Developing dynamic adaptive policy pathways: A computer-assisted approach for developing adaptiv strategies for a deeply uncertain world

Sustainable water management in a changing environment full of uncertainty is profoundly challenging. To deal with these uncertainties, dynamic adaptive policies that can be changed over time are suggested. This paper presents a model-driven approach supporting the development of promising adaptation pathways, and illustrates the approach using...

To Recycle or Not to Recycle? An Intergenerational Approach to Nuclear Fuel Cycles

AbstractThis paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and...

The use of karyotyping in the systematics of yeasts

The use of electrophoretic karyotyping in systematics of yeasts is discussed. New data are provided on the karyotypes of the medically important fungiHortaea werneckii, Filobasidiella (=Cryptococcus)neoformans, andMalassezia species.Hortaea werneckii has twelve to eighteen bands of chromosomal DNA, ranging in size between 500 and 2300 kb. The...

Some observations on air filtration

1. A method has been developed for testing the filtration efficiency of some filter materials. For each of the materials investigated — cotton wool, stillite and carbon — a suitable filter has been devised. 2. The filtered air was analyzed as to its germ content with the aid of a set of 3 capillary impingers. 3. The cotton wool filter gave on...
