Late Middle Triassic to early Late Triassic insects from Argentina have been previously described from the Bermejo and Cuyana Basins where they have been recovered from the Ischichuca-Los Rastros and Potrerillos-Cacheuta formations, respectively. The insect fauna discussed herein was collected during field studies in 1986/1987 from the Llantenes section （Norian to Rhaetian？ Late Triassic）, which is situated in the Malargiie Basin in southern Mendoza province. The insect remains were found in the upper part of the Llantenes section （Llantenes formation）, which is built up of two coarsening-upwards cycles reflecting a deltaic progradation of a fluvial into a lacustrine environment （lower part）, succeeded by repeated progradatious into a floodplaindominated environment （upper part; with finds of insects, conchostracans, fish remains, plant fragments, and drifted logs）. The new finds represent the youngest Triassic insect records described from Argentina and even from South America in its entirety. There is only one contemporaneous fossil assemblage in Gondwana： in the Ciarence/Moreton Basin （Aberdare Conglomerate; Late Norian） in Australia. The new Triassic insects include an impression of an isolated Mecopterida-like wing （Mendozachorista volkheimeri gen. et sp. nov.; Mendozachoristidae fam. nov.）, coleopteran elytra of the Permosynidae （Ademosyne rosenfeldi sp. nov. and Ademosyne Uantenesensis sp. nov.） and other isolated body fragments. This new Late Triassic entomofauna from Argentina is of considerable importance in the reconstruction of the biotic recovery of continental environments in Gondwana after the catastrophic mass extinction at the P/T boundary.

作者： E. gallego f. X. Roca X. Guardino M. G. Rosell Environmental Centre Laboratory Polytechnic University of Catalonia (LCMA-UPC) National Centre of Work Conditions (INSHT)

five aromatic hydrocarbons (benzene, toluene, and three isomeric xylenes) were monitored in indoor and outdoor air of 7 public buildings and 54 private homes, located in Barcelona City metropolitan area and in several rural areas of Catalonia. The sampling was carried out over four periods: spring-summer and winter of 2000, and summer and winter of 2001. Passive ORSA 5 Dra¨ger samplers were used for benzene, toluene, and xylenes (BTX) adsorption. BTX were extracted with carbon disulphide and analysed using ...

Values for particle-scale properties of biomass briquettes made from agroforestry residues

引用

Particuology 2014年第1期12卷 100-106页

The production of biomass pellets and briquettes from agroforestry residues has increased rapidly in recent years. The design of machines, equipment and the infrastructure necessary for the handling, trans port and storage of these products has been an engineering challenge since, when moving, biomass does not usually flow as easily as other granular materials. The discrete element method （DEM） provides a means of studying the handling and silo discharge behaviour of granular solids as well as the distribution of the pressures exerted by such materials in silos. However, the development of such models requires certain properties of the particles in question to be known. The present work experimentally determines the true density, Young＇s modulus of elasticity （axial and radial）, the particleparticle restitution coeffi cient and the particlewall friction coefficientall variables that must be known in the construction of DEM modelsfor briquettes made from maize stalk, maize stalk plus pine wood chips, rice husk, vine shoots, raoe straw, cereal straw and sawdust olus cereal straw.
