We investigate genuinely entangled N-qubit states with no N-partite correlations in the case of symmetric states. Using a tensor representation for mixed symmetric states, we obtain a simple characterization of the absence of N-partite correlations. We show that symmetric states with no N-partite correlations cannot exist for an even number of qubits. We fully identify the set of genuinely entangled symmetric states with no N-partite correlations in the case of three qubits, and in the case of rank-2 states. We present a general procedure to construct families for an arbitrary odd number of qubits. [less ▲]

The genus Biernatella (Brachiopoda; Athyridida), characterized by the presence of a diplospiralium, is definitely recognized for the first time in the late Frasnian (Lower-Upper Palmatolepis rhenana Zones) of the southern flank of the Dinant Synclinorium and of the Philippeville Anticlinorium (southern Belgium). A new species (B. abunda n. sp.) from the Neuville Formation (Dinant Synclinorium) is described. In the Philippeville Anticlinorium, B. abunda n. sp. occurs in the Neuville Formation and probably at the base of the Les Valisettes Formation but specifically unidentified specimens of Biernatella have also been collected near the top of this last formation.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Psiadia Jacq. ex. Willd. belongs to the Asteraceae family and includes more than 60 species. This genus grows in tropical and subtropical regions, being especially well represented in Madagascar and the Mascarene Islands (La Reunion, Mauritius and Rodrigues). Several Psiadia species have been used traditionally for their medicinal properties in Africa and the Mascarene Islands. Based on traditional knowledge, various phytochemical and pharmacological studies have been conducted. However there are no recent papers that provide an overview of the medicinal potential of Psiadia species. Therefore, the aim of this review is to provide a comprehensive summary of the botany, phytochemistry and pharmacology of Psiadia and to highlight the gaps in our knowledge for future research opportunities. MATERIALS AND METHODS: The available information on traditional uses, phytochemistry and biological activities of the genus Psiadia was collected from scientific databases through a search using the keyword 'Psiadia' in 'Google Scholar', 'Pubmed', 'Sciencedirect', 'SpringerLink', 'Web of Science', 'Wiley' and 'Scifinder'. Additionally, published books and unpublished Ph.D. and MSc. dissertations were consulted for botanical information and chemical composition. RESULTS: Historically, species of the genus Psiadia have been used to treat a wide range of ailments including abdominal pains, colds, fevers, bronchitis, asthma, rheumatoid arthritis, skin infections and liver disorders among others. Phytochemical works led to the isolation of flavonoids, phenylpropanoids, coumarins and terpenoids. Furthermore, phytochemical compositions of the essential oils of some species have been evaluated. Crude extracts, essential oils and isolated molecules showed in vitro pharmacological activities, such as antimicrobial, anti-viral, anti-inflammatory, antiplasmodial and antileishmanial activities. Crude extracts of Psiadia dentata and Psiadia arguta have specifically been found to be potentially useful for inhibition of growth of Plasmodium falciparum. However, pharmacological data on this particular genus is quite limited. Further research is necessary to determine the active compounds and the underlying mechanisms. [less ▲]

In hydrogeology, advances in the delimitation of protection zones are made by the use of stochastic simulations integrating all available data. In practice, due to the few available measurements of the main parameters (hard data), it is very useful to integrate several secondary properties of the media as indirect data (soft data) to reduce the uncertainty of the results. In aquifers, most of the solute spreading is governed by the hydraulic conductivity (K) spatial variability, which is generally considered as the main uncertain parameter. A stochastic approach integrating hydraulic conductivity measurements (hard data), head observations and shallow electrical resistivity tomography (soft data) is presented. Results are discussed on a synthetic and on a practical case. It is shown in practice how the uncertainty of the well capture zone probability distribution (CaPD) can be reduced. Since geophysical data and head observations are easier to collect on the field then hydraulic conductivity measurements, they are generally more abundant. The methodology presented can even be used in real applications when little or no information is available about the hydraulic properties, through the conditioning on geophysical data and/or head observations.

In Belgium, forests cover about 670.000 hectares. The corresponding data are issued from various sources: non-forest thematic maps, total tallies, sample surveys and remote sensing. At the national level the official information is given by decennial national forest statistics but because of its lack of uniformity and quality other approaches are necessary. The Flemish region (northern par of Belgium with 20 % of the forest) is using remote sensing to assess the global forest situation while the Walloon region (southern part of Belgium with 80 % of the forest) is using a permanent field forest inventory based on a sampling frame (1 plot for every 50 hectares located in forest conditions). GIS are on the way to bringing together pertinent geo-referenced data on vegetation, soil growing stock and environmental conditions. This report outlines the procedures used to obtain basic information on the location and extend of the forest resource. [less ▲]

The Phoenician Utica remains today largely unknown, as well as the role that the ancient city held in the Phoenician expansion in the western Mediterranean. Aristotle and Pliny the Elder mentioned Utica as a maritime and port city and evaluate its origin around the 11th c. BC.. However, in the present state of research, no archaeological evidence goes back beyond the 7th c. BC.. Today, the ancient port city is located in the heart of the Medjerda delta, 10 km inland. Although the Utica site has been the subject of archaeological excavations since the 19th c., the location of port infrastructures, dating from Phoenician and Roman periods, remains unknown. Based on this observation, our research focuses on two main issues: Where are the port infrastructures of Utica? Why the city, formerly a seaport city, is today located 10 km from the coast? The location and the study of port infrastructures will bring primordial elements of response to the question of the city founding. The study of river paleoenvironments of the Medjerda delta during the Holocene aim to a better understanding of the nature of the settlement, as well as the function of the city of Utica. This study will also assess the impact of the ancient city on the environment and understand how the city has adapted to the mobility of this Mediterranean delta. Furthermore, the study of sedimentary processes causing the filling of the harbour basin will lead to speculate about the causes of the abandonment of the structures and more generally the decline of the city in favor of the city of Carthage. It will also detect if natural or anthropogenic factors have influenced this deltaic progradation over the centuries. This project proposes an interdisciplinary reflection to understand the Medejerda delta landscape changes during the Holocene. It starts from an archaeological problem and proposes the contribution of geoarchaeology to the understanding of the relationship between ancient societies and their environment. A major originality of this project lies in the multidisciplinary approach, which aim to provide an evolutive image of the landscapes of the Medjerda watershed, and to precise the sedimentary record considering control variables such as climate and anthropogenic pressure. The study of fluvial palaeoenvironments and sedimentary processes will be carried out through the mechanical extraction of cores (~10 m deep) to reach the early Holocene. Selected sediment samples will then be studied in laboratory, using different and complementary approaches. Particle size analysis and quartz morphoscopy will help to clarify the processes involved in the successive phases of deposits associated with different sedimentary environments. It will be supplemented by a series of sedimentological (magnetic susceptibility, mineralogy, organic and inorganic geochemistry) and biological analyses (pollen, ostracods) to reconstruct the evolution of the landscape over the last millennia. This reconstruction will be related to climate changes during the Holocene. The combination of mineralogical and geochemical approaches will help to identify the origin of clay minerals to determine their source regions and to highlight contamination by human activities. The influence of anthropogenic factors will be confirmed by analysing lead isotopes. Meanwhile, a series of radiocarbon dating will be conducted to establish the chrono-stratigraphic framework of the different evolution phases of the delta. More generally, this project focuses on the importance of knowledge of the past to understand and grasp the consequences of the human impact on the environment, more specifically on the deltaic environments.

Phoenician Utica remains today largely unknown, as is its role in the Phoenician expansion in the western Mediterranean. Aristotle and Pliny the Elder mention Utica as a maritime and port city and estimate its origin around the 11th c. BC. However, in the present state of research, no archaeological evidence is earlier than the 9th c. BC, and the location of the Phoenician and Roman port infrastructures remains unknown. Today, the ancient city is located on a promontory in the heart of the Medjerda delta, 10 km inland. This project proposes an interdisciplinary effort to understand the Medjerda delta landscape changes during the Holocene. It starts from an archaeological problem and proposes the contribution of geoarchaeology to the understanding of the relationship between ancient societies and their environment. The fluvial palaeoenvironments and sedimentary processes are studied through the mechanical extraction of cores (15-20 m deep) to reach the early Holocene. Selected sediment samples are then studied in laboratory, using different and complementary approaches. The location of port infrastructures will bring initial answers to the question of the foundation of the city. The study of river palaeoenvironments of the Medjerda delta during the Holocene aim at a better understanding of the nature of the settlement, as well as the function of the city of Utica over time. This study will also assess the impact of the ancient city on the environment and understand how the city adapted to the mobility of this Mediterranean delta. Furthermore, the analysis of sedimentary processes causing the filling of the harbour basin will lead to speculation about the causes of the abandonment of the structures and more generally the decline of the city in favor of Carthage.

Ancient authors mention Utica as a maritime and port city and estimate its origin around the 11th c. BC. However, in the present state of research, no archaeological evidence is earlier than the 9th c. BC, and the location of the Phoenician and Roman port infrastructures remains unknown. Today, the ancient city is located on a promontory in the heart of the Medjerda delta, 10 km inland. Based on this observation, our geoarchaeological research focuses on two main issues: - Was there a marine environment around the promontory of Utica, which could shelter harbour structures? - Why the city, formerly a seaport city, is today located 10 km from the coast? Can the wadi be solely responsible of such an important sediment accumulation in a few millennia? Have any natural or anthropogenic factors influenced this deltaic progradation over the centuries? First results permitted drawing an hypothesis of the coastline during Antiquity to the effect that the Utica promontory was surrounded by the sea in an earlier era. (1) Effectively, the «North compartment» of the delta was covered by the sea at a given time, which will be determined by the next radiocarbon dating. But the sea still brushed the north side of the promontory during the Roman period, as evidenced by the potsherds found in one of the cores. This deep marine bay could be a potential location for harbour infrastructure prior to clogging of the bay by the sediments carried by the wadi. (2) The «corridor» area, materialised by the promontories of Utica and Kalâat el-Andalous, was also invaded by the sea at one time. The many artifacts found in this core attest the occupation of this area, outside of the maximal extension of the ancient city according to A. Lézine. Dating of the marine units in the two cores will bring essential data: * to establish the chronological framework of the retreat of the coastline and of the clogging of the bay; * to understand the passage of the Medjerda into the «North compartment» by the corridor Utica-Kalâat. The geoarchaeological results corroborate ancient sources. Utica was able to welcome important harbour structures, since the presence of a deep marine environment is attested around the promontory, but these remains are probably 5 m deep under the alluvium of the Wadi Medjerda.
