In this chapter, we review the general properties of STMDs and consider the performance of a STMD in two different dynamic regimes of detector operation: in the well-known traditional in-plane regime of STMD operation and in the recently discovered novel out-of-pla

Experimental results obtained by spin-polarized electron energy loss spectroscopy will be presented. The focus will be on the basic concepts and the

Aquatic bryophyte assemblages along a gradient of regulation in the river Rhineeased or disappeared. The industrial development along the river has caused water quality to severely decrease downstream of the industrial areas, hence the decrease or the disappearance of their primary flora in favour of pollution-tolerant assemblages. The former side channels of the Upper Rhine i

This macrophyte sequence corresponded to an upstream to downstream zonation, which was characterized by an increase in buffer capacity and in nutrient levels and a decrease in protons and alumi

Use of oligochaete communities for assessment of ecotoxicological risk in fine sediment of rivers an have an important role by sorbing metals leading to lower availability. Macrophyte cover could also explain some conflicting results. Granulometrics does not play a determinating role in the present case. As a conclusion, a table allowing the classification of river sediments is proposed for monito
