description: Johanniskrautextrakte (Hypericum perforatum) werden vor allem zur Behandlung milder bis moderater Depressionen eingesetzt. Die chemische Zusammensetzung der Extrakte unterliegt jedoch immensen Schwankungen, abhängig vom Genotyp sowie biotischen und abiotischen Umweltfaktoren. In dieser Arbeit wurde die intraspezifische Varianz der Metabolitenprofile von H. perforatum und die interspezifische Varianz der Gattung Hypericum untersucht. Durch die Kombination analytischer Methoden (TLC, NMR, NMR Pure Shift, LC-HRMS) wurden die Sekundärmetaboliten ungerichtet detektiert und chemometrisch ausgewertet. Mit Hilfe umfassender Metabolomics-Studien von 93 H. perforatum Genotypen aus Nordamerika und Europa und 21 verschiedener Hypericum-Arten konnten wirksamkeitsrelevante Schwankungen der Metabolitenzusammensetzung festgestellt werden. Des Weiteren wurden mittels Korrelationsanalysen Aspekte der Hypericin-Biosynthese beleuchtet, sowie potentiell antibakterielle Inhaltstoffe identifiziert.
description: St. John's wort extracts (Hypericum perforatum) are applied to treat mild to moderate depression and possess wound healing properties. However, the chemical composition of the extracts varies with the genotype and is influenced by biotic and abiotic environmental factors, complicating the production of extracts with reproducible quality. In this thesis, the metabolite variation of H. perforatum and within the genus Hypericum was investigated. By combining analytical methods (TLC, NMR, NMR Pure Shift, LC-HRMS), secondary metabolites were detected untargeted and simultaneously. The data was further chemometrically evaluated. Comprehensive metabolomics studies of 93 H. perforatum genotypes from North America and Europe and 21 Hypericum species were used to identify efficacy-relevant variations in the metabolite composition. Furthermore, correlation analyses were used to reveal new aspects of the hypericin biosynthesis and to identify potential antibacterial constituents.

description: The field of exact exponential time algorithms for NP-hard problems has thrived over the last decade. While exhaustive search remains asymptotically the fastest known algorithm for some basic problems, difficult and non-trivial exponential time algorithms have been found for a myriad of problems, including Graph Coloring, Hamiltonian Path, Dominating Set and 3-CNF-Sat. In some instances, improving these algorithms further seems to be out of reach. The CNF-Sat problem is the canonical example of a problem for which the trivial exhaustive search algorithm runs in time O(2^n), where n is the number of variables in the input formula. While there exist non-trivial algorithms for CNF-Sat that run in time o(2^n), no algorithm was able to improve the growth rate 2 to a smaller constant, and hence it is natural to conjecture that 2 is the optimal growth rate. The strong exponential time hypothesis (SETH) by Impagliazzo and Paturi [JCSS 2001] goes a little bit further and asserts that, for every epsilon<1, there is a (large) integer k such that that k-CNF-Sat cannot be computed in time 2^{epsilon n}. In this paper, we show that, for every epsilon < 1, the problems Hitting Set, Set Splitting, and NAE-Sat cannot be computed in time O(2^{epsilon n}) unless SETH fails. Here n is the number of elements or variables in the input. For these problems, we actually get an equivalence to SETH in a certain sense. We conjecture that SETH implies a similar statement for Set Cover, and prove that, under this assumption, the fastest known algorithms for Steinter Tree, Connected Vertex Cover, Set Partitioning, and the pseudo-polynomial time algorithm for Subset Sum cannot be significantly improved. Finally, we justify our assumption about the hardness of Set Cover by showing that the parity of the number of set covers cannot be computed in time O(2^{epsilon n}) for any epsilon<1 unless SETH fails.

description: We analyze kinetically constrained 0-1 spin models (KCSM) on rooted and unrooted trees of finite connectivity. We focus in particular on the class of Friedrickson-Andersen models FA-jf and on an oriented version of them. These tree models are particularly relevant in physics literature since some of them undergo an ergodicity breaking transition with the mixed first-second order character of the glass transition. Here we first identify the ergodicity regime and prove that the critical density for FA-jf and OFA-jf models coincide with that of a suitable bootstrap percolation model. Next we prove for the first time positivity of the spectral gap in the whole ergodic regime via a novel argument based on martingales ideas. Finally, we discuss how this new technique can be generalized to analyze KCSM on the regular lattice $\mathbb{Z}^d$.

Subjects: L-ART/06 Cinema, fotografia e televisione

description: Considering the synchronism between the screening of American serials in China and the production of the first few Chinese feature-length films, this paper traces the interaction between Pearl White and Chinese actresses in the early 1920s. It demonstrates how Pearl White was absorbed into Chinese vernacular cinematic culture through the mediation of Chinese film actresses in the early years of Chinese filmmaking. Taking The Shun Pao [Chinese Daily News], one of the most influential newspapers in the 1920s, as its main resource and reconsidering Chinese film history in terms of modernity and gender, this paper reveals how American serial movies, especially “serial queens” such as Pearl White, created a new female image for Chinese movie-goers. It further explores how Yin Mingzhu (1904-1989), a Chinese actress known for her Pearl White-style attire in off-screen life, links Pearl White with the transformation of femininity of modern Chinese women and their search for a new self-image.

description: We study the resonance spectroscopy of the proton-rich nucleus 8C in the alpha+p+p+p+p cluster model. Many-body resonances are treated on the correct boundary condition as the Gamow states using the complex scaling method. We obtain the ground state of 8C as a five-body resonance for the first time, which has dominantly the sub-closed (p_{3/2})^4 configuration and agrees with the recent experiment for energy and decay width. We predict the second 0+ state with the excitation energy of 5.6 MeV, which corresponds to the $2p2h$ state from the ground state. We evaluate the occupation numbers of four valence-protons in the 8C states and also the J^πdistribution of proton-pair numbers of the two 0+ states of 8C. The ground state involves a large amount of the 2+ proton-pair fraction, while the excited 0+_2 state almost consists of two of the 0+ proton pairs, which can be understood from the (p_{3/2})^2(p_{1/2})^2 configuration. We also discuss the mirror symmetry between 8C and 8He with an alpha+four nucleon picture. It is found that the 0+ states retain the mirror symmetry well for the configuration properties of two nuclei.

description: In der vorliegenden Arbeit werden der anomale Hall-Effekt, der Spin-Hall-Effekt, der Edelstein-Effekt, und der Spin-Orbit-Torque in ferromagnetisch / nichtmagnetischen-Vielfachschichten mit substitutionellen Defekten untersucht. Die Beschreibung der elektronischen Struktur der ferromagnetisch / nichtmagnetischen-Vielfachschichten erfolgt im Rahmen der Dichtefunktionaltheorie mithilfe einer vollrelativistischen tight binding KKR-Greenschen Funktionsmethode. Der elektronische Transport wird durch die linearisierte Boltzmann-Gleichung bestimmt. Als Beispiel werden Co/Cu-Vielfachschichten sowohl mit Eigendefekten (Cu, Co) als auch mit Fremddefekten (Ir, Au, Bi) an verschiedenen Atompositionen innerhalb der Vielfachschichten betrachtet. Ferner werden Co/Cu-Vielfachschichten einerseits mit Magnetisierung M senkrecht zur Co/Cu-Grenzfläche und andererseits mit Magnetisierung M parallel zur Co/Cu-Grenzfläche behandelt.
description: In this thesis, the anomalous Hall effect, the spin Hall effect, the Edelstein effect, and the spin orbit torque in ferromagnetic/nonmagnetic multilayers with substitutional impurities are considered. The description of the electronic structure of the ferromagnetic/nonmagnetic multilayers is based on density functional theory by means of a fully relativistic tight binding KKR-Green’s function method. The electronic transport is calcluated using the linearized Boltzmann equation. As an example, Co/Cu multilayers with intrinsic impurities (Cu, Co) as well as extrinsic impurities (Ir, Au, Bi) delta-distributed in different atomic layers within the multilayers are considered. Furthermore, Co/Cu multilayers are taken into account with magnetization M perpendicular to the Co/Cu interface on the one hand and with magnetization M parallel to the Co/Cu interface on the other hand.

description: Durch die hohe Prävalenz funktioneller gastrointestinaler Erkrankungen besteht die Notwendigkeit einer eindeutigen schnellen Diagnostikmethode. Bislang konnten die in Studien beschriebenen Marker für IBS und FD nicht einheitlich durch nachfolgende Arbeiten bestätigt werden. Auch die zahlreichen Daten der Mikrobiomanalysen, liefern kein spezifisches Profil der verschiedenen Subgruppen. Unsere Studie war die erste, die eine kombinierte Betrachtung der serologischen Marker (Anti-CdtB- und Anti-Vinculin-Antikörper) und der Mikrobiotaveränderungen vorgenommen hat. Ziel war es zu untersuchen, ob subgruppenspezifische (IBS-D, IBS-C, FD und Gesunde) Unterschiede bei Anti-CdtB- und Anti-Vinculin-Titern, Mikrobiomprofilen sowie Dysbioseindizes vorliegen. Hierzu wurde eine ELISA gestützte Titerbestimmung der Antikörper, sowie eine Analyse der Mikrobiomprofile basierend auf der Sequenzierung der bakteriellen DNA zur Bestimmung der Mikrobiota und der Dysbioseindizes vorgenommen. Die Kernergebnisse, die unsere Studie liefert, sind 1), dass weder subgruppenspezifische Unterschiede in den fäkalen Mikrobiotaprofilen noch in den Anti-CdtB- und Anti-Vinculin-Titern vorliegen 2), dass ein signifikanter Zusammenhang zwischen Dysbiose und erhöhten Anti-CdtB-Werten vorliegt, der auf eine neue ätiologische Verbindung der dysbiose-abhängigen Anti-CdtB Bildung hindeuten kann und 3), dass die höheren Dysbioseindizes der IBS-C Kohorte durch signifikant erhöhte proinflammatorische- und erniedrigte butyratbildende Bakterien getrieben werden. Diese Erkenntnisse liefern für zukünftige Studien neue Anhaltspunkte der Biomarkerforschung und bieten die Möglichkeit, durch gezieltes Ausgleichen der jeweils veränderten Mikrobiota, den dysbiotischen Veränderungen bei FGIDs entgegenwirken zu können.
Synthesis, evaluation, and application of new ligands for radiometal based radiopharmaceuticals
Creators: name: Price, Eric William
Publisher: name: University of British Columbia
Year: 2014

description: Radiometals comprise many useful radioactive isotopes of various metallic elements. When properly harnessed, these have valuable emission properties that can be used for diagnostic imaging techniques, such as single photon emission computed tomography (SPECT, e.g. ⁶⁷Ga, ⁹⁹mTc, ¹¹¹In, ¹⁷⁷Lu) and positron emission tomography (PET, e.g. ⁶⁸Ga, ⁶⁴Cu, ⁴⁴Sc, ⁸⁶Y, ⁸⁹Zr), as well as therapeutic applications (e.g. ⁴⁷Sc, ¹¹⁴mIn, ¹⁷⁷Lu, ⁹⁰Y, ²¹²/²¹³Bi, ²¹²Pb, ²²⁵Ac, ¹⁸⁶/¹⁸⁸Re). A fundamental critical component of a radiometal-based radiopharmaceutical is the ligand that binds the radiometal ion in a tight stable coordination complex so that it can be properly directed to a desirable molecular target in vivo. This thesis describes the design, synthesis, and evaluation of novel acyclic ligands based on the versatile picolinic acid moiety. Acyclic ligands have been selected because facile ambient temperature radiolabeling is an important property when working with heat sensitive molecules such as antibodies, as many currently used ligands require high temperatures for optimal radiolabling performance. Previous work in the Orvig group has determined the acyclic ligand H₂dedpa to possess ideal properties for ⁶⁷/⁶⁸Ga radiochemistry. In light of this success, this thesis has been dedicated to expansion of the H₂dedpa molecular scaffold to accommodate larger radiometals with ligand denticities ranging from 8-10. Once synthesized, new ligands are studied by standard chemical characterization, as well as potentiometric titrations to determine thermodynamic stability parameters, and radiolabeling and in vitro/in vivo stability studies of both “bare” ligands and antibody bioconjugates. The ligand H₄octapa is a highlight of this body of work, and has been found to possess excellent properties with the radiometals ¹¹¹In and ¹⁷⁷Lu, matching or in some cases surpassing the current industry “gold standard” ligand DOTA. A second highlight is the ligand H₆phospa, which is demonstrated to possess enhanced ⁸⁹Zr radiolabeling properties to H₄octapa, showing the best ⁸⁹Zr radiolabeling performance of any new ligand in several decades, with only DFO retaining superior properties.

description: In this article we investigate fertility intentions of Russian women in Estonia from an origin-destination perspective. Russian migrants to Estonia and their descendants are compared with women in the sending and host countries in order to identify similarities and differences in intended transitions to first, second and third births. The study is based on the Estonian and Russian Generations and Gender Surveys, which were conducted in 2004/2005, and employs logistic regression models. The dependent variables are intentions to become a mother, to have a second child, or to have a third child. The hypotheses for the study are mainly derived from the adaptation, cultural maintenance, and selection (characteristics) perspectives. We also incorporate attitudes towards gender roles into the models, which have proven to be a salient factor in shaping childbearing intentions, but have seldom been considered in studies of migrant fertility.

Our results lend support to both the adaptation and cultural maintenance perspectives. In accord with the latter, the similarity between the childbearing intentions of Russian migrants and their descendants in Estonia and those of their counterparts in Russia suggests that socialisation to the ethnic subculture has prevailed over the influence of the host society. We attribute this outcome to contextual features that have retarded integration processes. By contrast, we observe that proficiency in the host country language, residence in areas where the host population constitutes a large majority and having a native partner significantly contribute to the adaptation of migrants’ intentions to have another child to those of the host population. These results provide support to the adaptation argument. Finally, our study reveals a positive association between egalitarian views on gender roles and women’s intentions to have another child. However, variation in gender role attitudes accounts for a relatively minor part of the difference in intended fertility between the groups addressed in this study.

The Passionate Eye of Angelina Buracci, Pedagogue

description: This paper examines the contribution of Angelina Buracci, a young feminist and pacifist pedagogue, to the early discourse on film in Italy. Published in 1916, her book Cinematografo educativo [educational cinema] is a brilliant counter to the contemporary representation of women filmgoers in the writings of several Italian male modernist intellectuals. Their construction, between 1908 and 1930, of a new canon of spectatorship centered on the figure of the male cinephile and bears traces of a gendered discourse. In the minds of these intellectuals, the “new spectator” was evoked as an alternative to an earlier, female model of spectatorship. Yet, despite their dismissal of women’s significant presence in the early discursive field, a few women writers had already begun carving out their own space in reflections on cinema. Buracci’s essay is an exemplary document in this respect. Not only does it demonstrate the author’s familiarity with the experience of cinema, but it also reveals an extraordinary independence of thought.

description: This is the first part of some thoughts toward how to open up again the question of the theoretical issues around the expressivity of the body, especially given the example of silent cinema. It is an old semiotic problem of what meanings words convey and what the body without words can be said to “express.” After deciding that “silence” is not the operative concept we want I return briefly to the no-word advocates like Béla Balász, and “pure cinema” theorists Germaine Dulac, Jean Epstein, and Louis Delluc, as well as to Christian Metz who was highly dismissive of what he called the “gibberish” of the silent screen. Peter Brooks comes in for some scrutiny for coming so close in his “Text of Muteness” chapter in The Melodramatic Imagination, but I find that he still sits on the fence, wanting to give the day to silent expression, but then signaling a preference for words. So I keep asking what is meant by the phrase “words cannot express,” wanting to know if this means that they fall short or that other signs must take up the slack, or that words will never substitute for gestures. Concluding with Lillian Gish’s essay on “Speech Without Words” and Asta Nielsen’s position that the American cinema had too many words, I call this an exercise in defining a problem although I do not consider this project anything more than “to be continued.”
A Pendulum of Performances: Asta Nielsen on Stage and Screen

description: Asta Nielsen turned to filmmaking in June 1910 because she was dissatisfied with the minor parts that the Danish theatres were offering her. She aspired big dramatic roles and hoped to convince theatre directors of her talent. Instead, her striking film performance launched her prolific career as a film star who virtually personified screen acting. The focus on Nielsen’s work in the cinema, however, has often obscured the significance of the stage performances for her career. This article explores and contextualizes Nielsen’s actual stage acting as well as references to the theatre within her films. Nielsen’s pantomime performances in the 1910s informed a discussion how variety shows and cinema could benefit from one another; her adaptations of plays in the early 1920s revitalized the debate how to adapt theatre to film; and her star performances in popular plays in the late 1920s, when she toured all over Germany, were an alternative for film parts she deemed inapt for her intense physical and mimic acting style. Asta Nielsen employed the cinema to develop her unsurpassed acting style and to establish her sovereignty as an actress, but the stage ultimately enabled her to maintain her art and position.

description: Sarah Bernhardt is a paradigmatic case study for the joining of voice and silent film. This is because she was famous for her “voix d’or” on the theatrical stage and because she was highly visible in the nascent period of the cinema’s development. Traditionally considered an example of an actress in the early cinema who was “silenced” by film, she has also been considered an anachronistic and ineffective on-screen performer. I argue instead that Bernhardt’s films were not mute records of her live stage action but works that further promoted and developed her polymorphous body at the opening of the twentieth century.

The dynamics derived is a generalized geometric Brownian motion; from the Black & Scholes formula the calibration of both the Minority Game and the Grand Canonical Minority Game, by means of their characteristic parameters, is performed. We conclude that for both games the asymmetric phase with characteristic parameters close to critical ones is coherent with options implied volatility market.

description: Let $C\subset {\mathbb R}^n$ be a convex body. We introduce two notions of convexity associated to C. A set $K$ is $C$-ball convex if it is the intersection of translates of $C$, or it is either $\emptyset$, or ${\mathbb R}^n$. The $C$-ball convex hull of two points is called a $C$-spindle. $K$ is $C$-spindle convex if it contains the $C$-spindle of any pair of its points. We investigate how some fundamental properties of conventional convex sets can be adapted to $C$-spindle convex and $C$-ball convex sets. We study separation properties and Carathéodory numbers of these two convexity structures. We investigate the basic properties of arc-distance, a quantity defined by a centrally symmetric planar disc $C$, which is the length of an arc of a translate of $C$, measured in the $C$-norm, that connects two points. Then we characterize those $n$-dimensional convex bodies $C$ for which every $C$-ball convex set is the $C$-ball convex hull of finitely many points. Finally, we obtain a stability result concerning covering numbers of some $C$-ball convex sets, and diametrically maximal sets in $n$-dimensional Minkowski spaces.

description: We report the observation of a pseudogap in the \emph{ab}-plane optical conductivity of underdoped Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$ ($x = 0.2$ and 0.12) single crystals. Both samples show prominent gaps opened by a spin density wave (SDW) order and superconductivity at the transition temperatures $T_{\it SDW}$ and $T_c$, respectively. In addition, we observe an evident pseudogap below $T^{\ast} \sim$ 75 K, a temperature much lower than $T_{\it SDW}$ but much higher than $T_{c}$. A spectral weight analysis shows that the pseudogap is closely connected to the superconducting gap, indicating the possibility of its being a precursor of superconductivity. The doping dependence of the gaps is also supportive of such a scenario.

Here we develop an NMQSD method to study the open quantum system in fermionic environments. This problem involves anticommutative noise functions (i.e., Grassmann variables) that are intrinsically different from the noise functions of bosonic baths. We obtain the NMQSD equation for quantum states of the system and the non-Markovian master equation. Moreover, we apply this NMQSD method to single and double quantum-dot systems.

description: This article introduces and solves a general class of fully coupled forward-backward stochastic dynamics by investigating the associated system of functional differential equations. As a consequence, we are able to solve many different types of forward-backward stochastic differential equations (FBSDEs) that do not fit in the classical setting. In our approach, the equations are running in the same time direction rather than in a forward and backward way, and the conflicting nature of the structure of FBSDEs is therefore avoided.

description: Many stochastic differential equations (SDEs) in the literature have a superlinearly growing nonlinearity in their drift or diffusion coefficient. Unfortunately, moments of the computationally efficient Euler-Maruyama approximation method diverge for these SDEs in finite time. This article develops a general theory based on rare events for studying integrability properties such as moment bounds for discrete-time stochastic processes. Using this approach, we establish moment bounds for fully and partially drift-implicit Euler methods and for a class of new explicit approximation methods which require only a few more arithmetical operations than the Euler-Maruyama method. These moment bounds are then used to prove strong convergence of the proposed schemes. Finally, we illustrate our results for several SDEs from finance, physics, biology and chemistry.

description: We define cylindric generalisations of skew Macdonald functions when one of their parameters is set to zero. We define these functions as weighted sums over cylindric skew tableaux: fixing two integers n>2 and k>0 we shift an ordinary skew diagram of two partitions, viewed as a subset of the two-dimensional integer lattice, by the period vector (n,-k). Imposing a periodicity condition one defines cylindric skew tableaux as a map from the periodically continued skew diagram into the integers. The resulting cylindric Macdonald functions appear in the coproduct of a commutative Frobenius algebra, which is a particular quotient of the spherical Hecke algebra. We realise this Frobenius algebra as a commutative subalgebra in the endomorphisms over a Kirillov-Reshetikhin module of the quantum affine sl(n) algebra. Acting with special elements of this subalgebra, which are noncommutative analogues of Macdonald polynomials, on a highest weight vector, one obtains Lusztig's canonical basis. In the limit q=0, one recovers the sl(n) Verlinde algebra, i.e. the structure constants of the Frobenius algebra become the WZNW fusion coefficients which are known to be dimensions of moduli spaces of generalized theta-functions and multiplicities of tilting modules of quantum groups at roots of unity. Further motivation comes from exactly solvable lattice models in statistical mechanics: the cylindric Macdonald functions arise as partition functions of so-called vertex models obtained from solutions to the quantum Yang-Baxter equation. We show this by stating explicit bijections between cylindric tableaux and lattice configurations of non-intersecting paths. Using the algebraic Bethe ansatz the idempotents of the Frobenius algebra are computed.

description: The Parisi formula for the free energy in the Sherrington-Kirkpatrick and mixed $p$-spin models for even $p\geq2$ was proved in the seminal work of Michel Talagrand [Ann. of Math. (2) 163 (2006) 221-263]. In this paper we prove the Parisi formula for general mixed $p$-spin models which also include $p$-spin interactions for odd $p$. Most of the ideas used in the paper are well known and can now be combined following a recent proof of the Parisi ultrametricity conjecture in [Ann. of Math. (2) 177 (2013) 383-393].

Silent Singers. The Legacy of Opera and Female Stars in Early Italian Cinema

description: Although opera has undoubtedly been an important point of reference for the silent film industry, it didn’t left a conspicuous amount of traces that could allow us today to carry out wide- ranging research. This paper aims to fill this gap trying to reconstruct the relationship between opera and the silent cinema in a particular country, such as Italy, where the culture of melodrama in the early twentieth century was not only widespread among the cultural élite but also familiar to a large section of the population. My contribution explores different items: the technological perspective; the involvement of the main Italian composers into the emerging movie industry; the role played by music publishers and film companies in order to reinforce integration between these media; finally the key role of the singer-actress. This last item is really significant. Indeed the character of singer- actress reaches on a profound symbolic meaning, and at same time reveals both the potentials and limitations of silent movie. Finally, I will show how the paradoxical status of “silent singer” is a very fructuous item to depict the identity of both silent cinema and opera in the well-known home of “bel canto.”
A Tribute to Her Creativity: Maria Gasparini in The Stage

description: If we accept that the practice of filmmaking is based on the pleasure and desire to appropriate and control an image, it seems hardly surprising that film directors can fall in love with film stars, and vice versa. In the collective imagination, the actress is malleable material in the hands of her male partner-creator. This rigid definition of gender roles within the creative process has been surprisingly challenged and explored in an Italian melodrama of 1912, The Stage (La Ribalta). In it, a noblewoman who has been prompted by an actor (her lover) to step on the stage for fun reveals an uncanny talent for acting. Unable to deal with the humiliation of coming second to this talent, her mentor becomes envious and causes a tragedy. The leading role was played by Maria Gasparini, one of the most appreciated intellectual actresses of Italian early cinema. More interestingly, the film was directed by Gasparini’s own husband, Mario Caserini, who treated the subject as a delicate, sincere homage to his partner, focusing on her character as the true creative genius within the fictional couple.

description: The First World War created disfigured and mutilated bodies on a grand scale. Never before had the bodies of soldiers been so devastated by a conflict. Developments in established weapons such as cannons and machine guns, and terrifying innovations such as poison gas, created a relative army of disfigured and mutilated men. Some men lost multiple limbs and sensory organs such as eyes. No part of the body was safe from the potential of severe and life-changing wounds. Owing to new and advanced medical specialities, surgical techniques, and technical innovations, soldiers survived wounds that in previous conflicts might have killed them. Wounds healed, but often bodies were left badly disfigured and mutilated. These men had to manage not only the result of their bodily wounds, but also their emotional trauma and their new role as disabled veterans. For these damaged men, their war was over, but recovery, rehabilitation, and reintegration presented a new set of challenges.

Subjects: L-ART/06 Cinema, fotografia e televisione

description: The role of women in silent era cinema has become increasingly important in recent cinema scholarship. One aspect of this current scholarship is the appearance of the female star and the social, industrial and ideological forces that contribute to the construction of the star system. The Khanzhonkov studio, founded and directed by Alexander Khanzhonkov, Khanzhonkov & Co., was one of the leading studios in Russia prior to the Revolution. Taking a cue from recent scholarship on the variety of women’s roles in the cinema, and building on the work of academics such as historian Denise Youngblood and film scholar Yuri Tsivian, this paper will explore some of the practices and policies of Alexander Khanzhonkov and his studio.

description: Die vorliegende Arbeit untersucht den Effekt von global veränderten 𝑉̇ 𝐴𝑄̇⁄ - Verhältnissen in der Lunge auf die Aufnahme und Elimination des Inhalationsanästhetikums Desfluran in einer tierexperimentellen Studie an juvenilen Schweinen. Hierzu inhalierten, nach Induktion und Aufrechterhaltung einer totalen intravenösen Allgemeinanästhesie, 7 Tiere für drei 𝑉̇ 𝐴𝑄̇⁄ - Verhältnisse Desfluran über 45 min. Im ersten Zyklus wurden die Desfluran - Partialdrücke bei einem unveränderten, normalen 𝑉̇ 𝐴𝑄̇⁄ der Lunge gemessen. Das um ≈ 66 % verringerte 𝑉̇𝐴𝑄̇⁄ - Verhältnis im zweiten Versuchszyklus wurde über eine Dobutamingabe und ein Herabsetzen der Atemfrequenz erreicht. Durch das Einführen und Füllen eines Ballonkatheters in den rechten Vorhof der Tiere und das Steigern der Atemfrequenz konnte das 𝑉̇ 𝐴𝑄̇⁄ - Verhältnis im dritten Versuchszyklus um ≈ 55 % gesteigert werden. Die arteriellen und pulmonal - venösen Desfluran - Partialdrücke wurden zu 8 Zeitpunkten während der Aufnahme und Elemination in jedem Versuchszyklus gemessen. Das 𝑉̇ 𝐴𝑄̇⁄ - Verhältnis der Lunge hatte einen erheblichen Einfluss auf die Pharmakokinetik des Inhalationsanästhetikums Desfluran, insbesondere auf den arteriellen Partialdruck. Verglichen mit dem normalen 𝑉̇ 𝐴𝑄̇⁄ - Verhältnis, erhöhte ein erniedrigtes 𝑉̇ 𝐴𝑄̇⁄ - Verhältnis die Zeitspanne, bis zu der 90 % des maximalen Partialdrucks (p90) im arteriellen Blut erreicht bzw. eliminiert wurden; sowohl während der Aufnahme (von ≈ 6 min auf ≈ 39 min) als auch während der Elimination (von ≈ 7 min auf ≈ 20 min). Ein erhöhtes 𝑉̇ 𝐴𝑄̇⁄ - Verhältnis verzögerte nur die Aufnahme des Gases (von ≈ 6 min auf ≈ 23 min) in das arterielle Blut.
However Odd—Elsa Lanchester!

description: The article is concerned with Elsa Lanchester as an anti-star figure in British Cinema in the 1920s. It makes a comparison with the performance style of Alexandra Khokhlova in films made with the Kuleshov Workshop in Russia, suggesting that both actresses drew on a similar range of sources (notably, Bode, Duncan, Jaques-Dalcroze and Chaplin). While both seem willing to parodize themselves, embracing ugliness, their eccentrism simultaneously provides something of an ironic commentary on the ideal feminine “types” presented by Hollywood and Hollywood’s commodification of particular notions of feminine beauty.

description: Ziel dieser sozialepidemiologischen Querschnittsstudie war es, orale Gesundheitsparameter (Karies, Parodontopathien, dentales Trauma, kieferorthopädische Anomalien, Dentalfluorosen) ghanaischer Kinder im Alter von 3 - 13 Jahren zu untersuchen, wobei der Schwerpunkt auf der Analyse regionaler Unterschiede einer städtischen und ländlichen Region lag. Dabei wurde sich der standardisierten klinischen Mundgesundheitsuntersuchung im schulischen Setting sowie der anamnestischen Datenerhebung mit Hilfe von Elternfragebögen zu verhaltensbezogenen und sozialdemografischen Einflussfaktoren bedient. Es wurden Zusammenhänge zwischen Karies und den assoziierenden Faktoren elterliche Schulbildung, Mundhygiene und Ernährung evaluiert. Zudem wurde der Fluoridgehalt vor Ort gewonnener Trinkwasserproben bestimmt. Diese Arbeit leistet einen Beitrag zur Aktualisierung der Datenlage zur Mundgesundheit von ghanaischen Kindern sowie zur Etablierung von zahnärztlichen Schuluntersuchungen in Ghana.
description: This cross-sectional socio-epidemiological study aimed to examine oral health parameters (caries, periodontal disease, dental trauma, orthodontic anomalies, dental fluorosis) of Ghanaian children aged 3 - 13 years while focusing on the analysis of regional disparities between an urban and rural region. Standardised clinical oral health examination was conducted in school facilities and a parental questionnaire was applied to gather data considering behavioural and socio-demographic determinants. Correlations between caries and the associating factors of parental education level, oral hygiene, and diet were evaluated. Additionally, the fluoride content of drinking water samples obtained on-site was determined. This work contributes to updating data on oral health of Ghanaian children and to the establishment of dental school examinations in Ghana.

description: Die zunehmende Bedeutung des Konsums pychoaktiver Substanzen für die Entstehung von Krankheiten macht eine Anpassung der Präventions- und Hilfsangebote notwendig. Für die Erarbeitung neuer Ansatzpunkte in diesem Bereich wurden Konsum und Kognitionen von Nutzer:innen illegaler Drogen ohne laufende Therapie erforscht. Nach den Grundsätzen der Grounded Theory Methodologie wurden hierfür 13 leitfadengestützte Interviews im Raum Halle-Leipzig durchgeführt und ausgewertet. Als Leitmotive des Konsums konnten Flucht, Selbsterkenntnis und Hedonismus identifiziert werden. Für die Entstehung dieser Motive waren wiederum verschiedene Lebensumstände und -perspektiven bedeutsam. Zentrale Erwartungen der Interviewten gegenüber Ärzt:innen waren ein respektvoller Umgang und fundiertere fachliche Informationen. Durch eine Berücksichtigung der Konsummotive, sowie der Lebensumstände und eine angemessene Beratung kann die Begegnung mit Drogennutzer:innen verbessert und Schaden reduziert werden.
description: The increasing importance of the use of pychoactive substances for the pathogenesis of diseases makes it necessary to adapt prevention and support programs. In order to find new starting points for improved approaches, we investigated the consumption and cognitions of drug users who did not undergo therapeutical treatment at the time of research. Following grounded theory methodology, 13 guided interviews with users of illegal drugs were conducted and analyzed in the Halle-Leipzig area. Escapism, self-discovery and hedonism were identified as central motives for consumption, with different causes and backgrounds. Central expectations towards physicians were a respectful interaction and more well-founded professional information. Taking into account the motives for consumption, respectful professional counselling and an improvement of living circumstances can support the reduction of harm caused by substance use.
