In theater, the tableau takes on an entirely different dimension. It serves as a staging technique where actors create a living picture, freezing in dynamic poses to convey emotions and pivotal moments in the narrative. This technique has been particularly prominent in classical theater, where a single scene can encapsulate the essence of a play. The tableau vivant, or living picture, engages the audience's imagination, compelling them to derive meaning from the stillness and the relationships portrayed among the characters. This method not only enhances the visual experience of the performance but also deepens the audience's emotional engagement with the story.

  • Cellulose is the most frequent polysaccharide in nature consisting of (some hundreds up to ten thousands) β-glycosidic linked glucose molecules. It is the main constituent of plant cell walls and vegetable fibre. It occurs mostly associated with hemicelluloses and lignin. It is therefore a common component of plant-based feed for all food producing and companion animals. However, these animals are not capable to digest cellulose enzymatically due to the lack of cellulases. The monomer element of cellulose, glucose, will not be released from cellulose. But gastrointestinal microbes can split cellulose, the main degradation products are short-chain fatty acids. In a simplified view, monogastric animals cannot digest cellulose, small amounts are microbially degraded in the large intestine. Minor amounts of cellulose may be absorbed as such by paracellular transport (passing through the intercellular space) or by transcytosis (transcellular transport of macromolecules captured in vesicles). On the other side, animals with large fermentation chambers in the intestine, such as ruminants, horses and rabbits, utilise large amounts of cellulose as energy source. In summary, cellulose is a natural part of feed and plays a physiological role in nutrition of animals (see Section 3.2.1).

  • HPMC, a semi-synthetic derivative of cellulose, comes in different grades that primarily vary by their molecular weight and degree of substitution. These variations have a profound impact on the rheological properties, particularly viscosity. Higher molecular weight grades typically result in higher viscosities when dissolved in water or other solvents. This is because larger molecules interact more extensively, creating a more viscous solution. Conversely, lower molecular weight grades produce less viscous solutions due to reduced molecular entanglement.
