description: Breastfeeding offers so many benefits for families, including: • The joyful bonding with your baby • The perfect nutrition only you can provide • The cost savings • The health benefits for both mother and baby Even so, African American women are much less likely to breastfeed than other women. What was once an important tradition is not the norm for raising children today. There are many reasons for this trend, starting with a lack of support. There isn’t enough helpful breastfeeding information for African American women. Plus, from hospitals to drugstores, the message is “feed your baby formula.” When we look to our …

description: Parity solutions to the strong CP problem are a compelling alternative to approaches based on Peccei-Quinn symmetry, particularly given the expected violation of global symmetries in a theory of quantum gravity. The most natural of these solutions break parity at a low scale, giving rise to a host of experimentally accessible signals. We assess the status of the simplest parity-based solution in light of LHC data and flavor constraints, highlighting the prospects for near-future tests at colliders, tabletop experiments, and gravitational wave observatories. The origin of parity breaking and associated gravitational effects play crucial roles, providing new avenues for discovery through EDMs and gravity waves. These experimental opportunities underline the promise of generalized parity, rather than Peccei-Quinn symmetry, as a robust and testable solution to the strong CP problem.

description: We report on a comprehensive investigation of the effects of strain and film thickness on the structural and magnetic properties of epitaxial thin films of the prototypal $J_\mathrm{eff}=1/2$ compound Sr$_2$IrO$_4$ by advanced X-ray scattering. We find that the Sr$_2$IrO$_4$ thin films can be grown fully strained up to a thickness of 108 nm. By using X-ray resonant scattering, we show that the out-of-plane magnetic correlation length is strongly dependent on the thin film thickness, but independent of the strain state of the thin films. This can be used as a finely tuned dial to adjust the out-of-plane magnetic correlation length and transform the magnetic anisotropy from two-dimensional (2D) to three-dimensional (3D) behavior by incrementing film thickness. These results provide a clearer picture for the systematic control of the magnetic degrees of freedom in epitaxial thin films of Sr$_2$IrO$_4$ and bring to light the potential for a rich playground to explore the physics of $5d$-transition metal compounds.

Pseudorotational energy spectrum of an octahedral molecule with 1/2-integer spin
Creators: name: Douglas, Jessica Lynn Rogers
Publisher: name: University of British Columbia
Year: 2009

description: The Jahn-Teller effect, which underlies non-linear molecular energy spectra, has been the focus of many studies and measurements since its discovery in the 1930's. In this work we theoretically calculate the pseudorotational energy spectrum of an octahedral molecule using a two parameter fit. In particular we calculate the doubly degenerate energy levels belonging to the Fg (e©£2g) problem. The Born-Oppenheimer Hamiltonian is constructed and solved on the canonical line bundle over HP(l). According to the strong Jahn-Teller approximation, the non-Jahn-Teller active vibrations are built upon the solutions to the Born-Oppenheimer Hamiltonian. This complete spectrum is compared to spectral data taken using IrFg.

The design and development of a phantom for use in dynamic spect imaging
Creators: name: Farncombe, Troy
Publisher: name: University of British Columbia
Year: 2009

description: It has been suggested that the rate of tracer extraction from certain organs reflects the functional ability of that organ. The determination of the kinetic rates associated with extraction could therefore potentially provide a useful measure of organ function and could help in the diagnosis of disease. Dynamic SPECT is one imaging modality that attempts to determine these kinetic rates in three dimensions. A dynamic heart-in-thorax phantom has been developed for testing dynamic SPECT reconstruction methods. This phantom consists of a plastic myocardial volume containing smaller "defect" volumes, and a central blood pool. Surrounding the heart phantom is a larger thorax phantom which provides a non-uniform attenuating medium. The heart volumes are loaded with activity and washed out with water, thus producing the same type of activity decay that is seen to occur in the metabolism of fatty acids in the myocardium. By varying the flow rate of water into the phantom, different washout times can be obtained. Additionally, the phantom can be used in a variety of applications including multiple exponential decay and the investigation of input functions. Testing of the phantom using both planar dynamic and image based SPECT protocols show that the phantom accurately reproduces preset washout rates to within 10%. With this level of accuracy attained, we feel the phantom can confidently be used in the development of new dynamic SPECT reconstruction algorithms.

description: We present preliminary results of an interferometric study of the water megamaser in the merger system Arp299. This system is composed of two main sources: IC694 and NGC3690. There is clear evidence that most of the water maser emission is associated with the nucleus of the latter, confirming the presence of an optically obscured AGN as previously suggested by X-ray observations. Furthermore, emission arises from the inner regions of IC694, where an OH megamaser is also present. The velocity of the water maser line is blueshifted w.r.t. the optically determined systemic velocity and is consistent with that of the OH megamaser line. This finding might then indicate that both masers are associated with the same (expanding) structure and that, for the first time, strong 22 GHz water and 1.67 GHz OH maser emission has been found to coexist.

description: The model of low-energy quantum gravity by the author has the property of asymptotic freedom at very short distances. The character of transition to asymptotic freedom is studied here. It is shown that this transition is not universal, but the one obeys the scaling rule: the range of this transition in units of $r/E^{1/2}$, where $r$ is a distance between particles and $E$ is an energy of the screening particle, is the same for any micro-particle. This range for a proton is between $10^{-11} - 10^{-13}$ meter, while for an electron it is approximately between $10^{-13} - 10^{-15}$ meter.

description: We have studied in fields up to 60T the variation of the transverse magnetoresistance (MR) of underdoped YBCO6.6 crystals either pure or with Tc reduced down to 3.5K by electron irradiation. We evidence that the normal state MR is restored above a threshold field H'c(T), which is found to vanish at T'c>>Tc. In the pure YBCO6.6 sample a 50 Tesla field is already required to completely suppress the superconducting fluctuations at Tc. While disorder does not depress the pseudogap temperature, it reduces drastically the phase coherence established at Tc and weakly H'c(0), T'c and the onset Tnu of the Nernst signal which are more characteristic of the 2D local pairing.

description: The aim of this master thesis is to provide a literature-based overview of the basic approaches to translator teaching worldwide -which is not intended as an exhaustive review of all didactic literature in translation studies though, but as a review of major findings and studies in this field. For this purpose, owing to the wide-ranging literature on this topic, the basic approaches have been categorized and the main representatives of each trend have been presented, in an effort to show the diversity of views that have been expressed in this field -and which are not necessarily mutually exclusive.The examination of the literature on translator training indicates that translation teaching is -or should be- based on five basic approaches, namely the Model for Translation-oriented Text Analysis, the Process-oriented approaches, the Task-based approaches, the Socioconstructive approach and the use of Corpora in Translation Training.

description: We attempt to address the old problem of plane shear flows: the origin of turbulence and hence transport of angular momentum in accretion flows as well as laboratory flows, such as plane Couette flow. We undertake the problem by introducing an extra force in Orr-Sommerfeld and Squire equations along with the Coriolis force mimicking the local region of the accretion disk. For plane Couette flow, the Coriolis term drops. Subsequently we solve the equations by WKB approximation method. We investigate the dispersion relation for the Keplerian flow and plane Couette flow for all possible combinations of wave vectors. Due to the very presence of extra force, we show that both the flows are unstable for a certain range of wave vectors. However, the nature of instability between the flows is different. We also study the Argand diagrams of the perturbation eigenmodes. It helps us to compare the different time scales corresponding to the perturbations as well as accretion. We ultimately conclude with this formalism that fluid gets enough time to be unstable and hence plausibly turbulent particularly in the local regime of the Keplerian accretion disks. Repetition of the analysis throughout the disk explains the transport of angular momentum and matter along outward and inward direction respectively.

description: Multidimensional torus interconnect finds wide application in modern exascale computing. For models design in high-performance computing, grid and cloud computing, and also systems biology, two basic ways of specifying spatial structures with Petri nets are considered – an infinite Petri net specified by a parametric expression (PE) and a reenterable coloured Petri net (CPN). The paper studies a composition of hypertorus grid models in the form of a PE and a reenterable CPN, their mutual transformations, and unfolding into a place/transition net; the parameters are the number of dimensions and the size of grid. A grid is composed via connection of neighbouring cells by dedicated transitions modelling channels. Reenterable model peculiarities are explained on step-by-step simulation examples. The rules of mutual transformations of Petri net spatial specifications are specified. Comparative investigation of two mentioned forms of spatial specifications is implemented, including analysis techniques and tools. CPNs are convenient for the state space analysis. The main advantage of PEs is the ability to obtain linear invariants and other structural constructs of Petri nets, for instance, siphons and traps, in parametric form that allows us to draw conclusions on Petri net properties for any values of parameters.

description: The formalism for uniform description of Drell-Yan transverse-momentum spectrum is presented in a framework of High-Energy Factorization, which smoothly interpolates between Collins-Soper-Sterman formalism at $|{\bf q}_T|\ll Q$ and usual Collinear Parton Model at $|{\bf q}_T|\sim Q\ll \sqrt{S}$. The new formula for deriving Unintegrated Parton Distribution Functions(UPDFs) from collinear ones is introduced, which leads to excellent description of the shape of $Z$-boson $|{\bf q}_T|$-spectrum at high energies up to $|{\bf q}_T|/\sqrt{S}\simeq 0.02$. Description of normalized $|{\bf q}_T|$-distributions at low energies is achieved via the fit of non-perturbative parameters of quark UPDFs. Reasonable description of angular distributions of leptons in the dilepton center-of-mass frame is also obtained with new UPDFs.

description: Quantitative photoacoustic tomography aims to recover the spatial distribution of absolute chromophore concentrations and their ratios from deep tissue, high-resolution images. In this study, a model-based inversion scheme based on a Monte-Carlo light transport model is experimentally validated on 3-D multispectral images of a tissue phantom acquired using an all-optical scanner with a planar detection geometry. A calibrated absorber allowed scaling of the measured data during the inversion, while an acoustic correction method was employed to compensate the effects of limited view detection. Chromophore- and fluence-dependent step sizes and Adam optimization were implemented to achieve rapid convergence. High resolution 3-D maps of absolute concentrations and their ratios were recovered with high accuracy. Potential applications of this method include quantitative functional and molecular photoacoustic tomography of deep tissue in preclinical and clinical studies.
Error estimates for the Scaled Boundary Finite Element Method

description: The Scaled Boundary Finite Element Method (SBFEM) is a technique in which approximation spaces are constructed using a semi-analytical approach. They are based on partitions of the computational domain by polygonal/polyhedral subregions, where the shape functions approximate local Dirichlet problems with piecewise polynomial trace data. Using this operator adaptation approach, and by imposing a starlike scaling requirement on the subregions, the representation of local SBFEM shape functions in radial and surface directions are obtained from eigenvalues and eigenfunctions of an ODE system, whose coefficients are determined by the element geometry and the trace polynomial spaces. The aim of this paper is to derive a priori error estimates for SBFEM's solutions of harmonic test problems. For that, the SBFEM spaces are characterized in the context of Duffy's approximations for which a gradient-orthogonality constraint is imposed. As a consequence, the scaled boundary functions are gradient-orthogonal to any function in Duffy's spaces vanishing at the mesh skeleton, a mimetic version of a well-known property valid for harmonic functions. This orthogonality property is applied to provide a priori SBFEM error estimates in terms of known finite element interpolant errors of the exact solution. Similarities with virtual harmonic approximations are also explored for the understanding of SBFEM convergence properties. Numerical experiments with 2D and 3D polytopal meshes confirm optimal SBFEM convergence rates for two test problems with smooth solutions. Attention is also paid to the approximation of a point singular solution by using SBFEM close to the singularity and finite element approximations elsewhere, revealing optimal accuracy rates of standard regular contexts.

description: Η καλλιέργεια του θρησκευτικού συναισθήματος είναι ένα από τα απαραίτητα στοιχεία της αγωγής. Η ορθόδοξη χριστιανική αγωγή παρέχεται όχι μόνο λόγω του ελληνορθόδοξου χαρακτήρα της πολιτιστικής μας παράδοσης αλλά και λόγω της κατοχύρωσης των σχετικών άρθρων του Συντάγματος. Η ηλικία των 6-12 χρόνων είναι η πιο κατάλληλη για ηθικοθρησκευτική αγωγή. Σημαντικοί φορείς αγωγής είναι οι γονείς και οι δάσκαλοι που επιδρούν και σαν πρότυπα μίμησης στο παιδί. Απαραίτητη είναι συνεργασία γονέων-δασκάλων για την επίτευξη των στόχων της αγωγής γενικά και της θρησκευτικής ειδικότερα. Εξαιρετικά σπουδαίος είναι ο ελεύθερος χρόνος για το παιδί και η στέρησή του έχει συνέπειες στην ψυχοσωματική του υγεία. Ο ελεύθερος χρόνος πρέπει ευκαιρίες αληθινής ψυχαγωγίας
description: The culture of religious sentiment is one of the essential elements of education. The orthodoxe christian education is provided not only because of the greek orthodoxe character of our cultural delivery but also because of the consolidation of relative articles of Constitution. The age of 6-12 years most suitable for moral and religious education. Important institutions of education are the parents and the schoolteachers that affect also as models of imitation in the child. The collaboration of parents and schoolteachers is essential for the achievement of objectives of education generally and religious more specifically. Exceptionally important is the free time for the child and its deprival has consequences in his health. The free time should give opportunities of genuine entertainment

description: We propose a new model for treating solid-phase photoprocesses in interstellar ice analogues. In this approach, photoionization and photoexcitation are included in more detail, and the production of electronically-excited (suprathermal) species is explicitly considered. In addition, we have included non-thermal, non-diffusive chemistry to account for the low-temperature characteristic of cold cores. As an initial test of our method, we have simulated two previous experimental studies involving the UV irradiation of pure solid O$_2$. In contrast to previous solid-state astrochemical model calculations which have used gas-phase photoabsorption cross-sections, we have employed solid-state cross-sections in our calculations. This method allows the model to be tested using well-constrained experiments rather than poorly constrained gas-phase abundances in ISM regions. Our results indicate that inclusion of non-thermal reactions and suprathermal species allows for reproduction of low-temperature solid-phase photoprocessing that simulate interstellar ices within cold ($\sim$ 10 K) dense cores such as TMC-1.

description: High resolution imaging of inner jets in Active Galactic Nuclei (AGNs) with VLBI at millimeter wavelengths provides deep insight into the launching and collimation mechanisms of relativistic jets. The BL Lac object, PKS 1749+096, shows a core-dominated jet pointing toward the northeast on parsec-scales revealed by various VLBI observations. In order to investigate the jet kinematics, in particular, the orientation of the inner jet on the smallest accessible scales and the basic physical conditions of the core, in this work we adopted a super-resolution technique, the Bi-Spectrum Maximum Entropy Method (BSMEM), to reanalyze VLBI images based on the Very Long Baseline Array (VLBA) observations of PKS 1749+096 within the VLBA-BU-BLAZAR 7 mm monitoring program. These observations include a total of 105 epochs covering the period from 2009 to 2019. We found that the stacked image of the inner jet is limb-brightened with an apparent opening angle of 50°.0 +/- 8°.0 and 42°.0 +/- 6°.0 at the distance of 0.2 and 0.3 mas (0.9 and 1.4 pc) from the core, corresponding to an intrinsic jet opening angle of 5°.2 +/- 1°.0 and 4°.3 +/- 0°.7, respectively. In addition, our images show a clear jet position angle swing in PKS 1749+096 within the last ten years. We discuss the possible implications of jet limb brightening and the connection of the position angle with jet peak flux density and gamma-ray brightness.

description: Large-scale calculations of atomic structures and radiative properties have been carried out for singly, doubly- and trebly ionized cerium. For this purpose, the purely relativistic multiconfiguration Dirac-Hartree-Fock (MCDHF) method was used, taking into account the effects of valence-valence and core-valence electronic correlations in detail. The results obtained were then used to calculate the expansion opacities characterizing the kilonovae observed as a result of neutron star mergers. Comparisons with previously published experimental and theoretical studies have shown that the results presented in this work are the most complete currently available, in terms of quantity and quality, concerning the atomic data and monochromatic opacities for Ce II, Ce III and Ce IV ions.

description: The prospects for central exclusive diffractive (CED) production of MSSM Higgs bosons at the LHC are reviewed. It is shown that the CED channels, making use of forward proton detectors at the LHC installed at 220 m and 420 m distance around ATLAS and / or CMS, can provide important information on the Higgs sector of the MSSM. In particular, CED production of the neutral CP-even Higgs bosons h and H and their decays into bottom quarks has the potential to probe interesting regions of the M_A--tan_beta parameter plane of the MSSM and may give access to the bottom Yukawa couplings of the Higgs bosons up to masses of M_H \approx 250 GeV.

description: Η δωρεά οργάνων θεωρείται ως μία πράξη αλτρουισμού και κοινωνικής προσφοράς. Ένα μεγάλο εύρος ζητημάτων που σχετίζονται με σειρά ηθικών και φιλοσοφικών διλημμάτων, σχετίζονται με τον ορισμό των πτωματικών δοτών, τη ρητή και την εικαζόμενη συναίνεση, την εμπλοκή της οικογένειάς τους στις διαδικασίες της μεταμόσχευσης και τον ορισμό της ώρας του θανάτου, εγκεφαλικού ή καρδιαγγειακού. Όλα τα ανωτέρω έχουν απασχολήσει ιατρούς, νομικούς και θεολόγους, από άποψη ηθικής. Πρόσθετα ηθικά διλήμματα σχετίζονται με τους ζώντες δότες, όπως η ασφάλεια της υγείας τους, τα κίνητρα της δωρεάς και την πληροφόρηση που πρέπει να λάβουν σχετικά με τις πιθανές αρνητικές συνέπειες της μεταμόσχευσης. Μερικά από τα παραπάνω ηθικά διλήμματα έχουν ρυθμιστεί σε θεσμικό πλαίσιο στοχεύοντας στην αναβάθμιση της οικογενειακής συμμετοχής (συναίνεση) στην αφαίρεση των οργάνων. Η διπλωματική εργασία έχει ως σκοπό να συνεισφέρει στο διάλογο περί εγκεφαλικού θανάτου και να παρουσιάσει μία, κατά το δυνατό, πλήρη και ισορροπημένη προσέγγιση. Ο εγκεφαλικός θάνατος, η εικαζόμενη συναίνεση και οι επιμέρους ηθικές, φιλοσοφικές, ιατρικές, νομικές και θεολογικές τους πτυχές θα αναπτυχθούν στη βάση μίας βιβλιογραφικής επισκόπησης δευτερογενών πηγών, συμπεριλαμβανομένης της κριτικής σκοπιάς της συγγραφέως.
description: Organ donation is considered as an act of altruism and social offer. A wide range of issues that have to do with ethical and philosophical dilemmas related, specially, to the definition of deceased donors, the explicit and the presumed consent, the consent of their family in the transplantation proceedings and the time of death (cerebral or cardiac). All of those above have preoccupied physicians, lawyers and theologists in terms of ethics. Additional ethical dilemmas are also associated with living donors, their safety, the donation incentives, and the special information they have to be received about the potential negative effects of a donation by transplant. Some of these dilemmas have been regulated by the institutional framework, aiming at the upgrade of the family involvement (consent) in organ removal The essay is aiming at participating throughout the dialogue about cerebral death by introducing, as possible as it gets, an integrated and balanced approach. Cerebral death, presumed consent as well as their further moral, philosophical, medical, legalistic and theological aspects is about to be presented through a literature review, including author’s critical view.

description: Στην εργασία αυτή παρουσιάζετε μία αξιολόγηση της επίδρασης των θερμοκρασιακών μεταβολών στην στρατόσφαιρα στη σχετική διαφορά επίγειων και δορυφορικών μετρήσεων όζοντος.Για τον σκοπό αυτό χρησιμοποιήθηκαν δορυφορικές και επίγειες παρατηρήσεις της ολικής στήλης του όζοντος από το δορυφορικό όργανο Global Ozone Monitoring Experiment-GOME στον ERS-2 και από φασματοφωτόμετρα Brewer και Dobson αντίστοιχα. Επίσης παρουσιάζονται αναλυτικά οι αλγόριθμοι που χρησιμοποιεί το κάθε όργανο, και το πώς αυτοί επηρεάζονται από παράγοντες όπως η εποχικότητα. Εξετάστηκαν 28 επίγειοι σταθμοί στο βόρειο ημισφαίριο, εκ των οποίων οι 14 διέθεταν φασματοφωτόμετρα Dobson και οι υπόλοιποι 14 φασματοφωτόμετρα Brewer. Για το νότιο ημισφαίριο εξετάστηκαν 4 σταθμοί οι οποίοι διέθεταν αποκλειστικά φασματοφωτόμετρα Dobson. Για τους σταθμούς που υπήρχαν και οι δύο τύποι φασματοφωτομέτρων εξετάστηκε συγκριτικά η ευαισθησία του κάθε οργάνου στις μεταβολές της στρατοσφαιρικής θερμοκρασίας. Η επιλογή του συνόλου των σταθμών έγινε έτσι ώστε να έχουμε τουλάχιστον έναν σταθμό ανά 10o γεωγραφικού πλάτους για πλάτη από 0ο-80ο στο βόρειο ημισφαίριο και για πλάτη από 0ο-60ο στο νότιο ημισφαίριο.
description: Accurate global ozone records from passive remote sensing and ground based observations play a vital role in ozone trend analysis and climate change studies.The capability of atmospheric chemistry instruments as GOME, Brewer and Dobson to investigate ozone columns demonstrates seasonal and temperature dependency. In order to investigate the impact of temperature deviation in stratosphere, satellite and ground based measurements were obtained from GOME, Brewer and Dobson instruments, during the years 1997 to 2004. The instrumentation, algorithms and data analysis methods were thoroughly analyzed in this thesis. Data from 28 stations in the northern hemisphere were examined from which 14 hosted Brewer spectrophotometer and 14 Dobson spectrophotometer. Data from Dobson spectrophotometers for 4stations of the southern hemisphere were also examined. For the stations hosting both types of spectrophotometers we studied the sensitivity of each instrument to stratospheric temperature variations comparatively. The total of the 33 stations was selected so as to have at least one ground instrument per 10o for latitudes from 0o to 80o in the northern hemisphere and latitudes from 0o to 60o in the southern hemisphere.
