Empowered Women Resist: Three Black women Journalists in the Struggle for Civil Rights
Creators: name: Salleh, Fatimah Sarifah
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: The Civil Rights Movement, 1947-1968, was a time of great change and resistance for African Americans. The black press played a crucial role as African-American journalists conveyed the hopes and frustrations of their people and rallied citizens to fight for their rights. Although previously understudied, a number of the most powerful writers of the era were black female journalists. This dissertation examines the lives and work of journalists and journalism educators Lucile Bluford, Francis Murphy, and Dorothy Gilliam, based on analysis of their writing and oral histories recorded as part of the Washington Press Club's Oral History Project. Black feminist, alternative, and ethnic media theories are used to understand these women's lives and work. Frances L. Murphy's reign as the owner and editor of the long standing Afro-American newspaper provides a distinct look at black-centered advocacy writing during the Civil Rights era. In contrast, Dorothy Gilliam migrated from the black press to the noted mainstream paper, the Washington Post, and became its first black female editor. Lucile Bluford battled for racial equity in the ranks of journalism education and contested the University of Missouri's segregated admittance policies while pursuing a 30-year career as reporter, editor, and eventual proprietor of the Kansas City Call Although the life story of each woman is unique, the similarities of their focus and approach were striking. All three women fought throughout their lives for racial parity. They fought for school segregation despite their positive experiences with black schooling. Their voices championed voting rights and health care in the black community, and they encouraged their readers to participate in the struggle for equality. They spoke out against police brutality and raised money to fuel worthy causes. All three women spoke and wrote about those who had paved their way, lauded their successful contemporaries, and expressed gratitude for the black men who were their mentors and advocates.
A Crisis of Marriage? The Debate on Marriage Reform in the Social Democratic Women’s Press, 1919-1933
Creators: name: Stiglich, Larissa R.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Article 119 of the new constitution of the Weimar Republic established marriage as the foundation of family life and placed it under special protection of the constitution. Although women were also guaranteed equal political rights under the new constitution, their civil rights remained regulated by the Civil Code of 1900. Representatives of the women's movement had criticized the Civil Code since its implementation. Following women's experiences of increased independence during the First World War and their changed economic, social, and political circumstances in Weimar Germany, even more women's groups demanded a reform of marriage and family law. This thesis explores the discourses surrounding marriage reform in the Social Democratic women's press of the Weimar Republic. It reveals that they neither agreed on the causes of the perceived crisis of marriage, nor on the necessary measures for a marriage reform. This diversity of thought reflects not only the process of renegotiating gendered marital roles within the quickly changing political, social, economic and cultural circumstances of the Weimar Republic, but it also illuminates Social Democratic women's political activism. Taken together, these discourses shed light on the complicated process of redesigning marriage in shifting social circumstances.

description: We present a novel cortically-inspired image completion algorithm. It uses a five dimensional sub-Riemannian cortical geometry modelling the orientation, spatial frequency and phase selective behavior of the cells in the visual cortex. The algorithm extracts the orientation, frequency and phase information existing in a given two dimensional corrupted input image via a Gabor transform and represent those values in terms of cortical cell output responses in the model geometry. Then it performs completion via a diffusion concentrated in a neighbourhood along the neural connections within the model geometry. The diffusion models the activity propagation integrating orientation, frequency and phase features along the neural connections. Finally, the algorithm transforms back the diffused and completed output responses back to the two dimensional image plane.

description: We study classes of right-angled Coxeter groups with respect to the strong submodel relation of parabolic subgroup. We show that the class of all right-angled Coxeter group is not smooth, and establish some general combinatorial criteria for such classes to be abstract elementary classes, for them to be finitary, and for them to be tame. We further prove two combinatorial conditions ensuring the strong rigidity of a right-angled Coxeter group of arbitrary rank. The combination of these results translate into a machinery to build concrete examples of $\mathrm{AECs}$ satisfying given model-theoretic properties. We exhibit the power of our method constructing three concrete examples of finitary classes. We show that the first and third class are non-homogeneous, and that the last two are tame, uncountably categorical and axiomatizable by a single $L_{ω_{1}, ω}$-sentence. We also observe that the isomorphism relation of any countable complete first-order theory is $κ$-Borel reducible (in the sense of generalized descriptive set theory) to the isomorphism relation of the theory of right-angled Coxeter groups whose Coxeter graph is an infinite random graph.
Some heroic discipline: William Butler Yeats and the Oxford Book of Modern Verse
Creators: name: Rubin, Robert Alden
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This project explores William Butler Yeats's work as editor of the 1936 Oxford Book of Modern Verse, with emphasis on Yeats's sense of his own place among the poets of his day. The study considers all of the 379 poems by the ninety-seven writers included in the anthology (as well as notable omissions) in the context of Yeats's critical writings and correspondence; where possible, it identifies the sources consulted by Yeats for his selections, and the circumstances of publication. It also examines the degree to which Yeats saw the anthology as a way to influence the emerging literary consensus of the mid-1930s. Finally, it argues that the anthology offers the same essentially neo-Romantic critique of modernity that can be found in Yeats's own poems -- a sense that to be modern is to wrestle with an impulse to believe, despite circumstances that weaken the basis for such belief. Chapter I relates the details of the book's conception, gestation, and publication. Chapter II addresses the late-Victorian poets, including both avant-garde decadents with whom he identified and late-Victorian mainstream poets against whom he reacted. Chapter III explores Yeats's selections from contemporaries among the Edwardian-era writers, including those whose modern sensibility separated them from the Victorians. Chapter IV considers the many Irish poets that Yeats included in the anthology, and the ways in which the Irish experience embodied the modern problem for him. Chapter V addresses his reaction to the Georgian-era writers and war poets whose sensibility was shaped before the First World War, but whose best-known work appeared during and after it. Finally, Chapter VI considers the modernist poets inspired by T. S. Eliot and Ezra Pound, whom he answered with a more idiosyncratic version of what it meant to be modern.

description: We prove a number of p-adic congruences for the coefficients of powers of a multivariate polynomial f(x) with coefficients in a ring R of characteristic zero. If the Hasse--Witt operation is invertible, our congruences yield p-adic limit formulas which conjecturally describe the Gauss--Manin connection and the Frobenius operator on the unit-root crystal attached to f(x). As a second application, we associate with f(x) formal group laws over R. Under certain assumptions these formal group laws are coordinalizations of the Artin--Mazur functors. (This is a final version which we send for a publication.)

DNA Degradation: The Effect of Oil Red O on Recovered DNA
Creators: name: Roman, Jasmine E
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Forensic examiners must decide which fingerprint enhancement technique is best fit for further downstream DNA processing. The dominant understanding is to limit the number of enhancement techniques on fingerprints since more DNA is lost the more enhancement techniques are applied. Literature studies perform these experiments with samples stored in room temperature or freezer conditions and have DNA tested from time points of hour 0, hour 24, 7 days, and 14 days. Although this is common literature practice, crime labs across the United States test their DNA evidence across a large range of days with the latest being an average of about 140 days after booking. This study investigated the effects of the single reagent Oil Red O (ORO) combined with DNA while being in-solution and dried on microscope slides in either room temperature or freezer conditions. Samples were collected at hourly time points of 0, 1, 2, 4, 8, and 24 hours along with day time points of 0, 1, 2, 7, 14, 28, 35, 56, 84, 112, and 140 days. DNA was extracted using the phenol-chloroform gold standard extraction method and quantified with Quantifilier™ Trio DNA Quantification kit. DNA quantities and the DNA degradation index were analyzed. Due to untreated samples and ORO-treated samples yielding insignificant results between DNA quantities, it is concluded that ORO does not affect the quantity of DNA found. However, since there was a statistically significant difference in DNA degradation, ORO, through some unknown mechanism, negatively affects the quality of DNA. The significant difference in DNA quantities through passing storage time is therefore concluded to be due to time itself and not ORO.

description: There is a one-to-one correspondence between associated families of generic conformally flat (local-)hypersurfaces in 4-dimensional space forms and conformally flat 3-metrics with the Guichard condition. In this paper, we study the space of conformally flat 3-metrics with the Guichard condition: for a conformally flat 3-metric with the Guichard condition in the interior of the space, an evolution of orthogonal (local-) Riemannian $2$-metrics with constant Gauss curvature $-1$ is determined; for a $2$-metric belonging to a certain class of orthogonal analytic $2$-metrics with constant Gauss curvature $-1$, a one-parameter family of conformally flat 3-metrics with the Guichard condition is determined as evolutions issuing from the $2$-metric.

The Role of SOX2 in the Development of the Optic Cup, Hypothalamus and Secondary Palate
Creators: name: Langer, Lee F.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: SOX2 is a HMG domain-containing transcription factor expressed in all neural progenitor cells of the developing and adult nervous system. Several critical properties of neural progenitors, including the ability to self-renew and pluripotency, depend on Sox2 function. SOX2 haploinsufficient humans exhibit abnormalities in tissues that derive from the neural ectoderm and in several facial structures. Previous models of this disorder have been limited in their descriptive ability. The generation of mice hypomorphic for Sox2 (Sox2HYP) has allowed an analysis of Sox2 function in an environment in which its dosage is constitutively lower. A previous study of these mice confirmed their value as a model for SOX2 haploinsufficiency but was limited to later developmental stages; it is therefore unknown (i) what developmental events lead to the observed phenotypes and (ii) whether these mice exhibit other abnormalities observed in cases of SOX2 haploinsufficiency (Taranova, et al., 2006). Therefore, this thesis was undertaken with the following hypotheses: (i) mouse embryos that are hypomorphic for Sox2 (Sox2HYP) will exhibit early ocular, neural, and craniofacial defects that are consistent with the phenotypes that are observed in humans with SOX2 haploinsufficiency, and (ii) the molecular analyses of these developing tissues and structures in the Sox2HYP mouse embryo will provide information regarding the specific function of Sox2 in the development of the brain and eye. It was found that prior to E10.5, Sox2HYP optic primordia do not exhibit altered proliferation or apoptosis; however, abnormal neural retina pattering is observed at E10.5. Furthermore, the optic stalk is hypoplastic, exhibits increased apoptosis, and contributes to an abnormal OC orientation. Also observed was an abnormal broadening of the posterior prechordal floor, a defect encompassing the tuberal hypothalamus and characterized by abnormal expression of genes within the sonic hedgehog (Shh) signaling pathway. This work also illustrates Sox2's participation in secondary palatal development, specifically in the development of the palatal shelves. The palatal abnormality presents at E14.5, affects approximately two-thirds of Sox2HYP pups, and likely does not result from retrognathia. Overall, the tested hypotheses have been proven, providing important information regarding SOX2 haploinsufficiency-related defects that involve the eyes, brain, and secondary palate.
SOCIAL MEDIA-BASED SOCIAL CAPITAL ON PSYCHOLOGICAL WELL-BEING: EXPLORING THE MEDIATIONAL ROLE OF SELF-ESTEEM

description: The trend of intensive social media utilization signifies the importance of technologies in individual lives to interact with recent and original connections. Concurrently, social media facilitate communication and reflection on personal and social issues to elevate self-esteem and psychological well-being. The present study aimed to empirically appraise three types of social media-based social capital on self-esteem and psychological well-being. A web-based cross-sectional survey was implemented to collect data from 240 Jordanian respondents. Subsequently, partial least square structural equation modelling (PLS-SEM) and artificial neural network (ANN) analysis were performed on the collected data. The findings demonstrated that the bonding, bridging, and maintaining social capital significantly increased self-esteem levels before significantly harnessing psychological well-being. Furthermore, self-esteem significantly mediated the association between social capital (bonding and bridging) and psychological well-being. Similarly, the ANN analysis revealed that self-esteem with social capital bonding and maintaining were the three significant psychological well-being predictors. Resultantly, the study outcomes shed light on the importance of social media-based social capital in nurturing self-esteem and psychological well-being, in which the mediational role of self-esteem is vital to establishing psychological well-being. As personal social media requirements vary amongst individuals, social media activities could also engender negative psychological well-being, which necessitates the achievement of optimal self-esteem degrees from social media usage to attain an appropriate psychological well-being level.

Σκοπός: Ο σκοπός της παρούσας συστηματικής ανασκόπησης ήταν να αξιολογηθεί η επίδραση της μεθόδου STAN σε σύγκριση με το συμβατικό CTG όσον αφορά τις περιγεννητικές και νεογνικές εκβάσεις. Μέθοδοι: Διεξήχθη μια αναζήτηση στις ηλεκτρονικές βάσεις δεδομένων (PubMed, Cochrane, Scopus) για τον εντοπισμό τυχαιοποιημένων ελεγχόμενων δοκιμών (RCTs) στην Αγγλική γλώσσα. Στις εκβάσεις περιλαμβάνονταν οι παρεμβατικοί τοκετοί, η αιμοληψία από το τριχωτό της κεφαλής του εμβρύου (FBS), η μεταβολική οξέωση, ο περιγεννητικός και νεογνικός θάνατος, οι νεογνικές κρίσεις, η νεογνική εγκεφαλοπάθεια, η μεταφορά στη μονάδα εντατικής νοσηλείας νεογνών (NICU) και η βαθμολογία Apgar. Αποτελέσματα: Στην ανασκόπηση συμπεριελήφθησαν επτά RCTs. Οι δύο πρώτες RCTs έδειξαν ότι ο συνδυασμός STAN και CTG είναι καλύτερη επιλογή από τη χρήση μόνο του CTG καθώς αποδείχθηκε μείωση του ποσοστού των παρεμβατικών τοκετών λόγω εμβρυϊκής δυσφορίας και μείωση της μεταβολικής οξέωσης. Όμως, οι μελέτες που ακολούθησαν δεν έδειξαν στατιστικά σημαντικές αλλαγές με τον συνδυασμό των μεθόδων, εκτός από τη μείωση της συχνότητας του FBS. Συμπεράσματα: Τα ευρήματα από τις RCTs ήταν διαφορετικά και αντικρουόμενα. Οι περισσότερες μελέτες δεν αναγνώρισαν την υπεροχή του συνδυασμού των δυο μεθόδων σχετικά με τους παρεμβατικούς τοκετούς και τις νεογνικές εκβάσεις, αλλά μεταξύ των μελετών υπήρχαν πολλές μεθοδολογικές διαφορές.

description: This acute field-experimental study examined the effect of self-regulated learning on elementary school students’ executive functions. Students participated in physical education classes. Three fifth-grade classes (59 students, 27 boys and 32 girls) and three fourth-grade classes (52 students, 32 boys and 20 girls) from three elementary schools were randomly assigned to two experimental groups and a control group. Group 1 received teaching based on the observation and emulation levels of Zimmerman’s model, Group 2 received teaching based on the self-control level of this model, and Group 3 (control) received a theoretical presentation. The results showed that Group 2 students’ executive functions improved significantly more than Group 1, while Group 3 showed no improvement. The results are discussed in the context of self-regulation teaching in physical education and in relation to research on the acute effects of physical activity on executive functions.

description: The continuous electrification of the mobility and heating sectors adds much-needed flexibility to the power system. However, flexibility utilization also introduces new challenges to distribution system operators (DSOs), who need mechanisms to supervise flexibility activations and monitor their effect on distribution network operation. Flexibility activations can be broadly categorized to those originating from electricity markets and those initiated by the DSO to avoid constraint violations. Simultaneous electricity market driven flexibility activations may cause voltage quality or temporary overloading issues, and the failure of flexibility activations initiated by the DSO might leave critical grid states unresolved. This work proposes a novel data processing pipeline for automated real-time identification of fast-ramped flexibility activation events. Its practical value is twofold: i) potentially critical flexibility activations originating from electricity markets can be detected by the DSO at an early stage, and ii) successful activation of DSO-requested flexibility can be verified by the operator. In both cases the increased awareness would allow the DSO to take counteractions to avoid potentially critical grid situations. The proposed pipeline combines techniques from unsupervised detection and open-set classification. For both building blocks feasibility is systematically evaluated and proofed on real load and flexibility activation data.

An Analysis of the North Carolina Nursing Home Polypharmacy Initiative
Creators: name: Trygstad, Troy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This dissertation is an evaluation of the North Carolina Polypharmacy Initiative (Initiative). The Initiative was a demonstration project that remunerated nursing home consultant pharmacists for value-added drug regimen reviews using a claims-generated patient profile that flagged targeted drugs and drug classes for review. Shewhart's PDSA (Plan-Do-Study-Act) cycle is used as the framework to guide this evaluation. The Initiative brought about three distinct PDSA cycles throughout its history. The first was the pilot project, and the second was a statewide endeavor, while the third continues through other programs and settings in North Carolina. It is the goal of this dissertation to inform the planning stage of future PDSA cycles of pharmacist services in nursing home settings. Three formal evaluations of the initiative were conducted. The first evaluation, a before-after without comparison group study found a per member per month (PMPM) drug cost savings of $30.33 due to initiative activities. The second, a before-after with comparison group study found a PMPM drug cost savings of $19.04. The third, a beforeafter with propensity matched comparison group found a PMPM drug cost savings of $21.36. Flags (alerts) were reduced for two types of alert categories across all evaluations and their sub-group evaluations. The first, alerts for drugs on the Prescription Advantage List (PAL) iv were substantially reduced with a percentage reduction of 19.2% for all persons having a pharmacist review. The PAL list a voluntary preferred drug list sponsored by North Carolina Medicaid. The second, alerts for drugs on the Clinical Initiatives List were also substantially reduced with a percentage reduction of 9.6% for all residents having a pharmacist review. The Clinical Initiatives List was a list of drugs submitted by consultant pharmacy organizations that were targeted for cost-effectiveness and quality concerns. Overall, Phases 1, 2 and 3 of the Initiative produced consultant pharmacist reviews for 19,144 nursing home residents. These reviews generated 17,545 recommendations that resulted in greater than 10,000 drug changes. Findings from this dissertation support the conclusion that a targeted program using pharmacists to review patient profiles may be quickly launched and expeditiously conducted across large numbers of patients, at least in long-term-care settings.

description: In dieser Arbeit wird unter Verwendung des Su-Schrieffer-Heeger-Modells die Dynamik des einfachsten konjugierten Polymers Trans-Polyacetylen in Mean-Field-Approximation untersucht. Dazu wird erstmalig von einer dimerisierten Peierls-Kette im Grundzustand ausgegangen, die durch einen gaußförmigen Laserpuls angeregt wird. Sowohl bei subresonanter Anregung als auch bei Anregungen hoch im Band bilden sich geladene Solitonpaare mit gemischten Gap-Zuständen, für die ein Phasendiagramm in Abhängigkeit vom Mischungsparameter abgeleitet wird. Diese Zustände werden im Rahmen des Takayama-Lin-Liu-Maki-Modells erfolgreich beschrieben.Um einen Ladungstransfer zwischen benachbarten Ketten zu untersuchen, werden die Rechnungen auf zwei gekoppelte Peierls-Ketten ausgedehnt. In Abhängigkeit von der Kopplungsstärke und der Kettenlänge ergibt sich eine Reihe von Grundzustandskonfigurationen. Bei einer Anregung mit einem transversalen Laserpuls findet ein Ladungstransfer zwischen den beiden Ketten mit einer Frequenz statt, die der doppelten Kopplungsstärke entspricht. Zur Einbeziehung der Coulomb-Wechselwirkung der Pi-Elektronen wird das Pariser-Parr-Pople-Modell verwendet. Durch Anpassung an möglichst viele experimentelle Größen wird ein geeigneter Satz von Modell-Parametern berechnet. Die von der Kette aufgenommene Energie und deren Dynamik werden diskutiert.
description: In the framework of the Su-Schrieffer-Heeger model the dynamics of the most simple conjugated polymer trans-polyacetylene is investigated in mean field approximation. Starting with a dimerized Peierls chain in the ground state, a femtosecond laser pulse with a gaussian enveloppe is applied. For subresonant and high band excitation charged soliton pairs are created and are related to mixed gap states. For different values of the mixing strength a phase diagram can be drawn. The creation of the mixed gap states can be also explained within the continuum approximation with the Takayama-Lin-Liu-Maki model. In order to investigate charge transfer between two Peierls chains, the calculations are extended to a system with two coupled chains. Different ground state configurations occur, depending on the coupling stength and the chain length. In the case of an excitation perpendicular to the chain axis, a strong charge transfer between the chains is observed. Furthermore the Pariser-Parr-Pople model is used to take into account the Coulomb interaction between the Pi-electrons. A model parameter set can be determined by fitting the experimental values. The energy absorbed by the chain and the soliton dynamics are discussed in this model.
Products of Eisenstein series and Fourier expansions of modular forms at cusps

description: We show, for levels of the form $N = p^a q^b N'$ with $N'$ squarefree, that in weights $k \geq 4$ every cusp form $f \in \mathcal{S}_k(N)$ is a linear combination of products of certain Eisenstein series of lower weight. In weight $k=2$ we show that the forms $f$ which can be obtained in this way are precisely those in the subspace generated by eigenforms $g$ with $L(g, 1) \neq 0$. As an application of such representations of modular forms we can calculate Fourier expansions of modular forms at arbitrary cusps and we give several examples of such expansions in the last section.
description: This is an update to a previous version of the article. In the new version we describe an algorithm (available at https://github.com/michaelneururer/products-of-eisenstein-series) that computes Fourier expansions at cusps

Data were collected from 445 among older Greek exercise participants who were exercising in either individual activities or group-based indoor exercise programs. Confirmatory factor analysis supported the hypothesized correlated five-factor structure of BREQ-2 responses. All BREQ-2 subscales had adequate internal reliability assessed via composite reliability indexes, average variance extracted, and Cronbach’s α coefficients. Further, nomological validity of BREQ-2 responses was also supported.

Identifying the determinants of coexisting over and undernutrition in Cebu, Philippines

description: Obesity has quickly become a worldwide epidemic. Unlike in developed countries, in developing countries obesity is rapidly on the rise while chronic undernutrition remains a pervasive problem. This situation is only further complicated by the finding that over and undernutrition overlap so that in many cases both forms of malnutrition co-occur in the same communities and even households. However, developing countries do not have the healthcare infrastructure, nor do a majority of individuals have the financial means to counteract the negative impact of chronic undernutrition or obesity and its associated chronic diseases. Several studies have identified that there is a divergence of weight status between adults and offspring in countries experiencing rapid modernization but no studies that we know of have explored possible differential weight-related behavior patterns that might explain this difference. This research investigates key factors characterizing discrepant weight mother-offspring pairs in the rapidly transitioning society of Cebu, Philippines. In addition, this research identifies key determinants of diet and physical activity patterns of Filipino mothers and offspring in respond to modernization, including an evaluation of possible generational differences. We used data from multiples years of the Cebu Longitudinal Health and Nutrition Survey. Detailed individual, household, and community-level environmental, socioeconomic, and demographic information was collected at each survey year, which allowed for an exploration of the association between multiple dimensions of modernization and multiple dimensions of physical activity and diet. Specifically, in this research we identified the urbanicity and socioeconomic (SES) environment where discrepant overweight mother/underweight offspring pairs were most commonly found and explored participation in weight-related behaviors by offspring that might contribute to this dual-burden phenomenon. Second, we explored the impact of urbanicity and SES on the dietary patterns in energy adequacy, percent calories from fat and carbohydrates of mothers compared to offspring over time. Finally, we explored the association of urbanicity and SES with occupational, chores and leisure physical activity of mothers and offspring at multiple times points. This research addresses an important gap in understanding generational differences in weight-related behavior responses to modernization; knowledge necessary to develop effective age and weight-status specific interventions in transitional societies.

description: We explore the breaking of Lorentz and CPT invariance in strong interactions at low energy in the framework of chiral perturbation theory. Starting from the set of Lorentz-violating operators of mass-dimension five with quark and gluon fields, we construct the effective chiral Lagrangian with hadronic and electromagnetic interactions induced by these operators. We develop the power-counting scheme and discuss loop diagrams and the one-pion-exchange nucleon-nucleon potential. The effective chiral Lagrangian is the basis for calculations of low-energy observables with hadronic degrees of freedom. As examples, we consider clock-comparison experiments with nuclei and spin-precession experiments with nucleons in storage rings. We derive strict limits on the dimension-five tensors that quantify Lorentz and CPT violation.

description: In dieser Dissertation versuche ich, die zentralen Nitrogen-heterocyclischen Kerne, die Seitenketten und deren Position zu variieren. Als synthetische Strategie wurden Palladium-katalysierte Kupplungsreaktionen verwendet, um Seitenketten und Aryl-Substituenten einzuführen. Halogensubstituierte Diarylheterocyclen sind wichtige Intermediate in der Synthese der allgemeine Strukture. Die Einführung der gewünschten Seitenketten durch Carbon-Carbon und Carbon-Nitrogen-Bindungsknüpfung wurde durch Sonogashira-Kupplung, Heck-Kupplung und Buchwald-Hartwig-Aminierung erzielt. Mit der Sonogashira-Reaktion kann eine funktionalisierte Alkynylgruppe in die heterocyclischen Kerne effektiv und bequem eingeführt werden. Eine anschliessende katalytische Hydrierung der Alkynylgruppe führt zu funktionalisierten Alkyl substituierten Diarylheterocyclen. In der vorliegenden Arbeit wurden mehr als 180 Substanzen synthetisiert. Unter ihnen sind ungefähr 130 neue Substanzen. 86 von ihnen passen in die allgemeine Strukture.
description: In the present thesis, I tried to vary the central nitrogen-heterocyclic cores, the functionalised side chains and its position of attachment. As a synthetic strategy, palladium-catalyzed coupling reactions were used to introduce side chains and aryl substituents into the central heterocycle. In this way the utility of such reactions to heterocyclic systems, which were neglected so far, could be figured out. Halogen substituted diaryl heterocycles are important intermediates in the synthesis of general structures. The introduction of the desired side chains by Carbon-Carbon bond formation reactions was achieved by Sonogashira coupling and Heck coupling. Buchwald-Hartwig amination and nucleophilic substitution were used to establish side chains which are connected to the core heterocycle by heteroatom-Carbon bonds. Sonogashira reaction turned out to be the most effective and convenient method to introduce functionalized alkynyl group into the heterocyclic cores. In the present work, more than 180 compounds were synthesized. Among them, about 130 compounds are new products. 86 of them fit into the general structure.

description: Η παρούσα εργασία αποτελεί σχολιασμένη μετάφραση από την αγγλική προς την ελληνική γλώσσα αποσπασμάτων του άρθρου με τίτλο “Sex- or Gender-specific Differences in the Clinical Presentation, Outcome, and Treatment of SARS-CoV-2” που δημοσιεύτηκε στο περιοδικό “Clinical Therapeutics”. Στο άρθρο περιγράφονται οι διαφορές μεταξύ ανδρών και γυναικών ως προς την κλινική εικόνα, τη θεραπεία και την έκβαση της λοίμωξης από SARS-CoV-2, οι οποίες εξετάζονται υπό το πρίσμα τόσο του βιολογικού (biological sex), όσο και του κοινωνικού φύλου (gender). Στο πρώτο μέρος της εργασίας πραγματοποιείται η γλωσσική και κειμενική ανάλυση του κειμένου-πηγή. Επίσης, αναλύονται οι λόγοι για τους οποίους επιλέχθηκε το συγκεκριμένο άρθρο, οι οποίοι αφορούν κυρίως τον διεπιστημονικό χαρακτήρα του, καθώς στο κείμενο συνυπάρχουν ιατρικοί όροι και όροι του πεδίου των σπουδών φύλου. Στη συνέχεια, παρατίθεται η μετάφραση των αποσπασμάτων, και ακολουθεί το γλωσσάρι με τους όρους και την τεκμηρίωσή τους. Τέλος, παρουσιάζονται τα κυριότερα προβλήματα που προέκυψαν κατά τη μεταφραστική διαδικασία.
description: This paper is an annotated translation from English into Greek of excerpts from the article entitled “Sex- or Gender-specific Differences in the Clinical Presentation, Outcome, and Treatment of SARS-CoV-2” published in the journal “Clinical Therapeutics”. The purpose of the article is to describe the differences between men and women in terms of the clinical presentation, treatment, and outcome of SARS-CoV-2 infection. These differences are examined in terms of both biological sex and gender. In the first section of the paper, a linguistic and textual analysis of the source text is carried out. Furthermore, the reasons that led to the choice of this particular article are analyzed, which mainly concern its interdisciplinary nature, since medical terms and terms from the field of gender studies coexist in the text. The translation of the excerpts is then provided, followed by a glossary of terms and their documentation. Finally, the main problems encountered during the translation process are presented.
Rotaxane mit photochemisch steuerbarer Translation des Makrozyklus

description: Neuartige Rotaxane, die zwei 9-Aryl-9-methoxy-10-methyl-9,10-dihydroacridin-Bausteine (Acridane) an beiden Enden der molekularen Achse als Bindungsstellen für den tetrakationischen CBPQT4+-Ring besitzen, wurden gemeinsam mit ihren korrespondierende Acridinium-Rotaxanen synthetisiert. Mit diesen Rotaxanen wurde ein neues Konzept für die Steuerung der Ringbewegung im Rotaxan realisiert. Aufgrund der Brownschen Molekularbewegung pendelt der Ring von einem Ende der Achse zur anderen in den Acridan-Rotaxanen. Diese Pendelbewegung wird durch die Umwandlung von einer oder zwei Acridan-Stationen in die entsprechende Acridinium-Einheit gestoppt. Wenn beide Acridane durch Zugabe von Säure umgewandelt werden, komplexiert der Ring auf einer Ausweich-Station, die im mitlleren Bereich der Achse zu finden ist. Durch Photonen wird nur die unbesetzte Acridanstation umgewandelt, so dass der Ring auf der unveränderten Acridan-Station verbleibt. Die Pendelbewegung kann wieder durch Zugabe von Base und durch thermische Rückreaktion des Methoxids mit dem gebildeten Acridinium-Ion angeschaltet werden.
description: Novel rotaxanes containing two 9-aryl-9-methoxy-10-methyl-9,10-dihydroacridine moieties (acridanes) at both ends at the molecular axle as recognition stations for the tetracationic ring CBPQT4+ were synthesized together with their acridinium counterparts. A new concept of controlling the ring movement within rotaxanes has been realized with these rotaxanes. Owing to Brownian molecular movement, the ring shuttles from one end of the axle to the other one in acridane rotaxanes. The shuttle process is stopped by converting two or one of the acridane stations into the corresponding acridinium unit. If both acridanes are transformed by addition of an acid, the ring resides on evasive stations present in the center of the axle. Photons convert only the unoccupied acridane station, thus the ring remains on the unchanged acridane station. The shuttle process can be switched on by addition of a base and by thermal reaction of the methoxide with the formed acridinium ion, respectively.
