The article presents the concept and development of an information system for environmental monitoring land parcels, that have already been robbed-out, are still being mined by open cut mining, through example research carried out on territory Kemerovo region - Kuzbass. paper system: data collection principle with use unmanned aerial vehicles, full attribute relational database model, which is ...

Property characterization of Chusquea culeou Desv. (colihue), a bamboo growing in Chile, was conducted. Physical, chemical and mechanical properties were determined as a function of plant diameter, position in culm length and nodal or internodal sections. The results show that fi bre length increased from the base to the top of the culms. Differences in the fi bre length between nodes and inter...

This study investigated the mechanical behavior and the variation of Dendrocalamus farinosus single fibres, which were isolated from fibre bundles using a chemical method. A micro-tester was applied to determine the influence of the age of the bamboo sampled, as well as the longitudinal and radial positions, on three indicators featuring tensile properties at the fibre level. The results indica...

Chromosomes were studied in somatic cells of 60 plants of blue grama, Bouteloua gracilis (Willd. ex Kunth) Lag ex Griffiths, collectedfrom a 7-hectarefield ofnative range at the Central Plains Experiment Range (CPER), Nunn, Colorado, to determine chromosome constitution in relation to the plant characteristics. Somatic chromosomes were studied in root tips collected from vigorously growingplant...
