description: Combining galaxy cluster data from the ROSAT All-Sky Survey and the Chandra X-ray Observatory, cosmic microwave background data from the Wilkinson Microwave Anisotropy Probe, and galaxy clustering data from the WiggleZ Dark Energy Survey, the 6-degree Field Galaxy Survey and the Sloan Digital Sky Survey III, we test for consistency the cosmic growth of structure predicted by General Relativity (GR) and the cosmic expansion history predicted by the cosmological constant plus cold dark matter paradigm (LCDM). The combination of these three independent, well studied measurements of the evolution of the mean energy density and its fluctuations is able to break strong degeneracies between model parameters. We model the key properties of cosmic growth with the normalization of the matter power spectrum, sigma_8, and the cosmic growth index, gamma, and those of cosmic expansion with the mean matter density, Omega_m, the Hubble constant, H_0, and a kinematical parameter equivalent to that for the dark energy equation of state, w. For a spatially flat geometry, w=-1, and allowing for systematic uncertainties, we obtain sigma_8=0.785+-0.019 and gamma=0.570+0.064-0.063 (at the 68.3 per cent confidence level). Allowing both w and gamma to vary we find w=-0.950+0.069-0.070 and gamma=0.533+-0.080. To further tighten the constraints on the expansion parameters, we also include supernova, Cepheid variable and baryon acoustic oscillation data. For w=-1, we have gamma=0.616+-0.061. For our most general model with a free w, we measure Omega_m=0.278+0.012-0.011, H_0=70.0+-1.3 km s^-1 Mpc^-1 and w=-0.987+0.054-0.053 for the expansion parameters, and sigma_8=0.789+-0.019 and gamma=0.604+-0.078 for the growth parameters. These results are in excellent agreement with GR+LCDM (gamma~0.55; w=-1) and represent the tightest and most robust simultaneous constraint on cosmic growth and expansion to date.

description: Abstract
This contribution opens with a brief reflection on theoretical archaeology and practical material classification activities. Following this, the various questions that can be asked of the finds to be classified and how they condition the construction of typologies will be briefly addressed. Questions on chronology and technology; questions on the techno-anthropological context of use that force us to raise our gaze from the individual artefact to the surrounding universe; questions on the social use of artefacts (for distinctions of rank, gender, age, etc., but also for interactions aimed at establishing, or overcoming, limits and boundaries); questions on artefacts as means of exchange (of goods, but also of information or values); questions on what people thought of the artefacts they had (importance, but also indifference or rejection). An example, from an archaeological excavation, will show that everything also holds in the attempt to move from our etic classifications to emic classifications closer to the thinking of our past information.
In conclusion, a brief reflection is proposed on the importance of distinguishing not only recurring types but variants and special cases; on the usefulness of moving from reflections on the agency of single objects to reflections extended to collective habitus; on the definition of material culture as a complex object of investigation for which adequate classificatory reasoning is required.

description: In the Lorentz invariant formalism of compact space-time dimensions the assumption of periodic boundary conditions represents a consistent semi-classical quantization condition for relativistic fields. In [arXiv:0903.3680] we have shown, for instance, that the ordinary Feynman path integral is obtained from the interference between the classical paths with different winding numbers associated with the cyclic dynamics of the field solutions. By means of the boundary conditions, the kinematics information of interactions can be encoded on the relativistic geometrodynamics of the boundary [arXiv:1110.0315]. Furthermore, such a purely four-dimensional theory is manifestly dual to an extra-dimensional field theory. The resulting correspondence between extra-dimensional geometrodynamics and ordinary quantum behavior can be interpreted in terms of AdS/CFT correspondence. By applying this approach to a simple Quark-Gluon-Plasma freeze-out model we obtain fundamental analogies with basic aspects of AdS/QCD phenomenology.

EFECTO DE LA MINERA SOBRE LAS CONDICIONES FISICOQUÍMICAS Y LA PRODUCTIVIDAD DE ECOSISTEMAS HÍDRICOS

description: El estudio permitió determinar que la actividad minera genera cambios en la matriz fisicoquímica y la productividad de los ecosistemas hídricos que son intervenidos. La exploración de perfiles espacio temporales de distintos escenarios disturbados mostró que a pesar de que las variables fisicoquímicas del agua se van restableciendo a medida que el tiempo de cese de la actividad aumenta, los niveles de productividad aún después de 30 años pueden tener comportamientos distintos a su estado inicial, lo que sugiere que luego de la actividad minera es posible que las fuentes afectadas se configuren como nuevos ecosistemas hídricos con dinámicas físicas y biológicas distintas que requerirán de períodos de tiempo más largos para acercarse a su estado inicial.

A partir de los resultados obtenidos se recomienda que durante el proceso minero se evite la modificación de la estructura de los ecosistemas hídricos, eliminando las prácticas de desviación de cauce y controlando el vertimiento de residuos, partículas y sedimentos que cambian las condiciones fisicoquímicas del agua, para lo cual es necesario ordenar las actividades de captación y desagüe en las áreas a explotar y emplear sistemas de tratamiento primario y recirculación de los vertimientos para mejorar la calidad de las aguas vertidas al ecosistema. Para el caso de áreas intervenidas con diferentes temporalidades, se recomienda corregir el rumbo de los cauces cuando hayan sido modificados, evitando que las desviaciones y los cambios de pendientes ocasionen inundaciones o represamientos que puedan favorecer la reducción en el flujo del agua, el aumento en la concentración de nutrientes y la proliferación de algas que puedan llevar al sistema a estados eutróficos. Asimismo, es importante contribuir con la recuperación de las riberas para mejorar la estabilidad de la fuente hídrica, reducir el aporte de sedimentos por escorrentía y favorecer el intercambio con la biodiversidad, de tal manera que se acelere la dinámica biológica del ecosistema y con ello su proceso de resiliencia.

description: Der aktuelle Wissensstand über das menschliche gastrointestinale Mikrobiom basiert hauptsächlich auf die Analyse von Stuhlproben. Die intraindividuelle Zusammensetzung der Bakteriengemeinschaften in verschiedenen Regionen des GI-Trakts wurde bisher noch nicht untersucht. Unsere Studie war die erste, die untersucht hat, wie sich verschiedene mikrobielle Gemeinschaften entlang des gesamten Magen-Darm-Trakts derselben Individuen entwickeln. Primäres Ziel der Arbeit war es, die transkriptionell aktiven Bakterien an 8 verschiedenen Stellen des GI-Trakts (Speichel aus der Mundhöhle, Corpus und Antrum aus Magen, Duodenum, terminalem Ileum, Colon ascendens, Colon descendens und Faeces) von gesunden Probanden zu charakterisieren. Es wurde eine systematische Methodik zur Analyse der mikrobiellen Zusammensetzung auf allen phylogenetischen Ebenen verwendet, basierend auf Hochdurchsatz- Sequenzierungsmethoden und 16S-rRNA-Profilen. Die Ergebnisse liefern wichtige Informationen über die Zusammensetzung des gastrointestinalen Mikrobioms in Abhängigkeit davon, ob eine H. pylori-Infektion vorhanden ist oder nicht. Schlüsselentdeckungen aus unserer Analyse sind, a) dass der der GI-Trakt in vier verschiedene Regionen unterteilt werden kann bezugnehmend auf die Struktur der mikrobiellen Gemeinschaften (Mundhöhle, oberer GI-Trakt, unterer GI-Trakt, Faeces), b) dass bestimmte aktive Bakterien auf gewisse Regionen beschränkt sind und nur in bestimmten Nischen zu finden sind, c) dass das fäkale Mikrobiom die globale mikrobielle Struktur im gesamten GI-Trakt nicht komplett widerspiegelt. Diese neuen Erkenntnisse über die Zusammensetzung der Darmmikrobiota an verschiedenen anatomischen Stellen bei gesunden Menschen stellen eine solide Grundlage für weitere Untersuchungen zur funktionellen Rolle der Mikroben für die Gesundheit und die Erkrankungen dar.
Rural Legends : white hetero-settler masculinity, neoliberal ideology, and hegemony in The Heartland

description: This dissertation applies an interlocking spatial framework and critical discourse analysis to hegemonic masculinity, neoliberal ideology, and conceptions of the rural in Southeast Kansas. Drawing from decolonial, feminist, poststructural, and anarchist perspectives, it examines the different ways in which masculinities are discursively and materially embodied in rural spaces. The analysis utilizes empirical evidence, qualitative research methods, and fieldwork conducted in rural Kansas to highlight how mutually constitutive social axes of identification are intimately tied to place, as well as how socio-spatial relationships and neo(liberal) configurations of practice position differing entities as subjects. The research project also sheds light on taken-for-granted notions of masculinity and how hegemonic formations of race, class, gender, sexuality, ability, ethnicity, citizenship, religion, and nationality produce dynamic, spatialized oppressions and privileges. In addition, it seeks to elicit understandings of what is produced by (neo)liberal ideologies and masculinist subjectivities that rely upon the rhetoric of competition, self-reliance, and rugged individualism. Lastly, it illustrates the exclusionary, marginalizing, enabling, and normalizing tendencies that have developed in Southeast Kansas as a result of settler colonialism, conservative Christianity, the ideals of capitalism, gendered hierarchies, white supremacist processes of racialization, ableist social relations, heteronormativity, American nationalism, and liberal conceptions of the self.

description: Background & aim: Serum pepsinogen (PG) I and PG II are non-invasive parameters in the detection of atrophic gastritis. The diagnostic add on value of serum gastrin-17 (G-17) remains uncertain. The aim of the study was to assess the stability at different time point and to evaluate the influence of clinical factors on of these serum parameters. Methods: For stability analyses the plasma and serum samples from 23 subjects were processed at different time points. Ten additional patients were included to evaluate the influence of upper GI endoscopy and 18 patients to evaluate the effect of bowel cleansing before colonoscopy. Results: PG I, PG II and G-17 levels were not statistically different in serum and plasma. PG I and PG II serum levels were stable overtime and their assessment is not influenced by laboratory factors. G-17 is associated with time-dependent degradation (p= 0.0001). Upper GI endoscopy and bowel preparation prior colonoscopy were associated with minimal variations in PG I, PG II, while G-17 showed subject-specific alterations. Conclusions: PG I and PG II serum levels are stable overtime. However, G- 17 stability is closely dependent on time of processing and storage. Upper GI endoscopy and colonoscopy preparation lead to minimal non-significant changes in basal PG I, PG II and G-17 levels.

description: Motivated by applications to probability and mathematical finance, we consider a parabolic partial differential equation on a half-space whose coefficients are suitably Holder continuous and allowed to grow linearly in the spatial variable and which become degenerate along the boundary of the half-space. We establish existence and uniqueness of solutions in weighted Holder spaces which incorporate both the degeneracy at the boundary and the unboundedness of the coefficients. In our companion article [arXiv:1211.4636], we apply the main result of this article to show that the martingale problem associated with a degenerate-elliptic partial differential operator is well-posed in the sense of Stroock and Varadhan.

description: Kv1.3-Kaliumkanäle spielen eine zentrale Rolle bei der Aktivierung, Proliferation und Apoptose von T-Lymphozyten und sind vielversprechende therapeutische Zielstrukturen. Bisher sind jedoch keine Pharmaka zur Kv1.3-Kanal-Blockade klinisch lizensiert. Memantin, ein gut verträglicher, bei der Behandlung der Alzheimer Demenz eingesetzter NMDARezeptor (NMDAR)-Antagonist, hemmt in Lymphozyten Kv1.3-Kanäle. In dieser Arbeit wird aufgezeigt, dass die NMDAR-Antagonisten Memantin, Ifenprodil und MK-801 die Proliferation und Migration muriner und humaner T-Lymphozyten in vitro reduzieren. In Memantin-behandelten Alzheimer-Patienten wurde eine veränderte Zusammensetzung der T-Zellpopulationen im peripheren Blut sowie eine reduzierte T-Zellreaktivität ex vivo nachgewiesen. Memantin-induzierte inhibitorische Effekte auf T-Zellfunktionen, und somit auf die adaptive Immunantwort, könnten einerseits vorteilhaft die Neuroinflammation der Alzheimer Demenz beeinflussen, andererseits die unter Memantin-Behandlung auftretende erhöhte Infektionsrate mitbedingen. Im zweiten Schwerpunkt der Dissertation wird dargestellt, dass Memantin die Cytarabin-induzierte Proliferationshemmung und den Zelltod von ALL- und AML-Zelllinien sowie primären leukämischen Blasten von Patienten mit akuter Leukämie potenziert. Dabei wurden eine verstärkte Hemmung der ERK1/2- und AKTSignalwege und eine Steigerung der mitochondrialen Apoptose nachgewiesen. Memantin könnte daher als Kv1.3-Kanal-Inhibitor bei der Cytarabin-basierten Chemotherapie akuter Leukämien von klinischem Interesse sein. Kombinationsstrategien mit Memantin und Cytarabin wären fortführend in geeigneten Leukämiemodellen zu überprüfen.

description: The current state of the economy with the deterioration of economic results, transformational transfor-mations is characterized by the lack of a system of management of the dynamics of growth of economic indica-tors due to the transition to innovative sources of economic development, which activates the issue of provid-ing such changes in controlled character. The economic development of the region concerns not only financial revenues to local budgets, but also an increase in the overall welfare of the population, through prism of prior-ity directions of development. The path to improving the life and economic development of the Vinnytsia region is possible taking into account transformational processes, but achieving this involves solving the complex of goals and tasks facing management bodies. The current state, trends and problems of reproduction of the economic potential of sustainable develop-ment of Ukraine and its regions are investigated. An analysis of the ineffectiveness of enterprises of certain types of activities of the region's economy is carried out. The formation of the system of indicators of the devel-opment of regional socio-economic systems is proposed and a systematic and integrated assessment of the eco-nomic potential of the development of the Vinnytsia region is carried out. Considerable attention is bought to assess the economic potential of the region, prospects for modernization of social infrastructure and the for-mation of sustainable economic growth in the region. The basic and strategic directions of rationalization of resource use spheres are formulated on the basis of assessment of minerals, improving the management of the agricultural complex of the region as the main determinants of the effective use of territorial development of regional complexes. The SWOT-analysis of the Vinnytsia region has been conducted, the strengths and weak-nesses of development and economic output of the region on cross-border markets and the world arena are characterized. The possibilities of the region are outlined, which will contribute to further competitiveness of the region at the level of other economic regions of Ukraine. Provided threats of development that arise under the influence of external forces that interfere with rapid and sustainable growth. The main problems and prior-ity directions of development of the economy of Vinnytsia region are determined.

description: Rapid growth in the demand for millimetre-wave components in telecommunications and defence-related applications has resulted in an increasing need for monolithic microwave integrated circuits (MMICs). In partnership with the Australian Department of Defence and commercial clients, CSIRO Telecommunications and Industrial Physics is putting a substantial research effort into developing MMIC-based telecommunication systems. MMlCs, fabricated using pseudomorphic HEMTs and Schottky diodes as active devices, cover a frequency range of 1-100 GHz. Diode-based mixers, multipliers, up and down converters, HEMT-based amplifiers (both for low-noise and power applications) and composite diode and HEMT-based circuits such as voltage control oscillators have been designed and successfully fabricated. These circuits have been used in applications such as wireless backhaul links and high-data-rate wireless communication and local-area networks. This paper presents an overview of CSIRO s MMIC development program.

description: Die vorliegende Arbeit beschäftigt sich mit der kutanen Bioverfügbarkeit der Aminosäure L-Citrullin nach epikutaner Applikation ex vivo. Im Vordergrund steht dabei die Untersuchung der Penetrations- und Permeationsdynamik. Die Versuche erfolgen an gesunden Hautexzisatennach Mammareduktionsplastik in einer Diffusionszelle nach Franz. Durch extern appliziertes L-Citrullin soll die NO-Synthase-Aktivität (NOS-Aktivität) über negative-Feedback-Hemmung gebremst und somit die NO-Entstehung inhibiert werden, um entzündliche Prozesse zu modulieren. L-Citrullin selbst kann dabei auch aufgrund seines antioxidativen Potenzials in vitalen Zellen die Folgen von oxidativem Stress neutralisieren. Weiterhin steht die Verbesserung des natürlichen Feuchthaltefaktors (NMF) im Vordergrund, um die Hydratation des Stratumcorneum zu erhöhen und den transepidermalen Wasserverlust (TEWL) einzuschränken. Daraus resultiert das dermatopharmazeutische Interesse an der nicht-essentiellen, nicht-proteinogenen Aminosäure L-Citrullin, die eine wichtige Position im Krebs-Heinseleit-Zyklus einnimmt.
description: The present study examines the cutaneous bioavailability of the aminoacid L-citrulline after epicutaneous application ex vivo. Thereby, the focus of this work lies on the dermal penetration and permeation dynamic. The experiments are made on excised human skin from reduction mammoplasty in a Franz diffusion cell. The external application of L-citrullineinduces a negative feedback mechanism of the NO-synthase-activity (NOS-activity) and decreases the nitricoxide availability to modulate inflammatory processes. L-citrulline itself can neutralize the effects of oxidative stress because of its antioxidative potential in vital cells. Furthermore, it can enhance the natural moisturizing factor (NMF) to increase the hydration of the stratumcorneum and to decrease the transepidermal waterloss (TEWL). This explains the dermatopharmaceutical interest in the nonessential, nonproteinogenic aminoacid L-citrulline, which has an important position in the urea cycle.

description: We report the development of an InP-based monolithic microwave integrated circuit production line to provide InP HEMT and InP HBT MMICs for both government and commercial applications. This three-inch fabrication facility was originally developed to produce high-performance InP HEMT and InP HBT MMICs specifically designed for government applications. Recent examples of performance capability include InP HEMT low-noise MMIC amplifiers with 12 dB gain at 155 Ghz, and the first fundamental frequency 94 Ghz HBT oscillator. However, InP-hased heterojunction devices also provide specific advantages for some high-volume commercial applications. We present here the production and performance results of InP HEMT and HBT MMICs for governmnent and commercial applications.

description: We consider a discrete time particle model for kinetic transport on the two dimensional integer lattice. The particle can move due to advection in the $x$-direction and due to dispersion. This happens when the particle is free, but it can also be adsorbed and then does not move. When the dispersion of the particle is modeled by simple random walk, strange phenomena occur. In the second half of the paper, we resolve these problems and give expressions for the shape of the plume consisting of many particles.

description: The Lambda-CDM model is the best fit to cosmological data, and to the observed galactic rotation curves. However, in the absence of a direct detection of dark matter one should explore theories such as MOND, and perhaps also modified gravity theories like fourth order gravity and Scalar-Tensor-Vector Gravity [STVG] as possible explanations for the non-Keplerian behaviour of galaxy rotation curves. STVG has a modified law for gravitational acceleration which attempts to fit data by fixing two free parameters. We show that, remarkably, the biharmonic equation which we get in the weak field limit of the field equations in a fourth order gravity theory implies a modification of Newtonian acceleration which is precisely of the same repulsive Yukawa form as in the STVG theory, and the corrections could in principle be large enough to try and explain the observed rotation curves. We also explain how our model provides a first principles understanding of MOND. We also show that STVG and fourth order gravity predict an acceleration parameter $a_0$ whose value is of the same order as in MOND.

description: The aim of the experiment was to investigate the effect of dry echinacea extract on the productivity and feed consumption of Pharaoh meat quails. The dry extract of the underground part of Echinacea pallida in the form of a homogeneous brown pow-der is the researched feed additive. The additive contains biologically active substances, i.e., polysaccharides (fructosans) and phenolic compounds (hydroxycinnamic acids), which have immune, antimicrobial and anti-inflammatory effects. The research of the effectiveness of the Echinacea pallida extract feed additives application in the quails feeding were conducted at a research farm of Vinnytsia National Agrarian University. Scientific experiments were carried out on poultry according to generally accepted methods. Four groups of experimental birds were formed, each group had 50 heads selected by the method of analogous groups. The experiment lasted for 56 days. Additional feeding by different doses of Echinacea pallida extracts as a part of complete feed had a posi-tive effect on the live weight of the experimental quails. Thus, the additional feeding by the average dose of the researched additive in the amount of 12 mg per kg of live weight increases live weight, average daily and abso-lute growth of females by 13.3% (P <0.001), 14.3% and 13.5% (P <0.001) and males by 19.7% (P <0.001), 23.1% and 20.3% in comparison with control analogues. Quails consuming a phytobiotic supplement of Echinacea pallida dry extract has reduced feed consump-tion per 1 kg of growth by 14.9%, relative to control. It has been found that the use of Echinacea pallida extract in the feeding of quails increases the safety of livestock by 4%.

description: We investigate a problem posed by L. Hauswirth, F. Hélein, and F. Pacard, namely, to characterize all the domains in the plane that admit a "roof function", i.e., a positive harmonic function which solves simultaneously a Dirichlet problem with null boundary data, and a Neumann problem with constant boundary data. Under some a priori assumptions, we show that the only three examples are the exterior of a disk, a halfplane, and a nontrivial example. We show that in four dimensions the nontrivial simply connected example does not have any axially symmetric analog containing its own axis of symmetry.

Understanding the creative process : personal signatures and cross-domain interpretations of ideas
Creators: name: Ranjan, Apara
Publisher: name: University of British Columbia

description: This dissertation investigated to what extent the expression of personal creative style is recognizable within and across domains. It also investigated to what extent two pieces of art in disparate domains (e.g., a piece of music and a painting) resemble each other, when the first is used as inspiration for the creation of the second. The first set of studies tested the hypothesis that creative style is recognizable within and across domains. Art students who were shown sets of paintings by (1) five famous artists, and (2) their peers identified the artists at above-chance levels. Similarly, creative writing students were given passages by famous writers and by their peers and they identified the writers at significantly above-chance levels. When asked to produce works of art, the creative writing students were able to identify at above chance levels which peer produced each piece of art. Finally, when art students were asked to produce non-painting artworks, they identified which peer produced each non-painting artwork. These findings support the hypothesis that creative styles are recognizable not just within but also across domains. The second study tested whether people were able to match creative outputs with the cross-domain stimuli that inspired them. Three expert painters created four paintings each. Each painting was the artist’s interpretation of one of four different pieces of instrumental music. The participants were able to identify which paintings were inspired by which musical pieces at modestly above-chance levels. They rated similarities between every painting pair, every musical piece pair, and every painting-music pair. Also, all the paintings and musical pieces were rated using a set of psychological variables (e.g., arousal, complexity). When the artists’ creative styles were clearly recognizable in their paintings, it was more difficult for participants to identify the musical pieces that inspired those paintings. This dissertation demonstrates that both personal style and the core of a creative idea are to some extent independent of the domains in which they are initially expressed. This dissertation suggests that individuals have multiple avenues for the expression of personal style, and core ideas have multiple avenues for their creative manifestation.

description: This paper explores the following regularity properties and their relationships for simple, not-necessarily-unital C*-algebras: (i) Jiang-Su stability, (ii) Unperforation in the Cuntz semigroup, and (iii) slow dimension growth (applying only in the case that the C*-algebra is approximately subhomogeneous). An example is given of a simple, separable, nuclear, stably projectionless C*-algebra whose Cuntz semigroup is not almost unperforated. This example is in fact approximately subhomogeneous. It is also shown that, in contrast to this example, when an approximately subhomogeneous simple C*-algebra has slow dimension growth, its Cuntz semigroup is necessarily almost unperforated.

description: Ein möglicher Einfluss von Sexualhormonen & Insulin wird auf die Entstehung von Arthrose vermutet. Die Östrogenrezeptoren ERα & ERβ sowie der Insulinrezeptor IR sollen an humanen Gelenkknorpelzellen auf mRNA- & Proteinebene detektiert werden. Durch verschiedene hormonelle Stimulationen soll ein Zusammenhang der Wirkung zwischen 17β-Östradiol & Insulin aufgezeigt werden. Die immortalisierten Knorpelzelllinien C-28/I2 & T/C-28a2 sowie primäre humane Gelenkknorpelzellen werden in Zellkulturen mit beiden Hormonen stimuliert. Die Hormonrezeptoren werden mit PCR, Western Blot & Immunzytochemie bestimmt. Zusätzlich wird der radioaktiv markierte Prolineinbau in einer Zellkultur untersucht & die Kollagensynthese mittels ELISA bestimmt. Der Nachweis der Rezeptoren gelingt auf mRNA- & Proteinebene. Eine unterschiedlich starke Exprimierung kann in Abhängigkeit von Geschlecht & variierenden Hormonstimulationen teilweise gezeigt werden. Der Prolineinbau & der Kollagengehalt in der Zellkultur geben Anhaltspunkte für eine Interaktion von 17β-Östradiol und Insulin. Diese in vitro nachgewiesenen Zusammenhänge können ein erster Hinweis für tatsächliche Interaktionen in vivo darstellen.
description: A possible influence of sexual hormones & insulin is expected in the development of osteoarthritis. The estrogen receptors ERα & ERβ as well as the insulin receptor IR are supposed to be detected on mRNA & protein level. A connection between the effect of 17β-estradiol & insulin is supposed to be shown with different hormonal stimulations. The immortalized chondrocyte cell lines C-28/I2 & T/C-28a2 as well as primary human articular chondrocytes in cell cultures are stimulated with both hormones. The hormone receptors are detected with PCR, western blot & immunocytochemistry. Additionally the radioactive marked prolin incorporation is analyzed & the synthesis of collagen is detected with ELISA. The detection of the receptors is successful on mRNA & protein level. A different expression can be shown partially in dependence of sex & various hormonal stimulations. The prolin incorporation & the concentration of collagen in the cell culture assumes an interaction of 17β-estradiol & insulin. These detected connections in vitro can be a first indication for real interactions in vivo.
Macroscopic Observables Detecting Genuine Multipartite Entanglement and Partial Inseparability in Many-Body Systems

description: We show a general approach for detecting genuine multipartite entanglement (GME) and partial inseparability in many-body-systems by means of macroscopic observables (such as the energy) only. We show that the obtained criteria, the "GME gap" and "the k-entanglement gap", detect large areas of genuine multipartite entanglement and partial entanglement in typical many body states, which are not detected by other criteria. As genuine multipartite entanglement is a necessary property for several quantum information theoretic applications such as e.g. secret sharing or certain kinds of quantum computation, our methods can be used to select or design appropriate condensed matter systems.

description: Hermann Welcker (1822-1897) war Professor für Anatomie und erster Direktor des heutigen halleschen Anatomischen Institutes. Das Ziel der Dissertation ist es, Welckers kraniologische Forschung unter besonderer Berücksichtigung der halleschen Schädelsammlung nachzuvollziehen. Im ersten Arbeitsschritt erfolgte die Bestandsaufnahme der halleschen Schädelsammlung. Welckers kraniologische Forschungsschwerpunkte werden dargelegt. Im zweiten Arbeitsschritt wurden 707 Schädel makroskopisch unter morphologischen Gesichtspunkten untersucht. Hierbei lagen die Schwerpunkte auf der Diagnostik von akzessorischen Schädelknochen und -nähten. Häufigkeiten der einzelnen überzähligen Knochen konnten ermittelt werden. Akzessorische Suturen am Stirnbein wurden klassifiziert. Die Prävalenz von Stirn- und Supranasalnaht in der halleschen Schädelsammlung wurde untersucht. Im dritten Arbeitsschritt wurden elf Erwachsenenschädel hinsichtlich akzessorischer Suturen am Stirnbein computertomografisch untersucht.
description: Hermann Welcker (1822-1897) was professor of anatomy and first director of Halle’s current anatomical institute. This thesis aims for comprehension of Welcker’s craniological studies, particularly considering Halle’s collection of skulls. At first, an inventory of Halle’s collection of skulls was made. Welcker’s craniological main researches are posed. Considering morphological aspects, 707 skulls were macroscopically examined as a second task. In so doing, the diagnosis of accessory skull bones and sutures was focused on. The frequency of accessory bones could be determined. Additional sutures at the frontal bone were classified. The prevalence of metopic suture and supranasal suture was explored in Halle’s collection of skulls. Regarding accessory sutures at the frontal bone, eleven adult skulls were examined with the help of computed tomography in a third working step.

description: We show that a transitively reduced digraph has a confluent upward drawing if and only if its reachability relation has order dimension at most two. In this case, we construct a confluent upward drawing with $O(n^2)$ features, in an $O(n) \times O(n)$ grid in $O(n^2)$ time. For the digraphs representing series-parallel partial orders we show how to construct a drawing with $O(n)$ features in an $O(n) \times O(n)$ grid in $O(n)$ time from a series-parallel decomposition of the partial order. Our drawings are optimal in the number of confluent junctions they use.

The Teacher and the skinhead : a style of privilege and the privilege of style : a critical examination of subcultural style and its relation to youth and privilege
Creators: name: Marchand, Michael Joshua
Publisher: name: University of British Columbia
Year: 2014

description: In the contemporary educational context, youth and their relationships to the larger society of which they exist is a complex field of deep symbolic and cultural meaning. Success in the system is often based on complex negotiations of privilege that shape the outcomes and expectations we place upon youth. This thesis takes as its central theoretical underpinnings the notion, as expressed by Paulo Friere and his successors within Critical Pedagogy, that access to education and its benefits is heavily mediated by relations of power, privilege and social capital. The concept of subculture as it was developed by thinkers such as Stuart Hall and Dick Hebdige and its deployment as a means of regulating and shaping youth provides a frame for the analysis of the various ways in which narratives of privilege shape our image and perception of youth and the institutions of education. The thesis examines the how images and portrayals of youth are shaped by examining the representations of youth and subculture in film and in art in the nineteen eighties and nineteen nineties. The analysis, instead of focusing upon oppression, looks at the ways in which narratives of privilege create oppression through the strategic privileging of particular identities and ways of being for youth and how this impacts upon them through institutions of education.
