Riesling grapes are naturally very high in acid, and the cool, northern climate of Germany means this ripping acid stays in the grapes even into the fall harvest season. So winemakers let the fermentations stop before the wine is completely dry, retaining a little sweetness in order to strike balance in the wine.
Oxygenation refers to the process of adding oxygen to the body system. There is no way to reliably measure arterial oxygenation via clinical signs alone. Cyanosis, pallor and other physical findings are not reliable.
Fixation (histology) In the fields of histology, pathology, and cell biology, fixation is a critical step in the preparation of histological sections by which biological tissues are preserved from decay, thereby preventing autolysis or putrefaction. The structure of a tissue is determined by the shapes and sizes of macromolecules in and around cells. The principal macromolecules inside a cell are proteins and nucleic acids. Fixation terminates any ongoing biochemical reactions, and may also increase the mechanical s
