description: Η Αθηνά, μία από τις σημαντικότερες θεές των αρχαίων Ελλήνων, λατρεύτηκε σε όλο τον ελλαδικό χώρο και ιδιαίτερα στην πόλη των Αθηνών. Η λατρεία της ανάγεται στα τέλη του 8ου και στις αρχές του 7ου π. Χ. αιώνα και είχε κυρίως αστικό χαρακτήρα. Ιδιαίτερο ενδιαφέρον παρουσιάζουν οι μύθοι που αφορούν τη γέννησή της, το χαρακτήρα της και τη σχέση της με τους ανθρώπους. Η θεά λατρεύτηκε αρχικά ως χθόνια και αργότερα εξελίχθηκε σε ουράνια θεότητα, προστάτρια της πόλης και της δημόσιας ζωής. Το κοινό στοιχείο της λατρείας στον ελλαδικό χώρο ήταν αυτό της Πολιάδος, της προστάτριας θεάς της πόλης. Η λατρεία στην Ακρόπολη των Αθηνών ήλθε στο προσκήνιο στα τέλη του 6ου και στις αρχές του 5ου π.Χ. αιώνα, όταν άρχισαν να κτίζονται οι μεγαλειώδεις ναοί και να κατασκευάζονται εξαιρετικά αγάλματα. Καθώς οι ναοί και τα αγάλματα συνδέονταν με την υπόσταση της Αθηνάς ο Παρθενώνας ήταν ο ναός της Παρθένου ενώ το Ερέχθειο ο ναός της Πολιάδος, της κυρίαρχης θεότητας της πόλης. Αναπόσπαστο τμήμα της λατρείας της ήταν οι εορτές με πιο γνωστή αυτή των Παναθηναίων. Οι γιορτές είχαν ως σκοπό να ενισχύσουν το δεσμό της πόλης με την Αθηνά. Στο Σούνιο και στην υπόλοιπη Αττική η λατρεία της δεν διέφερε, η θεά λατρευόταν μόνη της ή μαζί με άλλες θεότητες. Από τη λατρεία της στο χώρο των Αθηνών και της Αττικής η θεά έκανε γνωστή την ειρηνική και ταυτόχρονα την πολεμική της υπόσταση.
description: Athena, one of the most important goddesses of the ancient Greeks, was worshipped throughout the Hellenic region and, especially, in the city of the Athenians. The origins of her cult date back to the end of the 8th and the beginning of the 7th century B.C., and her worship, mostly, had an urban character. The myths regarding her birth, character and relationship with mortal humans raise a special interest. At first, the goddess was worshipped as chthonic, but, later, was converted into a heavenly deity, protector of the city and public life. The common element of the cult in the Hellenic domain was that of the Polias, the patron-goddess of the city. Her worship in Acropolis, Athens, emerged in the end of the 6th and the beginning of the 5th century B.C., at the time when majestic temples were constructed and excellent sculptures created. Since there was a connection between the temples, sculptures and Athena’s personality, the Parthenon was the temple of the Parthenos, while the Erechtheum, the temple of the Polias; the dominant deity of the city. The religious celebrations, were an integral part of her cult, the most well-known being that of the Panathenaea. The purpose of the celebrations was to reinforce the bond between the polis and Athena. In Sounion and the rest of Attica, her worship didn’t differ; the goddess was either worshipped separately or along with other deities. Out of her worship in the area of Athens and Attica, in general, the goddess became known for her peaceful and warlike, twofold nature.

description: Despite the advantages of using biodegradable metals in implant design, their uncontrolled degradation and release remain a challenge in practical applications. A validated computational model of the degradation process can facilitate the tuning of implant biodegradation by changing design properties. In this study, a physicochemical model was developed by deriving a mathematical description of the chemistry of magnesium biodegradation and implementing it in a 3D computational model. The model parameters were calibrated using the experimental data of hydrogen evolution by performing a Bayesian optimization routine. The model was validated by comparing the predicted change of pH in saline and buffered solutions with the experimentally obtained values from corrosion tests, showing maximum 5% of difference, demonstrating the model's validity to be used for practical cases.

description: Monte Carlo data of the two-dimensional Ising spin glass with bimodal interactions are presented with the aim of understanding the low-temperature physics of the model. An analysis of the specific heat, spin-glass susceptibility, finite-size correlation length, and the Binder ratio is performed to try to verify a recent proposal in which for large system sizes and finite but low temperatures the effective critical exponents are identical to the critical exponents of the two-dimensional Ising spin glass with Gaussian interactions. Our results show that with present system sizes the recently proposed scenario in which the two-dimensional Ising spin glass with bimodally distributed interactions is in the same universality class as the model with Gaussian-distributed disorder at low but finite temperatures cannot be reliably proven.

description: A new parametrization of the 3-metric allows to find explicitly a York map in canonical ADM tetrad gravity, the two pairs of physical tidal degrees of freedom and 14 gauge variables. These gauge quantities (generalized inertial effects) are all configurational except the trace ${}^3K(τ,\vec σ)$ of the extrinsic curvature of the instantaneous 3-spaces $Σ_τ$ (clock synchronization convention) of a non-inertial frame. The Dirac hamiltonian is the sum of the weak ADM energy $E_{ADM} = \int d^3σ{\cal E}_{ADM}(τ,\vec σ)$ (whose density is coordinate-dependent due to the inertial potentials) and of the first-class constraints. Then: i) The explicit form of the Hamilton equations for the two tidal degrees of freedom in an arbitrary gauge: a deterministic evolution can be defined only in a completely fixed gauge, i.e. in a non-inertial frame with its pattern of inertial forces. ii) A general solution of the super-momentum constraints, which shows the existence of a generalized Gribov ambiguity associated to the 3-diffeomorphism gauge group. It influences: a) the explicit form of the weak ADM energy and of the super-momentum constraint; b) the determination of the shift functions and then of the lapse one. iii) The dependence of the Hamilton equations for the two pairs of dynamical gravitational degrees of freedom (the generalized tidal effects) and for the matter, written in a completely fixed 3-orthogonal Schwinger time gauge, upon the gauge variable ${}^3K(τ,\vec σ)$, determining the convention of clock synchronization. Therefore it should be possible (for instance in the weak field limit but with relativistic motion) to try to check whether in Einstein's theory the {\it dark matter} is a gauge relativistic inertial effect induced by ${}^3K(τ,\vec σ)$.

description: We study the anomalous conductance plateau around $G = 0.7(2e^{2}/h)$ and the zero-bias anomaly in ballistic hole quantum wires with respect to in-plane magnetic fields applied parallel $B_{\parallel}$ and perpendicular $B_{\perp}$ to the quantum wire. As seen in electron quantum wires, the magnetic fields shift the 0.7 structure down to $G = 0.5(2e^{2}/h)$ and simultaneously quench the zero bias anomaly. However, these effects are strongly dependent on the orientation of the magnetic field, owing to the highly anisotropic effective Landé \emph{g}-factor $g^{*}$ in hole quantum wires. Our results highlight the fundamental role that spin plays in both the 0.7 structure and zero bias anomaly.

description: The aim of this focus letter is to present a comprehensive classification of the main entropic forms introduced in the last fifty years in the framework of statistical physics and information theory. Most of them can be grouped into three families, characterized by two-deformation parameters, introduced respectively by Sharma, Taneja, and Mittal (entropies of degree $(α,\,β$)), by Sharma and Mittal (entropies of order $(α,\,β)$), and by Hanel and Thurner (entropies of class $(c,\,d)$). Many entropic forms examined will be characterized systematically by means of important concepts such as their axiomatic foundations {\em à la} Shannon-Khinchin and the consequent composability rule for statistically independent systems. Other critical aspects related to the Lesche stability of information measures and their consistency with the Shore-Johnson axioms will be briefly discussed on a general ground.

description: We study asymptotic properties of the Green metric associated with transient random walks on countable groups. We prove that the rate of escape of the random walk computed in the Green metric equals its asymptotic entropy. The proof relies on integral representations of both quantities with the extended Martin kernel. In the case of finitely generated groups, where this result is known (Benjamini and Peres [Probab. Theory Related Fields 98 (1994) 91--112]), we give an alternative proof relying on a version of the so-called fundamental inequality (relating the rate of escape, the entropy and the logarithmic volume growth) extended to random walks with unbounded support.

description: A method to generate long-lived isomeric states effectively for Mossbauer applications is reported. We demonstrate that this method is better and easier to provide highly sensitive Mossbauer effect of long-lived isomers (>1ms) such as 103Rh. Excitation of (gamma,gamma) process by synchrotron radiation is painful due mainly to their limited linewidth. Instead,(gamma,gamma') process of bremsstrahlung excitation is applied to create these long-lived isomers. Isomers of 45Sc, 107Ag, 109Ag, and 103Rh have been generated from this method. Among them, 103Rh is the only one that we have obtained the gravitational effect at room temperature.

description: When fluid is confined between two molecularly smooth surfaces to a few molecular diameters, it shows a large enhancement of its viscosity. From experiments it seems clear that the fluid is squeezed out layer by layer. A simple solution of the Stokes equation for quasi-two-dimensional confined flow, with the assmption of layer-by-layer flow is found. The results presented here correct those in Phys. Rev. B, 50, 5590 (1994), and show that both the kinematic viscosity of the confined fluid and the coefficient of surface drag can be obtained from the time dependence of the area squeezed out. Fitting our solution to the available experimental data gives the value of viscosity which is ~7 orders of magnitude higher than that in the bulk.

Organizing community economic development in an inner-city neighbourhood: a case study
Creators: name: Kemp, Leslie
Publisher: name: University of British Columbia
Year: 2008

description: This is a case study of a project focused on organizing community economic development (CED) in the inner-city neighbourhood of Mount Pleasant, in Vancouver. Participant-observation research techniques, combining the roles of organizer and researcher, were used in this exploratory study. The ethnic and cultural diversity of this inner-city neighbourhood, with its various "communities of interest, “presents challenges to CED organization. This study examines these challenges in relation to the process of organizing CED and identifies the relevant factors for determining a community's readiness for CED. Key aspects of the organizing process are explored in depth (e.g., gaining legitimacy within the community, assessing the community’s readiness for CED, determining a development approach, cultivating leadership and developing an organizational base). This study proposes a framework for organizing CED which identifies the major stages, activities and critical factors in organizing CED. The research identifies and discusses the major roles of the organizer and the beliefs and values which guided the organizing process.

description: We report on experiments aimed at comparing the hysteretic response of a Cu-Zn-Al single crystal undergoing a martensitic transition under strain-driven and stress-driven conditions. Strain-driven experiments were performed using a conventional tensile machine while a special device was designed to perform stress-driven experiments. Significant differences in the hysteresis loops were found. The strain-driven curves show re-entrant behaviour (yield point) which is not observed in the stress-driven case. The dissipated energy in the stress-driven curves is larger than in the strain-driven ones. Results from recently proposed models qualitatively agree with experiments.

description: Jovian planet formation has been shown to be strongly correlated with host star metallicity, which is thought to be a proxy for disk solids. Observationally, previous works have indicated that jovian planets preferentially form around stars with solar and super solar metallicities. Given these findings, it is challenging to form planets within metal-poor environments, particularly for hot Jupiters that are thought to form via metallicity-dependent core accretion. Although previous studies have conducted planet searches for hot Jupiters around metal-poor stars, they have been limited due to small sample sizes, which are a result of a lack of high-quality data making hot Jupiter occurrence within the metal-poor regime difficult to constrain until now. We use a large sample of halo stars observed by TESS to constrain the upper limit of hot Jupiter occurrence within the metal-poor regime (-2.0 $\leq$ [Fe/H] $\leq$ -0.6). Placing the most stringent upper limit on hot Jupiter occurrence, we find the mean 1-$σ$ upper limit to be 0.18 $\%$ for radii 0.8 -2 R$_{\rm{Jupiter}}$ and periods $0.5- 10$ days. This result is consistent with previous predictions indicating that there exists a certain metallicity below which no planets can form.

description: We have identified the three prominent routes, namely Heagy-Hammel, fractalization and intermittency routes, and their mechanisms for the birth of strange nonchaotic attractors (SNAs) in a quasiperiodically forced electronic system constructed using a negative conductance series LCR circuit with a diode both numerically and experimentally. The birth of SNAs by these three routes is verified from both experimental and their corresponding numerical data by maximal Lyapunov exponents, and their variance, Poincaré maps, Fourier amplitude spectrum, spectral distribution function and finite-time Lyapunov exponents. Although these three routes have been identified numerically in different dynamical systems, the experimental observation of all these mechanisms is reported for the first time to our knowledge and that too in a single second order electronic circuit.

description: Single carbon pellet disruption mitigation simulations using M3D-C1 were conducted in an NSTX-U-like plasma to support the electromagnetic pellet injection concept (EPI). A carbon ablation model has been implemented in M3D-C1 and tested with available data. 2D simulations were conducted in order to estimate the amount of carbon needed to quench the plasma, finding that the content in a $1\,$mm radius vitreous carbon pellet (~ 3.2x10E20 atoms) would be enough if it is entirely ablated. 3D simulations were performed, scanning over pellet velocity and parallel thermal conductivity, as well as different injection directions and pellet concepts (solid pellets and shell pellets). The sensitivity of the thermal quench and other related quantities to these parameters has been evaluated. A 1 mm radius solid pellet only partially ablates at velocities of 300 m/s or higher, thus being unable to fully quench the plasma. To further enhance the ablation, approximations to an array of pellets and the shell pellet concept were also explored. 3D field line stochastization plays an important role in both quenching the center of the plasma and in heat flux losses, thus lowering the amount of carbon needed to mitigate the plasma when compared to the 2D case. This study constitutes an important step forward in `predict-first' simulations for disruption mitigation in NSTX-U and other devices, such as ITER.

description: The letter considers non-isothermal fluid flows and revises simplifications of basic hydrodynamic equations for such flows arriving eventually to a generalization of the Oberbeck-Boussinesq approximation valid for arbitrary equation of state including both non-ideal gases as well as liquids. The proposed approach is based on a suggested general definition of potential temperature. Special attention is put on the energy conservation principle, and it is shown that the proposed approximation exactly preserves the total mechanical energy by approximate equations of motion. The principal importance for any turbulent boundary layer model to respect the conservation laws is emphasized explicitly.

description: We report on the effects of electron collision and indirect ionization processes, occurring at photoexcitation and electron kinetic energies well below 30 eV on the photoemission spectra of liquid water. We show that the nascent photoelectron spectrum and, hence, the inferred electron binding energy can only be accurately determined if electron energies are large enough that cross sections for quasi-elastic scattering processes, such as vibrational excitation, are negligible. Otherwise, quasi-elastic scattering leads to strong, down-to-few-meV kinetic energy scattering losses from the direct photoelectron features, which manifest in severely distorted intrinsic photoelectron peak shapes. The associated cross-over point from predominant (known) electronically inelastic to quasi-elastic scattering seems to arise at surprisingly large electron kinetic energies, of approximately 10-14 eV. Concomitantly, we present evidence for the onset of indirect, autoionization phenomena (occurring via superexcited states) within a few eV of the primary and secondary ionization thresholds. These processes are inferred to compete with the direct ionization channels and primarily produce low-energy photoelectrons at photon and electron impact excitation energies below ~15 eV. Our results highlight that vibrational inelastic electron scattering processes and neutral photoexcitation and autoionization channels become increasingly important when photon and electron kinetic energies are decreased towards the ionization threshold. Correspondingly, we show that for neat water and aqueous solutions, great care must be taken when quantitatively analyzing photoelectron spectra measured too close to the ionization threshold. Such care is essential for both the accurate determination of solvent and solute ionization energies as well as photoelectron branching ratios and peak magnitudes.

description: Το ωοθηκικό ενδομητρίωμα είναι μια κύστη των ωοθηκών που εμφανίζεται σε γυναίκες αναπαραγωγικής ηλικίας και επηρεάζει τη γονιμότητα. Αν και η ακριβής αιτία της ενδομητρίωσης δεν είναι γνωστή, θεωρείται ότι προκαλεί μείωση των ωοθηκικών εφεδρειών, κάτι που επηρεάζει αρνητικά την μελλοντική αναπαραγωγική ικανότητα. ‘Οσον αφορά τη χειρουργική αντιμετώπιση, η λαπαροσκοπική προσέγγιση αποτελεί την θεραπεία εκλογής, δεδομένου ότι συνοδεύεται από αναντίρρητα πλεονεκτήματα. Ένα θεμελιώδες ερώτημα αφορά την επιλογή του καταλληλότερου τρόπου αντιμετώπισης, ο οποίος να συνοδεύεται από μικρότερη επίπτωση στις ωοθηκικές εφεδρείες αλλά και στην ύφεση των συμπτωμάτων, καθώς και στην πιθανότητα υποτροπής. Σε αυτή την ανασκόπηση θα αξιολογηθούν διάφοροι τρόποι αντιμετώπισης, καθώς και η επίπτωση τους σε λειτουργικούς και υπερηχογραφικούς δείκτες, όπως αυτοί εκφράζονται με τους δείκτες της αντιμυλλέριου ορμόνης (ΑΜΗ - Anti-Müllerian Hormone) και του προσδιορισμού καταβολών ωοθυλακίων (AFC – Antral Follicle Count).
description: Ovarian endometrioma is a cyst of the ovaries, that affects the women of reproductive age and constitutes a factor of infertility. Although the exact cause is unknown, it is believed that it reduces the ovarian reserve, fact that negatively affects the future fertility. As far as the surgical treatment is concerned, the laparoscopic procedure is the gold standard, due to its numerous advantages. A major issue is the best treatment, that will have less impact on the ovarian reserve, low recurrence rates and reduction of the symptoms. In this review, several treatment paths will be evaluated, together with functional and ultrasound markers, such as AFC (Antral Follicle Count) and AMH (Anti-Müllerian Hormone)

The latter also gave the universities more decision-making autonomy, which goes hand in hand with more responsibilities, but also with the possibility of individualizing their strategy. This thesis examines how German universities can use Data Mining techniques to extract useful information from their available data resources to address these current challenges by supporting management decisions. The use of Data Mining methods in education is called Educational Data Mining. Research in this area has so far focused mainly on supporting students and lecturers. This thesis focuses on researching the benefits of Educational Data Mining for university management, which has been mentioned several times in various Educational Data Mining studies but has not been studied in detail so far. After discussing the most important challenges faced by German universities, their current tasks and objectives were examined. A framework model was then developed that illustrates how the results of two specific Data Mining projects can help universities tackle the challenges and accomplish their tasks. The selected Data Mining projects are dropout analysis and enrollment prediction because the student and applicant data are available to all the German universities. The proposed framework model was verified with two case studies in which the specified analyses were carried out at a German university of applied sciences. To build well-performing models, several Data Mining methods were used and compared. Subsequently, the results were discussed with representatives from the case university, and suggestions were made how the information generated could be included in the decisions of the university administration. It has been shown that German universities can use their data resources to support their management activities. An overview of this support was presented in the form of a framework model that is not only a first attempt to close the existing research gap in the field of EDM but should also mo-tivate university decision-makers to use their existing data resources. Therefore, the presented thesis can stimulate further research that combines the results of EDM projects with managerial decisions to increase the efficiency of educational institutions. In addition, university administrators can be inspired to use all available resources to ensure their long-term success.

description: We reanalyze deep star counts in five CADIS fields. The data are presented as vertical density distributions of stars perpendicular to the Galactic plane. In three fields the profiles are consistent with each other, while in two fields significant overdensities of stars are found. The overdensity in one field can be associated with the Virgo overdensity which can be traced right into the disk of the Milky Way. Using this detection we estimate the mass of the Virgo overdensity and show that this is equivalent to the stellar content of a Local Group dwarf spheroidal galaxy. The overdensity in the second field is more difficult to associate with a previously known overdensity. We suggest that it is related both to the Monoceros stream and the recently discovered Orphan stream.

description: Chemical modelling serves two purposes in dynamical models: accounting for the effect of microphysics on the dynamics and providing observable signatures. Ideally, the former must be done as part of the hydrodynamic simulation but this comes with a prohibitive computational cost which leads to many simplifications being used in practice. To produce a statistical emulator that replicates a full chemical model capable of solving the temperature and abundances of a gas through time. This emulator should suffer only a minor loss of accuracy over including a full chemical solver in a dynamical model but would have a fraction of the computational cost. The gas-grain chemical code UCLCHEM was updated to include heating and cooling processes and a large dataset of model outputs from possible starting conditions was produced. A neural network was then trained to map directly from inputs to outputs. Chemulator replicates the outputs of UCLCHEM with an overall mean squared error (MSE) of 0.0002 for a single time step of 1000 yr and is shown to be stable over 1000 iterations with an MSE of 0.003 the log scaled temperature after one time step and 0.006 after 1000 time steps. Chemulator was found to be approximately 50,000 times faster than the time dependent model it emulates but can introduce a significant error to some models.

description: Low frequency ionization oscillations involving plasma and neutral density (breathing modes) are the most violent perturbations in Hall thrusters for electric propulsion. Because of its simplicity, the zero-dimensional (0-D) predator-prey model of two nonlinearly coupled ordinary differential equations for plasma and neutral density has been often used for the characterization of such oscillations and scaling estimates. We investigate the properties of its continuum analog, the one-dimensional (1-D) system of two nonlinearly coupled equations in partial derivatives (PDE) for plasma and neutral density. This is a more general model, of which the standard 0-D predator-prey model is a special limit case. We show that the 1-D model is stable and does not show any oscillations for the boundary conditions relevant to Hall thruster and the uniform ion velocity. We then propose a reduced 1-D model based on two coupled PDE for plasma and neutral densities that is unstable and exhibit oscillations if the ion velocity profile with the near the anode back-flow (toward the anode) region is used. Comparisons of the reduced model with the predictions of the full model that takes into account the self-consistent plasma response show that the main properties of the breathing mode are well captured. In particular, it is shown that the frequency of the breathing mode oscillations is weakly dependent on the final ion velocity but shows a strong correlation with the width of the ion back-flow region.

description: Ο στόχος της παρούσας εργασίας είναι η διερεύνηση του μηχανισμού της σύμφυρσης (blending) στη Νέα Ελληνική. Πιο συγκεκριμένα, αυτό που κυρίως μας απασχολεί είναι τα μορφοφωνολογικά χαρακτηριστικά των προϊόντων της σύμφυρσης, των μιγμάτων (blends). Για να καταστεί εφικτή η μελέτη της συγκεκριμένης διαδικασίας έχει συσταθεί, στο πλαίσιο της παρούσας έρευνας, ένα corpus που αποτελείται από 200 μίγματα της Νέας Ελληνικής, τόσο της Κοινής Νεοελληνικής όσο και διαλέκτων. Αφού αποσαφηνιστεί και οριοθετηθεί ο όρος μίγμα για την Ελληνική, δίνεται βαρύτητα στην αναλυτική περιγραφή των μορφοφωνολογικών χαρακτηριστικών των μιγμάτων που αποτελούν το corpus και στην κατηγοριοποίηση των μιγμάτων με βάση γλωσσολογικά και κυρίως, μορφοφωνολογικά κριτήρια. Από τη μελέτη των δεδομένων προκύπτει ότι η σύμφυρση αποτελεί μια διαδικασία που διέπεται από κανόνες κι εμφανίζει συστηματικότητα σε διάφορα επίπεδα (π.χ. μέγεθος του μίγματος, θέση του τόνου) καθώς αποτελεί μέρος της μορφολογίας και γενικότερα, της γραμματικής. Μετά την ολοκλήρωση της όσο το δυνατόν αναλυτικότερης περιγραφής του μηχανισμού της σύμφυρσης και των χαρακτηριστικών των μιγμάτων που απαρτίζουν το corpus, πραγματοποιείται μια αναφορά στις φωνολογικές αναλύσεις που έχουν προταθεί για τα μίγματα με βάση τη Θεωρία του Βέλτιστου (Optimality Theory) και προτείνεται, με βάση το συγκεκριμένο θεωρητικό πλαίσιο, ένας νέος τρόπος ανάλυσης μιας συγκεκριμένης ομάδας μιγμάτων του corpus.
description: The aim of this thesis is the investigation of the mechanism of blending in Modern Greek. More specifically, we examine the morphophonological characteristics of greek blends. In order to achieve this, a corpus consisted of 200 blends of Modern Greek and its dialects has been constructed for the needs of the thesis. After the clarification and definition of the term blending in Greek, the emphasis is given to the analytical description of the morphophonological properties of the blends which constitute the corpus and the classification of these blends according to linguistic and mainly, morphophonological criteria. Our findings suggest that that blending is a rule-governed process which is part of morphology and generally, grammar and as a result exhibits systematicity in various levels (e.g. stress position, blend size). Finally, we refer to the phonological analyses based on Optimality Theory that have been proposed for blends and suggest a new analysis for a specific part of our data using the same theoretical framework.
The NADP-dependent glutamate dehydrogenase of Giardia lamblia: a study of function, gene structure, and expression
Creators: name: Yee, Janet
Publisher: name: University of British Columbia
Year: 2008

description: Giardia lamblia is an interesting organism in several respects. Not only is it a medically important protozoan parasite, but its location in the phylogenetic tree is at a critical and informative position. Characterization of its subcellular structure and rRNA sequences suggest that Giardia is one the most primitive eukaryotes known. Giardia has an anaerobic metabolism that uses a NADP-dependent glutamatede hydrogenase (GDH) along with alanine aminotransferase to maintain an intracellular balance of NAD(P)+-NAD(P)H through the conversion of pyruvate to alanine. In the initial part of this study, the Giardia NADP-GDH gene was cloned and characterized. The Giardia NADP-GDH is encoded by a single copy gene in the haploid genome. Transcript mapping and comparisons of the cDNA and genomic clones for the GDH gene did not detect the presence of introns or transsplicing. GDH transcripts have short untranslated sequences and are initiated only three to six nucleotides in front of the ATG translation initiation codon. In the latter part of this study, the 5' flanking sequence of the Giardia GDH gene was analyzed to identify possible promoter elements since core promoter elements normally associated with RNA polymerase II transcription in higher eukaryotes are not found in the upstream sequence of the GDH gene or in other Giardia genes. Two novel sequence motifs were identified, an AT-rich element and a Giardia CAAT-box-like sequence called the g-CAB element. Their conservation and locations relative to the sites of transcription initiation suggest that these elements may be involved in the regulation of transcription. A 68 kD protein binds to the TTT trinucleotides found on either one or both strands of the DNA encoding these elements from the upstream region of the GDH gene. This 68 kD protein is referred to as POT for its ply(T) binding ability. The function of POT may be to help denature the DNA at the promoter region and to participate in the assembly of the RNA polymerase II pre-initiation complex in Giardia.

description: Germanium is the detector material of choice in many rare-event searches looking for low-energy nuclear recoils induced by dark matter particles or neutrinos. We perform a systematic exploration of its quenching factor for sub-keV nuclear recoils, using multiple techniques: photo-neutron sources, recoils from gamma-emission following thermal neutron capture, and a monochromatic filtered neutron beam. Our results point to a marked deviation from the predictions of the Lindhard model in this mostly unexplored energy range. We comment on the compatibility of our data with low-energy processes such as the Migdal effect, and on the impact of our measurements on upcoming searches.
