 # # Example 2. Alloying elements in recycling.
+# *ODYM example by Stefan Pauliuk, adapted for sodym*
 #
 # A recycling system with two end-of-life (EoL) products, two scrap types, one secondary material, and several types of losses are studied. Three chemical elements are considered: iron, copper, and manganese. A time horizon of 30 years [1980-2010], five processes, and time-dependent parameters are analysed. The processes have element-specific yield factors, meaning that the loss rates depend on the chemical element considered. These values are given below.

 # # Example 3. Dynamic Stock modelling
+# *ODYM example by Stefan Pauliuk, adapted for sodym*
 #
 # sodym defines the class DynamicStockModel for handling the inflow-driven and stock driven model of in-use stocks, see methods section 3 of the [uni-freiburg industrial ecology course](http://www.teaching.industrialecology.uni-freiburg.de/). In this notebook, we show how the dynamic stock model is used in the sodym framework. Other methods of the dynamic_stock_modelling class can be used in a similar way.
