Tell the staff inside the polling station your name and address so they can check that you are on the electoral register. You can show them your poll card, but you do not need it to vote. The staff at the polling station will give you a ballot paper listing the parties and candidates you can vote for.
Now here is a key point: LOD Expressions allow you to determine the levels of detail (i.e., the dimensions) used in a calculation without actually dropping those dimensions into the visualization. You can define the level of detail at which a calculation should be performed, independently of the Viz LOD.
Loss on Drying (LOD) The classic laboratory method of measuring high level moisture in solid or semi-solid materials is loss on drying (LOD). In this technique a sample of material is weighed, heated in an oven for an appropriate period, cooled in the dry atmosphere of a desiccator, and then reweighed. If the volatile content of the solid is primarily water, the LOD technique gives a good measure of moisture content.
