description: How the bulk of the Universe's visible mass emerges and how it is manifest in the existence and properties of hadrons are profound questions that probe into the heart of strongly interacting matter. Paradoxically, the lightest pseudoscalar mesons appear to be the key to the further understanding of the emergent mass and structure mechanisms. These mesons, namely the pion and kaon, are the Nambu-Goldstone boson modes of QCD. Unravelling their partonic structure and the interplay between emergent and Higgs-boson mass mechanisms is a common goal of three interdependent approaches -- continuum QCD phenomenology, lattice-regularised QCD, and the global analysis of parton distributions -- linked to experimental measurements of hadron structure. Experimentally, the foreseen electron-ion collider will enable a revolution in our ability to study pion and kaon structure, accessed by scattering from the "meson cloud" of the proton through the Sullivan process. With the goal of enabling a suite of measurements that can address these questions, we examine key reactions to identify the critical detector system requirements needed to map tagged pion and kaon cross sections over a wide range of kinematics. The excellent prospects for extracting pion structure function and form factor data are shown, and similar prospects for kaon structure are discussed in the context of a worldwide programme. Successful completion of the programme outlined herein will deliver deep, far-reaching insights into the emergence of pions and kaons, their properties, and their role as QCD's Goldstone boson modes.

Gauged Supergravities in Various Spacetime Dimensions

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this review articel we study the gaugings of extended supergravity theories in various space-time dimensions. These theories describe the low-energy limit of non-trivial string compactifications. For each theory under consideration we review all possible gaugings that are compatible with supersymmetry. They are parameterized by the so-called embedding tensor which is a group theoretical object that has to satisfy certain representation constraints. This embedding tensor determines all couplings in the gauged theory that are necessary to preserve gauge invariance and supersymmetry. The concept of the embedding tensor and the general structure of the gauged supergravities are explained in detail. The methods are then applied to the half-maximal (N=4) supergravities in d=4 and d=5 and to the maximal supergravities in d=2 and d=7. Examples of particular gaugings are given. Whenever possible, the higher-dimensional origin of these theories is identified and it is shown how the compactification parameters like fluxes and torsion are contained in the embedding tensor.

description: In this paper we test if the $\sim$ 0.3 - 15 keV XMM-Newton EPIC pn spectral continuum of IPs can be described by the thermal Comptonization compTT model. We used publicly observations of 12 IPs (AE Aqr, EX Hya, V1025 Cen, V2731 Oph, RX J2133.7+5107, PQ Gem, NY Lup, V2400 Oph, IGR J00234+6141, IGR J17195-4100, V1223 Sgr, and XY Ari). We find that our modeling is capable to fit well the average spectral continuum of these sources. In this framework, UV/soft X-ray seed photons (with $$ of 0.096 $\pm$ 0.013 keV) coming presumably from the star surface are scattered off by electrons present in an optically thick plasma (with $$ of 3.05 $\pm$ 0.16 keV and optical depth $$ of 9.5 $\pm$ 0.6 for plane geometry) located nearby (on top) to the more central seed photon emission regions. A soft blackbody (bbody) component is observed in 5 out of the 13 observations analysed, with a mean temperature $$ of $0.095 \pm 0.004$ keV. We observed that the spectra of IPs show in general two photon indices $Γ$, which are driven by the source luminosity and optical depth. Low luminosity IPs show $$ of $1.83 \pm 0.19$, whereas high luminosity IPs show lower $$ of $1.34 \pm 0.02$. Moreover, the good spectral fits of PQ Gem and V2400 Oph indicate that the polar subclass of CVs may be successfully described by the thermal Comptonization as well.

description: We report the observation of the $A_{\rm g}$-symmetric one-magnon Raman peak in the magnon Bose-Einstein condensation phase of TlCuCl$_{3}$. Its Raman shift traces the one-magnon energy at the magnetic $Γ$ point, and its intensity is proportional to the squared transverse magnetization. The appearance of the one-magnon Raman scattering originates from the exchange magnon Raman process and reflects the change of the magnetic-state symmetry. Using the bond-operator representation, we theoretically clarify the Raman selection rules, being consistent with the experimental results.

description: We discuss several examples of non-toric quiver gauge theories dual to Sasaki-Einstein manifolds with U(1)^2 or U(1) isometry. We give a general method for constructing non-toric examples by adding relevant deformations to the toric case. For all examples, we are able to make a complete comparison between the prediction for R-charges based on geometry and on quantum field theory. We also give a general discussion of the spectrum of conformal dimensions for mesonic and baryonic operators for a generic quiver theory; in the toric case we make an explicit comparison between R-charges of mesons and baryons.

description: Neutron reaction data for the set of major chromium isotopes were reevaluated from the thermal energy range up to 20 MeV. In the low energy region, updates to the thermal values together with an improved $R$-matrix analysis of the resonance parameters characterizing the cluster of large $s$-wave resonances for $^{50,53}$Cr isotopes were performed. In the intermediate and high energy range up to 20 MeV, the evaluation methodology used statistical nuclear reaction models implemented in the EMPIRE code within the Hauser-Feshbach framework to evaluate the reaction cross sections and angular distributions. Exceptionally, experimental data were used to evaluate relevant cross sections above the resonance region up to 5 MeV in the major $^{52}$Cr isotope. Evaluations were benchmarked with Monte Carlo simulations of a small suite of critical assemblies highly sensitive to Chromium data, and with the Oktavian shielding benchmark to judge deep penetration performance with a 14-MeV D-T neutron source. A significant improvement in performance is demonstrated compared to existing evaluations.

description: We have used normal metal-insulator-superconductor tunnel junctions as thermometers at sub-Kelvin temperatures to study the electron-phonon (e-p) interaction in thin Aluminum films doped with Manganese, as a function of Manganese concentration. Mn in Al is known to be a Kondo impurity with extremely high Kondo temperature $T_K \sim$ 500 K, thus our results probe the e-p coupling in the fully spin compensated, unitary limit. The temperature dependence of the e-p interaction is consistent with the existing theory for disordered metals, however full theory including the Kondo effect has not been worked out yet. The strength of the interaction decreases with increasing Manganese concentration, providing a means to improve sensitivity of detectors and efficiency of solid state coolers.

description: We study the infrared conductivity of graphene at finite chemical potential and temperature taking into account the effect of phonons and disorder due to charged impurities and unitary scatterers. The screening of the long-range Coulomb potential is treated using the random phase approximation coupled to the coherent potential approximation. The effect of the electron-phonon coupling is studied in second-order perturbation theory. The theory has essentially one free parameter, namely, the number of charge impurities per carbon, n^{\rm C}_i. We find an anomalous enhancement of the conductivity in a frequency region that is blocked by Pauli exclusion and an impurity broadening of the conductivity threshold. We also find that phonons induce Stokes and anti-Stokes lines that produce an excess conductivity, when compared to the far infrared value of σ_0 = (π/2) e^2/h.

description: This study records and evaluates the dynamic interaction between the Metropolitan of Thessaloniki Gennadios Alexiadis and the jewish community of the city, during the crucial historical period 1912‐1951. Reclaiming primary ecclesiastical sources and research documentation of the findings of modern bibliography, the study reflects the impact of political events on the Jewish population of Thessaloniki and explores the reactions of the local Church and the personal contribution of Gennadios in shaping the terms and conditions of coexistence between Christians and Jews. Unlike the majority of the related studies, which are, at the same time, bounded and invested with meaning by the thematic pattern of the Holocaust, this research, with reference to acting and personality of Metropolitan Gennadios, is an ecclesiacentric study about the “co‐inherencestical” collusion of the religious communities of Thessaloniki, in the 20th century.
Semileptonic b to u transition

description: Experimental studies of charmless semileptonic B decays can be broadly categorized into inclusive and exclusive measurements depending on how the final states are treated. The inclusive method measures the decay rate $Γ(B \to X_u \ell ν)$, where $X_u$ is known as the hadronic system that does not contain charm-quark. On the other hand, the exclusive method measures the decay rates for exclusive final states such as $B \to π\ell ν$ and $ρ\ell ν$. Two methods give not only different efficiencies and signal-to-background ratios, but also different theoretical calculations to be used in order to extract $|V_{ub}|$. Using both approaches and comparing the results will help us verify the robustness of the theoretical error estimation, which dominates the current uncertainty in the determination of $|V_{ub}|$. Progress in last few years will be summarized in this presentation.

The music industry and Canadian national identity
Creators: name: Duffett, Mark
Publisher: name: University of British Columbia
Year: 2008

description: The links between national identity and the music industry in Canada are too diverse to be understood with any simplistic model of the nation. In early twentieth century Italy Ahtonio Gramsci examined the consumption of serialized stories written by foreigners. He developed a view of popular culture which focussed upon the role of the State in maintaining national unity. Since the federal State in Canada has intervened in the country's music business in recent years, Gramsci's schema provides us with a useful framework for that case. Moreover, his work avoids an orchestrated view of the nation or a narrow specification of the contents of culture. It allows us to take a view that Canadian culture is whatever Canadian's choose to write. Due to its inductive beginnings and theoretical shortcomings, the schema is not applied rigidly to music made by Canadians. Rather it has been kept on the sidelines to explore representations of Canadian music, the broadcasting, sound recording and concert promotion industries, and finally the future of music made in Canada. Gramsci's schema is one way to distinguish between the cause and uses of the nation in particular arguments. His ideas also explain why popular culture matters, without specifying its content or giving it artificial coherence. A framework is provided which admits that, in a society based upon exchange, the nation is fully implicated within a wider social fabric, so frequently cultural differences cannot be simplistically aligned with national borders. It allows us to reject essentialist nationalism and therefore the possibility of using the nation as a reason to suggest Canadian musicians are falling short, by not doing something different from their foreign counterparts. In its place the schema enables us to celebrate Canadian artists for what they have done in contributing to a wider sphere, and allows us to praise environments in which Canadian talent can be recognized and allowed to grow, whatever forms it takes.
Remarks on the Formulation of Quantum Mechanics on Noncommutative Phase Spaces

description: We consider the probabilistic description of nonrelativistic, spinless one-particle classical mechanics, and immerse the particle in a deformed noncommutative phase space in which position coordinates do not commute among themselves and also with canonically conjugate momenta. With a postulated normalized distribution function in the quantum domain, the square of the Dirac delta density distribution in the classical case is properly realised in noncommutative phase space and it serves as the quantum condition. With only these inputs, we pull out the entire formalisms of noncommutative quantum mechanics in phase space and in Hilbert space, and elegantly establish the link between classical and quantum formalisms and between Hilbert space and phase space formalisms of noncommutative quantum mechanics. Also, we show that the distribution function in this case possesses 'twisted' Galilean symmetry.

description: We analyse D-terms induced by gauge theory fluxes in the context of 6-dimensional supergravity models. On the one hand, this is arguably the simplest concrete setting in which the controversial idea of `D-term uplifts' can be investigated. On the other hand, it is a very plausible intermediate step on the way from a 10d string theory model to 4d phenomenology. Our specific results include the flux-induced one-loop correction to the scalar potential coming from charged hypermultiplets. Furthermore, we comment on the interplay of gauge theory fluxes and gaugino condensation in the present context, demonstrate explicitly how the D-term arises from the gauging of one of the compactification moduli, and briefly discuss further ingredients that may be required for the construction of a phenomenologically viable model. In particular, we show how the 6d dilaton and volume moduli can be simultaneously stabilized, in the spirit of KKLT, by the combination of an R symmetry twist, a gaugino condensate, and a flux-induced D-term.

On nonlinear free surface potential flow by a Bubnov-Galerkin formulation in space and a semi-lagrangian semi-implicit scheme in time
Creators: name: Allievi, Alejandro
Publisher: name: University of British Columbia
Year: 2012

description: The potential flow initial-boundary value problem describing fluid-structure interaction with fully nonlinear free surface boundary conditions has been studied using a mixed Lagrangian-Eulerian formulation. The boundary-value problem has been solved in the physical domain by means of a Bubnov-Galerkin formulation of the Laplace equation. The initialvalue problem related to the behavior of some of the moving boundaries has been discretized using various numerical techniques. Among these is a series of predictor-corrector methods. These methodologies proved to require considerable numerical smoothing to maintain stability of the numerical scheme. In turn, dissipation led to inaccuracies in the solution of the problem. In order to avoid this negative effect, a semi-implicit semi-Lagrangian two-time level iterative scheme that is almost free from smoothing has been developed. A Bubnov-Galerkin formulation of an elliptic system for the generation of boundary fitted curvilinear coordinates has been used. When solved iteratively, this method provides orthogonal meshes of very good characteristics for both symmetric and non-symmetric domains. Previous publications concluded that the present system was inadequate for non-symmetric regions leading to lack of convergence in the iterative process. Solutions described in this work show that this limitation has been overcome. Fluid responses to periodic excitation of surface-piercing and submerged bodies have been calculated. Both linear and nonlinear cases show agreement with published results. Very low total energy/work error has been obtained which demonstrates accuracy, good stability and convergence characteristics of the numerical scheme. The impulsive response of tanks of various shapes has also been simulated. Resulting natural frequencies show good agreement with available data. A slender body representation of the flow around a hull advancing with forward speed in otherwise calm water has also been simulated. Numerical calculations of a number of quantities of engineering interest are presented for different length Froude numbers. Results compare favorably with experimental data.

description: About half of the baryons in the local Universe are thought to reside in the so-called warm-hot intergalactic medium (WHIM) at temperatures of 0.1-10 million K. Thermal soft excess emission in the spectrum of some cluster outskirts that contains OVII and/or OVIII emission lines is regarded as evidence of the WHIM, although the origin of the lines is controversial due to strong Galactic and solar system foreground emission. We observed the Coma-11 field, where the most prominent thermal soft excess has ever been reported, with Suzaku XIS in order to make clear the origin of the excess. We did not confirm OVII or OVIII excess emission. The OVII and OVIII intensity in Coma-11 is more than 5 sigma below that reported before and we obtained 2 sigma upper limits of 2.8 and 2.9 photons cm^-2 s^-1 sr^-1 for OVII and OVIII, respectively. The intensities are consistent with those in another field (Coma-7) that we measured, and with other measurements in the Coma outskirts (Coma-7 and X Com fields with XMM-Newton). We did not confirm the spatial variation within Coma outskirts. The strong oxygen emission lines previously reported are likely due to solar wind charge exchange.

We trace this new effect to interacting charge neutral critical modes that emerge naturally from the two-band nature of the material. Li$_{0.9}$Mo$_6$O$_{17}$ is shown thereby to be a paradigm material that is capable of revealing new Luttinger physics.

Cross-fertilization of QCD and statistical physics: high energy scattering, reaction-diffusion, selective evolution, spin glasses and their connections

description: High energy scattering was recently shown to be similar to a reaction-diffusion process. The latter defines a wide universality class that also contains e.g. some specific population evolution models. The common point of all these models is that their respective dynamics are described by noisy traveling wave equations. This observation has led to a new understanding of QCD in the regime of high energies, and known universal results on reaction-diffusion models could be transposed to obtain quantitative properties of QCD amplitudes. Conversely, new general results for that kind of statistical models have also been derived. Furthermore, an intriguing relationship between noisy traveling wave equations and the theory of spin glasses was found.

description: Two different adsorption configurations of benzene on the Si(001)-(2x1) surface, the tight-bridge and butterfly structures, were studied using density functional theory. Several exchange and correlation functionals were used, including the recently developed vdW-DF functional, which accounts for the effect of van der Waals forces. In contrast to the PBE, revPBE and other GGA functionals, the vdW-DF functional finds that, for most coverages, the adsorption energy of the butterfly structure is greater than that of the tight-bridge structure.

These staus are produced in pairs by cosmic neutrino interactions in the Earth matter. We show that the background of stau events to the standard muon signal is negligible and plays no role in the determination of the cosmic neutrino flux. On the other hand, one can expect up to 50 pair events per year in a cubic kilometer detector such as IceCube, if the superpartner mass spectrum and the high-energy cosmic neutrino flux are close to experimental bounds.

Για την μοντελοποίηση των ρευμάτων θορύβου, που εγχέονται στο υπόστρωμα, χρησιμοποιείται μια προσομοίωση σε επίπεδο πύλης, προσφέροντας πολύ γρήγορα αποτελέσματα. Τα ίδια μοντέλα που χρησιμοποιήθηκαν για την προσομοίωση του θορύβου υποστρώματος, χρησιμοποιούνται και για την προσομοίωση της διακύμανσης στην τάση τροφοδοσίας. Κατά την εκκίνηση την ψηφιακού κυκλώματος, προσομοιώνεται η μεταβολή στην πτώση τάσης στην τροφοδοσία ως προς τον αριθμό των πυλών, τα παρασιτικά της συσκευασίας και του PCB και χωρητικότητες αποσύζευξης. Τέλος, προτείνονται τεχνικές για την ελαχιστοποίηση της πτώσης τάσης.
description: A novel substrate coupling modeling and analysis flow for CMOS system on chip design is presented. The proposed methodology provides a full chip level simulation including substrate, interconnect parasitics and package in any stage of the design process. Because of the exclusive use of commercial design tools, this method can be directly adopted by designers and integrated into the industry design flow. A 5 GHz CMOS LNA in the presence of an 88 kGates digital logic, is used as a crosstalk test vehicle (noise victim) to validate the proposed methodology. A custom gate level simulator is used to model on the fly the switching noise currents injected into the substrate. The modelling entities of the substrate crosstalk simulation flow, are also used in a voltage drop simulation flow. Voltage drop was simulated from low to large logic designs during the startup of the logics and the respective tradeoffs versus the gate number, the package and PCB parasitics and the decoupling and MIM Capacitors usage were simulated. Guidelines o minimization techniques were also provided.

description: Σήμερα, ο επιχειρηματικός κόσμος έχει γίνει ανταγωνιστικός, οπότε είναι αρκετά σημαντικό για μια εταιρεια να αποκτήσει ανταγωνιστικό πλεονέκτημα έναντι των ανταγωνιστών της. Οι υπεύθυνοι λήψης αποφάσεων σε μία εταιρεία πρέπει να έχουν πρόσβαση σε υποστηρικτικά εργαλεία λήψης αποφάσεων για να παίρνουν γρήγορες, σωστές και ακριβείς αποφάσεις. Ένας από αυτούς τους κλάδους είναι και η επιλογή παρόχου υπηρεσιών logistics. Η επιλογή παρόχου υπηρεσιών logistics είναι μια πολυκριτήρια διαδικασία λήψης απόφασης που ασχολείται με τη βελτιστοποιήση αντικρουόμενων στόχων όπως το κόστος, η ποιότητα και ο χρόνος παράδοσης. Εάν η διαδικασία αυτή δεν υποστηρίζεται από ένα σύστημα, θα είναι πολύπλοκη και χρονοβόρα. Σε αυτή τη διατριβή, παρουσιάζεται ένα υποστηρικτικό σύστημα λήψης απόφασης για την επιλογή του καλύτερου παρόχου υπηρεσιών logistics, βασισμένο στην Αναλυτική Ιεραρχική Διαδικασία που έχει ευρέως χρησιμοποιηθεί για πολυκριτήρια προβλήματα λήψης αποφάσεων. Δεδομένου ότι οι fuzzy αντιλήψεις και η χρησιμοποίηση εμπειρικών δεδομένων επεκτείνουν την ικανότητα κάθε ερευνητικού μοντέλου, ενσωματώνοντας τα μες το μοντέλο θα μας οδηγήσουν σε ένα πιο δυναμικό σύστημα. Για να επιβεβαιώσουμε την επιλογή της fuzzy Αναλυτικής Ιεραρχικής Διαδικασίας και επίσης για να επικυρώσουμε τον εννοιολογικό σχεδιασμό του συστήματος λήψης απόφασης για την επιλογή του παρόχου υπηρεσιών logistics, διεξήχθη μία μελέτη περίπτωσης στην εταιρεία "ΜΑΤΖΑΡΙΔΗΣ ΑΦΟΙ Α.Β.Ε.Τ.Ε.".
description: Nowadays, the business world has become competitive so it is immensely important for a company to gain a competitive advantage against its competitors. Decision makers of a firm need to have access to decision support tools so as to make quick, right and accurate decisions. One of these decision making areas is logistics service provider selection. Logistics service provider selection is a multi – criteria decision making process that deals with the optimization of conflicting objectives such as cost, quality and delivery time. If it is not supported by a system, this would be a complex and time consuming process. In this thesis, logistics service provider selection decision support system based on the analytic hierarchy process (AHP) method which has been commonly used for multi – criteria decision making problems is proposed. Insofar as it is believed that fuzzy concepts and usage of empirical data extend the capability of any modeling approach, integrating them into model will lead to a more powerful system. To validate choice of the Fuzzy AHP model and also to validate the conceptual design of logistics service provider selection decision support system, it is conducted a case study in "MAJARIDIS BROS S.A.".

description: Το θέμα της παρούσας μεταπτυχιακής εργασίας αφορά ουσιαστικά στην εξέλιξη της ιστορίας της Θεσσαλονίκης κατά το τελευταίο τέταρτο του 19ου και τις αρχές του 20ου αιώνα και στο ρόλο που έπαιξε η Εκκλησία μέσα από το έργο της μητρόπολης Θεσσαλονίκης, όπως προβάλλεται στον Τύπο της πόλης. Η Θεσσαλονίκη την περίοδο αυτή είναι μια πόλη που διακρίνεται για τη σύνθετη πληθυσμιακή δομή της αλλά και την έντονη κοινωνική και πνευματική της ζωή. Η τοπική Εκκλησία έχοντας αναλάβει στην πράξη το ρόλο του ηγέτη της χριστιανικής κοινότητας της πόλης επιδεικνύει πλούσιο διοικητικό, ποιμαντικό, κοινωνικό-φιλανθρωπικό και εκπαιδευτικό έργο. Ο μητροπολίτης Θεσσαλονίκης αναδεικνύεται σε τοπικό ηγέτη, ενώ ο Τύπος προβάλλει το έργο του με ιδιαίτερο ενδιαφέρον και επιτρέπει τη μελέτη του συνόλου της ιστορικής και κοινωνικής εξέλιξης της πόλης την περίοδο αυτή.
description: The present study concentrates on the social evolution and the historical process that the city of Thessaloniki developed during the last quarter of the nineteenth and the beginning of the twentieth centuries and the part that the local Church played in this process as it is indicated by the local Press’s work. The city of Thessaloniki of this period is distinguished for its compound populational structure but also for its intense social and spiritual life as a whole. The local Church had taken the lead part of the Christian community of the city and leads the important administrational, social and educational work that is been made in the city. The Bishop of Thessaloniki is actually the local leader of the community while at the same time the local Press shows with great interest his work and allows the study of the historical and social evolution of the city.

description: The instantaneous transition rate of an arbitrarily accelerated Unruh-DeWitt particle detector on four-dimensional Minkowski space is ill defined without regularisation. We show that Schlicht's regularisation as the zero-size limit of a Lorentz-function spatial profile yields a manifestly well-defined transition rate with physically reasonable asymptotic properties. In the special case of stationary trajectories, including uniform acceleration, we recover the results that have been previously obtained by a regularisation that relies on the stationarity. Finally, we discuss evidence for the conjecture that the zero-size limit of the transition rate is independent of the detector profile.

description: We consider static non-extremal charged black hole solutions in the context of N=2 gauged supergravity theories in five dimensions, and we show that they satisfy first-order flow equations. Then we analyze the motion of the dual brane in these black hole backgrounds. We express the entropy in terms of a Cardy-Verlinde-type formula, and we show that the equations describing the FRW cosmology on the brane have a form that is similar to the equations for the entropy and for the Casimir energy on the brane. We also briefly comment on the inclusion of a Gauss-Bonnet term in the analysis.

Photodynamic therapy of squamous cell carcinoma : an evaluation of a new photosensitizing agent and photoimmunoconjugate
Creators: name: Hemming, Alan William
Publisher: name: University of British Columbia
Year: 2008

description: Photodynamic therapy for cancer depends on the relatively selective distribution of photosensitizing agents to malignant as compared to normal tissues, rendering the malignant cells more susceptable to light mediated damage. Photodynamic therapy has been used with only moderate success to date. The purpose of this study was to compare a new photosensitizing agent, Benzoporphyrin derivative (BPD), to the standard agent presently in use, Photofrin II, in a hamster cheek pouch model of squamous cell carcinoma. As well we have investigated the potential of using a tumor specific monoclonal antibody - BPD conjugate to improve the tumor localizing properties of BPD. Treatment consisted of photodynamic therapy with either Photofrin II, BPD, or a tumor specific antiepidermal growth factor receptor -BPD conjugate. Control groups of light alone, antiEGFr, tumor non-specific antiCEA, and tumor nonspecific antiCEA-BPD conjugate were included with the contralateral cheek pouch of each animal acting as a dark control. An assessment of differential delivery of BPD to tumor and to normal mucosa was undertaken using a spectrophotometric assay. Parametric statistical analysis included student "t" tests and linear regression while non-parametric analysis was undertaken using Fisher's exact test. Animals receiving BPD alone demonstrated tumor to tissue levels of approximately 2:1 while animals receiving the tumor specific antiEGFr-BPD conjugate had significantly better tumor:tissue ratios of 26:1. (p < 0.005) Animals treated with Photofrin II had a one month cancer free survival of 27% while animals treated with BPD had an improved survival of 67% (p =0.03) The group treated with the tumor specific antiEGFr-BPD conjugate at a twentieth the total dose of BPD had an 80% one month cancer free survival which was not statistically different from the group treated with BPD alone. Benzoporphyrin appears to be a more effective photosensitizing agent than Photofrin II and its tumor selectivity can be improved using a tumor specific monoclonal antibody conjugate.

description: We study the conductivity in itinerant-electron systems near to a magnetic quantum critical point. We show that, for a class of geometries, the universal power-law dependence of resistivity upon temperature may be reflected in a universal non-linear conductivity; when a strong electric field is applied, the resulting current has a universal power-law dependence upon the applied electric field. For a system with thermal equilibrium current proportional to $T^α$ and dynamical exponent $z$, we find a non-linear resistivity proportional to $E^{\frac{z-1}{z(1+α)-1}}$.

Το υπόβαθρο της περιοχής συνίσταται από τα κρυσταλλοσχιστώδη πετρώματα της Ενότητας Παγγαίου, τα οποία καλύπτονται ασύμφωνα από Νεογενείς και Τεταρτογενείς αποθέσεις. Η ρηξιγενής ζώνη των Σερρών ευθύνεται για τη δημιουργία του σημερινού μορφολογικού ανάγλυφου της περιοχής και θεωρείται σήμερα ενεργή. Στα πρανή της ζώνης εφαρμόστηκε μία ποικιλία μορφοτεκτονικών αναλύσεων, με σκοπό τον ποσοτικό καθορισμό μορφοτεκτονικών δεικτών. Για το σκοπό αυτό, χρησιμοποιήθηκε ένα ψηφιακό μοντέλο εδάφους το οποίο κατασκευάστηκε από την επεξεργασία δορυφορικών δεδομένων ASTER.
description: In this paper we present the results of the study Morphotectonics slopes of the north rift margin of the Serres basin. The geological background of the area consisting of the crystalline rocks of Pangeo Unity, covered unconformably by Neogene and Quaternary deposits. The Serres fault zone is responsible for the creation of the current morphological terrain of the area and is considered active. In the fault scarps of the zone a variety morphotectonic analysis was applied, in order to quantify morphotectonic indicators. For this purpose, we used a digital terrain model, which was manufactured by processing satellite ASTER data.
Measuring the Solar Wind Angular Momentum Flux and Examining its Astrophysical Implications

description: The rate at which the solar wind extracts angular momentum from the Sun has been predicted by theoretical models for many decades, and yet we lack a conclusive measurement from in-situ spacecraft. Complementary information can be gained by studying other Sun-like stars, as it is known that the rotation rates of Sun-like stars follow a tight relationship with age. This allows us to evaluate their angular momentum-loss rates, without any knowledge of stellar wind physics, and produce an independent prediction of the current solar angular momentum-loss rate to compare with numerical models and in-situ observations of the solar wind. I will discuss recent measurements of the solar wind angular momentum flux from Parker Solar Probe, in context with previous observations and model predictions. I aim to show that by better understanding the current solar angular momentum-loss rate we can further constrain rotation-evolution models of low-mass stars, which will subsequently influence how magnetic activity evolves during the late main sequence. It is thought that in future, a combination of observations from Parker Solar Probe and Solar Orbiter may lead to a better evaluation the solar wind angular momentum-loss rate.
