During the All Taxa Biodiversity Inventory + Monitoring programme (ATBI+M) in the Mercantour and Alpi Marittime National Parks, our inventories of bryophytes identified 234 taxa (mosses and liverworts). This work completes the previous field campaigns, notably those of Jean-Pierre Hebrard (I MEP, Marseille) since 1965, and the ATBI bryophyte inventories in 2007. This number is based on four days of inventories in the central and peripheric territory of both National Parks, in four days in July and August 2010, together with previous data the 565 taxa known from the area still underestimate the number of species actually present. Our observations in 2010 added several new species for this area, including several rare and remarkable species such as Haplomitrium hookeri or species listed under the Habitats Directive as Buxbaumia viridis and Orthotrichum rogeri. Given the rarity of their habitats species from snow beds, large block boulders and high altitude wetlands are most remarkable. [less ▲]

Nous développons un modèle dans lequel les travailleurs peuvent avoir tendance à trop travailler quand ils sont jeunes, parce qu’ils ne peuvent ou ne veulent pas voir les conséquences que cela peut avoir sur leur santé et sur leur capacité à travailler longtemps. Pour les obliger à mieux répartir leurs efforts sur leur cycle de vie, une taxe sur les revenus du travail en début de vie et une subvention de l’épargne sont souhaitables. Si la subvention de l’épargne n’est pas disponible, la taxe optimale arbitre entre quatre considérations différentes. Nous étudions également la taxe optimale quand les individus diffèrent en productivité. [less ▲]

Regression is a commonly used technique for describing the relationship between a response variable and one or more explanatory variables. When the response variable is a categorical variable, usual regression based on ordinary least squares should be replaced by logistic regression. Binary logistic regression should be used to perform a regression on a dichotomous response. Nominal polytomous logistic regression applies to a categorical response variable that has more than two levels with a natural ordering. And ordinal polytomous logistic regression is used when the response is a categorical variable that has more than two levels with a natural ordering. This note gives an overview of these logistic regression methods and describes three models commonly used when performing ordinal logistic regression. These models are illustrated by an example related to oak decline in the Walloon Region (Belgium). [less ▲]

Bone fracture healing is a complex process in which angiogenesis or the development of a blood vessel net work plays a crucial role. In this paper, a mathematicalmodel is presented that simulates the biological aspects of fracture healing including the formation of individual blood vessels. The model consists of partial differential equations, several of which describe the evolution in density of the most important cell types, growth factors, tissues and nutrients. The other equations determine the growth of blood vessels as a result of themovement of leading endothelial (tip) cells. Branching and anastomoses are accounted for in the model. The model is applied to a normal fracture healing case and subjected to a sensitivity analysis. The spatiotemporal evolution of soft tissues and bone, as well as the development of a blood vessel network are corroborated by comparison with experimental data. Moreover, this study shows that the proposed mathematical framework can be a useful tool in the research of impaired healing and the design of treatment strategies. [less ▲]

Pharmaceutical counterfeiting is a permanently growing problem. Control laboratories are constantly analysing counterfeit medicines. In industrialised countries, one of the main counterfeited class of medicines are erectile dysfunction drugs. This paper describes the development and validation of a fast method to detect and quantify the three authorised phosphodiesterase type 5 inhibitors and five analogues. The method is based on the use of a sub-2 microns polar-embedded column with a gradient using acetonitrile as organic modifier and 10 mM ammonium formate buffer (pH 3.5) as aqueous component of the mobile phase. The separation was achieved in less than 4.5 min. The method has also been compared to the registered HPLC method for the assay of Viagra® which was considered as the reference method. The method is also compatible with on-line coupling mass spectrometry and will significantly reduce analysis times and solvent consumption. [less ▲]

Analysing spatial familiarity aims to measure how places included in the life-world and in the cognitive map are familiar. Based on the study of Gale, Golledge, Halperin & Couclelis (1990), this paper explores the spatial familiarity of the inhabitants of two municipalities at the fringe of Liege (Belgium): it questions the links between the cognitive dimensions (visual, nominal, localisation) and themselves and the behavioural dimension (passing). It seeks new relevant places for the population of these urban fringe as well as the favourable factors to a good familiarity of a place. Finally, it scrutinizes the influence of people's mobility – period of residence, commuting to work, modes of transport – on spatial familiarity. [less ▲]
