International river basin organizations: variation,options and insights

Permanent international river basin organizations (IRBOs) come in many shapes and sizes, ranging from those which are mainly facilitative in nature to those empowered to act on their own. Although differences in IRBO types may have important impacts on transboundary water resources management, systematic analysis of variation in their structure and responsibilities is scant. This paper synthesizes and applies a typology to determine the structural composition, abundance, spatial distribution, scale and in-basin configurations of the different forms of IRBOs. The results provide a set of options for future IRBOs, and serve to ground-truth and nuance theoretical divisions between different types of organizations in transboundary basins.

“Stand B” reactor-laser system

A reactor-laser system, consisting of a BARS-6 double-core aperiodic pulsed reactor operating on fast neutrons and equipment for performing investigations of the laser radiation generation by direct nuclear pumping, is described. The neutron-physical characteristics of the reactor and the laser unit as well as the reactor-laser unit system are presented. The special features of the formation of fission pulses and the parameters of the pulses are indicated. 8 figures, 1 table, 12 references.

Formation of Manganese Silicide Films on Silicon

The formation of manganese silicide films during thermal annealing of Mn/Si structures is studied. The temperature range of silicide formation is determined. Between 400 and 800°C, the reaction between Mn and Si yields MnSi. The samples annealed at 800–1000°C consist of MnSi and the higher manganese silicide MnSi_1.75. Above 1000°C, the films consist of MnSi_1.75 and the metal-rich phase Mn₅Si₃.     

Variation of the rheological properties of multiphase mixtures during their pressure treatment
