Timber nomenclature

Timber Cycles *

We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...

A new nomenclature for fungi

Important changes brought about by the Melbourne International Code of Nomenclature for Algae,FungiandPlantsare briefly reviewed concerning a clarification of the spelling and typification of sanctioned fungal names, the recognition of electronic publication for the validity of nomenclatural novelties, permission to use English diagnoses or descriptions for their valid publication, and the requ...

Timber Management Planning with Timber RAM and Goal Programming

By using goal programming to enhance the linear programming of Timber RAM, multiple decision criteria were incorporated in the timber management planning of a National Forest in the southeastern United States. Combining linear and goal programming capitalizes on the advantages of the two techniques and produces operationally feasible solutions. This enhancement may also be applicable to linear ...

Allergen nomenclature.

This article presents a nomenclature system for allergens which has been officially recommended by the International Union of Immunological Societies (IUIS). The nomenclature is based on proposals of the IUIS Sub-Committee for Allergen Nomenclature and is applicable to highly purified, well-characterized allergens and to non-purified or partially purified allergenic extracts.
