Full textMenggwa Dla is a Papuan language spoken in Sandaun Province of Papua New Guinea and Kabupaten Jayapura of Papua Province, Indonesia. Menggwa Dla is a dialect of the Dla language; together with its sister language Anggor (e.g. Litteral 1980), the two languages form the Senagi language family, one of the small Papuan language families found in North-Central New Guinea. The main text of this thesis is divided into seven chapters. Chapter 1 introduces the linguistic, cultural and political landscapes of the Indonesia-Papua New Guinea border area where the Dla territory is located. Chapter 2 introduces the phonology of Menggwa Dla; described in this chapter are the phonemes, allophonic variations, phonotactics, morpho-phonological processes, stress assignment and intonation of the language. The inventory of phonemes in Menggwa is average for a Papuan language (15 consonants and 5 vowels). The vast majority of syllables come in the shape of V, CV or C1C2V where C2 can be /n/ /r/ /l/ /j/ or /w/. In C1C2V syllables, the sonority rises from C1 to V (§2.2.2). Nevertheless, there are a few words with word-medial consonant sequences like ft /ɸt/, lk /lk/, lf /lɸ/ or lk /lk/ where the sonority drops from the first to the second consonant; the first consonant in these sequences is analysed as the coda of the previous syllable (§2.2.3). Chapter 3 is an overview of the word classes in Menggwa Dla; the morphological, syntactic and semantic properties of the three major word classes (nouns, adjectives and verbs) and the minor word classes are compared in this chapter. Chapter 4 describes the properties of nouns and noun phrases; the person-number-gender categories, noun-phrasal syntax, nominal clitics and personal pronouns are outlined in this chapter. Menggwa Dla has a rich array of case, topic and focus markers which comes in the form of clitics (§4.5). Subject pronouns (‘citation pronouns’) only mark person (i.e. one for each of the three persons), whereas object and genitive pronouns mark person (including inclusive/exclusive first person), number, and sometimes also gender features (§4.6). Chapter 5 introduces various morphological and syntactic issues which are common to both independent and dependent clauses: verb stems, verb classes, cross-referencing, intraclausal syntax, syntactic transitivity and semantic valence. Cross-referencing in Menggwa Dla is complex: there are seven paradigms of subject cross-reference suffixes and four paradigms of object cross-references. Based on their cross-referencing patterns, verbs are classified into one of five verb classes (§5.2). There is often a mismatch between the number of cross-reference suffixes, the semantic valence, and the syntactic transitivity within a clause. There are verbs where the subject cross-reference suffix, or the object suffix, or both the subject and object suffixes are semantically empty (‘dummy cross-reference suffixes’; §5.3.2). Chapter 6 outlines the morphology of independent verbs and copulas. Verbal morphology differs greatly between the three statuses of realis, semi-realis and irrealis; a section is devoted to the morphology for each of the three statuses. Chapter 7 introduces the dependent clauses and verbal noun phrases. Different types of dependent verbs are deverbalised to various degrees: subordinate verbs are the least deverbalised, chain verbs are more deverbalised (but they mark switch-reference (SR), and sometimes also interclausal temporal relations), and non-finite chain verbs even more deverbalised. Further deverbalised than the non-finite chain verbs are the verbal nouns; verbal noun phrases in Menggwa Dla functions somewhat like complement clauses in English. In younger speakers speech, the function of the chain clause SR system has diverted from the canonical SR system used by older speakers (§7.2.2). For younger speakers, coreferential chain verb forms and disjoint-reference chain verb forms only have their coreferential and disjoint-referential meaning — respectively — when the person-number-gender features of the two subject cross-reference suffixes cannot resolve the referentiality of the two subjects. Otherwise, the coreferential chain verb forms have become the unmarked SR-neutral chain verb forms. At the end of this thesis are appendix 1, which contains four Menggwa Dla example texts, and appendix 2, which contains tables of cross-reference suffixes, pronouns, copulas and irregular verbs.

Full textThis thesis deals with two kinds of statistical mechanics problems: percolation ongroups and directed models. In the first case, we realise the group under considerationas a geometric object (via the notion of Cayley graph) before breaking it apartrandomly. The study of this process reveals deep connections between the geometricproperties of a group and the behaviour of Bernoulli percolation on it. In the secondcase, we focus on models where up and down play different roles, which makes severalquestions less hard to tackle.Chapter 1 strengthens the Indistinguishability Theorem of Lyons-Schramm, whichstates that the infinite clusters yielded by a Bernoulli percolation on a Cayley graphalmost surely all look alike. The non-Triviality of this strengthening is illustrated bya directed model that satisfies the Indistinguishability Property but not the StrongIndistinguishability Property.Chapter 2 has been obtained in collaboration with Vincent Tassion. We show thatthe value of the critical parameter for Bernoulli percolation essentially only dependson the local structure of the considered abelian Cayley graph.In Chapter 3, we introduce a directed version of the DLA model, for which weestablish the existence of an infinite volume dynamics, control the propagation ofinformation and prove asymptotic inequalities on the width and height of the cluster

Full textThe International Military Tribunal for the Far East, also known as a Tokyo Tribunal, was the second institution of its kind in the world, established in order to bring to justice the most important representatives of the Empire of Japan for starting the Second World War in the Far East and for the war crimes committed in its duration. It was the first time in history when for the breaches of the international law, formally being the acts of a nation, the responsibility was placed on country’s leaders. Despite the importance of Tokyo Tribunal for the international criminal law and the still visible consequences of the 1948 judgement, it is recalled merely as an appendix to the International Military Tribunal in Nuremberg. Grave issues concerning the procedure, linguistic problems, different aims of the eleven world powers represented in Japan and the charges of retroactivity set the stage for criticism of the trial in Tokyo, labelling it as an example of “victors’ justice”.

This dissertation analyses the gauge field sector for the quantum electrodynamics with electric and magnetic currents. It uses the Zwanziger model with two independent gauge field potentials and . The assumption that the electric and magnetic currents have the same transformation properties, effectively leads to the and symmetry breaking, while the composed transformation or generally recovers the symmetry of the system. The properties of two-point Wightman functions, i.e. the vacuum expectations values of the unordered product two gauge field operators, were intensively studied. The general form of the diagonal Wightman functions and is found for different choices of gauge fixing conditions - it has a symmetrical form and includes the invariant part proportional to . Furthermore, the differential equation has been found for the mixed Wightman functions . It is shown that this equation has no Lorentz covariant solution. But the spherically symmetric solution has been found and it corresponds to the Coulomb gauge condition - this is proven by the canonical quantization procedure for systems with constraints - the Dirac method. For other gauge conditions: planar, light cone gauge in end direction, the canonical quantization procedure is carried out within the simplified procedure - the Faddeev-Jackiw method. The Wightman functions for the gauge field potentials are found and they are consistent with general formulas derived before. Also the gauge dependent parts are explicitly given for different gauge fixing conditions.

Full textIn my dissertation I investigate the relations between philosophy and literature. In the preface I present the ,,ancient quarell” between philosophy and poetry. I claim that both disciplines constitute each other. I pose the questions which in futher parts of my work I will try to answer: is there a point today in the division between philosophy and literature? Can they – in spite of diagnosis of crisis in both fields – inspire each other? And what is the relation between the form and the contents, how does the philosophical or literary style determine things that we can say by the means of it? I also recall the fundamental question that Stanley Cavell poses in the end of his book The Claim of Reason that is ,,can philosophy become literature and still know itself?”. In the first chapter I discuss the views of Richard Rorty. I analyze his critique of philosophy by capital ,,P”, his revolutionary claims about metaphor and above all his project of liberal utopia presented in Contigngency, Irony and Solidarity. I pursue in detail the role of literature in his project and the advantages and risks of Rorty's irony. In the second chapter I present the figure of Harold Bloom. Although Bloom is not a philosopher, but a literary ctitic, and he doesn't like or value philosophy, his conception provokes philosophical interpretation. I analyze his notion of anxiety of influence and the condition of beletedness which according to him characterizes the situation of all modern poets and all participants of modern culture. I present six revisionary ratio, by means which the young poet defendes himself against his precursor. I pursue Bloom's stance in the quarell between philosophy and literature. Then – a little bit perversely – I try to track down Bloom's own precursors. In the third chapter I pursue the orginal and interdisciplinary writings of Stanley Cavell. Their central issue is the problem of scepticism. I analyze in detail his so-called “truth of the moral” about scepticism and his claim that Wittgenstein didn't manage to refute scepticism. Then I discuss his very interesting interpretation of Shakespeare's tragedy. In the end of this chapter I wonder if Cavell – despite his interdisciplinary stance – advocates the merger of philosophy and literature. In the fourth an last chapter, I pursue the problem of Romanticism. I present the history of German and British romanticism. Following the footsteps of Agata Bielik-Robson I try to show that Romanticism elaboreted the extremly orginal philosophy, which still demands a critical revision, whereas romantic claim to merge philosophy and literature still demands realisation. In the end I gather the conclusions to discover that for Rorty the division between philosophy and literature does not make sense, and for Bloom –hovever he poses himself on the side of poetry – this division is also bluring, Cavell on the other hand holds to that distinction. I also claim that the form of expression does effect the content being communicated. I reach the conclusion that both disciplines should inspire each other and that philosophy needs literature more than literature needs philosophy. In the end I answer positively Stanley's Cavell's question whether philosophy can become literature and still know itself.

Full textThe experiments described in this dissertation involves the study of the graphene oxide synthesis and reduction by chemical or electrochemical methods in order to use the resulting material as a substrate for laccase (Lac) and horseradish peroxidase (HRP). Before and after the electroreduction graphene oxide has been tested for functional group content, morphology and the ability to be used with the immobilized enzyme as an electrode. The basic techniques used in this study were voltammetric techniques, supported by results from infrared microscopy with Fourier Transform (FTIR). Changes in the structure and morphology of the surface were visualized using electron microscopy and X-ray energy dispersive spectroscopy (EDS). In terms of the study I can distinguish four leading issues: - graphene oxide synthesis by the modified Hummer-Offeman method; - development of effective method for reducing graphene oxide that allows to obtain structures from a few to several layers of graphene with a content of oxygen functional groups; - conditioning graphene oxide in ammonia water (NH3 aq) in order to introduce the nitrogen surface groups onto the graphene layers; - preparation of electrodes based on graphene oxide and reduced graphene oxide with immobilized redox enzyme and study the suitability of those electrodes to function as a biosensor. In the first part of thesis, oxidation of graphite was tested for the introduction of oxygen-containing groups into the spaces between the graphene layers. For this purpose, modified Hummer-Offeman method of synthesis was used. The obtained product was analyzed by infrared spectroscopy technique and X-ray energy dispersive spectroscopy (EDS). These studies were performed to assess the oxygen content in the material and to determine the participation of oxygen functional groups. To diagnose changes in the morphology of graphene layers before and after oxidation transmission and scanning electron microscopy was used. The second part of the thesis contains the description of reducing process of graphene oxide by using chemical and electrochemical methods. Graphene oxide was treated with a chemical reducing substance or was reduced by voltammetric methods. The loss of oxygen and the changes of the structure were examined by techniques such as infrared microscopy and electron microscopy. In this part of the thesis, method of controlling the amount of oxygen functional groups on the surface of graphene oxide, has been developed by supervising the stages of electrochemical reduction. The third part of the dissertation refers to the introduction of the nitrogen functional groups onto the surface of graphene layers by conditioning graphene oxide in ammonia water (NH3 aq). Conditioned graphene oxide, due to the presence of electroactive nitrogen groups on the surface of layers, exhibited catalytic activity during reduction of hydrogen peroxide (H2O2). Introduction and analysis of the nitrogen functional groups on the surface of the graphene oxide allowed to assess the significance and usefulness of graphene oxide conditioned in ammonia water (NH3 aq) in the construction of chemical sensors. In addition, the durability of conditioned graphene oxide layers was analyzed. The fourth issue, considered in the dissertation, refers to the use of the prepared layers of graphene oxide and reduced graphene oxide as a base for the immobilization of enzymes: laccase (Lac) or horseradish peroxidase (HRP). These enzymes catalyze, respectively: laccase – reduction of oxygen (O2), horseradish peroxidase – reduction of hydrogen peroxide (H2O2). Electrocatalytic properties of immobilized enzymes were studied using voltammetric and chronoamperometric methods to determine the sensitivity relative to the analyte and possible applications in biosensors. Current and potential values of the analyte reduction were a measure of the electrocatalytic properties. Particular attention was given to two types of systems. First system had reduced graphene oxide layers as a matrix on which laccase (Lac) was immobilized. This system occurred to exhibit direct electron transfer during the reduction of molecular oxygen (O2). Second system was electrically active during the reduction of hydrogen peroxide (H2O2) and was based on reduced graphene oxide conditioned in ammonia water (NH3 aq) with bounded horseradish peroxidase (HRP).
Kopiński, Jarosław. "Nierówność Penrose'a dla zaburzonych danych początkowych Schwarzschilda." Doctoral thesis, 2020. https://depotuw.ceon.pl/handle/item/3738.
Full textThe Penrose inequality is a lower bound on the mass of the spacetime in terms of surface area of the event horizons of black holes. According to the belief that any solution of the Einstein field equations which describe those objects will eventually settle down to the Kerr metric this relation should also hold on an initial hypersurface. This is a straightforward consequence of laws of black holes thermodynamics and the fact that because of the radiation the mass does not increase during the evolution. If the considered initial data is axisymmetric the similar argument leads to the generalized inequality with the angular momentum. Both versions of this relation have the rigidity statements, according to which it is saturated in Schwarzschild and Kerr spacetimes, respectively. Despite multiple arguments in favor of the Penrose inequality, its proof has only been presented for the special case of initial data which is strictly connected with the timesymmetric hypersurface. This thesis is devoted to the verification of the Penrose inequality with angular momentum for vacuum axisymmetric perturbations of the Schwarzschild initial data with the spherical inner boundary. They are obtained with the use of conformal method, which allows to prescribe the location of the marginally outer trapped surface in the natural way. The assumption about the axial Killing vector is dictated by the fact that the momentum constraint can be then solved in terms of scalar potentials, which define the relevant quantities and allow for an easy estimate of the difference of their values. The main result of this thesis is the verification of the Penrose inequality for the maximal and non-CMC perturbations. It is satisfied in the leading order of expansion with respect to the parameter measuring the deviation from Schwarzschild data in both cases, apart from the special (nongeneric) data, where the higher order terms have to be included to yield a proper estimate. Because of the complexity of this endeavour it has been done only for the maximal hypersurface. In this setting the inequality is satisfied up to fourth order of expansion for the generalized Bowen-York extrinsic curvature. This result has also been confirmed with the use of numerical solution of constraint equations with the nonvanishing linear and angular momentum.
