A Review of the EUSO-Balloon Pathfinder for the JEM-EUSO Program.

is a pathfinder for , the mission concept of a spaceborne observatory which is designed to observe Ultra-High Energy Cosmic Ray (UHECR)-induced Extensive Air Showers (EAS) by detecting their UltraViolet (UV) light tracks "from above." On August 25, 2014, was launched from Timmins Stratospheric Balloon Base (Ontario, Canada) by the balloon division of the French Space Agency CNES. After reaching a floating altitude of 38 km, imaged the UV light in the wavelength range ∼290-500 nm for more than 5 hours using the key technologies of .

Semi-quantitative method for the assessment of debris supply from slopes to river in ungauged catchments.

This paper presents an integrated empirical methodology for assessing the amount of sediment transported from slopes to the main river in absence of a sediment transport monitoring system. The amount of transported sediment is calculated through the characterization of the sediment source areas including the identification of the slope phenomena responsible for the sediment propagation to the main river: shallow landslides, channelized debris flows and deep-seated rotational slides. On this basis, several scenarios related to the climatic conditions are defined: they indicate the number of possible slope phenomena and potential volumes of mobilized unconsolidated material from sediment source areas to the main river.

Impact of TiO₂ nanoparticles on Vicia narbonensis L.: potential toxicity effects.

This work was aimed to provide further information about toxicology of TiO2 nanoparticles (NPs) on Vicia narbonensis L., considering different endpoints. After exposure to TiO2 nanoparticle suspension (mixture of rutile and anatase, size <100 nm) at four different concentrations (0.

The intergenic spacer region of the rDNA in Haplopappus gracilis (Nutt.) Gray.

In this paper, we provide further information on the genome organisation of Haplopappus gracilis, one of the six angiosperms showing the lowest chromosome number, i.e. 2n = 4, by determining the nucleotide sequence of the intergenic spacer region of the ribosomal RNA genes and its cytological localization on metaphase chromosomes.

Cytological and molecular characterization of Vicia barbazitae Ten. & Guss.

Vicia barbazitae, a taxon belonging to section Vicia of subgenus Vicia, was recovered and analysed by cytological, karyological and molecular methods with the aim of both proposing a general characterisation of this species and studying the relationships among the species of section Vicia . Phylogenetic relationships among the species of the section Vicia and those of the sections Microcarinae, Wiggersia and Atossa were also analysed. Automated karyotype analysis has been determined after Feulgen's reaction; chromosome banding was performed by sequence-specific fluorochrome staining.
