively ubiquitous use of schemes of arrangement as a corporate legal service has proven to be an attraction for corporations seeking the jurisdiction most amenable to their plans ‘forum shopping’. It is thus a valuable marketing tool for economies in attracting company operations to the provider country. To achieve this, the KSA, a major focus of this study, has made substantial changes to the basis of its economy and reformed its bankruptcy law to facilitate corporate needs by the introduction of a scheme of arrangement framework accommodating Shari’a principles for a global market awash with opportunity as well as risk.
Calculation of Residual Oil Saturation for Surfactant Flood Eor Process From Injection Well Pressure Data

description: The objective of this thesis is to study the application of pressure transients from an injection well to determine residual oil saturation in a reservoir for a surfactant EOR process. A published analytical solution for the multiple-region moving boundary problem of water injection in a homogeneous reservoir with radial flow geometry was studied and the model was scripted using Excel VBA. The logarithmic derivative from the late time transient response from the injection well was found to depend on the properties of the water flooded zone near the well bore. From this constant derivative value, the fluid mobility in the flushed zone can be calculated. The fluid mobility can then be further used to calculate the reservoir permeability using appropriate relative permeability curves. Water injection in a homogenous reservoir under radial flow conditions was simulated using CMG’s black oil simulator. Several cases were run to account for varying reservoir conditions and it was found that the reservoir permeability could be calculated from the pressure data using suitable relative permeability functions. The observation that the late time derivative response from injection pressure data indicates the fluid mobility near the well bore behind the fluid front was used to calculate residual oil saturation for a surfactant EOR process. The logarithmic derivative was found to become constant at late time and was a function of injection rate, fluid viscosity, reservoir thickness, reservoir absolute permeability and relative permeability functions. If the reservoir absolute permeability and other fluid data are known, relative permeability of the injected fluid at residual oil saturation can be calculated which can be further used to evaluate residual oil saturation using appropriate relative permeability functions. Numerical simulations were made in CMG’s chemical simulator under varying reservoir conditions. It was found that relative permeability to water in the flushed zone can be calculated using the pressure response from an injection well and subsequently converted to reasonable estimates of residual oil saturation using the trapping number dependent relative permeability model.

description: The lack of geological information to appropriately reproduce the flow paths in typical reservoir modeling scenarios is one of the most significant sources of uncertainty and, consequently, it has been repeatedly addressed in multiple geological modeling approaches. However, current modeling techniques that combine geological and dynamic information are computationally extensive and frequently lead to geologically inconsistent models. Practitioners and particularly geologists have found the traditional geostatistics, based on the variogram and kriging, suitable to describe geological heterogeneity within a single facies, but too limiting for describing more organized geological features such as channels, fractures, and facies distributions among others. These geological features usually have the largest impact on the flow response, calling for a different approach using multiple-point statistics instead of variogram models to capture the required conditional information to generate more accurate models that exhibit more structural organization. Honoring the geological model is an important objective during the generation of static geological models; however, it is commonly forgotten during the integration of dynamic information. Reconciliation between the model predictions and the field records represents a rather significant challenge, considering the highly non-linear relationship between the model parameters and the production response. Reproduction of the geological heterogeneity during the calibration of the model response with the production history is the motivation behind the selection of a probabilistic approach for dynamic data integration. This work focuses on a probabilistic approach to integrate dynamic data that ensures consistency between reservoir models developed from one stage to the next. The algorithm relies on efficient parameterization of the dynamic data integration problem and permits rapid assessment of the updated reservoir model at each stage. This report is presented as part of the requirements to obtain a Master of Science degree in petroleum engineering under the Fast Track Option. It summarizes the proposal and preliminary results related with the Ph.D. dissertation that is currently on going.

Ο στόχος της εργασίας είναι διπλός: αφενός να εντοπιστούν οι πιθανές αιτίες που οδηγούν σε τέτοιες φαρμακευτικές αστοχίες στην Ελλάδα (κοινωνιολογικά αίτια, τακτικές προώθησης στο παραφαρμακευτικό μάρκετινγκ κλπ) και αφετέρου να εξετάσει ποιες είναι οι συνηθέστερες φαρμακευτικές αστοχίες που εντοπίζονται στην Ελλάδα. Ο εντοπισμός της συχνότητας τέτοιων φαινομένων και πιο συγκεκριμένα των ουσιών που αλληλεπιδρούν μεταξύ ενός φαρμακευτικού και ενός παραφαρμακευτικού προϊόντος οδηγώντας σε δυνητικά ανεπιθύμητες παρενέργειες, θα αποτελέσει ένα μελλοντικό οδηγό για διαμόρφωση αυστηρότερου ιατρικού και νομοθετικού πλαισίου σε σχέση με τη διακίνηση παραφαρμακευτικών ουσιών στην Ελλάδα.
description: The purpose of this paper is to identify and evaluate failures related to the reception of non-pharmaceutical products that are distributed through a pharmacy. The aim of the work is twofold: on the one hand to identify the possible causes that lead to such pharmaceutical failures in Greece (sociological causes, promotion tactics in parapharmaceutical marketing, etc.) and on the other hand to examine what are the most common pharmaceutical failures found in Greece. Identifying the frequency of such phenomena and more specifically the substances that interact between a pharmaceutical and a parapharmaceutical product leading to potentially adverse side effects, will be a future guide for shaping a stricter medical and legislative framework in relation to drug trafficking in Greece.

description: The paper explores the possibility of development a microwave technology for obtaining water extracts from berry press residues (wild bilberries and cranberries as the objects) and jelly products based on them, which will allow using the waste of freshly squeezed juices in business, such as restaurants and catering services. The antioxidant activity (DPPH and FRAP methods), content of phenolic compounds, flavonoids, anthocyanins, ascorbic acid were determined in berries and in berry press residues. The antioxidant activity of bilberry press residues was due to anthocyanins, and the activity of cranberry press residues was due to flavonoids. Using the microwave oven (magnetron power 800 W, frequency 2,450 MHz), water extracts were obtained in the ratio: for cranberries 1.5:10, for bilberries 1:10. The antioxidant activity of extracts depended on the type of berries and was greater in extracts from bilberry press residues. Extracts of bilberries and cranberries and their compositions (sugar-free and sugaradded) with gelatin as a gelling agent were used to produce the jelly products. Combining bilberry and cranberry extracts (70:30) with gelatin makes it possible to obtain jelly products without sugar. Heating of the ready recipe mixture after preliminary swelling of gelatin and without swelling of gelatin was carried out in the microwave oven. The antioxidant activity of jelly products was higher when using bilberry extracts than cranberries. An increase in the antioxidant activity of the extracts led to a slowdown in structure formation, but increased the plasticity of the products.

description: Botrytis cinerea is a causal agent of grey mould that damages many species of plants including Japanese quince (Chaenomeles japonica (Thumb.) Lindley ex Spach). Grey mould has been found on Chaenomeles spp. flowers, fruits in all stages as well as on twigs. Morphological variability within Botrytis species has been previously reported in the literature, but no information is available about B. cinerea isolated from Chaenomeles spp. The aim of this study was to describe the symptoms of grey mould and clarify the morphological variability of B. cinerea isolates obtained from samples collected in commercial plantations of Japanese quince. Samples of plant parts with different fungal disease symptoms were collected in eight commercial plantations of Japanese quince during vegetation seasons of 2017 and 2018. Some samples were taken in Japanese quince plantations in Lithuania and Estonia. A total of 286 isolates of fungi were isolated from damaged shoots, leaves and fruits of Japanese quince plants, using potato dextrose agar. Botrytis cinerea isolates (39) were separated depending on the morphological characteristics and were proved by using methods of molecular biology. B. cinerea was isolated from shoots, leaves and fruits. The isolates of B. cinerea were described and classified into distinct morphological types depending on the characteristics of mycelia, sclerotia, reverse side of media and the presence or absence of sporulation.

description: Le sentiment d’auto-efficacité se traduit par les croyances qu’un individu a sur ses propres capacités à réaliser une tâche spécifique et obtenir les effets attendus. La performance obtenue n’est pas uniquement le résultat de notre niveau de compétences puisque celui-ci est influencé par les jugements que nous portons sur nos habiletés. Selon Bandura (2007), ces jugements se construisent par l’entremise de quatre sources principales : l’expérience active de maîtrise, l’expérience vicariante, la persuasion verbale et l’état physiologique. Le projet à la base de ce mémoire vise une prise de conscience quant à nos pratiques langagières au sein d’une classe. Dans cette intention, nous nous intéressons de plus près à la troisième source, la persuasion verbale qui s’exprime lorsqu’un individu tente d’exercer une influence sur les perceptions que le récepteur a de ses propres compétences. Nous cherchons donc à étudier la possibilité d’un lien entre les feedbacks émis par l’enseignant et l’évolution positive ou négative du sentiment d’auto-efficacité des élèves. A partir de séquences enregistrées transcrites sous-forme de verbatim et de questionnaires portant sur le sentiment d’auto-efficacité et l’attribution causale, nous avons pu constituer un corpus de données que nous avons classées au moyen de tableaux et de grilles. Cette mise en évidence permet de dégager des tendances confirmant une relation entre les feedbacks évaluatifs formulés par l’enseignant et le sentiment d’auto-efficacité des élèves et de ce fait, l’importance des propos tenus par ce dernier à l’attention de sa classe.

description: Recently, we reported dioxygen binding and its activation by the Cr(II) compound [Cr(H2O)(LISQ)2] (1) [(LISQ)1− is o-iminothionebenzosemiquinonate(1–) π-radical]. In this work, we report the existence of ferromagnetism in its solid form. The plot of (χm)−1 versus T from 250 to 20 K reveals a Curie–Weiss constant of θ ~26 K suggesting a ferromagnetic coupling. A theoretical simulation on the susceptibility curve and the fitting of the χm versus T yielded g = 1.83 ± 0.002, J = 33.4 ± 0.001 cm−1, and θ = 25.2 ± 0.02 K with J >> D. Increase in EPR line width on cooling helped us calculate the Cr(II)–Cr(II) distance in the proposed dimer. Also we find that deprotonation of the aqua ligand in 1 is essential for dioxygen binding and its activation. Reaction with dioxygen is completely inhibited when there is no deprotonation. Reaction of 1 with dioxygen in pyridine (py) resulted in isolation of the O=Cr(IV) compound [O=Cr(LAP)2(py)] (2) [(LAP)1– is o-aminothiophenolate anion] and no monomeric O=Cr(V) has been detected by EPR. 1H NMR study of 1 in d6-DMSO with time shows increase in intensity of the –NH2 peak at 5.46 ppm, suggesting gradual reduction of the –NH groups in (LISQ)1– ligands.
