description: Educational portal (EP) is a multi-function website that allows access to activities such as public and private sections, data retrieval and submission, personalized content and so on for the educational system. This study investigated the specific requirement for the enhancement of quality and behavior of EP with regards to time and cost using Obafemi Awolowo University (OAU), Ile-Ife, Nigeria as a case study. A test automation framework was designed using unified modelling language and implemented in Java programming language. MySQL and Excel database were used to store test data. The framework developed was evaluated using Test Time Performance (TTP), Performance Test Efficiency (PTE) and Automation Scripting Productivity (ASP) metrics. The results from the evaluation of the sample data provided showed that ASP produced a tested outcome of 360 operations per hour, PTE yielded 80% and TTP was just 4%. Based on the recorded performance, it is evident that the research can provide quick and firsthand information to quality assurance analyst and software testers, thereby reducing maintenance cost during software development.

This measurement of v2(pT), as a function of transverse momentum, in 0–5% centrality p+Au at √sNN = 200 GeV collisions completes a set of measurements with engineered initial geometries at RHIC, including the p+Au, d+Au, and 3 He+Au.
The law of annual general meetings examined from a perspective of certain economic theories
Creators: name: Curwood, James Arthur
Publisher: name: University of British Columbia

description: The large irsodern corporation possesses characteristics which set it apart from other corporations both present and past. The existence of the annual general meeting of shareholders within the structure of these large entities suggests problems of a fundamental nature respecting the principles of law governing those meetings. The extent to which these problems, suggested by the characteristics of the modern corporation and their effects, compel a need for a reconsideration of the legal principles respecting annual general meetings, is the subject of this essay. It is the thesis of this essay that the attributes of the large modern corporation and their effects have in fact shattered the integrity of the law relating to annual general meetings. It is submitted that the legal principles governing these meetings no longer serve most of the functions of law and ought, therefore, be reconsidered. The method used to establish this thesis will be to observe the existence of the annual general meeting from the perspectives of law and economics, individually. From these two observations two models will be constructed which will then be compared to discover any discrepancies. As the economic perspective is assumed, in this essay, to be the correct one, the discrepancies that exist between the two models must indicate inaccuracies in the legal perspective. Only the descriptive function of law is considered in this essay; the prescriptive function is not here subject to criticism.
Stem cell pathways in the basal-like breast carcinoma: the role of beta-catenin and HIF-1alpha

description: Basal-like tumor is an aggressive breast carcinoma subtype that displays an expression signature similar to that of the basal/myoepithelial cells of the breast tissue. Basal-like carcinoma are characterized by over-expression of the Epidermal Growth Factor receptor (EGFR), high frequency of p53 mutations, cytoplasmic/nuclear localization of beta-catenin, overexpression of the Hypoxia inducible factor (HIF)-1alpha target Carbonic Anhydrase isoenzime 9 (CA9) and a gene expression pattern similar to that of normal and cancer stem cells, including the over-expression of the mammary stem cell markers CD44.
In this study we investigated the role of p53, EGFR, beta-catenin and HIF-1alpha in the regulation of stem cell features and genes associated with the basal-like gene expression profile. The findings reported in this investigation indicate that p53 inactivation in ductal breast carcinoma cells leads to increased EGFR mRNA and protein levels. In our experimental model, EGFR overexpression induces beta-catenin cytoplasmatic stabilization and transcriptional activity and, by that, leads to increased aggressive features including mammosphere (MS) forming and growth capacity, invasive potential and overexpression of the mammary stem cell gene CD44.
Moreover we found that EGFR/beta-catenin axis promotes hypoxia survival in breast carcinoma cells via increased CA9 expression. Indeed beta-catenin positively regulates CA9 expression upon hypoxia exposure.
Interestingly we found that beta-catenin inhibits HIF-1alpha transcriptional activity. Looking for the mechanism, we found that CA9 expression is promoted by HIF-1alpha and cytoplasmatic beta-catenin further increased it post-transcriptionally, via direct mRNA binding and stabilization. These data reveal a functional beta-catenin/HIF-1alpha interplay among hallmarks of basal-like tumors and unveil a new functional role for cytoplasmic beta-catenin in the phenotype of such tumors. Therefore it can be proposed that the interplay here described among EGFR/beta-catenin and HIF-1alpha may play a role in breast cancer stem cell survival and function.

description: We introduce the domain structure for stationary black hole space-times. Given a set of commuting Killing vector fields of the space-time the domain structure lives on the submanifold where at least one of the Killing vector fields have zero norm. Depending on which Killing vector field has zero norm the submanifold is naturally divided into domains. A domain corresponds either to a set of fixed points of a spatial symmetry or to a Killing horizon, depending on whether the characterizing Killing vector field is space-like or time-like near the domain. The domain structure provides invariants of the space-time, both topological and geometrical. It is defined for any space-time dimension and any number of commuting Killing vector fields. We examine the domain structure for asymptotically flat space-times and find a canonical form for the metric of such space-times. The domain structure generalizes the rod structure introduced for space-times with D-2 commuting Killing vector fields. We analyze in detail the domain structure for Minkowski space, the Schwarzschild-Tangherlini black hole and the Myers-Perry black hole in six and seven dimensions. Finally we consider the possible domain structures for asymptotically flat black holes in six and seven dimensions.

description: Given a code from a shift space to an irreducible sofic shift, any two of the following three conditions -- open, constant-to-one, (right or left) closing -- imply the third. If the range is not sofic, then the same result holds when bi-closingness replaces closingness. Properties of open mappings between shift spaces are investigated in detail. In particular, we show that a closing open (or constant-to-one) extension preserves the structure of a sofic shift.

description: Conceptual Graphs (CG) are a graph-based knowledge representation and reasoning formalism; fuzzy Conceptual Graphs (fCG) constitute an extension that enriches their expressiveness, exploiting the fuzzy set theory so as to relax their constraints at various levels. This paper proposes a comparative study of existing approaches over their respective advantages and possible limitations. The discussion revolves around three axes: (a) Critical view of each approach and comparison with previous propositions from the state of the art; (b) Presentation of the many possible interpretations of each definition to illustrate its potential and its limits; (c) Clarification of the part of CG impacted by the definition as well as the relaxed constraint.
A Comparison of Free and Mapped Meshes for Static Structural Analysis.pdf

Subjects: classificationCode: 401707
subject: Solid mechanics

description: This study addresses the challenge faced by Finite Element Analysts when choosing between free and mapped meshes, especially in terms of convergence stability and solution accuracy. The investigation focuses on 3D solid models under static structural loading, analyzed using Ansys® and MSC Patran®. Both free and mapped mesh types, employing equivalent 3D solid elements, are used to assess an aircraft structural component under design load conditions, with fixed boundaries. For free meshes, Tet10 elements in Patran (equivalent to Solid 72 in Ansys) are used, whereas for mapped meshes, CPENTA / CHEXA elements in Patran (equivalent to Wed6 / Hex8 in Ansys) are employed. Mesh convergence studies ensure that discretization does not affect the numerical solution. Notably, a significant stress increase is observed with successive refinement of free meshes, while mapped meshes achieve mesh independence at coarser refinement levels. Comparison of fringe plots indicates the same location for maximum deformation and equivalent stress in both free and mapped mesh models. The findings demonstrate that free meshes tend to underpredict maximum deformation and equivalent stress compared to mapped meshes, with both meshes showing deformation and stress at consistent locations. The findings underscore the importance of carefully choosing the appropriate mesh type, particularly when analyzing critical structural components, to ensure reliability and accuracy in FEA simulations.

Latest numbers for decay constants f_B and f_{B_s} are also presented. Combining our lattice results with experimental determinations of the mass differences ΔM_d and ΔM_s leads to an important ratio of elements of the CKM matrix, |V_{td}|/|V_{ts}| = 0.214(1)(5) and an updated Standard Model number for the branching fraction Br(B_s -> mu^+ mu^-) = 3.19(19) x 10^{-9}. Preliminary new results for f_{B_s} based on other actions are also described.

Mechanisms of liquid-phase sintering in Fe-Cu mixtures
Creators: name: Magee, Brian Eric
Publisher: name: University of British Columbia
Year: 2010

description: Continuous dilatometry and metallographic techniques have been used to study the..dimensional changes which occur when iron-copper compacts are sintered above the melting point of copper. Among the variables investigated were: a) the effect of solid-state presintering the compacts, b) copper content, c) particle size, d) initial compact density and e) the heating rate through the melting temperature. Five different processes causing dimensional change were identified. Three contraction processes operated consecutively: 1) rearrangement, 2) solution-precipitation and 3) coalescence. Two expansion processes operated simultaneously with processes (1) and (2), they were: 4) expansion due to diffusion of copper into iron and, 5) expansion resulting from the penetration of γ-iron grain boundaries by copper liquid. In the early stages of sintering the iron was in a 'dispersed' state, while in the last stage it existed as a solid network. That change is attributed to an increase in the values of the dihedral and wetting angles (⌽ and θ) of the liquid-solid system during sintering. It is suggested that initially high concentrations of oxygen at the solid-liquid interfaces causes a low value of γ [sub SL] and thus, the values of ⌽ and θ are initially low. As the oxygen concentration at those interfaces decreases with time, ⌽ and θ become positive, permitting coalescence to occur. Differences among the results of previous investigations in the Fe-Cu system have been explained by attributing them to differences in the thermal histories of compacts. It is suggested that some additions to the Fe-Cu system, which reduce expansion during liquid-phase sintering, do so by acting as internal de-oxidants and preventing a zero dihedral angle from being attained.

description: The present work has been done on the baryons containing one, two, or three bottom quarks. In this article, the ground-state masses of $Ω_{b}^{-}$, $Ξ_{bb}^{0}$, $Ξ_{bb}^{-}$, $Ω_{bb}^{-}$, and $Ω_{bbb}^{*-}$ baryons are calculated within the framework of Regge phenomenology. Further, the values of Regge slopes and Regge intercepts for singly, doubly, and triply bottom baryons are estimated in both the ($J,M^{2}$) and ($n,M^{2}$) planes to calculate the excited-state masses of these baryons. Here our attempt is to assign a possible spin-parity to recently observed some singly bottom baryons and our results could provide useful information for future experimental searches. Our calculated masses are in agreement with the experimental observations where available and close to other theoretical predictions.

Using a five-hole tapered 1D photonic crystal mirror and precise control of the cavity length, we designed cavities with theoretical Quality factors as high as 14 million. By detecting the cross-polarized resonantly scattered light from a normally incident laser beam, we measure a Quality factor of nearly 750,000. The effect of cavity size on mode frequency and Quality factor was simulated and then verified experimentally.

Angular Momentum Transfer and Lack of Fragmentation in Self-Gravitating Accretion Flows

description: Rapid inflows associated with early galaxy formation lead to the accumulation of self-gravitating gas in the centers of proto-galaxies. Such gas accumulations are prone to non-axisymmetric instabilities, as in the well-known Maclaurin sequence of rotating ellipsoids, which are accompanied by a catastrophic loss of angular momentum (J). Self-gravitating gas is also intuitively associated with star formation. However, recent simulations of the infall process display highly turbulent continuous flows. We propose that J-transfer, which enables the inflow, also suppresses fragmentation. Inefficient J loss by the gas leads to decay of turbulence, triggering global instabilities and renewed turbulence driving. Flow regulated in this way is stable against fragmentation, whilst staying close to the instability threshold for bar formation -- thick self-gravitating disks are prone to global instabilities before they become unstable locally. On smaller scales, the fraction of gravitationally unstable matter swept up by shocks in such a flow is a small and decreasing function of the Mach number. We conclude counterintuitively that gas able to cool down to a small fraction of its virial temperature will not fragment as it collapses. This provides a venue for supermassive black holes to form via direct infall, without the intermediary stage of forming a star cluster. Some black holes could have formed or grown in massive halos at low redshifts. Thus the fragmentation is intimately related to J redistribution within the system: it is less dependent on the molecular and metal cooling but is conditioned by the ability of the flow to develop virial, supersonic turbulence.

Das Primat funktionaler Differenzierung und die Kontingenz sozialer Ungleichheit
Creators: name: Torres Junior, Roberto Dutra
Publisher: name: Zeitschrift für Theoretische Soziologie
Year: 2014

description: Der Versuch, die Verbindung von Ungleichheitsanalyse und Gesellschaftstheorie wiederherzustellen, ist heutzutage zu einem der wichtigsten Schwerpunkte soziologischer Theoriebildung geworden und besonders stark von der Diskussion über den Zusammenhang von sozialer Ungleichheit und funktionaler Differenzierung geprägt. Die Debatte dreht sich vor allem um den Stellenwert der beiden Begriffe innerhalb einer umfassenden Gesellschaftstheorie. Die Primatthese Luhmanns, nach der die funktionale Differenzierung die stratifizierte Differenzierung als primäre Differenzierungsform ersetzt hat, wird dabei häufig als Auflösung des Begriffes strukturierter sozialer Ungleichheit wahrgenommen. Der Beitrag vertritt zwei Thesen: Die erste These lautet, dass das Primat funktionaler Differenzierung als ein gesellschaftliches Selbstverständlichwerden dieser Differenzierungsform verstanden werden sollte, was keineswegs eine Bedeutungslosigkeit sozialer Ungleichheit für die soziale Ordnung impliziert. Die zweite These geht davon aus, dass das Primat funktionaler Differenzierung mit der Kontingenzsetzung sozialer Ungleichheit in ihrem Beitrag zur Herstellung sozialer Ordnung einhergeht.

In this short paper we analyze the GUP effects on neutron interferometry, showing that the obtained phase shifts depend on the mass and velocity of the particle. New upper bounds on the dimensionless GUP parameter have been found that are in agreement with the literature.

description: We study charge transport in an ionic solution in a confined nanoscale geometry in the presence of an externally applied electric field and immobile background charges. For a range of parameters, the ion current shows non-monotonic behavior as a function of the external ion concentration. For small applied electric field, the ion transport can be understood from simple analytic arguments, which are supported by Monte Carlo simulation. The results qualitatively explain measurements of ion current seen in a recent experiment on ion transport through a DNA-threaded nanopore (D. J. Bonthuis et. al., Phys. Rev. Lett, vol. 97, 128104 (2006)).

description: Der Begriff des sozialen Milieus hat vor allem in seiner Reformulierung durch die Forschungen von Vester et al. (2001) (aber auch: Schulze 1992) einen Wandel erfahren: Er bezeichnet eine Form der Vergemeinschaftung, deren Kohäsion durch lokale und regionale Ausprägungen eines Lebensstils bzw. einer Mentalität und eine relativ starke Interaktionsnähe stabilisiert wird. Vester et al. stützen theoretisch die Analyse sozialer Milieus vor allem auf eine bestimmte Lesart des Habitusbegriffs, die es zu erlauben scheint, Milieus als Gruppen mit ähnlichem Habitus“ (Vester 2001: 24) zu konzipieren. Der Habitus als Gesamtheit „umfassende(r) Klassifikations- Bewertungs- und Handlungsschemata“ (Vester 2001: 169), die eine gemeinsame Haltung, einen gemeinsamen Lebensstil, eine gemeinsame Mentalität erzeugen, führe einerseits nicht nur zur sozialen Kohäsion innerhalb einer sozialen Gruppe, sondern auch zu Ausprägungen sozialer Kohäsion zwischen Personen, deren Beziehungen bzw. Vergemeinschaftungen nicht auf Interaktionsnähe und praktischer Kenntnis beruhen und andererseits zu Differenzierungsformen sozialer Gruppen, die auf der „Distinktionspraxis“ (Vester 2001: 228) der Akteure beruhen. Das Milieukonzept reagiert damit auf eine Verengung des Phänomens der Kohäsion sozialer Gruppen auf die klassifizierbare Differenzierung von Ständen, Schichten, Klassen und sozialer Lagen – mithin auf die Abbildbarkeit der Unterschiede von Lebensstilen auf sozialstrukturelle Bedingungen.

Wie erkennen sich Gleiche in der Welt?

Publisher: name: Zeitschrift für Theoretische Soziologie
Year: 2014

description: Die Ursprünge des Milieubegriffs lassen sich in Anlehnung an den Berliner Künstler Heinrich Zille kurz als „Zille sein Milljöh“ umreißen. Seine Zeitgenossen dachten an Arbeiterviertel, in denen arme Menschen auf engstem Raum zusammenlebten, in denen sich soziale Netzwerke, Vereine und eine auf Solidarität unter Gleichen gegründete Moral entwickelt hatten. Menschen in diesen „Milljöhs“ kannten und verstanden sich; im Außenverhältnis waren sie marginalisiert. Wenn man den Milieubegriff so auffasst, so bezeichnet er eine Gemeinschaftsbildung, die auf einer geteilten Position in der Sozialstruktur beruht. Das Milljöh ergänzt den Begriff der „Klasse für sich“ auf der Mesoebene des Sozialen. Es verwundert nicht, dass der Milieubegriff seither aus der Mode gekommen ist. Schon die Debatte über das „Jenseits von Klasse und Stand“ (Beck 1983; Geißler 1996) machte deutlich, dass Klasse an und für sich nicht als einziges sozialstrukturell relevantes Gliederungsprinzip hoch differenzierter Gesellschaft herhalten kann. Dies stieß die Entwicklung abstrakterer Milieubegriffe an (Hradil 1987; Vester 1997, in diesem Band), aber letztlich kam die Sozialstrukturanalyse davon ab, nach Gemeinschaftsbildung in gleicher Lebenslage zu suchen. In einem der reichsten Länder der Welt wird die Suche nach „Milljöhs“ zu einem Spezialthema, das sich auf stadtsoziologische Arbeiten zu Segregation oder kultursoziologische Analysen von Szenen beschränkt.

description: Thin films of ferrimagnetic Mn$_4$N are candidate materials to host magnetic skyrmions that have demonstrated thermal stability up to 450$^\circ$C. However, there are no experimental reports observing skyrmions in this system. Here, we discuss the results of sputter grown 15-17~nm Mn$_4$N thin films on MgO substrate capped with Pt$_{1-x}$Cu$_{x}$ layers. Vibrating sample magnetometry measurement of out-of-plane hysteresis loops confirmed that magnetic properties are insensitive to the cap layer composition. Imaging based on magnetic force microscopy measurements observed 300 to 50~nm sized skyrmions, as the Cu concentration was increased from $x$ = 0 to 0.9. We performed density functional theory calculations and found that the interfacial Dzyaloshinskii-Moriya interactions (iDMI) follow a trend: Mn$_4$N/MgO(001) $

description: Wer von sozialen Milieus reden will, der darf von der Gesellschaft nicht schweigen: wenn man soziale Milieus „verstehen“ will, muss man bereits die Gesellschaft begreifen, denn ihre Struktur gibt dem Aufbau und den Innenverhältnissen von Gruppen Bedeutung, Funktionen, Spielraum und Ressourcen; aber wer die Gesellschaft begreifen will, der muss „ihre“ Milieus verstehen, denn Strukturen oder Differenzierungsmuster entfalten ihre Wirkung auf das situierte Handeln zumeist durch die milieuspezifischen Selektions-Filter der Interpretation und der Übersetzung hindurch. Darin liegt, ganz der Sache angemessen, die Andeutung einer zirkulären epistemologischen Lage. Auch wenn sich Milieus und Gesellschaft gewiss nicht nach dem Muster der Beziehung zwischen Ganzem und Teil zueinander verhalten (weil z. B. die Differenzierung der Weltgesellschaft nicht nach dem „Dekompositions-Prinzip“ verfährt, siehe: Luhmann 1975 und 1997 sowie Schimank 1996), so stößt die Analyse doch auf das Problem des hermeneutischen Zirkels. Hier gibt es keine Hilfe durch den Kunstgriff einer vergleichsweise willkürlichen Festlegung von „abhängigen“ und „unabhängigen“ Variablen. Denn bei zirkulären Konstitutionsbeziehungen sind unreflektierte Festlegungen der analytischen Einstiegsprämissen der Königsweg zur Produktion methodisch induzierter Artefakte. Diese Zirkularität wäre auf den ersten Blick nicht mal ein großes Malheur, zumal die Milieuanalyse die Maxime einer „verstehenden“ Soziologie, erst komme die Sinndeutung und dann die Erklärung, in breiter Front als Verpflichtung zu einer hermeneutischen Methode auslegt, und bei diesem Geschäft drängt sich der hermeneutische Zirkel ganz von allein auf (Soeffner 1999 und Giddens 1984).

A study of submerged gas jets injected horizontally into liquid metals
Creators: name: Oryall, Gregory N.
Publisher: name: University of British Columbia

description: The physical characteristics of a submerged air jet injected horizontally into a bath of mercury were studied under isothermal, non-reactive conditions for nozzle diameters of 0.325 cm. and 0.476 cm. and over a range of modified Froude numbers with values from 20 to 300. A specially-designed electro-resistivity probe allowed the measurement of gas volume fraction and bubble frequency at all points within the jet. The distribution of these values has been expressed as a series of contour maps on a grid-sequence of orthogonal planes. Jet cone angle, diameter, and penetration distances were measured and compared to values obtained under similar conditions in the air-water system. The events occurring in the development of a submerged gas jet in a liquid were studied by means of highspeed cinematic photography in the air-water system. Mathematical models predicting jet behaviour have been examined in the air-mercury system and the extrapolation of experimental results to industrial copper converting and steelmaking operations has been discussed.

description: In diesem Beitrag soll geklärt werden, welchen Erkenntnisgewinn die Analyse sozialer Milieus für die Sozialstrukturanalyse, genauer eine sozioökonomisch orientierte Sozialstrukturforschung liefern kann. In der Frage wird bereits deutlich, dass nicht in erster Linie die Milieuforschung im Zentrum steht; den Ausgangspunkt bildet die Sozialstrukturanalyse und das Interesse, sozioökonomische Differenzierungen und die damit verbundenen Praktiken und Symbolwelten in ihrer Produktion und Reproduktion zu analysieren. In dem Beitrag wird drei Fragen nachgegangen: Was wird in der Soziologie/ Sozialstrukturanalyse unter sozialen Milieus verstanden? Auf welcher Wirklichkeits- bzw. Konstruktebene wird von Milieus gesprochen? Was bringt dieses Wissen um soziale Milieus für die Sozialstrukturanalyse?

description: We investigate the role of environment on star-formation rates of galaxies at various cosmic densities in well-studied clusters. We present the star-forming main sequence for 163 galaxies in four EDisCS clusters in the range 0.4 $$ 10$^{9.75}$M\textsubscript{\(\odot\)} show little dependence on environment. At face value, the similarities in the star-formation rate distributions in the three environments may indicate that the process of finally shutting down star formation is rapid, however, the depth of our data and size of our sample make it difficult to conclusively test this scenario. Despite having significant H$α$ emission, 21 galaxies are classified as {\em UVJ}-quiescent and may represent a demonstration of the quenching of star formation caught in the act.

description: Abstract:

Communication skills are vital in medical education as they facilitate effective interactions between healthcare providers and patients.

Objectives: To evaluate the effect of flipped classrooms in teaching communication skills to first-phase MBBS students in a medical college in eastern India.

Methodology and Participants: This study was carried out among two hundred Phase I MBBS learners after obtaining institutional ethical clearance and informed consent from the participants. Five faculty members of the Department of Physiology acted as facilitators for the sessions. A module was prepared and validated by senior faculty members of the same department. Four interactive face-to-face (two hours each) sessions were conducted for the students and the rest interactions were done using WhatsApp groups. Students were divided into 10 groups with 20 students in each group according to class roll numbers.

Results: Assessment of communication skills during the contact sessions was done by facilitators and peers using the Gap-Kalamazoo communication skill assessment form and results showed that the participants performed between fair to very good in all the 9 items. The participants did best in the following three items of the assessment scale: Opens the discussion; Gathers information; Demonstrates empathy. Pre-test score of MCQ exam: 41.35 ± 2.14 vs. Post-test score of MCQ exam: 81.4 ± 4.12; P value: <0.01** (highly significant). Students were satisfied with the knowledge and skills they had acquired and this module motivated them to join similar classes in the future, this is as per responses received in the feedback survey and on analysis of reflections.

Conclusions: The learners and participants were satisfied with the method of teaching communication skills using flipped classes in the early phase of the MBBS curriculum. The potential for students to exercise newly acquired skills in a real-world setting was the most favored and the most effective method of teaching-learning communication. Self-reflection consolidated learning success.

Soziale Milieus mit Migrationshintergrund

description: So, wie die politische Soziologie Pierre Bourdieus immer wieder auf die rekursiven und herrschaftsstabilisierenden Zusammenhänge sozialer und kognitiver Strukturen verweist, geht auch der nachfolgend exemplarisch vorgestellte Milieuansatz von der lebensweltlichen Integration von Struktur und Handlung aus. Er richtet sich auf die Zusammenhangsstruktur unterschiedlichster Merkmale, in denen gesellschaftliche Akteure ihr Leben gestalten und dabei spezifische soziale Syndrome entwickeln (vgl. Vester et al. 2001). Theodor Geiger spricht dabei von „Mentalitäten“ (Geiger 1932: 77 f.), Pierre Bourdieu von Dispositionen des „Habitus“ (Bourdieu 1987: 730 f.). Beide verbinden damit akteursspezifische Muster der Handlungsorientierung, aus denen heraus die Wahrnehmung und Gestaltung von Welt erfolgt. Habitus umfasst die Dimensionen des Geschmacks und des Lebensstils, der körperlichen und emotionalen Haltung, der Muster sozialer Praxis und Beziehungen und bezeichnet die allgemeine Grundhaltung eines Akteurs gegenüber der sozialen Welt. Er kann als Syndrom und Schema von praktischen und moralischen Einstellungs-, Klassifikations- und Wertmustern gefasst werden. Wenn der Habitus der Akteure sich in familialen, beruflichen, territorialen und anderen Gruppen ausbildet und seinerseits wieder die Beziehungen in den sozialen Gruppen mit strukturiert, liegt es nahe, diesen Zusammenhang in einem Konzept auszudrücken, das diese verschiedenen lebensweltlichen Ebenen und Felder miteinander verknüpft. Dies leistet das Konzept des sozialen Milieus. Soziale Milieus lassen sich als Beziehungszusammenhänge sozialer Gruppen verstehen, die durch typische Lebensweisen und durch ähnliche äußere Lebensbedingungen und innere Lebensgestaltung charakterisiert sind und sich voneinander abgrenzen. Sie basieren auf ähnlichen Dispositionen des Habitus.

description: Let F be a family of holomorphic functions and let K be a constant less than 4. Suppose that for all f in F the second iterate of f does not have fixed points for which the modulus of the multiplier is greater than K. We show that then F is normal. This is deduced from a result about the multipliers of iterated polynomials.

High temperature creep deformation in solid solution alloys of lead

description: Some high temperature creep properties of two alloy systems, Pb-Bi and Pb-In, have been studied. Three compositions in each system were used with all alloys being solid solutions at the deformation temperature. Solid solutions are usually divided into two groups, Class I and Class II, because of differences in certain creep properties. Attempts were made to classify the six alloys on the basis of the stress dependence of the steady state strain rate. Emphasis was also placed on the transient strain rate behaviour. Both initial transients from application of the load to attainment of steady state and transients in response to small increases or decreases in stress were studied as functions of stress, temperature and solute content. Significant differences were found in the shapes of the transients between the two alloy systems at some stresses and temperatures. These differences did not always coincide with the classification based on the steady state strain rate results. In Class I alloys, the glide of dislocations is usually considered as controlling the deformation, whereas in Class II dislocation climb is the recognized controlling mechanism. Two commonly accepted glide and recovery theories were evaluated for the present alloys but were found inadequate for some of the results. Two more recent theories of creep, the combined glide-recovery theory and the rearrangement theory, provided better theoretical characterizations for the two classes of alloy.

description: Energy transfer to acoustic phonons is the dominant low-temperature cooling channel of electrons in a crystal.For cold neutral graphene we find that the weak cooling power of its acoustical modes relative to the heat capacity of the system leads to a power law decay of the electronic temperature when far from equilibrium. For heavily doped graphene a high electronic temperature is shown to initially decrease linearly with time at a rate proportional to n^(3/2) with n being the electronic density. We discuss the relative importance of optical and acoustic phonons to cooling.

description: This paper investigates numerically the hydraulic conveying of solids through a 90$^{\circ}$ elbow that changes the flow direction from horizontal to vertical, in the very-narrow case where the ratio of pipe to particle diameters is less than 5. We performed resolved CFD-DEM (computational fluid dynamics - discrete element method) computations, in which we made use of the IB (immersed boundary) method of the open-source code CFDEM. We investigate the effects of the water flow and particle injection rate on the transport rate and sedimentation by tracking the granular structures appearing in the pipe, the motion of individual particles, and the contact network of settled particles. We found the saturated transport rate for each water velocity and that a large number of particles settle in the elbow region for smaller velocities, forming a crystal-like lattice that persists in time, and we propose a procedure to mitigate the problem.

description: Gliomas are the most common primary brain tumours. Despite advances in surgical techniques, postoperative supportive care, radiation and adjuvant systemic therapy, the life expectancy of patients with high grade glioma has remained essentially poor. Furthermore differential diagnosis among astrocytomas, oligodendrogliomas and oligoastrocytomas is very challenging and subject to inter-observer variability.
The purpose of the research was: 1) to investigate a series of high grade and low grade gliomas at gene and protein (immunohistochemistry) levels to disclose possible genetic portraits of malignancy; 2) to verify the utility of Nogo-A, Olig-2 and synaptophysin in providing a correct histological diagnosis of oligodendroglioma and to investigate a possible complementary role in selecting the best areas suitable for detecting 1p/19q codeletion using FISH analysis; 3) to study the role of microRNA in high grade gliomas. In order to obtain these goals large series of brain tumors were studied with DNA microarrays, immunohistochemistry and RT-PCR 
The results demonstrated that:
- Overexpression of IGFBP-2 and CDC20 is highly related to glioblastomas and their immunopositivity can be useful for the identification of glioblastoma in small biopsies.
- Nogo-A is the most useful and specific marker in differentiating oigodendrogliomas from other gliomas. Furthermore, using a Nogo-A driven FISH analysis, it is possible to identify a larger number of 1p19q codeletions in gliomas.
- microRNAs can be studied in paraffin embedded tissues better than in fresh tissues. A series of six microRNA, significatively deregulated in glioblastomas, may represent a genetic signature with prognostic and predictive value and could constitute candidates for novel anti-cancer therapeutics.
