Many of these fibres, such as straws, reeds and bagasse, are similar in length to the short fibre hardwoods. On the other hand, others such as flax and hemp are so long that they have to be shortened prior to papermaking (Atchison 1987). From a quality point of view, any grade of paper can be produced by the combination of different non-wood plant fibres (Atchison & McGovern 1987).

In some grammars, for instance, pronouns are treated as a separate word class, whereas we treat them as a subclass of nouns. A difference like this should not cause confusion. Instead, it highlights an important principle in grammar, known as GRADIENCE. This refers to the fact that the boundaries between the word classes are not absolutely fixed.

  • Epidemiological studies about contagious diseases have two very specific characteristics. The first refers to the object, which is only a source of damage. The second relates to the goals, which aim to determine the relationship between cause and effect, i.e., between exposure and disease.
