description: We describe a lattice-gas model suitable for studying the generic effects of polydispersity on liquid-vapor phase equilibria. Using Monte Carlo simulation methods tailored for the accurate determination of phase behaviour under conditions of fixed polydispersity, we trace the cloud and shadow curves for a particular Schulz distribution of the polydisperse attribute. Although polydispersity enters the model solely in terms of the strengths of the interparticle interactions, this is sufficient to induce the broad separation of cloud and shadow curves seen both in more realistic models and experiments.

description: There is an increase in medical students with long term conditions applying for accommodations in assessment. Medical school responses to such applications appear inconsistent, possibly reflecting insufficient guidance for policy. We aimed to inform an approach by developing guidance. Within a New Zealand and Australian context, we used a four-stage action research methodology: discussion with medical educators and survey of all 21 medical schools, including responding to 22 hypothetical scenarios; developing an approach; applying the approach to the hypothetical scenarios; and seeking feedback from stakeholders on the proposed approach. Current practice varied among the 13 responding medical schools. Medical schools were consistent in their responses for 10 hypothetical scenarios but inconsistent in 12. An approach based on a matrix of authenticity to practice, including regulatory and employment factors, and feasibility to educational institutions was developed. This was applied to the hypothetical scenarios and highlighted how consistency could be better achieved, and where further discussion between regulators and employers might be needed. This approach and the matrix based on authenticity and feasibility provides guidance to consider assessment accommodation applications. It highlights the need for discussions among regulators, employers, educational institutions and the disability sector.

description: The problem of pollution of the soil environment with heavy metals is analyzed. Of particular importance is the profile migration of pollutants, which occurs most intensively in spring, autumn and summer with a large amount of precipitation, when there are intense descending flows of soil moisture. The migration of heavy metals is limited by the processes of their deposition on geochemical barriers. The study of the profile migration and accumulation of heavy metals showed that metals have an unequal behavior in soils, a change in their content along the profile is noted. The article examines the dynamics of the distribution of mobile forms of heavy metals in various soils of the Vinnitsa region, provides the results of determining the pH in these soils. It has been established that trace elements in the form of inorganic salts are effective on acidic soils. In soils with a reaction close to neutral, their effectiveness decreases tenfold. In neutral and slightly alkaline soils, inorganic salts cannot contain trace elements in a water-soluble form, that is, in a form accessible to plants, and their effectiveness tends to zero. Analyzing soil contamination with lead, cadmium, zinc and copper, it was found that their content was 8.1 times lower than the MPC, 5.38, 21.4 and 5.0 times, respectively. A high content of heavy metals in the soil was observed for zinc, compared with lead, cadmium and copper, it was 1.44, 8.23 and 1.78 times higher, respectively.

description: A central arrangement $\A$ of hyperplanes in an $\ell$-dimensional vector space $V$ is said to be {\it totally free} if a multiarrangement $(\A, m)$ is free for any multiplicity $ m : \A\to \Z_{> 0}$. It has been known that $\A$ is totally free whenever $\ell \le 2$. In this article, we will prove that there does not exist any totally free arrangement other than the obvious ones, that is, a product of one-dimensional arrangements and two-dimensional ones.

description: Η εργασιακή ικανοποίηση είναι σημαντικός παράγοντας για την συνολική ικανοποίηση από τη ζωή κάθε ατόμου, για την ποιότητα της επαγγελματικής ζωής των εργαζομένων, για την απόδοση και την οργανωτική τους δέσμευση (Moniarou et al. 2015) και σχετίζεται με την ψυχολογία ενός εργαζομένου. Ένας χαρούμενος και ικανοποιημένος εργαζόμενος σε μια εργασία, έχει πάντα κίνητρο να συνεισφέρει περισσότερο. Από την άλλη, ένας δυσαρεστημένος εργαζόμενος είναι ληθαργικός, κάνει λάθη και γίνεται βάρος για την εταιρεία-οργανισμό. Στην παρούσα έρευνα μελετάται η εργασιακή ικανοποίηση των Στελεχών του Λιμενικού Σώματος χρησιμοποιώντας την θεωρία των εργασιακών αξιών. Τα αποτελέσματα δείχνουν ότι οι επαγγελματίες του Λιμενικού Σώματος είναι γενικά ικανοποιημένοι με την δουλειά τους. Οι εξωτερικές αξίες και οι κοινωνικές είναι αυτές που επηρεάζουν σημαντικά την εργασιακή ικανοποίηση Στελεχών, με τη μονιμότητα της θέσης, τη σταθερότητα της εργασίας (εξωτερικές αξίες), τη σχέση των Στελεχών με τους συναδέλφους τους, τη συνεισφορά τους στην κοινωνική ευημερία και τη δυνατότητα που τους δίνει το επάγγελμα να βοηθάνε τους πολίτες (κοινωνικές αξίες) να συμβάλουν θετικά στην εργασιακή ικανοποίηση. Από την εξέταση του φύλου (άνδρες- γυναίκες) δεν βρέθηκε να υπάρχει σημαντική διαφορά ως προς την εργασιακή ικανοποίηση. Στην εξέταση της περίπτωσης ύπαρξης διαφορών ικανοποίησης ανά Σχολή προέλευσης των Στελεχών και των ετών υπηρεσίας ως προς τις εργασιακές αξίες δεν προέκυψαν στατιστικά σημαντικές διαφοροποιήσεις.

description: We investigate a planar heterostructure composed of two graphene films separated by a narrow-gap semiconductor ribbon. We show that there is no the Klein paradox when the Dirac points of the Brillouin zone of graphene are in a band gap of a narrow-gap semiconductor. There is the energy range depending on an angle of incidence, in which the above-barrier damped solution exists. Therefore, this heterostructure is a "filter" transmitting particles in a certain range of angles of incidence upon a potential barrier. We discuss the possibility of an application of this heterostructure as a "switch".

description: This Letter investigates the emergence of corner modes in elastic twisted Kagome lattices at a critical twist angle, known as self-dual point. We show that a special type of corner modes exist and they are localized at a very specific type of corners independent of the overall shape of the finite lattice. Moreover, these modes appear even in the perturbed lattice at the corners with mirror planes. By exploring its counterpart in electronic system, we attribute such corner modes to charge accumulation at the boundary, which is confirmed by the plot of charge distribution in a finite lattice.

Bondi accretion in the early universe

Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper presents a study of quasi-steady spherical accretion in the early Universe, before the formation of the first stars and galaxies. The main motivation is to derive the basic formulas that will be used in a companion paper to calculate the accretion luminosity of primordial black holes and their effect on the cosmic ionization history. The following cosmological effects are investigated: the coupling of the gas to the CMB photon fluid (i.e., Compton drag), Hubble expansion, and the growth of the dark matter halo seeded by the gravitational potential of the central point mass. The gas equations of motion are solved assuming either a polytropic or an isothermal equation of state. We consider the cases in which the accreting object is a point mass or a spherical dark matter halo with power-law density profile, as predicted by the theory of "secondary infall''. Analytical solutions for the sonic radius and fitting formulas for the accretion rate are provided. Different accretion regimes exist depending on the mass of the accreting object. If the black hole mass is smaller than 50-100 Msun, gas accretion is unaffected by Compton drag. A point mass and an extended dark halo of equal mass accrete at the same rate if M>5000 Msun, while smaller mass dark halos accrete less efficiently than the equivalent point mass. For masses M>3 x 10^4 Msun, the viscous term due to the Hubble expansion becomes important and the assumption of quasi-steady flow fails. Hence, the steady Bondi solutions transition to the time-dependent self-similar solutions for "cold cosmological infall".

description: In this talk we discuss the microscopic limit of QCD at nonzero chemical potential. In this domain, where the QCD partition function is under complete analytical control, we uncover an entirely new link between the spectral density of the Dirac operator and the chiral condensate: violent complex oscillations on the microscopic scale give rise to the discontinuity of the chiral condensate at zero quark mass. We first establish this relation exactly within a random matrix framework and then analyze the importance of the individual modes by Fourier analysis.

description: Theories of strongly stretched polymer brushes, particularly the parabolic brush theory, are valuable for providing analytically tractable predictions for the thermodynamic behavior of surface-grafted polymers in a wide range of settings. However, the parabolic brush limit fails to describe polymers grafted to convex, curved substrates, such as the surfaces of spherical nanoparticles or the interfaces of strongly segregated block copolymers. It has been previously shown that strongly-stretched, curved brushes require a boundary layer devoid of free chain ends, requiring modifications of the theoretical analysis. While this "end exclusion zone" has been successfully incorporated into descriptions of brushes grafted onto the outer surfaces of cylinders and spheres, the behavior of brushes on surfaces of arbitrary curvature has not yet been studied. We present a formulation of the strong-stretching theory for molten brushes on surfaces of arbitrary curvature and identify four distinct regimes of interest for which brushes are predicted to possess end exclusion zones, notably including regimes of positive mean curvature but negative Gaussian curvature. Through numerical solutions of the strong-stretching brush equations, we report predicted scaling of the size of the end exclusion zone, the chain end distribution, the chain polarization, and the free energy of stretching with mean and Gaussian surface curvatures. Through these results, we present a comprehensive picture of how brush geometry influences the end exclusions zones and exact strong-stretching free energies, which can be applied, for example, to model the full spectrum of brush geometries encountered in block copolymer melt assembly.

description: Spherical symmetry in $f(R)$ gravity is discussed in details considering also the relations with the weak field limit. Exact solutions are obtained for constant Ricci curvature scalar and for Ricci scalar depending on the radial coordinate. In particular, we discuss how to obtain results which can be consistently compared with General Relativity giving the well known post-Newtonian and post-Minkowskian limits. Furthermore, we implement a perturbation approach to obtain solutions up to the first order starting from spherically symmetric backgrounds. Exact solutions are given for several classes of $f(R)$ theories in both $R =$ constant and $R = R(r)$.

description: The latest NA49 results on fluctuations of multiplicity and average transverse-momentum analyzed on an event-by-event basis are presented for central Pb+Pb interactions over the whole SPS energy range (20A - 158A GeV). The scaled variance of the multiplicity distribution decreases with collision energy whereas the $Φ_{p_{T}}$ measure of $$ fluctuations is small and independent of collision energy. Thus in central Pb+Pb collisions these fluctuations do not show an indication of the critical point of strongly interacting matter.

Childhood malnutrition remains a significant global problem, with an estimated 162 million children under the age of five suffering from stunted growth. This article examines the extent to which cash transfer programmes can improve child nutrition. It adopts a framework that captures and explains the pathways and determinants of child nutrition. The framework is then used to organize and discuss relevant evidence from the impact evaluation literature, focusing on impact pathways and new and emerging findings from sub-Saharan Africa to identify critical elements that determine child nutrition outcomes as well as knowledge gaps requiring further research, such as children's dietary diversity, caregiver behaviours and stress.

invisible universes

description: It is quite clear that the discovery of invisible universes is an outstanding and far more significant event than even the discovery of America by Columbus. However, their discovery is hampered not only by the objective difficulties of knowledge nature, but also by the principle of non-exceeding the speed of light of the special theory of relativity (STR), from which the existence of only our visible universe follows. But in the XXI century, experimental knowledge was obtained, from which it followed that the relativistic formulas of the existing version of STR are incorrect and incorrectly explained. In other words, the version of STR created in the 20th century turned out to be not entirely correct. Therefore, an alternative version of S STR RT was created, which made it possible to prove the existence, in addition to our visible universe, of other mutually invisible universes. It is explained how these invisible universes can be seen. But invisible universes are not the only invisible objects that actually exist in nature, which are described by imaginary numbers. Other real-life invisible physical objects correspond to other imaginary numbers. Therefore, the physics of imaginary numbers is the physics of the still largely unknown invisible world. STR

Henotiderus centromaculatus

description: Henotiderus centromaculatus Reitter, 1877 Henotiderus centromaculatus was recorded from Nova Scotia by Bousquet (1991) (as H. obesulus). There are scattered records from the central part of mainland Nova Scotia (Fig. 2). This Nearctic species has been recorded from Alaska and across Canada from the Northwest Territories east to Nova Scotia, and in New Hampshire and New York (Bousquet 1991; Downie and Arnett 1996; Chandler 2001). It is also found in the Eastern Palaearctic in China, Japan, and the Russian Far East (Johnson et al. 2007). Species of Henotiderus are found in leaf litter or associated with polypore fungi such as Polyporus, Pleurotus, and Fomes in forested habitats (Bousquet 1989). All the specimens collected in Nova Scotia were found in red spruce forests, varying in age from young to old growth, except for one specimen collected in a mixed red spruce-eastern hemlock forest (unpublished data).

description: Στην εν λόγω διπλωματική εργασία γίνεται αναφορά στην διαχείριση ανθρώπινου δυναμικού. Στις μέρες μας οι εταιρίες έχουν όλο και μεγαλύτερο αριθμό ανθρώπινου δυναμικού, έχοντας σαν αποτέλεσμα την ανάγκη για ειδική διαχείριση του κάθε ατόμου που ανήκει στο ανθρώπινο δυναμικό ξεχωριστά. Επιπλέον γίνεται αναφορά σε τυχόν συγκρούσεις που δημιουργούνται είτε ανάμεσα στο ανθρώπινο δυναμικό το ίδιο είτε μεταξύ του ανθρώπινου δυναμικού και της ίδια της διοίκησης. Πιο συγκεκριμένα γίνεται αναφορά στα είδη των συγκρούσεων που υπάρχουν. Τους μηχανισμούς αποφυγής και επίλυσής τους. Αναφέρονται τυχόν κανόνες και συμφωνίες που πρέπει να ακολουθηθούν αλλά και κάποια έλλειψη επικοινωνίας που οδηγεί σε πιθανές συγκρούσεις. Γίνεται επίσης αναφορά σε πρακτική εφαρμογή τέτοιων περιπτώσεων με δείγματα τα οποία έχουν ληφθεί μετά από έρευνα σε πολλούς ερωτηθέντες. Στην συνέχεια αναφέρονται στις αντιδράσεις που πρέπει να υπάρχουν σύμφωνα με ερευνητές αλλά και στον τρόπο με τον οποίο πρέπει να λειτουργεί ένας οργανισμός. Τέλος, γίνεται αναφορά στις οργανωτικές αξίες ανθρώπινου δυναμικού και στις προσωπικές θεωρίες προσαρμογής. Επιπλέον αναλύονται οι πρακτικές διαχείρισης πόρων, στην ύπαρξη συστήματος διαχείρισης και στον λόγο ύπαρξής του, όπως επίσης και στον λόγο για τον οποίο τα περισσότερα συστήματα διαχείρισης αποτυγχάνουν.

description: Η παρούσα εργασία εξετάζει τη διαχείριση κρίσεων σε περιπτώσεις φυσικών καταστροφών στην Ευρωπαϊκή Ένωση, με στόχο να αναδείξει τη σημασία και τις στρατηγικές που εφαρμόζονται σε τέτοιες καταστάσεις. Αρχικά, αναλύεται η θεωρητική βάση της διαχείρισης κρίσεων, εστιάζοντας στις αρχές και στους ρόλους που διαδραματίζουν οι εθνικές κυβερνήσεις και η ΕΕ. Στη συνέχεια, η εργασία υιοθετεί μια συνδυαστική προσέγγιση, αναλύοντας περιπτώσεις όπως ο καύσωνας στην Ευρώπη το 2003, η χιονοθύελλα "Xynthia" το 2010, οι πυρκαγιές στην Ελλάδα το 2018, η ηφαιστειακή έκρηξη στο νησί Λα Πάλμα το 2021, ο σεισμός στην Τουρκία και τη Συρία το 2023, καθώς και οι πλημμύρες στην Ελλάδα το 2023. Μέσω της ανάλυσης επίσημων αποφάσεων και στρατηγικών της ΕΕ, καθώς και δημοσιογραφικών άρθρων, η εργασία συγκρίνει τις θεωρητικές προσεγγίσεις με την πραγματικότητα και τις επιπτώσεις τους. Τα ευρήματα επισημαίνουν τις αδυναμίες και τις δυνατότητες βελτίωσης στη διαχείριση κρίσεων, παρέχοντας προτάσεις για την ενίσχυση των διαδικασιών και των μέτρων. Σκοπός είναι η ενίσχυση της ικανότητας των ευρωπαϊκών κρατών να ανταποκριθούν αποτελεσματικά σε φυσικές καταστροφές, βελτιώνοντας έτσι την ασφάλεια και την ευημερία των πολιτών.
description: This paper examines crisis management in cases of natural disasters in the European Union (EU), aiming to highlight the importance and strategies applied in such situations. First, the theoretical basis of crisis management is analysed, focusing on the principles and roles played by national governments and the EU. Then, the paper takes a combined approach, analysing cases such as the heat wave in Europe in 2003, the "Xynthia" snowstorm in 2010, the fires in Greece in 2018, the volcanic eruption on the island of La Palma in 2021, the earthquake in Turkey and Syria in 2023, as well as the floods in Greece in 2023. Through the analysis of official EU decisions and strategies, as well as journalistic articles, the paper compares theoretical approaches with reality and their implications. The findings highlight weaknesses and opportunities for improvement in crisis management, providing suggestions for strengthening processes and measures. The purpose is to strengthen the ability of European states to respond effectively to natural disasters, thus improving the safety and well-being of citizens.

description: Online Syntax (as introduced by Auer 2007, 2009) is an approach to syntax within the framework of Interactional Linguistics. It analyses (turn) constructional units as dialogically emerging in time, taking seriously the claim in Sacks, et al. (1974) that turn constructional units are defined by their projectable termination (pg. 702). The approach is also indebted to Emergent Grammar (Hopper 1998) but assumes that turn projection is based on shared, experience-based grammatical (constructional) knowledge.

description: We report on the observation of terahertz radiation induced photogalvanic currents in semiconductor heterostructures with one-dimensional lateral periodic potential. The potential is produced by etching a grating into the sample surface. The electric current response is well described by phenomenological theory including both the circular and linear photogalvanic effects. Experimental data demonstrate that the inversion asymmetry of the periodic lateral pattern can be varied by means of electron beam lithography to produce classical lateral ratchets. A novel microscopical mechanism for the polarization-dependent photogalvanic effects has been proposed to interpret the experimental findings. The photocurrent generation is based on the combined action of the lateral periodic potential and the modulated in-plane pumping. The latter modulation stems from near-field effects of the radiation propagating through the grating.

description: Contexte : La dépression post-AVC est un problème de santé majeur, et les interventions infirmières peuvent jouer un rôle essentiel dans sa prévention. Toutefois, il est primordial de comprendre dans quelles mesures ces interventions sont efficaces pour accroître le niveau d'auto-efficacité des patients. Objectif : L'objectif de cette revue de littérature est d'explorer les interventions qu'un infirmier peut mettre en place afin d'augmenter l'auto-efficacité et de lutter contre la dépression. Méthodes : Six articles ont été sélectionnés et soumis à une lecture critique. Les concepts clés identifiés étaient l'expérience de maîtrise, l'expérience vicariante, la persuasion verbale, le soutien social, l’état psychologique et émotionnel, le comportement, les facteurs personnels, l’environnement, les performances, l’engagement, la motivation et la résilience, qui sont les principaux aspects sur lesquels les interventions infirmières peuvent se baser. Résultats : Les résultats ont démontré que les interventions visant à accroître l'auto-efficacité avaient un effet bénéfique sur la réduction de l'état dépressif. L'infirmier joue un rôle essentiel dans l'augmentation du sentiment d'auto-efficacité des patients, en intégrant la famille et les proches dans les soins et en développant ses compétences en gestion et en promotion de la santé. Discussion : Bien que la théorie psychologique et sociocognitive de Bandura ne soit pas une théorie infirmière, elle s'est avérée être la plus adaptée pour ce sujet d'étude. Cependant, il y a un besoin de données supplémentaires sur le rôle infirmier dans la prévention de la dépression chez les patients ayant souffert d'un AVC.

description: Standing next to trees as they are consumed by living swirls of heat during a wildfire will make you quickly realize the precarity of your own position. This feeling only deepens after walking past melted microwaves while surveying towns impacted and transformed by this unyielding force. This sense of imbalance between the sites we live in and how we choose to inhabit them is hard to ignore. Yet, away from the fire, the material culture that contributes to this disjunction continues uninterrupted. The objects we use everyday affect the world we live in. This thesis project is about coming to see where we are, how we live, and using objects as storytellers to transfer meaning from this unique place of relations. It is about imagining ways of making that can reknit ways of living. Ways of being tied to the land. I make 3D printed ceramic flasks—vessels made with foraged clays that undergo a transformation, an interaction, as they are vitrified by wildfires. These functional objects are experiments in ways of making that care for the interconnected web of relationships that the objects we put into the world have. Can we co-design collaboratively with natural forces? Can we craft with wildfire? Can we expand our understanding of kinship and use this inclusivity to re-tool our design practices in order to reconsider who, how, and what we are designing for? The hope is that these vessels carry new ways of seeing and an imperative for new ways of acting. This ongoing project is a personal one, consisting of material assemblages that share parts of my relationships with the places I am making in and the more-than-human actors that I am in conversation with—the wind, the clay, the robots, and of course the fire.

description:
Climate change mitigation in developing countries is increasingly expected to generate co-benefits that help meet sustainable development goals. This has been an expectation and a hotly contested issue in REDD+ (reducing emissions from deforestation and forest degradation) since its inception. While the core purpose of REDD+ is to reduce carbon emissions, its legitimacy and success also depend on its impacts on local well-being. To effectively safeguard against negative impacts, we need to know whether and which well-being outcomes can be attributed to REDD+. Yet, distinguishing the effects of choosing particular areas for REDD+ from the effects of the interventions themselves remains a challenge. The Global Comparative Study (GCS) on REDD+ employed a quasi-experimental before-after-control-intervention (BACI) study design to address this challenge and evaluate the impacts of 16 REDD+ pilots across the tropics. We find that the GCS approach allows identification of control groups that represent the counterfactual, thereby permitting attribution of outcomes to REDD+. The GCS experience belies many of the common critiques of the BACI design, especially concerns about collecting baseline data on control groups. Our findings encourage and validate the early planning and up-front investments required to evaluate the local impacts of global climate change mitigation efforts with confidence. The stakes are high, both for the global environment and for local populations directly affected by those efforts. The standards for evidence should be concomitantly high.
