description: Ο νευρικός ιστός αποτελείται από νευρικά κύτταρα (νευρώνες) και νευρογλοιακά κύτταρα (νευρογλοία). Τα νευρογλοιακά κύτταρα παρεμβάλλονται μεταξύ των νευρώνων, εκτός από τις θέσεις των συνάψεων. Ενώ γνωρίζουμε αρκετά πράγματα για τους νευρώνες, ο ρόλος των νευρογλοιακών κυττάρων στις λειτουργίες του εγκεφάλου δεν έχει αναλυθεί επαρκώς. Ωστόσο, τις τελευταίες δεκαετίες, ερευνητικά δεδομένα καταδεικνύουν τον καθοριστικό ρόλο τους στις διεργασίες των μηχανισμών ανοσολογικής απόκρισης και κατ’ επέκταση την επίδραση σε νευρολογικές ασθένειες και στους μηχανισμούς συμπεριφοράς Στόχος της διπλωματικής αυτής εργασίας είναι: • Η περιγραφή της δομής και της λειτουργίας των νευρογλοιακών κυττάρων και η ανάδειξη του πρωταγωνιστικού ρόλου τους στο Κεντρικό Νευρικό Σύστημα (ΚΝΣ) • Η διερεύνηση του ρόλου των κυττάρων γλοίας στην συμπεριφορά.
description: Nerve tissue is made up of nerve cells (neurons) and glial cells (neuroglia). The glial cells are inserted between the neurons, except for the sites of synapses. While we know a lot about neurons, the role of glial cells in brain functions has not been adequately analyzed. However, in recent decades, research data demonstrate their crucial role in the processes of immune response mechanisms and consequently the impact on neurological diseases and behavioral mechanisms The aim of this dissertation is: • The description of the structure and function of the glial cells and the emergence of their leading role in the Central Nervous System (CNS) • The investigation of the role of glial cells in behavior.

description: The mixed-metal compounds CpM(CO)3(SnPh3) (1, M = Mo; 2, M = W) are obtained as the only isolable products from the reactions of [CpM(CO)3]2 with PhSSnPh3, whereas similar reactions with pymSSnPh3 (pymS = pyrimidine-2-thiolate) lead to the formation of chelate compounds CpM(CO)2(κ2-pymS) (3, M = Mo; 4, M = W). Separate experiments show that CpM(CO)3(SnPh3) are precursors of CpM(CO)2(κ2-pymS). CpM(CO)3(SnPh3) can also be synthesized in slightly improved yield from the direct reaction between [CpM(CO)3]2 and Ph3SnH, while the yield of CpM(CO)2(κ2-pymS) becomes negligible when [CpM(CO)3]2 is treated with pymSH.

description: A geochronological framework based on amino acid racemisation (AAR) and constrained by previously reported optically stimulated luminescence (OSL) ages is presented for the evolution and paleosea-level record of the Pleistocene Bridgewater Formation of the Mount Gambier region, of southern Australia. Within the study area, the Bridgewater Formation is represented by late early Pleistocene [Marine Isotope Stage (MIS) 23 at 933 ka] to Holocene barrier shoreline successions deposited during sea-level highstands. Regional monotonic uplift (0.13 mm yr–1) and pervasive calcrete development during the Pleistocene have preserved the sequence of calcarenite (mixed quartz-skeletal carbonate sand) shoreline complexes from denudation. AAR analyses confirm that the barriers generally increase in age landwards and correlate with sea-level highstands associated with interglacials as defined by the marine oxygen isotope record. AAR analyses on the benthic foraminifer Elphidium crispum have proved more reliable than the whole-rock method in extending the age range of AAR dating of these relict shoreline successions. Paleosea-levels from the coastal plain are as follows: MIS 7, –9 ± 2 m; MIS 9, 4 ± 1 m; and a minimum sea-level of 2 ± 2 m is derived for MIS 11. Paleosea-level could not be determined for MIS 15, 19 or 23 as diagnostic sea-level indicators were not identified within these sedimentary successions. Dismal Range, dated at 933 ± 145 ka (MIS 23), represents a correlative feature to the East Naracoorte Range but is some 25 km seaward of the Kanawinka Fault compared with the same barrier at Naracoorte. Mingbool Range (788 ± 18 ka) is of similar age to the West Naracoorte Range (MIS 19) and formed as an arcuate shoreline complex that became attached to the higher relief of the area represented by the Mount Burr Volcanic Province. The higher topographical relief resulted from crustal doming of the Oligo-Miocene Gambier Limestone caused by the intrusion of magma associated with the volcanic province. The AAR age of 788 ± 118 ka for Mingbool Range indicates that the Mount Burr volcanics predate the deposition of this shoreline complex.
Experimental Evaluation of Co-Solvents in Development of High Performance Alkali/Surfactant/Polymer Formulations for Enhanced Oil Recovery

Crude oil

description: The ability to select low-cost, high-performance surfactants for a wide range of crude oils under a wide range of reservoir conditions has improved dramatically. There are thousands of possible combinations of the chemicals (including salinities, hardness, oil concentrations) that could be tested for each oil, and each chemical combination requires many observations at reservoir temperature for proper evaluation, so it would take too long, cost too much and in many cases not even be feasible to test all combinations. The research presented in this work uses and describes a scientific understanding of how to match up the surfactant/co-surfactant/co-solvent characteristics with the oil characteristics, temperature, salinity and hardness. The work describes the role of co-solvents including some novel co-solvents in the formulation design and testing procedure. It is essential that the surfactant solution be a clear, stable aqueous phase. Surfactants that show ultra-low interfacial tension and excellent microemulsion phase behavior are often not sufficiently soluble at optimum salinity to give clear, stable aqueous solutions. Even slightly cloudy solutions often show phase separation or precipitation after a few days at reservoir temperature, which is very short compared to reservoir flooding times. The addition of polymer often makes the problem worse although the low solubility of the surfactant at high salinity is the fundamental problem. Surfactants with large hydrophobes produce the lowest IFT, but are often not sufficiently water soluble at optimum salinity. Hydrophilic co-surfactants and/or co-solvents are needed to make the solutions pass the stringent aqueous stability test. This research shows why this is so important, how to select and test the best co-solvents, and illustrates the results with core floods where the oil recovery was doubled by simply adding a small concentration of co-solvent to make the ASP slug clear. In such cases, the co-solvent more than pays for itself in terms of higher oil recovery because of the lower surfactant retention and improved effectiveness of the polymer for mobility control.

description: The aim of the present thesis was the study of marketing automations that can be used in social media in order to generate ideas for advertising campaigns. Firstly, the term automation is analyzed and after that follows a historical overview of marketing automations and the processes involved in creating this type of software. In the following chapter, customer management systems, so-called CRM systems, and how they interact with marketing automation platforms are analyzed. After that, a reference is made to the sales funnel and how automation works in the online sales process. The next chapter describes the data measurements that are being performed on social media and analyzes the Falcon.io application which is a tool for collecting data from social network accounts, and also some of its features. Next, the study talks about the Pandora application, which uses automations that generate ideas with the aim of creating advertising campaigns, which are personalized to the needs and wants expressed by the followers of a company on social media. Finally, a hypothetical example is given, in which Subway uses the Pandora application to discover its next future advertising campaign that meets the needs of its followers, and the conclusions of this study are being analyzed.

description: We measure threshold photoelectron spectra of the benzyl radical, which show transitions to at least three electronic states of the benzylium cation: 1A1, 3B2, and 1B2, with possible contributions from transitions to 3A1. The main features in the vibrationally resolved threshold photoelectron spectrum between 7.1 and 10.5 eV are assigned with the aid of Franck–Condon simulations to these four electronic states of benzylium. We measure the adiabatic ionisation energy of the benzyl radical to be 7.252(5) eV and observe a well-resolved vibrational progression in the lowest triplet state, 3B2, from which we obtain a measured singlet–triplet splitting of 1.928(7) eV in benzylium.

Sensitivity analysis

description: A crucial question that may be asked during exploratory reservoir analyses and data gathering is: "What is the relative significance of different reservoir parameters?" A parameter is significant if the knowledge of its exact value results in an appreciable reduction in the uncertainty of model estimates. Sensitivity Analysis (SA) quantifies and apportions the uncertainty in a model's estimates based on the uncertainty in the model's parameters. Thus, SA can be used to determine the relative significance of reservoir parameters. This report starts with the SA of four models using differential analysis, regression, correlation and variance-decomposition methods. The models are the bi-linear, polynomial, Stock Tank Oil Originally in Place, and Panda and Lake equations. These models demonstrate the relative merits of the SA methods. The report culminates in the development of a variance-based Monte Carlo (MC) tank model that is useful in the SA of reservoir production rate, pressure and recovery forecasts. The model assumes the reservoir is homogeneous and undersaturated, and that the reservoir is produced by primary depletion mechanisms. It provides a choice between Latin Hypercube and Sobol sampling. These sampling methods are more efficient than conventional MC or random sampling. In the cases considered, the sensitivity effects of different reservoir parameters vary over the producing period. Parameters with negligible main effects can have significant joint effects.

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 vs T from 250-20 K reveals a Curie-Weiss constant of θ ~26 K suggesting a ferrromagnetic coupling. A theoretical simulation on the susceptibility curve and the fitting of the χM vs 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.

description: This report presents a literature review of the impact of injection water quality on well injectivity and reservoir performance, making a focus on conceptual ideas, the expected impact on field operations, and some simple results of predictive models. The general reservoir, development and operational characteristics of the Guando field and its water injection project are related. The analysis of wells injectivities was split in several parts: A first part focuses on injectivity characteristics of each reservoir unit; the second part is based on the behavior of wells in terms of injection parameters and the final part shows a comparison against water quality and operational parameters. In each of the sections different aspects of the field data are analyzed.

description: Honey is a natural product, which is appreciated for its sweetness, high nutritional value and health benefits all over the world. Despite all benefits, the usage of honey in food industry is limited due to its high viscosity. The use of dried honey could be an alternative to liquid honey, and would allow to use it as an additive in a range of many different food products such as sauces, beverages, yogurts etc. There are many parameters, which are used to determinate the quality of honey. α-amylase (diastase) activity is one of the most important criteria to determine the quality and freshness of honey. The aim of the present study was to investigate and compare α-amylase activity in liquid honey samples and freeze-dried honey samples. Overall, 18 honey samples were dehydrated using a freeze-drying method. Freeze-drying of the samples was carried out at – 50.6 °C and the pressure was 0.036 mbar for 72 hours. α-amylase activity in the honey samples was tested using Amylazyme test tablets. The obtained results showed variability in α-amylase activity after the freeze-drying process. As hydroxymethylfurfural (HMF) is another important quality parameter of honey, the content of HMF was determined in the samples by high performance liquid chromatography. In some samples the concentration of HMF after freezedrying increased and was higher than it is allowed according to the International Honey Commission (for example, 55.75 mg kg-1 ).

description: Farmers operate in a turbulent environment that includes international competition, weather conditions and animal behaviour, for example, and is difficult for them to control. However, economy and productivity always have a high priority. As a consequence, farms have started to implement lean-inspired work systems. At the same time, health and safety are of urgent concern in the sector. This article explores how famers apply lean-inspired work processes. It identifies work environment changes during and after a lean implementation, as well as possible developments in the work environment following implementation of the lean philosophy. Data were collected from three groups: lean, lean-light and development-inclined reference farms (in total 54 farms), using a questionnaire and interviews. The results indicate that a majority of the lean farms were applying several lean principles and tools, and the lean philosophy. The leanlight farms applied parts of the lean concept, while the reference farms applied some of the more general tools, used in lean and elsewhere, such as visualisation in various forms and to various extents. The results showed positive effects of lean on the psychosocial work environment, better work structure and improved information, communication and co-operation. The physical work environment was improved to some extent by lean, where advantages such as a more structured and practical work environment with less physical movements and locomotion could be noticed. The lean concept provided a more structured and systematic approach to dealing with work and production environmental issues, for managers as well as for employees.

Hate

description: The constant expansion and creation of online social platforms attracts people of different nationalities, religions, sexual orientations, and social backgrounds. Society’s lack of respect for and understanding of those differences perpetuates negativity, general dissatisfaction, and eventually hate speech. Social media companies are using automated hate speech detection systems to limit the appearance of such abusive content. These systems, however, rely heavily on the volume and quality of data. Despite the fact that a large amount of public datasets for hate speech detection is available, they are limited to popular languages such as English, French, and Spanish, among others. In our approach, we aim at accurately identifying hateful content on unpopular languages with the help of pre-trained transformer models. Both monolingual and multilingual models are deployed, for this task. We mostly seek to learn whether training multilingual models in linguistically related languages can provide enhanced results compared to language-specific pre-trained monolingual models. Additionally, we examine the contribution of multiple languages to the fine-tuning process. From all the experiments performed, it is observed that multilinguality does indeed improve performance in a few cases.
description: Η συνεχής επέκταση και δημιουργία διαδικτυακών πλατφορμών κοινωνικής δικτύωσης, προσελκύει άτομα διαφορετικών εθνικοτήτων, θρησκειών, σεξουαλικού προσανατολισμού και κοινωνικής θέσης. Η έλλειψη σεβασμού και κατανόησης αυτών των διαφορών από την κοινωνία, ενισχύουν την αρνητικότητα, τη γενική δυσαρέσκεια και τελικά τη ρητορική μίσους. Οι εταιρείες μέσων κοινωνικής δικτύωσης χρησιμοποιούν αυτοματοποιημένα συστήματα ανίχνευσης ρητορικής μίσους για τον περιορισμό της εμφάνισης τέτοιου υβριστικού περιεχομένου. Τα συστήματα αυτά, ωστόσο, βασίζονται σε μεγάλο βαθμό στον όγκο και την ποιότητα των δεδομένων με τα οποία εκπαιδεύονται. Παρά το γεγονός ότι διατίθεται μεγάλος αριθμός δημόσιων συνόλων δεδομένων για ανίχνευση ρητορικής μίσους, τα σύνολα αυτά περιορίζονται σε δημοφιλείς γλώσσες όπως αγγλικά, γαλλικά και ισπανικά, μεταξύ άλλων. Στην προσέγγισή μας, στοχεύουμε στον ακριβή εντοπισμό περιεχομένου μίσους σε μη διάσημες γλώσσες με τη βοήθεια προεκπαιδευμένων μοντέλων μετασχηματισμού (Transformer Models). Τόσο μονογλωσσικά, όσο και πολυγλωσσικά μοντέλα έχουν χρησιμοποιηθεί γι’αυτό το σκοπό. Κυρίως επιδιώκουμε να εξερευνήσουμε εάν η εκπαίδευση πολυγλωσσικών μοντέλων, με γλωσσολογικά παρόμοιες γλώσσες, μπορεί να προσφέρει καλύτερα αποτελέσματα σε σχέση με την εκπαίδευση μονογλωσσικών μοντέλων. Επιπλέον, εξετάζουμε τη συμβολή πολλών γλωσσών στη διαδικασία εκπαίδευσης. Από όλα τα πειράματα που πραγματοποιήθηκαν, παρατηρείται ότι η πολυγλωσσία όντως βελτιώνει την απόδοση σε λίγες περιπτώσεις

description: The Australian continental margin presents highly contrasted settings depending on (1) the presence or absence of a fluvial sediment supply, (2) the distance from the Australian mainland, and (3) the local hydrological setting. Despite the importance in surface area of the continental margin around the Australian mainland, so far only a few studies have dealt with sedimentation, most of them focusing on the northeastern Australian Shelf. This work presents the first large-scale investigation of modern sedimentation along the southern margin of Australia in the SE Indian Ocean, and the western margin of the Tasman Sea. Sedimentation intensity was assessed on a century timescale using a multi-tracer approach (234Th, 210Pb, 232Th) on interface cores around the 1000 m water depth contour. 234Th (half-life: 24.1 days) in excess was detected in all surface samples, testifying to the occurrence of freshly deposited particles. Sedimentation and mass accumulation rates based on sedimentary 210Pb excess profiles (CF:CS model) range between 0.027 and 0.280 cm y–1 and between 14 and 222 mg cm–2 y–1, respectively. Whereas sedimentation rates are low and associated with carbonates on the western margin, sediments are more influenced by the detrital fraction and organic carbon on the eastern side of the continent. In comparison with northern continental margins (e.g. Timor Sea, Gulf of Papua), the southern Australian margin receives little sediment today, as it is rarely linked to a river system that would otherwise deliver large amounts of sediment, and also because of the presence of the extended shelf south of Australia.

description: Η παρούσα μελέτη ερευνά τα ζητήματα αδικοπρακτικής ευθύνης που ανακύπτουν σε περίπτωση ζημιογόνας λειτουργίας των λεγόμενων αυτόνομων συστημάτων (αλλιώς και: συστημάτων τεχνητής νοημοσύνης). Ελλείψει δε συναφούς ειδικής νομοθετικής ρύθμισης, επιχειρείται να αναδειχθεί η προσήκουσα νομική βάση ευθύνης μεταξύ των φαινόμενων ως συναφών με την επίλυση του προβλήματος, όπως η γενική αδικοπρακτική ευθύνη των ΑΚ 914 επ., η ευθύνη του παραγωγού ελαττωματικών προϊόντων, τόσο η γενικά ρυθμισμένη (ΑΚ 914 συνδ. 925) όσο και η ειδικά ρυθμισμένη (άρθρ. 6 και 7 ν. 2251/1994), και η ειδική αστική ευθύνη από τη λειτουργία των αυτοκινήτων (Ν. ΓπΝ’/4.12.1911) «περί της εκ των αυτοκινήτων ποινικής και αστικής ευθύνης».
description: The present thesis aims for an analysis of the issues of tort liability that arise in the case of harmful operation of autonomous systems (or artificial intelligence systems). In the absence of relevant specific legislation, an attempt is made to highlight the appropriate legal basis of liability among the phenomena related to the solution of the problem, such as the general tort liability of AK 914 et seq., the liability of the producer of defective products, the generally regulated ( art. 914 comb. 925 of the Greek Civil Code) as well as the specially regulated (art. 6 and 7 of the No. 2251/1994 law), and the special civil liability from the operation of the cars (No. ΓπΝ'/4.12.1911 law) “on the criminal and civil liability ”.

description: Η Ρολάνδειος επιληψία αποτελεί την πιο κοινή μορφή επιληψίας σε παιδία ηλικίας 6-8 ετών. Σκοπός της μελέτης αυτής ήταν η συσχέτιση του μονονουκλεοτιδικού πολυμορφισμού rs10868235 του γονιδίου NTRK2, το οποίο ανήκει στην οικογένεια των νευροτροφινών, με την Ρολάνδειο επιληψία σε παιδιά από την Ελλάδα. Σύγχρονες μελέτες συσχετίζουν την εμφάνιση επιληπτικών συνδρόμων με μεταλλάξεις στην οικογένεια των νευροτροφινών. Στην παρούσα μελέτη πήραν μέρος 39 ασθενείς με Ρολάνδειο επιληψία, οι οποίοι αποτέλεσαν την ομάδα μελέτης και 38 υγιείς, οι οποίοι αποτέλεσαν την ομάδα ελέγχου. Αυτές οι δύο ομάδες συγκρίθηκαν για την κατανομή των γονοτύπων και αλληλομόρφων του πολυμορφισμού rs10868235. Τα αποτελέσματα της στατιστικής ανάλυσης έδειξαν οι κατανομές των γονοτυπικών συχνοτήτων τείνουν να παρουσιάσουν μια στατιστικά σημαντική διαφορά (p=0.0542) παρόλα αυτά όμως δεν αποτελεί έγκυρο δεδομένο λόγω του μικρού δείγματος που αναλύθηκε στην παρούσα μελέτη. Επιπλέον, η σύγκριση μεταξύ των αλληλομόρφων δεν κατέδειξε κάποια συσχέτιση (p=0.692). Συμπερασματικά αξίζει να σημειωθεί ότι είναι αναγκαίο να διεξαχθούν ανάλογες μελέτες στον ελληνικό πληθυσμό, όπου οι ομάδες μελέτης θα περιλαμβάνουν μεγαλύτερο δείγμα πληθυσμού. Επιπλέον τόσο νέες μελέτες και σε άλλους πολυμορφισμούς του γονιδίου NTRK2 όσο και σε άλλα γονίδια θα συμβάλλουν σημαντικά στην κατανόηση της παθογένεσης της Ρολάνδειου επιληψίας.
description: Rolandic epilepsy is the most common form of epilepsy in 6-8 year old children. The purpose of this study was to determine the correlation of the single nucleotide polymorphism (SNP) rs10868235 of NTRK2, which belongs to the Neurotrophic family of proteins, with Rolandic epilepsy in Greek children. Recent studies have associated the emergency of epilepsy syndromes with mutations to the family of Neurotrophins. In this study, 39 patients with Rolandic epilepsy were included to form the patient group, and 38 healthy individuals consisted the control group. The prevalence of the rs10868235 SNP was compared between the two groups. Statistical analysis showed that the distribution of rs10868235 genotypes was marginally statistical significant (p=0.0542), yet the small sample groups included in the present study does not allow for a decisive conclusion. Comparison of rs10868235 alleles distribution between the two groups did not reveal any correlation (p=0.692). These results highlight the need to include bigger study groups. Also, further investigation of other polymorphisms of NTRK2 and other genes, will undoubtedly aid in understanding the pathogenesis of Rolandic epilepsy.

description: Αντικείμενο της παρούσας εργασίας είναι η διενέργεια μιας εις βάθος ανασκόπησης του προβλήματος του περιοδεύοντος πωλητή με έμφαση στις τεχνικές επίλυσης οι οποίες στηρίζονται στην βαθιά ενισχυτική μάθηση, όπως αυτές διατυπώνονται στην υπάρχουσα βιβλιογραφία. Η βαθιά ενισχυτική μάθηση έχει χρησιμοποιηθεί επιτυχώς για την διαχείριση ακολουθιών από δεδομένα, την δημιουργία αναπαραστάσεων ακολουθιών και γράφων και την επίλυση προβλημάτων συνδυαστικής βελτιστοποίησης. Οι μέθοδοι οι οποίες παρουσιάζονται δίνουν λύσεις σε πολλά από τα ζητήματα που σχετίζονται με την επίλυση του προβλήματος του περιοδεύοντος πωλητή, όπως οι διαστάσεις των ακολουθιών δεδομένων, η συνθετότητα των πολιτικών και η αυτοματοποίηση της διαδικασίας λύσης. Γίνεται αναλυτική περιγραφή των λύσεων που έχουν προταθεί, συμπεριλαμβανομένων της αρχιτεκτονικής των μοντέλων, της μαθηματικής διατύπωσης της πολιτικής και της διαδικασίας εκπαίδευσης και βελτιστοποίησης των περιβάλλοντων μάθησης.
description: The object of this thesis is an in-depth review of the travelling salesman problem with emphasis given on the solutions based on deep reinforcement learning, as they are presented in the existing bibliography. Deep reinforcement learning has been successfully used to deal with sequences of data, the creation of embeddings of the information of sequences and graphs and the solution of combinatorial optimization problems. The methods which are presented tackle several of the issues related with the travelling salesman problem such as the size of the sequences of data, the complexity of policies and the automation of the solution process. Detailed analysis is given of the solutions that have been proposed, including the architecture of the models, the policy formalization and the training and optimization of the learning environments.

description: Σκοπός της διατριβής ήταν η μελέτη του νοήματος της επιθυμίας. Εξετάσαμε τους ορισμούς και την ιστορία της και στη συνέχεια παρουσιάσαμε αναλυτικά όχι μόνο την άποψη του Πλάτωνα, του Νίτσε και της σύγχρονης ψυχολογίας αλλά και την θεωρία μας για το δράμα του νοήματός της. Μιλήσαμε για τους κινδύνους και τα εμπόδια, τα οποία προσπαθήσαμε και να ξεπεράσουμε, για να αναδείξουμε μια νέα τάση της επιθυμίας, την δράση μέσα από το δράμα. Προσπαθήσαμε να την απαλλάξουμε από τις χρόνιες κατηγορίες και τέλος να την αποδεχτούμε ως αυτή έχει, ως επιθυμία, ως αυτή που δίχως φόβο, ελπίζει, λαχταρά, νοσταλγεί, αγωνία και αγωνίζεται για μια στιγμή, την οποία ονομάσαμε Θεία.
description: The aim of the present thesis was to study the meaning of desire. We examined definitions and the history behind desire and then we presented, in detail, not only the view of Plato, Nietzsche and the modern psychological point, but also (we presented) our theory of its dramatical meaning. We talked about the dangers and obstacles, which we tried to overcome, to highlight a new trend of desire, the action through drama. We tried to free every desire from the chronic accusations and finally to accept it, as it is, as a desire, as one, who without fear, hopes, longs for, sighs for, lives the agony and fights for a moment, which we called Divine.

description: Η διδασκαλία είναι η βάση κάθε εκπαιδευτικής διαδικασίας και αυτό ενισχύεται στην περίπτωση της Πρωτοβάθμιας και Δευτεροβάθμιας Εκπαίδευσης. Κυρίαρχο ρόλο στην απόδοση της μάθησης διαδραματίζουν τόσο οι ακαδημαϊκές δεξιότητες του διδάσκοντα, όσο και η γνώση του ίδιου του αντικειμένου μάθησης. Από το 2019, η διαδικασία επιλογής εκπαιδευτικών πραγματοποιείται μέσω ενός συστήματος ιεράρχησης ακαδημαϊκών προσόντων. Με αφορμή αυτήν τη διαδικασία, η παρούσα εργασία στοχεύει στην κάλυψη του ερευνητικού κενού αναφορικά με τον θεσμό των αναπληρωτών στην Πρωτοβάθμια και Δευτεροβάθμια Εκπαίδευση, με γνώμονα την ακαδημαϊκή τους ταυτότητα. Αναλύονται σε βάθος τα προσόντα των υποψήφιων εκπαιδευτικών με χρήση στατιστικών μεθόδων, αλλά και με τη συνδρομή της Θεωρίας Γράφων. Τέλος, τα διαγράμματα, οι πίνακες και τα γραφήματα που παρουσιάζονται αποκωδικοποιούν το μορφωτικό επίπεδο και επιτρέπουν τη σύγκριση των διαφόρων εκπαιδευτικών ειδικοτήτων.
description: Teaching provides the power of education, even more so in Primary and Secondary schools. Academic skills and deeper knowledge of the subject partially determine the quality of teaching. Since 2019, the access in teaching positions is controlled by an hierarchical award system in which qualifications like Master or PhD degree are being considered. Driven by that opportunity, this thesis assesses teachers' academic qualifications in Primary and Secondary Education faculties. In this direction, statistical analysis and graph theory tools were mainly used and hence, the scientifically proven inferences which are presented derive from the respective graphs and charts.

description: Leptin is an adipokine that acts in the central nervous system and regulates energy balance. Animal models and human observational studies have suggested that leptin surge in the perinatal period has a critical role in programming long-term risk of obesity. In utero exposure to maternal hyperglycemia has been associated with increased risk of obesity later in life. Epigenetic mechanisms are suspected to be involved in fetal programming of long term metabolic diseases. We investigated whether DNA methylation levels near LEP locus mediate the relation between maternal glycemia and neonatal leptin levels using the 2-step epigenetic Mendelian randomization approach. We used data and samples from up to 485 mother-child dyads from Gen3G, a large prospective population-based cohort. First, we built a genetic risk score to capture maternal glycemia based on 10 known glycemic genetic variants (GRS10) and showed it was an adequate instrumental variable (β = 0.046 mmol/L of maternal fasting glucose per additional risk allele; SE = 0.007; P = 7.8 × 10−11; N = 467). A higher GRS10 was associated with lower methylation levels at cg12083122 located near LEP (β = −0.072 unit per additional risk allele; SE = 0.04; P = 0.05; N = 166). Direction and effect size of association between the instrumental variable GRS10 and methylation at cg12083122 were consistent with the negative association we observed using measured maternal glycemia. Lower DNA methylation levels at cg12083122 were associated with higher cord blood leptin levels (β = −0.17 log of cord blood leptin per unit; SE = 0.07; P = 0.01; N = 170). Our study supports that maternal glycemia is part of causal pathways influencing offspring leptin epigenetic regulation.

description: Κατά τα τελευταία έτη, στο περιαστικό δάσος του Σέιχ Σου της Θεσσαλονίκης, εμφανίστηκε εκτεταμένη προσβολή ατόμων Pinus brutia Ten., από το φλοιοφάγο έντομο Tomicus piniperda L. Η προσβολή αυτή εξαπλώθηκε γρήγορα πιθανόν λόγω των δυσμενών εδαφικών συνθηκών που επικρατούν στο μεγαλύτερο μέρος του δάσους. Για την αντιμετώπιση της προσβολής πραγματοποιήθηκε υλοτομία των προσβεβλημένων ατόμων και απομάκρυνση των κορμών τους, αφήνοντας στην επιφάνεια του εδάφους μεγάλες ποσότητες φυτικών υπολειμμάτων. Για το σκοπό της έρευνας πραγματοποιήθηκε δειγματοληψία του δασικού τάπητα και του εδάφους. Τα αποτελέσματα της έρευνας έδειξαν ότι, στο δασικό τάπητα η συσσώρευση της οργανικής ουσίας και πολλών θρεπτικών στοιχείων, είναι πολύ μεγαλύτερη στις προσβεβλημένες και υλοτομημένες επιφάνειες σε σύγκριση με τις υγιείς. Λόγω της πρόσφατης υλοτομίας, η αποσύνθεση των φυτικών υπολειμμάτων δεν βρίσκεται σε αρκετά προχωρημένο στάδιο και επομένως, οι μεταβολές που εντοπίζονται στο δασικό τάπητα, δεν εμφανίζονται ακόμα στις αντίστοιχες μετρήσεις του εδάφους, πράγμα που αναμένεται να συμβεί με το πέρας της αποσύνθεσης.
description: In the past few years, in the suburban forest of Sheich Sou in Thessaloniki, there has been an extensive infestation of the species Pinus brutia, by bark-eating insect Tomicus piniperda L. The fast spreading of the infestation was due to the unfavorable soil conditions existing in the biggest part of the forest. In order to deal with the infestation, the infected trees were felled and their barks were removed, leaving on the ground large quantities of plant debris. For the purpose of the research, samples of the forest floor and soil were taken. The study’s results have shown that in the forest floor, the accumulation of organic matter and many nutrients, is way higher in the affected and felled areas, in comparison to the healthy ones. Due to the recent logging, however, the decomposition of the plant debris is not at an advanced stage and therefore, the significant differences found in the forest floor results, are not yet to be noticed in the respective soil measurements, which is expected to happen with the end of decomposition.
