Preparation of acetate peels of valves from the ocean quahog, Arctica islandica, for age determinations

Techniques are described for preparing acetate peels of sectioned valves of ocean quahogs, Arctica islandica, for age determinations. The respective sequence of preparation begins by sectioning left valves oriented to include a single hinge tooth, bleaching to remove the heavy periostracum, embedding the valves in an epoxy resin, grinding and polishing the embedments to a high luster, etching the exposed cut valve surfaces, and applying sheet acetate with acetone. Annuli are clearly defined relative to growth increments in the peel preparations for all sizes and ages of ocean quahogs. (PDF file contains12 pages.)

Notes for guidance on preparation of research reports, research dissertations and scientific papers

The notes for guidance on preparation of research, research dissertations and scientific papers are meant to assist researchers on how to achieve a successful presentation, writing a technical report or research paper. This comprises some simple rules that have helped many inexperienced writers to get started, and have also helped more experienced writers to get out of a hopeless tangle of observations and inferences.

Preparation for implementing the proposed EC Water Framework Directive in Finland

Finland reorganised its environmental administration in 1995 when thirteen Regional Environmental Centres (RECs) and one national agency called the Finnish Environment Institute (FEI) were created. The REC's and the FEI have been entrusted with functions related to water resources management. RECs and FEI together with the Ministry of Agriculture and Foresty have appointed a steering group which will supervise the implementation of the EC Water Framework Directive in Finland
