description: We study the electronic and transport properties of a topological insulator nanowire including selective magnetic doping of its surfaces. We use a model which is appropriate to describe materials like Bi$_2$Se$_3$ within a k.p approximation and consider nanowires with a rectangular geometry. Within this model the magnetic doping at the (111) surfaces induces a Zeeman field which opens a gap at the Dirac cones corresponding to the surface states. For obtaining the transport properties in a two terminal configuration we use a recursive Green function method based on a tight-binding model which is obtained by discretizing the original continuous model. For the case of uniform magnetization of two opposite nanowire (111) surfaces we show that the conductance can switch from a quantized value of $e^2/h$ (when the magnetizations are equal) to a very small value (when they are opposite). We also analyze the case of non-uniform magnetizations in which the Zeeman field on the two opposite surfaces change sign at the middle of the wire. For this case we find that conduction by resonant tunneling through a chiral state bound at the middle of the wire is possible. The resonant level position can be tuned by imposing an Aharonov-Bohm flux through the nanowire cross section.

Democratization in the Southern Neighbourhood: Noble Declarations, Unavoidable Dilemmas?
Creators: name: Beerman, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Much of the literature describes the EU's policy towards its southern Neighbouring region, in particular its reluctance to promote democracy more assertively, to be driven by a quest for stability and a preference for the status quo. While this is true to a certain degree, it does not account for the EU's persistent attempts to improve the effectiveness and influence of its democracy promotion policies. Rather, this thesis understands the status quo orientation of EU's Mediterranean policies to be concomitant to the stability-democratization dilemma in a region where opening up the political space is seen to present a crucial challenge to European short-term stability interests. The Union's reluctance to promote democracy more seriously in its southern Neighbourhood is therefore explained in relation to the incompatibility of the EU to reconcile its long-term security strategy with its short-term security interests.

description: It is a fact that Indonesian students have difficulty learning Arabic because of the characteristics and linguistics of different Arabic and Indonesian languages, and their lack of understanding of the similarities between the two languages. The researcher sees that it is necessary to examine the similarities and differences in verbs between the two languages, and then present the way the verb teaches them to give the teacher and learner the desired result. Researchers approached an analytical descriptive approach in the achievement of this study, using comparative analysis methods, to compare between transitive verbs in Arabic and Indonesian and then the researchers divide into two categories, the first category is the equation of transitive verbs in Arabic and Indonesian, the second category is the difference between transitive verbs in Arabic and Indonesian. The study found that the difficulties experienced by Indonesian students began with the following reasons: differences in sentence composition and differences in grammatical and morphological rules.

description: The study explores the development of imagination and science concept formation in toddlers using Conceptual PlayWorld, a model of teaching concepts through imaginary play in early childhood. The study observes toddlers in an early childhood centre in Australia participating in play experiences with educators and other toddlers. The findings demonstrate that the use of props such as toys, costumes, storybooks and pictures encouraged the toddlers to participate in imaginary play and learn various science concepts. The study contributes to the less focused area of research on toddlers' development of imagination and concept formation and informs the early childhood practice and pedagogy.

Retracing the evolution of food planning to imagine a resilient food system
Creators: name: De Marchi, Marta
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: Today the division between city and country is becoming more and more indefinite and it is not possible anymore to consider the rural landscape apart from the urban one. Observing Food System dynamics can be a very useful tool to survey territorial dysfunctions and spatial transformations in their complexity. Food, in fact, is one of the main flows crossing the landscape, according to the urban metabolism theory. From the places of production, to the ones of consumption it involves built spaces and infrastructure; it is ruled by specific policies at different administrative levels, but also influenced by private initiatives and practices; it is a complex system of dynamics that changes the surrounding environment in each phase of the chain. Nevertheless Food system is also very sensitive to external pressure given by climate change and resources supply; in this sense a perspective of resilience could be a strategy to mitigate risks and make a territory or a city more able to adapt to surrounding transformations. In the last fifteen years Food has risen inside the urban planners and designers debate as an autonomous topic, representing one of the main material flows in the urban metabolism theory, but since the beginning of the last century it was considered as an implicit theme inside the planning and urban design discourse, both by professionals and scholars. In the evolution of the European urban design and planning, in fact, we can recognize several experiences in which food had a role in the formulation of new cities visions, during the XX century: the Garden City imagined by Howard and the “New Towns” movement at the beginning of the century; the Italian experience of autocracy between the 20's and the 30's; the Switzerland plan for a national food autonomy between the two wars; the vision for future cities in the Broadacre City project by Frank Lloyd Wright. These experiences rose from very different premises and brought to very different results, both from the theoretical and the practical points of view, but all of them, in different ways, can teach us something in terms of integrating food and productive dynamics inside the urban system. The paper will describe last century experiences from the Food System point of view, to understand how those stories anticipated some ideas related to urban metabolism and some approaches towards a more efficient and resilient territory.

description: We study the thermal conduction behaviors of one-dimensional lattice models with asymmetry harmonic interparticle interactions in this paper. Normal thermal conductivity independent of the system size is observed when the lattice chains are long enough. Because only the harmonic interactions are involved, the result confirms without ambiguous interpretation that the asymmetry plays key role in resulting in the normal thermal conduction in one-dimensional momentum conserving lattices. Both equilibrium and nonequilibrium simulations are performed to support the conclusion.

On ecology and design: about the Brussels school heritage and perspective on urban metabolism

Publisher: name: International Planning History Society Proceedings
Year: 2016

description: The paper aims to highlight the interrelation between ecological studies and urban planning, in particular with regard to the Brussels case, given both its pioneer works and the current revival on urban metabolism. As early as the ‘70s of the last century, in continuity with the organic concept of the XIX century metropolis (the regionalism of Geddes), the ecologist Duvigneaud studied Brussels as an ecosystem. His approach integrated a scientific and socio-natural understanding of urban metabolism. Afterwards, further studies on urban metabolism have flowed into industrial ecology, the study of the material and energy circulation, narrowing the scope of investigation on urban space and nature. More recently, there has been a strong return on the debate of the Brussels urban metabolism. In order to boost the regional economic and social development as well as to meet the urban environmental challenges, new regional programs and plans are asking the urban projects to integrate a strong metabolic perspective. However, it remains to better understand how and to which extent the discipline of urbanism can actually draw from urban metabolism studies, and, in turn, what it can bring to the research field. In answering this question, we look back in particular to the influences and relations between ecological studies and urban design and planning in the recent history of Brussels. On the one hand, the results show that, despite the rising interest in the subject, until now, design and planning practice, in Belgium, seems to have little learnt from urban metabolism studies, showing few significant contributions to the discipline. On the other hand, it clearly emerges that stronger socio-natural perspective is needed in order for urban design and planning to steer the transformation of the city towards a more resilient urban metabolism.

description: We present a method for calculating the energy levels of superconducting circuits that contain highly anharmonic, inductively-shunted modes with arbitrarily strong coupling. Our method starts by calculating the normal modes of the linearized circuit and proceeds with numerical diagonalization in this basis. As an example, we analyze the Hamiltonian of a fluxonium qubit inductively coupled to a readout resonator. While elementary, this simple example is nontrivial because it cannot be efficiently treated by the method known as "black-box quantization," numerical diagonalization in the bare harmonic oscillator basis, or perturbation theory. Calculated spectra are compared to measured spectroscopy data, demonstrating excellent quantitative agreement between theory and experiment.

Van den Broek and Bakema: two types of functionalists. Architecture and Planning Education at Technical College of Delft in Post-war Society

Publisher: name: International Planning History Society Proceedings

description: Europe was damaged badly during the Second World War. Despite the sheer size of the task ahead, the significant destruction, and shortage of manpower and building materials, the Netherlands took up reconstruction expeditiously. With unprecedented resilience battered cities and villages re-emerged from the rubble. The reconstruction was a large-scale operation in which industrially manufactured mass housing and a new cityscape were pursued. During the reconstruction Van den Broek and Bakema Architects were one of the largest offices with influential designs such as the Lijnbaan Shopping Center, the new heart of the bombed city of Rotterdam. Both architects showed great social commitment. Because of the grand scale of construction output in the first decades after the war, J.H. van den Broek and J.B. Bakema asked themselves what the architect’s role and responsibility were in an increasingly technology-dominated society. As both architects were professors at the Technical College of the Dutch university town Delft, it is not surprising that this question was the main theme in their teaching. That goes for their inaugural speeches as well. Addressed in 1948 and 1964 – marking the start and the completion of post-war reconstruction – they show that the architect’s focus had shifted profoundly.

description: ABSTRACT This paper views the City as the product of a complex web of ongoing social and cultural developments. It bases its understanding on the premise that a City and its landscapes, act as agents of historic transmission and documentation that are bound together by the varying degrees of elasticity embodied within them. It proposes that when an engagement with the past happens through the insertion of catalytic programs posited against the historic artifact it creates an episodic urbanism. Collectively viewed these, “episodes” which place the individual at the center of a negotiated urban experience pushes the elastic limits of a city’s resilience and hence acts as both an agent for continuity and change.

description: This paper proposes a new algorithm based on multi-scale stochastic local search with binary representation for training neural networks. In particular, we study the effects of neighborhood evaluation strategies, the effect of the number of bits per weight and that of the maximum weight range used for mapping binary strings to real values. Following this preliminary investigation, we propose a telescopic multi-scale version of local search where the number of bits is increased in an adaptive manner, leading to a faster search and to local minima of better quality. An analysis related to adapting the number of bits in a dynamic way is also presented. The control on the number of bits, which happens in a natural manner in the proposed method, is effective to increase the generalization performance. Benchmark tasks include a highly non-linear artificial problem, a control problem requiring either feed-forward or recurrent architectures for feedback control, and challenging real-world tasks in different application domains. The results demonstrate the effectiveness of the proposed method.

Archaeology and urban sustainability: Can the past provide a key to the future?
Creators: name: Söderström, Ulrika
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: Many of today´s challenges of how to create and plan for sustainable cities in the future holds similarities to those that urban residents and decision makers have been confronted with for centuries. Therefore it is often argued that the past can provide us with knowledge to understand some of these challenges and in this a number of interdisciplinary sciences have an important role to play. However, when it comes to archaeology and especially archaeological knowledge about past urban societies, this role is still explored to a limited extent. The question is: how can archaeological research on prehistoric urban landscapes and cities be useful when planning for and working with urban sustainability today? Can the past provide a key to the future? In a publication from 2014 Christian Isendal (Prof of archaeology at Univ. of Gothenburg) argue that even though urban researchers and planners have extensive knowledge about the history of cities and often refer to the historical dimension, their references in time and space are often limited. It is pointed out that one of the distinct contributions that archaeological urban research can provide is a unique long-term perspective and a broader set of diversified examples to use as a source for creative ideas when discussing urban development and working on finding solutions to urban problems today. In this paper I explore this long-term perspective and discuss how archaeological urban research can be used to point to factors that are central to, and which undermine, sustainable urban development. Drawing upon the conference´s main theme, this paper presents the urban vision of Västergarn, an early medieval settlement on the southwestern coast of Gotland (Sweden), and highlight some of the challenges to its urban development. As many of the cities around the world today, Västergarn showed remarkable resilience as the settlement responded to and recovered from contemporary crises and disasters. Yet its urban growth and development was proven unsustainable and subsequently led to de-urbanization. Through this example I aim to illustrate that archaeological research on prehistoric urban landscapes and cities has considerable potential if it is used for more than just providing a historical perspective on urban development. Rather it can increase our understanding of some of the issues and problems that planning and developing sustainable cities are confronted with now and in the future.

Urbanisation and landscape juxtapositions in Minas Gerais, Brazil: revisiting historical cartographies
Creators: name: Capanema Alvares Fernandes, Patricia
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: The recent discussions following the biggest mining disasters in Minas Gerais bring to the fore the paradoxical relations between economical development versus ecological collateral damages of mining which are central in Minas Gerais, a state that carries mining in is name. The issue is of course embedded in the latent global debate that opposes development and environment. When radical soil transformations - including mining and urbanisation - are extensively performed in the name of development the question of social and ecological resilience becomes crucial. Since the eighteenth century colonial gold rush, urban and territorial development in the region, rich in gold and iron ore, has long been paired with topographical manipulations related to the extraction of these prime resources. These processes have created a landscape of addition and subtraction, where extraction becomes entwined also with the creation of urban fragments. Belo Horizonte, a city created from scratch in the end of the 19th century was no exception. To found the capital of Minas Gerais state, a territory of significant topographical features was soon confronted with the symmetrical array of perpendicular and diagonal streets proposed by the plan of 1895. Over its history, extreme manipulations of ground-surface conditions have not been limited to mining activities but are largely performed to allow urbanisation to take place in the form of heterotopic housing entities. Before the foundational grid had been fully laid out, its first metropolitan extension took place 12 quilometres from ground zero as a elite targeted satellite town around a new lake resulting from the damming of the river Pampulha. The case of Pampulha is exemplary of the critical entwinement between enclaved settlement formation, artificial ground operations, water storage production and social-ecological resilience in Belo Horizonte, offering an inspiring terrain for re-imagining projectively the conflicts between human settlement and ecological cycles. By combining archival material with descriptive and interpretative mappings, this paper will address Pampulha’s emergence and historical development as the spearhead of the entanglement of enclaved urbanism and artificial topographies that is currently a dominant form of urbanisation in Brazil. Aiming to understand the complexity in the processes of transforming earth into land, territory is approached as a palimpsest, combining archival material with descriptive mappings done within the scope of the doctoral research.

description: The estimation of the decay rate of a signal section is an integral component of both blind and non-blind reverberation time estimation methods. Several decay rate estimators have previously been proposed, based on, e.g., linear regression and maximum-likelihood estimation. Unfortunately, most approaches are sensitive to background noise, and/or are fairly demanding in terms of computational complexity. This paper presents a low complexity decay rate estimator, robust to stationary noise, for reverberation time estimation. Simulations using artificial signals, and experiments with speech in ventilation noise, demonstrate the performance and noise robustness of the proposed method.

description: Heat and energy are conceptually different, but often are assumed to be the same without justification. An effective method for investigating diffusion properties in equilibrium systems is discussed. With this method, we demonstrate that for one-dimensional systems, using the indices of particles as the space variable , which has been accepted as a convention, may lead to misleading conclusions. We then show that though in one-dimensional systems there is no general connection between energy diffusion and heat conduction, however, a general connection between heat diffusion and heat conduction may exist. Relaxation behavior of local energy current fluctuations and that of local heat current fluctuations are also studied. We find that they are significantly different, though the global energy current equals the globe heat current.

description: Chinese international students represent one sixth of the international post-secondary student population present in Anglophone Canada. A popular field of study for this demographic is engineering. Considering differences in cultural background and English language barriers, Chinese international students face their own unique set of challenges in university classrooms where collaborative work has become a standard measure to instruct and assess material. Four face-to-face focus groups with fourteen Chinese international students examined how collaborative work with non-Chinese peers shapes the self-perceptions of English language skills by Chinese international students. Using Saldaña’s approach to coding as the selected method, the data generated categories, a concept and a key assertion. Participants’ perceptions of English language are shaped by efficiency, embarrassment and confidence. A desired goal of Chinese international students, which is only achieved by very few, is English language fluency. Suggesting an interrelated relationship, the key assertion proposes that language competence and perceptions develop in four stages. Perceptions and language competence transition through a non-linear process, which ranges from Shock, to the Brutal Upward Learning Curve, Acceptance and eventually Confident Mastery. Focus group participants demonstrated a high level of accurate self-assessment and are forced to adopt a dismissive attitude which allows them to move past negative experiences and perceptions and develop a strong sense of confidence which is necessary for survival.

description: We present a new approach for quantifying the abundance of galaxy clusters and constraining cosmological parameters using dynamical measurements. In the standard method, galaxy line-of-sight (LOS) velocities, $v$, or velocity dispersions are used to infer cluster masses, $M$, in order to quantify the halo mass function (HMF), $dn(M)/d\log(M)$, which is strongly affected by mass measurement errors. In our new method, the probability distribution of velocities for each cluster in the sample are summed to create a new statistic called the velocity distribution function (VDF), $dn(v)/dv$. The VDF can be measured more directly and precisely than the HMF and it can also be robustly predicted with cosmological simulations which capture the dynamics of subhalos or galaxies. We apply these two methods to mock cluster catalogs and forecast the bias and constraints on the matter density parameter $Ω_m$ and the amplitude of matter fluctuations $σ_8$ in flat $Λ$CDM cosmologies. For an example observation of 200 massive clusters, the VDF with (without) velocity errors constrains the parameter combination $σ_8Ω_m^{0.29\ (0.29)} = 0.587 \pm 0.011\ (0.583 \pm 0.011)$ and shows only minor bias. However, the HMF with dynamical mass errors is biased to low $Ω_m$ and high $σ_8$ and the fiducial model lies well outside of the forecast constraints, prior to accounting for Eddington bias. When the VDF is combined with constraints from the cosmic microwave background (CMB), the degeneracy between cosmological parameters can be significantly reduced. Upcoming spectroscopic surveys that probe larger volumes and fainter magnitudes will provide a larger number of clusters for applying the VDF as a cosmological probe.

TIME SERIES PREDICTION OF TCI INDEX USING LSTM AND MAPPING VEHICULAR CARBON MONOXIDE EMISSION FOR NEW DELHI
Creators: name: Gupta, Sawar
Publisher: name: Zenodo
Year: 2023

description: The rapid urbanization and growth in the number of automobiles in India have led to increased congestion on roads and a significant impact on human life and the environment. However, the use of intelligent transportation system data in smart-city programs has opened new opportunities for researchers to utilize this data to optimize traffic monitoring, prediction, and forecasting, and to improve policy formulation by governments and societies. This text discusses various approaches for prediction, including statistical and machine-learning techniques, and the mapping of road-level vehicular emissions. A gap is identified in city-specific studies for New Delhi, where a model is proposed to predict the TCI Index for the city using a deep learning time series prediction algorithm. The index is then used to prepare a road-level Carbon monoxide vehicular emission inventory at hourly flux for over eight weeks of the time period. The study offers a unique method for creating high-resolution traffic emission inventories that can be used in many different cities, especially those that face a scarcity of publicly available data. The results of the simulation are presented in graphical form and show that the predicted values accurately identify the trend of actual values and the Carbon Monoxide emission inventory is successfully generated.

description: Topological superconductors host new states of quantum matter which show a pairing gap in the bulk and gapless surface states providing a platform to realize Majorana fermions. Recently, alkaline-earth metal Sr intercalated Bi2Se3 has been reported to show superconductivity with a Tc ~ 3 K and a large shielding fraction. Here we report systematic normal state electronic structure studies of Sr0.06Bi2Se3 (Tc ~ 2.5 K) by performing photoemission spectroscopy. Using angle-resolved photoemission spectroscopy (ARPES), we observe a quantum well confined two-dimensional (2D) state coexisting with a topological surface state in Sr0.06Bi2Se3. Furthermore, our time-resolved ARPES reveals the relaxation dynamics showing different decay mechanism between the excited topological surface states and the two-dimensional states. Our experimental observation is understood by considering the intra-band scattering for topological surface states and an additional electron phonon scattering for the 2D states, which is responsible for the superconductivity. Our first-principles calculations agree with the more effective scattering and a shorter lifetime of the 2D states. Our results will be helpful in understanding low temperature superconducting states of these topological materials.

description: This is the first in a series of papers presenting methods and results from the Young Solar Analogs Project, which began in 2007. This project monitors both spectroscopically and photometrically a set of 31 young (300 - 1500 Myr) solar-type stars with the goal of gaining insight into the space environment of the Earth during the period when life first appeared. From our spectroscopic observations we derive the Mount Wilson $S$ chromospheric activity index ($S_{\rm MW}$), and describe the method we use to transform our instrumental indices to $S_{\rm MW}$ without the need for a color term. We introduce three photospheric indices based on strong absorption features in the blue-violet spectrum -- the G-band, the Ca I resonance line, and the Hydrogen-$γ$ line -- with the expectation that these indices might prove to be useful in detecting variations in the surface temperatures of active solar-type stars. We also describe our photometric program, and in particular our "Superstar technique" for differential photometry which, instead of relying on a handful of comparison stars, uses the photon flux in the entire star field in the CCD image to derive the program star magnitude. We present time series plots of our spectroscopic data for all four indices, and carry out extensive statistical tests on those time series demonstrating the reality of variations on timescales of years in all four indices. We also statistically test for and discover correlations and anti-correlations between the four indices. We discuss the physical basis of those correlations. As it turns out, the "photospheric" indices appear to be most strongly affected by continuum emission. We thus anticipate that these indices may prove to be useful proxies for monitoring continuum emission in the near ultraviolet.

description: Η ψηφιακή μετάβαση της βιομηχανίας με στόχο την ικανοποίηση της μαζικής παραγωγής είναι ένας από τους βασικούς στόχους της Βιομηχανίας 4.0 (Industry 4.0). Η ανάπτυξη καινοτόμων ψηφιακών τεχνολογιών έχει οδηγήσει σε περισσότερο συνδεδεμένα συστήματα παραγωγής με αποτέλεσμα τη συνεχόμενα αυξανόμενη απόδοση τους. Από την άλλη, η Βιομηχανίας 5.0 (Industry 5.0) στοχεύει στη δημιουργία συστημάτων παραγωγής που θα είναι πιο ανθρωποκεντρικά και ανθεκτικά σε διαταραχές, και θα συμβάλλουν στη βιωσιμότητας του πλανήτη. Ταυτόχρονα, αποσκοπεί στην ανάπτυξη της συνεργασίας των τεχνολογικών λύσεων με τους ανθρώπους για την διευκόλυνση τους στις εργασίες τους και όχι στην αντικατάσταση τους από αυτές. Στην παρούσα εργασία παρουσιάζονται οι στόχοι της Βιομηχανίας 5.0 και τα οφέλη που παρέχει. Γίνεται ανάλυση των βασικών τεχνολογικών καινοτομιών στις οποίες στηρίζεται καθώς και των προκλήσεων για την επιτυχή εφαρμογή τους. Έμφαση δίνεται στις λύσεις που προσφέρει η Βιομηχανία 5.0 τόσο στη διαχείριση εφοδιαστικών αλυσίδων όσο και στη μαζική εξατομικευμένη παραγωγή, μέσα από την παρουσίαση και ανάλυση συγκεκριμένων παραδειγμάτων εφαρμογής.
description: The digital transition of industry towards supporting mass production is one of the main goals of Industry 4.0. The development of enabling digital technologies has led to more connected production systems with ever-increasing efficiency. Industry 5.0, on the other hand, aims to create production systems that are more human-centric and resilient, contributing to the sustainability of the planet. At the same time, it aims to improve the collaboration of technological solutions with the human element to facilitate and not to replace it. This thesis analyses the main the objectives of Industry 5.0 and the benefits it provides. The main technological innovations on which it is based are presented as well as the challenges for their successful implementation. Emphasis is given to the solutions offered by Industry 5.0 both in supply chain management and in mass-customisation, through the presentation and analysis of specific use cases.

description: Avant 2002, l’Outaouais urbain était composé de cinq municipalités autonomes. Or, le gouvernement du Québec a imposé la fusion de plusieurs municipalités faisant partie d’agglomérations urbaines en adoptant le projet de loi 170. En Outaouais, les villes d’Aylmer, Buckingham, Gatineau, Hull et Masson-Angers ont été regroupées pour ne former qu’une seule entité, la Ville de Gatineau. Cette recherche a pour objectif de comprendre comment les identités territoriales des citoyens qui ont vécu ce changement ont pu être influencées par la modification de la structure du territoire sur lequel se déroule une grande partie de leurs interactions sociales au quotidien. Les réponses fournies par 152 participants d’Aylmer et de Masson par l’entremise d’une enquête par questionnaire nous ont permis de dresser un portrait intéressant du point de vue des citoyens qui habitent deux secteurs périphériques de la ville de Gatineau. Somme toute, nous avons pu constater que les citoyens qui ont connu la fusion municipale ne s’identifient pas fortement à la nouvelle ville et qu’ils demeurent ancrés à leur ancienne municipalité.

description: We report on the tentative detection of $trans$ Ethyl Methyl Ether (tEME), $t-CH_3CH_2OCH_3$, through the identification of a large number of rotational lines from each one of the spin states of the molecule towards Orion KL. We also search for $gauche$-$trans$-n-propanol, $Gt-n-CH_3CH_2CH_2OH$, an isomer of tEME in the same source. We have identified lines of both species in the IRAM 30m line survey and in the ALMA Science Verification data. We have obtained ALMA maps to establish the spatial distribution of these species. Whereas tEME mainly arises from the compact ridge component of Orion, Gt-n-propanol appears at the emission peak of ethanol (south hot core). The derived column densities of these species at the location of their emission peaks are $\leq(4.0\pm0.8)\times10^{15} cm^{-2}$ and $\leq(1.0\pm0.2)\times10^{15} cm^{-2}$ for tEME and Gt-n-propanol, respectively. The rotational temperature is $\sim100 K$ for both molecules. We also provide maps of $CH_3OCOH$, $CH_3CH_2OCOH$, $CH_3OCH_3$, $CH_3OH$, and $CH_3CH_2OH$ to compare the distribution of these organic saturated O-bearing species containing methyl and ethyl groups in this region. Abundance ratios of related species and upper limits to the abundances of non-detected ethers are provided. We derive an abundance ratio $N(CH_3OCH_3)/N(tEME)\geq150$ in the compact ridge of Orion.

description: A generalization of the MIT bag boundary condition for spinor matter is proposed basing on the requirement that the Dirac hamiltonian operator be self-adjoint. An influence of a background magnetic field on the vacuum of charged spinor matter confined between two parallel material plates is studied. Employing the most general set of boundary conditions at the plates in the case of the uniform magnetic field directed orthogonally to the plates, we find the pressure from the vacuum onto the plates. In physically plausible situations, the Casimir effect is shown to be repulsive, independently of a choice of boundary conditions and of a distance between the plates.

Better (urban) policies for better lifes. The role of OECD in transnational exchanges of planning ideas in the 1970

description: Transnational History in the field of urban planning largely focused on the first half of the twentieth century (Saunier, Ewen, 2009), although recent works deal with post-war period or after (Planning Perspective, vol. 29, n°2, 2014). The growing role of centralised policies after 1945 explains this, particularly in the case of France or United Kingdom. Nevertheless, it would be abusive to consider that everything came from State administrations. Created in order to advise States, some international organisations reveal, through their works, an another history of transnational exchanges of planning ideas. We offer here to hightlight the work and influence of the OECD on urban planning matters during the 1970s, using the archives of the organisation, located in its headquarter in Paris. At first glance, the institution has nothing to do with planning. In fact, when it was created in 1961, the OECD had no interest on this regard. But in 1969, driven by its new General Secretay, Emile van Lennep, the organisation launched a fundemental environmental turn. Within a new Directorate, a 'Sector Group on the Urban Environment' was created in 1971 whose purpose was to exchange national experiences that could help to improve life in urban areas. Its first assessment was provocatively entitled « exclusion of automobile trafic in downtown areas ». Active throughout the 1970s, the Group worked on many subjects, always using the same method. First, experts had to identify the best local experiences (local level) in order to combine results (transnational level) and finaly make recommandations to States administrations (national level). This way to articulate scales is uncommon for history of exchanges of planning ideas, showing the facilitating role of an international organisation on this regard. This presentation will first contextualise the environmental turn of the organisation that explains its concern about the 'urban environment' and give an overview of the activity of the Sector Group. Then, through the exemple of its first assessment (traffic free areas), it will show the working methods of the group, its contacts at local, national and international levels and the way the organisation dissiminate its conclusions and recommendations. Finally, the presentation will show that, even in such a centralised country as France, the State administration borrowed ideas from OECD's works as a basis for offical acts, suggesting that urban matters had no borders.
