For an incompressible, isothermal, continuous and frictionless flow, the exact resolution of the equation of conservation of mechanical energy is equivalent to the exact resolution of the equation of momentum conservation. However, the discrete solution of the equation of momentum conservation does not verify the equation of energy conservation. This is particularly the case as a result of the presence of a non-conservative bed slope term in the equation of momentum conservation. In this research, the influence of (i) the formulation and (ii) the discretization scheme of the non-conservative bed slope term on the energy conservation is analysed in the case of a 1D horizontal and frictionless channel with a topographic step. The results for two different formulations of the bed slope term are firstly compared: the standard formulation of the bed slope source term and a divergence formulation of the bed slope term. Then, different discretization schemes of the divergence formulation of the bed slope term are analyzed to determine the one minimizing the numerical variation of energy. [less ▲]

Trends in the vertical distribution of ozone are reported and compared for a number of new and recently revised datasets. The amount of ozone-depleting compounds in the stratosphere (as measured by Equivalent Effective Stratospheric Chlorine – EESC) maximised in the second half of the 1990s. We therefore examine the trends in the periods before and after that peak to see if any change in trend is discernible in the ozone record. Prior to 1998, trends in the upper stratosphere (~ 45 km, 4 hPa) are found to be −5 to −10% per decade at mid-latitudes and closer to −5% per decade in the tropics. No trends are found in the mid-stratosphere (28 km, 30 hPa). Negative trends are seen in the lower stratosphere at mid-latitudes in both hemispheres and in the deep tropics. However it is hard to be categorical about the trends in the lower stratosphere for three reasons: (i) there are fewer measurements, (ii) the data quality is poorer, and (iii) the measurements in the 1990s are perturbed by aerosols from the Mt. Pinatubo eruption in 1991. These findings are similar to those reported previously even though the measurements for the two main satellite instruments (SBUV and SAGE II) and the ground-based Umkehr and ozonesonde stations have been revised. There is no sign of a continued negative trend in the upper stratosphere since 1998: instead there is a hint of an average positive trend of ~ 2% per decade in mid-latitudes and ~ 3% per decade in the tropics. The significance of these upward trends is investigated using different assumptions of the independence of the trend estimates found from different datasets. The averaged upward trends are significant if the trends derived from various datasets are assumed to be independent, but are generally not significant if the trends are not independent. This arises because many of the underlying measurement records are used in more than one merged dataset. At this point it is not possible to say which assumption is best. Including an estimate of the drift of the overall ozone observing system decreases the significance of the trends. The significance will become clearer as (i) more years are added to the observational record, (ii) further improvements are made to the historic ozone record (e.g. through algorithm development), and (iii) the data merging techniques are refined, particularly through a more rigorous treatment of uncertainties.

Given a worldwide preference for suffixes over prefixes, why do some languages nonetheless have a macro-preference for prefixes? In this talk, we show that Ancient Egyptian-Coptic (Afroasiatic) shows a long-term diachronic macro-change from mixed suffixing-prefixing to an overwhel¬ming preference for prefixing. We argue that each of the micro-changes implicated in this macro-change are better understood in terms of regular changes at the level of individual constructions, via, e.g., grammaticalization, rather than in terms of a broad Sapirian ‘drift.’ Crucially, it is the particular constellation of structural features of the language at a particular moment in time, together with regular mechanisms of language change, that give rise to the cross-linguistically unusual ‘macro-preference’ of the language.

Die deutschsprachigen Belgier betrachten ihre jüngere Geschichte zumeist aus der Perspektive einer Minderheit. Die Erinnerung an den Ersten Weltkrieg vor hundert Jahren bietet Christoph Brüll den Anlass, sich mit der damals wohl kleinsten Minderheit des deutschen Kaiserreiches zu befassen: den rund 10.000 „preußischen Wallonen“ im Kreis Malmedy. Der Vortrag fragt nach deren Identität im Kaiserreich, wo sie zu Kollateralopfern der gegen größere Minderheiten gerichteten Germanisierungspolitik wurden, woraus ein wallonischer Kulturpartikularismus an der deutsch-belgischen Grenze resultierte. Dabei wird auch die Offenheit dieser Grenze vor dem August 1914 deutlich, die durch intensive grenzüberschreitende soziale, wirtschaftliche und auch kulturelle Kontakte gekennzeichnet ist. Umso dramatischer wurde dort der Beginn des Ersten Weltkriegs empfunden. Die Haltung der Bevölkerung während dieses Kriegs ist jedoch von der Forschung bisher kaum in den Blick genommen worden. Der Prozess einer sich beschleunigenden Nationalisierung der kleinen Region und die Reaktion der Bevölkerung darauf werden anhand verschiedener Aspekte wie Militär, Kirche und Schule dargestellt. Der Vortrag geht auch auf die Erfahrung des Kriegsendes und der darauf folgenden Besatzungszeit durch britische Truppen, die im August 1919 von belgischen Soldaten abgelöst wurden, ein. Nicht zuletzt unternimmt er den Versuch, die Entwicklung der Jahre 1914-1920 nicht von ihrem Ende – d.h. aus der Sicht des Staatenwechsels von 1920 – zu betrachten, womit die Kriegs- und Nachkriegserfahrung der Bevölkerung in den Mittelpunkt der Betrachtung rückt .

Conservation of large wildlife species is currently a major issue in Africa. Protected areas dedicated for biodiversity conservation unfortunately do not suffice and conservation practices must be extended to man-used areas. But in those areas conservation actions are limited because of conflicts between human and wildlife especially due to damages on crops. The worst crop raiders known are elephants because they can destroy the yearly harvest of a field in a single visit. This threatens not only people livelihoods but also elephants themselves when angry farmers retaliate by shooting or trapping them. After decades of investigations crop raiding drivers related to elephants’ ecophysiology remain largely unknown. A pilot study was conducted between July and November 2014 in Monts de Cristal National Park (Gabon, central Africa) to have a first view on environmental drivers to crop raiding. While the presence of some fruiting trees around crop fields lead to more damages, high slopes discouraged elephants. In further experiments, the link between the nutritive value of raided plants and the animal’s physiological requirements and status will be assessed through hormones and parasites measurements; while tracking of individual elephants’ movements using DNA analyses in feces will be done.

This work is a part of the Master of Science Thesis written during the mobility organized by the Erasmus + Programme for exchange students at Universite de Liege, in Belgium (Université de Liège, Belgique), which is in bilateral agreement with Technical University of Cluj-Napoca, in Romania (Universitatea Tehnica din Cluj-Napoca, România) available between 2014 – 2020. The audience of this technical report is civil engineers and specialists in building energy and it aims to inform about the content of the standards for building energy performance used in Romania. The report presents the essential information of the Romanian standards for building energy performance, such as the calculation of the global thermal insulation coefficient or the annual heating demand, along with some critical aspects regarding the efficiency of the standards and their alignment with the European requirements and regulations. The original content of the standards is found in the official language Romanian and is published in the special law publication from Romania named Monitorul Oficial al României. The legislative body that approved the publication of the Romanian energy performance standards C107 – 2005, Mc001 – 2006, C107/6-02 and C107-02, along with their annexes and modifications is the Ministry of Transport, Constructions and Tourism (Ministerul Transporturilor, Construc iilor i Turismului). The content of the standards was elaborated by the following Romanian institutions: The University of Architecture and Urban Planning “Ion Mincu” – Bucharest (Universitatea de Arhitectura i Urbanism ”Ion Mincu” – Bucure ti), The Institute for Research in Buildings and Building Economy – Bucharest (Institutul de Cercetari în Construc ii i Economia Construc iilor INCERC – Bucure ti), The Associastion of the Building Service Engineers from Romania (Asocia ia Inginerilor de Instala ii din România – AIIR) and The Technical University of Civil Engineering – Bucharest (Universitatea Tehnica de Construc ii – Bucure ti).

Thanks to a partial manual mapping between ICPC2 and MeSH, it is now also possible to query PubMed from 20% of ICPC2 codes. This task is time consuming as in lot of cases, the mapping is 1 to N (one ICPC code generates several MeSH terms; e.g. the ICPC term "diverticular disease" is mapped to two MeSH terms " diverticulosis, colonic" and " diverticulitis". HeTOP currently contains 56 health terminologies and ontologies (only 17 are included in UMLS as most of them are French terminologies), 1,951,834 concepts, 6,636,000 terms, 8,023,181 relations and 1,340,855 relations. Overall, HeTOP contains 108 millions of SPARQL triplets. These figures underlines the possible application of the so called "health big data".

In the Western Highlands agro-ecological zone of Cameroon, rivers are constantly silted and polluted with eroded sediment and waste from cultivated land. This study characterizes and quantifies the amount of material coming from plots cultivated in the Méloh Watershed. In a natural rocky-bottomed well measuring 0.90 m deep, 3 m long, and 2.5 m wide, for a period of three years we performed the collection, differentiation, and measurement of trapped sediment in the cultivated part of river that runs through the watershed. Both cultivated sides of the watershed had fairly regular slopes of 14% on one side and 17% on the other side. The material retrieved consisted of soil, plant residues, chemical packages, and plastic casing used for irrigation. During the years 2012 and 2013, farmers practiced both flatbed cultivation and ridging along the steepest slopes. These two methods of land preparation are inefficient in terms of water conservation, as evidenced by the collection of 10.429 t.ha-1 average total sediment per year during this period. Tied ridging cultivation method was experimented during the 2013 crop year and adopted on 75% of plots in 2014. We subsequently collected 3.586 t.ha-1 total sediment, a decrease of 65.61% compared to the average of previous years. The tied ridging cultivation method significantly reduced siltation of the Méloh River (p<0.05). This study showed that traditional agricultural practices are a principal cause of siltation and pollution of the Méloh River. By extrapolation, we can state that the problem must occur in almost all rivers in the study area with similar topography and agricultural practices [less ▲]
