  abstract  = {Magnetorotational instability (MRI) is one of the most important and most common instabilities in astrophysics. Today it is widely accepted that it serves as a major source of turbulent viscosity in accretion disks, the most energy efficient objects in the universe. The importance of the MRI for astrophysics has been realized only in recent fifteen years. However, originally it was discovered much earlier, in 1959, in a very different context. Theoretical flow of a conducting liquid confined between differentially rotating cylinders in the presence of an external magnetic field was analyzed. The central conclusion is that the additional magnetic field parallel to the axis of rotation can destabilize otherwise stable flow. Theory of non-magnetized fluid motion between rotating cylinders has much longer history, though. It has been studied already in 1888 and today such setup is usually referred as a Taylor-Couette flow. To prove experimentally the existence of MRI in a magnetized Taylor-Couette flow is a demanding task and different MHD groups around the world try to achieve it. The main problem lies in the fact that laboratory liquid metals which are used in such experiments are characterized by small magnetic Prandtl number. Consequently rotation rates of the cylinders must be extremely large and vast amount of technical problems emerge. One of the most important difficulties is an influence of plates enclosing the cylinders in any experiment. For fast rotation the plates tend to dominate the whole flow and the MRI can not be observed. In this thesis we discuss a special helical configuration of the applied magnetic field which allows the critical rotation rates to be much smaller. If only the axial magnetic field is present, the cylinders must rotate with angular velocities corresponding to Reynolds numbers of order Re ≈ 10^6. With the helical field this number is dramatically reduced to Re ≈ 10^3. The azimuthal component of the magnetic field can be easily generated by letting an electric current through the axis of rotation, In a Taylor-Couette flow the (primary) instability manifests itself as Taylor vortices. The specific geometry of the helical magnetic field leads to a traveling wave solution and the vortices are drifting in a direction determined by rotation and the magnetic field. In an idealized study for infinitely long cylinders this is not a problem. However, if the cylinders have finite length and are bounded vertically by the plates the situation is different. In this dissertation it is shown, with use of numerical methods, that the traveling wave solution also exists for MHD Taylor-Couette flow at finite aspect ratio H/D, H being height of the cylinders, D width of the gap between them. The nonlinear simulations provide amplitudes of fluid velocity which are helpful in designing an experiment. Although the plates disturb the flow, parameters like the drift velocity indicate that the helical MRI operates in this case. The idea of the helical MRI was implemented in a very recent experiment PROMISE. The results provided, for the first time, an evidence that the (helical) MRI indeed exists. Nevertheless, the influence of the vertical endplates was evident and the experiment can be, in principle, improved. Exemplary methods of reduction of the end-effect are here proposed. Near the vertical boundaries develops an Ekman-Hartmann layer. Study of this layer for the MHD Taylor-Couette system as well as its impact on the global flow properties is presented. It is shown that the plates, especially if they are conducting, can disturb the flow far more then previously thought also for relatively slow rotation rates.},

  abstract  = {Luminous Blue Variables show strong changes in their stellar wind on time scales of typically years to decades when they expand and contract radially at approximately constant luminosity. Micro-variability on shorter time scales and amplitudes can be observed superimposed to the larger scale radial changes. I will show long-term time series of high resolution spectra which we have collected in the past 20 years for many of the well known LBVs together with a few time series of weekly sampling (HR Car, R40, R71, R110, R127, S Dor) covering a time windows of up to a few months. Wind variability is seen on short and intermediate time scales with the line profiles changing from P Cygni to inverse P Cygni and double peeked profiles sometimes for the same star and spectral line. On longer time scales the ionisation levels for all chemical elements change drastically due to the strong change of the temperature on the stellar surface. While on the long term the characteristic radial changes may have impact on the over all mass loss rates, the variabilities and asymmetries on short and intermediate time scales may cause false estimates of the mass loss rates when confronting models with the observed line profiles},

  abstract  = {The solar tachocline is a thin transition layer between the solar radiative zone rotating uniformly and the solar convection zone, which has a mainly latitudinal differential rotation profile. This layer has a thickness of less than \$0.05R_{\sun}\$ and is subject to extreme radial as well as latitudinal shears. Helioseismological estimates put this layer at roughly \$0.7R_{\sun}\$. The tachocline mostly resides in the sub-adiabatic, non-turbulent radiative interior, except for a small overlap with the convection zone on the top. Many proposed dynamo mechanisms involve strong toroidal magnetic fields in this transition region. The exact mechanisms behind the formation of such a thin layer is still disputed. A very plausible mechanism is the one involving a weak, relic poloidal magnetic field trapped inside the radiative zone, which is responsible for expelling differential rotation outwards. This was first proposed by \citet{RK97}. The present work develops this idea with numerical simulations including additional effects like meridional circulation. It is shown that a relic field of 1~Gauss or smaller would be sufficient to explain the observed thickness of the tachocline. The stability of the solar tachocline is addressed as the next part of the problem. It is shown that the tachocline is stable up to a differential rotation of 52\\% in the absence of magnetic fields. This is a new finding as compared to the earlier two dimensional models which estimated the solar differential rotation (about 28\\%) to be marginally stable or even unstable. The changed stability limit is attributed to the changed stability criterion of the 3-dimensional model which also involves radial gradients of the angular velocity. In the presence of toroidal magnetic field belts, the lowest non-axisymmetric mode is shown to be the most unstable one for the radiative part of the tachocline. It is estimated that the tachocline would become unstable for toroidal fields exceeding about 100~Gauss. With both formation and stability questions satisfactorily addressed, this work presents the most comprehensive analysis of the physical processes in the solar tachocline to date.},

  abstract  = {Extract: [...]The Roman conquest of what was to become the province of Gallia Narbonensis in the second and then of the whole of Transalpine Gaul in the first century B.C. led to the incorporation into the Roman empire of a large part of the territory in which Gaulish was then spoken.1 In consequence, the vernacular rapidly lost its footing at least in public life and was soon replaced by Latin, the language of the new masters, which enjoyed higher prestige (cf. e.g. Meid 1980: 7-8). On the other hand, Gaulish continued to be written for some three centuries and was probably used in speech even longer, especially in rural areas. We must therefore posit a prolonged period of bilingualism. The effects of this situation on the Latin spoken in the provinces of Gaul seem to have been rather limited. A number of lexical items, mostly from the field of everyday life, and some phonetic characteristics are the sole testimonies of a Gaulish substratum in the variety of Latin that was later to develop into the Romance dialects of France (cf. Meid 1980: 38, fn. 77). [...]},

  abstract  = {Wasserdampf in der Stratosph{\"a}re und Troposph{\"a}re ist eines der wichtigsten atmosph{\"a}rischen Treibhausgase. Neben seiner Bedeutung f{\"u}r das Klima hat es großen Einfluss auf die Bildung von polaren stratosph{\"a}rischen Wolken sowie auf die atmosph{\"a}rische Chemie. Weltweit erstmalig soll innerhalb eines Forscherverbundes in Deutschland ein leistungsstarkes, mobiles, abtastendes Wasserdampf-DIAL zur dreidimensional hochaufgel{\"o}sten Messung des atmosph{\"a}rischen Wasserdampfs entwickelt werden. Mit dem Wasserdampf-DIAL k{\"o}nnen Wasserdampfkonzentrationen in der Atmosph{\"a}re mit hoher zeitlicher und r{\"a}umlicher Aufl{\"o}sung gemessen werden. Das DIAL basiert auf einem Titan-Saphir-Laser oder einem dazu alternativen OPO-Laser (optisch parametrischer Oszillator). Der f{\"u}r das optische Pumpen dieser Laser n{\"o}tige Pumplaser wurde im Rahmen dieser Arbeit in der Arbeitsgruppe Nichtlineare Optik des Instituts f{\"u}r Physik der Universit{\"a}t Potsdam entwickelt. Ein hochaufl{\"o}sendes, mobiles DIAL erfordert einen Pumplaser mit großen Pulsenergien, guter Strahlqualit{\"a}t und einer hohen Effizienz. Um diese Ziele zu erreichen, wurde ein MOPA-System (Master Oscillator Power Amplifier) mit Frequenzstabilisierung auf der Basis von doppelbrechungskompensierten, transversal diodengepumpten Laserst{\"a}ben entwickelt und untersucht. Auf dem Weg dahin wurden unterschiedliche Realisierungsm{\"o}glichkeiten des MOPA-Systems gepr{\"u}ft. Im Rahmen dessen wurden die Festk{\"o}rperlasermaterialien Yb:YAG [1], kerndotierte Nd:YAG-Keramik [2] und herk{\"o}mmliches Nd:YAG vorgestellt und hinsichtlich ihrer Eignung f{\"u}r dieses MOPA-System untersucht. Nachdem die Entscheidung f{\"u}r Nd:YAG als laseraktives Material gefallen war, konnte darauf aufbauend die Konzeptionierung des Lasersystems auf der Basis von Verst{\"a}rkungsrechnungen vorgenommen werden. Die entwickelte Verst{\"a}rkungsrechnung tr{\"a}gt den Tatbest{\"a}nden von realen Systemen Rechnung, indem radiusabh{\"a}ngige Intensit{\"a}ten und eine radiale, nicht homogene Inversionsdichte ber{\"u}cksichtigt werden. Die Frequenzstabilisierung des gepulsten Oszillators (Frequenzstabilit{\"a}t von 1 MHz) wurde mittels des Pound-Drever-Hall-Verfahrens vorgenommen. Mit der Heterodynmethode wird die Frequenzstabilit{\"a}t des Oszillators gemessen. Nach Untersuchungen {\"u}ber verschiedene Konfigurationen f{\"u}r lineare und ringf{\"o}rmige Oszillatoren, wurde ein Ringoszillator mit zwei Laserk{\"o}pfen aufgebaut, in welchen von außen mit einem Laser fester Frequenz eingestrahlt wird. Dieser emittiert bei einer Wiederholrate von 400 Hz eine Pulsenergie von Eout = 21 mJ bei nahezu beugungsbegrenzter Strahlqualit{\"a}t (M2 < 1,2). Die Verst{\"a}rkung dieser Laserpulse erfolgte zun{\"a}chst durch eine Vorverst{\"a}rkerstufe und anschließend durch zwei doppelbrechungskompensierte Hauptverst{\"a}rker im Doppeldurchgang. Eine gute Strahlqualit{\"a}t (M2 = 1,75) konnte unter anderem erzielt werden, indem der Doppeldurchgang durch die Hauptverst{\"a}rker mit einem phasenkonjugierenden Spiegel (SF6), auf der Basis der stimulierten Brillouin Streuung, realisiert wurde. Der entwickelte Laser emittiert Pulse mit einer L{\"a}nge von 25 ns und einer Energie von 250 mJ. Insgesamt wurde ein bisher einmaliges Lasersystem entwickelt. In der Literatur sind die erreichte Frequenzstabilit{\"a}t, Strahlqualit{\"a}t und Leistung in dieser Kombination bisher nicht dokumentiert. In der Zukunft soll durch den Einsatz von kerndotierten, keramischen Lasermaterialien, h{\"o}heren Pumpleistungen der Hauptverst{\"a}rker und phasenkonjugierenden Spiegeln aus Quarz die Pulsenergie des Systems weiter erh{\"o}ht werden.

  abstract  = {Ziel dieser Arbeit ist die ph{\"a}nomenologische Untersuchung der Feuchteempfindlichkeit der elektrischen Eigenschaften d{\"u}nner Polymerschichten. Diese Untersuchungen stellen gleichzeitig Vorarbeiten zur Entwicklung von Prototypen von zwei polymeren D{\"u}nnschicht-Feuchtesensoren dar, die sich durch die spezielle Auswahl der feuchtesensitiven Materialien jeweils durch eine besondere Eigenschaft gegen{\"u}ber kommerziellen Massenprodukten auszeichnen. Ziel der Entwicklungsarbeiten f{\"u}r den ersten Prototypen war die Konstruktion eines schnellen Feuchtesensors, der pl{\"o}tzliche und sprunghafte Feuchte{\"a}nderungen in der umgebenden Atmosph{\"a}re m{\"o}glichst rasch detektieren kann. Daf{\"u}r wurden d{\"u}nne Schichten von Poly-DADMAC auf Interdigitalstrukturen aufgebracht, die einen m{\"o}glichst direkten Kontakt zwischen feuchtesensitiver Schicht und umgebender, feuchter Atmosph{\"a}re gew{\"a}hrleisten. Als Messgr{\"o}ßen dienten die Wechselstromgr{\"o}ßen Widerstand und Kapazit{\"a}t der Schichten. Die Feuchtekennlinien der Schichten zeigen gute Konstanz und hohe Reproduzierbarkeit. Der Widerstand der Schichten {\"a}ndert sich durch den Einfluss von Feuchte je nach Schichtdicke um 3 bis 5 Gr{\"o}ßenordnungen und eignet sich als Messgr{\"o}ße f{\"u}r die Feuchtigkeit im gesamten Feuchtebereich. Die Hysterese der Filme konnte auf kleiner als 2,5\% r.F. bestimmt werden, die Reproduzierbarkeit auf besser als 1\% r.F. Die Ansprechzeit der Schichten l{\"a}sst sich schichtdickenabh{\"a}ngig zu 1 bis 10 Sekunden bestimmen. Hierbei zeigen besonders die d{\"u}nnen Schichten kurze Ansprechzeiten. Zielstellung f{\"u}r den zweiten Feuchtesensor war die Entwicklung eines Prototypen, dessen sensitive Schicht sich biostatisch und biozid verh{\"a}lt, so dass er in biotischen Umgebungen eingesetzt werden kann. Es wurden f{\"u}nf Polysulfobetaine synthetisiert, deren Biozidit{\"a}t und Biostatik mit dem Kontakttest nach R{\"o}nnpagel, dem ISO846-Test und Abbautests bestimmt wurde. Zwei Polymere - Poly-DMMAAPS (BT2) und Poly-[MSA-Styren-Sulfobetain] (BT5) - erwiesen sich als ausreichend biozid und biostatisch. Schichten dieser Polymere wurden auf Interdigitalstrukturen aufgezogen, anschließend wurden die Kennlinien dieser Proben aufgenommen. Die Messwerte zeigen f{\"u}r beide Polymere gute Konstanz und eine hohe Reproduzierbarkeit. BT2-Proben sind zwischen 20\% und 80\% r.F. besonders empfindlich und zeigen {\"u}ber einen Monat keine Langzeitdrift. Vernetzte Proben zeigen bis 50°C keinen temperaturbedingten Abfall der Feuchteempfindlichkeit. Der Einsatz vernetzter BT5-Schichten als kapazitiver Feuchtesensor ist bis etwa 70°C m{\"o}glich, die Schichten sind selbst nach Lagerung im Hochvakuum und mehrfacher Betauung stabil. Damit liegen zwei funktionsf{\"a}hige Prototypen von Feuchtesensoren vor, f{\"u}r die die meisten Kennwerte denen von vergleichbaren kommerziellen Feuchtesensoren entsprechen. Gleichzeitig zeichnen sie sich aber durch eine sehr niedrige Ansprechzeit bzw. eine ausreichende Lebensdauer unter biotischen Bedingungen aus.},

  abstract  = {Aim The aim of the present study was to examine young female volleyballers' body build, physical abilities, technical skills and psychophysiological properties in relation to their performance at competitions. The sample consisted of 46 female volleyballers aged 13-16 years. 49 basic anthropometric measurements were measured and 65 proportions and body composition characteristics were calculated. 9 physical ability tests, 9 volleyball technical skills tests and 21 psychophysiological tests were carried out. The game performance was recorded by the computer program Game. The program enabled to fix the performance of technical elements in case of each player. The computer program Game calculated the index of proficiency in case of each girl for each element. The first control group consisted of 74 female volleyballers aged 13-15 years with whom reduced anthropometry was provided and 28 games were recorded. The second control group consisted of 586 ordinary schoolgirls aged 13-16 years with whom full anthropometry was provided. Results In order to systematize all anthropometric characteristics, we first studied the essence of the anthropometric structure of the body as a whole. It turned out to be a characteristic system where all variables are in significant correlation between one another and where the leading characteristics are height and weight. Therefore we based the classification on the mean height and weight of the whole sample. We formed a 5 class SD classification. There are three classes of concordance between height and weight: small height - small weight, medium height - medium height, big height - big weight. The other two classes were classes of disconcordance between height and weight- pycnomorphs and leptomorphs. We managed to show that gradual increase in height and weight brought about statistically significant increase in length, breadth and depth measurements, circumferences, bone thicknesses and skinfolds. There were also systematic changes in indeces and body composition characteristics. Pycnomorphs and leptomorphs also showed differences specific to their body types in body measurements and body composition. The results of all tests were submitted to basic statistical analysis and all correlations were found between all the tests (volleyball technical skills, psychophysiological abilities, physical abilities), and all basic anthropometric variables (n = 49) and all proportions and body composition characteristics (n = 65). All anthropometric measurements and test results were correlated with the index of proficiency for all elements of the game. The best linear regression models were calculated for predicting proficiency in different elements of the game. We can see that body build and all kind of tests took part in predicting the proficiency of the game. The most essential for performing attack, block and feint were anthropometric and psychophysiological models. The studied complex of body build characteristics and tests results determine the players' proficiency at competitions, are an important tool for testing the player's individual development, enable to choose volleyballers from among schoolgirls and represent the whole body constitutional model of a young female volleyballer. Outlook Our outlook for the future is to continue recording of all Estonian championship games with the computer program Game, to continue the players' anthropometric measuring and psychophysiological testing at competitions and to compile a national register for assessment of development of individual players and teams.},

  abstract  = {Extract: [...] One of the often noted characteristic features of the Celtic languages is the absence of a singular verbal form with the meaning 'to have'.1 The principal way of expressing possession is through periphrastic constructions with prepositions (such as Irish ag, Scottish Gaelic aig 'at'; Welsh gan, Breton gant 'at, with') and appropriate forms of the substantive verb. Pronominal prepositions, another distinctive feature of the Celtic languages, consist of a preposition and a suffixed pronoun, or rather a pronominal personal ending. This construction may be analyzed as an instance of category fusion. Thus, the Irish and Welsh equivalents of English 'I have money' are T{\´a} airgead agam or Mae arian gen i, respectively, both literally meaning 'is money at-me/with-me'. This note discusses pronominal possessive constructions in Celtic languages (and some comparable examples from Celtic Englishes) and provides some background information on pronominal prepositions and comments on historical developments of these forms. It also discusses some terminological issues involved in labelling the construction in question. [...]},
