- people in the same age range
- What is the average age of this class?
- One's view is determined by his education, sex, class and age.
- Age class 3
- Age class 8
- Age class 1
- Age class 4
- Population demographic characteristics (e.g. body size or age class structure, sex ratio, fecundity rates, survival/mortality rates) (1.3.1)
- STECF has estimated the strength of the 2005 year-class to be not less than 324000 million individuals at age 0.
- For the analysis of major elements and Fe, Mn, Zn, Cu, the recommended quantity is 30 grams of fresh needles or leaves for each sampled age class.
- The chlorotic mottling will be scored for each needle age class (from current year's (C) to 3-year old (C+2) needles) in percentage of total surface affected by locating all needles of one age class forming a surface, and then the corresponding score (classes) for that percentage will be assigned, according to the following table.
- where STECF estimates the size of the 2004 year class of North Sea sandeel to be at or above 500000 million individuals at age 0, no restrictions in kilowatt-days shall apply for the remaining of 2005;
- composition (fat content, dry matter content, water content in the non-fatty matter), quality class, age or maturing stage, presentation and packing conditions (e.g. in bulk, in 25 kg sacks), other characteristics
- Those cases shall, as a minimum, include the transfer of class of ships of 15 years of age or over and the transfer from a non-recognised organisation to a recognised organisation.
- If this part of the tree is not accessible, use part of the branches collected for foliar analysis. The chlorotic mottling will be scored for each needle age class (from current year's (C) to 3-year old (C+2) needles) in percentage of total surface affected by locating all needles of one age class forming a surface, and then the corresponding score (classes) for that percentage will be assigned, according to the following table.
- The scores shall be produced per needle class; thus trees (and species) will have separate scores for the needles of age-classes C, C+1, C+2, etc. The final score of an individual tree shall be the score corresponding to the average injury percentage of a given needle year-class for that tree (this is obtained by averaging the injury percentages of all individual needle-whorls of a given age-class on that tree); similarly, the final score for the plot shall be the score corresponding to the average of the injury percentages of all sampled trees.
