title: Analysis and behaviour of structural concrete reinforced with sustainable materials

description: Fibre reinforced polymer (FRP) composites have extensive applications in various fields such as the aerospace and automotive engineering industries. In recent years, there have been more novel applications for FRP in the construction industry. FRP is known for its beneficial properties such as high strength to weight ratio, lower specific weight and excellent corrosion and fatigue resistance. These advantages have made FRP more desirable to be used as an alternative to steel reinforcement for internal as well as external reinforcement in structural concrete, especially those which are exposed to extreme environments. One of the objectives of this research is to identify all the different types of fibre reinforced polymer such as CFRP, GFRP and BFRP. These all can be used as an alternative to conventional steel reinforcement in structural concrete. For each type their physical and mechanical properties such as tensile strength, modulus of elasticity, ultimate strain, durability in alkaline environments, fatigue strength and bond strength has been identified. This thesis also presents the results of experimental, analytical and numerical modelling investigations of the performance and behaviour of concrete members reinforced with basalt fibre reinforced polymer (BFRP). The primary objective of this research is to address the applicability of this material as internal reinforcement and to investigate the applicability of current FRP design guides on BFRP as an internal reinforcement to structural concrete members. For the flexure investigation of BFRP reinforced concrete sections, four beams were studied, two of them being BFRP reinforced beams and two of them being conventional steel reinforced beams that have been used as control beams. The outcome of this has shown us different types of FRP bars that can replace the traditional steel reinforcement in concrete structures. Also it provides us with detailed knowledge of the behaviour of materials such as BFRP bars. Moreover, it determines the applicability of current FRP design guidelines on BFRP reinforcements.

description: Kinderbücher werden häufig vonseiten des Literaturbetriebs für zwei traditionelle Geschlechter eingeteilt und vermarktet: Es gibt weiterhin Mädchen- und Jungenbücher. Inwiefern das Gendermarketing von Kinderbuchverlagen in der Literaturkritik aufgegriffen wird, ist Gegenstand der vorliegenden Masterarbeit. Analysiert werden über 470 Besprechungen eines Primärliteraturcorpus, bestehend aus 18 Titeln der aktuellen deutschsprachigen Kinderliteratur. Neben dem literaturwissenschaftlichen semiotischen Analyseinstrument von sechs Genderdimensionen nach Hans Krah kommen interdisziplinäre Ansätze der Gender Studies sowie Erkenntnisse der (Werbe-)Psychologie und der Marktforschung zum Tragen. Die Titel des Corpus, das anhand von Bestsellerlisten ausgewählt wurde, sind hauptsächlich Serienromane und werden in der professionellen Kinderliteraturkritik (der Printmedien) kaum wahrgenommen und besprochen, zahlreich jedoch in Onlinemedien von laienhaften Kritiker:innen, besonders auf Bücherblogs und Buch-Community-Seiten sowie in den Kommentarfunktionen von Onlinehändler:innen. Hierbei werden an erster Stelle Empfehlungen auf Basis des eigenen Leseverhaltens ausgesprochen. Geschlechts-adressierungen fallen meist eindeutig für Mädchen oder Jungen aus, während auf Geschlechterrollen oder das Gendermarketing der Verlage kaum eingegangen wird. Kinderliteraturkritik hat auch für öffentliche Bibliotheken, die als literaturvermittelnde Institutionen eine wichtige Rolle im Handlungssystem der Kinderliteratur einnehmen, große Bedeutung für das Bestandsmanagement. Die Titel des Untersuchungscorpus werden zum größten Teil vom Lektorratsservice besprochen. In den Rezensionen wird auf die Adressierungen und die Eignung in den Bibliotheken eingegangen, allerdings auf eine Weise, die (Geschlechts)Stereotype reproduziert. Geschlecht findet außerhalb der Kund:innenadressierung keinen Platz in der Kritik, da von vornherein klar zu sein scheint, dass es Kinderbücher eindeutig für Mädchen oder Jungen gibt. Die Tendenz zur dichotomen Geschlechtseinteilung wird im Rezensionswesen der öffentlichen Bibliotheken und schließlich durch die Indexierung im Katalog eher verstärkt als aufgebrochen. Die Ergebnisse der Arbeit verdeutlichen somit die tief verankerte und beharrliche Zweiteilung von Kinderliteratur in zwei Geschlechter.

description: The theoretical construction of a traversable wormhole proposed by Morris and Thorne maintains complete control over the geometry by assigning both the shape and redshift functions, thereby leaving open the determination of the stress-energy tensor. This paper examines the effect of introducing the linear barotropic equation of state $p_r=ωρ$ on the theoretical construction. If either the energy density or the closely related shape function is known, then the Einstein field equations do not ordinarily yield a finite redshift function. If, however, the wormhole admits a one-parameter group of conformal motions, then both the redshift and shape functions exist provided that $ω

description: Rigid bodies, plastic impact, persistent contact, Coulomb friction, and massless limbs are ubiquitous simplifications introduced to reduce the complexity of mechanics models despite the obvious physical inaccuracies that each incurs individually. In concert, it is well known that the interaction of such idealized approximations can lead to conflicting and even paradoxical results. As robotics modeling moves from the consideration of isolated behaviors to the analysis of tasks requiring their composition, a mathematically tractable framework for building models that combine these simple approximations yet achieve reliable results is overdue. In this paper we present a formal hybrid dynamical system model that introduces suitably restricted compositions of these familiar abstractions with the guarantee of consistency analogous to global existence and uniqueness in classical dynamical systems. The hybrid system developed here provides a discontinuous but self-consistent approximation to the continuous (though possibly very stiff and fast) dynamics of a physical robot undergoing intermittent impacts. The modeling choices sacrifice some quantitative numerical efficiencies while maintaining qualitatively correct and analytically tractable results with consistency guarantees promoting their use in formal reasoning about mechanism, feedback control, and behavior design in robots that make and break contact with their environment.
title: Digitale Kompetenzen von Lehrkräften im Fach Mathematik

description: Lehrkräfte waren vor allem in den letzten beiden Jahren hinsichtlich ihrer digitalen Kompetenzen gefordert. Aufgrund von Lockdowns mussten Lehrpersonen die Herausforderung annehmen und ihren Schüler*innen Übungsmaterial auf digitalem Weg zukommen lassen oder generell Unterrichtsstunden online über verschiedene Plattformen halten. Digitale Medien gewinnen immer mehr an Bedeutung. Sie dringen immer mehr in den beruflichen sowie in den privaten Kontext ein. Die vorliegende Arbeit beschäftigt sich mit den digitalen Kompetenzen von Lehrkräften im Fach Mathematik. Konkret stellt sich die Frage nach dem Aufbau digitaler Kompetenzen für Lehrpersonen der Sekundarstufe I und II, mit denen sich die Herausforderungen der Digitalisierung bewältigen lassen. Das Ziel dieser Arbeit ist es, herauszufinden, wie vertraut Lehrpersonen mit digitalen Medien sind und wie sie persönlich ihre Kompetenzen dahingehend einstufen. Um die Forschungsfragen, welche in Kapitel 1.2 angeführt werden, beantworten zu können, wurde eine empirische Untersuchung mithilfe eines Fragebogens durchgeführt. Der Fragebogen wurde online über die Plattform „SoSci Survey“ angefertigt. Anschließend wurde ein Link dazu erstellt und über diverse Social Media Plattformen mit Lehrkräften, die das Fach Mathematik unterrichten bzw. unterrichtet haben, geteilt. 80 Personen haben an dieser Umfrage teilgenommen.
description: In the last two years teachers have been challenged regarding their digital skills. Due to lockdowns, teachers had to accept the challenge and send their students exercise material digitally or generally teach online via various platforms. Digital media is becoming increasingly important in both professional and private contexts. This thesis deals with the digital skills of teachers in mathematics. Specifically, the question arises how digital skills can be built up for teachers to meet the challenges of digitization. The aim of this thesis is to find out how familiar teachers are with digital media and how they rate their personal skills regarding digitization. To answer the key questions, which are cited in chapter 1.2, an empirical study was carried out using a questionnaire. The questionnaire was prepared online via the platform "SoSci Survey". Afterwards a link was created and shared via various social media platforms with teachers who teach or have taught mathematics. 80 people took part in this survey.

description: Die vorliegende Arbeit setzt sich mit dem Einsatz von Musik im DaF-Lehrwerk Menschen (B1) für Erwachsene und junge Erwachsene auseinander. Sie erforscht für welche Lernziele die 8 Lieder im Kursbuch verwendet werden und dabei insbesondere, inwieweit ästhetisches und kulturreflexives Lernen erzielt werden. Für diese Zwecke wird die kriteriengeleitete Lehrwerkanalyse als qualitative Forschungsmethode gewählt. Der Theorieteil stellt zunächst einen Zusammenhang zwischen Kultureller Bildung und dem Gemeinsamen europäischen Referenzrahmen (GeR) her und skizziert die Potenziale von Musik für das Sprachenlernen und deren Einsatz in DaF-Lehrwerken. Zudem gibt er Einblick in die angewandte Lehrwerkforschung, -analyse und -kritik und bildet die Grundlage für den Kriterienkatalog. Die Ergebnisse der kriteriengeleiteten Analyse zeigen, dass die Lieder im Kursbuch Menschen (B1) zur Förderung der Fertigkeiten Hören und Lesen eingesetzt werden und vorwiegend der Wiederholung grammatikalischer Strukturen dienen. Ferner stellt sich heraus, dass der Einsatz der Lieder kaum den Ansprüchen ästhetischen Lernens gerecht wird und diese somit keinen Beitrag zur Kulturellen Bildung leisten. Die Lernaktivitäten zu den Liedern weisen zudem keine kulturreflexive Ausrichtung auf.

Creators: name: Dressler, Melinda

description: Die folgende Arbeit beschäftigt sich mit dem Einfluss und der Wirkung von Rabattcodes auf der Plattform Instagram. Der Fokus lag vor allem auf der Untersuchung, inwiefern das Bewerben von Produkten mit Hilfe von Rabattcodes von Influencer*innen einen Effekt auf die Wahrnehmung der Produktqualität und das Kaufverhalten der Social-Media-Nutzer*innen hat. Dabei wurde auch auf die Auswirkungen von unterschiedlich hohen Rabatten eingegangen. Mit Hilfe einer quantitativen Online-Befragung haben 205 Personen zwischen 18 und 35 Jahren an der Studie teilgenommen. Das Design setzte sich aus einer experimentellen Manipulation mit einer Kontrollgruppe und zwei Versuchsgruppen zusammen. Die Ergebnisse belegen einen negativen Einfluss von Rabattcodes, der eine geringere Kaufwahrscheinlichkeit und eine schlechtere Qualitätswahrnehmung der beworbenen Produkte im Vergleich zu Artikeln ohne Preisreduzierungen zur Folge hat. Niedrige und hohe Rabattcodes unterscheiden sich nicht in ihrer Wirksamkeit. Das Alter, das Geschlecht und die Bildung der Instagram-User*innen wirken sich nicht signifikant auf den Effekt von Influencer*innen-Rabatten auf die Wahrnehmung der Qualität und den Kauf der Produkte aus. Die Beurteilung der Influencer*innen ist in diesem Zusammenhang von hoher Bedeutung und kann abhängig von der Wahrnehmung die Qualitätsbewertung und das Kaufverhalten erhöhen oder reduzieren.
description: The following work deals with the influence and effect of discount codes on Instagram. The main focus was on investigating the extent to which the promotion of products with the help of discount codes from influencers has an effect on the perception of product quality and buying behavior of social media users. The effects of different discounts were also discussed. 205 people between the ages of 18 and 35 took part in the study with the help of a quantitative online survey. The design consisted of an experimental manipulation with a control group and two experimental groups. The results show that discount codes have a negative impact, resulting in a lower probability of purchase and a worse quality perception of the advertised products compared to no price reductions. Low and high discount codes do not differ in their effectiveness. The age, gender and education of Instagram users have no significant impact on the effect of discounts on the perception of the quality and the purchase of the products. The evaluation of the influencers is very important in this context and can increase or reduce the quality rating and purchasing behavior depending on their rating.

description: The growth of Bi on Ag(111) induces different surface structures, including(√3×√3)R30°surface alloy, Bi-(p×) overlayer and Bi(110) thin film as a function of increasing Bi coverage. These structures have been studied using low-temperature scanning tunneling microscopy, low-energy electron diffraction, ab initio calculations and photoemission spectroscopy from core-levels and valence bands at room temperature. At 1/3 of a monolayer of Bi on Ag(111) leads to the formation of BiAg2 surface alloy with a long range ordered (√3×√3)R30° superstructure. A detailed analysis of this structure using LEED I-V measurements together with DFT calculations is presented. The Bi atom is found to replace one top layer Ag atom in each unit cell, forming a substitutional BiAg2 surface alloy. This mode of accommodation of Bi was found to be energetically favourable based on ab initio total-energy calculations. Based on photoemission spectroscopy we find the sp-derived Shockley surface state on Ag(111) is rapidly quenched upon deposition of Bi, due to the strong variation of inplane surface potential in the Ag2Bi surface alloy. The core levels of Bi 4f of the (√3×√3)R30° Ag2Bi alloy and Bi(110) thin film are shifted to lower binding energy by ~0.6 eV and ~0.3 eV compared with the Bi bulk value, respectively. Mechanisms inducing the core level shifts are discussed as due to a complex superposition of several factors. At coverage above a critical value of 0.55 monolayers, the Ag2Bi alloy phase gradually converts into an ordered Bi (p × √3) overlayer structure supported on Ag(111). We postulate that the dealloying transition is likely driven by compressive strain induced by incorporation of large-size Bi atoms into Ag at a high coverage and the subsequent lack of miscibility of Ag and Bi bulk phases. After completion of the dealloying process, Bi(110) thin films can be grown epitaxially on top of Ag(111) with a chemically abrupt interface. The deposition of 1/3 of a monolayer of Pb on Ag(111) leads to the formation of Ag2Pb surface alloy with a long range ordered (√3x√3)R30° superstructure. A detailed analysis of this structure using LEED I-V and MEIS measurements together with DFT calculations is presented. Quasicrystals, materials with aperiodic long-range order, are usually formed by at least two elements with a specific chemical composition. In this study, we demonstrate that, a single element multilayer quasicrystal can be formed on a template. Using a hitherto unexplored quasicrystalline substrate, the icosahedral Ag-In-Yb quasicrystal, and various experimental techniques including scanning tunneling microscopy combined with theoretical calculations of adsorption energies, we identify the initial adsorption sites for Pb atoms on the substrate and hence deduce the multilayer structure of the Pb overlayer. We propose a mechanism for the growth of epitaxial materials on the quasicrystalline substrate.

description: Accommodating both a 126 GeV mass and Standard Model (SM) like couplings for the Higgs has a fine tuning price in supersymmetric models. Examples are the MSSM, in which SM-like couplings are natural, but raising the Higgs mass up to 126 GeV requires a considerable tuning, or the NMSSM, in which the situation is reversed: the Higgs is naturally heavier, but being SM-like requires some tuning. We show that models with non-decoupling D-terms alleviate this tension - a 126 GeV SM-like Higgs comes out basically with no fine tuning cost. In addition, the analysis of the fine tuning of the extended gauge sector shows that naturalness requires the heavy gauge bosons to likely be within the LHC run II reach.

title: Brand anthropomorphism : the literary lives of marketing mascots
Creators: name: Khogeer, Yusra
Publisher: name: University of Liverpool Repository

description: There is no end to the brands that lend themselves to anthropomorphic comparison. As an area under researched, the ultimate aim of this thesis is to improve our understanding of the phenomenon of brand anthropomorphism via focusing on one of the most prominent tactics currently being used by industry – the use of marketing mascots. This research begins by theoretically positioning the topic in a rich body of literature. Drawing on branding literature, the multidimensional nature of brands is explored as a starting point for understanding brand mascots. The fundamental theories referred to are integrated to form the Brand Puzzle. Next, the phenomenon of anthropomorphism is examined by referring to literatures from the disciplines of anthropology, animal behaviour, English literature and religion. To complete the extensive literature review, this thesis draws on marketing, advertising, psychology and consumer behaviour literature to reveal any existing classifications for brand anthropomorphism prior to introducing a new typology. Additionally, an investigation into the use of mascots is carried out paying particular attention to their conceptual development and their ‘humanity’. By designing an interpretive case study methodology that relies on a variety of research techniques, including netnography, interviews and photo-essays, as well as a provocative style of presentation, this thesis sets out firstly to explore the development of three marketing mascots on the social media site of Facebook: Aleksandr Orlov mascot for price comparison website CompareTheMarket.com; The M&M’s Spokescandies mascots for Mars’ M&M’s chocolate; and Mr Peanut mascot for Planters peanuts. A literary approach was adopted when tackling this mysterious process of creating marketing mascots. Secondly, this thesis sets out to analyse consumer engagement with the brands via their engagement with the selected marketing mascots. Six forms of consumer engagement were identified which were perceived to have an effect on the narrative of marketing mascots. The discussion section of this thesis creatively links the empirical evidence presented in the findings chapters and the insights from the literature with novels, storytelling and genre reading. The prominence of these have led to the development of a Literary Wheel model that has scope for use by industry and offers a direction for future research. In conclusion, this research contributes to knowledge in the field of brand anthropomorphism. It provides a formula for the creation of captivating marketing mascots that fulfil the needs of our increasingly communication hungry culture, encouraging elevated consumer engagement and the development of stronger consumer-brand relationships.
title: Ecopolitical transformations and the development of environmental philosophical awareness in science fictional narratives of terraforming
Creators: name: Pak, Christopher
Publisher: name: University of Liverpool Repository
Year: 2013

description: This thesis examines the motif of terraforming from Wells’ War of the Worlds (1898) to James Cameron’s film Avatar (2009) in order to assess the dialogical development of ecological themes and its imbrication with politics in science fictional narratives of terraforming. It tracks the growth of the theme in four distinct phases that are contextualised by a short history of terraforming in the introductory first chapter. Chapter two examines the appearance of proto-terraforming and proto-Gaian themes in British scientific romance and American pulp sf prior to Jack Williamson’s coining of the term “terraform” in 1942. Environmental philosophical concepts of nature’s otherness, Lee’s Asymmetry, Autonomy and No-Teleology Theses and notions of identification with nature are examined in this connection to illustrate the character of these texts’ engagement with environmental philosophy and ecopolitics. Chapter three examines the development of the terraforming theme in primarily American 1950s terraforming stories and explores how the use of elements of the American Pastoral are deployed within the discourse of sf to consider the various ways in which the political import of terraforming is imagined. Chapter four explores the impact of the environmental movement of the 1960s in terraforming stories of the 1960s-1970s. Beginning with a consideration of the use of Gaian images in characterisations of alien ecologies, this chapter then progresses to consider a parallel strand of terraforming stories that transform the themes of the 1950s texts in the light of the impact of the 1960s environmental movement. Chapter five concludes this analysis by considering two major trilogies of terraforming written in the 1980s-1990s, Pamela Sargent’s Venus and Kim Stanley Robinson’s Mars trilogies. These works inherit the discourse of terraforming established by earlier works and re-configure them in ways that address contemporary environmental and geopolitical concerns.

description: We consider here special Poisson brackets given by the "averaging" of local multi-dimensional Poisson brackets in the Whitham method. For the brackets of this kind it is natural to ask about their canonical forms, which can be obtained after transformations preserving the "physical meaning" of the field variables. We show here that the averaged bracket can always be written in the canonical form after a transformation of "Hydrodynamic Type" in the case of absence of annihilators of initial bracket. However, in general case the situation is more complicated. As we show here, in more general case the averaged bracket can be transformed to a "pseudo-canonical" form under some special ("physical") requirements on the initial bracket.

title: Quantum effects and novel physics in rotating frames
Creators: name: Cromb, Marion
Publisher: name: University of Glasgow
Year: 2023

description: The birth of quantum physics and general relativity were two revolutions in physics. But a century later, scientists have not yet united the two theories. Attempts to combine them are mostly theoretical; controlled experiments have historically been neglected due to the comparative weakness of gravity and the corresponding precision or extreme scales assumed needed to test quantum gravity effects. We take a new approach, inspired by Einstein’s equivalence of gravitational fields and accelerated frames. Non-inertial frames can be controlled in the lab, and allows us to experimentally test new frame-dependent effects and already-established quantum effects in new regimes. This frame-dependence is fundamentally interesting by itself, but also provides parallels to curved spacetime effects. To that effect, I have carried out experiments in rotating frames and shown new effects. I have combined mechanical rotation with acoustics, sending sound waves through a rotating absorber. With this, I was the first to show experimental proof of the Zel’dovich effect: the amplification of waves carrying angular momentum by a rotating object. It is theorised the Zel’dovich effect should also generate electromagnetic waves out of the quantum vacuum, however the conditions are much harder to meet. I have also done optics experiments to show how rotation can affect quantum entanglement. The Hong-Ou-Mandel effect was used as a witness for antisymmetric entanglement between photons. The symmetry of frequency entangled photon pairs can be manipulated by introducing path superpositions and controlling their phase difference. Through experiment I established that to witness antisymmetry with the Hong-Ou-Mandel effect it was much easier in the regime where the superposed paths had path length differences outwith the single-photon coherence length. Within a rotating frame, a rotation-dependent phase difference between counterpropagating beams of light appears, called the Sagnac effect. Combining Sagnac interferometers with a Hong-Ou-Mandel interferometer on a rotating platform, I have shown how rotation can control the entanglement symmetry of photon pairs. The success of these experiments can be built on in future experiments exploring quantum effects in rotating frames and curved spacetimes. Identifying these effects has relevance in fundamental physics and to new technologies e.g. quantum communication, as it scales up to satellites in the curved spacetime around the rotating Earth.
Experimental investigations of automotive surface contamination

description: Sports Utility Vehicles are popular in the global automotive market due to their practicality. However, these geometries have a propensity to contamination of water and dirt that generates problems with visibility, driver assistance systems, lighting and customer dissatisfaction. Contamination issues tend to be discovered during prototype testing and are therefore expensive to resolve because the geometry is largely fixed. Identifying problems at an early stage in the design through numerical simulations would resolve many of the issues. To have confidence in the simulations they must be correctly initialised and validated objectively against experimental test cases.
An approach to quantifying surface contamination is identified for the first time and an extensive set of experimental controls determined. The approach uses an Ultra Violet dye to dope water and an Ultra Violet light to illuminate the fluid. The intensity of the emitted light from the dye is a function of the fluid thickness, illumination intensity and time. The approach is thoroughly explored and validated before being implemented in a pilot study that employs a quarter scale model of a simplified SUV and tested in a wind tunnel using a fully characterised spray to contaminate the base. The model base pressures and streamwise Particle Image Velocimetry planes of the wake are obtained and used alongside the results to identify mechanisms. The objective measure of mass deposition rate per area is calculated and compared to previously used measures to demonstrate its effectiveness.
Once deposited on the surface, wet contaminant forms drops, rivulets and thin films. These move across the surface of the car requiring wiper systems to maintainvisibility and management techniques to remove the contaminant. Uncontrolled flows can cause distractions to the driver and reduce the effectiveness of other systems such as cabin ventilation.
An essential requirement in currently available simulation methods for surface water flows is a representative contact angle model. The tilted plate method is used to obtain these at a range of Capillary numbers for different fluids and surfaces relevant to the topic. Model parameters for the simulations are identified and a novel validation method proposed.
This study demonstrates that fully characterised experiments and physical objective measures are absolutely essential to enable numeric simulations to be employed with the high levels of certainty demanded by the industry.

description: In this paper we introduce universal asymptotic unfolding normal forms for nonlinear singular systems. Next, we propose an approach to find the parameters of a parametric singular system that they play the role of universal unfolding parameters. These parameters effectively influence the local dynamics of the system. We propose a systematic approach to locate local bifurcations in terms of these parameters. Here, we apply the proposed approach on Hopf-zero singularities whose the first few low degree terms are incompressible. In this direction, we obtain novel orbital and parametric normal form results for such families by assuming a nonzero quadratic condition. Moreover, we give a truncated universal asymptotic unfolding normal form and prove the finite determinacy of the steady-state bifurcations for two most generic subfamilies of the associated amplitude systems. We analyze the local bifurcations of equilibria, limit cycles and the secondary Hopf bifurcation of invariant tori. The results are successfully implemented and verified using Maple. By employing the proposed approach, we design an effective multiple-parametric quadratic state feedback controller for a singular system on a three dimensional central manifold with two imaginary uncontrollable modes. We illustrate how our program systematically identifies the distinguished (universal unfolding) parameters, derives the estimated transition varieties in terms of these parameters, and locates the local primary and secondary bifurcations of equilibria, limit cycles and invariant tori. This approach is useful in designing efficient nonlinear feedback controllers (single or multiple inputs) for local bifurcation control in engineering problems.

description: Les bâtiments publics sont les bâtiments « dont les personnes publiques (État1, opérateurs de l’Etat et collectivités territoriales) sont propriétaires, qu’elles les occupent ou non » (Le Blog Immo, 2018). Ils représentent une part importante du parc immobilier français avec un total de 191.000 bâtiments en 2018 occupant une surface d’environ 99 millions de mètres carrés (Projet loi de finance, 2020) (Direction de l’Immobilier de l’Etat, 2018). Au niveau du tertiaire, Le parc public représente près du tiers du parc national (“La rénovation des bâtiments publics,” 2020). Au-delà de son ampleur, le patrimoine immobilier public est caractérisé par sa singularité sur plusieurs niveaux, ce qui peut représenter des contraintes quant à sa gestion. En effet, le parc immobilier public est caractérisé par (Lourdin, 2010) (Direction de l’Immobilier de l’Etat, 2018)…

Physician's Quick Guide: Oshtoran Syndrome (H63D Syndrome Type-3) - A Rare but Life-Threatening Condition
Creators: name: International H63D Syndrome Research Consortium
Publisher: name: Zenodo
Year: 2024

description: Oshtoran Syndrome, also known as H63D Syndrome Type-3, is a rare, potentially life-threatening multisystem disease characterized by a homozygous mutation of the HFE gene H63D. This quick guide provides essential information for physicians who may unexpectedly encounter patients with this condition. Key features include the accumulation of toxic non-transferrin-bound iron (NTBI), severe autonomic dysfunction, and variable innate immune system impairment. Patients often appear healthier than their actual condition, which can be misleading. The syndrome cannot be detected by standard laboratory tests or imaging. Treatment is highly individualized and includes careful pharmacological management, iron monitoring, and supportive therapies. This guideline emphasizes the critical importance of maintaining established treatments, as any changes can have fatal consequences. It also highlights the dangers of common iron reduction therapies in these patients and the need for immediate, stress-free medical attention to prevent life-threatening complications.

description: We introduce a new device in the study of abstract elementary classes (AECs): Galois Morleyization, which consists in expanding the models of the class with a relation for every Galois type of length less than a fixed cardinal $κ$. We show: $\mathbf{Theorem}$ (The semantic-syntactic correspondence) An AEC $K$ is fully $( \text{LS} (K)$. If $K$ is Galois stable, then the class of $κ$-Galois saturated models of $K$ admits an independence notion ($(

description: The harmonic numbers $H_n=\sum_{03$ be a prime. With helps of some combinatorial identities, we establish the following two new congruences: $$\sum_{k=1}^{p-1}\frac{\binom{2k}k}kH_k\equiv\frac13\left(\frac p3\right)B_{p-2}\left(\frac13\right)\pmod{p}$$ and $$\sum_{k=1}^{p-1}\frac{\binom{2k}k}kH_{2k}\equiv\frac7{12}\left(\frac p3\right)B_{p-2}\left(\frac13\right)\pmod{p},$$ where $B_n(x)$ denotes the Bernoulli polynomial of degree $n$. As an application, we determine $\sum_{n=1}^{p-1}g_n$ and $\sum_{n=1}^{p-1}h_n$ modulo $p^3$, where $$g_n=\sum_{k=0}^n\binom nk^2\binom{2k}k\quad\mbox{and}\quad h_n=\sum_{k=0}^n\binom nk^2C_k$$ with $C_k=\binom{2k}k/(k+1)$.

description: We review progress that has been made in utilizing one form of Direct Statistical Simulation (DSS) to describe geophysical and astrophysical flows that are anisotropic and inhomogeneous. We first explain the approach, which is based upon a systematic and conservative expansion of the equations of motion for low-order equal-time cumulants. We place the method into context with other statistical procedures. Truncation at second order in the hierarchy of cumulants is equivalent to retaining the interaction between zonal mean flows and eddies. Eddy-eddy interactions appear at higher orders, but care must be taken to keep the higher-order expansions realizable with non-negative probability distribution functions. The strengths and weaknesses of different levels of approximation are assessed with numerical experiments on the fiducial problem of a stochastically forced jet on a spherical surface. The results give an insight into the mechanisms that may control jet spacing and strength, and indicate interesting avenues for future research.

description: We study online scheduling problems on a single processor that can be viewed as extensions of the well-studied problem of minimizing total weighted flow time. In particular, we provide a framework of analysis that is derived by duality properties, does not rely on potential functions and is applicable to a variety of scheduling problems. A key ingredient in our approach is bypassing the need for "black-box" rounding of fractional solutions, which yields improved competitive ratios. We begin with an interpretation of Highest-Density-First (HDF) as a primal-dual algorithm, and a corresponding proof that HDF is optimal for total fractional weighted flow time (and thus scalable for the integral objective). Building upon the salient ideas of the proof, we show how to apply and extend this analysis to the more general problem of minimizing $\sum_j w_j g(F_j)$, where $w_j$ is the job weight, $F_j$ is the flow time and $g$ is a non-decreasing cost function. Among other results, we present improved competitive ratios for the setting in which $g$ is a concave function, and the setting of same-density jobs but general cost functions. We further apply our framework of analysis to online weighted completion time with general cost functions as well as scheduling under polyhedral constraints.
