description: We investigate the existence of the meromorphic extension of the spectral zeta function of the Laplacian on self-similar fractals using the classical results of Kigami and Lapidus (based on the renewal theory) and new results of Hambly and Kajino based on the heat kernel estimates and other probabilistic techniques. We also formulate conjectures which hold true in the examples that have been analyzed in the existing literature.

description: We study the single spin asymmetries for the $πp^\uparrow\rightarrowμ^+μ^-X$ process. We consider the asymmetries contributed by the coupling of the Boer-Mulders function with the transversity distribution and the pretzelosity distribution, characterized by the $\sin(ϕ+ϕ_S)$ and $\sin(3ϕ-ϕ_S)$ azimuthal angular dependence, respectively. We estimate the magnitude of these asymmetries at COMPASS by using proper weighting functions. We find that the $\sin(ϕ+ϕ_S)$ asymmetry is of the size of a few percent and can be measured through the experiment. The $\sin(3ϕ-ϕ_S)$ asymmetry is smaller than the $\sin(ϕ+ϕ_S)$ asymmetry. After a cut on $q_T$, we succeed in enhancing the asymmetry.

description: The ALPS collaboration runs a "Light Shining through a Wall" (LSW) experiment to search for photon oscillations into "Weakly Interacting Sub-eV Particles" (WISPs) often predicted by extensions of the Standard Model. The experiment is set up around a superconducting HERA dipole magnet at the site of DESY. Due to several upgrades of the experiment we are able to place limits on the probability of photon-WISP-photon conversions of a few 10^{-25}. These limits result in today's most stringent laboratory constraints on the existence of low mass axion-like particles, hidden photons and minicharged particles.

description: On a Riemannian or a semi-Riemannian manifold, the metric determines invariants like the Levi-Civita connection and the Riemann curvature. If the metric becomes degenerate (as in singular semi-Riemannian geometry), these constructions no longer work, because they are based on the inverse of the metric, and on related operations like the contraction between covariant indices. In this article we develop the geometry of singular semi-Riemannian manifolds. First, we introduce an invariant and canonical contraction between covariant indices, applicable even for degenerate metrics. This contraction applies to a special type of tensor fields, which are radical-annihilator in the contracted indices. Then, we use this contraction and the Koszul form to define the covariant derivative for radical-annihilator indices of covariant tensor fields, on a class of singular semi-Riemannian manifolds named radical-stationary. We use this covariant derivative to construct the Riemann curvature, and show that on a class of singular semi-Riemannian manifolds, named semi-regular, the Riemann curvature is smooth. We apply these results to construct a version of Einstein's tensor whose density of weight 2 remains smooth even in the presence of semi-regular singularities. We can thus write a densitized version of Einstein's equation, which is smooth, and which is equivalent to the standard Einstein equation if the metric is non-degenerate.

description: Sustaining a large fraction of single GPU performance in parallel computations is considered to be the major problem of GPU-based clusters. In this article, this topic is addressed in the context of a lattice Boltzmann flow solver that is integrated in the WaLBerla software framework. We propose a multi-GPU implementation using a block-structured MPI parallelization, suitable for load balancing and heterogeneous computations on CPUs and GPUs. The overhead required for multi-GPU simulations is discussed in detail and it is demonstrated that the kernel performance can be sustained to a large extent. With our GPU implementation, we achieve nearly perfect weak scalability on InfiniBand clusters. However, in strong scaling scenarios multi-GPUs make less efficient use of the hardware than IBM BG/P and x86 clusters. Hence, a cost analysis must determine the best course of action for a particular simulation task. Additionally, weak scaling results of heterogeneous simulations conducted on CPUs and GPUs simultaneously are presented using clusters equipped with varying node configurations.

description: In this paper, we investigate the analytical solutions of the compressible Navier-Stokes equations with dependent-density viscosity. By using the characteristic method, we successfully obtain a class of drifting solutions with elliptic symmetry for the Navier-Stokes model wherein the velocity components are governed by a generalized Emden dynamical system. In particular, when the viscosity variables are taken the same as Yuen in [Yuen M.W. (2008), Analytical Solutions to the Navier-Stokes Equations, J. Math. Phys. 49, 113102], our solutions constitute a generalization of that obtained by Yuen.

description: In questo lavoro ho voluto affrontare il tema della riproduzione in seconda media cercando di creare un ambiente idoneo in cui gli allievi si sentissero liberi di scegliere delle tematiche relative a questo argomento e molti di loro si sono indirizzati verso la riproduzione umana. Il tema dell’educazione alla sessualità e all’affettività è molto ampio, delicato e quando si inizia ad affrontarlo con gli adolescenti di seconda media ci si rende conto di quante informazioni loro già sappiano, in maniera confusa oppure a volte errata, ma parlando con loro si percepisce la loro curiosità e l’imbarazzo che provano ad esporsi con gli adulti. In classe sono nati cinque gruppi di ricercatori che, dopo aver approfondito l’argomento prescelto, hanno presentato dapprima ai compagni il risultato del loro lavoro e, in seguito, agli allievi di un’altra seconda media. I vissuti degli allievi testimoniano quanto l’esperienza compiuta sia stata arricchente per tutti: per gli allievi che hanno potuto assumere ruoli significativi e apprendere in modo cooperativo situandosi al centro del processo di apprendimento, per me che ho potuto interagire con la classe assumendo un ruolo decentrato e scoprire nuovi lati della loro personalità.

Dalla semplicità della forma alla complessità del contenuto Illustrazione, con oggetti di vita quotidiana, dell’Inferno di Dante

description: L’intento di amplificare la comunicazione dell’Inferno di Dante Alighieri, tramite l’interazione con immagini, è invece la struttura portante. La mia tesi di laurea consiste nel comprendere quali siano i concetti principali presenti nella prima cantica della Divina Commedia, e di conseguenza le intenzioni comunicative del poeta fiorentino, per dare il mio contributo nella semplificazione della loro comprensione. Il processo di progettazione inizia con la lettura, l’analisi e la comprensione del poema, per poi approfondire le teorie che permettessero il raggiungimento degli obiettivi. In particolare, ho appreso quali siano i metodi di costruzione di una metafora nel testo visivo e le potenzialità comunicative del rapporto fra immagini e elementi testuali. La successiva applicazione di questi concetti teorici mi ha permesso di costituire un progetto coerente che si componesse di: un progetto fotografico still life che facesse uso esclusivo di oggetti di vita quotidiana; la produzione di un artefatto cartaceo che mettesse in relazione il testo del poeta con le immagini da me prodotte. Lo scopo di questo progetto è di concedere una lettura più semplice e contemporanea a un opera antica, e dai più considerata complessa come l’Inferno.
Transportation habits, motor fuel prices, and public support for carbon pricing in Canada

Publisher: name: University of British Columbia

description: This thesis explores the relationship between transportation habits, motor fuel prices, and public support for a carbon tax in Canada. It lies at the intersection of literatures on public opinion, environmental taxation, and climate politics. The thesis analyses an original panel survey conducted in five provinces around the implementation of the Canadian federal carbon tax in 2019. The thesis finds that driving as principal mode of transportation decreases support for a carbon tax by 11.3%, and an additional one cent increase in the price per litre of gasoline over the past month decreases support for a carbon tax by 0.3%. The thesis also finds that living in an urban center increases support for a carbon tax by 9.4% to 9.9% in Canada, as opposed to living outside of an urban center. This could be because more reliable transportation alternatives are available to urban dwellers. Partisanship is also found to have a strong effect on support for a carbon tax in Canada, in accordance with previous literature on the topic. The role of respondents’ overestimations of the impact of a carbon tax on gasoline prices is explored but remains inconclusive. Several avenues for future research on the matter are presented in this thesis.

description: The inspection of housing unit completion is the procedure used to verify if the conditions of real estate construction are consistent with the conception, design, and commercialization processes for the delivery of the property to the user who will become responsible for its use and conservation. Conventional inspections carried out for the delivery of housing units are commonly conducted through forms filled out on paper or on tablets, taking place without the construction companies' previous care regarding what must be presented to users in relation to the performance of the building. Compounding the situation, users, in general, do not have the knowledge of what should be checked at the time of the inspection, as they are mostly laymen. The Brazilian Performance Standard represents advances for the construction market but at the same time a challenge for its concepts to be incorporated by construction companies or for it to be used for the benefit of the user. Augmented Reality (AR) has the potential to make the inspection process more assertive and interactive, as it can guide and optimize the activity. AR is a technology that allows the superposition of virtual objects in a real environment, with online information, through visualization devices such as smartphones, tablets. The use of AR to incorporate performance parameters in the inspection of housing units can provide greater clarity to the user regarding what must be investigated with the inclusion of sensitive and perceptible aspects related to the potential performance of the property. The research was developed according to the criteria of Design Science Research, with the aim of producing an artifact that aims to solve practical problems and contribute to the production of knowledge. Aspects related to AR technology were researched, the inspection model of the housing unit completion was evaluated, and Performance Standard requirements were obtained so that they could be condensed and configured for an AR artifact for use in the inspection of housing unit completion. In the development of the AR artifact, a theoretical model was elaborated to produce a preliminary version and, based on the results achieved in the field tests and evaluations, an improved final version was obtained. Despite the limitations of the research, it was evident that the use of the artifact in AR allowed the inspection of housing unit completion to be carried out faster and with greater ease when compared to the conventional process: users had more interest and greater perception of details and access to the performance.

description: The Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLAST-Pol) is a suborbital mapping experiment designed to study the role played by magnetic fields in the star formation process. BLAST-Pol is the reconstructed BLAST telescope, with the addition of linear polarization capability. Using a 1.8 m Cassegrain telescope, BLAST-Pol images the sky onto a focal plane that consists of 280 bolometric detectors in three arrays, observing simultaneously at 250, 350, and 500 um. The diffraction-limited optical system provides a resolution of 30'' at 250 um. The polarimeter consists of photolithographic polarizing grids mounted in front of each bolometer/detector array. A rotating 4 K achromatic half-wave plate provides additional polarization modulation. With its unprecedented mapping speed and resolution, BLAST-Pol will produce three-color polarization maps for a large number of molecular clouds. The instrument provides a much needed bridge in spatial coverage between larger-scale, coarse resolution surveys and narrow field of view, and high resolution observations of substructure within molecular cloud cores. The first science flight will be from McMurdo Station, Antarctica in December 2010.

description: In questo lavoro si è voluto capire se la biblioteca scolastica di Scuola Media (SM) viene utilizzata dai docenti di inglese lingua straniera (LS) come mezzo per sfruttare i vantaggi offerti dalla lettura estensiva (ER). Nella parte teorica vengono illustrate le caratteristiche della biblioteca di sede, della ER, i vantaggi da loro offerti e gli strumenti didattici indispensabili in una biblioteca di SM. Nella parte pratica si sono analizzati i prestiti e le collezioni di quattro biblioteche di SM, svolgendo inoltre interviste semi-strutturate per completare l’analisi. Dai risultati ottenuti si è potuto constatare che i docenti di inglese LS utilizzano le biblioteche scolastiche come risorsa didattica per percorsi di ER. Ciononostante, il loro utilizzo potrebbe essere più omogeneo. La mancanza di uniformità potrebbe essere attribuita alle principali difficoltà legate al concetto di ER, tra cui la mancanza di tempo e di materiali adatti in inglese LS. Per far sì che l’utilizzo della biblioteca supporto didattico in grado di accompagnare i docenti verso percorsi di ER venga incentivato, si propone ai bibliotecari di dedicarsi maggiormente alla sezione di esemplari in inglese, focalizzandosi sul livello e i generi dei testi proposti e segnalando chiaramente la loro presenza. Inoltre, è necessario che docenti e bibliotecari si supportino a vicenda e sfruttino le risorse messe a disposizione da banche dati come MLOL. Relatore: Wolfgang Sahlfeld.

description: The Large Hadron Collider at CERN currently provides p$+$p collisions at center of mass energies of $\sqrt{s} = 7$~TeV, which allow to study high $\pT$ particle production and jet properties in a new energy regime. For a clear interpretation and the quantification of the medium influence in heavy-ion collisions on high $\pT$ observables a detailed understanding of these elementary reactions is essential. We present first results on the observation of jet-like properties with the ALICE experiment and discuss the performance of jet reconstruction in the first year of data taking.

description: The purpose of this paper is to generalize fermionic coherent states for two-level systems described by pseudo-Hermitian Hamiltonian \cite{Trifonov}, to n-level systems. Central to this task is the expression of the coherent states in terms of generalized Grassmann variables. These kind of Grassmann coherent states satisfy bi-overcompleteness condition instead of over-completeness one, as it is reasonably expected because of the biorthonormality of the system. Choosing an appropriate Grassmann weight function resolution of identity is examined. Moreover Grassmannian coherent and squeezed states of deformed group $SU_{q}(2)$ for three level pseudo-Hermitian system are presented.

description: I più recenti sviluppi nell’ambito del riconoscimento digitale dei caratteri, in particolar modo con l’introduzione di nuove tecniche di machine learning nei processi di visione artificiale, hanno permesso al computer di elaborare i dati raccolti dai sensori in modo più performante. Le macchine sono ora in grado di “vedere” in un modo che, si pensa, per certi aspetti è analogo a quello dell’uomo. Già oggi le macchine riescono a riconoscere testi presenti all’interno di immagini complesse e convertirli in formati che altre macchine sono in gradi di processare. Sapendo che questo nuovo consumatore di tipografia è in grado di leggere quello che gli umani scrivono, come cambierà il modo di fare tipografia in futuro? Il mio progetto di tesi è un contributo a questa domanda, NEMESI è un carattere tipografico che non può essere letto dal computer. Tanti sono oggi gli aspetti che concernono la sicurezza e la privacy dei dati negli ambienti digitali, altrettanti sono i pericoli che si ripercuotono nella realtà, quando questi dati vengono compromessi. L’uomo deve quindi poter comunicare libero dall’occhio osservatore del computer e per farlo deve conoscere i limiti della tecnologia e comprenderne il funzionamento. NEMESI sfida lo stato attuale del riconoscimento ottico dei caratteri e vuole dimostrare che anche le più recenti tecnologie hanno dei limiti.

description: Traffic professionals need to consistently evaluate all alternative intersection configurations and document intersection operational benefits. This information is vital to roadway designers who need to make informed decisions on whether to select a traditional or alternative intersection design and potentially choose among competing alternative intersection designs. Therefore, this study’s objective was to identify and assess proposed alternative intersection installations and their operational performance before construction was started (before period) and contrast traffic operations to conditions following the completion of construction (after period).

description: We present time-dependent solutions in the higher-dimensional gravity which are related to supergravity in the particular cases. Here, we consider p-branes with a cosmological constant and the intersections of two and more branes. The dynamical description of p-branes can be naturally obtained as the extension of static solutions. In the presence of a cosmological constant, we find accelerating solutions if the dilaton is not dynamical. In the case of intersecting branes, the field equations normally indicate that time-dependent solutions in supergravity can be found if only one harmonic function in the metric depends on time. However, if the special relation between dilaton couplings to antisymmetric tensor field strengths is satisfied, one can find a new class of solutions where all harmonic functions depend on time. We then apply our new solutions to study cosmology, with and without performing compactifications.

Ο ίδιος, ασχολήθηκε με τον τομέα των τεχνών δημιουργώντας αξιόλογα έργα σε ναούς στην ευρύτερη περιοχή της Κύμης όπως και στην οικία του. Σκοπός της παρούσας διπλωματικής εργασίας είναι η έρευνα της ζωής και των έργων του Σ. Χρυσανθόπουλου και ειδικότερα η μελέτη των τοιχογραφιών που διακοσμούν την οικία του. Η μελέτη αυτή, περιλαμβάνει τα αναλυτικά δεδομένα που συλλέχθηκαν μετά από την συστηματική in situ μελέτη των τοιχογραφιών μέσω μακροσκοπικής και μικροσκοπικής παρατήρησης, εφαρμογής θερμογραφίας (SWIR) και καταγραφής των περιβαλλοντικών συνθηκών. Ακολούθησαν οι μέθοδοι ανάλυσης των δειγμάτων με σκοπό τον προσδιορισμό των υλικών και της τεχνικής ζωγραφικής του καλλιτέχνη καθώς και την τεκμηρίωση της κατάστασης διατήρησης και της παθολογίας του τοιχογραφικού διάκοσμου. Στις μεθόδους ανάλυσης, περιλαμβάνονται η οπτική μικροσκοπία (ΟΜ), η ηλεκτρονική μικροσκοπία σάρωσης σε συνδυασμό με μικροανάλυση ακτίνων Χ (SEM-EDX), η μικρό φασματοσκοπία Raman (μ-Raman) και η φασματοσκοπία υπερύθρου με μετασχηματισμό Fourier (FTIR). Τα πειραματικά αποτελέσματα έδειξαν ότι η τεχνική που χρησιμοποίησε ο καλλιτέχνης είναι secco και η χρωματική του παλέτα αποτελείται από τις χρωστικές κόκκινο mars, κίτρινο του χρωμίου, πράσινο emerald, βερμιγιόν/ κιννάβαρι, κόκκινο του μολύβδου/ μίνιο, συνθετική ουλτραμαρίνα, μαύρο του άνθρακα, λευκό του ψευδαργύρου, ασβεστίτη και γύψο για την απόδοση του λευκού. Με βάση τα αποτελέσματα που προέκυψαν από την εργαστηριακή μελέτη, προτείνονται και οι ανάλογες επεμβάσεις συντήρησης. Μεταξύ των επεμβάσεων συντήρησης, προτείνεται να πραγματοποιηθεί η στερέωση των απολεπισμένων περιοχών της ζωγραφικής επιφάνειας. Για τον λόγο αυτό, πραγματοποιήθηκαν πειραματικές εφαρμογές σε δοκίμια τοιχογραφίας και εν συνεχεία σε σπαράγματα τοιχογραφίας της οικίας Χρυσανθόπουλου. Από την εξέταση των αποτελεσμάτων που προέκυψαν και την αποτίμηση της αποτελεσματικότητας των ακρυλικών διασπορών που εφαρμόστηκαν, επιλέχθηκε το βέλτιστο στερεωτικό που προσέφερε την καλύτερη δυνατή εφαρμογή, ενώ παράλληλα δεν προκάλεσε αλλοιώσεις στις φυσικές ιδιότητες των χρωστικών. Έτσι, προτείνεται ένα συγκεκριμένο υλικό για εφαρμογή στην μελλοντική στερέωση των τοιχογραφιών της οικίας Χρυσανθόπουλου.

description: This paper deals with the entanglement, as quantified by the negativity, of pure quantum states chosen at random from the invariant Haar measure. We show that it is a constant (0.72037) multiple of the maximum possible entanglement. In line with the results based on the concentration of measure, we find evidence that the convergence to the final value is exponentially fast. We compare the analytically calculated mean and standard deviation with those calculated numerically for pure states generated via pseudorandom unitary matrices proposed by Emerson et. al. [Science, 302, 3098, (2003)]. Finally, we draw some novel conclusions about the geometry of quantum states based on our result.

description: As a traditional Chinese medicine, strychnos alkaloids have wide effects including antitumor, analgesic, and anti-inflammatory. However, the therapeutic window of strychnos alkaloids is quite narrow due to potential neurotoxicity. Therefore, it is necessary to explore some efficient biomarkers to identify and predict the neurotoxicity induced by strychnos alkaloids and find a therapy to prevent the neurotoxicity of strychnos alkaloids. Based on the previous studies of our research team, 21 endogenous substances related to neurotoxicity were monitored in rats’ serum with HPLC-MS/MS and ELISA. Starting from these fundamentals, a Lasso-Logistic regression model was used to select efficient biomarkers from 21 endogenous substances to predict brain injury and verify the neuroprotective effect of peonies. Under the processing of the Lasso-Logistic regression model, 12 biomarkers were identified from 21 endogenous substances to predict the neurotoxicity induced by strychnos alkaloids. At the same time, the neuroprotective effect of peonies was further confirmed by evaluating the level of 12 biomarkers. The results indicated that the development of the Lasso-Logistic regression model would provide a new, simple and efficient method for the prediction and diagnosis of the neurotoxicity induced by strychnos alkaloids.

description: Αναμφισβήτητα ένας από τους πιο σημαντικούς παράγοντες που διαστρεβλώνουν την παγκόσμια οικονομία αλλά και την οικονομία της Ελλάδας είναι η φοροδιαφυγή. Ειδικότερα τα τελευταία χρόνια, στα χρόνια της βαθιάς οικονομικής κρίσης της χώρας μας το φαινόμενο της φοροδιαφυγής αλλά και όλων των συναφών μορφών παραοικονομίας έχει πάρει τεράστιες διαστάσεις με ανυπολόγιστες συνέπειες σε κοινωνικό-οικονομικό-πολιτισμικούς τομείς. Κύριο μέλημα της κάθε κυβέρνησης είναι η πάταξη του φαινόμενου αυτού αντιμετωπίζοντας άμεσα τις συνέπειες, συνήθως με νέα σκληρά φορολογικά μέτρα. Σκοπός της παρούσας μελέτης είναι η καταγραφή της αντίληψης των φορολογούμενων για τη φοροδιαφυγή και των παραγόντων που οδηγούν ή αποτρέπουν το άτομο από τη φοροδιαφυγή. Μέσα από πρωτογενή ποσοτική έρευνα οι ερωτώμενοι καλούνται να καταθέσουν τις στάσεις και τις αντιλήψεις τους για το φαινόμενο αυτό καθώς και τους παράγοντες εκείνους που αποτελούν κίνητρα ή αντικίνητρα της παράνομης αυτής πράξης.

description: Hintergrund: Der Stellenwert der dorsalen Reklination des Tibiaplateaus (tibialer Slope) hat in den letzten Jahren in der gelenkerhaltenden Kniegelenkschirurgie zugenommen. Methodik: In der vorliegenden Habilitationsschrift wurde der Einfluss des tibialen Slopes auf die sagittale Kniegelenksstabilität untersucht Ergebnisse: Es konnte gezeigt werden, dass der tibiale Slope ganz unterschiedliche Werte betragen kann, aber auch eine exzessive Ausprägung nicht zwingend einen Krankheitswert hat (Arbeit 2). Trotzdem spielt diese Ausprägung bei fast jeder Operation des Kniegelenkes eine Rolle, so dass der tibiale Slope im klinischen Alltag gemessen (Arbeit 1), in den Entscheidungsprozess einer operativen Indikationsstellung einbezogen (Arbeit 3, 4, 5, 6) und bei einem Therapieversagen korrigiert werden sollte (Arbeit 7). Zusammenfassung: Es konnte gezeigt werden, dass der tibiale Slope einen großen Einfluss sowohl auf die vordere als auch auf die hintere Kniegelenksstabilität hat. Dieses Wissen kann somit bereits im Vorfeld einer operativen Versorgung zur Identifikation von Risikopatienten für ein späteres Therapieversagen beitragen.

description: Enterobacter species are Gram-negative, non-spore-forming, facultative anaerobes typically motile due to the presence of peritrichous flagella. E. cloacae, the species responsible for the majority of Enterobacter infections in humans, is part of the intestinal microbiota and may cause infection in patients that have previously received antimicrobial therapy or who have been admitted to the Intensive Care Unit. E. cloacae may cause several infections, such as pneumonia, urinary tract, skin and soft tissue and intravascular infections. Infective Endocarditis (IE) is a rare disease with notable morbidity and mortality. Even though IE is rarely caused by E. cloacae, these infections can be problematic due to the relative lack of experience in their management. The purpose of this study was to systematically review all published cases of IE by E. cloacae in the literature. A systematic review of PubMed, Scopus and Cochrane library (through 14th November 2020) for studies providing epidemiological, clinical, microbiological as well as treatment data and outcomes of IE by E. cloacae was performed. A total of 20 studies, containing data of 20 patients, were included. A prosthetic valve was present in 27.8%. Mitral valve was the commonest infected site, followed by aortic valve. Diagnosis was facilitated by transthoracic and transesophageal echocardiography in 38.5% each, while the diagnosis was set at autopsy in 10%. Fever, sepsis, shock and immunologic phenomena were the most common clinical presentations, followed by heart failure. Aminoglycosides, cephalosporins and carbapenems were the most common antimicrobials used. Clinical cure was noted in 75%, while overall mortality was 30%. Development of shock and treatment with the combination of piperacillin with tazobactam were associated with overall mortality.

description: Recent experimental works demonstrated that the Anthropogenic Global Warming (AGW) hypothesis, embodied in a series of Intergovernmental Panel on Climate Change (IPCC) global climate models, is erroneous. These works prove that atmospheric carbon dioxide contributes only very moderately to the observed warming, and that there is no climatic catastrophe in the making, independent on whether or not carbon dioxide emissions will be reduced. In view of these developments, we discuss climate predictions for the XXIst century. Based on the solar activity tendencies, a new Little Ice Age is predicted by the middle of this century, with significantly lower global temperatures. We also show that IPCC climate models can't produce any information regarding future climate, due to essential physical phenomena lacking in those, and that the current budget deficit in many EU countries is mainly caused by the policies promoting renewable energies and other AGW-motivated measures. In absence of any predictable adverse climate consequences of carbon dioxide emissions, and with no predictable shortage of fossil fuels, we argue for recalling of all policies aimed at reducing carbon dioxide emissions and usage of expensive renewable energy sources. The concepts of carbon credits, green energy and green fuels should be abandoned in favor of productive, economically viable and morally acceptable solutions.

Για την ακρίβεια είναι κάτι το οποίο η ανθρωπότητα είχε να ζήσει περισσότερα από 100 χρόνια. Μέσα στα δύο αυτά χρόνια της πανδημίας οι οργανισμοί και οι επιχειρήσεις έπρεπε να βρουν τρόπους προκειμένου να μπορέσουν να συνεχίσουν την λειτουργία τους υπό αυτές τις δύσκολες καταστάσεις. Τα τελευταία χρόνια στην Ελλάδα έχουν συμβεί αρκετές μεγάλες αλλαγές στη δημόσια διοίκηση. Αρκετές σημαντικές αλλαγές προς την ηλεκτρονική διακυβέρνηση και το ψηφιακό μετασχηματισμό οι οποίες θα έπρεπε βέβαια να έχουν ήδη γίνει εδώ και καιρό. Αντικείμενο αυτής της διπλωματικής είναι η μελέτη των ενεργειών οι οποίες έχουν ως στόχο τον ψηφιακό μετασχηματισμό της ελληνικής δημόσιας διοίκησης το τελευταίο διάστημα ως αποτέλεσμα των αυξημένων αναγκών που προκάλεσε η πανδημία.

description: Individualization of fosfomycin dosing based on therapeutic drug monitoring (TDM) of plasma concentrations could reduce drug-related adverse events and improve clinical outcome in complex clinical conditions. Quantification of fosfomycin in plasma samples was performed by a rapid ultraperformance liquid chromatography mass spectrometry method. Sample preparation involved protein precipitation with [13C3]-fosfomycin benzylamine salt as internal standard. The calibration curve ranged from 2 to 800 mg/L. Within- and between-day precision and accuracy, sensitivity, selectivity, dilution integrity, recovery were investigated and the results met the acceptance criteria. In patients, multiple drug dosing (every 6 or 8 hours) or in continuous administration were adopted, resulting in a large interpatient variability in drug concentrations (from 7.4 mg/L and 644.6 mg/L; CV: 91.1%). In critical care patient setting TDM can represent an important tool to identify the best fosfomycin dosing in single patients, taking into consideration clinical characteristics, infection sites and susceptibility of the treated pathogens.

description: We present a Chandra observation of the exceptional planet bearing A5V star HR 8799, more precisely classified as a kA5hF0mA5 star and search for intrinsic X-ray emission. We clearly detect HR 8799 at soft X-ray energies with the ACIS-S detector in a 10 ks exposure; minor X-ray brightness variability is present during the observation. The coronal plasma is described well by a model with a temperature of around 3 MK and an X-ray luminosity of about Lx = 1.3 x 10^28 erg/s in the 0.2-2.0 keV band, corresponding to an activity level of log Lx/Lbol ~ -6.2. Altogether, these findings point to a rather weakly active and given a RASS detection, long-term stable X-ray emitting star. The X-ray emission from HR 8799 resembles those of a late A/early F-type stars, in agreement with its classification from hydrogen lines and effective temperature determination and thus resolving the apparent discrepancy with the standard picture of magnetic activity that predicts mid A-type stars to be virtually X-ray dark.

description: Magnetotransport measurements on a high-mobility electron bilayer system formed in a wide GaAs quantum well reveal vanishing dissipative resistance under continuous microwave irradiation. Profound zero-resistance states (ZRS) appear even in the presence of additional intersubband scattering of electrons. We study the dependence of photoresistance on frequency, microwave power. and temperature. Experimental results are compared with a theory demonstrating that the conditions for absolute negative resistivity correlate with the appearance of ZRS.
