Les dessous de la ville créative : Saint-Etienne, entre modèles théoriques et pratique
Authors: Sechi Giovanni 
Published: July 2016

Pourquoi les gouvernements locaux choisissent-ils la culture et la créativité pour développer leurs villes ? Comment traduisent-ils empiriquement les modèles du développement par l’économie culturelle en politiques et projets ? La convergence des politiques de renouvellement urbain par la culture et la créativité s’inspire de « bonnes pratiques » : construction de bâtiments emblématiques, attraction de la classe créative, création de quartiers créatifs, etc. Ces opérations renvoient à différentes approches théoriques qui répondent à des principes et logiques différentes : le modèle de la classe créative, le modèle conventionnel, le modèle du cluster culturel, etc. L’étude du cas de Saint-Étienne nous montre que les villes ont tendance à adopter et articuler des modèles de développement par l’économie culturelle, réunis sous la notion de ville créative, pour des objectifs de développement conventionnels.

Mladoneolitičtí zemědělci a kruhové monumenty. Trojitý rondel kultury s vypíchanou keramikou v Plotištích n/L II
Authors: Kovárník Jaromír 
Published: July 2016

Článek pojednává o kruhových ohrazeních tvořených příkopy a valy, tzv. rondelech. Šlo o monumentální areály pravděpodobně sloužící k shromažďování zemědělců mladšího neolitu z kultovních, společenských, organizačních aj. důvodů. Následuje shrnutí výsledků archeologického výzkumu trojitého rondelu kultury s vypíchanou keramikou (dále SBK), subfáze SBK IVa u Plotišť n/L z první sezóny. Uskutečňuje jej katedra archeologie Filozofické fakulty Univerzity Hradec Králové. Zkoumali jsme plochu severozápadního vstupu v prostoru ukončení jihozápadního a severozápadního segmentu vnitřního příkopu. Zjistili jsme, že vnitřní příkop dosahoval šířku 510–522 cm a hloubku 240 cm. Příkopy vymezující vstup jsou široké 335 cm a hluboké 178 cm. Příkopy mají širší hrotitý tvar a zasahují do stěrkopísčitého podloží. Menší příkopy probíhající po obou stranách severozápadního vstupu se nespojily s vnitřním příkopem. Velký význam má vrstva č. 2 výplně příkopů tvořená zeminou s příměsí menších křemenných valounů (původem z terasy Labe) a nacházející se pod hořejší vrstvou černozemě č. 1. Nabízí se jedna z možností, že by k jejímu vzniku mohlo dojít postupnou erozí tělesa valu na vnější straně příkopů. Soubor nálezů tvoří zlomky hrnců a mís zdobených středně velkým a velkým dvojvpichem, pruhy jemného a středně velkého trojvpichu a výjimečně „taženým“ širokým vpichem zanechávajícím na povrchu keramiky mírně zahloubený pás. Tvary nádob i výzdoba jsou příznačné pro fázi SBK IVa. Některé by mohly být i mladší (subfáze SBK IVa2–IVb).
O roli stravy v životě reemigranta. Vliv stravovacích návyků na formování identity československých přesídlenců z Bulharska
Authors: Džulajová Olga 
Published: July 2016

Text, který držíte v rukou, staví do ohniska svého zájmu stravu a stravování nejen jako ryze biologický akt, jenž je vnímán ´pouze´ jako prostředek k uspokojení základní existenční potřeby člověka, a jako takový je objektivní a unifikovaný pro všechny zástupce lidského druhu, ale poukazuje i na subjektivní, sociálně konstruované vlastnosti stravy a praktiky s ní spojené, jež zaujímají nezanedbatelnou úlohu v každodenním životě lidí. Vycházím zde z myšlenky, že fráze ´Jsme to, co jíme´ není jen prázdná konstrukce, ale sdělení, které v sobě kóduje zprávu – zprávu o tom, že jídlo je kultura na úrovni produkce i konzumace, jelikož je spojeno nejen s faktory ekonomickými či nutričními, ale i se symbolickými hodnotami, které k dané stravě přísluší. Prezentovaný článek se zaměřuje na problematiku stravy ze sociálně-konstruktivistické perspektivy a objasňuje, jakým způsobem a do jaké míry může představovat kultura, odehrávající se na poli stravovacích praktik, prostředek vytyčující hranice mezi ´vlastní´ a ´cizí´ skupinou, posilovat vazby uvnitř jednotky i vědomí vlastní sounáležitosti s ní a vytvářet tak platformu pro etablování specifické skupinové identity.

Žijeme v „době plastové“. Obrovské množství plastů vstupuje do životního prostředí a z tohoto materiálu se uvolňuje řada chemikálií s endokrinně disrupčními účinky. Bisfenol A (BPA) je znám jako jeden z takových účinných endokrinních disruptorů uvolňovaných z plastů. Tato látka vykazuje široké spektrum negativních efektů na zdraví zvířat i lidí. Proto bylo používání BPA v řadě lidských oborů omezeno a u mnoha výrobků je garantováno, že BPA neobsahují. BPA může v plastech chybět, jen pokud je nahrazen jinými látkami. Jako náhrada za BPA se často používá bisfenol S (BPS), i když jeho endokrinně disrupční účinky jsou prozkoumány jen velmi málo. Jako chemikálie, jejíž používání podléhá mnohem slabší legislativní regulaci než její předchůdce, je nyní BPS používán v mnoha materiálech. Nově získávané poznatky ale stále jasněji ukazují, že BPS není zdaleka bezpečná látka. Nenápadná náhrada BPA za BPS může být vnímána jako zlepšení. Ale zdá se, že tomu přesně naopak. S tím, jak se BPS šíří naším „do plastu zabaleným“ světem, jsme se jen dostali z bláta do louže.

Authors: Costa Emanuel Arnoni , Finger César Augusto Guimarães , Schneider Paulo Renato , Hess André Felipe 
Published: July 2016

Funções de afilamento permitem determinar classes de dimensão e volumes das árvores com aplicação direta no planejamento das atividades técnicas e econômicas da floresta. Com esse propósito, os objetivos do presente estudo foram descrever o afilamento do fuste de Araucaria angustifolia (Bertol.) Kuntze na porção compreendida entre o nível do solo e a inserção da copa de árvores de remanescente florestal nativo, bem como ajustar modelo de regressão para a relação altura/DAP, para o diâmetro na inserção da copa sobre o DAP e demonstrar a aplicação das funções com a confecção de uma tabela de sortimentos de madeira. Oitenta e cinco árvores tiveram medidas seus diâmetros e alturas relativas pelo método de cubagem rigorosa de Hohenadl, assim como o diâmetro na inserção da copa com o Criterion RD 1000. Os modelos de afilamento ajustados por regressão foram o polinômio do 5º grau, Kozak (1988), Lee et al. (2003) e Sharma e Zhang (2004). O coeficiente de determinação ajustado (R²aj), o erro padrão da estimativa em porcentagem (Syx%) e a análise gráfica entre valores estimados e observados foram as estatísticas usadas para avaliar o ajuste e a precisão dos modelos. O modelo da relação altura/DAP e do diâmetro no ponto de inserção da copa alcançaram boas estatísticas de ajuste e precisão, permitindo sua aplicação em inventários florestais e no planejamento da produção florestal. A flexibilidade e a eficiência do modelo de Kozak (1988) em predizer diâmetros e volumes até o ponto de inserção da copa favorecem o uso e obtenção de sortimentos de madeira de araucária.
SIMULAÇÃO NUMÉRICA DE DOIS SISTEMAS CONVECTIVOS DE MESOESCALA UTILIZANDO O MODELO WRF
Authors: Casarin Kauan Vargas 
Published: July 2016

The model Weather Research and Forecasting (WRF) was used in order to simulate two Mesoscale Convective Systems (MCSs) with different characteristics in order to analyze how variables such as wind directional shear and thickness gradient are modified within the MCSs along its entire duration. The first event is a linear MCS that extended from the north of Argentina to the South Atlantic in November 30, 2009 and the second is a circular MCS or MCC (mesoscale convective complex) that occurred on the RS and Uruguay on November 18, 2009. The two systems were identified through images of the satellite GOES (Geostationary Operational Environmental Satellite) using an automatic tracking of MCSs and for the simulation of events in WRF we used the data reanalysis of CFSR (Climate Forecast System Reanalysis). The simulation results indicated that the rate of reduction thickness gradient is greater in the circular case than in the linear case and at the time that events are initiated the wind directional shear is higher in the linear case but he reduces until the moment of dissipation of the MCS different than occurs in MCC, which has an increased wind directional shear when the system is almost dissipating.
Climate, soil organic layer, and nitrogen jointly drive forest development after fire in the North American boreal zone

Published: July 2016

AbstractPrevious empirical work has shown that feedbacks between fire severity, soil organic layer thickness, tree recruitment, and forest growth are important factors controlling carbon accumulation after fire disturbance. However, current boreal forest models inadequately simulate this feedback. We address this deficiency by updating the ED2 model to include a dynamic feedback between soil organic layer thickness, tree recruitment, and forest growth. The model is validated against observations spanning monthly to centennial time scales and ranging from Alaska to Quebec. We then quantify differences in forest development after fire disturbance resulting from changes in soil organic layer accumulation, temperature, nitrogen availability, and atmospheric CO2. First, we find that ED2 accurately reproduces observations when a dynamic soil organic layer is included. Second, simulations indicate that the presence of a thick soil organic layer after a mild fire disturbance decreases decomposition and productivity. The combination of the biological and physical effects increases or decreases total ecosystem carbon depending on local conditions. Third, with a 4°C temperature increase, some forests transition from undergoing succession to needleleaf forests to recruiting multiple cohorts of broadleaf trees, decreasing total ecosystem carbon by ∼40% after 300 years. However, the presence of a thick soil organic layer due to a persistently mild fire regime can prevent this transition and mediate carbon losses even under warmer temperatures. Fourth, nitrogen availability regulates successional dynamics; broadleaf species are less competitive with needleleaf trees under low nitrogen regimes. Fifth, the boreal forest shows additional short‐term capacity for carbon sequestration as atmospheric CO2 increases.
Magnetic signatures of serpentinization at ophiolite complexes

Published: July 2016

AbstractWe compare magnetic properties of 58 variably serpentinized peridotites from three ophiolite complexes (Pindos, Greece; Oman; Chenaillet, France) and the mid‐Atlantic Ridge near the Kane fracture zone (MARK). The Pindos and Oman sites show low susceptibility and remanence (K < 0.02 SI; Ms < 0.4 Am2/kg), while the Chenaillet and MARK sites show instead high susceptibility and remanence (K up to 0.15 SI; Ms up to 6 Am2/kg), regardless of serpentinization degree. Petrographic observations confirm that Pindos and Oman samples contain serpentine with very little magnetite, while Chenaillet and MARK samples display abundant magnetite in serpentine mesh cells. Bulk rock analyses show similar amounts of ferric iron at a given serpentinization degree, suggesting that iron is oxidized during the serpentinization reaction in both cases, but that its distribution among phases differs. Microprobe analyses show iron‐rich serpentine minerals (5–7 wt % FeO) in low‐susceptibility samples, while iron‐poor serpentine minerals (2–4 wt % FeO) occur in high susceptibility samples. The contrasted magnetic properties between the two groups of sites thus reflect different iron partitioning during serpentinization, that must be related to distinct conditions at which the serpentinization reaction takes place. We propose that magnetic properties of ophiolitic serpentinites can be used as a proxy to differentiate between high temperature serpentinization (>∼250–300°C) occurring at the axis (i.e., Chenaillet, similar to serpentinites from magmatically poor mid‐ocean ridges), from lower temperature serpentinization (<∼200–250°C), likely occurring off axis and possibly during obduction (i.e., Pindos and Oman). At both settings, serpentinization can result in significant hydrogen release.

Authors: Liu Gongping , Jin Wanqin , Xu Nanping 
Published: July 2016

AbstractTwo‐dimensional (2D) materials of atomic thickness have emerged as nano‐building blocks to develop high‐performance separation membranes that feature unique nanopores and/or nanochannels. These 2D‐material membranes exhibit extraordinary permeation properties, opening a new avenue to ultra‐fast and highly selective membranes for water and gas separation. Summarized in this Minireview are the latest ground‐breaking studies in 2D‐material membranes as nanosheet and laminar membranes, with a focus on starting materials, nanostructures, and transport properties. Challenges and future directions of 2D‐material membranes for wide implementation are discussed briefly.

Published: July 2016

AbstractThis Minireview aims to give an introduction to beryllium chemistry for all less‐experienced scientists in this field of research. Up to date information on the toxicity of beryllium and its compounds are reviewed and several basic and necessary guidelines for a safe and proper handling in modern chemical research laboratories are presented. Interesting phenomenological observations are described that are related directly to the uniqueness of this element, which are also put into historical context. Herein we combine the contributions and experiences of many scientist that work passionately in this field. We want to encourage fellow scientists to reconcile the long‐standing reservations about beryllium and its compounds and motivate intense research on this spurned element. Who on earth should be able to deal with beryllium and its compounds if not chemists?
CO2 Activation and Hydrogenation by PtHn− Cluster Anions
Authors: Zhang Xinxing , Liu Gaoxiang , Meiwes‐Broer Karl‐Heinz , Ganteför Gerd , Bowen Kit 
Published: July 2016

AbstractGas phase reactions between PtHn− cluster anions and CO2 were investigated by mass spectrometry, anion photoelectron spectroscopy, and computations. Two major products, PtCO2H− and PtCO2H3−, were observed. The atomic connectivity in PtCO2H− can be depicted as HPtCO2−, where the platinum atom is bonded to a bent CO2 moiety on one side and a hydrogen atom on the other. The atomic connectivity of PtCO2H3− can be described as H2Pt(HCO2)−, where the platinum atom is bound to a formate moiety on one side and two hydrogen atoms on the other. Computational studies of the reaction pathway revealed that the hydrogenation of CO2 by PtH3− is highly energetically favorable.

Published: July 2016

AbstractIm Eisenbahnbrückenbau wird der Entwurf des Tragsystems sehr stark von der Gleis‐Tragwerks‐Interaktion geprägt. Im Teil 1 des vorliegenden Beitrags (Heft 2/2016) wurde die historische Entwicklung der Betrachtungsweise des Zusammenwirkens von Gleis und Tragwerk zusammengefasst. Weiterhin wurden die Grundsätze der Modellbildung zur Berechnung der Interaktionseffekte sowie die Interpretation der Berechnungsergebnisse vorgestellt. Im Teil 2 des Beitrags soll näher auf die Nachweisführung und insbesondere auf die Hintergründe der im Regelwerk verankerten Grenzwerte für die Kräfte und Verformungen im Gleis eingegangen werden. Es wird ersichtlich, dass die meisten im aktuellen europäischen Regelwerk gültigen Grenzwerte aus Untersuchungen der 1980er‐Jahre stammen. Eine Überprüfung und gegebenenfalls Anpassung ist dringend erforderlich. Eine Weiterentwicklung der Nachweisführung kann jedoch nur dann erfolgen, wenn die bisher bewährten Ansätze nachvollzogen und beurteilt werden können. Basierend auf einer umfangreichen Recherche wird in diesem Beitrag der Status quo beschrieben und Ansätze für die notwendigen Forschungsarbeiten zusammengetragen.Track‐bridge‐interaction – Part 2: backgrounds of the verification methodTrack‐bridge‐interaction has a major influence on the structural design of railway bridges. In the first part of this paper (see Vol. 93 (2016), No. 2) a brief overview describing the historical development of the consideration of the interaction effects has been given. Furthermore, basic principles of the calculation model as well as recommendations on how to deal with the results of the calculation has been presented. The aim of the second part of this article is to show the backgrounds of the verification scheme and especially to explain where the limit values for the additional rail stresses and deformations come from. It becomes apparent, that most rules contained in national and international codes are based on investigations carried out in the 1980s. An actualisation and further development of the codes is necessary, but can only be achieved if the well‐proven methods and limits used so far are well understood. This part of the article describes the actual status quo based on a literature research and gives outlines for future research needs.
