description: In this paper we present a hybrid feedback approach to solve the navigation problem of a point mass in the n-dimensional space containing an arbitrary number of ellipsoidal shape obstacles. The proposed hybrid control algorithm guarantees both global asymptotic stabilization to a reference and avoidance of the obstacles. The intuitive idea of the proposed hybrid feedback is to switch between two modes of control: stabilization and avoidance. The geometric construction of the flow and jump sets of the proposed hybrid controller, exploiting hysteresis regions, guarantees Zeno-free switching between the stabilization and the avoidance modes. Simulation results illustrate the performance of the proposed hybrid control approach for 2-dimensional and 3-dimensional scenarios.

description: Η παρούσα εργασία πραγματεύεται μια αρχαία εφαρμοσμένη τέχνη ή χειροτεχνία, την κοσμηματοτεχνία, η οποία, εξαιτίας των μορφών που έχει στις μέρες μας, διεκδικεί μια θέση ανάμεσα στις εικαστικές τέχνες, καθώς οι δημιουργίες, ο διάλογος των καλλιτεχνών στο εν λόγω πεδίο και το πάθος που αυτοί επιδεικνύουν, επεναπροσδιορίζουν τη σχέση μας με το κόσμημα και την πολλαπλότητα της σημασίας του και των μορφών που περιλαμβλανει. Η εργασία αφορά κυρίως την επώνυμη, πρωτότυπη ελληνική παραγωγή του 20ου αιώνα. Κρίθηκε ωστόσο σκόπιμο να παρουσιαστεί, έστω και εν συντομία, ένα μέρος της διεθνούς παραγωγής προκειμένου αυτό να αποτελέσει ένα ευρύτερο πλαίσιο αναφοράς και πληρέστερης κατανόησης του υλικού. Η ελληνική κοσμηματοτεχνία προσεγγίζεται ιστορικά και παρουσιάζεται το έργο συγκεκριμένων δημιουργών : εικαστικών καλλιτεχνών, καλλιτεχνών-κοσμηματοποιών(studio) και "εμπορικών", δημιουργών, που έθεσαν την προσωπική τους σφραγίδα και συνετέλεσαν στην περαιτέρω εξέλιξη της τέχνης αυτής. Στόχος υπήρξε να παρουσιαστεί μια εκτενής εικόνα και να καλυφθεί ένα κενό της έρευνας, καθώς η μεγάλη διασπορά του υλικού, η δυσκολία εντοπισμού του, η έλλειψη αρχείων και φωτογραφικού υλικού επέβαλαν την κατά το δυνατόν εκτενέστερη συλλογή, διάσωση και ταξινόμησή του
description: This dissertation deals with jewellery, an ancient applied art of craft, that demands its place among the figurative arts, because of the forms it has recently acquired. The created works of art, the dialogue among the artists on this field and their passion redefine our relationship with the jewel and the multiplicity of its meaning and forms. The dissertation regards mainly the eponymous, original Greek production of the 20th century. It has benn considered important to present, even in brief, the international production, so as to offer a broader framework for further reference and better comprehension of the material studied. The Greek jewellery is historically approached. The pieces of work of specific creators, like figurative artists, studio and "commercial" jewelers is also presented. All of them have been creators with a strongly individual character, have left their imprint on the art of jewellery and contirbuted to its evolution. The main objective has been to present en extensive picture and to cover a gap in the research, as the great dispension of the material, the difficulties in its localization and the scarcity of relative archives and photographic material have imposed its best possible collection, preservation and classification

description: Background: Primary writing tremor is a task-specific phenomenon that has been described as variants of essential tremor or dystonia. Phenomenology Shown: We describe the case of a 63-year-old female who initially had primary writing tremor, later developed Parkinson’s disease, and once initiated on carbidopa/levodopa had improvement in her parkinsonism and her writing tremor. Educational Value: As neither essential tremor nor typical brachial dystonia respond to carbidopa/levodopa, our case documents that at least some cases of primary writing tremor are not variants of either dystonia or essential tremor.

description: Simple coarse-grained models, such as the Gaussian Network Model, have been shown to capture some of the features of equilibrium protein dynamics. We extend this model by using atomic contacts to define residue interactions and introducing more than one interaction parameter between residues. We use B-factors from 98 ultra-high resolution X-ray crystal structures to optimize the interaction parameters. The average correlation between GNM fluctuation predictions and the B-factors is 0.64 for the data set, consistent with a previous large-scale study. By separating residue interactions into covalent and noncovalent, we achieve an average correlation of 0.74, and addition of ligands and cofactors further improves the correlation to 0.75. However, further separating the noncovalent interactions into nonpolar, polar, and mixed yields no significant improvement. The addition of simple chemical information results in better prediction quality without increasing the size of the coarse-grained model.

description: Ablative Rayleigh-Taylor instability growth was investigated to elucidate the fundamental physics of thermal conduction suppression in a magnetic field. Experiments found that unstable modulation growth is faster in an external magnetic field. This result was reproduced by a magnetohydrodynamic simulation based on a Braginskii model of electron thermal transport. An external magnetic field reduces the electron thermal conduction across the magnetic field lines because the Larmor radius of the thermal electrons in the field is much shorter than the temperature scale length. Thermal conduction suppression leads to spatially nonuniform pressure and reduced thermal ablative stabilization, which in turn increases the growth of ablative Rayleigh-Taylor instability.

Publisher: name: UNSPECIFIED
Year: 2021

description: In dieser Arbeit wurden Dünnschicht Volloxid-Varaktoren bestehend aus einer SrMoO3/BaxSr1-xTiO3/Platin/Gold Heterostruktur untersucht. Die epitaktischen Varaktoren wurden auf dem hochleitfähigen Oxid SrMoO3 mit einer Schichtdicke von bis zu 5 µm und der funktionalen dielektrischen Schicht BaxSr1-xTiO3 mit gepulster Laserablation gefertigt. Die epitaktische volloxid Bauweise ermöglicht die Nutzung funktionaler Schichten mit einer Dicke von weniger als 100 nm und zeigt hohe Steuerbarkeiten bei geringen Lithiumionen-Batterie Spannungen von 3,7 V. Die elektrischen Eigenschaften der Varaktoren hängen von der funktionalen dielektrischen Schicht ab. Aus diesem Grund wurde die Kristallstruktur, die Kationenstöchiometrie und die Oxidation der epitaktischen BaxSr1-xTiO3 -Schichten untersucht. Die elektrischen Eigenschaften, Steuerbarkeit, Permittivität und die Mikrowellenverluste wurden als Bewertungsparameter für die Optimierung des Wachstums genutzt. Epitaktische BaxSr1-xTiO3-Schichten mit erhöhtem Sauerstoffgehalt wurden bei Substrattemperaturen von 470 °C durch Optimierung der Laserenergiedichte und des Sauerstoffpartialdrucks erreicht. Diese Varaktoren zeigten eine höhe relative dielektrische Permittivität von über 300 und eine hohe Steuerbarkeit von über 3. Der Effekt der Titanstöchiometrie auf die Performanz der BaxSr1-xTiO3-Schichten wurde ebenfalls untersucht. Die erreichte elektrische Performanz der Volloxid-Varaktoren übertrifft die Performanz von konventionellen Varaktoren mit Platin-Bodenelektroden und polykristalliner funktionaler Schicht, was sie zu einer Innovation für die Verwendung in Mobilfunkgeräten macht.

description: We consider the analogue of the 4th Appelrot class of motions of the Kowalevski top for the case of two constant force fields. The trajectories of this family fill the four-dimensional surface O^4 in the six-dimensional phase space. The constants of three first integrals in involution restricted to this surface fill one of the sheets of the bifurcation diagram in R^3. We point out the pair of partial integrals to obtain the explicit parametric equations of this sheet. The induced system on O^4 is shown to be Hamiltonian with two degrees of freedom having the thin set of points where the induced symplectic structure degenerates. The region of existence of motions in terms of the integral constants is found. We provide the separation of variables on O^4 and the algebraic formulae for the initial phase variables.

Visual attention in psychopathic criminals
Creators: name: Harpur, Timothy John
Publisher: name: University of British Columbia
Year: 2011

description: This study was designed to examine the hypothesis that criminal psychopaths differ from criminal nonpsychopaths in their ability to over-focus attention on certain kinds of stimuli. For the purposes of this study, the concept of over-focussing was operationalized to mean the ability to process stimuli more quickly or efficiently by making use of one or more attentional mechanisms for selecting among locations or stimuli. A second aim of the study was to identify the component processes contributing to this more efficient selection. Five experiments were run to assess several different components of attention contributing to selection of stimuli in a variety of paradigms. Experiments 1 and 2 assessed covert orienting of attention across the visual field using both peripherally presented physical cues and centrally presented symbolic cues to prime locations in visual space. Three dissociable components of attention were assessed in this paradigm. Experiments 3-5 were designed to assess the efficiency of processing a target item in the presence of a distractor item. Four additional dissociable components of selective attention were measured in these three studies. The results supported the hypothesis that psychopaths can over-focus attention, but the groups were differentiated by only one of the component processes measured. In Experiments 1 and 2 endogenous orienting of attention was greater for psychopaths than for nonpsychopaths. In these paradigms endogenous facilitation controlled the allocation of attention to cued locations, and the subsequent speeding of reaction time to targets presented at those locations, when the cue was symbolic or predictive, but not when it involved a physical change of energy at the cued location. This strategic allocation of attention probably resulted from the predictive validity (approximately 68% valid) of the cue in relation to the target. Other component processes failed to differentiate the groups. These included measures of exogenous orienting and inhibition of return in experiments 1 and 2, and measures of interference due to a distracting stimulus, habituation of interference, attenuation of interference due to spatial displacement of the distractor, and negative priming in experiments 3-5. The difference in covert orienting was replicated in experiments 1 and 2 in two groups of criminals who also failed to demonstrate any abnormalities in a variety of other processes involved in attention. It was concluded that psychopaths differ from nonpsychopaths specifically in their strategic allocation of attention in situations of moderate uncertainty, but show no other abnormalities in the component processes that control attention.
Management of Neuroacanthocytosis Syndromes

description: Background: The two core neuroacanthocytosis (NA) syndromes, chorea-acanthocytosis (ChAc) and McLeod syndrome, are progressive neurodegenerative disorders that primarily affect the basal ganglia. The characteristic phenotype comprises a variety of movement disorders including chorea, dystonia, and parkinsonism, as well as psychiatric and cognitive symptoms attributable to basal ganglia dysfunction. These disorders are symptomatically managed on a case-by-case basis, with very few practitioners seeing more than a single case in their careers. Methods: A literature search was performed on PubMed utilizing the terms neuroacanthocytosis, chorea-acanthocytosis, and McLeod syndrome, and articles were reviewed for mentions of therapies, successful or otherwise. Results: There have been no blinded, controlled trials and only one retrospective case series describing ChAc. The various therapies that have been used in patients with NA syndromes are summarized. Discussion: Management remains at present purely symptomatic, which is similar in principle to other more common basal ganglia neurodegenerative disorders such as Huntington’s disease (HD) and Parkinson’s disease (PD). However, there are some specific issues particular to NA syndromes that merit attention. An integrated multidisciplinary approach is the ideal management strategy for these complex and multifaceted neurodegenerative disorders.

description: Corrections of order $α^4$Ry are calculated for the singlet states $1^1S_0$ and $2^1S_0$ of the helium atom. The result for $1^1S_0$ state is in slight disagreement with that of Korobov and Yelkhovsky in [Phys. Rev. Lett. {\bf 87}, 193003 (2001)]. The results obtained lead to a significant improvement of transition frequencies between low lying levels of the helium atom. In particular theoretical predictions for the $2^1S_0 - 1^1S_0$ transition are found to be in disagreement with experimental values.

Impact of the Bounds on the Direct Search for Neutralino Dark Matter on Naturalness

description: In the Minimal Supersymmetric Extension of the Standard Model (MSSM) the higgsino mass parameter $μ$ appears both in the masses of the Higgs bosons and in the neutralino mass matrix. Electroweak finetuning therefore prefers small values of $|μ|$. On the other hand, bino--like neutralinos make a good dark matter candidate. We show that current direct search limits then impose a strong lower bound on $|μ|$, in particular for $μ> 0$ or if the masses of the heavy Higgs bosons of the MSSM are near their current limit from LHC searches. There is therefore some tension between finetuning and neutralino dark matter in the MSSM. We also provide simple analytical expressions which in most cases closely reproduce the numerical results.

description: Background: Holmes’ tremor is characterized by a combination of rest, postural, and kinetic tremor that is presumably caused by interruption of cerebello-thalamo-cortical and nigrostriatal pathways. Medical treatment remains unsatisfactory. Case Report: A 16-year-old girl presented with Holmes’ tremor caused by a transient midbrain abnormality on magnetic resonance imaging (MRI). To explore the discrepancy between persistent tremor and resolved MRI changes, we performed dopamine transporter single-photon emission computed tomography (DaT-SPECT) with a 123I-ioflupane that revealed nearly absent DaT binding in the right striatum. Levodopa dramatically improved the tremor. Discussion: This is only the second report of a transient midbrain MRI abnormality disrupting nigrostriatal pathways. The case highlights the sometimes limited sensitivity of morphologic imaging for identifying the functional consequences of tissue damage and confirms that DaT imaging may serve as a predictor for levodopa responsiveness in Holmes’ tremor.

description: Gerstmann–Sträussler–Scheinker (GSS) disease is an autosomal dominant neurodegenerative disease, and it is characterized by progressive cerebellar ataxia. Up to now, GSS cases with the p.P102L mutation have mainly been reported in Caucasian, but rarely in Asian populations. A 54-year-old female patient presented with an unstable gait in the hospital. Last year, she was unable to walk steadily and occasionally choked, could not even walk independently gradually. After taking her medical history, we found that she was misdiagnosed with schizophrenia before the gait problems. The patient’s father showed similar symptoms and was diagnosed with brain atrophy at the age of 56, but her daughter showed no similar symptoms at present. On arrival at the Neurology Department, the patient’s vital signs and laboratory examinations showed no abnormality. As the proband presented with cerebellar ataxia and had an obvious family history, we were sure that she had hereditary cerebellar ataxia. Then, patient’s brain MRI showed an abnormal signal in the right parietal cortex and bilateral small ischaemic lesions in the frontal lobe. A gene panel (including 142 ataxia-related genes) was performed, and a heterozygous mutation PRNP Exon2 c.305C>T p. (Pro102Leu) was identified. Her daughter had the same heterozygous mutation. The patient was diagnosed with GSS with mental disorders as initial symptoms. After 2 months of TCM treatment, the patient’s walking instability decreased, and her emotional fluctuations were less than before. In conclusion, we have reported a rare case of GSS in Sichuan, China, and the family with mental disorder as the first symptom was finally confirmed with GSS PRNP P102L mutation.

description: We present Keck diffraction limited H-band photometry of a z~1.3 Type Ia supernova (SN) candidate, first identified in a Hubble Space Telescope (HST) search for SNe in massive high redshift galaxy clusters. The adaptive optics (AO) data were obtained with the Laser Guide Star facility during four observing runs from September to November 2005. In the analysis of data from the observing run nearest to maximum SN brightness, the SN was found to have a magnitude H=23.9 +/- 0.14 (Vega). We present the H-band (approximately rest-frame R) light curve and provide a detailed analysis of the AO photometric uncertainties. By constraining the aperture correction with a nearby (4" separation) star we achieve 0.14 magnitude photometric precision, despite the spatially varying AO PSF.

description: We predict the resonance enhanced magnetic field dependence of atom-dimer relaxation and three-body recombination rates in a $^{87}$Rb Bose-Einstein condensate (BEC) close to 1007 G. Our exact treatments of three-particle scattering explicitly include the dependence of the interactions on the atomic Zeeman levels. The Feshbach resonance distorts the entire diatomic energy spectrum causing interferences in both loss phenomena. Our two independent experiments confirm the predicted recombination loss over a range of rate constants that spans four orders of magnitude.

description: In the context of this dissertation, the geometry of a class of wideband dipole antennas is presented. Bandwidth enhancement is achieved by carefully designing the feeling network, as well as by using parasitic elements, Moreover, the methodology for implementing low-cost antennas is also presented, using parasitic elements. Moreover, the methodology for implementing low-cost antennas is also presented, using common glass as a substrate, for WLAN applications. This dissertation also deals with the problem of modelity the antenna radiation pattern, for use in propagation prediction tools. A novel reconstruction algorithm is proposed for estimating the 3D radiation solid of antennas. The new method significantly improves the approximation error, compared to other techniques found in literature. The proposed algorithm is also validated by a set of measurements prformed on antennas of a real DCS1800 base station

description: In disordered itinerant magnets with arbitrary symmetry of the order parameter, the conventional quantum critical point between the ordered phase and the paramagnetic Fermi-liquid (PMFL) is destroyed due to the formation of an intervening cluster glass (CG) phase. In this Letter we discuss the quantum critical behavior at the CG-PMFL transition for systems with continuous symmetry. We show that fluctuations due to quantum Griffiths anomalies induce a first-order transition from the PMFL at T=0, while at higher temperatures a conventional continuous transition is restored. This behavior is a generic consequence of enhanced non-Ohmic dissipation caused by a broad distribution of energy scales within any quantum Griffiths phase in itinerant systems.

description: Background: Geste antagoniste, or sensory trick, is a voluntary maneuver that temporarily reduces the severity of dystonic postures or movements. We present a historical review of early reports and illustrations of geste antagoniste. Results: In 1894, Brissaud described this phenomenon in Paris in patients with torticollis. He noted that a violent muscular contraction could be reversed by a minor voluntary action. He considered the improvement obtained by what he called “simple mannerisms, childish behaviour or fake pathological movements” was proof of the psychogenic origin of what he named mental torticollis. This concept was supported by photographical illustrations of the patients. The term geste antagoniste was used by Brissaud’s pupils, Meige and Feindel, in their 1902 monograph on movement disorders. Other reports and illustrations of this sign were published in Europe between 1894 and 1906. Although not mentioned explicitly, geste antagoniste was also illustrated in a case report of generalized dystonia in Oppenheim’s 1911 seminal description of dystonia musculorum deformans in Berlin. Discussion: Brissaud-Meige’s misinterpretation of the geste antagoniste unfortunately anchored the psychogenic origin of dystonia for decades. In New York, Herz brought dystonia back into the realm of organic neurology in 1944. Thereafter, it was given prominence by other authors, notably Fahn and Marsden in the 1970–1980s. Nowadays, neurologists routinely investigate for geste antagoniste when a dystonic syndrome is suspected, because it provides a further argument in favor of dystonia. The term alleviating maneuver was proposed in 2014 to replace sensory trick or geste antagoniste. This major sign is now part of the motor phenomenology of the 2013 Movement Disorder Society’s classification of dystonia.

description: Presentation given to Cambridge University Library staff as part of Open Access Week 2017. So-called predatory publishers regularly approach researchers via email to solicit manuscripts and conference papers. With the emphasis on publishing as a measure of academic success still strong it can be easy to give in to temptation and flattery but this can do more harm than good to a future career. This presentation looks at the problem of predatory publishers who exploit changes to the publishing landscape in the 21st century. Covering what a predatory publisher is, why they are a problem and including a handy checklist to help assess publishers this presentation is recommended for library staff working in research support roles.
Intermediate Phenotypes of ATP1A3 Mutations: Phenotype–Genotype Correlations
Creators: name: Termsarasab, Pichet

description: Background: ATP1A3-related disorders include rapid-onset dystonia–parkinsonism (RDP or DYT12), alternating hemiplegia of childhood (AHC), and CAPOS syndrome (Cerebellar ataxia, Areflexia, Pes cavus, Optic atrophy, and Sensorineural hearing loss). Case Report: We report two cases with intermediate forms between RDP and AHC. Patient 1 initially presented with the AHC phenotype, but the RDP phenotype emerged at age 14 years. The second patient presented with levodopa-responsive paroxysmal oculogyria, a finding never before reported in ATP1A3-related disorders. Genetic testing confirmed heterozygous changes in the ATP1A3 gene in both patients, one of them novel. Discussion: Intermediate phenotypes of RDP and AHC support the concept that these two disorders are part of a spectrum. We add our cases to the phenotype–genotype correlations of ATP1A3-related disorders.

description: Our pilot study investigated the feasibility of using virtual reality in peadiatric oncology centres. Results pointed to the positive psychological effects of virtual reality in paediatric oncology and it was well-integrated into hospital's life. Our second research aims to investigate our specific developed VR game impact compare with a standard VR game. Our participants are 12-18 years old children who get intravenous chemotherapy treatment and suffer from oncology disease. The most common types of disease among the participants: acute lymphoblastic leukaemia, Hodgkin lymphoma and osteosarcoma. We measure physical (electrodermal activity and heart rate variability) and psychological (STAI-Y) variables. During the statistical analysis we will use linear mixed modelling. We expect that our specific game can maximalise the wanted effect of virtual reality. Changelog: Version 0.1 - 02SEVR.zip - Available documents in Hungarian language.

description: The role of the selection pressure and mutation amplitude on the behavior of a single-species population evolving on a two-dimensional lattice, in a periodically changing environment, is studied both analytically and numerically. The mean-field level of description allows to highlight the delicate interplay between the different time-scale processes in the resulting complex dynamics of the system. We clarify the influence of the amplitude and period of the environmental changes on the critical value of the selection pressure corresponding to a phase-transition "extinct-alive" of the population. However, the intrinsic stochasticity and the dynamically-built in correlations among the individuals, as well as the role of the mutation-induced variety in population's evolution are not appropriately accounted for. A more refined level of description, which is an individual-based one, has to be considered. The inherent fluctuations do not destroy the phase transition "extinct-alive", and the mutation amplitude is strongly influencing the value of the critical selection pressure. The phase diagram in the plane of the population's parameters -- selection and mutation is discussed as a function of the environmental variation characteristics. The differences between a smooth variation of the environment and an abrupt, catastrophic change are also addressesd.

KIC 9406652: A laboratory for tilted disks in cataclysmic variable stars. II. Modeling of the orbital light curves

description: KIC 9406652, one of the recently identified IW And-type dwarf novae, is the best target for studying the tilted disk in cataclysmic variable stars. In a previous paper by Kimura, Osaki, and Kato (2020), we analyzed its Kepler light curves and found that its orbital light curves during the brightening stage were dominated by the reflection effect of the secondary star and varied with the orientation of the tilted disk; the amplitude was maximized at the minimum of the super-orbital signal and the phase of the light maximum shifted to an earlier one with the advance of the super-orbital phase. We argued there that this was the direct evidence of the retrogradely precessing tilted disk as the secondary star acts like a reflecting object. In order to confirm this interpretation, we have performed numerical modeling of orbital light curves in this paper. We have succeeded in reproducing the main characteristics of the observed orbital light curves by a simple model in which the secondary star is irradiated by the tilted disk. We have also constrained the inclination angle, $i$, of the binary system and the tilt angle, $θ$, of the disk purely from photometric considerations. The best-fitting parameter set is found to be $i \sim$45~deg and $θ\sim$2.0~deg, respectively. The orbital inclination thus estimated is consistent with that obtained from the spectroscopic considerations within the uncertainty limit. On the other hand, the tilt angle of the disk could be underestimated by using only the semi-amplitude of super-orbital signals.

description: Background: The pathophysiology of the movement disorder progressive ataxia with palatal tremor (PAPT) is unclear. Case report: A 77-year-old male presented with dysarthria, ataxia, and 1–2 Hz palatal tremor. A diagnosis of probable sporadic PAPT was established. Brain magnetic resonance imaging was normal at the presymptomatic phase but later showed olivary hypertrophy. Brain [18F]-fludeoxyglucose (FDG) positron emission tomography (PET) showed bilateral hypermetabolism in the olivary nuclei. Discussion: This second reported patient with PAPT and FDG-PET shows that olivary hypertrophy is paralleled with hypermetabolism. The olivary nuclei pathology also appears to be temporally associated with symptom onset.

description: Η καρδιαγγειακή νόσος παρατηρείται αργότερα στις γυναίκες σε σχέση με τους άνδρες και αυτό οδηγεί στη σκέψη ότι έλλειψη οιστρογόνων προδιαθέτει στις γυναίκες σε αυξημένο καρδιαγγειακό κίνδυνο. Η ραλοξιφαίνη(SERM) είναι μη ορμονικός παράγοντας με αγωνιστική δράση στα οστά και στις λιποπρωτεϊνες, αλλά ανταγωνιστική στο μαστό και στο ενδομήτριο. Μελετήθηκαν 12 υγιείς μετεμμηνοπαυσιακές γυναίκες που έλαβαν ραλοξιφαίνη 60mg ημερησίως για 12 μήνες και άλλες 14 γυναίκες που δεν έλαβαν φάρμακο με σκοπό να διερευνηθεί η επίδραη της ραλοξιφαίνης στους παράγοντες κινδύνου στεφανιαίας νόσου γινόταν αρχικά και μετά 12 μήνες, μέτρηση ΑΠ και σφύξεων, ηλεκτροκαρδιογράφημα, υπερηχογράφημα-doppler καρδιάς, δοκιμασία κοπώσεως, υπερηχογράφημα γεμμητικών οργάνων, μαστογραφία, και μέτρηση οστικής πυκνότητας. Στους 3,6 και 12 μήνες γινόταν αιματολογικός έλεγχος και μέτρηση : σακχάρου, ουρίας, ολικής χοληστερόλης, HDL και LDL χοληστερόλης, τριγλυκεριδίων, apoA, apoB, Lp(a), ομοκυστεϊνης, hsCRP, χρόνου προθρομβίνης και μερικής θρομβοπλαστίνης, ATIII, ινωδογόνο και DDimers. Τα αποτελέσματα έδειξαν ότι μόνο η ολική χοληστερόλη και η LDL, παρουσίασαν σημαντική πτώση ενώ οι υπόλοιπες παράμετροι δεν σημείωσαν μεταβολές. Συμπερασματικά η βραχυχρόνια χορήγηση ραλοξιφαίνης σε υγιείς μετεμμηνοπαυσιακές γυναίκες δεν επηρεάζει δυσμενώς τους παράγοντες κινδύνου στεφανιαίας νόσου
description: Coronary artery disease is observed later in women than men, and probably this lack of estrogens predisposes the women to intreased cardiovascular risk. Raloxifene(SERM) is a non hormonal factor, which have an agonistic action on the bones and lipoproteins, but an antagonistic one on the breast and the endometrium. Twelve healthy postmenopausal women received raloxifene(for 12 months 60mg daily) and other 14 women did not receive any therapy. with a view to studying the effect of raloxifene on the markers of risk for coronary artery disease at the beginning of the study and after 12 months, arterial pressure measurements and pulses were recorded, as well as, electrocardiogram, echo-cardiography-Doppler, treadmill exercise test, an ultrasound of the genital organs, mastography, and measurement of bone density. Also, at 3,6, and 12 months blood biochemical tests were performed which included : glucose, urea, total cholesterol, HDL, LDL cholesterol, triglycerides, apoA, apoB, Lp(a), homocysteine as well as full blood test. At the same time as the above mentioned time intervals the hsCRP, prothrombin time and partial thromboplastin, the ATIII, the fibrinogen and the D-Dimers, were measured. The results showed significant decrease in the total cholesterol and the LDL only and there were no other changes in the other parameters. In conclusion, the short-term administration of raloxifene to healthy postmenopausal women does not affect negatively the risk factors for coronary artery disease

description: A simple argument is given that a traversable Cauchy horizon inside a black hole is incompatible with unitary black hole evolution. The argument assumes the validity of black hole complementarity and applies to a generic black hole carrying angular momentum and/or charge. In the second part of the paper we review recent work on the semiclassical geometry of two-dimensional charged black holes.

description: Ενώ το ιταλικό εκπαιδευτικό σύστημα είναι αποκεντρωτικό, ως προς τις σχολικές μονάδες, στην Ελλάδα η εκπαιδευτική πολιτική σχεδιάζεται συγκεντρωτικά από το Υπουργείο. Στην Ιταλία ο προσανατολισμός ξεκινά νωρίτερα για τη δύσκολη και ταυτόχρονα δημιουργική περίοδο της προεφηβείας των μαθητών. Στην Ιταλία δίδεται διπλάσιος χρόνος για τη διδασκαλία της λογοτεχνίας σε σχέση με την Ελλάδα. Η σκηνοθεσία του μαθήματος για τους ιταλούς είναι η εκμάθηση της γλώσσας και η ευρύτερη αγωγή των νέων, ενώ για τους ελληνες η ανάδειξη της πολιτισμικής κληρονομιάς και η "οικείωση προς την ευρεία έννοια της λογοτενικότητας". Η αξιολόγηση των μαθητών στην Ιταλία είναι συχνή, συστηματική και σύνθετη, ενώ αντίστοιχα στην Ελλάδα κυριαρχεί η φορμαλιστική προσέγγιση των λογοτεχνικών κειμένων. Η επιμόρφωση των ειδικών καθηγητών στην Ιταλία είναι οργανωμένη και συστηματική, ενώ στην Ελλάδα στηρίζεται στα ολιγοήμερα επιμορφωτικά σεμινάρια. Τα εγχειρίδια στην Ιταλία επιλέγονται από τα κατά τόπους σχολεία, είναι πλούσια σε ύλη, ευρηματικά σε ασκήσεις, και κοντά στην ηλικία και ψυχολογία των μαθητών. Στα ελληνιλά διδακτικά βιβλία είναι εμφανής η λιτότητά του σχεδιασμού των μαθημάτων και η τυποποίηση του τρόπου επεξεργασίας τους. Οι καιροί απαιτούν τα εκπαιδευτικά συστήματα της Ευρώπης να δώσουν στην λογοτεχνία τη θέση που πραγματικά της αξίζει
description: While the italian educational system is highly decentralized, concerning the school units, the Ministry of Education tends to structure the learning policy in a centralized manner. In Italy the educational orientation stars early on so as to prepare young students for the laborious butr at the same time extremely creative period of their lives before entering puberty. Teachers in Italy also devote twice as much time as Greek teachers in instructing literature. The lesson objective for the language and the focusing on the further upbringing of the young. On the contrary greek people pay more attention on the elevation of the cultural heritage and attempt to familiarize students with the broader meaning of the literary notion. The evaluation of students progress in Italy is frequent, systematic and complex, whilst at the same time in Greece the formalistic approach of literary texts prevails. The further education of specially qyalified teachers in Italy is organized and very systematic while in Greece is based on short educational seminars. The teaching manuals in Italy which are being selected without restrictions by the local schools, include rich material, resourceful exercises and are closer to the age and the mentality of the students, so as to meet the needs of those who wish genuinely to learn. The Greek teaching books are frugal in lesson design and are propossed in a standardized fashion. Nowadays call for the educational systems of Europe to place literature in the position in truly deserves
