description: The paper analyses the processes of soil degradation which are caused by deforestation and agricultural expantion in Tavushskaya oblast' of Armenia. This includes soil compaction, plant formation loss, intense water and wind erosion on grazelands caused by increase of sheep herd; and soil nutrition losses as a result of drawbacks of land cultivation on hillside cropland. Following the reasons of soil erosion we suggest three scenarios of agricultural and forest land application. The first scenario depicts the current growth rates of deforestation and transforming these areas into cropland, but with time limits of land use because of continuous soil nutrition loss. The second scenario shows the consequences of stopping deforestation and saving current forest area. Finally the third scenario keeps the current forest areas and transforms the degraded grazelands into forestland with a 10% growth rate per decade. Using TEEB methodology for each scenario we calculate the economic value of local ecosystem services, which could be provided from 1 ha in this region for the bext thirty years. The results show that the first scenario gives $ 16 202, the second $32 776 – 1 312 561, and the third $33 904 – 1 359 678 diapason value of potential ecosystem services per 1 hectare. This all means that it is reasonable to save and regenarate forest land, which help to resist soil erosion and thus have positive effect on food security in the region.

description: Selon la nouvelle ingénierie de formation des enseignants au Maroc relative à la loi d’instauration des Centres Régionaux de l’Education et de la Formation (CRMEF), les enseignants forment et encadrent les futurs professeurs tout au long de leur formation. Cette dernière, basée sur l’approche par compétence, implique une meilleure cohérence des modules et assure la professionnalisation des pratiques enseignantes. Le présent travail se propose d’étudier l’importance de l’encadrement des futurs enseignants des Sciences de la Vie et de la Terre (SVT) dans l’amélioration des pratiques enseignantes de ces derniers. A cet effet, nous avons effectué depuis l’année de formation 2011-2012, au sein de la section SVT du CRMEF de Meknès un suivi rigoureux des professeurs stagiaires. Nous avons réalisé cette étude à l’aide d’une grille d’évaluation en amont et en aval de la formation.
Les résultats obtenus ont montré l’existence de trois catégories d’enseignants selon deux paramètres : la 1ère ne possédait ni connaissances théoriques dans les sciences de l’apprentissage ni expérience pratique, la 2ème avait des connaissances théoriques insuffisantes mais une expérience pratique importante et la dernière avait un savoir théorique majeur mais une expérience pratique insuffisante. Cependant, l’encadrement et le suivi que nous avons assurés à ces enseignants tout au long de leur formation au sein du CRMEF ont amélioré leurs pratiques enseignantes.

description: Time-periodic driving in the form of coherent radiation provides powerful tool for the manipulation of topological materials or synthetic quantum matter. In this paper we propose a scheme to realize non-Hermitian semimetals exhibiting exceptional rings in the spectra through Floquet engineering. A transition from a concentric pair of the rings to a dipolar pair is observed. The concentric pair carries only a quantized Berry phase while the dipolar pair possesses opposite Chern numbers in addition, signaling a topological Lifshitz transition of the Fermi surface. The transport properties of the system are addressed, and we find that this transition process is accompanied by the emergency of a nontrivial Hall conductivity. Furthermore, we explore the quantum simulation of non-Hermitian semimetals with a quantum spin system and the characterization of the topology via the long-time dynamics.

description: The article presents a cognitive model of competence in the form of an oriented weighted graph, identifies systemic characteristics of competence, and uses information entropy to determine the degree of significance of the studied disciplines. Based on the cognitive model, a procedure for assessing the level of competence has been developed using an integral criterion, which takes into account the degree of assimilation of disciplines at a given point in time and the degree of their influence on the formation of competence. It also introduces the concept of the life cycle of competence, which consists of three stages, for each of which an algorithm has been developed tracking the degree of competency development A set of suggestions is put forth to restructure the current system of planning and overseeing the execution of the primary educational program, as well as to increase the functionality of software modules utilized in automated university management systems, based on the scoring evaluations of the university rating system.

description: Les eaux résiduaires urbaines de la ville de Meknès constituent un réceptacle des effluents provenant des activités diverses, entre autres industrielles, hospitalières, agricoles … etc ; et ceci sans aucun traitement préalable. L’hôpital Mohammed V est l’un des plus importants établissements de santé publique à avoir des impacts sur ces eaux ; ses effluents sont déversés directement sans aucun traitement préalable dans le réseau d’assainissement de la ville et dégagés à ciel ouvert au niveau du quartier Ain Choubbik. C’est un hôpital très important à l’échelle régionale aussi bien que nationale ; il appartient à la classe 7 selon la classification de l’American Hospital Association [1] reposant sur le nombre de lits actifs, sa capacité litière est de l’ordre de 531 lits dont 416 sont fonctionnels ; d’où l’importance de le choisir comme modèle dans cette étude. L’objectif de cette recherche est de caractériser la pollution bactériologique des effluents de cet hôpital, estimer son intensité en la comparant avec celle d’autres effluents hospitaliers étudiés antérieurement, et puis avec celle des effluents urbains d’Ain Choubbik en vue d’estimer ses impacts sur ceux-ci. En effet les paramètres bactériologiques mesurés et comparés en deux stations : le regard principal des effluents de l’hôpital Mohamed V de Meknès et les eaux usées urbaines de Aïn Choubbik montrent que le taux de certaines espèces bactériennes dans celles-ci est très élevé par rapport aux effluents hospitaliers, il s’agit des coliformes totaux, coliformes fécaux et streptocoques fécaux ; pour d’autres espèces telles que les spores du clostridium, les germes totaux et les staphylocoques, leur concentration dans l’effluent de l’hôpital Mohamed V de Meknès est plutôt plus élevée par rapport à celle de l’effluent urbain de Aïn Choubbik.

description: It is well known that a Shannon based definition of information entropy leads in the classical case to the Boltzmann entropy. It is tempting to regard the Von Neumann entropy as the corresponding quantum mechanical definition. But the latter is problematic from quantum information point of view. Consequently we introduce a new definition of entropy that reflects the inherent uncertainty of quantum mechanical states. We derive for it an explicit expression, and discuss some of its general properties. We distinguish between the minimum uncertainty entropy of pure states, and the excess statistical entropy of mixtures.

description: RÉSUMÉ: La présente étude s’inscrit dans le cadre des travaux de recherche qui ont pour objectif d’évaluer l’état actuel de l’enseignement préscolaire au Maroc en général et à Meknès en particulier. Elle a été réalisée à l’aide des entretiens face à face avec les divers responsables au sein de l’académie régionale de l’éducation et de la formation Meknès-Tafilalet ainsi qu’à la direction provinciale de Meknès. Cela nous a permis l’investigation des documents officiels et l’analyse de l’état d’enseignement préscolaire et des curricula. Un questionnaire a également été administré à un échantillon représentatif d’éducateurs du préscolaire au niveau de 67 établissements. La recherche a révélé que l’offre préscolaire au Maroc demeure toujours restreinte et insatisfaisante sur le plan qualité aussi bien que quantité, et ce malgré l’adoption du programme d’urgence (2009-2012) qui a ambitionné de généraliser de nouveau un enseignement préscolaire de qualité. La quasi-totalitédes établissements préscolaires sont privés (Kouttab et établissements modernes) et inégalement répartis sur l’ensemble des communes. Nombreux d’entre eux ne répondent pas au cahier de charge élaboré par les autorités éducatives compétentes.Une trop grande diversité des curricula doublée d’une absence de formation des éducateurs ne font que nuire à la qualité de ce type d’enseignement. Tous ces points correspondent à des obstacles et défis que doit surmonter le gouvernement marocain afin de développer et améliorer l’éducation préscolaire dans le territoire marocain.

description: We estimate the temperature dependence of the bulk viscosity in a relativistic hadron gas. Employing the Green-Kubo formalism in the SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) transport approach, we study different hadronic systems in increasing order of complexity. We analyze the (in)validity of the single exponential relaxation ansatz for the bulk-channel correlation function and the strong influence of the resonances and their lifetimes. We discuss the difference between the inclusive bulk viscosity of an equilibrated, long-lived system, and the effective bulk viscosity of a short-lived mixture like the hadronic phase of relativistic heavy-ion collisions, where the processes whose inverse relaxation rate are larger than the fireball duration are excluded from the analysis. This clarifies the differences between previous approaches which computed the bulk viscosity including/excluding the very slow processes in the hadron gas. We compare our final results with previous hadron gas calculations and confirm a decreasing trend of the inclusive bulk viscosity over entropy density as temperature increases, whereas the effective bulk viscosity to entropy ratio, while being lower than the inclusive one, shows no strong dependence to temperature.

description: Two-fluxon state in an annular Josephson junction in the presence of external magnetic field is studied analytically, numerically and experimentally. We obtain an analytical expression for the potential of interaction between the fluxons moving at arbitrary velocities (without the use of the "nonrelativistic" approximation). Treating the fluxons as quasi-particles, we then derive equations of motion for them. Direct simulations of the full extended sine-Gordon equation are in good agreement with results produced by the analytical model, in a relevant parameter region. Experimental data qualitatively agree with the numerical results.

description: The efficient utilization of available resources while simultaneously achieving control objectives is a primary motivation in the event-triggered control paradigm. In many modern control applications, one such objective is enforcing the safety of a system. The goal of this paper is to carry out this vision by combining event-triggered and safety-critical control design. We discuss how a direct transcription, in the context of safety, of event-triggered methods for stabilization may result in designs that are not implementable on real hardware due to the lack of a minimum interevent time. We provide a counterexample showing this phenomena and, building on the insight gained, propose an event-triggered control approach via Input to State Safe Barrier Functions that achieves safety while ensuring that interevent times are uniformly lower bounded. We illustrate our results in simulation.

description: The scanning-tunneling-microscope-induced luminescence emerges recently as an incisive tool to measure the molecular properties down to the single-molecule level. The rapid experimental progress is far ahead of the theoretical effort to understand the observed phenomena. Such incompetence leads to a significant difficulty in quantitatively assigning the observed feature of the fluorescence spectrum to the structure and dynamics of a single molecule. This letter is devoted to reveal the microscopic origin of the molecular excitation via inelastic scattering of the tunneling electrons in scanning tunneling microscope. The current theory explains the observed large photon counting asymmetry between the molecular luminescence intensity at positive and negative bias voltage.
A roadmap for bootstrapping critical gauge theories: decoupling operators of conformal field theories in $d>2$ dimensions

description: We propose a roadmap for bootstrapping conformal field theories (CFTs) described by gauge theories in dimensions $d>2$. In particular, we provide a simple and workable answer to the question of how to detect the gauge group in the bootstrap calculation. Our recipe is based on the notion of \emph{decoupling operator}, which has a simple (gauge) group theoretical origin, and is reminiscent of the null operator of $2d$ Wess-Zumino-Witten CFTs in higher dimensions. Using the decoupling operator we can efficiently detect the rank (i.e. color number) of gauge groups, e.g., by imposing gap conditions in the CFT spectrum. We also discuss the physics of the equation of motion, which has interesting consequences in the CFT spectrum as well. As an application of our recipes, we study a prototypical critical gauge theory, namely the scalar QED which has a $U(1)$ gauge field interacting with critical bosons. We show that the scalar QED can be solved by conformal bootstrap, namely we have obtained its kinks and islands in both $d=3$ and $d=2+\epsilon$ dimensions.
Classical and Quantum Decay of Oscillatons: Oscillating Self-Gravitating Real Scalar Field Solitons

description: The oscillating gravitational field of an oscillaton of finite mass M causes it to lose energy by emitting classical scalar field waves, but at a rate that is non-perturbatively tiny for small GMm, where m is the scalar field mass: d(GM)/dt ~ -3797437.776333015 e^[-39.433795197160163/(GMm)]/(GMm)^2. Oscillatons also decay by the quantum process of the annihilation of scalarons into gravitons, which is only perturbatively small in GMm, giving by itself d(GM)/dt ~ - 0.008513223934732692 G m^2 (GMm)^5. Thus the quantum decay is faster than the classical one for Gmm < 39.4338/[ln(1/Gm^2)}-7ln(GMm)+19.9160]. The time for an oscillaton to decay away completely into free scalarons and gravitons is ~ 2/(G^5 m^11) ~ 10^324 yr (1 meV/m)^11. Oscillatons of more than one real scalar field of the same mass generically asymptotically approach a static-geometry U(1) boson star configuration with GMm = GM_0 m, at the rate d(GM/c^3)/dt ~ [(C/(GMm)^4)e^{-alpha/(GMm)}+Q(m/m_{Pl})^2(GMm)^3] [(GMm)^2-(GM_0 m)^2], with GM_0 m depending on the magnitudes and relative phases of the oscillating fields, and with the same constants C, alpha, and Q given numerically above for the single-field case that is equivalent to GM_0 m = 0.

description: We are concerned with the structural stability of conical shocks in the three-dimensional steady supersonic flows past Lipschitz perturbed cones whose vertex angles are less than the critical angle. The flows under consideration are governed by the steady isothermal Euler equations for potential flow with axisymmetry so that the equations contain a singular geometric source term. We first formulate the shock stability problem as an initial-boundary value problem with the leading conical shock-front as a free boundary, and then establish the existence and asymptotic behavior of global entropy solutions of bounded variation (BV) of the problem. To achieve this, we first develop a modified Glimm scheme to construct approximate solutions via self-similar solutions as building blocks in order to incorporate with the geometric source term. Then we introduce the Glimm-type functional, based on the local interaction estimates between weak waves, the strong leading conical shock, and self-similar solutions, as well as the estimates of the center changes of the self-similar solutions. To make sure the decreasing of the Glimm-type functional, we choose appropriate weights by careful asymptotic analysis of the reflection coefficients in the interaction estimates, when the Mach number of the incoming flow is sufficiently large. Finally, we establish the existence of global entropy solutions involving a strong leading conical shock-front, besides weak waves, under the conditions that the Mach number of the incoming flow is sufficiently large and the weighted total variation of the slopes of the generating curve of the Lipschitz perturbed cone is sufficiently small. Furthermore, the entropy solution is shown to approach asymptotically the self-similar solution that is determined by the incoming flow and the asymptotic tangent of the cone boundary at infinity.

description: The analysis of nonlinear wave equations has experienced a dramatic growth in the last ten years or so. The key factor in this has been the transition from linear analysis, first to the study of bilinear and multilinear wave interactions, useful in the analysis of semilinear equations, and next to the study of nonlinear wave interactions, arising in fully nonlinear equations. The dispersion phenomena plays a crucial role in these problems. The purpose of this article is to highlight a few recent ideas and results, as well as to present some open problems and possible future directions in this field.

description: We investigate the nature of the point-like optical ``cores'' that have been found in the centres of the host galaxies of a majority of radio galaxies by the Hubble Space Telescope. We examine the evidence that these optical cores are relativistically beamed, and look for differences in the behaviour of the cores found in radio galaxies of the two Fanaroff-Riley types. We also attempt to relate this behaviour to the properties of the optical nuclei in their highly beamed counterparts (the BL Lac objects and radio-loud quasars) as hypothesized by the simple Unified Scheme. Simple model-fitting of the data suggests that the emission may be coming from a non-thermal relativistic jet. It is also suggestive that the contribution from an accretion disk is not significant for the FRI objects and for the narrow-line radio galaxies of FRII type, while it may be significant for the Broad-line objects, and consistent with the idea that the FRII optical cores seem to suffer from extinction due to an obscuring torus while the FRI optical cores do not. These results are in agreement with the Unified Scheme for radio-loud AGNs.

title: Understanding Consumer Behaviour Regarding the Sustainable Consumption of Clothing
Creators: name: Crommentuijn-Marsh, Philippa Jane
Publisher: name: The Open University
Year: 2018

description: In response to the rapidly growing consumption of clothing, environmental sustainability concerns have increasingly been expressed. While designers and industry have worked on responses, little is known about how ordinary consumers understand sustainability with regarding to clothing. A study by Defra in 2008 revealed a low awareness of sustainability and proposed sustainable fashion goals for consumers. Research on consumer clothing purchase tends to be from a marketing perspective with the ultimate aim of increasing consumer sales. Much of the literature on clothing sustainability has focused on the buying of ethical/environmentally-friendly clothing and on younger consumers. By contrast, this thesis has focused on an in-depth study of ten mothers aged between 25 and 60 in and around Leicester. The women’s clothing consumption was investigated through shopping trips, wardrobe sampling and a semi-structured interview about their shopping and ownership behaviour. Only at the end of the data gathering were the participants asked about sustainability in general before exploring their understanding of sustainability in clothing. The research revealed that while the participants were concerned about environmental issues, their awareness of sustainability in clothing was low, even though their clothes buying and use behaviour was relatively sustainable. They bought a limited number of garments and wore them for many years, bought second hand clothes and passed their own unwanted clothes to charity shops. However, their clothes buying and use behaviours were shaped by their life circumstances and their personality. The participants had a strong sense of their own personal styles and selected clothes they know would suit them from a limited number of brands and locations. They showed little interest in fast changing fashion trends, but they were influenced by their peer group. Any environmentally-beneficial behaviours were mainly a by-product of these core determining factors. A key contribution of this research is to show how more sustainable behaviour emerges when there is a good match to factors already embedded in people’s daily consumption practices. Building on these core factors, and on how knowledge develops around them, might be an important part of promoting clothing sustainability.
Ornithology of desire : birding in the ecotone and the poetry of Don McKay
Creators: name: Mason, Travis Vincent
Publisher: name: University of British Columbia
Year: 2011

description: In this dissertation I develop a vocabulary and a strategy for reading birds and ecology in Don McKay's poetry. Stressing the importance of understanding such sciences as ornithology and ecology when adopting an interdisciplinary ecocriticism, I posit science textbooks, field guides, and extra-textual experience as valid intertextual referents. At base, my dissertation follows McKay's taxonomical and ecological specificity and argues that such accurate knowing, combined with an awareness of its epistemological limitations, invites readers to reconsider human-nonhuman relations. Individual birds populating McKay's poems exist both as birds that live independently of human language and as symbols of a human desire to name and know the world without possessing it. I begin by highlighting the need for sustained critical work on Don McKay, a poet whose work--long admired by awards juries and fellow poets--has only recently begun to receive the attention it deserves. After outlining the risks involved for literary critics who linger in the ecotone between disciplines, I make an argument for taking seriously the "eco" in ecocriticism by linking the philosophical concerns of the historic science-and-literature debate to the methodological concerns of contemporary ecocriticism. Focusing on two biological aspects of avian ecology--flight and song--I then examine how they function in the English literary canon and how McKay resists the canon by redeploying certain conventions by inflecting them with his "poetic attention" and species specificity. Reading flight in McKay's poems, I demonstrate how McKay provides a strategy for recognizing a human desire to fly as an anti-ecological version of the will to power; reading birdsong, I develop a way of measuring phenomenological distances between poet and bird, language and world. Between chapters, I include what I am calling Ecotones, fictional accounts of a literary critic struggling to enact the interdisciplinary ecocriticism outlined in this dissertation. Each Ecotone--Field Marks, Field Guides, Field Notes--focuses on different versions of "field," highlighting the intellectual risks and benefits associated with occupying a space between. Finally, since McKay is a living writer at the most prolific phase of his career, I conclude by suggesting how future studies of McKay's work, including on what he calls "geopoetry," might productively benefit from the strategies I develop here.

description: Experimental data indicate that the mass tensor of collective Bohr Hamiltonian cannot be considered as a constant but should be considered as a function of the collective coordinates. In this work our purpose is to investigate the properties of low-lying collective states of the odd nuclei $^{173}$Yb and $^{163}$Dy by using a new generalized version of the collective quadrupole Bohr Hamiltonian with deformation-dependent mass coefficients. The proposed new version of the Bohr Hamiltonian is solved for Davidson potential in $β$ shape variable, while the $γ$ potential is taken to be equal to the harmonic oscillator. The obtained results of the excitation energies and B(E2) reduced transition probabilities show an overall agreement with the experimental data. Moreover, we investigate the effect of the deformation dependent mass parameter on energy spectra and transition rates in both cases, namely: when the mass coefficients are different and when they are equal. Besides, we will show the positive effect of the present formalism on the moment of inertia.

Small Black Holes on Branes: Is the horizon regular or singular ?

description: We investigate the following question: Consider a small mass, with $ε$ (the ratio of the Schwarzschild radius and the bulk curvature length) much smaller than 1, that is confined to the TeV brane in the Randall-Sundrum I scenario. Does it form a black hole with a regular horizon, or a naked singularity? The metric is expanded in $ε$ and the asymptotic form of the metric is given by the weak field approximation (linear in the mass). In first order of $ε$ we show that the iteration of the weak field solution, which includes only integer powers of the mass, leads to a solution that has a singular horizon. We find a solution with a regular horizon but its asymptotic expansion in the mass also contains half integer powers.

description: Secret sharing provides a means to distribute shares of a secret such that any authorized subset of shares, specified by an access structure, can be pooled together to recompute the secret. The standard secret sharing model requires public access structures, which violates privacy and facilitates the adversary by revealing high-value targets. In this paper, we address this shortcoming by introducing \emph{hidden access structures}, which remain secret until some authorized subset of parties collaborate. The central piece of this work is the construction of a set-system $\mathcal{H}$ with strictly greater than $\exp\left(c \dfrac{1.5 (\log h)^2}{\log \log h}\right)$ subsets of a set of $h$ elements. Our set-system $\mathcal{H}$ is defined over $\mathbb{Z}_m$, where $m$ is a non-prime-power, such that the size of each set in $\mathcal{H}$ is divisible by $m$ but the sizes of their pairwise intersections are not divisible by $m$, unless one set is a subset of another. We derive a vector family $\mathcal{V}$ from $\mathcal{H}$ such that superset-subset relationships in $\mathcal{H}$ are represented by inner products in $\mathcal{V}$. We use $\mathcal{V}$ to "encode" the access structures and thereby develop the first \emph{access structure hiding} secret sharing scheme. For a setting with $\ell$ parties, our scheme supports $2^{\binom{\ell}{\ell/2+1}}$ out of the $2^{2^{\ell - O(\log \ell)}}$ total monotone access structures, and its maximum share size for any access structures is $(1+ o(1)) \dfrac{2^{\ell+1}}{\sqrt{π\ell/2}}$. The scheme assumes semi-honest polynomial-time parties, and its security relies on the Generalized Diffie-Hellman assumption.

description: The concept and component stocks according to national accounting standards are revealed. The procedure for forming the initial value of the stock, depending on the way they arrive at the company according to the guidelines as well as methods for evaluating stocks of own production is grounded. The methodological principles of formation of information on stocks and the disclosure of its financial statements are considered. In the article investigated the procedure of forming the original value of stocks depending on how they flow to the enterprise. Number of methods of assessment of inventory, which can be used to reflect their value in the accounting and financial reporting, and methods of evaluation of own production is characterized. Identified costs are included in the initial cost of inventories, including inventories of own production. The estimation of the definition of agricultural produce at fair value and features of its application in the enterprise is proposed by authors.

description: A number of Swampland conjectures and in particular the Trans-Planckian Censorship Conjecture (TCC) suggest that de Sitter space is highly unstable if it exists at all. In this paper we construct effective theories of scalars rolling on potentials which are dual to a chain of short-lived dS spaces decaying from one to the next through a cascade of non-perturbative nucleation of bubbles. We find constraints on the effective potential resulting from various swampland criteria, including TCC, Weak Gravity Conjecture and Distance Conjecture. Surprisingly we find that TCC essentially incorporates all the other ones, and leads to a subclass of possible dual effective potentials. These results marginally rule out emergence of eternal inflation in the dual effective theory. We discuss some cosmological implications of our observations.
